                                    SUMMARY
- --------------------------------------------------------------------------------
 
   
     This summary sets forth some of the more important points that you should
know and consider before purchasing the ICAP II Variable Annuity. The remainder
of the prospectus discusses the topics in more detail. We urge you to read it
carefully and retain it, and the prospectus for the Trust attached hereto, for
future reference.
    
 
WHAT IS AN ANNUITY CONTRACT?
 
     An annuity is a contract between you and an insurance company. You are the
owner of the contract. The contract provides three main benefits:
 
     - Tax Deferral: This means that you do not pay taxes on your earnings from
       the annuity until you withdraw them.
 
     - Death Benefit: If you die during the Accumulation Phase, the insurance
       company pays a death benefit to your Beneficiary.
 
     - Guaranteed Income: If elected, you receive a stream of income for your
       lifetime, or another available period you select.
 
   
     The ICAP II Variable Annuity is a contract between you and Anchor National
Life Insurance Company (Anchor National, the Company, Us, We). It is designed to
help you invest on a tax deferred basis and meet long-term financial goals, such
as retirement funding.
    
 
   
     Like most annuities, this contract has an Accumulation Phase and an Income
Phase. During the Accumulation Phase, you invest money in your contract. Your
earnings are based on the investment performance of the Variable Portfolios you
allocate money to and/or the interest rate earned on the fixed account option.
During the Income Phase, you will receive income payments from your annuity.
Depending on the option you choose, your payments may be fixed in dollar amount,
may vary with investment performance of the Variable Portfolios or be a
combination of both. Among other factors, the amount of money you are able to
accumulate in your contract during the Accumulation Phase will determine the
amount of your payments during the Income Phase.
    
 
WHAT IS THE DIFFERENCE BETWEEN A VARIABLE ANNUITY AND A FIXED ANNUITY?
 
     A fixed annuity earns interest at a fixed rate guaranteed by the insurance
company. A variable annuity typically provides a fixed account option but also
provides Variable Portfolios. The Variable Portfolios are similar to a mutual
fund, but are only available through the purchase of an annuity. Most
significantly, you as the contract owner bear the entire investment risk with
respect to any Purchase Payments allocated to the Variable Portfolios of an
annuity. This means that the value of your contract will go up and down,
depending on the performance of the Variable Portfolios.
 
     The ICAP II Variable Annuity is a variable annuity with one fixed account
option and eleven Variable Portfolios.
 
WHAT ARE THE INVESTMENT OPTIONS AVAILABLE UNDER THE CONTRACT?
 
     You may allocate money to the following Variable Portfolios of the Trust:

     You may also allocate money to the fixed account option for a period of one
year. We call this time period the guarantee period. Anchor National guarantees
the interest rate credited to money in the fixed account option. The interest
rate offered for the guarantee period may differ from time to time, but we will
never credit less than a 4% annual effective rate.
 
     During the Accumulation Phase, you may transfer among the Variable
Portfolios and/or the fixed account option. Fifteen free transfers are permitted
per contract year. After that, we assess a transfer fee.
 
HOW MAY I ACCESS MY MONEY?
 
   
     During the Accumulation Phase, you may withdraw money from your contract at
any time. After your first contract year, the first withdrawal you take each
contract year will be free of a withdrawal charge if it does not exceed the
greater of 10% of your total Purchase Payments still subject to a withdrawal
charge, less prior withdrawals or Purchase Payments out of penalty minus prior
withdrawals.
    
 
     Withdrawals in excess of these limits may be assessed a withdrawal charge.
Generally, withdrawals may be made from your contract in the amount of $500 or
more. You may request withdrawals in writing or by establishing systematic
withdrawals. Under systematic withdrawals, the minimum withdrawal amount is
$250.
 
     There are no withdrawal charges on that portion of your money invested for
five years or more. Of course, upon a withdrawal you may have to pay income tax.
A 10% IRS penalty tax may also apply if you are under age 59 1/2. Additionally,
we do not assess withdrawal charges upon payment of a death benefit.
 
CAN I EXAMINE THE CONTRACT?
 
     You may cancel your contract within ten days of your receipt of the
contract (or longer if required by state law) by mailing it to our Annuity
Service Center. Your contract will be treated as void on the date we receive it
and we will refund an amount equal to the contract value (unless otherwise
required by state law). Its value may be more or less than the money you
initially invested.
 
WHAT ARE THE CHARGES AND DEDUCTIONS UNDER A CONTRACT?
 
   
     Each year, we deduct a $30 contract maintenance fee from your contract. We
also deduct insurance charges which equal 1.40% annually of the average daily
value of your contract allocated to the Variable Portfolios. The insurance
charges include: mortality and expense risk, 1.25%, and distribution expense,
 .15%.
    
 
     As with other professionally managed investments, there are also investment
charges imposed on contracts with money allocated to the Variable Portfolios,
which are estimated to range from .58% to 1.48%.
 
     If you take money out in excess of the free withdrawal amount allowed for
in your contract, you may be assessed a withdrawal charge which is a percentage
of the Purchase Payments you withdraw. The percentage declines with each year
the money is in the contract as follows:

     Each year, you are allowed to make 15 transfers without charge. After your
first 15 free transfers, a $25 transfer fee ($10 in Pennsylvania and Texas) will
apply to each subsequent transfer.
 
     In a limited number of states, you may also be assessed a state premium tax
of up to 3.5% depending upon the state.

WHAT IS THE DEATH BENEFIT UNDER THE CONTRACT?
 
     If you die during the Accumulation Phase of your contract, your Beneficiary
will receive a death benefit.
 
     The death benefit is the greater of:
 
     1. the value of your contract at the time we receive satisfactory proof of
        death; or
 
     2. total Purchase Payments less any withdrawals and partial annuitizations
        (and any fees or charges applicable to such distributions), compounded
        at a 5% annual growth rate; or
 
     3. after your fifth contract year, your contract value on the last contract
        anniversary plus any Purchase Payments and less any withdrawals and
        partial annuitizations (and any fees or charges applicable to such
        distributions) since that contract anniversary.
 
WHAT ARE THE AVAILABLE INCOME OPTIONS UNDER THE CONTRACT?
 
     You can select from one of three income options:
 
       (1) payments for your lifetime, but for not less than 10 or 20 years;
 
       (2) payments for your lifetime and your survivor's lifetime;
 
       (3) payments for a specified period of 5 to 30 years.
 
     You will also need to decide when your income payments begin and if you
want your income payments to fluctuate with investment performance or remain
constant. Once you begin receiving income payments, you cannot change your
income option.
 
     If your contract is part of a Non-qualified retirement plan (one that is
established with after-tax dollars), payments during the Income Phase are
considered partly a return of your original investment. The "original
investment" part of each payment is not taxable as income. For contracts which
are part of a Qualified retirement plan using before-tax dollars, the entire
payment is taxable as income.

EXPLANATION OF FEE TABLES AND EXAMPLES
 
1. The purpose of the fee tables is to show you the various expenses you would
   incur directly and indirectly by investing in the contract. The table
   reflects expenses of the separate account as well as the Trust. The examples
   do not illustrate the tax consequences of surrendering the contract.
 
2. The examples assume that no transfer fees were imposed. Although premium
   taxes may apply in certain states, they are not reflected in the examples.
 
3. For purposes of the amounts reported in the examples, the contract
   maintenance fee is calculated by dividing the total amount of contract
   maintenance fees anticipated to be collected during the year by the total net
   assets of the separate account's divisions and the related fixed accounts
   assets.
 
4. THESE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
   EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

                                PERFORMANCE DATA
- --------------------------------------------------------------------------------
 
     We advertise the Money Market Portfolio's "yield" and "effective yield."
Both figures are based on historical earnings and are not intended to indicate
future performance. The "yield" of the Money Market Portfolio refers to the net
income generated for a contract funded by an investment in the Money Market
Portfolio over a seven-day period. This income is then "annualized." That is,
the
 
                                        9
<PAGE>   13
 
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 Money Market 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 Money
Market 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.
 
     The separate account may also advertise an annualized 30-day (or one month)
yield figure for Variable Portfolios other than the Money Market Portfolio.
These yield figures are based upon the actual performance of the Variable
Portfolio over a 30-day (or one month) period ending on a date specified in the
advertisement. Like the total return data described above, the 30-day (or one
month) yield data will reflect the effect of all recurring contract charges (but
will not reflect any withdrawal charges or premium taxes). The yield figure is
derived from net investment gain (or loss) over the period expressed as a
fraction of the investment's value at the end of the period.
 
     More detailed information on the computation of advertised performance data
for the separate account is contained in the SAI.

              DESCRIPTION OF ANCHOR NATIONAL, THE SEPARATE ACCOUNT
                            AND THE GENERAL ACCOUNT
- --------------------------------------------------------------------------------
 
ANCHOR NATIONAL LIFE INSURANCE COMPANY
 
     Anchor National is a stock life insurance company organized under the laws
of the state of Arizona. Its principal place of business is 1 SunAmerica Center,
Los Angeles, California 90067-6022. We conduct life insurance and annuity
business in the District of Columbia and all states except New York. We are an
indirect wholly-owned subsidiary of American International Group, Inc. ("AIG"),
a Delaware corporation.
 
     Anchor National and its affiliates, SunAmerica Life Insurance Company,
First SunAmerica Life Insurance Company, CalAmerica Life Insurance Company,
SunAmerica National Life Insurance Company, SunAmerica Asset Management Corp.,
Resources Trust Company and six broker-dealers, specialize in retirement savings
and investment products and services. Business focuses include fixed and
variable annuities, mutual funds, premium finance, broker-dealer services and
trust administration services.
 
     Anchor National may advertise the rating and other information assigned to
it by independent industry ratings organizations. Some of those organizations
are A.M. Best Company ("A.M. Best"),
 
                                       10
<PAGE>   14
 
Moody's Investor's Service ("Moody's"), Standard & Poor's Insurance Rating
Services ("S&P"), and Duff & Phelps. A.M. Best's and Moody's ratings reflect
their current opinion of Anchor National's financial strength and performance in
comparison to others in the life and health insurance industry. S&P's and Duff &
Phelps' ratings measure the ability of an insurance company to meet its
obligations under insurance policies it issues. These two ratings do not measure
the insurer's ability to meet non-policy obligations. These ratings do not
relate to the performance of the Variable Portfolios.
 
REINSURANCE OF PREVIOUSLY ISSUED CONTRACTS
 
     On November 13, 1989, SunAmerica Inc., Anchor National, Integrated
Resources, Inc. ("IRI") and Integrated Resources Life Insurance Company ("IR
Life") entered into an agreement which amended a stock purchase agreement dated
November 1, 1989 (the "Stock Purchase Agreement") between SunAmerica Inc. and
IRI. Under the Stock Purchase Agreement, as amended, Anchor National acquired,
on an assumption reinsurance basis, the variable annuity contracts of IR Life,
including contracts which except, for the issuer, are identical in all material
respects ("reinsured contracts") to the contracts offered by this prospectus.
Thus, Anchor National has all the liabilities and obligations under the
reinsured contracts. All future payments made under the reinsured contracts will
be made directly to or by Anchor National.
 
