                              [POLARIS II LOGO]


THIS PROFILE IS A SUMMARY OF SOME OF THE MORE IMPORTANT POINTS THAT YOU SHOULD
KNOW AND CONSIDER BEFORE PURCHASING THE POLARIS(II) VARIABLE ANNUITY. THE
ANNUITY IS MORE FULLY DESCRIBED IN THE PROSPECTUS. PLEASE READ THE PROSPECTUS
CAREFULLY.

                                  July 5, 2000


----------------------------------------------------------------
----------------------------------------------------------------
                      1. THE POLARIS(II) VARIABLE ANNUITY
----------------------------------------------------------------
----------------------------------------------------------------

The Polaris(II) Variable Annuity is a contract between you and Anchor National
Life Insurance Company. It is designed to help you invest on a tax-deferred
basis and meet long-term financial goals, such as retirement funding. Tax
deferral means all your money, including the amount you would otherwise pay in
current income taxes, remains in your contract to generate more earnings. Your
money could grow faster than it would in a comparable taxable investment.


Polaris(II) offers a diverse selection of money managers, investment options and
other programs. You may divide your money among any or all 31 variable
portfolios and 5 fixed account options. Additionally, if you do not elect to
participate in the Principal Rewards Program, you may also allocate money to the
2 dollar cost averaging ("DCA") fixed account options. To the extent you invest
in the variable portfolios, your investment is not guaranteed. The value of your
Polaris(II) contract can fluctuate up and down, based on the performance of the
underlying investments you select and you may experience a loss.


The variable portfolios offer professionally managed investment choices with
goals ranging from capital preservation to aggressive growth. Your choices for
the various investment options are found on the next page.

The contract also offers 5 fixed account options and, if you do not elect to
participate in the Principal Rewards Program, 2 DCA fixed account options for
different time periods. Each may have a different interest rate. Interest rates
are guaranteed by Anchor National.

Like most annuities, the contract has an accumulation phase and an income phase.
During the accumulation phase, you invest money in your contract. Your earnings
are based on the investment performance of the variable portfolios to which your
money is allocated and/or the interest rate(s) earned on the fixed account
option(s) in which you invest. You may withdraw money from your contract during
the accumulation phase. However, as with other tax-deferred investments, you
will pay taxes on earnings and untaxed contributions when you withdraw them. A
federal tax penalty may apply if you make withdrawals before age 59 1/2.

During the income phase, you may receive income payments from your annuity. Your
income payments may be fixed in dollar amount, vary with investment performance
or a combination of both, depending on where your money is allocated. Among
other factors, the amount of money you are able to accumulate in your contract
during the accumulation phase will affect the amount of your income payments
during the income phase.
----------------------------------------------------------------
----------------------------------------------------------------
                               2. INCOME OPTIONS
----------------------------------------------------------------
----------------------------------------------------------------

You can select from one of five income options:

   (1) payments for your lifetime;

   (2) payments for your lifetime and your survivor's lifetime;

   (3) payments for your lifetime and your survivor's lifetime, but for not less
       than 10 or 20 years;

   (4) payments for your lifetime, but for not less than 10 or 20 years; and

   (5) payments for a specified period of 5 to 30 years.

You will also need to decide when your income payments begin and if you want
your income payments to fluctuate with investment performance or remain
constant. Once you begin receiving income payments, you cannot change your
income option.

If your contract is part of a non-qualified retirement plan (one that is
established with after-tax dollars), payments during the income phase are
considered partly a return of your original investment. The "original
investment" part of each payment is not taxable as income. For contracts which
are part of a qualified retirement plan using before-tax dollars, the entire
income payment is taxable as income.

In addition to the above income options, you may elect to take income payments
under the income protector feature, subject to the provisions thereof.
----------------------------------------------------------------
----------------------------------------------------------------
                      3. PURCHASING A POLARIS(II) VARIABLE
                                ANNUITY CONTRACT
----------------------------------------------------------------
----------------------------------------------------------------

You can buy a contract through your financial representative, who can also help
you complete the proper forms. For non-qualified contracts, the minimum initial
purchase payment is $5,000 and subsequent amounts of $500 or more may be added
to your contract at any time during the accumulation phase. For qualified
contracts, the minimum initial purchase payment is $2,000 and subsequent amounts
of $250 or more may be added to your contract at any time during the
accumulation phase.
<PAGE>   3

You may elect to participate in the Principal Rewards Program when you apply for
your contract. Under this program, we add an amount to your contract (an
"initial payment enhancement") each time you invest a purchase payment.
Additionally, we may also pay an amount to your contract at a future date (a
"deferred payment enhancement"). Payment enhancement amounts are calculated as a
percentage of each purchase payment. The Principal Rewards Program may not be
available to you. Please check with your financial representative regarding
availability of this program.

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

                             4. INVESTMENT OPTIONS
                ----------------------------------------------------------------

and 10-year market value adjustment ("MVA") fixed account options and, under
certain circumstances, the 6-month and 1-year DCA fixed account options.

The interest rates applicable for these fixed account options may differ from
time to time, however, we will never credit less than a 3% annual effective
rate. Once established, the rate will not change during the selected period.
Your contract value will be adjusted up or down for withdrawals or transfers
from the 3, 5, 7 and 10-year fixed account options prior to the end of the
guarantee period.
----------------------------------------------------------------
----------------------------------------------------------------
                                  5. EXPENSES
                ----------------------------------------------------------------
                ----------------------------------------------------------------

Each year, we deduct a $35 contract maintenance fee ($30 in North Dakota) from
your contract. We also deduct insurance charges which equal 1.52% annually of
the average daily value of your contract allocated to the variable portfolios.

As with other professionally managed investments, there are investment charges
imposed on contracts with money allocated to the variable portfolios. We
estimate these fees to range from .53 to 1.90.

If you take money out of your contract, you may be assessed a withdrawal charge
which is a percentage of purchase payments. The percentage declines over the
time the money is in the contract. The withdrawal charge schedule also varies
dependent upon whether you elect to participate in the Principal Rewards Program
when you purchase your contract. The two withdrawal charge schedules are as
follows:

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

Each year, you are allowed to make 15 transfers without charge. After your first
15 free transfers, a $25 transfer fee ($10 in Pennsylvania and Texas) applies to
each subsequent transfer.

In a limited number of states, you may also be charged for a state premium tax
of up to 3.5% depending upon the state.

The following chart is designed to help you understand the charges in your
contract. The column "Total Annual Charges" shows the total of the 1.52%
insurance charges, the $35 contract maintenance fee and the investment charges
for each variable portfolio. We converted the contract maintenance fee to a
percentage using an assumed contract
<PAGE>   4

size of $40,000. The actual impact of this charge on your contract may differ
from this percentage.

The next two columns show two examples of the charges you would pay under the
contract. The examples assume that you invested $1,000 in a contract which earns
5% annually and that you withdraw your money: (1) at the end of year 1, and (2)
at the end of year 10. The premium tax is assumed to be 0% in both examples.

                                    6. TAXES
                ----------------------------------------------------------------
                ----------------------------------------------------------------

Unlike taxable investments where earnings are taxed in the year they are earned,
taxes on amounts earned in a non-qualified contract are deferred until they are
withdrawn. In a qualified contract, all amounts are taxable when they are
withdrawn.

When you begin taking distributions or withdrawals from your contract, earnings
are considered to be taken out first and will be taxed at your ordinary income
rate. You may be subject to a 10% federal tax penalty for distributions or
withdrawals before age 59 1/2.
                ----------------------------------------------------------------
                ----------------------------------------------------------------
                            7. ACCESS TO YOUR MONEY
                ----------------------------------------------------------------
                ----------------------------------------------------------------

During the first year, you may withdraw free of a withdrawal charge an amount
that is equal to the penalty-free earnings in your contract as of the date you
make the withdrawal or, if you participate in the systematic withdrawal program,
you may withdraw 10% of your total invested amount less any withdrawals made
during the year. The penalty-free earnings amount is calculated by taking the
value of your contract on the day you make the withdrawal and subtracting your
total invested amount. After the first year, your maximum free withdrawal amount
is the greater of: (1) the penalty-free earnings or (2) 10% of your total
invested amount that has been invested for at least one year, less any
withdrawals
<PAGE>   5

made during the year. Withdrawals in excess of these limits will be assessed a
withdrawal charge.

If you withdraw your entire contract value, you will not receive the benefit of
any free withdrawal amount. After a purchase payment has been in the contract
for seven years, or nine years if you participate in the principal rewards
program, there are no withdrawal charges on that purchase payment.

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

When you invest in the Polaris(II) Variable Annuity, your money is actually
invested in the underlying portfolios of the Anchor Series Trust and/or the
SunAmerica Series Trust. The value of your annuity will fluctuate depending upon
the investment performance of the portfolio(s) you choose.

The following chart shows total returns for each portfolio for the time periods
shown. These numbers reflect the insurance charges, the contract maintenance fee
and the investment charges. Withdrawal charges are not reflected in the chart.
Past performance is no guarantee of future results.

                                9. DEATH BENEFIT
                ----------------------------------------------------------------
                ----------------------------------------------------------------

If you should die during the accumulation phase, your beneficiary will receive a
death benefit. You must select from the two death benefit options described
below at the time you purchase your contract. Once selected, your death benefit
may not be changed. You should discuss with your financial representative the
options available to you and which option is best for you.

     OPTION 1 - PURCHASE PAYMENT ACCUMULATION OPTION:

The death benefit is the greater of:

(1) the value of your contract at the time we receive satisfactory proof of
    death; or

(2) total purchase payments less withdrawals (and any fees or charges applicable
    to such withdrawals), compounded at a 4% annual growth rate until the date
    of death (3% growth rate if 70 or older at the time of contract issue) plus
    any purchase payments less withdrawals recorded after the date of death (and
    any fees or charges applicable to such withdrawals); or

(3) the value of your contract on the seventh contract anniversary, plus any
    purchase payments since the seventh anniversary and less any withdrawals
    (and any fees or charges applicable to such withdrawals), all compounded at
    a 4% annual growth rate until the date of death (3% if 70 or older at the
    time of contract issue) plus any purchase payments less withdrawals recorded
    after the date of death (and any fees or charges applicable to such
    withdrawals).

     OPTION 2 - MAXIMUM ANNIVERSARY OPTION:

The death benefit is the greater of:

(1) the value of your contract at the time we receive satisfactory proof of
    death; or

(2) total purchase payments less any withdrawals (and any fees or charges
    applicable to such withdrawals); or

(3) the maximum anniversary value on any contract anniversary prior to your 81st
    birthday. The anniversary value equals the value of your contract on a
    contract anniversary plus any purchase payments and less any withdrawals
    (and any fees or charges applicable to such withdrawals) since that
    anniversary.

If you participate in the principal rewards program and die prior to a deferred
payment enhancement date, we will not allocate the corresponding deferred
payment enhancement(s) to your contract.

If you are age 90 or older at the time of death and selected the option 2 death
benefit, the death benefit will be equal to the value of your contract at the
time we receive satisfactory proof of death.

                             10. OTHER INFORMATION
                ----------------------------------------------------------------
                ----------------------------------------------------------------

FREE LOOK: You may cancel your contract within ten days (or longer if required
by your state) by mailing it to our Annuity Service Center. Your contract will
be treated as void on the date we receive it and we will pay you an amount equal
to the value of your contract on the day we receive your request (unless
otherwise required by state law) less the free look

payment enhancement deduction. The amount returned to you may be more or less
than the money you initially invested.

PRINCIPAL REWARDS PROGRAM: If elected by you, we add an amount to your contract
(an "upfront payment enhancement") each time you submit a purchase payment.
Additionally, we may also add an amount to your contract at a future date (a
"deferred payment enhancement"). Payment enhancement amounts are calculated as a
percentage of your purchase payment amount and are treated as earnings under
your contract. The program may not be available to you. Please check with your
financial representative regarding the availability of this program.

ASSET ALLOCATION REBALANCING PROGRAM: If elected by you, this program seeks to
keep your investment in line with your goals. We will maintain your specified
allocation mix in the variable portfolios and the 1-year fixed account option by
readjusting your money on a calendar quarter, semiannual or annual basis.

SYSTEMATIC WITHDRAWAL PROGRAM: If elected by you, this program allows you to
receive either monthly, quarterly, semiannual or annual checks during the
accumulation phase. Systematic withdrawals may also be electronically
transferred to your bank account. Of course, withdrawals may be taxable and a
10% federal tax penalty may apply if you are under age 59 1/2.

PRINCIPAL ADVANTAGE PROGRAM: If elected by you, this program allows you to
obtain growth potential without any market risk to your principal. We will
guarantee that the portion of your money allocated to the 1, 3, 5, 7 or 10-year
fixed account option will grow to equal your principal investment when it is
allocated in accordance with the program.

DOLLAR COST AVERAGING: If elected by you, this program allows you to invest
gradually in the variable portfolios from any of the variable portfolios or the
1-year fixed account option. You may also invest in the variable portfolios from
the 6-month DCA fixed account option or the 1-year DCA fixed account option if
you do not participate in the principal rewards program.

AUTOMATIC PAYMENT PLAN: You can add to your contract directly from your bank
account with as little as $20 per month.

CONFIRMATIONS AND QUARTERLY STATEMENTS: During the accumulation phase, you will
receive confirmation of transactions within your contract. Transactions made
pursuant to contractual or systematic agreements, such as deduction of the
annual maintenance fee and dollar cost averaging, may be confirmed quarterly.
Purchase payments received through the automatic payment plan or a salary
reduction arrangement, may also be confirmed quarterly. For all other
transactions, we send confirmations immediately.

During the accumulation and income phases, you will receive a statement of your
transactions over the past quarter and a summary of your account values.

         SECURITIES AND EXCHANGE COMMISSION POSITION ON INDEMNIFICATION
----------------------------------------------------------------
----------------------------------------------------------------

Indemnification for liabilities arising under the Securities Act of 1933 (the
"Act") is provided to Anchor National's officers, directors and controlling
persons. The SEC has advised that it believes such indemnification is against
public policy under the Act and unenforceable. If a claim for indemnification
against such liabilities (other than for Anchor National's payment of expenses
incurred or paid by its directors, officers or controlling persons in the
successful defense of any legal action) is asserted by a director, officer or
controlling person of Anchor National in connection with the securities
registered under this prospectus, Anchor National will submit to a court with
jurisdiction to determine whether the indemnification is against public policy
under the Act. Anchor National will be governed by final judgment of the issue.
However, if in the opinion of Anchor National's counsel, this issue has been
determined by controlling precedent, Anchor National will not submit the issue
to a court for determination.

EXPLANATION OF FEE TABLES AND EXAMPLES

1.  The purpose of the Fee Tables is to show you the various expenses you would
    incur directly and indirectly by investing in the contract.

2.  For certain Variable Portfolios, the adviser, SunAmerica Asset Management
    Corp., has voluntarily agreed to waive fees or reimburse certain expenses,
    if necessary, to keep annual operating expenses at or below the lesser of
    the maximum allowed by any applicable state expense limitations or the
    following percentages of each Variable Portfolio's average net assets:
    SunAmerica Balanced (1.00%); "Dogs" of Wall Street (.85%); Aggressive Growth
    (.90%); Federated Value (1.03%); Utility (1.05%); Emerging Markets (1.90%);
    International Growth and Income (1.60%); and Real Estate (1.25%). The
    adviser also may voluntarily waive or reimburse additional amounts to
    increase a Variable Portfolio's investment return. All waivers and/or
    reimbursements may be terminated at any time. Furthermore, the adviser may
    recoup any waivers or reimbursements within two years after such waivers or
    reimbursements are granted, provided that the Variable Portfolio is able to
    make such payment and remain in compliance with the foregoing expense
    limitations.

3.  The Examples assume that no transfer fees were imposed. Although premium
    taxes may apply in certain states, they are not reflected in the Examples.

4.  Examples reflecting participation in the Principal Rewards program reflect
    surrender charge Schedule B, and a 2% upfront payment enhancement.

5.  THESE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

THE HISTORICAL ACCUMULATION UNIT VALUES ARE CONTAINED IN APPENDIX A -- CONDENSED
                             FINANCIAL INFORMATION.

                        THE POLARIS(II) VARIABLE ANNUITY
----------------------------------------------------------------
----------------------------------------------------------------

An annuity is a contract between you and an insurance company. You are the owner
of the contract. The contract provides three main benefits:

     - Tax Deferral: This means that you do not pay taxes on your earnings from
       the annuity until you withdraw them.

     - Death Benefit: If you die during the Accumulation Phase, the insurance
       company pays a death benefit to your Beneficiary.

     - Guaranteed Income: If elected, you receive a stream of income for your
       lifetime, or another available period you select.

Tax-qualified retirement plans (e.g., IRAs, 401(k) or 403(b) plans) defer
payment of taxes on earnings until withdrawal. If you are considering funding a
tax-qualified retirement plan with an annuity, you should know that an annuity
does not provide any additional tax deferral treatment of earnings beyond the
treatment provided by the tax-qualified retirement plan itself. However,
annuities do provide other features and benefits which may be valuable to you.
You should fully discuss this decision with your financial representative.

This annuity was developed to help you contribute to your retirement savings.
This annuity works in two stages, the Accumulation Phase and the Income Phase.
Your contract is in the Accumulation Phase during the period when you make
payments into the contract. The Income Phase begins when you request us to start
making income payments to you out of the money accumulated in your contract.


The contract is called a "variable" annuity because it allows you to invest in
variable portfolios which, like mutual funds, have different investment
objectives and performance which varies. You can gain or lose money if you
invest in these Variable Portfolios. The amount of money you accumulate in your
contract depends on the performance of the Variable Portfolios in which you
invest. This contract currently offers 31 Variable Portfolios.


The contract also offers several fixed account options for varying time periods.
Fixed account options earn interest at a rate set and guaranteed by Anchor
National. If you allocate money to the fixed account options, the amount of
money that accumulates in the contract depends on the total interest credited to
the particular fixed account option(s) in which you invest.

For more information on investment options available under this contract SEE
INVESTMENT OPTIONS ON PAGE 10.

This annuity is designed to assist in contributing to retirement savings of
investors whose personal circumstances allow for a long-term investment time
horizon. As a function of the Internal Revenue Code ("IRC"), you may be assessed
a 10% federal tax penalty on any withdrawal made prior to your reaching age
59 1/2. Additionally, this contract provides that you will be charged a
withdrawal charge on each purchase payment withdrawn if that purchase payment
has not been invested in this contract for at least 7 years, or 9 years if you
elect to participate in the Principal Rewards Program. Because of these
potential penalties, you should fully discuss all of the benefits and risks of
this contract with your financial representative prior to purchase.

                   PURCHASING A POLARIS(II) VARIABLE ANNUITY

An initial Purchase Payment is the money you give us to buy a contract. Any
additional money you give us to invest in the contract after purchase is a
subsequent Purchase Payment.

The following chart shows the minimum initial and subsequent Purchase Payments
permitted under your contract. These amounts depend upon whether a contract is
Qualified or Non-qualified for tax purposes. FOR FURTHER EXPLANATION, SEE TAXES
ON PAGE 20.

</TABLE>

Prior Company approval is required to accept Purchase Payments greater than
$1,500,000. The Company reserves the right to refuse any Purchase Payment
including one which would cause the contract value or total Purchase Payments to
exceed $1,500,000 at the time of the Purchase Payment. Also, the optional
automatic payment plan allows you to make subsequent Purchase Payments of as
little as $20.00.

In general, we will not issue a Qualified contract to anyone who is age 70 1/2
or older, unless it is shown that the minimum distribution required by the IRS
is being made. In addition, we may not issue a contract to anyone over age 90.
You may not elect to participate in the Principal Rewards Program if you are
over age 80 at the time of contract issue.

ALLOCATION OF PURCHASE PAYMENTS

We invest your Purchase Payments in the fixed and variable investment options
according to your instructions. If we receive a Purchase Payment without
allocation instructions, we will invest the money according to your last
allocation instructions. SEE INVESTMENT OPTIONS ON PAGE 10.

In order to issue your contract, we must receive your completed application,
Purchase Payment allocation instructions and any other required paperwork at our
principal place of business. We allocate your initial Purchase Payment within
two days of receiving it. If we do not have complete information necessary to
issue your contract, we will contact you. If we do not have the information
necessary to issue your contract within 5 business days we will:

     - Send your money back to you, or;

     - Ask your permission to keep your money until we get the information
       necessary to issue the contract.

