This Prospectus  describes the group and individual  Flexible  Premium  Deferred

("Company"),  a wholly owned subsidiary of Allstate Life Insurance Company. Dean

particular  needs.  It is  designed  to aid you in your  choice  of  short-term,
mid-term,  or  long-term  financial  planning  and  can be used  for  retirement
planning regardless of whether the plan qualifies for special federal income tax
treatment.  Presently,  the Company will accept  Purchase  Payments of $1,000 or
more which may be added to the Contract.

Partial withdrawals and Surrenders under the Contract may be subject to a Market
Value  Adjustment.  Therefore,  the Owner bears some  investment  risk under the

INTRODUCTION
1. WHAT IS THE PURPOSE OF THE CONTRACT?

   
The Contract described in this Prospectus provides a cash withdrawal benefit and
a Death  Benefit  during the  Accumulation  Phase and periodic  Income  Payments
beginning  on the Payout  Start Date  during the Payout  Phase.  (See,  "Partial
Withdrawals  and  Surrenders,"  pg. 7, "Death  Benefits," pg. 9, and "The Payout
Phase," pg. 9.)

The cash  withdrawal  benefit may be subject to a Market  Value  Adjustment.  As
such, the Owner bears some  investment  risk under the Contract.  (See,  "Market
Value Adjustment," pg. 8.)
    

2. HOW DO I PURCHASE A CONTRACT?

The Company has discontinued the offering of new contracts.  Additional Purchase
Payments to existing Contracts are accepted by the Company.

   
At the time of purchase, you select the Guarantee Period(s) in which to allocate
your Purchase Payment.  Guarantee Periods,  which are offered at our discretion,
may range from one to ten years. No less than $1,000 may be allocated to any one
Guarantee Period. You may participate in the Automatic  Laddering Program at the
time of purchase.  The Automatic  Laddering  Program allows you to choose future
renewal Guarantee Periods. (See, "Purchase of the Contract," pg. 6.)
    

3. CAN I MAKE SUBSEQUENT PURCHASE PAYMENTS TO THIS CONTRACT?

   
Purchase  Payments may be made at any time during the Accumulation  Phase of the
Contract.  Subsequent  Purchase  Payments  must be at least  $1,000.  Additional
Purchase  Payments  may also be made from your bank  account or your Dean Witter
Active Assets(TM) Account through Automatic Additions. For each Purchase Payment
you will select a Guarantee  Period(s)  to which the  Purchase  Payment  will be
allocated. (See, "Purchase of the Contract," pg. 6.)
    

4. WHAT IS A GUARANTEE PERIOD AND WHAT HAPPENS AT THE END OF IT?

   
Interest is credited,  at an effective annual rate declared by the Company,  for
the  Guarantee  Period.  At the end of the  Guarantee  Period,  you can select a
renewal Guarantee  Period(s),  or the selection of a renewal Guarantee Period(s)
can be made through the  Automatic  Laddering  Program.  If the Company does not
receive a selection by the end of the Guarantee  Period,  a Guarantee  Period of
the same duration as the previous one will  automatically  be established.  If a
different  selection  is made  within  10  calendar  days  after  the end of the
Guarantee  Period,  the Sub-Account  automatically set will be changed as of the
end of the  Guarantee  Period  just  expired  to  match  this  selection.  (See,
"Subsequent Guarantee Periods," pg. 6.)
    

5. IS THERE A FREE-LOOK PROVISION?

The Owner may cancel the  Contract  anytime  within 20 days after the receipt of
the Contract and receive a full refund of Purchase Payments.

6. DOES THE CONTRACT HAVE CHARGES OR DEDUCTIONS?

There are no front-end  charges under the Contract.  A Withdrawal Charge will be
applied to a partial  withdrawal  or Surrender.  Withdrawal  Charges will be the
lesser of (a) one-half  the  effective  annual  interest  rate  credited for the
Sub-Account  multiplied by the amount withdrawn in excess of the Free Withdrawal
Amount;  or (b)  interest  earned  at  the  time  of  withdrawal  on the  amount
withdrawn. If money is withdrawn from the

   
Sub-Account  prior to the end of its Guarantee Period, a Market Value Adjustment
will be made to the money  distributed in excess of the Free Withdrawal  Amount.
The Market  Value  Adjustment  may be positive or  negative.  (See,  "Withdrawal
Charge," pg. 8, and "Market Value Adjustment," pg. 8.)
    

Money may be withdrawn from a Sub-Account  during the 10 calendar days after the
end of the  Guarantee  Period  without  incurring a  Withdrawal  Charge or being
subject to a Market Value Adjustment.  If a surrender request is received by the
Company  at its  home  office  within  10  calendar  days  after  the end of the
Guarantee  Period,  funds  will be  liquidated  as of the  end of the  Guarantee
Period.

7. CAN I GET MY MONEY IF I NEED IT?

   
All or part of the Account  Value can be  withdrawn  before the  earliest of the
Payout  Start  Date,  the death of the  Owner,  or the  death of the  Annuitant.
Withdrawal Charges,  taxes, tax penalties,  and a Market Value Adjustment may be
applied to the partial withdrawal or Surrender.  (See, "Partial  Withdrawals and
Surrenders," pg. 7.)
    

THE COMPANY  GUARANTEES THAT IF YOU SURRENDER THE CONTRACT,  YOU WILL RECEIVE AN
AMOUNT  AT  LEAST  EQUAL  TO  ALL  PURCHASE  PAYMENTS  LESS  ANY  PRIOR  PARTIAL
WITHDRAWALS.

8. DOES THE CONTRACT HAVE A GUARANTEED DEATH BENEFIT?

   
Prior to the Payout  Start Date,  the Contract  offers a Death  Benefit upon the
death of the Owner or Annuitant,  whichever  occurs first.  The Death Benefit is
the greater of the Account Value or the Settlement  Value as of the receipt of a
complete request for payment of the Death Benefit.  (See,  "Death Benefits," pg.
9.)
    

Death Benefits after the Payout Start Date depend on the income plan chosen.

9. WHAT HAPPENS IN THE PAYOUT PHASE OF THE CONTRACT?

   
During this phase,  the Account Value less premium tax and any other  applicable
tax is  applied  to the  income  plan you choose and monies are paid to you on a
scheduled  basis as provided in that plan. The Payout Phase begins on the Payout
Start Date. It continues until the Company makes the last payment as provided by
the income plan chosen. (See, "The Payout Phase," pg. 9.)
    


THE CONTRACTS
PURCHASE OF THE CONTRACT

The Company will apply  Purchase  Payments to the Contract  within seven days of
the  receipt of the  Purchase  Payment and  required  issuing  information.  The
Company reserves the right to limit or increase the amount of Purchase  Payments
it will accept.

The Company has discontinued the offering of new Contracts.  Additional Purchase
Payments to existing Contracts are accepted by the Company.

Subsequent  Purchase  Payments  may be made at any time during the  Accumulation
Phase of the  Contract.  Subsequent  Purchase  Payments must be at least $1,000.
Additional  Purchase  Payments  may also be made from your bank  account or your
Dean Witter Active Assets(TM) Account through Automatic Additions. The Automatic
Additions Program is not available for Qualified  Contracts issued pursuant to a
Dean Witter Custodial Account.

The  Contract  described  in this  prospectus  is made up of two  phases  -- the
Accumulation Phase and the Payout Phase.


THE ACCUMULATION PHASE
THE ACCUMULATION PHASE DEFINED

The  Accumulation  Phase begins on the Issue Date and continues until the Payout
Start Date. During this phase, cash withdrawal  benefits and a Death Benefit are
available. Interest will be credited to initial Purchase Payments from the Issue
Date. Interest will be credited to subsequent Purchase Payments from the date of
receipt.  No deductions  are made from Purchase  Payments.  Therefore,  the full
amount of each Purchase Payment is invested in a Sub-Account for accumulation of
interest.  At least once every  Contract year, the Company will send the Owner a
statement containing Account Value information.

