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

TRANSFERS                                   Before the Payout Start Date you may transfer your Contract
                                            value ("CONTRACT VALUE") among the investment alternatives,
                                            with certain restrictions. No minimum applies to the amount
                                            you transfer.

                                            We do not currently impose a fee upon transfers. However, we
                                            reserve the right to charge $10 per transfer after the 12th
                                            transfer in each "Contract Year," which we measure from the
                                            date we issue your Contract or a Contract anniversary
                                            ("CONTRACT ANNIVERSARY").

                                            anytime during the Accumulation Phase. Full or partial
                                            withdrawals are available under limited circumstances on or
                                            after the Payout Start Date.

                                            federal tax penalty may apply if you withdraw before you are
                                            59 1/2 years old. A withdrawal charge and MARKET VALUE

HOW THE CONTRACT WORKS
- -------------------------------------------------------------------

The Contract basically works in two ways.

First, the Contract can help you (we assume you are the CONTRACT OWNER) save for
retirement because you can invest in up to 35 investment alternatives and pay no
federal income taxes on any earnings until you withdraw them. You do this during
what we call the "ACCUMULATION PHASE" of the Contract. The Accumulation Phase
begins on the date we issue your Contract (we call that date the "ISSUE DATE")
and continues until the Payout Start Date, which is the date we apply your money
to provide income payments. During the Accumulation Phase, you may allocate your
purchase payments to any combination of the Variable Sub-Accounts and/or Fixed
Account Options. If you invest in any of the 3 Fixed Account Options, you will
earn a fixed rate of interest that we declare periodically. If you invest in any
of the Variable Sub-Accounts, your investment return will vary up or down
depending on the performance of the corresponding Portfolios.

Second, the Contract can help you plan for retirement because you can use it to
receive retirement income for life and/or for a pre-set number of years, by
selecting one of the income payment options (we call these "INCOME PLANS")
described on page 25. You receive income payments during what we call the
"PAYOUT PHASE" of the Contract, which begins on the Payout Start Date and
continues until we make the last payment required by the Income Plan you select.
During the Payout Phase, if you select a fixed income payment option, we
guarantee the amount of your payments, which will remain fixed. If you select a
variable income payment option, based on one or more of the Variable
Sub-Accounts, the amount of your payments will vary up or down depending on the
performance of the corresponding Portfolios. The amount of money you accumulate
under your Contract during the Accumulation Phase and apply to an Income Plan
will determine the amount of your income payments during the Payout Phase.

The timeline below illustrates how you might use your Contract.

As the Contract owner, you exercise all of the rights and privileges provided by
the Contract. If you die, any surviving Contract owner or, if there is none, the
BENEFICIARY will exercise the rights and privileges provided by the Contract.
SEE "The Contract." In addition, if you die before the Payout Start Date, we
will pay a death benefit to any surviving Contract owner or, if there is none,
to your Beneficiary. SEE "Death Benefits."

</TABLE>

The Portfolios' Advisors may discontinue all or part of these voluntary
reductions and reimbursements at any time.

(3) Initial Class. "Total Annual Portfolio Expenses" reflect offset and other
    arrangements that reduce expenses.

(4) A portion of the brokerage commissions that certain funds pay was used to
    reduce fund expenses. In addition, through arrangements with certain funds,
    or Fidelity Management & Research Company ("FMR") on behalf of certain
    funds, custodian, credits realized as a result of uninvested cash balances
    were used to reduce a portion of each applicable fund's expenses. With these
    reductions, the "Total Portfolio Annual Expenses" presented in the table
    would have been 0.65% for Contrafund-Registered Trademark- Portfolio, 0.56%
    for Equity-Income Portfolio, 0.65% for Growth Portfolio, and 0.87% for
    Overseas Portfolio.

(5) FMR agreed to reimburse a portion of the Index 500 Portfolio's expenses
    during the period. With this reimbursement, the Portfolio's "Management
    Fee," "Rule 12b-1 Fee," "Other Expenses," and "Total Portfolio Annual
    Expense" would have been: 0.24%, N/A, 0.04% and 0.28% respectively.

(6) Each series has an expense offset arrangement which reduces the series'
    custodian fee based upon the amount of cash maintained by the series with
    its custodian and dividend disbursing agent. Each series may enter into
    other such arrangements and directed brokerage arrangements, which would
    also have the effect of reducing the series' expenses. "Other Expenses" do
    not take into account these expense reductions, and are therefore higher
    than the actual expenses of the series. Had these fee reductions been taken
    into account, "Total Portfolio Annual Expenses" would be lower for certain
    series and would equal: 0.83% for Emerging Growth Series, 0.87% for Growth
    with Income Series, and 0.85% for Research Series.

(7) "Other Expenses" are based on estimated amounts for the current year.

(8) On February 8, 2000, a merger and reorganization was approved that combined
    the fund with a similar fund of Templeton Variable Products Series Fund,
    effective May 1, 2000. The table shows total expenses based on the fund's
    assets as of December 31, 1999, and not the assets of the combined fund.
    However, if the table reflected combined assets, the fund's expenses after
    May 1, 2000 would be estimated as: "Management Fees" 0.60%, "Rule 12b-1
    Fees" 0.25%, "Other Expenses" 0.04%, and "Total Portfolio Annual Expenses"
    0.89%.

(9) On February 8, 2000, a merger and reorganization was approved that combined
    the fund with a similar fund of Templeton Variable Products Series Fund,
    effective May 1, 2000. The table shows total expenses based on the fund's
    assets as of December 31, 1999, and not the assets of the combined fund.
    However, if the table reflected combined assets, the fund's expenses after
    May 1, 2000 would be estimated as: "Management Fees" 0.80%, "Rule 12b-1
    Fees" 0.25%, "Other Expenses" 0.05%, and "Total Portfolio Annual Expenses"
    1.10%.

(10) The fund administration fee is paid indirectly through the management fee.

(11) The funds' class 2 distribution plan or "Rule 12b-1 plan" is described in
    the fund's prospectus.

Please remember that you are looking at examples and not a representation of
past or future expenses. Your actual expenses may be lower or greater than those
shown above. Similarly, your rate of return maybe lower or greater than 5%,
which is not guaranteed. The above examples assume the election of the Enhanced
Death Benefit Rider with a mortality and expense risk charge of 1.35% rather
than 1.25%. If that Rider were not elected, the expense figures shown above
would be slightly lower. To reflect the contract maintenance charge in the
examples, we estimated an equivalent percentage charge, based on the current
average Contract size of $57,476.

FINANCIAL INFORMATION
- -------------------------------------------------------------------

To measure the value of your investment in the Variable Sub-Accounts during the
Accumulation Phase, we use a unit of measure we call the "ACCUMULATION UNIT."
Each Variable Sub-Account has a separate value for its Accumulation Units we
call "ACCUMULATION UNIT VALUE." Accumulation Unit Value is analogous to, but not
the same as, the share price of a mutual fund.

Attached as Appendix A to this prospectus are tables showing the Accumulation
Unit Values of each Variable Sub-Account since its inception. No Accumulation
Unit Values are shown for the following Variable Sub-Accounts which commenced
operations as of May 1, 2000: AIM V.I. Balanced, AIM V.I. Growth, AIM V.I.
Growth and Income, AIM V.I. Value, Fidelity VIP Contrafund-Registered
Trademark-, Fidelity VIP Equity-Income, Fidelity VIP Growth, Fidelity VIP High
Income, Fidelity VIP Index 500, Fidelity VIP Overseas, MFS Emerging Growth, MFS
Growth With Income, MFS Research, Oppenheimer Aggressive Growth, Oppenheimer
Capital Appreciation, Oppenheimer Global Securities, Oppenheimer Main Street
Growth & Income, STI Growth and Income, STI Quality Growth Stock, Templeton
Global Income Securities (Class 2), Templeton Growth Securities (Class 2). To
obtain a fuller picture of each Variable Sub-Account's finances, please refer to
the Variable Account's financial statements contained in the Statement of
Additional Information. The financial statements of Glenbrook also appear in the
Statement of Additional Information.

THE CONTRACT
- -------------------------------------------------------------------

CONTRACT OWNER
The STI Classic Variable Annuity is a contract between you, the Contract owner,
and Glenbrook, a life insurance company. As the Contract owner, you may exercise
all of the rights and privileges provided to you by the Contract. That means it
is up to you to select or change (to the extent permitted):

- - the investment alternatives during the Accumulation and Payout Phases,

- - the amount and timing of your purchase payments and withdrawals,

- - the programs you want to use to invest or withdraw money,

- - the income payment plan you want to use to receive retirement income,

- - the Annuitant (either yourself or someone else) on whose life the income
  payments will be based,

- - the Beneficiary or Beneficiaries who will receive the benefits that the
  Contract provides when the last surviving Contract owner dies, and

- - any other rights that the Contract provides.

If you die, any surviving Contract owner or, if none, the Beneficiary may
exercise the rights and privileges provided to them by the Contract.

The Contract cannot be jointly owned by both a non-natural person and a natural
person.

You can use the Contract with or without a qualified plan. A qualified plan is a
retirement savings plan, such as an IRA or tax-sheltered annuity, that meets the
requirements of the Internal Revenue Code. Qualified plans may limit or modify
your rights and privileges under the Contract. We use the term "Qualified
Contract" to refer to a Contract issued within a qualified plan. See "Qualified
Plans" on page 33.

ANNUITANT
The Annuitant is the individual whose age determines the latest Payout Start
Date and whose life determines the amount and duration of income payments (other
than under Income Plans with guaranteed payments for a specified period). You
initially designate an Annuitant in your application. The Annuitant must be a
natural person. If the Contract owner is a natural person, you may change the
Annuitant at any time prior to the Payout Start Date. You may designate a joint
Annuitant, prior to the Payout Start Date, who is a second person on whose life
income payments depend.

If the Annuitant dies prior to the Payout Start Date, the new Annuitant will be:

    (i) the youngest Contract owner; otherwise,

    (ii) the youngest Beneficiary.

BENEFICIARY
The Beneficiary is the person who may elect to receive the death benefit or
become the new Contract owner if the sole surviving Contract owner dies before
the Payout Start Date. If the sole surviving Contract owner dies after the
Payout Start Date, the Beneficiary will receive any guaranteed income payments
scheduled to continue.

