                                    SUMMARY
- --------------------------------------------------------------------------------
 
     This Prospectus describes the uses and objectives of the Contracts, their
costs, and the rights and privileges of the Owner. It also contains information
about the Company, the Separate Account and its Divisions, and the Portfolios in
which the Divisions invest. We urge you to read it carefully and retain it and
the Prospectus for the Trust for future reference. (The Prospectus for the Trust
is attached to and follows this Prospectus).
 
WHAT IS THE CONTRACT?
 
   
     The Contract offered is a tax deferred annuity which provides fixed
benefits, variable benefits or a combination of both. Individuals wishing to
purchase a Contract must complete an application and provide an initial Purchase
Payment which will be sent to the Company at its Administrative Service Center
or in such other manner as deemed acceptable to the Company. The minimum and
maximum Purchase Payments vary depending upon the type of Contract purchased.
(See "Minimum Purchase Payment").
    
 
WHAT IS THE DIFFERENCE BETWEEN A VARIABLE ANNUITY AND A FIXED ANNUITY?
 
     The Contract has appropriate provisions relating to variable and fixed
accumulation values and variable and fixed annuity payments. A Variable Annuity
and a Fixed Annuity have certain similarities. Both provide that Purchase
Payments, less certain deductions, will be accumulated prior to the Annuity
Date. After the Annuity Date, annuity payments will be made to a designated
payee for the life of the Annuitant or a period certain or a combination
thereof. The Company assumes mortality and expense risks under the Contracts,
for which it receives certain compensation.
 
     The most significant difference between a Variable Annuity and a Fixed
Annuity is that under a Variable Annuity, all investment risk before and after
the Annuity Date is assumed by the Owner or other payee; the amounts of the
annuity payments vary with the investment performance of the Divisions of the
Separate Account selected by the Owner. Under a Fixed Annuity, in contrast, the
investment risk after the Annuity Date is assumed by the Company and the amounts
of the annuity payments do not vary.
 
HOW MAY PURCHASE PAYMENTS BE ALLOCATED?
 
     Purchase Payments for the Contracts may be allocated pursuant to
instructions in the application to one or more Divisions of the Separate
Account, and/or to the Company's General Account. The Separate Account invests
in shares of the following Portfolios (see "Anchor Series Trust"):
 
<TABLE>
<S>                                               <C>

     * GROWTH AND INCOME                          * MONEY MARKET
     * STRATEGIC MULTI-ASSET
</TABLE>
 
Purchase Payments allocated to the General Account will earn interest at the
current rate then being offered by the Company for a one year period beginning
on the date amounts are allocated to it.
 
     Prior to the Annuity Date, transfers may be made among the Divisions and/or
the General Account. Fifteen transfers are permitted before a transfer fee will
be assessed. (See "Description of the Contracts -- Transfer During Accumulation
Period").
 
MAY WITHDRAWALS BE MADE BEFORE ANNUITIZATION?
 
   
     Except as explained below, Contract Value may be withdrawn at any time
during the Accumulation Period. In addition to potential losses due to
investment risks, withdrawals may be reduced by a Withdrawal Charge, and a
penalty tax and income tax may apply. Contracts in connection with Qualified
Plans may be subject to additional withdrawal restrictions imposed by the plan.
Alternatively, there is a free withdrawal amount which applies to the first
withdrawal during a Contract Year after the first Contract Year. (See "Contract
Charges -- Sales Charges -- Withdrawal Charge"). Certain Owners of Nonqualified
Plan Contracts and Contracts issued in connection with Individual Retirement
Annuities ("IRAs") may choose to withdraw amounts which in the aggregate add up
to 10% of their Purchase Payments annually pursuant to a systematic withdrawal
program without charge. (See
    
 
                                        4
<PAGE>   9
 
"Purchases and Contract Value -- Systematic Withdrawal Program"). Withdrawals
are taxable and a 10% federal tax penalty may apply to withdrawals before age
59 1/2.
 
     Owners should consult their own tax counsel or other tax adviser regarding
any withdrawals or distributions.
 
CAN I EXAMINE THE CONTRACT?
 
     The Contract Owner may return the Contract to the Company within 10 days
(or longer period if required by state law) after it is received by delivering
or mailing it to the Company's Administrative Service Center. If the Contract is
returned to the Company, it will be terminated and, unless otherwise required by
state law, the Company will pay the Owner an amount equal to the Contract Value
represented by the Contract on the date it is received by the Company.
 
WHAT ARE THE CHARGES AND DEDUCTIONS UNDER A CONTRACT?
 
     A mortality and expense risk charge is assessed daily against the assets of
each Division at an annual rate of 1.25%. An administrative expense charge is
assessed daily against the assets of each Division at an annual rate of 0.15%.
The Contracts also provide for certain deductions and charges, including a
Records Maintenance Charge of $30 annually, which is guaranteed not to increase.
The Contract permits up to 15 free transfers each Contract Year, after which
point a $25 transfer fee ($10 in Texas and Pennsylvania) is applicable to each
subsequent transfer. Additionally, a Withdrawal Charge may be assessed against
the Contract Value during the first five Contribution Years (5%-4%-3%-2%-1%)
when a withdrawal is made. (See "Contract Charges").
 
DOES THE CONTRACT PAY ANY DEATH BENEFITS?
 
     A Death Benefit is provided in the event of the death of the Owner during
the Accumulation Period. The Death Benefit is equal to the greater of: (1) the
Contract Value upon receipt of Due Proof of Death; or (2) the total of Purchase
Payments made prior to the death of the Owner, minus any partial withdrawals
and/or partial annuitizations and contract charges, all accumulated annually at
5%; or (3) after the fifth Contract Year, the Contract Value at the last
anniversary of the Issue Date of the Contract minus any partial withdrawals
and/or partial annuitizations since that anniversary. (See "Description of the
Contracts -- Death Benefit").
 
WHAT ARE THE AVAILABLE ANNUITY OPTIONS UNDER THE CONTRACT?
 
     There are three available annuity options under the Contract. They include
an annuity for life, a joint and survivor annuity, and monthly payments for a
specified number of years. If a Contract Owner does not elect otherwise, monthly
annuity payments generally will be made under the first option to provide a life
annuity with 120 monthly payments certain. (See "Annuity Period -- Annuity
Options").
 
DOES THE OWNER HAVE ANY VOTING RIGHTS UNDER THE CONTRACT?
 
     Owners will have the right to vote on matters affecting the Portfolios to
the extent that proxies are solicited by the Trust. If the Owner does not vote,
the Company will vote such interests in the same proportion as it votes shares
for which it has received instructions. (See "Anchor Series Trust -- Voting
Rights").

                                  AND EXAMPLES
- --------------------------------------------------------------------------------
 
1.  The purpose of the foregoing tables and examples is to assist the Contract
    Owner in understanding the various costs and expenses that he or she will
    bear directly or indirectly. The table reflects expenses of the Separate
    Account as well as the Trust. For additional information see "Contract
    Charges" of this Prospectus and "Management of the Trust" of the Prospectus
    for the Trust. The examples do not illustrate the tax consequences of
    surrendering a Contract.
 
2.  The examples assume that there were no transactions which would result in
    the imposition of the Transfer Fee. Premium taxes are not reflected.
 
3.  For purposes of the amounts reported in the examples, the Records
    Maintenance Charge is reflected by dividing the total amount of Records
    Maintenance Charges anticipated to be collected during the year by the total
    net assets of the Separate Account's Divisions and the related Fixed Account
    assets.
 
4.  NEITHER THE FEE TABLES NOR THE EXAMPLES ARE REPRESENTATIONS OF PAST OR
    FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

                                PERFORMANCE DATA
- --------------------------------------------------------------------------------
 
     From time to time the Separate Account may advertise its Money Market
Division's "yield" and "effective yield." Both yield figures are based on
historical earnings and are not intended to indicate future performance. The
"yield" of the Money Market Division refers to the net income generated for a
Contract funded by an investment in the Division over a seven-day period (which
period will be stated in the advertisement). This income is then "annualized."
That is, the amount of income generated by the investment during that week is
assumed to be generated each week over a 52-week period and is shown as a
percentage of the investment. The "effective yield" is calculated similarly but,
when annualized, the income earned by an investment in the Division 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
Annuity Charges or 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 Divisions. 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 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 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
Division. The effect of applicable Withdrawal Charges due to the assumed
redemption will be reflected in the return figures, but may be omitted in
additional return figures given for comparison.
 
     For a more complete description of Contract charges, see "Contract
Charges"; for a more detailed description of the performance data computations,
please refer to the Statement of Additional Information.

                 DESCRIPTION OF ANCHOR NATIONAL LIFE INSURANCE
                        COMPANY AND THE SEPARATE ACCOUNT
- --------------------------------------------------------------------------------
 
COMPANY
 
     The Company is a stock life insurance company originally organized under
the laws of the state of California in April 1965. On January 1, 1996, the
Company redomesticated under the laws of the state of Arizona. The principal
business address of the Company is 1 SunAmerica Center, Los Angeles, California
90067-6022. The Company is an indirect, wholly owned subsidiary of SunAmerica
Inc., a Maryland corporation.
 
   
     The Company 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., Imperial
Premium Finance, Inc., Resources Trust Company and four broker-dealers,
specialize in retirement savings and investment products and services, including
fixed and variable annuities, mutual funds, premium finance, broker-dealer, and
trust administration services. The Company is admitted to conduct life insurance
and annuity business in the District of Columbia and in all states except New
York. It intends to market the Contract in all jurisdictions in which it is
admitted to conduct annuity business.
    
 
     The Company may from time to time publish in advertisements, sales
literature and reports to Owners, the ratings and other information assigned to
it by one or more independent rating organizations such as A.M. Best Company
("A.M. Best"), Moody's Investors Service, Inc. ("Moody's"), Standard & Poor's
Insurance Rating Services ("Standard & Poor's"), and Duff & Phelps. A.M. Best's
and Moody's ratings reflect their current opinion on the relative financial
strength and operating performance of an insurance company in comparison to the
norms of the life/health insurance industry. Standard & Poor's and Duff & Phelps
provide ratings which measure the claims-paying ability of insurance companies.
These ratings are opinions of an operating insurance company's financial
 
                                        9
<PAGE>   14
 
capacity to meet the obligations of its insurance policies in accordance with
their terms. Claims-paying ability ratings do not refer to an insurer's ability
to meet non-policy obligations (i.e., debt/commercial paper). These ratings do
not apply to the Separate Account. However, the contractual obligations under
the Contracts are the general corporate obligations of the Company.
 
     The Contracts offered by this Prospectus are issued by the Company and will
be funded in the Separate Account, as well as in the Company's General Account.
 
REINSURANCE OF PREVIOUSLY ISSUED CONTRACTS
 
     On November 13, 1989, SunAmerica Inc., the Company, 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, the Company 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, the
Company 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 the Company.
 
     Reinsured Contract Owners have the same contract rights and the same
contract values as they did before the reinsurance transaction. However, they
will look to the Company instead of to IR Life to fulfill the terms of their
Contracts. Pursuant to the reinsurance agreement, the Separate Account
originally held by IR Life with all of its assets was transferred to the
Company. Thus, as of the effective date of the reinsurance closing, the assets
of the Separate Account are only available to satisfy the Company's 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").
 
     The Stock Purchase Agreement, as amended, also provided for the sale of
Integrated Resources Asset Management Corp. ("IRAM") to SunAmerica Inc. Such
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. (See "Anchor Series Trust"). 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. ("SAAM").
 
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 the Company on January 18, 1990 and
reestablished under California insurance laws. In connection with the
redomestication of the Company, the establishment of the Separate Account was
ratified by the Company under Arizona insurance laws. The Separate Account is
registered with the Securities and Exchange Commission as a unit investment
trust under the Investment Company Act of 1940. This registration does not
involve supervision of the management of the Separate Account or the Company by
the Securities and Exchange Commission.
 
     On September 24, 1990, Variable Annuity Account One(c) ("Separate
Account(c)") was merged with and into the Separate Account. 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 reinsured to IR Life and, on January 18, 1990, reinsured to the Company. 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 Portfolios of the
Trust and by the General Account of the Company. The merger did not affect any
of the rights and obligations of the reinsured Capitol Contract Owners and the
Company under the reinsured Capitol Contracts or those of Contract Owners and
the Company under the Contracts. Nor did the merger affect those Owners'
Contract Values.
 
                                       10
<PAGE>   15
 
     The assets of the Separate Account are the property of the Company.
However, the assets of the Separate Account, equal to the reserves and other
contract liabilities of the Separate Account, are not chargeable with
liabilities arising out of any other business the Company may conduct. The
Company's obligations arising under the Contracts are general corporate
obligations of the Company.
 
     Income, gains and losses, whether or not realized, from assets allocated to
the Separate Account are credited to or charged against the Separate Account
without regard to other income, gains or losses of the Company.
 
     The Separate Account is divided into Divisions, with the assets of each
Division invested in the shares of one of the eleven Portfolios of the Trust.
The Company does not guarantee the investment performance of the Separate
Account or its Divisions. Values allocated to the Separate Account and the
amount of variable annuity payments will vary with the value of shares of the
Portfolios and the Contract charges. The Separate Account has also been
segmented into subaccounts which fund group annuity contracts issued by the
Company.