SUBSEQUENT GUARANTEE PERIODS

For each subsequent  Purchase  Payment,  the Owner will be required to designate
Guarantee  Period(s) in which to allocate funds.  Guarantee  Periods,  which are
offered at the Company's  discretion,  may range from one to ten years.  No less
than $1,000 may be allocated to any one Guarantee  Period at the time a Purchase
Payment is made or a renewal Guarantee Period is selected.

A notice will be mailed 21 calendar days prior to the expiry of each Sub-Account
directing  you to select a renewal  Guarantee  Period(s) or reminding you of the
choice you made through the Automatic Laddering Program. If the Company does not
receive a selection by the end of the Guarantee  Period,  a Guarantee  Period of
the same duration as the previous one will  automatically  be established.  If a
renewal Guarantee Period selection is made within 10 calendar days after the end
of the Guarantee Period, a Sub-Account(s)  will be established as of the renewal
date, in accordance with that selection.

INTEREST CREDITED

Interest  will be credited  daily based on the  effective  annual  interest rate
declared by us at that time for that  particular  Guarantee  Period.  "Effective
annual rate" means the yield  earned when  interest  credited at the  underlying
daily rate has compounded for a full year.  Effective annual interest rates will
be declared  periodically  for each  Guarantee  Period then being  offered.  The
declared rates will be greater than or equal to the minimum guaranteed  interest
rate  under the  Contract.  The  "minimum  guaranteed  interest  rate  under the
Contract" is a rate of interest specified in the Contract that is guaranteed for
the life of 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  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.

Set forth below is an illustration of how interest will be credited to the funds
in your Sub-Account during the Guarantee Period.

NOTE: The following illustration assumes no withdrawals of any amount during the
entire five year period. A Market Value  Adjustment and Withdrawal  Charge would
apply to any such interim  withdrawal in excess of the Free  Withdrawal  Amount.
The hypothetical  interest rates are for illustrative  purposes only and are not
intended to predict  future  interest  rates to be declared  under the Contract.
Actual  interest  rates declared for any given  Guarantee  Period may be more or
less than those shown.

PARTIAL WITHDRAWALS AND SURRENDERS

You have the right to make a partial  withdrawal or Surrender at any time during
the Accumulation  Phase. You must specify the Sub-Account(s) from which you wish
to make a withdrawal.  A withdrawal amount free of Withdrawal Charges and Market
Value Adjustments will be available in each year for each Sub-Account.  The Free
Withdrawal Amount is 10% of the amount of the Sub-Account's  Purchase Payment or
funds initially  allocated to the  Sub-Account.  Any Free Withdrawal  Amount not
withdrawn  in a  Sub-Account  year may not be carried  over to increase the Free
Withdrawal  Amount  in  a  subsequent  Sub-Account  year.  Similarly,  the  Free
Withdrawal  Amount not withdrawn in one  Sub-Account  may not be  transferred to
increase the Free Withdrawal  Amount in another  Sub-Account.  Amounts withdrawn
from the  Sub-Account  will be adjusted  by any  applicable  Withdrawal  Charge,
Market Value Adjustment,  and taxes. The applicable Withdrawal Charge and Market
Value  Adjustment  will be  applied  to any  withdrawal  in  excess  of the Free
Withdrawal Amount.

The minimum partial  withdrawal is $100. If a partial  withdrawal  would leave a
Sub-Account  Value of less than $1,000,  then the Company will treat the request
as one  for a  withdrawal  of  the  Sub-Account's  entire  value.  If a  partial
withdrawal  reduces the Account  Value of the Contract to less than $1,000,  the
Company will treat the request as a withdrawal  of the entire  Account Value and
the Contract will terminate.

Partial  withdrawals  may  also  be  taken   automatically   through  Systematic
Withdrawals. Please consult with your Dean Witter Account Executive for detailed
information about Systematic Withdrawals.

   
Withdrawals  and  surrenders may be subject to income tax and a 10% tax penalty.
The tax and penalty are explained in "Federal Tax Matters" on page 10.
    

WITHDRAWAL CHARGE

A Withdrawal  Charge will be applied to a partial  withdrawal or Surrender  made
prior to the end of a  Guarantee  Period  and will be  deducted  from the amount
distributed. (See, "Appendix A".)

Withdrawal Charges will be the lesser of:

     a.   one-half  the  effective  annual  interest   crediting  rate  for  the
          Sub-Account  multiplied by the amount  withdrawn in excess of the Free
          Withdrawal Amount; or

     b.   interest earned on the amount withdrawn.

MARKET VALUE ADJUSTMENT

The  amount  payable  on a  partial  withdrawal  or full  surrender  made from a
Sub-Account prior to the end of any Guarantee Period may be adjusted up or down,
or not at all, by the  application  of the Market Value  Adjustment.  The Market
Value Adjustment factor is applied to the amount withdrawn in excess of the Free
Withdrawal  Amount.  The Market Value  Adjustment will reflect the  relationship
between the current effective annual interest rate for the duration remaining in
the Guarantee Period at the time of the request for withdrawal or surrender, and
the effective annual interest rate guaranteed for that Sub-Account.

Generally,  if the effective  annual interest rate for the Sub-Account is higher
than the applicable  current effective annual interest rate (interest rate for a
duration equal to the time remaining in the Sub-Account),  then the Market Value
Adjustment  will result in a higher payment upon  surrender.  Similarly,  if the
effective  annual interest rate for the Sub-Account is lower than the applicable
current  effective  annual interest rate, then the Market Value  Adjustment will
result in a lower payment upon surrender.

For example,  the Owner  purchases a Contract  and selects an initial  Guarantee
Period of five years and the Company's  effective  annual rate for that duration
is  4.50%.  Assume  that at the  end of 3  years,  the  Owner  makes  a  partial
withdrawal. If the current interest rate for a 2 year Guarantee Period is 4.20%,
then the Market  Value  Adjustment  will be  positive,  which will  result in an
increase  in the  amount  payable  to the  Owner  upon the  partial  withdrawal.
Similarly,  if the  current  interest  rate for the 2 year  Guarantee  Period is
4.80%, then the Market Value Adjustment will be negative, which will result in a
decrease in the amount payable to the Owner upon partial withdrawal.

Since  current  interest  rates  are  based,  in part,  upon  investment  yields
available at the time, the effect of the Market Value Adjustment will be closely
related to the levels of such yields. It is theoretically  possible,  therefore,
that,  should  such yields  increase  significantly  from the time the  Purchase
Payment was made,  coupled with the  application of the Withdrawal  Charge,  the
amount  received by the Owner upon full  surrender of the Contract would be less
than the Purchase Payment plus interest at the minimum guaranteed  interest rate
under the Contract.  HOWEVER,  THE COMPANY  GUARANTEES  THAT THE AMOUNT RECEIVED
UPON  SURRENDER  WILL BE AT LEAST EQUAL TO THE PURCHASE  PAYMENTS LESS ANY PRIOR
PARTIAL  WITHDRAWALS.  The renewal of any individual  Sub-Account(s)  within the
entire  Contract  does not in any way  change  the  return of  Purchase  Payment
guarantee  provided by this  Contract.  Upon  Sub-Account  renewal the return of
Purchase Payment guarantee will not be adjusted to include any accrued interest,
but will continue to apply to the initial and any subsequent Purchase Payments.

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.

WITHDRAWALS AT THE END OF THE GUARANTEE PERIOD

During the first 10 days of a renewal  Guarantee  Period,  any amount  withdrawn
will not  incur a  Withdrawal  Charge or Market  Value  Adjustment,  nor will it
reflect any interest earned during this 10-day period.

TAXES

A premium tax deduction will be made, if provided under  applicable law, on full
surrender,  or upon  annuitization  of the Contract.  Current  premium tax rates
range from 0 to 3.5%, but are subject to change by state  regulation.  Any other
applicable taxes will be deducted as well.

