PROSPECTUS
MAY 1, 1996.


    This  prospectus  describes the  AIM Lifetime  Plus-SM- Variable  Annuity, a
Flexible Premium Deferred Variable Annuity Contract ("Contract") designed to aid
you in  long-term  financial planning  and  which  can be  used  for  retirement
planning.  The  Contracts  are  issued by  Glenbrook  Life  and  Annuity Company
("Company"), a  wholly  owned subsidiary  of  Allstate Life  Insurance  Company.
Purchase  payments for the Contracts  will be allocated to  a series of Variable
Sub-accounts of  the  Glenbrook Life  and  Annuity Company  Separate  Account  A
("Variable  Account") and/or  to a  Fixed Account  option(s) funded  through the
Company's general account.

 

    The Contracts are issued as individual  Contracts or as group Contracts.  In
states  where the Contracts are available only as group Contracts, a certificate
is issued that summarizes the provisions of the group Contract. For convenience,
this prospectus refers to both Contracts and certificates as "Contracts."

 
    The Variable Sub-accounts invest in shares of AIM Variable Insurance  Funds,
Inc.  (the "Fund  Series"). Nine  Funds are  currently available  for investment
within the Variable  Account: (1) AIM  V.I. Capital Appreciation  Fund; (2)  AIM
V.I.  Diversified Income Fund; (3) AIM V.I.  Global Utilities Fund; (4) AIM V.I.
Government Securities Fund; (5)  AIM V.I. Growth Fund;  (6) AIM V.I. Growth  and
Income  Fund; (7) AIM V.I. International Equity  Fund; (8) AIM V.I. Money Market
Fund; and (9) AIM V.I. Value Fund.
 
    This prospectus  presents  information  you  should  know  before  making  a
decision to invest in the Contract and the available Investment Alternatives.
 

    The  Contract  Value  will  vary  daily  as  a  function  of  the investment
performance of  the  Sub-accounts  of  our Variable  Account  and  any  interest
credited  to  the Fixed  Account.  The Company  does  not guarantee  any minimum
Contract Value for amounts allocated to the Variable Account. Benefits  provided
by this Contract, when based on the Fixed Account, are subject to a Market Value
Adjustment,  the operation of which may result in upward or downward adjustments
in withdrawal benefits,  death benefits, settlement  values, transfers to  other
Sub-accounts, or periodic income payments.

 

    THE   CONTRACTS  MAY  BE  DISTRIBUTED   THROUGH  BROKER-DEALERS  WHICH  HAVE
RELATIONSHIPS WITH BANKS OR OTHER FINANCIAL INSTITUTIONS OR BY EMPLOYEES OF SUCH
BANKS; HOWEVER, THE CONTRACTS AND THE INVESTMENTS IN THE FUNDS ARE NOT DEPOSITS,
OR OBLIGATIONS OF, OR GUARANTEED OR ENDORSED BY ANY BANK, AND THE FUNDS'  SHARES
ARE  NOT FEDERALLY  INSURED OR  GUARANTEED BY  THE U.S.  GOVERNMENT, THE FEDERAL
DEPOSIT INSURANCE CORPORATION, THE  FEDERAL RESERVE BOARD  OR ANY OTHER  AGENCY.
INVESTMENT  IN THE CONTRACTS  INVOLVES INVESTMENT RISKS,  INCLUDING THE POSSIBLE
LOSS OF PRINCIPAL.

 

    The Company has  prepared and  filed a Statement  of Additional  Information
dated  May 1, 1996 with the U.S. Securities and Exchange Commission. If you wish
to receive the Statement of Additional  Information, you may obtain a free  copy

    ANNUITANT(S):  The person or persons whose life determines the latest Payout
Start  Date and the amount  and duration of any  income payments for Income Plan

the Variable Account and/or may be fixed for the duration of the Income Plan.
 
    INVESTMENT ALTERNATIVES:  The Sub-accounts  of the Variable Account and  the
Fixed Account.
 
    MARKET VALUE ADJUSTMENT:  The Market Value Adjustment is the adjustment made

THE CONTRACT
 

    This  Contract is designed  for long-term financial  planning and retirement
planning. Money can be  allocated to any combination  of Funds and/or the  Fixed
Account.  You have access  to your funds either  through withdrawals of Contract
Value or through periodic income payments.  You bear the entire investment  risk
for Contract Values and income payments based upon the Variable Account, because
values  will vary  depending on  the investment  performance of  the Fund(s) you
select. See "Accumulation Unit Value," page 12 and "Income Plans," page 14.  You
will  also bear the investment risk of  adverse changes in interest rates in the
event amounts are prematurely withdrawn or transferred from Sub-accounts of  the
Fixed Account. See "Fixed Account," page 10.

 
FREE-LOOK
 

    You  may cancel the  Contract any time  within 20 days  after receipt of the
Contract and receive a full refund  of purchase payments allocated to the  Fixed
Account.  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. See "Free-Look Period," page 12.

 
HOW TO INVEST
 

    Your  first  purchase  payment  must  be  at  least  $5,000  (for  Qualified
Contracts, $2,000). Subsequent purchase payments must be at least $500. Purchase
payments may  also  be made  pursuant  to  an Automatic  Addition  Program.  See
"Purchase  Payment Limits," page 10.  At the time of  your application, you will
allocate your purchase payment among the Investment Alternatives. The allocation
you specify on the  application will be  effective immediately. All  allocations
must  be in whole percents from 0% to  100% (total allocation equals 100%) or in
whole  dollars  (total  allocation  equals  entire  dollar  amount  of  purchase
payment).  Allocations may be  changed by notifying the  Company in writing. See
"Allocation of Purchase Payments," page 12.

 
INVESTMENT ALTERNATIVES
 

    The Variable Account invests in shares of AIM Variable Insurance Funds, Inc.
(the "Fund Series"). The Fund Series has  a total of nine Funds available  under
the Contract. The Funds include: (1) AIM V.I. Capital Appreciation Fund; (2) AIM
V.I.  Diversified Income Fund; (3) AIM V.I.  Global Utilities Fund; (4) AIM V.I.
Government Securities Fund; (5)  AIM V.I. Growth Fund;  (6) AIM V.I. Growth  and
Income  Fund; (7) AIM V.I. International Equity  Fund; (8) AIM V.I. Money Market
Fund; and (9) AIM V.I. Value Fund.  The assets of each Fund are held  separately
from  the other Funds  and each has distinct  investment objectives and policies
which are  described in  the accompanying  prospectus for  the Fund  Series.  In
addition  to the Variable Account, Owners can also allocate all or part of their
purchase payments to the Fixed Account. See "Fixed Account," on page 10.

 
TRANSFERS AMONG INVESTMENT ALTERNATIVES
 

    Prior to  the  Payout  Start  Date,  you  may  transfer  amounts  among  the
Investment  Alternatives. 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 the  Fixed Account  must be  at least  $500.
Certain  Fixed  Account  transfers  may  be  restricted.  See  "Transfers  Among
Investment Alternatives,"  page 11.  You may  want to  enroll in  a Dollar  Cost
Averaging  Program or  an Automatic Fund  Rebalancing Program.  See "Dollar Cost
Averaging," page 12, and "Automatic Fund Rebalancing," page 13.

 
CHARGES AND DEDUCTIONS
 

    The costs  of  the Contract  include:  a contract  maintenance  charge  ($35
annually),  a mortality  and expense  risk charge  (deducted daily,  equal on an
annual basis  to  1.35% of  the  Contract's daily  net  assets of  the  Variable
Account),  and an  administrative expense  charge (deducted  daily, equal  on an
annual basis  to  .10%  of the  Contract's  daily  net assets  of  the  Variable
Account).  The Company reserves  the right to  assess a transfer  charge ($10 on
each transfer in excess of twelve per Contract Year). Additional deductions  may
be  made  for  certain  taxes.  See  "Contract  Maintenance  Charge,"  page  17,
"Mortality and Expense Risk Charge,"  page 17, "Administrative Expense  Charge,"
page 17, "Transfer Charges," page 17, and "Taxes," page 17.

 
WITHDRAWALS
 

    You  may withdraw all or  part of the Contract  Value 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. Each Contract Year, no withdrawal charges or
Market  Value Adjustments will be applied to  amounts withdrawn up to 10% of the
amount of  purchase payments.  Amounts withdrawn  in excess  of the  10% may  be
subject  to  a withdrawal  charge of  0% to  6% depending  on how  long purchase
payments  have  been  invested  in  the  Contract.  Amounts  withdrawn  from   a
Sub-account of the Fixed Account, in excess of the 10%, except during the 30 day
period  after the Guarantee  Period expires, will  be subject to  a Market Value
Adjustment. See "Withdrawals," page 13, "Withdrawals or Transfers," page 11, and
"Taxation of Annuities in General," page 19.

INCOME PAYMENTS

Date.  You  may choose  among several  Income  Plans to  fit your  needs. Income

    All Sub-Accounts commenced operations on December 4, 1995. The  Accumulation
Unit  Values in this table reflect a  Mortality and Expense Risk Charge of 1.35%
and an Administrative Expense Charge of 0.10%.

 
                       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  usually
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.
 
                                       7
    
<PAGE>
   
    In  addition to the standardized total return, the Sub-account may advertise
a non-standardized total return. This figure will usually 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 AIM V.I. 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  AIM V.I.  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 AIM
V.I. 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 Funds and the  assumption
that  the Sub-accounts were  in existence for  the same periods  as those of the
underlying Funds, 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.

          GLENBROOK LIFE AND ANNUITY COMPANY AND THE VARIABLE ACCOUNT
 
GLENBROOK LIFE AND ANNUITY COMPANY
 

    The  Company is  the issuer  of the  Contract. The  Company is  a stock life
insurance company which was organized under the laws of the State of Illinois in
1992. The  Company was  originally organized  under  the laws  of the  State  of
Indiana  in 1965. From  1965 to 1983  the Company was  known as "United Standard
Life Assurance Company" and from 1983 to 1992 the Company was known as  "William
Penn  Life Assurance Company of America." As of the date of this prospectus, the
Company is licensed to operate in the District of Columbia and all states except
New York. The Company intends to  market the Contract in those jurisdictions  in
which  it is licensed to  operate. The Company's home  office is located at 3100
Sanders Road, Northbrook, Illinois 60062.

 

    The Company is a wholly-owned subsidiary of Allstate Life Insurance  Company
("Allstate Life"), a stock life insurance company incorporated under the laws of
the  State of Illinois.  Allstate Life is a  wholly-owned subsidiary of Allstate
Insurance Company  ("Allstate"), a  stock property-liability  insurance  company
incorporated under the laws of Illinois. All of the outstanding capital stock of
Allstate  is owned  by The Allstate  Corporation ("Corporation").  In June 1995,
Sears, Roebuck and Co.  distributed in a tax-free  dividend to its  stockholders
its remaining 80.3% ownership in the Corporation.

 

    The  Company  and  Allstate  Life  entered  into  a  reinsurance  agreement,
effective June 5, 1992. Under the reinsurance agreement, Fixed Account  purchase
payments are automatically transferred to Allstate Life and become invested with
the  assets of Allstate  Life, and Allstate  Life accepts 100%  of the liability
under such  contracts.  However, the  obligations  of Allstate  Life  under  the
reinsurance  agreement are to the Company;  the Company remains the sole obligor
under the Contract to the Owners.

