                           [POLARIS II PROFILE LOGO]
 
   
THIS PROFILE IS A SUMMARY OF SOME OF THE MORE IMPORTANT POINTS THAT YOU SHOULD
KNOW AND CONSIDER BEFORE PURCHASING THE POLARIS(II) VARIABLE ANNUITY. THE 
SECTIONS IN THIS PROFILE CORRESPOND TO SECTIONS IN THE ACCOMPANYING PROSPECTUS
WHICH DISCUSS THE TOPICS IN MORE DETAIL.  THE ANNUITY IS MORE FULLY DESCRIBED 
IN THE PROSPECTUS. PLEASE READ THE PROSPECTUS CAREFULLY.
 
                                 April 1, 1998
    
 
================================================================
                      1. THE POLARIS(II) VARIABLE ANNUITY
================================================================
 
The Polaris(II) Variable Annuity is a contract between you and Anchor National
Life Insurance Company. It is designed to help you invest on a tax-deferred
basis and meet long-term financial goals, such as retirement funding. Tax
deferral means all your money, including the amount you would otherwise pay in
current income taxes, remains in your contract to generate more earnings. Your
money could grow faster than it would in a comparable taxable investment.
 
   
Polaris(II) offers a diverse selection of money managers and investment options.
You may divide your money among any or all of our 26 variable investment
portfolios and 7 fixed investment options. Your investment is not guaranteed.
The value of your Polaris(II) contract can fluctuate up or down, based on the
performance of the underlying investments you select, and you may experience a
loss.
    
 
The variable investment 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 investment options, for different time periods
and each with a different interest rate that is 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 investment portfolios to
which your money is allocated and/or the interest rate earned on the fixed
investment options. 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
tax penalty may apply if you make withdrawals before age 59 1/2. During the
Income Phase, you will receive payments from your annuity. Your 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 determine the amount of your payments during the Income
Phase.
 
================================================================
                           2. ANNUITY INCOME OPTIONS
================================================================
 
You can select from one of five annuity 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 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 if you want your payments to fluctuate with
investment performance or remain constant, and the date on which your payments
will begin. Once you begin receiving payments, you cannot change your annuity
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
payment is taxable as income.
 
================================================================
                      3. PURCHASING A POLARIS(II) VARIABLE
                                ANNUITY CONTRACT
================================================================
 
You can buy a contract through your financial representative, who can also help
you complete the proper forms. For Non-qualified contracts, the minimum initial
investment 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 investment is $2,000 and subsequent amounts of $250 or more may
be added to your contract at any time during the Accumulation Phase.

financial representative for more information.) The interest rate may differ
from time to time but we will never credit less than a 3% annual effective rate.
Once established, the rate will not change during the selected period. Your
contract value will be adjusted up or down for withdrawals or transfers from the
3, 5, 7 and 10 year fixed investment options prior to the end of the selected

                ================================================================
                                  5. EXPENSES
                ================================================================
 
Each year, we deduct a $35 contract maintenance fee ($30 in North Dakota) from
your contract. This fee is currently waived if the value of your contract is at
least $50,000. We also deduct insurance charges which equal 1.52% annually of
the average daily value of your contract allocated to the variable portfolios.
The insurance charges include: Mortality and Expense Risk, 1.37%, and
Distribution Expense, .15%.
 
As with other professionally managed investments, there are also investment
charges imposed on contracts with money allocated to the variable portfolios,
which are estimated to range from .63% to 1.90%.
 
If you take money out in excess of the amount allowed for in your contract, you
may be assessed a withdrawal charge which is a percentage of the money you
withdraw. The percentage declines with each year the money is in the contract as
follows:

- -----------------------------------------------------------------------------------------------
</TABLE>
 
Each year, you are allowed to make 15 transfers without charge. After your first
15 free transfers, a $25 transfer fee ($10 in Pennsylvania and Texas) will apply
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 1.52%
insurance charges, the $35 contract maintenance fee and the investment charges
for each variable portfolio. We converted the contract maintenance fee to a
percentage using an assumed contract size of $40,000. The actual impact of this
charge on your contract may differ from this percentage.
 
The next two columns show two examples of the charges you would pay under the
contract. The examples assume that you invested $1,000 in a contract which earns
5% annually and that you withdraw your money: (1) at the end of year 1, and (2)
at the end of year 10. The premium tax is assumed to be 0% in both examples.

* For this Portfolio, the adviser, SunAmerica Asset Management Corp., has
  voluntarily agreed to waive fees or reimburse expenses, if necessary, to keep
  operating expenses at or below an established maximum amount. All waivers or
  reimbursements may be terminated at any time. For more detailed information,
  see the Fee Tables and Examples in the prospectus.
    
 
                ================================================================
                                    6. TAXES
                ================================================================
 
Unlike taxable investments where earnings are taxed in the year they are earned,
taxes on amounts earned in a Non-qualified contract (one that is established
with after tax dollars) are deferred until they are withdrawn. In a Qualified
contract (one that is established with before tax dollars like an IRA), 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 tax penalty for distributions or
withdrawals before age 59 1/2.
 
                ================================================================
                            7. ACCESS TO YOUR MONEY
                ================================================================
 
During the first year, you may withdraw free of a withdrawal charge an amount
that is equal to the penalty-free earnings in your contract as of the date you
make the withdrawal or, if you participate in the Systematic Withdrawal Program,
you may withdraw 10% of your total invested amount less any withdrawals made
during the year. The penalty-free earnings amount is calculated by taking the
value of your contract on the day you make the withdrawal and subtracting your
total invested amount. After the first year, your maximum free withdrawal amount
is the greater of: (1) the penalty-free earnings or (2) 10% of your total
invested amount that has been invested for at least one year, less any
withdrawals made during the year.
 
Withdrawals in excess of these limits will be assessed a withdrawal charge.
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.
 
If you withdraw your entire contract value, you will not receive the benefit of
any free withdrawal amount. After your money has been in the contract for seven
full years, there are no withdrawal charges on that portion of the money that
you have invested for at least seven full years. Of course, you may have to pay
income tax and a 10% IRS tax penalty may apply if you are under age 59 1/2.
Additionally, withdrawal charges are not assessed when a death benefit is paid.
 
                ================================================================
                                 8. PERFORMANCE
                ================================================================
 
The value of your annuity will fluctuate depending upon the investment
performance of the portfolio(s) you choose.
 
The following chart shows total returns for each portfolio for the time periods
shown. These numbers reflect the insurance charges, the contract maintenance fee
and the investment charges. Withdrawal charges are not reflected in the chart.
Past performance is no guarantee of future results.

                                9. DEATH BENEFIT
                ================================================================
 
If you should die during the Accumulation Phase, your beneficiary will receive a
death benefit. You must select from the two death benefit options described
below at the time you purchase your contract. Once selected, your death benefit
may not be changed. You should discuss with your financial representative the
options available to you and which option is best for you.
 
     OPTION 1 - PURCHASE PAYMENT ACCUMULATION OPTION:
 
The death benefit is the greater of:
 
(1) the value of your contract,
 
(2) the money you put in less any withdrawals, all compounded at 4% annually (3%
    if age 70 or older at time of issue), or
 
(3) the value of your contract on the seventh contract anniversary less any
    withdrawals plus any additional money you put in since the seventh
    anniversary, all compounded at 4% annually (3% if age 70 or older at time of
    issue).
 
     OPTION 2 - MAXIMUM ANNIVERSARY VALUE OPTION:
 
The death benefit is the greater of:
 
(1) the value of your contract,
 
(2) the money you put in less any withdrawals, or
 
(3) the maximum of the anniversary values up to your 81st birthday. The
    anniversary value is equal to the value of your contract on the contract
    anniversary less any withdrawals plus any additional money you put in since
    that anniversary.
 
If you are age 90 or older at the time of death, the death benefit under option
2 is the value of your contract.

                             10. OTHER INFORMATION
                ================================================================
 
FREE LOOK: You may cancel your contract within ten days (or longer if required
by your state) by mailing it to our Annuity Service Center. Your contract will
be treated as void on the date we receive it and we will pay you an amount equal
to the value of your contract (unless otherwise required by state law). Its
value may be more or less than the money you initially invested.
 
ASSET ALLOCATION REBALANCING: If selected by you, this program seeks to keep
your investment in line with your goals. We will maintain your specified
allocation mix in the variable investment portfolios and the 1-year fixed
investment 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 wired to
your bank account. Of course, withdrawals may be taxable and a 10% IRS tax
penalty 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 investment 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 equity and bond portfolios from any of the variable investment
portfolios, the 1-year fixed investment 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.

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 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 Portfolio's average net assets: SunAmerica Balanced and
    "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 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
    Portfolio is able to make such payment and remain in compliance with the
    foregoing expense limitations.
    
 
   
3.  Absent fee waivers or reimbursement of expenses by the adviser, you would
    have incurred the following expenses during the last fiscal year: SunAmerica
    Balanced (1.00%); Aggressive Growth (.90%); Federated Value (1.03%); Utility
    (1.24%); Emerging Markets (2.60%); International Growth and Income (2.02%);
    and Real Estate (1.36%).
    
 
   
4.  The Examples assume that no transfer fees were imposed. Although premium
    taxes may apply in certain states, they are not reflected in the Examples.
    
 
   
5.  THESE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
    
   
    
 
            THE HISTORICAL ACCUMULATION UNIT VALUES ARE CONTAINED IN
                 APPENDIX A -- CONDENSED FINANCIAL INFORMATION.
 
================================================================
                      1. THE POLARIS(II) VARIABLE ANNUITY
================================================================
 
An annuity is a contract between you, as the owner, and an insurance company.
The contract provides tax deferral for your earnings, as well as a death benefit
and a guaranteed income in the form of annuity payments beginning on a date you
select. Until you decide to begin receiving annuity payments, your annuity is in
the Accumulation Phase. Once you begin receiving annuity payments, your contract
switches to the Income Phase. If you die during the Accumulation Phase, the
insurance company guarantees a death benefit to your Beneficiary.
 
The Polaris(II) Variable Annuity Contract is issued by Anchor National Life
Insurance Company ("Anchor National"), a stock life insurance company organized
under the laws of the state of Arizona. Its principal business address is 1
SunAmerica Center, Los Angeles, California 90067-6022. Anchor National conducts
life insurance and annuity business in the District of Columbia and in all
states except New York. Anchor National is an indirect wholly owned subsidiary
of SunAmerica Inc., a Maryland corporation.
 
During the Accumulation Phase, the value of your annuity benefits from tax
deferral. This means your earnings accumulate on a tax-deferred basis until you
take money out of your contract. The Income Phase occurs if you decide to
receive annuity payments. You select the date on which annuity payments are to
begin.
 
The contract is called a variable annuity because you can choose among 26
variable investment Portfolios. Depending upon market conditions, you can make
or lose money in any of these Portfolios. If you allocate money to the
Portfolios, the amount of money you are able to accumulate in your contract
during the Accumulation Phase depends upon the investment performance of the
Portfolio(s) you select. The amount of the annuity payments you receive during
the Income Phase from the variable portion of your contract also depends upon
the investment performance of the Portfolios you select for the Income Phase.
 
   
The contract also contains 7 fixed investment options. Your money will earn
interest at the rate set by Anchor National. The interest rate is guaranteed by
Anchor National for the time you agree to leave your money in the fixed
investment option. We currently offer fixed investment options for 1, 3, 5, 7
and 10 year periods and DCA fixed account options for 6-month and 1-year
periods. (The 6-month DCA fixed account may not yet be available in your state.
Please contact your financial representative for more information. Please see
the subsection Dollar Cost Averaging Program under Section 4 Investment Options
for more information on the DCA fixed accounts.)
    
 
If you allocate money to the fixed investment options, the amount of money you
are able to accumulate in your contract during the Accumulation Phase depends
upon the total interest credited to your contract. An adjustment to your
contract will apply to withdrawals or transfers from the 3, 5, 7 and 10 year
fixed investment options prior to the end of the selected period. The amount of
annuity payments you receive during the Income Phase from the fixed portion of
your contract will remain level for the entire Income Phase.

================================================================
                           2. ANNUITY INCOME OPTIONS
================================================================
 
When you switch to the Income Phase, you will receive regular income payments
under the contract. Annuity payments will be made on a monthly, quarterly,
semiannual or annual basis. You can choose to have your annuity payments sent to
you by check or electronically wired to your bank.
 
You select the date on which annuity payments are to begin, which must be the
first day of a month and must be at least two years after the date your contract
is issued. We call this the Annuity Date. You may change your Annuity Date at
least seven days prior to the date that your payments are to begin. However,
annuity payments must begin by the later of your 90th birthday or ten years
after the date your contract is issued. If no Annuity Date is selected, annuity
payments will begin on the later of your 90th birthday or ten years after the
date your contract is issued. Certain states may require you to receive annuity
payments prior to such date. If the Annuity Date is past your 85th birthday, it
is possible that the contract would not be treated as an annuity and you may
incur adverse tax consequences.
 
The Annuitant is the person on whose life annuity payments are based. You may
change the Annuitant at any time prior to the Annuity Date if you are an
individual designated as the owner of the contract. You may also designate a
second person on whose life annuity payments are based. If the Annuitant dies
before the Annuity Date, you must notify us and designate a new Annuitant.
 
If you do not choose an annuity income option, annuity payments will be made in
accordance with option 4 (below) for 10 years. If the annuity payments are for
joint lives, then we will make payments in accordance with option 3. We may pay
the annuity in one lump sum if your contract is less than $5,000, where
permitted by state law. Likewise, if your annuity payments would be less than
$50 a month, we have the right to change the frequency of your payment to be on
a quarterly, semiannual or annual basis so that your annuity payments are at
least $50. Annuity payments will be made to you unless you designate another
person to receive them. In that case, you must notify us in writing at least
thirty days before the Annuity Date. You will remain fully responsible for any
taxes related to the annuity payments.
 
The contract offers 5 annuity income options. Other annuity income options may
be available in the future.
 
     OPTION 1 - LIFE INCOME
 
Under this option, we will make annuity payments as long as the Annuitant is
alive. Annuity payments stop when the Annuitant dies.
 
     OPTION 2 - JOINT AND SURVIVOR ANNUITY
 
Under this option, we will make annuity payments as long as the Annuitant and a
designated second person are alive. Upon the death of either person, we will
continue to make annuity payments so long as the survivor is alive. You choose
the amount of the annuity payments to the survivor, which can be equal to 100%,
66.66% or 50% of the full amount. Annuity payments stop upon the death of the
survivor.
 
     OPTION 3 - JOINT AND SURVIVOR LIFE ANNUITY WITH 10 YEARS GUARANTEED
 
This option is similar to option 2 above, with the additional guarantee that
payments will be made for at least 10 years. If the Annuitant and designated
second person die before all guaranteed payments have been made, the rest will
be made to the Beneficiary.
 
     OPTION 4 - LIFE ANNUITY WITH 10 OR 20 YEARS GUARANTEED
 
This option is similar to option 1 above, with the additional guarantee that
payments will be made for at least 10 or 20 years, as selected by you. Under
this option, if the Annuitant dies before all guaranteed payments have been
made, the rest will be made to the Beneficiary.
 
     OPTION 5 - INCOME FOR A SPECIFIED PERIOD
 
Under this option, we will make annuity payments for any period of time from 5
to 30 years, as selected by you. However, the period must be for full 12-month
periods. Under this option, if the Annuitant dies before all guaranteed payments
have been made, the rest will be made to the Beneficiary. This option does not
contain an element of mortality risk. Therefore, you will not get the benefit of
the mortality component of the mortality and expense risk charge if this option
is selected.
 
ALLOCATION OF ANNUITY PAYMENTS
 
On the Annuity Date, if your money is invested in the fixed investment options,
your annuity payments will be fixed in amount. If your money is invested in the
variable Portfolios, your annuity payments will vary depending on the investment
performance of the Portfolios. If you have money in the fixed and variable
investment options, your annuity payments will be based on the investment
allocations. You may not convert between fixed and variable payments once
annuity payments begin.
 
ANNUITY PAYMENTS
 
If you choose to have any portion of your annuity payments come from the
variable Portfolios, the dollar amount of your payment will depend upon three
things: (1) the value of your contract in the Portfolios on the Annuity Date,
(2) the 3.5% assumed investment rate used in the annuity table for the contract
and (3) the performance of the Portfolios you selected. If the actual
performance exceeds the 3.5% assumed rate, your annuity payments will increase.
Similarly, if the
 
                                        6
<PAGE>   13
 
actual rate is less than 3.5%, your annuity payments will decrease. The SAI
contains detailed information and sample calculations.
 
TRANSFERS DURING THE INCOME PHASE
 
Transfers are subject to the same limitations as transfers during the
Accumulation Phase. (See "Investment Options - Transfers During the Accumulation
Phase"). However, you can only make one transfer each month. You may not
transfer money from the fixed investment options to the variable Portfolios,
from the variable Portfolios to the fixed investment options or among the fixed
investment options during the Income Phase. You may transfer money among the
variable Portfolios.
 
DEFERMENT OF PAYMENTS
 
We may defer making fixed payments for up to six months, or less if required by
state law. Interest will be credited to you during the deferral period.

                          3. PURCHASING A POLARIS(II)
                                VARIABLE ANNUITY
================================================================
 
A Purchase Payment is 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. You can
purchase a Non-qualified contract with a minimum initial investment of $5,000
and a Qualified contract with a minimum initial investment of $2,000. The
maximum we accept is $1,000,000 without prior approval. Payments in amounts of
$500 or more may be added to your Non-qualified contract ($250 or more for
Qualified contracts) at any time during the Accumulation Phase. You can make
scheduled subsequent Purchase Payments of $20 or more per month by enrolling in
the Automatic Payment Plan.
 
We may refuse any Purchase Payment. In general, we will not issue a
Non-qualified contract to anyone who is over age 90 or a Qualified contract to
anyone who is age 70 1/2 or older unless you can show that the minimum
distributions required by the IRS are being made.
 
ALLOCATION OF PURCHASE PAYMENTS
 
When you purchase a contract, you will allocate your Purchase Payment to the
variable investment Portfolios and/or the fixed investment options. If you make
additional Purchase Payments, we will allocate them in the same way unless you
tell us otherwise.
 
Once we receive your Purchase Payment and a complete application at our
principal place of business, we will issue your contract and allocate your first
Purchase Payment within two business days. If you do not give us all the
necessary information, we will contact you to obtain it. If we are unable to
complete this process within five business days, we will either send back your
money or get your permission to keep it until we get all the necessary
information.
 
ACCUMULATION UNITS
 
The value of the variable portion of your contract will go up or down depending
upon the investment performance of the Portfolio(s) you choose. In order to keep
track of the value of your contract, we use a unit of measure called an
Accumulation Unit, which works like a share of a mutual fund. During the Income
Phase, we call them Annuity Units.
 
The value of an Accumulation Unit is determined each day that the New York Stock
Exchange ("NYSE") is open. We calculate an Accumulation Unit value for each
Portfolio after the NYSE closes each day. We do this by:
 
     (1) determining the total value of money invested in the particular
         Portfolio;
 
     (2) subtracting from that amount any insurance charges and any other
         charges such as taxes; and
 
     (3) dividing this amount by the number of outstanding Accumulation Units.
 
The value of an Accumulation Unit may go up or down from day to day. When you
make a Purchase Payment, we credit your contract with Accumulation Units. The
number of Accumulation Units credited is determined by dividing the amount of
the Purchase Payment allocated to a Portfolio by the value of the Accumulation
Unit for that Portfolio.
 
     EXAMPLE:
 
     We receive a $25,000 Purchase Payment from you on Wednesday. You want the
     money to go to the Global Bond Portfolio. We determine that the value of an
     Accumulation Unit for the Global Bond Portfolio is $11.10 when the NYSE
     closes on Wednesday. We then divide $25,000 by $11.10 and credit your
     contract on Wednesday night with 2252.252 Accumulation Units for the Global
     Bond Portfolio.
 
FREE LOOK
 
If you change your mind about owning this contract, you can cancel it within ten
days after receiving it (or longer if required by state law) by mailing it back
to our Annuity Service Center at P.O. Box 54299, Los Angeles, California
90054-0299. You will receive back whatever your contract is worth on the day we
receive your request. Its value may be more or less than the money you initially
invested. Thus, the investment risk is borne by you during the free look period.
 
In certain states or if you purchase your contract as
an IRA, we may be required to return your Purchase Payment. If that is the case,
we reserve the right to put your money in the Cash Management Portfolio during
the free look period. At the end of the period, we will reallocate your money as
you selected. If you cancel your contract during the free look period, we will
return to you the greater of your Purchase Payments or the value of your
contract.

FIXED INVESTMENT OPTIONS
 
   
The contract also offers 7 fixed investment options. We currently offer fixed
investment options for 1, 3, 5, 7, and 10 year periods and for contract owners
participating in the Dollar Cost Averaging Program, DCA fixed account options
for 6-month and 1-year periods. The fixed investment options offer interest
rates that are guaranteed by Anchor National. Interest rates may differ from
time to time due to changes in market conditions but we will never credit less
than a 3% annual effective rate. The interest rates offered for a specified
period for new Purchase Payments may differ from the interest rates offered for
money already in the fixed investment option. Once an interest rate is
established, it will not change during the specified period. The interest rates
are set at Anchor National's sole discretion.
    
 
If you have money allocated to the 1, 3, 5, 7 or 10 year fixed investment
options, you can renew for another 1, 3, 5, 7 or 10 year period or put your
money into one or more of the variable Portfolios after the end of the specified
period. Unless you specify otherwise before the end of the period, we will keep
your money in the fixed investment option for the same period you previously
selected. You will receive the interest rate then in effect.

The 6-month and 1-year DCA fixed accounts are available for initial or
subsequent purchase payments only.
    
 
   
The 1-year fixed investment option and the 6-month and 1-year DCA fixed accounts
are not registered under the Securities Act of 1933 and are not subject to other
provisions of the Investment Company Act of 1940.
    
