                                VARIABLE ANNUITY
    
 
   
THIS PROFILE IS A SUMMARY OF SOME OF THE MORE IMPORTANT POINTS THAT YOU SHOULD
KNOW AND CONSIDER BEFORE PURCHASING THE POLARIS CLASS A VARIABLE ANNUITY. THE
ANNUITY IS MORE FULLY DESCRIBED IN THE PROSPECTUS. PLEASE READ THE PROSPECTUS
CAREFULLY.
    
 
   
                                  May 3, 1999
    
 
- ----------------------------------------------------------------
- ----------------------------------------------------------------
   
                    1. THE POLARIS CLASS A VARIABLE ANNUITY
    
- ----------------------------------------------------------------
- ----------------------------------------------------------------
 
   
The Polaris Class A 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 Class A offers a diverse selection of money managers and investment
options. You may divide your money among any or all 26 variable portfolios and 7
fixed account options. Your investment is not guaranteed. The value of your
Polaris Class A 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. An
IRS penalty tax 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 also elect to take income
payments under the Income Protection program, subject to the provisions thereof.

                        3. PURCHASING A POLARIS CLASS A
    
   
                           VARIABLE ANNUITY CONTRACT
    
- ----------------------------------------------------------------
- ----------------------------------------------------------------
 
   
You can buy a contract through your Edward Jones investment representative, who
can also help you complete the proper forms. For non-qualified contracts, the
minimum initial gross 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 gross 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.

time to time, however, we will never credit less than a 3% compounded effective
yield. 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

                ----------------------------------------------------------------
                ----------------------------------------------------------------
                                  5. EXPENSES
                ----------------------------------------------------------------
                ----------------------------------------------------------------
 
We deduct insurance charges, to cover our mortality and expense risks, which
equal 0.85% annually of the average daily value of your contract allocated to
the variable portfolios.
 
   
We apply an up-front sales charge against each gross purchase payment you make.
The sales charge equals a percentage of each gross purchase payment. The sales
charge ranges from 0.50% to 5.75%, depending upon your investment amount. You
may be entitled to a reduced sales charge if you agree to contribute additional
money to your contract within a 13-month period or if you have related contracts
with us.
    
 
   
For investment amounts of $1,000,000 or more, we deduct, from your contract
value, a withdrawal charge of 0.50% for amounts withdrawn from any Purchase
Payment invested less than 12 months prior to such withdrawal.
    
 
   
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 .58% to 1.90%.
    
 
Each year, you are allowed to make 15 transfers without charge. After your first
15 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 assessed 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 0.85%
insurance charges and the investment charges for each variable portfolio.
 
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. We assume an up-front sales charge of 5.75% and a premium
tax of 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% IRS penalty tax for distributions or
withdrawals before age 59 1/2.
 
                ----------------------------------------------------------------
                ----------------------------------------------------------------
                            7. ACCESS TO YOUR MONEY
                ----------------------------------------------------------------
                ----------------------------------------------------------------
 
Withdrawals may be made from your contract in the amount of $1,000 or more. You
may request a withdrawal in writing or by establishing systematic withdrawals.
Under systematic withdrawals, the minimum withdrawal amount is $250.
                ----------------------------------------------------------------
                ----------------------------------------------------------------
                                 8. PERFORMANCE
                ----------------------------------------------------------------
                ----------------------------------------------------------------
 
   
The value of your contract will fluctuate depending upon the investment
performance of the variable portfolio(s) you choose.
    
 
   
When you invest in the Polaris Class A Variable Annuity, your money is actually
invested in the underlying portfolios of the Anchor Series Trust and/or the
SunAmerica Series Trust. These trusts are older than the annuity itself and have
served as underlying investments for other variable annuity contracts. Some of
the advertised historical performance for this annuity will be derived from the
performance of the corresponding portfolios of the trusts modified to reflect
the charges and expenses associated with this contract, as if this contract had
been in existence during the time period advertised. Of course, past performance
does not guarantee future results.
    
 
As of the date of this prospectus, the sale of this contract has not yet begun.
Therefore, no performance information is presented here.

                                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 Edward Jones investment
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 since that anniversary and
    less any withdrawals (and any fees or charges applicable to such
    withdrawals).
 
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.

                ----------------------------------------------------------------
                ----------------------------------------------------------------
 
   
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 sum of the value of your contract (unless otherwise required by state
law) and the sales charge. 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% IRS penalty tax may apply if you are under age 59 1/2.
 
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: You will receive a confirmation of each
transaction within your contract. On a quarterly basis, you will receive a
complete statement of your transactions over the past quarter and a summary of
your account values.

                INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE
- ----------------------------------------------------------------

Anchor National's Annual Report on Form 10-K for the year ended September 30,
1998, and its quarterly report on Form 10-Q for the quarter ended December 31,
1998 are incorporated herein by reference. In addition, Anchor National filed
two reports on Form 8-K on January 14 and 15, 1999. These reports are also
incorporated herein by reference.
 