 
THE VARIABLE ACCOUNT
 

    Established on September  6, 1995,  the Glenbrook Life  and Annuity  Company
Separate Account A 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 nine Sub-accounts, each of  which
invests  solely in its corresponding Fund  of AIM Variable Insurance Funds, Inc.
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 FUND SERIES
 
    The  Variable Account  will invest in  shares of the  AIM Variable Insurance
Funds, Inc.  (the  "Fund  Series").  The Fund  Series  is  registered  with  the
Securities and Exchange Commission as an open-end, series, management investment
company.  Registration of  the Fund Series  does not involve  supervision of its
management, investment  practices or  policies by  the Securities  and  Exchange
Commission.  The Funds are designed to  provide investment vehicles for variable
insurance contracts of various insurance companies, in addition to the  Variable
Account.
 
    Shares  of the Funds are  not deposits, or obligations  of, or guaranteed or
endorsed by any bank  and the shares  are not federally  insured by the  Federal
Deposit Insurance Corporation, the Federal Reserve Board or any other agency.

the investment objectives and programs of the Funds:
 
    AIM  V.I.  CAPITAL  APPRECIATION  FUND ("CAPITAL  APPRECIATION  FUND")  is a
diversified Fund which seeks to provide capital appreciation through investments
in common  stocks, with  emphasis on  medium-sized and  smaller emerging  growth
companies.
 

    AIM   V.I.  DIVERSIFIED  INCOME  FUND   ("DIVERSIFIED  INCOME  FUND")  is  a
diversified Fund which seeks to achieve a high level of current income primarily
by investing  in a  diversified portfolio  of foreign  and U.S.  government  and

(commonly known  as "junk  bonds"). The  risks of  investing in  junk bonds  are
described  in the accompanying  prospectus for the Fund  Series, which should be
read carefully before investing.

 
    AIM  V.I.   GLOBAL   UTILITIES  FUND   ("GLOBAL   UTILITIES  FUND")   is   a
non-diversified  Fund which seeks to achieve a high level of current income and,
as  a  secondary  objective,  to  achieve  capital  appreciation,  by  investing
primarily  in common  and preferred stocks  of public  utility companies (either
domestic or foreign).
 
    AIM V.I. GOVERNMENT  SECURITIES FUND  ("GOVERNMENT FUND")  is a  diversified
Fund  which seeks  to achieve  a high  level of  current income  consistent with
reasonable concern  for safety  of  principal by  investing in  debt  securities
issued, guaranteed or otherwise backed by the U.S. Government.
 
    AIM  V.I. GROWTH FUND ("GROWTH  FUND") is a diversified  Fund which seeks to
provide growth  of capital  through investments  primarily in  common stocks  of

which have prospects for both growth of capital and dividend income.
 
    AIM V.I. INTERNATIONAL EQUITY FUND  ("INTERNATIONAL FUND") is a  diversified
Fund  which  seeks  to  provide  long-term growth  of  capital  by  investing in
international equity securities, the issuers of  which are considered by AIM  to
have strong earnings momentum.
 
    AIM V.I. MONEY MARKET FUND ("MONEY MARKET FUND") is a diversified Fund which
seeks  to provide as  high a level of  current income as  is consistent with the
preservation of capital and liquidity by investing in a diversified portfolio of
money market instruments.
 
    AIM V.I. VALUE  FUND ("VALUE  FUND") is a  diversified Fund  which seeks  to
achieve  long-term growth of capital by investing primarily in equity securities

markets generally. Income is a secondary objective.

accompanying this prospectus.
 
    You will find more complete information about the Funds, including the risks
associated  with each Fund, in the  accompanying prospectus. You should read the
prospectus for the Fund Series in conjunction with this prospectus.
 
    THE FUND SERIES PROSPECTUS SHOULD BE  READ CAREFULLY BEFORE ANY DECISION  IS
MADE  CONCERNING THE  ALLOCATION OF PURCHASE  PAYMENTS TO  A PARTICULAR VARIABLE
SUB-ACCOUNT.
 
                                 FIXED ACCOUNT
 
    Purchase payments and transfers allocated to one or more of the Sub-accounts
of the 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) in  which to allocate each
purchase payment and transfer.  No less than  $500 may be  allocated to any  one
Sub-account.  The Company reserves  the right to limit  the number of additional
purchase payments. The Fixed Account Investment Alternative 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.
 
    The   following  example  illustrates  how   the  Sub-account  value  for  a
Sub-account of the Fixed Account would  grow given an assumed purchase  payment,
Guarantee Period, and effective annual interest rate:

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  10% 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. The Company guarantees that the interest rates
will never be less than the minimum  guaranteed rate shown in the Contract.  For
current  interest rate information, please  contact your sales representative or
the Company's Customer Support Unit at 1(800)776-6978.

 
    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.
 
    Prior to 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 on  the
      day the previous Guaranteed Period expired; or
 
    - notify  the  Company to  apply the  Sub-account value  to a  new Guarantee
      Period or periods  to be  established on  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
 
    - 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
      withdrawn on the day 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)776-6978.
 
WITHDRAWALS OR TRANSFERS
 
    With  the  exception of  transfers  made automatically  through  dollar cost
averaging, all withdrawals and transfers, paid  from a Sub-account of the  Fixed
Account other than during the 30 day period after a Guarantee Period expires are
subject to a Market Value Adjustment.
 
    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).
 
MARKET VALUE ADJUSTMENT
 
    The Market  Value  Adjustment  reflects the  relationship  between  (1)  the
Treasury  Rate for the time remaining in the Guarantee Period at the time of the
request for withdrawal or transfer,  and (2) the Treasury  Rate 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 for the Guarantee Period 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 Treasury Rate (interest rate for a period equal to the time remaining
in  the Sub-account), 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 two 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 two 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 $5,000 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 $500 or more and may be made at
any  time prior to the Payout Start  Date. Subsequent purchase payments may also
be made from your bank account  through Automatic Additions. Under an  Automatic
Additions  Program, the minimum purchase payment  for allocation to the Variable
Account is $100  and for allocation  to the Fixed  Account the minimum  purchase
payment  is $500.  Please consult  with your  sales representative  for detailed
information about Automatic Additions.
 
    We reserve  the right  to limit  the  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 and receive a full refund  of purchase payments allocated to the  Fixed
Account.  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 to any
Investment Alternative  in whole  percents, from  0% to  100% (total  allocation
equals  100%) or in whole dollars  (total allocation equals entire dollar amount
of purchase payments).  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 Fund.
 
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. See "Withdrawals or  Transfers," page 10 for the requirements
on transfers from  the Fixed  Account. After  the Payout  Start Date,  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,  transfers from a fixed  amount income payment are
not allowed.

 
    Telephone transfer requests will be accepted  by the Company if received  at
1(800)776-6978  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
 
                                       12
    
<PAGE>
   
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 Fixed
Account is $500. Any transfer from a Sub-account of the Fixed Account at a  time
other  than during the  30 day period  after a Guarantee  Period expires will be
subject to a Market  Value Adjustment. If  any transfer reduces  the value of  a
Sub-account  of the Fixed Account to less  than $500, the Company will treat the
request as a transfer of the entire Sub-account value.
 
    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  one year Guarantee Period Sub-account  of
the Fixed Account or any of the Variable Sub-accounts, to any Sub-account of the
Variable  Account. Dollar Cost  Averaging cannot be used  to transfer amounts to
the Fixed Account. Transfers made through Dollar Cost Averaging are not  subject
to a Market Value Adjustment. 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 FUND REBALANCING
 
    Transfers may be made automatically through Automatic Fund Rebalancing prior
to the Payout  Start Date. By  electing Automatic Fund  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 Fund 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 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 withdrawal  charges, contract maintenance  charges and any
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 18.

 

    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 Alternatives 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 any withdrawal reduces the value
of any Sub-account of  the Fixed Account  to less than $500,  we will treat  the
request  as a withdrawal of the entire  Sub-account value. If the Contract Value
after a partial  withdrawal would  be less than  $1,000, 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 Fund Rebalancing.
 
                                       13
    
<PAGE>
   

    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
19.

 

    After the Payout Start  Date, withdrawals are  only permitted when  payments
from the Variable Account are being made for a specified number of payments only
(i.e.  Income Plan  3). 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.

 
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 Funds, 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 Sub-accounts  of
the  Fixed Account during the  accumulation phase are fixed  for the duration of
the Income  Plan.  The fixed  amount  income  payment amount  is  calculated  by
applying  the portion of the  Contract Value in the  Fixed Account 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.
 
                                       14
    
<PAGE>
   
    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.
 
    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 an Income Plan is selected or a surviving  spouse
continues the Contract 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  death benefit is equal to the greatest
of:
 
    (a)  the Contract  Value  on  the  date the  Company  determines  the  death
         benefit; or
 
    (b)  the  amount  that  would have  been  payable  in the  event  of  a full
         withdrawal of the Contract Value on the date the Company determines the
         death benefit; or
 
    (c)  the  Contract  Value  on  the  Death  Benefit  Anniversary  immediately
         preceding 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.
 
                                       15
    
<PAGE>
   
    In  addition to the above options, upon  purchase of the Contract, the Owner
can select one of the following enhanced death benefit options:
 
    (A)  the greatest of the anniversary values as of the date we determine  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 the amount of 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 deceased's attained age  75 or 5 years
         after the date the Contract was established, if later; or
 
    (B)  total purchase payments minus the sum of all partial withdrawals.  Each
         purchase  payment and each partial  withdrawal will accumulate daily at
         rate equivalent to 5% per  year until the earlier  of: (i) the date  we
         determine  the  death  benefit, or  (ii)  the  first day  of  the month
         following the deceased's 75th birthday or 5 years after the issue date,
         if later.
 
    If neither option is selected by the Owner, the Contract will  automatically
include option (A).
 
    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 10% 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.
 

    Free  withdrawals and other partial withdrawals will be allocated on a first
in, first out basis to purchase payments. 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 received 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:

    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 19.

 
    The Company reserves the right to  waive the withdrawal charge with  respect
to   Contracts  issued  to  employees  and  registered  representatives  of  any
broker-dealer that  has  entered  into  a sales  agreement  with  Allstate  Life
Financial  Services, Inc. ("ALFS") to sell the Contracts and all wholesalers and
their employees that are under agreement with ALFS to wholesale the Contract. In
addition, the Company
 
                                       16
    
<PAGE>
   
will waive any withdrawal charge prior to  the Payout Start Date if 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 90  days after discharge.  The
withdrawal  charge  will also  be  waived on  withdrawals  taken to  satisfy IRS
required minimum distribution rules for this Contract.
 
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. 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.
 
    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 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  full  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  you have  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 1.35% of the  daily net assets you have allocated to  the
Sub-accounts  of  the  Variable  Account. The  Company  estimates  that  .95% is
attributable to the assumption  of mortality risks and  .40% is attributable  to
the  assumption of expense risks. The Company guarantees that the amount of 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 Fund Rebalancing. The Company is presently waiving this
charge.

                                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 Annuitant 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, 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.
 
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

                              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 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 Funds  or their  investments, the  Company  expects the  Funds 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
 
                                       19
    
<PAGE>
   
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 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.
 
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
 
                                       20
    
<PAGE>
   
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 Insurance
Company, 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
6.75% 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 1.20%,  on  an  annual  basis,  of  the  Contract  Values  considered  in
connection  with the bonus. These commissions are intended to cover distribution
expenses.
 
    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 Series. The Company will solicit and cast each vote according to the
procedures set up  by the Fund  Series 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 Fund.)
 
    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 Fund.
 
                            SELECTED FINANCIAL DATA

                      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.

</TABLE>

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

(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.

 
                                       22
    
<PAGE>
   

    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.

 
                                  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 the Company's  claims-paying ability and  Moody's assigns an Aa3
(Excellent) financial stability rating  to the Company.  The Company shares  the
same  ratings of its  parent, Allstate Life Insurance  Company. These ratings do
not relate to the investment performance of the Variable Account.

 
                                   EMPLOYEES
 

    As  of  December  31,   1995,  Glenbrook  Life   and  Annuity  Company   had
approximately 43 employees at its Home Office in Northbrook, Illinois.

