(1) The management fee is 0.625% for net assets of up to $500 million. For net
    assets which exceed $500 million, but do not exceed $1 billion, the
    management fee is 0.50% and for net assets that exceed $1 billion, the
    management fee is 0.475%.
 
(2) This percentage is applicable to Portfolio net assets of up to $500 million.
    For net assets which exceed $500 million, the management fee is 0.55%.
 
(3) This percentage is applicable to Portfolio net assets of up to $500 million.
    For net assets which exceed $500 million, the management fee is 0.45%.
 
   
(4) A portion of the brokerage commissions the fund paid was used to reduce its
    expenses. With this reduction, total operating expenses were (for High
    Income: 0.71% and Contrafund 0.72% [please note - there were brokerage
    commissions paid, but they did not affect these ratios]).
    
 
(5) The Dreyfus Corporation has undertaken, until December 31, 1996, that if the
    aggregate expenses of the Fund, exclusive of taxes, brokerage, interest on
    borrowings and (with the prior written consent of the necessary state
    securities commissions) extraordinary expenses, but including the management
    fee, exceed 1.00 of 1% of the value of the Fund's average daily net assets,
    the Fund may deduct from the payment to be made to Dreyfus under the
    management agreement, or Dreyfus will bear, such excess expense.
 
(6) The Dreyfus Corporation has undertaken, until December 31, 1996, that if the
    aggregate expenses of the Portfolio, exclusive of taxes, brokerage, interest
    on borrowings and (with the prior written consent of the necessary state
    securities commissions) extraordinary expenses, but including the management
    fee, exceed 1.25 of 1% of the value of the Portfolio's average daily net
    assets, the Portfolio may deduct from the payment to be made to Dreyfus
    under the management agreement, or Dreyfus will bear, such excess expense.
    The Total Fund Expense is an annualized figure based off of actual expenses
    incurred during the period from inception (May 1, 1996) to June 30, 1996.
 
(7) Total Fund Annual Expenses reflect expense reimbursements for The Dreyfus
    Socially Responsible Growth Fund, Inc., VIF Small Company Stock, VIF Growth
    & Income, and VIF Money Market Portfolios of 0.06%, 0.20%, 0.03% and 0.03%
    respectively.
 
(8) The Adviser has agreed to bear, subject to reimbursement, expenses for each
    of the Emerging Growth Series and Limited Maturity Series such that each
    Series' aggregate operating expenses shall not exceed, on an annual basis,
    1.00% of the average daily net assets of the Series from November 2, 1994
    through December 31, 1996, 1.25% of the average daily net assets of the
    Series from January 1, 1997 through December 31, 1998, and 1.50% of the
    average daily net assets of the Series from January 1, 1999 through December
    31, 2004; provided however, that this obligation may be terminated or
    revised at any time. See "Information Concerning Shares of Each Series --
    Expenses" below. Absent this expense arrangement, "Other Expenses" for the
    Emerging Growth Series and Limited Maturity Series would be 2.16% and 1.00%
    respectively, and "Total Operating Expenses" would be 2.91% and 1.55%
    respectively, for these Series. 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 and may enter into other such arrangements and directed brokerage
    arrangements (which would also have the effect of reducing the Series'
    expenses). Any such fee reductions are not reflected under "Other Expenses."

CONDENSED FINANCIAL INFORMATION
 
Condensed financial information for the Glenbrook Life Multi-Manager Variable
Account is not included because, as of the date of this prospectus, the Variable
Account had not yet commenced operations and had no assets, liabilities, or
income.
 
YIELD AND TOTAL RETURN DISCLOSURE
 
From time to time the Variable Account may advertise the yield and total return
investment performance of one or more Sub-accounts. Yield and standardized total
return advertisements include all charges and expenses attributable to the
Contracts. Including these fees has the effect of decreasing the advertised
performance of a Sub-account, so that a Sub-account's investment performance
will not be directly comparable to that of an ordinary mutual fund.
 
When a Sub-account advertises its standardized total return it will be
calculated for one year, five years, and ten years or since inception if the
Sub-account has not been in existence for such periods. Total return is measured
by comparing the value of an investment in the Sub-account at the end of the
relevant period to the value of the investment at the beginning of the period.
 
In addition to the standardized total return, the Sub-account may advertise a
non-standardized total return. This figure may be calculated for one year, five
years, and ten years or other periods. Non-standardized total return is measured
in the same manner as the standardized total return described above, except that
the withdrawal charges under the Contract are not deducted. Therefore, a
non-standardized total return for a Sub-account can be higher than a
standardized total return for a Sub-account.
 
Certain Sub-accounts may advertise yield in addition to total return. Except in
the case of the Money Market Sub-account, the yield will be computed in the
following manner: the net investment income per unit earned during a recent one
month period is divided by the unit value on the last day of the period, and
then annualized. This figure reflects the recurring charges at the separate
account level.
 
The Money Market Sub-account may advertise, in addition to the total return,
either yield or the effective yield. The yield in this case refers to the income
generated by an investment in that Sub-account over a seven-day period net of
recurring charges at the separate account level. The income is then annualized
(i.e., the amount of income generated by the investment during that week is
assumed to be generated each week over a 52-week period and is shown as a
percentage of the investment). The effective yield is calculated similarly but
when annualized, the income earned by an investment in the Money Market
Sub-account is assumed to be reinvested at the end of each seven-day period. The
effective yield will be slightly higher than the yield because of the
compounding effect of this assumed reinvestment during a 52-week period.
 
The Variable Account may also disclose yield, standard total return, and
non-standard total return for periods prior to the date that the Variable
Account commenced operations. For periods prior to the date the Variable Account
commenced operations, performance information for the Sub-accounts will be
calculated based on the performance of the underlying Portfolios and the
assumption that the Sub-accounts were in existence for the same periods as those
of the underlying Portfolios, with a level of charges equal to those currently
assessed against the Sub-accounts.
 
Please refer to the Statement of Additional Information for a further
description of the method used to calculate a Sub-account's yield and total
return.

THE VARIABLE ACCOUNT
 
Established on January 15, 1996, the Glenbrook Life Multi-Manager Variable
Account is a unit investment trust registered with the Securities and Exchange
Commission under the Investment Company Act of 1940. However, such registration
does not signify that the Commission supervises the management or investment
practices or policies of the Variable Account. The investment performance of the
Variable Account is entirely independent of both the investment performance of
the Company's general account and the performance of any other separate account.
 
The Variable Account has been divided into fifteen Sub-accounts, each of which
invests solely in its corresponding Portfolio of the Funds. Additional Variable
Sub-accounts may be added at the discretion of the Company.
 
The assets of the Variable Account are held separately from the other assets of
the Company. They are not chargeable with liabilities incurred in the Company's
other business operations. Accordingly, the income, capital gains and capital
losses, realized or unrealized, incurred on the assets of the Variable Account
are credited to or charged against the assets of the Variable Account, without
regard to the income, capital gains or capital losses arising out of any other
business the Company may conduct. The Company's obligations arising under the
Contracts are general corporate obligations of the Company.
 
THE FUNDS
 
The Variable Account will invest in shares of one or more Funds. The Funds are
registered with the Securities and Exchange Commission as open-end, series,
management investment companies. Registration of the Funds does not involve
supervision of their management, investment practices or policies by the

CONCERNING THE ALLOCATION OF PURCHASE PAYMENTS TO A PARTICULAR VARIABLE

FIXED ACCOUNT OPTIONS
 
DOLLAR COST AVERAGING FIXED ACCOUNT
 
Purchase payments allocated to the Dollar Cost Averaging Fixed Account become
part of the general account of the Company, which supports insurance and annuity
obligations. The general account consists of the general assets of the Company
other than those in segregated asset accounts.
 
Instead of you bearing the investment risk, as is the case for amounts in the
Variable Account or in other segregated asset accounts of the Company, we bear
the investment risk for all amounts in the Dollar Cost Averaging Fixed Account.
We have sole discretion to invest the assets of the Dollar Cost Averaging Fixed
Account, subject to applicable law. We guarantee that the amounts allocated to
the Dollar Cost Averaging Fixed Account will be credited interest at a net
effective annual interest rate at least equal to the minimum guaranteed rate
found in the Contract. Currently, the amount of interest credited in excess of
the guaranteed rate will vary periodically at the sole discretion of the
Company. Any interest held in the Dollar Cost Averaging Fixed Account does not
entitle an Owner to share in the investment experience of the general account.
 
Money allocated to the Dollar Cost Averaging Fixed Account earns interest for a
one year period at the current rate in effect at the time of allocation. After
the one year period, a renewal rate will be declared. Subsequent renewal dates
will be every twelve months for each payment. The renewal interest rate will be
guaranteed by us for a full year and will not be less than the minimum
guaranteed rate found in the Contract. We may declare more than one interest
rate for different monies based upon the date of allocation to the Dollar Cost
Averaging Fixed Account. Any interest credited to amounts allocated to the
Dollar Cost Averaging Fixed Account in excess of the guaranteed rate found in
the Contract will be determined at the sole discretion of the Company.
 
Purchase payments may be allocated to the Dollar Cost Averaging Fixed Account
for the purpose of establishing a Dollar Cost Averaging Program. Each purchase
payment and all its earnings must be transferred out of the Dollar Cost
Averaging Fixed Account via Dollar Cost Averaging within 36 months of the
payment. At the end of 36 months, any remaining payment and associated earnings
will be transferred to the Money Market portfolio.
 
Surrenders and withdrawals from the Dollar Cost Averaging Fixed Account may be
delayed for up to six months.
 
Interests in the Dollar Cost Averaging Fixed Account are not registered with the
Securities and Exchange Commission ("SEC") and the SEC does not review
disclosure related to or supervise the operations of this account.
 