You may name one or more Beneficiaries when you apply for a Contract. You may
change or add Beneficiaries at any time, unless you have designated an
irrevocable Beneficiary. We will provide a change of Beneficiary form to be
signed and filed with us. Any change will be effective at the time you sign the
written notice. Until we receive your written notice to change a Beneficiary, we
are entitled to rely on the most recent Beneficiary information in our files. We
will not be liable as to any payment or settlement made prior to receiving the
written notice. Accordingly, if you wish to change your Beneficiary, you should
deliver your written notice to us promptly.

If you did not name a Beneficiary or if the named Beneficiary is no longer
living, the Beneficiary will be:

- - your spouse or, if he or she is no longer alive,

- - your surviving children equally, or if you have no surviving children,

- - your estate.

If more than one Beneficiary survives you (the Annuitant if the Contract owner
is not a natural person), we will divide the death benefit among your
Beneficiaries according to your most recent written instructions. If you have
not given us written instructions, we will pay the death benefit in equal
amounts to the surviving Beneficiaries.

MODIFICATION OF THE CONTRACT
Only a Glenbrook officer may approve a change in or waive any provision of the
Contract. Any change or waiver must be in writing. None of our agents has the
authority to change or waive the provisions of the Contract. We may not change
the terms of the Contract without your consent, except to conform the Contract
to applicable law or changes in the law. If a provision of the Contract is
inconsistent with state law, we will follow state law.

                           13     - PROSPECTUS
<PAGE>
ASSIGNMENT
We will not honor an assignment of an interest in a Contract as collateral or
security for a loan. However, you may assign periodic income payments under the
Contract prior to the Payout Start Date. No Beneficiary may assign benefits
under the Contract until they are payable to the Beneficiary. We will not be
bound by any assignment until the Assignor signs it and files it with us. We are
not responsible for the validity of any assignment. Federal law prohibits or
restricts the assignment of benefits under many types of retirement plans and
the terms of such plans may themselves contain restrictions on assignments. An
assignment may also result in taxes or tax penalties. YOU SHOULD CONSULT WITH AN
ATTORNEY BEFORE TRYING TO ASSIGN YOUR CONTRACT.

PURCHASES
- -------------------------------------------------------------------

MINIMUM PURCHASE PAYMENTS
Your initial purchase payment must be at least $3,000 ($2,000 for a Qualified
Contract). All subsequent purchase payments must be $50 or more. You may make
purchase payments at any time prior to the earlier of the Payout Start Date or
your 86th birthday. We reserve the right to limit the maximum amount of purchase
payments we will accept.

AUTOMATIC ADDITIONS PROGRAM
You may make subsequent purchase payments by automatically transferring money
from your bank account. Please call or write us for an enrollment form.

ALLOCATION OF PURCHASE PAYMENTS
At the time you apply for a Contract, you must decide how to credit your
purchase payments among the investment alternatives. The allocation you specify
on your application will be effective immediately. All allocations must be in
whole percentages that total 100% or in whole dollars. You can change your
allocations by notifying us in writing. We reserve the right to limit
availability of the investment alternatives.

We will allocate your purchase payments to the investment alternatives according
to your most recent instructions on file with us. Unless you notify us in
writing otherwise, we will allocate subsequent purchase payments according to
the allocation for the previous purchase payment. We will effect any change in
allocation instructions at the time we receive written notice of the change in
good order.

We will credit the initial purchase payment that accompanies your completed
application to your Contract within 2 business days after we receive the payment
at our home office. If your application is incomplete, we will ask you to
complete your application within 5 business days. If you do so, we will credit
your initial purchase payment to your Contract within that 5 business day
period. If you do not, we will return your purchase payment at the end of the 5
business day period unless you expressly allow us to hold it until you complete
the application. We will credit subsequent purchase payments to the Contract at
the close of the business day on which we receive the purchase payment at our
home office.

We use the term "business day" to refer to each day Monday through Friday that
the New York Stock Exchange is open for business. We also refer to these days as
"VALUATION DATES." Our business day closes when the New York Stock Exchange
closes, usually 4 p.m. Eastern Time (3 p.m. Central Time). If we receive your
purchase payment after 3 p.m. Central Time on any Valuation Date, we will credit
your purchase payment using the Accumulation Unit Values computed on the next
Valuation Date.

RIGHT TO CANCEL
You may cancel the Contract by returning it to us within the Cancellation
Period, which is the 20 day period after you receive the Contract, or a longer
period should your state require it. You may return your Contract by delivering
it or mailing it to us. If you exercise this "RIGHT TO CANCEL," the Contract
terminates and we will pay you the full amount of your purchase payments
allocated to the Fixed Account. We also will return your purchase payments
allocated to the Variable Account adjusted, to the extent applicable law
permits, to reflect investment gain or loss that occurred from the date of
allocation through the date of cancellation. Some states may require us to
return a greater amount to you.

<PAGE>
CONTRACT VALUE
- -------------------------------------------------------------------

Your Contract Value at any time during the Accumulation Phase is equal to the
sum of the value of your Accumulation Units in the Variable Sub-Accounts you
have selected, plus the value of your interest in the Fixed Account Options.

ACCUMULATION UNITS
To determine the number of Accumulation Units of each Variable Sub-Account to
credit to your Contract, we divide (i) the amount of the purchase payment or
transfer you have allocated to a Variable Sub-Account by (ii) the Accumulation
Unit Value of that Variable Sub-Account next computed after we receive your
payment or transfer. For example, if we receive a $10,000 purchase payment
allocated to a Variable Sub-Account when the Accumulation Unit Value for the
Sub-Account is $10, we would credit 1,000 Accumulation Units of that Variable
Sub-Account to your Contract.

ACCUMULATION UNIT VALUE
As a general matter, the Accumulation Unit Value for each Variable Sub-Account
will rise or fall to reflect:

- - changes in the share price of the Portfolio in which the Variable Sub-Account
  invests, and

- - the deduction of amounts reflecting the mortality and expense risk charge,
  administrative expense charge, and any provision for taxes that have accrued
  since we last calculated the Accumulation Unit Value.

We determine contract maintenance charges, withdrawal charges, and transfer fees
(currently waived) separately for each Contract. They do not affect the
Accumulation Unit Value. Instead, we obtain payment of those charges and fees by
redeeming Accumulation Units. For details on how we compute Accumulation Unit
Value, please refer to the Statement of Additional Information.

We determine a separate Accumulation Unit Value for each Variable Sub-Account on
each Valuation Date. We also determine a separate set of Accumulation Unit
Values reflecting the cost of the Enhanced Death Benefit Rider described on

INVESTMENT ALTERNATIVES: THE FIXED ACCOUNT OPTIONS
- -------------------------------------------------------------------

You may allocate all or a portion of your purchase payments to the Fixed
Account. You may choose from among 3 Fixed Account Options, including a STANDARD
FIXED ACCOUNT OPTION, a DOLLAR COST AVERAGING FIXED ACCOUNT OPTION, and the
option to invest in one or more GUARANTEE PERIODS (included in the Guaranteed
Maturity Amount Fixed Account). The Fixed Account Options may not be available
in all states. Please consult with your representative for current information.
The Fixed Account supports our insurance and annuity obligations. The Fixed
Account consists of our general assets other than those in segregated asset
accounts. We have sole discretion to invest the assets of the Fixed Account,
subject to applicable law. Any money you allocate to a Fixed Account Option does
not entitle you to share in the investment experience of the Fixed Account.

STANDARD FIXED ACCOUNT OPTION AND
DOLLAR COST AVERAGING FIXED ACCOUNT OPTION

STANDARD FIXED ACCOUNT OPTION. Purchase payments and transfers that you allocate
to the Standard Fixed Account Option will earn interest for a one year period at
the current rate in effect at the time of allocation. We will credit interest
daily at a rate that will compound over the year to the effective annual
interest rate we guaranteed at the time of allocation. After the one year
period, we will declare a renewal rate which we guarantee for a full year.
Subsequent renewal dates will be every 12 months for each payment or transfer.
Each payment or transfer you allocate to this Option must be at least $50.

DOLLAR COST AVERAGING FIXED ACCOUNT OPTION. You may establish a Dollar Cost
Averaging Program by allocating purchase payments to the Dollar Cost Averaging
Fixed Account Option ("DCA Fixed Account Option"). We will credit interest to
purchase payments you allocate to this Option for up to one year at the current
rate in effect at the time of allocation. Each purchase payment you allocate to
the DCA Fixed Account Option must be at least $5,000. We reserve the right to
reduce the minimum allocation amount.

We will follow your instructions in transferring amounts monthly from the DCA
Fixed Account Option to one or more Variable Sub-Accounts. However, you may not
choose monthly installments of less than 3 or more than 12. Further, you must
transfer each purchase payment and all its earnings out of this Option to one or
more Variable Sub-Accounts by means of dollar cost averaging within the selected
program period. If you discontinue the Dollar Cost Averaging Program before the
end of the transfer period, we will transfer the remaining balance in this
Option to the Standard Fixed Account Option.

We bear the investment risk for all amounts allocated to the Standard Fixed
Account Option and the DCA Fixed Account Option. That is because we guarantee
the current and renewal interest rates we credit to the amounts you allocate to
either of these Options, which will never be less than the minimum guaranteed
rate in the Contract. Currently, we determine, in our sole discretion, the
amount of interest credited in excess of the guaranteed rate.

We may declare more than one interest rate for different monies based upon the
date of allocation to the Standard Fixed Account Option and the DCA Fixed
Account Option. For current interest rate information, please contact your
representative or Glenbrook at 1-800-755-5275.

GUARANTEE PERIODS
Each payment or transfer allocated to a Guarantee Period earns interest at a
specified rate that we guarantee for a period of years. Guarantee Periods may
range from 1 to 10 years. We are currently offering Guarantee Periods of 3, 5, 7
and 10 years in length. In the future we may offer Guarantee Periods of
different lengths or stop offering some Guarantee Periods.

Each payment or transfer allocated to a Guarantee Period must be at least $50.
We reserve the right to limit the number of additional purchase payments that
you may allocate to this Option.