PRINCIPAL REWARDS PROGRAM


If you elect to participate in the Principal Rewards program at contract issue,
we contribute an Upfront Payment Enhancement and, if applicable, a Deferred
Payment Enhancement to your contract in conjunction with each Purchase Payment
you invest during the life of your contract. If you elect to participate in this
program, all Purchase Payments are subject to a nine year withdrawal charge
schedule. SEE WITHDRAWAL CHARGES ON PAGE 17. You may not elect to participate in
this program if you are over age 80 at the time of contract issue. Amounts we
contribute to your contract under this program are considered earnings and are
allocated to your contract as described below.


Purchase Payments may not be invested in the 6-month or the 1-year Dollar Cost
Averaging fixed accounts if you participate in the Principal Rewards Program.
However, you may use the 1-year fixed account option as a Dollar Cost Averaging
source account.

Enhancement Levels

The Upfront Payment Enhancement Rate, Deferred Payment Enhancement Rate and
Deferred Payment Enhancement Date may be determined based on stated Enhancement
Levels. Each Enhancement Level is a range of dollar amounts which may correspond
to different enhancement rates and dates. Enhancement Levels may change from
time to time, at our sole discretion. The Enhancement Level applicable to your
initial Purchase Payment is determined by the amount of that initial Purchase
Payment. With respect to any subsequent Purchase Payments we determine your
Enhancement Level by adding your contract value on the date we receive each
subsequent Purchase Payment plus the amount of the subsequent Purchase Payment.

Upfront Payment Enhancement

An Upfront Payment Enhancement is an amount we add to your contract on the day
we receive a Purchase Payment. We calculate an Upfront Payment Enhancement
amount as a percentage (the "Upfront Payment Enhancement Rate") of each Purchase
Payment. The Upfront Payment Enhancement Rate will always be at least 2%. We
periodically review and establish the Upfront Payment Enhancement Rate, which
may increase or decrease at any time, but will never be less than 2%. The
applicable Upfront Payment Enhancement Rate is that which is in effect for any
applicable Enhancement Level, when we receive each Purchase Payment under your
contract. The Upfront Payment Enhancement amounts are allocated among the fixed
and variable investment options according to the current allocation instructions
in effect when we receive each Purchase Payment.

Deferred Payment Enhancement

A Deferred Payment Enhancement is an amount we may add to your contract on a
future date (the "Deferred Payment Enhancement Date"). We calculate the Deferred
Payment Enhancement amount, if any, as a percentage of each Purchase Payment
(the "Deferred Payment Enhancement Rate"). We periodically review and establish
the Deferred Payment Enhancement Rates and Deferred Payment Enhancement Dates.
The Deferred Payment Enhancement Rate being offered may increase, decrease or be
eliminated by

                                        8
<PAGE>   15

us, at any time. The Deferred Payment Enhancement Date, if applicable, may
change at any time. The applicable Deferred Payment Enhancement Date and
Deferred Payment Enhancement Rate are those which may be in effect for any
applicable Enhancement Level, when we receive each Purchase Payment under your
contract. Any applicable Deferred Payment Enhancement, when credited, is
allocated to the Cash Management Variable Portfolio.

If you withdraw any portion of a Purchase Payment, to which a Deferred Payment
Enhancement applies, prior to the Deferred Payment Enhancement Date, we reduce
the amount of the corresponding Deferred Payment Enhancement in the same
proportion that your withdrawal (and any fees and charges associated with such
withdrawals) reduces that Purchase Payment. For purposes of the Deferred Payment
Enhancement, withdrawals are assumed to be taken from earnings first, then from
Purchase Payments, on a first-in-first-out basis.

APPENDIX B shows how we calculate any applicable Deferred Payment Enhancement
amount.

We will not allocate any applicable Deferred Payment Enhancement to your
contract if any of the following circumstances occurs prior to the Deferred
Payment Enhancement Date:

     - You surrender your contract;

     - A death benefit is paid on your contract;

     - You switch to the Income Phase of your contract; or

     - You fully withdraw the corresponding Purchase Payment.

90 Day Window


Contracts issued with the Principal Rewards feature after April 3, 2000, may be
eligible for a "Look-Back Adjustment." As of the 90th day after your contract
was issued, we will total your Purchase Payments made over those 90 days,
without considering any investment gain or loss in contract value on those
Purchase Payments. If your total Purchase Payments bring you to an Enhancement
Level which, as of the date we issued your contract, would have provided for a
higher Upfront and/or Deferred Payment Enhancement Rate on each Purchase
Payment, you will get the benefit of the Enhancement Rate(s) that were
applicable to that higher Enhancement Level at the time your contract was
issued. We will add any applicable Upfront Look Back Adjustment to your contract
on the 90th day following the date of contract issue. We will send you a
confirmation indicating any applicable Upfront and/or Deferred Look Back
Adjustment, on or about the 90th day following the date of contract issuance. We
will allocate any applicable Upfront Look Back Adjustment according to your
then-current allocation instructions on file for subsequent Purchase Payments at
the time we make the contribution and if applicable, to the Cash Management
Portfolio, for a Deferred Look Back Adjustment.


APPENDIX B provides an example of the 90 Day Window Provision.

ACCUMULATION UNITS

When you allocate a Purchase Payment to the Variable Portfolios, we credit your
contract with Accumulation Units of the separate account. We base the number of
Accumulation Units you receive on the unit value of the Variable Portfolio as of
the day we receive your money if we receive it before 1 p.m. Pacific Standard
Time, or on the next business day's unit value if we receive your money after 1
p.m. Pacific Standard Time. The value of an Accumulation Unit goes up and down
based on the performance of the Variable Portfolios.

We calculate the value of an Accumulation Unit each day that the New York Stock
Exchange ("NYSE") is open as follows:

     1. We determine the total value of money invested in a particular Variable
        Portfolio;

     2. We subtract from that amount all applicable contract charges; and

     3. We divide this amount by the number of outstanding Accumulation Units.

We determine the number of Accumulation Units credited to your contract by
dividing the Purchase Payment and Payment Enhancement, if applicable, by the
Accumulation Unit value for the specific Variable Portfolio.

     EXAMPLE (CONTRACTS WITHOUT PRINCIPAL REWARDS):

     We receive a $25,000 Purchase Payment from you on Wednesday. You allocate
     the money to the Global Bond Portfolio. We determine that the value of an
     Accumulation Unit for the Global Bond Portfolio is $11.10 when the NYSE
     closes on Wednesday. We then divide $25,000 by $11.10 and credit your
     contract on Wednesday night with 2252.2523 Accumulation Units for the
     Global Bond Portfolio.

     EXAMPLE (CONTRACTS WITH PRINCIPAL REWARDS):

     We receive a $25,000 Purchase Payment from you on Wednesday. You allocate
     the money to the Global Bond Portfolio. If the Upfront Payment Enhancement
     is 2.00% of your Purchase Payment, we would add an Upfront Payment
     Enhancement of $500 to your contract. We determine that the value of an
     Accumulation Unit for the Global Bond Portfolio is $11.10 when the NYSE
     closes on Wednesday. We then divide $25,500 by $11.10 and credit your
     contract on Wednesday with 2,297.2973 Accumulation Units for the Global
     Bond Portfolio.

Performance of the Variable Portfolios and expenses under your contract affect
Accumulation Unit values. These factors cause the value of your contract to go
up and down.

FREE LOOK

You may cancel your contract within ten days after receiving it (or longer if
required by state law). We call this a "free look." To cancel, you must mail the
contract along with your free look request to our Annuity Service Center at P.O.
Box 54299, Los Angeles, California 90054-0299.

If you decide to cancel your contract during the free look period, we will
refund to you the value of your contract on the day we receive your request
minus the Free Look Payment Enhancement Deduction, if applicable. The Free Look
Payment Enhancement Deduction is equal to the lesser of (1) the value of any
Payment Enhancement(s) on the day we receive your free look request; or (2) the
Payment Enhancement amount(s), if any, which we allocated to your contract.
Thus, you receive any gain and we bear any loss on any Payment Enhancement(s) if
you decide to cancel your contract during the free look period.

Certain states require us to return your Purchase Payments upon a free look
request. Additionally, all contracts issued as an IRA require the full return of
Purchase Payments upon a free look. With respect to those contracts, we reserve
the right to put your money in the Cash Management Portfolio during the free
look period and will allocate your money according to your instructions at the
end of the applicable free look period. Currently, we do not put your money in
the Cash Management Portfolio during the free look period unless you allocate
your money to it. If your contract was issued in a state requiring return of
Purchase Payments or as an IRA and you cancel your contract during the free look
period, we return the greater of (1) your Purchase Payments; or (2) the value of
your contract minus the Free Look Payment Enhancement Deduction, if applicable.

VARIABLE PORTFOLIOS


The contract currently offers 31 Variable Portfolios. These Variable Portfolios
invest in shares of the Anchor Series Trust and the SunAmerica Series Trust (the
"Trusts"). Additional Variable Portfolios may be available in the future. The
Variable Portfolios operate similar to a mutual fund but are only available
through the purchase of certain insurance contracts.


SunAmerica Asset Management Corp., an indirect wholly owned subsidiary of AIG,
is the investment adviser to the Trusts. The Trusts serve as the underlying
investment vehicles for other variable annuity contracts issued by Anchor
National, and other affiliated/unaffiliated insurance companies. Neither Anchor
National nor the Trusts believe that offering shares of the

                                       10

FIXED ACCOUNT OPTIONS


The contract also offers seven fixed account options. Anchor National will
guarantee the interest rate earned on money you allocate to any of these fixed
account options. We currently offer fixed account options for periods of one,
three, five, seven and ten years, which we call guarantee periods. If you do not
elect to participate in the Principal Rewards Program, you also have the option
of allocating your money to the 6-month DCA fixed account and/or the 1-year DCA
fixed account (the "DCA fixed accounts") which are available in conjunction with
the Dollar Cost Averaging Program. The 6-month and 1-year DCA fixed account
options are not available to you if you elect to participate in the Principal
Rewards Program. Please see the section on DOLLAR COST AVERAGING ON PAGE 13 for
additional information about, including limitations on, and the availability and
operation of the DCA fixed accounts. The DCA fixed accounts are only available
for new Purchase Payments. Policyholders in Pennsylvania who elect the Principal
Rewards Program cannot use the multi-year MVA fixed accounts.


Each guarantee period may offer a different interest rate but will never be less
than an annual effective rate of 3%. Once established the rates for specified
payments do not change during the guarantee period. The guarantee period is that
period for which we credit the applicable rate (one, three, five, seven or ten
years).

There are three scenarios in which you may put money into the fixed account
options other than the DCA fixed accounts options. In each scenario your money
may be credited a different rate of interest as follows:

     - Initial Rate: Rate credited to amounts allocated to the fixed account
       when you purchase your contract.

     - Current Rate: Rate credited to subsequent amounts allocated to the fixed
       account.

     - Renewal Rate: Rate credited to money transferred from a fixed account or
       a Variable Portfolio into a fixed account and to money remaining in a
       fixed account after expiration of a guarantee period.

Each of these rates may differ from one another. Once declared, the applicable
rate is guaranteed until the corresponding guarantee period expires.

When a guarantee period ends, you may leave your money in the same fixed
investment option. You may also reallocate your money to another fixed
investment option (other than the DCA fixed accounts) or to the Variable
Portfolios. If you want to reallocate your money to a different fixed account
option or a

                                       11
<PAGE>   18

Variable Portfolio, you must contact us within 30 days after the end of the
current interest guarantee period and instruct us how to reallocate the money.
We do not contact you. If we do not hear from you, your money will remain in the
same fixed account option, where it will earn interest at the renewal rate then
in effect for the fixed account option.


The DCA fixed accounts also credit a fixed rate of interest. Interest is
credited to amounts allocated to the 6-month or 1-year DCA fixed account while
your investment is systematically transferred to the Variable Portfolios. The
rates applicable to the DCA fixed accounts may differ from each other and/or the
other fixed account options but will never be less than an annual effective rate
of 3%. See DOLLAR COST AVERAGING ON PAGE 13 for more information.


MARKET VALUE ADJUSTMENT ("MVA")

NOTE: THE FOLLOWING DISCUSSION APPLIES TO THE 3, 5, 7 AND 10-YEAR FIXED ACCOUNT
OPTIONS ONLY. THESE OPTIONS ARE NOT AVAILABLE IN ALL STATES. PLEASE CONTACT YOUR
FINANCIAL REPRESENTATIVE FOR MORE INFORMATION.

If you take money out of the multi-year fixed account options before the end of
the guarantee period, we make an adjustment to your contract. We refer to the
adjustment as a market value adjustment (the "MVA"). The MVA reflects any
difference in the interest rate environment between the time you place your
money in the fixed account option and the time when you withdraw or transfer
that money. This adjustment can increase or decrease your contract value. You
have 30 days after the end of each guarantee period to reallocate your funds
without incurring any MVA.

We calculate the MVA by doing a comparison between current rates and the rate
being credited to you in the fixed account option. For the current rate we use a
rate being offered by us for a guarantee period that is equal to the time
remaining in the guarantee period from which you seek withdrawal. If we are not
currently offering a guarantee period for that period of time, we determine an
applicable rate by using a formula to arrive at a number between the interest
rates currently offered for the two closest periods available.

Generally, if interest rates drop between the time you put your money into the
fixed account options and the time you take it out, we credit a positive
adjustment to your contract. Conversely, if interest rates increase during the
same period, we post a negative adjustment to your contract.

Where the MVA is negative, we first deduct the adjustment from any money
remaining in the fixed account option. If there is not enough money in the fixed
account option to meet the negative deduction, we deduct the remainder from your
withdrawal. Where the MVA is positive, we add the adjustment to your withdrawal
amount.

The multi-year MVA fixed accounts are not available to Washington state
policyholders who select the Principal Rewards Program.

Anchor National does not assess a MVA against withdrawals under the following
circumstances:

     - If made within 30 days after the end of a guarantee period;
     - If made to pay contract fees and charges;
     - To pay a death benefit; and
     - Upon annuitization, if occurring on the latest Annuity Date.

APPENDIX C shows how we calculate the MVA.

TRANSFERS DURING THE ACCUMULATION PHASE

During the Accumulation Phase you may transfer funds between the Variable
Portfolios and/or the fixed account options. Funds already in your contract
cannot be transferred into the DCA fixed accounts. You must transfer at least
$100. If less than $100 will remain in any Variable Portfolio after a transfer,
that amount must be transferred as well.

You may request transfers of your account value between the Variable Portfolios
and/or the fixed account options in writing or by telephone. Additionally, you
may access your account and request transfers between Variable Portfolios and/or
the fixed account options through SunAmerica's website
(http://www.sunamerica.com). We currently allow 15 free transfers per contract
per year. We charge $25 ($10 in Pennsylvania and Texas) for each additional
transfer in any contract year. Transfers resulting from your participation in
the DCA program count against your 15 free transfers per contract year. However,
transfers resulting from your participation in the automatic asset rebalancing
program do not count against your 15 free transfers.

We accept transfer requests by telephone unless you tell us not to on your
contract application. Additionally, you may request transfers over the internet
unless you indicate you do not wish your account to be traded over the internet.
When receiving instructions over the telephone or the internet, we follow
appropriate procedures to provide reasonable assurance that the transactions
executed are genuine. Thus, we are not responsible for any claim, loss or
expense from any error resulting from instructions received over the telephone.
If we fail to follow our procedures, we may be liable for any losses due to
unauthorized or fraudulent instructions.

We may limit the number of transfers in any contract year or refuse any transfer
request for you or others invested in the contract if we believe that excessive
trading or a specific transfer request or group transfer requests may have a
detrimental effect on unit values or the share prices of the underlying Variable
Portfolios.

Where permitted by law, we may accept your authorization for a third party to
make transfers for you subject to our rules. We reserve the right to suspend or
cancel such acceptance at any time and will notify you accordingly.
Additionally, we may restrict the investment options available for transfers
during any period in which such third party acts for you. We notify such third
party beforehand regarding any restrictions. However, we will not enforce these
restrictions if we are satisfied that:

     - such third party has been appointed by a court of competent jurisdiction
       to act on your behalf; or
     - such third party is a trustee/fiduciary, for you or appointed by you, to
       act on your behalf for all your financial affairs.

                                       12
<PAGE>   19

We may provide administrative or other support services to independent third
parties you authorize to make transfers on your behalf. We do not currently
charge you extra for providing these support services. This includes, but is not
limited to, transfers between investment options in accordance with market
timing strategies. Such independent third parties may or may not be appointed
with us for the sale of annuities. However, WE DO NOT ENGAGE ANY THIRD PARTIES
TO OFFER INVESTMENT ALLOCATION SERVICES OF ANY TYPE. WE TAKE NO RESPONSIBILITY
FOR THE INVESTMENT ALLOCATION AND TRANSFERS TRANSACTED ON YOUR BEHALF BY SUCH
THIRD PARTIES OR FOR ANY INVESTMENT ALLOCATION RECOMMENDATIONS MADE BY SUCH
PARTIES.


For information regarding transfers during the Income Phase, SEE INCOME OPTIONS
ON PAGE 18.


We reserve the right to modify, suspend, waive or terminate these transfer
provisions at any time.

DOLLAR COST AVERAGING

The Dollar Cost Averaging ("DCA") program allows you to invest gradually in the
Variable Portfolios. Under the program you systematically transfer a set dollar
amount or percentage of portfolio value from one Variable Portfolio or the
1-year fixed account option (source accounts) to any other Variable Portfolio.
Transfers may be monthly or quarterly and count against your 15 free transfers
per contract year. You may change the frequency at any time by notifying us in
writing. The minimum transfer amount under the DCA program is $100, regardless
of the source account.

We also offer the 6-month and 1-year DCA fixed accounts exclusively to
facilitate this program. If you elected to participate in the Principal Rewards
Program, the 6-month and 1-year DCA fixed accounts are not available under your
contract. The DCA fixed accounts only accept new Purchase Payments. You cannot
transfer money already in your contract into these options. If you allocate new
Purchase Payments into a DCA fixed account, we transfer all your money allocated
to that account into the Variable Portfolios over the selected 6-month or 1-year
period. You cannot change the option or the frequency of transfers once
selected.

If allocated to the 6-month DCA fixed account, we transfer your money over a
maximum of 6 monthly transfers. We base the actual number of transfers on the
total amount allocated to the account. For example, if you allocate $500 to the
6-month DCA fixed account, we transfer your money over a period of five months,
so that each payment complies with the $100 per transfer minimum.

We determine the amount of the transfers from the 1-year DCA fixed account based
on

     - the total amount of money allocated to the account, and

     - the frequency of transfers selected.

For example, let's say you allocate $1,000 to the 1-year DCA fixed account. You
select monthly transfers. We completely transfer all of your money to the
selected investment options over a period of ten months.

You may terminate your DCA program at any time. If money remains in the DCA
fixed accounts, we transfer the remaining money to the 1-year fixed account
option, unless we receive different instructions from you. Transfers resulting
from a termination of this program do not count towards your 15 free transfers.

The DCA program is designed to lessen the impact of market fluctuations on your
investment. However, we cannot ensure that you will make a profit. When you
elect the DCA program, you are continuously investing in securities regardless
of fluctuating price levels. You should consider your tolerance for investing
through periods of fluctuating price levels.

We reserve the right to modify, suspend or terminate this program at any time.

     EXAMPLE:

     Assume that you want to gradually move $750 each quarter from the Cash
     Management Portfolio to the Aggressive Growth Portfolio over six quarters.
     You set up dollar cost averaging and purchase Accumulation Units at the
     following values:

<TABLE>
<CAPTION>
---------------------------------------------
                 ACCUMULATION       UNITS
   QUARTER           UNIT         PURCHASED
---------------------------------------------
<S>            <C>              <C>
      1             $ 7.50           100
      2             $ 5.00           150
      3             $10.00            75
      4             $ 7.50           100
      5             $ 5.00           150
      6             $ 7.50           100
---------------------------------------------
</TABLE>

     You paid an average price of only $6.67 per Accumulation Unit over six
     quarters, while the average market price actually was $7.08. By investing
     an equal amount of money each month, you automatically buy more
     Accumulation Units when the market price is low and fewer Accumulation
     Units when the market price is high. This example is for illustrative
     purposes only.