PAYMENT UPON PARTIAL WITHDRAWAL OR SURRENDER

The  Company may defer  payment of any partial  withdrawal  or  surrender  for a
period not exceeding six months from the date of the receipt of the request.

DEATH BENEFITS

If any Owner or Annuitant  dies prior to the Payout Start Date, a Death  Benefit
may be paid.

If an Owner dies prior to the Payout  Start Date,  the new Owner (any  surviving
Owner(s), and if none, the Beneficiary) may elect, within 60 days of the Date of
Death,  to receive the Death Benefit in a lump sum or apply the Death Benefit to
an income plan.  The Company is  currently  waiving the 60 day  limitation.  The
Company  reserves the right to enforce the  limitation  in the future.  Payments
from the income plan must begin within one year of the Date of Death and must be
over the life of the new Owner, or a period not to exceed the life expectancy of
the new  Owner.  Otherwise,  the new Owner may elect to receive  the  Settlement
Value  payable in a lump sum within 5 years of the Date of Death.  Any remaining
funds will be  distributed  at the end of the 5-year  period.  An  Annuitant  is
necessary to continue the Contract between the date of the Owner's death and the
final  distributions.  If there is no Annuitant at that time,  the new Annuitant
will be the youngest new Owner.

If the new Owner is the surviving spouse of the deceased Owner,  then the spouse
may  continue  the  Contract in the  Accumulation  Phase as if the death had not
occurred.  If there is no Annuitant at that time,  the new Annuitant will be the
surviving spouse. The surviving spouse may also select one of the options listed
above.

If the new Owner is a non-natural person (other than a grantor trust),  then the
Owner must receive the Death Benefit in a lump sum, and the options listed above
are not available.

If the Annuitant,  not also an Owner, dies prior to the Payout Start Date, then,
in most cases, the Owner has the following three options:

     -    continue  the  Contract  as if the  death  had not  occurred.  The new
          Annuitant  will  be the  youngest  Owner  unless  the  Owner  names  a
          different Annuitant; or

     -    receive the Death Benefit in a lump sum. The Death Benefit is equal to
          the greater of the Account Value or the Cash Surrender Value, or

     -    apply the Death Benefit to an Income Plan.


THE PAYOUT PHASE
The Payout  Phase is the second of the two  phases in the  Contract.  The Payout
Phase begins on the Payout Start Date and continues  until the Company makes the
last payment as provided by the income plan.

Unless the Owner notifies the Company in writing,  the Payout Start Date will be
the later of the Annuitant's  90th birthday or the 10th  anniversary date of the
Contract.

The Owner may change the Payout Start Date at any time by notifying  the Company
in writing of the change at least 30 days before the current  Payout Start Date.
The Payout Start Date must be no later than the Annuitant's 90th birthday or the
10th  anniversary  date of the  Contract,  if later.  The  Owner of a  Qualified
Contract  may be limited by the plan under  which the  Contract  is issued  with
regard to a Payout Start Date after age 70 1/2.

INCOME PLANS

The Owner may  elect an income  plan  which  distributes  Income  Payments  on a
scheduled  basis.  Up to 30 days  before the Payout  Start  Date,  the Owner may
change the income  plan or request any other form of income  plan  agreeable  to
both the Company and the Owner. If the Company does not receive a written choice
from the Owner,  the income plan will be life  income with 120 monthly  payments
guaranteed.  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. If
the sole surviving Owner dies after the Payout Start Date, the Beneficiary  will
receive any guaranteed Income Payments scheduled to continue.

The Account  Value on the Payout Start Date,  less any  applicable  tax, will be
applied to the income plan selected by the Owner. The income plans include:

  INCOME PLAN 1--Life Income with Guaranteed Payments

  Payments will be made to the Owner for as long as the Annuitant  lives. If the
  Annuitant  dies  before  all the  guaranteed  payments  have  been  made,  the
  remainder of the guaranteed payments will be paid to the Owner.

  INCOME PLAN 2--Joint and Survivor Life Income with Guaranteed Payments

  Payments  beginning  on the Payout Start Date will be made to the Owner for as
  long as  either  the  Annuitant  or Joint  Annuitant  is  living.  If both the
  Annuitant and Joint Annuitant die before all the guaranteed payments have been
  made, the remainder of the guaranteed payments will be made to the Owner.

  INCOME PLAN 3--Guaranteed Payments for a Specified Period

  Payments  beginning  on the Payout  Start Date will be made to the Owner for a
  specified period. Payments under this option do not depend on the continuation
  of the  Annuitant's  life.  The number of  guaranteed  months may be 60 to 360
  months.

At the Company's discretion, other income plans may be available.

PAYOUT TERMS

The  Contracts  described in this  prospectus  (except in states  which  require
unisex  annuity  tables)  contain life annuity tables that provide for different
benefit payments to men and women of the same age.  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  may be  used.  Accordingly,  if the  Contract  is to be  used  in
connection with an employment-related  retirement or benefit plan, consideration
should be given, in consultation with legal counsel,  to the impact of Norris on
any such plan before making any contributions under these Con- tracts.

The duration of the income plan will generally affect the dollar amounts of each
Income  Payment.  For example,  if an income plan guaranteed for life is chosen,
the Income  Payments  may be greater or lesser  than  Income  Payments  under an
income plan for a  specified  period  depending  on the life  expectancy  of the
Annuitant.

After the Account  Value has been  applied to an income plan on the Payout Start
Date,  the income  plan cannot be changed and no  withdrawals  can be made.  The
Company may require proof that the  Annuitant or Joint  Annuitant is still alive
before the Company makes each payment that depends on their continued life.

If any Owner dies during the Payout  Phase,  Income  Payments  will  continue as
scheduled, in accordance with the income plan in effect.

If the Account Value to be applied to an income plan is less than $2,000,  or if
the monthly Income Payments  determined under the income plan are less than $20,
the  Company  may pay the  Account  Value in a lump sum or  change  the  payment
frequency to an interval which results in Income Payments of at least $20.

AMENDMENT OF THE CONTRACTS
The Company  reserves the right to amend the Contracts to meet the  requirements
of applicable federal or state laws or regulations.  The Company will notify the
Owner of any such amendments.

DISTRIBUTION OF THE CONTRACTS
The Contracts  will be distributed  exclusively by Dean Witter,  which serves as
the principal underwriter of the Contracts under a General Agency Agreement with
the Company.  Dean Witter is a wholly owned  subsidiary  of Morgan  Stanley Dean
Witter & Co.

The Company may pay up to a maximum sales commission of 8% both upon sale of the
Contract and upon renewal of a Guarantee Period.

Dean Witter is located at Two World Trade  Center,  New York,  New York,  10048.
Dean  Witter  is a  member  of the New  York  Stock  Exchange  and the  National
Association of Securities Dealers, Inc.

The General Agency  Agreement  between the Company and Dean Witter provides that
the Company will indemnify Dean Witter for certain damages that may be caused by
actions, statements or omissions by the Company.

CUSTOMER INQUIRIES
The Owner or any persons interested in the Contract may make inquiries regarding
the Contract by calling or writing their Dean Witter Account Executive.

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 THE COMPANY

The Company is taxed as a life insurance company under Part I of Subchapter L of
the Internal Revenue Code. The following  discussion assumes that the Company is
taxed as a life insurance company under Part I of Subchapter L.

TAXATION OF ANNUITIES IN GENERAL

TAX DEFERRAL

In  general,  an  annuity  contract  owned by a  natural  person is not taxed on
increases in the contract value until a distribution  occurs.  Annuity contracts
owned by non-natural  persons are generally 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 exceptions to the  non-natural  owner rule and you should discuss these with
your tax advisor.

