                             [POLARIS PROFILE LOGO]

   
THIS PROFILE IS A SUMMARY OF SOME OF THE MORE IMPORTANT POINTS THAT YOU SHOULD
KNOW AND CONSIDER BEFORE PURCHASING THE POLARIS 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.
 
                                February 2, 1998
    
 
================================================================================
   
                        1. THE POLARIS VARIABLE ANNUITY
    
================================================================================
 
The Polaris 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 offers a diverse selection of money managers and investment options. You
may divide your money among any or all of our 25 variable investment portfolios
and 5 fixed investment options. Your investment is not guaranteed. The value of
your Polaris 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 5 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 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.

================================================================================
   
                                  5. EXPENSES
    
================================================================================
 
Each year, we deduct a $35 contract maintenance fee 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 will apply to each subsequent transfer
($10 in Pennsylvania and Texas).
    
 
   
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.

                                    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
    
================================================================================
 
Earnings may be withdrawn at any time free of a withdrawal charge. After the
first year, the first withdrawal of the year will be free of a withdrawal charge
if it does not exceed the greater of: (1) earnings in your contract as of the
date you make the withdrawal or (2) 10% of the money you have invested for at
least one year and not yet withdrawn, less any withdrawals made during the year.
 
Although amounts withdrawn using the 10% provision may reduce principal for
purposes of calculating amounts available for future withdrawals of earnings,
they do not reduce the amount of money you invested for purposes of calculating
the withdrawal charge if you withdraw your entire contract value.
 
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. Withdrawals charges are not reflected in the chart.
Past performance is not a guarantee of future results.

                                9. DEATH BENEFIT
    
================================================================================
 
If you should die during the Accumulation Phase, your beneficiary will receive a
death benefit. The death benefit is the greater of:
 
  (1) the value of your contract, or
 
  (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).
================================================================================
   
                             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: 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 options 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 or the 1-year fixed investment 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: Aggressive Growth
    (.90%); Federated Value (1.03%); SunAmerica Balanced (1.00%); 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.  The Examples assume that no transfer fees were imposed. Although premium
    taxes may apply in certain states, they are not reflected.
    
 
4.  THESE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

=============================================================
                        1. THE POLARIS 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 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 25
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 5 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. 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 basis unless you
request in writing that payments be made on a 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.
 
                                        6
<PAGE>   13
 
     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
if 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 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
during the Income Phase. You may transfer money among the variable Portfolios or
among the fixed investment options.
    
 
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
                                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 80 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
 
                                        7
<PAGE>   14
 
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 your state) 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 (unless otherwise required by your state). 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.

YOU SHOULD READ THE PROSPECTUSES FOR THE ANCHOR SERIES TRUST AND THE SUNAMERICA
SERIES TRUST CAREFULLY BEFORE INVESTING. THESE PROSPECTUSES CONTAIN DETAILED
INFORMATION ABOUT THE PORTFOLIOS AND ARE ATTACHED TO THIS PROSPECTUS.
 
FIXED INVESTMENT OPTIONS
 
The contract also offers 5 fixed investment options. We currently offer fixed
investment options for 1, 3, 5, 7 and 10 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 will
not be less than 3%. 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 1-year fixed investment option is not registered under the Securities Act of
1933 and is 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.
 
If you take your money out of the fixed investment options (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.
    
 
                                        9
<PAGE>   16
 
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, quarterly, semiannual
or annual 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.
 
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 to invest
through periods of fluctuating prices.
 
Transfers under the program are included as part of 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 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%.
 
                                       10
<PAGE>   17
 
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 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>
- -------------------------------------------------------------
<S>             <C>    <C>    <C>    <C>    <C>    <C>    <C>    <C>
 YEAR             1      2      3      4      5      6      7     8+

 CHARGE
- -------------------------------------------------------------
</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
 
                                       11
<PAGE>   18
 
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 and Utah) 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 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 C 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
 
We will reduce or eliminate the amount of certain insurance charges 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.
 
=============================================================
                                    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. 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, 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.
 
                                       12
<PAGE>   19
 
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
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; and,
except in the case of an IRA as to the following (5) after you separate from
service after attaining age 55; (6) to the extent such withdrawals do not exceed
limitations set by the IRC for amounts paid during the taxable year for medical
care; and (7) 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, a contract
maintenance fee. (See "Expenses" for more complete information).
 
Your contract provides for a free withdrawal amount. Purchase Payments that are
no longer subject to a withdrawal charge and not previously withdrawn, plus
earnings, may be withdrawn free of a withdrawal charge at any time.
 
After the first year, the first withdrawal of the year will be free of a
withdrawal charge if it does not exceed the greater of: (1) earnings in your
contract as of the date you make the withdrawal or (2) 10% of the Purchase
Payments you invested for at least one year and not yet withdrawn, less any
withdrawals made during the year.
 
   
The portion of a free withdrawal which exceeds the sum of: (1) earnings in the
contract and (2) Purchase Payments which were both no longer subject to the
withdrawal charge schedule and not yet withdrawn is assumed to be a withdrawal
against future earnings. Although amounts withdrawn free of a withdrawal charge
under the 10% provision may reduce principal for purposes of calculating amounts
available for future withdrawals of earnings, they do not reduce the amount you
invested for purposes of calculating the withdrawal charge if you
    
 
                                       13
<PAGE>   20
 
withdraw your entire contract value. 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.
 
   
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 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
    
 
                                       14
<PAGE>   21
 
   
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 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.
 
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).
 
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 is 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.

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.
Anchor National disclaims any obligation to update forward-looking information.
    
 
   
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
    
 
                                       18
<PAGE>   25
 
   
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)
    
 
                                       19
<PAGE>   26
 
   
("Variable Annuity Product 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
    
 
                                       20
<PAGE>   27
 
   
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
    
 
                                       22

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
    
 
                                       23

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
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.
    
 
PROPERTIES
 
   
Anchor National's executive offices and its principal office are in leased
premises at 1 SunAmerica Center, Los Angeles, California. Anchor National,
through an affiliate, also leases office space in Torrance and Woodland Hills,
California. Anchor National's broker-dealer and asset management subsidiaries
lease offices in New York, New York.
    
 
   
Anchor National believes that such properties, including the equipment located
therein, are suitable and adequate to meet the requirements of its businesses.

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

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.

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

2.  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

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

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.

6.  CONTINGENT LIABILITIES
    
 
   
The Company has entered into three agreements in which it has provided liquidity
support for certain short-term securities of three municipalities by agreeing to
purchase such securities in the event there is no other buyer in the short-term
marketplace. In return the Company receives a fee. The maximum liability under
these guarantees is $242,600,000. Management does not anticipate any material
future losses with respect to these liquidity support facilities.
    
 
   
The Company is involved in various kinds of litigation common to its businesses.
These cases are in various stages of development and, based on reports of
counsel, management believes that provisions made for potential losses relating
to such litigation are adequate and any further liabilities and costs will not
have a material adverse impact upon the Company's financial position or results
of operations.

                     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:
   
                                            N/12    
                          [(1+I/(1+J+0.005)]     - 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 charge.
    
 
     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)]     - 1
                                                     
                                                                 18/12
                                        =   [(1.07)/(1.08+0.005)]      - 1

                                        =   0.979335 - 1

                                        =   - 0.020665
</TABLE>
    
 
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%.

                                        =   + 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.

                                SEPARATE ACCOUNT

        Variable Separate Account was originally established by the Anchor
National Life Insurance Company (the "Company") on June 25, 1981, pursuant to
the provisions of California law, as a segregated asset account of the Company.
The separate account meets the definition of a "separate account" under the
federal securities laws and is registered with the Securities and Exchange
Commission (the "SEC") as a unit investment trust under the Investment Company
Act of 1940. This registration does not involve supervision of the management of
the separate account or the Company by the SEC.

        The assets of the separate account are the property of the Company.
However, the assets of the separate account, equal to its reserves and other
contract liabilities, are not chargeable with liabilities arising out of any
other business the Company may conduct. Income, gains, and losses, whether or
not realized, from assets allocated to the separate account are credited to or
charged against the separate account without regard to other income, gains, or
losses of the Company.

        The separate account is divided into Portfolios, with the assets of each
Portfolio invested in the shares of one of the underlying funds. The Company
does not guarantee the investment performance of the separate account, its
Portfolios or the underlying funds. Values allocated to the separate account and
the amount of variable annuity payments will vary with the values of shares of
the underlying funds, and are also reduced by contract charges.

        The basic objective of a variable annuity contract is to provide
variable annuity payments which will be to some degree responsive to changes in
the economic environment, including inflationary forces and changes in rates of
return available from various types of investments. The contract is designed to
seek to accomplish this objective by providing that variable annuity payments
will reflect the investment performance of the separate account with respect to
amounts allocated to it both before and after the Annuity Date. Since the
separate account is always fully invested in shares of the underlying funds, its
investment performance reflects the investment performance of those entities.
The values of such shares held by the separate account fluctuate and are subject
to the risks of changing economic conditions as well as the risk inherent in the
ability of the underlying funds' managements to make necessary changes in their
Portfolios to anticipate changes in economic conditions. Therefore, the owner
bears the entire investment risk that the basic objectives of the contract may
not be realized, and that the adverse effects of inflation may not be lessened.
There can be no assurance that the aggregate amount of variable annuity payments
will equal or exceed the Purchase Payments made with respect to a particular
account for the reasons described above, or because of the premature death of an
Annuitant.

        Another important feature of the contract related to its basic objective
is the Company's promise that the dollar amount of variable annuity payments
made during the lifetime of the Annuitant will not be adversely affected by the
actual mortality experience of the Company or by the actual expenses incurred by
the Company in excess of expense deductions provided for in the contract
(although the Company does not guarantee the amounts of the variable annuity
payments).

                                 GENERAL ACCOUNT

        The general account is made up of all of the general assets of the
Company other than those allocated to the separate account or any other
segregated asset account of the Company. A Purchase Payment may be allocated to
the one-year fixed investment option available in connection with the general
account, as elected by the owner at the time of purchasing a contract. Assets
supporting amounts allocated to fixed investment option become part of the
Company's general account assets and are available to fund the claims of all
classes of customers of the Company, as well as of its creditors. Accordingly,
all of the Company's assets held in the general account will be available to
fund the Company's obligations under the contracts as well as such other claims.

        The Company will invest the assets of the general account in the manner
chosen by the Company and allowed by applicable state laws regarding the nature
and quality of investments that may be made by life insurance companies and the
percentage of their assets that may be committed to any particular type of
investment. In general, these laws permit investments, within specified limits
and subject to certain qualifications, in federal, state and municipal
obligations, corporate bonds, preferred and common stocks, real estate
mortgages, real estate and certain other investments.


                                PERFORMANCE DATA

        From time to time the separate account may advertise the Cash Management
Portfolio's "yield" and "effective yield." Both yield figures are based on
historical earnings and are not intended to indicate future performance. The
"yield" of the Cash Management Portfolio refers to the net income generated for
a contract funded by an investment in the Portfolio (which invests in shares of
the Cash Management Portfolio of SunAmerica Trust) over a seven-day period
(which period will be stated in the advertisement). This income is then
"annualized." That is, the amount of income generated by the investment during
that week is assumed to be generated each week over a 52-week period and is
shown as a percentage of the investment. The "effective yield" is calculated
similarly but, when annualized, the income earned by an investment in the
Portfolio is assumed to be reinvested at the end of each seven day period. The
"effective yield" will be slightly higher than the "yield" because of the
compounding effect of this assumed reinvestment. Neither the yield nor the
effective yield takes into consideration the effect of any capital changes that
might have occurred during the seven day period, nor do they reflect the impact
of premium taxes or any withdrawal charges. The impact of other recurring
charges on both yield figures is, however, reflected in them to the same extent
it would affect the yield (or effective yield) for a contract of average size.

        In addition, the separate account may advertise "total return" data for
its other Portfolios. Like the yield figures described above, total return
figures are based on historical data and are not intended to indicate future
performance. The "total return" is a computed rate 

                                      -4-
<PAGE>   60

of return that, when compounded annually over a stated period of time and
applied to a hypothetical initial investment in a Portfolio made at the
beginning of the period, will produce the same contract value at the end of the
period that the hypothetical investment would have produced over the same period
(assuming a complete redemption of the contract at the end of the period).
Recurring contract charges are reflected in the total return figures in the same
manner as they are reflected in the yield data for contracts funded through the
Cash Management Portfolio. The effect of applicable withdrawal charges due to
the assumed redemption will be reflected in the return figures, but may be
omitted in additional return figures given for comparison.

        For periods starting prior to the date the contracts were first offered
to the public, the total return data for the Capital Appreciation, Growth,
Natural Resources and the Government and Quality Bond Portfolios of the separate
account will be derived from the performance of the corresponding Portfolios of
Anchor Trust, modified to reflect the charges and expenses as if the separate
account Portfolio had been in existence since the inception date of each
respective Anchor Trust Portfolio. Thus, such performance figures should not be
construed to be actual historic performance of the relevant separate account
Portfolio. Rather, they are intended to indicate the historic performance of the
four corresponding Portfolios of Anchor Trust, adjusted to provide direct
comparability to the performance of the Portfolios after the date the contracts
were first offered to the public (which will reflect the effect of fees and
charges imposed under the contracts). The Capital Appreciation, Growth, Natural
Resources and Government and Quality Bond Portfolios of Anchor Trust have served
since their inception as underlying investment media for separate accounts of
other insurance companies in connection with variable contracts not having the
same fee and charge schedules as those imposed under the contracts.

        Performance data for the various Portfolios are computed in the manner
described below.

CASH MANAGEMENT PORTFOLIO

   
        The annualized current yield and the effective yield for the Cash
Management Portfolio for the 7 day period ending November 30, 1997 were 3.74%
and 3.81%, respectively.
    

        Current yield is computed by first determining the Base Period Return
attributable to a hypothetical contract having a balance of one Accumulation
Unit at the beginning of a 7 day period using the formula:

             Base Period Return = (EV-SV-CAC)/(SV)

        where:

             SV = value of one Accumulation Unit at the start of a 7 day period

                                      -5-
<PAGE>   61

             EV = value of one Accumulation Unit at the end of the 7 day period

             CAC= an allocated portion of the $35 annual Contract
                  Administration Charge, prorated for 7 days

        The change in the value of an Accumulation Unit during the 7 day period
reflects the income received minus any expenses accrued, during such 7 day
period. The Contract Administration Charge (CAC) is first allocated among the
Portfolios and the general account so that each Portfolio's allocated portion of
the charge is proportional to the percentage of the number of accounts that have
money allocated to that Portfolio. The charge is further reduced, for purposes
of the yield computation, by multiplying it by the ratio that the value of the
hypothetical contract bears to the value of an account of average size for
contracts funded by the Cash Management Portfolio. Finally, as is done with the
other charges discussed above, the result is multiplied by the fraction 7/365 to
arrive at the portion attributable to the 7 day period.

        The current yield is then obtained by annualizing the Base Period
Return:

               Current Yield = (Base Period Return) x (365/7)

        The Cash Management Portfolio also quotes an "effective yield" that
differs from the current yield given above in that it takes into account the
effect of dividend reinvestment in the underlying fund. The effective yield,
like the current yield, is derived from the Base Period Return over a 7 day
period. However, the effective yield accounts for dividend reinvestment by
compounding the current yield according to the formula:

                                                          365/7
               Effective Yield = [(Base Period Return + 1)      - 1].

        Net investment income for yield quotation purposes will not include
either realized capital gains and losses or unrealized appreciation and
depreciation, whether reinvested or not. The yield quotations also do not
reflect any impact of premium taxes, transfer fees, or withdrawal charges.

        The yield quoted should not be considered a representation of the yield
of the Cash Management Portfolio in the future since the yield is not fixed.
Actual yields will depend not only on the type, quality and maturities of the
investments held by the underlying fund and changes in interest rates on such
investments, but also on factors such as an owner's account size (since the
impact of fixed dollar charges will be greater for small accounts than for
larger accounts).

        Yield information may be useful in reviewing the performance of the Cash
Management Portfolio and for providing a basis for comparison with other
investment alternatives. However, the Cash Management Portfolio's yield
fluctuates, unlike bank deposits or other investments that typically pay a fixed
yield for a stated period of time.

Portfolio compute their performance data as "total return".