 
                                   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.

                          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.

                         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,
including  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.

4.  RELATED PARTY TRANSACTIONS (CONTINUED)


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:

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

PERMITTED STATUTORY ACCOUNTING PRACTICES

 

    The Company prepares their statutory financial statements in accordance with
accounting principles and  practices prescribed  or permitted  by the  insurance
department  of the State of  Illinois. Prescribed statutory accounting practices
include a  variety of  publications  of the  National Association  of  Insurance
Commissioners,  as well as  state laws, regulations,  and general administrative
rules.  Permitted  statutory  accounting  practices  encompass  all   accounting
practices not so prescribed. The Company does not follow any permitted statutory
accounting  practices  that  have  a material  effect  on  statutory  surplus or
risk-based capital.

 

DIVIDENDS

 

    The ability  of  the Company  to  pay  dividends is  dependent  on  business
conditions, income, cash requirements of the Company and other relevant factors.
The  payment 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.

N          =          the number of  whole and partial  years from the  date we receive  the withdrawal,  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 of length N for the week preceding the receipt of the
                      withdrawal request, death benefit request, or income payment request. If a Note with a
                      maturity of length N is not  available, a weighted average will  be used. If N is  one
                      year or less, J will be the 1-year Treasury Rate.
</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 X (I-J) X N
 
    Any transfer, withdrawal in excess of  the free withdrawal amount, or  death
benefit  paid from a Sub-account of the  Fixed Account will be multiplied by the
Market Value Adjustment factor to determine the Market Value Adjustment.

EXAMPLE OF MARKET VALUE ADJUSTMENT
 
<TABLE>
    <S>                <C>
    Purchase Payment:  $10,000
    Guarantee Period:  5 Years
    Interest Rate:     4.75%
    Full Withdrawal:   End of Contract Year 3
</TABLE>
 
   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 X (1.0475)3 = $11,493.76
 
Step 2:  Calculate the Free Withdrawal Amount:
 
                    = 10% X (10,000.00) = $1,000.00
 
Step 3:  Calculate the Withdrawal Charge:
 
                    = .05 X (10,000.00 - 1,000.00) = $450.00
 
Step 4:  Calculate the Market Value Adjustment:
         I = 4.75%
         J = 4.25%
         N = 730 DAYS = 2
         ----------

<PAGE>
   
 
Market Value Adjustment Factor: .9 X (I-J) X N
 
         = .9 X (.0475 - .0425) X 2 = .009
 
Market Value Adjustment = Factor X Amount Subject to Market Value Adjustment:
 
         = .009 X (11,493.76 - 1,000) = $94.44
 
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 - 450.00 + 94.44 = $11,138.20
 
EXAMPLE 2: (ASSUMES RISING INTEREST RATES)
 
Step 1:  Calculate Account Value at End of Contract Year 3:
 
         = 10,000.00 X (1.0475)3 = $11,493.76
 
Step 2:  Calculate the Free Withdrawal Amount
 
         = 10% X (10,000.00) = $1,000.00
 
Step 3:  Calculate the Withdrawal Charge:
 
         = .05 X (10,000.00 - 1,000.00) = $450.00
 
Step 4:  Calculate the Market Value Adjustment:
         I = 4.75%
         J = 5.25%
         N = 730 DAYS = 2
         ----------
         365 days
 
Market Value Adjustment Factor: .9 X (I-J) X N
 
         = .9 X (.0475 - .0525) X (2) = -.009
 
Market Value Adjustment = Factor X Amount Subject to Market Value Adjustment:
 
         = -.009 X ($11,493.76 - 1,000) = -94.44
 
Step 5:  Calculate The Net Withdrawl Value at End of Contract Year 3:
 
         = 11,493.76 - 450.00 - 94.44 = $10,949.32

              ADDITIONS, DELETIONS OR SUBSTITUTIONS OF INVESTMENTS


     The Company retains the right, subject to any applicable law, to make
additions to, deletions from or substitutions for the Fund shares held by any
Sub-account of the Variable Account.  The Company reserves the right to
eliminate the shares of any of the Funds and to substitute shares of another
Fund of the Fund Series, or of another open-end, registered investment company,
if the shares of the Fund are no longer available for investment, or if, in the
Company's judgment, investment in any Fund would become inappropriate in view of
the purposes of the Variable Account.  Substitutions of shares attributable to
an Owner's interest in a Sub-account will not be made until the Owner has been
notified of the change, and until the Securities and Exchange Commission has
approved the change, to the extent such notification and approval is required by
the Investment Company Act of 1940.  Nothing contained in this Statement of
Additional Information shall prevent the Variable Account from purchasing other
securities for other series or classes of contracts, or from effecting a
conversion between series or classes of contracts on the basis of requests made
by Owners.

     The Company may also establish additional Sub-accounts or series of
Sub-accounts of the Variable Account.  Each additional Sub-account would
purchase shares in a new Fund of the Fund Series or in another mutual fund.  New
Sub-accounts may be established when, in the sole discretion of the Company,
marketing needs or investment conditions warrant.  Any new Sub-accounts offered
in conjunction with the Contract will be made available to existing Owners on a
basis to be determined by the Company.  The Company may also eliminate one or
more Sub-accounts if, in its sole discretion, marketing, tax or investment
conditions so warrant.

     In the event of any such substitution or change, the Company may, by
appropriate endorsement, make such changes in the Contract as may be necessary
or appropriate to reflect such substitution or change.  If deemed to be in the
best interests of persons having voting rights under the policies, the Variable
Account may be operated as a management company under the Investment Company Act
of 1940 or it may be deregistered under such Act in the event such registration
is no longer required.



                                  REINVESTMENT


     All dividends and capital gains distributions from the Funds are
automatically reinvested in shares of the distributing Fund at their net asset
value.

<PAGE>

                                  THE CONTRACT


PURCHASE OF CONTRACTS

     The Contracts are offered to the public through brokers as well as banks
licensed under the federal securities laws and state insurance laws.  The
Contracts are distributed through the principal underwriter for the Variable
Account, Allstate Life Financial Services, Inc., an affiliate of Glenbrook Life
and Annuity Company.  The offering of the Contracts is continuous and the
Company does not anticipate discontinuing the offering of the Contracts.
However, the Company reserves the right to discontinue the offering of the
Contracts.


PERFORMANCE DATA

          From time to time the Variable Account may publish advertisements
containing performance data relating to its Sub-accounts.  The performance data
for the Sub-accounts (other than for the AIM V.I. Money Market Sub-account) will
always be accompanied by total return quotations.  Performance figures used by
the Variable Account are based on actual historical performance of its
Sub-accounts for specified periods, and the figures are not intended to indicate
future performance.  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 Funds
and the assumption that the Sub-accounts were in existence for the same periods
as those of the underlying Funds, with a level of charges equal to those
currently assessed against the Sub-accounts.

          A Sub-account's "average annual total return" represents an
annualization of the Sub-account's total return over a particular period and is
computed by finding the annual percentage rate which, when compounded annually,
will accumulate a hypothetical $1,000 Purchase Payment to the redeemable value
at the end of the one, five or ten year period, or for a period from the date of
commencement of the Sub-account's operations, if shorter than any of the
foregoing.  The average annual total return is obtained by dividing the ending
redeemable value, after deductions for any Withdrawal Charges or Contract
Maintenance Charges imposed on the Contracts by the Variable Account, by the
initial hypothetical $1,000 Purchase Payment, taking the "n"th root of the
quotient (where "n" is the number of years in the period) and subtracting 1 from
the result.

          The Withdrawal Charges assessed upon redemption are computed as 
follows: the free withdrawal amount is not assessed a withdrawal charge. 
Withdrawal charges are charged on the amount of redemption equal to the 
purchase payment, reduced by the amount of the free withdrawal amount,

                                        4

<PAGE>

if any.  The remaining amount of the redemption, if any, is not assessed a
Withdrawal Charge.  The Withdrawal Charge Schedule specifies rates based on the
number of complete years since each Purchase Payment was made.  The Contract
Maintenance Charge ($35 per contract) used in the total return calculation is
normally prorated using the following method:  The total amount of annual
Contract fees collected during the year is divided by the total average net
assets of all the Sub-accounts.  The resulting percentage is then multiplied by
the ending Contract Value.

          In addition, the Variable Account may advertise the total return over
different periods of time by means of aggregate, average, year-by-year or other
types of total return figures.  Such calculations would not reflect deductions
for Withdrawal Charges which may be imposed on the Contracts by the Variable
Account which, if reflected, would reduce the performance quoted.  The formula
for computing such total return quotations involves a per unit change
calculation.  This calculation is based on the Accumulation Unit value at the
end of the defined period divided by the Accumulation Unit value at the
beginning of such period, minus 1.  The periods included in such advertisements
are "year-to-date" (prior calendar year end to the day of the advertisement);
"year to most recent quarter" (prior calendar year end to the end of the most
recent quarter); "the prior calendar year"; "'n' most recent Calendar Years";
and "Inception (commencement of the Sub-account's operation) to date" (day of
the advertisement).

     The standard total returns for the Sub-accounts for the period of each 
Sub-account's operations during 1995 are presented below. Note that these 
total returns have not been annualized.

     From time to time, sales literature or advertisements may also quote 
average annual total returns for periods prior to the date the Variable 
Account commenced operations. Such performance information for the 
Subaccounts will be calculated based on the performance of the Portfolios and 
the assumption that the Sub-accounts were in existence for the same periods 
as those indicated for the Portfolios, with the level of Contract charges 
currently in effect.

OTHER TOTAL RETURNS

     From time to time, sales literature or advertisements may also quote 
average annual total returns that do not reflect the Surrender Charge. These 
are calculated in exactly the same way as the average annual total returns 
described above, except that the ending redeemable value of the hypothetical 
account for the period is replaced with an ending value for the period that 
does not take into account any charges on amounts surrendered. Sales

TAX-FREE EXCHANGES (1035 EXCHANGES, ROLLOVERS AND TRANSFERS)

          The Company accepts Purchase Payments which are the proceeds of a
Contract in a transaction qualifying for a tax-free exchange under Section 1035
of the Internal Revenue Code.  Except as required by federal law in calculating
the basis of the Contract, the Company does not differentiate between Section
1035 Purchase Payments and non-Section 1035 Purchase Payments.

          The Company also accepts "rollovers" and transfers from Contracts
qualifying as tax-sheltered annuities ("TSAs"), individual retirement annuities
or accounts ("IRAs"), or any other Qualified Contract which is eligible to
"rollover" into an IRA.  The Company differentiates among Non-Qualified
Contracts, TSAs, IRAs and other Qualified Contracts to the extent necessary to
comply with federal tax laws.  For example, the Company restricts the
assignment, transfer or pledge of TSAs and IRAs so the Contracts will continue
to qualify for special tax treatment.  An Owner contemplating any such exchange,
rollover or transfer of a Contract should contact a competent tax adviser with
respect to the potential effects of such a transaction.

PREMIUM TAXES

          Applicable premium tax rates depend on the Owner's state of residency
and the insurance laws and status of the Company in those states where premium
taxes are incurred.  Premium tax rates may be changed by legislation,
administrative interpretations or judicial acts.


TAX RESERVES

          The Company does not establish capital gains tax reserves for the
Sub-account nor deduct charges for tax reserves because the Company believes
that capital gains attributable to the Variable Account will not be taxable.
However, the Company reserves the right to deduct charges to establish tax
reserves for potential taxes on realized or unrealized capital gains.