     If you are a reinsured contract owner, you have the same contract rights
and the same contract values as you did before the reinsurance transaction.
However, Anchor National, instead of IR Life, will fulfill the terms of your
contract. Pursuant to the reinsurance agreement, the separate account originally
held by IR Life with all of its assets was transferred to Anchor National. Thus,
as of the effective date of the reinsurance closing, the assets of the separate
account are only available to satisfy our obligations under the variable annuity
contracts issued by the separate account. The separate account is not chargeable
with liabilities out of any other business that IR Life has conducted, and the
assets of the separate account cannot be reached by IRI or IRI's creditors. (SEE
SEPARATE ACCOUNT BELOW).
 
     The Stock Purchase Agreement, as amended, also provided for the sale of
Integrated Resources Asset Management Corp. ("IRAM") to SunAmerica Inc. This
transaction constituted a change in the control of IRAM. A change in the control
of IRAM constitutes an assignment of the Investment Management Agreement and
series of investment management contracts between IRAM and the Trust, and the
Sub-Advisory Agreement and series of sub-advisory contracts with Wellington
Management Company, LLP. These agreements and contracts terminate automatically
in the event of their assignment. New agreements were approved by the Trust's
Board of Trustees and by shareholders on February 13, 1990. In connection with
the sale of IRAM to SunAmerica Inc., IRAM's name was changed to SunAmerica Asset
Management Corp. ("SAAMCo").
 
SEPARATE ACCOUNT
 
     The separate account was originally established by IR Life pursuant to Iowa
insurance law on January 21, 1985. In fulfillment of the reinsurance agreement,
the separate account was assumed intact by Anchor National on January 18, 1990
and reestablished under California insurance laws. In connection with the
redomestication of Anchor National, the establishment of the separate account
was ratified by the Company under Arizona insurance laws. The separate account
is registered with 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 Anchor National by the SEC.
 
     On September 24, 1990, Variable Annuity Account One(c) ("separate
account(c)") was merged with and into the separate account. The separate
account(c) was a separate account originally established by The Capitol Life
Insurance Company, a subsidiary of IRI, pursuant to Colorado insurance law on
September 23, 1986, and used to fund variable annuity contracts ("Capitol
contracts") that are in all material respects identical to the contracts. The
Capitol contracts were
 
                                       11
<PAGE>   15
 
reinsured to IR Life and, on January 18, 1990, reinsured to us. As a result of
the merger, the reinsured Capitol contracts are now funded through the separate
account. As is the case with the contracts, the reinsured Capitol contracts were
(and continue to be) ultimately funded by the Variable Portfolios of the Trust
and by the general account of Anchor National. The merger did not affect any of
the rights and obligations of the reinsured Capitol contract owners and Anchor
National under the reinsured Capitol contracts or those of contract owners and
Anchor National under the contracts. The merger did not affect those owners'
contract values.
 
     The separate account is registered with the SEC as a unit investment trust
under the Investment Company Act of 1940, as amended. Anchor National owns the
assets of the separate account. However, the assets in the separate account are
not chargeable with liabilities arising our of any other business conducted by
Anchor National. Income, gains and losses (realized and unrealized), resulting
from assets in the separate account are credited to or charged against the
separate account without regard to other income, gains or losses of Anchor
National.
 
GENERAL ACCOUNT
 
     Money allocated to the fixed account option goes into Anchor National's
general account. The general account consists of all of Anchor National's assets
other than assets attributable to a separate account. All of the assets in the
general account are chargeable with the claims of any Anchor National contract
holders as well as all of its creditors. The general account funds are invested
as permitted under state insurance laws.

                           VARIABLE PORTFOLIO OPTIONS
- --------------------------------------------------------------------------------
 
     The contract currently offers eleven Variable Portfolios. These Variable
Portfolios invest in shares of the Trust. These Variable Portfolios operate
similarly to a mutual fund but are only available through the purchase of this
annuity contract. The Variable Portfolios are:

</TABLE>
 
     The Trust is an open-end diversified management investment company
registered under the Investment Company Act of 1940. While a brief summary of
the investment objectives is set forth below, more comprehensive information,
including a discussion of potential risks, is found in the prospectus for the
Trust, attached or enclosed. SAAMCo, an affiliate of Anchor National, is the
investment manager for the Trust. Wellington Management Company, LLP, which is
not affiliated with Anchor National, serves as sub-adviser for the Trust.
 
     There is no assurance that the investment objective of any of the Variable
Portfolios will be met. The contract owners bear the complete investment risk
for Purchase Payments allocated to a division. Contract values will fluctuate in
accordance with the investment performance of the division(s) to which Purchase
Payments are allocated, and in accordance with the imposition of the fees and
charges assessed under the contracts.
 
     Shares of the Trust are and will be issued and redeemed only in connection
with investments in and payments under variable contracts sold by the company
and its affiliate, First SunAmerica Life
 
                                       12
<PAGE>   16
 
Insurance Company, as well as two unaffiliated companies, Presidential Life
Insurance Company and Phoenix Mutual Life Insurance Company. No disadvantage to
contract owners is seen to arise from the fact that the Trust offers its shares
in this fashion.
 
     Additional Variable Portfolios may be established by the Trust from time to
time and may be made available to contract owners. However, there is no
assurance that this will occur.
 
   
VOTING RIGHTS
    
 
     Anchor National is the legal owner of the Trust's shares. However, when a
Variable Portfolio solicits proxies in conjunction with a vote of shareholders,
we must obtain your instructions on how to vote those shares. We vote all of the
shares we own in proportion to your instructions. Should we determine that we
are no longer required to comply with these rules, we will vote the shares in
our own right.
 
SUBSTITUTION OF SECURITIES
 
     If Variable Portfolios become unavailable for investment, we may be
required to substitute shares of another Variable Portfolios. We will seek prior
approval of the SEC and give you notice before substituting shares.
 
- --------------------------------------------------------------------------------
 
                              FIXED ACCOUNT OPTION
- --------------------------------------------------------------------------------
 
ALLOCATIONS
 
     The contract also offers a fixed account option for a one year period. We
call this time period the guarantee period. The fixed account option pays
interest at rate set and guaranteed by Anchor National. The interest rate may
differ from time to time and is set at our sole discretion. We will never credit
less than a 4% annual effective rate to the fixed account option. The interest
rate offered for new Purchase Payments may differ from interest rates offered
for subsequent Purchase Payments and money already in the fixed account option.
Once established, the rates for specified payments do not change during the
guarantee period.
 
     When a guarantee period ends, you may leave your money in the fixed
account. You may also reallocate your money to the Variable Portfolios. If you
want to reallocate your money you must contact us within 30 days after the end
of the current guarantee period and instruct us how to reallocate the money. If
we do not hear from you, we will keep your money in the fixed account where it
will earn the renewal interest rate applicable at that time.
 
- --------------------------------------------------------------------------------
 
                                CONTRACT CHARGES
- --------------------------------------------------------------------------------
 
     There are charges and expenses associated with your contract. These charges
and expenses reduce your investment return. We will not increase the contract
maintenance fee and withdrawal charges under your contract. However, the
investment charges under your contract may increase or decrease. Some states may
require that we charge less than the amounts described below.
 
INSURANCE CHARGES
 
   
     The amount of this charge is 1.40% annually, of the value of your contract
invested in the Variable Portfolios. We deduct the charge from the Variable
Portfolio(s) in which you are invested on a pro-rata basis, daily.
    
 
                                       13
<PAGE>   17
 
   
     The insurance charge compensates us for the mortality and expense risks and
the costs of contract distribution we assume. If these charges do not cover all
expenses, we will pay the difference. Likewise, if these charges exceed our
expenses, we will keep the difference.
    
 
WITHDRAWAL CHARGES
 
     The contract provides a free withdrawal amount every year. (SEE CONTRACT
CHARGES, FREE WITHDRAWAL AMOUNT, PAGE 15.) If you take money out in excess of
the free withdrawal amount, you may incur a withdrawal charge.
 
     We apply a withdrawal charge against each Purchase Payment you put into the
contract. After a Purchase Payment has been in the contract for five complete
years, no withdrawal charge applies. The withdrawal charge equals a percentage
of Purchase Payments you take out of the contract which are still subject to the
withdrawal charge and not previously withdrawn. The withdrawal charge percentage
declines each year a Purchase Payment is in the contract, as follows:

     When calculating the withdrawal charge, we treat withdrawals as coming
first from the Purchase Payments that have been in your contract the longest.
However, for tax purposes, your withdrawals are considered earnings first, then
Purchase Payments.
 
     Whenever possible, we deduct the withdrawal charge from the money remaining
in your contract. If you withdraw all of your contract value, applicable
withdrawal charges are deducted from the amount withdrawn.
 
     We do not assess a withdrawal charge for money withdrawn to pay a death
benefit. Withdrawals made prior to age 59 1/2 may result in a 10% IRS penalty
tax. SEE TAXES, PAGE 25.
 
INVESTMENT CHARGES
 
     Charges are deducted from the Variable Portfolios for the advisory and
other expenses of the underlying Variable Portfolios. THE FEE TABLES LOCATED AT
PAGE 7 illustrate these charges and expenses. For more detailed information on
these investment charges, refer to the attached prospectus for the Trust.
 
CONTRACT MAINTENANCE FEE
 
   
     During the Accumulation Phase, we subtract a $30 contract maintenance fee
from your account, on a pro-rata basis, once per contract year. This charge
compensates us for the cost of contract administration. If your contract was
issued prior to September 1, 1987, we deduct this fee from your contract on
December 31 of each year. In addition, we will waive the fee during the year in
which you fully surrender your contract. If your contract was issued on or after
September 1, 1987, we deduct the fee on your contract anniversary. If you
withdraw your entire contract value, the fee is deducted from that withdrawal.
    
 
TRANSFER FEE
 
     The contract currently provides for 15 free transfers between investment
options each contract year. After that, a charge of $25 applies to each
additional transfer in any one contract year ($10 in Pennsylvania and Texas).
SEE TRANSFERS DURING THE ACCUMULATION PHASE, PAGE 19.

<PAGE>   18
 
ANNUITY CHARGE
 
   
     If you elect to have your income payments made under income option 1, Life
Annuity with 10 or 20 Years Guaranteed, or income option 2, Joint and Survivor
Life Annuity, we do not assess an annuity charge. If you elect income option 3,
Income for a Specified Period, and if your Purchase Payments were made in the
contract year in which income payments begin or in any of the four preceding
contract years, we may assess an annuity charge. This annuity charge equals the
withdrawal charge that would apply if your contract was being surrendered. If
income option 3 is elected by your Beneficiary under the death benefit, we will
not assess an annuity charge.
    
 
PREMIUM TAX
 
     Certain states charge us a tax on the premiums you pay into the contract.
We deduct from your contract these premium tax charges. Currently, we deduct the
charge for premium taxes when you take a full withdrawal or begin the Income
Phase of the contract or upon your death. In the future, we may assess this
deduction at the time you put Purchase Payment(s) into the contract.
 
APPENDIX A provides more information about premium taxes.
 