INTEREST RATES. We will tell you what interest rates and Guarantee Periods we
are offering at a particular time. We will not change the interest rate that we
credit to a particular allocation until the end of the relevant Guarantee
Period. We may declare different interest rates for Guarantee Periods of the
same length that begin at different times.

We have no specific formula for determining the rate of interest that we will
declare initially or in the future. We will set interest rates based on
investment returns available at the time of the determination. In addition, we
may consider various other factors in determining interest rates including
regulatory and tax requirements, our sales commission and administrative
expenses, general economic trends, and competitive factors. WE DETERMINE THE
INTEREST RATES TO BE DECLARED IN OUR SOLE DISCRETION. WE CAN NEITHER PREDICT NOR
GUARANTEE WHAT THOSE RATES WILL BE IN THE FUTURE. For current interest rate
information, please contact your representative or Glenbrook at 1-800-755-5275.
The annual interest rate will never be less than the minimum guaranteed rate
stated in the Contract.

HOW WE CREDIT INTEREST. We will credit interest daily to each amount allocated
to a Guarantee Period at a rate that compounds to the annual interest rate that
we declared at the beginning of the applicable Guarantee Period.

</TABLE>

TOTAL INTEREST CREDITED DURING GUARANTEE PERIOD = $2,461.82
($12,461.82-$10,000.00)

This example assumes no withdrawals during the entire 5 year Guarantee Period.
If you were to make a withdrawal, you might be required to pay a withdrawal
charge. In addition, the amount withdrawn might be increased or decreased by a
Market Value Adjustment that reflects changes in interest rates since the time
you invested the amount withdrawn. The hypothetical interest rate is for
illustrative purposes only and is not intended to predict future interest rates
to be declared under the Contract. Actual interest rates declared for any given
Guarantee Period may be more or less than shown above but will never be less
than the guaranteed minimum rate stated in the Contract.

RENEWALS. At the end of each Guarantee Period, we will mail you a notice asking
you what to do with the relevant amount, including the accrued interest. During
the 30-day period after the end of the Guarantee Period, you may:

    1)  take no action. We will automatically apply your money to a new
        Guarantee Period of the same length as the expiring Guarantee Period.
        The new Guarantee Period will begin on the day the previous Guarantee
        Period ends. The new interest rate will be our then current declared
        rate for a Guarantee Period of that length; or

    2)  instruct us to apply your money to one or more new Guarantee Periods of
        your choice. The new Guarantee Period(s) will begin on the day the
        previous Guarantee Period ends. The new interest rate will be our then
        current declared rate for those Guarantee Periods; or

    3)  instruct us to transfer your money to the Standard Fixed Account Option.
        Your allocation will be effective on the day the previous Guarantee
        Period ends; or

    4)  instruct us to transfer all or a portion of your money to one or more
        Variable Sub-Accounts of the Variable Account. We will effect the
        transfer on the day we receive your instructions. We will not adjust the
        amount transferred to include a Market Value Adjustment; or

    5)  withdraw all or a portion of your money. You may be required to pay a
        withdrawal charge, but we will not adjust the amount withdrawn to
        include a Market Value Adjustment. The amount withdrawn will be deemed
        to have been withdrawn on the day the Guarantee Period ends. Amounts not
        withdrawn will be applied to a new Guarantee Period of the same length
        as the previous Guarantee Period. The new Guarantee Period will begin on
        the day the previous Guarantee Period ends.

                           19     - PROSPECTUS
<PAGE>
MARKET VALUE ADJUSTMENT. All withdrawals and transfers from a Guarantee Period,
other than those taken during the 30 day period after such Guarantee Period
expires, are subject to a Market Value Adjustment. A Market Value Adjustment
also applies upon payment of a death benefit under Contracts issued before
May 1, 1997 and when you apply amounts currently invested in a Guarantee Period
to an Income Plan (unless paid or applied during the 30 day period after such
Guarantee Period expires).

We apply the Market Value Adjustment to reflect changes in interest rates from
the time the amount being withdrawn or transferred was allocated to a Guarantee
Period to the time of its withdrawal, transfer, or application to an Income
Plan. As such, you bear some investment risk on amounts you allocate to any
Guarantee Period.

The Market Value Adjustment may be positive or negative, depending on changes in
interest rates. If interest rates increase significantly from the time you make
a purchase payment, the Market Value Adjustment, withdrawal charge, premium
taxes, and income tax withholding (if applicable) could reduce the amount you
receive upon full withdrawal of your Contract Value to an amount that is less
than the purchase payment plus interest at the minimum guaranteed interest rate
under the Contract.

Generally, if the effective annual interest rate for the Guarantee Period is
lower than the applicable current effective annual interest rate for a period
equal to the time remaining in the Guarantee Period, then the Market Value
Adjustment will result in a lower amount payable to you or transferred.
Similarly, if the effective annual interest rate for the Guarantee Period is
higher than the applicable current effective annual interest rate, then the
Market Value Adjustment will result in a higher amount payable to you or
transferred.

For example, assume that you purchase a Contract and select an initial Guarantee
Period of 5 years that has an effective annual rate of 4.50%. Assume that at the
end of 3 years, you make a partial withdrawal. If, at that later time, the
current interest rate for a 2 year Guarantee Period is 4.00%, then the Market
Value Adjustment will be positive, which will result in an increase in the
amount payable to you. Conversely, if the current interest rate for the 2 year
Guarantee Period is 5.00%, then the Market Value Adjustment will be negative,
which will result in a decrease in the amount payable to you.

The formula for calculating Market Value Adjustments is set forth in Appendix B
to this prospectus, which also contains additional examples of the application
of the Market Value Adjustment.

INVESTMENT ALTERNATIVES: TRANSFERS
- -------------------------------------------------------------------

TRANSFERS DURING THE ACCUMULATION PHASE
During the Accumulation Phase, you may transfer Contract Value among the
investment alternatives. You may request transfers in writing or by telephone
according to the procedure described below. There is no minimum transfer amount.
We currently do not assess, but reserve the right to assess, a $10 charge on
each transfer in excess of 12 per Contract Year. All transfers to or from more
than one Portfolio on a given day count as one transfer.

We will process transfer requests that we receive before 3:00 p.m. Central Time
on any Valuation Date using the Accumulation Unit Values for that Date. We will
process requests completed after 3:00 p.m. on any Valuation Date using the
Accumulation Unit Values for the next Valuation Date. The Contract permits us to
defer transfers from the Fixed Account Options for up to 6 months from the date
we receive your request. If we decide to postpone transfers from any Fixed
Account Option for 30 days or more, we will pay interest as required by
applicable law. Any interest would be payable from the date we receive the
transfer request to the date we make the transfer.

                           20     - PROSPECTUS
<PAGE>
We limit the amount you may transfer from the Standard Fixed Account Option to
any other investment alternative in any Contract Year to the greater of:

    1)  25% of the value in the Standard Fixed Account Option as of the most
        recent Contract Anniversary (if this amount is less than $1,000, then up
        to $1,000 may be transferred); or

    2)  25% of the sum of all purchase payments and transfers to the Standard
        Fixed Account Option as of the most recent Contract Anniversary.

If you transfer an amount from the Guaranteed Maturity Fixed Account Option
other than during the 30 day period after a Guarantee Period expires, we will
increase or decrease the amount by a Market Value Adjustment.

You may not transfer Contract Value into the DCA Fixed Account Option.

We reserve the right to waive any transfer restrictions.

TRANSFERS DURING THE PAYOUT PHASE
During the Payout Phase, you may make transfers among the Variable Sub-Accounts
so as to change the relative weighting of the Variable Sub-Accounts on which
your variable income payments will be based. In addition, you will have a
limited ability to make transfers from the Variable Sub-Accounts to increase the
proportion of your income payments consisting of fixed income payments. You may
not, however, convert any portion of your right to receive fixed income payments
into variable income payments.

You may not make any transfers for the first 6 months after the Payout Start
Date. Thereafter, you may make transfers among the Variable Sub-Accounts or make
transfers from the Variable Sub-Accounts to increase the proportion of your
income payments consisting of fixed income payments. Your transfers must be at
least 6 months apart.

TELEPHONE TRANSFERS
You may make transfers by telephone by calling 1-800-755-5275, if you first send
us a completed authorization form. The cut off time for telephone transfer
requests is 3:00 p.m. Central time. In the event that the New York Stock
Exchange closes early, i.e., before 3:00 p.m. Central Time, or in the event that
the Exchange closes early for a period of time but then reopens for trading on
the same day, we will process telephone transfer requests as of the close of the
Exchange on that particular day. We will not accept telephone requests received
at any telephone number other than the number that appears in this paragraph or
received after the close of trading on the Exchange.

We may suspend, modify or terminate the telephone transfer privilege at any time
without notice.

We use procedures that we believe provide reasonable assurance that the
telephone transfers are genuine. For example, we tape telephone conversations
with persons purporting to authorize transfers and request identifying
information. Accordingly, we disclaim any liability for losses resulting from
allegedly unauthorized telephone transfers. However, if we do not take
reasonable steps to help ensure that a telephone authorization is valid, we may
be liable for such losses.

DOLLAR COST AVERAGING PROGRAM
Through our Dollar Cost Averaging Program, you may automatically transfer a
fixed dollar amount every month during the Accumulation Phase from any Variable
Sub-Account, the Standard Fixed Account Option or the Dollar Cost Averaging
Fixed Account Option, to any other Variable Sub-Account. You may not use the
Dollar Cost Averaging Program to transfer amounts to a Fixed Account Option.

We will not charge a transfer fee for transfers made under this Program, nor
will such transfers count against the 12 transfers you can make each Contract
Year without paying a transfer fee.

The theory of dollar cost averaging is that if purchases of equal dollar amounts
are made at fluctuating prices, the aggregate average cost per unit will be less
than the average of the unit prices on the same purchase dates. However,
participation in this Program does not assure you of a greater profit from your
purchases under the Program nor will it prevent or necessarily reduce losses in
a declining market. Call or write us for instructions on how to enroll.

AUTOMATIC PORTFOLIO REBALANCING PROGRAM
Once you have allocated your money among the Variable Sub-Accounts, the
performance of each Sub-Account may cause a shift in the percentage you
allocated to each Sub-Account. If you select our Automatic Portfolio Rebalancing
Program, we will automatically rebalance the Contract Value in each Variable
Sub-Account and return it to the desired percentage allocations. Money allocated
to the Fixed Account Options will not be included in the rebalancing.

