                              [POLARIS 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 ANNUITY IS
MORE FULLY DESCRIBED IN THE PROSPECTUS. PLEASE READ THE PROSPECTUS CAREFULLY.

                                  May 1, 2000


- ----------------------------------------------------------------
- ----------------------------------------------------------------
                        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 27 variable portfolios and 5 fixed
account options. To the extent you invest in the variable portfolios, your
investment is not guaranteed. The value of your Polaris contract can fluctuate
up and down, based on the performance of the underlying investments you select
and you may experience a loss.

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

The contract also offers 5 fixed account options, for different time periods.
Each may have a different interest rate. Interest rates are guaranteed by Anchor
National.

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

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

You can select from one of five income options:

   (1) payments for your lifetime;

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

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

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

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

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

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

- ----------------------------------------------------------------
- ----------------------------------------------------------------
                        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
purchase payment is $5,000 and subsequent amounts of $500 or more may be added
to your contract at any time during the accumulation phase. For qualified
contracts, the minimum initial purchase payment is $2,000 and subsequent amounts
of $250 or more may be added to your contract at any time during the
accumulation phase.

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

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

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


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


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

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

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

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


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


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

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

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

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

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

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

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

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

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

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

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 at the time we receive satisfactory proof of
    death; or

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

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

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

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

PRINCIPAL ADVANTAGE PROGRAM: If selected by you, this program allows you to
obtain growth potential without any
<PAGE>   8

market risk to your principal. We will guarantee that the portion of your money
allocated to the 1, 3, 5, 7 or 10-year fixed account option will grow to equal
your principal investment when it is allocated in accordance with the program.

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

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


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

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

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

EXPLANATION OF FEE TABLES AND EXAMPLES

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

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

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

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

                          THE POLARIS VARIABLE ANNUITY
- ----------------------------------------------------------------
- ----------------------------------------------------------------

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

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

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

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

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

The contract is called a "variable" annuity because it allows you to invest in
variable portfolios which, like mutual funds, have different investment
objectives and performance which varies. You can gain or lose money if you
invest in these Variable Portfolios. The amount of money you accumulate in your
contract depends on the performance of the Variable Portfolios in which you
invest. This contract currently offers 27 Variable Portfolios.

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

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

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

Prior Company approval is required to accept Purchase Payments greater than
$1,500,000. The Company reserves the right to refuse any Purchase Payment
including, but not limited to, one which would cause the contract value to
exceed $1,500,000 at the time of the Purchase Payment. Also, the optional
automatic payment plan allows you to make subsequent Purchase Payments of as
little as $20.00.


                                        6

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

ALLOCATION OF PURCHASE PAYMENTS

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

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

     - Send your money back to you, or;

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

ACCUMULATION UNITS

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

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

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

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

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

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

     EXAMPLE:

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

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

FREE LOOK

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

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

VARIABLE PORTFOLIOS

The contract currently offers 27 Variable Portfolios. These Variable Portfolios
invest in shares of the Anchor Series Trust and the SunAmerica Series Trust (the
"Trusts"). Additional portfolios may be available in the future. The Variable
Portfolios operate similarly to a mutual fund but are only available through the
purchase of certain insurance contracts.

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

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

FIXED ACCOUNT OPTIONS

The contract also offers five fixed account options. Anchor National will
guarantee the interest rate earned on money you allocate to any of these fixed
account options. We currently offer fixed account options for periods of one,
three, five, seven and ten years, which we call guarantee periods.

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

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

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

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

     - Renewal Rate: Rate credited to money transferred from one fixed account
       or one of the Variable Portfolios to another fixed account.

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

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

MARKET VALUE ADJUSTMENT ("MVA")

NOTE: THE FOLLOWING DISCUSSION APPLIES TO THE 3, 5, 7 AND 10-YEAR FIXED ACCOUNT
OPTIONS, ONLY.

If you take money out of the multi-year fixed account options before the end of
the guarantee period, we make an adjustment to your contract. We refer to the
adjustment as a market value adjustment (the "MVA"). The MVA reflects any
difference in the interest rate environment between the

                                        8
<PAGE>   17

time you place your money in the fixed account option and the time when you
withdraw that money. This adjustment can increase or decrease your contract
value. You have 30 days after the end of each guarantee period to reallocate
your funds without incurring any MVA.

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

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

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

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

     - If made within 30 days after the end of a guarantee period;

     - If made to pay contract fees and charges;

     - To pay a death benefit; and

     - If annuitization occurs on the latest Annuity Date.

The 1-year fixed account option does not impose a MVA. This fixed account option
is not registered under the Securities Act of 1933 and is not subject to the
provisions of the Investment Company Act of 1940.

APPENDIX B shows how we calculate the MVA.

TRANSFERS DURING THE ACCUMULATION PHASE

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

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

We accept transfer requests by telephone unless you tell us not to on your
contract application. Additionally, in the future you may be able to execute
transfers or other financial transactions over the internet. When receiving
instructions over the telephone, we follow appropriate procedures to provide
reasonable assurance that the transactions executed are genuine. Thus, we are
not responsible for any claim, loss or expense from any error resulting from
instructions received over the telephone.

Upon implementation of internet account transactions we will have appropriate
procedures in place to provide reasonable assurance that the transactions
executed are genuine. Thus, we would not be responsible for any claim, loss or
expense from any error resulting from instructions received over the internet.
If we fail to follow our procedures, we may be liable for any losses due to
unauthorized or fraudulent instructions.

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

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

     - such third party has been appointed by a court of competent jurisdiction
       to act on your behalf; or

     - such third party is a trustee/fiduciary, for you or appointed by you, to
       act on your behalf for all your financial affairs.

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

                                        9
<PAGE>   18

OR FOR ANY INVESTMENT ALLOCATION RECOMMENDATIONS MADE BY SUCH PARTIES.

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

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

DOLLAR COST AVERAGING

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

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

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

     EXAMPLE:

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

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

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

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

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

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

     EXAMPLE:

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

PRINCIPAL ADVANTAGE PROGRAM

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

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

     EXAMPLE:

     Assume that you want to allocate a portion of your initial Purchase Payment
     of $100,000 to the fixed account option. You want the amount allocated to
     the fixed

                                       10
<PAGE>   19

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

VOTING RIGHTS

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

SUBSTITUTION

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

- ----------------------------------------------------------------
- ----------------------------------------------------------------
                              ACCESS TO YOUR MONEY
- ----------------------------------------------------------------
- ----------------------------------------------------------------

You can access money in your contract in two ways:

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

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

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

Your contract provides for a free withdrawal amount. A free withdrawal amount is
the portion of your account that we allow you to take out each year without
being charged a withdrawal charge.

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, you may withdraw the greater of the following amounts free
of a withdrawal charge (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 previous earnings withdrawals or Systematic
Withdrawals that year.
Only your first withdrawal of the year is free. If you do not take the entire
free amount available to you at that first withdrawal, you will forfeit the
opportunity to withdraw that money free of the withdrawal charge for that year.

The portion of a free withdrawal which exceeds the sum of: (1) earnings in the
contract and (2) Purchase Payments which are 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 withdraw your
entire contract value.

However, upon a future full surrender of your contract, we will recoup any
withdrawal charges which would have been applicable if your free withdrawal(s)
had not been free.

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

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

Under certain Qualified plans, access to the money in your contract may be
restricted. Additionally, withdrawals made prior to age 59 1/2 may result in a
10% IRS penalty tax. SEE TAXES ON PAGE 15.