ASSET ALLOCATION REBALANCING PROGRAM

Earnings in your contract may cause the percentage of your investment in each
investment option to differ from your original allocations. The Automatic Asset
Rebalancing Program addresses this situation. At your election, we periodically
rebalance your investments in the Variable Portfolios to return your allocations
to their original percentages. Asset rebalancing typically involves shifting a
portion of your money out of an investment option with a higher return into an
investment option with a lower return.

At your request, rebalancing occurs on a quarterly, semiannual or annual basis.
Transfers made as a result of rebalancing do not count against your 15 free
transfers for the contract year.

                                       13
<PAGE>   20

We reserve the right to modify, suspend or terminate this program at any time.

     EXAMPLE:

     Assume that you want your initial Purchase Payment split between two
     Variable Portfolios. You want 50% in the Corporate Bond Portfolio and 50%
     in the Growth Portfolio. Over the next calendar quarter, the bond market
     does very well while the stock market performs poorly. At the end of the
     calendar quarter, the Corporate Bond Portfolio now represents 60% of your
     holdings because it has increased in value and the Growth Portfolio
     represents 40% of your holdings. If you had chosen quarterly rebalancing,
     on the last day of that quarter, we would sell some of your units in the
     Corporate Bond Portfolio to bring its holdings back to 50% and use the
     money to buy more units in the Growth Portfolio to increase those holdings
     to 50%.

PRINCIPAL ADVANTAGE PROGRAM

The Principal Advantage Program allows you to invest in one or more Variable
Portfolios without putting your principal at direct risk. The program
accomplishes this by allocating your investment strategically between the fixed
account options and Variable Portfolios. You decide how much you want to invest
and approximately when you want a return of principal. We calculate how much of
your Purchase Payment to allocate to the particular fixed account option to
ensure that it grows to an amount equal to your total principal invested under
this program. We invest the rest of your principal in the Variable Portfolio(s)
of your choice.

We reserve the right to modify, suspend or terminate this program at any time.

     EXAMPLE:

     Assume that you want to allocate a portion of your initial Purchase Payment
     of $100,000 to the fixed account option. You want the amount allocated to
     the fixed account option to grow to $100,000 in 7 years. If the 7-year
     fixed account option is offering a 5% interest rate, we will allocate
     $71,069 to the 7-year fixed account option to ensure that this amount will
     grow to $100,000 at the end of the 7-year period. The remaining $28,931 may
     be allocated among the Variable Portfolios, as determined by you, to
     provide opportunity for greater growth.

VOTING RIGHTS

Anchor National is the legal owner of the Trusts' shares. However, when a
Variable Portfolio solicits proxies in conjunction with a vote of shareholders,
we must obtain your instructions on how to vote those shares. We vote all of the
shares we own in proportion to your instructions. This includes any shares we
own on our own behalf. Should we determine that we are no longer required to
comply with these rules, we will vote the shares in our own right.

SUBSTITUTION
If underlying Trust portfolios become unavailable for investment, we may be
required to substitute shares of another underlying Trust portfolio. We will
seek prior approval of the SEC and give you notice before substituting shares.
----------------------------------------------------------------
----------------------------------------------------------------
                              ACCESS TO YOUR MONEY
----------------------------------------------------------------
----------------------------------------------------------------

You can access money in your contract in two ways:

     - by making a partial or total withdrawal, and/or;


     - by receiving income payments during the Income Phase. SEE INCOME OPTIONS
       ON PAGE 18.


Generally, we deduct a withdrawal charge applicable to any total or partial
withdrawal and a MVA if a partial withdrawal comes from the 3, 5, 7 or 10 year
fixed account options. If you withdraw your entire contract value, we also
deduct premium taxes and a contract maintenance fee. SEE EXPENSES ON PAGE 16.

Your contract provides for a free withdrawal amount each year. A free withdrawal
amount is the portion of your account that we allow you to take out each year
without being charged a surrender penalty. However, upon a future full surrender
of your contract we will recoup any withdrawal charges which would have been due
if your free withdrawal had not been free. Additionally, if you participate in
the Principal Rewards Program you will not receive your Deferred Payment
Enhancement if you fully withdraw a Purchase Payment or your contract value
prior to the corresponding Deferred Payment Enhancement Date. SEE PRINCIPAL
REWARDS PROGRAM ON PAGE 8.

Purchase payments, above and beyond the amount of your free withdrawal amount,
that are withdrawn prior to the end of the seventh or ninth year if you elect to
participate in the Principal Rewards Program will result in your paying a
penalty in the form of a surrender charge. The amount of the charge and how it
applies are discussed more fully below. SEE EXPENSES ON PAGE 16. You should
consider, before purchasing this contract, the effect this charge will have on
your investment if you need to withdraw more money than the free withdrawal
amount. You should fully discuss this decision with your financial
representative.

To determine your free withdrawal amount and your withdrawal charge, we refer to
two special terms. These are penalty free earnings and the total invested
amount.

The penalty-free earnings portion of your contract is simply your account value
less your total invested amount. The total invested amount is the total of all
Purchase Payments you have made into the contract less portions of some prior
withdrawals you made. The portions of prior withdrawals that reduce your total
invested amount are as follows:

     - Free withdrawals in any year that were in excess of your penalty-free
       earnings and were based on the part of the total invested amount that was
       no longer subject to withdrawal charges at the time of the withdrawal,
       and

                                       14
<PAGE>   21

     - Any prior withdrawals (including withdrawal charges on those withdrawals)
       of the total invested amount on which you already paid a surrender
       penalty.

When you make a withdrawal, we assume that it is taken from penalty-free
earnings first, then from the total invested amount on a first-in, first-out
basis. This means that you can also access your Purchase Payments which are no
longer subject to a withdrawal charge before those Purchase Payments which are
still subject to the withdrawal charge.

During the first year after we issue your contract your free withdrawal amount
is the greater of (1) your penalty-free earnings; and (2) if you are
participating in the Systematic Withdrawal program, a total of 10% of your total
invested amount. If you are a Washington resident, you may withdraw during the
first contract year, the greater of (1); (2); or (3) interest earnings from the
amounts allocated to the fixed account options, not previously withdrawn.

After the first contract year, you can take out the greater of the following
amounts each year (1) your penalty-free earnings and any portion of your total
invested amount no longer subject to withdrawal charges; and (2) 10% of the
portion of your total invested amount that has been in your contract for at
least one year. If you are a Washington resident, your maximum free withdrawal
amount, after the first contract year, is the greater of (1); (2); or (3)
interest earnings from amounts allocated to the fixed account options, not
previously withdrawn.

Although we do not assess a withdrawal charge when you take a 10% penalty-free
withdrawal, we will proportionally reduce the amount of any corresponding
Deferred Payment Enhancement.

We calculate charges due on a total withdrawal on the day after we receive your
request and your contract. We return to you your contract value less any
applicable fees and charges.

Under most circumstances, the partial withdrawal minimum is $1,000. We require
that the value left in any investment option be at least $100, after the
withdrawal. You must send a written withdrawal request. Unless you provide us
with different instructions, partial withdrawals will be made pro rata from each
Variable Portfolio and the fixed account option in which your contract is
invested.

Under certain Qualified plans, access to the money in your contract may be
restricted. Additionally, withdrawals made prior to age 59 1/2 may result in a
10% IRS penalty tax. SEE TAXES ON PAGE 20.

We may be required to suspend or postpone the payment of a withdrawal for any
period of time when: (1) the NYSE is closed (other than a customary weekend and
holiday closings); (2) trading with the NYSE is restricted; (3) an emergency
exists such that disposal of or determination of the value of shares of the
Variable Portfolios is not reasonably practicable; (4) the SEC, by order, so
permits for the protection of contract owners.

Additionally, we reserve the right to defer payments for a withdrawal from a
fixed account in option. Such deferrals are limited to no longer than six
months.
SYSTEMATIC WITHDRAWAL PROGRAM

During the Accumulation Phase, you may elect to receive periodic income payments
under the systematic withdrawal program. Under the program, you may choose to
take monthly, quarterly, semi-annual or annual payments from your contract.
Electronic transfer of these funds to your bank account is also available. The
minimum amount of each withdrawal is $100. If you are an Oregon resident, the
minimum withdrawal amount is $100 per withdrawal or an amount equal to your free
withdrawal amount, as described on page 10. There must be at least $500
remaining in your contract at all times. Withdrawals may be taxable and a 10%
IRS penalty tax may apply if you are under age 59 1/2. There is no additional
charge for participating in this program, although a withdrawal charge and/or
MVA may apply.

The program is not available to everyone. Please check with our Annuity Service
Center, which can provide the necessary enrollment forms. We reserve the right
to modify, suspend or terminate this program at any time.

NURSING HOME WAIVER

If you are confined to a nursing home for 60 days or longer, we may waive the
withdrawal charge and/or market value adjustment on certain withdrawals prior to
the Annuity Date (not available in Texas). The waiver applies only to
withdrawals made while you are in a nursing home or within 90 days after you
leave the nursing home. Your contract prohibits use of this waiver during the
first 90 days after you purchase your contract. In addition, the confinement
period for which you seek the waiver must begin after you purchase your
contract.

In order to use this waiver, you must submit with your withdrawal request, the
following documents: (1) a doctor's note recommending admittance to a nursing
home; (2) an admittance form which shows the type of facility you entered; and
(3) a bill from the nursing home which shows that you met the 60 day confinement
requirement.

MINIMUM CONTRACT VALUE

Where permitted by state law, we may terminate your contract if both of the
following occur: (1) your contract is less than $500 as a result of withdrawals;
and (2) you have not made any Purchase Payments during the past three years. We
will provide you with sixty days written notice. At the end of the notice
period, we will distribute the contract's remaining value to you.

                                  DEATH BENEFIT
----------------------------------------------------------------
----------------------------------------------------------------

If you die during the Accumulation Phase of your contract, we pay a death
benefit to your Beneficiary. At the time you purchase your contract, you must
select one of the two death benefits described below. Once selected, you can not
change your death benefit option. You should discuss the available options with
your financial representative to determine which option is best for you.

                                       15
<PAGE>   22

OPTION 1 - PURCHASE PAYMENT ACCUMULATION OPTION

The death benefit is the greater of:

     1. the value of your contract at the time we receive satisfactory proof of
        death; or

     2. total Purchase Payments less withdrawals (and any fees or charges
        applicable to such withdrawals), compounded at a 4% annual growth rate
        until the date of death (3% growth rate if 70 or older at the time of
        contract issue) plus any Purchase Payments less withdrawals recorded
        after the date of death (and any fees or charges applicable to such
        withdrawals); or

     3. the value of your contract on the seventh contract anniversary, plus any
        Purchase Payments and less any withdrawals (and any fees or charges
        applicable to such withdrawals), since the seventh contract anniversary,
        all compounded at a 4% annual growth rate until the date of death (3%
        growth rate if age 70 or older at the time of contract issue) plus any
        Purchase Payments less withdrawals recorded after the date of death (and
        any fees or charges applicable to such withdrawals).

OPTION 2 - MAXIMUM ANNIVERSARY OPTION

The death benefit is the greater of:

     1. the value of your contract at the time we receive satisfactory proof of
        death; or

     2. total Purchase Payments less any withdrawals (and any fees or charges
        applicable to such withdrawals); or

     3. the maximum anniversary value on any contract anniversary prior to your
        81st birthday. The anniversary value equals the value of your contract
        on a contract anniversary plus any Purchase Payments and less any
        withdrawals (and any fees or charges applicable to such withdrawals),
        since that contract anniversary.

If you are age 90 or older at the time of death and selected the Option 2 death
benefit, the death benefit will be equal to the value of your contract at the
time we receive satisfactory proof of death. Accordingly, you do not get the
advantage of option 2 if:

     - you are over age 80 at the time of contract issue, or

     - you are 90 or older at the time of your death.

We will not pay a Deferred Payment Enhancement on a Purchase Payment if you die
before the corresponding Deferred Payment Enhancement Date. SEE PRINCIPAL
REWARDS PROGRAM ON PAGE 8.


We do not pay the death benefit if you die after you switch to the Income Phase.
However, if you die during the Income Phase, your Beneficiary receives any
remaining guaranteed income payments in accordance with the income option you
selected. SEE INCOME OPTIONS ON PAGE 18.


You name your Beneficiary. You may change the Beneficiary at any time, unless
you previously made an irrevocable Beneficiary designation.

We pay the death benefit when we receive satisfactory proof of death. We
consider the following satisfactory proof of death:

     1. a certified copy of the death certificate; or

     2. a certified copy of a decree of a court of competent jurisdiction as to
        the finding of death; or

     3. a written statement by a medical doctor who attended the deceased at the
        time of death; or

     4. any other proof satisfactory to us.

We may require additional proof before we pay the death benefit.

The death benefit payment must begin immediately upon receipt of all necessary
documents. In any event, the death benefit must be paid within 5 years of the
date of death unless the Beneficiary elects to have it payable in the form of an
income option. If the Beneficiary elects an income option, it must be paid over
the Beneficiary's lifetime or for a period not extending beyond the
Beneficiary's life expectancy. Payments must begin within one year of your
death.

If the Beneficiary is the spouse of a deceased owner, he or she can elect to
continue the Contract at the then current value. If the Beneficiary/spouse
continues the contract, we do not pay a death benefit to him or her.

If a Beneficiary does not elect a specific form of pay out within 60 days of our
receipt of proof of death, we pay a lump sum death benefit to the Beneficiary.

----------------------------------------------------------------
                                    EXPENSES
----------------------------------------------------------------
----------------------------------------------------------------

There are charges and expenses associated with your contract. These charges and
expenses reduce your investment return. We will not increase the contract
maintenance fee or the insurance and withdrawal charges under your contract.
However, the investment charges under your contract may increase or decrease.
Some states may require that we charge less than the amounts described below.

INSURANCE CHARGES

The amount of this charge is 1.52% annually, of the value of your contract
invested in the Variable Portfolios. We deduct the charge daily.

The insurance charge compensates us for the mortality and expense risks and the
costs of contract distribution assumed by Anchor National.

If these charges do not cover all of our expenses, we will pay the difference.
Likewise, if these charges exceed our expenses, we will keep the difference.

                                       16
<PAGE>   23

WITHDRAWAL CHARGES

The contract provides a free withdrawal amount every year. SEE ACCESS TO YOUR
MONEY, PAGE 14. If you take money out in excess of the free withdrawal amount,
and upon a full surrender, you may incur a withdrawal charge.

We apply a withdrawal charge against each Purchase Payment you put into the
contract. After a Purchase Payment has been in the contract for 7 complete
years, or 9 years if you elected to participate in the Principal Rewards
Program, no withdrawal charge applies. The withdrawal charge equals a percentage
of the Purchase Payment you take out of the contract. The withdrawal charge
percentage declines each year a Purchase Payment is in the contract. The two
withdrawal charge schedules are as follows:

</TABLE>

When calculating the withdrawal charge, we treat withdrawals as coming first
from the Purchase Payments that have been in your contract the longest. However,
for tax purposes, your withdrawals are considered earnings first, then Purchase
Payments.

Whenever possible, we deduct the withdrawal charge from the money remaining in
your contract. If you withdraw all of your contract value, we deduct any
applicable withdrawal charges from the amount withdrawn.


We will not assess a withdrawal charge for money withdrawn to pay a death
benefit or to pay contract fees or charges. We will not assess a withdrawal
charge when you switch to the Income Phase, except when you elect to receive
income payments using the Income Protector feature. If you elect to receive
income payments using the Income Protector feature, we assess the entire
withdrawal charge applicable to Purchase Payments remaining in your contract
when calculating your income benefit base. SEE INCOME OPTIONS ON PAGE 18.


Withdrawals made prior to age 59 1/2 may result in tax penalties. SEE, TAXES ON
PAGE 20.

INVESTMENT CHARGES

Charges are deducted from your Variable Portfolios for the advisory and other
expenses of the Variable Portfolios. THE FEE TABLES LOCATED AT PAGE 4 illustrate
these charges and expenses. For more detailed information on these investment
charges, refer to the prospectuses for the Trusts, enclosed or attached.

CONTRACT MAINTENANCE FEE

During the Accumulation Phase, we subtract a contract maintenance fee from your
account once per year. This charge compensates us for the cost of contract
administration. We deduct the $35 contract maintenance fee ($30 in North Dakota)
from your account value on your contract anniversary. If you withdraw your
entire contract value, we deduct the fee from that withdrawal.

If your contract value is $50,000 or more on your contract anniversary date, we
will waive the charge. This waiver is subject to change without notice.

TRANSFER FEE

We currently permit 15 free transfers between investment options each contract
year. We charge you $25 for each additional transfer that contract year ($10 in
Pennsylvania and Texas). SEE INVESTMENT OPTIONS ON PAGE 10.

PREMIUM TAX

Certain states charge the Company a tax on the premiums you pay into the
contract. We deduct from your contract these premium tax charges. Currently we
deduct the charge for premium taxes when you take a full withdrawal or begin the
Income Phase of the contract. In the future, we may assess this deduction at the
time you put Purchase Payment(s) into the contract or upon payment of a death
benefit.

APPENDIX D provides more information about premium taxes.

INCOME TAXES

We do not currently deduct income taxes from your contract. We reserve the right
to do so in the future.

REDUCTION OR ELIMINATION OF CHARGES AND EXPENSES, AND ADDITIONAL AMOUNTS
CREDITED

Sometimes sales of the contracts to groups of similarly situated individuals may
lower our administrative and/or sales expenses. We reserve the right to reduce
or waive certain charges and expenses when this type of sale occurs. In
addition, we may also credit additional interest to policies sold to such
groups. We determine which groups are eligible for such treatment. Some of the
criteria we evaluate to make a determination are: size of the group; amount of
expected Purchase Payments; relationship existing between us and prospective
purchaser; nature of the purchase; length of time a group of contracts is
expected to remain active; purpose of the purchase and whether that purpose
increases the likelihood that our expenses will be

                                       17
<PAGE>   24

reduced; and/or any other factors that we believe indicate that administrative
and/or sales expenses may be reduced.

Anchor National may make such a determination regarding sales to its employees,
it affiliates' employees and employees of currently contracted broker-dealers;
its registered representatives and immediate family members of all of those
described.

We reserve the right to change or modify any such determination or the treatment
applied to a particular group, at any time.

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

ANNUITY DATE

During the Income Phase, we use the money accumulated in your contract to make
regular income payments to you. You may switch to the Income Phase any time
after your 2nd contract anniversary. You select the month and year you want
income payments to begin. The first day of that month is the Annuity Date. You
may change your Annuity Date, so long as you do so at least seven days before
the income payments are scheduled to begin. Once you begin receiving income
payments, you cannot change your income option. Except as indicated under Option
5 below, once you begin receiving income payments, you cannot otherwise access
your money through a withdrawal or surrender.

If you switch to the Income Phase prior to a Deferred Payment Enhancement Date,
we will not allocate the corresponding Deferred Payment Enhancement to your
contract. SEE PRINCIPAL REWARDS PROGRAM ON PAGE 8.

Income payments must begin on or before your 90th birthday or on your tenth
contract anniversary, whichever occurs later. If you do not choose an Annuity
Date, your income payments will automatically begin on this date. Certain states
may require your income payments to start earlier.

If the Annuity Date is past your 85th birthday, your contract could lose its
status as an annuity under Federal tax laws. This may cause you to incur adverse
tax consequences.

In addition, most Qualified contracts require you to take minimum distributions
after you reach age 70 1/2. SEE TAXES ON PAGE 20.

INCOME OPTIONS

Currently, this Contract offers five income options. If you elect to receive
income payments but do not select an option, your income payments will be made
in accordance with option 4 for a period of 10 years. For income payments based
on joint lives, we pay according to option 3 for a period of 10 years.

We base our calculation of income payments on the life of the Annuitant and the
annuity rates set forth in your contract. As the contract owner, you may change
the Annuitant at any time prior to the Annuity Date. You must notify us if the
Annuitant dies before the Annuity Date and designate a new Annuitant.

     OPTION 1 - LIFE INCOME ANNUITY

This option provides income payments for the life of the Annuitant. Income
payments stop when the Annuitant dies.