We will rebalance your account each quarter according to your instructions. We
will transfer amounts among

                           21     - PROSPECTUS
<PAGE>
the Variable Sub-Accounts to achieve the percentage allocations you specify. You
can change your allocations at any time by contacting us in writing or by
telephone. The new allocation will be effective with the first rebalancing that
occurs after we receive your request. We are not responsible for rebalancing
that occurs prior to receipt of your request.

Example:

    Assume that you want your initial purchase payment split among two Variable
    Sub-Accounts. You want 40% to be in the STI Investment Grade Bond Variable
    Sub-Account and 60% to be in the STI Capital Appreciation Variable
    Sub-Account. Over the next 2 months the bond market does very well while the
    stock market performs poorly. At the end of the first quarter, the STI
    Investment Grade Bond Variable Sub-Account now represents 50% of your
    holdings because of its increase in value. If you choose to have your
    holdings rebalanced quarterly, on the first day of the next quarter, we
    would sell some of your units in the STI Investment Grade Bond Variable
    Sub-Account and use the money to buy more units in the STI Capital
    Appreciation Variable Sub-Account so that the percentage allocations would
    again be 40% and 60% respectively.

The Automatic Portfolio Rebalancing Program is available only during the
Accumulation Phase. The transfers made under the Program do NOT count towards
the 12 transfers you can make without paying a transfer fee. Portfolio
rebalancing is consistent with maintaining your allocation of investments among
market segments, although it is accomplished by reducing your Contract Value
allocated to the better performing segments.

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

As a Contract owner, you will bear, directly or indirectly, the charges and
expenses described below.

CONTRACT MAINTENANCE CHARGE
During the Accumulation Phase, on each Contract Anniversary, we will deduct a
$30 contract maintenance charge from your Contract Value invested in each
Variable Sub-Account in proportion to the amount invested. If you surrender your
Contract, we will deduct the contract maintenance charge pro rated for the part
of the Contract Year elapsed, unless your Contract qualifies for a waiver,
described below. During the Payout Phase, we will deduct the charge
proportionately from each income payment.

The charge is to compensate us for the cost of administering Contracts and the
Variable Account. Maintenance costs include expenses we incur collecting
purchase payments; keeping records; processing death claims, cash withdrawals,
and policy changes; proxy statements; calculating Accumulation Unit Values and
income payments; and issuing reports to Contract owners and regulatory agencies.
We cannot increase the charge. However, we will waive this charge if:

- - total purchase payments equal $25,000 or more as of a Contract Anniversary or
  upon full withdrawal, or

- - all of your money is allocated to the Fixed Account Options on a Contract
  Anniversary.

MORTALITY AND EXPENSE RISK CHARGE
We deduct a mortality and expense risk charge daily at an annual rate of 1.25%
of the average daily net assets you have invested in the Variable Sub-Accounts
(1.35% if you select the Enhanced Death Benefit Rider, available to purchasers
after May 1, 1997). The mortality and expense risk charge is for all the
insurance benefits available with your Contract (including our guarantee of
annuity rates and the death benefits), for certain expenses of the Contract, and
for assuming the risk (expense risk) that the current charges will be sufficient
in the future to cover the cost of administering the Contract. If the charges
under the Contract are not sufficient, then we will bear the loss. We charge an
additional 0.10% for the Enhanced Death Benefit Rider to compensate us for the
additional risk that we accept by providing the rider.

We guarantee that we will not raise the mortality and expense risk charge. We
assess the mortality and expense risk charge during both the Accumulation Phase
and the Payout Phase.

ADMINISTRATIVE EXPENSE CHARGE
We deduct an administrative expense charge daily at an annual rate of 0.10% of
the average daily net assets you have invested in the Variable Sub-Accounts. We
intend this charge to cover actual administrative expenses that exceed the
revenues from the contract maintenance charge. We assess this charge each day
during the

                           22     - PROSPECTUS
<PAGE>
Accumulation Phase and the Payout Phase. We guarantee that we will not raise
this charge.

TRANSFER FEE
We do not currently impose a fee upon transfers among the investment
alternatives. However, we reserve the right to charge $10 per transfer after the
12th transfer in each Contract Year. We will NOT charge a transfer fee on
transfers that are part of a dollar cost averaging or automatic portfolio
rebalancing program.

WITHDRAWAL CHARGE
We may assess a withdrawal charge of up to 7% of the purchase payment(s) you
withdraw. The charge declines annually to 0% over a 7 year period that begins on
the day we receive your purchase payment. A schedule showing how the charge
declines appears on page 7. During each Contract Year, you can withdraw up to
10% of the Contract Value on the date of the first withdrawal in that Contract
Year without paying the charge. Unused portions of this 10% "FREE WITHDRAWAL
AMOUNT" are NOT carried forward to future Contract Years.

We will deduct withdrawal charges, if applicable, from the amount paid. For
purposes of the withdrawal charge, we will treat withdrawals as coming from the
oldest purchase payments first. However, for federal income tax purposes, please
note that withdrawals are considered to have come first from earnings in the
Contract. Thus, for tax purposes, earnings are considered to come out first,
which means you pay taxes on the earnings portion of your withdrawal.

We do not apply a withdrawal charge in the following situations:

- - on the Payout Start Date;

- - withdrawals taken to satisfy IRS minimum distribution rules for this Contract,
  or

- - withdrawals that qualify for one of the waivers described below.

We use the amounts obtained from the withdrawal charge to pay sales commissions
and other promotional or distribution expenses associated with marketing the
Contracts. To the extent that the withdrawal charge does not cover all sales
commissions and other promotional or distribution expenses, we may use any of
our corporate assets, including potential profit which may arise from the
mortality and expense risk charge or any other charges or fee described above,
to make up any difference.

Withdrawals may be subject to tax penalties or income tax and a Market Value
Adjustment. You should consult your own tax counsel or other tax advisers
regarding any withdrawals.

CONFINEMENT WAIVER. We will waive the withdrawal charge on all withdrawals taken
prior to the Payout Start Date under your Contract if the following conditions
are satisfied:

1. you or the Annuitant, if the Contract is owned by a company or other legal
entity, are confined to a long term care facility or a hospital (as defined in
the Contract) for at least 90 consecutive days. You or the Annuitant must enter
the long term care facility or hospital (as defined in the Contract) at least 30
days after the Issue Date;

2. you must request the withdrawal and provide written proof of the stay no
later than 90 days following the end of your or the Annuitant's stay at the long
term care facility or hospital (as defined in the Contract); and

3. a physician must have prescribed the stay and the stay must be medically
necessary (as defined in the Contract).

You may not claim this benefit if you or the Annuitant, or a member of your or
the Annuitant's immediate family, is the physician prescribing your or the
Annuitant's stay in a long term care facility.

TERMINAL ILLNESS WAIVER. We will waive the withdrawal charge on all withdrawals
taken prior to the Payout Start Date under your Contract if:

1. you (or the Annuitant, if the Contract owner is not a natural person) are
diagnosed by a physician (we may require a second opinion) with a terminal
illness at least 30 days after the Issue Date; and

2. you claim this benefit and deliver adequate proof of diagnosis to us.

UNEMPLOYMENT WAIVER. We will waive the withdrawal charge on one partial or a
full withdrawal taken prior to the Payout Start Date under your Contract, if you
meet the following requirements:

1. you (or the Annuitant, if the Contract owner is not a natural person) become
unemployed at least one year after the Issue Date;

2. you (or the Annuitant, if the Contract owner is not a natural person) have
been granted unemployment compensation for at least 30 consecutive days as a
result of that unemployment and we receive due proof thereof (as defined in the
Contract) prior to the time of the withdrawal request; and

3. you exercise this benefit within 180 days of your initial receipt of
unemployment compensation.

                           23     - PROSPECTUS
<PAGE>
You may exercise this benefit once during the life of your Contract.

Please refer to your Contract for more detailed information about the terms and
conditions of these waivers.

The laws of your state may limit the availability of these waivers and may also
change certain terms and/or benefits available under the waivers. You should
consult your Contract for further details on these variations. Also, even if you
do not need to pay our withdrawal charge because of these waivers, you still may
be required to pay taxes or tax penalties on the amount withdrawn. You should
consult your tax adviser to determine the effect of a withdrawal on your taxes.

PREMIUM TAXES
Some states and other governmental entities (e.g., municipalities) charge
premium taxes or similar taxes. We are responsible for paying these taxes and
will deduct them from your Contract Value. Some of these taxes are due when the
Contract is issued, others are due when income payments begin or upon surrender.
Our current practice is not to charge anyone for these taxes until income
payments begin or when a total withdrawal occurs, including payment upon death.
At our discretion, we may discontinue this practice and deduct premium taxes
from the purchase payments. Premium taxes generally range from 0% to 4%,
depending on the state.

At the Payout Start Date, we deduct the applicable charge for premium taxes from
each investment alternative in the proportion that the Contract owner's value in
the investment alternative bears to the total Contract Value.

DEDUCTION FOR SEPARATE ACCOUNT INCOME TAXES
We are not currently maintaining a provision for taxes. In the future, however,
we may maintain a provision for taxes if we determine, in our sole discretion,
that we will incur a tax as a result of the operation of the Variable Account.
We will deduct for any taxes we incur as a result of the operation of the
Variable Account, whether or not we previously made a provision for taxes and
whether or not it was sufficient. Our status under the Internal Revenue Code is
briefly described in the Statement of Additional Information.

OTHER EXPENSES
Each Portfolio deducts advisory fees and other expenses from its assets. You
indirectly bear the charges and expenses of the Portfolios whose shares are held
by the Variable Sub-Accounts. These fees and expenses are described in the
accompanying prospectuses for the Portfolios. For a summary of current estimates
of those charges and expenses, see page 7. We may receive compensation from the
investment advisers or administrators of the Portfolios in connection with
administrative services we provide to the Portfolios.

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

You can withdraw some or all of your Contract Value at any time prior to the
Payout Start Date. Withdrawals also are available under limited circumstances on
or after the Payout Start Date. See "Income Plans" on page 25.