 
MARKET VALUE ADJUSTMENT
 
   
NOTE: THE FOLLOWING DISCUSSION APPLIES TO THE 3, 5, 7 AND 10 YEAR FIXED
INVESTMENT OPTIONS ONLY. (THE 3, 5, 7 AND 10 YEAR FIXED INVESTMENT OPTIONS ARE
NOT AVAILABLE IN ALL STATES. PLEASE CONTACT YOUR FINANCIAL REPRESENTATIVE FOR
MORE INFORMATION.)
    
 
   
If you take your money out of the 3, 5, 7 or 10 year fixed investment option
(whether by withdrawal, transfer or annuitization) before the end of the
specified period, we will make an adjustment to the value of your contract. This
adjustment, called a "market value adjustment," can increase or decrease the
value of your contract. The market value adjustment reflects the differing
interest rate environments between the time you put your money into the fixed
investment option and the time you take your money out of the fixed investment
option.
    
 
We calculate the market value adjustment by comparing the interest rate you
received on the money you put into the fixed investment option against the
interest rate we are currently offering to contract owners for the period of
time remaining in the specified period. If we do not offer an interest rate for
that period, the interest rate will be determined by linear interpolation
between interest rates for the two nearest periods that are available.
 
Generally, if interest rates have dropped between the time you put your money
into the fixed investment option and the time you take it out, there will be a
positive adjustment to the value of your contract. Conversely, if interest rates
have increased between the time you put your money into the fixed investment
option and the time you take it out, there will be a negative adjustment to the
value of your contract.
 
If the market value adjustment is negative, it will be assessed first against
any money remaining in the fixed investment option and then against the money
you take out of the fixed investment option. If the market value adjustment is
positive, it will be added to the amount you take out of the fixed account.
 
Appendix B provides more information about how we calculate the market value
adjustment and gives some examples of the impact of the adjustment.
 
TRANSFERS DURING THE ACCUMULATION PHASE
 
You can transfer money among the Portfolios and the fixed investment options by
written request or by telephone. You can make 15 transfers every year without
charge. We measure a year from the anniversary of the day we issued your
contract. If you make more than 15 transfers in a year, there is a $25 transfer
fee for each transfer thereafter ($10 in Pennsylvania and Texas). Transfers
under Dollar Cost Averaging are included as part of your 15 free transfers each
year. However, transfers under Asset Allocation Rebalancing are not counted
against your 15 free transfers each year.
 
The minimum amount you can transfer is $100. You cannot make a partial transfer
if the value of the Portfolio from which the transfer is being made would be
less than $100 after the transfer. Your request for transfer must clearly state
which investment options are involved and the amount. We will accept transfers
by telephone unless you specify otherwise on your contract application. We have
in place procedures to provide reasonable assurance that instructions given to
us by telephone are genuine. Thus, we disclaim all liability for any claim, loss
or expense from any error. If we fail to use such procedures, we may be liable
for any losses due to unauthorized or fraudulent instructions.
 
We reserve the right to modify, suspend or terminate the transfer provisions at
any time. We also reserve the right to waive the $100 minimum amount for Dollar
Cost Averaging and Asset Allocation Rebalancing.
 
DOLLAR COST AVERAGING PROGRAM
 
The Dollar Cost Averaging Program allows you to systematically transfer a set
amount or percentage from one variable Portfolio or the 1-year fixed investment
option to any other variable Portfolio(s). You can also select to transfer the
entire value in a variable Portfolio or the 1-year fixed investment option in a
stated number of transfers. Transfers may be on a monthly or quarterly basis.
You can change the amount or frequency at any time by notifying us in writing.
The minimum amount that can be transferred is $100.
 
   
You may also set up dollar cost averaging using the 6-month or 1-year DCA fixed
accounts when you make either your initial Purchase Payment or a subsequent
Purchase Payment. You cannot transfer money from the variable Portfolio(s) or
fixed investment options into the DCA fixed accounts. If you allocate a Purchase
Payment to a DCA fixed account, all your money in that account will be
transferred into the variable Portfolio(s) over a 6-month or 1-year period,
depending on the option you select. You cannot change the option or frequency of
transfers. The minimum amount that can be transferred from a DCA fixed account
is $100.
    
 
   
If your money is allocated to the 6-month DCA fixed account, your money will be
transferred over a maximum of 6 monthly transfers. The actual number of
transfers from that account will be based on the amount allocated to the
account. For example, if you allocate $500 to the 6-month DCA fixed account,
your money will be transferred over a period of five months.
    
 
                                        9
<PAGE>   16
 
   
The number of transfers from the 1-year DCA fixed account will be determined
based on the amount or frequency of transfers selected and the amount allocated
to the 1-year DCA fixed account. You may select either monthly or quarterly
transfers. For example, if the 1-year DCA fixed account holds $1,000, and you
select monthly transfers, your money will be transferred over 10 months.
    
 
   
The interest rate offered for the 6-month and 1-year DCA fixed accounts may be
different from the interest rate offered to contract owners using the 1-year
fixed investment option for this program. If you terminate this program and are
dollar cost averaging from the DCA fixed accounts, any money remaining in the
DCA fixed accounts will be automatically transferred to the 1-year fixed
investment option and earn the interest rate then in effect unless you specify
another fixed or variable investment option.
    
 
   
By allocating amounts on a regular schedule as opposed to allocating the total
amount at one particular time, you may be less susceptible to the impact of
market fluctuations. However, there is no assurance that you will make a greater
profit. You are still subject to loss in a declining market. Dollar cost
averaging involves continuous investment in securities regardless of fluctuating
price levels. You should consider your financial ability to continue investing
through periods of fluctuating prices.
    
 
   
Transfers under the program are included as part of your 15 free transfers each
year. However, any transfers from the DCA fixed accounts upon termination of
this program will not be counted against your 15 free transfers. 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 the six
     quarters, while the average market price actually was $7.08. By investing
     an equal amount of money each month, you automatically buy more
     Accumulation Units when the market price is low and fewer Accumulation
     Units when the market price is high.
 
ASSET ALLOCATION REBALANCING PROGRAM
 
Once your money has been allocated among the investment options, the earnings
may cause the percentage invested in each investment option to differ from your
original percentage allocations. You can direct us to automatically rebalance
your contract to return to your original percentage allocations by selecting our
Asset Allocation Rebalancing Program. Rebalancing may be on a calendar quarter,
semiannual or annual basis. Rebalancing will occur on the last business day of
the month for the period you selected.
 
Transfers under the program are not counted against your 15 free transfers each
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
     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 allocate Purchase Payments to a
fixed investment option and one or more variable Portfolios without any market
risk to your principal. You decide how much you want to invest and when you
would like a return of your principal. We will calculate how much of your
Purchase Payment needs to be allocated to the 1, 3, 5, 7 or 10 year fixed
investment options to ensure that this money will grow to equal the full amount
of your Purchase Payment by the end of the selected period. The rest of your
Purchase Payment may then be divided among the variable Portfolios where it has
the potential to achieve greater growth.
 
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 investment
 
                                       10
<PAGE>   17
 
option. You want the amount allocated to the fixed investment option to grow to
$100,000 in 7 years. If the 7-year fixed investment option is offering a 7%
interest rate, we will allocate $62,275 to the 7-year fixed investment option to
ensure that this amount will grow to $100,000 at the end of the 7-year period.
The remaining $37,725 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
Portfolio solicits proxies in conjunction with a vote of shareholders, we are
required to obtain from you instructions as to how to vote those shares. When we
receive those instructions, we will vote all of the shares we own in proportion
to those instructions. This will also include any shares that we own on our
behalf. Should we determine that we are no longer required to comply with the
above, we will vote the shares in our own right.
 
SUBSTITUTION
 
If any of the Portfolios you selected are no longer available, we may be
required to substitute shares of another Portfolio. We will seek prior approval
of the SEC and give you notice before doing this.
================================================================
                                  5. EXPENSES
================================================================
 
There are charges and other expenses associated with the contract that will
reduce your investment return. These charges and expenses are described below.
 
INSURANCE CHARGES
 
Each day, we make a deduction for our insurance charges. This is done as part of
our calculation of the value of the Accumulation Units during the Accumulation
Phase and the Annuity Units during the Income Phase. The insurance charges
consist of the mortality and expense risk and the distribution expense charge.
 
     MORTALITY AND EXPENSE RISK CHARGE
 
This charge is equal, on an annual basis, to 1.37% of the daily value of the
contract invested in a Portfolio. This charge is for our obligation to make
annuity payments, to provide the death benefits and for assuming the risk that
the current charges will be insufficient in the future to cover the cost of
administering the contract.
 
If the charges under the contract are not sufficient, we will bear the loss. We
will not increase this charge. We may use any profits from this charge to pay
for the costs of distributing the contract.
     DISTRIBUTION EXPENSE CHARGE
 
This charge is equal, on an annual basis, to .15% of the daily value of the
contract invested in a Portfolio. This charge is for all expenses associated
with the distribution of the contract. These expenses include preparing the
contract, confirmations and statements, providing sales support, and maintaining
contract records. If this charge is not enough to cover the costs of
distributing the contract, we will bear the loss.
 
WITHDRAWAL CHARGES
 
Withdrawals in excess of your free withdrawal amount, as described in more
detail under "Access To Your Money," will be assessed a withdrawal charge. You
will not receive the benefit of any free withdrawal amount if you withdraw your
entire contract value.
 
We keep track of each Purchase Payment and assess a charge based on the length
of time a Purchase Payment is in your contract before it is withdrawn. After a
Purchase Payment has been in your contract for seven years, no withdrawal
charges are assessed on withdrawals of that Purchase Payment.
 
The withdrawal charge is assessed as a percentage of the Purchase Payment you
withdraw, which declines each year the Purchase Payment is in the contract as
follows:
 
<TABLE>
<CAPTION>
- -------------------------------------------------------------------
           Year               1    2    3    4    5    6    7   8+
- -------------------------------------------------------------------
<C>                          <S>  <C>  <C>  <C>  <C>  <C>  <C>  <C>
     WITHDRAWAL CHARGE       7%   6%   5%   4%   3%   2%   1%   0%
- -------------------------------------------------------------------
</TABLE>
 
If the withdrawal is for only part of the contract, we will deduct the
withdrawal charge from the remaining value in your contract. For purposes of
calculating the withdrawal charge, we treat withdrawals as coming from the
oldest Purchase Payment first. However, for tax purposes, earnings are
considered withdrawn first.
 
We will not assess a withdrawal charge for money withdrawn to pay a death
benefit or for annuity payments during the Income Phase.
 
INVESTMENT CHARGES
 
If you have money allocated to the variable Portfolios, there are deductions
from and expenses paid out of the assets of the various Portfolios. These
investment charges are summarized in the Fee Tables. For more detailed
information, you should refer to the prospectuses for the Anchor Series Trust
and the SunAmerica Series Trust.
 
CONTRACT MAINTENANCE FEE
 
During the Accumulation Phase, we will deduct a $35 contract maintenance fee
($30 in North Dakota) from your contract on each contract anniversary. This fee
is for expenses incurred to establish and maintain your contract. This fee
cannot be increased. If you make a complete
 
                                       11
<PAGE>   18
 
withdrawal from your contract, the entire contract maintenance fee will be
deducted prior to the withdrawal.
 
We will not deduct the contract maintenance fee if the value of your contract is
$50,000 or more when the deduction is to be made. We may discontinue this
practice at any time.
 
TRANSFER FEE
 
You can make 15 free transfers every year. We measure a year from the day we
issue your contract. If you make more than 15 transfers a year, we will deduct a
$25 transfer fee on each subsequent transfer ($10 in Pennsylvania and Texas).
 
PREMIUM TAXES
 
We are responsible for the payment of premium taxes, if any, charged by some
states and will make a deduction from your contract for them. These taxes are
due either when the contract is issued or when annuity payments begin. It is our
current practice not to charge you for these taxes until annuity payments begin
or a full surrender is made. In the future, we may discontinue this practice and
assess the tax when it is due or upon the payment of the death benefit.
 
Appendix B provides more information about the premium taxes assessed in each
state.
 
INCOME TAXES
 
Although we do not currently deduct any income taxes borne under your contract,
we reserve the right to do so in the future.
 
   
REDUCTION OR ELIMINATION OF CERTAIN CHARGES AND ADDITIONAL AMOUNTS CREDITED
    
 
   
We may reduce or eliminate the amount of certain insurance charges, credit
additional amounts or grant bonus guaranteed interest rates when the contract is
sold to groups of individuals under circumstances which reduce its sales
expenses. We will determine the eligibility of such groups by considering the
following factors: (1) the size of the group; (2) the total amount of Purchase
Payments we expect to receive from the group; (3) the nature of the purchase and
the persistency we expect in that group; (4) the purpose of the purchase and
whether that purpose makes it likely that expenses will be reduced; and (5) any
other circumstances which we believe to be relevant in determining whether
reduced sales expenses may be expected.
    
 
   
In addition, we may waive or reduce the contract maintenance fee, credit
additional amounts or grant bonus guaranteed interest rates in connection with
contracts sold to employees, employees of affiliates, registered
representatives, employees of broker-dealers which have a current selling
agreement with us ("Eligible Individuals") and immediate family members of all
Eligible Individuals when purchased directly through SunAmerica Capital
Services, Inc. Such reductions or waivers may be withdrawn or modified by us.
Commissions may be waived or reduced with respect to contracts established for
the personal accounts of Eligible Individuals.
    
 
================================================================
                                    6. TAXES
================================================================
 
NOTE: WE HAVE PREPARED THE FOLLOWING INFORMATION ON TAXES AS A GENERAL
DISCUSSION OF THE SUBJECT. IT IS NOT INTENDED AS TAX ADVICE. YOU ARE CAUTIONED
TO SEEK COMPETENT TAX ADVICE ABOUT YOUR OWN CIRCUMSTANCES. WE DO NOT GUARANTEE
THE TAX STATUS OF THE ANNUITY.
 
ANNUITY CONTRACTS IN GENERAL
 
   
The Internal Revenue Code ("IRC") provides for special rules regarding the tax
treatment of annuity contracts. From time to time, Federal initiatives are
proposed that could affect the tax treatment of insurance products. Recent
administration budget proposals include the proposed taxation of exchanges
involving variable annuity contracts, reallocations within variable annuity
contracts and certain other proposals relating to annuities. Please consult your
tax advisor for further information.
    
 
Generally, you will not be taxed on the earnings in your annuity contract until
you take the money out. 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, specially sponsored
program or an individual retirement account, your contract is referred to as a
Non-qualified contract and 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, specially sponsored program
or as an individual retirement account, your contract is referred to as a
Qualified contract. Examples of qualified plans are: Individual Retirement
Annuities ("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 annuity payments, any portion of each payment that is
 
                                       12
<PAGE>   19
 
considered a return of your Purchase Payment will not be taxed. Withdrawn
earnings are treated as income to you and are taxable. The IRC further provides
for a 10% tax penalty on any earnings that are withdrawn other than in
conjunction with the following circumstances: (1) after reaching age 59 1/2; (2)
by your Beneficiary after you die; (3) after you become disabled (as defined in
the IRC); (4) in a series of substantially equal installments made for your life
or for the joint lives of you and your Beneficiary; (5) 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 or on any earnings and therefore, any amount you take out as
a withdrawal or as annuity payments will be taxable income. The IRC further
provides for a 10% tax penalty on any withdrawal or annuitization paid to you
other than in conjunction with the following circumstances: (1) after reaching
age 59 1/2; (2) by your Beneficiary after you die; (3) after you become disabled
(as defined in the IRC); (4) in a series of substantially equal installments
made for your life or for the joint lives of you and your Beneficiary; (5) to
the extent such withdrawals do not exceed limitations set by the IRC for amounts
paid during the taxable year for medical care; (6) to fund higher education
expenses (as defined in the 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) 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) in the case of hardship. In the case of hardship, the owner can
only withdraw an amount equal to Purchase Payments and not any earnings.
 
DIVERSIFICATION
 
The IRC imposes certain diversification requirements on the underlying
investments for a variable annuity in order to be treated as a variable annuity
for tax purposes. We believe that the variable Portfolios are being managed so
as to comply with 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 Portfolios. It is unknown to what extent owners are
permitted to select investments, to make transfers among portfolios or the
number and type of 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 variable investment
Portfolios.
 
Due to the uncertainty in this area, we reserve the right to modify the contract
in an attempt to maintain favorable tax treatment.
 
================================================================
                            7. ACCESS TO YOUR MONEY
================================================================
 
Under your contract, money can be accessed in the following ways: (1) by making
a withdrawal, either for a part of the value of your contract or for the entire
value of your contract during the Accumulation Phase; (2) by receiving annuity
payments during the Income Phase; and (3) when a death benefit is paid to your
Beneficiary.
 
Generally, withdrawals are subject to a withdrawal charge, a market value
adjustment if the money is withdrawn from the 3, 5, 7 or 10 year fixed
investment options and, if you withdraw your entire contract value, premium
taxes and a contract maintenance fee. (See "Expenses" for more complete
information).
 
Your contract provides for a free withdrawal amount. For purposes of calculating
your free withdrawal amount, there are some special terms you should know and
understand how we define and calculate them.
 
Your "total invested amount" is equal to the sum of all your Purchase Payments
less any amounts previously withdrawn that incurred a withdrawal charge, and
less any Purchase Payments withdrawn that were no longer subject to the
withdrawal charge schedule. A "penalty-free earnings" amount is also calculated
by taking the value of your contract on the day you make the withdrawal and
subtracting your total invested amount. Any free withdrawals made in excess of
your penalty-free earnings will be considered a withdrawal of future
penalty-free earnings and therefore not a withdrawal of your total invested
amount.
 
During the first year, your free withdrawal amount is equal to the penalty-free
earnings in your contract as of the date you make the withdrawal or, if you
participate in the Systematic Withdrawal Program, you may withdraw 10% of your
total invested amount less any withdrawals made during the year. After the first
year, your maximum free withdrawal amount is the greater of: (1) the
penalty-free earnings or (2) 10% of your total invested amount that has been
invested for at least one year, less any withdrawals made during the year.
 
Although amounts withdrawn free of a withdrawal charge may reduce your
principal, they do not reduce your "total invested amount" for purposes of
calculating the withdrawal charge, the penalty-free earnings in your contract or
the free
 
                                       13
<PAGE>   20
 
withdrawal amount under the Systematic Withdrawal Program. As a result, you will
not receive the benefit of any free withdrawal amounts if you make a complete
withdrawal of your contract.
 
If you make a complete withdrawal, you will receive the value of your contract,
less any applicable fees and charges, as calculated on the day following receipt
by us at our principal place of business of a complete withdrawal request. Your
contract must be submitted as well.
 
Under most circumstances, partial withdrawals must be for a minimum of $1,000.
We require that the value left in any Portfolio or the fixed investment option
be at least $100 after the withdrawal. Unless you provide us with different
instructions, partial withdrawals will be made pro rata from each Portfolio and
the fixed investment option in which your contract is invested. You must send a
written withdrawal request to us prior to any withdrawal being made.
 
We may be required to suspend or postpone the payment of a withdrawal for any
period of time when: (1) the NYSE is closed (other than a customary weekend and
holiday closings); (2) trading on the NYSE is restricted; (3) an emergency
exists such that disposal of or determination of the value of shares of the
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 the
fixed investment option for the period permitted by law but not for more than
six months.
 
SYSTEMATIC WITHDRAWAL PROGRAM
 
This program allows you to receive either monthly, quarterly, semiannual or
annual checks during the Accumulation Phase. You can also choose to have
systematic withdrawals electronically wired to your bank account. The minimum
amount of each withdrawal is $250. Withdrawals may be taxable and a 10% IRS tax
penalty may apply if you are under age 59 1/2. There is no charge for
participating in this program.
 
This program is not available to everyone. Please check with our Annuity Service
Center, which can provide the necessary enrollment forms. We reserve the right
to modify, suspend or terminate this program at any time.
 
WITHDRAWAL CHARGES, MARKET VALUE ADJUSTMENTS, INCOME TAXES, TAX PENALTIES AND
CERTAIN RESTRICTIONS MAY APPLY TO ANY WITHDRAWAL YOU MAKE.
 
NURSING HOME WAIVER
 
If you are confined to a nursing home for 60 days or longer, we may waive the
withdrawal charge and/or market value adjustment on certain withdrawals prior to
the Annuity Date (not available in Texas). The waiver applies only to
withdrawals made while you are in a nursing home or within 90 days after you
leave the nursing home.
 
This waiver may not be used during the first 90 days after you purchase your
contract. In addition, the confinement period for which you seek the waiver must
begin after you purchase your contract.
 
In order to use this waiver, you must submit with your withdrawal request the
following documents: (1) a doctor's note recommending admittance to a nursing
home; (2) an admittance form which shows the type of facility you entered into
and (3) a bill from the nursing home which shows that the 60 day confinement
requirement has been met.
 
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) no Purchase Payments have been made during the past three years. We will
provide you with sixty days written notice and distribute the contract's
remaining value to you.
 
================================================================
                                 8. PERFORMANCE
================================================================
 
From time to time we may advertise the Cash Management Portfolio's yield and
effective yield. In addition, the other variable investment Portfolios may also
advertise total return, gross yield and yield to maturity information. These
figures are based on historical data and are not intended to indicate future
performance.
 
For periods starting prior to the date the contracts were first offered, the
performance will be derived from the performance of the corresponding portfolios
of the Trusts, modified to reflect Polaris(II) charges and expenses as if the
contracts had been in existence during the period stated in the advertisement.
Thus, these figures should not be construed to reflect actual historic
performance.
 
More detailed information on the method used to calculate performance for the
Portfolios is contained in the SAI.
 
The performance of each Portfolio may also be measured against unmanaged market
indices, including but 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, and may be compared 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").
 