GUARANTEED MATURITY FIXED ACCOUNT
 
Purchase payments and transfers allocated to one or more of the Sub-accounts of
the Guaranteed Maturity Fixed Account become part of the general account of the
Company. Each Sub-account offers a separate interest rate Guarantee Period.
Guarantee Periods will be offered at the Company's discretion and may range from
one to ten years. Presently, the Company offers Guarantee Periods of one, three,
five, seven and ten years. The Owner must select the Sub-account(s) to which to
allocate each purchase payment and transfer. No less than $50 may be allocated
to any one Sub-account. The Company reserves the right to limit the number of
additional purchase payments. The Guaranteed Maturity Fixed Account option may
not be available in all states. Please consult with your sales representative
for current information.
 
Interest is credited daily to each Sub-account at a rate which compounds to the
effective annual interest rate declared for each Sub-account's Guarantee Period
that has been selected.

TOTAL INTEREST CREDITED IN GUARANTEE PERIOD:  $2,611.60 ($12,611.60 -
$10,000.00)
 
NOTE: The above illustration assumes no withdrawals of any amount during the
entire five year period. A withdrawal charge and a Market Value Adjustment may
apply to any amount withdrawn in excess of 15% of the amount of purchase
payments. The hypothetical interest rate is for illustrative purposes only and
is not intended to predict future interest rates to be declared under the
Contract.
 
The Company has no specific formula for determining the rate of interest that it
will declare initially or in the future. Such interest rates will be reflective
of investment returns available at the time of the determination. In addition,
the management of the Company may also consider various other factors in
determining interest rates, including regulatory and tax requirements, sales
commissions and administrative expenses borne by the Company, general economic
trends, and competitive factors. For current interest rate information, please
contact your sales representative or the Company's customer support unit at
1(800)755-5275.
 
THE MANAGEMENT OF THE COMPANY WILL MAKE THE FINAL DETERMINATION AS TO THE
INTEREST RATES TO BE DECLARED. THE COMPANY CAN NEITHER PREDICT NOR GUARANTEE
FUTURE INTEREST RATES TO BE DECLARED.
 
At the end of a Guarantee Period, a notice will be mailed to the Owner outlining
the options available at the end of a Guarantee Period. During the 30 day period
after a Guarantee Period expires the Owner may:
 
    - take no action and the Company will automatically renew the Sub-account
      value to a Guarantee Period of the same duration to be established as of
      the day the previous Guarantee Period expired; or
 
    - notify the Company to apply the Sub-account value to a new Guarantee
      Period or periods to be established as of the day the previous Guarantee
      Period expired; or
 
    - notify the Company to apply the Sub-account value to any Sub-account of
      the Variable Account on the day we receive the notification; or
<PAGE>
14
 
    - receive a portion of the Sub-account value or the entire Sub-account value
      through a partial or full withdrawal that is not subject to a Market Value
      Adjustment. In this case, the amount withdrawn will be deemed to have been
      renewed at the shortest Guarantee Period then being offered with current
      interest credited from the date the Guarantee Period expired.
 
The Automatic Laddering Program allows the Owner to choose, in advance, one
renewal Guarantee Period for all renewing Sub-accounts. The Owner can select the
Automatic Laddering Program at any time during the accumulation phase, including
on the issue date. The Automatic Laddering Program will continue until the Owner
gives written notice to the Company. The Company reserves the right to
discontinue this Program. For additional information on the Automatic Laddering
Program, please call the Company's Customer Support Unit at 1(800)755-5275.
 
WITHDRAWALS OR TRANSFERS
 
Withdrawals in excess of the free withdrawal amount and transfers, paid from a
Sub-account of the Guaranteed Maturity Fixed Account other than during the 30
day period after a Guarantee Period expires are subject to a Market Value
Adjustment. See "Market Value Adjustment" section on page   for additional
details.
 
The amount received by the Owner under a withdrawal request equals the amount
requested, adjusted by any Market Value Adjustment, less any applicable
withdrawal charge (based upon the amount requested prior to any Market Value
Adjustment), less premium taxes and withholding (if applicable), less any
applicable transfer fee.
 
MARKET VALUE ADJUSTMENT
 
The Market Value Adjustment reflects the relationship between (1) the Treasury
Rate for the original Guarantee Period at the time of the request for withdrawal
or transfer, and (2) the Treasury Rate for the original Guarantee Period at the
time the Sub-account was established. As such, the Owner bears some investment
risk under the Contract. Treasury Rate means the U.S. Treasury Note Constant
Maturity yield for the preceding week as reported in Federal Reserve Bulletin
Release H.15.
 
Generally, if the Treasury Rate at the time the Sub-account was established is
higher than the applicable current Treasury Rate, then the Market Value
Adjustment will result in a higher amount payable to the Owner or transferred.
Similarly, if the Treasury Rate at the time the Sub-account was established is
lower than the applicable current Treasury Rate (interest rate for a period
equal to the original Guarantee Period), then the Market Value Adjustment will
result in a lower amount payable to the Owner or transferred.
 
For example, assume the Owner purchases a Contract and selects an initial
Guarantee Period of five years and the five year Treasury Rate for that duration
is 4.75%. Assume that at the end of 3 years, the Owner makes a partial
withdrawal. If, at that later time, the current five year Treasury Rate is
4.00%, then the Market Value Adjustment will be positive, which will result in
an increase in the amount payable to the Owner. Similarly, if the current five
year Treasury Rate is 7.00%, then the Market Value Adjustment will be negative,
which will result in a decrease in the amount payable to the Owner.
 
The formula for calculating the Market Value Adjustment is set forth in Appendix
A to this prospectus, which also contains additional illustrations of the
application of the Market Value Adjustment.
 
PURCHASE OF THE CONTRACTS
 
PURCHASE PAYMENT LIMITS
 
Your first purchase payment must be at least $3,000 unless the Contract is a
Qualified Contract, in which case the first purchase payment must be at least
$2,000. All subsequent purchase payments must be $50 or more and may be made at
any time prior to the Payout Start Date. We may limit your ability to make
subsequent purchase payments in order to comply with the laws of the state where
this Contract is delivered. Subsequent purchase payments may also be made from
your bank account through Automatic Additions. The minimum purchase payment for
allocation to the Dollar Cost Averaging Fixed Account or any Sub-account of the
Guaranteed Maturity Fixed Account is $50. Please consult with your sales
representative for detailed information about Automatic Additions.
 
We reserve the right to limit the maximum amount of purchase payments we will
accept.
 
FREE-LOOK PERIOD
 
You may cancel the Contract any time within 20 days after receipt of the
Contract, or longer if required by state law, and receive a full refund of
purchase payments allocated to the Fixed Account Options. Purchase payments
allocated to the Variable Account will be returned after an adjustment to
reflect investment gain or loss that occurred from the date of allocation
through the date of cancellation unless a refund of purchase payments is
required by state or federal law.

CREDITING OF INITIAL PURCHASE PAYMENT
 
The initial purchase payment accompanied by a duly completed application will be
credited to the Contract within two business days of receipt by us at our home
office. If an application is not duly completed, we will credit the purchase
payments to the Contract within five business days or return it at that time
unless you specifically consent to us holding the purchase payment until the
application is complete. We reserve the right to reject any application.
Subsequent purchase payments will be credited to the Contract at the close of
the Valuation Period in which the purchase payment is received by the Company at
its home office.
 
ALLOCATION OF PURCHASE PAYMENTS
 
On the application, you instruct us how to allocate the purchase payment among
the Investment Alternatives. Purchase payments may be allocated in whole
percents, from 0% to 100% (total allocation equals 100% of the purchase
payment), or in whole dollar amounts (total allocation equals the purchase
payment), to any Investment Alternative. Unless you notify us in writing
otherwise, subsequent purchase payments are allocated according to the
allocation for the previous purchase payment. Any change in allocation
instructions will be effective at the time we receive the notice in good order.
 
ACCUMULATION UNITS
 
Each purchase payment allocated to the Variable Account will be credited to the
Contract as Accumulation Units. For example, if a $10,000 purchase payment is
credited to the Contract when the Accumulation Unit value equals $10, then 1,000
Accumulation Units would be credited to the Contract. The Variable Account, in
turn, purchases shares of the corresponding Portfolio.
 
ACCUMULATION UNIT VALUE
 
The Accumulation Units in each Sub-account of the Variable Account are valued
separately. The value of Accumulation Units will change each Valuation Period
according to the investment performance of the shares purchased by each Variable
Sub-account and the deduction of certain expenses and charges.
 
The value of an Accumulation Unit in a Variable Sub-account for any Valuation
Period equals the value of the Accumulation Unit as of the immediately preceding
Valuation Period, multiplied by the Net Investment Factor for that Sub-account
for the current Valuation Period. The Net Investment Factor for a Valuation
Period is a number representing the change, since the last Valuation Date in the
value of Sub-account assets per Accumulation Unit due to investment income,
realized or unrealized capital gain or loss, deductions for taxes, if any, and
deductions for the mortality and expense risk charge and administrative expense
charge.
 
TRANSFERS AMONG INVESTMENT ALTERNATIVES
 
Amounts may be transferred among Investment Alternatives, subject to the
following restrictions. The Company reserves the right to assess a $10 charge on
each transfer in excess of twelve per Contract Year. The Company is presently
waiving this charge. Transfers to or from more than one Investment Alternative
on the same day are treated as one transfer.
 
   
Transfers among Investment Alternatives before the Payout Start Date may be made
at any time. After the Payout Start Date, if the Income Plan depends on any
person's life, transfers among Sub-accounts of the Variable Account or from a
variable amount income payment to a fixed amount income payment may be made only
once every six months and may not be made during the first six months following
the Payout Start Date. After the Payout Start Date, if the Income Plan does not
depend on any person's life, transfers among Sub-accounts of the Variable
Account or from a variable amount income payment to a fixed amount income
payment may be made immediately. After the Payout Start Date, transfers from a
fixed amount income payment are not allowed.
    
 
Telephone transfer requests will be accepted by the Company if received at
1(800)755-5275 by 3:00 p.m., Central Time. Telephone transfer requests received
at any other telephone number or after 3:00 p.m., Central Time will not be
accepted by the Company. Telephone transfer requests received before 3:00 p.m.,
Central Time are effected at the next computed value. The Company utilizes
procedures which the Company believes will provide reasonable assurance that
telephone authorized transfers are genuine. Such procedures include taping of
telephone conversations with persons purporting to authorize such transfers and
requesting identifying information from such persons. Accordingly, the Company
disclaims any liability for losses resulting from such transfers by reason of
their allegedly not having been properly authorized. However, if the Company
does not take reasonable steps to help ensure that such authorizations are
valid, the Company may be liable for such losses.
 
