                                SEPARATE ACCOUNT


        Variable Separate Account was originally established by 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
funds 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


<PAGE>   9

allocated to the separate account or any other segregated asset account of the
Company. A Purchase Payment may be allocated to the 1, 3, 5, 7 or 10 year fixed
account options and the DCA accounts for 6-month and 1-year periods available in
connection with the general account, as elected by the owner at the time of
purchasing a contract or when making a subsequent Purchase Payment. Assets
supporting amounts allocated to fixed account options become part of the
Company's general account assets and are available to fund the claims of all
classes of customers of the Company, as well as of its creditors. Accordingly,
all of the Company's assets held in the general account will be available to
fund the Company's obligations under the contracts as well as such other claims.

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


                                PERFORMANCE DATA


        From time to time the separate account may advertise the Cash Management
Portfolio's "yield" and "effective yield." Both yield figures are based on
historical earnings and are not intended to indicate future performance. The
"yield" of the Cash Management Portfolio refers to the net income generated for
a contract funded by an investment in the Cash Management Portfolio (which
invests in shares of the Cash Management Portfolio of SunAmerica Series 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 (including the mortality and expense risk charge,
distribution expense charge and contract maintenance fee) 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.


        For periods starting prior to the date the Variable Portfolios first
became available through the Separate Account, the total return data for the
Variable Portfolios of the Separate Account will be derived from the performance
of the



<PAGE>   10

corresponding underlying funds of Anchor Series Trust and SunAmerica 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 and SunAmerica Series Trust underlying fund. In
some cases a particular Variable Portfolio may have been available in another
contract funded through this separate account. If the Variable Portfolio was
incepted in this separate account prior to the offering of this contract, we
report standardized contract performance adjusted for the fees and charges on
this contract. Performance figures similarly adjusted but based on underlying
SunAmerica Series Trust or Anchor Series Trust performance (outside of this
separate account) should not be construed to be actual historical performance of
the relevant separate account Variable Portfolio. Rather, they are intended to
indicate the historical performance of the corresponding underlying funds of
Anchor Series Trust and SunAmerica Series Trust, adjusted to provide direct
comparability to the performance of the Variable Portfolios after the date the
contracts were first offered to the public (which will reflect the effect of
fees and charges imposed under the contracts). Anchor Series Trust and
SunAmerica 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


        For contracts without the Principal Rewards Program, the annualized
current yield and the effective yield for the Cash Management Portfolio for the
7 day period ending December 31, 1999 were 4.57% and 4.68%, respectively. For
contracts with the Principal Rewards Program, the annualized current yield and
the effective yield for the Cash Management Portfolio for the 7 day period
ending December 31, 1999 were 6.57% and 6.79%, 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:

               For contracts without the Principal Rewards Program:

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


               For contracts with the Principal Rewards Program:

                      Base Period Return = (EV-SV-CMF+E)/(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


<PAGE>   11

                E =   Premium Enhancement Rate, 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 charge is proportional to the percentage of the number of
contract owners' accounts that have money allocated to that Variable Portfolio.
The portion of the charge allocable to the Cash Management Portfolio 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, the
result is multiplied by the fraction 7/365 to arrive at the portion attributable
to the 7 day period.

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

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

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

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

        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 on the type, quality and maturities of the investments
held by the underlying fund and changes in interest rates on such investments.

        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 since each Variable Portfolio's inception date, for a
1-year period and, if applicable, for a 5-year period, are shown on the
following two pages, both with and without an assumed complete redemption at the
end of the stated period. Total returns for contracts without the Principal
Rewards Program are on page 8 and total returns for contracts with the Principal
Rewards Program are on page 9.


<PAGE>   12

        Standardized performance for the Variable Portfolios available in this
contract reflect total returns using the method of computation discussed below:

- -   Using the seven year surrender charge schedule available on contracts issued
without the Principal Rewards Program. No enhancement is reflected under the
calculation, as the Payment Enhancement is not available unless the Principal
Rewards Program is elected; AND

- -   Using the nine year surrender charge schedule available on contracts issued
with the Principal Rewards Program, including the minimum Initial Payment
Enhancement of 2% of Purchase Payments and calculating the value after
redemption only based on the initial $1,000 Purchase Payment.

- -   We may, from time to time, advertise other variations of performance along
with the standardized performance as described above. We may, in sales
literature, show performance only applicable to one surrender charge schedule to
a contract holder who has already purchased the contract with or without the
Principal Rewards Program.

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 a specified time
period (one, five, and ten years, or since inception) 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:

        For contracts without the Principal Rewards Program:

                     n
               P(1+T)  = ERV

        For contracts with the Principal Rewards Program:

                            n
               [P(1+E)](1+T)  = ERV

where:         P =    a hypothetical initial payment of $1,000
               T =    average annual total return
               n =    number of years
               E =    Payment Enhancement Rate
             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 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. 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 account options 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, and the annuity option selected.

        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


<PAGE>   16

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.