INCOME TAXES
 
     We do not currently deduct income taxes from your contract. We reserve the
right to do so in the future.
 
REDUCTION OR ELIMINATION OF CHARGES AND EXPENSES, AND ADDITIONAL AMOUNTS
CREDITED
 
     Sometimes sales of the contracts to groups of similarly situated
individuals may lower our administrative and/or sales expenses. We reserve the
right to reduce or waive certain charges and expenses when this type of sale
occurs. In addition, we may also credit additional interest to policies sold to
such groups. We determine which groups are eligible for such treatment. Some of
the criteria used to make a determination are: size of the group; amount of
expected Purchase Payments; relationship existing between us and prospective
purchaser; nature of the purchase; length of time a group of contracts is
expected to remain active; purpose of the purchase and whether that purpose
increases the likelihood that our expenses will be reduced; and/or any other
factors that we believe indicate that administrative and/or sales expenses may
be reduced.
 
     We may make such a determination regarding sales to our employees, our
affiliates' employees and employees of currently contracted broker-dealers, our
registered representatives and immediate family members of all of those
described.
 
     We reserve the right to change or modify any such determination or the
treatment applied to a particular group, at any time.
 
FREE WITHDRAWAL AMOUNT
 
   
     There is a Free Withdrawal Amount which applies to the first withdrawal
during a Contract Year after the first Contract Year. The Free Withdrawal Amount
is equal to the greater of 10% of the aggregate Purchase Payments less prior
withdrawals or Purchase Payments in the contract for longer than five years
minus prior withdrawals. Alternatively, certain Owners of Non-Qualified
Contracts and Contracts issued in connection with IRAs may choose to withdraw
via the Systematic Withdrawal Program amounts which in the aggregate add up to
10% of their initial Purchase Payments annually, without charge. The Systematic
Withdrawal Program is available under such Contracts which were issued on and
after April 1, 1989. To participate in the Systematic Withdrawal Program, Owners
must complete an enrollment form (which describes the program) and send it to
the Company, c/o its Administrative Service Center. Depending on fluctuations in
the net asset value of the Separate Account's Divisions, systematic withdrawals
may reduce or even exhaust Contract Value. (See "Purchases and Contract
Value -- Systematic Withdrawal Program").

                          DESCRIPTION OF THE CONTRACTS
- --------------------------------------------------------------------------------
 
SUMMARY
 
     This contract works in two stages, the Accumulation Phase and the Income
Phase. Your contract is in the Accumulation Phase while you make payments into
the contract. The Income Phase begins when you request that we begin making
payments to you out of the money accumulated in your contract.
 
OWNERSHIP
 
     You, as the contract owner, are entitled to the rights and privileges of
the contract. If you die during the Accumulation Phase, your Beneficiary will
become the owner of the contract, unless you elect otherwise. Joint owners have
equal ownership interests in the contract unless we advise otherwise in writing.
Only spouses may be joint owners.
 
ANNUITANT
 
     The annuitant is the person on whose life we base income payments. You may
change the Annuitant at any time before the Annuity Date. You may also designate
a second person on whose life, together with the annuitant, income payments
depend. If the annuitant dies before the Annuity Date, you must notify us and
select a new annuitant.
 
MODIFICATION OF THE CONTRACT
 
     Only the Company's President, a Vice President or Secretary may approve a
change or waive a provision of the contract. Any change or waiver must be in
writing. We reserve the right to modify the terms of the contract as necessary
to comply with changes in applicable law.
 
ASSIGNMENT
 
     Contracts issued pursuant to Non-qualified plans that are not subject to
Title 1 of the Employee Retirement Income Security Act of 1974 ("ERISA") may be
assigned by the owner at any time during the lifetime of the Annuitant prior to
the Annuity Date. We will not be bound by any assignment until written notice is
received by us at our Annuity Service Center. We are not responsible for the
validity, tax or other legal consequences of any assignment. An assignment will
not affect any payments we may make or actions we may take before we receive
notice of the assignment.
 
     If the contract is issued pursuant to a Qualified plan (or a Non-qualified
plan that is subject to Title 1 of ERISA), it may not be assigned, pledged or
otherwise transferred except under such conditions as may be allowed under
applicable law.
 
     BECAUSE AN ASSIGNMENT MAY BE A TAXABLE EVENT, YOU SHOULD CONSULT A
COMPETENT TAX ADVISER SHOULD YOU WISH TO ASSIGN YOUR CONTRACT.
 
DEATH BENEFIT
 
     If you die during the Accumulation Phase of your contract, we pay a death
benefit to your Beneficiary.
 
     The death benefit is equal to the greater of:
 
     1. the value of your contract at the time we receive satisfactory proof of
        death; or
 
     2. total Purchase Payments less any withdrawals and partial annuitizations
        (and any fees or charges applicable to such distributions), compounded
        at a 5% annual growth rate; or
 
                                       16
<PAGE>   20
 
     3. after your fifth contract year, your contract value on the last contract
        anniversary plus any Purchase Payments and less any withdrawals and
        partial annuitizations (and any fees or charges applicable to such
        distributions) since that contract anniversary.
 
     We do not pay the death benefit if you die after you switch to the Income
Phase. However, if you die during the Income Phase, your Beneficiary receives
any remaining guaranteed income payments in accordance with the income option
you selected. (SEE INCOME PHASE, INCOME OPTIONS, PAGE 22.)
 
     You name your Beneficiary. You may change the Beneficiary at any time,
unless you previously made an irrevocable Beneficiary designation.
 
     We pay the death benefit when we receive satisfactory proof of death. We
consider the following satisfactory proof of death:
 
     1. a certified copy of the death certificate; or
 
     2. a certified copy of a decree of a court of competent jurisdiction as to
        the finding of death; or
 
     3. a written statement by a medical doctor who attended the deceased at the
        time of death; or
 
     4. any other proof satisfactory to us.
 
     We may require additional proof before we pay the death benefit.
 
     The death benefit payment must begin immediately upon receipt of all
necessary documents. In any event, the death benefit must be paid within 5 years
of the date of death unless the Beneficiary elects to have it payable in the
form of an income option. If the Beneficiary elects an income option, it must be
paid over the Beneficiary's lifetime or for a period not extending beyond the
Beneficiary's life expectancy. Payments must begin within one year of the date
of your death. If a Beneficiary does not elect a specific form of pay out within
60 days of our receipt of proof of death, we pay a lump sum death benefit to the
Beneficiary.
 
     If the Beneficiary is the spouse of a deceased owner, he or she can elect
to continue the contract at the then current value. If the Beneficiary/spouse
continues the contract, we do not pay a death benefit to him or her.

PURCHASE PAYMENTS
 
     A Purchase Payment is the money you give us to buy a contract. Any
additional money you give us to invest in the contract after purchase is a
subsequent Purchase Payment.
 
     This chart shows the minimum initial and subsequent Purchase Payments
permitted under your contract. These amounts depend upon whether your contract
is Qualified or Non-qualified for tax purposes. SEE TAXES, PAGE 25.

    Non-Qualified              $1,000                  $500
- --------------------------------------------------------------------
</TABLE>
 
     Prior Company approval is required to accept Purchase Payments greater than
$1,000,000. Also, the optional automatic payment plan allows you to make
subsequent Purchase Payments of as little as $25.00.
 
                                       17
<PAGE>   21
 
   
     The Company reserves the right to refuse any Purchase Payment or subsequent
Purchase Payments, including but not limited to any Purchase Payments which
would cause the contract value to exceed $1,000,000 at the time of the Purchase
Payment. In general, Anchor National will not issue a Qualified contract to
anyone who is age 70 1/2 or older, unless you certify that the minimum
distribution required by the IRS is being made. In addition, we may not issue a
contract to anyone over age 80.
    
 
AUTOMATIC DOLLAR COST AVERAGING PROGRAM
 
     The Dollar Cost Averaging ("DCA") program allows you to invest gradually in
the Variable Portfolios. Under the program you systematically transfer certain
amounts of portfolio value from the Money Market Portfolio, Government and
Quality Bond Portfolio or the 1-year fixed account option (source accounts) to
any other Variable Portfolio. Transfers from the Money Market Portfolio or the
Government and Quality Bond Portfolio may be monthly, quarterly, semiannually or
annually. You may change the frequency at any time by notifying us by telephone
or in writing. Funds in the Money Market Portfolio and the Government and
Quality Bond Portfolio may be transferred as a set dollar amount or as a
percentage of portfolio value.
 
     Transfers from the fixed account option must be made on a percentage basis,
and may not exceed 8% of the value of the fixed account in any contract year.
Transfers from the fixed account may only be made quarterly. The minimum
transfer amount under the DCA program is $100, regardless of the source account.
You may not participate in the DCA program and the systematic withdrawal program
at the same time.
 
     The DCA program is designed to lessen the impact of market fluctuations on
your investment. However, we cannot ensure that you will make a profit. When you
elect the DCA program, you are continuously investing in securities regardless
of fluctuating price levels. You should consider your tolerance for investing
through periods of fluctuating price levels.
 
     We reserve the right to modify, suspend or terminate this program at any
time.
 
     EXAMPLE:
 
     Assume that you want to gradually move $750 each quarter from the Money
     Market Portfolio to the Growth and Income Portfolio over six quarters. You
     set up dollar cost averaging and purchase Accumulation Units at the
     following hypothetical values:
 
<TABLE>
<CAPTION>
- -----------------------------------------------------------
                       ACCUMULATION            UNITS
      QUARTER           UNIT VALUE           PURCHASED
- -----------------------------------------------------------
<S>                 <C>                 <C>
         1                $ 7.50                100
         2                $ 5.00                150
         3                $10.00                75
         4                $ 7.50                100
         5                $ 5.00                150
         6                $ 7.50                100
- -----------------------------------------------------------
</TABLE>
 
     In this example, you paid an average price of only $6.67 per Accumulation
     Unit over six quarters, while the average market price actually was $7.08.
     By investing an equal amount of money each month, you automatically buy
     more Accumulation Units when the market price is low and fewer Accumulation
     Units when the market price is high. This example is for illustrative
     purposes only.
 
ALLOCATION OF PURCHASE PAYMENTS
 
     We invest your Purchase Payments in the fixed and variable investment
options according to your instructions. If we receive a Purchase Payment without
allocation instructions, we invest the money according to your last allocation
instructions. SEE VARIABLE PORTFOLIO OPTIONS, PAGE 12 AND FIXED ACCOUNT OPTION,
PAGE 13.
 
                                       18
<PAGE>   22
 
     In order to issue your contract, we must receive your completed
application, Purchase Payment allocation instructions and any other required
paperwork at our principal place of business. We allocate your initial purchase
payment within two days of receiving it. If we do not have complete information
necessary to issue your contract, we will contact you. If we do not have the
information necessary to issue your contract within 5 business days we will:
 
     - Send your money back to you, or;
 
     - Ask your permission to keep your money until we get the information
       necessary to issue the contract.
 
ACCUMULATION UNITS
 
   
     When you allocate a Purchase Payment to the Variable Portfolios, we credit
your contract with Accumulation Units of the separate account. We base the
number of accumulation units you receive on the unit value of the Variable
Portfolio as of the day we receive your money, if we receive it before 1:00
p.m., Pacific Standard Time ("PST") or on the next business day's unit value, if
we receive your money after 1:00 p.m., PST.
    
