This Prospectus describes the group and individual Flexible Premium Deferred

THE CONTRACTS
       
1. WHAT IS THE PURPOSE OF THE CONTRACT?
 
The Contract described in this Prospectus 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. The Contract has an Accumulation Phase and a
Payout Phase. The Accumulation Phase is the first of the two phases and begins
on the Issue Date and continues until the Payout Start Date. During the
Accumulation Phase, interest is credited to the Purchase Payment(s) and both a
cash withdrawal benefit and a Death Benefit are available. The Payout Phase
begins on the Payout Start Date and provides Income Payments under an Income
Plan. The Payout Phase continues until the Company makes the last payment as
provided by the Income Plan.
 
2. HOW IS A CONTRACT PURCHASED?
 
By submitting a Purchase Payment to an Account Executive of Dean Witter, the
principal underwriter of the Contracts. Presently, the Company will accept an
initial Purchase Payment of $1,000, but reserves the right to increase this
amount to no more than $4,000 ($1,000 for a Qualified Contract). The Owner must
select the Guarantee Period(s) in which to allocate the Purchase Payment. The
Company currently offers a five-year Guarantee Period. Additional Guarantee
Periods will be offered at the discretion of the Company and may range from one
to ten years. Additional Purchase Payments of $1,000 or more may be added to
the Contract. No less than $1,000 may be allocated to any one Guarantee Period.
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 and reserves the right to suspend sales of the
Contract. The Company also reserves the right to limit its acceptance of
annuity exchanges pursuant to Section 1035 of the Internal Revenue Code as well
as trustee to trustee transfers from one Individual Retirement Account to
another or from one Tax Sheltered Annuity to another, or direct rollovers of
"eligible rollover contributions" from qualified plans.
 
3. DOES THIS CONTRACT HAVE A FREE-LOOK PROVISION?
 
Yes. The Owner may cancel the Contract anytime within 20 days after the receipt
of the Contract and receive a full refund of the entire Purchase Payment.
 
4. CAN ADDITIONS BE MADE TO THE CONTRACT AFTER THE INITIAL PURCHASE PAYMENT?
 
Yes, additional Purchase Payments may be made at any time during the
Accumulation Phase of the Contract. Subsequent Purchase Payments must be at
least $1,000 and may be made from a bank account or a Dean Witter Active
AssetsTM Account through Automatic Additions (the Automatic Additions Program
is not available for Qualified Contracts issued pursuant to a Dean Witter
Custodial Account). For each Purchase Payment, the Owner must select a
Guarantee Period(s) to which the Purchase Payment will be allocated. The
Company reserves the right to limit the number of additional Purchase Payments.
 
5. ONCE A CONTRACT IS PURCHASED, HOW IS THE OWNER INFORMED AS TO THE STATUS OF
THE CONTRACT?
 
There are several ways an Owner may receive information about the Contract. At
least once a year, prior to the Payout Start Date, the Owner will be sent a
statement containing Account Value information of the Contract. The Owner may
also direct questions about the Contract to his/her Dean Witter Account
Executive. Another option the Owner has is to call the Company's customer
support unit directly at 1-800-654-2397.
 
THE ACCUMULATION PHASE
 
6. HOW IS INTEREST CREDITED TO THE CONTRACT?
 
Interest will be credited to initial Purchase Payments from the Issue Date.
Interest will be credited to subsequent Purchase Payments from
                                       5
<PAGE>
 
the date of receipt. No deductions are made from Purchase Payments. Therefore,
the full amount of every Purchase Payment is invested in a Sub-Account for
accumulation of interest. Interest is credited daily to each Guarantee Period
in the Contract and is based upon the interest rate of the Guarantee Period
which has been chosen.
 
The following example illustrates how a Sub-Account Value would grow given an
assumed Purchase Payment, Guarantee Period, and effective annual interest rate.
The effective annual interest rate is defined as the yield resulting when
interest credited at the underlying daily rate has compounded for a full year.

NOTE: The above 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 Preferred 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.
 
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.

7. WHAT HAPPENS TO THE SUB-ACCOUNT VALUE AT THE END OF A GUARANTEE PERIOD?
 
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. Within 30
days after the end of a Guarantee Period 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 Guarantee Period expired; or
 . notify the Company to apply the Sub-Account Value to a Guarantee Period of
   a new duration, from among those available, to be established on the day
   the previous Guarantee Period expired; or
 . receive a portion of the Sub-Account Value or the entire Sub-Account Value
   through a Partial Withdrawal without incurring a Withdrawal Charge or
   Market Value Adjustment. In this case, the amount withdrawn will be deemed
   to have been renewed at the shortest Guarantee Period then being offered
   with current interest credited from the date the Guarantee Period expired.
 
8. CAN A PARTIAL WITHDRAWAL OR A FULL SURRENDER BE TAKEN AT ANY TIME?
 
Yes. As long as the Contract is still in the Accumulation Phase and has not
entered the Payout Phase, the Owner may withdraw money from the Contract or
surrender the Contract at any time (a Withdrawal Charge and Market Value
Adjustment and taxes may apply). Partial Withdrawals may be taken automatically
through Systematic Withdrawals (a Dean Witter Account Executive should be
consulted for information regarding Systematic Withdrawals). The Owner must
specify the Sub-Account from which the withdrawal will be taken. If any Partial
Withdrawal reduces a Sub-Account Value to less than $1,000, the withdrawal will
be treated as a request to withdraw the entire Sub-Account Value. The Company
may defer payment of any Partial Withdrawal or Full Surrender for a period not
exceeding six months from the date of the receipt of the request.
 