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

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

SYSTEMATIC WITHDRAWAL PROGRAM

During the Accumulation Phase, you may elect to receive periodic income payments
under the systematic withdrawal program. Under the program, you may choose to
take monthly, quarterly, semi-annual or annual payments from your contract.
Electronic transfer of these funds to your bank account is also available. The
minimum amount of each withdrawal is $250. There must be at least $500 remaining
in your contract at all times. Withdrawals may be taxable and a 10% IRS penalty
tax may apply if you are under age 59 1/2.

                                       11
<PAGE>   20

There is no additional charge for participating in this program, although a
withdrawal charge and/or MVA may apply.

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

NURSING HOME WAIVER

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

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

MINIMUM CONTRACT VALUE

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

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

If you die during the Accumulation Phase of your contract, we pay a death
benefit to your Beneficiary.

The death benefit is the greater of:

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

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

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

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

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

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

     1. a certified copy of the death certificate; or

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

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

     4. any other proof satisfactory to us.

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

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

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

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

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

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

INSURANCE CHARGES

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

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

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

WITHDRAWAL CHARGES

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

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

<TABLE>

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

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

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

We will not assess a withdrawal charge for money withdrawn to pay a death
benefit or to pay contract fees or charges. Additionally, we will not assess a
withdrawal charge when you switch to the Income Phase.

Withdrawals made prior to age 59 1/2 may result in tax penalties. SEE TAXES ON
PAGE 15.
INVESTMENT CHARGES

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

CONTRACT MAINTENANCE FEE

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

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

TRANSFER FEE

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

PREMIUM TAX

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

APPENDIX C provides more information about premium taxes.

INCOME TAXES

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

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

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

                                       13
<PAGE>   22

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

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

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

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

ANNUITY DATE

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

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

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

In addition, most Qualified contracts require you to take minimum distributions
after you reach age 70 1/2. SEE TAXES ON PAGE 15.

INCOME OPTIONS

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

We base our calculation of income payments on the life of the Annuitant and the
annuity rates set forth in your contract. As the contract owner, you may change
the Annuitant at any time prior to the Annuity Date. You must notify us if the
Annuitant dies before the Annuity Date and designate a new Annuitant.
     OPTION 1 - LIFE INCOME ANNUITY

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

     OPTION 2 - JOINT AND SURVIVOR LIFE ANNUITY

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

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

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

     OPTION 4 - LIFE ANNUITY WITH 10 OR 20 YEARS GUARANTEED

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

     OPTION 5 - INCOME FOR A SPECIFIED PERIOD

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

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

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

FIXED OR VARIABLE INCOME PAYMENTS

You can choose income payments that are fixed, variable or both. If at the date
when income payments begin you are invested in the Variable Portfolios only,
your income payments will be variable. If your money is only in fixed accounts
at that time, your income payments will be fixed in amount. Further, if you are
invested in both fixed and variable investment options when income payments
begin, your

                                       14
<PAGE>   23

payments will be fixed and variable. If income payments are fixed, Anchor
National guarantees the amount of each payment. If the income payments are
variable the amount is not guaranteed.

INCOME PAYMENTS

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

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

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

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

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

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

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

TRANSFERS DURING THE INCOME PHASE

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

DEFERMENT OF PAYMENTS

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

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

ANNUITY CONTRACTS IN GENERAL

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

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

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

TAX TREATMENT OF DISTRIBUTIONS -
NON-QUALIFIED CONTRACTS

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

TAX TREATMENT OF DISTRIBUTIONS - QUALIFIED CONTRACTS

Generally, you have not paid any taxes on the Purchase Payments used to buy a
Qualified contract. Any amount of money you take out as a withdrawal or as
income payments is taxable income. The IRC further provides for a 10% penalty
tax on any withdrawal or income payment paid to you other than in conjunction
with the following circumstances:

                                       15
<PAGE>   24

(1) after reaching age 59 1/2; (2) when paid to your Beneficiary after you die;
(3) after you become disabled (as defined in the IRC); (4) in a series of
substantially equal installments made for your life or for the joint lives of
you and your Beneficiary; (5) to the extent such withdrawals do not exceed
limitations set by the IRC for amounts paid during the taxable year for medical
care; (6) to fund higher education expenses (as defined in IRC); (7) to fund
certain first-time home purchase expenses; and, except in the case of an IR; (8)
when you separate from service after attaining age 55; and (9) when paid to an
alternate payee pursuant to a qualified domestic relations order.

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

MINIMUM DISTRIBUTIONS

Generally, the IRS requires that you begin taking annual distributions from
qualified annuity contracts by April 1 of the calendar year following the later
of (1) the calendar year in which you attain age 70 1/2 or (2) the calendar year
in which you retire. Failure to satisfy minimum distribution requirements may
result in a tax penalty. You should consult your tax advisor for more
information.

DIVERSIFICATION

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

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

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

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

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

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

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

ANCHOR NATIONAL

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

                                       16
<PAGE>   25

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

THE SEPARATE ACCOUNT

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

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

THE GENERAL ACCOUNT

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

DISTRIBUTION OF THE CONTRACT

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

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

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

ADMINISTRATION

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

We send out transaction confirmations and quarterly statements. It is your
responsibility to review these documents carefully and notify us of any
inaccuracies immediately. We investigate all inquiries. To the extent that we
believe we made an error, we retroactively adjust your contract, provided you
notify us within 30 days of receiving the transaction confirmation or quarterly
statement. Any other adjustments we deem warranted are made as of the time we
receive notice of the error.

YEAR 2000


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



LEGAL PROCEEDINGS


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

OWNERSHIP

The Polaris Variable Annuity is a Flexible Payment Group Deferred Annuity
contract. We issue a group contract to a contract holder for the benefit of the
participants in the group. As a participant in the group, you will receive a

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

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

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

                  The MVA formula may differ in certain states
  where:

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

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

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

EXAMPLES OF THE MVA

The examples below assume the following:

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

     (2) You make a partial withdrawal of $4,000 when 1 1/2 years (18 months)
         remain in the 10-year term you initially agreed to leave your money in
         the fixed account option (N=18); and

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

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

POSITIVE ADJUSTMENT

Assume that on the date of withdrawal, the interest rate in effect for a new
Purchase Payments in the 1-year fixed account option is 3.5% and the 3-year
fixed account option is 4.5%. By linear interpolation, the interest rate for the
remaining 2 years (1 1/2 years rounded up to the next full year) in the contract
is calculated to be 4%.

                                      N/12
The MVA factor is = [(1+I/(1+J+0.005)]     - 1
                                         18/12
                  = [(1.05)/(1.04+0.005)]      - 1
                              1.5
                  = (1.004785)    - 1
                  = 1.007186 - 1
                  = + 0.007186

The requested withdrawal amount is multiplied by the MVA factor to determine the
MVA:
                         $4,000 x (+0.007186) = +$28.74

$28.74 represents the MVA that would be added to your withdrawal.

NEGATIVE ADJUSTMENT

Assume that on the date of withdrawal, the interest rate in effect for new
Purchase Payments in the 1-year fixed account option is 5.5% and the 3-year
fixed account option is 6.5%. By linear interpolation, the interest rate for the
remaining 2 years (1 1/2 years rounded up to the next full year) in the contract
is calculated to be 6%.