                              FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
 
     Financial statements of the Separate Account appear in the Statement of
Additional Information. Financial information regarding the General Account is
reported in the Company's financial statements. The Company's financial
statements are also included in the Statement of Additional Information. A copy
of the Statement of Additional Information may be obtained by contacting the
Company, c/o its Administrative Service Center.

                              ANCHOR SERIES TRUST
- --------------------------------------------------------------------------------
 
     Each of the eleven Divisions of the Separate Account invests solely in the
shares of one of the eleven Portfolios of the Trust. 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. Additional copies of this
Prospectus, the Trust's Prospectus and the Statement of Additional Information
can be obtained by calling the Administrative Service Center number on the cover
page of this Prospectus. Both Prospectuses should be read carefully before
investing to understand all aspects of the Contract, the Separate Account and
the Portfolios. SAAM, an affiliate of the Company, is the investment manager for
the Trust. Wellington Management Company, LLP ("WMC"), which is not affiliated
with the Company, serves as sub-adviser for the Trust. (See the Trust Prospectus
for information concerning the investment management fees.)
 
     The eleven Portfolios and their investment objectives are:
 
EQUITY PORTFOLIOS
 
     FOREIGN SECURITIES PORTFOLIO seeks long-term capital appreciation. This
Portfolio will invest primarily in a diversified group of equity securities
issued by foreign companies and primarily denominated in foreign currencies.
 
     CAPITAL APPRECIATION PORTFOLIO seeks long-term capital appreciation. This
Portfolio will invest 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.
 
   
     GROWTH PORTFOLIO seeks capital appreciation through investments in growth
equity securities. This Portfolio may engage in transactions involving stock
index futures and options thereon as a hedge against changes in market
conditions.
    
 
     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 will
invest primarily in equity securities of U.S. or foreign companies which are
expected to provide favorable returns in periods of rising inflation.
 
     GROWTH AND INCOME PORTFOLIO seeks high current income and long-term capital
appreciation. This Portfolio will invest primarily in securities that provide
the potential for growth and offer income, such as dividend-paying
 
                                       11
<PAGE>   16
 
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.
 
MANAGED PORTFOLIOS
 
     STRATEGIC MULTI-ASSET PORTFOLIO seeks high long-term total investment
return. This Portfolio will invest in a diversified group of securities of the
following types: growth equity and aggressive growth equity securities,
including the securities of smaller companies which may be newer and less
seasoned, investment grade and high-yield, high-risk bonds, international
securities and money market instruments. The 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.
 
     MULTI-ASSET PORTFOLIO seeks long-term total investment return consistent
with moderate investment risk. This Portfolio will invest in a diversified group
of securities, including: growth equity securities, convertible securities,
investment grade fixed income securities and money market securities. The
Portfolio also may 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.
 
FIXED INCOME PORTFOLIOS
 
     HIGH YIELD PORTFOLIO seeks high current income. A secondary investment
objective is capital appreciation. This Portfolio will seek its objectives by
investing, except for temporary defensive purposes, 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 or
Standard & Poor's, 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. High-yield, high-risk bonds
typically are subject to greater risks than are investments in lower-yielding,
higher-rated bonds. See the Trust's Prospectus for more information.
 
     FIXED INCOME PORTFOLIO seeks high level of current income consistent with
preservation of capital. This Portfolio will invest 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.
 
     GOVERNMENT AND QUALITY BOND PORTFOLIO seeks relatively high current income,
liquidity and security of principal. This Portfolio will invest 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 Standard & Poor's.
 
     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.
 
     There is no assurance that the investment objective of any of the
Portfolios will be met. 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 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 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.
 
CONTRACT OWNERS IN TARGET '98 PORTFOLIO
 
     As of January 1, 1998, no Purchase Payments or transfers into the Target
'98 Division are being accepted. Purchase Payments may be allocated among the
other eleven Divisions of the Separate Account and/or Fixed Account option.
 
     Contract Owners currently in the Target '98 Division must provide the
Company with reallocation instructions before November 15, 1998. If the Company
does not receive reallocation instructions before November 15, 1998,
 
                                       12
<PAGE>   17
 
Contract Values will be automatically reallocated to the Money Market Division.
Reallocations of Contract Values from the Target '98 Division will not be
considered "transfers" for purposes of determining any applicable transfer fees.
Other transfers out of the Target '98 Division will not be permitted after
October 15, 1998. None of the foregoing constraints affect a Contract Owner's
right to redeem his or her Contract Value at any time (See "Purchases and
Contract Value -- Withdrawals (Redemption)").
 
VOTING RIGHTS
 
     In accordance with its view of present applicable law, the Company will
vote the shares of the Trust held in the Separate Account at special meetings of
the shareholders of the Trust in accordance with instructions received from
persons having the voting interest in the Separate Account. The Company will
vote shares for which it has not received instructions in the same proportion as
it votes shares for which it has received instructions. The Trust does not hold
regular meetings of shareholders.
 
     The number of shares which a person has a right to vote will be determined
as of a date to be chosen by the Company not more than 60 days prior to the
meeting of the Trust's shareholders. Voting instructions will be solicited by
written communication at least 14 days prior to such meeting. The person having
such voting rights will be the Contract Owner before the Annuity Date or the
death of the Annuitant; thereafter the payee entitled to receive payments under
the Contract. Voting rights attributable to a Contract will generally decrease
as Contract Values decrease.
 
SUBSTITUTION OF SECURITIES
 
     If the shares of any of the Portfolios should no longer be available for
investment by the Separate Account or if, in the judgment of the Company's Board
of Directors, further investment in the shares of a Portfolio is no longer
appropriate in view of the purpose of the Contract, the Company may substitute
shares of another open-end management investment company (or series thereof) for
Portfolio shares already purchased or to be purchased in the future by Purchase
Payments under the Contract. No substitution of securities may take place
without prior approval of the Securities and Exchange Commission and under such
requirements as it may impose.

                                CONTRACT CHARGES
- --------------------------------------------------------------------------------
 
MORTALITY AND EXPENSE RISK CHARGE
 
     The Company deducts a risk charge from each Division of the Separate
Account during each Valuation Period. The risk charge is equal, on an annual
basis, to 1.25% of the daily net asset value of each Division (approximately
 .90% is for mortality risks and approximately .35% is for expense risks). The
mortality risks assumed by the Company arise from its contractual obligations to
make annuity payments after the Annuity Date for the life of the Annuitant(s),
to waive the Withdrawal Charge in the event of the death of the Annuitant, and
to provide the death benefit prior to the Annuity Date. The expense risk assumed
by the Company is that the costs of administering the Contracts and the Separate
Account will exceed the amount received from the Records Maintenance Charge and
the Administrative Expense Charge. (See "Administrative Charges"). This charge
is guaranteed by the Company and cannot be increased.
 
ADMINISTRATIVE CHARGES
 
     ADMINISTRATIVE EXPENSE CHARGE
 
     The Company deducts an Administrative Expense Charge from each Division of
the Separate Account which is equal, on an annual basis, to .15% of the daily
net asset value of each Division. This charge is designed to cover those
administrative expenses which exceed the revenues from the Records Maintenance
Charge. The Company does not intend to profit from this charge. The Company
believes that the Administrative Expense Charge has been set at a level that
will recover no more than the actual costs associated with administering the
Contract. In the event that it exceeds the amount necessary to reimburse the
Company for its administrative expenses the charge will be appropriately
reduced. In no event will this charge be increased. The Administrative Expense
Charge is assessed during both the Accumulation Period and the Annuity Period.
 
                                       13
<PAGE>   18
 
     RECORDS MAINTENANCE CHARGE
 
     An annual Records Maintenance Charge of $30 is charged against each
Contract. The amount of this charge is guaranteed and cannot be increased by the
Company. This charge 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 for such Contracts during the year in which Contract Value is totally
surrendered.
 
     For Contracts issued on or after September 1, 1987, the Records Maintenance
Charge will be assessed each Contract Year on the 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.
 
SALES CHARGES
 
     The Withdrawal Charge and the Annuity Charge are sales charges.
 
     WITHDRAWAL CHARGE
 
     Effective January 1, 1989, federal tax law limits withdrawals from annuity
contracts issued in connection with 403(b) Qualified Plans. Subject to those
limitations, the Contract Value may be withdrawn at any time during the
Accumulation Period. Contract Owners should consult their own tax counsel or
other tax adviser regarding any withdrawals. (See "Taxes -- Tax Treatment of
Withdrawals -- Non-Qualified Contracts" and "Taxes -- Tax Treatment of
Withdrawals -- Qualified Contracts").
 
     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 10% of the aggregate Purchase Payments less prior withdrawals.
Alternatively, certain Owners of Non-Qualified Contracts and Contracts issued in
connection with IRAs may choose to withdraw amounts which in the aggregate add
up to 10% of their initial Purchase Payments annually pursuant to the Systematic
Withdrawal Program 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").
 
     A contingent deferred sales charge, which is referred to as the Withdrawal
Charge, may be imposed upon other withdrawals. Withdrawal Charges will vary in
amount depending upon the Contribution Year in which the Purchase Payment being
withdrawn was made, and will be calculated based on the Withdrawal Charge Table,
below, and the amount of Purchase Payment withdrawn which is still subject to
the Withdrawal Charge and not previously withdrawn. The Withdrawal Charge is
deducted from 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. Free withdrawals and other withdrawals will be allocated to
Purchase Payments on a first-in-first-out basis so that all withdrawals are
allocated to Purchase Payments to which the lowest Withdrawal Charge, if any,
applies.

     Where legally permitted, the Withdrawal Charge will be eliminated when a
Contract is issued to an officer, director or employee of the Company or its
affiliates, or an immediate family member of such person. In addition, the
Withdrawal Charge may be waived by the Company on withdrawals where the amount
withdrawn is used to
 
                                       14
<PAGE>   19
 
purchase another annuity contract issued by the Company. Additional information
regarding the elimination or waiver of the Withdrawal Charge may be obtained by
contacting the Company.
 
     The amounts obtained from the Withdrawal Charge will be used to pay sales
commissions and other promotional or distribution expenses associated with the
marketing of the Contracts. To the extent that the Withdrawal Charge is
insufficient to cover all sales commissions and other promotional or
distribution expenses, the Company may use any of its corporate assets,
including potential profit which may arise from the Mortality and Expense Risk
Charge, (See "Contract Charges -- Mortality and Expense Risk Charge"), to make
up any difference.
 
     ANNUITY CHARGE
 
     If a Contract Owner elects to have annuity payments made under annuity
option 1, Life Income with Installments Guaranteed or annuity option 2, Joint
and Survivor Annuity (See "Annuity Period -- Annuity Options"), no Annuity
Charge applies and 100% of Contract Value, less any premium tax, is applied.
 
     If a Contract Owner elects annuity option 3, Income for a Specified Period,
and if Purchase Payments were made in the Contract Year in which annuity
payments are to begin or any of the four preceding Contract Years, an Annuity
Charge may apply. This Annuity Charge equals the Withdrawal Charge that would
apply if the Contract were being surrendered. Further, no Annuity Charge will be
assessed if annuity option 3 is elected by a Beneficiary under the Death
Benefit.
 
     The Annuity Charge also applies to certain annuitizations of Contract
Values allocated to the General Account.
 
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 of surrender or when annuity payments begin. The Company currently intends
to deduct premium taxes at the time of surrender, upon death of the Owner or
upon annuitization; however, it reserves the right to deduct premium taxes when
incurred. Premium taxes generally range from 0% to 3.5%.
 
DEDUCTION FOR SEPARATE ACCOUNT INCOME TAXES
 
     While the Company is not currently maintaining a provision for taxes, the
Company 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. The Company will deduct for any
taxes incurred by it as a result of the operation of the Separate Account
whether or not there was a provision for taxes and whether or not it was
sufficient. (See "Taxes").
 
OTHER EXPENSES
 
     There are other deductions from and expenses paid out of the assets of the
Trust which are described in the accompanying Trust Prospectus.
 
   
WAIVER OR REDUCTION OF CHARGES, CREDITS OR BONUS GUARANTEED INTEREST RATES FOR
SALES TO CERTAIN GROUPS
    
 
   
     The Company may reduce or waive some of the charges, credit additional
amounts or grant bonus guaranteed interest rates on individual Contracts sold to
certain groups of individuals, or to a trustee, employer or other entity
representing a group, where it is expected that such sales will result in
savings of sales or administrative expenses. The Company determines the
eligibility of groups for such reduced or waived charges, and the amount of such
reductions for particular groups, by considering the following factors: (1) the
size of the group; (2) the total amount of Purchase Payments expected to be
received from the group; (3) the nature of the group for which the Contracts are
purchased, and the persistency expected in that group; (4) the purpose for which
the Contracts are purchased and whether that purpose makes it likely that
expenses will be reduced; and (5) any other circumstances which the Company
believes to be relevant to determining whether reduced sales or administrative
expenses may be expected. None of the reductions in charges for group sales is
contractually guaranteed.
    