        Total return for a Portfolio represents a single computed annual rate of
return that, when compounded annually over the time period shown and applied to
a hypothetical initial investment in a contract funded by that Portfolio made at
the beginning of the period, will produce the same contract value at the end of
the period that the hypothetical investment would have produced over the same
period. The total rate of return (T) is computed so that it satisfies the
formula:
                     n  
               P(1+T)  = ERV

        where: P =    a hypothetical initial payment of $1,000
               T =    average annual total return
               n =    number of years

            ERV  =    ending redeemable value of a hypothetical $1,000 payment
                      made at the beginning of the 1, 5, or 10 year period as of
                      the end of the period (or fractional portion thereof).

        The total return figures reflect the effect of both nonrecurring and
recurring charges, as discussed herein. Recurring charges are taken into account
in a manner similar to that used for the yield computations for the Cash
Management Portfolio, described above. The applicable withdrawal charge (if any)
is deducted as of the end of the period, to reflect the effect of the assumed
complete redemption. Because the impact of Contract Administration Charges on a
particular account will generally differ from that assumed in the computation,
due to differences between most actual allocations and the assumed one, as well
as differences due to varying account sizes, the total return experienced by an
actual Portfolio over the same time periods would generally have been different
from those produced by the computation. As with the Cash Management Portfolio
yield figures, total return figures are derived from historical data and are not
intended to be a projection of future performance.


                                ANNUITY PAYMENTS

INITIAL MONTHLY ANNUITY PAYMENTS

        The initial annuity payment is determined by applying separately that
portion of the contract value allocated to the fixed investment option and the
variable Portfolio(s), less any premium tax, and then applying it to the annuity
table specified in the contract for fixed and variable annuity payments. Those
tables are based on a set amount per $1,000 of proceeds applied. The appropriate
rate must be determined by the sex (except where, as in the case of certain
Qualified contracts and other employer-sponsored retirement plans, such
classification is not permitted) and age of the Annuitant and designated second
person, if any.

        The dollars applied are then divided by 1,000 and the result multiplied
by the appropriate annuity factor appearing in the table to compute the amount
of the first monthly annuity payment. In the case of a variable annuity, that
amount is divided by the value of an Annuity 

                                      -8-
<PAGE>   64

Unit as of the Annuity Date to establish the number of Annuity Units
representing each variable annuity payment. The number of Annuity Units
determined for the first variable annuity payment remains constant for the
second and subsequent monthly variable annuity payments, assuming that no
reallocation of contract values is made.

SUBSEQUENT MONTHLY PAYMENTS

        For fixed annuity payments, the amount of the second and each subsequent
monthly annuity payment is the same as that determined above for the first
monthly payment.

        For variable annuity payments, the amount of the second and each
subsequent monthly annuity payment is determined by multiplying the number of
Annuity Units, as determined in connection with the determination of the initial
monthly payment, above, by the Annuity Unit value as of the day preceding the
date on which each annuity payment is due.


                               ANNUITY UNIT VALUES

        The value of an Annuity Unit is determined independently for each
Portfolio.

        The annuity tables contained in the contract are based on a 3.5% per
annum assumed investment rate. If the actual net investment rate experienced by
a Portfolio exceed 3.5%, variable annuity payments derived from allocations to
that Portfolio will increase over time. Conversely, if the actual rate is less
than 3.5%, variable annuity payments will decrease over time. If the net
investment rate equals 3.5%, the variable annuity payments will remain constant.
If a higher assumed investment rate had been used, the initial monthly payment
would be higher, but the actual net investment rate would also have to be higher
in order for annuity payments to increase (or not to decrease).

        The payee receives the value of a fixed number of Annuity Units each
month. The value of a fixed number of Annuity Units will reflect the investment
performance of the Portfolios elected, and the amount of each annuity payment
will vary accordingly.

        For each Portfolio, the value of an Annuity Unit is determined by
multiplying the Annuity Unit value for the preceding month by the Net Investment
Factor for the month for which the Annuity Unit value is being calculated. The
result is then multiplied by a second factor which offsets the effect of the
assumed net investment rate of 3.5% per annum which is assumed in the annuity
tables contained in the contract.

NET INVESTMENT FACTOR

        The Net Investment Factor ("NIF") is an index applied to measure the net
investment performance of a Portfolio from one day to the next. The NIF may be
greater or less than or equal to one; therefore, the value of an Annuity Unit
may increase, decrease or remain the same.

        The NIF for any Portfolio for a certain month is determined by dividing
(a) by (b) where:

                                      -9-
<PAGE>   65

        (a)    is the Accumulation Unit value of the Portfolio  determined as 
               of the end of that month, and

        (b)    is the Accumulation Unit value of the Portfolio determined as of
               the end of the preceding month.

        The NIF for a Portfolio for a given month is a measure of the net
investment performance of the Portfolio from the end of the prior month to the
end of the given month. A NIF of 1.000 results from no change in the value of
the Portfolio; a NIF greater than 1.000 results from an increase in the value of
the Portfolio; and a NIF less than 1.000 results from a decrease in the value of
the Portfolio. The NIF is increased (or decreased) in accordance with the
increases (or decreases, respectively) in the value of a share of the underlying
fund in which the Portfolio invests; it is also reduced by separate account
asset charges.

        Illustrative Example

        Assume that one share of a given Portfolio had an Accumulation Unit
value of $11.46 as of the close of the New York Stock Exchange ("NYSE") on the
last business day in September; that its Accumulation Unit value had been $11.44
at the close of the NYSE on the last business day at the end of the previous
month. The NIF for the month of September is:

                      NIF = ($11.46/$11.44)

                          = 1.00174825

        Illustrative Example

        The change in Annuity Unit value for a Portfolio from one month to the
next is determined in part by multiplying the Annuity Unit value at the prior
month end by the NIF for that Portfolio for the new month. In addition, however,
the result of that computation must also be multiplied by an additional factor
that takes into account, and neutralizes, the assumed investment rate of 3.5
percent per annum upon which the annuity payment tables are based. For example,
if the net investment rate for a Portfolio (reflected in the NIF) were equal to
the assumed investment rate, the variable annuity payments should remain
constant (i.e., the Annuity Unit value should not change). The monthly factor
that neutralizes the assumed investment rate of 3.5 percent per annum is:

                         (1/12)
               1/[(1.035)      ] = 0.99713732

        In the example given above, if the Annuity Unit value for the Portfolio
was $10.103523 on the last business day in August, the Annuity Unit value on the
last business day in September would have been:

               $10.103523 x 1.00174825 x 0.99713732 = $10.092213

VARIABLE ANNUITY PAYMENTS

        Illustrative Example

        Assume that a male owner, P, owns a contract in connection with which P
has allocated all of his contract value to a single Portfolio. P is also the
sole Annuitant and, at age 60, has elected to annuitize his contract under
Option 4, a Life Annuity With 120 Monthly Payments Guaranteed. As of the last
valuation preceding the Annuity Date, P's Account was credited with 7543.2456
Accumulation Units each having a value of $15.432655, (i.e., P's account value
is equal to 7543.2456 x $15.432655 = $116,412.31). Assume also that the Annuity
Unit value for the Portfolio on that same date is $13.256932, and that the
Annuity Unit value on the day immediately prior to the second annuity payment
date is $13.327695.

        P's first variable annuity payment is determined from the annuity rate
tables in P's contract, using the information assumed above. From the tables,
which supply monthly annuity payments for each $1,000 of applied contract value,
P's first variable annuity payment is determined by multiplying the monthly
installment of $5.42 (Option 4 tables, male Annuitant age 60 at the Annuity
Date) by the result of dividing P's account value by $1,000:

             First Payment = $5.42 x ($116,412.31/$1,000) = $630.95

        The number of P's Annuity Units (which will be fixed; i.e., it will not
change unless he transfers his Account to another Account) is also determined at
this time and is equal to the amount of the first variable annuity payment
divided by the value of an Annuity Unit on the day immediately prior to
annuitization:

             Annuity Units = $630.95/$13.256932 = 47.593968

        P's second variable annuity payment is determined by multiplying the
number of Annuity Units by the Annuity Unit value as of the day immediately
prior to the second payment due date:

             Second Payment = 47.593968 x $13.327695 = $634.32

        The third and subsequent variable annuity payments are computed in a
manner similar to the second variable annuity payment.

        Note that the amount of the first variable annuity payment depends on
the contract value in the relevant Portfolio on the Annuity Date and thus
reflects the investment performance of the Portfolio net of fees and charges
during the Accumulation Phase. The amount of that payment determines the number
of Annuity Units, which will remain constant during the Income Phase (assuming
no transfers from the Portfolio). The net investment performance of the
Portfolio during the Income Phase is reflected in continuing changes during this
phase in the Annuity Unit value, which determines the amounts of the second and
subsequent variable annuity payments.

                                      TAXES

GENERAL

        Section 72 of the Internal Revenue Code of 1986, as amended (the "Code")
governs taxation of annuities in general. An owner is not taxed on increases in
the value of a contract until distribution occurs, either in the form of a
non-annuity distribution or as annuity payments under the annuity option
elected. For a lump sum payment received as a total surrender (total
redemption), the recipient is taxed on the portion of the payment that exceeds
the cost basis of the contract. For a payment received as a withdrawal (partial
redemption), federal tax liability is determined on a last-in, first-out basis,
meaning taxable income is withdrawn before the cost basis of the contract is
withdrawn. For contracts issued in connection with Non-qualified plans, the cost
basis is generally the Purchase Payments, while for contracts issued in
connection with Qualified plans there may be no cost basis. The taxable portion
of the lump sum payment is taxed at ordinary income tax rates. Tax penalties may
also apply.

        For annuity payments, the taxable portion is determined by a formula
which establishes the ratio that the cost basis of the contract bears to the
total value of annuity payments for the term of the annuity contract. The
taxable portion is taxed at ordinary income tax rates. Owners, Annuitants and
Beneficiaries under the contracts should seek competent financial advice about
the tax consequences of distributions under the retirement plan under which the
contracts are purchased.

        The Company is taxed as a life insurance company under the Code. For
federal income tax purposes, the separate account is not a separate entity from
the Company and its operations form a part of the Company.

WITHHOLDING TAX ON DISTRIBUTIONS

        The Code generally requires the Company (or, in some cases, a plan
administrator) to withhold tax on the taxable portion of any distribution or
withdrawal from a contract. For "eligible rollover distributions" from contracts
issued under certain types of Qualified plans, 20% of the distribution must be
withheld, unless the payee elects to have the distribution "rolled over" to
another eligible plan in a direct "trustee to trustee" transfer. This
requirement is mandatory and cannot be waived by the owner. Withholding on other
types of distributions can be waived.

        An "eligible rollover distribution" is the estimated taxable portion of
any amount received by a covered employee from a plan qualified under Section
401(a) or 403(a) of the Code, or from a tax-sheltered annuity qualified under
Section 403(b) of the Code (other than (1) annuity payments for the life (or
life expectancy) of the employee, or joint lives (or joint life expectancies) of
the employee and his or her designated Beneficiary, or for a specified period of
ten years or more; and (2) distributions required to be made under the Code).
Failure to "roll over" the entire amount of an eligible rollover distribution
(including an amount equal to the 20% portion of the distribution that was
withheld) could have adverse tax consequences, including the imposition of a
penalty tax on premature withdrawals, described later in this section.

                                      -12-
<PAGE>   68

        Withdrawals or distributions from a contract other than eligible
rollover distributions are also subject to withholding on the estimated taxable
portion of the distribution, but the owner may elect in such cases to waive the
withholding requirement. If not waived, withholding is imposed (1) for periodic
payments, at the rate that would be imposed if the payments were wages, or (2)
for other distributions, at the rate of 10%. If no withholding exemption
certificate is in effect for the payee, the rate under (1) above is computed by
treating the payee as a married individual claiming 3 withholding exemptions.

DIVERSIFICATION - SEPARATE ACCOUNT INVESTMENTS

        Section 817(h) of the Code imposes certain diversification standards on
the underlying assets of variable annuity contracts. The Code provides that a
variable annuity contract will not be treated as an annuity contract for any
period (and any subsequent period) for which the investments are not adequately
diversified, in accordance with regulations prescribed by the United States
Treasury Department ("Treasury Department"). Disqualification of the contract as
an annuity contract would result in imposition of federal income tax to the
owner with respect to earnings allocable to the contract prior to the receipt of
payments under the contract. The Code contains a safe harbor provision which
provides that annuity contracts such as the contracts meet the diversification
requirements if, as of the close of each calendar quarter, the underlying assets
meet the diversification standards for a regulated investment company, and no
more than 55% of the total assets consist of cash, cash items, U.S. government
securities and securities of other regulated investment companies.

        The Treasury Department has issued regulations which establish
diversification requirements for the investment portfolios underlying variable
contracts such as the contracts. The regulations amplify the diversification
requirements for variable contracts set forth in the Code and provide an
alternative to the safe harbor provision described above. Under the regulations
an investment portfolio will be deemed adequately diversified if (1) no more
than 55% of the value of the total assets of the portfolio is represented by any
one investment; (2) no more than 70% of the value of the total assets of the
portfolio is represented by any two investments; (3) no more than 80% of the
value of the total assets of the portfolio is represented by any three
investments; and (4) no more than 90% of the value of the total assets of the
portfolio is represented by any four investments. For purposes of determining
whether or not the diversification standards imposed on the underlying assets of
variable contracts by Section 817(h) of the Code have been met, "each United
States government agency or instrumentality shall be treated as a separate
issuer."

MULTIPLE CONTRACTS

        Multiple annuity contracts which are issued within a calendar year to
the same contract owner by one company or its affiliates are treated as one
annuity contract for purposes of determining the tax consequences of any
distribution. Such treatment may result in adverse tax consequences including
more rapid taxation of the distributed amounts from such multiple contracts. The
Company believes that Congress intended to affect the purchase of multiple
deferred annuity contracts which may have been purchased to avoid withdrawal
income tax 

                                      -13-
<PAGE>   69

treatment. Owners should consult a tax adviser prior to purchasing more than one
annuity contract in any calendar year.

TAX TREATMENT OF ASSIGNMENTS

        An assignment of a contract may have tax consequences, and may also be
prohibited by ERISA in some circumstances. Owners should therefore consult
competent legal advisers should they wish to assign their contracts.

QUALIFIED PLANS

        The contracts offered by this prospectus are designed to be suitable for
use under various types of Qualified plans. Taxation of owners in each Qualified
plan varies with the type of plan and terms and conditions of each specific
plan. Owners, Annuitants and Beneficiaries are cautioned that benefits under a
Qualified plan may be subject to the terms and conditions of the plan,
regardless of the terms and conditions of the contracts issued pursuant to the
plan.

        Following are general descriptions of the types of Qualified plans with
which the contracts may be used. Such descriptions are not exhaustive and are
for general information purposes only. The tax rules regarding Qualified plans
are very complex and will have differing applications depending on individual
facts and circumstances. Each purchaser should obtain competent tax advice prior
to purchasing a contract issued under a Qualified plan.

        Contracts issued pursuant to Qualified plans include special provisions
restricting contract provisions that may otherwise be available and described in
this prospectus. Generally, contracts issued pursuant to Qualified plans are not
transferable except upon surrender or annuitization. Various penalty and excise
taxes may apply to contributions or distributions made in violation of
applicable limitations. Furthermore, certain withdrawal penalties and
restrictions may apply to surrenders from Qualified contracts.

        (A)    H.R. 10 Plans

               Section 401 of the Code permits self-employed individuals to
establish Qualified plans for themselves and their employees, commonly referred
to as "H.R. 10" or "Keogh" Plans. Contributions made to the plan for the benefit
of the employees will not be included in the gross income of the employees until
distributed from the plan. The tax consequences to owners may vary depending
upon the particular plan design. However, the Code places limitations and
restrictions on all plans and such items as: amounts of allowable contributions;
form, manner and timing of distributions; vesting and nonforfeitability of
interests; nondiscrimination in eligibility and participation; and the tax
treatment of distributions, withdrawals and surrenders.

        (B)    Tax-Sheltered Annuities

               Section 403(b) of the Code permits the purchase of "tax-sheltered
annuities" by public schools and certain charitable, educational and scientific
organizations described in 

                                      -14-
<PAGE>   70

Section 501 (c)(3) of the Code. These qualifying employers may make
contributions to the contracts for the benefit of their employees. Such
contributions are not includible in the gross income of the employee until the
employee receives distributions from the contract. The amount of contributions
to the tax-sheltered annuity is limited to certain maximums imposed by the Code.
Furthermore, the Code sets forth additional restrictions governing such items as
transferability, distributions, nondiscrimination and withdrawals.