9. IF A PARTIAL WITHDRAWAL OR FULL SURRENDER IS REQUESTED, HOW IS THE AMOUNT
RECEIVED DETERMINED?
 
The main component in determining the amount received by the Owner is the amount
which was requested, however, there may be adjustments to the requested amount.
A Withdrawal Charge may reduce the amount requested. A Market Value Adjustment
may apply which will reduce or increase the amount requested. Premium taxes and
federal income tax withholding may apply and would reduce the amount requested.
In summary:
 
The amount received by the Owner under a partial withdrawal or surrender
request equals the amount requested less a Withdrawal Charge (if applicable)
plus or minus a Market Value Adjustment (if applicable) less premium taxes and
withholding (if applicable).
 
The questions which follow further clarify the components used in determining
the amount received upon a Partial Withdrawal or Full Surrender.
 
10. UPON A PARTIAL WITHDRAWAL OR FULL SURRENDER, IS THE ENTIRE AMOUNT REQUESTED
SUBJECT TO A WITHDRAWAL CHARGE AND A MARKET VALUE ADJUSTMENT?
 
No. Only amounts in excess of any remaining Preferred Withdrawal Amount within
a Sub-Account will be subject to a Withdrawal Charge and a Market Value
Adjustment. A Preferred Withdrawal Amount is available in every Sub-Account
year of a Guarantee Period and is equal to 10% of the Purchase Payment
allocated to the Guarantee Period. Any unused Preferred Withdrawal Amount in a
Sub-Account year may not be used to increase the Preferred Withdrawal Amount in
a subsequent Sub-Account year nor may it be used to increase the Preferred
Withdrawal Amount in another Guarantee Period.
 
In addition to the Preferred Withdrawal Amount, any amounts withdrawn from Sub-
Accounts which are within the first 30 days of their renewal Guarantee Periods
will be completely free from any Withdrawal Charge and Market Value Adjustment.
 
                                       7
<PAGE>
 
11. WHAT IS THE WITHDRAWAL CHARGE UPON A PARTIAL WITHDRAWAL OR FULL SURRENDER?
 
The Withdrawal Charge is 6% of all amounts withdrawn or surrendered which are
not exempt from charge as discussed in question 10, above.
 
12. WHAT IS THE MARKET VALUE ADJUSTMENT UPON A PARTIAL WITHDRAWAL OR FULL
SURRENDER?
 
The Market Value Adjustment will be applied to all amounts withdrawn or
surrendered which are not exempt from adjustment as discussed in question 10.
 
The Market Value Adjustment is to reflect the relationship between the current
Treasury Rate for the duration remaining in the Guarantee Period at the time of
the request for Partial Withdrawal or Full Surrender, and the Treasury Rate at
the time the Sub-Account was established for a maturity equal to the Sub-
Account guarantee period. Since current Treasury Rates are the basis for the
investment yields available at the time, the effect of the Market Value
Adjustment will be closely related to the levels of such yields. As such, the
Owner bears some investment risk under the Contract.
 
It is possible, therefore, that, should such yield increase significantly from
the time the Purchase Payment was made, coupled with the application of the
Withdrawal Charge, less premium taxes and withholding (if applicable), 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.
 
Generally, if the Treasury Rate at the time of establishing the Sub-Account is
lower than the applicable current Treasury Rate (interest rate for a duration
equal to the time remaining in the Sub-Account), then the Market Value
Adjustment will result in a lower payment upon Partial Withdrawal or Full
Surrender which may also be less than your original Purchase Payment.
Similarly, if the Treasury Rate at the time of establishing the Sub-Account is
higher than the applicable current Treasury Rate, then the Market Value
Adjustment will result in a higher payment upon Partial Withdrawal or Full
Surrender.
   
For example, assume the Owner purchases a Contract and selects an initial
Guarantee Period of five years and the Treasury Rate for that duration is
    %. Assume that at the end of 3 years, the Owner makes a Partial Withdrawal.
If the Treasury Rate for a 2 year period is     %, 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 Treasury
Rate for the 2 year period is     %, then the Market Value Adjustment will be
negative, which will result in a decrease in the amount payable to the Owner
upon a Partial Withdrawal.     
 
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.
 
13. THE IRS REQUIRES ANNUAL WITHDRAWALS TO BE TAKEN FROM QUALIFIED CONTRACTS
UPON ATTAINMENT OF AGE 70 1/2. WILL THESE WITHDRAWALS INCUR WITHDRAWAL CHARGES
AND MARKET VALUE ADJUSTMENTS?
 
No. Both the Withdrawal Charge and Market Value Adjustment will be waived on
withdrawals taken to satisfy IRS required distribution rules for this Contract.
 
14. WHAT ARE THE TAX IMPLICATIONS ASSOCIATED WITH THE CONTRACT?
 
It varies based upon the Owner's circumstances. Generally, the two areas which
may give rise to a taxable situation are personal federal and state income
taxation and taxation of the Company.
 