 
   
     In addition, the Company may waive or reduce the Records Maintenance Charge
or Administrative Expense Charge, credit additional amounts or grant bonus
guaranteed interest rates in connection with Contracts sold to
    
 
                                       15
<PAGE>   20
 
   
officers, directors and employees of the company or its affiliates, registered
representatives and employees of broker/dealers with a current selling agreement
with the company ("Eligible Individuals") and certain family members of Eligible
Individuals. Such reductions, waivers or interest crediting arrangements may be
withdrawn or modified by the Company on a uniform basis. The Company's
reductions in charges for group sales will not be unfairly discriminatory to the
interests of any Contract Owners. Commissions may be waived or reduced with
respect to contracts established for the personal accounts of Eligible
Individuals.

                          DESCRIPTION OF THE CONTRACTS
- --------------------------------------------------------------------------------
 
TRANSFER DURING ACCUMULATION PERIOD
 
     During the Accumulation Period, the Contract Owner, or his or her agent,
may transfer Contract Values among Divisions and/or the General Account, by
written request or by telephone authorization. Telephone transfers are
automatically accepted unless the Contract Owner elects to not permit telephone
transfers on the Contract application or the Company is otherwise instructed by
the Contract Owner. The Company has in place procedures which are designed to
provide reasonable assurance that telephone authorizations are genuine,
including tape recording all telephone communications and requesting identifying
information. Accordingly, the Company and its affiliates disclaim all liability
for any claim, loss or expense resulting from any alleged error or mistake in
connection with a telephone transfer which was not properly authorized by the
Contract Owner. However, if the Company fails to employ reasonable procedures to
ensure that all telephone transfers are properly authorized, the Company may be
held liable for such losses. The Company reserves the right to modify or
discontinue at any time and without notice the use of telephone transfers and
acceptance of telephone transfers from someone other than the Contract Owner.
Telephone calls authorizing transfers must be completed by 4:00 p.m. Eastern
time in order to effect the transfer the day of receipt. All other transfers
will be processed on the next business day.
 
     Transactions effecting transfer may not be made more than fifteen times in
any Contract Year without charge. A charge of $25 per transaction is assessed
($10 in Texas and Pennsylvania) against any transaction effecting transfer in
excess of the fifteen permitted without charge in any Contract Year or, if all
or part of a Contract Owner's interest in a Division is transferred to another
Division, within 30 days of the Issue Date. Transfers made under the Dollar Cost
Averaging Program, described below, are counted against this limitation in the
same manner as other transfers. The fee will be deducted from Contract Values
which remain in the Division from which the transfer was made. If the remaining
Contract Value is insufficient to pay the transfer fee, then the fee will be
deducted from transferred Contract Values. The transfer fee is at cost with no
margin included for profit. The transfer fee may be waived, under certain
circumstances, in connection with pre-approved transfer programs.
 
     This transfer privilege may be suspended, modified or terminated at any
time without notice. (See "Taxes -- Diversification").
 
     The minimum partial transfer amount is $500. No partial transfer may be
made if the value of the Contract Owner's interest in the Division from which a
transfer is being made would be less than $500 after the transfer. As with
initial Purchase Payments, at least $500 must be allocated to a Division before
another Division is selected. These dollar amounts are subject to change at the
Company's option. The Company may waive the minimum partial transfer amount in
connection with pre-authorized automatic transfer programs.
 
     Any amounts allocated or transferred to the General Account may only be
transferred from the General Account once each Contract Year during the 30-day
period following the anniversary of such allocation or transfer. If a transfer
request is received prior to the anniversary of an allocation or transfer, then
the transfer will take effect on the next Valuation Date following the
anniversary if the anniversary is not a Valuation Date. If the Company receives
the transfer request within the 30 days following the anniversary of an
allocation or transfer to the General Account, the transfer will be effective on
the next following Valuation Date. The foregoing limitations may be waived in
connection with pre-authorized automatic transfer programs.
 
AUTOMATIC DOLLAR COST AVERAGING PROGRAM
 
     Contract Owners who wish to purchase units of the Separate Accounts over a
period of time may be able to do so through the Dollar Cost Averaging ("DCA")
Program. Under this DCA Program, a Contract Owner may authorize the automatic
transfer of a fixed dollar amount ($100 minimum) or percentage of his or her
choice at
 
                                       16
<PAGE>   21
 
regular intervals from either the Money Market Portfolio, Government and Quality
Bond Portfolio or the General Account to one or more of the Separate Accounts
(other than the Money Market Portfolio or the Government and Quality Bond
Portfolio) at the unit values determined on the dates of the transfers. The
intervals between transfers from the Money Market Portfolio or Government and
Quality Bond Portfolio may be monthly, quarterly, semi-annually or annually, at
the option of the Contract Owner. Transfers from the General Account must be
made by percentage and at quarterly intervals only and are limited to 8% of the
value of the Contract Owner's interest in the General Account in any Contract
Year. The theory of dollar cost averaging is that greater numbers of units are
purchased at times when the unit prices are relatively low than are purchased
when the prices are higher. This has the effect of reducing the aggregate
average cost per unit to less than the average of the unit prices on the same
purchase dates. However, participation in the DCA Program does not assure the
Contract Owner of a greater profit, or any profit, from his or her purchases
under the DCA Program; nor will it prevent or necessarily alleviate losses in a
declining market.
 
     Although the various options under the DCA Program will allow transfers to
be made either from the Money Market Portfolio, Government and Quality Bond
Portfolio or the General Account, a Contract Owner must elect to have the
transfers made exclusively from one or the other of these three sources. A
Contract Owner may elect to increase, decrease or change the frequency or amount
of Purchase Payments under a DCA Program. The application and any Purchase
Payments should be sent to the Company, c/o its Administrative Service Center
for correspondence accompanied by payments. The Company reserves the right to
modify, suspend or terminate the DCA Program at any time.
 
     A Contract Owner may not simultaneously participate in both the DCA Program
and the Systematic Withdrawal Program. Participation in the DCA Program will be
effective one week after the Company has received and approved the application
to participate in the DCA Program.
 
MODIFICATION OF THE CONTRACT
 
     Only the Company's President or Secretary may approve a change or waive the
provisions of the Contract. Any change or waiver must be in writing. No agent
has the authority to change or waive the provisions of the Contract.
 
ASSIGNMENT
 
     Contracts issued pursuant to Non-Qualified Plans that are not subject to
Title I 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. The Company will not be bound by any assignment until written
notice is received by the Company, c/o its Administrative Service Center. The
Company is not responsible for the validity, tax or other legal consequences, of
any assignment. An assignment will not affect any payments the Company may make
or actions it may take before it receives notice of the assignment.
 
     If the Contract is issued pursuant to a Qualified Plan (or a Non-Qualified
Plan that is subject to Title I 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, CONTRACT OWNERS SHOULD
CONSULT COMPETENT TAX ADVISERS SHOULD THEY WISH TO ASSIGN THEIR CONTRACTS.
 
DEATH OF OWNER OF NON-QUALIFIED CONTRACT
 
     The following section applies only if the Contract is issued on a
Non-Qualified basis and if either of the two following conditions exists:
 
          (A) The Owner and the Annuitant are the same individual and that
     individual dies during the Accumulation Period; or
 
          (B) The Owner and Annuitant are different persons and the Owner dies
     during the Accumulation Period prior to the Annuitant's death.
 
     If either of the above conditions occurs, the following provisions apply:
 
          (1) If the Beneficiary is the spouse of the Owner, then the
     Beneficiary may elect to become the Owner and maintain the Contract in full
     force and effect. A spouse Beneficiary may alternatively choose to take a
     lump sum distribution. (See below).
                                       17
<PAGE>   22
 
          (2) If the Beneficiary is a natural person and not the spouse of the
     Owner, the Beneficiary can elect to have the existing Contract Value paid
     under one of the annuity options set forth in the Contract over a period
     not extending beyond the life expectancy of the Beneficiary at the time of
     the election, or such a Beneficiary can elect to take a lump sum
     distribution. (See below). Payments under any annuity option selected must
     begin not later than one year after the date of death of the Owner.
 
          (3) If there is no Beneficiary or if the Beneficiary is not a natural
     person, then the entire Contract Value must be paid out within five years
     of the Owner's death.
 
     The amount of a lump sum distribution is the greater of:
 
          (1) the current Contract Value at the time of election; or
 
          (2) the total amount of Purchase Payments made under the Contract less
     the aggregate dollar amount of any partial withdrawals and any Withdrawal
     Charges which were assessed at the time of withdrawal. Under this
     alternative election, the lump sum must be paid to the Beneficiary within
     five years of the Owner's death.
 
     If the Contract is issued pursuant to a Qualified Plan, similar provisions
will apply upon the death of the Contract Owner. Purchasers acquiring Contracts
pursuant to Qualified Plans should consult a qualified pension or tax adviser.
 
DEATH BENEFIT
 
     If the Annuitant dies during the Accumulation Period, a Death Benefit will
be payable to the Beneficiary upon receipt by the Company of Due Proof of Death
of the Annuitant.
 
     The Death Benefit is equal to the greater of:
 
          (1) the Contract Value at the end of the Valuation Period during which
     Due Proof of Death and an election of the type of payment to the
     Beneficiary is received by the Company, c/o its Administrative Service
     Center; or
 
          (2) the total dollar amount of Purchase Payments minus:
 
             (a) any partial withdrawals;
 
             (b) all Contract Owner transaction expenses deducted during the
        term of the Contract prior to the date of death; and
 
             (c) any partial annuitizations,
 
        all accumulated annually at 5% at the date of death; or
 
          (3) after the fifth Contract Year, the Contract Value at the last
     anniversary of the Issue Date of the Contract minus the total dollar amount
     of partial withdrawals and/or partial annuitizations made since that
     anniversary.
 
     Payment of the Death Benefit may be made in one lump sum or applied under
one of the annuity options.
 
BENEFICIARY
 
     The Contract Owner may designate the Beneficiary(ies) to receive any amount
payable on death. However, where a Contract is jointly owned, each joint Owner
shall be a primary Beneficiary. The original Beneficiary(ies) will be named in
the application. Unless an irrevocable Beneficiary(ies) designation was
previously filed or unless the Contract is jointly owned, the Contract Owner may
change the Beneficiary(ies) prior to the Annuity Date by written request
delivered to the Company, c/o its Administrative Service Center, or by
completing a Change of Beneficiary Form provided by the Company. Any change will
take effect when recorded by the Company. The Company is not liable for any
payment made or action taken before it records the change.
 
- --------------------------------------------------------------------------------
 
                                 ANNUITY PERIOD
- --------------------------------------------------------------------------------
 
ANNUITY DATE
 
     The Contract Owner selects an Annuity Date (the date on which annuity
payments are to begin) at the time of application. The Annuity Date must always
be the first day of a calendar month and must be at least one month after
 
                                       18
<PAGE>   23
 
the Issue Date. Annuity payments will begin no later than the first day of the
calendar month following the Annuitant's 85th birthday. Where joint Annuitants
are named, the Annuity Date may not be later than the first of the month
following the 85th birthday of the youngest Annuitant. The Contract Owner may
change the Annuity Date at any time at least seven days prior to the Annuity
Date then indicated on the Company's records by written notice to the Company,
c/o its Administrative Service Center.
 
     The actual dollar amount of variable annuity payments is dependent upon:
(1) the Contract Value at the time of annuitization; (2) the annuity table
specified in the Contract; (3) the annuity option selected; and (4) the
investment performance of the Divisions selected. In addition, if annuity option
3, Income for a Specified Period, is elected, an Annuity Charge may apply. (See
"Contract Charges -- Sales Charges" and "Contract Charges -- Annuity Charge").
 
     The annuity tables contained in the Contract are based on a 5% assumed
investment rate. If the actual net investment rate exceeds 5%, payments will
increase. Conversely, if the actual rate is less than 5%, annuity payments will
decrease. If a higher assumed investment rate were used, the initial payment
would be higher, but the actual net investment rate would have to be higher in
order for annuity payments to increase.
 
     The Annuitant receives the value of a fixed number of Annuity Units each
month. The value of a fixed number of Annuity Units will reflect the investment
performance of the Divisions elected, and the amount of each annuity payment
will vary accordingly.
 
ALLOCATION OF ANNUITY PAYMENTS
 
     If all of the Contract Value on the seventh calendar day before the Annuity
Date is allocated to the General Account, the Annuity will be paid as a fixed
annuity. If all of the Contract Value on that date is allocated to the Separate
Account, the Annuity will be paid as a Variable Annuity. If the Contract Value
on that date is allocated to both the General Account and the Separate Account,
the Annuity will be paid as a combination of a fixed annuity and a Variable
Annuity to reflect the allocation between the accounts. Variable Annuity
payments will reflect the investment performance of the Separate Account
Divisions. The payee(s) may, by written notice to the Company, convert Variable
Annuity payments to fixed annuity payments. However, fixed annuity payments may
not be converted to Variable Annuity payments.
 