        (C)    Individual Retirement Annuities

               Section 408(b) of the Code permits eligible individuals to
contribute to an individual retirement program known as an "Individual
Retirement Annuity" ("IRA"). Under applicable limitations, certain amounts may
be contributed to an IRA which will be deductible from the individual's gross
income. These IRAs are subject to limitations on eligibility, contributions,
transferability and distributions. Sales of contracts for use with IRAs are
subject to special requirements imposed by the Code, including the requirement
that certain informational disclosure be given to persons desiring to establish
an IRA.

        (D)    Corporate Pension and Profit-Sharing Plans

               Section 401(a) and 401(k) of the Code permit corporate employers
to establish various types of retirement plans for employees. These retirement
plans may permit the purchase of the contracts to provide benefits under the
plan. Contributions to the plan for the benefit of employees will not be
includible in the gross income of the employee until distributed from the plan.
The tax consequences to owners may vary depending upon the particular plan
design. However, the Code places limitations on all plans on such items as
amount of allowable contributions; form, manner and timing of distributions;
vesting and nonforfeitability of interest; nondiscrimination in eligibility and
participation; and the tax treatment of distributions, withdrawals and
surrenders.

        (E)    Deferred Compensation Plans - Section 457

               Under Section 457 of the Code, governmental and certain other
tax-exempt employers may establish, for the benefit of their employees, deferred
compensation plans which may invest in annuity contracts. The Code, as in the
case of Qualified plans, establishes limitations and restrictions on
eligibility, contributions and distributions. Under these plans, contributions
made for the benefit of the employees will not be includible in the employees'
gross income until distributed from the plan. However, under a 457 plan all the
plan assets shall remain solely the property of the employer, subject only to
the claims of the employer's general creditors until such time as made available
to an owner or a Beneficiary.

                        REPORT OF INDEPENDENT ACCOUNTANTS


January 27, 1998



To the Board of Directors of Anchor National Life Insurance Company
and the Contractholders of its separate account,
Variable Separate Account (Portion Relating to the POLARIS Variable Annuity)


In our opinion, the accompanying statement of net assets, including the schedule
of portfolio investments, and the related statements of operations and of
changes in net assets present fairly, in all material respects, the financial
position of each of the Variable Accounts constituting Variable Separate Account
(Portion Relating to the POLARIS Variable Annuity), a separate account of Anchor
National Life Insurance Company (the "Separate Account") at November 30, 1997,
the results of their operations for the year then ended, and the changes in
their net assets for the two years then ended, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Separate Account's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these financial 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, which included confirmation of securities owned at November 30, 1997 by
correspondence with the custodian, provide a reasonable basis for the opinion
expressed above.

2. CHARGES AND DEDUCTIONS

   Charges and deductions are applied against the current value of the Separate
   Account and are paid as follows:

   WITHDRAWAL CHARGE: The contract value may be withdrawn at any time during the
   accumulation period. Purchase payments that are no longer subject to the
   withdrawal charge and not previously withdrawn and earnings in the contract
   may be withdrawn free of withdrawal charges at any time. In addition, there
   is a free withdrawal amount for the first withdrawal during a contract year
   after the first contract year. The free withdrawal amount is the greater of
   earnings in the contract or 10% of the purchase payments that have been
   invested for at least one year, and not withdrawn, less any withdrawals made
   during the year. Should a withdrawal exceed the free withdrawal amount, a
   withdrawal charge, in certain circumstances, is imposed and paid to the
   Company.

   Withdrawal charges vary in amount depending upon the number of years since
   the purchase payment being withdrawn was made. The withdrawal charge is
   deducted from the remaining contract value so that the actual reduction in
   contract value as a result of the withdrawal will be greater than the
   withdrawal amount requested and paid. For purposes of determining the
   withdrawal charge, withdrawals will be allocated first to investment income,
   if any (which may generally be withdrawn free of a withdrawal charge), and
   then to the oldest purchase payments first so that all withdrawals are
   allocated to purchase payments to which the lowest (if any) withdrawal charge
   applies.

   Any amount withdrawn which exceeds a free withdrawal may be subject to a
   withdrawal charge in accordance with the withdrawal charge table shown below:

2.  CHARGES AND DEDUCTIONS (continued)

    CONTRACT MAINTENANCE FEE: An annual contract maintenance fee of $35 ($30 in
    North Dakota and Utah) is charged against each contract, which reimburses
    the Company for expenses incurred in establishing and maintaining records
    relating to a contract. The contract maintenance fee will be assessed on
    each anniversary during the accumulation phase. In the event that a total
    surrender of contract value is made, the entire charge will be assessed as
    of the date of surrender.

    TRANSFER FEE: A transfer fee of $25 ($10 in Pennsylvania and Texas) is
    assessed on each transfer of funds in excess of fifteen transactions within
    a contract year.

    PREMIUM TAXES: Premium taxes or other taxes payable to a state or other
    governmental entity will be charged against the contract values. Some states
    assess premium taxes at the time purchase payments are made; others assess
    premium taxes at the time annuity payments begin. The Company currently
    intends to deduct premium taxes at the time of surrender or upon
    annuitization; however, it reserves the right to deduct any premium taxes
    when incurred or upon the payment of the death benefit.

    MORTALITY AND EXPENSE RISK CHARGE: The Company deducts mortality and expense
    risk charges, which total to an annual rate of 1.37% of the net asset value
    of each portfolio, computed on a daily basis. The mortality risk charge is
    compensation for the mortality risks assumed by the Company from its
    contractual obligations to make annuity payments after the contract has
    annuitized for the life of the annuitant and to provide 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.

    DISTRIBUTION EXPENSE CHARGE: The Company deducts a distribution expense
    charge at an annual rate of 0.15% of the net asset value of each portfolio,
    computed on a daily basis. 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, the Company will bear the loss.

    SEPARATE ACCOUNT INCOME TAXES: The Company currently does not maintain a
    provision for taxes, but has reserved the right to establish such a
    provision for taxes in the future if it determines, in its sole discretion,
    that it will incur a tax as a result of the operation of the Separate
    Account.

        Registrant undertakes to (1) file post-effective amendments to this

        the contract specifically to bring the redemption restrictions imposed

                             DISTRIBUTION AGREEMENT
                             ----------------------


         THIS AGREEMENT, entered into as of this 6th day of August, 1993, by and
between ANCHOR NATIONAL LIFE INSURANCE COMPANY ("Anchor"), a life insurance
company organized under the laws of the State of California, on behalf of itself
and VARIABLE SEPARATE ACCOUNT ("Separate Account"), a Separate Account
established by Anchor pursuant to the insurance laws of the State of California,
and SUNAMERICA CAPITAL SERVICES, INC., ("Distributor"), a corporation organized
under the laws of the state of Delaware.

                                   WITNESSETH:

         WHEREAS, Anchor issues to the public certain variable annuity contracts
identified on the contract specification sheet attached hereto as Attachment
A ("Contracts"), which Contracts are currently distributed by SunAmerica
Securities, Inc. and Royal Alliance Associates, Inc.; and

         WHEREAS, Anchor, by resolution adopted on June 25, 1981, established
the Separate Account on its books of account, for the purpose of issuing
variable annuity contracts; and

         WHEREAS, the Separate Account is registered with the Securities and
Exchange Commission ("Commission") as a unit investment trust under the
Investment Company Act of 1940 (File No. 811-3959); and

         WHEREAS, the Contracts to be issued by Anchor are registered with the
Commission under the Securities Act of 1933 (the "Act") (File No. 33-47472) for
offer and sale to the public, and otherwise are in compliance with all
applicable laws; and

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

         WHEREAS, Anchor desires to obtain the services of the Distributor as
distributor of said Contracts issued by Anchor through the Separate Account to
replace SunAmerica Securities, Inc. and Royal Alliance Associates, Inc.;

         NOW THEREFORE, in consideration of the foregoing, and of the mutual
covenants and conditions set forth herein, and for other good and valuable
consideration, Anchor, the Separate Account, and Distributor hereby agree as
follows:

<PAGE>   2
         1.       The Distributor will serve as distributor on an agency basis
         for the Contracts which will be issued by Anchor through the Separate
         Account.

         2.       The Distributor will, either directly or through an affiliate,
         provide information and marketing assistance to licensed insurance
         agents and broker-dealers on a continuing basis. The Distributor shall
         be responsible for compliance with the requirements of state
         broker-dealer regulations and the Securities Exchange Act of 1934 as
         each applies to Distributor in connection with its duties as
         distributor of said Contracts. Moreover, the Distributor shall conduct
         its affairs in accordance with the Rules of Fair Practice of the
         National Association of Securities Dealers, Inc.

         3.       Subject to the agreement of Anchor, the Distributor may enter
         into dealer agreements with broker-dealers registered under the
         Securities Exchange Act of 1934 and authorized by applicable law to
         sell variable annuity contracts issued by Anchor through the Separate
         Account. Any such contractual arrangement is expressly made subject to
         this Agreement, and the Distributor will at all times be responsible to
         Anchor for purposes of the federal securities laws for the distribution
         of Contracts issued through the Separate Account. The Distributor
         expressly assumes any dealer agreements entered into by SunAmerica
         Securities, Inc. and Royal Alliance Associates, Inc. with respect to
         the Contracts.

         4.       Warranties

                  (a)      Anchor represents and warrants to the Distributor
                  that:

                           applicable, Form S-1) for each of the Contracts
                           identified on Attachment A have been filed with the
                           Commission in the form previously delivered to the
                           Distributor and that copies of any and all amendments
                           thereto will be forwarded to the Distributor at the
                           time that they are filed with the Commission;

                           (ii)   The Registration Statement and any further
                           amendments or supplements thereto will, when they
                           become effective, conform in all material respects to
                           the requirements of the Securities Act of 1933 and

                           regulations of the Commission under such Acts, and
                           will not contain an untrue statement of a material
                           fact or omit to state a material fact required to be

                           or conducts any business, so as to require such
                           qualification;

                           (iv)   The Contracts to be issued through the

                           contained in the Prospectuses relating thereto;

                           (v)    Those persons who offer and sell the Contracts

                           consummation of the transactions contemplated by this

                           transactions contemplated by this Agreement, except
                           such as may be required under the Securities Exchange
                           Act of 1934 or state insurance or securities laws in
                           connection with the distribution of the Contracts by
                           the Distributor; and

                           (vii)  There are no material legal or governmental
                           proceedings pending to which Anchor or the Separate
                           Account is a party or of which any property of Anchor
                           or the Separate Account is the subject, other than as
                           set forth in the Prospectus relating to the
                           Contracts, and other than litigation incident to the
                           kind of business conducted by Anchor, if determined
                           adversely to Anchor, would individually or in the
                           aggregate have a material adverse effect on the
                           financial position, surplus or operations of Anchor.

                  (b)      The Distributor represents and warrants to Anchor
                  that:

                           (i)    It is a broker-dealer duly registered with the
                           Commission pursuant to the Securities Exchange Act of
                           1934 and a member in good standing of the National
                           Association of Securities Dealers, Inc., and is in
                           compliance with the securities laws in those states
                           in which it conducts business as a broker-dealer;

                           (ii)   The performance of this Agreement and the
                           consummation of the transactions herein contemplated
                           will not result in a breach or violation of any of
                           the terms or provisions of or constitute a default
                           under any statute, any indenture, mortgage, deed of
                           trust, note agreement or other agreement or
                           instrument to which the Distributor is a party or by
                           which the Distributor is bound, the Certificate of
                           Incorporation or Bylaws of the Distributor, or any
                           order, rule or regulation of any court or
                           governmental agency or body having jurisdiction over
                           the Distributor or its property; and

                           (iii)  To the extent that any statements or omissions
                           made in the Registration Statement, or any amendment
                           or supplement thereto are made in reliance upon and
                           in conformity with written information furnished to
                           Anchor by the Distributor expressly for use therein,
                           such Registration Statement and any amendments or
                           supplements thereto will, when they become effective
                           or are filed with the Commission, as the case may be,
                           conform in all material respects to the requirements
                           of the Securities Act of 1933 and the rules and
                           regulations of the Commission thereunder and will not
                           contain any untrue statement of a material fact or
                           omit to state any material fact

                           required to be stated therein or necessary to make
                           the statements therein not misleading.

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

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

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

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

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

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



                                      - 5 -

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

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

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

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

         15.       Anchor agrees to advise the Distributor immediately of:

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

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

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

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

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

         18.       This Agreement will terminate automatically upon its
         assignment to any person other than a person which is a


                                      - 6 -

         wholly owned subsidiary of SunAmerica Inc. This Agreement shall
         terminate, without the payment of any penalty by either party:

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

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

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

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

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

         20.      (a)      Anchor will indemnify and hold harmless the
         Distributor and each person, if any, who controls the Distributor
         within the meaning of the Act against any losses, claims, damages or
         liabilities to which the Distributor or such controlling person may
         become subject, under the Act or otherwise, insofar as such losses,
         claims, damages or liabilities (or actions in respect thereof) arise
         out of or are based upon any untrue statement or alleged untrue
         statement of a material fact contained in the Registration Statement,
         Prospectus or Statement of Additional Information or any other written
         sales material prepared by Anchor which is utilized by the Distributor
         in connection with the sale of Contracts or arise out of or are based
         upon the omission or alleged omission to state therein a material fact
         required to be stated therein or (in the case of the Registration
         Statement, Prospectus and Statement of Additional Information)
         necessary to make the statement therein not misleading or (in the case
         of such other sales material) necessary to make the statement therein
         not misleading or (in the case of such other sales material) necessary
         to make the statements therein not misleading in the light of the
         circumstances under which they were made and will reimburse the
         Distributor and each such controlling

         person for any legal or other expenses reasonably incurred by the
         Distributor or such controlling person in connection with investigating
         or defending any such loss, claim, damage, liability or action,
         provided, however, that Anchor will not be liable in any such case to
         the extent that any such loss, claim, or omission or alleged omission
         made in such Registration Statement, Prospectus or Statement of
         Additional Information in conformity with information furnished to
         Anchor specifically for use therein; and provided, further, that
         nothing herein shall be so construed as to protect the Distributor
         against any liability to Anchor or the Contract Owners to which the
         Distributor would otherwise be subject by reason of willful
         misfeasance, bad faith or gross negligence, in the performance of its
         duties, or by reason of the reckless disregard by the Distributor of
         its obligations and duties under this Agreement.

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

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

         22.      This Agreement covers and includes all agreements, verbal and
         written, between Anchor and the Distributor with regard to the
         marketing and distribution of the Contracts, and supersedes and annuls
         any and all agreements between the parties with regard to the
         distribution of the Contracts; except that this Agreement shall not
         affect the operation of previous or future agreements entered into
         between Anchor and the Distributor unrelated to the sale of the
         Contracts.

                                SELLING AGREEMENT

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


This SELLING AGREEMENT ("Agreement"), dated _____________________, is by and
among ANCHOR NATIONAL LIFE INSURANCE COMPANY ("Insurer"), SUNAMERICA CAPITAL
SERVICES, INC. ("Distributor") and ___________________________________________,
together with its duly licensed insurance affiliates indicated on the attached
Annex I (the "Affiliates" and collectively, "Broker/Dealer").

Where permitted by state law, Broker/Dealer is acting as general agent hereunder
and shall be responsible for the duties of broker/dealer and general agent
hereunder. If state law does not permit Broker/Dealer to hold a corporate
insurance license, the appropriate duly licensed insurance affiliate identified
on Annex I shall act as general agent hereunder. Upon execution of Annex I, such
entity or entities agree to be bound by the terms hereof as if it were included
in the definition of Broker/Dealer.

1.      Appointment. This Agreement is for the purpose of arranging for the
        distribution of certain variable and fixed annuity contracts and any
        other life insurance products identified on Exhibit 1 (the "Contracts"),
        issued by the Insurer and, in the case of variable contracts, for which
        Distributor is distributor, through sales people who are licensed agents
        of the Insurer for insurance purposes, are associated with and
        registered representatives of Broker/Dealer (each, a "Subagent"). In
        consideration of the mutual promises and covenants contained in this
        Agreement, the Insurer and Distributor each appoint Broker/Dealer and,
        as provided in Section 3, its Subagents, to solicit and procure
        applications for the Contracts. This appointment is not deemed to be
        exclusive in any manner and only extends to those jurisdictions where
        the Contracts have been approved for sale and in which Insurer and
        Broker/Dealer are both licensed as required by prevailing regulatory
        requirements.