                                       N/12
The MVA factor is = [(1+I)/(1+J+0.005)]     - 1
                                         18/12
                  = [(1.05)/(1.06+0.005)]      - 1
                              1.5
                  = (0.985915)    - 1
                  = 0.978948 - 1
                  = - 0.021052

The requested withdrawal amount is multiplied by the MVA factor to determine the
MVA:
                        $4,000 X (- 0.021052) = -$84.21

$84.21 represents the MVA that will be deducted from the money remaining in the
10-year fixed account option.

                                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 Variable Portfolios, with the
assets of each Variable Portfolio invested in the shares of one of the
underlying funds. The Company does not guarantee the investment performance of
the separate account, its Variable Portfolios or the underlying funds. Values
allocated to the separate account and the amount of variable Income 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 Income 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 Income 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
Variable 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 Income
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 Income
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 Income 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.


                                      -3-
<PAGE>   35


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 Cash Management
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 Cash Management 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 Variable 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 of return that, when
compounded annually over a stated period of time and applied to a hypothetical
initial investment in a Variable 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 Variable Portfolios first
became available through the separate account 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 underlying funds of Anchor Series Trust, modified to reflect
the charges and expenses as if the separate account Variable Portfolio had been
in existence since the inception date of each respective Anchor Series Trust
underlying fund. Thus, such performance figures should not be construed to be
actual historic performance of the relevant separate account Variable Portfolio.
Rather, they are intended to indicate the historic performance of the



                                      -4-

four corresponding underlying funds of Anchor Series Trust, adjusted to provide
direct comparability to the performance of the Variable Portfolios after the
date the Variable Portfolio became available within the separate account. The
Capital Appreciation, Growth, Natural Resources and Government and Quality Bond
underlying funds of Anchor Series 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 Variable 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 December 31, 1999 were 4.56%
and 4.66%, 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-CMF)/(SV)

         where:

                  SV  = value of one Accumulation Unit at the start of a 7 day
                        period
                  EV  = value of one Accumulation Unit at the end of the 7 day
                        period
                  CMF = an allocated portion of the $35 annual
                        Contract Maintenance Fee, 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 Maintenance Fee (CMF) is first allocated among the Variable
Portfolios and the general account so that each Variable Portfolio's allocated
portion of the fee is proportional to the percentage of the number of accounts
that have money allocated to that Variable 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.


                                      -5-
<PAGE>   37


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.

OTHER VARIABLE PORTFOLIOS
- -------------------------

         The Variable Portfolios of the separate account other than the Cash
Management Portfolio compute their performance data as "total return".


         The total returns of the various Variable Portfolios for 1 year period,
5-year period and since each Variable Portfolio's inception date are shown on
the next page, both with and without an assumed complete redemption at the end
of the period.

Total return figures are based on historical data and are not intended to
indicate future performance.

         Total return for a Variable 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
Variable 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


                                      -7-
<PAGE>   39


                  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 Maintenance Fees 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 Variable 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.

                                 INCOME PAYMENTS

INITIAL MONTHLY INCOME PAYMENTS
- -------------------------------

         The initial Income 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 Income 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 Income Payment. In the case of a variable annuity, that
amount is divided by the value of an Annuity Unit as of the Annuity Date to
establish the number of Annuity Units representing each variable Income Payment.
The number of Annuity Units determined for the first variable Income Payment
remains constant for the second and subsequent monthly variable Income Payments,
assuming that no reallocation of contract values is made.

SUBSEQUENT MONTHLY PAYMENTS
- ---------------------------

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

         For variable Income Payments, the amount of the second and each
subsequent monthly Income 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 Income Payment is due.


                                      -8-
<PAGE>   40


                               ANNUITY UNIT VALUES

         The value of an Annuity Unit is determined independently for each
Variable 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 Variable Portfolio exceed 3.5%, variable Income Payments derived from
allocations to that Variable Portfolio will increase over time. Conversely, if
the actual rate is less than 3.5%, variable Income Payments will decrease over
time. If the net investment rate equals 3.5%, the variable Income 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 Income 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 Variable Portfolios elected, and the amount of each Income
Payment will vary accordingly.

         For each Variable 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 Variable 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 Variable Portfolio for a certain month is determined by
dividing (a) by (b) where:

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

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

         The NIF for a Variable Portfolio for a given month is a measure of the
net investment performance of the Variable 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 Variable Portfolio; a NIF greater than 1.000 results from an
increase in the value of the Variable Portfolio; and a NIF less than 1.000
results from a decrease in the value of the Variable 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
Variable Portfolio invests; it is also reduced by separate account asset
charges.

         Illustrative Example
         --------------------

         Assume that one share of a given Variable 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


                                      -9-
<PAGE>   41

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 Variable 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 Variable 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 Income Payment tables
are based. For example, if the net investment rate for a Variable Portfolio
(reflected in the NIF) were equal to the assumed investment rate, the variable
Income 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 Variable
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

         To determine the initial payment, the initial annuity payment for
variable annuitization is calculated based on our mortality expectations and an
assumed interest rate (AIR) of 3.5%. Thus the initial variable annuity payment
is the same as the initial payment for a fixed interest payout annuity
calculated at an effective rate of 3.5%.

         The NIF measures the performance of the funds that are basis for the
amount of future annuity payments. This performance is compared to the AIR, and
if the growth in the NIF is the same as the AIR rate the payment remains the
same as the prior month. If the rate of growth of the NIF is different than the
AIR, then the payment is changed proportionately to the ratio (1+NIF) / (1+AIR),
calculated on a monthly basis. If the NIF is greater than the AIR, then this
proportion is less that one and payments are decreased.

VARIABLE INCOME 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 Variable 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 Variable Portfolio on that same date is
$13.256932, and that the Annuity Unit value on the day immediately prior to the
second Income Payment date is $13.327695.


                                      -10-
<PAGE>   42


         P's first variable Income Payment is determined from the annuity rate
tables in P's contract, using the information assumed above. From the tables,
which supply monthly Income Payments for each $1,000 of applied contract value,
P's first variable Income 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 Income 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 Income 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 Income Payments are computed in a
manner similar to the second variable Income Payment.

         Note that the amount of the first variable Income Payment depends on
the contract value in the relevant Variable Portfolio on the Annuity Date and
thus reflects the investment performance of the Variable 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 Variable Portfolio). The net investment
performance of the Variable 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 Income 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 income 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 income 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 income 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


                                      -11-
<PAGE>   43

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) income 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.

         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


                                      -12-
<PAGE>   44


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 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.


PARTIAL 1035 EXCHANGES
- ----------------------

      Section 1035 of the Code provides that an annuity contract may be
exchanged in a tax-free transaction for another annuity contract. Historically,
it was presumed that only the exchange of an entire contract, as opposed to a
partial exchange, would be accorded tax-free status. In 1998 in Conway vs.
Commissioner, the Tax Court held that the direct transfer of a portion of an
annuity contract into another annuity contract qualified as a non-taxable
exchange. On November 22, 1999, the Internal Revenue Service filed an Action on
Decision which indicated that it acquiesced in the Tax Court decision in
Conway. However, in its acquiescence with the decision of the Tax Court, the
Internal Revenue Service stated that it will challenge transactions where
taxpayers enter into a series of partial exchanges and annuitizations as part
of a design to avoid application of the 10% premature distribution penalty or
other limitations imposed on annuity contracts under Section 72 of the Code. In
the absence of further guidance from the Internal Revenue Service it is unclear
what specific types of partial exchange designs and transactions will be
challenged by the Internal Revenue Service. Due to the uncertainty in this area
owners should seek their own tax advice.