At times Anchor National may also advertise the ratings and other information
assigned to it by independent rating
 
                                       14
<PAGE>   21
 
organizations such as A.M. Best Company ("A.M. Best"), Moody's Investors
Service, Inc. ("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/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 and do not measure the ability of such companies to meet other
non-policy obligations. The ratings also do not relate to the performance of the
Portfolios.
================================================================
                                9. DEATH BENEFIT
================================================================
 
If you should die during the Accumulation Phase of your contract, we will pay a
death benefit to your Beneficiary. You must select from the two death benefit
options described below at the time you purchase your contract. Once selected,
the death benefit option may not be changed. You should discuss with your
financial representative the options available to you and which option is best
for you.
 
    OPTION 1 - PURCHASE PAYMENT ACCUMULATION OPTION
 
The death benefit is the greater of:
 
(1) the value of your contract at the time we receive adequate proof of death,
 
(2) total Purchase Payments less any withdrawals, all compounded at 4% annually
    until the date of death (3% if age 70 or older at time of issue), or
 
(3) the value of your contract on the seventh contract anniversary less any
    withdrawals plus any additional Purchase Payments since the seventh
    anniversary, all compounded at 4% annually until the date of death (3% if
    age 70 or older at time of issue).
 
    OPTION 2 - MAXIMUM ANNIVERSARY VALUE OPTION
 
The death benefit is the greater of:
 
(1) the value of your contract at the time we receive adequate proof of death,
 
(2) total Purchase Payments less any withdrawals, or
 
(3) the maximum of the anniversary values up to your 81st birthday. The
    anniversary value is equal to the value of your contract on the contract
    anniversary less any withdrawals plus any additional Purchase Payments since
    that anniversary.
 
If you are age 90 or older at the time of death, the death benefit under option
2 is the value of your contract at the time we receive adequate proof of death.
 
In general, you would not get the advantage of the second option if you are over
age 80 at the time your contract is issued or age 90 or older at the time of
death.
 
The death benefit is not paid after you switch to the Income Phase. During the
Income Phase, your Beneficiary(ies) will receive any remaining guaranteed
annuity payments in accordance with the annuity option you choose.
 
You may select the Beneficiary(ies) to receive any amounts payable on death. You
may change the Beneficiary at any time, unless you previously made an
irrevocable Beneficiary designation. A new Beneficiary designation in not
effective until we record the change.
 
The death benefit is immediately payable under the contract. If the Beneficiary
elects an annuity option, it must be paid over the Beneficiary's lifetime or for
a period not extending beyond the Beneficiary's life expectancy. If the
Beneficiary is the spouse of the owner, he or she can elect to continue the
contract at the then current value, in which case he or she will not receive the
death benefit.
 
The death benefit will be paid out when we receive adequate proof of death: (1)
a certified copy of a death certificate; (2) a certified copy of a decree of
court of competent jurisdiction as to the finding of death; (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 also require additional
documentation or proof in order for the death benefit to be paid. If the
Beneficiary does not make a specific election within sixty days of our receipt
of such proof of death, the death benefit will be paid in a lump sum.

================================================================
 
ANCHOR NATIONAL
 
   
Anchor National is a stock life insurance company originally organized under the
laws of the state of California in April 1965. On January 1, 1996, Anchor
National redomesticated under the laws of the state of Arizona. Anchor National
is an indirect wholly owned subsidiary of SunAmerica, Inc., a Maryland
corporation. Anchor National is licensed to do business in the District of
Columbia and all states except New York.
    
 
   
Anchor National and its affiliates, SunAmerica Life Insurance Company, First
SunAmerica Life Insurance Company, CalAmerica Life Insurance Company, SunAmerica
National Life Insurance Company, SunAmerica Asset Management Corp., Imperial
Premium Finance, Inc., Resources Trust Company and four broker-dealers,
specialize in retirement savings and investment products and services, including
fixed and variable annuities, mutual funds, premium finance, broker-dealer and
trust administration services.
    
 
THE SEPARATE ACCOUNT
 
Anchor National originally established a separate account, Variable Separate
Account, under California law on June 25, 1981. We redomesticated under Arizona
law on January 1, 1996 and the separate account was assumed by Anchor National.
The separate account is registered with the SEC as a unit investment trust under
the Investment Company Act of 1940.
 
                                       15
<PAGE>   22
 
Anchor National owns the assets in the separate account. However, the assets in
the separate account are not chargeable with liabilities arising out of any
other business Anchor National may conduct. Income, gains and losses (realized
and unrealized) resulting from the assets in the separate account are credited
to or charged against the separate account without regard to other income, gains
or losses of Anchor National.
 
THE GENERAL ACCOUNT
 
If you put your money into the fixed investment options, it goes into Anchor
National's general account. The general account is made up of all of Anchor
National's assets other than assets attributable to a separate account. All of
the assets in the general account are chargeable with the claims of any Anchor
National contract owners as well as all creditors. The general account is
invested in assets permitted by state insurance law.
 
DISTRIBUTION
 
The contract is sold through registered representatives of broker-dealers.
Commissions are paid to registered representatives for the sale of contracts.
Commissions are not expected to exceed 7% of your Purchase Payment. Under some
circumstances, we may pay a persistency bonus in addition to standard
commissions. Usually the standard commission is lower when we pay a persistency
bonus, which is not anticipated to exceed 1.5% annually. Commissions paid to
registered representatives are not directly deducted from your Purchase Payment.
 
   
Furthermore, we may, from time to time, pay or allow additional promotional
incentives, in the form of cash or other compensation. In some instances, these
additional incentives may be offered only to certain broker-dealers that sell or
are expected to sell, during specified time periods, certain minimum amounts of
the contract, or other contracts offered by us.
    
 
   
SunAmerica Capital Services, Inc., 733 Third Avenue, 4th Floor, New York, New
York 10017 acts as the distributor of the contracts. SunAmerica Capital
Services, Inc., an affiliate of Anchor National, is registered as a
broker-dealer under the Exchange Act of 1934 and is a member of the National
Association of Securities Dealers, Inc.
    
 
ADMINISTRATION
 
We are responsible for all the administrative servicing of your contract. Please
contact Anchor National's Annuity Service Center at the telephone number and
address provided in the profile section of this prospectus if you have any
comment, question or service request.
 
We will send out transaction confirmations and quarterly statements. Please
review these documents carefully and notify us of any inaccuracies immediately.
We will investigate all questions and, to the extent we have made an error, we
will retroactively adjust your contract provided you have notified us within
thirty days of receiving the transaction confirmation or quarterly statement, as
applicable. All other adjustments will be made as of the time we receive notice
of the error.
 
   
Anchor National relies significantly on computer systems and applications in its
daily operations. Many of these systems and applications are not presently year
2000 compliant. Anchor National's business, financial condition and result of
operations could be materially and adversely affected by the failure of Anchor
National's systems and applications (and those operated by third parties
interfacing with Anchor National's systems and applications) to properly operate
or manage dates beyond the year 1999. Anchor National has a coordinated plan to
repair or replace these noncompliant systems and to obtain similar assurances
from third parties interfacing with Anchor National's systems and applications
and expects to significantly complete its plan by the end of calendar year 1998,
leaving 1999 for testing.
    
 
LEGAL PROCEEDINGS
 
There are no pending legal proceedings affecting the separate account. Anchor
National and its subsidiaries are engaged in various kinds of routine litigation
which, in management's judgment, are not of material importance to their
respective total assets or material with respect to the separate account.
 
OWNERSHIP
 
The Polaris(II) Variable Annuity is a Flexible Payment Group Deferred Annuity

participants in the group. You are a participant in the group and will receive a
certificate evidencing your ownership. You, as the owner of a certificate, are
entitled to all the rights and privileges of ownership. As used in this
prospectus, the term contract refers to your certificate. In some states a
Flexible Payment Individual Modified Guaranteed and Variable Deferred Annuity

described in this prospectus except that it is issued directly to the owner.
 
CUSTODIAN
 
State Street Bank and Trust Company, 225 Franklin Street, Boston, Massachusetts
02110, serves as the custodian of the assets of the separate account. Anchor
National pays State Street Bank for services based on a schedule of fees.

MANAGEMENT DISCUSSION AND ANALYSIS
 
Management's discussion and analysis of financial condition and results of
operations of Anchor National for the three years in the period ended September
30, 1997 follows. In connection with the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995, Anchor National cautions readers
regarding certain forward-looking statements contained in this report and in any
other statements made by, or on behalf of, Anchor National, whether or not in
future filings with the Securities and Exchange Commission (the "SEC").
Forward-looking statements are statements not based on historical information
and which relate to future operations, strategies, financial results, or other
developments. Statements using verbs such as "expect," "anticipate," "believe"
or words of similar import generally involve forward-looking statements. Without
limiting the foregoing, forward-looking statements include statements which
represent Anchor National's beliefs concerning future levels of sales and
redemptions of Anchor National's products, investment spreads and yields, or the
earnings and profitability of Anchor National's activities.
 
Forward-looking statements are necessarily based on estimates and assumptions
that are inherently subject to significant business, economic and competitive
uncertainties and contingencies, many of which are beyond Anchor National's
control and many of which are subject to change. These uncertainties and
contingencies could cause actual results to differ materially from those
expressed in any forward-looking statements made by, or on behalf of, Anchor
National. Whether or not actual results differ materially from forward-looking
statements may depend on numerous foreseeable and unforeseeable developments.
Some may be national in scope, such as general economic conditions, changes in
tax law and changes in interest rates. Some may be related to the insurance
industry generally, such as pricing competition, regulatory developments and
industry consolidation. Others may relate to Anchor National specifically, such
as credit, volatility and other risks associated with Anchor National's
investment portfolio. Investors are also directed to consider other risks and
uncertainties discussed in documents filed by Anchor National with the SEC.

RESULTS OF OPERATIONS FOR THE FISCAL YEARS 1995, 1996 AND 1997
 
NET INCOME totaled $63.1 million in 1997, compared with $45.1 million in 1996
and $39.3 million in 1995.
 
PRETAX INCOME totaled $94.3 million in 1997, $69.3 million in 1996 and $65.0
million in 1995. The 36.1% improvement in 1997 over 1996 primarily resulted from
increased fee income and net investment income, partially offset by higher
general and administrative expenses and increased amortization of deferred
acquisition costs. The 6.6% improvement in 1996 over 1995 primarily resulted
from increased net investment income and significantly increased fee income,
partially offset by increased net realized investment losses and additional
general and administrative expenses.
 
NET INVESTMENT INCOME, which is the spread between the income earned on invested
assets and the interest paid on fixed annuities and other interest-bearing
liabilities, increased to $73.2 million in 1997 from $56.8 million in 1996 and
$50.1 million in 1995. These amounts equal 2.77% on average invested assets
(computed on a daily basis) of $2.65 billion in 1997, 2.59% on average invested
assets of $2.19 billion in 1996 and 2.95% on average invested assets of $1.70
billion in 1995.
 
Net investment spreads include the effect of income earned on the excess of
average invested assets over average interest-bearing liabilities. This excess
amounted to $126.5 million in 1997, $142.9 million in 1996 and $108.4 million in
1995. The difference between Anchor National's yield on average invested assets
and the rate paid on average interest-bearing liabilities (the "Spread
Difference") was 2.51% in 1997, 2.25% in 1996 and 2.63% in 1995.
 
Investment income (and the related yields on average invested assets) totaled
$210.8 million (7.97%) in 1997, compared with $164.6 million (7.50%) in 1996 and
$129.5 million (7.62%) in 1995. These increased yields in 1997 include the
effects of a greater proportion of mortgage loans in Anchor National's
portfolio. On average, mortgage loans have higher yields than that of Anchor
National's overall portfolio. In addition, Anchor National experienced higher
returns on its investments in partnerships. The increases in investment income
in 1997 and 1996 also reflect increases in average invested assets.
 
Partnership income increased to $6.7 million (a yield of 15.28% on related
average assets of $44.0 million) in 1997, compared with $4.1 million (a yield of
10.12% on related average assets of $40.2 million) in 1996 and $5.1 million (a
yield of 10.60% on related average assets of $48.4 million) in 1995. Partnership
income is based upon cash distributions received from limited partnerships, the
operations of which Anchor National does not influence. Consequently, such
income is not predictable and there can be no assurance that Anchor National
will realize comparable levels of such income in the future.
 
Total interest expense equalled $137.6 million in 1997, $107.8 million in 1996
and $79.4 million in 1995. The average rate paid on all interest-bearing
liabilities was 5.46% in 1997, compared with 5.25% in 1996 and 4.99% in 1995.
Interest-bearing liabilities averaged $2.52 billion during 1997, compared with
$2.05 billion during 1996 and $1.59 billion during 1995.
 
The increases in the overall rates paid on interest-bearing liabilities during
1997 and 1996 primarily resulted from the impact of certain promotional one-year
interest rates offered
 
                                       19
<PAGE>   26
 
on the fixed account portion of Anchor National's Polaris variable annuity
product. The increase in the overall rates paid on all interest-bearing
liabilities during 1996 was also impacted by the growth in average reserves for
GICs, which generally bear higher rates of interest than fixed annuity
contracts. Average GIC reserves were $340.5 million in 1996 and $60.8 million in
1995. Most of Anchor National's GICs are variable rate and are repriced
quarterly at the then-current interest rates.
 
GROWTH IN AVERAGE INVESTED ASSETS since 1995 primarily reflects the sales of
Anchor National's fixed-rate products, consisting of both fixed annuity premiums
(including those for the fixed accounts of variable annuity products) and GIC
premiums. Fixed annuity premiums totaled $1.10 billion in 1997, compared with
$741.8 million in 1996 and $284.4 million in 1995. The premiums for the fixed
accounts of variable annuities have increased primarily because of increased
sales of Anchor National's Polaris product and greater inflows into the one-year
fixed account of that product. Anchor National has observed that many purchasers
of its variable annuity contracts allocate new premiums to the one-year fixed
account and concurrently elect the option to dollar cost average into one or
more variable funds. Accordingly, Anchor National anticipates that it will see a
large portion of these premiums transferred into the variable funds.
 
GIC premiums totaled $55.0 million in 1997, $135.0 million in 1996 and $275.0
million in 1995. GIC surrenders and maturities totaled $198.1 million in 1997,
$16.5 million in 1996 and $1.6 million in 1995. Anchor National does not
actively market GICs, so premiums may vary substantially from period to period.
The large increase in surrenders and maturities in 1997 was primarily due to
contracts maturing in 1997. The GICs issued by Anchor National generally
guarantee the payment of principal and interest at fixed or variable rates for a
term of three to five years. Contracts that are purchased by banks for their
long-term portfolios, or state and local governmental entities either prohibit
withdrawals or permit scheduled book value withdrawals subject to terms of the
underlying indenture or agreement. GICs purchased by asset management firms for
their short term portfolios either prohibit withdrawals or permit withdrawals
with notice ranging from 90 to 270 days. In pricing GICs, Anchor National
analyzes cash flow information and prices accordingly so that it is compensated
for possible withdrawals prior to maturity.
 
NET REALIZED INVESTMENT LOSSES totaled $17.4 million in 1997, $13.4 million in
1996 and $4.4 million in 1995. Net realized investment losses include impairment
writedowns of $20.4 million in 1997, $16.0 million in 1996 and $4.8 million in
1995. Therefore, net gains from sales of investments totaled $3.0 million in
1997, $2.6 million in 1996 and $0.4 million in 1995.
 
Anchor National sold invested assets, principally bonds and notes, aggregating
$2.19 billion, $1.28 billion and $1.15 billion in 1997, 1996 and 1995,
respectively. Sales of investments result from the active management of Anchor
National's investment portfolio. Because sales of investments are made in both
rising and falling interest rate environments, net gains from sales of
investments fluctuate from period to period, and represent 0.11%, 0.12% and
0.02% of average invested assets for 1997, 1996 and 1995, respectively. Active
portfolio management involves the ongoing evaluation of asset sectors,
individual securities within the investment portfolio and the reallocation of
investments from sectors that are perceived to be relatively overvalued to
sectors that are perceived to be relatively undervalued. The intent of Anchor
National's active portfolio management is to maximize total returns on the
investment portfolio, taking into account credit interest-rate risk.
 
Impairment writedowns reflect $15.7 million and $15.2 million of provisions
applied to non-income producing land owned in Arizona in 1997 and 1996,
respectively. The statutory carrying value of this land had been guaranteed by
Anchor National's ultimate Parent, SunAmerica Inc. ("SunAmerica"). SunAmerica
made capital contributions of $28.4 million and $27.4 million on December 31,
1996 and 1995, respectively, to Anchor National through Anchor National's direct
parent in exchange for the termination of its guaranty with respect to this
land. Accordingly, Anchor National reduced the carrying value of this land to
estimated fair value to reflect the full termination of the guaranty. Impairment
writedowns in 1995 include $3.8 million of additional provisions applied to
defaulted bonds. Impairment writedowns represent 0.77%, 0.73% and 0.28% of
average invested assets for 1997, 1996 and 1995, respectively. For the five
years ended September 30, 1997, impairment writedowns as a percentage of average
invested assets have ranged from 0.28% to 2.20% and have averaged 1.16%. Such
writedowns are based upon estimates of the net realizable value of the
applicable assets. Actual realization will be dependent upon future events.
 
VARIABLE ANNUITY FEES are based on the market value of assets in separate
accounts supporting variable annuity contracts. Such fees totaled $139.5 million
in 1997, $104.0 million in 1996 and $84.2 million in 1995. These increased fees
reflect growth in average variable annuity assets, principally due to the
receipt of variable annuity premiums, increased market values and net exchanges
into the separate accounts from the fixed accounts of variable annuity
contracts, partially offset by surrenders. Variable annuity assets averaged
$7.55 billion during 1997, $5.70 billion during 1996 and $4.65 billion during
1995. Variable annuity premiums, which exclude premiums allocated to the fixed
accounts of variable annuity products, totaled $1.27 billion in 1997, $919.8
million in 1996 and $577.2 million in 1995. Sales of variable annuity products
(which include premiums allocated to the fixed accounts) ("Variable Annuity
Product
 
                                       20
<PAGE>   27
 
Sales") amounted to $2.37 billion, $1.66 billion and $861.0 million in 1997,
1996 and 1995, respectively. Increases in Variable Annuity Product Sales are
due, in part, to market share gains through enhanced distribution efforts and
growing consumer demand for flexible retirement savings products that offer a
variety of equity, fixed income and guaranteed fixed account investment choices.
Anchor National has encountered increased competition in the variable annuity
marketplace during recent years and anticipates that the market will remain
highly competitive for the foreseeable future.
 
NET RETAINED COMMISSIONS are primarily derived from commissions on the sales of
nonproprietary investment products by Anchor National's broker-dealer
subsidiary, after deducting the substantial portion of such commissions that is
passed on to registered representatives. Net retained commissions totaled $39.1
million in 1997, $31.5 million in 1996 and $24.1 million in 1995. Broker-dealer
sales (mainly sales of general securities, mutual funds and annuities) totaled
$11.56 billion in 1997, $8.75 billion in 1996 and $5.67 billion in 1995. The
increases in sales and net retained commissions reflect a greater number of
registered representatives, due to Anchor National's ongoing recruitment of
representatives and to the transfer of representatives from an affiliated
broker-dealer, higher average production per representative and generally
favorable market conditions. Increases in net retained commissions may not be
proportionate to increases in sales primarily due to differences in sales mix.
 
SURRENDER CHARGES on fixed and variable annuities totaled $5.5 million in 1997,
compared with $5.2 million in 1996 and $5.9 million in 1995. Surrender charges
generally are assessed on annuity withdrawals at declining rates during the
first seven years of an annuity contract. Withdrawal payments, which include
surrenders and lump-sum annuity benefits, totaled $1.06 billion in 1997,
compared with $898.0 million in 1996 and $908.9 million in 1995. These payments
represent 11.22%, 12.44% and 15.06%, respectively, of average fixed and variable
annuity reserves. Withdrawals include variable annuity withdrawals from the
separate accounts totaling $822.0 million in 1997, $634.1 million in 1996 and
$632.1 million in 1995. Management anticipates that withdrawal rates will remain
relatively stable for the foreseeable future.
 
ASSET MANAGEMENT FEES, which include investment advisory fees and 12b-1
distribution fees, are based on the market value of assets managed in mutual
funds by SunAmerica Asset Management Corp. Such fees totaled $25.8 million on
average assets managed of $2.34 billion in 1997, $25.4 million on average assets
managed of $2.14 billion in 1996 and $26.9 million on average assets managed of
$2.07 billion in 1995. Asset management fees are not proportionate to average
assets managed, principally due to changes in product mix. Sales of mutual
funds, excluding sales of money market accounts, amounted to $454.8 million in
1997, compared with $223.4 million in 1996 and $140.2 million in 1995.
Redemptions of mutual funds, excluding redemptions of money market accounts,
amounted to $412.8 million in 1997, $379.9 million in 1996 and $426.5 million in
1995. The significant increases in sales during 1997 principally resulted from
the introduction in November 1996 of Anchor National's "Style Select Series"
product. Higher mutual fund sales and lower redemptions in 1996 both reflect
enhanced marketing efforts and the favorable performance records of certain of
Anchor National's mutual funds, and heightened consumer demand for equity
investments generally.
 
GENERAL AND ADMINISTRATIVE EXPENSES totaled $98.8 million in 1997, compared with
$81.6 million in 1996 and $65.3 million in 1995. General and administrative
expenses in 1997 include a $5.0 million provision for estimated programming
costs associated with the year 2000. Management believes that this provision is
adequate and does not anticipate any material future expenses associated with
this project. General and administrative expenses remain closely controlled
through a company-wide cost containment program and continue to represent less
than 1% of average total assets.
 
AMORTIZATION OF DEFERRED ACQUISITION COSTS totaled $66.9 million in 1997,
compared with $57.5 million in 1996 and $58.7 million in 1995. The increase in
amortization during 1997 was primarily due to additional fixed and variable
annuity sales and the subsequent amortization of related deferred commissions
and other direct selling costs. The decline in amortization for 1996 is due to
lower redemptions of mutual funds from the rate experienced in 1995, partially
offset by additional fixed and variable annuity and mutual fund sales in recent
years and the subsequent amortization of related deferred commissions and other
acquisition costs.
 