2.      Representations and Warranties.

        A.      Each party hereto represents and warrants to each other party,
                as follows:

                (i) It is duly organized, validly existing and in good standing
                under the laws of the state of its incorporation or other
                corresponding applicable law and has all requisite power,
                corporate or otherwise to carry on its business as now being
                conducted and to perform its obligations as contemplated by this

        responsible for investigating the character, work experience and
        background of any proposed Subagent prior to recommending appointment by
        Insurer. No Subagent shall act on behalf of Insurer until properly
        appointed by Insurer. To the extent that Exhibit 1 does not include all
        annuity Contracts of Insurer which are registered as securities under
        the Federal Securities laws, Broker/Dealer is responsible for ensuring
        that its Subagents, unless otherwise agreed to with Insurer in writing,
        do not offer to sell any other variable annuity contracts issued by
        Insurer, other than the Contracts, unless a selling agreement with
        respect thereto has been executed by the parties. Broker/Dealer is
        responsible for supervising the activities of its Subagents and for
        ensuring that Subagents are properly licensed and in compliance with all
        applicable federal, state and local laws and regulations and all rules
        and procedures of Insurer. Broker/Dealer shall notify Insurer promptly,
        in writing, of any giving or receiving of notice of termination of any
        subagent. Insurer reserves the right to refuse to appoint any proposed
        Subagent and to terminate any relationship with any Subagent, with or
        without cause, at any time. By submitting a Subagent for appointment,
        Broker/Dealer warrants that: (1) such Subagent is recommended for

        to transact business with Insurer and is a duly registered
        representative of Broker/Dealer; and (3) all background investigations

                material (including prepared scripts for oral presentations) in
                connection with the sales of the Contracts or solicitations
                hereof, unless such material has been provided by, or approved
                in writing in advance of uch use by, the Insurer and
                Distributor.

                distribution of any such sales material. This material shall be
                made available to appropriate federal and state regulatory
                agencies as required by law or regulation and to Distributor and
                Insurer upon written request.

        currently effective prospectuses for the Contract and the underlying
        funds; and if required by state law, the Statement of Additional
        Information for the Contract; that the prospectuses will be delivered
        concurrently with each sales presentation and that no statements shall
        be made to a client superseding or controverting or otherwise
        inconsistent with any statement made in the prospectus. The Insurer and
        Distributor shall furnish Broker/Dealer, at no cost to such party,
        reasonable quantities of currently effective prospectuses.

6.      Conduct of Business.

        A.      Broker/Dealer will fully comply with the requirements of all
                applicable laws, rules and regulations of regulatory authorities
                (including self-regulatory organizations) having jurisdiction
                over the activities of Broker/Dealer or over the activities
                contemplated by this Agreement to be conducted by Broker/Dealer.

        B.      Neither Broker/Dealer nor any Subagent shall solicit an
                application from, or recommend the purchase of a Contract to, an
                applicant without having reasonable grounds to believe, in
                accordance with, among other things, applicable regulations of
                any state insurance commission, the Securities and Exchange
                Commission ("SEC") and the NASD, that such purchase is suitable
                for the applicant. While not limited to the following, a
                determination of suitability shall be based on information
                supplied after a reasonable inquiry concerning the applicant's
                insurance and investment objectives and 


<PAGE>   4

                financial situation and needs.

        C.      Broker/Dealer has or will have established, prior to its
                commencement of any solicitation of sales of Contracts pursuant
                to the terms of this Agreement, such rules, procedures,
                supervisory and inspection techniques as necessary to diligently
                supervise the activities of its Subagents pursuant to this
                Agreement and to ensure compliance with the terms of this
                Agreement necessary to establish diligent supervision.
                Broker/Dealer shall be responsible for securities training,
                supervision and control of its Subagents in connection with
                their solicitation activities with respect to the Contracts and
                shall supervise compliance with applicable federal and state
                securities laws and NASD requirements in connection with such
                solicitation activities. Broker/Dealer will observe, and will
                comply with, all requirements of any bank on whose premises
                Broker/Dealer engages in sales activities pursuant to this
                Agreement. Upon request by Insurer or Distributor, Broker/Dealer
                will furnish appropriate records as are necessary to establish
                diligent supervision.

        D.      Broker/Dealer will fully comply with the requirements of
                applicable state insurance laws and regulations and will
                maintain all books and records and file all reports required
                thereunder to be maintained or filed by a licensed insurance
                agent. Broker/Dealer shall comply with the terms and conditions
                of any letter issued by the Staff of the SEC with respect to the
                non-registration as a broker-dealer under the 1934 Act of a
                corporation licensed as an insurance agent and associated with a
                registered broker-dealer. Broker/Dealer shall notify Distributor
                immediately in writing if Broker/Dealer fails to comply with any
                such terms and conditions and shall take such measures as may be
                necessary to comply with any such terms and conditions.

        E.      Broker/Dealer shall promptly notify Insurer and Distributor of
                any written customer complaint or notice of any regulatory
                investigation or proceeding received by Broker/Dealer or any
                Subagent relating to a Contract or any activities undertaken in
                connection with this Agreement. Insurer and Broker/Dealer shall
                each cooperate fully in any investigation or proceeding
                including but not limited to any securities or insurance
                regulatory investigation or proceeding or judicial proceeding
                arising in connection with the Contracts.

        F.      Broker/Dealer shall pay all expenses incurred by it in the
                performance of this Agreement unless otherwise specifically
                provided for in this Agreement or in a writing signed by Insurer
                and/or Distributor and Broker/Dealer.

        G.      Applications shall be taken only on preprinted application forms
                supplied by the Insurer. The Contract forms and applications are
                the sole property of the Insurer. No person other than the
                Insurer has the authority to make, alter or discharge any
                policy, Contract application, Contract certificate, supplemental
                contract or form issued by the Insurer. No person other than the
                Insurer has the right to waive any provision with respect to any
                Contract or policy. No person other than the Insurer has the
                authority to enter into any proceeding in a court of law or
                before a regulatory agency in the name of or on behalf of the
                Insurer.

        H.      Broker/Dealer and Subagent shall accept premiums in the form of
                a check or money order made payable to Insurer. Broker/Dealer
                shall ensure that all checks and money orders and applications
                for the Contracts received by it or any Subagent are remitted
                promptly to Insurer. In the event that any other premiums are
                sent to a Subagent or Broker/Dealer rather than to Insurer, they
                shall promptly remit such premiums to Insurer. Broker/Dealer
                acknowledges that if any premium is held at any time by it, such
                premium shall be held on behalf of Insurer, and Broker/Dealer
                shall segregate such premium from its own funds and promptly
                remit such premium to Insurer. All such premiums, whether by
                check, money order or wire, shall at all times be the property
                of Insurer.

        I.      Upon issuance of a Contract by Insurer and delivery of such
                Contract to Broker/Dealer, Broker/Dealer shall promptly deliver
                such Contract to its purchaser. For purposes of this provision,
                "promptly" shall be deemed to mean not later than five calendar
                days, or such 


<PAGE>   5

                shorter period as is reasonable under the circumstances.
                Broker/Dealer shall return promptly to Insurer all receipts for
                delivered Contracts, all undelivered Contracts and all receipts
                for cancellation, in accordance with the instructions from
                Insurer.

        J.      Unless required by a determination of suitability, during the
                term of this Agreement and after termination hereof,
                Broker/Dealer covenants on behalf of itself and any Subagent
                appointed hereunder, that they shall not solicit, induce or
                attempt to solicit or induce Contract owners to terminate,
                surrender, cancel, replace or exchange such Contract.
                Broker/Dealer acknowledges and agrees that the provisions
                contained in this Section 6 may be enforced by an action for an
                injunction, as well as or in addition to any action for damages.

7.      Commission Payments.

        A.      Broker/Dealer shall be entitled to receive a commission based
                upon premiums received and accepted by the Insurer for Contracts
                issued pursuant to this Agreement, based on the applicable rate
                of commission set forth in the Commission Schedule attached
                hereto as Exhibit 1 which is incorporated herein by reference.
                Broker/Dealer shall be solely responsible for the payment of any
                commission or consideration of any kind to Subagents.

        B.      In no event shall the Insurer be liable for the payment of any
                commissions with respect to any solicitation made, in whole or
                in part, by any person not appropriately licensed and registered
                prior to the commencement of such solicitation.

        C.      If a Contract is returned to the Insurer pursuant to the "Free
                Look" provision or any other right to examine provision of the
                Contract, the full commission paid by the Insurer will be
                unearned and shall be returned to the Insurer upon demand or, in
                the absence of such demand, charged back to the recipient of the
                commission. Broker/Dealer covenants and agrees to promptly
                deliver Contracts and to hold the Insurer harmless from and
                against any claim arising from market loss resulting from their
                breach of this covenant.

        D.      In no event shall Insurer incur obligations under this Agreement
                to issue any Contracts or pay any commission in connection
                therewith if the Contract owner is over the maximum issue age
                with respect to that product when the Contract application was
                accepted. With respect to such Contracts, the full commission
                paid by the Insurer will be unearned and shall be returned to
                the Insurer upon demand or, in the absence of such demand,
                charged back to the recipient of the commission.

        E.      With respect to any Contract that is rescinded, as determined by
                the Insurer in its sole discretion (other than a rescission with
                respect to which a surrender charge applies), or if the Insurer
                otherwise determines that a commission has not been earned (but
                such determination may not contravene any other provision of
                this Agreement), 100% of such unearned commission will be
                returned to the Insurer upon demand or, in the absence of such
                demand, charged back to the recipient of the commission.

        F.      Compensation for the sale of any Contract which is renewed,
                changed, exchanged or otherwise converted from any other
                contract issued by the Company shall be paid according to the
                Insurer's guidelines and practices.

        G.      With respect to any Contract, or group of Contracts which the
                Insurer in its sole discretion deems to be a single case, and
                which at the time of application submission the initial purchase
                payment is greater than $500,000, the Insurer may determine in
                its sole discretion that the commissions set forth on Exhibit 1
                not apply. In the event the Insurer determines that the
                commission(s) do not apply, the Insurer may establish an
                alternate commission for such Contract or Contracts.

8.      Indemnification

        A.      Broker/Dealer shall indemnify, defend and hold harmless Insurer
                and Distributor and 


<PAGE>   6

                each person who controls or is associated with Insurer or
                Distributor within the meaning of the federal securities laws
                and any director, officer, corporate agent, employee, attorney
                and any representative thereof, from and against all losses,
                expenses, claims, damages and liabilities (including any costs
                of investigation and legal expenses and any amounts paid in
                settlement of any action, suit or proceeding of any claim
                asserted) which result from, arise out of or are based upon:

        (i)     any breach by Broker/Dealer or its Affiliates of any
                representation, warranty or other provision of this Agreement,
                including any acts or omissions of Broker/Dealer, Affiliates,
                Subagents and other associated persons; or

        (ii)    any violation by Broker/Dealer, any Affiliate or any Subagent of
                any federal or state securities law or regulation, insurance law
                or regulation or any rule or requirement of the NASD;

        (iii)   the use by Broker/Dealer, any Affiliate or any Subagent of any
                sales or promotional material which has not received specific
                written approval of Insurer and Distributor as provided in
                Section 4 of this Agreement, any oral or written
                misrepresentations or any unlawful sales practices concerning
                the Contracts by Broker/Dealer, any Affiliate or any Subagent;
                or

        (iv)    Claims by Subagents or other agents or representatives of
                Broker/Dealer for commissions or other compensation or
                remuneration of any type.

        B.      The indemnification provided for herein shall survive
                termination of this Agreement.

9.      Fidelity Bond. Broker/Dealer represents that all directors, officers,
        employees, representatives and/or Subagents who are appointed pursuant
        to this Agreement or who have access to funds of the Insurer are and
        will continue to be covered by a blanket fidelity bond including
        coverage for larceny, embezzlement or any other defalcation, issued by a
        reputable bonding company. This bond shall be maintained at
        Broker/Dealer's expense. Such bond shall be at least equivalent to the
        minimal coverage required under the NASD Rules of Fair Practice,
        endorsed to extend coverage to life insurance and annuity transactions.
        Broker/Dealer acknowledges that the Insurer may require evidence that
        such coverage is in force and Broker/Dealer shall promptly give notice
        to the Insurer of any notice of cancellation or change of coverage.
        Broker/Dealer assigns any proceeds received from the fidelity bond
        company to the Insurer to the extent of the Insurer's loss due to
        activities covered by the bond. If there is any deficiency,
        Broker/Dealer will promptly pay the Insurer that amount on demand, and
        Broker/Dealer shall indemnify and hold harmless the Insurer from any
        deficiency and from the cost of collection.

10.     Market Timer Program. Insurer has available a Market Timer Program which
        allows a market timer service to effect multiple transfers or other
        transactions. Parties may use this program at the discretion of Insurer
        and upon execution of a Market Timer Agreement. Among other provisions,
        the Market Timer Agreement specifies that if the impact of processing
        exchange transactions received from all outside sources is deemed to be
        injurious to one of the separate accounts or a subaccount thereof, then
        Insurer in its sole discretion may elect not to process the exchanges
        and that Insurer will notify the Market Timer Service of the inability
        to process the requested exchange. Insurer reserves the right to
        terminate participation in or the entire Market Timer Program at any
        time and for any reason.

11.     RapidApp Program. If applications are transmitted to the Insurer
        pursuant to the Insurer's RapidApp Program, the following provisions
        shall apply to such applications and Contracts issued pursuant to the
        RapidApp Program.

        A.      Broker/Dealer agrees to communicate with owners of the Contracts
                issued through the RapidApp Program in order to obtain and
                deliver to the Insurer the signed confirmation for the Contract.
                Broker/Dealer further agrees to provide any assistance or
                cooperation required to enforce a Contract issued under the
                RapidApp Program which shall include, but not be limited to,
                providing the Insurer access to recordings of telephone
                conversations with customers containing their consent to the
                purchase of Contracts, or 


<PAGE>   7

                providing statements or affidavits from such Subagents as to the
                customer's consent to the making of the Contract.

        B.      In the event the owner of a Contract repudiates or rescinds the
                Contract and the Insurer, in its sole discretion, waives any
                surrender charges, the full commission paid by the Insurer will
                be returned to the Insurer upon demand or, in the absence of
                such demand, charged back to the recipient of the commission. In
                addition, all amounts equal to any market loss arising from such
                rescission or repudiation will be paid by Broker/Dealer on
                demand, or in the absence of such demand, charged back to
                Broker/Dealer.

        C.      Broker/Dealer agrees that it will be solely responsible for the
                transmission or failure of transmission of application
                information to the Insurer. Broker/Dealer warrants that all
                application information will be accurate and can be relied upon
                by the Insurer.

        D.      Broker/Dealer agrees to pay the Insurer all amounts equal to any
                market loss resulting from the misallocation of the initial
                purchase payment into the subaccounts, which misallocation was
                the result of Insurer relying on Broker/Dealer's or their
                Subagents' application information. In the absence of a demand
                for payment, such amounts shall be charged back to
                Broker/Dealer.

        E.      Broker/Dealer agrees that its Subagents who are resident and
                licensed in those jurisdictions approved by the Insurer may
                submit applications to the Insurer pursuant to the RapidApp
                Program and agree to the provisions of this Section 11.
                Broker/Dealer acknowledges that agreeing to the provisions of
                this Section 11 does not require its Subagents to submit all
                applications to the Insurer pursuant to the RapidApp Program.

12.     Termination.

        A.      Normal Termination. This Agreement shall continue for an
                indefinite term, subject to the termination by either party upon
                written notice to the other parties hereto, which shall be
                effective upon receipt thereof. In addition, Insurer may
                terminate this Agreement without notice if Broker/Dealer fails
                to satisfy the Insurer's production requirements, as determined
                in the sole discretion of the Insurer.

        B.      Automatic Termination for Cause. This Agreement shall
                automatically terminate upon: (1) a material breach of this
                Agreement, including without limitation the failure to comply
                with the laws or regulations of any state or other governmental
                agency or body having jurisdiction over the sale of insurance;
                and (2) the suspension, revocation or non-renewal of any then
                required insurance or securities license of Broker/Dealer or any
                of its Affiliates, or the deregistration of the Broker/Dealer or
                its termination of membership with the NASD.

        C.      Rights and Obligations. Upon termination of this Agreement,
                except as otherwise provided herein, all authorizations, rights
                and obligations shall cease. If this Agreement is terminated for
                cause as described above, Broker/Dealer's right to receive
                compensation shall immediately terminate.