All documents or reports filed by Anchor National pursuant to Section 13(a),
13(c), 14, or 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") after the date hereof and prior to the termination of the
offering of the securities offered hereby shall be deemed to be incorporated by
reference in this prospectus and to be a part hereof from the date of filing of
such documents. Any statement contained in a document incorporated or deemed to
be incorporated herein by reference shall be deemed to be modified or superseded
for purposes of this prospectus to the extent that a statement contained herein
or in any other subsequently filed document which also is or is deemed to be
incorporated by reference herein modifies or supersedes such statement. Any such
statement so modified or superseded shall not be deemed, except as so modified
and superseded, to constitute a part of this prospectus.
 
Anchor National files its Exchange Act documents and reports, including its
annual and quarterly reports on Form 10-K and Form 10-Q, electronically pursuant
to EDGAR under CIK No. 0000006342. The SEC maintains a web site that contains

         SECURITIES AND EXCHANGE COMMISSION POSITION ON INDEMNIFICATION
- ----------------------------------------------------------------
- ----------------------------------------------------------------
 
Insofar as indemnification for liabilities arising under the Securities Act of
1933 (the "Act") may be permitted to directors, officers, and controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that in the opinion of the SEC such indemnification
is against public policy as expressed in the Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer, or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

 ------------------------------------------------------------------
 We have capitalized some of the technical terms used in this
 prospectus. To help you understand these terms, we have defined
 them in this glossary.
 ACCUMULATION PHASE - The period during which you invest money in
 your contract.
 ACCUMULATION UNITS - A measurement we use to calculate the value
 of the variable portion of your contract during the Accumulation
 Phase.
 ANNUITANT(S) - The person(s) on whose life (lives) we base income
 payments.
 ANNUITY DATE - The date on which income payments are to begin, as
 selected by you.
 ANNUITY UNITS - A measurement we use to calculate the amount of
 income payments you receive from the variable portion of your
 contract during the Income Phase.
 BENEFICIARY - The person designated to receive any benefits under
 the contract if you or the Annuitant dies.
 GROSS PURCHASE PAYMENTS - The money you give us to buy the
 contract, as well as any additional money you give us to invest in
 the contract after you own it. Gross Purchase Payments do not
 reflect the reduction of the sales charge.
 INCOME PHASE - The period during which we make income payments to
 you.
 IRS - The Internal Revenue Service.
 NON-QUALIFIED (CONTRACT) - A contract purchased with after-tax
 dollars. In general, these contracts are not under any pension
 plan, specially sponsored program or individual retirement account
 ("IRA").
 PURCHASE PAYMENTS - The portion of your Gross Purchase Payments
 which we invest in your contract. We calculate this amount by
 deducting the applicable sales charge from your Gross Purchase
 Payments.
 QUALIFIED (CONTRACT) - A contract purchased with pre-tax dollars.
 These contracts are generally purchased under a pension plan,
 specially sponsored program or IRA.
 TRUSTS - Refers to the Anchor Series Trust and the SunAmerica

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

                      THE POLARIS CLASS A 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.
 
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
portfolios which, like mutual funds, vary with market conditions. 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 26 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.

We may refuse any Gross 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
 
   
A Purchase Payment is the portion of your Gross Purchase Payment which we invest
in your contract after we deduct the sales charge.
    
 
   
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 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, based on the AUV next
determined after receipt. 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 $50,000 Gross Purchase Payment from you on Wednesday which you
     allocate to the Global Bond Portfolio. After we deduct the sales charge,
     the net amount to be invested of your Gross Purchase Payment is $47,625. 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
     $47,625 by $11.10 and credit your contract on Wednesday night with 4290.54
     Accumulation Units for the Global Bond Portfolio.
    
 
Performance of the Variable Portfolios and the charges 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 the value of your
contract on the day we receive your request plus the sales charge we deducted.
The amount refunded may be more or less than the amount you originally invested.
    
 
   
Certain states require us to return your Gross Purchase Payments upon a free
look request. Additionally, all contracts issued as an IRA require the full
return of Gross 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 your Gross Purchase Payment or the value of your
contract plus the sales charge we deducted, whichever is larger. At the end of
the free look period, we allocate your money according to your instructions.

VARIABLE PORTFOLIOS
 
The contract currently offers 26 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 similarly 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 Trusts in this
manner disadvantages you. The adviser monitors the Trusts for potential
conflicts.

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, 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 one fixed account
       or one of the Variable Portfolios to another fixed account.
    
 
   
Each of these rates may differ from one another. Although once declared the
applicable rate is guaranteed until the 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 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
    
 
                                        8
<PAGE>   14
 
   
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 for a predetermined
amount of time. The interest rate in the
1-year or 6-month DCA fixed account is credited 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. 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 EDWARD JONES INVESTMENT REPRESENTATIVE FOR MORE INFORMATION.
 
If you take money out of the 3, 5, 7 or 10-year fixed account options before the
end of the guarantee period, we make an adjustment to your contract (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 annuitization occurs on the latest annuity date;
    
 
   
     - To pay a death benefit;
    
 
   
     - If made within 30 days after the end of a guarantee period; or
    
 
   
     - If made to pay contract charges.
    