With respect to personal federal and state income tax, an annuity contract
Owner who is a natural person is not taxed on increases in the Account Value
until a distribution occurs. For federal income tax purposes, distributions
include the receipt of proceeds from loans and an assignment or pledge of any
portion of the value of the Contract, as well as withdrawals, Income Payments,
or Death Benefits. In addition, personal federal and state income tax
withholding may be deducted from Partial Withdrawal and Full Surrender
payments. Amounts withheld for
 
                                       8
<PAGE>
 
personal taxes do not necessarily represent the Owner's entire income tax
liability.
 
With respect to taxation of the Company, premium taxes and other applicable
taxes imposed on the Company may be deducted from the Contract's Purchase
Payment or Account Value upon Full Surrender or annuitization of the Contract.
Current premium tax rates range from 0 to 3.5%, but are subject to change by
state regulation.
 
There are several exceptions to the above generalizations. More complete
information can be found in the "Federal Tax Matters" section found on page 15
of this prospectus.
 
THE PARTIES TO THE CONTRACT
 
15. WHAT RIGHTS DOES AN OWNER HAVE IN THIS CONTRACT?
 
This Contract offers the Owner several rights. The Owner may:
 
 . receive any withdrawals or periodic Income Payments from the Contract,
   unless the Owner has directed the Company to pay them to someone else;
 . name and change the Owner, Beneficiary, and Annuitant (only if Owner is a
   natural person);
 . assign the Contract;
 . elect a Death Benefit option upon death of a co-owner or Annuitant; and
 . terminate the Contract.
 
The above may be subject to the rights of any irrevocable Beneficiary.
 
16. WHAT PURPOSE DOES THE ANNUITANT SERVE?
 
The Annuitant's life determines the Income Payments which will begin on the
Payout Start Date. This Contract requires an Annuitant at all times during the
Accumulation Phase and on the Payout Start Date. The Annuitant must be a
natural person. A Death Benefit may be payable upon the death of the Annuitant.
 
17. WHO IS THE BENEFICIARY TO THE CONTRACT?
 
The Beneficiary varies based upon who the Owner is, and the designation of the
parties to the Contract by the Owner.
 
If the Owner is a natural person, the Beneficiary will be determined from the
most recent written request of the Owner. If the Owner does not name a
Beneficiary or if the Beneficiaries named are no longer living, the Beneficiary
will be:
 
 . the Owner's spouse if living;
 . otherwise, the Owner's children, equally, if living;
 . otherwise, the Owner's estate.
 
If the Owner is a grantor trust, then the Beneficiary will be that same grantor
trust.
 
If the Owner is a non-natural person other than a grantor trust, the Owner is
also the Beneficiary, unless a different Beneficiary has been named.
 
18. WHAT PURPOSE DOES THE BENEFICIARY SERVE?
 
The Beneficiary becomes the new Owner if the sole surviving Owner dies prior to
the Payout Start Date. If the sole surviving Owner dies after the Payout Start
Date, the Beneficiary will receive any guaranteed Income Payments scheduled to
continue.
 
THE DEATH BENEFIT PROVISIONS
 
19. UPON DEATH OF THE OWNER, WHO IS THE NEW OWNER OF THE CONTRACT?
 
The new Owner is any surviving joint Owner(s) or if none, the Beneficiary.
 
20. UPON DEATH OF THE OWNER, WHAT OPTIONS DOES THE NEW OWNER HAVE?
 
In most cases, the new Owner of the Contract has the following three options:
 
 . receive the Cash Surrender Value within 5 years of the date of death; or
 
                                       9
<PAGE>
 
 . receive the Death Benefit in a lump sum. The Death Benefit is equal to the
   greater of the Account Value and the Cash Surrender Value; or
 . apply the Death Benefit to an Income Plan with Income Payments beginning
   within one year of the Date of Death. Income Payments must be made over the
   life of the new Owner, or a period not to exceed the life expectancy of the
   new Owner.
 
If the new Owner is the spouse of the deceased Owner, the new Owner may elect
to continue the Contract. See question 21, below.
 
If the new Owner is a non-natural person, then the Owner must receive the Death
Benefit in a lump sum.
 
Deaths should be reported to the Company as quickly as possible. If the Company
is not notified within 180 days of the date of death, the only option available
to the new Owner is to receive the Cash Surrender Value within 5 years of the
date of death. Any remaining funds will be distributed at the end of 5-year
period. The Contract should be referred to for the conditions and stipulations
which apply to each of the above options.
 
21. FOR A CONTRACT WITH SPOUSAL CO-OWNERS, WHAT HAPPENS TO THE CONTRACT UPON
THE DEATH OF ONE OF THE SPOUSES?
 
In addition to the options available in question 20, a surviving spousal Owner
has the following additional options:
 
 . continue the Contract as if the death had not occurred; and
 . if the Contract is continued, one withdrawal within the year of death is
   allowed which will not be assessed a Withdrawal Charge (a Market Value
   Adjustment will apply). The amount which may be withdrawn is limited only
   by the amount of the available Death Benefit.
 
22. IF THE OWNER IS NOT THE ANNUITANT AND THE ANNUITANT DIES, WHAT HAPPENS TO
THE CONTRACT?
 
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 and the Cash Surrender Value; or
 . apply the Death Benefit to an Income Plan.
 