DELAYED MATURITY DATE

If the  contract's  scheduled  maturity date is at a time when the annuitant has
reached an advanced age, it is possible  that the contract  would not be treated
as an annuity.  In that event,  the income and gains under the contract would 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,  without  regard to any
surrender charges, exceeds the investment in the contract. The contract value is
the sum of all sub-account  values.  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 gross  income.  No matter which  sub-account a withdrawal is made
from, all subaccount values are combined and the total contract value is used to
determine  the amount of  taxable  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  bears to the contract
value, can be excluded from income. No definitive  guidance exists on the proper
tax treatment of Market Value Adjustments and you should contact a competent tax
advisor  with  respect  to the  potential  tax  consequences  of a Market  Value
Adjustment. 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.

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 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 this
ratio, the annuity payments are 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 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 date the owner attains age 59 1/2. However, there
should be no penalty tax on  distributions  to owners:  (1) made on or after the
date 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;  or (4) made under an  immediate  annuity.  Similar  rules apply for
distributions  from  qualified  contracts.  Consult a competent  tax advisor for
other possible exceptions to the penalty tax.

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.

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
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 nonnatural person, then the annuitant will be treated as the owner
for purposes of applying  the  distribution  at death  rules.  Also, a change of
annuitant  on a contract  owned by a  nonnatural  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.

ROTH INDIVIDUAL RETIREMENT ANNUITIES

Section  408A of the Code permits  eligible  individuals  to make  nondeductible
contributions  to an individual  retirement  program known as a Roth  Individual
Retirement  Annuity.   Roth  Individual  Retirement  Annuities  are  subject  to
limitations  on the  amount  that  can be  contributed  and  on  the  time  when
distributions  may  commence.  "Qualified  distributions"  from Roth  Individual
Retirement   Annuities  are  not   includible   in  gross   income.   "Qualified
distributions" are any distributions made more than five taxable years after the
taxable  year  of the  first  contribution  to the  Roth  Individual  Retirement
Annuity,  and which are made on or after the date the individual  attains age 59
1/2 , made to a beneficiary  after the owner's death,  attributable to the owner
being disabled or for a first time home purchase  (first time home purchases are
subject  to a  lifetime  limit of  $10,000).  "Nonqualified  distributions"  are
treated as made from  contributions  first and are includible in gross income to
the  extent  such  distributions  exceed  the  contributions  made  to the  Roth
Individual   Retirement   Annuity.   The  taxable  portion  of  a  "nonqualified
distribution" may be subject to the 10% penalty tax on premature  distributions.
Subject to certain limitations,  a traditional  Individual Retirement Account or
Annuity  may be  converted  or  "rolled  over" to a Roth  Individual  Retirement
Annuity.  The  taxable  portion of a  conversion  or  rollover  distribution  is
includible  in  gross  income,  but is  exempted  from  the 10%  penalty  tax on
premature distributions.

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.

SAVINGS INCENTIVE MATCH PLANS FOR EMPLOYEES (SIMPLE PLANS)

Sections  408(p)  and  401(k)  of the  Code  allow  employers  with 100 or fewer
employees to establish SIMPLE retirement plans for their employees. SIMPLE plans
may be structured as a SIMPLE retirement account using an employee's  Individual
Retirement  Annuity to hold the assets or as a Section 401(k)  qualified cash or
deferred  arrangement.  In general,  a SIMPLE plan consists of a salary deferral
program for eligible  employees  and matching  contributions  made by employers.
Employers  intending to use the contract in conjunction with SIMPLE plans should
seek competent tax and legal advice.

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
on or after the date 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).

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  employees.  Such retirement plans may
permit the purchase of annuity  contracts in order to provide benefits under the
plans.

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. To the extent the  contracts are used in connection  with an
eligible plan,  employees are considered  general  creditors of the employer and
the  employer as owner of the contract has the sole right to the proceeds of the
contract.  Generally,  under the non-natural owner rules, such contracts are not
treated as annuity  contracts for federal  income tax purposes.  However,  under
these plans,  contributions  made for the benefit of the  employees  will not be
includible in the employees' gross income until distributed from the plan.

INCOME TAX WITHHOLDING

The Company is required to withhold  federal  income tax at a rate of 20% on all
"eligible rollover  distributions" unless an individual elects to make a "direct
rollover" of such amounts to another  qualified  plan or  Individual  Retirement
Account or Annuity (IRA). Eligible rollover distributions  generally include all
distributions  from qualified  contracts,  excluding IRAs, with the exception of
(1)  required  minimum  distributions,  or (2) a series of  substantially  equal
periodic  payments  made over a period of at least 10 years,  or the life (joint
lives)  of  the  participant  (and  beneficiary).  For  any  distributions  from
non-qualified annuity contracts, or distributions from qualified contracts which
are not considered eligible rollover distributions,  the Company may be required
to withhold  federal and state income taxes unless the  recipient  elects not to
have taxes withheld and properly notifies the Company of such election.

THE COMPANY
BUSINESS

Incorporated  in 1978 as a stock life  insurance  company  under the laws of the
State of Illinois, the Company has done business continuously since that time as
"Northbrook  Life  Insurance  Company." The Company  issues group and individual
annuities and life insurance.

The Company is a wholly owned  subsidiary  of Allstate  Life  Insurance  Company
("Allstate Life"), a stock life insurance company incorporated under the laws 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.  With the exception of directors' qualifying shares,
all of the  outstanding  capital  stock of  Allstate  is  owned by The  Allstate
Corporation ("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.

REINSURANCE AGREEMENTS

The Company and Allstate  Life entered into a reinsurance  agreement,  effective
December 31, 1987,  under which the Company  reinsures  all of its business with
Allstate Life. Under the reinsurance agreement,  Purchase Payments under general
account  contracts  are  transferred  to and become  invested with the assets of
Allstate Life which 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 Contracts to the Owners.
Because the  reinsurance  obligations  of Allstate  Life to the Company would be
subordinated  by  operation  of  current  state  insurance   rehabilitation  and
liquidation   laws  to  the   obligations   of  Allstate   Life  to  its  direct
policyholders,  Allstate Life has established a trust arrangement  involving the
pledge of as- sets for the benefit of the  Company,  in an amount at least equal
to the net  statutory  reserves  under the  Contracts,  under the terms of which
legal  title to such  assets  would  transfer  to the  Company in the event that
Allstate Life should become impaired or insolvent.  Such arrangement should have
the effect of avoiding the risk of subordination by operation of state insurance
rehabilitation and liquidation laws.

INVESTMENTS BY THE COMPANY

The  Company's  general  account  assets  must be invested  in  accordance  with
applicable  state laws.  These laws govern the nature and quality of investments
that may be made by life insurance  companies and the percentage of their assets
that may be committed to any particular  type of investment.  In general,  these
laws  permit  investments,  within  specified  limits  and  subject  to  certain
qualifications,  in federal, state, and municipal obligations,  corporate bonds,
preferred  stocks,  real  estate  mortgages,   real  estate  and  certain  other
investments.  All of the Company's  general account assets are available to meet
the Company's obligations.

The Company will primarily invest its general account assets in investment-grade
fixed income securities including the following:

Securities   issued  by  the  United  States   Government  or  its  agencies  or
instrumentalities,  which  may or may not be  guaranteed  by the  United  States
Government;

Debt  instruments,  including,  but not limited to,  issues of or  guaranteed by
banks or bank holding  companies,  and of corporations,  which are deemed by the
Company's  management  to  have  qualities  appropriate  for  inclusion  in this
portfolio;

Commercial mortgages,  mortgage-backed  securities collateralized by real estate
mortgage loans, or securities  collateralized by other assets,  that are insured
or  guaranteed  by the  Federal  Home Loan  Mortgage  Association,  the  Federal
National Mortgage  Association or the Government National Mortgage  Association,
or that have an  investment  grade at time of purchase  within the four  highest
grades  assigned  by  Moody's  Investors  Services,  Inc.  (Aaa,  Aa, A or Baa),
Standard  &  Poor's  Corporation  (AAA,  AA, A or BBB) or any  other  nationally
recognized rating service;

Commercial paper,  cash, or cash equivalents,  and other short-term  investments
having a maturity  of less than one year that are  considered  by the  Company's
management  to have  investment  quality  comparable  to  securities  having the
ratings stated above.