 
   
The 1-year fixed account option and the DCA fixed accounts do not impose a MVA.
These fixed accounts are not registered under the Securities Act of 1933 and are
not subject to the provisions of the Investment Company Act of 1940.
    
 
APPENDIX A 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. 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, in the future you may be able to execute
transfers or other financial transactions over the internet. When receiving
instructions over the telephone, 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.
 
Upon implementation of internet account transfers we will have appropriate
procedures in place to provide reasonable assurance that the transactions
executed are genuine. Thus, we would not be responsible for any claim, loss or
expense from any error resulting from instructions received over the 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.

<PAGE>   15
 
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 15.
    
 
We reserve the right to modify, suspend, waive or terminate these transfer
provisions at any time.
 
DOLLAR COST AVERAGING
 
The 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. 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
 
                                       10
<PAGE>   16
 
     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 original allocations. The automatic asset
rebalancing program addresses this situation. At your election, we periodically
rebalance your investments 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.
    
 
You request quarterly, semiannual or annual rebalancing. 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 after we deduct sales charges. 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 Variable Portfolios become unavailable for investment, we may be required to
substitute shares of another Variable 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 15.)
    
 
   
We deduct a MVA if a partial withdrawal comes from the 3, 5, 7 or 10-year fixed
account prior to the end of the guarantee period. Additionally, a withdrawal
charge may apply in limited circumstances. If you withdraw your entire contract
value, we also deduct premium taxes if applicable. SEE EXPENSES ON PAGE 13.
    
 
   
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 19.
    
 
   
Under most circumstances, the partial withdrawal minimum is $1,000. We require
that the value left in any investment option be at least $500, 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(s) in which your contract is
invested.
    
 
We may be required to suspend or postpone the payment of a withdrawal for any
period of time when: (1) the NYSE is
 
                                       11
<PAGE>   17
 
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 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, semiannual or annual payments from your contract.
Electronic transfer of these funds to your bank account is available. The
minimum amount of each withdrawal is $250. 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 a MVA may apply.
SEE EXPENSES ON PAGE 13. We reserve the right to modify, suspend or terminate
this program at any time.
    
 
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 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 Edward Jones investment representative to determine 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 since 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 since 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 15.
    
 
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
 
                                       12
<PAGE>   18
 
     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 sales,
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 0.85% 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 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.
 
SALES CHARGE
 
   
We apply an up-front sales charge against each Gross Purchase Payment you put
into your contract. The sales charge equals a percentage of each Gross Purchase
Payment and varies with your investment amount according to the chart below.
    
 
   
Your investment amount at the time your Gross Purchase Payment is received is
determined by the sum of:
    
 
   
     1. Your current contract value for this contract;
    
 
   
     2. Your current Gross Purchase Payment amount;
    
 
   
     3. Any additional investment commitments secured by a Letter of Intent, as
        described below; and
    
 
   
     4. Your investment under Rights of Accumulation, as defined on the next
        page.

</TABLE>
    
 
   
* For investment amounts of $1,000,000 or more, we deduct from your contract
  value, a withdrawal charge of 0.50% for amounts withdrawn from a Purchase
  Payment invested less than 12 months prior to such withdrawal. SEE PURCHASE
  PAYMENTS SUBJECT TO A WITHDRAWAL CHARGE ON PAGE 14.
    
 
   
We call each investment amount a "breakpoint." You can reduce your sales charge
by increasing the amount of your investment amount to reach the next breakpoint.
For example, an investment amount of $50,000 brings you to the first breakpoint
and entitles you to a reduced sales charge of 4.75%.
    
 
REDUCTION OF SALES CHARGE
 
   
You may also be entitled to a reduced sales charge if you: (1) sign a Letter of
Intent to invest a combined amount of $50,000 or more within a 13-month period;
and/or (2) have related contracts with us which qualify for Rights of
Accumulation privileges.
    
 
LETTER OF INTENT
 
   
A Letter of Intent allows you to set your own investment goal of $50,000 or more
over a 13-month period. We base the sales charge on any Gross Purchase Payment
you make during the 13-month period on your investment goal. In essence, we
reduce your sales charge on Gross Purchase Payments made during the 13-month
period as though the total amount of Gross Purchase Payments (your investment
goal) is invested as one lump-sum.
    
 
     EXAMPLE:
 
   
     Assume as part of your contract application you sign a Letter of Intent
     indicating an investment goal of $50,000 over a 13-month period. The sales
     charge corresponding to your investment goal is 4.75%. You make an initial
     Gross Purchase Payment of $20,000. We deduct a reduced sales charge of
     4.75% from your initial Gross Purchase Payment. Two months later you make a
     subsequent Gross Purchase Payment of $10,000. We again deduct a reduced
     sales charge of 4.75% from your Gross Purchase Payment. Without a Letter of
     Intent the sales charge for each Gross Purchase Payment would have been
     5.75%.
    
 
                                       13
<PAGE>   19
 
   
You may elect to participate in the Letter of Intent program at any time.
However, we do not retroactively reduce sales charges on Gross Purchase Payments
made before we receive your Letter of Intent. If you choose to participate in
this program at the time you apply for the contract, you must check the
corresponding box on the application and complete the appropriate form. If you
elect to participate in the program after your contract is issued, you must
complete the Letter of Intent form, which is available from our Annuity Service
Center.
    