                                 INCOME PAYMENTS


CALCULATION OF VARIABLE ANNUITY UNIT VALUES

          The amount of the first Income Payment is calculated by applying the
Contract Value allocated to each Variable Sub-account less any applicable
premium tax charge deducted at this time, to the income payment tables in the
Contract.  The first Variable Annuity Income Payment is divided by the
Sub-account's then current annuity unit value to determine the number of annuity
units upon which later Income Payments will be based.  Variable Annuity Income
Payments after the first will be equal to the sum of the number of annuity units
determined in this manner for each Sub-account times the then current annuity
unit value for each respective Sub-account.

          Annuity units in each variable Sub-account are valued separately and
annuity unit values will depend upon the investment experience of the particular
Portfolios in which the Sub-account invests.  The value of the annuity unit for
each variable Sub-account at the end of any Valuation Period is calculated by:
(a) multiplying the annuity unit Value at the end of the immediately preceding
Valuation Period by the Sub-accounts's Net Investment Factor during the period;
and then (b) dividing the product by the sum of 1.0 plus the assumed investment
rate for the period.  The assumed investment rate adjusts for the interest rate
assumed in the Income Payment tables used to determine the dollar amount of the
first Variable Annuity Income Payment, and is at an effective annual rate which
is disclosed in the Contract.

          The amount of the first Income Payment paid under an income plan is
determined using the interest rate and mortality table disclosed in the
Contract. Due to judicial or legislative developments regarding the use of
tables which do not differentiate on the basis of sex, different annuity tables
may be used.

                                 GENERAL MATTERS


INCONTESTABILITY

          The Contract will not be contested after it is issued.


SETTLEMENTS

          Due proof of the Owner(s) death (or Annuitant's death if there is a
non-natural Owner) must be received prior to settlement of a death claim.


SAFEKEEPING OF THE VARIABLE ACCOUNT'S ASSETS

          The Company holds title to the assets of the Variable Account.  The
assets are kept physically segregated and held separate and apart from the
Company's general corporate assets.  Records are maintained of all purchases and
redemptions of the Fund shares held by each of the variable Sub-accounts.

          The Fund does not issue certificates and, therefore, the Company holds
the Account's assets in open account in lieu of stock certificates.  See the
Fund's prospectus for a more complete description of the custodian of the Fund.



                               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 GLENBROOK LIFE AND ANNUITY COMPANY

                                        7

<PAGE>

          The Company is taxed as a life insurance company under Part I of
Subchapter L of the Internal Revenue Code.  Since the Variable Account is not an
entity separate from the Company, and its operations form a part of the Company,
it will not be taxed separately as a "Regulated Investment Company" under
Subchapter M of the Code.  Investment income and realized capital gains are
automatically applied to increase reserves under the contract.  Under existing
federal income tax law, the Company believes that the Variable Account
investment income and realized net capital gains will not be taxed to the extent
that such income and gains are applied to increase the reserves under the
contract.

          Accordingly, the Company does not anticipate that it will incur any
federal income tax liability attributable to the Variable Account, and therefore
the Company does not intend to make provisions for any such taxes.  However, if
changes in the federal tax laws or interpretations thereof result in the Company
being taxed on income or gains attributable to the Variable Account, then the
Company may impose a charge against the Variable Account (with respect to some
or all contracts) in order to set aside provisions to pay such taxes.

EXCEPTIONS TO THE NON-NATURAL OWNER RULE

          There are several exceptions to the general rule that contracts held
by a non-natural owner are not treated as annuity contracts for federal income
tax purposes.  Contracts will generally be treated as held by a natural person
if the nominal owner is a trust or other entity which holds the contract as
agent for a natural person.  However, this special exception will not apply in
the case of an employer who is the nominal owner of an annuity contract under a
non-qualified deferred compensation arrangement for its employees.  Other
exceptions to the non-natural owner rule are: (1) contracts acquired by  an
estate of a decedent by reason of the death of the decedent; (2) certain
qualified contracts; (3) contracts purchased by employers upon the termination
of certain qualified plans; (4) certain contracts used in connection with
structured settlement agreements, and (5) contracts purchased with a single
premium when the annuity starting date is no later than a year from purchase of
the annuity and substantially equal periodic payments are made, not less
frequently than annually, during the annuity period.


IRS REQUIRED DISTRIBUTION AT DEATH RULES

          In order to be considered an annuity contract for federal income tax
purposes, an annuity contract must provide: (1) if any owner dies on or after
the annuity start date but before the entire interest in the contract has been
distributed, the remaining portion of such interest must be distributed at least
as rapidly as under the method of distribution being used as of the date of the
owner's death; (2) if any owner dies prior to the annuity start date, the entire
interest in the contract will be distributed within five years after the date of
the owner's death.  These requirements are satisfied if any portion of the
owner's interest which is payable to (or for the benefit of) a designated
beneficiary is distributed over the life of such beneficiary (or over a period

                                        8

<PAGE>

not extending beyond the life expectancy of the beneficiary) and the
distributions begin within one year of the owner's death.  If the owner's
designated beneficiary is the surviving spouse of the owner, the contract may be
continued with the surviving spouse as the new owner.  If the owner of the
contract is a non-natural person, then the annuitant will be treated as the
owner for purposes of applying the distribution at death rules.  In addition, a
change in the annuitant on a contract owned by a non-natural person will be
treated as the death of the owner.

QUALIFIED PLANS

          This annuity contract may be used with several types of qualified
plans.  The tax rules applicable to participants in such qualified plans vary
according to the type of plan and the terms and conditions of the plan itself.
Adverse tax consequences may result from excess contributions, premature
distributions, distributions that do not conform to specified commencement and
minimum distribution rules, excess distributions and in other circumstances.
Owners and participants under the plan and annuitants and beneficiaries under
the contract may be subject to the terms and conditions of the plan regardless
of the terms of the contract.


TYPES OF QUALIFIED PLANS

                         INDIVIDUAL RETIREMENT ANNUITIES

          Section 408 of the Code permits eligible individuals to contribute to
an individual retirement program known as an Individual Retirement Annuity.
Individual Retirement Annuities are subject to limitations on the amount that
can be contributed and on the time when distributions may commence.  Certain
distributions from other types of qualified plans may be "rolled over" on a
tax-deferred basis into an Individual Retirement Annuity.  IRAs generally may
not provide life insurance, but they may provide a death benefit that equals the
greater of the premiums paid and the contract's cash value.  The contract
provides a death benefit that in certain circumstances may exceed the greater of
the payments and the contract value.  It is possible that the Death Benefit
could be viewed as violating the prohibition on investment in life insurance
contracts with the result that the Contract would not be viewed as satisfying
the requirements of an IRA.

                                        9

<PAGE>

                        SIMPLIFIED EMPLOYEE PENSION PLANS

          Section 408(k) of the Code allows employers to establish simplified
employee pension plans for their employees using the employees' individual
retirement annuities if certain criteria are met.  Under these plans the
employer may, within specified limits, make deductible contributions on behalf
of the employees to their individual retirement annuities.  Employers intending
to use the contract in connection with such plans should seek competent advice.
In particular, employers should consider that IRAs generally may not provide
life insurance, but they may provide a death benefit that equals the greater of
the premiums paid and the contract's cash value.  The contract provides a death
benefit that in certain circumstances may exceed the greater of the payments and
the contract value.  It is possible that the death benefit could be viewed as 
violating the prohibition on investment in life insurance contracts with the 
result that the contract would not be viewed as satisfying the requirements 
of the IRS.


                             TAX SHELTERED ANNUITIES

          Section 403(b) of the Code permits public school employees and
employees of certain types of tax-exempt organizations (specified in Section
501(c)(3) of the Code) to have their employers purchase annuity contracts for
them, and subject to certain limitations, to exclude the purchase payments from
the employees' gross income.  An annuity contract used for a Section 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 the account of hardship (earnings on salary reduction
contributions may not be distributed for 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) plan.  Purchasers of the contracts
for such purposes should seek competent advice as to eligibility, limitations on
permissible amounts of purchase payments and other tax consequences associated
with the contracts.  In particular, purchasers should consider that the contract
provides a death benefit that in certain circumstances may exceed the greater of
the payments and the contract value.  It is possible that such death benefit
could be characterized as an incidental death benefit.  If the death benefit
were so characterized, this could result in currently taxable income to
purchasers.  In addition, there are limitations on the amount of incidental
death benefits that may be provided under a tax-sheltered annuity.  Even if the
death benefit under the contract were characterized as an incidental death
benefit, it is unlikely to violate those limits unless the purchaser also
purchases a life insurance contract as part of his or her tax-sheltered annuity
plan.


          CORPORATE AND SELF-EMPLOYED PENSION AND PROFIT SHARING PLANS

          Sections 401(a) and 403(a) of the Code permit corporate employers to
establish various types of tax favored retirement plans for employees.  The
Self-Employed Individuals Retirement Act of 1962, as amended, (commonly referred
to as "H.R. 10" or "Keogh") permits self-employed individuals to establish tax
favored retirement plans for themselves and their

                                       10
<PAGE>

employees.  Such retirement plans may permit the purchase of annuity contracts
in order to provide benefits under the plans.  The contract provides a death
benefit that in certain circumstances may exceed the greater of the payments and
the contract value.  It is possible that such death benefit could be
characterized as an incidental death benefit.  There are limitations on the
amount of incidental benefits that may be provided under pension and profit
sharing plans.  In addition, the provision of such benefits may result in
currently taxable income to participants.  Employers intending to use the
contract in connection with such plans should seek competent advice.


             STATE AND LOCAL GOVERNMENT AND TAX-EXEMPT ORGANIZATION
                           DEFERRED COMPENSATION PLANS

          Section 457 of the Code permits employees of state and local
governments and tax-exempt organizations to defer a portion of their
compensation without paying current taxes.  The employees must be participants
in an eligible deferred compensation plan.  Under these plans, contributions
made for the benefit of the employees will not be includible in the employees'
gross income until distribution from the plan.  However, under a Section 457
plan all the compensation deferred under the plan must remain solely the
property of the employer, subject only to the claims of the employer's general
creditors, until such time as made available to the employee or a beneficiary.

Capital Appreciation, Diversified Income, Global Utilities, Government
Securities, Growth, Growth & Income, International Equity, Money Market, and
Value Funds that comprise the Account.  These financial statements are the
responsibility of the Account's management.  Our responsibility is to express 
an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing

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.  Our 
procedures included confirmation of securities owned at December 31, 1995.  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 audit provides a reasonable basis 
for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Account as of December 31, 1995, and 
the results of its operations and the changes in net assets of each of the 
funds comprising the Account, for the period from December 4, 1995 (date 
operations commenced), to December 31, 1995, in conformity with generally 
accepted accounting principles.

              GLENBROOK LIFE AND ANNUITY COMPANY SEPARATE ACCOUNT A
                          NOTES TO FINANCIAL STATEMENTS
        FOR THE PERIOD FROM DECEMBER 4, 1995 (DATE OPERATIONS COMMENCED)
                              TO DECEMBER 31, 1995


1.   ORGANIZATION

     Glenbrook Life and Annuity Company Separate Account A (the "Account"), a 
unit investment trust registered with the Securities and Exchange Commission 
under the Investment Company Act of 1940, is a Separate Account of Glenbrook 
Life and Annuity Company ("Glenbrook Life"), which is wholly owned by Allstate 
Life Insurance Company ("Allstate Life"), a wholly-owned subsidiary of Allstate
Insurance Company ("Allstate"), which is wholly owned by The Allstate
Corporation (the "Corporation").  The Account was established on September 6,
1995, by resolution of the Board of Directors of Glenbrook Life and began
accepting contractholder deposits on December 4, 1995.