     OPTION 2 - JOINT AND SURVIVOR LIFE ANNUITY

This option provides income payments for the life of the Annuitant and for the
life of another designated person. Upon the death of either person, we will
continue to make income payments during the lifetime of the survivor. Income
payments stop when the survivor dies.

     OPTION 3 - JOINT AND SURVIVOR LIFE ANNUITY WITH 10 OR 20 YEARS GUARANTEED

This option is similar to option 2 above, with an additional guarantee of
payments for at least 10 years. If the Annuitant and the survivor die before all
of the guaranteed income payments have been made, the remaining payments are
made to the Beneficiary under your contract.

     OPTION 4 - LIFE ANNUITY WITH 10 OR 20 YEARS GUARANTEED

This option is similar to option 1 above. In addition, this option provides a
guarantee that income payments will be made for at least 10 or 20 years. You
select the number of years. If the Annuitant dies before all guaranteed income
payments are made, the remaining income payments go to the Beneficiary under
your contract.

     OPTION 5 - INCOME FOR A SPECIFIED PERIOD

This option provides income payments for a guaranteed period ranging from 5 to
30 years. If the Annuitant dies before all the guaranteed income payments are
made, the remaining income payments are made to the Beneficiary under your
contract. Additionally, if variable income payments are elected under this
option, you (or the Beneficiary under the contract if the Annuitant dies prior
to all guaranteed income payments being made) may redeem any remaining
guaranteed variable income payments after the Annuity Date. The amount available
upon such redemption would be the discounted present value of any remaining
guaranteed variable income payments. If provided for in your contract, any
applicable withdrawal charge will be deducted from the discounted value as if
you fully surrendered your contract.

The value of an Annuity Unit, regardless of the option chosen, takes into
account the Mortality and Expense Risk Charge. Since Option 5 does not contain
an element of mortality risk, no benefit is derived from this charge.

Please read the Statement of Additional Information ("SAI") for a more detailed
discussion of the income options.

FIXED OR VARIABLE INCOME PAYMENTS

You can choose income payments that are fixed, variable or both. If at the date
when income payments begin you are

                                       18
<PAGE>   25

invested in the Variable Portfolios only, your income payments will be variable.
If your money is only in fixed accounts at that time, your income payments will
be fixed in amount. Further, if you are invested in both fixed and variable
investment options when income payments begin, your payments will be fixed and
variable. If income payments are fixed, Anchor National guarantees the amount of
each payment. If the income payments are variable the amount is not guaranteed.

INCOME PAYMENTS

We make income payments on a monthly, quarterly, semiannual or annual basis. You
instruct us to send you a check or to have the payments directly deposited into
your bank account. If state law allows, we distribute annuities with a contract
value of $5,000 or less in a lump sum. Also, if the selected income option
results in income payments of less than $50 per payment, we may decrease the
frequency of payments, state law allowing.

If you are invested in the Variable Portfolios after the Annuity date, your
income payments vary depending on four things:

     - for life options, your age when payments begin, and;

     - the value of your contract in the Variable Portfolios on the Annuity
       Date, and;

     - the 3.5% assumed investment rate used in the annuity table for the
       contract, and;

     - the performance of the Variable Portfolios in which you are invested
       during the time you receive income payments.

If you are invested in both the fixed account options and the Variable
Portfolios after the Annuity Date, the allocation of funds between the fixed and
variable options also impacts the amount of your annuity payments.

TRANSFERS DURING THE INCOME PHASE

During the Income Phase, one transfer per month is permitted between the
Variable Portfolios. No other transfers are allowed during the Income Phase.

DEFERMENT OF PAYMENTS

We may defer making fixed payments for up to six months, or less if required by
law. Interest is credited to you during the deferral period.

THE INCOME PROTECTOR FEATURE

The Income Protector feature is a future "safety net" which offers you the
ability to receive a guaranteed fixed minimum retirement income when you switch
to the Income Phase. With the Income Protector feature you know the level of
minimum income that will be available to you upon annuitization, regardless of
fluctuating market conditions.

The Income Protector is a standard feature of your contract, if available in
your state. There is no additional charge associated with this feature.

Other options were previously available under the Income Protector feature.
Generally, if you purchased your contract between November 2, 1998 and March 31,
1999 and the Income Protector feature was available in your state at that time,
the other provisions continue to apply to your contract. Please contact our
Annuity Service Center for more information.

We reserve the right to modify, suspend or terminate the Income Protector
feature at any time.

HOW WE DETERMINE THE AMOUNT OF YOUR MINIMUM GUARANTEED INCOME

We base the amount of minimum income available to you if you elect to receive
income payments using the Income Protector feature upon a calculation we call
the income benefit base.

The income benefit base is only a calculation. It does not represent a contract
value, nor does it guarantee performance of the Variable Portfolios in which you
invest.

Your income benefit base increases if you make subsequent Purchase Payments and
decreases if you withdraw money from your contract. The exact income benefit
base calculation is equal to (a) plus (b) minus (c) where:

     (a) is equal to, for the first year of calculation, your initial Purchase
         Payment, or for each subsequent year of calculation, the income benefit
         base on the prior contract anniversary, and;

     (b) is equal to the sum of all subsequent Purchase Payments made into the
         contract since the last contract anniversary, and;

     (c) is equal to all withdrawals and applicable fees and charges since the
         last contract anniversary, in an amount proportionate to the amount by
         which such withdrawals decreased your contract value.

ELECTING TO RECEIVE INCOME PAYMENTS

You may elect to begin the Income Phase of your contract using the Income
Protector feature ONLY within the 30 days after the seventh or later contract
anniversary.

The contract anniversary prior to your election to begin receiving income
payments is your income benefit date. This is the date as of which we calculate
your income benefit base to use in determining your guaranteed minimum fixed
retirement income. Your final income benefit base is equal to (a) minus (b)
where:

     (a) is equal to your income benefit base as of your income benefit date,
         and;

     (b) is equal to any partial withdrawals of contract value and any charges
         applicable to those withdrawals and any withdrawal charges otherwise
         applicable,

                                       19
<PAGE>   26

         calculated as if you fully surrender your contract as the income
         benefit date, and any applicable premium taxes.

To arrive at the minimum guaranteed retirement income available to you we apply
to your final income benefit base to the annuity rates stated in your Income
Protector endorsement for the income option you select. You then choose if you
would like to receive that income annually, semi-annually quarterly or monthly
for the time guaranteed under your selected income option. The income options
available when using the income protector feature to receive your retirement
income are:

     - Life Annuity with 10 Years Guaranteed, or

     - Joint and Survivor Life Annuity with 20 Years Guaranteed

At the time you elect to begin receiving income payments, we will calculate your
income payments using both your income benefit base and your contract value. We
will use the same income option for each calculation, however, the annuity
factors used to calculate your income under the Income Protector feature will be
different. You will receive whichever provides a greater stream of income. If
you elect to receive income payments using the Income Protector feature your
income payments will be fixed in amount. You are not required to use the Income
Protector feature to receive income payments.

NOTE TO QUALIFIED CONTRACT HOLDERS

Qualified contracts generally require that you select an income option which
does not exceed your life expectancy. That restriction, if it applies to you,
may limit your ability to use the Income Protector feature.

You may wish to consult your tax advisor for information concerning your
particular circumstances.

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

NOTE: WE PREPARED THE FOLLOWING INFORMATION ON TAXES AS A GENERAL DISCUSSION OF
THE SUBJECT. IT IS NOT TAX ADVICE. WE CAUTION YOU TO SEEK COMPETENT TAX ADVICE
ABOUT YOUR OWN CIRCUMSTANCES. WE DO NOT GUARANTEE THE TAX STATUS OF YOUR
ANNUITY. TAX LAWS CONSTANTLY CHANGE, THEREFORE WE CANNOT GUARANTEE THAT THE
INFORMATION CONTAINED HEREIN IS COMPLETE AND/OR ACCURATE.

ANNUITY CONTRACTS IN GENERAL

The Internal Revenue Code ("IRC") provides for special rules regarding the tax
treatment of annuity contracts. Generally, taxes on the earnings in your annuity
contract are deferred until you take the money out. Qualified retirement
investments automatically provide tax deferral regardless of whether the
underlying contract is an annuity. Different rules apply depending on how you
take the money out and whether your contract is Qualified or Non-qualified.

If you do not purchase your contract under a pension plan, a specially sponsored
employer program or an individual retirement account, your contract is referred
to as a Non-qualified contract. A Non-qualified contract receives different tax
treatment than a Qualified contract. In general, your cost basis in a
Non-qualified contract is equal to the Purchase Payments you put into the
contract. You have already been taxed on the cost basis in your contract.

If you purchase your contract under a pension plan, a specially sponsored
employer program or as an individual retirement account, your contract is
referred to as a Qualified contract. Examples of qualified plans are: Individual
Retirement Accounts ("IRAs"), Roth IRAs, Tax-Sheltered

                                       20
<PAGE>   27

Annuities (referred to as 403(b) contracts), H.R. 10 Plans (referred to as Keogh
Plans) and pension and profit sharing plans, including 401(k) plans. Typically
you have not paid any tax on the Purchase Payments used to buy your contract and
therefore, you have no cost basis in your contract.

TAX TREATMENT OF DISTRIBUTIONS -
NON-QUALIFIED CONTRACTS

If you make a withdrawal from a Non-qualified contract, the IRC treats such a
withdrawal as first coming from the earnings and then as coming from your
Purchase Payments. For income payments, any portion of each payment that is
considered a return of your Purchase Payment will not be taxed. Withdrawn
earnings are treated as income to you and are taxable. The IRC provides for a
10% penalty tax on any earnings that are withdrawn other than in conjunction
with the following circumstances: (1) after reaching age 59 1/2; (2) when paid
to your Beneficiary after you die; (3) after you become disabled (as defined in
the IRC); (4) when paid in a series of substantially equal installments made for
your life or for the joint lives of you and you Beneficiary; (5) under an
immediate annuity; or (6) which come from Purchase Payments made prior to August
14, 1982.

TAX TREATMENT OF DISTRIBUTIONS - QUALIFIED CONTRACTS

Generally, you have not paid any taxes on the Purchase Payments used to buy a
Qualified contract. Any amount of money you take out as a withdrawal or as
income payments is taxable income. The IRC further provides for a 10% penalty
tax on any withdrawal or income payment paid to you other than in conjunction
with the following circumstances: (1) after reaching age 59 1/2; (2) when paid
to your Beneficiary after you die; (3) after you become disabled (as defined in
the IRC); (4) in a series of substantially equal installments made for your life
or for the joint lives of you and your Beneficiary; (5) to the extent such
withdrawals do not exceed limitations set by the IRC for amounts paid during the
taxable year for medical care; (6) to fund higher education expenses (as defined
in IRC); (7) to fund certain first-time home purchase expenses; and, except in
the case of an IRA; (8) when you separate from service after attaining age 55;
and (9) when paid to an alternate payee pursuant to a qualified domestic
relations order.

The IRC limits the withdrawal of Purchase Payments from certain Tax-Sheltered
Annuities. Withdrawals can only be made when an owner: (1) reaches age 59 1/2;
(2) leaves his or her job; (3) dies; (4) becomes disabled (as defined in the
IRC); or (5) experiences a hardship (as defined in the IRC). In the case of
hardship, the owner can only withdraw Purchase Payments.

MINIMUM DISTRIBUTIONS

Generally, the IRS requires that you begin taking annual distributions from
qualified annuity contracts by April 1 of the calendar year following the later
of (1) the calendar year in which you attain age 70 1/2 or (2) the calendar year
in which you retire.

We currently waive surrender charges and MVA on withdrawals taken to meet
minimum distribution requirements. Current operational practice is to provide a
free withdrawal of the greater of the contract's maximum penalty free amount or
the required minimum distribution amount for a particular contract (but not
both).

Failure to satisfy the minimum distribution requirements may result in a tax
penalty. You should consult your tax advisor for more information.

DIVERSIFICATION

The IRC imposes certain diversification requirements on the underlying
investments for a variable annuity. We believe that each underlying Variable
Portfolios' management monitors the Variable Portfolios so as to comply with
these requirements. To be treated as a variable annuity for tax purposes, the
underlying investments must meet these requirements.

The diversification regulations do not provide guidance as to the circumstances
under which you, because of the degree of control you exercise over the
underlying investments, and not Anchor National, would be considered the owner
of the shares of the Variable Portfolios. It is unknown to what extent owners
are permitted to select investments, to make transfers among Variable Portfolios
or the number and type of Variable Portfolios owners may select from. If any
guidance is provided which is considered a new position, then the guidance would
generally be applied prospectively. However, if such guidance is considered not
to be a new position, it may be applied retroactively. This would mean you, as
the owner of the contract, could be treated as the owner of the underlying
Variable Portfolios. Due to the uncertainty in this area, we reserve the right
to modify the contract in an attempt to maintain favorable tax treatment.

----------------------------------------------------------------
----------------------------------------------------------------
                                   PERFORMANCE
----------------------------------------------------------------
----------------------------------------------------------------

We advertise the Cash Management Portfolio's yield and effective yield. In
addition, the other Variable Portfolios advertise total return, gross yield and
yield-to-maturity. These figures represent past performance of the Variable
Portfolios. These performance numbers do not indicate future results.

When we advertise performance for periods prior to the date the contracts were
first issued, we derive the figures from the performance of the corresponding
portfolios for the Trusts, if available. We modify these numbers to reflect
charges and expenses as if the contract was in existence during the period
stated in the advertisement. Figures calculated in this manner do not represent
actual historic performance of the particular Variable Portfolio.

                                       21
<PAGE>   28

Consult the SAI for more detailed information regarding the calculation of
performance data. The performance of each Variable Portfolio may also be
measured against unmanaged market indices. The indices we use include but are
not limited to the Dow Jones Industrial Average, the Standard & Poor's 500, the
Russell 1000 Growth Index, the Morgan Stanley Capital International Europe,
Australia and Far East Index ("EAFE") and the Morgan Stanley Capital
International World Index. We may compare the Variable Portfolios' performance
to that of other variable annuities with similar objectives and policies as
reported by independent ranking agencies such as Morningstar, Inc., Lipper
Analytical Services, Inc. or Variable Annuity Research & Data Service ("VARDS").

Anchor National may also advertise the rating and other information assigned to
it by independent industry ratings organizations. Some of those organizations
are A.M. Best Company ("A.M. Best"), Moody's Investor's Service ("Moody's"),
Standard & Poor's Insurance Rating Services ("S&P"), and Duff & Phelps. A.M.
Best's and Moody's ratings reflect their current opinion of our financial
strength and performance in comparison to others in the life and health
insurance industry. S&P's and Duff & Phelps' ratings measure the ability of an
insurance company to meet its obligations under insurance policies it issues.
These two ratings do not measure the insurer's ability to meet non-policy
obligations. Ratings in general do not relate to the performance of the Variable
Portfolios.

                                OTHER INFORMATION
----------------------------------------------------------------
----------------------------------------------------------------

ANCHOR NATIONAL

Anchor National is a stock life insurance company originally organized under the
laws of the state of California in April 1965. On January 1, 1996, Anchor
National redomesticated under the laws of the state of Arizona.

Anchor National and its affiliates, SunAmerica Life Insurance Company, First
SunAmerica Life Insurance Company, CalAmerica Life Insurance Company, SunAmerica
National Life Insurance Company, SunAmerica Asset Management Corp., Resources
Trust Company, and the SunAmerica Financial Network, Inc. broker-dealers,
specialize in retirement savings and investment products and services. Business
focuses include fixed and variable annuities, mutual funds, broker-dealer
services and trust administration services.

THE SEPARATE ACCOUNT

Anchor National established Variable Separate Account ("separate account"),
under Arizona law on January 1, 1996 when it assumed the separate account,
originally established under California law on June 25, 1981. The separate
account is registered with the SEC as a unit investment trust under the
Investment Company Act of 1940, as amended.

Anchor National owns the assets in the separate account. However, the assets in
the separate account are not chargeable with liabilities arising out of any
other business conducted by Anchor National. Income gains and losses (realized
and unrealized) resulting from assets in the separate account are credited to or
charged against the separate account without regard to other income gains or
losses of Anchor National.

THE GENERAL ACCOUNT

Money allocated to the fixed account options goes into Anchor National's general
account. The general account consists of all of Anchor National's assets other
than assets attributable to a separate account. All of the assets in the general
account are chargeable with the claims of any Anchor National contract holders
as well as all of its creditors. The general account funds are invested as
permitted under state insurance laws.

DISTRIBUTION OF THE CONTRACT


Registered representatives of broker-dealers sell the contract. We pay
commissions to these representatives for the sale of the contracts. We do not
expect the total commissions to exceed 7% of your Purchase Payments. Contracts
sold with the Principal Rewards program may result in our paying lower
commission. We may also pay a bonus to representatives for contracts which stay
active for a particular period of time, in addition to standard commissions. We
do not deduct commissions paid to registered representatives directly from your
Purchase Payments.


From time to time, we may pay or allow additional promotional incentives in the
form of cash or other compensation. We reserve the right to offer these
additional incentives only to certain broker-dealers that sell or are expected
to sell, certain minimum amounts of the contract, or other contracts offered by
us. Promotional incentives may change at any time.

SunAmerica Capital Services, Inc., 733 Third Avenue, 4th Floor, New York, New
York 10017 distributes the contracts. SunAmerica Capital Services, an affiliate
of Anchor National, is registered as a broker-dealer under the Exchange Act of
1934 and is a member of the National Association of Securities Dealers, Inc. No
underwriting fees are paid in connection with the distribution of the contracts.

ADMINISTRATION

We are responsible for the administrative servicing of your contract. Please
contact our Annuity Service Center
at 1-800-445-SUN2, if you have any comment, question or service request.

                                       22
<PAGE>   29

We send out transaction confirmations and quarterly statements. During the
accumulation phase, you will receive confirmation of transactions within your
contract. Transactions made pursuant to contractual or systematic agreements,
such as deduction of the annual maintenance fee and dollar cost averaging, may
be confirmed quarterly. Purchase payments received through the automatic payment
plan or a salary reduction arrangement, may also be confirmed quarterly. For all
other transactions, we send confirmations immediately. It is your responsibility
to review these documents carefully and notify us of any inaccuracies
immediately. We investigate all inquiries. To the extent that we believe we made
an error, we retroactively adjust your contract, provided you notify us within
30 days of receiving the transaction confirmation or quarterly statement. Any
other adjustments we deem warranted are made as of the time we receive notice of
the error.

YEAR 2000

The Year 2000 issue arose from computer programs written using two digits rather
than four digits to define the applicable year. This possibly could have caused
a failure of the information technology systems (IT systems) and other equipment
containing imbedded technology (non-IT systems) in the year 2000. The Company
implemented a plan to address the Year 2000 issue and to assess Year 2000 issues
relating to third parties with which the Company has critical relationships. The
Company's cost to make necessary repairs had no significant impact on its
results of operations. The Company has not experienced any business disruption
from the Year 2000 issue. Its IT and non-IT systems were compliant on January 1,
2000, and there have been no problems related to any third parties compliance.

LEGAL PROCEEDINGS

There are no pending legal proceedings affecting the separate account. Anchor
National and its subsidiaries engage in various kinds of routine litigation. In
management's opinion, these matters are not of material importance to their
respective total assets nor are they material with respect to the separate
account.

OWNERSHIP

The PolarisII Variable Annuity is a Flexible Payment Group Deferred Annuity
contract. We issue a group contract to a contract holder for the benefit of the
participants in the group. As a participant in the group, you will receive a
certificate which evidences your ownership. As used in this prospectus, the term
contract refers to your certificate. In some states, a Flexible Payment
Individual Modified Guaranteed and Variable Deferred Annuity contract is
available instead. Such a contract is identical to the contract described in
this prospectus, with the exception that we issue it directly to the owner.

CUSTODIAN

State Street Bank and Trust Company, 255 Franklin Street, Boston, Massachusetts
02110, serves as the custodian of the assets of the separate account. Anchor
National pays State Street Bank for services provided, based on a schedule of
fees.