 
   
You are not obligated to reach your investment goal. If you do not achieve your
investment goal by the end of the 13-month period, we will deduct from your
contract the difference between (1) the sales charge applicable to the actual
amount of Gross Purchase Payments you invested during the period and (2) the
sales charge you actually paid. These charges will be deducted from your
contract at the end of the 13-month period.
    
 
If you exceed your investment goal and reach the next breakpoint, the sales
charge deducted is based on the next breakpoint level. However, we do not
retroactively reduce sales charges on previous Purchase Payments.
 
   
At any time during the 13-month period, you may increase your investment goal by
sending us a written request. Gross Purchase Payments made from the date of
notice through the end of the original 13-month period will receive any
applicable reduced sales charge. Sales charges on Gross Purchase Payments
received prior to the notice to increase your investment goal will not be
retroactively reduced.
    
 
We reserve the right to modify, suspend or terminate this program at any time.
 
RIGHTS OF ACCUMULATION
 
   
You may qualify for a reduced sales charge through Rights of Accumulation.
Rights of Accumulation involves combining your current Gross Purchase Payment
with your current contract value on this contract and/or the current contract
values of qualifying related contracts. If through accumulation you reach the
next breakpoint level, we reduce your sales charge accordingly.
    
 
   
Related contracts include other Anchor National contracts owned by you, your
spouse and your children under age 21. There may be other requirements for
qualification. For information on which related contracts qualify for Rights of
Accumulation privileges, please contact your Edward Jones investment
representative.
    
 
   
In order to use Rights of Accumulation to reduce your sales charge, you or your
Edward Jones investment representative must inform us in writing of the related
contracts. We will assign a Rights of Accumulation number to your contract.
Purchase Payments received after we assign a Rights of Accumulation number to
your contract will automatically qualify for a reduced sales charge, if
applicable.
    
 
   
If you choose to participate in this program at the time you apply for the
contract, you must check the corresponding box on the application and complete
the appropriate form. If you elect to participate in this program after your
contract is issued, you must complete the Rights of Accumulation form, which is
available from our Annuity Service Center.
    
 
   
The sales charge for Gross Purchase Payments submitted with a Rights of
Accumulation number will be based on the breakpoint corresponding to the sum of
(1) your Gross Purchase Payment; (2) your current contract value; and (3) the
current contract values of your related contracts.
    
 
     EXAMPLE:
 
   
     Assume your contract has a current value of $20,000. You have a second
     contract with us which qualifies for Rights of Accumulation that has a
     current value of $25,000. You make a $5,000 Gross Purchase Payment and
     include your Rights of Accumulation number with your payment. To determine
     the sales charge applicable to your Gross Purchase Payment we first
     calculate the sum of (1) your current contract value ($20,000); (2) the
     current contract value of your related contract ($25,000); and (3) your
     current Gross Purchase Payment ($5,000). The sum of these values is
     $50,000. We deduct the sales charge corresponding to a $50,000 Gross
     Purchase Payment, or 4.75%, from your $5,000 Gross Purchase Payment.
    
 
We reserve the right to modify, suspend or terminate this program at any time.
 
   
PURCHASE PAYMENTS SUBJECT TO A WITHDRAWAL CHARGE
    
 
   
For investment amounts of $1,000,000 or more, we deduct from your contract
value, a withdrawal charge of 0.50% for amounts withdrawn from a Purchase
Payment invested less than 12 months prior to such withdrawal.
    
 
   
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 fully surrender your contract value during the 12 months
following our receipt of a Purchase Payment on which we assessed a 0.50% sales
charge, we deduct the withdrawal charge 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
    
 
                                       14
<PAGE>   20
 
   
Income Phase, except when you elect to receive income payments using the Income
Protector program. If you elect to receive income payments using the Income
Protector program, we assess any applicable withdrawal charge applicable to
Purchase Payments remaining in your contract when calculating your Income
Benefit Base. SEE INCOME OPTIONS ON PAGE 15.
    
 
   
Withdrawals made prior to age 59 1/2 may result in a 10% IRS penalty tax. SEE
TAXES ON PAGE 19.
    
 
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.
    
 
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 B 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.

- ----------------------------------------------------------------
- ----------------------------------------------------------------
 
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 in which 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 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 19.
    
 
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.
 
                                       15
<PAGE>   21
 
     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 of 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, semi-annual 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 the 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 income 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
    
 
   
This feature provides a future "safety net" in the event that, when you choose
to begin receiving income payments, your contract has not performed within a
historically anticipated range. The income protector feature offers you the
ability to receive a guaranteed fixed minimum retirement income when you switch
to the Income Phase. With the income protector you can know the level of minimum
income that will be available to you if, when you chose to retire, down markets
have negatively impacted your contract value. To receive income payments using
this feature you must follow the appropriate steps set forth below.
    