ANNUAL COMMISSIONS represent renewal commissions paid quarterly in arrears to
maintain the persistency of certain of Anchor National's variable annuity
contracts. Substantially all of Anchor National's currently available variable
annuity products allow for an annual commission payment option in return for a
lower immediate commission. Annual commissions totaled $9.0 million in 1997,
$4.6 million in 1996 and $2.7 million in 1995. The increase in annual
commissions since 1995 reflects increased sales of annuities that offer this
commission option. Anchor National estimates that approximately 45% of the
average balances of its variable annuity products is currently subject to such
annual commissions. Based on current sales, this percentage is expected to
increase in future periods.
 
INCOME TAX EXPENSE totaled $31.2 million in 1997, compared with $24.3 million in
1996 and $25.7 million in 1995, representing effective tax rates of 33% in 1997,
35% in 1996 and 40% in 1995. The higher effective tax rate in 1995 was due to a
prior year tax settlement. Without such payment, the effective tax rate would
have been 33%.

FINANCIAL CONDITION AND LIQUIDITY
 
SHAREHOLDER'S EQUITY increased 18.5% to $575.2 million at September 30, 1997
from $485.3 million at September 30, 1996, primarily due to $63.1 million of net
income recorded in 1997 and $18.4 million of net unrealized gains on debt and
equity securities available for sale (credited directly to shareholder's
equity), versus $5.5 million of net unrealized losses on such securities
recorded at September 30, 1996. In addition, Anchor National received a
contribution of capital of $28.4 million in December 1996 and paid a dividend of
$25.5 million in April 1997.
 
INVESTED ASSETS at year end totaled $2.61 billion in 1997, compared with $2.33
billion at year-end 1996. This 12.0% increase primarily resulted from sales of
fixed annuities and the $44.7 million net unrealized gain recorded on debt and
equity securities available for sale at September 30, 1997, versus the $12.7
million net unrealized loss recorded on such securities at September 30, 1996.
 
Anchor National manages most of its invested assets internally. Anchor
National's general investment philosophy is to hold fixed-rate assets for
long-term investment. Thus, it does not have a trading portfolio. However,
Anchor National has determined that all of its portfolio of bonds, notes and
redeemable preferred stocks (the "Bond Portfolio") is available to be sold in
response to changes in market interest rates, changes in relative value of asset
sectors and individual securities, changes in prepayment risk, changes in the
credit quality outlook for certain securities, Anchor National's need for
liquidity and other similar factors.
 
THE BOND PORTFOLIO, which comprises 76% of Anchor National's total investment
portfolio (at amortized cost), had an aggregate fair value that exceeded its
amortized cost by $43.7 million at September 30, 1997. At September 30, 1996,
the amortized cost exceeded the fair value of the Bond Portfolio by $13.8
million. The net unrealized gains on the Bond Portfolio since September 30, 1996
principally reflect the lower prevailing interest rates at September 30, 1997
and the corresponding effect on the fair value of the Bond Portfolio.
 
At September 30, 1997, the Bond Portfolio (at amortized cost, excluding $6.1
million of redeemable preferred stocks) included $1.82 billion of bonds rated by
Standard & Poor's Corporation ("S&P"), Moody's Investors Service ("Moody's"),
Duff & Phelps Credit Rating Co. ("DCR"), Fitch Investors Service, L.P. ("Fitch")
or the National Association of Insurance Commissioners ("NAIC"), and $124.4
million of bonds rated by Anchor National pursuant to statutory ratings
guidelines established by the NAIC. At September 30, 1997, approximately $1.72
billion of the Bond Portfolio was investment grade, including $650.3 million of
U.S. government/agency securities and mortgage-backed securities ("MBSs").
 
At September 30, 1997, the Bond Portfolio included $216.9 million (at amortized
cost with a fair value of $227.2 million) of bonds that were not investment
grade. Based on their September 30, 1997 amortized cost, these non-investment-
grade bonds accounted for 1.7% of Anchor National's total assets and 8.5% of its
invested assets.
 
Non-investment-grade securities generally provide higher yields and involve
greater risks than investment-grade securities because their issuers typically
are more highly leveraged and more vulnerable to adverse economic conditions
than investment-grade issuers. In addition, the trading market for these
securities is usually more limited than for investment-grade securities. Anchor
National had no material concentrations of non-investment-grade securities at
September 30, 1997. The following table summarizes Anchor National's rated bonds
by rating classification as of September 30, 1997.

(1) S&P and Fitch rate debt securities in rating categories ranging from AAA
    (the highest) to D (in payment default). A plus (+) or minus (-) indicates
    the debt's relative standing within the rating category. A security rated
    BBB- or higher is considered investment grade. Moody's rates debt securities
    in rating categories ranging from Aaa (the highest) to C (extremely poor
    prospects of ever attaining any real investment standing). The number 1, 2
    or 3 (with 1 the highest and 3 the lowest) indicates the debt's relative
    standing within the rating category. A security rated Baa3 or higher is
    considered investment grade. DCR rates debt securities in rating categories
    ranging from AAA (the highest) to DD (in payment default). A plus (+) or
    minus (-) indicates the debt's relative standing within the rating category.
    A security rated BBB- or higher is considered investment grade. Issues are
    categorized based on the highest of the S&P, Moody's, D&P and Fitch ratings
    if rated by multiple agencies.
(2) Bonds and short-term promissory instruments are divided into six quality
    categories for NAIC rating purposes, ranging from 1 (highest) to 5 (lowest)
    for nondefaulted bonds plus one category, 6, for bonds in or near default.
    These six categories correspond with the S&P/Moody's/DCR/Fitch rating groups
    listed above, with categories 1 and 2 considered investment grade. The NAIC
    categories include $124.4 million (at amortized cost) of assets that were
    rated by Anchor National pursuant to applicable NAIC rating guidelines.
(3) At amortized cost.
 
SENIOR SECURED LOANS ("Secured Loans") are included in the Bond Portfolio and
their amortized cost aggregated $329.3 million at September 30, 1997. Secured
Loans are senior to subordinated debt and equity, and are secured by assets of
the issuer. At September 30, 1997, Secured Loans consisted of loans to 80
borrowers spanning 28 industries, with 17% of these assets (at amortized cost)
concentrated in financial institutions. No other industry concentration
constituted more than 10% of these assets.
 
While the trading market for Secured Loans is more limited than for publicly
traded corporate debt issues, management believes that participation in these
transactions has enabled Anchor National to improve its investment yield. As a
result of restrictive financial covenants, Secured Loans involve greater risk of
technical default than do publicly traded investment-grade securities. However,
management believes that the risk of loss upon default for its Secured Loans is
mitigated by such financial covenants and the collateral values underlying the
Secured Loans. Anchor National's Secured Loans are rated by S&P, Moody's, DCR,
Fitch, the NAIC or by Anchor National, pursuant to comparable statutory ratings
guidelines established by the NAIC.
 
MORTGAGE LOANS aggregated $339.5 million at September 30, 1997 and consisted of
73 commercial first mortgage loans with an average loan balance of approximately
$4.7 million, collateralized by properties located in 21 states. Approximately
23% of this portfolio was multifamily residential, 18% was office, 14% was
 
                                       23
<PAGE>   30
 
manufactured housing, 13% was hotels, 11% was retail, 11% was industrial and 10%
was other types. At September 30, 1997, approximately 13% and 12% of this
portfolio was secured by properties located in New York and California,
respectively, and no more than 10% of this portfolio was secured by properties
located in any other single state. At September 30, 1997, there were four
mortgage loans with outstanding balances of $10 million or more, which loans
collectively aggregated approximately 17% of this portfolio. At the time of
their origination or purchase by Anchor National, virtually all mortgage loans
had loan-to-value ratios of 75% or less. At September 30, 1997, approximately
23% of the mortgage loan portfolio consisted of loans with balloon payments due
before October 1, 2000. During 1997, 1996 and 1995, loans delinquent by more
than 90 days, foreclosed loans and restructured loans have not been significant
in relation to the total mortgage loan portfolio.
 
At September 30, 1997, approximately 18% of the mortgage loans were seasoned
loans underwritten to Anchor National's standards and purchased at or near par
from other financial institutions. Such loans generally have higher average
interest rates than loans that could be originated today. The balance of the
mortgage loan portfolio has been originated by Anchor National under strict
underwriting standards. Commercial mortgage loans on properties such as offices,
hotels and shopping centers generally represent a higher level of risk than do
mortgage loans secured by multifamily residences. This greater risk is due to
several factors, including the larger size of such loans and the more immediate
effects of general economic conditions on these commercial property types.
However, due to the seasoned nature of Anchor National's mortgage loan
portfolio, its emphasis on multifamily loans and its strict underwriting
standards, Anchor National believes that it has prudently managed the risk
attributable to its mortgage loan portfolio while maintaining attractive yields.
 
OTHER INVESTED ASSETS aggregated $143.7 million at September 30, 1997, including
$46.9 million of investments in limited partnerships, $70.9 million of separate
account investments and an aggregate of $25.9 million of miscellaneous
investments, including policy loans, residuals and leveraged leases. Anchor
National's limited partnership interests, accounted for by using the cost method
of accounting, are invested primarily in a combination of debt and equity
securities.
 
ASSET-LIABILITY MATCHING is utilized by Anchor National to minimize the risks of
interest rate fluctuations and disintermediation. Anchor National believes that
its fixed-rate liabilities should be backed by a portfolio principally composed
of fixed-rate investments that generate predictable rates of return. Anchor
National does not have a specific target rate of return. Instead, its rates of
return vary over time depending on the current interest rate environment, the
slope of the yield curve, the spread at which fixed-rate investments are priced
over the yield curve, and general economic conditions. Its portfolio strategy is
constructed with a view to achieve adequate risk-adjusted returns consistent
with its investment objectives of effective asset-liability matching, liquidity
and safety. Anchor National's fixed-rate products incorporate surrender charges
or other restrictions in order to encourage persistency. Approximately 77% of
Anchor National's fixed annuity and GIC reserves had surrender penalties or
other restrictions at September 30, 1997.
 
As part of its asset-liability matching discipline, Anchor National conducts
detailed computer simulations that model its fixed-rate assets and liabilities
under commonly used stress-test interest rate scenarios. With the results of
these computer simulations, Anchor National can measure the potential gain or
loss in fair value of its interest-rate sensitive instruments and seek to
protect its economic value and achieve a predictable spread between what it
earns on its invested assets and what it pays on its liabilities by designing
its fixed-rate products and conducting its investment operations to closely
match the duration of the fixed-rate assets to that of its fixed-rate
liabilities. Anchor National's fixed-rate assets include: cash and short-term
investments; bonds, notes and redeemable preferred stocks; mortgage loans; and
investments in limited partnerships that invest primarily in fixed-rate
securities and are accounted for by using the cost method. At September 30,
1997, these assets had an aggregate fair value of $2.48 billion with a duration
of 3.4. Anchor National's fixed-rate liabilities include fixed annuities and
GICs. At September 30, 1997, these liabilities had an aggregate fair value
(determined by discounting future contractual cash flows by related market rates
of interest) of $2.32 billion with a duration of 1.3. Anchor National's
potential exposure due to a relative 10% increase in interest rates prevalent at
September 30, 1997 is a loss of approximately $31.2 million in fair value of its
fixed-rate assets that is not offset by an increase in the fair value of its
fixed-rate liabilities. Because Anchor National actively manages its assets and
liabilities and has strategies in place to minimize its exposure to loss as
interest rate changes occur, it expects that actual losses would be less than
the estimated potential loss.
 
Duration is a common option-adjusted measure for the price sensitivity of a
fixed-maturity portfolio to changes in interest rates. It measures the
approximate percentage change in the market value of a portfolio if interest
rates change by 100 basis points, recognizing the changes in cash flows
resulting from embedded options such as policy surrenders, investment
prepayments and bond calls. It also incorporates the assumption that Anchor
National will continue to utilize its existing strategies of pricing its fixed
annuity and GIC products, allocating its available cash flow amongst its various
investment portfolio sectors and maintaining sufficient levels of liquidity.
Because the calculation of duration involves estimation and incorporates
assumptions, potential changes in portfolio value indicated by the portfolio's
duration will likely
 
                                       24
<PAGE>   31
 
be different from the actual changes experienced under given interest rate
scenarios, and the differences may be material.
 
As a component of its asset and liability management strategy, Anchor National
utilizes interest rate swap agreements ("Swap Agreements") to match assets and
liabilities more closely. Swap Agreements are agreements to exchange with a
counterparty interest rate payments of differing character (for example,
variable-rate payments exchanged for fixed-rate payments) based on an underlying
principal balance (notional principal) to hedge against interest rate changes.
Anchor National currently utilizes Swap Agreements to create a hedge that
effectively converts fixed-rate liabilities into floating-rate instruments. At
September 30, 1997, Anchor National had one outstanding Swap Agreement with a
notional principal amount of $15.9 million. This agreement matures in December
2024.
 
Anchor National also seeks to provide liquidity from time to time by using
reverse repurchase agreements ("Reverse Repos") and by investing in MBSs. It
also seeks to enhance its spread income by using Reverse Repos. Reverse Repos
involve a sale of securities and an agreement to repurchase the same securities
at a later date at an agreed upon price and are generally over-collateralized.
MBSs are generally investment-grade securities collateralized by large pools of
mortgage loans. MBSs generally pay principal and interest monthly. The amount of
principal and interest payments may fluctuate as a result of prepayments of the
underlying mortgage loans.
 
There are risks associated with some of the techniques Anchor National uses to
provide liquidity, enhance its spread income and match its assets and
liabilities. The primary risk associated with Anchor National's Reverse Repos
and Swap Agreements is counterparty risk. Anchor National believes, however,
that the counterparties to its Reverse Repos and Swap Agreements are financially
responsible and that the counterparty risk associated with those transactions is
minimal. In addition to counterparty risk, Swap Agreements also have interest
rate risk. However, Anchor National's Swap Agreements typically hedge
variable-rate assets or liabilities, and interest rate fluctuations that
adversely affect the net cash received or paid under the terms of a Swap
Agreement would be offset by increased interest income earned on the
variable-rate assets or reduced interest expense paid on the variable-rate
liabilities. The primary risk associated with MBSs is that a changing interest
rate environment might cause prepayment of the underlying obligations at speeds
slower or faster than anticipated at the time of their purchase. As part of its
decision to purchase an MBS, Anchor National assesses the risk of prepayment by
analyzing the security's projected performance over an array of interest-rate
scenarios. Once an MBS is purchased, Anchor National monitors its actual
prepayment experience monthly to reassess the relative attractiveness of the
security with the intent to maximize total return.
 
INVESTED ASSETS EVALUATION routinely includes a review by Anchor National of its
portfolio of debt securities. Management identifies monthly those investments
that require additional monitoring and carefully reviews the carrying values of
such investments at least quarterly to determine whether specific investments
should be placed on a nonaccrual basis and to determine declines in value that
may be other than temporary. In making these reviews for bonds, management
principally considers the adequacy of any collateral, compliance with
contractual covenants, the borrower's recent financial performance, news reports
and other externally generated information concerning the creditor's affairs. In
the case of publicly traded bonds, management also considers market value
quotations, if available. For mortgage loans, management generally considers
information concerning the mortgaged property and, among other things, factors
impacting the current and expected payment status of the loan and, if available,
the current fair value of the underlying collateral.
 
The carrying values of bonds that are determined to have declines in value that
are other than temporary are reduced to net realizable value and no further
accruals of interest are made. The valuation allowances on mortgage loans are
based on losses expected by management to be realized on transfers of mortgage
loans to real estate, on the disposition and settlement of mortgage loans and on
mortgage loans that management believes may not be collectible in full. Accrual
of interest is suspended when principal and interest payments on mortgage loans
are past due more than 90 days.
 
DEFAULTED INVESTMENTS, comprising all investments that are in default as to the
payment of principal or interest, totaled $1.4 million at September 30, 1997 (at
amortized cost after impairment writedowns, with a fair value of $1.4 million),
including $0.5 million of bonds and notes and $0.9 million of mortgage loans. At
September 30, 1997, defaulted investments constituted 0.1% of total invested
assets. At September 30, 1996, defaulted investments totaled $3.1 million,
including $1.6 million of bonds and notes and $1.5 million of mortgage loans,
and constituted 0.1% of total invested assets.
 
SOURCES OF LIQUIDITY are readily available to Anchor National in the form of
Anchor National's existing portfolio of cash and short-term investments, Reverse
Repo capacity on invested assets and, if required, proceeds from invested asset
sales. At September 30, 1997, approximately $1.80 billion of Anchor National's
Bond Portfolio had an aggregate unrealized gain of $46.5 million, while
approximately $139.8 million of the Bond Portfolio had an aggregate unrealized
loss of $2.7 million. In addition, Anchor National's investment portfolio
currently provides approximately $22.5 million of monthly cash flow from
scheduled principal and interest payments. Historically, cash flows from
operations and from the sale of Anchor National's annuity and GIC products have
 
                                       25
<PAGE>   32
 
been more than sufficient in amount to satisfy Anchor National's liquidity
needs.
 
Management is aware that prevailing market interest rates may shift
significantly and has strategies in place to manage either an increase or
decrease in prevailing rates. In a rising interest rate environment, Anchor
National's average cost of funds would increase over time as it prices its new
and renewing annuities and GICs to maintain a generally competitive market rate.
Management would seek to place new funds in investments that were matched in
duration to, and higher yielding than, the liabilities assumed. Anchor National
believes that liquidity to fund withdrawals would be available through incoming
cash flow, the sale of short-term or floating-rate instruments or Reverse Repos
on Anchor National's substantial MBS segment of the Bond Portfolio, thereby
avoiding the sale of fixed-rate assets in an unfavorable bond market.
 
In a declining rate environment, Anchor National's cost of funds would decrease
over time, reflecting lower interest crediting rates on its fixed annuities and
GICs. Should increased liquidity be required for withdrawals, Anchor National
believes that a significant portion of its investments could be sold without
adverse consequences in light of the general strengthening that would be
expected in the bond market.
 
   
Anchor National relies significantly on computer systems and applications in its
daily operations. Many of these systems and applications are not presently year
2000 compliant. Anchor National's business, financial condition and results of
operations could be materially and adversely affected by the failure of Anchor
National's systems and applications (and those operated by third parties
interfacing with Anchor National's systems and applications) to properly operate
or manage dates beyond the year 1999. Anchor National has a coordinated plan to
repair or replace these noncompliant systems and to obtain similar assurances
from third parties interfacing with Anchor National's systems and applications
and expects to significantly complete its plan by the end of calendar year 1998.
In fiscal year 1997, Anchor National recorded a $5.0 million provision for
estimated programming costs to make necessary repairs of certain specific
noncompliant systems. Management believes that this provision is adequate and
does not anticipate any material future expenses associated with the repair
phase of this project. Management also expects to make an additional $6.2
million expenditure to replace certain other specific noncompliant systems,
which expenditure will be capitalized as software costs and amortized over
future periods.
    
 
   
RESULTS OF OPERATIONS FOR THE FIRST THREE MONTHS OF FISCAL 1998
    
 
   
NET INCOME totaled $44.3 million for the three months ended December 31, 1997
(the "First Quarter 1998"), compared with $3.3 million for the three months
ended December 31, 1996 (the "First Quarter 1997").
    
 
   
PRETAX INCOME totaled $67.7 million in the First Quarter 1998 and $4.9 million
in the First Quarter 1997. This significant increase in pretax income primarily
resulted from increased net realized investment gains, net investment income and
fee income.
    
 
   
NET INVESTMENT INCOME increased to $26.5 million in the First Quarter 1998 from
$14.5 million in the First Quarter 1997. These amounts equal 4.22% on average
invested assets (computed on a daily basis) of $2.51 billion in the First
Quarter 1998 and 2.32% on average invested assets of $2.50 billion in the First
Quarter 1997.
    
 
   
The excess of average invested assets over average interest-bearing liabilities
amounted to $72.6 million in the First Quarter 1998 and $150.5 million in the
First Quarter 1997. The Spread Difference was 4.06% in the First Quarter 1998
and 1.99% in the First Quarter 1997.
    
 
   
Investment income (and the related yields on average invested assets) totaled
$59.9 million (9.54%) in the First Quarter 1998, compared with $46.7 million
(7.46%) in the First Quarter 1997. Investment income and the related yields in
the First Quarter 1998 primarily reflect the higher returns realized on Anchor
National's investments in limited partnerships.
    
 
   
Partnership income increased to $15.2 million (for a yield of 400.95% on related
average assets of $15.1 million) in the First Quarter 1998, compared with $0.7
million (for a yield of 6.71% on related average assets of $44.6 million) in the
First Quarter 1997. Partnership income is based upon cash distributions received
from limited partnerships, the operations of which Anchor National does not
influence. Consequently, such income is not predictable and there can be no
assurance that Anchor National will realize comparable levels of such income in
the future.
    
 
   
Total interest expense equalled $33.4 million in the First Quarter 1998 and
$32.2 million in the First Quarter 1997. The average rate paid on all
interest-bearing liabilities was 5.48% in the First Quarter 1998, compared with
5.47% in the First Quarter 1997. Interest-bearing liabilities averaged $2.44
billion during the First Quarter 1998, compared with $2.35 billion during the
First Quarter 1997.
    
 
   
GIC premiums totaled $5.6 million in the First Quarter 1998 and $5.0 million in
the First Quarter 1997.
    
 
   
NET REALIZED INVESTMENT GAINS totaled $20.9 million in the First Quarter 1998,
compared with net realized investment losses of $19.1 million in the First
Quarter 1997. There were no impairment writedowns in the First Quarter 1998. Net
realized investment losses in the First Quarter 1997 include impairment
writedowns of $16.1 million. Therefore, Anchor National realized $3.0 million of
net losses from sales of investments in the First Quarter 1997.
    