INDEPENDENT ACCOUNTANTS

The audited consolidated financial statements of Anchor National as of December
31, 1999, December 31, 1998 and September 30, 1998 and for the year ended
December 31, 1999, for the three months ended December 31, 1998 and for each of
the two fiscal years in the period ended September 30, 1998 incorporated by
reference in this prospectus have been so included in reliance on the report of
PricewaterhouseCoopers LLP, independent accountants, given on the authority of
said firm as experts in auditing and accounting.

REGISTRATION STATEMENT

A registration statement has been filed with the SEC under the Securities Act of
1933 relating to the contract. This prospectus does not contain all the
information in the registration statement as permitted by SEC regulations. The
omitted information can be obtained from the SEC's principal office in
Washington, D.C., upon payment of a prescribed fee.

                APPENDIX B -- PRINCIPAL REWARDS PROGRAM EXAMPLES
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------

I.  DEFERRED PAYMENT ENHANCEMENT

If you elect to participate in the Principal Rewards Program at contract issue,
we contribute at least 2% of each Purchase Payment to your contract for each
Purchase Payment we receive as an Upfront Payment Enhancement. Any applicable
Deferred Payment Enhancement is allocated to your contract on the corresponding
Deferred Payment Enhancement Date and, if declared by the Company, is a
percentage of your remaining Purchase Payment on the Deferred Payment
Enhancement Date. Deferred Purchase Payment Enhancements are reduced
proportionately by partial withdrawals of that Purchase Payment prior to the
Deferred Payment Enhancement Date.

The examples that follow assume an initial Purchase Payment of $125,000 and that
the Deferred Payment Enhancement is 1%.

For purposes of the example, the Deferred Payment Enhancement Date is the 9th
anniversary of the Purchase Payment.

EXAMPLE 1 - NO WITHDRAWALS ARE MADE

The Upfront Payment Enhancement allocated to your contract is $2,500 (2% of
$125,000).

On your 9th contract anniversary, the Deferred Payment Enhancement Date, your
Deferred Payment Enhancement of $1,250 (1% of your remaining Purchase Payment or
$125,000) will be allocated to your contract.

EXAMPLE 2 - WITHDRAWAL MADE PRIOR TO DEFERRED PAYMENT ENHANCEMENT DATE

As in Example 1, your Upfront Payment Enhancement is $2,500.

This example also assumes the following:

     1. Your contract value on your 5th contract anniversary is $190,000.

     2. You request a withdrawal of $75,000 on your 5th contract anniversary.

     3. No subsequent Purchase Payments have been made.

     4. No prior withdrawals have been taken.

     5. Funds are not allocated to any of the MVA Fixed Accounts.

On your 5th contract anniversary, your penalty-free earnings in the contract are
$65,000 ($190,000 contract value less your $125,000 investment in the contract).
Therefore, you are withdrawing $10,000 of your initial Purchase Payment. Your
contract value will also be reduced by a $500 withdrawal charge on the $10,000
Purchase Payment (5% of $10,000). Your gross withdrawal is $75,500 of which
$10,500 constitutes part of your Purchase Payment.

The withdrawal of $10,500 of your $125,000 Purchase Payment is a withdrawal of
8.4% of your Purchase Payment. Therefore, only 91.6%, or $114,500, of your
initial Purchase Payment remains in your contract.

On your 9th contract anniversary, the Deferred Payment Enhancement Date,
assuming no other transactions occur affecting the Purchase Payment, we allocate
your Deferred Payment Enhancement of $1,145 (1% of your remaining Purchase
Payment, $114,500) to your contract.

II.  90 DAY WINDOW

Contracts issued with the Principal Rewards feature after April 3, 2000, may be
eligible for a "Look-Back Adjustment." As of the 90th day after your contract
was issued, we will total your Purchase Payments remaining in your contract at
that time, without considering any investment gain or loss in contract value on
those Purchase Payments. If your total Purchase Payments bring you to an
Enhancement Level which, as of the date we issued your contract, would have
provided for a higher Upfront and/or Deferred Payment Enhancement Rate on each
Purchase Payment, you will get the benefit of the Enhancement Rate(s) that were
applicable to that higher Enhancement Level at the time your contract was
issued.

This example assumes the following:


1. Current Enhancement Levels, Rates and Dates (beginning July 5, 2000)
   throughout the first 90 days.


2. No withdrawal in the first 90 days.


3. Initial Purchase Payment of $35,000 on July 5, 2000.



4. Subsequent Purchase Payment of $40,000 on August 15, 2000.



5. Subsequent Purchase Payment of $25,000 on August 30, 2000.



6. Subsequent Purchase Payment of $7,500 on September 12, 2000.

</TABLE>


ENHANCEMENT ADJUSTMENTS ON THE 90TH DAY FOLLOWING CONTRACT ISSUE

The sum of all Purchase Payments made in the first 90 days of the contract
equals $107,500. According to the Enhancement Levels in effect at the time this
contract was issued, a $107,500 Purchase Payment would have received a 4%
Upfront Payment Enhancement and a 1% Deferred Payment Enhancement. Under the 90
Day Window provision all Purchase Payments made within those first 90 days would
receive the benefit of the parameters in place at the time the contract was
issued, as if all of the Purchase Payments were received on the date of issue.
Thus, the first two Purchase Payments would be adjusted as follows:

                  APPENDIX C - MARKET VALUE ADJUSTMENT ("MVA")
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------

The MVA reflects the impact that changing interest rates have on the value of
money invested at a fixed interest rate. The longer the period of time remaining
in the term you initially agreed to leave your money in the fixed account
option, the greater the impact of changing interest rates. The impact of the MVA
can be either positive or negative, and is computed by multiplying the amount
withdrawn, transferred or switched to the Income Phase by the following factor:

                           [(1+I/(1+J+0.005)]N/12 - 1

                  The MVA formula may differ in certain states
  where:

        I is the interest rate you are earning on the money invested in the
        fixed account option;

        J is the interest rate then currently available for the period of time
        equal to the number of years remaining in the term you initially agreed
        to leave your money in the fixed account option; and

        N is the number of full months remaining in the term you initially
        agreed to leave your money in the fixed account option.

EXAMPLES OF THE MVA

The examples below assume the following:

     (1) You made an initial Purchase Payment of $10,000 and allocated it to the
         10-year fixed account option at a rate of 5%;

     (2) You make a partial withdrawal of $4,000 when 1 year (12 months) remains
         in the 10-year term you initially agreed to leave your money in the
         fixed account option (N=12); and

     (3) You have not made any other transfers, additional Purchase Payments, or
         withdrawals.

No withdrawal charges are reflected because your Purchase Payment has been in
the contract for nine full years. If a withdrawal charge applies, it is deducted
before the MVA. The MVA is assessed on the amount withdrawn less any withdrawal
charges.

POSITIVE ADJUSTMENT

Assume that on the date of withdrawal, the interest rate in effect for a new
Purchase Payments in the 1-year fixed account option is 4%.

The MVA factor is = [(1+I/(1+J+0.005)]N/12 - 1
                  = [(1.05)/(1.04+0.005)]12/12 - 1
                  = (1.004785)1 - 1
                  = 1.004785 - 1
                  = + 0.004785

The requested withdrawal amount is multiplied by the MVA factor to determine the
MVA:
                         $4,000 x (+0.004785) = +$19.14

$19.14 represents the MVA that would be added to your withdrawal.

NEGATIVE ADJUSTMENT

Assume that on the date of withdrawal, the interest rate in effect for new
Purchase Payments in the 1-year fixed account option is 6%.

The MVA factor is = [(1+I)/(1+J+0.005)]N/12 - 1
                  = [(1.05)/(1.06+0.005)]12/12 - 1
                  = (0.985915)1 - 1
                  = 0.985915 - 1
                  = - 0.014085

The requested withdrawal amount is multiplied by the MVA factor to determine the
MVA:
                         $4,000 X (-0.014085) = -$56.34

$56.34 represents the MVA that will be deducted from the money remaining in the
10-year fixed account option.

                              [POLARIS II PROFILE LOGO]


THIS PROFILE IS A SUMMARY OF SOME OF THE MORE IMPORTANT POINTS THAT YOU SHOULD
KNOW AND CONSIDER BEFORE PURCHASING THE POLARIS(II) VARIABLE ANNUITY. THE
ANNUITY IS MORE FULLY DESCRIBED IN THE PROSPECTUS. PLEASE READ THE PROSPECTUS
CAREFULLY.

                                  July 5, 2000


----------------------------------------------------------------
----------------------------------------------------------------
                      1. THE POLARIS(II) VARIABLE ANNUITY
----------------------------------------------------------------
----------------------------------------------------------------

The Polaris(II) Variable Annuity is a contract between you and Anchor National
Life Insurance Company. It is designed to help you invest on a tax-deferred
basis and meet long-term financial goals, such as retirement funding. Tax
deferral means all your money, including the amount you would otherwise pay in
current income taxes, remains in your contract to generate more earnings. Your
money could grow faster than it would in a comparable taxable investment.


Polaris(II) offers a diverse selection of money managers and investment options.
You may divide your money among any or all 31 variable portfolios and 7 fixed
account options. To the extent you invest in the variable portfolios, your
investment is not guaranteed. The value of your Polaris(II) contract can
fluctuate up and down, based on the performance of the underlying investments
you select and you may experience a loss.


The variable portfolios offer professionally managed investment choices with
goals ranging from capital preservation to aggressive growth. Your choices for
the various investment options are found on the next page.

The contract also offers 7 fixed account options, for different time periods.
Each may have a different interest rate. Interest rates are guaranteed by Anchor
National.

Like most annuities, the contract has an accumulation phase and an income phase.
During the accumulation phase, you invest money in your contract. Your earnings
are based on the investment performance of the variable portfolios to which your
money is allocated and/or the interest rate(s) earned on the fixed account
option(s) in which you invest. You may withdraw money from your contract during
the accumulation phase. However, as with other tax-deferred investments, you
will pay taxes on earnings and untaxed contributions when you withdraw them. A
federal tax penalty may apply if you make withdrawals before age 59 1/2.

During the income phase, you may receive income payments from your annuity. Your
income payments may be fixed in dollar amount, vary with investment performance
or a combination of both, depending on where your money is allocated. Among
other factors, the amount of money you are able to accumulate in your contract
during the accumulation phase will affect the amount of your income payments
during the income phase.
----------------------------------------------------------------
----------------------------------------------------------------
                               2. INCOME OPTIONS
----------------------------------------------------------------
----------------------------------------------------------------

You can select from one of five income options:

   (1) payments for your lifetime;

   (2) payments for your lifetime and your survivor's lifetime;

   (3) payments for your lifetime and your survivor's lifetime, but for not less
       than 10 or 20 years;

   (4) payments for your lifetime, but for not less than 10 or 20 years; and

   (5) payments for a specified period of 5 to 30 years.

You will also need to decide when your income payments begin and if you want
your income payments to fluctuate with investment performance or remain
constant. Once you begin receiving income payments, you cannot change your
income option.

If your contract is part of a non-qualified retirement plan (one that is
established with after-tax dollars), payments during the income phase are
considered partly a return of your original investment. The "original
investment" part of each payment is not taxable as income. For contracts which
are part of a qualified retirement plan using before-tax dollars, the entire
income payment is taxable as income.

In addition to the above income options, you may elect to take income payments
under the income protector feature, subject to the provisions thereof.

                      3. PURCHASING A POLARIS(II) VARIABLE
                                ANNUITY CONTRACT
----------------------------------------------------------------
----------------------------------------------------------------

You can buy a contract through your financial representative, who can also help
you complete the proper forms. For non-qualified contracts, the minimum initial
purchase payment is $5,000 and subsequent amounts of $500 or more may be added
to your contract at any time during the accumulation phase. For qualified
contracts, the minimum initial purchase payment is $2,000 and subsequent amounts
of $250 or more may be added to your contract at any time during the
accumulation phase.

You may also allocate money to the 1-year fixed account option or the 3, 5, 7
and 10-year market value adjustment ("MVA") fixed account options and, under
certain circumstances, the 6-month and 1-year Dollar Cost Averaging ("DCA")
fixed account options.

The interest rates applicable for these fixed account options may differ from
time to time, however, we will never credit less than a 3% annual effective
rate. Once established, the rate will not change during the selected period.
Your contract value will be adjusted up or down for withdrawals or transfers
from the 3, 5, 7 and 10-year fixed account options prior to the end of the
guarantee period.

                ----------------------------------------------------------------
                ----------------------------------------------------------------
                                  5. EXPENSES
                ----------------------------------------------------------------
                ----------------------------------------------------------------

Each year, we deduct a $35 contract maintenance fee ($30 in North Dakota) from
your contract. We also deduct insurance charges which equal 1.52% annually of
the average daily value of your contract allocated to the variable portfolios.

As with other professionally managed investments, there are investment charges
imposed on contracts with money allocated to the variable portfolios. We
estimate these fees to range from .53 to 1.90.

If you take money out of your contract, you may be assessed a withdrawal charge
which is a percentage of the money you withdraw. The percentage declines over
the time the money is in the contract.

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

Each year, you are allowed to make 15 transfers without charge. After your first
15 free transfers, a $25 transfer fee ($10 in Pennsylvania and Texas) applies to
each subsequent transfer.

In a limited number of states, you may also be charged for a state premium tax
of up to 3.5% depending upon the state.

The following chart is designed to help you understand the charges in your
contract. The column "Total Annual Charges" shows the total of the 1.52%
insurance charges, the $35 contract maintenance fee and the investment charges
for each variable portfolio. We converted the contract maintenance fee to a
percentage using an assumed contract size of $40,000. The actual impact of this
charge on your contract may differ from this percentage.

The next two columns show two examples of the charges you would pay under the
contract. The examples assume that you invested $1,000 in a contract which earns
5% annually and that you withdraw your money: (1) at the end of year 1, and (2)
at the end of year 10. The premium tax is assumed to be 0% in both examples.

                                    6. TAXES
                ----------------------------------------------------------------
                ----------------------------------------------------------------

Unlike taxable investments where earnings are taxed in the year they are earned,
taxes on amounts earned in a non-qualified contract are deferred until they are
withdrawn. In a qualified contract, all amounts are taxable when they are
withdrawn.

When you begin taking distributions or withdrawals from your contract, earnings
are considered to be taken out first and will be taxed at your ordinary income
rate. You may be subject to a 10% federal tax penalty for distributions or
withdrawals before age 59 1/2.

                ----------------------------------------------------------------
                ----------------------------------------------------------------
                            7. ACCESS TO YOUR MONEY
                ----------------------------------------------------------------
                ----------------------------------------------------------------

During the first year, you may withdraw free of a withdrawal charge an amount
that is equal to the penalty-free earnings in your contract as of the date you
make the withdrawal or, if you participate in the systematic withdrawal program,
you may withdraw 10% of your total invested amount less any withdrawals made
during the year. The penalty-free earnings amount is calculated by taking the
value of your contract on the day you make the withdrawal and subtracting your
total invested amount. After the first year, your maximum free withdrawal amount
is the greater of: (1) the penalty-free earnings or (2) 10% of your total
invested amount that has been invested for at least one year, less any
withdrawals made during the year. Withdrawals in excess of these limits will be
assessed a withdrawal charge.

If you withdraw your entire contract value, you will not receive the benefit of
any free withdrawal amount. After your money has been in the contract for seven
full years, there are no withdrawal charges on that portion of the money that
you have invested for at least seven full years.

When you invest in the PolarisII Variable Annuity, your money is actually
invested in the underlying portfolios of the Anchor Series Trust and/or the
SunAmerica Series Trust. The value of your annuity will fluctuate depending upon
the investment performance of the portfolio(s) you choose.

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

If you should die during the accumulation phase, your beneficiary will receive a
death benefit. You must select from the two death benefit options described
below at the time you purchase your contract. Once selected, your death benefit
may not be changed. You should discuss with your financial representative the
options available to you and which option is best for you.

     OPTION 1 - PURCHASE PAYMENT ACCUMULATION OPTION:

The death benefit is the greater of:

(1) the value of your contract at the time we receive satisfactory proof of
    death; or

(2) total purchase payments less withdrawals (and any fees or charges applicable
    to such withdrawals), compounded at a 4% annual growth rate until the date
    of death (3% growth rate if 70 or older at the time of contract issue) plus
    any purchase payments less withdrawals recorded after the date of death (and
    any fees or charges applicable to such withdrawals); or

(3) the value of your contract on the seventh contract anniversary, plus any
    purchase payments since the seventh anniversary and less any withdrawals
    (and any fees or charges applicable to such withdrawals), all compounded at
    a 4% annual growth rate until the date of death (3% if 70 or older at the
    time of contract issue) plus any purchase payments less withdrawals recorded
    after the date of death (and any fees or charges applicable to such
    withdrawals).

     OPTION 2 - MAXIMUM ANNIVERSARY OPTION:

The death benefit is the greater of:

(1) the value of your contract at the time we receive satisfactory proof of
    death; or

(2) total purchase payments less any withdrawals (and any fees or charges
    applicable to such withdrawals); or

(3) the maximum anniversary value on any contract anniversary prior to your 81st
    birthday. The anniversary value equals the value of your contract on a
    contract anniversary plus any purchase payments and less any withdrawals
    (and any fees or charges applicable to such withdrawals) since that
    anniversary.

If you are age 90 or older at the time of death and selected the option 2 death
benefit, the death benefit will be equal to the value of your contract at the
time we receive satisfactory proof of death.

                ----------------------------------------------------------------
                             10. OTHER INFORMATION
                ----------------------------------------------------------------
                ----------------------------------------------------------------

FREE LOOK: You may cancel your contract within ten days (or longer if required
by your state) by mailing it to our Annuity Service Center. Your contract will
be treated as void on the date we receive it and we will pay you an amount equal
to the value of your contract (unless otherwise required by state law). Its
value may be more or less than the money you initially invested.

ASSET ALLOCATION REBALANCING: If selected by you, this program seeks to keep
your investment in line with your goals. We will maintain your specified
allocation mix in the variable portfolios and the 1-year fixed account option by
readjusting your money on a calendar quarter, semiannual or annual basis.

SYSTEMATIC WITHDRAWAL PROGRAM: If selected by you, this program allows you to
receive either monthly, quarterly, semiannual or annual checks during the
accumulation phase. Systematic withdrawals may also be electronically
transferred to your bank account. Of course, withdrawals may be taxable and a
10% federal tax penalty may apply if you are under age 59 1/2.
<PAGE>   41

PRINCIPAL ADVANTAGE PROGRAM: If selected by you, this program allows you to
obtain growth potential without any market risk to your principal. We will
guarantee that the portion of your money allocated to the 1, 3, 5, 7 or 10-year
fixed account option will grow to equal your principal investment when it is
allocated in accordance with the program.


DOLLAR COST AVERAGING: If selected by you, this program allows you to invest
gradually in the variable portfolios from any of the variable portfolios, the
1-year fixed account option, the 6-month DCA fixed account option or the 1-year
DCA fixed account option.


AUTOMATIC PAYMENT PLAN: You can add to your contract directly from your bank
account with as little as $20 per month.

CONFIRMATIONS AND QUARTERLY STATEMENTS: During the accumulation phase, you will
receive confirmation of transactions within your contract. Transactions made
pursuant to contractual or systematic agreements, such as deduction of the
annual maintenance fee and dollar cost averaging, may be confirmed quarterly.
Purchase payments received through the automatic payment plan or a salary
reduction arrangement, may also be confirmed quarterly. For all other
transactions, we send confirmations immediately.

During the accumulation and income phases, you will receive a statement of your
transactions over the past quarter and a summary of your account values.

         SECURITIES AND EXCHANGE COMMISSION POSITION ON INDEMNIFICATION
----------------------------------------------------------------
----------------------------------------------------------------

Indemnification for liabilities arising under the Securities Act of 1933 (the
"Act") is provided to Anchor National's officers, directors and controlling
persons. The SEC has advised that it believes such indemnification is against
public policy under the Act and unenforceable. If a claim for indemnification
against such liabilities (other than for Anchor National's payment of expenses
incurred or paid by its directors, officers or controlling persons in the
successful defense of any legal action) is asserted by a director, officer or
controlling person of Anchor National in connection with the securities
registered under this prospectus, Anchor National will submit to a court with
jurisdiction to determine whether the indemnification is against public policy
under the Act. Anchor National will be governed by final judgment of the issue.
However, if in the opinion of Anchor National's counsel this issue has been
determined by controlling precedent, Anchor National not submit the issue to a
court for determination.