 
   
The income protector provides three alternative levels of minimum retirement
income. The base income protector is a standard feature of your contract, if
available for sale in your state. There is no additional charge associated with
the base

feature. If elected, the income protector plus and income protector max
alternatives can provide increased levels of minimum guaranteed income. We
charge a fee for each of these alternatives. The amount of the fee and how to
select an alternative level of income protection, if that is appropriate for
you, is described below.
    
 
   
We reserve the right to modify, suspend or terminate the income protector
program 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 upon a calculation we call the income
benefit base. At the time your participation in the income protector program
becomes effective, your income benefit base is equal to your contract value. For
the base, participation is effective on the date of issue of your contract. For
the plus or max alternatives, participation is effective on either the date of
issue of the contract (if elected) or at the contract anniversary following your
election of the plus or max alternative.
    
 
   
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,
    
 
   
          - for the first year of calculation, your contract value on the date
            your participation in the program became effective, or;
    
 
   
          - for each subsequent year of calculation, the income benefit base on
            the prior contract anniversary, and;
    
 
   
     (b) is the sum of all subsequent Purchase Payments made into the contract
         since the last contract anniversary, and;
    
 
   
     (c) is 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.
    
 
   
For the plus or max alternatives, the income benefit base accumulates at one of
the following annual growth rates from the date your election in the alternative
becomes effective through your election to begin receiving income under the
program:

</TABLE>
    
 
   
* If you elect the plus or max feature on a subsequent anniversary, the Growth
  Rates may be different.
    
 
   
The growth rates for the plus or max features cease on the contract anniversary
following the Annuitant's 90th birthday.
    
 
   
CHOOSING THE APPROPRIATE LEVEL OF PROTECTION
    
   
FOR YOU
    
 
   
If you decide that you want the protection offered by the income protector plus
or max feature, you must elect the alternative by completing the income
protector election form available through our Annuity Service Center. You may
only elect one of the alternatives and you can never change your election once
made. Your income benefit base will begin accumulating at the applicable growth
rate on the contract anniversary following our receipt of your completed
election form. In order to obtain the benefit of the plus or max alternative you
may not begin the Income Phase for at least seven years following your election
of the plus or max feature. Thus, you must make your election prior to the later
of:
    
 
   
     - your 83rd birthday, or
    
 
   
     - your 3rd contract anniversary.
    
 
   
STEP-UP OF YOUR INCOME BENEFIT BASE
    
 
   
If you have elected to pay for the higher levels of protection available through
the income protector plus or max, you may also have the opportunity to "step-up"
your income benefit base. The step-up feature allows you to increase your income
benefit base to the amount of your contract value on your contract anniversary.
You can only elect to step-up within the 30 days before your next contract
anniversary. A seven year waiting period required prior to electing income
payments through the income protector is restarted if you step-up your income
benefit base. Thus, your last opportunity to step up is the later of:
    
 
   
     - your 83rd birthday, or
    
 
   
     - your 3rd contract anniversary.
    
 
   
You must complete the income protector election form to effect a step-up. The
form is available from our Annuity Service Center.
    
 
   
Qualified contract holders should refer to the Note at the end of the income
protector discussion.
    
 
   
ELECTING TO RECEIVE INCOME PAYMENTS
    
 
   
You may elect to begin the Income Phase of your contract using the income
protector program ONLY within the 30 days after the seventh or later contract
anniversary following the later of:
    
 
   
     - the effective date of your income protector participation, or
    
 
   
     - the contract anniversary of your most recent step-up.
    
 
                                       17
<PAGE>   23
 
   
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 your income benefit base as your income benefit date, and;
    
 
   
     (b) is 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
the annuity rates stated in your income protector endorsement for the income
option you select to your final income benefit base. 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 program 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
factors used to calculate your income under the income protector will be
different. You will receive whichever provides a greater stream of income. If
you elect to receive income payments using the income protector your income
payments will be fixed in amount. You are not required to use the income
protector to receive income payments. However, we will not refund fees paid for
the income protector if you elect to receive income payments under the general
provisions of your contract. YOU MAY NEVER NEED TO RELY UPON THE INCOME
PROTECTOR, IF YOUR CONTRACT PERFORMS WITHIN A HISTORICALLY ANTICIPATED RANGE.
HOWEVER, PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS.
    
 
   
FEES ASSOCIATED WITH THE INCOME PROTECTOR
    
 
   
The base income protector is a standard feature of your contract at no extra
charge. If you elect the income protector plus or max, we charge a fee, as
follows:
    
 
   
<TABLE>
<S>                        <C>
- -----------------------------------------------------
                           Fee As A % of Your Income
       Alternative                Benefit Base
- -----------------------------------------------------
The Income Protector Plus             .15%
- -----------------------------------------------------
 The Income Protector Max             .30%
- -----------------------------------------------------
</TABLE>
    
 
   
Since the income benefit base is only a calculation and does not provide a
contract value, we deduct the fee from your actual contract value beginning on
the contract anniversary on which your participation in the program becomes
effective.
    
 
   
After a step-up, the fee for the income protector max or plus will be based on
your stepped-up income benefit base, and will be deducted from your contract
value beginning on the effective date of the step-up.
    