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


                                      -13-
<PAGE>   45


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 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)      Roth IRAs

                  Section 408(a) of the Code permits an individual to contribute
to an individual retirement program called a Roth IRA. Unlike contributions to a
regular IRA under Section 408(b) of the Code, contributions to a Roth IRA are
not made on a tax-deferred basis, but distributions are tax-free if certain
requirements are satisfied. Like regular IRAs, Roth IRAs are subject to
limitations on the amount that may be contributed, those who may be eligible and
the time when distributions may commence without tax penalty. Certain persons
may be eligible to convert a regular IRA into a Roth IRA, and the taxes on the
resulting income may be spread over four years if the conversion occurs before
January 1, 1999. If and when contracts are made available for use with Roth
IRAs, they may be subject to special requirements imposed by the Internal
Revenue Service ("IRS"). Purchasers of the contracts for this purpose will be
provided with such supplementary information as may be required by the IRS or
other appropriate agency.

         (E)      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


                                      -14-
<PAGE>   46


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.

         (F)      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. As of January 1, 1999, all 457 plans of state and
local governments must hold assets and income in trust (or custodial accounts
or an annuity contract) for the exclusive benefit of participants and their
Beneficiaries.

                            DISTRIBUTION OF CONTRACTS

         The contracts are offered on a continuous basis through SunAmerica

                          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.      NATURE OF OPERATIONS

        Anchor National Life Insurance Company, including its wholly owned
        subsidiaries, (the "Company") is an Arizona-domiciled life insurance
        company which conducts its business through three segments: annuity
        operations, asset management operations and broker-dealer operations.
        Annuity operations include the sale and administration of deposit-type
        insurance contracts, including fixed and variable annuities, universal
        life contracts and guaranteed investment contracts. Asset management
        operations, which include the distribution and management of mutual
        funds, are 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 Company is an indirect wholly owned subsidiary of American
        International Group, Inc. ("AIG"), an international insurance and
        financial services holding company. At December 31, 1998, the Company
        was a wholly owned indirect subsidiary of SunAmerica Inc., a Maryland
        Corporation. On January 1, 1999, SunAmerica Inc. merged with and into
        AIG in a tax-free reorganization that has been treated as a pooling of
        interests for accounting purposes. Thus, SunAmerica Inc. ceased to exist
        on that date. However, immediately prior to the date of the merger,
        substantially all of the net assets of SunAmerica Inc. were contributed
        to a newly formed subsidiary of AIG named SunAmerica Holdings, Inc., a
        Delaware Corporation. SunAmerica Holdings, Inc. subsequently changed its
        name to SunAmerica Inc. ("SunAmerica").

        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, the 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 items have been
        reclassified to conform to the current period's presentation.

2.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        Under generally accepted accounting principles, premiums collected on
        the non-traditional life and annuity insurance products, such as those
        sold by the Company, are not reflected as revenues in the Company's
        statement of earnings, as they are recorded directly to policyholders
        liabilities upon receipt.

        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.

        INVESTED ASSETS: 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. Policy loans are carried at unpaid
        balances. Separate account seed money consists of seed money for mutual
        funds used as investment vehicles for the Company's variable annuity
        separate accounts and is valued at market. Limited partnerships are
        accounted for by the cost method of accounting. Real estate is carried
        at cost, reduced by impairment provisions. Other invested assets include
        collateralized bond obligations.

        Realized gains and losses on the sale of investments are recognized in
        operations at the date of sale and are determined by using the specific
        cost identification method. Premiums and discounts on investments are
        amortized to investment income by 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
        Investment Income or Interest Expense in the income statement.
        Initially, Swap Agreements are designated as hedges and, therefore, are
        not marked to market. However, when a hedged asset/liability is sold or
        repaid before the related Swap Agreement matures, the Swap Agreement is
        marked to market and any gain/loss is classified with any gain/loss
        realized on the disposition of the hedged asset/liability. Subsequently,
        the Swap Agreement is marked to market and the resulting change in fair
        value is included in Investment Income in the income

        statement. When a Swap Agreement that is designated as a hedge is
        terminated before its contractual maturity, any resulting gain/loss is
        credited/charged to the carrying value of the asset/liability that it
        hedged and is treated as a premium/discount for the remaining life of
        the asset/liability.

        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,
        universal life insurance 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 ("DAC") 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 DAC 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 accumulated other comprehensive
        income/(loss) that is credited or charged directly to shareholder's
        equity. DAC has been increased by $29,400,000 at December 31, 1999,
        increased by $1,400,000 at December 31, 1998, and decreased by
        $7,000,000 at September 30, 1998 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 $22,206,000 at December 31, 1999, 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, universal life insurance 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).

        MODIFIED COINSURANCE DEPOSIT LIABILITY: Cash received as part of the
        modified coinsurance transaction described in Note 8 is recorded as a
        deposit liability.

2.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        FEE INCOME: Variable annuity fees, asset management fees, universal life
        insurance 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 files as a "life insurance company" under the
        provisions of the Internal Revenue Code of 1986. Its federal income tax
        return is consolidated with those of its direct parent, SunAmerica Life
        Insurance Company (the "Parent"), and its affiliate, First SunAmerica
        Life Insurance Company. 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.

        RECENTLY ISSUED ACCOUNTING STANDARDS: In June 1998, the FASB issued
        Statement of Financial Accounting Standards No. 133, "Accounting for
        Derivative Instruments and Hedging Activities" ("SFAS 133"). SFAS 133
        addresses the accounting for derivative instruments, including certain
        derivative instruments embedded in other contracts, and hedging
        activities. SFAS 133 was postponed by SFAS 137, and now will be
        effective for the Company as of January 1, 2001. Therefore, it is not
        included in the accompanying financial statements. The Company has not
        completed its analysis of the effect of SFAS 133, but management
        believes that it will not have a material impact on the Company's
        results of operations, financial condition or liquidity.

        Statement of Financial Accounting Standards No. 131, "Disclosures about
        Segments of an Enterprise and Related Information," was adopted for the
        year ended December 31, 1999 and is included in Note 14 of the
        accompanying financial statements.

3.      FISCAL YEAR CHANGE

        Effective December 31, 1998, the Company changed its fiscal year end
        from September 30 to December 31. Accordingly, the consolidated
        financial statements include the results of operations and cash flows
        for the three-month transition period ended December 31, 1998. Such
        results are not necessarily indicative of operations for a full year.
        The consolidated financial statements as of and for the three months
        ended December 31, 1998 were originally filed as the Company's unaudited
        Transition Report on Form 10-Q.

        Results for the comparable prior year period are summarized below.