The minimum amount that may be transferred into a Sub-account of the Guaranteed
Maturity Fixed Account is $50. No transfers are allowed into the Dollar Cost
Averaging Fixed Account. Any transfer from a Sub-account of the Guaranteed
Maturity Fixed Account at a time other than
<PAGE>
16
during the 30 day period after a Guarantee Period expires will be subject to a
Market Value Adjustment.
 
The Company reserves the right to waive transfer restrictions.
 
DOLLAR COST AVERAGING
 
Transfers may be made automatically through Dollar Cost Averaging prior to the
Payout Start Date. Dollar Cost Averaging permits the Owner to transfer a
specified amount every month from the Dollar Cost Averaging Fixed Ac-
count or the Money Market Sub-account, to any Sub-account of the Variable
Account. Dollar Cost Averaging cannot be used to transfer amounts to the
Guaranteed Maturity Fixed Account. In addition, such transfers are not assessed
a $10 charge and are not included in the twelve free transfers per Contract
Year.
 
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 the Dollar Cost Averaging program does not assure you of a
greater profit from your purchases under the program; nor will it prevent or
alleviate losses in a declining market.
 
AUTOMATIC PORTFOLIO REBALANCING
 
Transfers may be made automatically through Automatic Portfolio Rebalancing
prior to the Payout Start Date. By electing Automatic Portfolio Rebalancing, all
of the money allocated to Sub-accounts of the Variable Account will be
rebalanced to the desired allocation on a quarterly basis, determined from the
first date that you decide to rebalance. Each quarter, money will be transferred
among Sub-accounts of the Variable Account to achieve the desired allocation.
 
The desired allocation will be the allocation initially selected, unless
subsequently changed. You may change the allocation at any time by giving us
written notice. The new allocation will be effective with the first rebalancing
that occurs after we receive the written request. We are not responsible for
rebalancing that occurs prior to receipt of the written request.
 
Transfers made through Automatic Portfolio Rebalancing are not assessed a $10
charge and are not included in the twelve free transfers per Contract Year.
 
Any money allocated to the Fixed Account Options will not be included in the
rebalancing.
 
BENEFITS UNDER THE CONTRACT
 
WITHDRAWALS
 
You may withdraw all or part of the Contract Value at any time prior to the
earlier of the death of the Owner (or the Annuitant if the Owner is not a
natural person) or the Payout Start Date. The amount available for withdrawal is
the Contract Value next computed after the Company receives the request for a
withdrawal at its home office, adjusted by any applicable Market Value
Adjustment, less any applicable withdrawal charges, contract maintenance
charges, income tax withholding, penalty tax and premium taxes. Withdrawals from
the Variable Account will be paid within seven days of receipt of the request,
subject to postponement in certain circumstances. See "Delay of Payments," page
  .
 
Money can be withdrawn from the Variable Account or the Fixed Account. To
complete the partial withdrawal from the Variable Account, the Company will
redeem Accumulation Units in an amount equal to the withdrawal and any
applicable withdrawal charge and premium taxes. The Owner must name the
Investment Alternative from which the withdrawal is to be made. If none is
named, then the withdrawal request is incomplete and cannot be honored.
 
The minimum partial withdrawal is $50. If the Contract Value after a partial
withdrawal would be less than $2,000, then the Company will treat the request as
one for termination of the Contract and the entire Contract Value, adjusted by
any Market Value Adjustment, less any charges and premium taxes, will be paid
out.
 
Partial withdrawals may also be taken automatically through Systematic
Withdrawals on a monthly, quarterly, semi-annual or annual basis. Systematic
Withdrawals of $50 or more may be requested at any time prior to the Payout
Start Date. At the Company's discretion, Systematic Withdrawals may not be
offered in conjunction with Dollar Cost Averaging or Automatic Portfolio
Rebalancing.
 
Partial and full withdrawals may be subject to income tax and a 10% tax penalty.
This tax and penalty are explained in "Federal Tax Matters," on page   .
 
After the Payout Start Date, withdrawals are only permitted when payments from
the Variable Account are being made that do not involve life contingencies. In
that case, you may terminate the Variable Account portion of the income payments
at any time and receive a lump sum equal to the commuted balance of the
remaining variable payments due, less any applicable withdrawal charge.
<PAGE>

INCOME PAYMENTS
 
PAYOUT START DATE FOR INCOME PAYMENTS
 
The Payout Start Date is the day that income payments will start under the
Contract. You may change the Payout Start Date at any time by notifying the
Company in writing of the change at least 30 days before the scheduled Payout
Start Date. The Payout Start Date must be (a) at least one month after the issue
date; and (b) no later than the day the Annuitant reaches age 90, or the 10th
anniversary of the issue date, if later.
 
VARIABLE ACCOUNT INCOME PAYMENTS
 
The amount of Variable Account income payments depends upon the investment
experience of the Sub-accounts selected by the Owner and any premium taxes, the
age and sex of the Annuitant, and the Income Plan chosen. The Company guarantees
that the amount of the income payment will not be affected by (1) actual
mortality experience and (2) the amount of the Company's administration
expenses.
 
The Contracts offered by this prospectus contain income payment tables that
provide for different benefit payments to men and women of the same age (except
in states which require unisex annuity tables). Nevertheless, in accordance with
the U.S. Supreme Court's decision in ARIZONA GOVERNING COMMITTEE V. NORRIS, in
certain employment-related situations, annuity tables that do not vary on the
basis of sex will be used.
 
The total income payments received may be more or less than the total purchase
payments made because (a) Variable Account income payments vary with the
investment results of the underlying Portfolios, and (b) Annuitants may not live
as long as, or may live longer than, expected.
 
The Income Plan option selected will affect the dollar amount of each income
payment. For example, if an Income Plan for a Life Income is chosen, the income
payments will be greater than income payments under an Income Plan for a Life
Income with Guaranteed Payments.
 
If the actual net investment experience of the Variable Account is less than the
assumed investment rate, then the dollar amount of the income payments will
decrease. The dollar amount of the income payments will stay level if the net
investment experience equals the assumed investment rate and the dollar amount
of the income payments will increase if the net investment experience exceeds
the assumed investment rate. For purposes of the Variable Account income
payments, the assumed investment rate is 3 percent. For more detailed
information as to how Variable Account income payments are determined, see the
Statement of Additional Information.
 
FIXED AMOUNT INCOME PAYMENTS
 
Income payment amounts derived from any monies allocated to any Fixed Account
Option are guaranteed for the duration of the Income Plan. The income payment
based upon any fixed amount income payment is calculated by applying the portion
of the Contract Value in any Fixed Account Option on the Payout Start Date,
adjusted by any Market Value Adjustment and less any applicable premium tax, to
the greater of the appropriate value from the income payment table selected or
such other value as we are offering at that time.
 
INCOME PLANS
 
The Income Plans include:
 
    INCOME PLAN 1 -- LIFE INCOME WITH GUARANTEED PAYMENTS
 
    The Company will make payments for as long as the Annuitant lives. If the
    Annuitant dies before the selected number of guaranteed payments have been
    made, the Company will continue to pay the remainder of the guaranteed
    payments.
 
    INCOME PLAN 2 -- JOINT AND SURVIVOR LIFE INCOME WITH GUARANTEED PAYMENTS
 
    The Company will make payments for as long as either the Annuitant or Joint
    Annuitant, named at the time of Income Plan selection, is living. If both
    the Annuitant and the Joint Annuitant die before the selected number of
    guaranteed payments have been made, the Company will continue to pay the
    remainder of the guaranteed payments.
 
    INCOME PLAN 3 -- GUARANTEED NUMBER OF PAYMENTS
 
    The Company will make payments for a specified number of months beginning on
    the Payout Start Date. These payments do not depend on the Annuitant's life.
    The number of months guaranteed may be from 60 to 360. The mortality and
    expense risk charge will be deducted from Variable Account assets supporting
    these payments even though the Company does not bear any mortality risk.
 
The Owner may change the Income Plan until 30 days before the Payout Start Date.
If an Income Plan is chosen which depends on the Annuitant or Joint Annuitant's
life, proof of age will be required before income payments begin. Applicable
premium taxes will be assessed.
<PAGE>
18
 
In the event that an Income Plan is not selected, the Company will make income
payments in accordance with Income Plan 1 with Guaranteed Payments for 120
Months. At the Company's discretion, other Income Plans may be available upon
request. The Company currently uses sex-distinct annuity tables. However, if
legislation is passed by Congress or the states, the Company reserves the right
to use income payment tables which do not distinguish on the basis of sex.
Special rules and limitations may apply to certain qualified contracts.
 
If the Contract Value to be applied to an Income Plan is less than $2,000, or if
the monthly payments determined under the Income Plan are less than $20, the
Company may pay the Contract Value adjusted by any Market Value Adjustment and
less any applicable taxes, in a lump sum or change the payment frequency to an
interval which results in income payments of at least $20.
 
DEATH BENEFITS
 
DISTRIBUTION UPON DEATH PAYMENT PROVISIONS
 
A distribution upon death may be paid to the Owner determined immediately after
the death if, prior to the Payout Start Date:
 
    - any Owner dies; or
 
    - the Annuitant dies and the Owner is not a natural person.
 
If the Owner eligible to receive a distribution upon death is not a natural
person, then the Owner may elect to receive the distribution upon death in one
or more distributions. Otherwise, if the Owner is a natural person, the Owner
may elect to receive a distribution upon death in one or more distributions or
periodic payments through an Income Plan.
 