     Glenbrook Life writes certain annuity contracts, the proceeds of which are
invested at the discretion of the contractholder.  Contractholders primarily
invest in units of the portfolios comprising the Account, for which they bear
investment risk.  The Account, in turn, invests solely in shares of the
portfolios of the AIM Variable Insurance Funds ("Fund").  The contractholder may
also invest in the general account of Glenbrook Life ("Fixed Account").
Glenbrook Life provides administrative and insurance services to the Account for
a fee.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Valuation of investments

     Investments consist of shares in the portfolios of the Fund, and are stated
at fair value based on quoted market prices.

Recognition of investment income

     Investment income consists of dividends declared by the portfolios of the
Fund, and is recognized on the date of record.

Realized gains and losses

     Realized gains and losses on the sale of shares by the Account are computed
on a weighted average cost ("cost") basis.


                                    F-6

              GLENBROOK LIFE AND ANNUITY COMPANY SEPARATE ACCOUNT A
                          NOTES TO FINANCIAL STATEMENTS
        FOR THE PERIOD FROM DECEMBER 4, 1995 (DATE OPERATIONS COMMENCED)
                              TO DECEMBER 31, 1995


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Contractholder account activity

     Account activity is reflected in individual contractholder accounts on a
daily basis.

   
     For each year or portion of a year a contract is in effect, Glenbrook 
Life deducts a fixed annual contract maintenance charge of $35 as 
reimbursement for expenses related to the maintenance of each contract and 
the Account.  The amount of this charge is guaranteed not to increase over 
the life of the contract.  This charge is 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.
    

Federal income taxes

     Net investment income and realized gains and losses on investments of the
Account are taxable to the contractholders, generally upon distribution. 
Accordingly, no provision for income taxes has been recorded.

3.   MORTALITY AND EXPENSE CHARGES

     Glenbrook Life assumes mortality and expense risks related to the
operations of the Account and deducts charges daily at a rate, on an annual
basis, equal to 1.35% of the daily net assets of the Account.  Glenbrook Life
guarantees that the amount of this charge will not increase over the life of the
contract.

4.   ADMINISTRATIVE EXPENSE CHARGE

     Glenbrook Life deducts administrative expense charges daily at a rate, on
an annual basis, equal to .10% of the daily net assets of the Account.  This
charge is designed to cover additional administrative expenses.

27. NUMBER OF CONTRACT OWNERS

     As of December 31, 1995 there were 2 non-qualified contracts in force.
    

28. INDEMNIFICATION

   
     The by-laws of both Glenbrook Life and Annuity Company (Depositor) and
Allstate Life Financial Services, Inc. (Principal Underwriter), provide for the
indemnification of its Directors, Officers and Controlling Persons, against
expenses, judgments, fines and amounts paid in settlement as incurred by such
person, if such person acted properly.  No indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable for negligence or misconduct in the performance of a duty
to the Company, unless a court determines such person is entitled to such
indemnity.
    

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

of life insurance companies to fund benefits under variable annuity contracts;
and

      WHEREAS, AVIF will make Shares of each Series listed on Schedule A hereto

<PAGE>

   

      WHEREAS, the Accounts may be divided into two or more subaccounts
("Subaccounts"; reference herein to an "Account" includes reference to each

      WHEREAS, Glenbrook will serve as the depositor of the Accounts, each of

and redemption at net asset value and with no sales charges, subject to the
terms and conditions of this Agreement.  The Board of Directors of AVIF may
refuse to sell Shares of any Fund to any person, or suspend or terminate the
offering of Shares of any Fund if such action is required by law or by
regulatory authorities having jurisdiction or if, in the sole discretion of the
Directors acting in good faith and in light of their fiduciary duties under
federal and any applicable state laws, such action is deemed in the best
interests of the shareholders of such Fund.

<PAGE>

   

      1.2     ADDITION, DELETION OR MODIFICATION OF FUNDS.

      The Parties hereto may agree, from time to time, to add other Funds to
provide additional funding media for the Policies, or to delete, combine, or
modify existing Funds, by amending Schedule A hereto.  Upon such amendment to
Schedule A, any applicable reference to a Fund, AVIF, or its Shares herein shall
include a reference to any such additional Fund.  Schedule A, as amended from
time to time, is incorporated herein by reference and is a part hereof.


      1.3     NO SALES TO THE GENERAL PUBLIC.

      AVIF represents and warrants that no Shares of any Fund have been or will
be sold to the general public.



                         SECTION 2.  PROCESSING TRANSACTIONS


      2.1     TIMELY PRICING AND ORDERS.

      (a) AVIF or its designated agent will use its best efforts to provide
Glenbrook with the net asset value per Share for each Fund by 6:00 p.m. Central
time on each Business Day.  As used herein, "Business Day" shall mean any day on
which (i) the New York Stock Exchange is open for regular trading and (ii) AVIF
calculates the Fund's net asset value.

      (b) Glenbrook will use the data provided by AVIF each Business Day
pursuant to paragraph (a) immediately above to calculate Account unit values and
to process transactions that receive that same Business Day's Account unit
values.  Glenbrook will perform such Account processing the same Business Day,
and will place corresponding orders to purchase or redeem Shares with AVIF by 9
a.m. Central time the following Business Day; PROVIDED, however, that AVIF shall
provide additional time to Glenbrook in the event that AVIF is unable to meet
the 6:00 p.m. time stated in paragraph (a) immediately above.  Such additional
time shall be equal to the additional time that AVIF takes to make the net asset
values available to Glenbrook.

      (c) Each order to purchase or redeem Shares will separately describe the
amount of Shares of each Fund to be purchased, redeemed or exchanged and will
not be netted; PROVIDED, however, with respect to payment of the purchase price
by Glenbrook and of redemption proceeds by AVIF, Glenbrook and AVIF shall net
purchase and redemption orders with respect to each Fund and shall transmit one
net payment per Fund in accordance with Section 2.2, below.  Each order to
purchase or redeem Shares shall also specify whether the order results from
purchase payments, surrenders,


                                          3

    

<PAGE>

   

partial withdrawals, routine withdrawals of charges, or requests for other
transactions under Policies (collectively, "Policy transactions").

      (d) If AVIF provides materially incorrect Share net asset value
information, Glenbrook shall be entitled to an adjustment to the number of
Shares purchased or redeemed to reflect the correct net asset value per Share.
Any material error in the calculation or reporting of net asset value per Share,
dividend or capital gain information shall be reported promptly upon discovery
to Glenbrook.  Materiality and reprocessing cost reimbursement shall be
determined in accordance with standards established by the parties as provided
in Schedule B, attached hereto and incorporated herein.


      2.2     TIMELY PAYMENTS.

      Glenbrook will wire payment for net purchases to a custodial account
designated by AVIF by 1:00 p.m. Central Time on the same day as the order for
Shares is placed, to the extent practicable.  AVIF will wire payment for net
redemptions to an account designated by Glenbrook by 1:00 p.m. Central Time on
the same day as the Order is placed, to the extent practicable, but in any event
within five calendar days after the date the order is placed in order to enable
Glenbrook to pay redemption proceeds within the time specified in Section 22(e)
of the 1940 Act or such shorter period of time as may be required by law.


      2.3     APPLICABLE PRICE.

      (a) Share purchase and redemption orders that result from Policy
transactions and that Glenbrook receives prior to the close of regular trading
on the New York Stock Exchange on a Business Day will be executed at the net
asset values of the appropriate Funds next computed after receipt by AVIF or its
designated agent of the orders.  For purposes of this Section 2.3(a), Glenbrook
shall be the designated agent of AVIF for receipt of orders relating to Policy
transactions on each Business Day and receipt by such designated agent shall
constitute receipt by AVIF; PROVIDED, that AVIF receives notice of such orders
by 9 a.m. Central time on the next following Business Day or such later time
computed in accordance with Section 2.1(b) hereof.

      (b) All other Share purchases and redemptions by Glenbrook will be
effected at the net asset values of the appropriate Funds next computed after
receipt by AVIF or its designated agent of the order therefor, and such orders
will be irrevocable.


      2.4     DIVIDENDS AND DISTRIBUTIONS.

      AVIF will furnish notice promptly to Glenbrook of any income dividends or
capital gain distributions payable on the Shares of any Fund.  Glenbrook hereby
elects to reinvest all dividends


                                          4

    

<PAGE>

   

and capital gains distributions in additional Shares of the corresponding Fund
at the ex-dividend date net asset values until Glenbrook otherwise notifies AVIF
in writing, it being agreed by the Parties that the ex-dividend date and the
payment date with respect to any dividend or distribution will be the same
Business Day.  Glenbrook reserves the right to revoke this election and to
receive all such income dividends and capital gain distributions in cash.

      3.1     GENERAL.

and made a part  hereof, each Party will bear all expenses incident to its

                             SECTION 4.  LEGAL COMPLIANCE


      4.1     TAX LAWS.

      (a)     AVIF represents and warrants that each Fund is currently
qualified and will continue to qualify as a regulated investment company ("RIC")
under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code").  AVIF will notify Glenbrook immediately upon having a reasonable basis
for believing that a Fund has ceased to so qualify or that it might not so
qualify in the future.


                                          5

      (b)     AVIF represents that it will comply and maintain each Fund's
compliance with the diversification requirements set forth in Section 817(h) of
the Code and Section 1.817-5(b) of the regulations under the Code. AVIF will
notify Glenbrook immediately upon having a reasonable basis for believing that a
Fund has ceased to so comply or that a Fund might not so comply in the future.

      (c)  Glenbrook agrees that if the Internal Revenue Service ("IRS")
asserts in writing in connection with any governmental audit or review of
Glenbrook or, to Glenbrook's knowledge, of any Policy owner, annuitant or
participant under the Policies (collectively, "Participants"), that any Fund has
failed to comply with the diversification requirements of section 817(h) of the
Code or Glenbrook otherwise becomes aware of any facts that could give rise to
any claim against AVIF or its affiliates as a result of such a failure or
alleged failure to so comply with section 817(h) (hereinafter respectively
referred to in this paragraph (c) as "failure" or "alleged failure"):

       (i) Glenbrook shall promptly notify AVIF of such assertion or potential
      claim;

       (ii) Glenbrook shall consult with AVIF as to how to minimize any
      liability that may arise as a result of such failure or alleged failure;

      (iii) Glenbrook shall use its best efforts to minimize any liability of
      AVIF or its affiliates resulting from such failure, including, without
      limitation, demonstrating, pursuant to Treasury Regulations Section
      1.817-5(a)(2), to the Commissioner of the IRS that such failure was
      inadvertent, PROVIDED that Glenbrook shall not be required to make any
      such demonstration of inadvertence unless AVIF represents or provides an
      opinion of counsel, which representation or opinion shall be reasonably
      satisfactory to Glenbrook, to the effect  that a reasonable basis exists
      for making such a demonstration;

       (iv) Glenbrook shall permit AVIF, its affiliates and their legal and
      accounting advisors to attend, advise and otherwise assist Glenbrook
      (which assistance Glenbrook shall consider and/or accept in good faith)
      with respect to any conferences, settlement discussions or other
      administrative or judicial proceeding or contests (including judicial
      appeals thereof) with the IRS, any Participant or any other claimant
      regarding any claims that could give rise to liability to AVIF or its
      affiliates as a result of such a failure or alleged failure, PROVIDED
      that Glenbrook shall control, in good faith, the conduct of such
      conferences, discussions, proceedings, or contests or appeals thereof;

      (v) any written materials to be submitted by Glenbrook to the IRS, any
      Participant or any other claimant in connection with any of the foregoing
      proceedings or contests (including, without limitation, any such
      materials to be submitted to the IRS pursuant to Treasury Regulations
      Section 1.817-5(a)(2)), (a) shall be provided by Glenbrook to AVIF
      (together with any supporting information or analysis) at least ten (10)
      business days, or such shorter period to which the Parties hereto may
      from time to time agree,  prior to the day on which such proposed
      materials are to be submitted and (b) shall not be submitted by Glenbrook
      to