ANNUITY OPTIONS
 
     The Contract Owner, or any Beneficiary who is so entitled, may elect to
receive a lump sum at the end of the Accumulation Period. However, a lump sum
distribution may be deemed to be a withdrawal, and at least a portion of it may
be subject to federal income tax. (See "Taxes -- Tax Treatment of
Withdrawals -- Non-Qualified Contracts" and "Tax Treatment of
Withdrawals -- Qualified Contracts"). Alternatively, an annuity option may be
elected. The Contract Owner may elect an annuity option or change an annuity
option at any time during the lifetime of the Annuitant prior to the Annuity
Date. The Annuitant may make the election on the Annuity Date unless the
Contract Owner has restricted the right to make such an election. The
Beneficiary may elect an annuity option upon the Annuitant's death unless the
Contract Owner has restricted this right.
 
     If no other annuity option is elected, monthly annuity payments will be
made in accordance with annuity option 1 below with a 10 year period certain.
Generally, annuity payments will be made in monthly installments. However, if
the amount available to apply under an annuity option is less than $5,000, and
state law permits, the Company has the right to pay the annuity in one lump sum.
In addition, if the first payment provided would be less than $50, and state law
permits, the Company shall have the right to change the frequency of payments to
be at quarterly, semi-annual or annual intervals so as to result in an initial
payment of at least $50.
 
     Contract Owners may elect to have annuity payments electronically wired to
his or her financial institution by completing the instructions on the
Electronic Fund Transfer Form or by written request delivered to the Company at
its Administrative Service Center. A voided check (for checking accounts), the
account number and bank ABA number must accompany all requests. Electronic
transfers may also be requested on the Annuity Option Selection Form. The
Company reserves the right to modify, suspend or terminate the availability of
electronic fund transfers at any time.
 
     The following annuity options are generally available under the Contract.
However, there may be restrictions in the retirement plan pursuant to which a
Contract issued on a qualified basis has been purchased.
 
                                       19
<PAGE>   24
 
OPTION 1 -- LIFE INCOME WITH INSTALLMENTS GUARANTEED
 
     An annuity payable monthly during the lifetime of the payee. Upon election
a guaranteed payment period of either 10 years or 20 years may be chosen. If the
payee dies before the end of the guaranteed period, the present value, based on
a 5% annual interest rate, of any remaining guaranteed payments will be paid to
the payee's estate or to the Beneficiary.
 
OPTION 2 -- JOINT AND SURVIVOR ANNUITY
 
     An annuity payable monthly while both payees are living. Upon the death of
either payee, the monthly income payable will continue during the lifetime of
the surviving payee at the percentage of the full amount chosen at the time of
election of this annuity option. This is the automatic form of annuity where
joint Annuitants are named, but a different option may be elected.
 
     Annuity payments terminate automatically and immediately upon the death of
the surviving payee without regard to the number or total amount of payments
received.
 
     There is no minimum number of guaranteed payments and it is possible to
have only one annuity payment if both payees die before the due date of the
second payment.
 
     No Annuity Charge applies if either option 1 or option 2 is elected.
 
OPTION 3 -- INCOME FOR A SPECIFIED PERIOD
 
     If Purchase Payments were made in the Contract Year in which annuity
payments are to begin or in any of the four preceding Contract Years, an Annuity
Charge may apply. The Annuity Charge equals the Withdrawal Charge that would
apply if the Contract were being surrendered. No Annuity Charge will be assessed
if annuity option 3 is elected by a Beneficiary under the Death Benefit.
 
     Under this option, a payee can elect an annuity payable monthly for any
period of years from 5 to 30. This election must be made for full 12 month
periods. In the event the payee dies before the specified number of payments has
been made, the Beneficiary may elect to continue receiving the scheduled
payments or may alternatively elect to receive the present value, based on a 5%
annual interest rate, of any remaining guaranteed payments. Because Contract
Values are redeemable even after the Annuity Date under this option at any time
while payments are being made, the payee may elect to receive the present value
of the remaining payments, commuted at the interest rate used to create the
annuity factor for this option.
 
     The value of an Annuity Unit, regardless of the option chosen, takes into
account the Mortality and Expense Risk Charge. (See "Contract
Charges -- Mortality and Expense Risk Charge"). Since annuity option 3, Income
for a Specified Period, does not contain an element of mortality risk, the payee
is not getting the benefit of this Charge. There shall be no right to terminate
the Contract during the Annuity Period if the option elected contains an element
of mortality risk.
 
OTHER OPTIONS
 
     At the sole discretion of the Company, other annuity options may be made
available to the Contract Owner. However, to the extent that Withdrawal Charges
would otherwise apply to a withdrawal or termination, the identical Withdrawal
Charge may apply with respect to any additional options.
 
     With respect to Contracts issued under Sections 401, 403(b) or 408 of the
Code, any payments will be made only to the Annuitant and the Annuitant's
spouse.
 
TRANSFER DURING ANNUITY PERIOD
 
     During the Annuity Period, the payee has the sole right to transfer the
Contract Value to the General Account and/or among Separate Account Divisions by
written request to the Company. The following limitations apply:
 
          (1)  No transfer to a Separate Account Division may be made during the
     first year of the Annuity Period. Thereafter, only one transfer per
     Division is permitted during each Contract Year of the Annuity Period.
 
          (2)  The entire value in a Separate Account Division must be
     transferred.
 
                                       20
<PAGE>   25
 
          (3)  The request for transfer must be received by the Company, c/o its
     Administrative Service Center, during the 45 days preceding the anniversary
     of the Contract's Issue Date. The transfer will be effected at the next
     Annuity Unit value calculation after receipt of a valid transfer request
     which meets the limitations and conditions as are prescribed for transfers
     during the Accumulation Period. (See "Transfer During Accumulation
     Period").
 
          (4)  The amount allocated to the General Account in the event of a
     transfer from a Separate Account Division will be equal to the annuity
     reserve for the payee's interest in that Separate Account Division. The
     annuity reserve is the product of "(A)" multiplied by "(B)" multiplied by
     "(C)", where "(A)" is the number of Annuity Units representing the payee's
     interest in the Separate Account Division per annuity payment; "(B)" is the
     Annuity Unit value for the Separate Account Division; and "(C)" is the
     present value of $1.00 per payment period as of the adjusted age of the
     payee attained at the time of transfer, determined by using the 1983 Table
     A, projected at Scale G with interest at the rate of 5% per annum. Amounts
     transferred to the General Account will be applied under the annuity option
     originally elected, except that adjustment will be made for the time
     elapsed since the Annuity Date. All amounts and Annuity Unit values will be
     determined as of the end of the Valuation Period preceding the effective
     date of transfer.
 
          (5) The transfer privilege may be suspended or discontinued at any
     time.
 
DEATH BENEFIT DURING ANNUITY PERIOD
 
     If the payee dies after the Annuity Date while the Contract is in force,
the death proceeds, if any, will depend upon the annuity option in effect at the
time of the payee's death. If the Owner or Annuitant, if different, dies after
the Annuity Date and before the entire interest in the Contract has been
distributed, the remaining interest, if any, as provided for in the annuity
option elected will be distributed at least as rapidly as under the method of
distribution in effect at the Owner's or Annuitant's death.

                          PURCHASES AND CONTRACT VALUE
- --------------------------------------------------------------------------------
 
MINIMUM PURCHASE PAYMENT
 
     The minimum initial Purchase Payment for Contracts issued pursuant to a
Non-Qualified Plan is $1,000. Minimum additional Purchase Payments may be made
in amounts of $500. The minimum Purchase Payment for a Contract issued pursuant
to a Qualified Plan is $100. A minimum of $500 must be allocated to one Division
or the General Account before transfers are permitted. (See "Description of the
Contracts -- Transfer During Accumulation Period"). The Company reserves the
right to refuse any Purchase Payment at any time.
 
MAXIMUM PURCHASE PAYMENT
 
     Purchase Payments of more than $1,000,000 require prior Company approval.
 
ALLOCATION OF PURCHASE PAYMENTS
 
   
     Purchase Payments are allocated to the General Account and/or the
Division(s) of the Separate Account selected by the Contract Owner. The current
General Account allocation option pays a fixed rate of interest declared by the
Company for one year from the date amounts are allocated to it. The Company, at
its discretion, may offer other General Account allocation options which are
subject to different terms and conditions than apply to the current option.
    
 
     Contract Owners making initial Purchase Payments should be sure to specify
their allocations on the application for a Contract. If the application is in
good order, the Company will apply the initial Purchase Payment to the General
Account and the selected Division(s), and credit the Contract with Accumulation
Units within two business days of receipt at the P.O. Box for the Company's
Administrative Service Center. The number of Accumulation Units in a Division
attributable to a Purchase Payment is determined by dividing that portion of the
Purchase Payment which is allocated to the Division by the Division's
Accumulation Unit value during the Valuation Period when the allocation occurs.
 
                                       21
<PAGE>   26
 
     IF THE APPLICATION DOES NOT SPECIFY AN ALLOCATION, THE APPLICATION IS NOT
IN GOOD ORDER.
 
     If the application for a Contract is not in good order, the Company will
attempt to rectify it within five business days of its receipt at the P.O. Box
for the Company's Administrative Service Center. The Company will credit the
initial Purchase Payment within two business days after the application has been
rectified. Unless the Contract Owner consents otherwise, the application and the
initial Purchase Payment will be returned if the application cannot be put in
good order within five business days of its receipt.
 
     Just like Contract Owners making initial Purchase Payments, Contract Owners
making subsequent Purchase Payments should be sure to specify how they want
their payments allocated. OTHERWISE, THE COMPANY WILL AUTOMATICALLY PROCESS THE
PURCHASE PAYMENT BASED ON THE PREVIOUS ALLOCATION.
 
     A Contract Owner may elect to increase, decrease or change the frequency or
amount of Purchase Payments. The application and any Purchase Payments should be
sent to the Company at its Administrative Service Center.
 
ACCUMULATION UNIT VALUE
 
     Accumulation Unit value is determined Monday through Friday (except for the
following Federal holidays) as of 4:00 p.m. New York time.
 
   
<TABLE>
<S>                        <C>

  Memorial Day
</TABLE>
    
 
     A separate Accumulation Unit value is determined for each Division. If the
Company elects or is required to assess a charge for taxes, a separate
Accumulation Unit value may be calculated for Non-Qualified and Qualified
Contracts within each Division.
 
     The net assets are determined by calculating the total value of each
Division's assets (that is, the aggregate value of the shares of the Portfolio
of the Trust held by the Division). After calculation of the net assets of a
Division, that amount is reduced by the accrued but unpaid daily charge for
mortality and expense risks and administration expense (which together amount to
1.40% per annum) and any provision for taxes which may occur. After that
calculation, the resulting number is then divided by the number of Accumulation
Units outstanding at the end of the Valuation Period to determine Accumulation
Unit value.
 
     The Accumulation Unit value for each Division will vary with the price of a
share in the underlying Portfolio and in accordance with the Mortality and
Expense Risk Charge, Administrative Expense Charge, and any provision for taxes.
Assessments of premium tax, Withdrawal Charges and Records Maintenance Charges
are made separately for each Contract. They do not affect Accumulation Unit
value.
 
DISTRIBUTION OF CONTRACTS
 
     Contracts are sold by registered representatives of broker-dealers who are
licensed insurance agents of the Company, either individually or through an
incorporated insurance agency. Commissions paid to registered representatives
may vary, but in the aggregate are not anticipated to exceed 5% of any Purchase
Payment. In addition, under certain circumstances, certain sellers of the
Contracts may be paid persistency bonuses which will take into account, among
other things, the length of time Purchase Payments have been held under a
Contract and Contract Values. A persistency bonus is not anticipated to exceed
 .20%, on an annual basis, of the Contract Values considered in connection with
the bonus.
 
   
     Furthermore, the Company may from time to time, pay or allow additional
promotional incentives in the form of cash or other compensation. In some
instances, such other incentives may be offered only to certain broker/dealers
that sell or are expected to sell, during specified time periods, certain
minimum amounts of the Contract, or other contracts offered by the Company. In
addition, commissions may be waived or reduced in connection with certain
transactions. (See "Contract Charges -- Wavier or Reduction of Charges, Credits
or Bonus Guaranteed Interest Rates for Sales to Certain Groups").

WITHDRAWALS (REDEMPTIONS)
 
     Except as explained below, the Contract Owner may redeem a Contract for all
or a portion of the Contract Value during the Accumulation Period. The Contract
Owner may also redeem Contract Values after the Annuity Date if annuity option 3
is elected. Withdrawal Charges may be assessed. (See "Contract
Charges -- Withdrawal Charge").
 
     Effective January 1, 1989, withdrawals of amounts attributable to
contributions made pursuant to a salary reduction agreement (as defined in
Section 403(b)(11) of the Code) are limited to circumstances only: when the
Contract Owner attains age 59 1/2, separates from service, dies, becomes
disabled (within the meaning of Section 72(m)(7) of the Code), or in the case of
hardship. Withdrawals for hardship are restricted to the portion of the Contract
Owner's Contract Value which represents contributions made by the Contract Owner
and does not include any investment results. These limitations on withdrawals
apply to: (1) salary reduction contributions made after December 31, 1988; (2)
income attributable to such contributions; and (3) income attributable to
amounts held as of December 31, 1988. The limitations on withdrawals do not
affect rollovers or exchanges between certain Qualified Plans. Tax penalties may
also apply. (See "Taxes -- Tax Sheltered Annuities -- Withdrawal Limitations").
 