A death benefit will be paid: 1) if the Owner elects to receive the death
benefit in a single payment distributed 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. The settlement
value is the same amount that would be paid in the event of withdrawal of the
Contract Value. The Company will calculate the settlement value at the end of
the Valuation Period coinciding with the requested distribution date for payment
or on the mandatory distribution date of 5 years after the date of death. In any
event, the entire distribution upon death must be distributed within five years
after the date of death unless a surviving spouse continues the Contract or an
Income Plan is selected in accordance with the following sections:
 
Payments from the Income Plan must begin within one year of the date of death
and must be payable throughout:
 
    - the life of the Owner; or
 
    - a period not to exceed the life expectancy of the Owner; or
 
    - the life of the Owner with payments guaranteed for a period not to exceed
      the life expectancy of the Owner.
 
If the surviving spouse of the deceased Owner is the new 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. The Company will only
permit the Contract to be continued once. 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.
 
DEATH BENEFIT AMOUNT
 
Prior to the Payout Start Date, the standard death benefit is equal to the
greatest of:
 
    (a) the Contract Value on the date the Company determines the death benefit;
        or
 
    (b) the Settlement Value on the date the Company determines the death
        benefit; or
 
    (c) the Contract Value on each Death Benefit Anniversary prior to the date
        the Company determines the death benefit adjusted by any purchase
        payments, withdrawals* and charges made between such Death Benefit
        Anniversary and the date the Company determines the death benefit. 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.
 
For Contracts with the optional enhanced death benefit provision, the death
benefit will be the greater of (a) through (c) above, or (d) below:
 
    (d) the greatest of the anniversary values as of the date the Company
        determines the death benefit. The 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
<PAGE>
19
        for any partial withdrawals* since that anniversary. Anniversary values
        will be calculated for each Contract Anniversary prior to the earlier
        of: (i) the date we determine the death benefit, or (ii) the oldest
        Owner's or the Annuitant's, if the Owner is not a natural person,
        attained age 80.
 
* The adjustment for withdrawals is equal to the Contract Value on a Death
Benefit Anniversary or Contract Anniversary multiplied by the ratio of the
withdrawal amount to the Contract Value immediately prior to the to the
withdrawal.
 
The value of the death benefit will be determined at the end of the Valuation
Period during which the Company receives a complete request for payment of the
death benefit, which includes due proof of death.
 
The Company will not settle any death claim until it receives due proof of
death.
 
CHARGES AND OTHER DEDUCTIONS
 
DEDUCTIONS FROM PURCHASE PAYMENTS
 
No deductions are made from purchase payments. Therefore, the full amount of
every purchase payment is invested in the Investment Alternative(s).
 
WITHDRAWAL CHARGE (CONTINGENT DEFERRED SALES CHARGE)
 
You may withdraw the Contract Value at any time before the earliest of the
Payout Start Date, the death of any Owner or, if the Owner is not a natural
person, the death of the Annuitant.
 
There are no withdrawal charges on amounts withdrawn up to 15% of the amount of
purchase payments. Amounts withdrawn in excess of this may be subject to a
withdrawal charge. Amounts not subject to a withdrawal charge and not withdrawn
in a Contract Year are not carried over to later Contract Years. Withdrawal
charges, if applicable, will be deducted from the amount paid.
 
For purposes of calculating the amount of the withdrawal charge, withdrawals are
assumed to come from purchase payments first, beginning with the oldest payment.
Withdrawals made after all purchase payments have been withdrawn, will not be
subject to a withdrawal charge. For partial withdrawals, the Contract Value will
be adjusted to reflect the amount of payment requested by the Owner, any
withdrawal charge, any applicable taxes and any Market Value Adjustment.
 
Withdrawals in excess of the free withdrawal amount will be subject to a
withdrawal charge as set forth below:

</TABLE>
 
Withdrawal charges will be used to pay sales commissions and other promotional
or distribution expenses associated with the marketing of the Contracts. The
Company does not anticipate that the withdrawal charges will cover all
distribution expenses in connection with the Contract.
 
In addition, federal and state income tax may be withheld from withdrawal
amounts. Certain terminations may also be subject to a federal tax penalty. See
"Federal Tax Matters," page .
 
The Company will waive any withdrawal charge prior to the Payout Start Date if
1) at least 30 days after the Contract Date any Owner (or Annuitant if the Owner
is not a natural person) is first confined to a long term care facility or
hospital for at least 90 consecutive days, confinement is prescribed by a
physician and is medically necessary, and the request for a withdrawal and
adequate written proof of confinement are received by us no later than 120 days
after discharge or 2) any Owner (or Annuitant if the Owner is not a natural
person) is diagnosed with a terminal illness. The withdrawal charge will also be
waived on withdrawals taken to satisfy IRS required minimum distribution rules.
This waiver is permitted only for withdrawals which satisfy distributions
resulting from this Contract. If applicable, such withdrawals will be subject to
a Market Value Adjustment.
 
CONTRACT MAINTENANCE CHARGE
 
A contract maintenance charge is deducted annually from the Contract Value to
reimburse the Company for its actual costs in maintaining each Contract and the
Variable Account. The Company guarantees that the amount of this charge will not
exceed $35 per Contract Year over the life of the Contract. Prior to the Payout
Start Date, this charge will be waived if the total purchase payments are
$50,000 or more on a Contract Anniversary or if all money is allocated to the
Fixed Account on the Contract Anniversary. After the Payout Start Date, this
charge will be waived if total purchase payments are $50,000 or more as of the
Payout Start Date.
<PAGE>
20
 
Maintenance costs include but are not limited to expenses incurred in billing
and collecting purchase payments; keeping records; processing death claims, cash
withdrawals, and policy changes; proxy statements; calculating Accumulation Unit
and Annuity Unit values; and issuing reports to Owners and regulatory agencies.
The Company does not expect to realize a profit from this charge.
 
On each Contract Anniversary prior to the Payout Start Date, the contract
maintenance charge will be deducted from Sub-accounts of the Variable Account in
the same proportion that the Owner's value in each bears to the Owner's total
value in all Sub-accounts of the Variable Account. After the Payout Start Date,
a pro rata share of the annual contract maintenance charge will be deducted from
each income payment. For example, 1/12 of the $35, or $2.92, will be deducted if
there are twelve income payments during the Contract Year. A pro-rated contract
maintenance charge will be deducted if the Contract is terminated on any date
other than a Contract Anniversary.
 
ADMINISTRATIVE EXPENSE CHARGE
 
The Company will deduct an administrative expense charge which is equal, on an
annual basis, to .10% of the daily net assets the Owner has allocated to the
Sub-accounts of the Variable Account. This charge is designed to cover actual
administrative expenses which exceed the revenues from the contract maintenance
charge. The Company does not intend to profit from this charge. The Company
believes that the administrative expense charge and contract maintenance charge
have been set at a level that will recover no more than the actual costs
associated with administering the Contracts. There is no necessary relationship
between the amount of administrative charge imposed on a given Contract and the
amount of expenses that may be attributable to that Contract.
 
MORTALITY AND EXPENSE RISK CHARGE
 
The Company will deduct a mortality and expense risk charge which is equal, on
an annual basis, to 1.25% of the daily net assets you have allocated to the
Sub-accounts of the Variable Account. The Company estimates that .80% is
attributable to the assumption of mortality risks and .45% is attributable to
the assumption of expense risks. For Contracts with the optional enhanced death
benefit provision, the mortality and expense risk charge will be deducted daily,
at a rate equal on an annual basis to 1.35% of the daily net assets in the
Variable Account. The assessment of the additional .10% for the enhanced death
benefit is attributed to the assumption of additional mortality risks. The
Company guarantees that the percentage for this charge will not increase over
the life of the Contract.
 
The mortality risk arises from the Company's guarantee to cover all death
benefits and to make income payments in accordance with the Income Plan selected
and the Income Payment Tables.
 
The expense risk arises from the possibility that the contract maintenance and
administrative expense charge, both of which are guaranteed not to increase,
will be insufficient to cover actual administrative expenses.
 
If the mortality and expense risk charge is insufficient to cover the Company's
mortality costs and excess expenses, the Company will bear the loss. If the
charge is more than sufficient, the Company will retain the balance as profit.
The Company currently expects a profit from this charge. Any such profit, as
well as any other profit realized by the Company and held in its general account
(which supports insurance and annuity obligations), would be available for any
proper corporate purpose, including, but not limited to, payment of distribution
expenses.
 
TAXES
 
The Company will deduct applicable state premium taxes or other similar
policyholder taxes relative to the Contract (collectively referred to as
"premium taxes") either at the Payout Start Date, or when a total withdrawal
occurs. Current premium tax rates range from 0 to 3.5%. The Company reserves the
right to deduct premium taxes from the purchase payments.
 
At the Payout Start Date, the charge for premium taxes will be deducted from
each Investment Alternative in the proportion that the Owner's value in the
Investment Alternative bears to the total Contract Value.
 
TRANSFER CHARGES
 
The Company reserves the right to assess a $10 charge on each transfer in excess
of twelve per Contract Year, excluding transfers through Dollar Cost Averaging
and Automatic Portfolio Rebalancing. The Company is presently waiving this
charge.
 
FUND EXPENSES

found in the prospectuses for the Funds. This prospectus is accompanied by the

GENERAL MATTERS
 
OWNER
 
The Owner has the sole right to exercise all rights and privileges under the
Contract, except as otherwise provided in the Contract. The Contract cannot be
jointly owned by both a non-natural person and a natural person.
 
BENEFICIARY
 
Subject to the terms of any irrevocable Beneficiary designation, the Owner may
change the Beneficiary at any time by notifying the Company in writing. Any
change will be effective at the time it is signed by the Owner, whether or not
the Owner is living when the change is received by the Company. The Company will
not, however, be liable as to any payment or settlement made prior to receiving
the written notice.
 
Unless otherwise provided in the Beneficiary designation, if a Beneficiary
predeceases the Owner and there are no other surviving beneficiaries or if the
Owner does not name a Beneficiary, the new Beneficiary will be: the Owner's
spouse if living; otherwise, the Owner's children, equally, if living;
otherwise, the Owner's estate. Multiple Beneficiaries may be named. Unless
otherwise provided in the Beneficiary designation, if more than one Beneficiary
survives the Owner, the surviving Beneficiaries will share equally in any
amounts due.
 