                                          6

    

<PAGE>

   

any such person without the express written consent of AVIF which shall not be
unreasonably withheld;

      (vi) Glenbrook shall provide AVIF or its affiliates and their accounting
      and legal advisors with such cooperation as AVIF shall reasonably request
      (including, without limitation, by providing AVIF and its accounting and
      legal advisors with copies of any relevant books and records (or portions
      thereof) of Glenbrook that may be reasonably requested by or on behalf of
      AVIF and that Glenbrook is permitted to provide in accordance with
      applicable law) in order to facilitate review by AVIF or its advisors of
      any written submissions provided to it pursuant to the preceding clause
      or its assessment of the validity or amount of any claim against its
      arising from such a failure or alleged failure;

      (vii) Glenbrook shall not with respect to any claim of the IRS or any
      Participant that would give rise to a claim against AVIF or its
      affiliates (a) compromise or settle any claim, (b) accept any adjustment
      on audit, or (c) forego any allowable administrative or judicial appeals,
      without the express written consent of AVIF or its affiliates, which
      shall not be unreasonably withheld, PROVIDED that Glenbrook shall not be
      required, after exhausting all administrative remedies,  to appeal any
      adverse IRS or judicial decision unless AVIF or its affiliates shall have
      provided an opinion of counsel approved by Glenbrook, which approval
      shall not be unreasonably withheld, to the effect that a reasonable basis
      exists for taking such appeal (or, in the case of an appeal to the United
      States Supreme Court, that Glenbrook should be more likely than not to
      prevail on such appeal),  and PROVIDED FURTHER that each Party shall bear
      one-half of the expenses of any judicial appeal; and

       (viii) AVIF and its affiliates shall have no liability as a result of
      such failure or alleged failure if Glenbrook fails to comply with any of
      the foregoing clauses (i) through (vii), and such failure could be shown
      to have materially contributed to the liability.

      Should AVIF or any of its affiliates refuse to give its written consent
to any compromise or settlement of any claim or liability hereunder, Glenbrook
may, in its discretion, authorize AVIF or its affiliates to act in the name of
Glenbrook in, and to control the conduct of, such conferences, discussions,
proceedings, contests or appeals and all administrative or judicial appeals
thereof, and in that event AVIF or its affiliates shall bear the fees and
expenses associated with the conduct of the proceedings that it is so authorized
to control; PROVIDED that in no event shall Glenbrook have liability resulting
from AVIF's refusal to accept the proposed settlement or compromise with respect
to any failure caused by AVIF.  As used in this Agreement, the term "affiliates"
shall have the same meaning as "affiliated person" as defined in Section 2(a)(3)
of the 1940 Act.

      (d)     Glenbrook represents and warrants that the Policies currently are
and at all times  will be treated as annuity, endowment, or life insurance
contracts under applicable provisions of the Code.  Glenbrook will notify AVIF
immediately upon having a reasonable basis for believing that any of the
Policies have ceased to be so treated or that they might not be so treated in
the future,


                                          7

    

<PAGE>

   

provided that such notice shall be kept confidential during the period of
Glenbrook's investigation of any such circumstances to the extent permitted by
applicable law.

      (e)     Glenbrook represents and warrants that each Account is and at all
times will be a "segregated asset account" and that interests in each Account
are offered exclusively through the purchase of or transfer into a "variable
contract," within the meaning of such terms under Section 817 of the Code and
the regulations thereunder.  Glenbrook  will notify AVIF immediately upon having
a reasonable basis for believing that such requirements have ceased to be met or
that they might not be met in the future.


      4.2     INSURANCE AND CERTAIN OTHER LAWS.

      (a)     AVIF and AIM will use their best efforts to comply with any
applicable state insurance laws or regulations, to the extent specifically

perform its duties and comply with its obligations under this Agreement.

duly organized, validly existing, and in good standing under the laws of the
State of Delaware and has full power, authority, and legal right to execute,
deliver, and perform its duties and comply with its obligations under this
Agreement.

      (e)     The Underwriter represents and warrants that it is a Delaware
corporation duly organized, validly existing, and in good standing under the
laws of the State of Delaware and has full power, authority, and legal right to
execute, deliver, and perform its duties and comply with its obligations under
this Agreement.


      4.3     SECURITIES LAWS.

                         SECTION 5.  MIXED AND SHARED FUNDING


      5.1     GENERAL.

      AVIF has applied for an order from the SEC exempting it from certain
provisions of the 1940 Act and rules thereunder so that AVIF may be available
for investment by certain other entities, including, without limitation,
separate accounts funding variable life insurance contracts, separate accounts
of insurance companies unaffiliated with Glenbrook, and trustees of qualified
pension and retirement plans (collectively, "Mixed and Shared Funding").  The
Parties recognize that the SEC has imposed terms and conditions for such orders
that are substantially identical to many of the provisions of this Section 5.
Sections 5.2 through 5.8 below shall apply, if and only if AVIF implements Mixed
and Shared Funding, pursuant to such an exemptive order or otherwise.  AVIF
hereby notifies Glenbrook that, in the event that AVIF implements Mixed and
Shared Funding, it may be appropriate to include in the prospectus pursuant to
which a Policy is offered disclosure regarding the potential risks of Mixed and
Shared Funding.


      5.2     DISINTERESTED DIRECTORS.

      AVIF agrees that its Board of Directors shall at all times consist of
directors a majority of whom (the "Disinterested Directors") are not interested
persons of AVIF within the meaning of Section 2(a)(19) of the 1940 Act and the
Rules thereunder and as modified by any applicable orders of the SEC, except
that if this condition is not met by reason of the death, disqualification, or
bona fide resignation of any director, then the operation of this condition
shall be suspended (a) for a period of 45 days if the vacancy or vacancies may
be filled by the Board; (b) for a period of 60 days if a vote of shareholders is
required to fill the vacancy or vacancies; or (c) for such longer period as the
SEC may prescribe by order upon application.


                                          12

    

<PAGE>

   

      5.3     MONITORING FOR MATERIAL IRRECONCILABLE CONFLICTS.

      AVIF agrees that its Board of Directors will monitor for the existence of
any material irreconcilable conflict between the interests of the participants
in all separate accounts of life insurance companies utilizing AVIF
("Participating Insurance Companies"), including each Account  and participants
on all qualified retirement and pension plans investing in AVIF ("Participating
Plans").  Glenbrook agrees to inform the Board of Directors of AVIF of the
existence of or any potential for any such material irreconcilable conflict of
which it is aware.  The concept of a "material irreconcilable conflict" is not
defined by the 1940 Act or the rules thereunder, but the Parties recognize that
such a conflict may arise for a variety of reasons, including, without
limitation:

      (a)  an action by any state insurance or other regulatory authority;

      (b)  a change in applicable federal or state insurance, tax or securities
laws or regulations, or a public ruling, private letter ruling, no-action or
interpretative letter, or any similar action by insurance, tax or securities
regulatory authorities;

      (c)  an administrative or judicial decision in any relevant proceeding;

      (d)  the manner in which the investments of any Fund are being managed;

      (e)  a difference in voting instructions given by variable annuity
contract and variable life insurance contract Participants or by Participants of
different Participating Insurance Companies;

      (f)  a decision by a Participating Insurance Company to disregard the
voting instructions of Participants; or

      (g) a decision by a Participating Plan to disregard the voting
instructions of  Plan participants.

      Consistent with the SEC's requirements in connection with exemptive
orders of the type referred to in Section 5.1 hereof, Glenbrook will assist the
Board of Directors in carrying out its responsibilities by providing the Board
of Directors with all information reasonably necessary for the Board of
Directors to consider any issue raised, including information as to a decision
by Glenbrook to disregard voting instructions of Participants.


      5.4     CONFLICT REMEDIES.

      (a)     It is agreed that if it is determined by a majority of the
members of the Board of Directors or a majority of the Disinterested Directors
that a material irreconcilable conflict exists, Glenbrook will, if it is a
Participating Insurance Company for which a material irreconcilable


                                          13

    

<PAGE>

   

conflict is relevant, at its own expense and to the extent reasonably
practicable (as determined by a majority of the Disinterested Directors), take
whatever steps are necessary to remedy or eliminate the material irreconcilable
conflict, which steps may include, but are not limited to:

      (i)     withdrawing the assets allocable to some or all of the Accounts
              from AVIF or any Fund and reinvesting such assets in a different
              investment medium, including another Fund of AVIF, or submitting
              the question whether such segregation should be implemented to a
              vote of all affected Participants and, as appropriate,
              segregating the assets of any particular group (E.G., annuity
              Participants, life insurance Participants) that votes in favor of
              such segregation, or offering to the affected Participants the
              option of making such a change; and

      (ii)    establishing a new registered investment company of the type
              defined as a "management company" in Section 4(3) of the 1940 Act
              or a new separate account that is operated as a management
              company.

      (b)     If the material irreconcilable conflict arises because of
Glenbrook's decision to disregard Participant voting instructions and that
decision represents a minority position or would preclude a majority vote,
Glenbrook may be required, at AVIF's election, to withdraw each Account's
investment in AVIF or any Fund.  No charge or penalty will be imposed as a
result of such withdrawal.  Any such withdrawal must take place within six
months after AVIF gives notice to Glenbrook that this provision is being
implemented, and until such withdrawal AVIF shall continue to accept and
implement orders by Glenbrook for the purchase and redemption of Shares of AVIF.

      (c)     If a material irreconcilable conflict arises because a particular
state insurance regulator's decision applicable to Glenbrook conflicts with the
majority of other state regulators, then Glenbrook will withdraw each Account's
investment in AVIF within six months after AVIF's Board of Directors informs
Glenbrook that it has determined that such decision has created a material
irreconcilable conflict (after consideration of the interests of all
Participants), and until such withdrawal AVIF shall continue to accept and
implement orders by Glenbrook for the purchase and redemption of Shares of AVIF.

      (d)     Glenbrook agrees that any remedial action taken by it in
resolving any material irreconcilable conflict will be carried out at its
expense and with a view only to the interests of Participants.

      (e)     For purposes hereof, a majority of the Disinterested Directors
will determine whether or not any proposed action adequately remedies any
material irreconcilable conflict.  In no event, however, will AVIF or any of its
affiliates be required to establish a new funding medium for any Policies.
Glenbrook will not be required by the terms hereof to establish a new funding
medium for any Policies if an offer to do so has been declined by vote of a
majority of Participants materially adversely affected by the material
irreconcilable conflict.

      5.5     NOTICE TO GLENBROOK.

      AVIF will promptly make known in writing to Glenbrook the Board of
Directors' determination of the existence of a material irreconcilable conflict,
a description of the facts that give rise to such conflict and the implications
of such conflict.


      5.6     INFORMATION REQUESTED BY BOARD OF DIRECTORS.

      Glenbrook and AVIF (or its investment adviser) will at least annually
submit to the Board of Directors of AVIF such reports, materials or data as the
Board of Directors may reasonably request so that the Board of Directors may
fully carry out the obligations imposed upon it by the provisions hereof or any
exemptive application filed with the SEC to permit Mixed and Shared Funding, and
said reports, materials and data will be submitted at any reasonable time deemed
appropriate by the Board of Directors.  All reports received by the Board of
Directors of potential or existing conflicts, and all Board of Directors actions
with regard to determining the existence of a conflict, notifying Participating
Insurance Companies of a conflict, and determining whether any proposed action
adequately remedies a conflict, will be properly recorded in the minutes of the
Board of Directors or other appropriate records, and such minutes or other
records will be made available to the SEC upon request.