     While the foregoing limitations only apply to certain contracts issued in
connection with 403(b) Qualified Plans, all Contract Owners should seek
competent tax advice regarding any withdrawals or distributions.
 
     Except in connection with the Systematic Withdrawal Program, the minimum
partial withdrawal amount is $500, or the Owner's entire interest in the
Division from which a withdrawal is requested. The Owner's interest in the
Division from which the withdrawal is requested must be at least $500 after the
withdrawal is completed if anything is left in that Division.
 
     A written withdrawal request or Systematic Withdrawal Program enrollment
form, as the case may be, must be sent to the Company, c/o its Administrative
Service Center. The required form will not be in good order unless it includes
the Contract Owner's Tax I.D. Number (e.g., Social Security Number) and provides
instructions regarding withholding of income taxes. The Company provides the
required forms.
 
     If the request is for total withdrawal, the Contract or a Lost Contract
Affidavit (which may be obtained by calling the Company's Administrative Service
Center) must be submitted as well. The Withdrawal Value is determined on the
basis of the Accumulation Unit values next computed following receipt of a
request in proper order. The Withdrawal Value will be paid within seven days
after the day a proper request is received by the Company. However, the Company
may suspend the right of withdrawal or delay payment more than seven days: (1)
during any period when the New York Stock Exchange is closed (other than
customary weekend and holiday closings); (2) when trading on the markets the
Separate Account or Portfolios normally utilize is restricted or an emergency
exists as determined by the Securities and Exchange Commission so that disposal
of the Separate Account's or a Portfolio's investments or determination of
Accumulation Unit value is not reasonably practicable; or (3) for such other
periods as the Securities and Exchange Commission, by order, may permit for
protection of Contract Owners.
 
SYSTEMATIC WITHDRAWAL PROGRAM
 
     Certain Participants of Nonqualified Plan Contracts and Contracts issued in
connection with IRAs may choose to withdraw amounts which in the aggregate add
up to a maximum of 10% of their Purchase Payments annually pursuant to a
Systematic Withdrawal Program without charge. Withdrawals are taxable and a 10%
federal tax penalty may apply to withdrawals before age 59 1/2. Participants
must complete an enrollment form which describes the program and send it to the
Company, c/o its Administrative Service Center. Participation in the Systematic
Withdrawal Program may be elected at the time the Contract is issued or on any
date prior to the Annuity Date. Depending on fluctuations in the net asset value
of the Portfolios, systematic withdrawals may reduce or even exhaust Contract
Value. The minimum systematic withdrawal amount is $250 per withdrawal.
 
     Amounts withdrawn under to the Systematic Withdrawal Program may be
electronically wired to the Contract Owner's financial institution by completing
the instructions on the Electronic Fund Transfer Form or by written request
delivered to the Company at its Administrative Service Center. A voided check
(for checking accounts), the
                                       23
<PAGE>   28
 
account number and bank ABA number must accompany all requests. Electronic
transfers may also be requested on the Systematic Withdrawal Request Form. The
Company reserves the right to modify, suspend or terminate the Systematic
Withdrawal Program and the availability of electronic fund transfers at any
time.
 
ERISA PLANS
 
     Spousal consent may be required when a married Contract Owner seeks a
distribution from a Contract that has been issued in connection with a Qualified
Plan or a Non-Qualified Plan that is subject to Title I of ERISA. Owners should
obtain competent advice.
 
TEXAS OPTIONAL RETIREMENT PROGRAM
 
     A participant in the Texas Optional Retirement Program ("ORP") is required
to obtain a certificate of termination from the participant's employer before a
Contract can be redeemed. This requirement is imposed because the Attorney
General of Texas has ruled that participants in the ORP may redeem their
interest in a Contract issued pursuant to the ORP only upon termination of their
employment by Texas public institutions of higher education, or upon retirement,
death or total disability.
 
MINIMUM CONTRACT VALUE
 
     If the Contract Value is less than $500 and no Purchase Payments have been
made during the previous three full calendar years, the Company reserves the
right, after 60 days written notice to the Owner, to terminate the Contract and
distribute the Withdrawal Value to the Owner. This privilege will be exercised
only if the Contract Value has been reduced to less than $500 as a result of
withdrawals, and state law permits. In no instance shall such termination occur
if the value has fallen below $500 due to either decline in Accumulation Unit
value or the imposition of fees and charges.
- --------------------------------------------------------------------------------
 
                                 ADMINISTRATION
- --------------------------------------------------------------------------------
 
     The Company has primary responsibility for all administration of the
Contracts and the Separate Account. Its Administrative Service Center is located
at P. O. Box 54299, Los Angeles, California 90054-0299 and its telephone number
is (800) 445-7862.
 
     The administrative services provided include, but are not limited to:
issuance of the Contracts; maintenance of Contract Owner records; Contract Owner
services; calculation of unit values; and preparation of Contract Owner reports.
 
     Contract statements and transaction confirmations are mailed to Contract
Owners at least quarterly. Contract Owners should read their statements
carefully and verify their accuracy. Questions about periodic statements should
be communicated to the Company promptly. The Company will investigate all
complaints and make any necessary adjustments retroactively, provided that it
has received notice of a potential error within 30 days after the date the
Contract Owner receives the questioned statement. If the Company has not
received notice of a potential error within this time, any adjustment shall be
made as of the date that the Administrative Service Center receives notice of
the potential error.
 
   
     The Company relies significantly on computer systems and applications in
its daily operations. Many of these systems and applications are not presently
year 2000 compliant. The Company's business, financial condition and results of
operations could be materially and adversely affected by the failure of the
Company's systems and applications (and those operated by third parties
interfacing with the Company's systems and applications) to properly operate or
manage dates beyond the year 1999. The Company has a coordinated plan to repair
or replace these noncompliant systems and to obtain similar assurances from
third parties interfacing with the Company's systems and applications and
expects to significantly complete its plan by the end of calendar year 1998,
leaving 1999 for testing.

- --------------------------------------------------------------------------------
 
     NOTE: THE FOLLOWING DESCRIPTION IS BASED UPON THE COMPANY'S UNDERSTANDING
OF CURRENT FEDERAL INCOME TAX LAW APPLICABLE TO ANNUITIES IN GENERAL. THE
COMPANY CANNOT PREDICT THE PROBABILITY THAT ANY CHANGES IN SUCH LAWS WILL BE
MADE. PURCHASERS ARE CAUTIONED TO SEEK COMPETENT TAX ADVICE REGARDING THE
POSSIBILITY OF SUCH CHANGES. THE COMPANY DOES NOT GUARANTEE THE TAX STATUS OF
THE CONTRACTS. PURCHASERS BEAR THE COMPLETE RISK THAT THE CONTRACTS MAY NOT BE
TREATED AS "ANNUITY CONTRACTS" UNDER FEDERAL INCOME TAX LAWS.
 
GENERAL
 
   
     From time to time, Federal initiatives are proposed that could affect the
tax treatment of insurance products. Recent administration budget proposals
include the proposed taxation of exchanges involving variable annuity contracts
and reallocations within variable annuity contracts and certain other proposals
relating to annuities. Please consult your tax advisor for additional
information.
    
 
   
     Currently, a Contract Owner is not taxed on increases in the value of a
Contract until distribution occurs, either in the form of a lump sum payment or
as annuity payments under the annuity option elected. For a lump sum payment
received as a total surrender (total redemption), the recipient is taxed on the
portion of the payment that exceeds the cost basis of the Contract. For a
payment received as a withdrawal (partial redemption), federal tax liability is
determined on a last-in-first-out basis, meaning taxable income is withdrawn
before the cost basis of the Contract is withdrawn. For Non-Qualified Contracts,
the cost basis is generally the Purchase Payments, while for Qualified Contracts
there may be no cost basis. The taxable portion of the lump sum payment is taxed
at ordinary income tax rates. Tax penalties may also apply.
    
 
     For annuity payments, the taxable portion is determined by a formula which
establishes the ratio that the cost basis of the Contract bears to the total
value of annuity payments for the term of the annuity Contract. The taxable
portion is taxed at ordinary income tax rates. For certain types of Qualified
Plans there may be no cost basis in the Contract within the meaning of Section
72 of the Code. 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 Contract 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 Contract Owner may elect in such cases to
 
                                       25
<PAGE>   30
 
waive the withholding requirement. If not waived, withholding is imposed (1) for
periodic payments, at the rate that would be imposed if the payments were wages,
or (2) for other distributions, at the rate of 10%. If no withholding exemption
certificate is in effect for the payee, the rate under (1) above is computed by
treating the payee as a married individual claiming 3 withholding exemptions.
 
DIVERSIFICATION
 
     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
Contract Owner with respect to earnings allocable to the Contract prior to the
receipt of payments under the Contract. The Code contains a safe harbor
provision which provides that annuity contracts such as the Contracts meet the
diversification requirements if, as of the close of each 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."
 
     The Company intends that each Portfolio of the Trust underlying the
Contracts will be managed by the investment adviser for the Trust in such a
manner as to comply with these diversification requirements.
 
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 combination of 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.
 
TAX TREATMENT OF ASSIGNMENTS
 
     An assignment of a Contract may be a taxable event and may also be
prohibited by ERISA in some circumstances. Contract Owners should therefore
consult competent tax advisers should they wish to assign their Contracts.
 
TAX TREATMENT OF WITHDRAWALS -- NON-QUALIFIED CONTRACTS
 
     Section 72 of the Code governs treatment of distributions from annuity
contracts. It provides that if the Contract Value exceeds the aggregate Purchase
Payments made, any amount withdrawn not in form of an annuity payment will be
treated as coming first from the earnings and then, only after the income
portion is exhausted, as coming from the principal. Withdrawn earnings are
includible in a taxpayer's gross income. Section 72 further provides that a 10%
penalty will apply to the income portion of any premature distribution. The
penalty is not imposed on amounts received: (1) after the taxpayer reaches
59 1/2; (2) upon the death of the Contract Owner; (3) if the taxpayer is totally
disabled; (4) in a series of substantially equal periodic payments made for the
life of
 
                                       26
<PAGE>   31
 
the taxpayer or for the joint lives of the taxpayer and his Beneficiary; (5)
under an immediate annuity; or (6) which are allocable to purchase payments made
prior to August 14, 1982.
 
     The above information applies to Qualified Contracts issued pursuant to
Section 457 of the Code, but does not apply to other Qualified Contracts.
Separate tax withdrawal penalties and restrictions apply to Qualified Contracts.
(See "Tax Treatment of Withdrawals -- Qualified Contracts").
 
   
QUALIFIED PLANS
    
 
     The Contracts offered by this Prospectus are designed to be suitable for
use under various types of Qualified Plans. Taxation of participants in each
Qualified Plan varies with the type of plan and the 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 informational 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. (See "Tax
Treatment of Withdrawals -- Qualified Contracts").
 
    (A) H.R. 10 OR KEOGH 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 participants 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. (See "Tax Treatment of Withdrawals -- Qualified Contracts").
     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, educational and
     scientific organizations described in Section 501(c)(3) of the Code. These
     qualifying employers may make contributions to the Contracts for the
     benefit of their employees. Such contributions are not includible in the
     gross income of the employee until the employee receives distributions from
     the Contract. The amount of contributions to the tax-sheltered annuity is
     limited to certain maximums imposed by the Code. Furthermore, the Code sets
     forth additional restrictions governing such items as transferability,
     distributions, nondiscrimination and withdrawals. (See "Tax Treatment of
     Withdrawals -- Qualified Contracts"). Any employee should obtain competent
     tax advice as to the tax treatment and suitability of such an investment.
 
   
    (C) INDIVIDUAL RETIREMENT ANNUITIES ("IRAS")
    
 
   
          Section 408(b) of the Code permits eligible individuals to contribute
     to an individual retirement program known as an "Individual Retirement
     Annuity" ("IRA"). Under applicable limitations, certain amounts may be
     contributed to an IRA which will be deductible from the individual's gross
     income. These IRAs are subject to limitations on eligibility,
     contributions, transferability and distributions. (See "Tax Treatment of
     Withdrawals -- Qualified Contracts"). Under certain conditions,
     distributions from other IRAs and other Qualified Plans may be rolled over
     or transferred on a tax-deferred basis into an IRA. Sales of Contracts for
     use with IRAs are
    
 
                                       27
<PAGE>   32
 
     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 408A 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 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 resulting income tax may be spread over four years if the
     conversion occurs before January 1, 1999. If and when Contracts are made
     available for use with Roth IRAs, they may be subject to special
     requirements imposed by the Internal Revenue Service. Purchases of the
     Contracts for this purpose will be provided with such supplementary
     information as may be required by the Internal Revenue Service 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 participants 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. (See "Tax Treatment of
     Withdrawals -- Qualified Contracts".) 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.
 
TAX TREATMENT OF WITHDRAWALS -- QUALIFIED CONTRACTS
 
     Section 72(t) of the Code imposes a 10% penalty tax on the taxable portion
of any early distribution from qualified retirement plans, including contracts
issued and qualified under Code Sections 401 (H.R. 10 and Corporate Pension and
Profit Sharing Plans), 403(b) (Tax-Sheltered Annuities) and 408(b) (IRAs).
 