 
                                       26
<PAGE>   33
 
   
Anchor National sold invested assets, principally bonds and notes, aggregating
$310.3 million and $741.6 million in the First Quarter 1998 and the First
Quarter 1997, respectively. Sales of investments result from the active
management of Anchor National's investment portfolio. Because sales of
investments are made in both rising and falling interest rate environments, net
gains and losses from sales of investments fluctuate from period to period, and
represent 1.70% and 0.48% of average invested assets for the First Quarter 1998
and the First Quarter 1997, respectively.
    
 
   
Impairment writedowns in the First Quarter 1997 reflect $15.7 million of
provisions applied to non-income producing land in Arizona. Impairment
writedowns, on an annualized basis, represent 2.58% of average invested assets
for the First Quarter 1997. For the seventeen fiscal quarters beginning October
1, 1993, impairment writedowns as a percentage of average invested assets have
ranged up to 3.64% and have averaged 0.45%.
    
 
   
VARIABLE ANNUITY FEES totaled $44.4 million in the First Quarter 1998 and $30.6
million in the First Quarter 1997. These increased fees reflect growth in
average variable annuity assets, principally due to the receipt of variable
annuity premiums, increased market values and net exchanges into the separate
accounts from the fixed accounts of variable annuity contracts, partially offset
by surrenders. Variable annuity assets averaged $9.40 billion during the First
Quarter 1998 and $6.60 billion during the First Quarter 1997. Variable annuity
premiums, which exclude premiums allocated to the fixed accounts of variable
annuity products, have aggregated $1.46 billion since December 31, 1996.
Variable annuity premiums increased to $422.1 million in the First Quarter 1998
from $226.8 million in the First Quarter 1997. Variable Annuity Product Sales
amounted to $684.0 million and $589.5 million in the First Quarter 1998 and the
First Quarter 1997, respectively. Increases in Variable Annuity Product Sales
are due, in part, to market share gains through enhanced distribution efforts
and growing consumer demand for flexible retirement savings products that offer
a variety of equity, fixed income and guaranteed fixed account investment
choices.
    
 
   
NET RETAINED COMMISSIONS totaled $10.5 million in the First Quarter 1998 and
$7.8 million in the First Quarter 1997. Broker-dealer sales totaled $3.83
billion in the First Quarter 1998 and $2.03 billion in the First Quarter 1997.
The increases in sales and net retained commissions reflect a greater number of
registered representatives, higher average production per representative and
generally favorable market conditions.
    
 
   
SURRENDER CHARGES on fixed and variable annuities totaled $1.3 million in the
First Quarter 1998, compared with $1.4 million in the First Quarter 1997.
Withdrawal payments totaled $268.5 million in the First Quarter 1998, compared
with $238.1 million in the First Quarter 1997. These payments represent, 9.4%
and 11.4%, respectively, of average fixed and variable annuity reserves.
Withdrawals include variable annuity withdrawals from the separate accounts
totaling $219.1 million in the First Quarter 1998 (9.4% of average variable
annuity reserves) and $176.0 million (10.7% of average variable annuity
reserves) in the First Quarter 1997. Approximately 77% of Anchor National's
fixed annuity and GIC reserves had surrender penalties or other restrictions at
December 31, 1997. Surrender charges have decreased in the First Quarter 1998,
while withdrawal payments have increased, due to policies coming off surrender
charge restrictions. Management anticipates that withdrawal rates will remain
relatively stable for the foreseeable future.
    
 
   
ASSET MANAGEMENT FEES totaled $6.9 million on average assets managed of $2.69
billion in the First Quarter 1998 and $6.4 million on average assets managed of
$2.21 billion in the First Quarter 1997. Sales of mutual funds, excluding sales
of money market accounts, have aggregated $558.3 million since December 31,
1996. Mutual fund sales totaled $165.8 million in the First Quarter 1998, up
166% from the $62.3 million in the First Quarter 1997. Redemptions of mutual
funds, excluding redemptions of money market accounts, amounted to $92.0 million
in the First Quarter 1998 and $103.7 million in the First Quarter 1997. The
significant increase in sales during the First Quarter 1998 over those in the
First Quarter 1997 principally resulted from the introduction in November 1996
of Anchor National's "Style Select Series" product.
    
 
   
GENERAL AND ADMINISTRATIVE EXPENSES totaled $23.0 million in the First Quarter
1998 and $22.4 million in the First Quarter 1997. General and administrative
expenses remain closely controlled through a company-wide cost containment
program and continue to represent less than 1% of average total assets.
    
 
   
AMORTIZATION OF DEFERRED ACQUISITION COSTS totaled $17.2 million in the First
Quarter 1998, compared with $13.8 million in the First Quarter 1997. The
increase in amortization during the First Quarter 1998 was primarily due to
additional fixed and variable annuity and mutual fund sales and the subsequent
amortization of related deferred commissions and other direct selling costs.
    
 
   
ANNUAL COMMISSIONS totaled $3.5 million in the First Quarter 1998 and $1.4
million in the First Quarter 1997. The increase in annual commissions reflects
increased sales of annuities that offer this commission option. Anchor National
estimates that approximately 50% of the average balances of its variable annuity
products is currently subject to such annual commissions. Based on current
sales, this percentage is expected to increase in future periods.
    
 
   
INCOME TAX EXPENSE totaled $23.3 million in the First Quarter 1998, compared
with $1.6 million in the First Quarter 1997, representing effective annualized
tax rates of 34% and 32%, respectively.

FINANCIAL CONDITION AND LIQUIDITY AT DECEMBER 31, 1997
    
 
   
SHAREHOLDER'S EQUITY increased 7.6% to $618.8 million at December 31, 1997 from
$575.2 million at September 30, 1997, primarily due to $44.3 million of net
income recorded in the First Quarter 1998.
    
 
   
INVESTED ASSETS at December 31, 1997 totaled $2.62 billion, compared with $2.61
billion at September 30, 1997.
    
 
   
THE BOND PORTFOLIO, which constitutes 74% of Anchor National's total investment
portfolio (at amortized cost), had an aggregate fair value that exceeded its
amortized cost by $43.0 million at December 31, 1997, compared with an excess of
$43.7 million at September 30, 1997.
    
 
   
At December 31, 1997, the Bond Portfolio (at amortized cost, excluding $6.1
million of redeemable preferred stocks) included $1.86 billion of bonds rated by
S&P, Moody's, DCR, Fitch or the NAIC and $51.2 million of bonds rated by Anchor
National pursuant to statutory ratings guidelines established by the NAIC. At
December 31, 1997, approximately $1.75 billion of the Bond Portfolio was
investment grade, including $614.7 million of U.S. government/agency securities
and MBSs.
    
 
   
At December 31, 1997, the Bond Portfolio included $162.0 million (at amortized
cost with a fair value of $170.4 million) of bonds that were not investment
grade. Based on their December 31, 1997 amortized cost, these non-
investment-grade bonds accounted for 1.3% of Anchor National's total assets and
6.3% of its invested assets. Anchor National had no material concentrations of
non-investment-grade securities at December 31, 1997.
    
 
   
SECURED LOANS are included in the Bond Portfolio and their amortized cost
aggregated $296.5 million at December 31, 1997. At December 31, 1997, Secured
Loans consisted of $168.2 million of publicly traded securities and $128.3
million of privately traded securities. These Secured Loans are composed of
loans to 80 borrowers spanning 25 industries, with 22% of these assets (at
amortized cost) concentrated in financial institutions. No other industry
concentration constituted more than 11% of these assets.
    
 
   
MORTGAGE LOANS aggregated $334.2 million at December 31, 1997 and consisted of
69 commercial first mortgage loans with an average loan balance of approximately
$4.8 million, collateralized by properties located in 20 states. Approximately
23% of this portfolio was multifamily residential, 17% was office, 15% was
manufactured housing, 13% was hotels, 11% was industrial, 11% was retail, and
10% was other types. At December 31, 1997, approximately 13% and 12% of this
portfolio was secured by properties located in New York and California,
respectively, and no more than 9% of this portfolio was secured by properties
located in any other single state. At December 31, 1997, there were four
mortgage loans with outstanding balances of $10 million or more, which loans
collectively aggregated approximately 17% of this portfolio. At December 31,
1997, approximately 22% of the mortgage loan portfolio consisted of loans with
balloon payments due before January 1, 2001. During the First Quarter 1998 and
the First Quarter 1997, loans delinquent by more than 90 days, foreclosed loans
and restructured loans have not been significant in relation to the total
mortgage loan portfolio.
    
 
   
At December 31, 1997, approximately 17% of the mortgage loans were seasoned
loans underwritten to Anchor National's standards and purchased at or near par
from other financial institutions.
    
 
   
OTHER INVESTED ASSETS aggregated $40.2 million at December 31, 1997, including
$14.3 million of investments in limited partnerships and an aggregate of $25.9
million of miscellaneous investments, including policy loans,residuals and
leveraged leases. Anchor National's limited partnership interests, accounted for
by using the cost method of accounting, are invested primarily in a combination
of debt and equity securities.
    
 
   
At December 31, 1997, Anchor National's fixed-rate assets had an aggregate fair
value of $2.51 billion with a duration of 3.8. Anchor National's fixed-rate
liabilities had an aggregate fair value (determined by discounting future
contractual cash flows by related market rates of interest) of $2.32 billion
with a duration of 1.4. Anchor National's potential exposure due to a relative
10% increase in interest rates prevalent at December 31, 1997 is a loss of
approximately $35.9 million in fair value of its fixed-rate assets that is not
offset by an increase in the fair value of its fixed-rate liabilities. Because
Anchor National actively manages its assets and liabilities and has strategies
in place to minimize its exposure to loss as interest rate changes occur, it
expects that actual losses would be less than the estimated potential loss.
    
 
   
At December 31, 1997, Anchor National had one outstanding Swap Agreement with a
notional principal amount of $15.9 million. This agreement matures in December
2024.

STATE REGULATION
 
Anchor National is subject to regulation and supervision by the insurance
regulatory agencies of the states in which it is authorized to transact
business. State insurance laws establish supervisory agencies with broad
administrative and supervisory powers. Principal among these powers are granting
and revoking licenses to transact business, regulating marketing and other trade
practices, operating guaranty associations, licensing agents, approving policy
forms, regulating certain premium rates, regulating insurance holding company
systems, establishing reserve requirements, prescribing the form and content of
required financial statements and reports, performing financial, market conduct
and other examinations, determining the reasonableness and adequacy of statutory
capital and surplus, defining acceptable accounting principles, regulating the
type, valuation and amount of investments permitted, and limiting the amount of
dividends that can be paid and the size of transactions that can be consummated
without first obtaining regulatory approval.
 
During the last decade, the insurance regulatory framework has been placed under
increased scrutiny by various states, the federal government and the NAIC.
Various states have considered or enacted legislation that changes, and in many
cases increases, the states' authority to regulate insurance companies.
Legislation has been introduced from time to time in Congress that could result
in the federal government assuming some role in the regulation of insurance
companies or allowing combinations between insurance companies, banks and other
entities. In recent years, the NAIC has approved and recommended to the states
for adoption and implementation several regulatory initiatives designed to
reduce the risk of insurance company insolvencies and market conduct violations.
These initiatives include investment reserve requirements, risk-based capital
standards, codification of insurance accounting principles, new investment
standards and restrictions on an insurance company's ability to pay dividends to
its stockholders. The NAIC is also currently developing model laws relating to
product design and illustrations for annuity products. Current proposals are
still being debated and Anchor National is monitoring developments in this area
and the effects any changes would have on Anchor National.

regulations and tax law changes affecting the taxation of insurance companies
and the tax treatment of insurance products. Recent administration budget
proposals include the proposed taxation of exchanges involving variable annuity
contracts and reallocations within variable annuity contracts and certain other
proposals relating to annuities. Anchor National believes these proposals have a
small likelihood of being enacted, because they would discourage retirement
savings and there is strong popular and industry opposition to them. Other
proposals made in recent years to limit the tax deferral of annuities have not
been enacted. Anchor National believes that certain of the proposals, if
implemented, would have an adverse effect on Anchor National's ability to sell
variable annuities, and, consequently, on its results of operations. However,
Anchor National would not expect this to materially impact earnings in the near
term because Anchor National believes that adoption of the administration
proposals, however unlikely, would reduce annuity surrenders on the existing
block of variable annuity contracts and the ongoing earnings potential arising
from that block would offset the near-term economic impact of the potential
decrease in sales.

The consolidated financial statements of Anchor National which are included in
this prospectus should be considered only as bearing on the ability Anchor
National to meet its obligations with respect to amounts allocated to the fixed
investment options and with respect to the death benefit and our assumption of
the mortality and expense risks and the risks that the withdrawal charge will
not be sufficient to cover the cost of distributing the contracts. They should
not be considered as bearing on the investment performance of the variable
Portfolios. The value of the variable Portfolios is affected primarily by the
performance of the underlying investments.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholder of
Anchor National Life Insurance Company
 
In our opinion, the accompanying consolidated balance sheet and the related
consolidated income statement and statement of cash flows present fairly, in all
material respects, the financial position of Anchor National Life Insurance
Company and its subsidiaries at September 30, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the period
ended September 30, 1997, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  NATURE OF OPERATIONS
 
Anchor National Life Insurance Company (the "Company") is a wholly owned
indirect subsidiary of SunAmerica, Inc. (the "Parent"). The Company is an
Arizona-domiciled life insurance company and conducts its business through three
segments: annuity operations, asset management and broker-dealer operations.
Annuity operations include the sale and administration of fixed and variable
annuities and guaranteed investment contracts. Asset management, which includes
the sale and management of mutual funds, is conducted by SunAmerica Asset
Management Corp. Broker-dealer operations include the sale of securities and
financial services products, and are conducted by Royal Alliance Associates,
Inc.
 
The operations of the Company are influenced by many factors, including general
economic conditions, monetary and fiscal policies of the federal government, and
policies of state and other regulatory authorities. The level of sales of the
Company's financial products is influenced by many factors, including general
market rates of interest; strength, weakness and volatility of equity markets;
and terms and conditions of competing financial products. The Company is exposed
to the typical risks normally associated with a portfolio of fixed-income
securities, namely interest rate, option, liquidity and credit risk. The Company
controls its exposure to these risks by, among other things, closely monitoring
and matching the duration of its assets and liabilities, monitoring and limiting
prepayment and extension risk in its portfolio, maintaining a large percentage
of its portfolio in highly liquid securities, and engaging in a disciplined
process of underwriting, reviewing and monitoring credit risk. The Company also
is exposed to market risk, as market volatility may result in reduced fee income
in the case of assets managed in mutual funds and held in separate accounts.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION:  The accompanying consolidated financial statements have
been prepared in accordance with generally accepted accounting principles and
include the accounts of the Company and all of its wholly owned subsidiaries.
All significant intercompany accounts and transactions are eliminated in
consolidation. Certain prior period amounts have been reclassified to conform
with the 1997 presentation.
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires the use of estimates and assumptions that affect
the amounts reported in the financial statements and the accompanying notes.
Actual results could differ from those estimates.
 
INVESTMENTS:  Cash and short-term investments primarily include cash, commercial
paper, money market investments, repurchase agreements and short-term bank
participations. All such investments are carried at cost plus accrued interest,
which approximates fair value, have maturities of three months or less and are
considered cash equivalents for purposes of reporting cash flows.
 
Bonds, notes and redeemable preferred stocks available for sale and common
stocks are carried at aggregate fair value and changes in unrealized gains or
losses, net of tax, are credited or charged directly to shareholder's equity.
Bonds, notes and redeemable preferred stocks are reduced to estimated net
realizable value when necessary for declines in value considered to be other
than temporary. Estimates of net realizable value are subjective and actual
realization will be dependent upon future events.
 
Mortgage loans are carried at amortized unpaid balances, net of provisions for
estimated losses. Real estate is carried at the lower of cost or fair value.
Other invested assets include investments in limited partnerships, which are
accounted for by using the cost method of accounting; separate account
investments; leveraged leases; policy loans, which are carried at unpaid
balances; and collateralized mortgage obligation residuals.
 
Realized gains and losses on the sale of investments are recognized in
operations at the date of sale and are determined using the specific cost
identification method. Premiums and discounts on investments are amortized to
investment income using the interest method over the contractual lives of the
investments.
 
INTEREST RATE SWAP AGREEMENTS:  The net differential to be paid or received on
interest rate swap agreements ("Swap Agreements") entered into to reduce the
impact of changes in interest rates is recognized over the lives of the
agreements, and such differential is classified as Interest Expense in the
income statement. All outstanding Swap Agreements are designated as hedges and,
therefore, are not marked to market. However, in the event that a hedged
asset/liability were to be sold or repaid before the related Swap Agreement
matures, the Swap Agreement would be marked to market and any gain/loss
classified with any gain/loss realized on the disposition of the hedged
asset/liability. Subsequently, the Swap
                                       38

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
Agreement would be marked to market and the resulting change in fair value would
be included in Investment Income in the income statement. In the event that a
Swap Agreement that is designated as a hedge were to be terminated before its
contractual maturity, any resulting gain/loss would be credited/charged to the
carrying value of the asset/liability that it hedged.
 
DEFERRED ACQUISITION COSTS:  Policy acquisition costs are deferred and
amortized, with interest, in relation to the incidence of estimated gross
profits to be realized over the estimated lives of the annuity contracts.
Estimated gross profits are composed of net interest income, net realized
investment gains and losses, variable annuity fees, surrender charges and direct
administrative expenses. Costs incurred to sell mutual funds are also deferred
and amortized over the estimated lives of the funds obtained. Deferred
acquisition costs consist of commissions and other costs that vary with, and are
primarily related to, the production or acquisition of new business.
 
As debt and equity securities available for sale are carried at aggregate fair
value, an adjustment is made to deferred acquisition costs equal to the change
in amortization that would have been recorded if such securities had been sold
at their stated aggregate fair value and the proceeds reinvested at current
yields. The change in this adjustment, net of tax, is included with the change
in net unrealized gains or losses on debt and equity securities available for
sale that is credited or charged directly to shareholder's equity. Deferred
Acquisition Costs have been decreased by $16,400,000 at September 30, 1997 and
increased by $4,200,000 at September 30, 1996 for this adjustment.
 
VARIABLE ANNUITY ASSETS AND LIABILITIES:  The assets and liabilities resulting
from the receipt of variable annuity premiums are segregated in separate
accounts. The Company receives administrative fees for managing the funds and
other fees for assuming mortality and certain expense risks. Such fees are
included in Variable Annuity Fees in the income statement.
 
GOODWILL:  Goodwill, amounting to $18,311,000 at September 30, 1997, is
amortized by using the straight-line method over periods averaging 25 years and
is included in Other Assets in the balance sheet. Goodwill is evaluated for
impairment when events or changes in economic conditions indicate that the
carrying amount may not be recoverable.
 
CONTRACTHOLDER RESERVES:  Contractholder reserves for fixed annuity contracts
and guaranteed investment contracts are accounted for as investment-type
contracts in accordance with Statement of Financial Accounting Standards No. 97,
"Accounting and Reporting by Insurance Enterprises for Certain Long-Duration
Contracts and for Realized Gains and Losses from the Sale of Investments," and
are recorded at accumulated value (premiums received, plus accrued interest,
less withdrawals and assessed fees).
 
FEE INCOME:  Variable annuity fees, asset management fees and surrender charges
are recorded in income as earned. Net retained commissions are recognized as
income on a trade-date basis.
 
INCOME TAXES:  The Company is included in the consolidated federal income tax
return of the Parent and files as a "life insurance company" under the
provisions of the Internal Revenue Code of 1986. Income taxes have been
calculated as if the Company filed a separate return. Deferred income tax assets
and liabilities are recognized based on the difference between financial
statement carrying amounts and income tax bases of assets and liabilities using
enacted income tax rates and laws.

Expenses incurred to manage the investment portfolio amounted to $2,050,000 for
the year ended September 30, 1997, $1,737,000 for the year ended September 30,
1996, and $1,983,000 for the year ended September 30, 1995 and are included in
General and Administrative Expenses in the income statement.
 
At September 30, 1997, no investment exceeded 10% of the Company's consolidated
shareholder's equity.
 
At September 30, 1997, mortgage loans were collateralized by properties located
in 21 states, with loans totaling approximately 13% of the aggregate carrying
value of the portfolio secured by properties located in New York and
approximately 12% by properties located in California. No more than 10% of the
portfolio was secured by properties in any other single state.
 
At September 30, 1997, bonds, notes and redeemable preferred stocks included
$216,877,000 (fair value of $227,169,000) of bonds and notes not rated
investment grade. The Company had no material concentrations of
non-investment-grade assets at September 30, 1997.
 
At September 30, 1997, the amortized cost of investments in default as to the
payment of principal or interest was $1,378,000, consisting of $500,000 of
non-investment-grade bonds and $878,000 of mortgage loans. Such nonperforming
investments had an estimated fair value of $1,378,000.
 
As a component of its asset and liability management strategy, the Company
utilizes Swap Agreements to match assets more closely to liabilities. Swap
Agreements are agreements to exchange with a counterparty interest rate payments
of differing character (for example, variable-rate payments exchanged for
fixed-rate payments) based on an underlying principal balance (notional
principal) to hedge against interest rate changes. The Company typically
utilizes Swap Agreements to create a hedge that effectively converts
floating-rate assets and liabilities to fixed-rate instruments. At September 30,
1997, the Company had one outstanding Swap Agreement with a notional principal
amount of $15.9 million, which matures in December, 2024. The net interest paid
amounted to $0.1 million for the year ended September 30, 1997, and is included
in Interest Expense on Guaranteed Investment Contracts in the income statement.
 
At September 30, 1997, $5,276,000 of bonds, at amortized cost, were on deposit
with regulatory authorities in accordance with statutory requirements.
 
4.  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
The following estimated fair value disclosures are limited to reasonable
estimates of the fair value of only the Company's financial instruments. The
disclosures do not address the value of the Company's recognized and
unrecognized nonfinancial assets (including its real estate investments and
other invested assets except for cost-method partnerships) and liabilities or
the value of anticipated future business. The Company does not plan to sell most
of its assets or settle most of its liabilities at these estimated fair values.
 