In addition, interest rate swaps, futures, options, rate caps, and other hedging
instruments may be used solely for non-speculative hedging purposes. Anticipated
use of these financial  instruments  shall be limited to protecting the value of
portfolio  sales or  purchases,  or to enhance  yield  through the creation of a
synthetic security.

In addition,  the Company  maintains  certain unitized  separate  accounts which
invest  in  shares  of an  open-end  investment  company  registered  under  the
Investment  Company Act of 1940.  These separate  account assets which relate to
the  Company's  variable  annuity  contracts,   do  not  support  the  Company's
obligations under the Contracts.

                     Management's Discussion and Analysis
               of Financial Condition and Results of Operations



      The  following  discussion  highlights   significant  factors  influencing
results of  operations  and changes in  financial  position of  Northbrook  Life
Insurance  Company (the  "Company").  It should be read in conjunction  with the
financial statements and related notes.

      The Company,  a wholly owned subsidiary of Allstate Life Insurance Company
("ALIC"),  which is wholly owned by Allstate Insurance Company ("AIC"), a wholly
owned subsidiary of The Allstate Corporation, markets life insurance and annuity
products  through Dean Witter Reynolds Inc., a wholly owned subsidiary of Morgan
Stanley, Dean Witter, Discover & Co.

      The Company issues flexible  premium deferred  variable annuity  contracts
and variable  life  policies,  the assets and  liabilities  of which are legally
segregated and reflected as Separate  Account assets and  liabilities.  Separate
Account  assets and  liabilities  are carried at fair value in the statements of
financial  position.  Investment  income  and  realized  gains and losses of the
Separate  Accounts  accrue  directly to the  contractholders  (net of fees) and,
therefore, are not included in the Company's statements of operations.

      The Company and ALIC have reinsurance  agreements under which all contract
and policy related  transactions are transferred to ALIC. The Company's  results
of  operations  include only  investment  income and realized  capital gains and
losses  earned on the assets of the  Company  that are not  transferred  to ALIC
under the reinsurance agreements.

      Net income for 1997 and 1996  increased  $120  thousand and $39  thousand,
respectively,  due to  increased  net  investment  income  partially  offset  by
realized capital losses.

      Pretax net investment  income increased by $258 thousand,  or 5.3% in 1997
and $106 thousand,  or 2.2% in 1996.  Additional investment income was earned on
higher  investment  balances  arising from  positive  cash flows from  operating
activities, partially offset by increased investment expenses.

      Realized  capital  losses were $44 thousand and $13 thousand  after tax in
1997 and 1996, respectively, and arose principally from the sale of fixed income
securities,  the  proceeds  of  which  were  used  to  acquire  higher  yielding
investments.  Realized capital gains in 1995 of $44 thousand after tax were the
result of the sale of fixed  income  securities  sold in  response to changes in
market conditions.

(1) Fixed income securities are carried at fair value.  Amortized cost for these
    securities   was  $72,491  and  $65,500  at  December  31,  1997  and  1996,
    respectively.


      The   Company's   fixed   income   securities    portfolio   consists   of
mortgage-backed  securities,  publicly traded corporate bonds,  U.S.  government
bonds and tax-exempt  municipal  bonds.  The Company  generally  holds its fixed
income  securities for the long term, but has classified all of these securities
as available for sale to allow maximum flexibility in portfolio management.

      Investments  grew $5.4  million,  or 7.2%,  during 1997  primarily  due to
amounts  invested  from  positive  cash  flows  generated  from  operations  and
increased  unrealized  capital gains of $1.9 million on fixed income securities.
At  December  31,  1997,  unrealized  net  capital  gains  on the  fixed  income
securities  portfolio were $3.9 million  compared to $2.0 million as of December
31, 1996. The increase in the unrealized gain position is primarily attributable
to lower interest rates.

      At the end of 1997, all of the Company's fixed income securities portfolio
is  rated   investment   grade,   with  a  National   Association  of  Insurance
Commissioners ("NAIC") rating of 1 or a Moody's rating of Aaa, Aa or A.

      At  December  31,  1997  and  1996,   $39.0  million  and  $40.7  million,
respectively,  of  the  fixed  income  securities  portfolio  were  invested  in
mortgage-backed  securities  ("MBS").  At December 31, 1997,  all of the MBS had
underlying  collateral  that is guaranteed  by U.S.  government  entities,  thus
credit risk was minimal.

      MBS,  however,  are  subject to  interest  rate risk as the  duration  and
ultimate  realized yield are affected by the rate of repayment of the underlying
mortgages.  The Company  attempts to limit  interest rate risk by purchasing MBS
whose  cost  does  not  significantly  exceed  par  value,  and  with  repayment
protection  to provide a more certain cash flow to the Company.  At December 31,
1997,  the  amortized  cost of the MBS  portfolio  was  below  par value by $1.5
million and over 10% of the MBS portfolio  was invested in planned  amortization
class  bonds.  This type of MBS is purchased  to provide  additional  protection
against rising interest rates.

      The Company  closely  monitors its fixed income  securities  portfolio for
declines  in value  that are other  than  temporary.  Securities  are  placed on
non-accrual  status  when they are in  default or when the  receipt of  interest
payments is in doubt.

      The Company's  short-term  investment  portfolio was $3.0 million and $6.6
million  at  December  31,  1997 and 1996,  respectively.  The  Company  invests
available  cash balances  primarily in taxable  short-term  securities  having a
final maturity date or redemption date of one year or less.

      During  1997,   contractholder  funds  decreased  by  $187.7  million  and
reinsurance  recoverable  from ALIC under  reinsurance  agreements  decreased by
$186.9 million.  Interest credited to contractholders and sales of fixed annuity
contracts  were  more  than  offset by fixed  annuity  surrenders,  withdrawals,
policyholder transfers from fixed annuity contracts to flexible premium deferred
variable annuity contracts, and benefits paid. Reinsurance recoverable from ALIC
relates to contract benefit obligations ceded to ALIC.

      Separate  Account  assets  and  liabilities  increased  by $1.36  billion,
primarily  attributable to sales of flexible premium  deferred  variable annuity
contracts,   the  favorable  investment  performance  of  the  Separate  Account
investment  portfolios  and transfers  from fixed annuity  contracts,  partially
offset by variable annuity surrenders and withdrawals.

Market Risk

      Market risk is the risk that the Company  will incur losses due to adverse
changes in market rates and prices.  The Company's  primary market risk exposure
is to changes in interest rates. Interest rate risk is the risk that the Company
will incur  economic  losses due to adverse  changes in interest  rates,  as the
Company invests substantial funds in interest-sensitive assets.

      One way to quantify  this  exposure is  duration.  Duration  measures  the
sensitivity  of the fair  value of assets to  changes  in  interest  rates.  For
example,  if  interest  rates  increase  1%,  the fair  value of an asset with a
duration of 5 years is expected  to  decrease in value by  approximately  5%. At
December 31, 1997, the Company's asset duration was approximately 4.7 years.

      To  calculate  duration,  the  Company  projects  asset  cash  flows,  and
discounts  them to a net  present  value  basis  using a  risk-free  market rate
adjusted for credit  quality,  sector  attributes,  liquidity and other specific
risks.  Duration is calculated by revaluing  these cash flows at an  alternative
level of interest rates,  and  determining  the percentage  change in fair value
from the base case. The projections  include  assumptions (based upon historical
market and  Company  specific  experience)  reflecting  the  impact of  changing
interest rates on the prepayment  and/or option features of  instruments,  where
applicable.  Such assumptions  relate primarily to  mortgage-backed  securities,
collateralized mortgage obligations, and municipal and corporate obligations.

      Based  upon  the  information  and  assumptions  the  Company  uses in its
duration  calculation and in effect at December 31, 1997,  management  estimates
that a 100 basis point  immediate,  parallel  increase in interest  rates ("rate
shock")  would  decrease  the  net  fair  value  of  its  total  investments  by
approximately  $3.6 million.  The selection of a 100 basis point  immediate rate
shock should not be construed as a prediction  by the  Company's  management  of
future market events;  but rather, to illustrate the potential impact of such an
event.