   
     The tax penalty will not apply to the following distributions: (1) if
distribution is made on or after the date on which the Contract Owner or
Annuitant (as applicable) reaches age 59 1/2; (2) distributions following the
death or disability of the Contract Owner or Annuitant (as applicable) (for this
purpose "disability" is defined in Section 72(m)(7) of the Code); (3)
distributions that are part of substantially equal periodic payments made not
less frequently than annually for the life (or life expectancy) of the Contract
Owner or Annuitant (as applicable) or the joint lives (or joint life
expectancies) of such Contract Owner or Annuitant (as applicable) and his or her
designated Beneficiary; (4) distributions to a Contract Owner or Annuitant (as
applicable) who has separated from service after he or she has attained age 55;
(5) distributions made to the Contract Owner or Annuitant (as applicable) to the
extent such distributions do not exceed the amount allowable as a deduction
under Code Section 213 to the Contract Owner or Annuitant (as applicable) for
amounts paid during the taxable year for medical care; (6) distributions made to
an alternate payee pursuant to a qualified domestic relations order; and (7)
distributions from an IRA made to the Owner or Annuitant (as applicable) to the
extent such distributions do not exceed the Qualified Higher Education expense
(as defined in Section 72(t)(7) of the Code) of the Owner or Annuitant (as
applicable) for the taxable year; and (8) distribution from an IRA made to the
Owner or Annuitant (as applicable) which are Qualified First Time Home Buyer
distributions (as defined in Section 72(t)(8) of the Code).
    
 
     The exceptions stated in items (4), (5) and (6) above do not apply in the
case of an IRA.
 
     The taxable portion of a withdrawal or distribution from Contracts issued
under certain types of plans may, under some circumstances, be "rolled over"
into another eligible plan so as to continue to defer income tax on the taxable
portion. Effective January 1, 1993, such treatment is available for any
"eligible rollover distribution" made by certain types of plans (as described
above under "Taxes -- Withholding Tax on Distributions") that is transferred
within 60 days of receipt into a plan qualified under section 401(a) or 403(a)
of the Code, a tax-
                                       28
<PAGE>   33
 
sheltered annuity, an IRA, or an individual retirement account described in
section 408(a) of the Code. Plans making such eligible rollover distributions
are also required, with some exceptions specified in the Code, to provide for a
direct "trustee to trustee" transfer of the distribution to the transferee plan
designated by the recipient.
 
TAX SHELTERED ANNUITIES -- WITHDRAWAL LIMITATIONS
 
     The Tax Reform Act of 1986, effective January 1, 1989, limits the
withdrawal of amounts attributed to contributions made pursuant to a salary
reduction agreement (as defined in Section 403(b)(11) of the Code) to
circumstances only: when the Contract Owner attains age 59 1/2, separates from
service, dies, becomes disabled (within the meaning of Section 72(m)(7) of the
Code), or in the case of hardship. Withdrawals for hardship are restricted to
the portion of the Contract Owner's Contract Value which represents
contributions by the Contract Owner and does not include any investment results.
These limitations on withdrawals apply only to salary reduction contributions
made after December 31, 1988, to income attributable to such contributions, and
to income attributable to amounts held as of December 31, 1988. The limitations
on withdrawals do not affect rollovers or exchanges between certain Qualified
Plans. Contract Owners should consult their own tax counsel or other tax adviser
regarding any distributions.
 
DEFERRED COMPENSATION PLANS -- SECTION 457
 
     Under Section 457 of the Code, governmental and certain other tax exempt
employers may establish deferred compensation plans for the benefit of their
employees 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 a
participant or a beneficiary.

- --------------------------------------------------------------------------------
 
     There are no legal proceedings to which the Separate Account is a party or

        Information regarding the Anchor National Life Insurance Company (the
"Company") and its ownership is contained in the Prospectus.


                             INDEPENDENT ACCOUNTANTS

   
        The consolidated financial statements of the Company as of September 30,
1997 and 1996 and for each of the three years in the period ended September 30,
1997 are presented in this Statement of Additional Information. The consolidated
financial statements of the Company should be considered only as bearing on the
ability of the Company to meet its obligation under the Contracts. The financial
statements of the Separate Account as of December 31, 1997 and for each of the
two years in the period ended December 31, 1997, also are included in this
Statement of Additional Information.
    

        Price Waterhouse LLP, 400 South Hope Street, Los Angeles, California
90071, serves as the independent accountants for the Separate Account and the
Company. The financial statements referred to above included in this Statement
of Additional Information have been so included in reliance on the reports of
Price Waterhouse LLP, independent accountants, given on the authority of said
firm as experts in auditing and accounting.


                                  DISTRIBUTORS

        The Contracts are sold by licensed insurance agents, where the Contracts
may be lawfully sold, who are registered representatives of broker-dealers which
are registered under the Securities Exchange Act of 1934 and are members of the
National Association of Securities Dealers, Inc.

        The offering is on a continuous basis.

        Effective January 28, 1994, the Contracts are offered through the
distributors for the Separate Account, SunAmerica Capital Services, Inc., 733
Third Avenue, 4th Floor, New York, New York 10017, which is an indirect wholly

Central Avenue, Phoenix, Arizona 85004, and Royal Alliance Associates, Inc.,
located at 733 Third Street, 4th Floor, New York, New York 10017, served as
co-distributors of the Contract. SunAmerica Securities, Inc. and Royal Alliance

<PAGE>   38
                                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, 1997 were 3.30% and
3.35%, 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-RMC)/(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

        RMC = an allocated portion of the $30 annual Records Maintenance Charge,
              prorated for 7 days

   
        The change in the value of an Accumulation Unit during the 7 day period
reflects the income received, minus any expenses incurred, during such 7 day
period. The Records Maintenance Charge 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 Charge 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 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.


                                       2


<PAGE>   39
        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 ANNUAL RETURN (IN PERCENT) FOR PERIOD ENDING ON 12/31/97:

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

               P(1+T)n = ERV

        where:


                                       3


<PAGE>   40
                  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 Records
Maintenance Charges 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.

                                ANNUITY 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 Annuity Payments

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

</TABLE>

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



Subsequent Monthly Payments

        The amount of the second and subsequent annuity 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 annuity payment is due.
The dollar amount of the first annuity 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 annuity payment. The number of Annuity Units
determined for the first annuity payment remains constant for the second and
subsequent monthly payments.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. NATURE OF OPERATIONS
 
     Anchor National Life Insurance Company (the "Company") is a wholly owned
indirect subsidiary of SunAmerica, Inc. (the "Parent"). The Company is an
Arizona-domiciled life insurance company and conducts its business through three
segments: annuity operations, asset management and broker-dealer operations.
Annuity operations include the sale and administration of fixed and variable
annuities and guaranteed investment contracts. Asset management, which includes
the sale and management of mutual funds, is conducted by SunAmerica Asset
Management Corp. Broker-dealer operations include the sale of securities and
financial services products, and are conducted by Royal Alliance Associates,
Inc.
 
     The operations of the Company are influenced by many factors, including
general economic conditions, monetary and fiscal policies of the federal
government, and policies of state and other regulatory authorities. The level of
sales of the Company's financial products is influenced by many factors,
including general market rates of interest; strength, weakness and volatility of
equity markets; and terms and conditions of competing financial products. The
Company is exposed to the typical risks normally associated with a portfolio of
fixed-income securities, namely interest rate, option, liquidity and credit
risk. The Company controls its exposure to these risks by, among other things,
closely monitoring and matching the duration of its assets and liabilities,
monitoring and limiting prepayment and extension risk in its portfolio,
maintaining a large percentage of its portfolio in highly liquid securities, and
engaging in a disciplined process of underwriting, reviewing and monitoring
credit risk. The Company also is exposed to market risk, as market volatility
may result in reduced fee income in the case of assets managed in mutual funds
and held in separate accounts.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     BASIS OF PRESENTATION: The accompanying consolidated financial statements
have been prepared in accordance with generally accepted accounting principles
and include the accounts of the Company and all of its wholly owned
subsidiaries. All significant intercompany accounts and transactions are
eliminated in consolidation. Certain prior period amounts have been reclassified
to conform with the 1997 presentation.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions
that affect the amounts reported in the financial statements and the
accompanying notes. Actual results could differ from those estimates.
 
     INVESTMENTS: Cash and short-term investments primarily include cash,
commercial paper, money market investments, repurchase agreements and short-term
bank participations. All such investments are carried at cost plus accrued
interest, which approximates fair value, have maturities of three months or less
and are considered cash equivalents for purposes of reporting cash flows.
 
     Bonds, notes and redeemable preferred stocks available for sale and common
stocks are carried at aggregate fair value and changes in unrealized gains or
losses, net of tax, are credited or charged directly to shareholder's equity.
Bonds, notes and redeemable preferred stocks are reduced to estimated net
realizable value when necessary for declines in value considered to be other
than temporary. Estimates of net realizable value are subjective and actual
realization will be dependent upon future events.
 
     Mortgage loans are carried at amortized unpaid balances, net of provisions
for estimated losses. Real estate is carried at the lower of cost or fair value.
Other invested assets include investments in limited partnerships, which are
accounted for by using the cost method of accounting; separate account
investments; leveraged leases; policy loans, which are carried at unpaid
balances; and collateralized mortgage obligation residuals.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
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 using the specific cost
identification method. Premiums and discounts on investments are amortized to
investment income using the interest method over the contractual lives of the
investments.
 
     INTEREST RATE SWAP AGREEMENTS: The net differential to be paid or received
on interest rate swap agreements ("Swap Agreements") entered into to reduce the
impact of changes in interest rates is recognized over the lives of the
agreements, and such differential is classified as Interest Expense in the
income statement. All outstanding Swap Agreements are designated as hedges and,
therefore, are not marked to market. However, in the event that a hedged
asset/liability were to be sold or repaid before the related Swap Agreement
matures, the Swap Agreement would be marked to market and any gain/loss
classified with any gain/loss realized on the disposition of the hedged
asset/liability. Subsequently, the Swap Agreement would be marked to market and
the resulting change in fair value would be included in Investment Income in the
income statement. In the event that a Swap Agreement that is designated as a
hedge were to be terminated before its contractual maturity, any resulting
gain/loss would be credited/charged to the carrying value of the asset/liability
that it hedged.
 
     DEFERRED ACQUISITION COSTS: Policy acquisition costs are deferred and
amortized, with interest, in relation to the incidence of estimated gross
profits to be realized over the estimated lives of the annuity contracts.
Estimated gross profits are composed of net interest income, net realized
investment gains and losses, variable annuity fees, surrender charges and direct
administrative expenses. Costs incurred to sell mutual funds are also deferred
and amortized over the estimated lives of the funds obtained. Deferred
acquisition costs consist of commissions and other costs that vary with, and are
primarily related to, the production or acquisition of new business.
 
     As debt and equity securities available for sale are carried at aggregate
fair value, an adjustment is made to deferred acquisition costs equal to the
change in amortization that would have been recorded if such securities had been
sold at their stated aggregate fair value and the proceeds reinvested at current
yields. The change in this adjustment, net of tax, is included with the change
in net unrealized gains or losses on debt and equity securities available for
sale that is credited or charged directly to shareholder's equity. Deferred
Acquisition Costs have been decreased by $16,400,000 at September 30, 1997 and
increased by $4,200,000 at September 30, 1996 for this adjustment.
 
     VARIABLE ANNUITY ASSETS AND LIABILITIES: The assets and liabilities
resulting from the receipt of variable annuity premiums are segregated in
separate accounts. The Company receives administrative fees for managing the
funds and other fees for assuming mortality and certain expense risks. Such fees
are included in Variable Annuity Fees in the income statement.
 
     GOODWILL: Goodwill, amounting to $18,311,000 at September 30, 1997, is
amortized by using the straight-line method over periods averaging 25 years and
is included in Other Assets in the balance sheet. Goodwill is evaluated for
impairment when events or changes in economic conditions indicate that the
carrying amount may not be recoverable.
 
     CONTRACTHOLDER RESERVES: Contractholder reserves for fixed annuity
contracts and guaranteed investment contracts are accounted for as
investment-type contracts in accordance with Statement of Financial Accounting
Standards No. 97, "Accounting and Reporting by Insurance Enterprises for Certain
Long-Duration Contracts and for Realized Gains and Losses from the Sale of
Investments," and are recorded at accumulated value (premiums received, plus
accrued interest, less withdrawals and assessed fees).
 
     FEE INCOME: Variable annuity fees, asset management fees and surrender
charges are recorded in income as earned. Net retained commissions are
recognized as income on a trade-date basis.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     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.

3. INVESTMENTS (CONTINUED)
     At September 30, 1997, bonds, notes and redeemable preferred stocks
included $216,877,000 (fair value of $227,169,000) of bonds and notes not rated
investment grade. The Company had no material concentrations of
noninvestment-grade assets at September 30, 1997.
 
     At September 30, 1997, the amortized cost of investments in default as to
the payment of principal or interest was $1,378,000, consisting of $500,000 of
non-investment-grade bonds and $878,000 of mortgage loans. Such nonperforming
investments had an estimated fair value of $1,378,000.
 