 
     We calculate the value of an Accumulation Unit each day that the New York
Stock Exchange ("NYSE") is open as follows:
 
     1. We determine the total value of money invested in a particular Variable
        Portfolio;
 
     2. We subtract from that amount all applicable contract charges; and
 
     3. We divide this amount by the number of outstanding Accumulation Units.
 
     We determine the number of Accumulation Units credited to your contract by
dividing the Purchase Payment by the Accumulation Unit value for the specific
Variable Portfolio.
 
     EXAMPLE:
 
     We receive a $25,000 Purchase Payment from you on Wednesday. You allocate
     the money to the Multi-Asset Portfolio. The value of an Accumulation Unit
     for the Multi-Asset Portfolio is $11.10 when the NYSE closes on Wednesday.
     Your Purchase Payment of $25,000 is then divided by $11.10 and we credit
     your contract on Wednesday night with 2252.52 Accumulation Units of the
     Multi-Asset Portfolio.
 
     Performance of the Variable Portfolios and the charges and expenses under
your contract affect Accumulation Unit values. These factors cause the value of
your contract to go up and down.
 
FREE LOOK
 
     You may cancel your contract within ten days after receiving it (or longer
if required by state law). Anchor National calls this a "free look." To cancel,
you must mail the contract along with your free look request to the Annuity
Service Center at P.O. Box 54299, Los Angeles, California 90054-0299. We will
refund the value of your contract on the day we receive your request. The amount
refunded to you may be more or less than the amount you originally invested.
 
     Certain states require us to return your Purchase Payments upon a free look
request. Additionally, all contracts issued as an IRA require the full return of
Purchase Payments upon a free look.
 
TRANSFERS DURING THE ACCUMULATION PHASE
 
     During the Accumulation Phase you may transfer funds between the Variable
Portfolios and/or the fixed account option. You must transfer at least $500. If
less than $500 will remain in any Variable Portfolio after a transfer, that
amount must be transferred as well. Transfers from the fixed account option may
only be made once each contract year and must be requested during the 30-day
period following the end of the applicable 1-year guarantee period.
 
     You may request transfers of your account value between the Variable
Portfolios and/or the fixed account option in writing or by telephone. We
currently allow 15 free transfers per contract per year.
 
                                       19
<PAGE>   23
 
A charge of $25 ($10 in Pennsylvania and Texas) for each additional transfer in
any contract year applies after the first 15 transfers. We may also assess a $25
fee if you move all your money from a Variable Portfolio to another Variable
Portfolio within 30 days of the contract issue date. Transfers resulting from
your participation in the DCA program count against your 15 free transfers per
contract year.
 
   
     We accept transfer requests by telephone unless you specify not to on your
contract application. Additionally, in the future you may be able to execute
transfers or other financial transactions over the internet. When receiving
instructions over the telephone, we follow appropriate procedures to provide
reasonable assurance that the transactions executed are genuine. Thus, we are
not responsible for any claim, loss or expense from any error resulting from
instructions received over the telephone. Telephone calls authorizing transfers
will be processed on the next business day. The Company reserves the right to
terminate or modify the telephone transfer service at any time.
    
 
   
     Upon implementation of internet account transfers we will have appropriate
procedures in place to provide reasonable assurance that the transactions
executed are genuine. Thus, Anchor National would not be responsible for any
claim, loss or expense from any error resulting from instructions received over
the internet. If we fail to follow any procedures, we may be liable for any
losses due to unauthorized or fraudulent instructions. We reserve the right to
terminate or modify the internet transfer system or procedure at any time.
    
 
   
     We may limit the number of transfers in any contract year or refuse any
transfer request for you or others invested in the contract if we believe that
excessive trading or a specific transfer request or group transfer requests may
have a detrimental effect on unit values or the share prices of the underlying
Variable Portfolios.
    
 
   
     Where permitted by law, we may accept your authorization for a third party
to make transfers for you subject to certain rules. We reserve the right to
suspend or cancel such acceptance at any time and will notify you accordingly.
Additionally, we may restrict the investment options available for transfers
during any period in which such third party acts for you. We will notify such
third party beforehand regarding any restrictions. However, we will not enforce
these restrictions if we are satisfied that:
    
 
     - such third party has been appointed by a court of competent jurisdiction
       to act on your behalf; or
 
     - such third party is a trustee/fiduciary for you or appointed by you to
       act on your behalf for all your financial affairs.
 
     We may provide administrative or other support services to independent
third parties you authorize to make transfers on your behalf. We do not
currently charge extra for providing these support services. This includes, but
is not limited to, transfers between investment options in accordance with
market timing strategies. Such independent third parties may or may not be
appointed with us for the sale of annuities. However, WE DO NOT ENGAGE ANY THIRD
PARTIES TO OFFER INVESTMENT ALLOCATION SERVICES OF ANY TYPE. WE TAKE NO
RESPONSIBILITY FOR THE INVESTMENT ALLOCATION AND TRANSFERS TRANSACTED ON YOUR
BEHALF BY SUCH THIRD PARTIES OR FOR ANY INVESTMENT ALLOCATION RECOMMENDATIONS
MADE BY SUCH PARTIES.
 
     For information regarding transfers during the Income Phase, SEE INCOME
PHASE, TRANSFERS DURING THE INCOME PHASE, PAGE 23.
 
     We reserve the right to modify, suspend, waive or terminate these transfer
provisions at any time.
 
DISTRIBUTION OF CONTRACTS
 
     Registered representatives of broker-dealers sell the contract. Anchor
National pays commissions to these representatives for the sale of the
contracts. We do not expect the total commissions to exceed 5% of your Purchase
Payments. We may also pay a bonus to representatives for contracts which stay
active for a particular period of time, in addition to standard commissions. We
do not deduct commissions paid to registered representatives directly from your
Purchase Payments. No underwriting fees are paid in connection with the
distribution of the contract.
 
                                       20
<PAGE>   24
 
     From time to time, we may pay or allow additional promotional incentives in
the form of cash or other compensation. We reserve the right to offer these
additional incentives only to certain broker-dealers that sell or are expected
to sell, certain minimum amounts of the contract, or other contracts offered by
us. Promotional incentives may change at any time.
 
     SunAmerica Capital Services, Inc., 733 Third Avenue, 4th Floor, New York,
New York 10017 distributes the contracts. SunAmerica Capital Services is an
affiliate of Anchor National, is registered as a broker-dealer under the
Exchange Act of 1934 and is a member of the National Association of Securities
Dealers, Inc.
 
WITHDRAWALS
 
     You can access money in your contract in two ways:
 
     - by making a partial or total withdrawal, and/or;
 
     - by receiving income payments during the Income Phase. (SEE INCOME PHASE,
       PAGE 22.)
 
     Generally, we deduct a withdrawal charge applicable to any total or partial
withdrawal. If you withdraw your entire contract value, a deduction for premium
taxes and the contract maintenance fee also occurs. (SEE CONTRACT CHARGES,
WITHDRAWAL CHARGE, PAGE 14.)
 
     Under most circumstances, the partial withdrawal minimum is $500. We
require that the value left in any investment option be at least $500 after the
withdrawal. You must send a written withdrawal request. Unless you provide
different instructions, partial withdrawals will be made pro rata from each
Variable Portfolio and the fixed account option in which your contract is
invested.
 
     Under certain Qualified plans, access to the money in your contract may be
restricted. Additionally, withdrawals made prior to age 59 1/2 may result in a
10% IRS penalty tax. (SEE TAXES ON PAGE 25.)
 
     We may be required to suspend or postpone the payment of a withdrawal for
any period of time when: (1) the NYSE is closed (other than customary weekend
and holiday closings); (2) trading with the NYSE is restricted; (3) an emergency
exists such that disposal of or determination of the value of shares of the
Variable Portfolios is not reasonably practicable; (4) the SEC, by order, so
permits for the protection of contract owners.
 
     Additionally, we reserve the right to defer payments for a withdrawal from
the fixed account option. Such deferrals are limited to no longer than six
months.
 
SYSTEMATIC WITHDRAWAL PROGRAM
 
     During the Accumulation Phase, you may elect to receive periodic income
payments under the systematic withdrawal program. Under the program, you may
choose to take monthly, quarterly, semiannual or annual payments from your
contract. Electronic transfer of these funds to your bank account is available.
The minimum amount of each withdrawal is $250. You may systematically withdraw
up to 10% of your total Purchase Payments each contract year. There must be at
least $500 remaining in each Variable Portfolio after a withdrawal from your
contract at all times. Withdrawals may be subject to a withdrawal charge and
taxation, and a 10% IRS penalty tax may apply if you are under age 59 1/2. There
is no additional charge for participating in this program.
 
     The program is not available to everyone. Please check with our Annuity
Service Center, which can provide the necessary enrollment forms. Anchor
National reserves the right to modify, suspend or terminate this program at any
time.
 
TEXAS OPTIONAL RETIREMENT PROGRAM
 
     If you participate in the Texas Optional Retirement Program ("ORP") you
must obtain a certificate of termination from your employer before you can
redeem your contract. We impose this requirement on you because the Texas
Attorney General ruled that participants in ORP may redeem
 
                                       21
<PAGE>   25
 
their contract only upon termination of their employment by Texas public
institutions of higher education, or upon retirement death or total disability.
 
MINIMUM CONTRACT VALUE
 
     Where permitted by state law, we may terminate your contract if both of the
following occur: (1) your contract is less than $500 as a result of withdrawals;
and (2) you have not made any Purchase Payments during the past three years. We
will provide you with sixty days written notice. At the end of the notice
period, we will distribute the contract value to you.

                                  INCOME PHASE
- --------------------------------------------------------------------------------
 
ANNUITY DATE
 
     During the Income Phase, we use the money accumulated in your contract to
make regular income payments to you. You may switch to the Income Phase any time
after the first full month of your contract. You select the month and year in
which you want income payments to begin. The first day of that month is the
Annuity Date. You may change your Annuity Date, so long as you do so at least
seven days before the income payments are scheduled to begin. Once you begin
receiving income payments, you cannot change your income option. Except as
discussed under Option 3 below, once you begin receiving income payments, you
cannot otherwise access your money through a withdrawal or surrender.
 
     Income payments must begin on or before the Annuitant's 85th birthday. If
you named joint Annuitants on your contract, the income payments may not be
later than the first day of the month following the 85th birthday of the younger
Annuitant. If you do not choose an Annuity Date, your income payments will
automatically begin on this date. Certain states may require your income
payments to start earlier.
 
     If the Annuity Date is past your 85th birthday, your contract could lose
its status as an annuity under Federal tax laws. This may cause you to incur
adverse tax consequences.
 
     In addition, most Qualified contracts require you to take minimum
distributions after you reach age 70 1/2. (SEE TAXES, PAGE 25.)
 
INCOME OPTIONS
 
     Currently, this contract offers three income options. If you elect to
receive income payments but do not select an option, your income payments will
be made monthly and in accordance with option 1 for a period of 10 years.
 