4.      ACQUISITION

        On December 31, 1998, the Company acquired the individual life business
        and the individual and group annuity business of MBL Life Assurance
        Corporation ("MBL Life") ("the Acquisition"), via a 100% coinsurance
        transaction, for a cash purchase price of $128,420,000. As part of this
        transaction, the Company acquired assets having an aggregate fair value
        of $5,718,227,000, composed primarily of invested assets totaling
        $5,715,010,000. Liabilities assumed in this acquisition totaled
        $5,831,266,000, including $3,460,503,000 of fixed annuity reserves,
        $2,308,742,000 of universal life reserves and $24,011,000 of guaranteed
        investment contract reserves. The excess of the purchase price over the
        fair value of net assets received amounted to $104,509,000 at December
        31, 1999, after adjustment for the transfer of the New York business to
        First SunAmerica Life Insurance Company (see below), and is included in
        Deferred Acquisition Costs in the accompanying consolidated balance
        sheet. The income statement for the year ended December 31, 1999
        includes the impact of the Acquisition. On a pro forma basis, assuming
        the Acquisition had been consummated on October 1, 1996, the beginning
        of the prior-year periods discussed within, investment income would have
        been $517,606,000 and net income would have been $158,887,000 for the
        year ended September 30, 1998. For the year ended September 30, 1997,
        investment income would have been $506,399,000 and net income would have
        been $83,372,000.

        Included in the block of business acquired from MBL Life were policies
        whose owners are residents of New York State ("the New York Business").
        On July 1, 1999, the New York Business was acquired by the Company's New
        York affiliate, First SunAmerica Life Insurance Company ("FSA"), via an
        assumption reinsurance agreement, and the remainder of the business
        converted to assumption reinsurance in the Company, which superseded the
        coinsurance agreement. As part of this transfer, invested assets equal
        to $678,272,000, life reserves equal to $282,247,000, group pension
        reserves equal to $406,118,000, and other net assets of $10,093,000 were
        transferred to FSA.

        The $128,420,000 purchase price was allocated between the Company and
        FSA based on the estimated future gross profits of the two blocks of
        business. The portion allocated to FSA was $10,000,000.


        As part of the Acquisition, the Company received $242,473,000 from MBL
        to pay policy enhancements guaranteed by the MBL Life rehabilitation
        agreement to policyholders meeting certain requirements. A primary
        requirement was that annuity policyholders must have converted their MBL
        Life policy to a policy type currently offered by the Company or one of
        its affiliates by December 31, 1999. The enhancements are to be credited
        in four installments on January 1, 2000, June 30, 2001, June 30, 2002
        and June 30, 2003, to eligible policies still active on each of those
        dates. On December 31, 1999, the enhancement reserve for such payments
        totaled $223,032,000, which includes interest accredited at 6.75% on the
        original reserve. Of this amount, $69,836,000 was credited to
        policyholders in February 2000 for the January 1, 2000 installment.

        At December 31, 1999, mortgage loans were collateralized by properties
        located in 29 states, with loans totaling approximately 36% of the
        aggregate carrying value of the portfolio secured by properties located
        in California and approximately 11% by properties located in New York.
        No more than 8% of the portfolio was secured by properties in any other
        single state.

        At December 31, 1999, bonds, notes and redeemable preferred stocks
        included $377,149,000 of bonds and notes not rated investment grade. The
        Company had no material concentrations of non-investment-grade assets at
        December 31, 1999.

        At December 31, 1999, the carrying value of investments in default as to
        the payment of principal or interest was $1,529,000, composed of
        $870,000 of bonds and $659,000 of mortgage loans. Such nonperforming
        investments had an estimated fair value of $872,000.

        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 December 31, 1999, the Company
        had one outstanding Swap Agreement with a notional principal amount of
        $21,538,000, which matures in December 2024. The net interest paid
        amounted to $215,000 for the year ended December 31, 1999, $54,000 for
        the three months ended December 31, 1998, $278,000 for the year ended
        September 30, 1998, and $125,000 for the year ended September 30, 1997,
        and is included in Interest Expense on Guaranteed Investment Contracts
        in the income statement.

        At December 31, 1999, $7,418,000 of bonds, at amortized cost, were on
        deposit with regulatory authorities in accordance with statutory
        requirements.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

6.      FAIR VALUE OF FINANCIAL INSTRUMENTS (Continued)

        reasonable estimates of the fair value of only the Company's financial
        instruments. The disclosures do not address the value of the Company's
        recognized and unrecognized nonfinancial assets (including its real
        estate investments and other invested assets except for cost-method
        partnerships) and liabilities or the value of anticipated future
        business. The Company does not plan to sell most of its assets or settle
        most of its liabilities at these estimated fair values.

        The fair value of a financial instrument is the amount at which the
        instrument could be exchanged in a current transaction between willing
        parties, other than in a forced or liquidation sale. Selling expenses
        and potential taxes are not included. The 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.

        SEPARATE ACCOUNT SEED MONEY: Carrying value is the market value of the
        underlying securities.

        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 HELD IN SEPARATE ACCOUNTS: Variable annuity
        assets are carried at the market value of the underlying securities.

        RESERVES FOR FIXED ANNUITY CONTRACTS: Deferred annuity 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 UNIVERSAL LIFE INSURANCE CONTRACTS:  Universal  life  and

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

6.      FAIR VALUE OF FINANCIAL INSTRUMENTS (Continued)

        single life premium life contracts are assigned a fair value equal to
        current net surrender value.

        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 a hedging Swap Agreement, determined from
        independent broker quotes.

        RECEIVABLE FROM/PAYABLE TO BROKERS FOR PURCHASES OF SECURITIES: Such
        obligations represent transactions of a short-term nature for which the
        carrying value is considered a reasonable estimate of fair value.

        MODIFIED COINSURANCE DEPOSIT LIABILITY: Fair value is based on
        discounting the liability by the appropriate cost of funds, and
        therefore approximates carrying value.

        VARIABLE ANNUITY LIABILITIES RELATED TO SEPARATE ACCOUNTS: 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.

        SUBORDINATED NOTES PAYABLE TO AFFILIATES: Fair value is estimated based
        on the quoted market prices for similar issues.

7.      SUBORDINATED NOTES PAYABLE TO AFFILIATES

        At December 31, 1998, Subordinated Notes Payable to Affiliates included
        a surplus note (the "Note") payable to its immediate parent, SunAmerica
        Life Insurance Company (the "Parent"), for $170,436,000. On June 30,
        1999, the Parent cancelled the Note and forgave the interest earned.
        Funds received were reclassified to Additional Paid-in Capital in the
        accompanying consolidated balance sheet.

        Subordinated notes and accrued interest payable to affiliates totaled
        $37,816,000 at interest rates ranging from 8% to 9% at December 31,
        1999, and require principal payments of $5,400,000 in 2000, $10,000,000
        in 2001 and $22,060,000 in 2002.

8.      REINSURANCE

        The business which was assumed from MBL Life is subject to existing
        reinsurance ceded agreements. At December 31, 1998, the maximum
        retention on any single life was $2,000,000, and a total credit of
        $5,057,000 was taken against the life insurance reserves, representing
        predominantly yearly renewable term reinsurance. In order to limit even
        further the exposure to loss on any single insured and to recover an
        additional portion of the benefits paid over such limits, the Company
        entered into a reinsurance treaty effective January 1, 1999 under which
        the Company retains no more than $100,000 of risk on any

8.      REINSURANCE (Continued)

        one insured life. At December 31, 1999, a total reserve credit of
        $3,560,000 was taken against the life insurance reserves. With respect
        to these coinsurance agreements, the Company could become liable for all
        obligations of the reinsured policies if the reinsurers were to become
        unable to meet the obligations assumed under the respective reinsurance
        agreements. The Company monitors its credit exposure with respect to
        these agreements. However, due to the high credit ratings of the
        reinsurers, such risks are considered to be minimal.