EXPLANATION OF FEE TABLES AND EXAMPLES

1.  The purpose of the Fee Tables is to show you the various expenses you would
    incur directly and indirectly by investing in the contract.

2.  For certain Variable Portfolios, the adviser, SunAmerica Asset Management
    Corp., has voluntarily agreed to waive fees or reimburse certain expenses,
    if necessary, to keep annual operating expenses at or below the lesser of
    the maximum allowed by any applicable state expense limitations or the
    following percentages of each Variable Portfolio's average net assets:
    SunAmerica Balanced (1.00%); "Dogs" of Wall Street (.85%); Aggressive Growth
    (.90%); Federated Value (1.03%); Utility (1.05%); Emerging Markets (1.90%);
    International Growth and Income (1.60%); and Real Estate (1.25%). The
    adviser also may voluntarily waive or reimburse additional amounts to
    increase a Variable Portfolio's investment return. All waivers and/or
    reimbursements may be terminated at any time. Furthermore, the adviser may
    recoup any waivers or reimbursements within two years after such waivers or
    reimbursements are granted, provided that the Variable Portfolio is able to
    make such payment and remain in compliance with the foregoing expense
    limitations.

3.  The Examples assume that no transfer fees were imposed. Although premium
    taxes may apply in certain states, they are not reflected in the Examples.

4.  THESE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

THE HISTORICAL ACCUMULATION UNIT VALUES ARE CONTAINED IN APPENDIX A -- CONDENSED
                             FINANCIAL INFORMATION.

                        THE POLARIS(II) VARIABLE ANNUITY
----------------------------------------------------------------
----------------------------------------------------------------

An annuity is a contract between you and an insurance company. You are the owner
of the contract. The contract provides three main benefits:

     - Tax Deferral: This means that you do not pay taxes on your earnings from
       the annuity until you withdraw them.

     - Death Benefit: If you die during the Accumulation Phase, the insurance
       company pays a death benefit to your Beneficiary.

     - Guaranteed Income: If elected, you receive a stream of income for your
       lifetime, or another available period you select.

Tax-qualified retirement plans (e.g., IRAs, 401(k) or 403(b) plans) defer
payment of taxes on earnings until withdrawal. If you are considering funding a
tax-qualified retirement plan with an annuity, you should know that an annuity
does not provide any additional tax deferral treatment of earnings beyond the
treatment provided by the tax-qualified retirement plan itself. However,
annuities do provide other features and benefits which may be valuable to you.
You should fully discuss this decision with your financial representative.

This annuity was developed to help you contribute to your retirement savings.
This annuity works in two stages, the Accumulation Phase and the Income Phase.
Your contract is in the Accumulation Phase during the period when you make
payments into the contract. The Income Phase begins when you request us to start
making income payments to you out of the money accumulated in your contract.


The contract is called a "variable" annuity because it allows you to invest in
variable portfolios which, like mutual funds, have different investment
objectives and performance which varies. You can gain or lose money if you
invest in these Variable Portfolios. The amount of money you accumulate in your
contract depends on the performance of the Variable Portfolios in which you
invest. This contract currently offers 31 Variable Portfolios.


The contract also offers several fixed account options for varying time periods.
Fixed account options earn interest at a rate set and guaranteed by Anchor
National. If you allocate money to the fixed account options, the amount of
money that accumulates in the contract depends on the total interest credited to
the particular fixed account option(s) in which you invest.

For more information on investment options available under this contract SEE
INVESTMENT OPTIONS ON PAGE 7.

This annuity is designed to assist in contributing to retirement savings of
investors whose personal circumstances allow for a long-term investment time
horizon. As a function of the Internal Revenue Code ("IRC"), you may be assessed
a 10% federal tax penalty on any withdrawal made prior to your reaching age
59 1/2. Additionally, this contract provides that you will be charged a
withdrawal charge on each purchase payment withdrawn if that purchase payment
has not been invested in this contract for at least 7 years. Because of these
potential penalties, you should fully discuss all of the benefits and risks of
this contract with your financial representative prior to purchase.

                   PURCHASING A POLARIS(II) VARIABLE ANNUITY
----------------------------------------------------------------
----------------------------------------------------------------

An initial Purchase Payment is the money you give us to buy a contract. Any
additional money you give us to invest in the contract after purchase is a
subsequent Purchase Payment.

The following chart shows the minimum initial and subsequent Purchase Payments
permitted under your contract. These amounts depend upon whether a contract is
Qualified or Non-qualified for tax purposes. FOR FURTHER EXPLANATION, SEE TAXES

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

Prior Company approval is required to accept Purchase Payments greater than
$1,500,000. The Company reserves the right to refuse any Purchase Payment
including one which would cause the contract value or total Purchase Payments to
exceed $1,500,000 at the time of the Purchase Payment. Also, the optional
automatic payment plan allows you to make subsequent Purchase Payments of as
little as $20.00.

We may refuse any Purchase Payment. In general, we will not issue a Qualified
contract to anyone who is age 70 1/2 or older, unless it is shown that the
minimum distribution required by the IRS is being made. In addition we may not
issue a contract to anyone over age 90.

ALLOCATION OF PURCHASE PAYMENTS

We invest your Purchase Payments in the fixed and variable investment options
according to your instructions. If we receive a Purchase Payment without
allocation instructions, we will invest the money according to your last
allocation instructions. SEE INVESTMENT OPTIONS BELOW.

In order to issue your contract, we must receive your completed application,
Purchase Payment allocation instructions and any other required paperwork at our
principal place of business. We allocate your initial Purchase Payment within
two days of receiving it. If we do not have complete information necessary to
issue your contract, we will contact you. If we do not have the information
necessary to issue your contract within 5 business days we will:

     - Send your money back to you, or;

     - Ask your permission to keep your money until we get the information
       necessary to issue the contract.

ACCUMULATION UNITS

When you allocate a Purchase Payment to the Variable Portfolios, we credit your
contract with Accumulation Units of the separate account. We base the number of
Accumulation Units you receive on the unit value of the Variable Portfolio as of
the day we receive your money if we receive it before 1 p.m. Pacific Standard
Time, or on the next business day's unit value if we receive your money after 1
p.m. Pacific Standard time. The value of an Accumulation Unit goes up and down
based on the performance of the Variable Portfolios.
We calculate the value of an Accumulation Unit each day that the New York Stock
Exchange ("NYSE") is open as follows:

     1. We determine the total value of money invested in a particular Variable
        Portfolio;

     2. We subtract from that amount all applicable contract charges; and

     3. We divide this amount by the number of outstanding Accumulation Units.

We determine the number of Accumulation Units credited to your contract by
dividing the Purchase Payment by the Accumulation Unit value for the specific
Variable Portfolio.

     EXAMPLE:

     We receive a $25,000 Purchase Payment from you on Wednesday. You allocate
     the money to the Global Bond Portfolio. We determine that the value of an
     Accumulation Unit for the Global Bond Portfolio is $11.10 when the NYSE
     closes on Wednesday. We then divide $25,000 by $11.10 and credit your
     contract on Wednesday night with 2252.52 Accumulation Units for the Global
     Bond Portfolio.

Performance of the Variable Portfolios and expenses under your contract affect
Accumulation Unit values. These factors cause the value of your contract to go
up and down.

FREE LOOK

You may cancel your contract within ten days after receiving it (or longer if
required by state law). We call this a "free look." To cancel, you must mail the
contract along with your free look request to our Annuity Service Center at P.O.
Box 54299, Los Angeles, California 90054-0299. We will refund to you the value
of your contract on the day we receive your request. The amount refunded to you
may be more or less than the amount you originally invested.

Certain states require us to return your Purchase Payments upon a free look
request. Additionally, all contracts issued as an IRA require the full return of
Purchase Payments upon a free look. With respect to those contracts, we reserve
the right to put your money in the Cash Management Portfolio during the free
look period. If you cancel your contract during the free look period, we return
the greater of (1) your Purchase Payments or (2) the value of your contract. At
the end of the free look period, we allocate your money according to your
instructions.

PROSPECTUSES CONTAIN DETAILED INFORMATION ABOUT THE VARIABLE PORTFOLIOS,
INCLUDING EACH VARIABLE PORTFOLIO'S INVESTMENT OBJECTIVE AND RISK FACTORS.

FIXED ACCOUNT OPTIONS

The contract also offers seven fixed account options. Anchor National will
guarantee the interest rate earned on money you allocate to any of these fixed
account options. We currently offer fixed account options for periods of one,
three, five, seven and ten years, which we call guarantee periods. Additionally,
we guarantee the interest rate for money allocated to the six-month DCA fixed
account and/or the one year DCA fixed account (the "DCA fixed accounts") which
are available only in conjunction with the Dollar Cost Averaging Program. Please
see the section on DOLLAR COST AVERAGING ON PAGE 10 for additional information
about, including limitations on, and the availability and operation of the DCA
fixed accounts. The DCA fixed accounts are only available for new Purchase
Payments.

Each guarantee period may offer a different interest rate but will never be less
than an annual effective rate of 3%. Once established the rates for specified
payments do not change during the guarantee period. The guarantee period is that
period for which we credit the applicable rate (one, three, five, seven or ten
years).

There are three scenarios in which you may put money into the MVA fixed account
options. In each scenario your money may be credited a different rate of
interest as follows:

     - Initial Rate: Rate credited to new Purchase Payments allocated to the
       fixed account when you purchase your contract.

     - Current Rate: Rate credited to subsequent Purchase Payments allocated to
       the fixed account.

     - Renewal Rate: Rate credited to money transferred from a fixed account or
       a Variable Portfolio into a

                                        8
<PAGE>   50

       fixed account and to money remaining in a fixed account after expiration
       of a guarantee period.

Each of these rates may differ from one another. Once declared, the applicable
rate is guaranteed until the corresponding guarantee period expires.

When a guarantee period ends, you may leave your money in the same fixed
investment option. You may also reallocate your money to another fixed
investment option (other than the DCA fixed accounts) or to the Variable
Portfolios. If you want to reallocate your money to a different fixed account
option or a Variable Portfolio, you must contact us within 30 days after the end
of the current interest guarantee period and instruct us how to reallocate the
money. We do not contact you. If we do not hear from you, your money will remain
in the same fixed account option, where it will earn interest at the renewal
rate then in effect for the fixed account option.

The DCA fixed accounts also credit a fixed rate of interest. Interest is
credited to amounts allocated to the 1-year or 6-month DCA fixed account while
your investment is systematically transferred to the Variable Portfolios. The
rates applicable to the DCA fixed accounts may differ from each other and/or the
other fixed account options but will never be less than an effective rate of 3%.
See DOLLAR COST AVERAGING ON PAGE 10 for more information.

MARKET VALUE ADJUSTMENT ("MVA")

NOTE: THE FOLLOWING DISCUSSION APPLIES TO THE 3, 5, 7 AND 10-YEAR FIXED ACCOUNT
OPTIONS, ONLY. THESE OPTIONS ARE NOT AVAILABLE IN ALL STATES. PLEASE CONTACT
YOUR FINANCIAL REPRESENTATIVE FOR MORE INFORMATION.

If you take money out of the multi-year fixed account options before the end of
the guarantee period, we make an adjustment to your contract. We refer to the
adjustment as a market value adjustment (the "MVA"). The MVA reflects any
difference in the interest rate environment between the time you place your
money in the fixed account option and the time when you withdraw that money.
This adjustment can increase or decrease your contract value. You have 30 days
after the end of each guarantee period to reallocate your funds without
incurring any MVA.

We calculate the MVA by doing a comparison between current rates and the rate
being credited to you in the fixed account option. For the current rate we use a
rate being offered by us for a guarantee period that is equal to the time
remaining in the guarantee period from which you seek withdrawal. If we are not
currently offering a guarantee period for that period of time, we determine an
applicable rate by using a formula to arrive at a number between the interest
rates currently offered for the two closest periods available.

Generally, if interest rates drop between the time you put your money into the
fixed account options and the time you take it out, we credit a positive
adjustment to your contract. Conversely, if interest rates increase during the
same period, we post a negative adjustment to your contract.

Where the MVA is negative, we first deduct the adjustment from any money
remaining in the fixed account option. If there is not enough money in the fixed
account option to meet the negative deduction, we deduct the remainder from your
withdrawal. Where the MVA is positive, we add the adjustment to your withdrawal
amount.

Anchor National does not assess a MVA against withdrawals under the following
circumstances:

     - If made within 30 days after the end of a guarantee period;
     - If made to pay contract fees and charges;
     - To pay a death benefit; and
     - Upon annuitization, if occurring on the latest Annuity Date.

APPENDIX B shows how we calculate the MVA.

TRANSFERS DURING THE ACCUMULATION PHASE

During the Accumulation Phase you may transfer funds between the Variable
Portfolios and/or the fixed account options. Funds already in your contract
cannot be transferred into the DCA fixed accounts. You must transfer at least
$100. If less than $100 will remain in any Variable Portfolio after a transfer,
that amount must be transferred as well.

You may request transfers of your account value between the Variable Portfolios
and/or the fixed account options in writing or by telephone. Additionally, you
may access your account and request transfers over the internet, unless you
indicate that you do not want your account traded over the internet.
(http://www.sunamerica.com). We currently allow 15 free transfers per contract
per year. We charge $25 ($10 in Pennsylvania and Texas) for each additional
transfer in any contract year. Transfers resulting from your participation in
the DCA program count against your 15 free transfers per contract year. However,
transfers resulting from your participation in the automatic asset rebalancing
program do not count against your 15 free transfers.


We accept transfer requests by telephone unless you tell us not to on your
contract application. Additionally, you may request transfers over the internet.
When receiving instructions over the telephone or the internet, we follow
appropriate procedures to provide reasonable assurance that the transactions
executed are genuine. Thus, we are not responsible for any claim, loss or
expense from any error resulting from instructions received over the telephone
or internet. If we fail to follow our procedures, we may be liable for any
losses due to unauthorized or fraudulent instructions.


We may limit the number of transfers in any contract year or refuse any transfer
request for you or others invested in the contract if we believe that excessive
trading or a specific transfer request or group transfer requests may have a
detrimental effect on unit values or the share prices of the underlying Variable
Portfolios.

                                        9
<PAGE>   51

Where permitted by law, we may accept your authorization for a third party to
make transfers for you subject to our rules. We reserve the right to suspend or
cancel such acceptance at any time and will notify you accordingly.
Additionally, we may restrict the investment options available for transfers
during any period in which such third party acts for you. We notify such third
party beforehand regarding any restrictions. However, we will not enforce these
restrictions if we are satisfied that:

     - such third party has been appointed by a court of competent jurisdiction
       to act on your behalf; or
     - such third party is a trustee/fiduciary, for you or appointed by you, to
       act on your behalf for all your financial affairs.

We may provide administrative or other support services to independent third
parties you authorize to make transfers on your behalf. We do not currently
charge you extra for providing these support services. This includes, but is not
limited to, transfers between investment options in accordance with market
timing strategies. Such independent third parties may or may not be appointed
with us for the sale of annuities. However, WE DO NOT ENGAGE ANY THIRD PARTIES
TO OFFER INVESTMENT ALLOCATION SERVICES OF ANY TYPE. WE TAKE NO RESPONSIBILITY
FOR THE INVESTMENT ALLOCATION AND TRANSFERS TRANSACTED ON YOUR BEHALF BY SUCH
THIRD PARTIES OR FOR ANY INVESTMENT ALLOCATION RECOMMENDATIONS MADE BY SUCH
PARTIES.

For information regarding transfers during the Income Phase, SEE INCOME OPTIONS
ON PAGE 14.

We reserve the right to modify, suspend, waive or terminate these transfer
provisions at any time.

DOLLAR COST AVERAGING

The Dollar Cost Averaging ("DCA") program allows you to invest gradually in the
Variable Portfolios. Under the program you systematically transfer a set dollar
amount or percentage of portfolio value from one Variable Portfolio or the
1-year fixed account option (source accounts) to any other Variable Portfolio.
Transfers may be monthly or quarterly and count against your 15 free transfers
per contract year. You may change the frequency at any time by notifying us in
writing. The minimum transfer amount under the DCA program is $100, regardless
of the source account.
We also offer the 6-month and 1-year DCA fixed accounts exclusively to
facilitate this program. The DCA fixed accounts only accept new Purchase
Payments. You cannot transfer money already in your contract into these options.
If you allocate a Purchase Payment into a DCA fixed account, we transfer all
your money allocated to that account into the Variable Portfolios over the
selected 6-month or 1-year period. You cannot change the option or the frequency
of transfers once selected.

If allocated to the 6-month DCA fixed account, we transfer your money over a
maximum of 6 monthly transfers. We base the actual number of transfers on the
total amount allocated to the account. For example, if you allocate $500 to the
6-month DCA fixed account, we transfer your money over a period of five months,
so that each payment complies with the $100 per transfer minimum.

We determine the amount of the transfers from the 1-year DCA fixed account based
on

     - the total amount of money allocated to the account, and
     - the frequency of transfers selected.

For example, let's say you allocate $1,000 to the 1-year DCA account. You select
monthly transfers. We completely transfer all of your money to the selected
investment options over a period of ten months.

You may terminate your DCA program at any time. If money remains in the DCA
fixed accounts, we transfer the remaining money to the 1-year fixed account
option, unless we receive different instructions from you. Transfers resulting
from a termination of this program do not count towards your 15 free transfers.

The DCA program is designed to lessen the impact of market fluctuations on your
investment. However, we cannot ensure that you will make a profit. When you
elect the DCA program, you are continuously investing in securities regardless
of fluctuating price levels. You should consider your tolerance for investing
through periods of fluctuating price levels.

We reserve the right to modify, suspend or terminate this program at any time.

     EXAMPLE:

     Assume that you want to gradually move $750 each quarter from the Cash
     Management Portfolio to the Aggressive Growth Portfolio over six quarters.
     You set up dollar cost averaging and purchase Accumulation Units at the
     following values:

<TABLE>
<CAPTION>
-------------------------------------------
                ACCUMULATION      UNITS
   QUARTER          UNIT        PURCHASED
-------------------------------------------
<S>            <C>            <C>
      1            $ 7.50          100
      2            $ 5.00          150
      3            $10.00          75
      4            $ 7.50          100
      5            $ 5.00          150
      6            $ 7.50          100
-------------------------------------------
</TABLE>

     You paid an average price of only $6.67 per Accumulation Unit over six
     quarters, while the average market price actually was $7.08. By investing
     an equal amount of money each month, you automatically buy more
     Accumulation Units when the market price is low and fewer Accumulation
     Units when the market price is high. This example is for illustrative
     purposes only.

ASSET ALLOCATION REBALANCING

Earnings in your contract may cause the percentage of your investment in each
investment option to differ from your

                                       10
<PAGE>   52

original allocations. The Automatic Asset Rebalancing program addresses this
situation. At your election, we periodically rebalance your investments in the
variable Portfolios to return your allocations to their original percentages.
Asset rebalancing typically involves shifting a portion of your money out of an
investment option with a higher return into an investment option with a lower
return.

At your request, rebalancing occurs on a quarterly, semiannual or annual basis.
Transfers made as a result of rebalancing do not count against your 15 free
transfers for the contract year.

We reserve the right to modify, suspend or terminate this program at any time.

     EXAMPLE:

     Assume that you want your initial Purchase Payment split between two
     Variable Portfolios. You want 50% in the Corporate Bond Portfolio and 50%
     in the Growth Portfolio. Over the next calendar quarter, the bond market
     does very well while the stock market performs poorly. At the end of the
     calendar quarter, the Corporate Bond Portfolio now represents 60% of your
     holdings because it has increased in value and the Growth Portfolio
     represents 40% of your holdings. If you had chosen quarterly rebalancing,
     on the last day of that quarter, we would sell some of your units in the
     Corporate Bond Portfolio to bring its holdings back to 50% and use the
     money to buy more units in the Growth Portfolio to increase those holdings
     to 50%.

PRINCIPAL ADVANTAGE PROGRAM

The Principal Advantage Program allows you to invest in one or more Variable
Portfolios without putting your principal at direct risk. The program
accomplishes this by allocating your investment strategically between the fixed
account options and Variable Portfolios. You decide how much you want to invest
and approximately when you want a return of principal. We calculate how much of
your Purchase Payment to allocate to the particular fixed account option to
ensure that it grows to an amount equal to your total principal invested under
this program. We invest the rest of your principal in the Variable Portfolio(s)
of your choice.