Deaths should be reported to the Company as quickly as possible. If the Company
is not notified within 180 days of the date of death, the only option available
to the Owner is to continue the Contract as if the death had not occurred. The
Contract should be referred to for the conditions and stipulations which apply
to each of the above options.
 
THE PAYOUT PHASE
 
23. WHAT IS THE PAYOUT START DATE?
   
This is the date on which the Accumulation Phase ceases and the Payout Phase
begins. During the Payout Phase, the Owner receives Income Payments based upon
an Income Plan selected by the Owner from the Contract. The Payout Phase will
continue until the Company makes the last payment as provided by the Income
Plan chosen. The Owner may choose any Payout Start Date as long as it is on or
before the later of:     
 
 . the Annuitant's 90th birthday; or
 . the 10th anniversary of the Contract's Issue Date.
 
Unless the Owner notifies the Company in writing, the Payout Start Date will
depend on whether the Owner has a Non-Qualified or Qualified Contract. For Non-
Qualified Contracts, the Payout Start Date will be the latest permissible date
as outlined above. For Qualified Contracts, the Owner may be limited by the
plan under which the Contract is issued. In general, the Payout Start Date for
a Qualified Contract is:
 
 . April 1st of the calendar year following the year in which the Annuitant
   reaches age 70 1/2 if the Annuitant's age on the Issue Date is less than 70
   1/2;
 
                                       10
<PAGE>
 
 . April 1st of the year following issue if the Annuitant's age at any time
   during the calendar year in which the Contract is issued is equal to 70
   1/2; or
 . December 31st of the year following issue if the Annuitant's age at all
   times during the calendar year in which the Contract is issued is greater
   than 70 1/2.
 
24. WHAT TYPES OF INCOME PLANS ARE AVAILABLE IN THE CONTRACT?
 
Income Payments are made under an Income Plan which may be chosen by the Owner.
The types of Income Plans which are available are as follows:
 
 . Life income with or without guaranteed payments. If the Annuitant dies
   before all the guaranteed payments have been made, the remainder of the
   guaranteed payments will be made to the Owner; or
 . Joint and survivor life income with or without guaranteed payments. If both
   the Annuitant and Joint Annuitant die before the guaranteed payments have
   been made, the remainder of the guaranteed payments will be made to the
   Owner; or
 . Guaranteed payments for a specified period. Payments under this option do
   not depend on the continuation of the Annuitant's life.
 
Any period for which payments are guaranteed may range from 60 to 360 months.
If any Owner dies, guaranteed Income Payments will continue as scheduled. 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's or Joint Annuitant's
life, proof of age will be required before Income Payments begin. The Company
reserves the right to accept other Income Plans.
 
25. HOW ARE THE INCOME PAYMENTS FROM AN INCOME PLAN DETERMINED?
 
To determine the Income Payments, the Adjusted Account Value will be applied to
the greater of:
 
 . payment plan rates declared by the Company; or
 . guaranteed payment plan rates as described in the Contract.
 
If the Adjusted Account Value is less than $2000, or if the monthly Income
Payments determined under the Income Plan are less than $20, the Company may
pay the Adjusted Account Value in a lump sum or change the payment frequency to
an interval which results in Income Payments of at least $20.
 
The Contracts are based on life annuity 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 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 Contracts.
 
The dollar amount of Income Payments is generally affected by the duration of
the Income Plan selected. For example, if an Income Plan guaranteed for life is
chosen, the Income Payments may be greater or less than Income Payments under
an Income Plan for a specified period depending on the life expectancy of the
Annuitant. Also, 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.
 
26. CAN PARTIAL WITHDRAWALS BE TAKEN FROM THE CONTRACT OR CAN THE CONTRACT BE
SURRENDERED ONCE IT HAS ENTERED THE PAYOUT PHASE?
 
No. After the Adjusted Account Value has been applied to an Income Plan on the
Payout Start Date, the Income Plan can not be changed, the exchange of the
Adjusted Account Value for an Income Plan can not be reversed, and no
withdrawals can be made.
 
                                       11

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 Agents' Agreement
with the Company.
   
Dean Witter is a wholly-owned subsidiary of Dean Witter, Discover & Co. ("Dean
Witter Discover"). Dean Witter is located at Two World Trade Center, New York,
New York. Dean Witter is a member of the New York Stock Exchange and the
National Association of Securities Dealers.     
 
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. In addition, sale of the
Contract may count toward incentive program awards for the Account Executive.
 
The General Agents' 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.
 
FEDERAL TAX MATTERS
 
INTRODUCTION
 
The Contract was designed for use by individuals in retirement plans which may
or may not be plans qualified for special tax treatment under Section 401, 403,
408, or 457 of the Internal Revenue Code ("Code"). The ultimate effect of
federal income taxes on the Account Value, on Income Payments and on the
economic benefit to the Owner, the Annuitant or the Beneficiary depends on the
type of retirement plan for which the Contract is purchased, on the tax and
employment status of the individual concerned and on the Company's tax status.
THE TAX DISCUSSION BELOW IS GENERAL AND IS NOT INTENDED AS TAX ADVICE. Any
person concerned about these tax implications should consult a competent tax
adviser. This discussion is based upon the Company's understanding of the
present federal income tax laws as they are currently interpreted by the
Internal Revenue Service. No representation is made as to the likelihood of
continuation of these present federal income tax laws or of the current
interpretations by the Internal Revenue Service. Moreover, no attempt has been
made to consider any applicable state or other tax laws.
 