      To the extent that actual  results differ from the  assumptions  utilized,
the Company's duration and rate shock measures could be significantly  impacted.
Additionally,  the Company's  calculation assumes that the current  relationship
between  short-term and long-term interest rates (the term structure of interest
rates) will remain constant over time. As a result,  these  calculations may not
fully  capture  the  impact of  non-parallel  changes in the term  structure  of
interest rates and/or large changes in interest rates.

      In formulating  and  implementing  policies for investing new and existing
funds, AIC, as parent company of ALIC,  administers and oversees investment risk
management  processes  primarily through three oversight  bodies:  the Boards of
Directors  and  Investment  Committees of its  operating  subsidiaries,  and the
Credit and Risk  Management  Committee  ("CRMC").  The Boards of  Directors  and
Investment Committees provide executive oversight of investment activities.  The
CRMC  is a  senior  management  committee  consisting  of the  Chief  Investment
Officer,  the Investment  Risk Manager,  and other  investment  officers who are
responsible  for the  day-to-day  management  of market risk.  The CRMC meets at
least monthly to provide detailed oversight of investment risk, including market
risk.

      AIC has  investment  guidelines  that  define the  overall  framework  for
managing market and other investment risks,  including the  accountabilities and
controls  over  these  activities.  In  addition,  AIC has  specific  investment
policies for each of its affiliates,  including the Company,  that delineate the
investment  limits  and  strategies  that  are  appropriate  for  the  Company's
liquidity, surplus, product and regulatory requirements.

Liquidity and Capital Resources

      Under  the terms of  reinsurance  agreements,  premiums  and  deposits  on
universal life policies and investment  contracts,  excluding  those relating to
Separate  Accounts,  are  transferred  to ALIC,  which  maintains the investment
portfolios  supporting  the Company's  products.  The Company  continues to have
primary liability as a direct insurer for risks reinsured.

      The NAIC has a standard for assessing the solvency of insurance companies,
which is referred to as risk-based capital ("RBC").  The requirement consists of
a  formula  for  determining  each  insurer's  RBC  and a model  law  specifying
regulatory  actions if an insurer's RBC falls below  specified  levels.  The RBC
formula for life insurance companies  establishes capital requirements  relating
to insurance, business, asset and interest rate risks. At December 31, 1997, RBC
for the Company was  significantly  above a level that would require  regulatory
action.

Year 2000

         The Company is heavily  dependent upon complex computer systems for all
phases of its operations,  including  customer service,  and policy and contract
administration.  Since many of the Company's  older computer  software  programs
recognize  only the last two digits of the year in any date,  some  software may
fail to operate  properly  in or after the year  1999,  if the  software  is not
reprogrammed or replaced, ("Year 2000 Issue"). The Company believes that many of
its  counterparties  and suppliers also have Year 2000 Issues which could affect
the Company.  In 1995, AIC commenced a plan intended to mitigate  and/or prevent
the  adverse  effects  of Year 2000  Issues.  These  strategies  include  normal
development and enhancement of new and existing  systems,  upgrades to operating
systems already covered by maintenance  agreements and modifications to existing
systems to make them Year 2000  compliant.  The plan also  includes  the Company
actively working with its major external  counterparties and suppliers to assess
their  compliance  efforts  and the  Company's  exposure  to them.  The  Company
presently  believes that it will resolve the Year 2000 Issue in a timely manner,
and the financial  impact will not materially  affect its results of operations,
liquidity  or  financial  position.  Year 2000 costs are and will be expensed as
incurred.

Pending Accounting Standards

      In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 130 "Reporting Comprehensive Income"
and SFAS No. 131  "Disclosures  About  Segments  of an  Enterprise  and  Related
Information." SFAS No. 130 requires the presentation of comprehensive  income in
the financial  statements.  Comprehensive income is a measurement of all changes
in equity that result from  transactions  and other  economic  events other than
transactions  with  stockholders.  The  requirements  of this  statement will be
adopted effective January 1, 1998.

      SFAS No. 131 redefines how segments are determined and requires additional
segment  disclosures  for  both  annual  and  quarterly  reporting.  Under  this
statement, segments are determined using the "management approach" for financial
statement  reporting.  The management approach is based on the way an enterprise
makes  operating  decisions  and assesses  performance  of its  businesses.  The
Company is  currently  reviewing  the  requirements  of this SFAS and has yet to
determine its impact on its current reporting segments. The requirements of this
statement will be adopted effective December 31, 1998.


      In December  1997,  the Accounting  Standards  Executive  Committee of the
American Institute of Certified Public Accountants ("AICPA") issued Statement of
Position  ("SOP")  97-3,  "Accounting  by Insurance  and Other  Enterprises  for
Insurance-related  Assessments."  The SOP provides  guidance  concerning when to
recognize  a  liability  for   insurance-related   assessments   and  how  those
liabilities  should be  measured.  Specifically,  insurance-related  assessments
should be recognized as liabilities when all of the following criteria have been
met: a) an assessment has been imposed or it is probable that an assessment will
be imposed,  b) the event obligating an entity to pay an assessment has occurred
and  c)  the  amount  of  the  assessment  can  be  reasonably  estimated.   The
requirements  of this  standard  will be adopted in 1999 and are not expected to
have a material  impact on the results of  operations,  cash flows or  financial
position of the Company. The SOP is expected to be adopted in 1999.

      In March 1998, the Accounting  Standards  Executive Committee of the AICPA
issued SOP 98-1,  "Accounting  for the Costs of Computer  Software  Developed or
Obtained for  Internal  Use." The SOP provides  guidance on  accounting  for the
costs of computer software developed or obtained for internal use. Specifically,
certain external, payroll and payroll related costs should be capitalized during
the application development state of a project and depreciated over the computer
software's useful life. The Company  currently  expenses these costs as incurred
and is  evaluating  the  effects of this SOP on its  accounting  for  internally
developed software. The SOP is expected to be adopted in 1998.


Forward-Looking Statements

      The statements contained in this Management's Discussion and Analysis that
are not historical information are forward-looking  statements that are based on
management's  estimates,  assumptions and  projections.  The Private  Securities
Litigation Reform Act of 1995 provides a safe harbor under The Securities Act of
1933 and The Securities Exchange Act of 1934 for forward-looking statements.

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 1,700
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 reinsures all net business
of the Company.  A.M.  Best Company also assigns the Company the rating of A+(r)
because the Company  reinsures all net business with Allstate  Life.  Standard &
Poor's  Insurance  Rating  Services  assigns AA+  (Excellent)  to the  Company's
claims-paying  ability and Moody's  assigns Aa2 (Excellent)  financial  strength
rating to the  Company.  The  Company  shares the same  ratings  of its  parent,
Allstate Life Insurance Company.


EMPLOYEES
As of December 31, 1997,  Northbrook Life had approximately 124 employees at its
Home Office in Northbrook, Illinois.


PROPERTIES
The Company  occupies  office space  provided by Allstate  Insurance  Company 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 de- tailed
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.  The  directors  and executive  officers are listed
below,  together  with  information  as to their  ages,  dates of  election  and
principal  business  occupations during the last five years (if other than their
present business occupations).  Except as otherwise indicated, the directors and
executive officers of the Company have been associated with the Company for more
than five years in the position shown or in other positions.

INDEPENDENT AUDITORS' REPORT


TO THE BOARD OF DIRECTORS AND SHAREHOLDER OF
NORTHBROOK LIFE INSURANCE COMPANY:

We have audited the accompanying  Statements of Financial Position of Northbrook
Life Insurance Company (the "Company") as of December 31, 1997 and 1996, and the
related Statements of Operations,  Shareholder's  Equity and Cash Flows for each
of the three  years in the period  ended  December  31,  1997.  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 the  Company as of December  31, 1997 and
1996, and the results of its operations and its cash flows for each of the three
years in the  period  ended  December  31,  1997 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.