 
   
If your contract is issued with the income protector program, and you elect the
plus or max alternative at some later date we begin deducting the annual fee for
the plus or max alternative on the contract anniversary when your alternative
election becomes effective. If your contract is not issued with the income
protector program and you elect the plus or max alternative at some later date,
we begin deducting the annual fee on the contract anniversary following the date
on which your participation in the program becomes effective.
    
 
   
It is important to note that once you elect either alternative, you may not
cancel your election. We will deduct this charge from your contract value on
every contract anniversary up to and including your income benefit date.
Additionally, we deduct the entire annual fee from any full surrender of your
contract requested prior to your contract anniversary.
    
 
   
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 the benefit of the income protector program. As discussed above, in
order to utilize the income protector you must elect to receive income payments
under one of two income options. If those income options exceed your life
expectancy you may be prohibited from receiving your guaranteed fixed income
under the program. If you own a Qualified contract to which this restriction
applies and you elect the income protector max or plus, you may pay for this
guarantee and not be able to realize the benefit.
    
 
   
Generally,
    
 
   
     - for the Life Annuity with 10 Years Guaranteed, you must elect to receive
       income payments before age 79, and
    
 
   
     - for the Joint and Survivor Life Annuity with 20 Years Guaranteed, both
       Annuitants must be 70 or younger or one of the Annuitants must be 65 or
       younger when you switch to the Income Phase. Other age combinations may
       be available.
    
 
   
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 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
 
                                       20
<PAGE>   25
 
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
 
If you have a Qualified contract, distributions must begin 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.
 
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 ("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.

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. 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
 
We rely significantly on computer systems and applications in our daily
operations. Many of our systems are not presently year 2000 compliant, which
means that because they have historically used only two digits to identify the
year in a date, they will fail to distinguish dates in the "2000s" from dates in
the "1900s." Anchor National's business, financial condition and results of
operations could be materially and adversely affected by the failure of our
systems and applications (and those operated by third parties interfacing with
our systems and applications) to properly operate or manage these dates.
 
   
Anchor National has a coordinated plan to repair or replace these noncompliant
systems and to obtain similar assurances from third parties interfacing with our
systems and applications. In fiscal 1997, the Company recorded a $6.2 million
provision for estimated programming costs to repair noncompliant systems. We are
making expenditures which we expect will ultimately total $5.0 million to
replace certain other noncompliant systems. Total expenditures relating to the
replacement of noncompliant systems will be capitalized by the Company as
software costs and will be amortized over future periods. Both phases of the
project are progressing according to plan and we expect to substantially
complete them by the end of calendar 1998. We will test both the repaired and
replacement systems during calendar 1999.
    
 
In addition, we distributed a year 2000 questionnaire to our significant
suppliers, distributors, financial institutions, lessors and others we do
business with to evaluate their year 2000 compliance plans and state of
readiness and to determine how our systems and applications may be affected by
their failure to solve their own year 2000 issues. To date, however, we have
only received preliminary feedback from such parties and have not independently
confirmed any information received from other parties with respect to the year
2000 issues. Therefore, we cannot assure that such other parties will complete
their year 2000 conversions in a timely fashion or will not suffer a year 2000
business disruption that may
 
                                       22
<PAGE>   27
 
adversely affect our financial condition and results of operations.
 
Because we expect to complete our year 2000 conversion prior to any potential
disruption to our business, we have not developed a comprehensive year 2000
contingency plan. Anchor National closely monitors the progression of its plan
for compliance, and if necessary, would devote additional resources to assure
the timely completion of our year 2000 plan. If we determine that our business
is at material risk of disruption due to the year 2000 issue or anticipate that
we will not complete our year 2000 conversion in a timely fashion, we will work
to enhance our contingency plans.
 
The above statements are forward-looking. The costs of our year 2000 conversion,
the date which we have set to complete such conversion and the possible risks
associated with the year 2000 issue are based on our current estimates and are
subject to various uncertainties that could cause the actual results to differ
materially from our expectations. Such uncertainties include, among others, our
success in identifying systems and applications that are not year 2000
compliant, the nature and amount of programming required to upgrade or replace
each of the affected systems and applications, the availability of qualified
personnel, consultants and other resources, and the success of the year 2000
conversion efforts of others.
 
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 Class A Variable Annuity is a Flexible Payment Group Deferred
Annuity contract. We issue a group contract to a contract holder for the benefit

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.

                  APPENDIX A - 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:
    
 
   
                                            (N/12)
                          [(1+I/(1+J+0.005)]       - 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 (net of the sales
         charge) 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.
    
 
   
We assume no withdrawal charge applies. 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%.
    
 
   
                                      (N/12)
The MVA factor is = [(1+I/(1+J+0.005)]       - 1
    
   
                                         (18/12)
                  = [(1.05)/(1.04+0.005)]        - 1
    
   
                              (1.5)
                  = (1.004785)      - 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%.
    
 
   
                                       (N/12)
The MVA factor is = [(1+I)/(1+J+0.005)]       - 1
    
   
                                         (18/12)
                  = [(1.05)/(1.06+0.005)]        - 1
    
   
                              (1.5)
                  = (0.985915)      - 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.