The amount payable upon withdrawal is the Contract Value next computed after we
receive the request for a withdrawal at our headquarters, adjusted by any Market
Value Adjustment, less any withdrawal charges, contract maintenance charges,
income tax withholding, penalty tax, and any premium taxes. We will pay
withdrawals from the Variable Account within 7 days of receipt of the request,
subject to postponement in certain circumstances.

You can withdraw money from the Variable Account and/or the Fixed Account
Options. To complete a partial withdrawal from the Variable Account, we will
cancel Accumulation Units in an amount equal to the withdrawal and any
applicable withdrawal charge and premium taxes.

You must name the investment alternative from which you are taking the
withdrawal. If none is named, then the withdrawal request is incomplete and
cannot be honored.

In general, you must withdraw at least $50 at a time. You also may withdraw a
lesser amount if you are withdrawing your entire interest in a Variable Sub-
Account.

If you request a total withdrawal, we may require that you return your Contract
to us.

                           24     - PROSPECTUS
<PAGE>
POSTPONEMENT OF PAYMENTS
We may postpone the payment of any amounts due from the Variable Account under
the Contract if:

1. The New York Stock Exchange is closed for other than usual weekends or
holidays, or trading on the Exchange is otherwise restricted;

2. An emergency exists as defined by the SEC; or

3. The SEC permits delay for your protection.

In addition, we may delay payments or transfers from the Fixed Account Options
for up to 6 months (or shorter period if required by law). If we delay payment
or transfer for 30 days or more, we will pay interest as required by law.

SYSTEMATIC WITHDRAWAL PROGRAM
You may choose to receive systematic withdrawal payments on a monthly,
quarterly, semi-annual, or annual basis at any time prior to the Payout Start
Date. The minimum amount of each systematic withdrawal is $50. At our
discretion, systematic withdrawals may not be offered in conjunction with Dollar
Cost Averaging or Automatic Portfolio Rebalancing.

Depending on fluctuations in the value of the Variable Sub-Accounts and the
value of the Fixed Account Options, systematic withdrawals may reduce or even
exhaust the Contract Value. Income taxes may apply to systematic withdrawals.
Please consult your tax advisor before taking any withdrawal.

We will make systematic withdrawal payments to you or your designated payee. We
may modify or suspend the Systematic Withdrawal Program and charge a processing
fee for the service. If we modify or suspend the Systematic Withdrawal Program,
existing systematic withdrawal payments will not be affected.

MINIMUM CONTRACT VALUE
If your request for a partial withdrawal will reduce the Contract Value to less
than $2,000, we may treat it as a request for a withdrawal of your entire
Contract Value. Your Contract will terminate if you withdraw all of your
Contract Value. We will, however, ask you to confirm your withdrawal request
before terminating your Contract.

MINIMUM SURRENDER VALUE
Certain states may require us to endorse your Contract to provide a minimum
surrender value. Please refer to the endorsement for details.

INCOME PAYMENTS
- -------------------------------------------------------------------

PAYOUT START DATE
You select the Payout Start Date in your application. The Payout Start Date is
the day that money is applied to an Income Plan. The Payout Start Date must be:

- - at least one month after the Issue Date; and

- - no later than the day the Annuitant reaches age 90, or the 10th Contract
  Anniversary, if later.

You may change the Payout Start Date at any time by notifying us in writing of
the change at least 30 days before the scheduled Payout Start Date. Absent a
change, we will use the Payout Start Date stated in your Contract.

INCOME PLANS
An Income Plan is a series of scheduled payments to you or someone you
designate. You may choose and change your choice of Income Plan until 30 days
before the Payout Start Date. If you do not select an Income Plan, we will make
income payments in accordance with Income Plan 1 with guaranteed payments for 10
years.

Three Income Plans are available under the Contract. Each is available to
provide:

- - fixed income payments;

- - variable income payments; or

- - a combination of the two.

The three Income Plans are:

INCOME PLAN 1 -- LIFE INCOME WITH GUARANTEED PAYMENTS. Under this plan, we make
periodic income payments for at least as long as the Annuitant lives. If the
Annuitant dies before we have made all of the guaranteed income payments, we
will continue to pay the remainder of the guaranteed income payments.

INCOME PLAN 2 -- JOINT AND SURVIVOR LIFE INCOME WITH GUARANTEED PAYMENTS. Under
this plan, we make periodic income payments for at least as long as either the
Annuitant or the joint Annuitant is alive. If both the Annuitant and the joint
Annuitant die before we have made all of the guaranteed income payments, we will

                           25     - PROSPECTUS
<PAGE>
continue to pay the remainder of the guaranteed income payments.

INCOME PLAN 3 -- GUARANTEED PAYMENTS FOR A SPECIFIED PERIOD (5 YEARS TO 30
YEARS). Under this plan, we make periodic income payments for the period you
have chosen. These payments do not depend on the Annuitant's life. We will
deduct the mortality and expense risk charge from the Variable Account assets
supporting these payments even though we may not bear any mortality risk.

The length of any guaranteed payment period under your selected Income Plan
generally will affect the dollar amounts of each income payment. As a general
rule, longer Guarantee Periods result in lower income payments, all other things
being equal. For example, if you choose an Income Plan with payments that depend
on the life of the Annuitant but with no minimum specified period for guaranteed
payments, the income payments generally will be greater than the income payments
made under the same Income Plan with a minimum specified period for guaranteed
payments.

If you choose Income Plan 1 or 2, or, if available, another Income Plan with
payments that continue for the life of the Annuitant or joint Annuitant, we may
require proof of age and sex of the Annuitant or joint Annuitant before starting
income payments, and proof that the Annuitant or joint Annuitant is alive before
we make each payment. Please note that under such Income Plans, if you elect to
take no minimum guaranteed payments, it is possible that the payee could receive
only 1 income payment if the Annuitant and any joint Annuitant both die before
the second income payment, or only 2 income payments if they die before the
third income payment, and so on.

Generally, you may not make withdrawals after the Payout Start Date. One
exception to this rule applies if you are receiving variable income payments
that do not depend on the life of the Annuitant (such as under Income Plan 3).
In that case you may terminate all or part of the Variable Account portion of
the income payments at any time and receive a lump sum equal to the present
value of the remaining variable payments associated with the amount withdrawn.
The minimum amount you may withdraw under this feature is $1,000.

We may make other Income Plans available.

You must apply at least the Contract Value in the Fixed Account Options on the
Payout Start Date to fixed income payments. If you wish to apply any portion of
your Fixed Account Option balance to provide variable income payments, you
should plan ahead and transfer that amount to the Variable Sub-Accounts prior to
the Payout Start Date. If you do not tell us how to allocate your Contract Value
among fixed and variable income payments, we will apply your Contract Value in
the Variable Account to variable income payments and your Contract Value in the
Fixed Account Options to fixed income payments.

We will apply your Contract Value, adjusted by a Market Value Adjustment, less
applicable taxes to your Income Plan on the Payout Start Date. If the amount
available to apply under an Income Plan is less than $2,000 or not enough to
provide an initial payment of at least $20, and state law permits, we may:

- - pay you the Contract Value, adjusted by any Market Value Adjustment and less
  any applicable taxes, in a lump sum instead of the periodic payments you have
  chosen, or

- - reduce the frequency of your payments so that each payment will be at least
  $20.

VARIABLE INCOME PAYMENTS
The amount of your variable income payments depends upon the investment results
of the Variable Sub-Accounts you select, the premium taxes you pay, the age and
sex of the Annuitant, and the Income Plan you choose. We guarantee that the
payments will not be affected by (a) actual mortality experience and (b) the
amount of our administration expenses.

We cannot predict the total amount of your variable income payments. Your
variable income payments may be more or less than your total purchase payments
because (a) variable income payments vary with the investment results of the
underlying Portfolios and (b) the Annuitant could live longer or shorter than we
expect based on the tables we use.

In calculating the amount of the periodic payments in the annuity tables in the
Contract, we assumed an annual investment rate of 3%. If the actual net
investment return of the Variable Sub-Accounts you choose is less than this
assumed investment rate, then the dollar amount of your variable income payments
will decrease. The dollar amount of your variable income payments will increase,
however, if the actual net investment return exceeds the assumed investment
rate. The dollar amount of the variable income payments stays level if the net
investment return equals the assumed investment rate. Please refer to the
Statement of Additional Information for more detailed information as to how we
determine variable income payments. We reserve the right to make other assumed
investment rates available.

                           26     - PROSPECTUS
<PAGE>
FIXED INCOME PAYMENTS
We guarantee income payment amounts derived from any Fixed Account Option for
the duration of the Income Plan. We calculate the fixed income payments by:

1. adjusting the portion of the Contract Value in any Fixed Account Option on
the Payout Start Date by any applicable Market Value Adjustment;

2. deducting any applicable premium tax; and

3. applying the resulting amount to the greater of (a) the appropriate value
from the income payment table in your Contract or (b) such other value as we are
offering at that time.

We may defer making fixed income payments for a period of up to 6 months or such
shorter time period required by law. If we defer payments for 30 days or more,
we will pay interest as required by law from the date we receive the withdrawal
request to the date we make payment.

CERTAIN EMPLOYEE BENEFIT PLANS
The Contracts offered by this prospectus contain income payment tables that
provide for different payments to men and women of the same age, except in
states that require unisex tables. We reserve the right to use income payment
tables that do not distinguish on the basis of sex to the extent permitted by
law. In certain employment-related situations, employers are required by law to
use the same income payment tables for men and women. Accordingly, if the
Contract is to be used in connection with an employment-related retirement or
benefit plan and we do not offer unisex annuity tables in your state, you should
consult with legal counsel as to whether the purchase of a Contract is
appropriate.

DEATH BENEFITS
- -------------------------------------------------------------------

We will pay a death benefit if, prior to the Payout Start Date:

1. any Contract owner dies , or

2. the Annuitant dies, if the Contract owner is not a natural person.

We will pay the death benefit to the new Contract owner as determined
immediately after the death. The new Contract owner would be a surviving
Contract owner or, if none, the Beneficiary(ies).