ASSIGNMENTS
 
The Company will not honor an assignment of an interest in a Contract as
collateral or security for a loan. Otherwise, the Owner may assign benefits
under the Contract prior to the Payout Start Date. No Beneficiary may assign
benefits under the Contract until they are due. No assignment will bind the
Company unless it is signed by the Owner and filed with the Company. The Company
is not responsible for the validity of an 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.
 
DELAY OF PAYMENTS
 
Payment of any amounts due from the Variable Account under the Contract will
occur within seven days, unless:
 
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 Securities and Exchange Commission; or
 
3.  The Securities and Exchange Commission permits delay for the protection of
    the Owners.
 
Payments or transfers from the Fixed Account may be delayed for up to 6 months.
If payment or transfer is delayed for 30 days or more, the Company will pay
interest as required by applicable law.
 
MODIFICATION
 
The Company may not modify the Contract without the consent of the Owner except
to make the Contract meet the requirements of the Investment Company Act of
1940, or to make the Contract comply with any changes in the Internal Revenue
Code or to make any changes required by the Code or by any other applicable law.
 
CUSTOMER INQUIRIES
 
The Owner or any persons interested in the Contract may make inquiries regarding
the Contract by calling or writing your representative or the Company at:

FEDERAL TAX MATTERS
 
INTRODUCTION
 
THE FOLLOWING DISCUSSION IS GENERAL AND IS NOT INTENDED AS TAX ADVICE. THE
COMPANY 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 the individual circumstances of each person. If you are concerned
about any tax consequences with regard to your individual circumstances, you
should consult a competent tax adviser.
 
TAXATION OF ANNUITIES IN GENERAL
 
TAX DEFERRAL
 
Generally, an annuity contract owner is not taxed on increases in the Contract
Value until a distribution occurs. This rule applies only where (1) the owner is
a natural
<PAGE>
22
person, (2) the investments of the Variable Account are "adequately diversified"
in accordance with Treasury Department Regulations, and (3) the issuing
insurance company, instead of the annuity owner, is considered the owner for
federal income tax purposes of any separate account assets funding the contract.
 
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 and the income on such contracts is taxed as
ordinary income received or accrued by the owner during the taxable year. There
are several exceptions to the general rule for contracts owned by non-natural
persons which are discussed in the Statement of Additional Information.
 
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" in
accordance with the standards provided in the Treasury regulations. If the
investments in the Variable Account are not adequately diversified, then the
Contract will not be treated as an annuity contract for federal income tax
purposes and the Owner will be taxed on the excess of the Contract Value over
the investment in the Contract. Although the Company does not have control over
the Portfolios or their investments, the Company expects the Portfolios to meet
the diversification requirements.
 
OWNERSHIP TREATMENT
 
In connection with the issuance of the regulations on the adequate
diversification standards, the Department of the Treasury announced that the
regulations do not provide guidance concerning the extent to which contract
owners may direct their investments among Sub-accounts of a variable account.
The Internal Revenue Service has previously stated in published rulings that a
variable contract owner will be considered the owner of separate account assets
if the owner possesses 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, Treasury announced that guidance would
be issued in the future regarding the extent that owners could direct their
investments among Sub-accounts without being treated as owners of the underlying
assets of the Variable Account. As of the date of this prospectus, no such
guidance has been issued.
 
The ownership rights under this contract are similar to, but different in
certain respects from, those described by the Service in rulings in which it was
determined that contract owners were not owners of separate account assets. For
example, the owner of this contract has the choice of more investment options to
which to allocate premiums and contract values, and may be able to transfer
among investment options more frequently than in such rulings. These differences
could result in the contract owner being treated as the owner of the assets of
the Variable Account. In those circumstances, income and gains from the Variable
Account assets would be includible in the Contract Owners' gross income. In
addition, the Company does not know what standards will be set forth in the
regulations or rulings which the Treasury Department has stated it expects to
issue. It is possible that Treasury's position, when announced, may adversely
affect the tax treatment of existing contracts. The Company, therefore, reserves
the right to modify the Contract as necessary to attempt to prevent the Owner
from being considered the federal tax owner of the assets of the Variable
Account. However, the Company makes no guarantee that such modification to the
contract will be successful.
 
DELAYED MATURITY DATES
 
If the contract's scheduled maturity date is at a time when the annuitant has
reached an advanced age, e.g., past age 85, it is possible that the contract
would not be treated as an annuity. In that event, the income and gains under
the contract could be currently includible in the owner's income.
 
TAXATION OF PARTIAL AND FULL WITHDRAWALS
 
In the case of a partial withdrawal under a non-qualified contract, amounts
received are taxable to the extent the contract value before the withdrawal
exceeds the investment in the contract. The investment in the contract is the
gross premium or other consideration paid for the contract reduced by any
amounts previously received from the contract to the extent such amounts were
properly excluded from the owner's gross income. In the case of 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, can be excluded from income. In the case of 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. If an individual transfers an annuity contract without full and
adequate consideration to a person other than the individual's
<PAGE>
23
spouse (or to a former spouse incident to a divorce), the owner will be taxed on
the difference between the contract value and the investment in the contract at
the time of transfer. Other than in the case of certain qualified contracts, any
amount received 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. The contract provides a death benefit that in certain
circumstances may exceed the greater of the payments and the contract value. As
described elsewhere in the prospectus, the Company imposes certain charges with
respect to the death benefit. It is possible that some portion of those charges
could be treated for federal tax purposes as a partial withdrawal from the
contract.
 
TAXATION OF ANNUITY PAYMENTS
 
Generally, the rule for income taxation of payments received from an annuity
contract provides for the return of the owner's investment in the contract in
equal tax-free amounts over the payment period. The balance of each payment
received is taxable. In the case of 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. In the case of 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. Once the total amount of the investment in the
contract is excluded using these ratios, the annuity payments will be fully
taxable. If annuity payments cease because of the death of the annuitant before
the total amount of the investment in the contract is recovered, the unrecovered
amount generally will be allowed as a deduction to the annuitant for his last
taxable year.
 
TAXATION OF ANNUITY DEATH BENEFITS
 
Amounts may be distributed from an annuity contract because of the death of an
owner or annuitant. Generally, such amounts are includible 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.
 
PENALTY TAX ON PREMATURE DISTRIBUTIONS
 
There is a 10% penalty tax on the taxable amount of any premature distribution
from a non-qualified annuity contract. The penalty tax generally applies to any
distribution made prior to the owner attaining age 59 1/2. However, there should
be no penalty tax on distributions to owners (1) made on or after the owner
attains age 59 1/2; (2) made as a result of the owner's death or disability; (3)
made in substantially equal periodic payments over life or life expectancy; (4)
made under an immediate annuity; or (5) attributable to an investment in the
contract before August 14, 1982. Similar rules apply for distributions under
certain qualified contracts. A competent tax advisor should be consulted to
determine if any other exceptions to the penalty apply to your specific
circumstances.
 
AGGREGATION OF ANNUITY CONTRACTS
 
All non-qualified deferred annuity contracts issued by the Company (or its
affiliates) to the same 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
 
Annuity contracts may be used as investments with certain tax qualified plans
such as: (1) Individual Retirement Annuities under Section 408(b) of the Code;
(2) Simplified Employee Pension Plans under Section 408(k) of the Code; (3) Tax
Sheltered Annuities under Section 403(b) of the Code; (4) Corporate and Self
Employed Pension and Profit Sharing Plans; and (5) State and Local Government
and Tax-Exempt Organization Deferred Compensation Plans. In the case of certain
tax qualified plans, the terms of the plans may govern the right to benefits,
regardless of the terms of the contract.
 
RESTRICTIONS UNDER SECTION 403(B) PLANS
 
Section 403(b) of the Code provides for tax-deferred retirement savings plans
for employees of certain non-profit and educational organizations. In accordance
with the requirements of Section 403(b), any annuity 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 after the employee attains age 59 1/2, separates
from service, dies, becomes disabled or 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 the Company is
directed to transfer some or all of the contract value to another Section 403(b)
plans.
<PAGE>

INCOME TAX WITHHOLDING
 
The Company is required to withhold federal income tax at a rate of 20% on all
"eligible rollover distributions" unless an individual elects to make a "direct
rollover" of such amounts to another qualified plan or Individual Retirement
Account or Annuity (IRA). 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 the life (joint
lives) of the participant (and beneficiary). For any distributions from non-
qualified annuity contracts, or distributions from qualified contracts which are
not considered eligible rollover distributions, the Company may be required to
withhold federal and state income taxes unless the recipient elects not to have
taxes withheld and properly notifies the Company of such election.
 
DISTRIBUTION OF THE CONTRACTS
 
Allstate Life Financial Services, Inc. ("ALFS"), 3100 Sanders Road, Northbrook
Illinois, a wholly owned subsidiary of Allstate Life, acts as the principal
underwriter of the Contracts. ALFS is registered as a broker-dealer under the
Securities Exchange Act of 1934 and became a member of the National Association
of Securities Dealers, Inc. on June 30, 1993. Contracts are sold by registered
representatives of broker-dealers or bank employees who are licensed insurance
agents appointed by the Company, either individually or through an incorporated
insurance agency. 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 Securities Exchange Act of 1934, pursuant to legal and
regulatory exceptions.
 
Commissions paid may vary, but in aggregate are not anticipated to exceed 6.50%
of any purchase payment. In addition, under certain circumstances, certain
sellers of the Contracts may be paid persistency bonuses which will take into
account, among other things, the length of time purchase payments have been held
under a Contract, and Contract Values. A persistency bonus is not expected to
exceed 0.25%, on an annual basis, of the Contract Values considered in
connection with the bonus. These commissions are intended to cover distribution
expenses. In addition, sale of the Contract may count toward incentive program
awards for the registered representative.
 
The underwriting agreement with ALFS provides for indemnification of ALFS by the
Company for liability to Owners arising out of services rendered or Contracts
issued.
 