13.     General Provisions.

        A.      Waiver. Waiver by any of the parties to promptly insist upon
                strict compliance with any of the obligations of any other party
                under this Agreement will not be deemed to constitute a waiver
                of the right to enforce strict compliance.

        B.      Independent Contractor. Broker/Dealer is an independent
                contractor and its Subagents who are appointed as insurance
                agents of Insurer are agents of Broker/Dealer and not employees,
                agents or representatives of Insurer or Distributor.

        C.      Independent Assignment. No assignment of this Agreement or of
                commissions or other payments under this Agreement shall be

                               Commission Schedule

This Commission Schedule is hereby incorporated in and made a part of the
Selling Agreement dated as of _________________________ ("Agreement") by and
between Anchor National Life Insurance Company ("Insurer"), SunAmerica Capital
Services, Inc. and __________________________________ together with its duly
licensed insurance affiliates indicated on Annex I to the Agreement
(collectively, "Broker/Dealer").

1. In no event shall the Insurer be liable for the payment of any commissions
with respect to any solicitation made, in whole or in part, by any person not
appropriately licensed and registered prior to the commencement of such
solicitation.

2. If a Contract is returned to the Insurer pursuant to the "Free Look"
provision or any other right to examine provision of the Contract, the full
commission paid by the Insurer will be unearned and shall be returned to the
Insurer upon demand or, in the absence of such demand, charged back to the
recipient of the commission.

3. With respect to any Contract that is rescinded, as determined by the Insurer
in its sole discretion (other than a rescission with respect to which a
surrender charge applies), or if the Insurer otherwise determines that a
commission has not been earned (but such determination may not contravene any
other provision of this Agreement), 100% of such unearned commission will be
returned to the Insurer upon demand or, in the absence of such demand, charged
back to the recipient of the commission.

4. The following commission rates shall apply to Contracts issued by Insurer.
Commissions are paid in respect of the aggregate purchase payments received and
accepted by the Insurer with complete application information and documentation
as required by the Insurer or as a subsequent purchase payment under a Contract
after the Contract is in force. In addition, if an annual trail commission is
applicable, it will be payable in quarterly installments. The trail commission
installment for each calendar quarter will be calculated based on the Contract
Value as of the end of such quarter. Trail commissions are not payable on any
Contract that has been surrendered, annuitized or under which a death benefit
has been paid.

AMERICAN PATHWAY II CONTRACTS. Commissions will be paid in the amount of
five-and-one-half percent (5.5%). Commissions are paid only on the subsequent
purchase payments received and accepted by the Insurer under a contract which is
in force.

ICAP II CONTRACTS.  Commissions will be paid in the amount of five percent (5%).

ICAP II GROUP CONTRACTS. Commissions will be paid in the amount of five percent
(5%).

With respect to any ICAP II Group Contracts, the following commission
chargebacks will apply:

         (1)      Upon termination of the Contract, all commissions paid on
                  premiums received in the 12 months prior to termination of the
                  Contract will be deemed unearned and shall be returned to the
                  Insurer upon demand or, in the absence of such demand, charged
                  back to the recipient of the commission; and

         (2)      If, within the first four years of the Contract, any
                  participant under the Contract retires or terminates
                  employment resulting in a withdrawal of the participant's
                  funds from the Contract, all commissions paid on behalf of
                  such participant's contributions will be deemed unearned and
                  shall be returned to the Insurer upon demand or, in the
                  absence of such demand, charged back to the recipient of the
                  commission; if no premium information is available with
                  respect to that participant, the charge back will be
                  calculated based upon the amount of the withdrawal of funds.

SUSPENSION OF PAYMENTS
We may suspend or postpone any payments from the Variable Accounts if any of the
following occur:

(a)      The New York Stock Exchange is closed.
(b)      Trading on the New York Stock Exchange is restricted.
(c)      An emergency exists such that it is not reasonably practical to
         dispose of securities in the Separate Account or to determine the
         value of its assets, or
(d)      The Securities and Exchange Commission, by order, so permits for the
         protection of security holders.

Conditions in (b) and (c) will be decided by or in accordance with rules of the
Securities and Exchange Commission.

PURCHASE PAYMENTS
Purchase Payments are flexible. This means that You, subject to Company declared
minimums and maximums, may change the amounts, frequency or timing of Purchase
Payments. Purchase Payments may be allocated among one or more of the Fixed
Account Options and one or more Variable Accounts of the Separate Account in
accordance with instructions from You. We reserve the right to specify the
minimum that may be allocated to a Variable Account under the Certificate.

SUBSTITUTION OF FUND
If the shares of any of the Funds or any Series of the Fund should no longer be
available for investment by the Separate Account or if, in the judgment of the
Company's Board of Directors, further investment in the shares of a Fund is no
longer appropriate in view of the purpose of the Contract, the Company may
substitute shares of another mutual fund for Fund shares already purchased or to
be purchased in the future by Purchase Payments under the Contract. No
substitution of securities may take place without prior approval of the
Securities and Exchange Commission and under such requirements as it may impose.

SEPARATE ACCOUNT
The Separate Account is a separate investment account of the Company. It is
shown on the Contract Data Page. The assets of the Separate Account are the
property of the Company. However, they are not chargeable with the liabilities
arising out of any other business the Company may conduct. Each Variable Account
is not chargeable with liabilities arising out of any other Variable Account.

<PAGE>   9
                             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 Variable Accounts for the
Participant.

NUMBER OF ACCUMULATION UNITS
For each Variable Account, the number of Accumulation Units is the sum of:

Each Purchase Payment and transfer allocated to the Variable Account, reduced by
applicable premium taxes, if any:

Divided by

The Accumulation Unit Value for that Variable Account as of the Valuation Period
in which the Purchase Payment or transfer amount is received.

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

ACCUMULATION UNIT VALUE (AUV)
The AUV of a Variable Account for any Valuation Period is calculated by
subtracting (2) from (1) and dividing the result by (3) where:

         (1)      is the total value at the end of the given Valuation Period of
                  the assets attributable to the Accumulation Units of the
                  Variable Account minus the total liabilities;
         (2)      is the cumulative unpaid charge for assumption of mortality,
                  expense distribution expense and guaranteed death benefit
                  expense risks (See CHARGES AND DEDUCTIONS);
         (3)      is the number of Accumulation Units outstanding at the end of
                  the given Valuation Period.

FIXED ACCOUNT ACCUMULATION VALUE
The Fixed Account Accumulation Value under a Certificate shall be the sum of all
monies allocated or transferred to the Fixed Account, reduced by any applicable
premium taxes, plus all interest credited on the Fixed Account during the period
that the Certificate has been in effect. This amount shall be adjusted for
withdrawals, annuitizations, transfers, and charges.

FIXED ACCOUNT GUARANTEE PERIOD OPTIONS
For any amounts allocated to the Fixed Account, the Participant will select the
duration of the Guarantee Period(s) from those listed on the Certificate Data
Page. Such amounts will earn interest at the Current Interest Rate for the
chosen duration, compounded annually during the entire Guarantee Period. In no
event will the Current Interest Rate be less than the Subsequent Guarantee Rate
specified on the Certificate Data Page.

You may allocate Purchase Payments, or make transfers from the Variable Account
Options, to the Fixed Account at any time prior to the latest Annuity Date.
However, no Guarantee Period other than one year may be chosen which extends
beyond the latest Annuity Date. For thirty (30) days following the date of
expiration of the current Guarantee Period, You may renew for the same or any
other Guarantee Period at the then Current Interest Rate or may transfer all or
a portion of the amount to the Variable Accounts. Transfers from the Fixed
Account may take place thirty (30) days following the end of a Guarantee Period
without being subject to Market Value Adjustment (MVA). If the Participant does
not specify a Guarantee Period at the time of renewal, We will select the same
Guarantee Period as has just expired, so long as such Guarantee Period does not
extend beyond the latest Annuity Date. If such Guarantee Period does extend
beyond the latest Annuity Date, We will choose the longest period that will not
extend beyond such date. If a renewal occurs within one year of the latest
Annuity Date We will credit interest up to the latest Annuity Date at the then
Current Interest Rate for the one year Guarantee Period.

<PAGE>   10
MARKET VALUE ADJUSTMENT
Except on the latest Annuity Date of the chosen Guarantee Period, any amount
withdrawn, transferred or annuitized prior to the end of that Guarantee Period
may be subject to a MVA. The MVA will be calculated by multiplying the amount
withdrawn, transferred or annuitized by the formula described below:


                    {(1+I)/(1+J+0.005)} to the n/12-1 power


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

J= The Current 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 current rates 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.

There will be no Market Value Adjustment on withdrawals from the Fixed Account
in the following situations: (1) Death Benefit paid upon death of the
Participant; (2) amounts withdrawn to pay fees or charges; and (3) amounts
withdrawn from the Fixed Account within thirty (30) days after the end of the
Guarantee Period.


<PAGE>   11
                             CHARGES AND DEDUCTIONS

We will deduct the following charges from the Certificate:

CONTRACT 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 Contract Value is withdrawn in full if withdrawal is
not on a 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.

CONTINGENT DEFERRED SALES CHARGE
This charge may be deducted upon withdrawal of the Contract Value, in whole
or in part.  See WITHDRAWAL PROVISIONS.

EXPENSE RISK CHARGE
On an annual basis this charge equals 0.35% of the average daily total net asset
value of the Variable Accounts. 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 Variable Account. This charge is to compensate Us for all
distribution expenses associated with the Certificate.

MORTALITY RISK CHARGE
On an annual basis this charge equals 0.9% of the average daily total net asset
value of the Variable Account. This charge is to compensate Us for assuming the
mortality risks under 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 Variable Account. This charge is to compensate Us for the risk
assumed as a result of contractual obligations to provide an enhanced minimum
guaranteed Death Benefit prior to the Annuity Date.

MARKET VALUE ADJUSTMENT
See MARKET VALUE ADJUSTMENT section.

<PAGE>   12
                               TRANSFER PROVISION

Prior to the Annuity Date, You may transfer all or part of Your Contract Value
to any of the Variable Accounts or the Fixed Account, 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.

Transfers will be effected at the end of the Valuation Period in which We
receive Your request for the transfer.

TRANSFERS OF ACCUMULATION UNITS BETWEEN VARIABLE ACCOUNTS 
Both prior to and after the Annuity Date, You may transfer all or a portion of
Your investment in one Variable Account to another Variable Account. A transfer
will result in the purchase of Accumulation Units in a Variable Account and the
redemption of Accumulation Units in the other Variable Account.

The minimum amount which can be transferred between Variable Accounts and the
amount that can remain in the Variable Account is subject to Company limits.

TRANSFERS OF ACCUMULATION UNITS TO AND FROM THE FIXED ACCOUNT 
Both prior to and after the Annuity Date, You may transfer all or any part of
the Contract Value from the Variable Account(s) to the Fixed Account of the
Certificate. After the Annuity Date no transfers from the Fixed Account to the
Variable Account are allowed. For transfers from the Fixed Account prior to the
Annuity Date see ACCUMULATION PROVISIONS - FIXED ACCOUNT ACCUMULATION VALUE.

The amount transferred to the Fixed Account from a Variable Account will be
equal to the annuity reserve for the Payee's interest in that Variable Account.
The annuity reserve is the product of (a) multiplied by (b) multiplied by (c),
where

         (a)      is the number of Annuity Units representing the
                  Participant's interest in the Variable Account;
         (b)      is the Annuity Unit Value for the Variable Account; and
         (c)      is the present value of $1.00 per payment period as of the
                  age of the Annuitant at the time of transfer for the Annuity
                  Option, determined using the 1983a Annuity Mortality Tables
                  with interest at 3.5% per year.

Amounts transferred to the Fixed Account will be applied under the Annuity
Option at the age of the Annuitant at the time of the transfer. All amounts and
Annuity Unit Values will be determined as of the end of the Valuation Period
preceding the effective date of the transfer.


<PAGE>   13
                              WITHDRAWAL PROVISION

Prior to the Annuity Date while the Annuitant is living, You may withdraw all or
part of the Contract Value amounts under this Certificate by informing Us at Our
Annuity Service Center. For full withdrawal, this Certificate must be returned
to Our Annuity Service Center.

Absent written notification to the contrary, withdrawals and any applicable
charge will be deducted from the Contract Value in proportion to its allocation
among the Fixed Account and the Variable Accounts. Withdrawals will be based on
values at the end of the Valuation Period in which the request for withdrawal
and the Certificate (in the case of a full withdrawal), are received at the
Annuity Service Center. Unless the SUSPENSION OF PAYMENTS or DEFERMENT OF
PAYMENTS sections are in effect, payment of withdrawals will be made within
seven days. Market Value Adjustment may be applied to withdrawals.

CONTINGENT DEFERRED SALES CHARGE
Withdrawal of all or part of the Contract Value may be subject to a Contingent
Deferred Sales Charge (CDSC). However, no CDSC is made on an amount withdrawn
which is considered to be a withdrawal of earnings.

In addition, for the first withdrawal of a Contract Year, no Contingent Deferred
Sales Charge is applied to such part of the withdrawal which does not exceed the
larger of (a) earnings in the Certificate or (b) the Free Corridor. The Free
Corridor is equal to 10% of the sum of Purchase Payments made more than one year
prior to the date of withdrawal, are still subject to CDSC, and are not yet
withdrawn. The portion of a free withdrawal, which exceeds the sum of earnings
attributable to the Participant and premiums which are both no longer subject to
CDSC and not yet withdrawn, is assumed to be a withdrawal against future
earnings. We reserve the right to allow the Free Corridor to include all
Purchase Payments still subject to CDSC which are not yet withdrawn. If this is
done, it will apply to all Participants and Participants will be notified of
such change.

For the purpose of determining the CDSC, a withdrawal will be attributed to
amounts in the following order: (1) earnings in the Certificate, (2) Purchase
Payments which are both no longer subject to CDSC and are not yet withdrawn, and
(3) Purchase Payments subject to CDSC. Purchase Payments, when withdrawn, are
assumed to be withdrawn on a first-in first-out (FIFO) basis. The charge applied
to any withdrawal subject to CDSC will depend on the age of the Purchase
Payments to which the withdrawal is attributed.

</TABLE>

The CDSC will be assessed against the Variable Accounts and the Fixed Account in
the same proportion as the remaining Contract Value is allocated unless the
allocation is specified by the Participant. If the remaining Contract Value is
insufficient to cover the Contingent Deferred Sales Charge, any remaining
balance will be deducted from the dollar amount requested.

In addition to a CDSC, a withdrawal from the Fixed Account may also incur a
Market Value Adjustment. See ACCUMULATION PROVISIONS - MARKET VALUE ADJUSTMENT
for further details.

                             DEATH BENEFIT PROVISION

We will pay a Death Benefit to the Beneficiary upon Our receiving due proof that
the Participant died prior to the Annuity Date. The Beneficiary may elect to
receive a single sum distribution or to receive annuity payments. If a single
sum payment is requested, payment will be in accordance with any applicable laws
and regulations governing payments on death. If an Annuity Option is desired, an
Option must be elected within 60 days of Our receipt of due proof of the
Participant's death at our Annuity Service Center; otherwise a single sum
payment will be made at the end of such 60 day period. Funds will remain
allocated pursuant to the last allocation and instructions in effect at the
Participant's death until Our Annuity Service Center receives new written
instructions.

PROOF OF DEATH 

Due Proof of Death means:

1.       a copy of a certified death certificate; OR
2.       a copy of a certified 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 is equal to the greater of:

1.       the Contract Value at the end of the Valuation Period during which We
         receive at Our Annuity Service Center due proof of the Participant's
         death and an election of the type of payment to be made; OR
2.       the total amount of Purchase Payments compounded at 4% interest, minus
         the sum of 
         (a)      the total amount of partial withdrawals and partial
                  annuitizations compounded at 4% interest, and
         (b)      premium taxes incurred, compounded at 4%; OR
3.       After the seventh Contract Year, the Contract Value at the seventh
         Certificate Anniversary compounded at 4% interest, plus (a) any
         Purchase Payments since the seventh anniversary,
                  compounded at 4% minus the sum of
         (b)      the total amount of partial withdrawals and partial
                  annuitizations since the seventh anniversary, compounded at
                  4%, and
         (c)      premium taxes incurred since the seventh anniversary,
                  compounded at 4%.