The fair value of a financial instrument is the amount at which the instrument
could be exchanged in a current transaction between willing parties, other than
in a forced or liquidation sale. Selling expenses and potential taxes are not
included. The

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
4.  FAIR VALUE OF FINANCIAL INSTRUMENTS -- (CONTINUED)
estimated fair value amounts were determined using available market information,
current pricing information and various valuation methodologies. If quoted
market prices were not readily available for a financial instrument, management
determined an estimated fair value. Accordingly, the estimates may not be
indicative of the amounts the financial instruments could be exchanged for in a
current or future market transaction.
 
The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate that
value:
 
CASH AND SHORT TERM INVESTMENTS:  Carrying value is considered to be a
reasonable estimate of fair value.
 
BONDS, NOTES AND REDEEMABLE PREFERRED STOCKS:  Fair value is based principally
on independent pricing services, broker quotes and other independent
information.
 
MORTGAGE LOANS:  Fair values are primarily determined by discounting future cash
flows to the present at current market rates, using expected prepayment rates.
 
COMMON STOCKS:  Fair value is based principally on independent pricing services,
broker quotes and other independent information.
 
COST-METHOD PARTNERSHIPS:  Fair value of limited partnerships accounted for by
using the cost method is based upon the fair value of the net assets of the
partnerships as determined by the general partners.
 
VARIABLE ANNUITY ASSETS:  Variable annuity assets are carried at the market
value of the underlying securities.
 
RECEIVABLE FROM (PAYABLE TO) BROKERS FOR SALES (PURCHASES) OF SECURITIES:  Such
obligations represent net transactions of a short-term nature for which the
carrying value is considered a reasonable estimate of fair value.
 
RESERVES FOR FIXED ANNUITY CONTRACTS:  Deferred annuity contracts and single
premium life contracts are assigned a fair value equal to current net surrender
value. Annuitized contracts are valued based on the present value of future cash
flows at current pricing rates.
 
RESERVES FOR GUARANTEED INVESTMENT CONTRACTS:  Fair value is based on the
present value of future cash flows at current pricing rates and is net of the
estimated fair value of hedging Swap Agreements, determined from independent
broker quotes.
 
VARIABLE ANNUITY LIABILITIES:  Fair values of contracts in the accumulation
phase are based on net surrender values. Fair values of contracts in the payout
phase are based on the present value of future cash flows at assumed investment
rates.

                      APPENDIX B - MARKET VALUE ADJUSTMENT
================================================================================
 
The market value adjustment 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 investment option, the greater the impact of changing interest rates.
The impact of the market value adjustment can be either positive or negative,
and is computed by multiplying the amount withdrawn, transferred or annuitized
by the following factor:
 
                          [(1+I/(1+J+0.005)](N/12) - 1
 
        The market value adjustment formula may differ in certain states
  where:
 
        I is the interest rate you are earning on the money invested in the
        fixed investment 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 investment option; and
 
        N is the number of full months remaining in the term you initially
        agreed to leave your money in the fixed investment option.
 
EXAMPLES OF THE MARKET VALUE ADJUSTMENT
 
The examples below assume the following:
 
     (1) You made an initial Purchase Payment of $10,000 and allocated it to the
         10-year fixed investment option at a rate of 7%;
 
     (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 investment option (N=18); and
 
     (3) You have not made any other transfers, additional Purchase Payments, or
         withdrawals.
 
No withdrawal charges are reflected because your Purchase Payment has been in
the contract for seven full years. If a withdrawal charge applies, it is
deducted before the market value adjustment. The market value adjustment is
assessed on the amount withdrawn less any withdrawal charges.
 
NEGATIVE ADJUSTMENT
 
Assume that on the date of withdrawal, the interest rate in effect for new
Purchase Payments in the 1-year fixed investment option is 7.5% and the 3-year
fixed investment option is 8.5%. 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 8%.
 
The market value adjustment factor is = [(1+I)/(1+J+0.005)](N/12) - 1
                                      = [(1.07)/(1.08+0.005)](18/12) - 1
                                      = (0.986175)(1.5) - 1
                                      = 0.979335 - 1
                                      = - 0.020665
 
The requested withdrawal amount is multiplied by the market value adjustment
factor to determine the market value adjustment:
                        $4,000 X (- 0.020665) = -$82.66
 
$82.66 represents the market value adjustment that will be deducted from the
money remaining in the 10-year fixed investment option.
 
POSITIVE ADJUSTMENT
 
Assume that on the date of withdrawal, the interest rate in effect for a new
Purchase Payments in the 1-year fixed investment option is 5.5% and the 3-year
fixed investment option is 6.5%. By linear interpolation, the interest rate for
the remaining 2 years (1 1/2 years rounded up to the next full year) in the
contract is calculated to be 6%.
 
The market value adjustment factor is = [(1+I/(1+J+0.005)](N/12) - 1
                                      = [(1.07)/(1.06+0.005)](18/12) - 1
                                      = (1.004695)(1.5) - 1
                                      = 1.007051 - 1
                                      = + 0.007051
 
The requested withdrawal amount is multiplied by the market value adjustment
factor to determine the market value adjustment:
                         $4,000 x (+0.007051) = +$28.20
 
$28.20 represents the market value adjustment that would be added to your
withdrawal.

Item 17.       Undertakings.

                The undersigned registrant, Anchor National Life Insurance
                Company, hereby undertakes:

        (1)     To file, during any period in which offers or sales are being
                made, a post-effective amendment to this registration statement:

                (i)     To include any prospectus required by Section 10(a)(3)
                        of the Securities Act of 1933;

                (ii)    To reflect in the prospectus any facts or events arising
                        after the effective date of the registration statement
                        (or the most recent post-effective amendment hereof)
                        which, individually or in the aggregate, represents a
                        fundamental change in the information in the
                        registration statement;

                (iii)   To include any material information with respect to the
                        plan of distribution not previously disclosed in the
                        registration statement or any material change to such
                        information in the registration statement;

        (2)     That, for the purpose of determining any liability under the
                Securities Act of 1933, each post-effective amendment shall be
                deemed to be a new registration statement relating to the
                securities offered therein, and the offering of such securities
                at that time shall be deemed to be the initial bona fide
                offering thereof; and

        (3)     To remove from registration by means of a post-effective
                amendment any of the securities being registered which remain
                unsold at the termination of the offering.

Contract, in accordance with the provisions set forth in this Certificate and in
consideration of the Participant Enrollment Form and Purchase Payments We

THE VALUE OF AMOUNTS ALLOCATED TO THE SEPARATE ACCOUNT DURING THE ACCUMULATION

THE INVESTMENT EXPERIENCE OF THE SUBACCOUNTS YOU CHOOSE.

THE CASH SURRENDER BENEFIT OF AMOUNTS ALLOCATED TO ANY FIXED-MVA ACCOUNT OPTION

THE UNADJUSTED CASH SURRENDER BENEFIT IS AVAILABLE FOR 30 DAYS AFTER THE END OF
THE GUARANTEE PERIOD. THERE IS NO MARKET VALUE ADJUSTMENT FOR ANY CASH SURRENDER
BENEFIT OF AMOUNTS ALLOCATED TO NON-MVA FIXED ACCOUNT OPTIONS.

RIGHT TO EXAMINE - YOU MAY RETURN THIS CERTIFICATE TO OUR ANNUITY SERVICE CENTER
OR TO THE AGENT THROUGH WHOM THE CERTIFICATE WAS PURCHASED WITHIN 10 DAYS AFTER
YOU RECEIVE IT, IF YOU ARE NOT SATISFIED WITH IT. THE COMPANY WILL REFUND THE
CERTIFICATE VALUE ON THE BUSINESS DAY DURING WHICH THE CERTIFICATE IS RECEIVED.
UPON SUCH REFUND, THE CERTIFICATE SHALL BE VOID.

For Individual Retirement Annuities, a refund of the Purchase Payment(s) may be
required. Therefore, We reserve the right to allocate your Purchase Payment(s)
to the Cash Management Subaccount until the end of the Right To Examine period.
Thereafter, allocations will be made as shown on the Certificate Data Page.

                             ACCUMULATION PROVISIONS

SEPARATE ACCOUNT ACCUMULATION VALUE

The Separate Account Accumulation Value under the Certificate shall be the sum
of the values of the Accumulation Units held in the Subaccounts for the
Participant.

NUMBER OF ACCUMULATION UNITS

For each Subaccount, the number of Accumulation Units is the sum of each
Purchase Payment and transfer amount allocated to the Subaccount, reduced by
premium taxes, if any:

Divided by

The Accumulation Unit value for that Subaccount for the NYSE business day in
which the Purchase Payment or transfer amount is received.

The number of Accumulation Units will be similarly adjusted for withdrawals,
annuitizations, transfers and charges. Adjustments will be made as of the NYSE
business day in which We receive all requirements for the transaction, as
appropriate.

ACCUMULATION UNIT VALUE (AUV)

The AUV of a Subaccount for any NYSE business day is calculated by subtracting
(2) from (1) and dividing the result by (3) where:

(1)     is the total value for the given NYSE business day of the assets
        attributable to the Accumulation Units of the Subaccount minus the total
        liabilities;

(2)     is the cumulative unpaid charge for assumption of Expense Risk,
        Distribution Expense, Mortality Risk and Guaranteed Death Benefit Risk
        charges (See CHARGES AND DEDUCTIONS);

(3)     is the number of Accumulation Units outstanding at the end of the given
        NYSE business day.

FIXED ACCOUNT ACCUMULATION VALUE

Under the Certificate, the Fixed Account Accumulation Value shall be the sum of
all monies allocated or transferred to the Fixed Account Option(s), reduced by
any applicable premium taxes, plus all interest credited on the Fixed Account
Option(s) during the period that the Certificate has been in effect. This amount
shall be adjusted for withdrawals, annuitizations, transfers, Certificate
Administration Charge and any applicable Withdrawal Charge. The Fixed Account
Accumulation Value shall not be less than the minimum values required by law in
the state where this Certificate is issued.

FIXED ACCOUNT GUARANTEE PERIOD OPTIONS AND INTEREST CREDITING



                                       9
<PAGE>   10

Any amounts allocated to the Fixed Account Options from the first Purchase
Payment will earn interest at the Initial Interest Rate for the Fixed Account
Option(s) selected for the duration of the Guarantee Period.

Subsequent Purchase Payments allocated to the Fixed Account Options will earn
interest at the Current Interest Rate for the Fixed Account Option(s) selected
for the duration of the Guarantee Period.

Transfers to the Fixed Account Options from the Subaccounts and amounts renewed
into the Fixed Account Options will earn interest at the Renewal Interest Rate
for the Fixed Account Option(s) selected for the duration of the Guarantee
Period.

For thirty (30) days following the date of expiration of a Guarantee Period, You
may renew for the same or any other Guarantee Period at the Renewal Interest
Rate or You may transfer all or a portion of the amount to the Subaccounts. If
You do not specify a Guarantee Period at the time of renewal, We will select the
same Guarantee Period as has just expired, crediting Your Certificate with the
Renewal Interest Rate in effect on the date of expiration of the Guarantee
Period, so long as such Guarantee Period does not extend beyond the Annuity
Date. If a renewal occurs within one year of the latest Annuity Date, We will
credit interest up to the Annuity Date at the Renewal Interest Rate for the
1-Year Fixed Account Option.

If you are participating in the DCA program, Purchase Payments may be allocated
to the 1-Year DCA Fixed Account Option or the 1-Year Fixed Account Option. Upon
termination of the DCA program, any amounts remaining in the 1-Year DCA Fixed
Account Option will be automatically transferred to the 1-Year Fixed Account
Option. Such amounts will earn interest at the Renewal Interest Rate for the
1-Year Fixed Account Option.

MARKET VALUE ADJUSTMENT (MVA)

Any payments and values based on the 3, 5, 7 or 10-year Fixed Account Options
may be subject to an MVA, the operation of which may result in upward or
downward adjustments in the Certificate Value, if withdrawn, transferred or
annuitized prior to the end of the respective Guarantee Period. The MVA will be
calculated by multiplying the amount withdrawn, transferred or annuitized by the
following formula:

                                     N/12
               {(1 + I)/(1+J+0.0050)}     -1

I = The interest rate currently in effect for that Guarantee Period.

J = The Initial Interest Rate available for the Guarantee Period equal to the
number of years (rounded up to an integer) remaining in the current Guarantee
Period at the time of withdrawal, transfer or annuitization. In the
determination of J, if the Company currently does not offer the applicable
Guarantee Period, then the rate will be determined by linear interpolation of
the Initial Interest Rate for the nearest two Guarantee Periods that are
available.

N = The number of full months remaining in the current Guarantee Period at the
time the withdrawal or annuitization request is processed.



                                       10
<PAGE>   11

If a Withdrawal Charge is applied to a withdrawal, then the MVA will be applied
to the withdrawal amount net of the Withdrawal Charge.

There will be no MVA on withdrawals from the Fixed Account Options in the
following situations: (1) to pay a Death Benefit paid upon death of the
Participant; (2) on amounts withdrawn to pay fees or charges; (3) on amounts
withdrawn from the Fixed Account Options within thirty (30) days after the end
of the Guarantee Period; (4) on annuitizations on the Latest Annuity Date; (5)
on amounts withdrawn from the 1-Year Fixed Account Option or the 1-Year DCA
Fixed Account Option.

                             CHARGES AND DEDUCTIONS

We will deduct the following charges from the Certificate:

CERTIFICATE ADMINISTRATION CHARGE

The charge specified on the Certificate Data Page will be deducted on each
Certificate anniversary that occurs on or prior to the Annuity Date. It will
also be deducted when the Certificate Value is withdrawn in full if withdrawal
is not on the Certificate anniversary. We reserve the right to assess a charge
on a class basis which is less than the charge specified on the Certificate Data
Page.

WITHDRAWAL CHARGE

This charge may be deducted upon withdrawal of any portion of the Certificate
Value. See WITHDRAWAL PROVISIONS.

MORTALITY RISK CHARGE

On an annual basis this charge equals 0.90% of the average daily total net asset
value of the Subaccounts to which Your Purchase Payments are allocated. This
charge is to compensate Us for assuming the mortality risks under the
Certificate.

EXPENSE RISK CHARGE

On an annual basis this charge equals 0.35% of the average daily total net asset
value of the Subaccounts to which Your Purchase Payments are allocated. This
charge is to compensate Us for assuming the expense risks under the Certificate.

DISTRIBUTION EXPENSE CHARGE

On an annual basis this charge equals 0.15% of the average daily total net asset
value of the Subaccounts to which Your Purchase Payments are allocated. This
charge is to compensate Us for all distribution expenses associated with the
Certificate.

GUARANTEED DEATH BENEFIT RISK CHARGE

On an annual basis this charge equals 0.12% of the average daily total net asset
value of the Subaccounts to which Your Purchase Payments are allocated. This
charge is to compensate Us for the risk assumed as a result of contractual
obligations to provide a minimum guaranteed Death Benefit prior to the Annuity
Date.



                                       11
<PAGE>   12

                               TRANSFER PROVISIONS

Prior to the Annuity Date, You may transfer all or part of Your Certificate
Value to any of the Subaccounts or Fixed Account Options subject to certain
restrictions. We reserve the right to charge a fee for transfers if the number
of transfers exceeds the limit specified by Us. The minimum amount that can be
transferred and the amount that can remain in a Subaccount or Fixed Account
Option are subject to Company limits.

TRANSFERS OF ACCUMULATION AND ANNUITY UNITS BETWEEN SUBACCOUNTS

Prior to the Annuity Date, You may transfer all or a portion of Your Certificate
Value between Subaccounts. A transfer will result in the purchase of
Accumulation Units in a Subaccount and the redemption of Accumulation Units in
the other Subaccount. Transfers will be effected at the next computed
Accumulation Unit Value following Our receipt of Your request for transfer.
Accumulation Unit Values are calculated at the close of each NYSE business day.

After the Annuity Date, You may transfer all or a portion of Your Certificate
Value from one Subaccount to another Subaccount. A transfer will result in the
purchase of Annuity Units in a Subaccount and the redemption of Annuity Units in
the other Subaccount. Transfers will be effected for the last NYSE business day
of the month in which We receive Your request for the transfer.

TRANSFERS OF ACCUMULATION UNITS TO AND FROM THE FIXED ACCOUNT

Prior to the Annuity Date, You may transfer all or any part of Your Certificate
Value from the Subaccount(s) to the Fixed Account Option(s) or from the Fixed
Account Option(s) to the Subaccount(s) of the Certificate. However, You may only
transfer to the 1-Year DCA Fixed Account Option if You are participating in the
DCA program.

After the Annuity Date, transfers into or out of the Fixed Account Option(s) are
not allowed.

                              WITHDRAWAL PROVISIONS

On or before the Annuity Date and while the Participant is living, You may
withdraw all or part of Your Certificate Value under this Certificate by
informing Us at Our Annuity Service Center. For a full withdrawal, this
Certificate must be returned to Our Annuity Service Center. The 



                                       12
<PAGE>   13
minimum amount that can be withdrawn and the amount remaining after withdrawal
are subject to Company limits.

Without a written notice to the contrary, withdrawals will be deducted from the
Certificate Value in proportion to their allocation among the Fixed Account
Options and the Subaccounts. Withdrawals will be based on values for the NYSE
business day in which the request for withdrawal and the Certificate (in the
case of a full withdrawal), are received at Our Executive Office. Unless the
SUSPENSION OF PAYMENTS or DEFERMENT OF PAYMENTS sections are in effect, payment
of withdrawals will be made within seven calendar days.

WITHDRAWAL CHARGE

Withdrawals of all or a portion of the Certificate Value may be subject to a
Withdrawal Charge as shown in the chart below. The Withdrawal Charge applied to
any withdrawal will depend on how long the Purchase Payment to which the
withdrawal is attributed has been in the Certificate. No Withdrawal Charge is
made on an amount withdrawn which is considered to be a withdrawal of
penalty-free earnings.

For the purpose of determining the Withdrawal Charge, a withdrawal will be
attributed to amounts in the following order: (1) penalty-free earnings in the
Certificate; (2) Purchase Payments which are both no longer subject to the
Withdrawal Charge and are not yet withdrawn; (3) any remaining Penalty-Free
Withdrawal amount (except in the case of a full surrender); and (4) Purchase
Payments subject to a Withdrawal Charge. Purchase Payments, when withdrawn, are
assumed to be withdrawn on a first-in-first-out (FIFO) basis. You will not
receive the benefit of a Penalty-Free Withdrawal in a full surrender.

</TABLE>


The Withdrawal Charge will be assessed against the Subaccounts and the Fixed
Account Options in the same proportion as the remaining Certificate Value is
allocated unless You request that the withdrawal come from a particular Fixed
Account Option or Subaccount. If the remaining Certificate Value is insufficient
to cover the Withdrawal Charge, any remaining balance will be deducted from the
withdrawal amount requested.

PENALTY-FREE WITHDRAWALS



                                       13
<PAGE>   14

As of any day, You may make a withdrawal of up to the Penalty-Free Withdrawal
amount for that day without incurring a Withdrawal Charge. Any Penalty-Free
Withdrawal made in excess of penalty-free earnings in the Certificate is
considered to be a withdrawal of future penalty-free earnings and is therefore
not a withdrawal of the Total Invested Amount. On any day, penalty-free earnings
in the Certificate are calculated as the Certificate Value at the end of that
day less the Total Invested Amount.

During the first Certificate Year, the Penalty-Free Withdrawal amount is equal
to the penalty-free earnings in the Certificate as of the date of withdrawal.

Alternatively, during the first Certificate Year, You may make withdrawals of
the Penalty-Free Withdrawal amount through the Systematic Withdrawal Program.
The Penalty-Free Withdrawal amount as of any systematic withdrawal date is 10%
of the Total Invested Amount less any withdrawals already made during the
Certificate Year.

After the first Certificate Year, the maximum Penalty-Free Withdrawal amount as
of the date of the withdrawal is the greater of:

(a)     penalty-free earnings in the Certificate as of that date; or

(b)     10% of the Total Invested Amount on deposit for at least one year, less
        any withdrawals already made during the year.

Although amounts withdrawn free of a Withdrawal Charge may reduce principal,
they do not reduce the Total Invested Amount for purposes of calculating the
Withdrawal Charge or for the purposes of calculating penalty-free earnings in
the Certificate. As a result, You will not receive the benefit of a Penalty-Free
Withdrawal in a full surrender.

SYSTEMATIC WITHDRAWAL PROGRAM

Prior to the Annuity Date, You may elect to participate in the Systematic
Withdrawal Program by informing Us at Our Annuity Service Center. The Systematic
Withdrawal Program allows You to make automatic withdrawals from your account
monthly, quarterly, semiannually or annually. The minimum systematic withdrawal
amount is $250 per withdrawal. Any amount withdrawn through the Systematic
Withdrawal Program may be subject to a Withdrawal Charge and a Market Value
Adjustment as discussed in the WITHDRAWAL CHARGE, PENALTY-FREE WITHDRAWALS and
MARKET VALUE ADJUSTMENT provisions. You may terminate Your participation in the
Systematic Withdrawal Program at any time by sending us a written request.

Systematic withdrawals will be deducted from the Penalty-Free Withdrawal amount
available each Certificate Year.

                                DEATH PROVISIONS

Notwithstanding any provision of this Certificate to the contrary, all payments
of benefits under this Certificate will be made in a manner that satisfies the
requirements of IRC Section 72(s), as amended from time to time. If the
Certificate is owned by a trust or other non-natural person, We will treat the
death of any Annuitant as the death of the "Primary Annuitant" and as the death
of any Participant.