     We base our calculation of income payments on the life of the Annuitant and
the annuity rates set forth in your contract. As the contract owner, you may
change the Annuitant at any time prior to the Annuity Date. You must notify us
if the Annuitant dies before the Annuity Date and designate a new Annuitant.
 
     OPTION 1 -- LIFE ANNUITY WITH 10 OR 20 YEARS GUARANTEED
 
     This option provides income payments for the longer of (1) the life of the
Annuitant or (2) 10 or 20 years, depending on the number of years you select.
Under this option, we guarantee that income payments will be made for at least
10 or 20 years. If the Annuitant dies before all guaranteed income payments are
made, the remaining income payments go to the Beneficiary under your contract.
 
     OPTION 2 -- JOINT AND SURVIVOR LIFE ANNUITY
 
     This option provides income payments for the life of the Annuitant and for
the life of another designated person. Upon the death of either person, we will
continue to make income payments during the lifetime of the survivor. Income
payments stop whenever the survivor dies.
 
                                       22
<PAGE>   26
 
     OPTION 3 -- INCOME FOR A SPECIFIED PERIOD
 
     This option provides income payments for a guaranteed period ranging from 5
to 30 years. If the Annuitant dies before all of the guaranteed income payments
are made, the remaining income payments will be made to the Beneficiary under
your contract. Additionally, if variable income payments are elected under this
option, you (or the Beneficiary under the contract if the Annuitant dies prior
to all guaranteed payments being made) may redeem the contract value after the
Annuity Date. The amount available upon such redemption will be the discounted
present value of any remaining guaranteed payments.
 
   
     Under this option, if your Purchase Payments were made in the contract year
in which income payments begin or in any of the four preceding contract years,
we may assess an annuity charge. (SEE CONTRACT CHARGES, ANNUITY CHARGE, PAGE
15). This annuity charge equals the withdrawal charge that would apply to those
purchase payments if your contract was being surrendered. If this option is
elected by your Beneficiary under the death benefit, we will not assess an
annuity charge.
    
 
     The value of an Annuity Unit, regardless of the option chosen, takes into
account the Mortality and Expense Risk Charge. Since Option 3 does not contain
an element of mortality risk, no benefit is derived from this charge.
 
     Please read the SAI for a more detailed discussion of the income options.
 
     You can choose income payments that are fixed, variable or both. If at the
date when income payments begin you are invested in the Variable Portfolios
only, your income payments will be variable. If your money is only in the fixed
account at that time, your income payments will be fixed in amount. Further, if
you are invested in both the fixed and variable investment options when payments
begin your payments will be fixed and variable. If income payments are fixed,
Anchor National guarantees the amount of each payment. If the income payments
are variable, the amount is not guaranteed. You may send us a written request to
convert variable income payments to fixed income payments. However, you may not
convert fixed income payments to variable income payments.
 
     We make income payments on a monthly basis. You instruct us to send you a
check or to have the payments directly deposited into your bank account. If
state law allows, we distribute annuities with a contract value of $5,000 or
less in a lump sum. Also, if the selected income option results in income
payments of less than $50 per payment, the frequency of your payments may be
decreased, state law allowing.
 
     If you are invested in the Variable Portfolios after the Annuity Date your
income payments vary depending on four things:
 
     - for life options, your age when payments begin, and;
 
     - the value of your contract in the Variable Portfolios on the Annuity
       Date, and;
 
     - the 5% assumed investment rate used in the annuity table for the
       contract, and;
 
     - the performance of the Variable Portfolios in which you are invested
       during the time you receive income payments.
 
     If you are invested in both the fixed account options and the Variable
Portfolios after the Annuity Date, the allocation of funds between the fixed and
variable options also impacts the amount of your income payments.
 
TRANSFERS DURING THE INCOME PHASE
 
     During the Income Phase, you may transfer funds to the fixed account and/or
among the Variable Portfolios. Transfers during the Income Phase are subject to
the following limitations:
 
     (1) You may not transfer funds to a Variable Portfolio during the first
         year your contract is in the Income Phase. After the first year, you
         may only make one transfer per Variable Portfolio during each contract
         year.
 
     (2) When you make a transfer, you must transfer the entire value of a
         Variable Portfolio.
 
                                       23
<PAGE>   27
 
     (3) Your transfer request must be in writing. We must receive your transfer
         request during the 45 days preceding your contract anniversary. Amounts
         are transferred at the next Annuity Unit value calculation date.
 
     (4) You may not transfer funds from the fixed account option. However,
         amounts may be transferred from the Variable Portfolios to the fixed
         account option.
 
     (5) We reserve the right to modify, suspend or terminate this transfer
         privilege at any time.
 
DEFERMENT OF PAYMENTS
 
     We may defer making fixed income payments for up to six months, or less if
required by law. Interest is credited to you during the deferral period.
 
- --------------------------------------------------------------------------------
 
                                 ADMINISTRATION
- --------------------------------------------------------------------------------
 
     We are responsible for the administrative servicing of your contract.
Please contact our Annuity Service Center at 1-800-445-SUN2, if you have any
comment, question or service request.
 
     We send out transaction confirmations and quarterly statements. It is your
responsibility to review these documents carefully and notify us of any
inaccuracies immediately. We investigate all inquiries. To the extent that we
believe we made an error, we retroactively adjust your contract, provided you
notify us within 30 days of receiving the transaction confirmation or quarterly
statement. Any other adjustments we deem warranted are made as of the time we
receive notice of the error.
 
     We rely significantly on computer systems and applications in our daily
operations. Many of our systems are not presently year 2000 compliant, which
means that because they have historically used only two digits to identify the
year in a date, they will fail to distinguish dates in the "2000s" from dates in
the "1900s." Anchor National's business, financial condition and results of
operations could be materially and adversely affected by the failure of our
systems and applications (and those operated by third parties interfacing with
our systems and applications) to properly operate or manage these dates.
 
   
     Anchor National has a coordinated plan to repair or replace these
noncompliant systems and to obtain similar assurances from third parties
interfacing with our systems and applications. In fiscal 1997, the Company's
parent recorded a $15.0 million provision for estimated programming costs to
make necessary repairs of certain specific noncompliant systems, of which $6.2
million was allocated to Anchor National. Anchor National's management is making
expenditures which we expect will ultimately total $5.0 million to replace
certain other noncompliant systems. Total expenditures relating to the
replacement of noncompliant systems will be capitalized by the Company as
software costs and will be amortized over future periods. Both phases of the
project are progressing according to plan and were substantially completed by
the end of calendar 1998. Testing of both the repaired and replacement systems
is being conducted during calendar 1999.
    
 
     In addition, we distributed a year 2000 questionnaire to our significant
suppliers, distributors, financial institutions, lessors and others we do
business with to evaluate their year 2000 compliance plans and state of
readiness and to determine how our systems and applications may be affected by
their failure to solve their own year 2000 issues. To date, however, we have
only received preliminary feedback from such parties and have not independently
confirmed any information received from other parties with respect to the year
2000 issues. Therefore, we cannot assure that such other parties will complete
their year 2000 conversions in a timely fashion or will not suffer a year 2000
business disruption that may adversely affect our financial condition and
results of operations.
 
     Because we expect to complete our year 2000 conversion prior to any
potential disruption to our business, we have not developed a comprehensive year
2000 contingency plan. Anchor National closely monitors the progression of its
plan for compliance, and if necessary, would devote additional resources to
assure the timely completion of its year 2000 plan. If we determine that our
business is
 
                                       24
<PAGE>   28
 
at material risk of disruption due to the year 2000 issue or anticipate that our
year 2000 conversion will not be completed in a timely fashion, we will work to
enhance our contingency plans.
 
     The above statements are forward-looking. The costs of our year 2000
conversion, the date which we have set to complete such conversion and the
possible risks associated with the year 2000 issue are based on our current
estimates and are subject to various uncertainties that could cause actual
results to differ materially from our expectations. Such uncertainties include,
among others, our success in identifying systems and applications that are not
year 2000 compliant, the nature and amount of programming required to upgrade or
replace each of the affected systems and applications, the availability of
qualified personnel, consultants and other resources, and the success of the
year 2000 conversion efforts of others.

                                     TAXES
- --------------------------------------------------------------------------------
 
     NOTE: WE PREPARED THE FOLLOWING INFORMATION ON TAXES AS A GENERAL
DISCUSSION OF THE SUBJECT. IT IS NOT TAX ADVICE. WE CAUTION YOU TO SEEK
COMPETENT TAX ADVICE ABOUT YOUR OWN CIRCUMSTANCES. WE DO NOT GUARANTEE THE TAX
STATUS OF YOUR ANNUITY. TAX LAWS CONSTANTLY CHANGE, THEREFORE WE CANNOT
GUARANTEE THAT THE INFORMATION CONTAINED HEREIN IS COMPLETE AND/OR ACCURATE.
 
ANNUITY CONTRACTS IN GENERAL
 
     The Internal Revenue Code ("IRC") provides for special rules regarding the
tax treatment of annuity contracts. Generally, taxes on the earnings in your
annuity contract are deferred until you take the money out. Qualified retirement
investments automatically provide tax deferral regardless of whether the
underlying contract is any annuity. Different rules apply depending on how you
take the money out and whether your contract is Qualified or Non-qualified.
 
     If you do not purchase your contract under a pension plan, a specially
sponsored employer program or an IRA, your contract is referred to as a
Non-qualified contract. A Non-qualified contract receives different tax
treatment than a Qualified contract. In general, your cost basis in a Non-
qualified contract is equal to the Purchase Payments you put into the contract.
You have already been taxed on the cost basis in your contract.
 
     If you purchase your contract under a pension plan, a specially sponsored
employer program or as an individual retirement account, your contract is
referred to as a Qualified contract. Examples of qualified plans are: IRAs, Roth
IRAs, Tax-Sheltered Annuities (referred to as 403(b) contracts), H.R. 10 Plans
(referred to as Keogh Plans) and pension and profit sharing plans, including
401(k) plans. Typically you have not paid any tax on the Purchase Payments used
to buy your contract and therefore, you have no cost basis in your contract.
 
TAX TREATMENT OF DISTRIBUTIONS -- NON-QUALIFIED CONTRACTS
 
     If you make a withdrawal from a Non-qualified contract, the IRC treats such
a withdrawal as first coming from the earnings and then as coming from your
Purchase Payments. For income payments, any portion of each payment that is
considered a return of your Purchase Payment will not be taxed. Withdrawn
earnings are treated as income to you and are taxable. The IRC provides for a
10% penalty tax on any earnings that are withdrawn other than in conjunction
with the following circumstances: (1) after reaching age 59 1/2; (2) when paid
to your Beneficiary after you die; (3) after you become disabled (as defined in
the IRC); (4) when paid in a series of substantially equal installments made for
your life or for the joint lives of you and you Beneficiary; (5) under an
immediate annuity; or (6) which come from Purchase Payments made prior to August
14, 1982.
 