     As a component of its asset and liability management strategy, the Company
utilizes Swap Agreements to match assets more closely to liabilities. Swap
Agreements are agreements to exchange with a counterparty interest rate payments
of differing character (for example, variable-rate payments exchanged for
fixed-rate payments) based on an underlying principal balance (notional
principal) to hedge against interest rate changes. The Company typically
utilizes Swap Agreements to create a hedge that effectively converts
floating-rate assets and liabilities to fixed-rate instruments. At September 30,
1997, the Company had one outstanding Swap Agreement with a notional principal
amount of $15.9 million, which matures in December, 2024. The net interest paid
amounted to $0.1 million for the year ended September 30, 1997, and is included
in Interest Expense on Guaranteed Investment Contracts in the income statement.
 
     At September 30, 1997, $5,276,000 of bonds, at amortized cost, were on
deposit with regulatory authorities in accordance with statutory requirements.
 
4. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following estimated fair value disclosures are limited to reasonable
estimates of the fair value of only the Company's financial instruments. The
disclosures do not address the value of the Company's recognized and
unrecognized nonfinancial assets (including its real estate investments and
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.

4. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
     COMMON STOCKS: Fair value is based principally on independent pricing
services, broker quotes and other independent information.
 
     COST-METHOD PARTNERSHIPS: Fair value of limited partnerships accounted for
by using the cost method is based upon the fair value of the net assets of the
partnerships as determined by the general partners.
 
     VARIABLE ANNUITY ASSETS: Variable annuity assets are carried at the market
value of the underlying securities.
 
     RECEIVABLE FROM (PAYABLE TO) BROKERS FOR SALES (PURCHASES) OF
SECURITIES: Such obligations represent net transactions of a short-term nature
for which the carrying value is considered a reasonable estimate of fair value.
 
     RESERVES FOR FIXED ANNUITY CONTRACTS: Deferred annuity contracts and single
premium life contracts are assigned a fair value equal to current net surrender
value. Annuitized contracts are valued based on the present value of future cash
flows at current pricing rates.
 
     RESERVES FOR GUARANTEED INVESTMENT CONTRACTS: Fair value is based on the
present value of future cash flows at current pricing rates and is net of the
estimated fair value of hedging Swap Agreements, determined from independent
broker quotes.
 
     VARIABLE ANNUITY LIABILITIES: Fair values of contracts in the accumulation
phase are based on net surrender values. Fair values of contracts in the payout
phase are based on the present value of future cash flows at assumed investment
rates.
 
     SUBORDINATED NOTES PAYABLE TO PARENT: Fair value is estimated based on the
quoted market prices for similar issues.

6. CONTINGENT LIABILITIES
 
     The Company has entered into three agreements in which it has provided
liquidity support for certain short-term securities of three municipalities by
agreeing to purchase such securities in the event there is no other buyer in the
short-term marketplace. In return the Company receives a fee. The maximum
liability under these guarantees is $242,600,000. Management does not anticipate
any material future losses with respect to these liquidity support facilities.
 
     The Company is involved in various kinds of litigation common to its
businesses. These cases are in various stages of development and, based on
reports of counsel, management believes that provisions made for potential
losses relating to such litigation are adequate and any further liabilities and
costs will not have a material adverse impact upon the Company's financial
position or results of operations.
 
7. SHAREHOLDER'S EQUITY
 
     The Company is authorized to issue 4,000 shares of its $1,000 par value
Common Stock. At September 30, 1997 and 1996, 3,511 shares were outstanding.

insurance operations are accumulated in a memorandum policyholders' surplus
account and are taxed only when distributed to shareholders or when such account
exceeds prescribed limits. The accumulated policyholders' surplus was
$14,300,000 at September 30, 1997. The Company does not anticipate any
transactions which would cause any part of this surplus to be taxable.

                        REPORT OF INDEPENDENT ACCOUNTANTS


February 26, 1998


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, 1997, the results of their operations for the year
then ended, and the changes in their net assets for the two years then ended, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Separate Account's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities owned at
December 31, 1997 by correspondence with the custodian, provide a reasonable
basis for the opinion expressed above.

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. 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 twelve 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
        twelve Variable Accounts and do not include balances allocated to the
        General Account.

        The investment objectives and policies of the twelve 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.

                          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.

1.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

        The TARGET '98 PORTFOLIO seeks a predictable compounded investment
        return for the specified time period, consistent with preservation of
        capital. This portfolio invests primarily in zero coupon securities and
        current, interest-bearing, investment grade debt obligations which are
        issued by the U.S. Government, its agencies and instrumentalities, and
        both domestic and foreign corporations. These investments will generally
        mature no later than November 15, 1998. Accordingly, effective January
        1, 1998, no purchase payments or transfers into this portfolio are being
        accepted.

        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.

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:

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%.

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.

         Registrant undertakes to (1) file post-effective amendments to this
Registration Statement as frequently as is necessary to ensure that the audited
financial statements in the Registration Statement are never more than 16 months

accepted; (2) include either (A) as part of any application to purchase a
Contract offered by the prospectus forming a part of the Registration Statement,

aggregate (1) reasonable in relation to the risks assumed by the Company and (2)
reasonable in relation to the services rendered; and (3) reasonable in relation

         contract specifically to bring the redemption restrictions imposed by
         Section 403(b)(11) to the attention of the potential participants;

4.       Obtain from each plan participant who purchases a Section 403(b)
         annuity contract, prior to or at the time of such purchase, a signed
         statement acknowledging the participant's understanding of (1) the
         restrictions on redemption imposed by Section 403(b)(11), and (2) other
         investment alternatives available under the employer's Section 403(b)
         arrangement to which the participant may elect to transfer his contract
         value.

                                PURCHASE PAYMENTS

Purchase Payments are flexible. This means that you, subject to the minimums and
maximums given below, may change the amount and the frequency or timing of
Purchase Payments. The minimum initial Purchase Payment we will accept for a
Contract issued pursuant to a Non-Qualified Plan is $1,000. Subsequent Purchase
Payments must be at least $500.

The minimum initial Purchase Payment we will accept for a Contract issued
pursuant to a Qualified Plan is $100. Purchase Payments will be allocated to one
or more Separate Account Divisions. At least $500 must be allocated to each
Division selected before an allocation can be made to an additional Division. If
the Contract Value is less than $500, and no Purchase Payments have been made
during the previous three full calendar years, we reserve the right, after 60
days written notice to you, to terminate this Contract and distribute the
Withdrawal Value to you.

                           ACCUMULATION PERIOD

PURCHASE PAYMENTS AND CONTRACT VALUE - We will credit a Contract with the number
of Accumulation Units in a Division which results from dividing the Purchase
Payment(s) allocated to that Division, or the amount transferred into the
Division, by the Accumulation Unit Value for that Division at the end of the
Valuation Period next concluding after the allocation or transfer.

The Contract Value for any Valuation Period is determined by multiplying the
number of Accumulation Units credited to each Division by the Accumulation Unit
Value for that Division at the end of the Valuation Period and then adding the
resultant values.

ACCUMULATION UNIT VALUE - The Accumulation Unit Value of a Separate Account
Division for any Valuation Period is calculated by subtracting (2) from (1) and
dividing the result by (3) where:

(1)      is the total value of the assets of the Separate Account Division minus
         total liabilities;

(2)      is the cumulative unpaid charge for assumption of mortality and expense
         risks;

(3)      is the number of Accumulation Units outstanding at the end of such
         Valuation Period.

During the Accumulation Period, each Separate Account Division is assessed with
a daily charge for mortality and expense risks. The charge will equal an
aggregate of 1.25% per annum of the average daily net asset value of each
Division. Net asset value of each Division for any Valuation Period is
calculated by dividing (1) above by (3) above.

The Accumulation Unit Value may increase or decrease from Valuation Period to
Valuation Period.

RECORDS MAINTENANCE CHARGE - During the Accumulation Period, a Records
Maintenance Charge of $30 is assessed each Contract Year against each Contract
in force on the anniversary of the Issue Date. If a total surrender of Contract
Value is made, the charge will be assessed as of the date of surrender. If the
Contract participates in more than one Separate Account Division, an equal share
of the $30 charge will be made against each Division. The number of Accumulation
Units representing your Contract's interest in the affected Separate Account
Divisions will be reduced to reflect the Records Maintenance Charge.

ADMINISTRATIVE EXPENSE CHARGE - During the Accumulation period, each Separate
Account Division is assessed with a daily charge for mortality and expense
risks. The charge will equal an aggregate of .15% per annum of the average daily
net asset value of each Division. Net asset value of each Division for any
Valuation Period is calculated dividing (1) by (3) as described in the
Accumulation Unit Value provision. This charge will be reduced to the extent it
exceeds that required for administrative expenses.

TRANSFERS DURING ACCUMULATION PERIOD - You may transfer all or part of the
Contract Value among Separate Account Divisions subject to the following
conditions:

(1)      the minimum amount which may be transferred from a Division is $500 or,
         the remaining Contract Value in a Separate Account Division if less
         than $500;

(2)      no partial transfer can be made if your remaining Contract Value in a
         Separate Account Division will be less than $500 after the transfer;


<PAGE>   5
(3)      transfers will be honored on the Valuation Date next following receipt
         by us of a written direction (containing all required information);

(4)      if you make a transfer within 30 days of the Issue Date, a transfer fee
         of $25 ($10 in Pennsylvania and Texas) will be charged.

We reserve the right to at any time suspend, modify, or terminate the transfer
privilege at any time with notice.

The Accumulation Units credited to a Separate Account Division will be reduced
based on the Accumulation Unit Value at the end of the Valuation Period next
following the Valuation Period during which we receive a completely detailed
request for a transfer. Accumulation Units will be credited to the Contract
Value in the Separate Account Division to which the transfer is being made at
the same time.

TOTAL WITHDRAWAL DURING THE ACCUMULATION PERIOD - You may, during the
Accumulation Period, withdraw all the Contract Value remaining after deduction
of the Withdrawal Charge, if any.

An election for total withdrawal must be made in writing to us at our Annuity
Service Office. Payment made to us in honoring an election for total withdrawal
prior to receipt by us of notice of the death of the Annuitant or the Owner will
discharge our obligations under this Contract.

PARTIAL WITHDRAWALS DURING THE ACCUMULATION PERIOD - You may, during the
Accumulation Period, withdraw portions of the Contract Value, subject to the
following conditions:

(1)      each partial withdrawal must be for an amount which is not less than
         $500 or, if smaller, the remaining value in a Separate Account
         Division;

(2)      the remaining value in each Separate Account Division from which a
         partial withdrawal is requested must be at least $500 after the partial
         withdrawal is completed;

(3)      an election to make a partial withdrawal must be made in writing to us
         at our Annuity Service Office;

(4)      the election must indicate the amount(s) and the Separate Account
         Division(s) from which the partial withdrawal is requested;

(5)      the maximum amount of a partial withdrawal will be equal to the
         Contract Value in the Division minus the amount of the Withdrawal
         Charge, if any; and

(6)      you have the right to specify the Division from which a withdrawal is
         to be made.

Any payment made by us for partial withdrawal prior to receipt by us of notice
of the death of the Annuitant or the Owner will discharge our obligation under
this Contract to the extent of the payment.

IF A WITHDRAWAL CHARGE IS APPLICABLE. THE REDUCTION IN THE CONTRACT VALUE
REQUIRED TO PRODUCE THE AMOUNT F THE PARTIAL WITHDRAWAL REQUESTED WILL BE
GREATER THAN THE AMOUNT ACTUALLY PAID BY US TO YOU. THE ACTUAL DOLLAR AMOUNT OF
A PARTIAL WITHDRAWAL REQUESTED WILL BE THE AMOUNT PAID TO YOU.

FREE WITHDRAWAL AND WITHDRAWAL CHARGES -
(1)      all Purchase Payments in a given Contract Year are totalled and are
         used separately in calculating applicable Withdrawal Charges.

(2)      all withdrawals will be assessed first against Purchase Payments in the
         earliest Contract Years.

(3)      The amount which may be withdrawn in any Contract Year without a
         Withdrawal Charge is 10% of the aggregate Purchase Payments made as of
         the date of the partial withdrawal, less prior withdrawals. A free
         withdrawal can be made only once per Contract Year and must be the
         first withdrawal in that Contract Year. No free withdrawal is permitted
         during the first Contract Year.

(4)      any amount withdrawn which exceeds the limitations specified in (3)
         above will be subject to a Withdrawal Charge in accordance with the
         Withdrawal Charge Table.

         Sixth and later                             0%

The Rate applies to Purchase Payments.

WITHDRAWAL PROCEDURES - The Accumulation Units credited to a Contract in a
Separate Account Division will be reduced based on the Accumulation Unit Value
at the end of the Valuation Period during which an election of withdrawal
completely contained all required information is received by us at our Annuity
Service Office. An amount withdrawn will be paid within seven calendar days
after the date proper written election is received by us, except as provided
below.

SUSPENSION OF WITHDRAWAL PRIVILEGES - We may suspend the right of withdrawal
privileges or delay payment more than seven calendar days:

(1)      during any period when the New York Stock Exchange is closed (other
         than customary weekend and holiday closings);

(2)      when trading in the markets the Account or a Portfolio normally
         utilizes is restricted or an emergency exists as determined by the
         Securities and Exchange Commission so that disposal of the Account's or
         Portfolio's investments or determination of Accumulation Unit Value is
         not reasonably practicable; or

(3)      for such other periods as the Securities and Exchange Commission by
         order may permit for protection of the Contract Owners.