A claim for a distribution on death must include DUE PROOF OF DEATH. We will
accept the following documentation as "Due Proof of Death":

- - a certified copy of a death certificate,

- - a certified copy of a decree of a court of competent jurisdiction as to the
  finding of death, or

- - any other proof acceptable to us.

CONTRACTS ISSUED BEFORE MAY 1, 1997

DEATH BENEFIT AMOUNT. Prior to the Payout Start Date, the death benefit before
any Market Value Adjustment is equal to the greater of:

1. the Contract Value as of the date we receive a complete request for payment
of the death benefit, or

2. for each previous DEATH BENEFIT ANNIVERSARY, the Contract Value at that
Anniversary; plus any purchase payments made since that anniversary; minus any
amounts we paid the Contract owner (including income tax we withheld from you)
since that Anniversary.

A "Death Benefit Anniversary" is every seventh Contract Anniversary beginning
with the Issue Date. For example, the Issue Date, 7th and 14th Contract
Anniversaries are the first three Death Benefit Anniversaries.

We will adjust the death benefit by any applicable Market Value Adjustment as of
the date we determine the death benefit. The death benefit will never be less
than the sum of all purchase payments less any amounts previously paid to the
Contract owner (including income tax withholding).

DEATH BENEFIT PAYMENTS. The Contract owner eligible to receive death benefits
has the following options:

1. If the Contract owner is not a natural person, then the Contract owner must
receive the death benefit in a lump sum within 5 years of the date of death.

2. Otherwise, within 60 days of the date when the death benefit is calculated,
the Contract owner may elect to receive the death benefit under an Income Plan
or in a lump sum. Payments from the Income Plan must begin within one year of
the Date of Death and must be payable throughout:

- - the life of the Contract owner; or

                           27     - PROSPECTUS
<PAGE>
- - a period not to exceed the life expectancy of the Contract owner; or

- - the life of the Contract owner with payments guaranteed for a period not to
  exceed the life expectancy of the Contract owner.

Any death benefit payable in a lump sum must be paid within five years of the
date of death. If no election is made, funds will be distributed at the end of
the 5 year period.

3. If the surviving spouse of the deceased Contract owner is the new Contract
owner, then the spouse may elect one of the options listed above or may continue
the Contract in the Accumulation Phase as if the death had not occurred. If the
Contract is continued in the Accumulation Phase, the surviving spouse may make a
single withdrawal of any amount within one year of the date of death without
incurring a withdrawal charge. However, any applicable Market Value Adjustment,
determined as of the date of the withdrawal, will apply.

CONTRACTS ISSUED ON OR AFTER
MAY 1, 1997

DEATH BENEFIT AMOUNT. Prior to the Payout Start Date, the death benefit is equal
to the greatest of:

1. the Contract Value as of the date we receive a complete request for payment
of the death benefit, or

2. the SETTLEMENT VALUE (that is, the amount payable on a full withdrawal of
Contract Value) on the date we receive a complete request for payment of the
death benefit, or

3. the Contract Value on each Death Benefit Anniversary prior to the date we
receive a complete request for payment of the death benefit, increased by
purchase payments made since that Death Benefit Anniversary and reduced by an
adjustment for any partial withdrawals since that Death Benefit Anniversary. The
adjustment is equal to (a) divided by (b) and the result multiplied by
(c) where:

    (a) is the withdrawal amount,

    (b) is the Contract Value immediately prior to the withdrawal, and

    (c) is the Contract Value on the Death Benefit Anniversary adjusted by any
        prior purchase payments or withdrawals made since that Anniversary.

We will calculate the Death Benefit Anniversary values until the oldest Contract
owner, or the Annuitant if the Contract owner is not a natural person, attains
age 80.

ENHANCED DEATH BENEFIT RIDER. For Contracts with the Enhanced Death Benefit
Rider, the death benefit will be the greatest of (1) through (3) above, or
(4) the value of the Enhanced Death Benefit Rider, which is the greatest of the
ANNIVERSARY VALUES as of the date we determine the death benefit. An
"Anniversary Value" is equal to the Contract Value on a Contract Anniversary,
increased by purchase payments made since that Anniversary and reduced by an
adjustment for any partial withdrawals since that Anniversary. The adjustment is
equal to (a) divided by (b), and the result multiplied by (c) where:

    (a) is the withdrawal amount,

    (b) is the Contract Value immediately prior to the withdrawal, and

    (c) is the Contract Value on that Contract Anniversary adjusted by any prior
        purchase payments and withdrawals since that Contract Anniversary.

We will calculate Anniversary Values for each Contract Anniversary prior to the
oldest Contract owner's or the Annuitant's, if the Contract owner is not a
natural person, 80th birthday. The Enhanced Death Benefit Rider will never be
greater than the maximum death benefit allowed by any non-forfeiture laws that
govern the Contract.

DEATH BENEFIT PAYMENTS. A death benefit will be paid:

1. if the Contract owner elects to receive the death benefit distributed in a
single payment within 180 days of the date of death, and

2. if the death benefit is paid as of the day the value of the death benefit is
determined. Otherwise, the Settlement Value will be paid. We are currently
waiving the 180 day limit, but we reserve the right to enforce the limitation in
the future.

In any event, the entire value of the Contract must be distributed within 5
years after the date of death unless an Income Plan is elected or a surviving
spouse continues the Contract in accordance with the provisions described below.

If the Contract owner eligible to receive the distribution upon death is not a
natural person, the Contract owner may elect to receive the distribution upon
death in one or more distributions.

If the Contract owner is a natural person, the Contract owner may elect to
receive the distribution upon death either in one or more distributions or by
periodic payments through an Income Plan. Payments from the

                           28     - PROSPECTUS
<PAGE>
Income Plan must begin within one year of the date of death and must be payable
throughout:

- - the life of the Contract owner; or

- - a period not to exceed the life expectancy of the Contract owner; or

- - the life of the Contract owner with payments guaranteed to a period not to
  exceed the life expectancy of the Contract owner.

If the surviving spouse of the deceased Contract owner is the new Contract
owner, then the spouse may elect one of the options listed above or may continue
the Contract in the Accumulation Phase as if the death had not occurred. If the
Contract is continued in the Accumulation Phase, the surviving spouse may make a
single withdrawal of any amount within one year of the date of death without
incurring a withdrawal charge. However, any applicable Market Value Adjustment,
determined as of the date of the withdrawal, will apply.

GLENBROOK
Glenbrook is the issuer of the Contract. Glenbrook is a stock life insurance
company organized under the laws of the State of Arizona in 1998. Previously,
Glenbrook was organized under the laws of the State of Illinois in 1992.
Glenbrook was originally organized under the laws of the State of Indiana in
1965. From 1965 to 1983 Glenbrook was known as "United Standard Life Assurance
Company" and from 1983 to 1992 as "William Penn Life Assurance Company of
America."

Glenbrook is currently licensed to operate in the District of Columbia and all
states except New York. We intend to offer the Contract in those jurisdictions
in which we are licensed and in which SunTrust Bank, Inc., through its banking
subsidiaries, conducts business. Our headquarters is located at 3100 Sanders
Road, Northbrook, Illinois, 60062.

Glenbrook is a wholly owned subsidiary of Allstate Life Insurance Company
("ALLSTATE LIFE"), a stock life insurance company incorporated under the laws of
the State of Illinois. Allstate Life is a wholly owned subsidiary of Allstate
Insurance Company, a stock property-liability insurance company incorporated
under the laws of Illinois. All of the outstanding capital stock of Allstate
Insurance Company is owned by The Allstate Corporation.

Glenbrook and Allstate Life entered into a reinsurance agreement effective
June 5, 1992. Under the reinsurance agreement, Allstate Life reinsures
substantially all of Glenbrook's liabilities under its various insurance
contracts. The reinsurance agreement provides us with financial backing from
Allstate Life. However, it does not create a direct contractual relationship
between Allstate Life and you. In other words, the obligations of Allstate Life
under the reinsurance agreement are to Glenbrook; Glenbrook remains the sole
obligor under the Contract to you.

Several independent rating agencies regularly evaluate life insurers'
claims-paying ability, quality of investments, and overall stability. A.M. Best
Company assigns A+ (Superior) to Allstate Life which automatically reinsures all
net business of Glenbrook. A.M. Best Company also assigns Glenbrook the rating
of A+(r) because Glenbrook automatically reinsures all net business with
Allstate Life. Standard & Poor's Insurance Rating Services assigns an AA+ (Very
Strong) financial strength rating and Moody's assigns an Aa2 (Excellent)
financial strength rating to Glenbrook. Glenbrook shares the same ratings of its
parent, Allstate Life. These ratings do not reflect the investment performance
of the Variable Account. We may from time to time advertise these ratings in our
sales literature.

THE VARIABLE ACCOUNT
Glenbrook established the Glenbrook Life and Annuity Company Variable Annuity
Account on December 15, 1992. We have registered the Variable Account with the
SEC as a unit investment trust. The SEC does not supervise the management of the
Variable Account or Glenbrook.

We own the assets of the Variable Account. The Variable Account is a segregated
asset account under Arizona law. That means we account for the Variable
Account's income, gains and losses separately from the results of our other
operations. It also means that only the assets of the Variable Account that are
in excess of the reserves and other Contract liabilities with respect to the
Variable Account are subject to liabilities relating to our other operations.
Our obligations arising under the Contracts are general corporate obligations of
Glenbrook.

                           29     - PROSPECTUS
<PAGE>
The Variable Account consists of 32 Variable Sub-Accounts, each of which invests
in a corresponding Portfolio. We may add new Variable Sub-Accounts or eliminate
one or more of them, if we believe marketing, tax, or investment conditions so
warrant. We do not guarantee the investment performance of the Variable Account,
its Sub-Accounts or the Portfolios. We may use the Variable Account to fund our
other annuity contracts. We will account separately for each type of annuity
contract funded by the Variable Account.

THE PORTFOLIOS

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS. We automatically reinvest all
dividends and capital gains distributions from the Portfolios in shares of the
distributing Portfolio at their net asset value.

VOTING PRIVILEGES. As a general matter, you do not have a direct right to vote
the shares of the Portfolios held by the Variable Sub-Accounts to which you have
allocated your Contract Value. Under current law, however, you are entitled to
give us instructions on how to vote those shares on certain matters. Based on
our present view of the law, we will vote the shares of the Portfolios that we
hold directly or indirectly through the Variable Account in accordance with
instructions that we receive from Contract owners entitled to give such
instructions.