DEATH OF PARTICIPANT BEFORE THE ANNUITY DATE. We will pay a death benefit to the
Beneficiary upon Our receiving all required documentation including: (a) due
proof that any Participant died before the Annuity Date; and (b) an election
form selecting the payment option form the options listed below. If no election
is received within 60 days of our receipt of 



                                       16
<PAGE>   17

due proof of death, the death benefit will be paid in accordance with option 1
below. The Beneficiary must select one of the following options:

               1.     Immediately collect the death benefit in a lump sum
                      payment. If a lump sum payment is elected, payment will be
                      in accordance with any applicable laws and regulations
                      governing payments and death; or

               2.     Collect the death benefit in the form of one of the
                      Annuity Payment Options. The payments must be over the
                      life of the Beneficiary or over a period not extending
                      beyond the life expectancy of the Beneficiary. Payments
                      under this option must commence within one year after the
                      Participant's death, otherwise, the death benefit will be
                      paid in accordance with option 1 above; or

               3.     If the Beneficiary is the Participant's spouse, the
                      Beneficiary may elect to become the Participant and
                      continue the Certificate in force. If this option is
                      elected, no death benefit is paid. Upon the new
                      Participant's subsequent death, the entire interest must
                      be distributed immediately under option 1 or 2 above.

In any event, the entire interest in the Certificate will be distributed within
five years from the date of death of the Participant.

DUE PROOF OF DEATH Due Proof of Death means:

               1.     a certified copy of a death certificate; or

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

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

               4.     any other proof satisfactory to Us.

AMOUNT OF DEATH BENEFIT

The amount of the death benefit will be determined based upon your selection on
the Participant Enrollment Form. Once selected, the death benefit option cannot
be changed. The death benefit options are as described below.

OPTION I:   PURCHASE PAYMENT ACCUMULATION DEATH BENEFIT OPTION

Prior to the Annuity Date and upon death of the Participant, the Beneficiary
will receive the greatest of:



                                       17
<PAGE>   18

     1. the Certificate Value for the NYSE business day during which We receive
        all required documentation including due proof of death of the
        Participant and an election of the type of payment to be made at Our
        Annuity Service Center; or

     2. Purchase Payments less any partial withdrawals, compounded until the
        date of death at 4% interest, plus any Purchase Payments and less any
        withdrawals recorded after the date of death; or

     3. the Certificate Value at the seventh Certificate anniversary, plus any
        subsequent Purchase Payments and less any subsequent partial withdrawals
        compounded until the date of death at 4% interest, plus any Purchase
        Payments and less any partial withdrawals recorded after the date of
        death.

If the Participant was age 70 or older on the Certificate Date, both (2) and (3)
above will be compounded at 3%, rather than 4%. If the death benefit is paid on
the death of a Participant who was not originally named in the application and
was age 70 or older on the Certificate Date, both (2) and (3) above will be
compounded at 3%, rather than 4%.

OPTION II:  MAXIMUM ANNIVERSARY VALUE DEATH BENEFIT OPTION

    If, upon the death of the Participant and prior to the Annuity Date, the
    Participant has not attained his or her 90th birthday, the Beneficiary will
    receive the greatest of:

     1. the Certificate Value for the NYSE business day during which We receive
        all required documentation including due proof of death the Participant
        and an election of the type of payment to be made at Our Annuity Service
        Center; or

     2. Purchase Payments less any partial withdrawals; or

     3. the maximum anniversary value preceding the date of death. The maximum
        anniversary value is equal to the greatest anniversary value attained
        from the following:

        As of the date of receipt of due proof of death and an election of the
        type of payment to be made, at our Annuity Service Center, We will
        calculate an anniversary value for each Certificate anniversary prior to
        the Participant's 81st birthday. The anniversary value is equal to the
        Certificate Value on a Certificate anniversary, increased by the dollar
        amount of any Purchase Payments made since that anniversary and reduced
        by the dollar amount of any partial withdrawals since that anniversary.

If the deceased Participant has attained age 90, then the death benefit will be
the Certificate Value as defined in (1) above.

DEATH OF PARTICIPANT OR ANNUITANT ON OR AFTER THE ANNUITY DATE. If any
Participant or Annuitant dies on or after the Annuity Date and before the entire
interest in the Certificate has been distributed, We will pay the remaining
portion of the interest of the 



                                       18
<PAGE>   19

Certificate under the annuity payment option being used on the date of death.
For further information pertaining to death of the Annuitant, see ANNUITY
PAYMENT OPTIONS.

BENEFICIARY

The Beneficiary is as designated on the Participant Enrollment Form unless later
changed by the Participant. While: (a) the Participant is living; and (b) before
the Annuity Date, the Participant may change the Beneficiary by written notice
in a form satisfactory to Us. The change will take effect on the date We record
the proper notice subject to any payments We have made. If two or more persons
are named: (a) those surviving the Participant will share equally unless
otherwise stated; and (b) the Beneficiaries must elect to receive their
respective portions of the death benefit according to the options listed under
DEATH OF PARTICIPANT BEFORE THE ANNUITY DATE. If the Annuitant survives the
Participant, and there are no surviving Beneficiaries, the Annuitant will be
deemed the Beneficiary.

Joint Participants, if applicable, shall be each other's primary Beneficiary.
Joint Annuitants, if any, when the Participant is a non-natural person, shall be
each other's primary Beneficiary. Any other Beneficiary designated on the
Participant Enrollment Form will be treated as a contingent Beneficiary.

If the Participant is also the Annuitant and there are no surviving
Beneficiaries at the death of the Participant, the death benefit will be paid to
the estate of the Participant in accordance with option 1, under DEATH OF
PARTICIPANT BEFORE THE ANNUITY DATE.

                               ANNUITY PROVISIONS

ANNUITY DATE

The Participant selects an Annuity Date (the date on which annuity payments are
to begin) at the time of application. The Participant may change the Annuity
Date at any time, at least seven days prior to the Annuity Date, by written
notice to the Company at its Annuity Service Center. The Annuity Date must
always be the first day of the calendar month and must be at least two years
after the Certificate Date, but not beyond the later of the Participant's 90th
birthday or ten years after the Certificate Date. If the Participant is a
non-natural person, the latest Annuity Date is the later of the Annuitant's 90th
birthday or ten years after the Certificate Date. If no Annuity Date is
selected, the Annuity Date will be the latest Annuity Date, as set by the
Company.

PAYMENTS TO PARTICIPANT

Unless You request otherwise, We will make annuity payments to You. If You want
the annuity payments to be made to some other Payee, We will make such payments
subject to receipt of a written request filed at the Annuity Service Center no
later than thirty (30) days before the due date of the first annuity payment.

Any such request is subject to the rights of any assignee. No payments available
to or being paid to the Payee while the Annuitant is alive can be transferred,
commuted, anticipated or encumbered.

FIXED ANNUITY PAYMENTS



                                       19
<PAGE>   20

If a Fixed Annuity payment option has been elected, the proceeds payable under
this Certificate less any applicable premium taxes, shall be applied to the
payment of the Fixed Annuity payment option elected at rates which are at least
equal to the annuity rates based upon the applicable tables in the Certificate.
In no event will the Fixed Annuity payments be changed once they begin.

AMOUNT OF FIXED ANNUITY PAYMENTS

The amount of each Fixed Annuity payment will be determined by applying the
portion of the Certificate Value allocated to Fixed Annuity payments less any
applicable premium taxes to the annuity table applicable to the Fixed Annuity
payment option chosen.

AMOUNT OF VARIABLE ANNUITY PAYMENTS

(a)     FIRST VARIABLE ANNUITY PAYMENT: The dollar amount of the first Variable
        Annuity payment will be determined by applying the portion of the
        Certificate Value allocated to the Subaccount, less any applicable
        premium taxes, to rates which are at least equal to the annuity rates
        based upon the annuity table applicable to the Variable Annuity payment
        option chosen. If the Certificate Value is allocated to more than one
        Subaccount, the value of Your interest in each Subaccount is applied
        separately to the Variable Annuity payment option table to determine the
        amount of the first annuity payment attributable to each Subaccount.

(b)     NUMBER OF VARIABLE ANNUITY UNITS: The number of Annuity Units for each
        applicable Subaccount is the amount of the first annuity payment
        attributable to that Subaccount divided by the value of the applicable
        Annuity Unit for that Subaccount as of the Annuity Date. The number will
        not change as a result of investment experience.

(c)     VALUE OF EACH VARIABLE ANNUITY UNIT: The value of an Annuity Unit may
        increase or decrease from one month to the next. For any month, the
        value of an Annuity Unit of a particular Subaccount is the value of that
        Annuity Unit as of the last NYSE business day of the preceding month,
        multiplied by the Net Investment Factor for that Subaccount for the last
        NYSE business day of the current month.

The Net Investment Factor for any Subaccount for a certain month is determined
by dividing (1) by (2) where:

               (1)    is the Accumulation Unit Value of the Subaccount
                      determined as of the last business day at the end of that
                      month, and

               (2)    is the Accumulation Unit Value of the Subaccount
                      determined as of the last business day at the end of the
                      preceding month.

The result is then multiplied by a factor that neutralizes the assumed
investment rate of 3.5%.

(d)     SUBSEQUENT VARIABLE ANNUITY PAYMENTS: After the first Variable Annuity
        payment, payments will vary in amount according to the investment
        performance of the applicable Subaccount(s) to which Your Purchase
        Payments are allocated. The amount may change from month to month. The
        amount of each subsequent payment for each Subaccount is:



                                       20
<PAGE>   21

The number of Annuity Units for each Subaccount as determined for the first
annuity payment

Multiplied by

The value of an Annuity Unit for that Subaccount at the end of the month
immediately preceding the month in which payment is due.

We guarantee that the amount of each Variable Annuity payment will not be
affected by variations in expenses or mortality experience.

                             ANNUITY PAYMENT OPTIONS

During the Annuitant's life, upon written election and the return of this
Certificate to the Company at its Annuity Service Center, the Certificate Value
may be applied to provide one of the following options or any annuity payment
option that is mutually agreeable. After two years from the Certificate Date,
and prior to the Annuity Date, You can choose one of the options described
below. If no option has been selected by the Annuity Date, You will
automatically receive option 4, below, with 120 monthly payments guaranteed.

OPTIONS 3 & 3V - JOINT AND SURVIVOR LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR 10
YEARS Payments are payable to the Payee during the lifetime of the Annuitant and

guaranteed annuity payments will be continued to the Beneficiary.

OPTIONS 4 & 4V - LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR 10 OR 20 YEARS

Payments payable to the Payee during the lifetime of the Annuitant. If, at the
death of the Annuitant, payments have been made for less than the 10 or 20

OPTIONS 5 & 5V - FIXED PAYMENTS FOR A SPECIFIED PERIOD CERTAIN

Payments payable to the Payee for any specified period of time for five (5)
years or more, but not exceeding thirty (30) years, as selected at the time of

event of death of the Annuitant, any remaining annuity payments will be
continued to the Beneficiary.

                                  ENDORSEMENT

This endorsement forms a part of the Certificate to which it is attached.

The following provisions are modified to read as follows:
        
        1. THE DOLLAR COST AVERAGING (DCA) OR AUTOMATIC DOLLAR COST AVERAGING
           PROGRAM (DCA) DEFINITION IN THE CERTIFICATE IS DELETED IN ITS
           ENTIRETY AND REPLACED WITH THE FOLLOWING:

           You may authorize the automatic transfer of amounts, at the interval
           selected by You, from the DCA Fixed Account Option(s) to any
           Subaccount(s). All amounts allocated to a DCA Fixed Account Option
           will be transferred out within the specified DCA Fixed Account
           period. You may also authorize the automatic transfer of amounts at
           regular intervals and specified amounts or percentages from the
           1-Year Fixed Account Option or any of the Subaccounts to any other
           Subaccount(s) (other than the source account). The unit values
           credited and applied to Your Certificate are determined on the dates
           of transfer(s). You may terminate the DCA program at any time.
           However, upon termination or annuitization, any amounts remaining in
           the DCA Fixed Account Options will be transferred to the 1-Year Fixed
           Account Option. We reserve the right to change the terms and
           conditions of the DCA program at any time.

        2. THE LAST PARAGRAPH UNDER THE PROVISION ENTITLED FIXED ACCOUNT
           GUARANTEE PERIOD OPTIONS AND INTEREST CREDITING IS DELETED IN ITS
           ENTIRETY AND REPLACED WITH THE FOLLOWING:

           If You are participating in the DCA program, Purchase Payments may be
           allocated to a DCA Fixed Account Option or the 1-Year Fixed Account
           Option. Upon termination of the DCA program, any amounts remaining in
           the DCA Fixed Account Options will be automatically transferred to
           the 1-Year Fixed Account Option. Such amounts will earn interest at
           the Renewal Interest Rate for the 1-Year Fixed Account Option.

        3. THE LAST PARAGRAPH UNDER THE PROVISION ENTITLED MARKET VALUE
           ADJUSTMENT (MVA) ITEM (5) IS DELETED IN ITS ENTIRETY AND REPLACED
           WITH THE FOLLOWING SENTENCE:

           (5) on amounts withdrawn from the DCA Fixed Account Options or the
           1-Year Fixed Account Option.

        4. UNDER THE PROVISION ENTITLED TRANSFER OF ACCUMULATION UNITS TO AND
           FROM THE FIXED ACCOUNT, THE FIRST PARAGRAPH IS MODIFIED TO READ:

           Prior to the Annuity Date, You may transfer all or any part of Your
           Certificate Value from the Subaccount(s) to any Fixed Account
           Options(s) other than the DCA Fixed Account Options or from the Fixed
           Account Option(s) to the Subaccount(s) of the Certificate.

All other terms and conditions of the Certificate remain unchanged. Signed for
the Company at Los Angeles, California, to be effective as of the Certificate
Date.

provisions set forth in this Contract and in consideration of the Application
and Purchase Payments We received.

THE VALUE OF AMOUNTS ALLOCATED TO THE SEPARATE ACCOUNT DURING THE ACCUMULATION

BENEFIT OF AMOUNTS ALLOCATED TO NON-MVA FIXED ACCOUNT OPTIONS.

RIGHT TO EXAMINE - YOU MAY RETURN THIS CONTRACT TO OUR ANNUITY SERVICE CENTER OR
TO THE AGENT THROUGH WHOM THE CONTRACT WAS PURCHASED WITHIN 10 DAYS AFTER YOU
RECEIVE IT, IF YOU ARE NOT SATISFIED WITH IT. THE COMPANY WILL REFUND THE
CONTRACT VALUE ON THE BUSINESS DAY DURING WHICH THE CONTRACT IS RECEIVED. UPON
SUCH REFUND, THE CONTRACT SHALL BE VOID.

For Individual Retirement Annuities, a refund of the Purchase Payment(s) may be
required. Therefore, We reserve the right to allocate your Purchase Payment(s)
to the Cash Management Subaccount until the end of the Right To Examine period.
Thereafter, allocations will be made as shown on the Contract Data Page.

                             ACCUMULATION PROVISIONS

SEPARATE ACCOUNT ACCUMULATION VALUE

The Separate Account Accumulation Value under the Contract shall be the sum of
the values of the Accumulation Units held in the Subaccounts for the Owner.

NUMBER OF ACCUMULATION UNITS

For each Subaccount, the number of Accumulation Units is the sum of each
Purchase Payment and transfer amount allocated to the Subaccount, reduced by
premium taxes, if any:

Divided by

The Accumulation Unit value for that Subaccount for the NYSE business day in
which the Purchase Payment or transfer amount is received.

The number of Accumulation Units will be similarly adjusted for withdrawals,
annuitizations, transfers and charges. Adjustments will be made as of the NYSE
business day in which We receive all requirements for the transaction, as
appropriate.

ACCUMULATION UNIT VALUE (AUV)

The AUV of a Subaccount for any NYSE business day is calculated by subtracting
(2) from (1) and dividing the result by (3) where:

(1)     is the total value for the given NYSE business day of the assets
        attributable to the Accumulation Units of the Subaccount minus the total
        liabilities;

(2)     is the cumulative unpaid charge for assumption of Expense Risk,
        Distribution Expense, Mortality Risk and Guaranteed Death Benefit Risk
        charges (See CHARGES AND DEDUCTIONS);

(3)     is the number of Accumulation Units outstanding at the end of the given
        NYSE business day.

FIXED ACCOUNT ACCUMULATION VALUE

Under the Contract, the Fixed Account Accumulation Value shall be the sum of all
monies allocated or transferred to the Fixed Account Option(s), reduced by any
applicable premium taxes, plus all interest credited on the Fixed Account
Option(s) during the period that the Contract has been in effect. This amount
shall be adjusted for withdrawals, annuitizations, transfers, Contract
Administration Charge and any applicable Withdrawal Charge. The Fixed Account
Accumulation Value shall not be less than the minimum values required by law in
the state where this Contract is issued.

FIXED ACCOUNT GUARANTEE PERIOD OPTIONS AND INTEREST CREDITING



                                       11
<PAGE>   12

Any amounts allocated to the Fixed Account Options from the first Purchase
Payment will earn interest at the Initial Interest Rate for the Fixed Account
Option(s) selected for the duration of the Guarantee Period.

Subsequent Purchase Payments allocated to the Fixed Account Options will earn
interest at the Current Interest Rate for the Fixed Account Option(s) selected
for the duration of the Guarantee Period.

Transfers to the Fixed Account Options from the Subaccounts and amounts renewed
into the Fixed Account Options will earn interest at the Renewal Interest Rate
for the Fixed Account Option(s) selected for the duration of the Guarantee
Period.

For thirty (30) days following the date of expiration of a Guarantee Period, You
may renew for the same or any other Guarantee Period at the Renewal Interest
Rate or You may transfer all or a portion of the amount to the Subaccounts. If
You do not specify a Guarantee Period at the time of renewal, We will select the
same Guarantee Period as has just expired, crediting Your Contract with the
Renewal Interest Rate in effect on the date of expiration of the Guarantee
Period, so long as such Guarantee Period does not extend beyond the Annuity
Date. If a renewal occurs within one year of the latest Annuity Date, We will
credit interest up to the Annuity Date at the Renewal Interest Rate for the
1-Year Fixed Account Option.

If you are participating in the DCA program, Purchase Payments may be allocated
to the 1-Year DCA Fixed Account Option or the 1-Year Fixed Account Option. Upon
termination of the DCA program, any amounts remaining in the 1-Year DCA Fixed
Account Option will be automatically transferred to the 1-Year Fixed Account
Option. Such amounts will earn interest at the Renewal Interest Rate for the
1-Year Fixed Account Option.

MARKET VALUE ADJUSTMENT (MVA)

Any payments and values based on the 3, 5, 7 or 10-year Fixed Account Options
may be subject to an MVA, the operation of which may result in upward or
downward adjustments in the Contract Value, if withdrawn, transferred or
annuitized prior to the end of the respective Guarantee Period. The MVA will be
calculated by multiplying the amount withdrawn, transferred or annuitized by the
following formula:

                                     N/12
               {(1 + I)/(1+J+0.0050)}     -1

I = The interest rate currently in effect for that Guarantee Period.

J = The Initial Interest Rate available for the Guarantee Period equal to the
number of years (rounded up to an integer) remaining in the current Guarantee
Period at the time of withdrawal, transfer or annuitization. In the
determination of J, if the Company currently does not offer the applicable
Guarantee Period, then the rate will be determined by linear interpolation of
the Initial Interest Rate for the nearest two Guarantee Periods that are
available.

N = The number of full months remaining in the current Guarantee Period at the
time the withdrawal or annuitization request is processed.



                                       12
<PAGE>   13

If a Withdrawal Charge is applied to a withdrawal, then the MVA will be applied
to the withdrawal amount net of the Withdrawal Charge.

There will be no MVA on withdrawals from the Fixed Account Options in the
following situations: (1) to pay a Death Benefit paid upon death of the Owner;
(2) on amounts withdrawn to pay fees or charges; (3) on amounts withdrawn from
the Fixed Account Options within thirty (30) days after the end of the Guarantee
Period; (4) on annuitizations on the Latest Annuity Date; (5) on amounts
withdrawn from the 1-Year Fixed Account Option or the 1-Year DCA Fixed Account
Option .

                             CHARGES AND DEDUCTIONS

We will deduct the following charges from the Contract:

CONTRACT ADMINISTRATION CHARGE

The charge specified on the Contract Data Page will be deducted on each Contract
anniversary that occurs on or prior to the Annuity Date. It will also be
deducted when the Contract Value is withdrawn in full if withdrawal is not on
the Contract anniversary. We reserve the right to assess a charge on a class
basis which is less than the charge specified on the Contract Data Page.

WITHDRAWAL CHARGE

This charge may be deducted upon withdrawal of any portion of the Contract
Value. See WITHDRAWAL PROVISIONS.

MORTALITY RISK CHARGE

On an annual basis this charge equals 0.90% of the average daily total net asset
value of the Subaccounts to which Your Purchase Payments are allocated. This
charge is to compensate Us for assuming the mortality risks under the Contract.

EXPENSE RISK CHARGE

On an annual basis this charge equals 0.35% of the average daily total net asset
value of the Subaccounts to which Your Purchase Payments are allocated. This
charge is to compensate Us for assuming the expense risks under the Contract.

DISTRIBUTION EXPENSE CHARGE

On an annual basis this charge equals 0.15% of the average daily total net asset
value of the Subaccounts to which Your Purchase Payments are allocated. This
charge is to compensate Us for all distribution expenses associated with the
Contract.

GUARANTEED DEATH BENEFIT RISK CHARGE

On an annual basis this charge equals 0.12% of the average daily total net asset
value of the Subaccounts to which Your Purchase Payments are allocated. This
charge is to compensate Us for the risk assumed as a result of contractual
obligations to provide a minimum guaranteed Death Benefit prior to the Annuity
Date.



                                       13
<PAGE>   14

                               TRANSFER PROVISIONS

Prior to the Annuity Date, You may transfer all or part of Your Contract Value
to any of the Subaccounts or Fixed Account Options subject to certain
restrictions. We reserve the right to charge a fee for transfers if the number
of transfers exceeds the limit specified by Us. The minimum amount that can be
transferred and the amount that can remain in a Subaccount or Fixed Account
Option are subject to Company limits.