VOTING RIGHTS
 
The Owner or anyone with a voting interest in the Sub-account of the Variable
Account may instruct the Company on how to vote at shareholder meetings of the
Fund. The Company will solicit and cast each vote according to the procedures
set up by the Fund and to the extent required by law. The Company reserves the
right to vote the eligible shares in its own right, if subsequently permitted by
the Investment Company Act of 1940, its regulations or interpretations thereof.
 
Fund shares as to which no timely instructions are received will be voted in
proportion to the voting instructions which are received with respect to all
Contracts participating in that Sub-account. Voting instructions to abstain on
any item to be voted upon will be applied on a pro-rata basis to reduce the
votes eligible to be cast.
 
Before the Payout Start Date, the Owner holds the voting interest in the
Sub-account of the Variable Account. (The number of votes for the Owner will be
determined by dividing the Contract Value attributable to a Sub-account by the
net asset value per share of the applicable eligible Portfolio.)
 
After the Payout Start Date, the person receiving income payments has the voting
interest. After the Payout Start Date, the votes decrease as income payments are
made and as the reserves for the Contract decrease. That person's number of
votes will be determined by dividing the reserve for such Contract allocated to
the applicable Sub-account by the net asset value per share of the corresponding
eligible Portfolio.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
The following highlights significant factors influencing results of operations
and financial position.
 
Glenbrook Life and Annuity Company ("the Company"), which is wholly owned by
Allstate Life Insurance Company ("Allstate Life"), currently issues flexible
premium fixed annuities, and beginning in 1995, flexible premium deferred
variable annuity contracts through its separate accounts. The Company markets
its products through banks and other financial institutions.
 
The Company reinsures all of its annuity deposits with Allstate Life, and all
life insurance in-force with other reinsurers. Accordingly, the financial
results reflected in the Company's statements of operations relate only to the
investment of those assets of the Company that are not transferred to Allstate
Life or other reinsurers under the reinsurance treaties.
 
Separate account assets and liabilities are legally segregated and carried at
fair value in the statements of financial position. The separate account
investment portfolios were initially funded with a $10 million seed money
contribution from the Company in 1995. Investment income and realized gains and
losses of the separate account investments, other than the portion related to
the Company's participation, accrue directly to the contractholders (net of
fees) and, therefore, are not included in the Company's statements of
operations.

</TABLE>
 
Net investment income increased $2.0 million in 1995, and $1.3 million in 1994.
In both years, the increases were attributable to an increased level of
investments, including the Company's participation in the separate accounts
during 1995, and a $40 million capital contribution received from Allstate Life
in the third quarter of 1994. Net income increases of $1.6 million and $0.8
million reflect the change in net investment income in both years.
 
   
Realized capital gains after tax of $0.3 million in 1995 were the result of
sales of investments to fund the Company's participation in the separate
accounts.

- ---------------
(1)  Unrealized net capital gains (losses) exclude the effect of deferred income
    taxes.
 
Fixed income securities are classified as available for sale and carried in the
statements of financial position at fair value. Although the Company generally
intends to hold its fixed income securities for the long-term, such
classification affords the Company flexibility in managing the portfolio in
response to changes in market conditions.
 
At December 31, 1995 unrealized capital gains were $5.2 million compared to
unrealized capital losses of $1.7 million at December 31, 1994. The significant
change in the unrealized capital gain/loss position is primarily attributable to
declining interest rates.
 
At December 31, 1995 both contractholder funds and amounts recoverable from
Allstate Life under reinsurance treaties reflect an increase of $644 million.
These increases result from sales of the Company's single and flexible premium
deferred annuities partially offset by surrenders. Reinsurance recoverable from
Allstate Life relates to policy benefit obligations ceded to Allstate Life.
 
   
The Company's participation in the separate accounts of $10.5 million at
December 31, 1995 is included in the separate accounts' assets. Unrealized net
capital gains arising from the Company's participation in the separate accounts
was $0.3 million, net of tax, at December 31, 1995.

LIQUIDITY AND CAPITAL RESOURCES
 
   
Allstate Life made a $40 million capital contribution to the Company in the
third quarter of 1994.
    
Under the terms of intercompany reinsurance agreements, assets of the Company
that relate to insurance in-force, excluding separate account assets, are
transferred to Allstate Life or other reinsurers, who maintain investment
portfolios which support the Company's products.
 
   
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE QUARTER ENDED JUNE 30, 1996
    
 
GENERAL
 
The following highlights significant factors influencing results of operations
and changes in financial position of Glenbrook Life and Annuity Company (the
"Company"). It should be read in conjunction with the discussion and analysis
and financial statements thereto found under Items 7 and 8 of Part II of the
Glenbrook Life and Annuity Company Annual Report on Form 10-K.
 
The Company, which is wholly owned by Allstate Life Insurance Company ("Allstate
Life"), issues flexible premium fixed annuity contracts, indexed annuity
contracts and single premium life insurance policies. In addition, the Company
issues flexible premium deferred variable annuity contracts, the assets and
liabilities of which are legally segregated and reflected in the accompanying
statements of financial position as the assets and liabilities of the Separate
Accounts. The Company markets its products through banks and other financial
institutions.
 
The Company reinsures substantially all of its annuity deposits with Allstate
Life, and all life insurance in force with other unaffiliated reinsurers.
Accordingly, the financial results reflected in the Company's statements of
operations do not include income related to those assets that are transferred to
Allstate Life or other reinsurers under the reinsurance treaties.
 
   
Separate account assets and liabilities are carried at fair value in the
statements of financial position. Certain separate account investment portfolios
established in 1995 were initially funded with a $10 million seed money
contribution from the Company in 1995. Investment income and realized gains and
losses of the separate account investments, other than the portion related to
the Company's participation, accrue directly to the contractholders (net of
fees) and, therefore, are not included in the Company's statements of
operations.

Pre-tax net investment income decreased 7.9% to $941 thousand for the second
quarter of 1996 compared to $1,022 thousand for the same period in 1995 and
decreased 7.6% to $1,864 thousand for the first six months of 1996 compared to
$2,018 thousand for the same period in 1995. The decreases reflect the impact of
the Company's $10 million investment in the variable funds of the separate
account, whose assets are invested predominantly in equity securities. The
dividend yield on the variable funds is significantly below the level of
interest earned on fixed income securities in which the $10 million was invested
prior to the fourth quarter of 1995.
    
 
FINANCIAL POSITION
 
At June 30, 1996, unrealized net capital gains before tax were $2.6 million
compared to $5.2 million at December 31, 1995. The change in unrealized gains in
the fixed income portfolio is due to the effect of rising interest rates.
 
At June 30, 1996 both contractholder funds and amounts recoverable from Allstate
Life under reinsurance treaties reflect a 27.8% increase of $372.7 million as
compared to December 31, 1995. These increases result from sales of the
Company's flexible premium fixed annuity contracts, partially offset by
surrenders. Reinsurance recoverable from Allstate Life relates to policy benefit
obligations ceded to Allstate Life.
 
   
Separate account assets increased by $83.5 million and separate account
liabilities increased by $82.9 million as compared to December 31, 1995. The
increases were primarily attributable to increased sales of flexible premium
deferred variable annuity contracts.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
Under the terms of intercompany reinsurance agreements, assets of the Company
that relate to insurance in force, excluding separate account assets, are
transferred to Allstate Life or other reinsurers, which maintain investment
portfolios that support the Company's products.
    
<PAGE>

COMPETITION
 
The Company is engaged in a business that is highly competitive because of the
large number of stock and mutual life insurance companies and other entities
competing in the sale of insurance and annuities. There are approximately 2,000
stock, mutual and other types of insurers in business in the United States.
Several independent rating agencies regularly evaluate life insurer's
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 the Company. A.M. Best Company also assigns the Company the
rating of A+(r) because the Company automatically reinsures all business with
Allstate Life. Standard & Poor's Insurance Rating Services assigns AA+
(Excellent) to Glenbrook Life's claims-paying ability and Moody's assigns an Aa3
(Excellent) financial stability rating to Glenbrook Life. These ratings do not
relate to the investment performance of the Variable Account.
 
EMPLOYEES
 
As of December 31, 1995, Allstate Life had approximately 43 employees at its
home office in Northbrook, Illinois who work primarily on the Company's matters.
 
PROPERTIES
 
The Company occupies office space provided by its parent, Allstate Life, in
Northbrook, Illinois. Expenses associated with these offices are allocated on a
direct and indirect basis to the Company.
 
STATE AND FEDERAL REGULATION
 
The insurance business of the Company is subject to comprehensive and detailed
regulation and supervision throughout the United States. The laws of the various
jurisdictions establish supervisory agencies with broad administrative powers
with respect to licensing to transact business, overseeing trade practices,
licensing agents, approving policy forms, establishing reserve requirements,
fixing maximum interest rates on life insurance policy loans and minimum rates
for accumulation of surrender values, prescribing the form and content of
required financial statements and regulating the type and amounts of investments
permitted. Each insurance company is required to file detailed annual reports
with supervisory agencies in each of the jurisdictions in which it does business
and its operations and accounts are subject to examination by such agencies at
regular intervals.
 
Under insurance guaranty fund law, in most states, insurers doing business
therein can be assessed up to prescribed limits for contract owner losses
incurred as a result of company insolvencies. The amount of any future
assessments on the Company under these laws cannot be reasonably estimated. Most
of these laws do provide, however, that an assessment may be excused or deferred
if it would threaten an insurer's own financial strength.
 
In addition, several states, including Illinois, regulate affiliated groups of
insurers, such as the Company and its affiliates, under insurance holding
company legislation. Under such laws, intercompany transfers of assets and
dividend payments from insurance subsidiaries may be subject to prior notice or
approval, depending on the size of such transfers and payments in relation to
the financial positions of the companies.
 
Although the federal government generally does not directly regulate the
business of insurance, federal initiatives often have an impact on the business
in a variety of ways. Current and proposed federal measures which may
significantly affect the insurance business include employee benefit regulation,
controls on medical care costs, removal of barriers preventing banks from
engaging in the securities and insurance business, tax law changes affecting the
taxation of insurance companies, the tax treatment of insurance products and its
impact on the relative desirability of various personal investment vehicles, and
proposed legislation to prohibit the use of gender in determining insurance and
pension rates and benefits.