If the Participant was age 70 or older on the date of issue, 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 date of issue, both (2) and (3) above will be
compounded at 3% rather than 4%.

BENEFICIARY
The Beneficiary is as stated in the Participant Enrollment Form unless later
changed by the Participant. If two or more persons are named, those surviving
the Participant will share equally unless otherwise stated. If the Annuitant
survives the Participant, and there are no surviving Beneficiaries, the
Annuitant will be deemed the 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.

While the Participant is living and 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 receive the notice.

<PAGE>   15
DEATH OF PARTICIPANT
If the Participant dies before the Annuity Date, the Beneficiary will have
the following options;

1.       Collect the Death Benefit in a lump sum payment; OR 
2.       Collect the Death Benefit in the form of one of the Annuity Options.
         The payments must be over the life of the Beneficiary or over a period
         not extending beyond the life expectancy of the Beneficiary. This
         option must be selected and payments commence within one year after
         Participant's death, OR
3.       Receive the entire Contract Value adjusted for Contingent Deferred
         Sales Charge and Market Value Adjustment, if applicable, within 5 years
         of the date of death of the Participant, OR
4.       If the Beneficiary is the Participant's spouse, the Beneficiary may
         continue the Contract in force.

If there is no surviving Beneficiary, the Death Benefit will be paid in a lump
sum to the Participant's estate. If there is more than one surviving
Beneficiary, the Beneficiaries must choose to receive their respective portions
of the Death Benefit according to either (1), (2) or (3) above.

<PAGE>   16
                               ANNUITY PROVISIONS


PAYMENTS TO PARTICIPANT
Unless otherwise requested by the Participant, the Company will make annuity
payments to the Participant. If the Participant wants the annuity payments to be
made to some other Payee, We will make such payments subject to the following:

(a)      A written request must be filed at the Annuity Service Center.
(b)      Such request must be filed not 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
To the extent a fixed Annuity Option has been elected, the proceeds payable
under this Certificate less any applicable premium taxes, shall be applied to
the payment of the Annuity Option elected at whichever of the following is more
favorable to the Payee: (a) the annuity rates based upon the applicable tables
in the Certificate; or (b) the then current rates provided by the Company on
Contracts of this type on the Annuity Date. 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 Contract Value allocated to Fixed Annuity Payments less any
applicable premium taxes, charges and the MVA to the annuity table applicable to
the Annuity Option chosen.

AMOUNT OF VARIABLE ANNUITY PAYMENTS

(a)      FIRST VARIABLE PAYMENT: The dollar amount of the first monthly
         annuity payment will be determined by applying the portion of the
         Contract Value allocated to Variable Annuity Payments, less any
         applicable Premium Taxes, to the annuity table applicable to the
         Annuity Option chosen.  If more than one Variable Account has been
         selected, the value of the Participant's interest in each Variable
         Account is applied separately to the annuity table to determine the
         amount of the first annuity payment attributable to the Variable
         Account.

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

(c)      VALUE OF EACH VARIABLE ANNUITY UNIT:  The initial value of an
         Annuity Unit of each Variable Account was arbitrarily set at $10
         when the Variable Accounts were established.  The value may increase
         or decrease from one Valuation Period to the next.  For any
         Valuation Period, the value of an Annuity Unit of a particular
         Variable Account is the value of that Annuity Unit during the last
         Valuation Period, multiplied by the Net Investment Factor for that
         Variable Account for the current Valuation Period.

The Net Investment Factor for any Variable Account for any Valuation Period is
determined by dividing (a) by (b) and then subtracting (c) from the result
where:

         (a)      is the net result of:

                  (1)      the net asset value of a Series of the Fund share
                           held in the Variable Account determined as of the end
                           of the Valuation Period, plus
                  (2)      the per share amount of any dividend or other
                           distribution declared by the Series of the Fund on


<PAGE>   17
                           the shares held in the Variable Account if the
                           "ex-dividend" date occurs during the Valuation
                           Period, plus or minus
                  (3)      a per share credit or charge with respect to any
                           taxes paid or reserved for by the Company during the
                           Valuation Period which are determined by the Company
                           to be attributable to the operation of the Variable
                           Account (no federal income taxes are applicable under
                           present law)

         (b)      is the net asset value of a Series of the Fund share held in
                  the Variable Account determined as of the end of the preceding
                  Valuation Period; and

         (c)      is the asset charge factor determined by the Company for the
                  Valuation Period to reflect the Expense Risk Charge,
                  Distribution Expense Charge, Mortality Risk Charge, and
                  Guaranteed Death Benefit Risk Charge.

         The result is then multiplied by a factor that neutralizes the Assumed
Investment Rate.

         (d)      SUBSEQUENT VARIABLE ANNUITY PAYMENTS: After the first Variable
                  Annuity payment, payments will vary in amount according to the
                  investment performance of the applicable Variable Accounts.
                  The amount may change from month to month. The amount of each
                  subsequent payment is the sum of:

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

Multiplied by

The value of an Annuity Unit for that Variable Account at the end of the
Valuation Period immediately preceding in which payment is due.

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

                                 ANNUITY OPTIONS

Upon written election filed with the Company at its Annuity Service Center, all
or part of the Contract Value may be applied to provide one of the following
options or any Annuity Option that is mutually agreeable. The portion of the
Contract Value which is in the Fixed Account immediately prior to the Annuity
Date, applied to an annuity may be subject to a Market Value Adjustment. See
ACCUMULATION PROVISIONS - MARKET VALUE ADJUSTMENT for further details.

OPTION 1 - LIFE ANNUITY, LIFETIME MONTHLY PAYMENTS GUARANTEED 
Monthly payments payable to the Payee during the lifetime of the Annuitant. No 
further payments are payable after the death of the Annuitant and there is no 
provision for a Death Benefit payable to the Beneficiary.

OPTION 2 - JOINT AND SURVIVOR LIFE ANNUITY
Monthly payments payable to the Payee during the joint lifetime of the Annuitant
and a designated second person and during the lifetime of the survivor.

If a reduced payment to the survivor is desired, Variable Annuity payments, will
be determined using either one-half or two-thirds of the number of each type of
Annuity Unit credited to the Certificate. Fixed monthly payments, will be equal
to either one-half or two-thirds of the fixed monthly payment payable during the
joint lifetime of the Annuitant and the designated second person.

OPTION 3 - JOINT AND SURVIVOR LIFE ANNUITY - 120 MONTHLY PAYMENTS GUARANTEED
Monthly payments payable to the Payee during the joint lifetime of the Annuitant
and designated second person and continuing during the remaining lifetime of the
survivor, with the guarantee that if, at the death of the survivor, payments
have been made for less than 120 monthly periods, any remaining guaranteed
annuity payments will be continued to the Beneficiary named on the Annuity
Option Selection Form. In the event of death of the Annuitant and the designated
second person under this option, the Certificate provides that in certain
circumstances, the discounted value of the remaining guaranteed annuity
payments, if any, will be calculated and paid in one sum.

OPTION 4 - LIFE ANNUITY WITH 120 OR 240 MONTHLY PAYMENTS GUARANTEED 
An annuity payable monthly to the Payee during the lifetime of the Annuitant
with the guarantee that if, at the death of the Annuitant, payments have been
made for less than the 120 or 240 monthly periods, as selected, payments will be
made in the same manner as provided under OPTION 3 above. In the event of death
of the Annuitant under this option, the Certificate provides that in certain
circumstances, the discounted value of the remaining payments, if any, will be
calculated and paid in one sum.

OPTION 5 - FIXED PAYMENTS FOR A SPECIFIED PERIOD CERTAIN 
Fixed monthly payments payable to the Payee for any specified period of time
(three (3) years or more, but not exceeding thirty (30) years), as elected. The
election must be made for full twelve month periods. In the event of death of
the Payee under this option, the Certificate provides that in certain
circumstances, the discounted value of the remaining payments, if any, will be
calculated and paid in one sum.

                 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.

                     ANCHOR NATIONAL LIFE INSURANCE COMPANY


         We, the undersigned, acting as incorporators for the purpose of
redomesticating Anchor National Life Insurance Company, a California

Revised Statutes Section 20-231.A, do hereby adopt the following Amended and
Restated Articles of Incorporation and Articles of Redomestication for said
corporation.

         The corporation was incorporated in the State of California on April
12, 1965.


                                   ARTICLE III

         The existence of the corporation shall be perpetual.


                                   ARTICLE IV

         Upon the approval of these Amended and Restated Articles of
Incorporation and Articles of Redomestication by the necessary regulatory
authorities, Anchor National Life Insurance Company shall be and continue to be
possessed of all privileges, franchises and powers to the same extent as if it
had been originally incorporated under the laws of the State of Arizona; and all
privileges, franchises and powers belonging to said corporation, and all
property, real, personal and mixed, and all debts due on whatever account, all
Certificates of Authority, agent appointments, and all chooses in action, shall
be and the same are hereby ratified, approved, confirmed and assured to Anchor
National Life Insurance Company with like effect and to all intents and purposes
as if it had been originally incorporated under the laws of the State of
Arizona. Said corporation shall be given recognition as a domestic corporation
of the State of Arizona from and after April 12, 1965, and as a domestic insurer
of the State of Arizona from and after December 2, 1966, the dates of its
initial incorporation and authorization to transact insurance business under the
laws of the State of California, effective the latter of January 1, 1996 or the
date of filing with the Arizona Corporation Commission.


                                    ARTICLE V

         The nature of the business to be transacted and the objects and
purposes for which this corporation is organized include the transaction of any
and all lawful business for which insurance corporations may be incorporated
under the laws of the State of Arizona without limitation, and as said laws may
be amended from time to time, and specifically said corporation shall be
authorized to transact life insurance, disability insurance and annuities, as
defined under Arizona Revised Statutes, Section 20-254, 20-253 and 20-254.01
respectively, together with such other kinds of insurance as the corporation may
from time to time be authorized to transact, and to act as a reinsurer of
business for which it is duly authorized. Consistent with the applicable federal
and state requirements, the Company may issue funding agreements and guaranteed
investment contracts as defined under Arizona Revised Statutes, Section 20-208.


                                   ARTICLE VI

<PAGE>   2
preferential right to subscription to any shares or securities convertible into
shares of stock of the corporation, nor any right of subscription to any thereof
other than such, if any, as the Board of Directors in its discretion may
determine, and at such price as the Board of Directors in its discretion may
fix; and any shares or convertible securities which the Board of Directors may
determine to offer for subscription to the holders of stock at the time
existing.

         Nothing herein contained shall be construed as prohibiting the
corporation from issuing any shares of authorized but unissued common stock for
such consideration as the Board of Directors may determine, provided such
issuance is approved by the shareholders of the corporation by a majority of the
votes entitled to be cast at any annual or special meeting of shareholders
called for that purpose. No such authorized but unissued stock may, however, be
issued to the shareholders of the corporation by way of a stock dividend,
split-up or in any other manner of distribution unless the same ratable stock
dividend, stock split-up or other distribution be declared or made in voting
common stock to the holder of such voting common stock at the time outstanding.
Each holder of common stock shall be entitled to participate share for share in
any cash dividends which may be declared from time to time on the common stock
of the corporation by the Board of Directors and to receive pro rata the net
assets of the corporation on liquidation.

Directors consisting of not less than five (5) nor more than fifteen (15)

corporation. Ten (10) directors shall constitute the initial Board of Directors.
The names and addresses of the persons who are to serve as directors until the
next annual meeting of shareholders or until their successors are elected and
qualified, and of the persons who are to serve as officers until the next annual
meeting of the directors or until their successors are elected and qualify, are:

counsel of its own choosing, to defend him in the action, or shall have
unreasonable refused to cooperate in the defense of such action.


                                   ARTICLE IX

                  Section 1. Annual Meetings. The annual meeting of the
shareholders of the Corporation shall be held on the fourth Thursday in April of
each year or such other dates and times as may be determined. Not less than ten
(10) nor more than fifty (50) days' written or printed notice stating the place,
day and hour of each annual meeting shall be given in the manner provided in
Section 1 of Article IX hereof. The business to be transacted at the annual
meeting shall include the election of directors, consideration and action upon
the reports of officers and directors and any other business within the power of
the Corporation. All annual meetings shall be general meetings.

                  Section 2. Special Meetings Called by President or Board of
Directors. At any time in the interval between annual meetings, special meetings
of shareholders may be called by the President, the Secretary or by two (2) or
more directors, upon ten (10) days' written or printed notice, stating the
place, day and hour of such meeting and the business proposed to be transacted
thereat. Such notice shall be given in the manner provided in Section 1 of
Article IX. No business shall be transacted at any special meeting except that
named in the notice.

                  Section 3. Special Meeting Called by Shareholders. Upon the
request in writing delivered to the President or Secretary of the Corporation by
the holders of ten percent (10%) or more of all shares outstanding and entitled
to vote, it shall be the duty of the President or Secretary of the Corporation
to call forthwith a special meeting of the shareholders. Such request shall
state the purpose or purposes of such meeting and the matters proposed to be
acted on thereat. The Secretary of the Corporation shall inform such
shareholders of the reasonably estimated cost of preparing and mailing the
notice of the meeting. If upon payment of such costs to the corporation, the
person to whom such request in writing shall have been delivered shall fail to
issue a call for such meeting within ten (10) days after the receipt of such
request and payment of costs, then the shareholders owning ten percent (10%) or
more of the voting shares may do so upon giving fifteen (15) days' notice of the
time, place and object of the meeting in the manner provided in Section 1 of
Article IX.

                  Section 4. Removal of Directors. At any special meeting of the
shareholders called in the manner provided for by this Article, the
shareholders, by a vote of a majority of all shares of stock outstanding and
entitled to vote, may remove any director or the entire Board of Directors from
office and may elect a successor or successors to fill any resulting vacancies
for the remainder of his or their terms.

                  Section 5. Voting; Proxies; Record Date. At all meetings of
shareholders any shareholder entitled to vote may vote by proxy. Such proxy
shall be in writing and signed by the shareholder or by his duly authorized
attorney in fact. It shall be dated, but need not be sealed, witnessed or
acknowledged. The Board of Directors may fix the record date for the
determination of shareholders entitled to vote in the manner provided in Section
4 of Article IX hereof.

                  Section 6. Quorum. The presence in person or by proxy of the
persons entitled to vote a majority of the voting shares of any meeting shall
constitute a quorum for the transaction of business. If at any annual or special
meeting of shareholders a quorum shall fail to attend in person or by proxy, a
majority in interest attending in person or by proxy may adjourn the meeting
from time to time, not exceeding thirty (30) days in all, and thereupon any
business may be transacted which might have been transacted at the meeting
originally called had the same been held at the time so called.

                  Section 7.  Filing Proxies.  At all meetings of shareholders, 
the proxies shall be filed with and be verified by the Secretary


<PAGE>   2
of the Corporation or, if the meeting shall so decide, by the Secretary of the
meeting.

                  Section 8. Place of Meetings. All meetings of shareholders
shall be held at such place, either within or without the State of Arizona, on
such date and at such time as may be determined from time to time by the Board
of Directors (or the Chairman in the absence of a designation by the Board of
Directors).

                  Section 9. Order of Business.  The order of business at all 
meetings of shareholders shall be as determined by the Chairman of the meeting.

                  Section 10. Action Without Meeting. Directors may be elected
without a shareholders' meeting by a consent in writing, setting forth the
action so taken, signed by all persons entitled to vote for the election of
directors; provided, however, that the foregoing shall not limit the power of
directors to fill vacancies in the Board of Directors, and that a director may
be elected to fill a vacancy not filled by the directors by written consent in
the manner provided by the General Corporation Law.

                  Any other action, which under any provision of the General
Corporation Law, may be taken at a meeting of the shareholders, may be taken
without a meeting, and without notice except as hereinafter set forth, if a
consent in writing, setting forth the action so taken, is signed by the holders
of outstanding shares having not less than the minimum number of votes that
would be necessary to authorize or take such action at a meeting at which all
shares entitled to vote thereon were present and voted.

                  All written consents shall be filed with the Secretary of the
Corporation. Any shareholder giving a written consent, or the shareholder's
proxyholders, or a transferee of the shares of a personal representative of the
shareholder or their respective proxyholders, may revoke the consent by a
writing receiving by the Corporation prior to the time that written consents of
the number of shares required to authorize the proposed action have been filed
with the Secretary of the Corporation, but may not do so thereafter. Such
revocation is effective upon its receipt by the Secretary of the Corporation.