As a general rule, before the Payout Start Date, the Contract owner or anyone
with a voting interest is the person entitled to give voting instructions. The
number of shares that a person has a right to instruct will be determined by
dividing the Contract Value allocated to the applicable Variable Sub-Account by
the net asset value per share of the corresponding Portfolio as of the record
date of the meeting. After the Payout Start Date, the person receiving income
payments has the voting interest. The payee's number of votes will be determined
by dividing the reserve for such Contract allocated to the applicable Variable
Sub-Account by the net asset value per share of the corresponding Portfolio. The
votes decrease as income payments are made and as the reserves for the Contract
decrease.

We will vote shares attributable to Contracts for which we have not received
instructions, as well as shares attributable to us, in the same proportion as we
vote shares for which we have received instructions, unless we determine that we
may vote such shares in our own discretion. We will apply voting instructions to
abstain on any item to be voted on a pro-rata basis to reduce the votes eligible
to be cast.

We reserve the right to vote Portfolio shares as we see fit without regard to
voting instructions to the extent permitted by law. If we disregard voting
instructions, we will include a summary of that action and our reasons for that
action in the next semi annual financial report we send to you.

CHANGES IN PORTFOLIOS. If the shares of any of the Portfolios are no longer
available for investment by the Variable Account or if, in our judgment, further
investment in such shares is no longer desirable in view of the purposes of the
Contract, we may eliminate that Portfolio and substitute shares of another
eligible investment fund. Any substitution of securities will comply with the
requirements of the Investment Company Act of 1940. We also may add new Variable
Sub-Accounts that invest in additional mutual funds. We will notify you in
advance of any change.

CONFLICTS OF INTEREST. Certain of the Portfolios sell their shares to separate
accounts underlying both variable life insurance and variable annuity contracts.
It is conceivable that in the future it may be unfavorable for variable life
insurance separate accounts and variable annuity separate accounts to invest in
the same Portfolio. The boards of directors or trustees of these Portfolios
monitor for possible conflicts among separate accounts buying shares of the
Portfolios. Conflicts could develop for a variety of reasons. For example,
differences in treatment under tax and other laws or the failure by a separate
account to comply with such laws could cause a conflict. To eliminate a
conflict, a Portfolio's board of directors or trustees may require a separate
account to withdraw its participation in a Portfolio. A Portfolio's net asset
value could decrease if it had to sell investment securities to pay redemption
proceeds to a separate account withdrawing because of a conflict.

THE CONTRACT

DISTRIBUTION. ALFS, Inc.* ("ALFS"), located at 3100 Sanders Road, Northbrook, IL
60062-7154, serves as distributor of the Contracts. ALFS is a wholly owned
subsidiary of Allstate Life Insurance Company. ALFS is a registered broker
dealer under the Securities and Exchange Act of 1934, as amended ("EXCHANGE
ACT"), and is a member of the National Association of Securities Dealers, Inc.

We will pay commissions to broker-dealers who sell the contracts. Commissions
paid may vary, but we estimate that the total commissions paid on all Contract
sales will not exceed 6% of all purchase payments (on a present value basis).
These commissions are intended to cover distribution expenses. Sometimes, we
also pay the broker-dealer a persistency bonus in addition to the

* Effective May 1, 2000, Allstate Life Financial
Services, Inc. was renamed ALFS, Inc.

                           30     - PROSPECTUS
<PAGE>
standard commissions. In some states, Contracts may be sold by representatives
or employees of banks which may be acting as broker-dealers without separate
registration under the Exchange Act, pursuant to legal and regulatory
exceptions.

Glenbrook does not pay ALFS a commission for distribution of the Contracts. The
underwriting agreement with ALFS provides that we will reimburse ALFS for any
liability to Contract owners arising out of services rendered or Contracts
issued.

ADMINISTRATION. We have primary responsibility for all administration of the
Contracts and the Variable Account. We provide the following administrative
services, among others:

- - issuance of the Contracts;

- - maintenance of Contract owner records;

- - Contract owner services;

- - calculation of unit values;

- - maintenance of the Variable Account; and

- - preparation of Contract owner reports.

We will send you Contract statements and transaction confirmations at least
quarterly. You should notify us promptly in writing of any address change. You
should read your statements and confirmations carefully and verify their
accuracy. You should contact us promptly if you have a question about a periodic
statement. We will investigate all complaints and make any necessary adjustments
retroactively, but you must notify us of a potential error within a reasonable
time after the date of the questioned statement. If you wait too long, we will
make the adjustment as of the date that we receive notice of the potential
error.

We also will provide you with additional periodic and other reports, information
and prospectuses as may be required by federal securities laws.

QUALIFIED PLANS
If you use the Contract within a qualified plan, the plan may impose different
or additional conditions or limitations on withdrawals, waivers of withdrawal
charges, death benefits, Payout Start Dates, income payments, and other Contract
features. In addition, adverse tax consequences may result if qualified plan
limits on distributions and other conditions are not met. Please consult your
qualified plan administrator for more information.

LEGAL MATTERS
Freedman, Levy, Kroll & Simonds, Washington, D.C., has advised Glenbrook on
certain federal securities law matters. All matters of state law pertaining to
the Contracts, including the validity of the Contracts and Glenbrook's right to
issue such Contracts under state insurance law, have been passed upon by Michael
J. Velotta, General Counsel of Glenbrook.

YEAR 2000
Glenbrook is heavily dependent upon complex computer systems for all phases of
its operations, including customer service, and policy and contract
administration. Since many of Glenbrook's older computer software programs
recognize only the last two digits of the year in any date, some software may
have failed to operate properly in or after the year 1999, if the software was
not reprogrammed or replaced ("YEAR 2000 ISSUE"). Glenbrook believes that many
of its counterparties and suppliers also had potential Year 2000 Issues which
could affect Glenbrook. In 1995, Allstate Insurance Company commenced a four
phase plan intended to mitigate and/or prevent the adverse effects of Year 2000
Issues. These strategies included normal development and enhancement of new and
existing systems, upgrades to operating systems already covered by maintenance
agreements and modifications to existing systems to make them Year 2000
compliant. The plan also included Glenbrook actively working with its major
external counterparties and suppliers to assess their compliance efforts and
Glenbrook's exposure to them. Because of the accuracy of this plan, and its
timely completion, Glenbrook has experienced no material impacts on its results
of operations, liquidity or financial position due to the Year 2000 issue. Year
2000 costs are expensed as incurred.

TAXES
- -------------------------------------------------------------------

THE FOLLOWING DISCUSSION IS GENERAL AND IS NOT INTENDED AS TAX ADVICE. GLENBROOK
MAKES NO GUARANTEE REGARDING THE TAX TREATMENT OF ANY CONTRACT OR TRANSACTION
INVOLVING A CONTRACT.

Federal, state, local and other tax consequences of ownership or receipt of
distributions under an annuity contract depend on your individual circumstances.
If you are concerned about any tax consequences with

                           31     - PROSPECTUS
<PAGE>
regard to your individual circumstances, you should consult a competent tax
adviser.

TAXATION OF ANNUITIES IN GENERAL

TAX DEFERRAL. Generally, you are not taxed on increases in the Contract Value
until a distribution occurs. This rule applies only where:

1. the Contract owner is a natural person,

2. the investments of the Variable Account are "adequately diversified"
according to Treasury Department regulations, and

3. Glenbrook is considered the owner of the Variable Account assets for federal
income tax purposes.

NON-NATURAL OWNERS. As a general rule, annuity contracts owned by non-natural
persons such as corporations, trusts, or other entities are not treated as
annuity contracts for federal income tax purposes. The income on such contracts
is taxed as ordinary income received or accrued by the owner during the taxable
year. Please see the Statement of Additional Information for a discussion of
several exceptions to the general rule for Contracts owned by non-natural
persons.

DIVERSIFICATION REQUIREMENTS. For a Contract to be treated as an annuity for
federal income tax purposes, the investments in the Variable Account must be
"adequately diversified" consistent with standards under Treasury Department
regulations. If the investments in the Variable Account are not adequately
diversified, the Contract will not be treated as an annuity contract for federal
income tax purposes. As a result, the income on the Contract will be taxed as
ordinary income received or accrued by the Contract owner during the taxable
year. Although Glenbrook does not have control over the Portfolios or their
investments, we expect the Portfolios to meet the diversification requirements.

OWNERSHIP TREATMENT. The IRS has stated that you will be considered the owner of
Variable Account assets if you possess incidents of ownership in those assets,
such as the ability to exercise investment control over the assets. At the time
the diversification regulations were issued, the Treasury Department announced
that the regulations do not provide guidance concerning circumstances in which
investor control of separate account investments may cause an investor to be
treated as the owner of the separate account. The Treasury Department also
stated that future guidance would be issued regarding the extent that owners
could direct sub-account investments without being treated as owners of the
underlying assets of the separate account.

Your rights under the Contract are different than those described by the IRS in
rulings in which it found that contract owners were not owners of separate
account assets. For example, you have the choice to allocate premiums and
Contract Values among more investment alternatives. Also, you may be able to
transfer among investment alternatives more frequently than in such rulings.
These differences could result in you being treated as the owner of the Variable
Account. If this occurs, income and gain from the Variable Account assets would
be includible in your gross income. Glenbrook does not know what standards will
be set forth in any regulations or rulings which the Treasury Department may
issue. It is possible that future standards announced by the Treasury Department
could adversely affect the tax treatment of your Contract. We reserve the right
to modify the Contract as necessary to attempt to prevent you from being
considered the federal tax owner of the assets of the Variable Account. However,
we make no guarantee that such modification to the Contract will be successful.

TAXATION OF PARTIAL AND FULL WITHDRAWALS. If you make a partial withdrawal under
a non-Qualified Contract, amounts received are taxable to the extent the
Contract Value, without regard to surrender charges, exceeds the investment in
the Contract. The investment in the Contract is the gross premium paid for the
Contract minus any amounts previously received from the Contract if such amounts
were properly excluded from your gross income. If you make a partial withdrawal
under a Qualified Contract, the portion of the payment that bears the same ratio
to the total payment that the investment in the Contract (i.e., nondeductible
IRA contributions, after tax contributions to qualified plans) bears to the
Contract Value, is excluded from your income. If you make a full withdrawal
under a non-Qualified Contract or a Qualified Contract, the amount received will
be taxable only to the extent it exceeds the investment in the Contract.