LEGAL PROCEEDINGS
 
From time to time the Company is involved in pending and threatened litigation
in the normal course of its business in which claims for monetary damages are
asserted. Management, after consultation with legal counsel, does not anticipate
the ultimate liability arising from such pending or threatened litigation to
have a material effect on the financial condition of the Company.
 
EXPERTS
 
The financial statements of the Company as of December 31, 1995 and 1994 and for
each of the three years in the period ended December 31, 1995 and the related
financial statement schedule included in this prospectus have been audited by
Deloitte & Touche LLP, Two Prudential Plaza, 180 North Stetson Avenue, Chicago,
Illinois, 60601-6779 independent auditors, as stated in their report appearing
herein, and are included in reliance upon the report of such firm given upon

                          INDEPENDENT AUDITORS' REPORT
 
TO THE BOARD OF DIRECTORS AND SHAREHOLDER OF
GLENBROOK LIFE AND ANNUITY COMPANY:
 
We have audited the accompanying Statements of Financial Position of Glenbrook
Life and Annuity Company as of December 31, 1995 and 1994, and the related
Statements of Operations, Shareholder's Equity and Cash Flows for each of the
three years in the period ended December 31, 1995. Our audits also included
Schedule IV -- Reinsurance. These financial statements and financial statement
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these financial statements and financial statement
schedule based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, such financial statements present fairly, in all material
respects, the financial position of Glenbrook Life and Annuity Company as of
December 31, 1995 and 1994, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1995 in conformity
with generally accepted accounting principles. Also, in our opinion, Schedule IV
- -- Reinsurance, when considered in relation to the basic financial statements
taken as a whole, presents fairly, in all material respects, the information set
forth therein.
 
As discussed in Note 3 to the financial statements, in 1993 the Company changed
its method of accounting for investments in fixed income securities.

                       GLENBROOK LIFE AND ANNUITY COMPANY
                         NOTES TO FINANCIAL STATEMENTS
                                ($ in thousands)
 
1.  ORGANIZATION AND NATURE OF OPERATIONS
    Glenbrook Life and Annuity Company (the "Company") is wholly owned by
Allstate Life Insurance Company ("Allstate Life"), which is wholly owned by
Allstate Insurance Company ("Allstate"), a wholly-owned subsidiary of The
Allstate Corporation (the "Corporation"). On June 30, 1995, Sears, Roebuck and
Co. ("Sears") distributed its 80.3% ownership in the Corporation to Sears common
shareholders through a tax-free dividend (the "Distribution").
 
The Company develops and markets flexible premium deferred variable annuity
contracts and single and flexible premium deferred annuities to individuals
through banks and financial institutions in the United States.
 
Annuity contracts issued by the Company are subject to discretionary withdrawal
or surrender by the contractholder, subject to applicable surrender charges.
These contracts are reinsured with Allstate Life (Note 4) which selects assets
to meet the anticipated cash flow requirements of the assumed liabilities.
Allstate Life utilizes various modeling techniques in managing the relationship
between assets and liabilities and employs strategies to maintain investments
which are sufficiently liquid to meet obligations to contractholders in various
interest rate scenarios.
 
The Company monitors economic and regulatory developments which have the
potential to impact its business. Currently there is proposed legislation which
would permit banks greater participation in securities businesses, which could
eventually present an increased level of competition for sales of the Company's
annuity contracts. Furthermore, the federal government may enact changes which
could possibly eliminate the tax-advantaged nature of annuities or eliminate
consumers' need for tax deferral, thereby reducing the incentive for customers
to purchase the Company's products. While it is not possible to predict the
outcome of such issues with certainty, management evaluates the likelihood of
various outcomes and develops strategies, as appropriate, to respond to such
challenges.
 
Certain reclassifications have been made to the prior year financial statements
to conform to the presentation for the current year.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Life insurance accounting
 
The Company sells long-duration contracts that do not involve significant risk
of policyholder mortality or morbidity (principally single and flexible premium
annuities) which are considered investment contracts.
 
Contractholder funds
 
Contractholder funds arise from the issuance of individual and group annuities
that include an investment component. Payments received are recorded as
interest-bearing liabilities. Contractholder funds are equal to deposits
received and interest accrued to the benefit of the contractholder less
withdrawals, mortality charges and administrative expenses. Credited interest
rates on contractholder funds ranged from 3.0% to 7.4% for those contracts with
fixed interest rates and from 4.25% to 7.9% for those with flexible rates during
1995.
 
Separate Accounts
 
During 1995, the Company issued flexible premium deferred variable annuity
contracts, the assets and liabilities of which are legally segregated and
reflected in the accompanying statements of financial position as assets and
liabilities of the Separate Accounts (Glenbrook Life and Annuity Company
Variable Annuity Account and Glenbrook Life and Annuity Company Separate Account
A), unit investment trusts registered with the Securities and Exchange
Commission. Assets of the Separate Accounts are invested in funds of management
investment companies. For certain variable annuity contracts, the Company has
entered into an exclusive distribution arrangement with distributors.
 
The assets of the Separate Accounts are carried at fair value. Unrealized gains
and losses on the Company's participation in the Separate Account, net of
deferred income taxes, is shown as a component of shareholder's equity. The
Company's participation in the Separate Account, amounting to $10,530 at
December 31, 1995, is subject to certain withdrawal restrictions which are
dependent upon aggregate fund net asset values. In addition, limitations exist
with regard to the maximum amount which can be withdrawn by the Company within
any 30-day period.
 
Investment income and realized gains and losses of the Separate Accounts, other
than the portion related to the Company's participation, accrue directly to the
contractholders and, therefore, are not included in the accompanying statements
of operations. Revenues to the Company from the Separate Accounts consist of
contract maintenance fees, administrative fees and mortality and expense risk
charges, which are entirely ceded to Allstate Life.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)
Reinsurance
 
Beginning June 5, 1992, the Company reinsures all new business to Allstate Life
(Note 4). Life insurance in force prior to that date is ceded to non-affiliated
reinsurers.
 
Contract charges and credited interest are ceded and reflected net of such
cessions in the statements of operations. Reinsurance recoverable and
contractholder funds are reported separately in the statements of financial
position.
 
Investments
 
Fixed income securities include bonds and mortgage-backed securities. Fixed
income securities are carried at fair value. The difference between amortized
cost and fair value, net of deferred income taxes, is reflected as a separate
component of shareholder's equity. Provisions are made to write down the
carrying value of fixed income securities for declines in value that are other
than temporary. Such writedowns are included in realized capital gains and
losses.
 
Short-term investments are carried at cost which approximates fair value.
 
Investment income consists primarily of interest, which is recognized on an
accrual basis. Interest income on mortgage-backed securities is determined on
the effective yield method, based on the estimated principal repayments. Accrual
of income is suspended for fixed income securities that are in default or when
the receipt of interest payments is in doubt. Realized capital gains and losses
are determined on a specific identification basis.
 
Income taxes
 
The income tax provision is calculated under the liability method. Deferred tax
assets and liabilities are recorded based on the difference between the
financial statement and tax bases of assets and liabilities and the enacted tax
rates. Deferred income taxes also arise from unrealized capital gains or losses
on fixed income securities carried at fair value.
 
Use of estimates
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.
 
3.  ACCOUNTING CHANGE
 
Effective December 31, 1993, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." SFAS No. 115 requires that investments classified
as available for sale be carried at fair value. Previously, fixed income
securities classified as available for sale were carried at the lower of
amortized cost or fair value, determined in the aggregate. Unrealized holding
gains and losses are reflected as a separate component of shareholder's equity,
net of deferred income taxes. The net effect of adoption of this statement
increased shareholder's equity at December 31, 1993 by $693, with no impact on
net income.
 
4.  RELATED PARTY TRANSACTIONS
 
Reinsurance
 
Contract charges ceded to Allstate Life under reinsurance agreements were $1,523
and $409 in 1995 and 1994, respectively. Credited interest and expenses ceded to
Allstate Life amounted to $71,905 and $26,177 in 1995 and 1994, respectively.
Investment income earned on the assets which support contractholder funds is not
included in the Company's financial statements as those assets were transferred
to Allstate Life under the terms of reinsurance treaties. Reinsurance ceded
arrangements do not discharge the Company as the primary insurer.
 
Business operations
 
The Company utilizes services and business facilities owned or leased, and
operated by Allstate in conducting its business activities. The Company
reimburses Allstate for the operating expenses incurred by Allstate on behalf of
the Company. The cost to the Company is determined by various allocation methods
and is primarily related to the level of services provided. Operating expenses,

compensation and retirement and other benefit programs, allocated to the Company
were $348, $271 and $59 in 1995, 1994 and 1993, respectively. Investment-related
expenses are retained by the Company. All other costs are assumed by Allstate
Life under reinsurance treaties.
 
Laughlin Group
 
Laughlin Group, Inc. ("Laughlin"), a wholly-owned subsidiary of Laughlin Group
Holdings Inc., a wholly-owned subsidiary of Allstate Life which was acquired in
September 1995, is a third-party marketer which distributes the products of
insurance carriers including the Company. Laughlin markets the Company's
flexible premium deferred variable annuity contracts and flexible premium
deferred annuities. Sales commissions paid to Laughlin subsequent to the
acquisition date of $3,439 were ceded to Allstate Life.
 
5.  INCOME TAXES
 
Allstate Life and its life insurance subsidiaries, including the Company, will
file a consolidated federal income tax return. Tax liabilities and benefits
realized by the consolidated group are allocated as generated by the respective
subsidiaries, whether or not such benefits generated by the subsidiaries would
be available on a separate return basis. The Corporation and its domestic
subsidiaries including the Company (the "Allstate Group"), will be eligible to
file a consolidated tax return beginning in the year 2000.
 