                                       25
<PAGE>   29
 
TAX TREATMENT OF DISTRIBUTIONS -- QUALIFIED CONTRACTS
 
     Generally, you have not paid any taxes on the Purchase Payments used to buy
a Qualified contract. Any amount of money you take out as a withdrawal or as
income payments is taxable income. The IRC further provides for a 10% penalty
tax on any withdrawal or income payment paid to you other than in conjunction
with the following circumstances: (1) after reaching age 59 1/2; (2) when paid
to your Beneficiary after you die; (3) after you become disabled (as defined in
the IRC); (4) when paid in a series of substantially equal installments made for
your life or for the joint lives of you and your Beneficiary; (5) to the extent
such withdrawals do not exceed limitations set by the IRC for amounts paid
during the taxable year for medical care; (6) to fund higher education expenses
(as defined in IRC); (7) to fund certain first-time home purchase expenses; and,
except in the case of an IRA; (8) when you separate from service after attaining
age 55; and (9) when paid to an alternate payee pursuant to a qualified domestic
relations order.
 
     The IRC limits the withdrawal of Purchase Payments from certain
Tax-Sheltered Annuities. Withdrawals can only be made when an owner: (1) reaches
age 59 1/2; (2) leaves his or her job; (3) dies; (4) becomes disabled (as
defined in the IRC); or (5) experiences hardship (as defined in the IRC). In the
case of hardship, the owner can only withdraw Purchase Payments.
 
MINIMUM DISTRIBUTIONS
 
     Generally, the IRS requires that you begin taking annual distributions from
Qualified annuity contracts by April 1 of the calendar year following the later
of (1) the calendar year in which you attain age 70 1/2 or (2) the calendar year
in which you retire. Failure to satisfy the minimum distribution requirements
may result in a tax penalty. You should consult your tax advisor for more
information.
 
DIVERSIFICATION
 
     The IRC imposes certain diversification requirements on the underlying
investments for a variable annuity. We believe that the manager of the
underlying Variable Portfolios monitors the Variable Portfolios so as to comply
with these requirements. To be treated as a variable annuity for tax purposes,
the underlying investments must meet these requirements.
 
     The diversification regulations do not provide guidance as to the
circumstances under which you, because of the degree of control you exercise
over the underlying investments, and not Anchor National, would be considered
the owner of the shares of the Variable Portfolios. It is unknown to what extent
owners are permitted to select investments, to make transfers among Variable
Portfolios or the number and type of Variable Portfolios owners may select from.
If any guidance is provided which is considered a new position, then the
guidance would generally be applied prospectively. However, if such guidance is
considered not to be a new position, it may be applied retroactively. This would
mean you, as the owner of the contract, could be treated as the owner of the
underlying Variable Portfolios. Due to the uncertainty in this area, we reserve
the right to modify the contract in an attempt to maintain favorable tax
treatment.

                                PERFORMANCE DATA

         Performance data for the various Divisions of the Separate Account are
determined in the manner described below.

Money Market Division

         The annualized current yield and the effective yield for the Money
Market Division for the 7 day period ended December 31, 1998 were 3.14% and
3.19%, 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 $30 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 incurred, during such 7 day
period. The Contract Maintenance Fee is first allocated among the Divisions and
the General Account so that each Division's allocated portion of the charge is
proportional to the percentage of the number of Contract Owners' accounts that
have money allocated to that Division. The portion of the Fee allocable to the
Money Market Division 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 Money
Market Division. 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 Money Market Division 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 Money Market Division. 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].

         Net investment income for yield quotation purposes will not include
either realized capital



                                       2
<PAGE>   38

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 or Annuity Charges.

         The yields quoted should not be considered a representation of the
yield of the Money Market Division 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 Money Market Division and changes in interest rates on
such investments, but also on factors such as a Contract 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
Money Market Division and for providing a basis for comparison with other
investment alternatives. However, the Money Market Division's yield fluctuates,
unlike bank deposits or other investments that typically pay a fixed yield for a
stated period of time.

Other Divisions

         Divisions of the Separate Account other than the Money Market Division
compute their performance data as "total return." The total returns of the
various Divisions over the last 1, 5 and 10 year periods, and since their
inception, are shown below, both with/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.


* Formerly the Convertible Securities Division

         These figures show the total return hypothetically experienced by
Contracts funded through the various Divisions of the Account over the time
periods shown.

         Total return for a Division represents a 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 Division 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



                                       3
<PAGE>   39


the same period. The total rate of return (T) is computed so that it satisfies
the formula:

                  P(1+T)n = ERV

         where:

                   P =     a hypothetical initial payment of $1000
                   T =     average annual total return
                   n =     number of years


           ERV             = ending redeemable value of a hypothetical $1000
                           payment made at the beginning of the 1, 5, or 10 year
                           periods at the end of the 1, 5, or 10 year periods
                           (or fractional portion thereof).

         The total return figures given reflect the effects of both
non-recurring 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 Money Market Division, 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 in the case of the first of the two figures given in
the table above for each Division and time period. Because the impact of
Contract Maintenance Fees on a particular Contract Owner's account would
generally have differed 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 account over
these same time periods would generally have been different from those given
above. As with the Money Market Division yield figures, total return figures are
derived from historical data and are not intended to be a projection of future
performance.

                                 INCOME PAYMENTS

Annuity Unit Value

         The value of an Annuity Unit is determined independently for each
Separate Account Division.

         For each Division, the value of an Annuity Unit for any Valuation
Period is determined by multiplying the Annuity Unit value for the immediately
preceding Valuation Period by the net investment factor for the Valuation Period
for which the Annuity Unit value is being calculated and multiplying the result
by an interest factor which offsets the effect of the investment earnings rate
of five percent (5%) per annum that is assumed in the annuity table contained in
the Contract.

         The net investment factor for each Division for a Valuation Period is
determined by dividing (a) by (b) and subtracting (c) from the result where: (a)
is the value of an Accumulation Unit from the applicable Division as of the end
of the current Valuation Period; (b) is the value of an Accumulation Unit for
the applicable Division as of the end of the immediately preceding Valuation
Period; and (c) is a factor representing the daily charge for mortality and
expense risks and administration of 1.40% per annum.

Amount of Income Payments

         The initial income payment is determined by applying the Contract
Value, less any


                                       4
<PAGE>   40


premium tax, and less any Annuity Charge (if annuity option 3 is elected), to
the annuity table specified in the Contract. Those tables are based on a set
amount per $1,000 of proceeds applied. The appropriate rate must be determined
by the sex and adjusted age of the Annuitant and joint Annuitant, if any. The
adjusted age is determined from the actual age to the nearest birthday at the
Annuity Date according to the table below. The Adjusted Age Table is used to
correct for population mortality improvements over time.

         The dollars applied are then divided by 1,000 and multiplied by the
appropriate annuity factor to indicate the amount of the first income payment.
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 income payment. The
number of Annuity Units determined for the first income payment remains constant
for the second and subsequent monthly payments.



Subsequent Monthly Payments

         The amount of the second and subsequent income payments is determined
by multiplying the number of Annuity Units by the Annuity Unit value as of the
Valuation Period next preceding the date on which each income payment is due.
The dollar amount of the first income payment determined as above is divided by
the value of an Annuity Unit as of the Annuity Date to establish the number of
Annuity Units representing each income payment. The number of Annuity Units
determined for the first income payment remains constant for the second and
subsequent monthly 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 income option
elected. For a lump sum payment received as a total surrender (total
redemption),




                                       5
<PAGE>   41


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. Contract Owners, Annuitants and
Beneficiaries under the contracts should seek competent financial advice about
the tax consequences of distributions under the retirement plan under which the
contracts are purchased.

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

Withholding Tax on Distributions

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

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

         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


                                       6
<PAGE>   42


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





                                       7
<PAGE>   43


Tax Treatment of Assignments

         An assignment of a contract may have tax consequences, and may also be
prohibited by ERISA in some circumstances. Contract 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. Contract 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 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 Accounts

                  Section 408(b) of the Code permits eligible individuals to
         contribute to an individual retirement program known as an "Individual
         Retirement Account" ("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.

         (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.

                              FINANCIAL STATEMENTS

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholder of
Anchor National Life Insurance Company
 
     In our opinion, the accompanying consolidated balance sheet and the related
consolidated income statement and statement of cash flows present fairly, in all
material respects, the financial position of Anchor National Life Insurance
Company and its subsidiaries (the "Company")at September 30, 1998 and 1997, and
the results of their operations and their cash flows for each of the three years
in the period ended September 30, 1998, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. NATURE OF OPERATIONS
 
     Anchor National Life Insurance Company (the "Company") is a wholly owned
indirect subsidiary of SunAmerica Inc. (the "Parent"). The Company is an
Arizona-domiciled life insurance company and conducts its business through three
segments: annuity operations, asset management operations and broker-dealer
operations. Annuity operations include the sale and administration of fixed and
variable annuities and guaranteed investment contracts. Asset management
operations, which includes the sale and management of mutual funds, is conducted
by SunAmerica Asset Management Corp. Broker-dealer operations include the sale
of securities and financial services products, and are conducted by Royal
Alliance Associates, Inc.
 
     The operations of the Company are influenced by many factors, including
general economic conditions, monetary and fiscal policies of the federal
government, and policies of state and other regulatory authorities. The level of
sales of the Company's financial products is influenced by many factors,
including general market rates of interest, strength, weakness and volatility of
equity markets, and terms and conditions of competing financial products. The
Company is exposed to the typical risks normally associated with a portfolio of
fixed-income securities, namely interest rate, option, liquidity and credit
risk. The Company controls its exposure to these risks by, among other things,
closely monitoring and matching the duration of its assets and liabilities,
monitoring and limiting prepayment and extension risk in its portfolio,
maintaining a large percentage of its portfolio in highly liquid securities, and
engaging in a disciplined process of underwriting, reviewing and monitoring
credit risk. The Company also is exposed to market risk, as market volatility
may result in reduced fee income in the case of assets managed in mutual funds
and held in separate accounts.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     BASIS OF PRESENTATION: The accompanying consolidated financial statements
have been prepared in accordance with generally accepted accounting principles
and include the accounts of the Company and all of its wholly owned
subsidiaries. All significant intercompany accounts and transactions are
eliminated in consolidation. Certain prior period amounts have been reclassified
to conform with the 1998 presentation.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions
that affect the amounts reported in the financial statements and the
accompanying notes. Actual results could differ from those estimates.
 
     INVESTMENTS: Cash and short-term investments primarily include cash,
commercial paper, money market investments, repurchase agreements and short-term
bank participations. All such investments are carried at cost plus accrued
interest, which approximates fair value, have maturities of three months or less
and are considered cash equivalents for purposes of reporting cash flows.
 
     Bonds, notes and redeemable preferred stocks available for sale and common
stocks are carried at aggregate fair value and changes in unrealized gains or
losses, net of tax, are credited or charged directly to shareholder's equity.
Bonds, notes and redeemable preferred stocks are reduced to estimated net
realizable value when necessary for declines in value considered to be other
than temporary. Estimates of net realizable value are subjective and actual
realization will be dependent upon future events.
 