                                  DEATH BENEFIT

The Death Benefit is equal to the greater of:

(1)      the Contract Value at the end of the Valuation Period during which Due
         Proof of death and an election of the type of payment by the
         Beneficiary is received by us at our Annuity Service Office; or

(2)      the total dollar amount of Purchase Payments minus the total dollar
         amount of partial withdrawals and applicable withdrawal charges; and

(3)      after the firth Contract Year, the Contract Value at the last Contract
         Anniversary minus the total dollar amount of partial withdrawals made
         since that anniversary.

Payment of the Death Benefit may be made in one lump sum or applied under one of
the Annuity Options.

Due Proof of death means a certified copy of a death certificate or a certified
copy of a decree of a court of competent jurisdiction as to a finding of death,
or written statement by a Doctor of Medicine who attended the deceased at time
of death, or any other proof satisfactory to us.

DEATH OF ANNUITANT - The Death Benefit will be payable to the Beneficiary upon
receipt by us of Due Proof of the Annuitant's death during the Accumulation
Period.

                                 DEATH OF OWNER

The following section applies only if this Contract is issued on a non-qualified
basis and if either of the two following conditions exist:

(A)      The Owner and the Annuitant are the same individual and that individual
         dies during the Accumulation Period; or

(B)      The Owner and Annuitant are different persons and the Owner dies during
         the Accumulation Period prior to the Annuitant's death.

If either of the above conditions occur, the following provisions apply:

(1)      If the Beneficiary is the spouse of the Owner, then the Beneficiary
         becomes the Owner and this Contract remains in full force and effect.


<PAGE>   7
(2)      If the Beneficiary is a natural person and not the spouse of the Owner,
         the Beneficiary becomes the Owner. The Beneficiary becomes the Owner.
         The Beneficiary can elect to have the existing Contract Value paid
         under one of the Annuity Options set forth in this Contract over a
         period not extending beyond the life expectancy of the Beneficiary at
         the time of the election: however, payments under any Annuity Option
         selected must begin not later than one year after the date of death of
         the previous Owner.

         Alternatively, the Beneficiary may elect to receive a lump sum
         distribution of the greater of: (a) the current Contract Value at the
         time of election; or (b) the total amount of Purchase Payments made
         under the Contract less the aggregate dollar amount of any partial
         withdrawals. Under this alternative election, the lump sum must be paid
         to the Beneficiary within five years of the previous Owner's death.

(3)      If there is no Beneficiary or if the Beneficiary is not a natural
         person, then the entire Contract Value must be paid out within five
         years of the Owner's death.

                                 ANNUITY PERIOD

ELECTION OF ANNUITY OPTION AND ALLOCATION OF ANNUITY PAYMENTS - Election of an
Annuity Option must be made by written notice to us at our Annuity Service
Office. The election may be made:

(1)      by the Owner prior to the Annuity Date and Annuitant's death;

(2)      by the Annuitant on the Annuity Date unless the Owner has restricted
         the right to make an election; or

(3)      by the Beneficiary upon the Annuitant's death unless the Owner has
         restricted the right to make an election.

If the Contract Value to be applied is less than $5,000, we may make payment in
one lump sum. If the amount of the first scheduled payment is less than $50, we
may increase the interval between payments to a quarterly, semi-annual or annual
payment to make the first payment at least $50. Option 3 may be elected only if
the Contract Value to be applied is at least $20,000. Payment must be made to a
natural person referred to as the payee.

The amount we use in determining annuity payments under Options 1, 2, and 3,
subject to adjustment for any applicable Withdrawal Charge and premium taxes, is
the Contract Value at the end of the Valuation Period immediately preceding the
Valuation Period which includes the Annuity Date. If Option 1 or 2 is elected,
no Withdrawal Charge will apply.

Payment under Option 3 or in accordance with the Other Settlement Arrangements
section may subject the Contract Value to a Withdrawal Charge. If Option 3 is
elected, the Contract Value may be subject to a Withdrawal Charge in accordance
with the Withdrawal Charge Table.

If no other Annuity Option is elected, the amount payable will be made under
Option 1 with a 10 year period certain.

ANNUITY OPTIONS - The amount payable may be paid under one of the following
options or in any other manner agreed to by us:

OPTION 1 - LIFE ANNUITY WITH INSTALLMENTS GUARANTEED - We will make monthly
payments for the guaranteed period elected and then for the remaining lifetime
of the payee. The period elected may be only 10 or 20 years. If the payee dies
before the end of the guaranteed period, the present value, based on a 5% annual
interest rate, of remaining guaranteed payments will be paid to the payee's
estate or the Beneficiary.

OPTION 2 - JOINT AND SURVIVOR ANNUITY - We will pay the full monthly income
while both payees are living. Upon the death of either payee, income will
continue during the lifetime of the surviving payee at the percentage of such
full amount chosen when this option was elected.

OPTION 3 - INCOME FOR SPECIFIED PERIOD - We will make monthly payments for the
period elected but not less than 5 years or more than 30 years. The election
must be made for full twelve-month periods.

OTHER SETTLEMENT ARRANGEMENTS - Our agreement is necessary for other payment
methods.

VARIABLE ANNUITY - The Contract Value at the end of the Valuation Period
immediately preceding the Valuation Period which includes the Annuity Date will
first be reduced by the dollar amount of any Withdrawal Charge and then by any
applicable premium taxes. The remaining value will be used to calculate the


<PAGE>   8
first monthly annuity payment. For Annuity Options 1, 2 and 3, the first monthly
annuity payment will be based upon the Annuity Option elected and the
appropriate Annuity Option Table.

With respect to Options 1, 2 and 3, the number of Annuity Units for each
Separate Account Division for purposes of determining subsequent annuity
payments is determined by dividing the amount of the first monthly annuity
payment attributable to the Contract Value in that Separate Account Division by
the Annuity Unit Value for the Division at the end of the Valuation Period which
includes the Annuity Date. The number of Annuity Units per payment will remain
fixed unless a transfer is made. The amount of any subsequent annuity payments
will be determined by multiplying the number of Annuity Units per payment in
each Separate Account Division by the Annuity Unit Value for that Division at
the end of the Valuation Period immediately preceding the valuation Period which
includes the date on which payment is to be made and then adding the resultant
values. The Annuity Unit Value may increase or decrease from Valuation Period to
Valuation Period.

We guarantee that the dollar amount of each annuity payment after the first will
not be adversely affected by variations in actual expenses or by variations in
mortality experience from the expense and mortality assumptions on which the
first payment is based.

The Annuity Tables are based on the 1983 Table A, projected at Scale G with
interest at the rate of 5% per annum and assume births in year 1942. The amount
of each annuity payment will depend upon the sex and adjusted age of the
Annuitant, he joint annuitant, if any, or other payee. The adjusted age is
determined from the actual age nearest birthday at the time the first monthly
annuity payment is due according to the Table A below.

ANNUITY UNIT VALUE - For each Separate Account Division, the value of an Annuity
Unit at the end of 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 of .999866337 per
calendar day of such Valuation Period to offset the effect of the assumed rate
of 5.00% per annum in the Annuity Option Table.

The net investment factor for each Division for any Valuation Period is
determined by dividing:

(1)      the value of an Accumulation Unit of the applicable Division as of the
         end of the current Valuation Period: by

(2)      the value of an Accumulation Unit of the applicable Division as of the
         end of the immediately preceding Valuation Period.

TRANSFERS DURING THE ANNUITY PERIOD - During the Annuity Period, the payee(s)
may transfer the Contract Value in the Separate Account Divisions. To do so,
send a written request to our Annuity Service Office. A transfer may be made
subject to the following:

(1)      a transfer may be made once each Contract Year;

(2)      a request for a transfer must be received by us at our Annuity Service
         Office at least 45 days before the Contract Anniversary as of which the
         transfer will take effect;

(3)      a transfer will be effected at the next Annuity Unit Value calculated
         after we receive the transfer request;

(4)      no transfer may be made during the first year of the Annuity Period;

(5)      the entire interest in a Separate Account Division must be transferred.


<PAGE>   9
The number of Annuity Units per payment attributable to a Separate Account
Division to which a transfer(s) is made, determined as of the effective date of
the transfer, will be equal to the number of Annuity Units per payment in the
Division from which the transfer(s) is being made multiplied by the Annuity Unit
Value for that Division, the amount being divided by the Annuity Unit Value for
the Separate Account Division to which transfer is being made.

We reserve the right at any time and without prior notice to any party to
terminate, suspend or modify the transfer privileges described above.

SUPPLEMENTARY ANNUITY AGREEMENT - An Annuity Agreement will be issued to reflect
payments to be made under an Annuity Option. If settlement is a result of
Annuitant's death or the Owner's death, the effective date of the Annuity
Agreement will be the date of receipt of Due Proof of death, as defined above.
Otherwise, the effective date will be the date specified in the Annuity
Agreement.

CHANGE OF ANNUITY DATE - You may elect to change the Annuity Date during the
lifetime of the Annuitant. An election to change the Annuity Date must be in
written form received by us at our Annuity Service Office at least 7 days before
the Annuity Date then reflected on our records.

EVIDENCE OF AGE, SEX AND SURVIVAL - We may require satisfactory evidence of:

(1)      the age and sex of any person(s) on whose life the annuity payments are
         to be based; and

(2)      the continued survival of any person(s) on whose life the annuity
         payments are based.

DISBURSEMENT OF FUNDS UPON DEATH OF PAYEE - At the payee's death, unless
otherwise provided in the Annuity Agreement, the commuted value, based on 5.00%
interest of any remaining unpaid guaranteed installments, will be paid in one
sum to the Beneficiary. The value (to be commuted) of the remaining installments
will be determined by using (for all payments) the Annuity Unit Value next
determined after Due Proof of death is received by us.

PROTECTION OF BENEFITS - Unless otherwise provided in the Annuity Agreement, the
payee may not commute, anticipate, assign, alienate or otherwise encumber any
payment to be made.

CREDITORS - Proceeds under this Contract and any payment under any of the above
options will exempt from the claims of creditors and from legal process to the
extent permitted by law.

Ownership may be change at any time during the Annuitant's lifetime. A change
must be made by written notice from the Owner sent to us at our Annuity Service
Office with information sufficient to clearly identify the new Owner to us. No
change will take effect until received by us. Upon being received, any change
will take effect as of the date it was signed, except for action taken by us
before the change was received. We reserve the right to require this Contract
for endorsement of a change.

ASSIGNMENT - No assignment of this Contract is binding until received by us at
our Annuity Service Office. We assume no responsibility for the validity of any
assignment.

NOTE:  AN ASSIGNMENT MAY CONSTITUTE A TAXABLE EVENT.  YOU SHOULD FIRST CONSULT
WITH YOUR TAX ADVISOR.

Any claim under an assignment is subject to proof of the extent of interest. If
this Contract is assigned, your rights and the Beneficiary's rights are subject
to the rights of any assignee of record.

OWNERSHIP OF THE SEPARATE ACCOUNT ASSETS - We have exclusive ownership and
control of all assets in the Separate Account.

LIABILITIES OF SEPARATE ACCOUNTS - The assets held in the Separate Account will
not be charged with liabilities arising out of any other business we may
conduct. The assets are held and applied exclusively for the benefit of Owners,
Annuitants, Beneficiaries or payees of the Variable Annuity Contracts.

NONPARTICIPATION IN SURPLUS - This Contract does not share in our profits or
surplus.

DELAY OF PAYMENTS - We may defer making any payments for up to six months.

SUSPENSION OF PAYMENTS - We may suspend or postpone payments if any of the
following occur;

(1)      during any period when the New York Stock Exchange is closed (other
         than customary weekend and holiday closings);


<PAGE>   13
(2)      when trading in the markets the Account or a portfolio normally
         utilizes is restricted, or an emergency exists as determined by the
         Securities and Exchange Commission so that disposal of the Account's or
         a Portfolio's investment or determination of Accumulation Unit Value is
         not reasonably practicable; or

(3)      for such other periods as the Securities and Exchange Commission by
         order may permit for protection of the Contract Owners.

REPORTS - Once each Contract Year, we will furnish you with an Annual Report of
the Separate Account and a statement showing the Contract Value.

ADDITION, SUBSTITUTION AND CONVERSION - We reserve the right to add additional
Eligible Portfolios from time to time. If additional Eligible Portfolios are
added, we will notify you in writing. If shares of a Portfolio are not available
for purchase or if, in our judgment, further investment in the shares is no
longer appropriate in view of the purposes of the Separate Account, shares of or
interests in another investment portfolio or company may be substituted for
Portfolio shares held or to be purchased by future Purchase Payments or
transfers under this Contract.

Further, if we deem it to be in the best interests of the Owners, the Separate
Account may be operated as a management company under the Investment Company Act
of 1940 or it may be deregistered under the Act in the event such registration
is no longer required or advisable. In the event any such substitution or change
occurs, we will promptly notify the Owners.

CHANGES IN THE LAW - If laws governing this Contract or the taxation of benefits
under this Contract change, we will amend this Contract to comply with these
changes.