We reserve the right to modify, suspend or terminate this program at any time.

     EXAMPLE:

     Assume that you want to allocate a portion of your initial Purchase Payment
     of $100,000 to the fixed account option. You want the amount allocated to
     the fixed account option to grow to $100,000 in 7 years. If the 7-year
     fixed account option is offering a 5% interest rate, we will allocate
     $71,069 to the 7-year fixed account option to ensure that this amount will
     grow to $100,000 at the end of the 7-year period. The remaining $28,931 may
     be allocated among the Variable Portfolios, as determined by you, to
     provide opportunity for greater growth.
VOTING RIGHTS

Anchor National is the legal owner of the Trusts' shares. However, when a
Variable Portfolio solicits proxies in conjunction with a vote of shareholders,
we must obtain your instructions on how to vote those shares. We vote all of the
shares we own in proportion to your instructions. This includes any shares we
own on our own behalf. Should we determine that we are no longer required to
comply with these rules, we will vote the shares in our own right.

SUBSTITUTION

If underlying funds of the Trusts become unavailable for investment, we may be
required to substitute shares of another underlying fund. We will seek prior
approval of the SEC and give you notice before substituting shares.
----------------------------------------------------------------
----------------------------------------------------------------
                              ACCESS TO YOUR MONEY
----------------------------------------------------------------
----------------------------------------------------------------

You can access money in your contract in two ways:

     - by making a partial or total withdrawal, and/or;

     - by receiving income payments during the Income Phase. SEE INCOME OPTIONS
       ON PAGE 14.

Generally, we deduct a withdrawal charge applicable to any total or partial
withdrawal and a MVA if a partial withdrawal comes from the 3, 5, 7 or 10 year
fixed account options. If you withdraw your entire contract value, we also
deduct premium taxes and a contract maintenance fee. SEE EXPENSES ON PAGE 13.

Your contract provides for a free withdrawal amount each year. A free withdrawal
amount is the portion of your account that we allow you to take out each year
without being charged a surrender penalty. However, upon a future full surrender
of your contract we will recoup any withdrawal charges which would have been due
if your free withdrawal had not been free.

Purchase payments, above and beyond the amount of your free withdrawal amount,
that are withdrawn prior to the end of the seventh year will result in your
paying a penalty in the form of a surrender charge. The amount of the charge and
how it applies are discussed more fully below. SEE EXPENSES ON PAGE 13. You
should consider, before purchasing this contract, the effect this charge will
have on your investment if you need to withdraw more money than the free
withdrawal amount. You should fully discuss this decision with your financial
representative.

To determine your free withdrawal amount and your withdrawal charge, we refer to
two special terms. These are penalty free earnings and the total invested
amount.

The penalty-free earnings portion of your contract is simply your account value
less your total invested amount. The total invested amount is the total of all
Purchase Payments you have made into the contract less portions of some prior
withdrawals you made. The portions of prior withdrawals that reduce your total
invested amount is as follows:

     - Free withdrawals in any year that were in excess of your penalty free
       earnings and were based on the part of the total invested amount that was
       no longer

                                       11
<PAGE>   53

       subject to withdrawal charges at the time of the withdrawal, and

     - Any prior withdrawals (including surrender charges on those withdrawals)
       of the total invested amount on which you already paid a surrender
       penalty.

When you make a withdrawal, we assume that it is taken from penalty-free
earnings first, then from the total invested amount on a first-in, first-out
basis. This means that you can also access your Purchase Payments which are no
longer subject to a withdrawal charge before those Purchase Payments which are
still subject to the withdrawal charge.

During the first year after we issue your contract your free withdrawal amount
is the greater of (1) your penalty-free earnings; and (2) if you are
participating in the Systematic Withdrawal program, a total of 10% of your total
invested amount. If you are a Washington resident, you may withdraw during the
first contract year, the greater of (1); (2); or (3) interest earnings from the
amounts allocated to the fixed account options, not previously withdrawn.

After the first contract year, you can take out the greater of the following
amounts each year (1) your penalty free earnings and any portion of your total
invested amount no longer subject to withdrawal charges; and (2) 10% of the
portion of your total invested amount that has been in your contract for at
least one year. If you are a Washington resident, your maximum free withdrawal
amount, after the first contract year, is the greater of (1); (2); or (3)
interest earnings from amounts allocated to the fixed account options, not
previously withdrawn.

We calculate charges due on a total withdrawal on the day after we receive your
request and your contract. We return to you your contract value less any
applicable fees and charges.

Under most circumstances, the partial withdrawal minimum is $1,000. We require
that the value left in any investment option be at least $100, after the
withdrawal. You must send a written withdrawal request. Unless you provide us
with different instructions, partial withdrawals will be made pro rata from each
Variable Portfolio and the fixed account option in which your contract is
invested.

Under certain Qualified plans, access to the money in your contract may be
restricted. Additionally, withdrawals made prior to age 59 1/2 may result in a
10% IRS penalty tax. SEE TAXES ON PAGE 17.

We may be required to suspend or postpone the payment of a withdrawal for any
period of time when: (1) the NYSE is closed (other than a customary weekend and
holiday closings); (2) trading with the NYSE is restricted; (3) an emergency
exists such that disposal of or determination of the value of shares of the
Variable Portfolios is not reasonably practicable; (4) the SEC, by order, so
permits for the protection of contract owners.

Additionally, we reserve the right to defer payments for a withdrawal from a
fixed account in option. Such deferrals are limited to no longer than six
months.

SYSTEMATIC WITHDRAWAL PROGRAM

During the Accumulation Phase, you may elect to receive periodic income payments
under the systematic withdrawal program. Under the program, you may choose to
take monthly, quarterly, semi-annual or annual payments from your contract.
Electronic transfer of these funds to your bank account is also available. The
minimum amount of each withdrawal is $250. If you are an Oregon resident, the
minimum withdrawal amount is $250 per withdrawal or an amount equal to your free
withdrawal amount, as described on page 10. There must be at least $500
remaining in your contract at all times. Withdrawals may be taxable and a 10%
IRS penalty tax may apply if you are under age 59 1/2. There is no additional
charge for participating in this program, although a withdrawal charge and/or
MVA may apply.

The program is not available to everyone. Please check with our Annuity Service
Center, which can provide the necessary enrollment forms. We reserve the right
to modify, suspend or terminate this program at any time.

NURSING HOME WAIVER

If you are confined to a nursing home for 60 days or longer, we may waive the
withdrawal charge and/or market value adjustment on certain withdrawals prior to
the Annuity Date (not available in Texas). The waiver applies only to
withdrawals made while you are in a nursing home or within 90 days after you
leave the nursing home. Your contract prohibits use of this waiver during the
first 90 days after you purchase your contract. In addition, the confinement
period for which you seek the waiver must begin after you purchase your
contract.

In order to use this waiver, you must submit with your withdrawal request, the
following documents: (1) a doctor's note recommending admittance to a nursing
home; (2) an admittance form which shows the type of facility you entered; and
(3) a bill from the nursing home which shows that you met the 60 day confinement
requirement.

MINIMUM CONTRACT VALUE

Where permitted by state law, we may terminate your contract if both of the
following occur: (1) your contract is less than $500 as a result of withdrawals;
and (2) you have not made any Purchase Payments during the past three years. We
will provide you with sixty days written notice. At the end of the notice
period, we will distribute the contract's remaining value to you.

----------------------------------------------------------------
----------------------------------------------------------------
                                  DEATH BENEFIT
----------------------------------------------------------------
----------------------------------------------------------------

If you die during the Accumulation Phase of your contract, we pay a death
benefit to your Beneficiary. At the time you purchase your contract, you must
select one of the two death benefits described below. Once selected, you can not
change your death benefit option. You should discuss the available options with
your financial representative to determine which option is best for you.

                                       12
<PAGE>   54

OPTION 1 - PURCHASE PAYMENT ACCUMULATION OPTION

The death benefit is the greater of:

     1. the value of your contract at the time we receive satisfactory proof of
        death; or

     2. total Purchase Payments less withdrawals (and any fees or charges
        applicable to such withdrawals), compounded at a 4% annual growth rate
        until the date of death (3% growth rate if 70 or older at the time of
        contract issue) plus any Purchase Payments less withdrawals recorded
        after the date of death (and any fees or charges applicable to such
        withdrawals); or

     3. the value of your contract on the seventh contract anniversary, plus any
        Purchase Payments and less any withdrawals (and any fees or charges
        applicable to such withdrawals), since the seventh contract anniversary,
        all compounded at a 4% annual growth rate until the date of death (3%
        growth rate if age 70 or older at the time of contract issue) plus any
        Purchase Payments less withdrawals recorded after the date of death (and
        any fees or charges applicable to such withdrawals).

OPTION 2 - MAXIMUM ANNIVERSARY OPTION

The death benefit is the greater of:

     1. the value of your contract at the time we receive satisfactory proof of
        death; or

     2. total Purchase Payments less any withdrawals (and any fees or charges
        applicable to such withdrawals); or

     3. the maximum anniversary value on any contract anniversary prior to your
        81st birthday. The anniversary value equals the value of your contract
        on a contract anniversary plus any Purchase Payments and less any
        withdrawals (and any fees or charges applicable to such withdrawals),
        since that contract anniversary.

If you are age 90 or older at the time of death and selected the Option 2 death
benefit, the death benefit will be equal to the value of your contract at the
time we receive satisfactory proof of death. Accordingly, you do not get the
advantage of option 2 if:

     - you are over age 80 at the time of contract issue, or

     - you are 90 or older at the time of your death.

We do not pay the death benefit if you die after you switch to the Income Phase.
However, if you die during the Income Phase, your Beneficiary receives any
remaining guaranteed income payments in accordance with the income option you
selected. SEE INCOME OPTIONS ON PAGE 14.

You name your Beneficiary. You may change the Beneficiary at any time, unless
you previously made an irrevocable Beneficiary designation.

We pay the death benefit when we receive satisfactory proof of death. We
consider the following satisfactory proof of death:

     1. a certified copy of the death certificate; or

     2. a certified copy of a decree of a court of competent jurisdiction as to
        the finding of death; or

     3. a written statement by a medical doctor who attended the deceased at the
        time of death; or

     4. any other proof satisfactory to us.

We may require additional proof before we pay the death benefit.

The death benefit payment must begin immediately upon receipt of all necessary
documents. In any event, the death benefit must be paid within 5 years of the
date of death unless the Beneficiary elects to have it payable in the form of an
income option. If the Beneficiary elects an income option, it must be paid over
the Beneficiary's lifetime or for a period not extending beyond the
Beneficiary's life expectancy. Payments must begin within one year of your
death.

If the Beneficiary is the spouse of a deceased owner, he or she can elect to
continue the Contract at the then current value. If the Beneficiary/spouse
continues the contract, we do not pay a death benefit to him or her.

If a Beneficiary does not elect a specific form of pay out within 60 days of our
receipt of proof of death, we pay a lump sum death benefit to the Beneficiary.

                                    EXPENSES
----------------------------------------------------------------
----------------------------------------------------------------

There are charges and expenses associated with your contract. These charges and
expenses reduce your investment return. We will not increase the contract
maintenance fee or the insurance and withdrawal charges under your contract.
However, the investment charges under your contract may increase or decrease.
Some states may require that we charge less than the amounts described below.

INSURANCE CHARGES

The amount of this charge is 1.52% annually, of the value of your contract
invested in the Variable Portfolios. We deduct the charge daily.

The insurance charge compensates us for the mortality and expense risks and the
costs of contract distribution assumed by Anchor National.

If these charges do not cover all of our expenses, we will pay the difference.
Likewise, if these charges exceed our expenses, we will keep the difference.

WITHDRAWAL CHARGES

The contract provides a free withdrawal amount every year. SEE ACCESS TO YOUR
MONEY, PAGE 11. If you take money out in excess of the free withdrawal amount,
and upon a full surrender, you may incur a withdrawal charge.

                                       13
<PAGE>   55

We apply a withdrawal charge against each Purchase Payment you put into the
contract. After a Purchase Payment has been in the contract for 7 complete
years, no withdrawal charge applies. The withdrawal charge equals a percentage
of the Purchase Payment you take out of the contract. The withdrawal charge
percentage declines each year a Purchase Payment is in the contract, as follows

<TABLE>

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

When calculating the withdrawal charge, we treat withdrawals as coming first
from the Purchase Payments that have been in your contract the longest. However,
for tax purposes, your withdrawals are considered earnings first, then Purchase
Payments.

Whenever possible, we deduct the withdrawal charge from the money remaining in
your contract. If you withdraw all of your contract value, we deduct any
applicable withdrawal charges from the amount withdrawn.

We will not assess a withdrawal charge for money withdrawn to pay a death
benefit or to pay contract fees or charges. We will not assess a withdrawal
charge when you switch to the Income Phase, except when you elect to receive
income payments using the Income Protector feature. If you elect to receive
income payments using the Income Protector feature, we assess the entire
withdrawal charge applicable to Purchase Payments remaining in your contract
when calculating your income benefit base. SEE INCOME OPTIONS BELOW.

Withdrawals made prior to age 59 1/2 may result in tax penalties. SEE TAXES ON
PAGE 17.

INVESTMENT CHARGES

Charges are deducted from your Variable Portfolios for the advisory and other
expenses of the Variable Portfolios. THE FEE TABLES LOCATED AT PAGE 4 illustrate
these charges and expenses. For more detailed information on these investment
charges, refer to the prospectuses for the Trusts, enclosed or attached.

CONTRACT MAINTENANCE FEE

During the Accumulation Phase, we subtract a contract maintenance fee from your
account once per year. This charge compensates us for the cost of contract
administration. We deduct the $35 contract maintenance fee ($30 in North Dakota)
from your account value on your contract anniversary. If you withdraw your
entire contract value, we deduct the fee from that withdrawal.

If your contract value is $50,000 or more on your contract anniversary date, we
will waive the charge. This waiver is subject to change without notice.

TRANSFER FEE
We currently permit 15 free transfers between investment options each contract
year. We charge you $25 for each additional transfer that contract year ($10 in
Pennsylvania and Texas). SEE INVESTMENT OPTIONS ON PAGE 7.

PREMIUM TAX

Certain states charge the Company a tax on the premiums you pay into the
contract. We deduct from your contract these premium tax charges. Currently we
deduct the charge for premium taxes when you take a full withdrawal or begin the
Income Phase of the contract. In the future, we may assess this deduction at the
time you put Purchase Payment(s) into the contract or upon payment of a death
benefit.

APPENDIX C provides more information about premium taxes.

INCOME TAXES

We do not currently deduct income taxes from your contract. We reserve the right
to do so in the future.

REDUCTION OR ELIMINATION OF CHARGES AND EXPENSES, AND ADDITIONAL AMOUNTS
CREDITED

Sometimes sales of the contracts to groups of similarly situated individuals may
lower our administrative and/or sales expenses. We reserve the right to reduce
or waive certain charges and expenses when this type of sale occurs. In
addition, we may also credit additional interest to policies sold to such
groups. We determine which groups are eligible for such treatment. Some of the
criteria we evaluate to make a determination are: size of the group; amount of
expected Purchase Payments; relationship existing between us and prospective
purchaser; nature of the purchase; length of time a group of contracts is
expected to remain active; purpose of the purchase and whether that purpose
increases the likelihood that our expenses will be reduced; and/or any other
factors that we believe indicate that administrative and/or sales expenses may
be reduced.

Anchor National may make such a determination regarding sales to its employees,
it affiliates' employees and employees of currently contracted broker-dealers;
its registered representatives and immediate family members of all of those
described.

We reserve the right to change or modify any such determination or the treatment
applied to a particular group, at any time.

                                 INCOME OPTIONS
----------------------------------------------------------------
----------------------------------------------------------------

ANNUITY DATE

During the Income Phase, we use the money accumulated in your contract to make
regular income payments to you. You may switch to the Income Phase any time
after your 2nd

                                       14
<PAGE>   56

contract anniversary. You select the month and year you want income payments to
begin. The first day of that month is the Annuity Date. You may change your
Annuity Date, so long as you do so at least seven days before the income
payments are scheduled to begin. Once you begin receiving income payments, you
cannot change your income option. Except as indicated under Option 5 below, once
you begin receiving income payments, you cannot otherwise access your money
through a withdrawal or surrender.

Income payments must begin on or before your 90th birthday or on your tenth
contract anniversary, whichever occurs later. If you do not choose an Annuity
Date, your income payments will automatically begin on this date. Certain states
may require your income payments to start earlier.

If the Annuity Date is past your 85th birthday, your contract could lose its
status as an annuity under Federal tax laws. This may cause you to incur adverse
tax consequences.

In addition, most Qualified contracts require you to take minimum distributions
after you reach age 70 1/2. SEE TAXES ON PAGE 17.

INCOME OPTIONS

Currently, this Contract offers five income options. If you elect to receive
income payments but do not select an option, your income payments will be made
in accordance with option 4 for a period of 10 years. For income payments based
on joint lives, we pay according to option 3.

We base our calculation of income payments on the life of the Annuitant and the
annuity rates set forth in your contract. As the contract owner, you may change
the Annuitant at any time prior to the Annuity Date. You must notify us if the
Annuitant dies before the Annuity Date and designate a new Annuitant.

     OPTION 1 - LIFE INCOME ANNUITY

This option provides income payments for the life of the Annuitant. Income
payments stop when the Annuitant dies.

     OPTION 2 - JOINT AND SURVIVOR LIFE ANNUITY

This option provides income payments for the life of the Annuitant and for the
life of another designated person. Upon the death of either person, we will
continue to make income payments during the lifetime of the survivor. Income
payments stop when the survivor dies.

     OPTION 3 - JOINT AND SURVIVOR LIFE ANNUITY WITH 10 OR 20 YEARS GUARANTEED

This option is similar to option 2 above, with an additional guarantee of
payments for at least 10 years. If the Annuitant and the survivor die before all
of the guaranteed income payments have been made, the remaining payments are
made to the Beneficiary under your contract.

     OPTION 4 - LIFE ANNUITY WITH 10 OR 20 YEARS GUARANTEED

This option is similar to option 1 above. In addition, this option provides a
guarantee that income payments will be made for at least 10 or 20 years. You
select the number of years. If the Annuitant dies before all guaranteed income
payments are made, the remaining income payments go to the Beneficiary under
your contract.

     OPTION 5 - INCOME FOR A SPECIFIED PERIOD

This option provides income payments for a guaranteed period ranging from 5 to
30 years. If the Annuitant dies before all the guaranteed income payments are
made, the remaining income payments are made to the Beneficiary under your
contract. Additionally, if variable income payments are elected under this
option, you (or the Beneficiary under the contract if the Annuitant dies prior
to all guaranteed payments being made) may redeem the contract value after the
Annuity Date. The amount available upon such redemption would be the discounted
present value of any remaining guaranteed payments.

The value of an Annuity Unit, regardless of the option chosen, takes into
account the Mortality and Expense Risk Charge. Since Option 5 does not contain
an element of mortality risk, no benefit is derived from this charge.

Please read the Statement of Additional Information ("SAI") for a more detailed
discussion of the income options.

FIXED OR VARIABLE INCOME PAYMENTS

You can choose income payments that are fixed, variable or both. If at the date
when income payments begin you are invested in the Variable Portfolios only,
your income payments will be variable. If your money is only in fixed accounts
at that time, your income payments will be fixed in amount. Further, if you are
invested in both fixed and variable investment options when income payments
begin, your payments will be fixed and variable. If income payments are fixed,
Anchor National guarantees the amount of each payment. If the income payments
are variable the amount is not guaranteed.

INCOME PAYMENTS

We make income payments on a monthly, quarterly, semiannual or annual basis. You
instruct us to send you a check or to have the payments directly deposited into
your bank account. If state law allows, we distribute annuities with a contract
value of $5,000 or less in a lump sum. Also, if the selected income option
results in income payments of less than $50 per payment, we may decrease the
frequency of payments, state law allowing.