        On August 1, 1999, the Company entered into a modified coinsurance
        transaction, approved by the Arizona Department of Insurance, which
        involved the ceding of approximately $6,000,000,000 of variable
        annuities to ANLIC Insurance Company (Hawaii), a non-affiliated stock
        life insurer. The transaction is accounted for as reinsurance for
        statutory reporting purposes. As part of the transaction, the Company
        received cash in the amount of $150,000,000 and recorded a corresponding
        deposit liability. As payments are made to the reinsurer, the deposit
        liability is relieved. The cost of this program, $3,621,000 in 1999, is
        classified as General and Administrative Expenses in the income
        statement.

        On August 11, 1998, the Company entered into a similar modified
        coinsurance transaction, approved by the Arizona Department of
        Insurance, which involved the ceding of approximately $6,000,000,000 of
        variable annuities to ANLIC Insurance Company (Cayman), a Cayman Islands
        stock life insurance company, effective December 31, 1997. As a part of
        this transaction, the Company received cash amounting to approximately
        $188,700,000, and recorded a corresponding reduction of DAC related to
        the coinsured annuities. As payments were made to the reinsurer, the
        reduction of DAC was relieved. Certain expenses related to this
        transaction were charged directly to DAC amortization in the income
        statement. The net effect of this transaction in the income statement
        was not material.

        On December 31, 1998, the Company recaptured this business. As part of
        this recapture, the Company paid cash of $170,436,000 and recorded an
        increase in DAC of $167,202,000 with the balance of $3,234,000 being
        recorded as DAC amortization in the income statement.

9.      CONTINGENT LIABILITIES

        The Company has entered into four agreements in which it has provided
        liquidity support for certain short-term securities of municipalities
        and non-profit organizations 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 $359,400,000. The Company's Parent currently shares in the
        liabilities and fees of two of these agreements. The Parent's share in
        these liabilities will increase by $150,000,000 subsequent to December
        31, 1999, and the Company's share will decrease to $209,400,000.
        Management does not anticipate any material future losses with respect
        to these liquidity support facilities.

9.      CONTINGENT LIABILITIES (Continued)

        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, results of operations or cash
        flows.

        The Company's current financial strength and counterparty credit ratings
        from Standard & Poor's are based in part on a guarantee (the
        "Guarantee") of the Company's insurance policy obligations by American
        Home Assurance Company ("American Home"), a subsidiary of AIG, and a
        member of an AIG intercompany pool, and the belief that the Company is
        viewed as a strategically important member of AIG. The Guarantee is
        unconditional and irrevocable, and policyholders have the right to
        enforce the Guarantee directly against American Home.

        The Company's current financial strength rating from Moody's is based in
        part on a support agreement between the Company and AIG (the "Support
        Agreement"), pursuant to which AIG has agreed that AIG will cause the
        Company to maintain a policyholder's surplus of not less than $1 million
        or such greater amount as shall be sufficient to enable the Company to
        perform its obligations under any policy issued by it. The Support
        Agreement also provides that if the Company needs funds not otherwise
        available to it to make timely payment of its obligations under policies
        issued by it, AIG will provide such funds at the request of the Company.
        The Support Agreement is not a direct or indirect guarantee by AIG to
        any person of any obligation of the Company. AIG may terminate the
        Support Agreement with respect to outstanding obligations of the Company
        only under circumstances where the Company attains, without the benefit
        of the Support Agreement, a financial strength rating equivalent to that
        held by the Company with the benefit of the support agreement.
        Policyholders have the right to cause the Company to enforce its rights
        against AIG and, if the Company fails or refuses to take timely action
        to enforce the Support Agreement or if the Company defaults in any claim
        or payment owed to such policyholder when due, have the right to enforce
        the Support Agreement directly against AIG.

        American Home does not publish financial statements, although it files
        statutory annual and quarterly reports with the New York State Insurance
        Department, where such reports are available to the public. AIG is a
        reporting company under the Securities Exchange Act of 1934, and
        publishes annual reports on Form 10-K and quarterly reports on Form
        10-Q, which are available from the Securities and Exchange Commission.

10.     SHAREHOLDER'S EQUITY (Continued)

        Dividends that the Company may pay to its shareholder in any year
        without prior approval of the Arizona Department of Insurance are
        limited by statute. The maximum amount of dividends which can be paid to
        shareholders of insurance companies domiciled in the state of Arizona
        without obtaining the prior approval of the Insurance Commissioner is
        limited to the lesser of either 10% of the preceding year's statutory
        surplus or the preceding year's statutory net gain from operations less
        equity in undistributed income or loss of subsidiaries included in net
        investment income if, after paying the dividend, the Company's capital
        and surplus would be adequate in the opinion of the Arizona Department
        of Insurance. No dividends were paid in the year ended December 31, 1999
        or the three months ended December 31, 1998. Dividends in the amounts of
        $51,200,000 and $25,500,000 were paid on June 4, 1998 and April 1, 1997,
        respectively. Dividends of $69,000,000 were paid on March 1, 2000.

        Under statutory accounting principles utilized in filings with insurance
        regulatory authorities, the Company's net income for the year ended
        December 31, 1999 was $261,539,000. The statutory net loss for the year
        ended December 31, 1998 was $98,766,000. The statutory net income for
        the year ended December 31, 1997 totaled $74,407,000. The Company's
        statutory capital and surplus totaled $694,621,000 at December 31, 1999,
        $443,394,000 at December 31, 1998 and $537,542,000 at September 30,
        1998.

        On June 30, 1999, the Parent cancelled the Company's surplus note
        payable of $170,436,000 and funds received were reclassified to
        Additional Paid-in Capital in the accompanying consolidated balance
        sheet. On September 9, 1999, the Company paid $170,500,000 to its Parent
        as a return of capital. On September 14, 1999 and October 25, 1999, the
        Parent contributed additional capital to the Company in the amounts of
        $54,250,000 and $60,000,000, respectively. Also on December 31, 1999,
        the Parent made a $150,000 contribution of partnership investments.

        For United States federal income tax purposes, certain amounts from life
        insurance operations are accumulated in a memorandum policyholders'
        surplus account and are taxed only when distributed to shareholders or
        when such account exceeds prescribed limits. The accumulated
        policyholders' surplus was $14,300,000 at December 31, 1999. The Company
        does not anticipate any transactions which would cause any part of this
        surplus to be taxable.

12.     COMPREHENSIVE INCOME


        Effective October 1, 1998, the Company adopted Statement of Financial
        Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
        130") which requires the reporting of comprehensive income in addition
        to net income from operations. Comprehensive income is a more inclusive
        financial reporting methodology that includes disclosure of certain
        financial information that historically has not been recognized in the
        calculation of net income. The adoption of SFAS 130 did not have an
        impact on the Company's results of operations, financial condition or
        liquidity. Comprehensive income amounts for the prior years are
        disclosed to conform to the current year's presentation.

13.     RELATED-PARTY MATTERS

        The Company pays commissions to five affiliated companies: SunAmerica
        Securities, Inc.; Advantage Capital Corp.; Financial Services Corp.;
        Sentra Securities Corp.; and Spelman & Co. Inc. Commissions paid to
        these broker-dealers totaled $37,435,000 in the year ended December 31,
        1999, $6,977,000 in the three months ended December 31, 1998, and
        $32,946,000 in the year ended September 30, 1998 and $25,492,000 in the
        year ended September 30, 1997. These broker-dealers, when combined with
        the Company's wholly owned broker-dealer, represent a significant
        portion of the Company's business, amounting to approximately 35.6% of
        premiums in the year ended December 31, 1999 and the three months ended
        December 31, 1998, 33.6% in the year ended September 30, 1998 and 36.1%
        in the year ended September 30, 1997.