TAXATION OF THE COMPANY
 
The Company is taxed as a life insurance company under Part I of Subchapter L
of the Code. The following discussion assumes that the Company will continue to
be taxed as a life insurance company under Part I of Subchapter L.
 
TAXATION OF ANNUITIES IN GENERAL
 
The following discussion assumes that the Contract will qualify as an annuity
contract for federal income tax purposes. Such qualifications are discussed
below.
 
Generally, an annuity contract owner who is a natural person is not taxed on
increases in the Account Value until a distribution occurs. For federal income
tax purposes, distributions include the receipt of proceeds from loans and an
assignment or pledge of any portion of the value of the Contract, as well as
withdrawals, Income Payments, or Death Benefits. The exception to this rule is
that Owners who are not natural persons generally must include in income any
increase during the taxable year in the Account Value (once the Account Value
exceeds the investment in the Contract). However, there are exceptions to this
non-natural owner rule and you should discuss these with your tax adviser. The
following discussion only applies to Contracts owned by natural persons.
 
Generally, in the case of a surrender, withdrawal, loan, assignment or pledge
under a Non-Qualified Contract before the Payout Start Date, amounts received
are first treated as taxable income to the extent that the Account Value of the
Contract immediately before the surrender exceeds the
                                       12
<PAGE>
 
   
"investment in the contract" (as defined in the Code) at that time. Any
additional amount is not taxable. The Account Value is the sum of all Sub-
Account values. No matter which Sub-Account a withdrawal is made from, all Sub-
Account values are combined and the Account Value is used to determine the
amount of taxable income.     
 
The recipient of periodic Income Payments under the Contract is, in general,
taxed on a portion of each payment. Generally, for Income Payments (prior to
recovery of the investment in the Contract), there is no tax on the amount of
each payment which represents the same ratio that the "investment in the
contract" bears to the total expected value of the Income Payments for the term
of the payments; however, the remainder of each Income Payment is taxable.
After the Owner's investment in the Contract has been recovered, the full
amount of any additional payments will be taxed.
 
The taxable portion of a distribution (in the form of an Income Payment or a
lump sum payment) is taxed as ordinary income.
   
Premature distributions from Non-Qualified Contracts may be subject to a
penalty equal to ten percent (10%) of the amount treated as taxable income. The
penalty applies to the taxable portion of any distribution except those (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) received in substantially equal installments
as a life annuity or over a period not exceeding the life expectancy of the
owner; or (4) allocable to investments in the Contract prior to August 14,
1982. NOTE: the penalty may apply to a distribution received which results from
the death of an Annuitant who is not also an Owner. Other tax penalties may
apply to certain distributions under Qualified Contracts.     
 
All Non-Qualified deferred annuity contracts that are 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 amount
includable in gross income under section 72(e) of the Code. Accordingly, an
Owner should consult a competent tax adviser when purchasing more than one Non-
Qualified Deferred Annuity Contract in one calendar year.
 
Transfer of ownership of a Contract, the designation of an Annuitant or a
Beneficiary who is not also the Owner, or the exchange of a Contract may result
in certain tax consequences to the Owner that are not discussed herein. An
Owner contemplating any such transfer, assignment, or exchange of a Contract
should contact a competent tax adviser with respect to the potential tax
effects of such a transaction.
 
In order to be treated as an annuity contract for federal income tax purposes,
Section 72(s) of the Code requires any Non-Qualified Contract issued after
January 18, 1985 to provide that (a) if any Owner dies on or after the Payout
Start Date but prior to the time the entire interest in the Contract has been
distributed, the remaining portion of such interest will be distributed at
least as rapidly under the method of distribution being used as of the date of
that Owner's death; and (b) if any Owner dies prior to the Payout Start Date,
the entire interest in the Contract will be distributed within five years after
the date of the Owner's death. These requirements shall be considered satisfied
with respect to any portion of the Owner's interest which is payable to, or for
the benefit of, a "designated beneficiary," if such portion is distributed over
the life of such "designated beneficiary" or over a period not extending beyond
the life expectancy of that Beneficiary and such distributions begin within one
year of that Owner's death. The Owner's "designated beneficiary" is the
surviving Owner(s) or the person(s) designated by such Owner as a Beneficiary.
The "designated beneficiary" is the person to whom ownership of the Contract
passes by reason of 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.
 
Non-Qualified Contracts contain provisions which are intended to comply with
the requirements of section 72(s) of the Code, although regulations
interpreting these requirements have not yet been issued. The Company intends
to review such provisions and modify them if necessary to assure that they
comply with the requirements of Code Section 72(s) when clarified by regulation
or otherwise.
 
Other rules may apply to Qualified Contracts.

QUALIFIED PLANS
 
The Contract is designed for use 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 in itself. Adverse tax
consequences may result from contributions in excess of specified limits,
distributions prior to age 59 1/2, distributions that do not conform to
specified commencement and minimum distribution rules, aggregate distributions
in excess of a specified annual amount and in other circumstances. Therefore,
the Company makes no attempt to provide more than general information about the
use of the Contracts with the various types of qualified plans. Owners and
participants under qualified plans as well as Annuitants and Beneficiaries are
cautioned that the rights of any person to any benefits under qualified plans
may be subject to the terms and conditions of the plans themselves regardless
of the terms and conditions of the Contract issued in connection therewith.
Purchasers of the Contracts for use with any qualified plan should seek
competent advice regarding the suitability of the Contract.
 