                             DISTRIBUTION AGREEMENT


         THIS AGREEMENT, entered into as of this 10thth day of February, 1999,
is between ANCHOR NATIONAL LIFE INSURANCE COMPANY ("Anchor"), a life insurance
company organized under the laws of the State of Arizona, on behalf of itself
and VARIABLE ANNUITY ACCOUNT SEVEN ("Separate Account"), a Separate Account

and SUNAMERICA CAPITAL SERVICES, INC. ("Distributor"), a corporation organized
under the laws of the State of Delaware.


                                   WITNESSETH:


         WHEREAS, Anchor issues to the public certain variable annuity contracts
identified on the contract specification sheet attached hereto as Attachment A
("Contracts"); and

         WHEREAS, Anchor, by resolution adopted on August 28, 1998, established
the Separate Account on its books of account, for the purpose of issuing

         WHEREAS, the Separate Account is registered with the Securities and
Exchange Commission ("Commission") as a unit investment trust under the
Investment Company Act of 1940 (File No. 811-09003); and

         WHEREAS, the Contracts to be issued by Anchor are registered with the
Commission under the Securities Act of 1933 (the "Act") (File No. 333-65965) for
offer and sale to the public, and otherwise are in compliance with all
applicable laws; and

         WHEREAS, the Distributor, a broker-dealer registered under the
Securities Exchange Act of 1934 and a member of the National Association of
Securities Dealers, Inc., proposes to act as distributor on an agency basis in
the marketing and distribution of the Contracts;

         WHEREAS, Anchor desires to obtain the services of the Distributor as

                  the Securities Exchange Act of 1934 and authorized by
                  applicable law to sell variable annuity contracts issued by
                  Anchor through the Separate Account. Any such contractual

                                    furnished to Anchor by the Distributor
                                    expressly for use therein, such Registration
                                    Statement and any amendments or supplements
                                    thereto will, when they become effective or
                                    are filed with the Commission, as the case

                                    the requirements of the Securities Act of
                                    1933 and the rules and regulations of the
                                    Commission thereunder and will not contain
                                    any untrue statement of a material fact or
                                    omit to state any material fact required to
                                    be stated therein or necessary to make the
                                    statements therein not misleading.

         5.       The Distributor,  or an affiliate thereof,  shall keep, or
                  cause  to be  kept,  in a  manner  and  form  prescribed  or
                  approved  by Anchor and in  accordance  with Rules 17a-3 and
                  17a-4 under the  Securities  Exchange  Act of 1934,  correct
                  records and books of account as required to be maintained by
                  a registered  broker-dealer,  acting as distributor,  of all
                  transactions  entered  into on  behalf  of  Anchor  and with
                  respect to its  activities  under this Agreement for Anchor.
                  The  party   maintaining  the  books  and  records  required
                  hereunder  shall  make such  records  and  books of  account
                  available for inspection by the Commission, and Anchor shall
                  have the right to inspect, make copies of or take possession
                  of such records and books of account at any time on demand.

         6.       Subsequent to having been authorized to commence the 
                  activities  contemplated  herein,  the  Distributor,  or  an
                  affiliate  thereof,   will  cause  the  currently  effective
                  Prospectus  relating to the subject  Contracts in connection
                  with its marketing and distribution  efforts to be utilized.
                  As to the other types of sales material, the Distributor, or
                  an affiliate  thereof,  agrees that it will cause to be used
                  only  sales  materials  as have been  authorized  for use by
                  Anchor and which conform to the  requirements of federal and
                  state laws and regulations,  and which have been filed where
                  necessary  with  the  appropriate  regulatory   authorities,
                  including the National  Association  of Securities  Dealers,
                  Inc.

         7.       The Distributor, or such other person as referred to in
                  paragraph 6 above, will not distribute any Prospectus, sales
                  literature, or any other printed matter or material in the
                  marketing and distribution of any Contract if, to the
                  knowledge of the Distributor, or such other person, any of the
                  foregoing misstates the duties, obligation or liabilities of
                  Anchor or the Distributor.

         8.       Expenses of providing sales presentations, mailings,
                  advertising and any other marketing efforts conducted in
                  connection with the distribution or sale of the Contracts
                  shall be borne by Anchor.

         9.       The Distributor, as distributor of the Contracts, shall not be
                  entitled to remuneration for its services.

         10.      All premium payments collected on the sale of the Contracts by
                  the Distributor, if any, shall be transmitted to Anchor for
                  immediate allocation to the Separate Account in accordance
                  with the directions furnished by the purchasers of such
                  Contracts at the time of purchase.

         11.      The Distributor makes no representations or warranties
                  regarding the number of Contracts to be sold by licensed
                  broker-dealers and insurance agents or the amount to be paid
                  thereunder. The Distributor does, however, represent that it
                  will actively engage in its duties under this Agreement on a
                  continuous basis while there is an effective registration
                  statement with the Commission.




                                      -4-

         12.      It is understood and agreed that the Distributor may render
                  similar services or act as a distributor or dealer in the
                  distribution of other variable contracts.

         13.      Anchor will use its best efforts to assure that the Contracts
                  are continuously registered under the Securities Act of 1933
                  and, should it ever be required, under state Blue Sky Laws and
                  to file for approval under state insurance laws when
                  necessary.