        The Company purchases administrative, investment management, accounting,
        marketing and data processing services from its Parent and SunAmerica,
        an indirect parent. Amounts paid for such services totaled $105,059,000
        for the year ended December 31, 1999, $21,593,000 for the three months
        ended December 31, 1998, $84,975,000 for the year ended September 30,
        1998 and $86,116,000 for the year ended September 30, 1997. The
        marketing component of such costs during these periods amounted to
        $53,385,000, $9,906,000, $39,482,000 and $31,968,000, respectively, and
        are deferred and amortized as part of Deferred Acquisition Costs. The
        other components of such costs are included in General and
        Administrative Expenses in the income statement.

        At December 31, 1999 and 1998, the Company held bonds with a fair value
        of $50,000 and $84,965,000, respectively, which were issued by its
        affiliate, International Lease Finance Corp. The amortized cost of these
        bonds is equal to the fair value. At September 30, 1998 and 1997, the
        Company held no investments issued by any of its affiliates.

        During the year ended December 31, 1999, the Company transferred
        short-term investments and bonds to FSA with an aggregate fair value of
        $634,596,000 as part of the transfer of the New York Business from the
        Acquisition (See Note 4). The Company recorded a net realized loss of
        $5,144,000 on the transfer of these assets.

        During the year ended December 31, 1999, the Company purchased certain
        invested assets from SunAmerica for cash equal to their current market
        value of $161,159,000.

        For the three months ended December 31, 1998, the Company made no
        purchases or sales of invested assets from or to the Parent or its
        affiliates.

        During the year ended September 30, 1998, the Company sold various
        invested assets to SunAmerica for cash equal to their current market
        value of $64,431,000. The Company recorded a net gain aggregating
        $16,388,000 on such transactions.

        During the year ended September 30, 1998, the Company purchased certain
        invested assets from SunAmerica, the Parent and CalAmerica Life
        Insurance Company ("CalAmerica"), a wholly-owned subsidiary of the
        Parent that has since merged into the Parent, for cash equal to their
        current market value which aggregated $20,666,000, $10,468,000

        invested assets to the Parent and CalAmerica for cash equal to their
        current market value of $15,776,000 and $15,000, respectively. The
        Company recorded a net gain aggregating $276,000 on such transactions.

        During the year ended September 30, 1997, the Company purchased certain
        invested assets from the Parent and CalAmerica for cash equal to their
        current market value of $8,717,000 and $284,000, respectively.

14.     BUSINESS SEGMENTS

        Effective January 1, 1999, the Company adopted Statement of Financial
        Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments
        of an Enterprise and Related Information," which requires the reporting
        of certain financial information by business segment. For the purpose of
        providing segment information, the Company has three business segments:
        annuity operations, asset management operations and broker-dealer
        operations. The annuity operations focus primarily on the marketing of
        variable annuity products and the administration of the universal life
        business acquired from MBL Life in 1998 (See Note 4). The Company's
        variable annuity products offer investors a broad spectrum of fund
        alternatives, with a choice of investment managers, as well as
        guaranteed fixed-rate account options. The Company earns fee income on
        investments in the variable options and net investment income on the
        fixed-rate options. The asset management operations are conducted by the
        Company's registered investment advisor subsidiary, SunAmerica Asset
        Management Corp. ("SunAmerica Asset Management"), and its related
        distributor. SunAmerica Asset Management earns fee income by
        distributing and managing a diversified family of mutual funds, by
        managing certain subaccounts within the Company's variable annuity
        products and by providing professional management of individual,
        corporate and pension plan portfolios. The broker-dealer operations are
        conducted by the Company's broker-dealer subsidiary, Royal Alliance
        Associates, Inc. ("Royal"), which sells proprietary annuities and mutual
        funds, as well as a full range of non-proprietary investment products.

        Substantially all of the Company's revenues are derived from the United
        States.

        The accounting policies of the segments are as described in the summary
        of significant accounting policies (Note 2). The Parent makes
        expenditures for long-lived assets for the annuity operations segment
        and allocates depreciation of such assets to the annuity operations
        segment. The annuity operations and asset management operations pay
        commissions to Royal for sales of their proprietary products.
        Approximately 90% of these commission payments are in turn paid to
        registered representatives of Royal, with the remainder of the revenue
        reflected in Net Retained Commissions. In addition, premiums from
        variable annuity policies sold by the Company are held in trusts that
        are owned by the Company, although the assets directly support
        policyholder obligations. SunAmerica Asset Management is the Investment
        Advisor for all of the subaccounts of these trusts, for which service it
        receives fees which are direct expenses of the trusts. Such fees are
        reported as Variable Annuity Fees in the consolidated income statement
        and are shown as intersegment revenues in the business segments

                        REPORT OF INDEPENDENT ACCOUNTANTS


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 the Variable Account constituting Variable Separate Account (Portion
Relating to the POLARIS Variable Annuity), a separate account of Anchor National
Life Insurance Company (the "Separate Account") at December 31, 1999 and
November 30, 1999, the results of their operations for the one month ended
December 31, 1999 and for the fiscal year ended November 30, 1999, and the
changes in their net assets for the one month ended December 31, 1999 and for
the two fiscal years ended November 30, 1999 and 1998, in conformity with
accounting principles generally accepted in the United States. 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 auditing standards generally accepted in the United States 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 December 31, 1999 and November 30, 1999 by correspondence
with the custodian, provide a reasonable basis for the opinion expressed above.

                          NOTES TO FINANCIAL STATEMENTS


1.          ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

            Variable Separate Account (Portion Relating to the POLARIS Variable
            Annuity) of Anchor National Life Insurance Company (the "Separate
            Account") is a segregated investment account of Anchor National Life
            Insurance Company (the "Company"). The Company is an indirect,
            wholly owned subsidiary of American International Group, Inc.
            ("AIG"), an international insurance and financial services company.
            At December 31, 1998, the company was a wholly owned indirect
            subsidiary of SunAmerica Inc., a Maryland corporation. On January 1,
            1999, SunAmerica Inc. merged with and into AIG in a tax-free
            reorganization that has been treated as a pooling of interests and
            accounting purposes. Thus, SunAmerica Inc. ceased to exist on that
            date. However, immediately prior to the effectiveness of the merger,
            substantially all of the net assets of SunAmerica Inc. were
            contributed to a newly formed subsidiary of AIG named SunAmerica
            Holdings, Inc., a Delaware corporation. SunAmerica Holdings, Inc.
            subsequently changed its name to SunAmerica Inc. The Separate
            Account is registered as a segregated unit investment trust pursuant
            to the provisions of the Investment Company Act of 1940, as amended.

            The Separate Account is composed of twenty-seven variable portfolios
            (the "Variable Accounts"). Each of the Variable Accounts is invested
            solely in the shares of either (1) one of the four currently
            available investment portfolios of Anchor Series Trust ("Anchor
            Trust") or (2) one of the twenty-three currently available
            investment portfolios of SunAmerica Series Trust ("SunAmerica
            Trust"). The Anchor Trust and the SunAmerica Trust (the "Trusts")
            are each diversified, open-end, affiliated investment companies,
            which retain investment advisors to assist in the investment
            activities of the Trusts. The participant may elect to have payments
            allocated to any of five guaranteed-interest funds of the Company
            (the "General Account"), which are not a part of the Separate
            Account. The financial statements include balances allocated by the
            participant to the twenty-seven Variable Accounts and do not include
            balances allocated to the General Account.