      5.7     COMPLIANCE WITH SEC RULES.

      If, at any time during which AVIF is serving as an investment medium for
variable life insurance Policies, 1940 Act Rules 6e-3(T) or, if applicable, 6e-2
are amended or Rule 6e-3 is adopted to provide exemptive relief with respect to
Mixed and Shared Funding, AVIF agrees that it will comply with the terms and
conditions thereof and that the terms of this Section 5 shall be deemed modified
if and only to the extent required in order also to comply with the terms and
conditions of such exemptive relief that is afforded by any of said rules that
are applicable.





      5.8     REQUIREMENTS FOR OTHER INSURANCE COMPANIES.

      AVIF will require that each Participating Insurance Company enter into an
agreement with AVIF that contains in substance the same provisions as are set
forth in Sections 4.1(b), 4.1(d), 4.3(a), 4.4(b), 4.5(a), 5, and 10 of this
Agreement.

                               SECTION 6.  TERMINATION


      6.1     EVENTS OF TERMINATION.

      Subject to Section 6.4 below, this Agreement will terminate as to a Fund:

      (a)     at the option of AVIF or Glenbrook upon the approval by (i) a
majority of the Disinterested Directors or (ii) a majority vote of the Shares of
the affected Fund that are held in the corresponding Subaccount of an Account
(pursuant to the procedures set forth in Section 10 of this Agreement for voting
Shares in accordance with Participant instructions); or

      (b)     at the option of AVIF or AIM upon institution of formal
proceedings against Glenbrook or its affiliates by the NASD, the SEC, any state
insurance regulator or any other regulatory body regarding Glenbrook's
obligations under this Agreement or related to the sale of the Policies, the
operation of each Account, or the purchase of Shares, if, in each case, AVIF or
AIM reasonably determines that such proceedings, or the facts on which such
proceedings would be based, have a material likelihood of imposing material
adverse consequences on the Fund with respect to which the Agreement is to be
terminated; or

      (c)     at the option of Glenbrook upon institution of formal proceedings
against AVIF, its principal underwriter, or its investment adviser by the NASD,
the SEC, or any state insurance regulator or any other regulatory body regarding
AVIF's obligations under this Agreement or related to the operation or
management of AVIF or the purchase of AVIF Shares, if, in each case, Glenbrook
reasonably determines that such proceedings, or the facts on which such
proceedings would be based, have a material likelihood of imposing material
adverse consequences on Glenbrook, or the Subaccount corresponding to the Fund
with respect to which the Agreement is to be terminated; or

      (d)     at the option of any Party in the event that (i) the Fund's
Shares are not registered and, in all material respects, issued and sold in
accordance with any applicable federal or state law or (ii) such law precludes
the use of such Shares as an underlying investment medium of the Policies issued
or to be issued by Glenbrook; or

      (e)     upon termination of the corresponding Subaccount's investment in
the Fund pursuant to Section 5 hereof; or

      (f)     at the option of Glenbrook if the Fund ceases to qualify as a RIC
under Subchapter M of the Code or under successor or similar provisions, or if
Glenbrook reasonably believes that the Fund may fail to so qualify;


                                          16

    

<PAGE>

   

      (g)     at the option of Glenbrook if the Fund fails to comply with
Section 817(h) of the Code or with successor or similar provisions (other than
by reason of the failure of the Policies issued by Glenbrook to qualify as
annuity or life insurance contracts under the Code, or the failure of any
Account or Policy to meet the definition of "segregated asset account" or
"variable contract"; respectively, within the meaning of the Code), or if
Glenbrook reasonably believes that the Fund may fail to so comply; or

      (h)     at the option of AVIF or AIM if the Policies issued by Glenbrook
cease to qualify as annuity contracts or life insurance contracts under the Code
(other than by reason of the Fund's noncompliance with Section 817(h) or
Subchapter M of the Code) or if interests in an Account under the Policies are
not registered, where required, and, in all material respects, are not issued or
sold in accordance with any applicable federal or state law; or

      (i) upon another Party's material breach of any provision of this
Agreement.


      6.2     NOTICE REQUIREMENT FOR TERMINATION.

      No termination of this Agreement will be effective unless and until the
Party terminating this Agreement gives prior written notice to the other Party
to this Agreement of its intent to terminate, and such notice shall set forth
the basis for such termination.  Furthermore:

      (a)     in the event that any termination is based upon the provisions of
Section 6.1(a) or 6.1(e) hereof, such prior written notice shall be given at
least six (6) months in advance of the effective date of termination unless a
shorter time is agreed to by the Parties hereto;

      (b)     in the event that any termination is based upon the provisions of
Section 6.1(b) or Section 6.1(c) hereof, such prior written notice shall be
given at least ninety (90) days in advance of the effective date of termination
unless a shorter time is agreed to by the Parties hereto; and

      (c)     in the event that any termination is based upon the provisions of
Section 6.1(d), Section 6.1(f), Section 6.1(g), Section 6.1(h) or Section 6.1(i)
hereof, such prior written notice shall be given as soon as possible within
twenty-four (24) hours after the terminating Party learns of the event causing
termination to be required.




      6.3     FUNDS TO REMAIN AVAILABLE.

      Except (a) as necessary to implement Participant-initiated transactions,
(b) as required by state insurance laws or regulations, (c) as required pursuant
to Section 5 of this Agreement, or (d)


                                          17

    

<PAGE>

   

with respect to any Fund as to which this Agreement has terminated pursuant to
Section 6.1 hereof, Glenbrook shall not (i) redeem AVIF Shares attributable to
the Policies (as opposed to AVIF Shares attributable to Glenbrook's assets held
in each Account), or (ii) prevent Participants from allocating payments to or
transferring amounts from a Fund that was otherwise available under the
Policies, until six (6) months after Glenbrook shall have notified AVIF of its
intention to do so and until 36 full calendar months shall have expired from the
date on which an Account first invested in any Fund.


      6.4     SURVIVAL OF WARRANTIES AND INDEMNIFICATIONS.

      All warranties and indemnifications will survive the termination of this
Agreement.


      6.5     CONTINUANCE OF AGREEMENT FOR CERTAIN PURPOSES.

      If any Party terminates this Agreement with respect to any Fund pursuant
to Sections 6.1(b), 6.1(c), 6.1(d), 6.1(f), 6.1(g), 6.1(h) or 6.1(i) hereof,
this Agreement shall nevertheless continue in effect as to any Shares of that
Fund that are outstanding as of the date of such termination (the "Initial
Termination Date").  This continuation shall extend to the earlier of the date
as of which an Account owns no Shares of the affected Fund or a date (the "Final
Termination Date") six (6) months following the Initial Termination Date, except
that Glenbrook may, by written notice shorten said six (6) month period in the
case of a termination pursuant to Sections 6.1(d), 6.1(f), 6.1(g), 6.1(h) or
6.1(i).



               SECTION 7.  PARTIES TO COOPERATE RESPECTING TERMINATION


      The Parties hereto agree to cooperate and give reasonable assistance to
one another in taking all necessary and appropriate steps for the purpose of
ensuring that an Account owns no Shares of a Fund after the Final Termination
Date with respect thereto, or, in the case of a termination pursuant to Section
6.1(a), the termination date specified in the notice of termination.  Such steps
may include combining the affected Account with another Account, substituting
other mutual fund shares for those of the affected Fund, or otherwise
terminating participation by the Policies in such Fund.



                                SECTION 8.  ASSIGNMENT

                            SECTION 10.  VOTING PROCEDURES


      Subject to the cost allocation procedures established pursuant to Section
3.1 hereof, Glenbrook will distribute all proxy material furnished by AVIF to
Participants to whom pass-through voting privileges are required to be extended
and will solicit voting instructions from Participants.  Glenbrook will vote
Shares in accordance with timely instructions received from Participants.
Glenbrook will vote Shares that are (a) not attributable to Participants to whom
pass-through voting privileges are extended,  or (b) attributable to
Participants, but for which no timely instructions have been received, in the
same proportion as Shares for which said instructions have been received from
Participants.  Neither Glenbrook nor any of its affiliates will in any way
recommend action in connection with or oppose or interfere with the solicitation
of proxies for the Shares held for such Participants,  except with respect to
matters as to which Glenbrook has the right, under Rule 6e-2 or 6e-3(T) under
the 1940 Act, to vote the Shares without regard to voting instructions from
Participants.  Glenbrook reserves the right to vote shares held in any Account
in its own right, to the extent permitted by law.  Glenbrook shall be
responsible for assuring that each of its Accounts holding Shares calculates
voting privileges in a manner consistent with that of other Participating
Insurance Companies or in the manner required by any Mixed and Shared Funding
exemptive order that AVIF may obtain in the future.  AVIF will notify Glenbrook
(i) of any changes of interpretations or amendments to any Mixed and Shared
Funding exemptive order it obtains in the future and (ii) of any proposal to be
submitted to Participants for their approval (prior to any Board of Directors
meeting of AVIF at which such proposals are presented).



                           SECTION 11.  FOREIGN TAX CREDITS


      AVIF agrees to consult in advance with Glenbrook concerning any decision
to elect or not to elect pursuant to Section 853 of the Code to pass through the
benefit of any foreign tax credits to its shareholders.





                             SECTION 12.  INDEMNIFICATION


      12.1    OF AVIF AND AIM BY GLENBROOK AND THE UNDERWRITER.

<PAGE>

   

      (a)     Except to the extent provided in Sections 12.1(b) and 12.1(c),
below, Glenbrook and the Underwriter each agrees to indemnify and hold harmless
AVIF, its affiliates (including AIM) except Participants, and each of their
respective directors and officers, and each person, if any, who controls AVIF or
its affiliates (including AIM)  within the meaning of Section 15 of the 1933 Act
(collectively, the "Indemnified Parties" for purposes of this Section 12.1)
against any and all losses, claims, damages, liabilities (including amounts paid
in settlement with the written consent of Glenbrook) or actions in respect
thereof (including, to the extent reasonable, legal and other expenses), to
which the Indemnified Parties may become subject under any statute, regulation,
at common law or otherwise, insofar as such losses, claims, damages, liabilities
or actions are related to the sale or acquisition of AVIF's Shares and:

      (i)     arise out of or are based upon any untrue statement or alleged
              untrue statement of any material fact contained in any Account's
              1933 Act registration statement, any Account Prospectus, the
              Policies, or sales literature or advertising for the Policies (or
              any amendment or supplement to any of the foregoing), or arise
              out of or are based upon the omission or the alleged omission to
              state therein a material fact required to be stated therein or
              necessary to make the statements therein not misleading;
              PROVIDED, that this agreement to indemnify shall not apply as to
              any Indemnified Party if such statement or omission or such
              alleged statement or omission was made in reliance upon and in
              conformity with information furnished to Glenbrook or the
              Underwriter by or on behalf of AVIF for use in any Account's 1933
              Act registration statement, any Account Prospectus, the Policies,
              or sales literature or advertising or otherwise for use in
              connection with the sale of Policies or Shares (or any amendment
              or supplement to any of the foregoing); or

      (ii)    arise out of or as a result of any other statements or
              representations (other than statements or representations
              contained in AVIF's 1933 Act registration statement, AVIF
              Prospectus, sales literature or advertising of AVIF, or any
              amendment or supplement to any of the foregoing, not supplied for
              use therein by or on behalf of Glenbrook or the Underwriter and
              on which such persons have reasonably relied) or the negligent,
              illegal or fraudulent conduct of Glenbrook, the Underwriter or
              their respective affiliates or persons under their control
              (including, without limitation, their employees and "Associated
              Persons," as that term is defined in paragraph (m) of Article I
              of the NASD's By-Laws), in connection with the sale or
              distribution of the Policies or Shares; or

      (iii)   arise out of or are based upon any untrue statement or alleged
              untrue statement of any material fact contained in AVIF's 1933
              Act registration statement, AVIF Prospectus, sales literature or
              advertising of AVIF, or any amendment or supplement to any of the
              foregoing, or the omission or alleged omission to state therein a
              material fact required to be stated therein or necessary to make
              the statements therein not misleading if such a statement or
              omission was made in reliance upon and in


                                          21

    

<PAGE>

   

              conformity with information furnished to AVIF or AIM by or on
              behalf of Glenbrook, the Underwriter or their respective
              affiliates for use in AVIF's 1933 Act registration statement,
              AVIF Prospectus, sales literature or advertising of AVIF, or any
              amendment or supplement to any of the foregoing; or

      (iv)    arise as a result of any failure by Glenbrook or the Underwriter
              to perform the obligations, provide the services and furnish the
              materials required of them under the terms of this Agreement, or
              any material breach of any representation and/or warranty made by
              Glenbrook or the Underwriter in this Agreement or arise out of or
              result from any other material breach of this Agreement by
              Glenbrook or the Underwriter; or

      (v)     arise as a result of failure by the Policies issued by Glenbrook
              to qualify as life insurance, endowment, or annuity contracts
              under the Code, otherwise than by reason of any Fund's failure to
              comply with Subchapter M or Section 817(h) of the Code.