                       NORTHBROOK LIFE INSURANCE COMPANY
                         NOTES TO FINANCIAL STATEMENTS
                                ($ IN THOUSANDS)

1.    General

Basis of presentation
The accompanying  financial  statements  include the accounts of Northbrook Life
Insurance  Company (the  "Company"),  a wholly owned subsidiary of Allstate Life
Insurance Company ("ALIC"),  which is wholly owned by Allstate Insurance Company
("AIC"),   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").  These financial  statements have been
prepared in conformity with generally accepted accounting principles.

To conform  with the 1997  presentation,  certain  amounts  in the prior  years'
financial statements and notes have been reclassified.

Nature of operations
The Company  markets life  insurance and annuity  products in the United States
through Dean Witter  Reynolds Inc.  ("Dean Witter") (see Note 4), a wholly owned
subsidiary  of Morgan  Stanley,  Dean  Witter,  Discover  & Co.  Life  insurance
contracts   sold   by   the   Company   include   universal   life   and   other
interest-sensitive  life and  variable  life  products.  Annuities  include both
deferred  annuities,  such as  variable  annuities  and fixed  rate  single  and
flexible premium annuities, and immediate annuities.

Annuity contracts and life insurance policies issued by the Company are subject
to  discretionary  withdrawal or surrender by  customers,  subject to applicable
surrender  charges.  These  policies and contracts are reinsured  with ALIC (see
Note 3), which invests  premiums and deposits to provide cash flows that will be
used to fund  future  benefits  and  expenses.  In order to support  competitive
crediting rates and limit interest rate risk, ALIC, as the Company's  reinsurer,
adheres to a basic philosophy of matching assets with related  liabilities while
maintaining  adequate  liquidity and a prudent and  diversified  level of credit
risk.

The  Company  monitors  economic  and  regulatory  developments  which have the
potential to impact its business. There continues to be new and proposed federal
and  state   regulation   and   legislation   that  would  allow  banks  greater
participation in the securities and insurance businesses,  which will present an
increased  level of  competition  for sales of the  Company's  life and  annuity
products.  Furthermore, the market for deferred annuities and interest-sensitive
life  insurance is enhanced by the tax incentives  available  under current law.
Any legislative  changes which lessen these  incentives are likely to negatively
impact the demand for these products.

Enacted and pending state  legislation to permit mutual  insurance  companies to
convert to a hybrid  structure  known as a mutual  holding  company could have a
number  of  significant  effects  on  the  Company  by (1)  increasing  industry
competition through  consolidation caused by mergers and acquisitions related to
the new  corporate  form of  business;  (2)  increasing  competition  in capital
markets; and (3) reopening  stock/mutual company  disagreements  related to such
issues as taxation disparity between mutual and stock insurance companies.

The Company is authorized to sell life and annuity products in all states except
New York,  as well as in the  District  of  Columbia  and Puerto  Rico.  The top
geographic  locations for statutory  premiums and deposits earned by the Company
are California, Florida and Texas for the year ended December 31, 1997. No other
jurisdiction  accounted for more than 5% of statutory premiums and deposits. All
premiums and contract charges are ceded to ALIC under reinsurance agreements.

2.    Summary of Significant Accounting Policies

Investments
Fixed income securities include bonds and mortgage-backed securities. All fixed
income  securities  are  carried  at fair  value and may be sold  prior to their
contractual  maturity  ("available for sale").  The difference between amortized
cost and fair value,  net of deferred  income taxes, is reflected as a component
of shareholder's equity.  Provisions are recognized for declines in the value of
fixed income  securities  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.

Reinsurance
The Company has reinsurance  agreements whereby all premiums,  contract charges,
credited  interest,  policy benefits and certain  expenses are ceded to ALIC and
reflected net of such  cessions in the  statements  of  operations.  The amounts
shown in the  Company's  statements of  operations  relate to the  investment of
those assets of the Company that are not  transferred to ALIC under  reinsurance
agreements.  Reinsurance recoverable and the related reserve for life-contingent
contract  benefits  and  contractholder  funds are  reported  separately  in the
statements  of  financial  position.  The  Company  continues  to  have  primary
liability as the direct insurer for risks reinsured.

Recognition of premium revenues and contract charges
Revenues on interest-sensitive life insurance policies are comprised of contract
charges and fees,  and are  recognized  when assessed  against the  policyholder
account  balance.  Revenues on most annuities,  which are considered  investment
contracts,  include  contract charges and fees for contract  administration  and
surrenders.  These  revenues  are  recognized  when levied  against the contract
balance.

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 at the enacted tax
rates, and reflect the impact of reinsurance  agreements.  Deferred income taxes
arise  primarily  from  unrealized  capital  gains and  losses  on fixed  income
securities carried at fair value.

Separate Accounts
The Company issues flexible  premium  deferred  variable  annuity  contracts and
single premium  variable life policies,  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 (Northbrook Variable
Annuity  Account,  Northbrook  Variable  Annuity  Account II and Northbrook Life
Variable Life Separate  Account A, unit  investment  trusts  registered with the
Securities and Exchange Commission).

Assets of the Separate Accounts are carried at fair value. Investment income and
realized  capital gains and losses of the Separate  Accounts  accrue directly to
the  policy-  and  contractholders  and,  therefore,  are  not  included  in the
Company's  statements of  operations.  Revenues to the Company from the Separate
Accounts consist of contract  maintenance fees,  administration  fees, mortality
and expense risk charges, cost of insurance charges and tax expense charges, all
of which are ceded to ALIC.

Reserve for life-contingent contract benefits
The reserve for life-contingent  contract benefits,  which relates to structured
settlement  annuities and  supplemental  contracts with life  contingencies,  is
computed on the basis of assumptions as to future investment  yields,  mortality
and expenses.  These  assumptions  include  provisions for adverse deviation and
generally vary by such  characteristics  as type of coverage,  year of issue and
policy duration. Reserve interest rates ranged from 4.00% to 11.00% during 1997.

Contractholder funds
Contractholder funds arise from the issuance of individual or group policies and
contracts  that include an investment  component,  including  most annuities and
universal  life  policies.  Payments  received are recorded as  interest-bearing
liabilities.  Contractholder  funds are equal to deposits  received and interest
credited  to the  benefit  of the  contractholder  less  withdrawals,  mortality
charges and  administrative  expenses.  During 1997,  credited interest rates on
contractholder  funds ranged from 3.30% to 9.51% for those  contracts with fixed
interest rates and from 3.25% to 7.39% for those with flexible rates.

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.    Related Party Transactions

Reinsurance
Premiums  and  contract  charges  ceded to ALIC were $1,979 and $83,559 in 1997,
$3,775 and  $60,744  in 1996,  and  $2,284  and  $52,348 in 1995,  respectively.
Credited  interest,  policy  benefits  and  expenses  ceded to ALIC  amounted to
$201,526, $218,088 and $229,525 in 1997, 1996 and 1995, respectively. Investment
income earned on the assets which support  contractholder  funds is not included
in the Company's  financial  statements as those assets are owned and managed by
ALIC under the terms of reinsurance agreements.

Business operations
The Company  utilizes  services and business  facilities  owned or leased,  and
operated by AIC in conducting its business  activities.  The Company  reimburses
AIC for the  operating  expenses  incurred by AIC 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 $7,842,  $8,074 and $5,341 in 1997, 1996 and 1995,  respectively.  Of these
costs,  the Company retains  investment  related  expenses.  All other costs are
ceded to ALIC under reinsurance agreements.


4.  Exclusive Distribution Agreement

The  Company  and ALIC have a  strategic  alliance  with Dean Witter to develop,
market and distribute  proprietary  annuity and life insurance  products through
Dean Witter account  executives.  Dean Witter  provides a portion of the funding
for these products through loans to an affiliate of the Company. An affiliate of
Dean Witter,  Dean Witter  InterCapital  Inc., is the investment manager for the
Dean Witter  Variable  Investment  Series,  the funds in which the assets of the
Separate Accounts are invested.