(a) Section 403(b) Plans. Under Section 403(b) of the Code, payments made by
public school systems and certain not-for-profit organizations to purchase
annuity contracts for their employees are excludable from the gross income of
the employee, subject to certain limitations. In accordance with the
requirements of Section 403(b), any contract used for a Section 403(b) Plan
will prohibit distributions of (i) elective contributions made in years
beginning after December 31, 1988, (ii) earnings on those contributions, and
(iii) earnings on amounts attributable to elective contributions held as of the
end of the last year beginning before January 1, 1989. However, distributions
of such amounts will be allowed upon death of an employee, attainment of age 59
1/2, separation from service, disability, or financial hardship, except that
income attributable to elective contributions may not be distributed in the
case of hardship.
 
(b) H.R. 10 Plans. The Self-Employed Individuals Tax Retirement Act of 1962, as
amended, commonly referred to as "H.R. 10" or "Keogh," permits self-employed
individuals to establish qualified plans for themselves and their employees.
These plans are limited by law to maximum permissible contributions,
distribution dates, and nonforfeitability of interests. In order to establish
such a plan, a plan document, usually in a form approved in advance by the
Internal Revenue Service, is adopted and implemented by the employer.
 
(c) Individual Retirement Annuities. Sections 219 and 408 of the Code permit
individuals or their employers to contribute to an individual retirement
program known as an "Individual Retirement Annuity." Individual Retirement
Annuities are subject to limitations on the amount which may be contributed and
on the time when distribution may commence. In addition, distributions from
certain other types of qualified plans may be placed into an Individual
Retirement Annuity on a tax-deferred basis.
 
(d) Corporate Pension and Profit-Sharing Plans. Sections 401(a) and 403(a) of
the Code permit corporate employers to establish various types of retirement
plans for employees. Such retirement plans may permit the purchase of the
Contracts to provide benefits under the plans.
   
(e) State and Local Governments Deferred Compensation Plans. Section 457 of the
Code, while not actually providing for a qualified plan as that term is
normally used, provides for certain Deferred Compensation Plans with respect to
service to state governments, local governments, political subdivisions,
agencies, instrumentalities and certain affiliates of such entities and certain
tax exempt organizations which enjoy special treatment. Under such plans a
participant may specify the form of investment in which his or her
participation will be made. All such investments, however, are owned by and
subject to the claims of general creditors of the sponsoring employer.     
 
OTHER CONSIDERATIONS
 
The Company is required to withhold federal income tax at a rate of 20% on all
distributions which constitute "eligible rollover distributions," unless the
recipient elects to rollover such amounts to another qualified plan or IRA in a
direct rollover. Eligible rollover distributions generally include all
distributions from qualified plans, excluding IRA's and 457 plans, with the
exception
 
                                       14
<PAGE>
 
of (1) minimum distributions pursuant to Section 401(a)(9), and (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 beneficiaries). In addition,
some states require that state income tax be withheld.
 
For any distributions which do not constitute "eligible rollover
distributions," the Company is required to withhold federal and, where
required, state income taxes on all distributions, unless the recipient elects
not to have taxes withheld and properly notifies the Company of that election.
 
The foregoing comments about the federal tax consequences under these Contracts
are not exhaustive, and special rules are provided with respect to other tax
situations not discussed in this prospectus. Before making an investment, a
qualified tax adviser should be consulted. Further, the federal income tax
consequences discussed herein reflect current law.
 
Federal estate, state and local estate, inheritance, and other tax consequences
of ownership or receipt of distributions under a Contract depend on the
individual circumstances of each Owner or recipient of the distribution. A
competent tax adviser should be consulted for further information.
 
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's products, group and
individual annuities and life insurance, have been approved by the various
states where offered.
   
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, 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"). In June 1995, Sears, Roebuck and Co. distributed in a tax-free
dividend to its stockholders its 80.3% ownership interest of the Corporation.
    
REINSURANCE AGREEMENTS
   
The Company and Allstate Life entered into a reinsurance agreement, effective
December 31, 1987, under which the Company automatically reinsures
substantially all of its fixed annuity business, with the exception of certain
Qualified Contracts (as discussed in the following paragraph), with Allstate
Life. Under the reinsurance agreement, Purchase Payments under general account
contracts 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. (See, "Management's Discussion and Analysis of
Financial Condition and Results of Operations", pg. 18). However, the
obligations of Allstate Life under the reinsurance agreement are to the
Company; the Company remains the sole obligor under the Contracts of 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 assets 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.     
   
Purchase Payments of Qualified Contracts issued in conjunction with a Section
401(a), 401(k) or 403(b) plan, will be invested in the general account of the
Company. The Company and Allstate Life have entered into a modified coinsurance
agreement under which Allstate Life will continue to reinsure all of the
Company's general account obligations under such Qualified Contracts; the
reserves for such Qualified Contracts will be held in the Company's general
account and, therefore,     
                                        15
<PAGE>
 
   
will not be subject to the trust arrangement described above.     
 