If you are invested in the Variable Portfolios after the Annuity date, your
income payments vary depending on four things:

     - for life options, your age when payments begin, and;

     - the value of your contract in the Variable Portfolios on the Annuity
       Date, and;

                                       15
<PAGE>   57

     - the 3.5% assumed investment rate used in the annuity table for the
       contract, and;

     - the performance of the Variable Portfolios in which you are invested
       during the time you receive income payments.

If you are invested in both the fixed account options and the Variable
Portfolios after the Annuity Date, the allocation of funds between the fixed and
variable options also impacts the amount of your annuity payments.

TRANSFERS DURING THE INCOME PHASE

During the Income Phase, one transfer per month is permitted between the
Variable Portfolios. No other transfers are allowed during the Income Phase.

DEFERMENT OF PAYMENTS

We may defer making fixed payments for up to six months, or less if required by
law. Interest is credited to you during the deferral period.

THE INCOME PROTECTOR FEATURE

The Income Protector feature is a future "safety net" which offers you the
ability to receive a guaranteed fixed minimum retirement income when you switch
to the Income Phase. With the Income Protector feature you know the level of
minimum income that will be available to you upon annuitization, regardless of
fluctuating market conditions.

The Income Protector is a standard feature of your contract, if available in
your state. There is no additional charge associated with this feature.

Other options were previously available under the Income Protector feature.
Generally, if you purchased your contract between November 2, 1998 and March 31,
1999 and the Income Protector feature was available in your state at that time,
the other provisions continue to apply to your contract. Please contact our
Annuity Service Center for more information.

We reserve the right to modify, suspend or terminate the Income Protector
feature at any time.

HOW WE DETERMINE THE AMOUNT OF YOUR MINIMUM GUARANTEED INCOME

We base the amount of minimum income available to you if you elect to receive
income payments using the Income Protector feature upon a calculation we call
the income benefit base.

The income benefit base is only a calculation. It does not represent a contract
value, nor does it guarantee performance of the Variable Portfolios in which you
invest.

Your income benefit base increases if you make subsequent Purchase Payments and
decreases if you withdraw money from your contract. The exact income benefit
base calculation is equal to (a) plus (b) minus (c) where:

     (a) is equal to, for the first year of calculation, your initial Purchase
         Payment, or for each subsequent year of calculation, the income benefit
         base on the prior contract anniversary, and;

     (b) is equal to the total of all Purchase Payments made to the contract
         since the last contract anniversary, and;

     (c) is equal to all withdrawals and applicable fees and charges since the
         last contract anniversary, in an amount proportionate to the amount by
         which such withdrawals decreased your contract value.

ELECTING TO RECEIVE INCOME PAYMENTS

You may elect to begin the Income Phase of your contract using the Income
Protector feature ONLY within the 30 days after the seventh or later contract
anniversary.

The contract anniversary prior to your election to begin receiving income
payments is your income benefit date. This is the date as of which we calculate
your income benefit base to use in determining your guaranteed minimum fixed
retirement income. Your final income benefit base is equal to (a) minus (b)
where:

     (a) is equal to your income benefit base as of your income benefit date,
         and;

     (b) is equal to any partial withdrawals of contract value and any charges
         applicable to those withdrawals and any withdrawal charges otherwise
         applicable, calculated as if you fully surrender your contract as the
         income benefit date, and any applicable premium taxes.

To arrive at the minimum guaranteed retirement income available to you we apply
your final income benefit base to the annuity rates stated in your Income
Protector endorsement for the income option you select. You then choose if you
would like to receive that income annually, semi-annually quarterly or monthly
for the time guaranteed under your selected income option. The income options
available when using the Income Protector feature to receive your retirement
income are:

     - Life Annuity with 10 Years Guaranteed, or

     - Joint and Survivor Life Annuity with 20 Years Guaranteed

At the time you elect to begin receiving income payments, we will calculate your
annual income using both your income benefit base and your contract value. We
will use the same income option for each calculation, however, the annuity

                                       16
<PAGE>   58

factors used to calculate your income under the Income Protector feature will be
different. You will receive whichever provides a greater stream of income. If
you elect to receive income payments using the Income Protector feature your
income payments will be fixed in amount. You are not required to use the Income
Protector feature to receive income payments.
NOTE TO QUALIFIED CONTRACT HOLDERS

Qualified contracts generally require that you select an income option which
does not exceed your life expectancy. That restriction, if it applies to you,
may limit your ability to use the Income Protector feature.

You may wish to consult your tax advisor for information concerning your
particular circumstances.

NOTE: WE PREPARED THE FOLLOWING INFORMATION ON TAXES AS A GENERAL DISCUSSION OF
THE SUBJECT. IT IS NOT TAX ADVICE. WE CAUTION YOU TO SEEK COMPETENT TAX ADVICE
ABOUT YOUR OWN CIRCUMSTANCES. WE DO NOT GUARANTEE THE TAX STATUS OF YOUR
ANNUITY. TAX LAWS CONSTANTLY CHANGE, THEREFORE WE CANNOT GUARANTEE THAT THE
INFORMATION CONTAINED HEREIN IS COMPLETE AND/OR ACCURATE.

ANNUITY CONTRACTS IN GENERAL

The Internal Revenue Code ("IRC") provides for special rules regarding the tax
treatment of annuity contracts. Generally, taxes on the earnings in your annuity
contract are deferred until you take the money out. Qualified retirement
investments automatically provide tax deferral regardless of whether the
underlying contract is an annuity. Different rules apply depending on how you
take the money out and whether your contract is Qualified or Non-qualified.

If you do not purchase your contract under a pension plan, a specially sponsored
employer program or an individual retirement account, your contract is referred
to as a Non-qualified contract. A Non-qualified contract receives different tax
treatment than a Qualified contract. In general, your cost basis in a
Non-qualified contract is equal to the Purchase Payments you put into the
contract. You have already been taxed on the cost basis in your contract.

If you purchase your contract under a pension plan, a specially sponsored
employer program or as an individual retirement account, your contract is
referred to as a Qualified contract. Examples of qualified plans are: Individual
Retirement Accounts ("IRAs"), Roth IRAs, Tax-Sheltered Annuities (referred to as
403(b) contracts), H.R. 10 Plans (referred to as Keogh Plans) and pension and
profit sharing plans, including 401(k) plans. Typically you have not paid any
tax on the Purchase Payments used to buy your contract and therefore, you have
no cost basis in your contract.

TAX TREATMENT OF DISTRIBUTIONS -
NON-QUALIFIED CONTRACTS

If you make a withdrawal from a Non-qualified contract, the IRC treats such a
withdrawal as first coming from the earnings and then as coming from your
Purchase Payments. For income payments, any portion of each payment that is
considered a return of your Purchase Payment will not be taxed. Withdrawn
earnings are treated as income to you and are taxable. The IRC provides for a
10% penalty tax on any earnings that are withdrawn other than in conjunction
with the following circumstances: (1) after reaching age 59 1/2; (2) when paid
to your Beneficiary after you die; (3) after you become disabled (as defined in
the IRC); (4) when paid

                                       17
<PAGE>   59

in a series of substantially equal installments made for your life or for the
joint lives of you and you Beneficiary; (5) under an immediate annuity; or (6)
which come from Purchase Payments made prior to August 14, 1982.

TAX TREATMENT OF DISTRIBUTIONS - QUALIFIED CONTRACTS

Generally, you have not paid any taxes on the Purchase Payments used to buy a
Qualified contract. Any amount of money you take out as a withdrawal or as
income payments is taxable income. The IRC further provides for a 10% penalty
tax on any withdrawal or income payment paid to you other than in conjunction
with the following circumstances: (1) after reaching age 59 1/2; (2) when paid
to your Beneficiary after you die; (3) after you become disabled (as defined in
the IRC); (4) in a series of substantially equal installments made for your life
or for the joint lives of you and your Beneficiary; (5) to the extent such
withdrawals do not exceed limitations set by the IRC for amounts paid during the
taxable year for medical care; (6) to fund higher education expenses (as defined
in IRC); (7) to fund certain first-time home purchase expenses; and, except in
the case of an IR; (8) when you separate from service after attaining age 55;
and (9) when paid to an alternate payee pursuant to a qualified domestic
relations order.

The IRC limits the withdrawal of Purchase Payments from certain Tax-Sheltered
Annuities. Withdrawals can only be made when an owner: (1) reaches age 59 1/2;
(2) leaves his or her job; (3) dies; (4) becomes disabled (as defined in the
IRC); or (5) experiences a hardship (as defined in the IRC). In the case of
hardship, the owner can only withdraw Purchase Payments.

MINIMUM DISTRIBUTIONS

Generally, the IRS requires that you begin taking annual distributions from
qualified annuity contracts by April 1 of the calendar year following the later
of (1) the calendar year in which you attain age 70 1/2 or (2) the calendar year
in which you retire.

We currently waive surrender charges and MVA on withdrawals taken to meet
minimum distribution requirements. Current operational practice is to provide a
free withdrawal of the greater of the contract's maximum penalty free amount or
the required minimum distribution amount for a particular contract (but not
both).

Failure to satisfy the minimum distribution requirements may result in a tax
penalty. You should consult your tax advisor for more information.

DIVERSIFICATION

The IRC imposes certain diversification requirements on the underlying
investments for a variable annuity. We believe that each underlying Variable
Portfolios' management monitors the Variable Portfolios so as to comply with
these requirements. To be treated as a variable annuity for tax purposes, the
underlying investments must meet these requirements.

The diversification regulations do not provide guidance as to the circumstances
under which you, because of the degree of control you exercise over the
underlying investments, and not Anchor National, would be considered the owner
of the shares of the Variable Portfolios. It is unknown to what extent owners
are permitted to select investments, to make transfers among Variable Portfolios
or the number and type of Variable Portfolios owners may select from. If any
guidance is provided which is considered a new position, then the guidance would
generally be applied prospectively. However, if such guidance is considered not
to be a new position, it may be applied retroactively. This would mean you, as
the owner of the contract, could be treated as the owner of the underlying
Variable Portfolios. Due to the uncertainty in this area, we reserve the right
to modify the contract in an attempt to maintain favorable tax treatment.

----------------------------------------------------------------
----------------------------------------------------------------
                                   PERFORMANCE
----------------------------------------------------------------
----------------------------------------------------------------

We advertise the Cash Management Portfolio's yield and effective yield. In
addition, the other Variable Portfolios advertise total return, gross yield and
yield-to-maturity. These figures represent past performance of the Variable
Portfolios. These performance numbers do not indicate future results.

When we advertise performance for periods prior to the date the contracts were
first issued, we derive the figures from the performance of the corresponding
portfolios for the Trusts, if available. We modify these numbers to reflect
charges and expenses as if the contract was in existence during the period
stated in the advertisement. Figures calculated in this manner do not represent
actual historic performance of the particular Variable Portfolio.

Consult the SAI for more detailed information regarding the calculation of
performance data. The performance of each Variable Portfolio may also be
measured against unmanaged market indices. The indices we use include but are
not limited to the Dow Jones Industrial Average, the Standard & Poor's 500, the
Russell 1000 Growth Index, the Morgan Stanley Capital International Europe,
Australia and Far East Index ("EAFE") and the Morgan Stanley Capital
International World Index. We may compare the Variable Portfolios' performance
to that of other variable annuities with similar objectives and policies as
reported by independent ranking agencies such as Morningstar, Inc., Lipper
Analytical Services, Inc. or Variable Annuity Research & Data Service ("VARDS").

Anchor National may also advertise the rating and other information assigned to
it by independent industry ratings organizations. Some of those organizations
are A.M. Best Company ("A.M. Best"), Moody's Investor's Service
                                       18

("Moody's"), Standard & Poor's Insurance Rating Services ("S&P"), and Duff &
Phelps. A.M. Best's and Moody's ratings reflect their current opinion of our
financial strength and performance in comparison to others in the life and
health insurance industry. S&P's and Duff & Phelps' ratings measure the ability
of an insurance company to meet its obligations under insurance policies it
issues. These two ratings do not measure the insurer's ability to meet
non-policy obligations. Ratings in general do not relate to the performance of
the Variable Portfolios.

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

ANCHOR NATIONAL

Anchor National is a stock life insurance company originally organized under the
laws of the state of California in April 1965. On January 1, 1996, Anchor
National redomesticated under the laws of the state of Arizona.

Anchor National and its affiliates, SunAmerica Life Insurance Company, First
SunAmerica Life Insurance Company, CalAmerica Life Insurance Company, SunAmerica
National Life Insurance Company, SunAmerica Asset Management Corp., Resources
Trust Company, and the SunAmerica Financial Network, Inc. broker-dealers,
specialize in retirement savings and investment products and services. Business
focuses include fixed and variable annuities, mutual funds, broker-dealer
services and trust administration services.

THE SEPARATE ACCOUNT

Anchor National established Variable Separate Account ("separate account"),
under Arizona law on January 1, 1996 when it assumed the separate account,
originally established under California law on June 25, 1981. The separate
account is registered with the SEC as a unit investment trust under the
Investment Company Act of 1940, as amended.

Anchor National owns the assets in the separate account. However, the assets in
the separate account are not chargeable with liabilities arising out of any
other business conducted by Anchor National. Income gains and losses (realized
and unrealized) resulting from assets in the separate account are credited to or
charged against the separate account without regard to other income gains or
losses of Anchor National.

THE GENERAL ACCOUNT

Money allocated to the fixed account options goes into Anchor National's general
account. The general account consists of all of Anchor National's assets other
than assets attributable to a separate account. All of the assets in the general
account are chargeable with the claims of any Anchor National contract holders
as well as all of its creditors. The general account funds are invested as
permitted under state insurance laws.

DISTRIBUTION OF THE CONTRACT

Registered representatives of broker-dealers sell the contract. We pay
commissions to these representatives for the sale of the contracts. We do not
expect the total commissions to exceed 7% of your Purchase Payments. We may also
pay a bonus to representatives for contracts which stay active for a particular
period of time, in addition to standard commissions. We do not deduct
commissions paid to registered representatives directly from your Purchase
Payments.

From time to time, we may pay or allow additional promotional incentives in the
form of cash or other compensation. We reserve the right to offer these
additional incentives only to certain broker-dealers that sell or are expected
to sell, certain minimum amounts of the contract, or other contracts offered by
us. Promotional incentives may change at any time.

SunAmerica Capital Services, Inc., 733 Third Avenue, 4th Floor, New York, New
York 10017 distributes the contracts. SunAmerica Capital Services, an affiliate
of Anchor National, is registered as a broker-dealer under the Exchange Act of
1934 and is a member of the National Association of Securities Dealers, Inc. No
underwriting fees are paid in connection with the distribution of the contracts.

ADMINISTRATION

We are responsible for the administrative servicing of your contract. Please
contact our Annuity Service Center
at 1-800-445-SUN2, if you have any comment, question or service request.

We send out transaction confirmations and quarterly statements. Transactions
made pursuant to contractual or systematic agreements, such as deduction of the
annual maintenance fee and dollar cost averaging, may be confirmed quarterly.
Purchase payments received through the automatic payment plan or a salary
reduction arrangement, may also be confirmed quarterly. For all other
transactions, we send confirmations immediately. It is your responsibility to
review these documents carefully and notify us of any inaccuracies immediately.
We investigate all inquiries. To the extent that we believe we made an error, we
retroactively adjust your contract, provided you notify us within 30 days of
receiving the transaction confirmation or quarterly statement. Any other
adjustments we deem warranted are made as of the time we receive notice of the
error.

YEAR 2000

The Year 2000 issue arose from computer programs written using two digits rather
than four digits to define the applicable year. This possibly could have caused
a failure of the information technology systems (IT systems) and other equipment
containing imbedded technology (non-IT systems) in the year 2000. The Company
implemented a plan to address the Year 2000 issue and to assess Year 2000 issues
relating to third parties with which the Company has critical relationships. The
Company's cost to make necessary repairs had no significant impact on its
results of operations. The

                                       19
<PAGE>   61

Company has not experienced any business disruption from the Year 2000 issue.
Its IT and non-IT systems were compliant on January 1, 2000, and there have been
no problems related to any third parties compliance.

LEGAL PROCEEDINGS

There are no pending legal proceedings affecting the separate account. Anchor
National and its subsidiaries engage in various kinds of routine litigation. In
management's opinion, these matters are not of material importance to their
respective total assets nor are they material with respect to the separate
account.

OWNERSHIP

The Polaris(II) Variable Annuity is a Flexible Payment Group Deferred Annuity
contract. We issue a group contract to a contract holder for the benefit of the
participants in the group. As a participant in the group, you will receive a
certificate which evidences your ownership. As used in this prospectus, the term
contract refers to your certificate. In some states, a Flexible Payment
Individual Modified Guaranteed and Variable Deferred Annuity contract is
available instead. Such a contract is identical to the contract described in
this prospectus, with the exception that we issue it directly to the owner.

CUSTODIAN

State Street Bank and Trust Company, 255 Franklin Street, Boston, Massachusetts
02110, serves as the custodian of the assets of the separate account. Anchor
National pays State Street Bank for services provided, based on a schedule of
fees.

INDEPENDENT ACCOUNTANTS

The audited consolidated financial statements of Anchor National as of December
31, 1999, December 31, 1998 and September 30, 1998 and for the year ended
December 31, 1999, for the three months ended December 31, 1998 and for each of

                  APPENDIX B - MARKET VALUE ADJUSTMENT ("MVA")
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
The MVA reflects the impact that changing interest rates have on the value of
money invested at a fixed interest rate. The longer the period of time remaining
in the term you initially agreed to leave your money in the fixed account
option, the greater the impact of changing interest rates. The impact of the MVA
can be either positive or negative, and is computed by multiplying the amount
withdrawn, transferred or switched to the Income Phase by the following factor:

                          [(1+I/(1+J+0.005)](N/12) - 1

The MVA formula may differ in certain states
  where:
        I is the interest rate you are earning on the money invested in the
        fixed account option;
        J is the interest rate then currently available for the period of time
        equal to the number of years remaining in the term you initially agreed
        to leave your money in the fixed account option; and
        N is the number of full months remaining in the term you initially
        agreed to leave your money in the fixed account option.
EXAMPLES OF THE MVA
The examples below assume the following:
     (1) You made an initial Purchase Payment of $10,000 and allocated it to the
         10-year fixed account option at a rate of 5%;
     (2) You make a partial withdrawal of $4,000 when 1 1/2 years (18 months)
         remain in the 10-year term you initially agreed to leave your money in
         the fixed account option (N=18); and
     (3) You have not made any other transfers, additional Purchase Payments, or
         withdrawals.
No withdrawal charges are reflected because your Purchase Payment has been in
the contract for seven full years. If a withdrawal charge applies, it is
deducted before the MVA. The MVA is assessed on the amount withdrawn less any
withdrawal charges.
POSITIVE ADJUSTMENT
Assume that on the date of withdrawal, the interest rate in effect for a new
Purchase Payments in the 1-year fixed account option is 3.5% and the 3-year
fixed account option is 4.5%. By linear interpolation, the interest rate for the
remaining 2 years (1 1/2 years rounded up to the next full year) in the contract
is calculated to be 4%.
The MVA factor is = [(1+I/(1+J+0.005)](N/12) - 1
                  = [(1.05)/(1.04+0.005)](18/12) - 1
                  = (1.004785)(1.5) - 1
                  = 1.007186 - 1
                  = + 0.007186
The requested withdrawal amount is multiplied by the MVA factor to determine the
MVA:
                         $4,000 x (+0.007186) = +$28.74
$28.74 represents the MVA that would be added to your withdrawal.
NEGATIVE ADJUSTMENT
Assume that on the date of withdrawal, the interest rate in effect for new
Purchase Payments in the 1-year fixed account option is 5.5% and the 3-year
fixed account option is 6.5%. By linear interpolation, the interest rate for the
remaining 2 years (1 1/2 years rounded up to the next full year) in the contract
is calculated to be 6%.
The MVA factor is = [(1+I)/(1+J+0.005)](N/12) - 1
                  = [(1.05)/(1.06+0.005)](18/12) - 1
                  = (0.985915)(1.5) - 1
                  = 0.978948 - 1
                  = - 0.021052
The requested withdrawal amount is multiplied by the MVA factor to determine the
MVA:
                        $4,000 X (- 0.021052) = -$84.21
$84.21 represents the MVA that will be deducted from the money remaining in the
10-year fixed account option.