Under the terms of the  strategic  alliance,  the Company has agreed to use Dean
Witter as an exclusive distribution channel for the Company's products. Although
the  strategic  alliance  is  cancelable  by either  party,  termination  of the
alliance would not impact existing policies and contracts.

6.    Financial Instruments

In the normal  course of  business,  the  Company  invests in various  financial
assets and incurs various  financial  liabilities.  The fair value  estimates of
financial  instruments  presented  below are not  necessarily  indicative of the
amounts  the  Company  might  pay or  receive  in  actual  market  transactions.
Potential  taxes  and  other  transaction  costs  have  not been  considered  in
estimating fair value. The disclosures that follow do not reflect the fair value
of the Company as a whole  since a number of the  Company's  significant  assets
(including  reinsurance  recoverable) and liabilities (including deferred income
taxes and reserve for  life-contingent  contract  benefits)  are not  considered
financial  instruments  and are not  carried  at fair  value.  Other  assets and
liabilities considered financial instruments, such as accrued investment income,
are generally of a short-term  nature.  It is assumed that their  carrying value
approximates fair value.

Financial assets
The  carrying  value and fair value of  financial  assets at December 31, are as
follows:

</TABLE>

Fair  values for fixed  income  securities  are based on quoted  market  prices.
Short-term  investments  are highly liquid  investments  with maturities of less
than one year whose carrying value  approximates  fair value.  Separate Accounts
assets are carried in the statements of financial position at fair value.

</TABLE>

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  account  balance  less  surrender  charges.  The  fair  value of
immediate annuities and annuities without life contingencies with fixed terms is
estimated  using  discounted  cash flow  calculations  based on  interest  rates
currently  offered for  contracts  with similar  terms and  durations.  Separate
Accounts liabilities are carried at the fair value of the underlying assets.


7.    Income Taxes

The Company joins the Corporation and its other eligible  domestic  subsidiaries
in the filing of a consolidated federal income tax return (the "Allstate Group")
and is party to a federal  income tax  allocation  agreement  (the "Tax  Sharing
Agreement").  Under the Tax Sharing  Agreement,  the Company paid to or received
from the Corporation the amount,  if any, by which the Allstate  Group's federal
income tax  liability  was affected by virtue of inclusion of the Company in the
consolidated  federal  income  tax  return.  Effectively,  this  results  in the
Company's annual income tax provision being computed,  with  adjustments,  as if
the Company filed a separate return.

Prior to the  Distribution,  the  Corporation  and all of its eligible  domestic
subsidiaries, including the Company, 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 "Sears Tax Sharing  Agreement").  Under the Sears 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 Company in the
consolidated  federal  income tax  return.  Effectively,  this  resulted  in the
Company's  annual income tax provision  being  computed as if the Allstate Group
filed a separate  consolidated  return,  except that items such as net operating
losses,  capital  losses or similar  items,  which might not be  recognized in a
separate return, were allocated according to the Sears Tax Sharing Agreement.

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
Sears Tax Sharing  Agreement with respect to the Allstate Group's federal income
tax liability.

Prior to January 1, 1984,  the Company was entitled to exclude  certain  amounts
from taxable  income and  accumulate  such amounts in a  "policyholder  surplus"
account.  The balance in this account at December 31, 1997,  approximately  $16,
will result in federal income taxes payable of $6 if distributed by the Company.
No  provision  for taxes has been made as the Company has no plan to  distribute
amounts  from this  account.  No  further  additions  to the  account  have been
permitted since the Tax Reform Act of 1984.

Permitted statutory accounting practices
The Company  prepares its statutory  financial  statements  in  accordance  with
accounting  principles  and  practices  prescribed  or permitted by the Illinois
Department of Insurance.  Prescribed  statutory  accounting  practices include a
variety of publications of the National  Association of Insurance  Commissioners
("NAIC"), as well as state laws,  regulations and general  administrative rules.
Permitted statutory  accounting practices encompass all accounting practices not
so prescribed.  The Company follows a permitted  statutory  accounting  practice
whereby it includes amounts  receivable from an affiliated  insurance company in
statutory  admitted assets at a level which exceeds the threshold  prescribed by
the Illinois Department of Insurance by $7,737.

Final  approval  of the  NAIC's  proposed  "Comprehensive  Guide"  on  statutory
accounting  principles  is expected in early  1998.  Implementation  could be as
early as January 1, 1999. The  requirements of the  Comprehensive  Guide are not
expected to have a material impact on statutory surplus of the Company.

Under the NAIC's proposed accounting  practices,  the Company's practice related
to its receivable from affiliate will be prescribed rather than permitted.

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 1998 without  prior  approval of the Illinois  Department of Insurance is
$7,318.

                             MARKET VALUE ADJUSTMENT

The Market Value Adjustment is based on the following:

I=  the effective annual Interest Crediting Rate for that Sub-Account

N=  the  number  of  complete  days  from  the  withdrawal  to  the  end  of the
Sub-Account's Guarantee Period; and

J= the current interest rate credited for contracts,  on the date the withdrawal
request is received, for a Guarantee Period of duration N. If a Guarantee Period
of duration N is not currently  being offered,  J will be determined by a linear
interpolation (weighted average). If N is less than or equal to 365 days, J will
be the rate for a Guarantee Period of duration 365.

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

  [.9 x (I-J) x (N/365)].

The  amount  withdrawn  less  any  applicable  Free  Withdrawal  Amount  will be
multiplied by the Market Value  Adjustment  factor to determine the Market Value
Adjustment.

EXAMPLE 1: (Assumes declining interest rates)


Step 1: Calculate Account Value at End of Contract Year 3:

                       = 10,000.00 x (1.045)3 = $11,411.66

Step 2: Calculate The Amount Withdrawn in Excess of the Free Withdrawal Amount:

Amount Withdrawn:  11,411.66 Free Withdrawal  Amount: .10 x 10,000.00 = 1,000.00
Amount Withdrawn in Excess of the Free Withdrawal Amount:

                       = 11,411.66 - 1,000.00 = $10,411.66

Step 3: Calculate the Withdrawal Charge:

                          = .0225 x 10,411.66 = $234.26

Step 4: Calculate the Market Value Adjustment:

I=   4.5%

J=   4.2%

N=   730 days

Market Value Adjustment Factor: .9 x (I-J) x (N/365)

                    = .9 x (.045 - .042) x (730/365) = .0054

Market Value Adjustment = Factor x Amount in Excess of Free Withdrawal Amount:

                          = .0054 x 10,411.66 = $56.22

Step 5: Calculate The Net Surrender Value at End of Contract Year 3:

                    = 11,411.66 - 234.26 + 56.22 = $11,233.62

EXAMPLE 2: (Assumes rising interest rates)

Step 1: Calculate Account Value at End of Contract Year 3:

                       = 10,000.00 x (1.045)3 = $11,411.66

Step 2: Calculate The Amount Withdrawn in Excess of the Free Withdrawal Amount:

Amount Withdrawn: 11,411.66
Free Withdrawal Amount: .10 x 10,000.00 = 1,000.00 Amount Withdrawn in Excess of
the Free Withdrawal Amount:

                       = 11,411.66 - 1,000.00 = $10,411.66

Step 3: Calculate the Withdrawal Charge:

                          = .0225 x 10,411.66 = $234.26

Step 4: Calculate the Market Value Adjustment:
I= 4.5%
J= 4.8%
N = 730 days

Market Value Adjustment Factor: .9 x (I-J) x (N/365)

                    = .9 x (.045 - .048) x (730/365) = -.0054

Market Value Adjustment = Factor x Amount in Excess of Free Withdrawal Amount:

                         = -.0054 x 10,411.66 = -$56.22

Step 5: Calculate The Net Surrender Value at End of Contract Year 3:

                                 = 11,411.66 - 234.26 - 56.22 = $11,121.18