INCOME PAYMENTS UNDER THE INCOME PROTECTOR FEATURE

        If contract holders elect to begin Income Payments using the Income
Protector feature, the income benefit base is determined as described in the
prospectus. The initial Income Payment is determined by applying the income
benefit base to the annuity table specifically designated for use in conjunction
with the Income Protector feature, either in the contract or in the endorsement
to the contract. Those tables are based on a set amount per $1,000 of income
benefit base 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, and the Income Option
selected.

        The income benefit base is applied 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. The amount of the second and
each subsequent income payment is the same as that determined above for the
first monthly payment.

                               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 exceeds 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


<PAGE>   17

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 in no change; a NIF
greater than 1.000 results in an increase; and a NIF less than 1.000 results in
a decrease. 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 the
previous month. The NIF for the month of September is:

                      NIF = ($11.46/$11.44)

                             = 1.00174825

        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


<PAGE>   18

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.

        P's first variable Income Payment is determined from the annuity factor
tables in P's contract, using the information assumed above. From these tables,
which supply monthly annuity factors for each $1,000 of applied contract value,
P's first variable Income Payment is determined by multiplying the factor of
$4.92 (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 = $4.92 x ($116,412.31/$1,000) = $572.75

        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 = $572.75/$13.256932 = 43.203812

        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:


<PAGE>   19

             Second Payment = 43.203812 x $13.327695 = $575.81

        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 Annuity Phase
(assuming no transfers from the Variable Portfolio). The net investment
performance of the Variable Portfolio during the Annuity 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 Nonqualified 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 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.


<PAGE>   20

        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
any payments under the contract. The Code contains a safe harbor provision which
provides that annuity contracts, such as your contract, meet the diversification
requirements if, as of the close of each calendar quarter, the underlying assets
meet the diversification standards for a regulated investment company, and no
more than 55% of the total assets consist of cash, cash items, U.S. government
securities and securities of other regulated investment companies.

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

MULTIPLE CONTRACTS

        Multiple annuity contracts which are issued within a calendar year to
the same contract owner by one company or its affiliates are treated as one
annuity contract for purposes of determining the tax


<PAGE>   21

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.

QUALIFIED PLANS

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

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

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

        (a)    H.R. 10 PLANS

               Section 401 of the Code permits self-employed individuals to
        establish Qualified plans for themselves and their employees, commonly
        referred to as "H.R. 10" or "Keogh" Plans. Contributions made to the
        plan for the benefit of the employees will not be included in the gross
        income of the employees until distributed from the plan. The tax
        consequences to owners may vary depending upon the particular plan
        design. However, the Code places limitations and restrictions on all
        plans on 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. Purchasers of
        contracts for use with an H.R. 10 Plan should obtain competent tax
        advice as to the tax treatment and suitability of such an investment.

        (b)    TAX-SHELTERED ANNUITIES

               Section 403(b) of the Code permits the purchase of "tax-sheltered
        annuities" by public


<PAGE>   22

        schools and certain charitable, education 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. Any
        employee should obtain competent tax advice as to the tax treatment and
        suitability of such an investment.

        (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. Purchasers
        of contracts to be qualified as IRAs should obtain competent tax advice
        as to the tax treatment and suitability of such an investment.


        (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 the 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

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


<PAGE>   23

        (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.

Variable Separate Account (Portion Relating to the POLARIS II 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 II 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 November 30, 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 II
           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 for 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 seven guaranteed-interest funds of the Company (the "General
           Account"), which are not a part of the Separate Account. If no
           election is made, the payments will be invested according to the
           contracholder's last allocation instructions. 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.

           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:

           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.

           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.

           INCOME PROTECTOR FEATURE: The Income Protector Feature is a "safety
           net" which offers the ability to receive a guaranteed fixed minimum
           retirement income during the Income Phase. The Income Protector is a
           standard feature of your contract at no additional charge. Other
           options were previously available under the Income Protector feature.
           Generally, if the contract was purchased between November 2, 1998 and
           March 31, 1999 the other provisions continue to apply to the
           contract. The minimum guaranteed income is determined upon
           calculation of the "income benefit base." The "income benefit base"
           calculation is equal to the contract's value on the election date,
           plus all subsequent purchase payments, less all withdrawals and
           applicable fees and charges in an amount proportionate to the amount
           by which such withdrawals decrease the contract's value.

           PRINCIPAL REWARDS PROGRAM: The Principal Rewards Program adds an
           amount to the contract (an "Initial Payment Enhancement") each time a
           Purchase Payment is submitted. The Initial Payment Enhancement is
           calculated as 2.00% of each Purchase Payment. Additionally, an amount
           may be added to the contract at a future date (a "Deferred Payment
           Enhancement"). For Purchase Payments received by March 31, 2000, the
           Current Deferred Payment Enhancement Percentage is 2.00%. After March
           31, 2000, the Current Deferred Payment Enhancement Percentage may be
           increased, decreased, or eliminated. Purchase Payments may not be
           invested in a 6-month or 1 year Dollar Cost Averaging fixed accounts
           if participating in the Principal Rewards Program.

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 and also vary
           according to participation in the Principal Rewards Program. 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.

           CONTRACT MAINTENANCE FEE: An annual contract maintenance fee of $35
           ($30 in North Dakota) 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.

          CHARGES AND DEDUCTIONS (continued)

          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.