         14.      Anchor reserves the right at any time to suspend or limit the
                  public offering of the subject Contracts.

         15.      Anchor agrees to advise the Distributor immediately of:

                  (a)      any request by the Commission (i) for amendment of 
                           the Registration Statement relating to the Contracts,
                           or (ii) for additional information;

                  (b)      the issuance by the Commission of any stop order
                           suspending the effectiveness of the Registration
                           Statement relating to the Contracts or the initiation
                           of any proceedings for that purpose; and

                  (c)      the happening of any material event, if known, which
                           makes untrue any statement made in the Registration
                           Statement relating to the Contracts or which requires
                           the making of a change therein in order to make any
                           statement made therein not misleading.

         16.      Anchor will furnish to the Distributor such information with
                  respect to the Separate Account and the Contracts in such form
                  and signed by such of its officers as the Distributor may
                  reasonably request; and will warrant that the statements
                  therein contained when so signed will be true and correct.

         17.      Each of the undersigned parties agrees to notify the other in
                  writing upon being apprised of the institution of any
                  proceeding, investigation or hearing involving the offer or
                  sale of the subject Contracts.

         18.      This Agreement will terminate automatically upon its
                  assignment to any person other than a person which is a wholly
                  owned subsidiary of SunAmerica Inc. This Agreement shall
                  terminate, without the payment of any penalty by either party:

                  (a)      at the option of Anchor, upon sixty days' advance 
                           written notice to the Distributor; or

                  (b)      at the option of the Distributor upon 90 days' 
                           written notice to Anchor; or

                  (c)      at the option of Anchor upon institution of formal
                           proceedings against the Distributors by the National
                           Association of Securities Dealers, Inc. or by the
                           Commission; or

                  (d)      at the option of either party, if the other party or
                           any representative thereof at any time (i) employs
                           any device, scheme, or artifice to defraud; makes any
                           untrue statement of a material fact or omits to state
                           a material fact necessary in order to make the
                           statements made, in light of the circumstances under
                           which they were made, not misleading; or engages in
                           any act, practice, or course of business which
                           operates or would operate as a fraud or deceit upon
                           any person; or (ii) violates the conditions of this
                           Agreement.

         19.      Each notice required by this Agreement may be given by
                  telephone or telefax and confirmed in writing.

         20.      (a)      Anchor shall indemnify and hold harmless the
                           Distributor  and each  person,  if any, who controls
                           the Distributor  within the  meaning of the Act
                           against any losses,  claims,  damages  or
                           liabilities  to which the Distributor  or  such
                           controlling   person  may  become subject,  under the
                           Act or  otherwise,  insofar  as such losses,  claims,
                           damages or liabilities  (or actions in respect
                           thereof)  arise  out of or are  based  upon any
                           untrue  statement  or  alleged  untrue  statement  of
                           a material fact contained in the  Registration
                           Statement, Prospectus or Statement of Additional
                           Information or any other written sales material
                           prepared by Anchor which is utilized by the
                           Distributor in connection with the sale of  Contracts
                           or  arise  out of or are  based  upon the omission or
                           alleged omission to state therein a material fact
                           required to be stated  therein (in the case of the
                           Registration  Statement,  Prospectus  and  Statement
                           of Additional  Information),  or in the case of such
                           other sales material, necessary to make the
                           statements therein not misleading in the light of the
                           circumstances  under which they were made and will
                           reimburse the  Distributor and each such controlling
                           person for any legal or other expenses  reasonably
                           incurred by the Distributor or such controlling
                           person in connection with  investigating or defending
                           any such loss,  claim,  damage,  liability or action,
                           provided,  however,  that  Anchor  will  not be
                           liable  in any  such  case to the  extent  that any
                           such loss,  claim,  omission or alleged omission made
                           in such Registration  Statement,   Prospectus  or
                           Statement  of Additional Information is in conformity
                           with information furnished to Anchor  specifically
                           for use therein;  and provided,  further,  that
                           nothing  herein  shall  be so construed  as to
                           protect  the  Distributor  against  any liability to
                           Anchor or the Contract  Owners to which the
                           Distributor  would  otherwise  be  subject  by reason
                           of willful  misfeasance,  bad faith, or gross
                           negligence in the  performance  of his or her duties,
                           or by reason of his or her reckless  disregard by the
                           Distributor of its obligations and duties under this
                           Agreement.

                  (b)      The Distributor will likewise indemnify and hold
                           harmless Anchor, each of its directors and officers
                           and each person, if any, who controls the Trust
                           within the meaning of the Act to the extent, but only
                           to the extent, that such untrue statement or alleged
                           untrue statement or omission or alleged omission was
                           made in conformity with written information furnished
                           to the Trust by the Distributor specifically for use
                           therein.

         21.      This Agreement shall be subject to the laws of the State of
                  California and construed so as to interpret the Contracts and
                  insurance contracts written within the business operation of

                  regard to the distribution of the Contracts; except that this

                  agreements entered into between Anchor and the Distributor
                  unrelated to the sale of the Contracts.