                  Section 1. Powers. The Board of Directors shall have the
control and management of the affairs, business and properties of the
Corporation. They shall have and exercise in the name of the Corporation and on
behalf of the Corporation all the rights and privileges legally exercisable by
the Corporation, except as otherwise provided by law, by the Charter or by these
Bylaws. A director need not be a shareholder or a resident of Arizona.

                  Section 2. Number; Term of Office; Removal. The number of
directors of the Corporation shall be not less than five (5) nor more than
fifteen (15). The number to be elected at each annual meeting shall be fixed by
resolution of the directors and stated in the notice of the meeting, subject,
however, to approval by the shareholders voting at the meeting. The directors
shall hold office for the term of one year, or until their successors are
elected and qualify. A director may be removed from office as provided in
Section 4 of Article I hereof.

                  Section 3. Vacancies. If the office of a director becomes
vacant, or if the number of directors is increased, such vacancy may be filled
by the Board by a vote of a majority of directors then in office though not less
than a quorum. The shareholders may, however, at any time during the term of
such director, elect some other person to fill said vacancy and thereupon the
election by the Board shall be superseded and such election by the shareholders
shall be deemed a filling of the vacancy and not a removal and may be made at
any special meeting called for that purpose.

                  Section 4. Organization Meetings; Regular Meetings. The Board
of Directors shall meet for the election of officers and any other business as
soon as practicable after the adjournment of the annual meeting of the
shareholders. No notice of the organization meeting shall be required if it is
held at the same place and immediately following the annual meeting of the
shareholders. Other regular meetings of the Board of Directors may be held at
such intervals as the Board may from time to time prescribe.

                  Any action required or permitted to be taken at a meeting of
the Board of Directors or of a committee of the Board may be taken without a
meeting, if a unanimous written consent which sets forth the action is signed by
each member of the Board or committee and filed with the minutes of proceedings
of the Board or committee.

                  Unless otherwise restricted by the Articles of Incorporation
or these Bylaws, members of the Board of Directors, or any committee designated
by the Board of Directors, may participate in a meeting of the Board of
Directors, or such committee, as the case may be, by means of telephone
conference or similar communications equipment by means of which are persons
participating in the meeting can hear each other, and such participation in a
meeting shall constitute presence in person at the meeting.

                  Section 5. Special Meetings.  Special meetings of the Board 
may be called by the President or by a majority of the directors. At least
twenty-four (24) hours' notice shall be given of all special meetings; with the
consent of the majority of the directors, a shorter notice may be given.

                  Section 6. Quorum. A majority of the Board of Directors shall
constitute a quorum for the transaction of business, but such number may be
decreased and/or increased at any time or from time to time by vote of a
majority of the entire Board to any number not less than two (2) directors or
not less than one-third of the directors, whichever is greater.

                  Section 7. Place of Meetings. The Board of Directors shall
hold its meetings at such place, either within or without the State of Arizona,
and at such time as may be determined from time to time by the Board of
Directors (or the Chairman in the absence of a determination by the Board of
Directors).

                  Section 8. Rules and Regulations. The Board of Directors may
adopt such rules and regulations for the conduct of its meetings and the
management of the affairs of the Corporation as the Board may deem proper and
not inconsistent with the laws of the State of Arizona or these Bylaws or the
Charter.

                  Section 9. Compensation.  The directors, as such, may


<PAGE>   4
receive a stated salary for their services and/or a fixed sum and expenses of
attendance may be allowed for attendance at each regular or special meeting of
the Board of Directors. Such stated salary and/or attendance fee shall be
determined by resolution of the Board unless the shareholders have adopted a
resolution relating thereto, provided that nothing herein contained shall be
construed to preclude a director from serving in any other capacity and
receiving compensation therefor.

                  Section 10. Chairman of the Board. The Board of Directors
shall provide for a Chairman of the Board from among its members. So long as
there shall be a person so active, he shall preside at all meetings of the Board
and at all joint meetings of officers and directors. In the absence of the
Chairman, the Vice Chairman, if any, or in his absence, the President, shall
preside at all meetings of the Board and all joint meetings of officers and
directors.

                  Section 11. Investment Committee. There shall be an Investment
Committee consisting of the President of the Corporation ex officio and such
members of the Board of Directors and/or officers and employees as the Board may
by resolution prescribe. No investments or loans (other than policy loans or
annuity contract loans) shall be made unless the same be authorized or approved
by the Board of Directors or the Investment Committee. The Investment Committee
shall maintain minutes of its meetings and shall submit regular reports to the
Board of Directors.

                  Section 12. Executive Committee. The Board of Directors may
appoint from among its members an Executive Committee composed of three (3) or
more directors, and may delegate to such Committee, in the interval between the
meetings of the Board of Directors, any and all of the powers of the Board of
Directors in the management of the business and affairs of the Corporation,
except the power to declare dividends, issue stock, select directors to fill
vacancies in the membership of the Executive Committee or recommend to
shareholders any action requiring shareholders' approval. The members of such
Committee shall constitute a quorum for the transaction of business at any
meeting and the act of a majority of the members present at any meeting at which
the quorum requirement is satisfied shall be the act of the Board of Directors.
In the absence of any member of the Executive Committee necessary to constitute
a quorum, the members thereof present at any meeting, whether or not they
constitute a quorum, may, with telephonic approval of one of the absent members
of the Executive Committee, appoint a member of the Board of Directors to act in
place of such absent member.

                  Section 13. Other Committees. The Board of Directors may
appoint from its own members and, where permitted by law, from the Corporation's
officers and/or employees, such standing, temporary, special or ad hoc
committees as the Board may determine, investing such committees with such
powers, duties and functions as the Board may prescribe. All such committees
shall include the President, ex officio.

                  Section 14. Advisory Board. The Board of Directors may elect
an Advisory Board to serve until the next annual meeting of the Board of
Directors or until their successors are elected and qualify. Such Board shall
consist of a number as determined from time to time by the Board of Directors,
and they shall be advised of the meetings of the Board of Directors and
authorized to attend the meetings and counsel with them, but shall have no vote.
The Board of Directors (and between meeting of the Board of Directors, the
Executive Committee) shall have the authority to increase or decrease the number
of members to the Advisory Board and to elect one or more members to the
Advisory Board to serve until the next meeting of the Board of Directors and
until their successors are elected and qualify, and may provide for the
compensation and other rules and regulations with respect to such Board.

                  Section 15. Procedures; Meetings. The Committees shall keep
minutes of their proceedings and shall report the same to the Board of Directors
at the meeting next succeeding, and any action by the Committees shall be
subject to revision and alteration by the Board of Directors, provided that no
rights of third persons shall be affected by any such revision or alteration.

time to time deem appropriate, and except those persons holding contracts for
fixed terms, those officers appointed by the President shall hold office only
during his pleasure or until their successors are appointed and qualify. Any two

may be held by the same persons, but no officer shall execute, acknowledge or
verify any instrument in more than one capacity when such instrument is required
to be executed, acknowledged, or verified by any two (2) or more officers. The
Board of Directors or the President may from time to time appoint other agents
and employees, with such powers and duties as they may deem proper.

the Board of Directors, shall perform all the duties of the President, and when
so acting shall have all the powers of, and be subject to all the restrictions
upon, the President. The Vice Presidents shall have such other powers and
perform such other duties as from time to time may be prescribed for them
respectively by the Board of Directors or the Bylaws.

                  Section 4. Treasurer. Unless there shall be a financial Vice
President designated by the Board of Directors as the chief financial officer of
the Corporation, having general supervision over its finances, the Treasurer
shall be the chief financial officer with such authority. He shall also have

duties as may be assigned to him by the Board of Directors.

                  Section 5. Secretary of the Corporation. The Secretary of the

to time in the absence of any one of said officers or, at any other time,
designate any other person or persons on behalf of the Corporation, to sign any
contracts, deeds, notes, or other instruments in the place or stead of any of
said officers, and designate any person to fill any one of said offices,
temporarily or for any particular purpose; and any instruments so signed in
accordance with a resolution of the Board shall be the valid act of this
Corporation as fully as if executed by any regular officer.


                                   ARTICLE IV.

                                  Resignation.

                  Any director or officer may resign his office at any time.


<PAGE>   6
Such resignation shall be made in writing and shall take effect from the time of
its receipt by the Corporation, unless some time be fixed in the resignation,
and then from that date. The acceptance of a resignation shall not be required
to make it effective.


                                   ARTICLE V.

                   Indemnification of Directors and Officers.

                  The Corporation shall indemnify any and all of its existing
and former directors and officers and their spouses against all expenses
incurred by them and each of them, including but not confined to legal fees,
judgments and penalties which may be incurred, rendered or levied in any legal
or administrative action brought against any of then, for or on account of any
action or omission alleged to have been committed while acting within the scope
of employment as director of officer of the Corporation to the fullest extent
allowable pursuant to the Arizona General Corporation Law as may be amended from
time to time. Whenever any such person has grounds to believe that he may incur
any such aforementioned expense, he shall promptly make a full report of the
matter to the President and the Secretary of the Corporation. Thereafter, the
Board of Directors of the Corporation shall, within a reasonable time, determine
if such person acted, or failed to act, in good faith and in a manner he
reasonably believed to be in or not opposed to the best interest of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. If the Board of Directors
determines that such person acted, or failed to act, in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful, then indemnification shall
be mandatory and shall be automatically extended as specified herein, provided,
however, that the Corporation shall have the right to refuse indemnification,
wholly or partially, in any instance in which the person to whom indemnification
would otherwise have been applicable shall have unreasonably refused to permit
the Corporation, at its own expense and through counsel of its own choosing, to
defend him in the action, or shall have unreasonably refused to cooperate in the
defense of such action.


                                   ARTICLE VI.

                                  Fiscal Year.

of the Corporation and sealed with the seal or facsimile seal of the
Corporation. Any stock certificates bearing the facsimile signatures of the
officers above named shall be manually signed by an authorized representative of
the Corporation's duly constituted transfer agent. If an officer whose signature
appears on a certificate ceases to be an officer before the certificate is
issued, it may, nevertheless, be issued with the same effect as if such officer
were still in office.

                  Section 2. Transfers. No transfers of shares shall be
recognized or binding upon the Corporation until recorded on the transfer books

of such shares or by his legal representative, or by his attorney thereunto
authorized by power of attorney duly executed. The person in whose name shares


<PAGE>   7
shall stand on the books of the Corporation may be deemed by the Corporation the
owner thereof for all purposes. The Corporation's transfer agent shall maintain
a stock transfer book, shall record therein all stock transfers and shall
forward copies of all transfer sheets at regular prompt intervals to the
Corporation's registrar, if there be one, or, if not, then to the Corporation's
principal office for transcription on the stock registry books.

Directors may fix a date not exceeding forty (40) days preceding the date of any
meeting of shareholders, any dividend payment date or any date for the allotment
of rights, as a record date for the determination of the shareholders entitled
to notice of and to vote at such meeting, or entitled to receive such dividends
or rights, as the case may be, and only shareholders of record on such date
shall be entitled to notice of and to vote at such meeting or to receive such
dividends or rights, as the case may be. In the case of a meeting of
shareholders, the record date shall be fixed not less than ten (10) days prior

upon such other terms and conditions as the Board of Directors may deem
advisable.

given to each shareholder, whether or not such shareholder is entitled to vote,
by leaving the same with him or at his residence or usual place of business, or
by mailing it, postage prepaid, and addressed to him at his address as it
appears on the books of the Corporation. Such leaving or mailing of notice shall
be deemed the time of giving such notice.

                          FUND PARTICIPATION AGREEMENT
                         ----------------------------


         AGREEMENT, made on this 16th day of September, 1992, between ANCHOR
NATIONAL LIFE INSURANCE COMPANY ("Anchor"), a life insurance company organized
under the laws of the State of California, on behalf of itself and on behalf of
VARIABLE SEPARATE ACCOUNT (f/k/a "AMERICAN PATHWAY II - SEPARATE ACCOUNT OF
ANCHOR NATIONAL LIFE INSURANCE COMPANY," ("Variable Account"), a separate
account of Anchor existing pursuant to the laws of the State of California, and
SUNAMERICA SERIES TRUST ("Fund"), an open-end management investment company
established pursuant to the laws of the Commonwealth of Massachusetts under a
Declaration of Fund dated September 11, 1992, which is composed of multiple
investment series ("Portfolios").


                                   WITNESSETH:


         WHEREAS, Anchor, by resolution, has established the Variable Account on
its books of account for the purpose of funding certain variable annuity
contracts issued by it; and

         WHEREAS, the Variable Account is divided into various portfolios
("Divisions") under which the income, gains and losses, whether or not realized,
from assets allocated to each such Division are, in accordance with the
applicable variable annuity contracts, credited to or charged against such
Division without regard to any income, gains or losses of other Divisions or
separate accounts of Anchor; and

         WHEREAS, the Variable Account is registered with the Securities and
Exchange Commission as a unit investment trust under the Investment Company Act
of 1940 ("Act"); and

         WHEREAS, the Fund, a registered, open-end, diversified management
investment company, is divided into various Portfolios, each Portfolio being
subject to separate investment objectives and restrictions which may not be
changed without a majority vote of the shareholders of each such Portfolio; and

         WHEREAS, the Variable Account desires to purchase shares of the Fund in
connection with the issuance of certain variable annuity contracts to be
marketed under the name Polaris (collectively with other contracts and policies
that may be funded through the Fund, "Contracts"); and

         WHEREAS, the Fund agrees to make shares of certain of its Portfolios
available to serve as underlying investment media for the corresponding
Divisions of the Variable Account; and

<PAGE>   2
         WHEREAS, SUNAMERICA SECURITIES, INC., and ROYAL ALLIANCE ASSOCIATES,
INC. (collectively, "Distributors"), which serve as the distributors for the
Contracts funded in the Variable Account pursuant to an agreement with Anchor on
behalf of itself and the Variable Account are each a broker-dealer registered as
such under the Securities Exchange Act of 1934 and a member of the National
Association of Securities Dealers, Inc.;

         NOW, THEREFORE, in consideration of the foregoing and of mutual
covenants and conditions set forth herein and for other good and valuable
consideration, Anchor (on behalf of itself and the Variable Account) and the
Fund hereby agree as follows:

         1. The Contracts funded by the Variable Account will provide for the
allocation of net amounts among certain Divisions of the Variable Account for
investment in the shares of the particular portfolio of the Fund underlying each
such Division. The selection of a particular Division is to be made (and such
selection may be changed) in accordance with the terms of the applicable
Contract.

         2. No representation is made as to the number or amount of such
Contracts to be sold. Anchor, pursuant to its agreement with Distributors, will
make reasonable efforts to market those Contracts it determines from time to
time to offer for sale and, although it is not required to offer for sale new
Contracts, Anchor will accept payments and otherwise service existing Contracts
funded in the Variable Account.

         3. Fund shares to be made available to the respective Divisions of the
Variable Account shall be sold by each of the respective Portfolios of the Fund
and purchased by Anchor for that Division at the net asset value next computed
after receipt of each order, as established in accordance with the provisions of
the then current prospectus of the Fund. Shares of a particular Portfolio of the
Fund shall be ordered in such quantities and at such times as determined by
Anchor to be necessary to meet the requirements of those Contracts having
amounts allocated to the Division for which the Fund Portfolio shares serve as
the underlying investment medium. Orders and payments for shares purchased will
be sent promptly to the Fund and will be made payable in the manner established
from time to time by the Fund for the receipt of such payments. The Fund
reserves the right to delay transfer of its shares until the payment check has
cleared. The Fund has the obligation to insure that its shares to be made
available to the appropriate Division(s) under the Contracts are registered at
all times under the Securities Act of 1933 ("1933 Act").

         4. The Fund will redeem the shares of the various Portfolios when
requested by Anchor on behalf of the corresponding Division of the Variable
Account at the net asset value next computed after receipt of each request for
redemption, as established in accordance with the provisions of the then current
prospectus of



                                      - 2 -


<PAGE>   3
the Fund. The Fund will make payment in the manner established from time to time
by the Fund for the receipt of such redemption requests, but in no event shall
payment be delayed for a greater period than is permitted by the Act.

         5. Transfer of the Fund's shares will be by book entry only. No stock
certificates will be issued to the Variable Account. Shares ordered from a
particular Portfolio to the Fund will be recorded in an appropriate title for
the corresponding Division of the Variable Account.

