                                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>   9


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-
<PAGE>   10

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>   11


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>   13


                  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>   14


                               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>   15

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>   16


         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>   17

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>   18


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.

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-

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>   20


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
Capital Services, Inc., located at 733 Third Avenue, 4th Floor, New York, New
York 10017. SunAmerica Capital Services, Inc. is registered as a broker-dealer

                        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.

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.

            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.

            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.