INVESTMENTS BY THE COMPANY
 
The Company's general account assets, like the general account assets of other
insurance companies including Allstate Life, 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 facilitate 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.

NORTHBROOK LIFE INSURANCE COMPANY MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS     
   
The following highlights significant factors influencing results of operations
and financial position.     
   
Northbrook Life Insurance Company ("the Company"), which is wholly owned by
Allstate Life Insurance Company ("Allstate Life"), issues single and flexible
premium fixed annuity contracts and universal life insurance policies. In
addition, the Company issues flexible premium deferred variable annuity
contracts, the assets and liabilities of which are legally segregated and
reflected in the accompanying statements of financial position as the assets
and liabilities of the Separate Accounts. Dean Witter Reynolds is the sole
distributor of the Company's products and also manages the funds in which the
assets of the Separate Accounts are invested.     
   
The Company reinsures substantially all of its annuity deposits and life
insurance in force with Allstate Life. 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 under the reinsurance treaties.     
   
Variable annuity assets and liabilities are carried at fair value in the
statements of financial position. Investment income and realized gains and
losses of the Separate Account investments accrue directly to the
contractholders (net of fees) and, therefore, are not included in the Company's
statements of operations.

</TABLE>    
   
In 1995, net investment income increased $1.9 million. This increase related to
an increased level of investments which resulted from a $25 million     
   
capital contribution from Allstate Life during December 1994. Net investment
income decreased in 1994 over 1993, primarily due to slightly lower portfolio
yields, partially offset by the increase in investments during the year.     
   
Realized capital gains after tax were $44 thousand in 1995 compared to capital
losses of $125 thousand in 1994. Overall, the market values of fixed income
securities were higher in 1995 than in 1994, which resulted in gains in 1995
and losses in 1994 when certain fixed income securities were sold in response
to changes in market conditions.     
   
Net income increased $1.4 million in 1995 reflecting the increase in net
investment income and realized capital gains. The $0.8 million decrease in 1994
from 1993 is primarily attributable to increased realized capital losses and a
higher effective income tax rate in 1994.

</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 $4.1 million compared to an
unrealized capital loss of $2.4 million at December 31, 1994. The significant
change in the unrealized capital gain/loss position is primarily attributable
to declining interest rates.     
 
                                       18
<PAGE>
       
   
Contractholder funds decreased by $453 million and reinsurance recoverable from
Allstate Life under reinsurance treaties decreased by $449     
   
million, reflecting policyholder transfers from fixed annuities to variable
annuities and fixed annuity surrenders. Reinsurance recoverable from Allstate
Life relates to policy benefit obligations ceded to Allstate Life.     
   
Separate Accounts increased by $750 million attributable to sales of variable
annuities, the favorable investment performance of the Separate Account funds,
and the policyholder transfers previously described.     
   
LIQUIDITY AND CAPITAL RESOURCES     
   
In December 1994, Allstate Life made a $25 million capital contribution to the
Company.     
   
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 who maintains the 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 Aa3 (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, 1995, Northbrook Life has approximately 178 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 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 NORTHBROOK LIFE INSURANCE COMPANY:
   
  We have audited the accompanying Statements of Financial Position of
Northbrook Life Insurance 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 Northbrook Life Insurance 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 investment in fixed income securities.

1. ORGANIZATION AND NATURE OF OPERATIONS
 
  Northbrook Life Insurance 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 single and flexible premium annuities and
flexible premium deferred and variable annuity contracts to individuals in the
United States through Dean Witter Reynolds ("Dean Witter")(Note 4). Other
products include universal life and single premium life insurance.
   
  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 federal
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 writes long-duration insurance contracts with terms that are not
fixed and guaranteed and single premium life insurance contracts, which are
considered universal life-type contracts. The Company also sells long-duration
contracts that do not involve significant risk of policyholder mortality or
 
                                      F-6

                NOTES TO FINANCIAL STATEMENTS--(CONTINUED)     
                                
                             ($ IN THOUSANDS)     
morbidity (principally single and flexible premium annuities, structured
settlement annuities and supplemental contracts when sold without life
contingencies) which are considered investment contracts. Limited payment
contracts (policies with premiums paid over a period shorter than the contract
period), primarily consist of structured settlement annuities and supplemental
contracts when sold with life contingencies.
 
   TRADITIONAL LIFE
 
    The reserve for life insurance policy benefits, which relates to
  structured settlement annuities and supplementary contracts when sold with
  life contingencies, is computed on the basis of assumptions as to future
  investment yields, mortality, morbidity, terminations and expenses. These
  assumptions, which for traditional life are applied using the net level
  premium method, include provisions for adverse deviation and generally vary
  by such characteristics as plan, year of issue and policy duration. Reserve
  interest rates ranged from 7.3% to 9.5% during 1995.
 
   UNIVERSAL LIFE-TYPE CONTRACTS
 
    Reserves for universal life-type contracts are established using the
  retrospective deposit method. Under this method, liabilities are equal to
  the account balance that accrues to the benefit of the policyholder.
 
   CONTRACTHOLDER FUNDS
 
    Contractholder funds arise from the issuance of individual contracts that
  include an investment component, including universal life-type contracts.
  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. During 1995, credited interest rates on
  contractholder funds ranged from 3.0% to 8.0% for those contracts with
  fixed interest rates and from 3.0% to 8.7% for those with flexible rates.
 