     Mortgage loans are carried at amortized unpaid balances, net of provisions
for estimated losses. Real estate is carried at the lower of cost or fair value.
Other invested assets include investments in limited partnerships, which are
accounted for by using the cost method of accounting; separate account
investments; leveraged leases; policy loans, which are carried at unpaid
balances; and collateralized mortgage obligation residuals.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     Realized gains and losses on the sale of investments are recognized in
operations at the date of sale and are determined by using the specific cost
identification method. Premiums and discounts on investments are amortized to
investment income by using the interest method over the contractual lives of the
investments.
 
     INTEREST RATE SWAP AGREEMENTS: The net differential to be paid or received
on interest rate swap agreements ("Swap Agreements") entered into to reduce the
impact of changes in interest rates is recognized over the lives of the
agreements, and such differential is classified as Investment Income or Interest
Expense in the income statement. Initially, Swap Agreements are designated as
hedges and, therefore, are not marked to market. However, when a hedged
asset/liability is sold or repaid before the related Swap Agreement matures, the
Swap Agreement is marked to market and any gain/loss is classified with any
gain/loss realized on the disposition of the hedged asset/liability.
Subsequently, the Swap Agreement is marked to market and the resulting change in
fair value is included in Investment Income in the income statement. When a Swap
Agreement that is designated as a hedge is terminated before its contractual
maturity, any resulting gain/loss is credited/charged to the carrying value of
the asset/liability that it hedged and is treated as a premium/discount for the
remaining life of the asset/liability.
 
     DEFERRED ACQUISITION COSTS: Policy acquisition costs are deferred and
amortized, with interest, in relation to the incidence of estimated gross
profits to be realized over the estimated lives of the annuity contracts.
Estimated gross profits are composed of net interest income, net realized
investment gains and losses, variable annuity fees, surrender charges and direct
administrative expenses. Costs incurred to sell mutual funds are also deferred
and amortized over the estimated lives of the funds obtained. Deferred
acquisition costs ("DAC") consist of commissions and other costs that vary with,
and are primarily related to, the production or acquisition of new business.
 
     As debt and equity securities available for sale are carried at aggregate
fair value, an adjustment is made to DAC equal to the change in amortization
that would have been recorded if such securities had been sold at their stated
aggregate fair value and the proceeds reinvested at current yields. The change
in this adjustment, net of tax, is included with the change in net unrealized
gains/losses on debt and equity securities available for sale that is credited
or charged directly to shareholder's equity. DAC have been decreased by
$7,000,000 at September 30, 1998 and $16,400,000 at September 30, 1997 for this
adjustment.
 
     VARIABLE ANNUITY ASSETS AND LIABILITIES: The assets and liabilities
resulting from the receipt of variable annuity premiums are segregated in
separate accounts. The Company receives administrative fees for managing the
funds and other fees for assuming mortality and certain expense risks. Such fees
are included in Variable Annuity Fees in the income statement.
 
     GOODWILL: Goodwill, amounting to $23,339,000 at September 30, 1998, is
amortized by using the straight-line method over periods averaging 25 years and
is included in Other Assets in the balance sheet. Goodwill is evaluated for
impairment when events or changes in economic conditions indicate that the
carrying amount may not be recoverable.
 
     CONTRACTHOLDER RESERVES: Contractholder reserves for fixed annuity
contracts and guaranteed investment contracts are accounted for as
investment-type contracts in accordance with Statement of Financial Accounting
Standards No. 97, "Accounting and Reporting by Insurance Enterprises for Certain
Long-Duration Contracts and for Realized Gains and Losses from the Sale of
Investments," and are recorded at accumulated value (premiums received, plus
accrued interest, less withdrawals and assessed fees).

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     FEE INCOME: Variable annuity fees, asset management fees and surrender
charges are recorded in income as earned. Net retained commissions are
recognized as income on a trade date basis.
 
     INCOME TAXES: The Company is included in the consolidated federal income
tax return of the Parent and files as a "life insurance company" under the
provisions of the Internal Revenue Code of 1986. Income taxes have been
calculated as if the Company filed a separate return. Deferred income tax assets
and liabilities are recognized based on the difference between financial
statement carrying amounts and income tax bases of assets and liabilities using
enacted income tax rates and laws.
 
     RECENTLY ISSUED ACCOUNTING STANDARDS: In June 1997, the Financial
Accounting Standards Board (the "FASB") issued Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income" ("SFAS 130") and Statement
of Financial Accounting Standards No. 131, "Disclosure about Segments of an
Enterprise and Related Information" ("SFAS 131").
 
     SFAS 130 establishes standards for reporting comprehensive income and its
components in a full set of general purpose financial statements. SFAS 130 is
effective for the Company as of October 1, 1998 and is not included in these
financial statements.
 
     SFAS 131 establishes standards for the disclosure of information about the
Company's operating segments. SFAS 131 is effective for the year ending
September 30, 1999 and is not included in these financial statements.
 
     Implementation of SFAS 130 and SFAS 131 will not have an impact on the
Company's results of operations, financial condition or liquidity.
 
     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133"). SFAS 133 addresses the accounting for derivative instruments, including
certain derivative instruments embedded in other contracts, and hedging
activities. SFAS 133 is effective for the Company as of October 1, 1999 and is
not included in these financial statements. The Company has not completed its
analysis of the effect of SFAS 133, but management believes that it will not
have a material impact on the Company's results of operations, financial
condition or liquidity.

     Expenses incurred to manage the investment portfolio amounted to $1,910,000
for the year ended September 30, 1998, $2,050,000 for the year ended September
30, 1997, and $1,737,000 for the year ended September 30, 1996, and are included
in General and Administrative Expenses in the income statement.
 
     At September 30, 1998, no investment exceeded 10% of the Company's
consolidated shareholder's equity.
 
     At September 30, 1998, mortgage loans were collateralized by properties
located in 29 states, with loans totaling approximately 21% of the aggregate
carrying value of the portfolio secured by properties located in California and
approximately 14% by properties located in New York. No more than 8% of the
portfolio was secured by properties in any other single state.
 
     At September 30, 1998, bonds, notes and redeemable preferred stocks
included $167,564,000 of bonds and notes not rated investment grade. The Company
had no material concentrations of non-investment-grade assets at September 30,
1998.
 
     At September 30, 1998, the carrying value of investments in default as to
the payment of principal or interest was $917,000, all of which were mortgage
loans. Such nonperforming investments had an estimated fair value equal to their
carrying value.
 
     As a component of its asset and liability management strategy, the Company
utilizes Swap Agreements to match assets more closely to liabilities. Swap
Agreements are agreements to exchange with a counterparty interest rate payments
of differing character (for example, variable-rate payments exchanged for
fixed-rate payments) based on an underlying principal balance (notional
principal) to hedge against interest rate changes. The Company typically
utilizes Swap Agreements to create a hedge that effectively converts
floating-rate assets and liabilities to fixed-rate instruments. At September 30,
1998, the Company had one outstanding Swap Agreement with a notional principal
amount of $21,538,000, which matures in December 2024. The net interest paid
amounted to $278,000 and $125,000 for the years ended September 30, 1998 and
1997, respectively, and is included in Interest Expense on Guaranteed Investment
Contracts in the income statement.
 
     At September 30, 1998, $5,154,000 of bonds, at amortized cost, were on
deposit with regulatory authorities in accordance with statutory requirements.

 4. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following estimated fair value disclosures are limited to reasonable
estimates of the fair value of only the Company's financial instruments. The
disclosures do not address the value of the Company's recognized and
unrecognized nonfinancial assets (including its real estate investments and
other invested assets except for cost-method partnerships) and liabilities or
the value of anticipated future business. The Company does not plan to sell most
of its assets or settle most of its liabilities at these estimated fair values.
 
     The fair value of a financial instrument is the amount at which the
instrument could be exchanged in a current transaction between willing parties,
other than in a forced or liquidation sale. Selling expenses and potential taxes
are not included. The estimated fair value amounts were determined using
available market information, current pricing information and various valuation
methodologies. If quoted market prices were not readily available for a
financial instrument, management determined an estimated fair value.
Accordingly, the estimates may not be indicative of the amounts the financial
instruments could be exchanged for in a current or future market transaction.
 
     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value:
 
     CASH AND SHORT-TERM INVESTMENTS: Carrying value is considered to be a
reasonable estimate of fair value.
 
     BONDS, NOTES AND REDEEMABLE PREFERRED STOCKS: Fair value is based
principally on independent pricing services, broker quotes and other independent
information.
 
     MORTGAGE LOANS: Fair values are primarily determined by discounting future
cash flows to the present at current market rates, using expected prepayment
rates.
 
     COMMON STOCKS: Fair value is based principally on independent pricing
services, broker quotes and other independent information.
 
     COST-METHOD PARTNERSHIPS: Fair value of limited partnerships accounted for
by using the cost method is based upon the fair value of the net assets of the
partnerships as determined by the general partners.
 
     VARIABLE ANNUITY ASSETS HELD IN SEPARATE ACCOUNTS: Variable annuity assets
are carried at the market value of the underlying securities.
 
     RESERVES FOR FIXED ANNUITY CONTRACTS: Deferred annuity contracts and single
premium life contracts are assigned a fair value equal to current net surrender
value. Annuitized contracts are valued based on the present value of future cash
flows at current pricing rates.
 
     RESERVES FOR GUARANTEED INVESTMENT CONTRACTS: Fair value is based on the
present value of future cash flows at current pricing rates and is net of the
estimated fair value of a hedging Swap Agreement, determined from independent
broker quotes.
 
     PAYABLE TO BROKERS FOR PURCHASES OF SECURITIES: Such obligations represent
net transactions of a short-term nature for which the carrying value is
considered a reasonable estimate of fair value.
 
     VARIABLE ANNUITY LIABILITIES RELATED TO SEPARATE ACCOUNTS: Fair values of
contracts in the accumulation phase are based on net surrender values. Fair
values of contracts in the payout phase are based on the present value of future
cash flows at assumed investment rates.
 
     SUBORDINATED NOTES PAYABLE TO PARENT: Fair value is estimated based on the
quoted market prices for similar issues.

 5. SUBORDINATED NOTES PAYABLE TO PARENT
 
     Subordinated notes and accrued interest payable to Parent totaled
$39,182,000 at interest rates ranging from 8.5% to 9% at September 30, 1998, and
require principal payments of $23,060,000 in 1999, $5,400,000 in 2000 and
$10,000,000 in 2001.
 
 6. REINSURANCE
 
     On August 11, 1998, the Company entered into a modified coinsurance
transaction, approved by the Arizona Department of Insurance, which involves the
ceding of approximately $5,000,000,000 of variable annuities to ANLIC Insurance
Company (Cayman), a Cayman Islands stock life insurance company, effective
December 31, 1997. As a part of this transaction, the Company received cash
amounting to approximately $188,700,000, and recorded a corresponding reduction
of DAC related to the coinsured annuities.

 6. REINSURANCE (CONTINUED)
     As payments are made to the reinsurer, the reduction of DAC is relieved.
The net reduction in DAC at September 30, 1998 was $166,631,000. Certain
expenses related to this transaction are being charged directly to DAC
amortization in the income statement. The net effect of this transaction in the
income statement is not material.
 