TRANSFERS OF ACCUMULATION AND ANNUITY UNITS BETWEEN SUBACCOUNTS

Prior to the Annuity Date, You may transfer all or a portion of Your Contract
Value between Subaccounts. A transfer will result in the purchase of
Accumulation Units in a Subaccount and the redemption of Accumulation Units in
the other Subaccount. Transfers will be effected at the next computed
Accumulation Unit Value following Our receipt of Your request for transfer.
Accumulation Unit Values are calculated at the close of each NYSE business day.

After the Annuity Date, You may transfer all or a portion of Your Contract Value
from one Subaccount to another Subaccount. A transfer will result in the
purchase of Annuity Units in a Subaccount and the redemption of Annuity Units in
the other Subaccount. Transfers will be effected for the last NYSE business day
of the month in which We receive Your request for the transfer.

TRANSFERS OF ACCUMULATION UNITS TO AND FROM THE FIXED ACCOUNT

Prior to the Annuity Date, You may transfer all or any part of Your Contract
Value from the Subaccount(s) to the Fixed Account Option(s) or from the Fixed
Account Option(s) to the Subaccount(s) of the Contract. However, You may only
transfer to the 1-Year DCA Fixed Account Option if You are participating in the
DCA program.

After the Annuity Date, transfers into or out of the Fixed Account Option(s) are
not allowed.

                              WITHDRAWAL PROVISIONS

On or before the Annuity Date and while the Owner is living, You may withdraw
all or part of Your Contract Value under this Contract by informing Us at Our
Annuity Service Center. For a full withdrawal, this Contract must be returned to
Our Annuity Service Center. The minimum 



                                       14
<PAGE>   15

amount that can be withdrawn and the amount remaining after withdrawal are
subject to Company limits.

Without a written notice to the contrary, withdrawals will be deducted from the
Contract Value in proportion to their allocation among the Fixed Account Options
and the Subaccounts. Withdrawals will be based on values for the NYSE business
day in which the request for withdrawal and the Contract (in the case of a full
withdrawal), are received at Our Executive Office. Unless the SUSPENSION OF
PAYMENTS or DEFERMENT OF PAYMENTS sections are in effect, payment of withdrawals
will be made within seven calendar days.

WITHDRAWAL CHARGE

Withdrawals of all or a portion of the Contract Value may be subject to a
Withdrawal Charge as shown in the chart below. The Withdrawal Charge applied to
any withdrawal will depend on how long the Purchase Payment to which the
withdrawal is attributed has been in the Contract. No Withdrawal Charge is made
on an amount withdrawn which is considered to be a withdrawal of penalty-free
earnings.

For the purpose of determining the Withdrawal Charge, a withdrawal will be
attributed to amounts in the following order: (1) penalty-free earnings in the
Contract; (2) Purchase Payments which are both no longer subject to the
Withdrawal Charge and are not yet withdrawn; (3) any remaining Penalty-Free
Withdrawal amount (except in the case of a full surrender); and (4) Purchase
Payments subject to a Withdrawal Charge. Purchase Payments, when withdrawn, are
assumed to be withdrawn on a first-in-first-out (FIFO) basis. You will not
receive the benefit of a Penalty-Free Withdrawal in a full surrender.

</TABLE>

The Withdrawal Charge will be assessed against the Subaccounts and the Fixed
Account Options in the same proportion as the remaining Contract Value is
allocated unless You request that the withdrawal come from a particular Fixed
Account Option or Subaccount. If the remaining Contract Value is insufficient to
cover the Withdrawal Charge, any remaining balance will be deducted from the
withdrawal amount requested.

PENALTY-FREE WITHDRAWALS



                                       15
<PAGE>   16

As of any day, You may make a withdrawal of up to the Penalty-Free Withdrawal
amount for that day without incurring a Withdrawal Charge. Any Penalty-Free
Withdrawal made in excess of penalty-free earnings in the Contract is considered
to be a withdrawal of future penalty-free earnings and is therefore not a
withdrawal of the Total Invested Amount. On any day, penalty-free earnings in
the Contract are calculated as the Contract Value at the end of that day less
the Total Invested Amount.

During the first Contract Year, the Penalty-Free Withdrawal amount is equal to
the penalty-free earnings in the Contract as of the date of withdrawal.

Alternatively, during the first Contract Year, You may make withdrawals of the
Penalty-Free Withdrawal amount through the Systematic Withdrawal Program. The
Penalty-Free Withdrawal amount as of any systematic withdrawal date is 10% of
the Total Invested Amount less any withdrawals already made during the Contract
Year.

After the first Contract Year, the maximum Penalty-Free Withdrawal amount as of
the date of the withdrawal is the greater of:

(a)     penalty-free earnings in the Contract as of that date; or

(b)     10% of the Total Invested Amount on deposit for at least one year, less
        any withdrawals already made during the year.

Although amounts withdrawn free of a Withdrawal Charge may reduce principal,
they do not reduce the Total Invested Amount for purposes of calculating the
Withdrawal Charge or for the purposes of calculating penalty-free earnings in
the Contract. As a result, You will not receive the benefit of a Penalty-Free
Withdrawal in a full surrender.

SYSTEMATIC WITHDRAWAL PROGRAM

Prior to the Annuity Date, You may elect to participate in the Systematic
Withdrawal Program by informing Us at Our Annuity Service Center. The Systematic
Withdrawal Program allows You to make automatic withdrawals from your account
monthly, quarterly, semiannually or annually. The minimum systematic withdrawal
amount is $250 per withdrawal. Any amount withdrawn through the Systematic
Withdrawal Program may be subject to a Withdrawal Charge and a Market Value
Adjustment as discussed in the WITHDRAWAL CHARGE, PENALTY-FREE WITHDRAWALS and
MARKET VALUE ADJUSTMENT provisions. You may terminate Your participation in the
Systematic Withdrawal Program at any time by sending us a written request.

Systematic withdrawals will be deducted from the Penalty-Free Withdrawal amount
available each Contract Year.

                               GENERAL PROVISIONS

If the Owner is an individual, the Owner may change the Annuitant(s) at any time
prior to the Annuity Date. To make a change, the Owner must send a written

non-natural person, the Owner may not change the Annuitant.

DEATH OF ANNUITANT

If the Owner and Annuitant are different, and the Annuitant dies before the
Annuity Date, the Owner becomes the Annuitant until the Owner elects a new
Annuitant. If there are Joint Annuitants, upon the death of any Annuitant prior
to the Annuity Date, the Owner may elect a new Joint Annuitant. However, if the
Owner is a non-natural, We will treat the death of any Annuitant as the death of
the "Primary Annuitant" and as the death of the Owner, see DEATH PROVISIONS.

MISSTATEMENT OF AGE OR SEX

If the Age or sex of any Annuitant has been misstated, future annuity payments
will be adjusted using the correct Age and sex, according to Our rates in effect
on the date that annuity payments were determined. Any overpayment from the
1-Year Fixed Account Option, plus interest at the rate of 4% per year, will be
deducted from the next payment(s) due. Any underpayment from the 1-Year Fixed
Account Option, plus interest at the rate of 4% per year, will be paid in full
with the next payment due. Any overpayment from the Subaccounts will be deducted
from the next payment(s) due. Any underpayment from the Subaccounts will be paid
in full with the next payment due.

PROOF OF AGE, SEX, OR SURVIVAL

The Company may require satisfactory proof of correct Age or sex at any time. If
any payment under this Contract depends on the Annuitant being alive, the
Company may require satisfactory proof of survival.

CONFORMITY WITH STATE LAWS

The provisions of this Contract will be interpreted by the laws of the state in
which the enrollment form was signed or such other state as is required by law.
Any provision which, on the Contract Date, is in conflict with the law of such

                                       17
<PAGE>   18

taxable. We do not assume any responsibility for the validity or tax
consequences of any assignment.

CLAIMS OF CREDITORS

will be subject to claims of creditors or legal process.

PREMIUM TAXES OR OTHER TAXES

The Company may deduct from Your Contract Value any premium tax or other taxes
payable to a state or other government entity, if applicable. Should We advance
any amount so due, We are not waiving any right to collect such amount at a
later date. The Company will deduct any withholding taxes required by applicable
law.

                                DEATH PROVISIONS

Notwithstanding any provision of this Contract to the contrary, all payments of
benefits under this Contract will be made in a manner that satisfies the
requirements of IRC Section 72(s), as amended from time to time. If the Contract
is owned by a trust or other non-natural person, We will treat the death of any
Annuitant as the death of the "Primary Annuitant" and as the death of any Owner.

DEATH OF OWNER BEFORE THE ANNUITY DATE. We will pay a death benefit to the
Beneficiary upon Our receiving all required documentation including: (a) due
proof that any Owner died before the Annuity Date; and (b) an election form
selecting the payment option form the options listed below. If no election is
received within 60 days of our receipt of due proof of 



                                       18

death, the death benefit will be paid in accordance with option 1 below. The
Beneficiary must select one of the following options:

               1.     Immediately collect the death benefit in a lump sum
                      payment. If a lump sum payment is elected, payment will be
                      in accordance with any applicable laws and regulations
                      governing payments and death; or

               2.     Collect the death benefit in the form of one of the
                      Annuity Payment Options. The payments must be over the
                      life of the Beneficiary or over a period not extending
                      beyond the life expectancy of the Beneficiary. Payments
                      under this option must commence within one year after the
                      Owner's death, otherwise, the death benefit will be paid
                      in accordance with option 1 above; or

               3.     If the Beneficiary is the Owner's spouse, the Beneficiary
                      may elect to become the Owner and continue the Contract in
                      force. If this option is elected, no death benefit is
                      paid. Upon the new Owner's subsequent death, the entire
                      interest must be distributed immediately under option 1 or
                      2 above.

In any event, the entire interest in the Contract will be distributed within
five years from the date of death of the Owner.

DUE PROOF OF DEATH Due Proof of Death means:

               1.     a certified copy of a death certificate; or

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

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

               4.     any other proof satisfactory to Us.

AMOUNT OF DEATH BENEFIT

The amount of the death benefit will be determined based upon your selection on
the Application. Once selected, the death benefit option cannot be changed. The
death benefit options are as described below.

OPTION I:   PURCHASE PAYMENT ACCUMULATION DEATH BENEFIT OPTION

        Prior to the Annuity Date and upon death of the Owner, the Beneficiary
        will receive the greatest of:



                                       19
<PAGE>   20

     1. the Contract Value for the NYSE business day during which We receive all
        required documentation including due proof of death of the Owner and an
        election of the type of payment to be made at Our Annuity Service
        Center; or

     2. Purchase Payments less any partial withdrawals, compounded until the
        date of death at 4% interest, plus any Purchase Payments and less any
        withdrawals recorded after the date of death; or

     3. the Contract Value at the seventh Contract anniversary, plus any
        subsequent Purchase Payments and less any subsequent partial withdrawals
        compounded until the date of death at 4% interest, plus any Purchase
        Payments and less any partial withdrawals recorded after the date of
        death.

If the Owner was age 70 or older on the Contract Date, both (2) and (3) above
will be compounded at 3%, rather than 4%. If the death benefit is paid on the
death of an Owner who was not originally named in the application and was age 70
or older on the Contract Date, both (2) and (3) above will be compounded at 3%,
rather than 4%.

OPTION II:  MAXIMUM ANNIVERSARY VALUE DEATH BENEFIT OPTION

        If, upon the death of the Owner and prior to the Annuity Date, the Owner
        has not attained his or her 90th birthday, the Beneficiary will receive
        the greatest of:

     1. the Contract Value for the NYSE business day during which We receive all
        required documentation including due proof of death the Owner and an
        election of the type of payment to be made at Our Annuity Service
        Center; or

     2. Purchase Payments less any partial withdrawals; or

     3. the maximum anniversary value preceding the date of death. The maximum
        anniversary value is equal to the greatest anniversary value attained
        from the following:

        As of the date of receipt of due proof of death and an election of the
        type of payment to be made, at our Annuity Service Center, We will
        calculate an anniversary value for each Contract anniversary prior to
        the Owner's 81st birthday. The anniversary value is equal to the
        Contract Value on a Contract anniversary, increased by the dollar amount
        of any Purchase Payments made since that anniversary and reduced by the
        dollar amount of any partial withdrawals since that anniversary.

If the deceased Owner has attained age 90, then the death benefit will be the
Contract Value as defined in (1) above.

DEATH OF OWNER OR ANNUITANT ON OR AFTER THE ANNUITY DATE. If any Owner or
Annuitant dies on or after the Annuity Date and before the entire interest in
the Contract has been distributed, We will pay the remaining portion of the
interest of the Contract

                                       20
<PAGE>   21

under the annuity payment option being used on the date of death. For further
information pertaining to death of the Annuitant, see ANNUITY PAYMENT OPTIONS.

BENEFICIARY

The Beneficiary is as designated on the Application unless later changed by the
Owner. While: (a) the Owner is living; and (b) before the Annuity Date, the
Owner may change the Beneficiary by written notice in a form satisfactory to Us.
The change will take effect on the date We record the proper notice subject to
any payments We have made. If two or more persons are named: (a) those surviving
the Owner will share equally unless otherwise stated; and (b) the Beneficiaries
must elect to receive their respective portions of the death benefit according
to the options listed under DEATH OF OWNER BEFORE THE ANNUITY DATE. If the
Annuitant survives the Owner, and there are no surviving Beneficiaries, the
Annuitant will be deemed the Beneficiary.

Joint Owners, if applicable, shall be each other's primary Beneficiary. Joint
Annuitants, if any, when the Owner is a non-natural person, shall be each
other's primary Beneficiary. Any other Beneficiary designated on the Application
will be treated as a contingent Beneficiary.

If the Owner is also the Annuitant and there are no surviving Beneficiaries at
the death of the Owner, the death benefit will be paid to the estate of the
Owner in accordance with option 1, under DEATH OF OWNER BEFORE THE ANNUITY DATE.

                               ANNUITY PROVISIONS

ANNUITY DATE

The Owner selects an Annuity Date (the date on which annuity payments are to
begin) at the time of application. The Owner may change the Annuity Date at any
time, at least seven days prior to the Annuity Date, by written notice to the
Company at its Annuity Service Center. The Annuity Date must always be the first
day of the calendar month and must be at least two years after the Contract
Date, but not beyond the later of the Owner's 90th birthday or ten years after
the Contract Date. If the Owner is a non-natural person, the latest Annuity Date
is the later of the Annuitant's 90th birthday or ten years after the Contract
Date. If no Annuity Date is selected, the Annuity Date will be the latest
Annuity Date, as set by the Company.

PAYMENTS TO OWNER

Unless You request otherwise, We will make annuity payments to You. If You want
the annuity payments to be made to some other Payee, We will make such payments
subject to receipt of a written request filed at the Annuity Service Center no
later than thirty (30) days before the due date of the first annuity payment.

Any such request is subject to the rights of any assignee. No payments available
to or being paid to the Payee while the Annuitant is alive can be transferred,
commuted, anticipated or encumbered.

FIXED ANNUITY PAYMENTS

If a Fixed Annuity payment option has been elected, the proceeds payable under
this Contract less any applicable premium taxes, shall be applied to the payment
of the Fixed Annuity payment option elected at rates which are at least equal to
the annuity rates based upon the applicable tables in the Contract. In no event
will the Fixed Annuity payments be changed once they begin.



                                       21
<PAGE>   22

AMOUNT OF FIXED ANNUITY PAYMENTS

The amount of each Fixed Annuity payment will be determined by applying the
portion of the Contract Value allocated to Fixed Annuity payments less any
applicable premium taxes to the annuity table applicable to the Fixed Annuity
payment option chosen.

AMOUNT OF VARIABLE ANNUITY PAYMENTS

(a)     FIRST VARIABLE ANNUITY PAYMENT: The dollar amount of the first Variable
        Annuity payment will be determined by applying the portion of the
        Contract Value allocated to the Subaccount, less any applicable premium
        taxes, to rates which are at least equal to the annuity rates based upon
        the annuity table applicable to the Variable Annuity payment option
        chosen. If the Contract Value is allocated to more than one Subaccount,
        the value of Your interest in each Subaccount is applied separately to
        the Variable Annuity payment option table to determine the amount of the
        first annuity payment attributable to each Subaccount.

(b)     NUMBER OF VARIABLE ANNUITY UNITS: The number of Annuity Units for each
        applicable Subaccount is the amount of the first annuity payment
        attributable to that Subaccount divided by the value of the applicable
        Annuity Unit for that Subaccount as of the Annuity Date. The number will
        not change as a result of investment experience.

(c)     VALUE OF EACH VARIABLE ANNUITY UNIT: The value of an Annuity Unit may
        increase or decrease from one month to the next. For any month, the
        value of an Annuity Unit of a particular Subaccount is the value of that
        Annuity Unit as of the last NYSE business day of the preceding month,
        multiplied by the Net Investment Factor for that Subaccount for the last
        NYSE business day of the current month.

The Net Investment Factor for any Subaccount for a certain month is determined
by dividing (1) by (2) where:

               (1)    is the Accumulation Unit Value of the Subaccount
                      determined as of the last business day at the end of that
                      month, and

               (2)    is the Accumulation Unit Value of the Subaccount
                      determined as of the last business day at the end of the
                      preceding month.

The result is then multiplied by a factor that neutralizes the assumed
investment rate of 3.5%.

(d)     SUBSEQUENT VARIABLE ANNUITY PAYMENTS: After the first Variable Annuity
        payment, payments will vary in amount according to the investment
        performance of the applicable Subaccount(s) to which Your Purchase
        Payments are allocated. The amount may change from month to month. The
        amount of each subsequent payment for each Subaccount is :

The number of Annuity Units for each Subaccount as determined for the first
annuity payment

Multiplied by

The value of an Annuity Unit for that Subaccount at the end of the month
immediately preceding the month in which payment is due.



                                       22
<PAGE>   23

We guarantee that the amount of each Variable Annuity payment will not be
affected by variations in expenses or mortality experience.

Contract to the Company at its Annuity Service Center, the Contract Value may be
applied to provide one of the following options or any annuity payment option
that is mutually agreeable. After two years from the Contract Date, and prior to

guaranteed annuity payments will be continued to the Beneficiary.

OPTIONS 4 & 4v - LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR 10 OR 20 YEARS

Payments payable to the Payee during the lifetime of the Annuitant. If, at the

                     ANCHOR NATIONAL LIFE INSURANCE COMPANY

                                  ENDORSEMENT

This endorsement forms a part of the Certificate to which it is attached.

The following provisions are modified to read as follows:
        
        1. THE DOLLAR COST AVERAGING (DCA) OR AUTOMATIC DOLLAR COST AVERAGING
           PROGRAM (DCA) DEFINITION IN THE CERTIFICATE IS DELETED IN ITS
           ENTIRETY AND REPLACED WITH THE FOLLOWING:

           You may authorize the automatic transfer of amounts, at the interval
           selected by You, from the DCA Fixed Account Option(s) to any
           Subaccount(s). All amounts allocated to a DCA Fixed Account Option
           will be transferred out within the specified DCA Fixed Account
           period. You may also authorize the automatic transfer of amounts at
           regular intervals and specified amounts or percentages from the
           1-Year Fixed Account Option or any of the Subaccounts to any other
           Subaccount(s) (other than the source account). The unit values
           credited and applied to Your Certificate are determined on the dates
           of transfer(s). You may terminate the DCA program at any time.
           However, upon termination or annuitization, any amounts remaining in
           the DCA Fixed Account Options will be transferred to the 1-Year Fixed
           Account Option. We reserve the right to change the terms and
           conditions of the DCA program at any time.

        2. THE LAST PARAGRAPH UNDER THE PROVISION ENTITLED FIXED ACCOUNT
           GUARANTEE PERIOD OPTIONS AND INTEREST CREDITING IS DELETED IN ITS
           ENTIRETY AND REPLACED WITH THE FOLLOWING:

           If You are participating in the DCA program, Purchase Payments may be
           allocated to a DCA Fixed Account Option or the 1-Year Fixed Account
           Option. Upon termination of the DCA program, any amounts remaining in
           the DCA Fixed Account Options will be automatically transferred to
           the 1-Year Fixed Account Option. Such amounts will earn interest at
           the Renewal Interest Rate for the 1-Year Fixed Account Option.

        3. THE LAST PARAGRAPH UNDER THE PROVISION ENTITLED MARKET VALUE
           ADJUSTMENT (MVA) ITEM (5) IS DELETED IN ITS ENTIRETY AND REPLACED
           WITH THE FOLLOWING SENTENCE:

           (5) on amounts withdrawn from the DCA Fixed Account Options or the
           1-Year Fixed Account Option.

        4. UNDER THE PROVISION ENTITLED TRANSFER OF ACCUMULATION UNITS TO AND
           FROM THE FIXED ACCOUNT, THE FIRST PARAGRAPH IS MODIFIED TO READ:

           Prior to the Annuity Date, You may transfer all or any part of Your
           Certificate Value from the Subaccount(s) to any Fixed Account
           Options(s) other than the DCA Fixed Account Options or from the Fixed
           Account Option(s) to the Subaccount(s) of the Certificate.

All other terms and conditions of the Certificate remain unchanged. Signed for
the Company at Los Angeles, California, to be effective as of the Certificate
Date.

I.  TELEPHONE TRANSFERS AUTHORIZATION
    Do you wish to authorize telephone TRANSFERS, subject to the conditions set forth below?   

    [ ] YES [ ] NO
                                                                                               
    (If no election is indicated the Company will default to yes for transfers.)               
    If indicated above, I authorize the Company to accept telephone instructions for transfers 
    in any amount among subaccounts from anyone providing proper identification subject to     
    restrictions and limitations contained in the contract and related prospectus, if any. I   
    understand that I bear the risk of loss in the event of a telephone instruction not        
    authorized by me. The Company will not be responsible for any losses resulting from        
    unauthorized transactions if it follows reasonable procedures designed to verify the       
    identity of the caller and therefore, the Company will record telephone conversations      
    containing transaction instructions, request personal identification information before    
    acting upon telephone instructions and send written confirmation statements of transactions
    to the address of record.