Prior to the Distribution, the Allstate Group joined with Sears and its domestic
business units (the "Sears Group") in the filing of a consolidated federal
income tax return (the "Sears Tax Group") and were parties to a federal income
tax allocation agreement (the "Tax Sharing Agreement"). As a member of the Sears
Tax Group, the Corporation was jointly and severally liable for the consolidated
income tax liability of the Sears Tax Group. Under the Tax Sharing Agreement,
the Company, through the Corporation, paid to or received from the Sears Group
the amount, if any, by which the Sears Tax Group's federal income tax liability
was affected by virtue of inclusion of the Allstate Group in the consolidated
federal income tax return. Effectively, this resulted in the Company's annual
income tax provision being computed as if the Company filed a separate return,
except that items such as net operating losses, capital losses or similar items
which might not be immediately recognizable in a separate return, were allocated
according to the Tax Sharing Agreement and reflected in the Company's provision
to the extent that such items reduced the Sears Tax Group's federal tax
liability.
 
The Allstate Group and Sears Group have entered into an agreement which governs
their respective rights and obligations with respect to federal income taxes for
all periods prior to the Distribution ("Consolidated Tax Years"). The agreement
provides that all Consolidated Tax Years will continue to be governed by the Tax
Sharing Agreement with respect to the Company's federal income tax liability and
taxes payable to or recoverable from the Sears Group.
 
The components of the deferred income tax assets and liabilities at December 31,
1995 and 1994 are as follows:

6.  INVESTMENTS (Continued)
Proceeds from sales of fixed income securities
 
The proceeds from sales of investments in fixed income securities, excluding
calls, were $7,836 and $3,015, with related gross realized gains of $459 and $22
for 1995 and 1993, respectively. There were no such amounts realized in 1994.
 
Securities on deposit
 
At December 31, 1995, fixed income securities with a carrying value of $10,085
were on deposit with regulatory authorities as required by law.
 
7.  FINANCIAL INSTRUMENTS
    In the normal course of business, the Company invests in various financial
assets and incurs various financial liabilities. The fair value of all financial
assets other than fixed income securities and all liabilities other than
contractholder funds approximates their carrying value as they are short-term in
nature.
 
Fair values for fixed income securities are based on quoted market prices. The
December 31, 1995 and 1994 fair values and carrying values of fixed income
securities are discussed in Note 6.
 
The fair value of contractholder funds on investment contracts is based on the
terms of the underlying contracts. Reserves on investment contracts with no
stated maturities (single premium and flexible premium deferred annuities) are
valued at the fund balance less surrender charge. The fair value of immediate
annuities with fixed terms are estimated using discounted cash flow calculations
based on interest rates currently offered for contracts with similar terms and
duration. Contractholder funds on investment contracts had a carrying value of
$1,340,925 at December 31, 1995 and a fair value of $1,282,248. The carrying
value and fair value at December 31, 1994 were $696,854 and $670,930,
respectively.

of shareholder dividends by insurance companies without the prior approval of
the state insurance regulator is limited to formula amounts based on net income
and capital and surplus, determined in accordance with statutory accounting
practices, as well as the timing and amount of dividends paid in the preceding
twelve months. The maximum amount of dividends that the Company can distribute
during 1996 without prior approval of both the Illinois and California
Departments of Insurance is $5,220.

                         NOTES TO FINANCIAL STATEMENTS
                                  (Unaudited)
                                ($ in thousands)
 
1.  BASIS OF PRESENTATION
 
Glenbrook Life and Annuity Company (the "Company") is wholly owned by Allstate
Life Insurance Company ("Allstate Life"), which is wholly owned by Allstate
Insurance Company, a wholly-owned subsidiary of The Allstate Corporation.
 
The statements of financial position as of June 30, 1996, the statements of
operations for the three-month and six-month periods ended June 30, 1996 and
1995, and the statements of cash flows for the six-month periods then ended are
unaudited. These interim financial statements reflect all adjustments
(consisting only of normal recurring accruals) which are, in the opinion of
management, necessary for the fair presentation of the financial position,
results of operations and cash flows for the interim periods. The financial
statements should be read in conjunction with the financial statements and notes
thereto included in the Glenbrook Life and Annuity Company Annual Report on Form
10K for 1995. The results of operations for the interim periods should not be
considered indicative of results to be expected for the full year.
 
To conform with the 1996 presentation, certain items in the prior year's
financial statements have been reclassified.
 
2.  REINSURANCE
 
The Company reinsures substantially all business with Allstate Life. Contract
charges ceded to Allstate Life under reinsurance agreements were $1,480 and $806
for the six-month periods ended June 30, 1996 and 1995, respectively. Credited
interest and expenses ceded to Allstate Life amounted to $52,768 and $29,890 for
the six-month periods ended June 30, 1996 and 1995, respectively. Investment
income earned on the assets which support contractholder funds was excluded from
the Company's financial statements as those assets were transferred to Allstate
Life under the terms of reinsurance treaties. Reinsurance ceded arrangements do
not discharge the Company as the primary insurer.

                            MARKET VALUE ADJUSTMENT
 
The Market Value Adjustment is based on the following:
 
<TABLE>
<C>        <S>
      I =  the Treasury Rate for a maturity equal to the Sub-account's Guarantee Period for the
           week preceding the establishment of the Sub-account.
 
      N =  the number of whole and partial years from the date we receive the withdrawal,
           transfer, or death benefit request, or from the Payout Start Date to the end of the
           Sub-account's Guarantee Period.
 
      J =  the Treasury Rate for a maturity equal to the Sub-accounts Guarantee Periodfor the week
           preceding the receipt of the withdrawal request, transfer request, death benefit
           request, or income payment request. If a Note with a maturity of the original guarantee
           period is not available, a weighted average will be used.
</TABLE>
 
Treasury Rate means the U.S. Treasury Note Constant Maturity yield as reported
in Federal Reserve Bulletin Release H.15.
 
The Market Value Adjustment factor is determined from the following formula:
 
 .9* (I-J)* N
 
Any transfer, withdrawal in excess of the free withdrawal amount, or death
benefit paid from a Sub-account of the Guaranteed Maturity Fixed Account will be
multiplied by the Market Value Adjustment factor to determine the Market Value
Adjustment.

    NOTE: This illustration assumes that premium taxes were not applicable.
 
                 Example 1: (Assumes declining interest rates)
 
           Step 1: Calculate Account Value at End of Contract Year 3:
 
                      = 10,000.00 * (1.475)3 = $11,493.76
 
                 Step 2: Calculate the Free Withdrawal Amount:
 
                        = .15 * (10,000.00) = $1,500.00
 
                    Step 3: Calculate the Withdrawal Charge:
 
                    = .05 * (10,000.00 - 1,500.00) = $425.00
 
                 Step 4: Calculate the Market Value Adjustment:
 
                                    I= 4.75%
                                    J= 4.25%
                                    N =730 days = 2
          365 days
 
                Market Value Adjustment Factor: .9 * (I--J) * N
 
                                      A-1
<PAGE>
                       = .9 * (.0475 - .0425) * 2 = .009
 
 Market Value Adjustment = Factor * Amount Subject to Market Value Adjustment:
 
                      = .009 * (11,493.76 - 1,500) $89.94
 
    Step 5: Calculate The Amount Received by Customers as a Result of a Full
                   Withdrawal at the end of Contract Year 3:
 
                   = 11,493.76 - 425.00 + 89.94 = $11,158.70
 
                   Example 2: (Assumes rising interest rates)
 
           Step 1: Calculate Account Value at End of Contract Year 3:
 
                      = 10,000.00 * (1.0475)3 = $11,493.76
 
                 Step 2: Calculate the Free Withdrawal Amount:
 
                        = .15 * (10,000.00) = $1,500.00
 
                    Step 3: Calculate the Withdrawal Charge:
 
                    = .05 * (10,000.00 - 1,500.00) = $425.00
 
                 Step 4: Calculate the Market Value Adjustment:
 
                                    I= 4.75%
                                    J= 5.25%
                                    N =730 days = 2
          365 days
 
                 Market Value Adjustment Factor: .9 * (I-J) * N
 
                      = .9 * (.0475 - .0525) * (2) = -.009
 
  Market Value Adjustment = Factor * Amount Subject to Market Value Adjustment
 
                     = -.009 * ($11,493.76 -1,500) = 89.94
 
     Step 5: Calculate The Net Withdrawal Value at End of Contract Year 3:
 
                   = 11,493.76 - 425.00 - 89.94 = $10,978.82

ITEM 17. UNDERTAKINGS
 
    The undersigned registrant, Glenbrook Life and Annuity Company, hereby
undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
       post-effective amendment to this 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;
 
       (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; and
 
    (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 ("Act") may be permitted to directors, officers and controlling persons
of Glenbrook Life and Annuity Company ("Registrant"), 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 that the payment by Registrant of expenses incurred or
paid by a director, officer or controlling person of 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, 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 Act and will be governed by the final adjudication of
such issue.

RE:      FORM S-1 REGISTRATION STATEMENT
         UNDER THE SECURITIES ACT  OF  1933
         FILE NO. 333-00987

    With reference to the Registration Statement on Form S-1 filed by Glenbrook
Life and Annuity Company with the Securities and Exchange Commission covering
the Flexible Premium Deferred Variable Annuity Contracts ("Contracts"), I have
examined such documents and such law as I have considered necessary and
appropriate, and on the basis of such examination, it is my opinion that:

   1.    Glenbrook Life and Annuity Company is duly organized and existing
         under the laws of the State of Illinois and has been duly authorized
         to do business and to issue the Contracts by the Director of Insurance
         of the State of Illinois.

   2.    The Contracts covered by the above Registration Statement have been or
         will be approved and authorized by the Director of Insurance of the
         State of Illinois and when issued will be valid, legal and binding
         obligations of Glenbrook Life and Annuity Company.

    I hereby consent to the filing of this opinion as an exhibit to the above
referenced Registration Statement and to the use of my name under the caption
"Legal Matters" in the Prospectus constituting a part of the Registration
Statement.

                             Sincerely,


                             /s/MICHAEL J. VELOTTA