         6. The Fund shall furnish notice promptly to Anchor of any dividend or
distribution payable on its shares which are subject to this Agreement. All of
such dividends and distributions as are payable on each of the Portfolio shares
in the title for the corresponding Division of the Variable Account shall be
automatically reinvested in additional shares of that Portfolio of the Fund. The
Fund shall notify Anchor of the number of shares so issued.

         7. All expenses incident to the performance of the Fund under this
Agreement shall be paid by the Fund. The Fund shall ensure that all of its
shares which are subject to this Agreement are registered and authorized for
issue in accordance with applicable federal and state laws prior to their
purchase by the Variable Account. Anchor shall bear none of the expenses for the
cost of registration of the Fund's shares, preparation of the Fund's
prospectuses, proxy materials and reports, the distribution of such items to
shareholders,, the preparation of all statements and notices required by any
federal or state law or any taxes on the issue or transfer of the Fund's shares
subject to this Agreement.

         8. Anchor, either directly or through Distributors, shall make no
representations concerning the Fund's shares which are subject to this Agreement
other than those contained in the then current prospectus of the Fund and in
printed information subsequently issued by the Fund as supplemental to such
prospects.

         9. Anchor and the Fund acknowledge that in the future, the Fund's
shares may become available for investment by separate accounts of other
insurance companies, which may or may not be affiliated persons (as that term is
defined in the Act) of Anchor (collectively with Anchor, "Participating
Insurers"). In such event, (a) the Fund shall undertake that its Board of
Trustees ("Board") will monitor the Fund for the existence of material
irreconcilable conflicts that may arise between the Contract owners of
Participating Insurers, for the purpose of identifying and remedying any such
conflict and (b) paragraphs 10, 11 and 12 shall apply. In discharging its
responsibilities under paragraphs 10, 11 and 12 hereinafter, Anchor will
cooperate and coordinate, to the extent necessary, with the Board and with other
Participating



                                      - 3 -


<PAGE>   4
Insurers. The Fund agrees that it will require, as a condition to participation,
that all Participating Insurers shall have obligations and responsibilities
regarding conflicts of interest corresponding to those that are agreed to herein
by Anchor pursuant to such paragraphs 10, 11 and 12 and pursuant to this
paragraph 9.

         10. Anchor shall provide pass-through voting privileges to all variable
Contract owners so long as the U. S. Securities and Exchange Commission
continues to interpret the Act to require passthrough voting privileges for
variable Contract owners. Anchor shall be responsible for assuring that the
Variable Account calculates voting privilege in a manner consistent with
separate accounts of other Participating Insurers, as determined by the Board.
Anchor will vote shares for which it has not received voting instructions in the
same proportion as it votes shares for which it has received instructions.

         11. Anchor will report to the Board any potential or existing conflicts
of which it is or becomes aware between any of its Contract owners or between
any of its Contract owners and Contract owners of other Participating Insurers.
Anchor will be responsible for assisting the Board in carrying out its
responsibilities to identify material conflicts by providing the Board with all
information available to it that is reasonably necessary for the Board to
consider any issues raised, including information as to a decision by Anchor to
disregard voting instructions of its Contract owners.

         12. The Board's determination of the existence of an irreconcilable
material conflict and its implications shall be made known promptly by it to
Anchor and other Participating Insurers. An irreconcilable material conflict may
arise for a variety of reasons, including: (a) an action by any state insurance
regulatory authority; (b) a change in applicable federal or state insurance tax,
or securities laws or regulations, or a public ruling, private letter ruling, or
any similar action by insurance, tax, or securities regulatory authorities; (c)
an administrative or judicial decision in any relevant proceeding; (d) the
manner in which the investments of any Portfolio are being managed; (e) a
difference in voting instructions given by variable annuity Contract owners and
variable life insurance Contract owners or by Contract owners of different
Participating Insurers; or (f) a decision by a Participating Insurer to
disregard the voting instructions of variable Contract owners.

         13. If it is determined by a majority of the Board or a majority of its
disinterested Trustees that a material irreconcilable conflict exists that
affects the interests of Anchor Contract owners, Anchor shall, in cooperation
with other Participating Insurers whose Contract owners' interests are also
affected by the conflict, take whatever steps are necessary to remedy or
eliminate the irreconcilable material conflict, which



                                    - 4 -


<PAGE>   5
steps could include: (a) withdrawing the assets allocable to the Variable
Account from the Fund or any portfolio and reinvesting such assets in a
different investment medium, including another Portfolio of the Fund, or
submitting the question of whether such segregation should be implemented to a
vote of all affected Contract owners and, as appropriate, segregating the assets
of any particular group (e.g., annuity Contract owners or life insurance
Contract owners) that votes in favor of such segregation, or offering to the
affected Contract owners of the option of making such a change; and (b)
establishing a new registered management investment company or managed separate
account. Anchor shall take such steps at its expense if the conflict affects
solely the interests of the owners of Anchor Contracts, but shall bear only its
equitable portion of any such expense if the conflict also affects the interest
of the Contract owners of one or more Participating Insurers other than Anchor,
provided: that this sentence shall not be construed to require the Fund to bear
any portion of such expense. If a material irreconcilable conflict arises
because of Anchor's decision to disregard Contract owner voting instructions and
that decision represents a minority position or would preclude a majority vote,
Anchor may be required, at Fund's election, to withdraw the Variable Account's
investment in the Fund, and no charge or penalty will be imposed against the
Variable Account as a result of such a withdrawal. Anchor agrees to take such
remedial action as may be required under this paragraph 13 with a view only to
the interests of its Contract owners. For purposes of this paragraph 13, a
majority of the disinterested members of the Board shall determine whether or
not any proposed action adequately remedies any irreconcilable conflict, but in
no event will Fund be required to establish a new funding medium for any
variable Contracts. Anchor shall not be required by this paragraph 13 to
establish a new funding medium for any variable Contract if an offer to do so
has been declined by vote of a majority of affected Contract owners.

                  14.      This Agreement shall terminate:

                           (a)      at the option of Anchor or the Fund upon 60
                                    days' advance written notice to all other
                                    parties to this Agreement; or

                           (b)      at the option of Anchor if any of the Fund's
                                    shares are not reasonably available to meet
                                    the requirements of the Contracts funded in
                                    the Variable Account as determined by
                                    Anchor. Prompt notice of election to
                                    terminate shall be furnished by Anchor; or

                           (c)      at the option of Anchor upon institution of
                                    formal proceedings against the Fund by the
                                    Securities and Exchange Commission; or

                           (d)      upon the vote of Contract owners having an
                                    interest in a particular Division of the
                                    variable Account to substitute the shares of
                                    another investment company for the
                                    corresponding Fund Portfolio shares in
                                    accordance with the terms of the Contracts
                                    for which those Fund shares had been
                                    selected to serve as the underlying
                                    investment medium.  Anchor will give 30
                                    days' prior written notice to the Fund of
                                    the date of any proposed action to replace
                                    the Fund's shares; or

                           (e)      in the event the Fund's shares are not
                                    registered, issued or sold in accordance
                                    with applicable state and/or federal law or
                                    such law precludes the use of such shares as
                                    the underlying investment medium of the
                                    Contracts funded in the Variable Account.
                                    Prompt notice shall be given by each party
                                    to all other parties in the event that the
                                    conditions stated in subsections (b), (c) or
                                    (d) of this paragraph 14 should occur.

         15. Notwithstanding any other provisions of this Agreement, the
obligations of the Fund hereunder are not personally binding upon any of the
trustees, shareholders, officers, employees or agents of the Fund; resort in
satisfaction of such obligations shall be had only to the assets and property of
the Fund and not to the private property of any of such Fund's trustees,
shareholders, officers, employees or agents.

         16. This Agreement shall be construed in accordance with the laws of
the State of California.

         NOW, THEREFORE, in consideration of the foregoing and of mutual

established from time to time by the Fund for the receipt of such payments. The
Fund reserves the right to delay transfer of its shares until the payment check
has cleared. The Fund has the obligation to insure that its shares to be made
available to the appropriate Division(s) under the Contracts are registered at
all times under the Securities Act of 1933 ("1933 Act").

         4. The Fund will redeem the shares of the various Portfolios when
requested by Anchor on behalf of the corresponding Division of the Variable
Account at the net asset value next computed after receipt of each request for
redemption, as established in accordance with the provisions of the then current

from time to time by the Fund for the receipt of such redemption requests, but
in no event shall payment be delayed for a greater period than is permitted by
the Act.

         5. Transfer of the Fund's shares will be by book entry only. No stock
certificates will be issued to the Variable Account. Shares ordered from a
particular Portfolio to the Fund will be recorded in an appropriate title for
the corresponding Division of the Variable Account.

         6. The Fund shall furnish notice promptly to Anchor of any dividend or
distribution payable on its shares which are subject to this Agreement. All of
such dividends and distributions as are payable on each of the Portfolio shares
in the title for the corresponding Division of the Variable Account shall be
automatically reinvested in additional shares of that Portfolio of the Fund. The
Fund shall notify Anchor of the number of shares so issued.

         7. All expenses incident to the performance of the Fund under this
Agreement shall be paid by the Fund. The Fund shall ensure that all of its
shares which are subject to this Agreement are registered and authorized for
issue in accordance with applicable federal and state laws prior to their
purchase by the Variable Account. Anchor shall bear none of the expenses for the
cost of registration of the Fund's shares, preparation of the Fund's
prospectuses, proxy materials and reports, the distribution of such items to
shareholders, the preparation of all statements and notices required by any
federal or state law or any taxes on the issue or transfer of the Fund's shares
subject to this Agreement.

         8. Anchor, either directly or through Distributors, shall make no
representations concerning the Fund's shares which are subject to this Agreement
other than those contained in the then current prospectus of the Fund and in
printed information subsequently issued by the Fund as supplemental to such
prospects.

         9. Anchor shall provide pass-through voting privileges to all variable
Contract owners so long as the U. S. Securities and Exchange Commission
continues to interpret the Act to require passthrough voting privileges for
variable Contract owners. Anchor shall be responsible for assuring that the
Variable Account calculates voting privilege in a manner consistent with
separate accounts of other insurance companies that are invested in the Fund,
which other insurance companies may or may not be affiliated with Anchor
(collectively with Anchor, "Participating Insurers"), as determined by the
Board. Anchor will vote shares for which it has not received voting instructions
in the same proportion as it votes shares for which it has received
instructions.

         10. Anchor will report to the Board any potential or existing conflicts
of which it is or becomes aware between any of its Contract owners, or between
any of its Contract owners and Contract owners of other Participating Insurers.
Anchor will be responsible for assisting the Board in carrying out its
responsibilities to identify material conflicts by providing the Board with all
information available to it that is reasonably necessary for the Board to
consider any issues raised, including information as to a decision by Anchor to
disregard voting instructions of its Contract owners.

         11. The Board's determination of the existence of an irreconcilable
material conflict and its implications shall be made known promptly by it to
Anchor and other Participating Insurers. An irreconcilable material conflict may
arise for a variety of reasons, including: (a) an action by any state insurance
regulatory authority; (b) a change in applicable federal or state insurance tax,
or securities laws or regulations, or a public ruling, private letter ruling, or
any similar action by insurance, tax, or securities regulatory authorities; (c)
an administrative or judicial decision in any relevant proceeding; (d) the
manner in which the investments of any Portfolio are being managed; (e) a
difference in voting instructions given by variable annuity Contract owners and
variable life insurance Contract owners or by Contract owners of different
Participating Insurers; or (f) a decision by a Participating Insurer to
disregard the voting instructions of variable Contract owners.

         12. If it is determined by a majority of the Board or a majority of its
disinterested Trustees that a material irreconcilable to conflict exists that
affects the interests of Anchor Contract owners, Anchor shall, in cooperation
with other Participating Insurers whose Contract owners' interests are also
affected by the conflict, take whatever steps are necessary to remedy or
eliminate the irreconcilable material conflict, which steps could include: (a)
withdrawing the assets allocable to the Variable Account from the Fund or any
portfolio and reinvesting such assets in a different investment medium,
including another Portfolio of the Fund, or submitting the question of whether
such



                                      - 4 -


<PAGE>   12
segregation should be implemented to a vote of all affected Contract owners and,
as appropriate, segregating the assets of any particular group (e.g., annuity
Contract owners or life insurance Contract owners) that votes in favor of such
segregation, or offering to the affected Contract owners of the option of making
such a change; and (b) establishing a new registered management investment
company or managed separate account. Anchor shall take such steps at its expense
if the conflict affects solely the interests of the owners of Anchor Contracts,
but shall bear only its equitable portion of any such expense if the conflict
also affects the interest of the Contract owners of one or more Participating
Insurers other than Anchor, provided: that this sentence shall not be construed
to require the Fund to bear any portion of such expense. If a material
irreconcilable conflict arises because of Anchor's decision to disregard
Contract owner voting instructions and that decision represents a minority
position or would preclude a majority vote, Anchor may be required, at Fund's
election, to withdraw the Variable Account's investment in the Fund, and no
charge or penalty will be imposed against the Variable Account as a result of
such a withdrawal. Anchor agrees to take such remedial action as may be required
under this paragraph 12 with a view only to the interests of its Contract
owners. For purposes of this paragraph 12, a majority of the disinterested
members of the Board shall determine whether or not any proposed action
adequately remedies any irreconcilable conflict, but in no event will Fund be
required to establish a new funding medium for any variable Contracts. Anchor
shall not be required by this paragraph 12 to establish a new funding medium for
any variable Contract if an offer to do so has been declined by vote of a
majority of affected Contract owners.

         13. In discharging its responsibilities under paragraphs 9, 10 and 12
hereinabove, Anchor will cooperate and coordinate, to the extent necessary, with
the Board and with other participating Insurers. The Fund agrees that it will
require, as a condition to participation, that all Participating Insurers shall
have obligations and responsibilities regarding conflicts of interest
corresponding to those that are agreed to herein by Anchor pursuant to such
paragraphs 9, 10 and 12 and pursuant to this paragraph 13.

         14. This Agreement shall terminate:

                  (a)      at the option of Anchor or the Fund upon 60 days'
                           advance written notice to all other parties to this
                           Agreement; or

                  (b)      at the option of Anchor if any of the Fund's shares
                           are not reasonably available to meet the requirements
                           of the Contracts funded in the Variable Account as
                           determined by Anchor. Prompt notice of election to
                           terminate shall be furnished by Anchor; or

                  (c)      at the option of Anchor upon institution of formal
                           proceedings against the Fund by the Securities and
                           Exchange Commission; or

                  (d)      upon the vote of Contract owners having an interest
                           in a particular Division of the Variable Account to
                           substitute the shares of another investment company
                           for the corresponding Fund Portfolio shares in
                           accordance with the terms of the Contracts for which
                           those Fund shares had been selected to serve as the
                           underlying investment medium.  Anchor will give 30
                           days' prior written notice to the Fund of the date of
                           any proposed action to replace the Fund's shares; or

                  (e)      in the event the Fund's shares are not registered,
                           issued or sold in accordance with applicable state
                           and/or federal law or such law precludes the use of
                           such shares as the underlying investment medium of
                           the Contracts funded in the Variable Account.  Prompt
                           notice shall be given by each party to all other
                           parties in the event that the conditions stated in
                           subsections (b), (c) or (d) of this paragraph 14
                           should occur.

         15. Notwithstanding any other provisions of this Agreement, the
obligations of the Fund hereunder are not personally binding upon any of the
trustees, shareholders, officers, employees or agents of the Fund; resort in
satisfaction of such obligations shall be had only to the assets and property of
the Fund and not to the private property of any of such Fund's trustees,
shareholders, officers, employees or agents.

         16. This Agreement shall be construed in accordance with the laws of
the State of California.

                         OPINION AND CONSENT OF COUNSEL


        Having examined and being familiar with the articles of incorporation
and by-laws of Anchor National Life Insurance Company ("Anchor National"), the
applicable resolutions relating to Variable Separate Account (the "Account"),
and other pertinent records and documents, it is our opinion that (i) Anchor
National is a duly organized and existing stock life insurance company under
the laws of the State of California; (ii) the Account is a duly organized and
existing Separate Account of Anchor National and is registered as a unit
investment trust under the Investment Company Act of 1940 (File No. 811-3859);
and (iii) the variable annuity contracts being registered by this Registration
Statement under the Securities Act of 1933 (File No. 33-47473) will, upon
issuance thereof, be legally issued and respresent binding obligations of
Anchor National.

        We hereby consent to the use of our Opinion of Counsel in the
Registration Statement on Form N-4 on behalf of the Account.