            1999. The inception date of the "Dogs" of Wall Street Portfolio was

            ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
            (continued)

            The investment objectives and policies of the four portfolios of the
            Anchor Trust are summarized below:

            The CAPITAL APPRECIATION PORTFOLIO seeks long-term capital
            appreciation. This portfolio invests in growth equity securities
            which are widely diversified by industry and company using a
            wide-ranging and flexible stock picking approach; may be
            concentrated and will generally have less investments in large
            company securities than the Growth Portfolio.

            The GROWTH PORTFOLIO seeks capital appreciation. This portfolio
            invests in core equity securities that are widely diversified by
            industry and company.

            The NATURAL RESOURCES PORTFOLIO seeks a total return in excess of
            the U.S. rate of inflation as represented by the Consumer Price
            Index. This portfolio invests primarily in equity securities of U.S.
            or foreign companies that are expected to provide favorable returns
            in periods of rising inflation.

            The GOVERNMENT AND QUALITY BOND PORTFOLIO seeks relatively high
            current income, liquidity and security of principal. This portfolio
            invests in obligations issued, guaranteed or insured by the U.S.
            Government, its agencies or instrumentalities and in high quality
            corporate fixed securities.

            Anchor Trust has portfolios in addition to those identified above;
            however, none of these other portfolios is currently available for
            investment under the Separate Account.

            The investment objectives and policies of the twenty-three
            portfolios of the SunAmerica Trust are summarized below:

            The INTERNATIONAL DIVERSIFIED EQUITIES PORTFOLIO seeks long-term
            capital appreciation. This portfolio invests (in accordance with
            country weightings as determined by the Subadviser) in common stocks
            of foreign issuers which, in the aggregate, replicate broad country
            and sector indices.

            The GLOBAL EQUITIES PORTFOLIO seeks long-term growth of capital.
            This portfolio invests primarily in common stocks or securities of
            U.S. and foreign issuers with common stock characteristics which
            demonstrate the potential for appreciation and engages in
            transactions in foreign currencies.

            (continued)

            The AGGRESSIVE GROWTH PORTFOLIO seeks capital appreciation. This
            portfolio invests primarily in equity securities of high growth
            companies including small companies with market capitalizations
            under $1 billion.

            The VENTURE VALUE PORTFOLIO seeks growth of capital. This portfolio

            above-average growth prospects.

            The MFS GROWTH AND INCOME PORTFOLIO (PREVIOUSLY KNOWN AS
            GROWTH/PHOENIX INVESTMENT COUNSEL PORTFOLIO) seeks reasonable
            current income and long-term growth of capital and income. This
            portfolio invests primarily in equity securities.

            The ALLIANCE GROWTH PORTFOLIO seeks long term growth of capital.
            This portfolio invests primarily in common stocks or securities of a
            limited number of large, carefully selected, high quality U.S.
            companies that are judged likely to achieve superior earnings.

            The GROWTH-INCOME PORTFOLIO seeks growth of capital and income. This
            portfolio invests primarily in common stocks or securities which
            demonstrate the potential for appreciation and/or dividends.

            The ASSET ALLOCATION PORTFOLIO seeks high total return (including
            income and capital gains) consistent with preservation of capital
            over the long term. This portfolio invests in a diversified
            selection of common stocks and other securities having common stock
            characteristics, bonds and other intermediate and long-term

            The MFS TOTAL RETURN PORTFOLIO (PREVIOUSLY KNOWN AS BALANCED/PHOENIX
            INVESTMENT COUNSEL PORTFOLIO) seeks reasonable income, long-term
            capital growth and conservation of capital. This portfolio invests
            primarily in common stocks and fixed-income securities, with an
            emphasis on income-producing securities which appear to have some
            potential for capital enhancement.

            The UTILITY PORTFOLIO seeks high current income and moderate capital
            appreciation. This portfolio invests primarily in the equity and
            debt securities of utility companies.

            The WORLDWIDE HIGH INCOME PORTFOLIO seeks high current income and,
            secondarily, capital appreciation. This portfolio invests primarily
            in a selection of high-yielding fixed-income securities of issuers
            located throughout the world.

            The HIGH-YIELD BOND PORTFOLIO seeks a high level of current income
            and, secondarily, capital appreciation. This portfolio invests
            primarily in intermediate and long-term corporate obligations, with
            emphasis on higher-yielding, higher-risk, lower-rated or unrated
            securities with a primary focus on "B" rated high-yield bonds.

            The GLOBAL BOND PORTFOLIO seeks a high total return, emphasizing
            current income and, to a lesser extent, providing opportunities for
            capital appreciation. This portfolio invests in high quality
            fixed-income securities of U.S. and foreign issuers and engages in
            transactions in foreign currencies.

            The CORPORATE BOND PORTFOLIO seeks a high total return with only
            moderate price risk. This portfolio invests primarily in investment
            grade fixed-income securities.

            The INTERNATIONAL GROWTH AND INCOME PORTFOLIO seeks growth of
            capital with current income as a secondary objective. This portfolio
            invests primarily in common stocks traded on markets outside the
            United States.

            The EMERGING MARKETS PORTFOLIO seeks long-term capital appreciation.
            This portfolio invests mainly in the common stocks and other equity
            securities of companies that its Subadviser believes have
            above-average growth prospects primarily in emerging markets outside
            the United States.

            ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
            (continued)

            The REAL ESTATE PORTFOLIO seeks to achieve total return through a
            combination of growth and income. This portfolio invests primarily
            in securities of companies principally engaged in or related to the
            real estate industry or which own significant real estate assets or
            which primarily invest in real estate financial instruments.

            The "DOGS" OF WALL STREET PORTFOLIO seeks total return (including
            capital appreciation and current income) primarily through the
            annual selection of thirty high dividend yielding common stocks from
            the Dow Jones Industrial Average and the broader market.

            The MFS MID-CAP GROWTH PORTFOLIO seeks long-term growth of capital.
            This portfolio invests primarily in equity securities of
            medium-sized companies, generally with market capitalizations
            between $1 billion and $5 billion, that its Subadvisor believes have
            above-average growth potential.

            The CASH MANAGEMENT PORTFOLIO seeks high current yield while
            preserving capital. This portfolio invests in a diversified
            selection of money market instruments.

            The SunAmerica Trust has portfolios in addition to those identified
            above; however, none of these other portfolios is currently
            available for investment under the Separate Account.

            Purchases and sales of shares of the portfolios of the Trusts are
            valued at the net asset values of the shares on the date the shares
            are purchased or sold. Dividends and capital gains distributions are
            recorded when received. Realized gains and losses on the sale of
            investments in the Trusts are recognized at the date of sale and are
            determined on an average cost basis.

            Accumulation unit values are computed daily based on the total net
            assets of the Variable Accounts.

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:

            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 RISK, GUARANTEE DEATH BENEFIT AND EXPENSE RISK CHARGE: The
            Company deducts mortality risk, guarantee death benefit 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 (0.90%) 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. The guarantee death benefit and expense risk
            charges (0.12% and 0.35%, respectively) are compensation for
            providing 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.