 7. CONTINGENT LIABILITIES
 
     The Company has entered into three agreements in which it has provided
liquidity support for certain short-term securities of two municipalities by
agreeing to purchase such securities in the event there is no other buyer in the
short-term marketplace. In return the Company receives a fee. The maximum
liability under these guarantees is $242,600,000. Management does not anticipate
any material future losses with respect to these liquidity support facilities.
An additional $51,000,000 has been committed to investments in the process of
being funded or to be available in the case of certain natural disasters, for
which the Company receives a fee.
 
     The Company is involved in various kinds of litigation common to its
businesses. These cases are in various stages of development and, based on
reports of counsel, management believes that provisions made for potential
losses relating to such litigation are adequate and any further liabilities and
costs will not have a material adverse impact upon the Company's financial
position or results of operations.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
12. SUBSEQUENT EVENTS
 
     On July 15, 1998, the Company entered into a definitive agreement to
acquire the individual life business and the individual and group annuity
business of MBL Life Assurance Corporation ("MBL Life") via a 100% coinsurance
transaction for approximately $130,000,000 in cash. The transaction will include
approximately $2,000,000,000 of universal life reserves and $3,000,000,000 of
fixed annuity reserves. The Company plans to reinsure a large portion of the
mortality risk associated with the acquired block of universal life business.
Completion of this acquisition is expected by the end of calendar year 1998 and
is subject to customary conditions and required approvals. Included in this
block of business is approximately $250,000,000 of individual life business and
$500,000,000 of group annuity business whose contract owners are residents of
New York State ("the New York Business"). Approximately six months subsequent to
completion of the transaction, the New York Business will be acquired by the
Company's New York affiliate, First SunAmerica Life Insurance Company, and the
remainder of the business will be acquired by the Company via assumption
reinsurance agreements between MBL Life and the respective companies, which will
supersede the coinsurance agreement. The $130,000,000 purchase price will be
allocated between the Company and its affiliate based on their respective
assumed life insurance reserves.
 
     On August 20, 1998, the Parent announced that it has entered into a
definite agreement to merge with and into American International Group, Inc.
("AIG"). Under the terms of the agreement, each share of the Parent's common
stock (including Nontransferable Class B) will be exchanged for 0.855 shares of
AIG's common stock. The transaction will be treated as a pooling of interests
for accounting purposes and will be a tax-free reorganization. The transaction
was approved by both the Parent's and AIG's shareholders on November 18, 1998,
and, subject to various regulatory approvals, will be completed in late 1998 or
early 1999.

                        REPORT OF INDEPENDENT ACCOUNTANTS


March 22, 1999


To the Board of Directors of Anchor National Life Insurance Company
and the Contractholders of its separate account, Variable Annuity Account One


In our opinion, the accompanying statement of net assets, including the schedule
of portfolio investments, and the related statements of operations and of
changes in net assets present fairly, in all material respects, the financial
position of each of the Variable Accounts constituting Variable Annuity Account
One, a separate account of Anchor National Life Insurance Company (the "Separate
Account") at December 31, 1998, the results of their operations for the year
then ended, and the changes in their net assets for the two years then ended, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Separate Account's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities owned at
December 31, 1998 by correspondence with the custodian, provide a reasonable
basis for the opinion expressed above.

                          VARIABLE ANNUITY ACCOUNT ONE
                                       OF
                     ANCHOR NATIONAL LIFE INSURANCE COMPANY

                          NOTES TO FINANCIAL STATEMENTS

1.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        Variable Annuity Account One 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 SunAmerica Inc. On January 1, 1999,
        SunAmerica Inc. merged with and into American International Group, Inc.
        in a tax-free reorganization that has been treated as a pooling of
        interests for accounting purposes. Immediately prior to the merger,
        SunAmerica Inc. transferred substantially all of its net assets to its
        wholly-owned subsidiary SunAmerica Holdings, Inc., a Delaware
        Corporation. On January 4, 1999, SunAmerica Holdings, Inc. 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 eleven variable portfolios (the
        "Variable Accounts"). Each of the Variable Accounts is invested solely
        in the shares of a designated portfolio of the Anchor Series Trust (the
        "Trust"). The Trust is a diversified, open-end, affiliated investment
        company, which retains an investment advisor to assist in the investment
        activities of the Trust. The contractholder may elect to have payments
        allocated to a guaranteed-interest fund of the Company (the "General
        Account"), which is not a part of the Separate Account. The financial
        statements include balances allocated by the contractholder to the
        eleven Variable Accounts and do not include balances allocated to the
        General Account.

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

        The FOREIGN SECURITIES PORTFOLIO seeks long-term capital appreciation.
        This portfolio invests primarily in a diversified group of equity
        securities issued by foreign companies and primarily denominated in
        foreign currencies.

        The CAPITAL APPRECIATION PORTFOLIO seeks long-term capital appreciation.
        This portfolio invests in growth equity securities which are widely
        diversified by industry and company and may engage in transactions
        involving stock index futures and options thereon as a hedge against
        changes in market conditions.

        The GROWTH PORTFOLIO seeks capital appreciation. This portfolio invests
        in growth equity securities and may engage in transactions involving
        stock index futures and options thereon as a hedge against changes in
        market conditions.

                     ANCHOR NATIONAL LIFE INSURANCE COMPANY

                          NOTES TO FINANCIAL STATEMENTS


1.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

        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 which are expected to provide favorable returns in periods of
        rising inflation.

        The GROWTH AND INCOME PORTFOLIO seeks to provide high current income and
        long-term capital appreciation. This portfolio invests primarily in
        securities that provide the potential for growth and offer income, such
        as dividend-paying stocks and securities convertible into common stock.
        This portfolio may also engage in transactions involving stock index
        futures and options thereon as a hedge against changes in market
        conditions.

        The STRATEGIC MULTI-ASSET PORTFOLIO seeks high long-term total
        investment return. This portfolio invests in growth equity securities,
        aggressive growth equity securities, investment grade bonds, high-yield,
        high-risk bonds, international equity securities and money market
        instruments. This portfolio may also engage in transactions involving
        stock index futures contracts and options thereon, and transactions
        involving the future delivery of fixed-income securities ("Financial
        Futures Contracts") and options thereon as a hedge against changes in
        market conditions.

        The MULTI-ASSET PORTFOLIO seeks long-term total investment return
        consistent with moderate investment risk. This portfolio invests in
        growth equity securities, convertible securities, investment grade
        fixed-income securities and money market securities. This portfolio may
        also engage in transactions involving stock index futures contracts and
        options thereon, and Financial Futures Contracts and options thereon as
        a hedge against changes in market conditions.

        The HIGH YIELD PORTFOLIO seeks high current income. A secondary
        investment objective is capital appreciation. This portfolio invests at
        least 65% of its assets in high-yielding, high-risk, income-producing
        corporate bonds, which generally carry ratings lower than those assigned
        to investment grade bonds by Moody's Investors Service, Inc. ("Moody's")
        or Standard & Poor's Corporation ("S&P"), or which are unrated. This
        portfolio may also engage in transactions involving Financial Futures
        Contracts and options thereon as a hedge against changes in market
        conditions.

                          NOTES TO FINANCIAL STATEMENTS


1.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

        The FIXED INCOME PORTFOLIO seeks a high level of current income
        consistent with preservation of capital. This portfolio invests
        primarily in investment grade, fixed-income securities and may engage in
        Financial Futures Contracts and options thereon as a hedge against
        changes in market conditions.

        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 corporate debt securities rated Aa
        or better by Moody's or AA or better by S&P.

        The MONEY MARKET PORTFOLIO seeks current income consistent with
        stability of principal through investment in a diversified portfolio of
        money market instruments maturing in 397 days or less. The portfolio
        will maintain a dollar-weighted average portfolio maturity of not more
        than 90 days.

        Purchases and sales of shares of the portfolios of the Trust 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 Trust 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.

        The TARGET '98 PORTFOLIO is no longer available. This portfolio invested
        primarily in zero coupon securities and current, interest bearing,
        investment grade debt obligations which were issued by the U.S.
        Government, its agencies and instrumentalities, and both domestic and
        foreign corporations. These investments matured no later than November
        15, 1998. If the Company did not receive reallocation instructions from
        contractholders before November 15, 1998, Contract Values were
        automatically reallocated to the Money Market Portfolio.

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. There is a free withdrawal amount for
        the first withdrawal during a contract year after the first contract
        year. The free withdrawal amount is equal to 10% of aggregate purchase
        payments that remain subject to the withdrawal charge and that have not
        previously been withdrawn. 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 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:

                          NOTES TO FINANCIAL STATEMENTS


2.      CHARGES AND DEDUCTIONS (continued)

        ANNUITY CHARGE: Contractholders may elect a lump sum payment or one of
        three annuity options. Option 1 provides a life income with installments
        guaranteed, Option 2 provides a joint and survivor annuity, and Option 3
        provides income for a specified period. No annuity charge is assessed if
        Option 1 or Option 2 is elected. If a contractholder elects Option 3, an
        annuity charge equal to the withdrawal charge if the contract were
        surrendered may be applied. No annuity charge will be assessed if Option
        3 is elected by a beneficiary under the death benefit.

        RECORDS MAINTENANCE CHARGE: An annual records maintenance charge of $30
        is charged against each contract, which reimburses the Company for
        expenses incurred in establishing and maintaining records relating to a
        contract. For contracts issued prior to September 1, 1987, the records
        maintenance charge will be assessed on December 31 of each calendar
        year. The charge will be waived on contracts for which the contract
        value is totally surrendered during the year. For contracts issued on or
        after September 1, 1987, the records maintenance charge will be assessed
        on each anniversary of the issue date of the contract. In the event that
        a total surrender of contract value is made, the charge will be assessed
        as of the date of surrender without proration.

        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 or if a transfer is made within 30 days of the
        issue date of the contract.

        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, upon death of the contractholder or upon annuitization;
        however, it reserves the right to deduct any premium taxes when
        incurred. Premium taxes generally range from 0% to 3.5%.

                          NOTES TO FINANCIAL STATEMENTS


2.      CHARGES AND DEDUCTIONS (continued)

        MORTALITY AND EXPENSE RISK CHARGE: The Company deducts mortality and
        expense risk charges, which total to an annual rate of 1.25% of the net
        asset value of each portfolio, computed on a daily basis. The mortality
        risk charge is compensation for the mortality risks assumed by the
        Company from its contractual obligations to make annuity payments after
        the contract has annuitized for the life of the annuitant, to waive the
        withdrawal charge in the event of the death of the annuitant and to
        provide a death benefit if the annuitant dies prior to the date annuity
        payments begin. The expense risk charge is compensation for the risk
        assumed by the Company that the cost of administering the contracts will
        exceed the amount received from the records maintenance charge and the
        administrative expense charge. Both of these charges are guaranteed by
        the Company and cannot be increased.

        ADMINISTRATIVE EXPENSE CHARGE: The Company deducts an administrative
        expense charge at an annual rate of 0.15% of the net asset value of each
        portfolio, computed on a daily basis. The administrative expense charge
        is designed to cover those expenses which exceed the revenues from the
        records maintenance charge.

        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.