"Non-qualified distributions" from Roth IRAs are treated as made from
contributions first and are included in gross income only to the extent that
distributions exceed contributions. "Qualified distributions" from Roth IRAs are
not included in gross income. "Qualified distributions" are any distributions
made more than 5 taxable years after the taxable year of the first contribution
to any Roth IRA and which are:

- - made on or after the date the individual attains age 59 1/2,

- - made to a beneficiary after the Contract owner's death,

- - attributable to the Contract owner being disabled, or

                           32     - PROSPECTUS
<PAGE>
- - for a first time home purchase (first time home purchases are subject to a
  lifetime limit of $10,000).

If you transfer a non-Qualified Contract without full and adequate consideration
to a person other than your spouse (or to a former spouse incident to a
divorce), you will be taxed on the difference between the Contract Value and the
investment in the Contract at the time of transfer. Except for certain Qualified
Contracts, any amount you receive as a loan under a Contract, and any assignment
or pledge (or agreement to assign or pledge) of the Contract Value is treated as
a withdrawal of such amount or portion.

TAXATION OF ANNUITY PAYMENTS. Generally, the rule for income taxation of annuity
payments received from a non-Qualified Contract provides for the return of your
investment in the Contract in equal tax-free amounts over the payment period.
The balance of each payment received is taxable. For fixed annuity payments, the
amount excluded from income is determined by multiplying the payment by the
ratio of the investment in the Contract (adjusted for any refund feature or
period certain) to the total expected value of annuity payments for the term of
the Contract. If you elect variable annuity payments, the amount excluded from
taxable income is determined by dividing the investment in the Contract by the
total number of expected payments. The annuity payments will be fully taxable
after the total amount of the investment in the Contract is excluded using these
ratios. If you die, and annuity payments cease before the total amount of the
investment in the Contract is recovered, the unrecovered amount will be allowed
as a deduction for your last taxable year.

TAXATION OF ANNUITY DEATH BENEFITS. Death of a Contract owner, or death of the
Annuitant if the Contract is owned by a non-natural person, will cause a
distribution of death benefits from a Contract. Generally, such amounts are
included in income as follows:

1. if distributed in a lump sum, the amounts are taxed in the same manner as a
full withdrawal; or

2. if distributed under an annuity option, the amounts are taxed in the same
manner as an annuity payment. Please see the Statement of Additional Information
for more detail on distribution at death requirements.

PENALTY TAX ON PREMATURE DISTRIBUTIONS. A 10% penalty tax applies to the taxable
amount of any premature distribution from a Non-Qualified Contract. The penalty
tax generally applies to any distribution made prior to the date you attain age
59 1/2. However, no penalty tax is incurred on distributions:

1. made on or after the date the Contract owner attains age 59 1/2;

2. made as a result of the Contract owner's death or disability;

3. made in substantially equal periodic payments over the Contract owner's life
or life expectancy;

4. made under an immediate annuity; or

5. attributable to investment in the Contract before August 14, 1982.

You should consult a competent tax advisor to determine if any other exceptions
to the penalty apply to your situation. Similar exceptions may apply to
distributions from Qualified Contracts.

AGGREGATION OF ANNUITY CONTRACTS. All non-qualified deferred annuity contracts
issued by Glenbrook (or its affiliates) to the same Contract owner during any
calendar year will be aggregated and treated as one annuity contract for
purposes of determining the taxable amount of a distribution.

TAX QUALIFIED CONTRACTS
The income on qualified plan and IRA investments is tax-deferred and variable
annuities held by such plans do not receive any additional tax-deferral. You
should review the annuity features, including all benefits and expenses, prior
to purchasing a variable annuity in a qualified plan. Glenbrook reserves the
right to limit the availability of the Contract for use with any of the
Qualified Plans listed below.

Contracts may be used as investments with certain qualified plans such as:

- - Individual Retirement Annuities or Accounts (IRAs) under Section 408 of the
  Internal Revenue Code ("Code");

- - Roth IRAs under Section 408A of the Code;

- - Simplified Employee Pension Plans under Section 408(k) of the Code;

- - Savings Incentive Match Plans for Employees (SIMPLE) Plans under Section
  408(p) of the Code;

- - Tax Sheltered Annuities under Section 403(b) of the Code;

- - Corporate and Self Employed Pension and Profit Sharing Plans; and

- - State and Local Government and Tax-Exempt Organization Deferred Compensation
  Plans.

In the case of certain qualified plans, the terms of the plans may govern the
right to benefits, regardless of the terms of the Contract.

                           33     - PROSPECTUS
<PAGE>
RESTRICTIONS UNDER SECTION 403(b) PLANS. Section 403(b) of the Code provides
tax-deferred retirement savings plans for employees of certain non-profit and
educational organizations. Under Section 403(b), any Contract used for a
403(b) plan must provide that distributions attributable to salary reduction
contributions made after 12/31/88, and all earnings on salary reduction
contributions, may be made only:

1. on or after the date the employee

  - attains age 59 1/2,

  - separates from service,

  - dies,

  - becomes disabled, or

2. on account of hardship (earnings on salary reduction contributions may not be
distributed on the account of hardship).

These limitations do not apply to withdrawals where Glenbrook is directed to
transfer some or all of the Contract Value to another 403(b) plan.

INCOME TAX WITHHOLDING
Glenbrook is required to withhold federal income tax at a rate of 20% on all
"eligible rollover distributions" unless you elect to make a "direct rollover"
of such amounts to an IRA or eligible retirement plan. Eligible rollover
distributions generally include all distributions from Qualified Contracts,
excluding IRAs, with the exception of:

1. required minimum distributions, or

2. a series of substantially equal periodic payments made over a period of at
least 10 years, or, over the life (joint lives) of the participant (and
beneficiary).

Glenbrook may be required to withhold federal and state income taxes on any
distributions from non-Qualified Contracts or Qualified Contracts that are not
eligible rollover distributions, unless you notify us of your election to not
have taxes withheld.

PERFORMANCE INFORMATION
- -------------------------------------------------------------------

We may advertise the performance of the Variable Sub-Accounts, including yield
and total return information. Yield refers to the income generated by an
investment in a Variable Sub-Account over a specified period. Total return
represents the change, over a specified period of time, in the value of an
investment in a Variable Sub-Account after reinvesting all income distributions.

All performance advertisements will include, as applicable, standardized yield
and total return figures that reflect the deduction of insurance charges, the
contract maintenance charge, and withdrawal charge. Performance advertisements
also may include total return figures that reflect the deduction of insurance
charges, but not the contract maintenance or withdrawal charges. The deduction
of such charges would reduce the performance shown. In addition, performance
advertisements may include aggregate average, year-by-year, or other types of
total return figures.

Performance information for periods prior to the inception date of the Variable
Sub-Accounts will be based on the historical performance of the corresponding
Portfolios for the periods beginning with the inception dates of the Portfolios
and adjusted to reflect current Contract expenses. You should not interpret
these figures to reflect actual historical performance of the Variable Account.

We may include in advertising and sales materials tax deferred compounding
charts and other hypothetical illustrations that compare currently taxable and
tax deferred investment programs based on selected tax brackets. Our
advertisements also may compare the performance of our Variable Sub-Accounts
with: (a) certain unmanaged market indices, including but not limited to the Dow
Jones Industrial Average, the Standard & Poor's 500, and the Shearson Lehman
Bond Index; and/or (b) other management investment companies with investment
objectives similar to the underlying funds being compared. In addition, our
advertisements may include the performance ranking assigned by various
publications, including the Wall Street Journal, Forbes, Fortune, Money,
Barron's, Business Week, USA Today, and statistical services, including Lipper
Analytical Services Mutual Fund Survey, Lipper Annuity and Closed End Survey,
the Variable Annuity Research Data Survey, and SEI.

APPENDIX B
MARKET VALUE ADJUSTMENT
- -------------------------------------------------------------------

The Market Value Adjustment is based on the following:

 I   =   the interest crediting rate for a Guarantee Period

 N   =   the number of whole and partial years from the date we receive the
         transfer, withdrawal, or death benefit request, or from the Payout
         Start Date to the end of the Guarantee Period; and

 J   =   the current interest crediting rate offered for a Guarantee Period of
         length N on the date we determine the Market Value Adjustment.

         J will be determined by a linear interpolation between the current
         interest rates for the next higher and lower integral years. For
         purposes of interpolation, current interest rates for Guarantee
         Periods not available under this Contract will be calculated in a
         manner consistent with those which are available.

The Market Value Adjustment factor is determined from the following formula:

                                .9 X (I - J) X N

Any transfer, withdrawal, or death benefit (depending on your Contract) paid or
amount applied to an Income Plan from a Guarantee Period (except during the 30
day period after such Guarantee Period expires) will be multiplied by the Market
Value Adjustment factor to determine the Market Value Adjustment.

that Registrant will indemnify its officers and directors for certain damages
and expenses that may be incurred in the performance of their duty to
Registrant. No indemnification is provided, however, when such person is
adjudged to be liable for negligence or misconduct in the performance of his or
her duty, unless indemnification is deemed appropriate by the court upon
application.

ITEM 17.  UNDERTAKINGS.

The undersigned registrant hereby undertakes:

<PAGE>

(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to the registration statement:

         (i)   To include any  prospectus  required  by section  10(a)(3) of the
               Securities Act of 1933;

         (ii)  To reflect in the prospectus any facts or events arising after
               the effective date of the registration statement (or the most
               recent post-effective amendment thereof ) which, individually or
               in the aggregate, represent a fundamental change in the
               information set forth in the registration statement; and

         (iii) to include any material information with respect to the plan of
               distribution not previously disclosed in the registration
               statement or any material change to such information in the
               registration statement;

(2) That, for the purpose of determining any liability under the Securities Act
of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;

(3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant, Glenbrook Life and Annuity Company, pursuant to the foregoing
provisions, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