      (b)     Neither Glenbrook nor the Underwriter shall be liable under this
Section 12.1 with respect to any losses, claims, damages, liabilities or actions
to which an Indemnified Party would otherwise be subject by reason of willful
misfeasance, bad faith, or gross negligence in the performance by that
Indemnified Party of its duties or by reason of that Indemnified Party's
reckless disregard of obligations or duties (i) under this Agreement or (ii) to
AVIF.

      (c)     Neither Glenbrook nor the Underwriter shall be liable under this
Section 12.1 with respect to any action against an Indemnified Party unless AVIF
or AIM shall have notified Glenbrook or the Underwriter in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the action shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify Glenbrook or the
Underwriter of any such action shall not relieve Glenbrook or the Underwriter
from any liability which it may have to the Indemnified Party against whom such
action is brought otherwise than on account of this Section 12.1.  Except as
otherwise provided herein, in case any such action is brought against an
Indemnified Party, Glenbrook or the Underwriter shall be entitled to
participate, at its own expense, in the defense of such action and  Glenbrook or
the Underwriter also shall be entitled to assume the defense thereof, with
counsel approved by the Indemnified Party named in the action, which approval
shall not be unreasonably withheld.  After notice from Glenbrook or the
Underwriter to such Indemnified Party of its election to assume the defense
thereof, the Indemnified Party will cooperate fully with Glenbrook and shall
bear the fees and expenses of any additional counsel retained by it, and
Glenbrook  will not be liable to such Indemnified Party under this Agreement for
any legal or other expenses subsequently incurred by such Indemnified Party
independently in connection with the defense thereof, other than reasonable
costs of investigation.

      (a)     Except to the extent provided in Sections 12.2(d), 12.2(e) and
12.2(f), below,  to the extent  permitted by law,  AVIF and/or AIM each agrees
to indemnify and hold harmless Glenbrook, the Underwriter, their respective
affiliates, and each of their respective directors and officers, and each
person, if any, who controls Glenbrook, the Underwriter, or their respective
affiliates within the meaning of Section 15 of the 1933 Act (collectively, the
"Indemnified Parties" for purposes of this Section 12.2) against any and all
losses, claims, damages, liabilities (including amounts paid in settlement with
the written consent of AVIF and/or AIM) or actions in respect thereof
(including, to the extent reasonable, legal and other expenses), to which the
Indemnified Parties may become subject under any statute, regulation, at common
law, or otherwise, insofar as such losses, claims, damages, liabilities or
actions are related to the sale or acquisition of AVIF's Shares and:

      (i)     arise out of or are based upon any untrue statement or alleged
              untrue statement of any material fact contained in AVIF's 1933
              Act registration statement, AVIF Prospectus or sales literature
              or advertising of AVIF (or any amendment or supplement to any of
              the foregoing), or arise out of or are based upon the omission or
              the alleged omission to state therein a material fact required to
              be stated therein or necessary to make the statements therein not
              misleading; PROVIDED, that this agreement to indemnify shall not
              apply as to any Indemnified Party if such statement or omission
              or such alleged statement or omission was made in reliance upon
              and in conformity with information furnished to AVIF or its
              affiliates by or on behalf of Glenbrook or its affiliates for use
              in AVIF's 1933 Act registration statement, AVIF Prospectus, or in
              sales literature or advertising (or any amendment or supplement
              to any of the foregoing); or

      (ii)    arise out of or as a result of any other statements or
              representations (other than statements or representations
              contained in any Account's 1933 Act registration statement, any
              Account Prospectus, sales literature or advertising for the
              Policies, or any amendment or supplement to any of the foregoing,

              affiliates or persons under their control (including, without
              limitation, their employees and "Associated Persons"), in
              connection with the sale or distribution of AVIF Shares; or

      (iii)   arise out of or are based upon any untrue statement or alleged
              untrue statement of any material fact contained in any Account's
              1933 Act registration statement, any Account Prospectus, sales
              literature or advertising covering the Policies, or any amendment
              or supplement to any of the foregoing, or the omission or alleged
              omission to state therein a material fact required to be stated
              therein or necessary to make the statements therein not
              misleading, if such statement or omission was made in reliance
              upon and in conformity with information furnished to Glenbrook,

              Policies, or any amendment or supplement to any of the foregoing;

              result from any other material breach of this Agreement by AVIF
              or AIM.

      (b)     Except to the extent provided in Sections 12.2(c), 12.2(d) and
12.2(e) hereof, AVIF agrees to indemnify and hold harmless the Indemnified
Parties from and against any and all losses, claims, damages, liabilities
(including amounts paid in settlement thereof with,  the written consent of
AVIF) or actions in respect thereof (including, to the extent reasonable, legal
and other expenses) to which the Indemnified Parties may become subject directly
or indirectly under any statute, at common law or otherwise, insofar as such
losses, claims, damages, liabilities or actions directly or indirectly result
from or arise out of the failure of any Fund to operate as a regulated
investment company in compliance with (i) Subchapter M of the Code and
regulations thereunder or (ii) Section 817(h) of the Code and regulations
thereunder, including, without limitation, any income taxes and related
penalties, rescission charges, liability under state law to Participants
asserting liability against Glenbrook or the Underwriter pursuant to the
Policies, the costs of any ruling and closing agreement or other settlement with
the IRS, and the cost of any substitution by Glenbrook of Shares of another
investment company or portfolio for those of any adversely affected Fund as a
funding medium for each Account that Glenbrook reasonably deems necessary or
appropriate as a result of the noncompliance.

      (c)     AVIF shall not be liable under this Section 12.2 with respect to
any losses, claims, damages, liabilities or actions to which an Indemnified
Party would otherwise be subject by reason of willful misfeasance, bad faith, or
gross negligence in the performance by that Indemnified Party of its duties or
by reason of such Indemnified Party's reckless disregard of its obligations and
duties (i) under this Agreement or (ii) to Glenbrook, each Account, the
Underwriter or Participants.

      (d)     AVIF shall not be liable under this Section 12.2 with respect to
any action against an Indemnified Party unless the Indemnified Party shall have
notified AVIF in writing within a reasonable time after the summons or other
first legal process giving information of the nature of the action shall have
been served upon such Indemnified Party (or after such Indemnified Party shall
have received notice of such service on any designated agent), but failure to
notify AVIF of any such action shall not relieve AVIF from any liability which
it may have to the Indemnified Party against whom such action is brought
otherwise than on account of this Section 12.2.  Except as otherwise provided
herein, in case any such action is brought against an Indemnified Party, AVIF
will be


                                          24

entitled to participate, at its own expense, in the defense of such action and
also shall be entitled to assume the defense thereof, with counsel approved by
the Indemnified Party named in the action, which approval shall not be
unreasonably withheld.  After notice from AVIF to such Indemnified Party of
AVIF's election to assume the defense thereof, the Indemnified Party will
cooperate fully with AVIF and shall bear the fees and expenses of any additional
counsel retained by it, and AVIF will not be liable to such Indemnified Party
under this Agreement for any legal or other expenses subsequently incurred by
such Indemnified Party independently in connection with the defense thereof,
other than reasonable costs of investigation.

      (e)  In no event shall AVIF be liable under the indemnification
provisions contained in this Agreement to any individual or entity, including
without limitation, Glenbrook, the Underwriter, or any other Participating
Insurance Company or any Participant, with respect to any losses, claims,
damages, liabilities or expenses that arise out of or result from (i) a breach
of any representation, warranty, and/or covenant made by Glenbrook or the
Underwriter hereunder or by any Participating Insurance Company under an
agreement containing substantially similar representations, warranties and
covenants; (ii) the failure by Glenbrook or any Participating Insurance Company
to maintain its segregated asset account (which invests in any Fund) as a
legally and validly established segregated asset account under applicable state
law and as a duly registered unit investment trust under the provisions of the
1940 Act (unless exempt therefrom); or (iii) the failure by Glenbrook or any
Participating Insurance Company to maintain its variable annuity and/or variable
life insurance contracts (with respect to which any Fund serves as an underlying
funding vehicle) as life insurance, endowment or annuity contracts under
applicable provisions of the Code; provided, however, that the limitation of
liability contained in this paragraph (e) shall not apply if the breach or
failures described in subparagraphs (i), (ii) and (iii), above, by Glenbrook or
any Participating Insurance Company resulted from the failure of AVIF to comply
with the requirements of Subchapter M or Section 817(h) of the Code.


      12.3    EFFECT OF NOTICE.

      Any notice given by the indemnifying Party to an Indemnified Party
referred to in Section 12.1(c) or 12.2(d) above of participation in or control
of any action by the Indemnifying Party will in no event be deemed to be an
admission by the Indemnifying Party of liability, culpability or responsibility,
and the Indemnifying Party will remain free to contest liability with respect to
the claim among the Parties or otherwise.


      12.4    SUCCESSORS.

      A successor by law of any Party shall be entitled to the benefits of the
indemnification contained in this Section 12.

                             AIM'S PRICING ERROR POLICIES


DETERMINATION OF MATERIALITY

In the event that AIM discovers an error in the calculation of the Fund's net
asset value, the following policies will apply:

If the amount of the error is less than $.01 per share, it is considered
immaterial and no adjustments are made.

If the amount of the error is $.01 per share or more, then the following
thresholds are applied:

      a.  If the amount of the difference in the erroneous net asset value and
      the correct net asset value is less than .5% of the correct net asset
      value, AIM will reimburse the affected Fund to the extent of any loss
      resulting from the error.  No other adjustments shall be made.

      b.  If the amount of the difference in the erroneous net asset value and
      the correct net asset value is .5% of the correct net asset value or
      greater, then AIM will determine the impact of the error to the affected
      Fund and shall reimburse such Fund (and/or Glenbrook, as appropriate) to
      the extent of any loss resulting from the error.  To the extent that an
      overstatement of net asset value per share is detected quickly and
      Glenbrook has not mailed redemption checks to Participants, Glenbrook and
      AIM agree to examine the extent of the error to determine the feasibility
      of reprocessing such redemption transaction (for purposes of reimbursing
      the Fund to the extent of any such overpayment).

REPROCESSING COST REIMBURSEMENT

To the extent a reprocessing of Participant transactions is required pursuant to
paragraph (b), above, AIM shall reimburse Glenbrook for Glenbrook's reprocessing
costs in the amount of $3.00  per contract affected by $10 or more.

The Pricing Policies described herein may be modified by AVIF as approved by its
Board of Directors.  AIM agrees to use its best efforts to notify Glenbrook at
least five days prior to any such meeting of the Board of Directors of AVIF to
consider such proposed changes.