 SEPARATE ACCOUNTS
   
  The Company issues flexible premium deferred variable annuity contracts, the
assets and liabilities of which are legally segregated and reflected in the
accompanying statements of financial position as assets and liabilities of the
Separate Accounts. Assets and liabilities of the Separate Accounts represent
funds of Northbrook Variable Annuity Account and Northbrook Variable Annuity
Account II ("Separate Accounts"), unit investment trusts registered with the
Securities and Exchange Commission. The assets of the Separate Accounts are
carried at fair value. Investment income and realized gains and losses of the
Separate Accounts 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.

 REINSURANCE
 
  Premiums, contract charges, credited interest, and policy benefits are ceded
and reflected net of such cessions in the statements of operations. Reinsurance
recoverable and the related reserves for policy benefits 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 component
of shareholder's equity. Provisions are made to write down the 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.
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 $747, with no impact on
net income.

4. RELATED PARTY TRANSACTIONS
 
 REINSURANCE
   
  The Company reinsures substantially all business with Allstate Life. Premiums
and contract charges ceded to Allstate Life were $2,284 and $52,348 in 1995,
$1,886 and $38,306 in 1994, and $2,688 and $22,446 in 1993. Credited interest,
policy benefits and other expenses ceded to Allstate Life amounted to $229,525,
$243,326, and $525,467 in 1995, 1994, and 1993, respectively. Investment income
earned on the assets which support contractholder funds was excluded from the
Company's financial statements as those assets were transferred to Allstate
Life under the terms of reinsurance treaties. Reinsurance ceded arrangements do
not discharge the Company as the primary insurer.     
 
 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. 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 $5,341, $5,483 and $5,301 in 1995, 1994 and 1993, respectively.
Investment-related expenses are retained by the Company. All other costs are
assumed by Allstate Life under reinsurance agreements.     
 
 DEAN WITTER
   
  The Company and Allstate Life have formed 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.
    
  Under the terms of the strategic alliance, which is cancelable by either
party, the Company has agreed to use Dean Witter as an exclusive distribution
channel for the Company's products. Dean Witter is also the investment manager
for the Dean Witter Variable Investment Series, the fund in which the assets of
the Separate Accounts are invested.
 
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

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, foreign tax credits, 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.

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 assets and liabilities of
the Separate Accounts are carried at the fair value of the funds in which the
assets are invested. 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 related to 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 and annuities without life contingencies with
fixed terms are estimated using discounted cash flow calculations based on
interest rates currently offered for contracts with similar terms and duration.
Contractholder funds on investment contracts had a carrying value of $2,294,536
at December 31, 1995 and a fair value of $2,274,053. The carrying value and
fair value at December 31, 1994 were $2,738,823 and $2,685,448, respectively.

 PERMITTED STATUTORY ACCOUNTING PRACTICES
   
  The Company prepares its 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 $7,057.

                            MARKET VALUE ADJUSTMENT
 
  The Market Value Adjustment is based on the following:
 
  I=   the X-year Treasury Rate for the week preceding the issue date of the
       Certificate, where X is the Sub-Account guarantee period chosen. If a
       Note with a maturity of X years is not available, a weighted average
       will be used.
 
  N=   the number of complete days from the date we receive the withdrawal
       request to the end of the Xth year since the Sub-Account was
       established.
 
  J=   the Treasury Rate for a maturity of N days for the week preceding the
       receipt of the withdrawal request. If a Note with a maturity of N days
       is not available, a weighted average will be used. If N is one year or
       less, J will be the 1-year Treasury Rate.
 
  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 (1.0625)/3/ = $11,994.63
 
Step 2: Calculate The Amount Withdrawn in Excess of the Free Withdrawal Amount:
 
Amount Withdrawn: 11,994.63
Free Withdrawal Amount: .10 X 10,000.00 = 1,000.00
Amount Withdrawn in Excess of the Free Withdrawal Amount:
                           = 11,994.63- 1,000.00 = $10,994.63
 
 
                                      A-1
<PAGE>
 
Step 3: Calculate the Withdrawal Charge:
 
                           = .06 X 10,994.63 = $659.68
 
Step 4: Calculate the Market Value Adjustment:
I= 6.25%
J= 5.95%
N = 730 days
 
Market Value Adjustment Factor: .9 X (I-J) X (N/365)
                           = .9 X (.0625 - .0595) X (730/365) = .0054
 
Market Value Adjustment = Factor X Amount in Excess of Free Withdrawal Amount:
                           = .0054 X 10,994.63 = $59.37
 
Step 5: Calculate The Net Surrender Value at End of Contract Year 3:
                           = 11,994.63 - 659.68 + 59.37 = $11,394.32
 
EXAMPLE 2: (Assumes rising interest rates)
 
Step 1: Calculate Account Value at End of Contract Year 3:
                           = 10,000.00 X (1.0625)/3/ = $11,994.63
 
Step 2: Calculate The Amount Withdrawn in Excess of the Free Withdrawal Amount:
 
Amount Withdrawn: 11,994.63
Free Withdrawal Amount: .10 X 10,000.00 = 1,000.00
Amount Withdrawn in Excess of the Free Withdrawal Amount:
                           = 11,994.63 - 1,000.00 = $10,994.63
 
Step 3: Calculate the Withdrawal Charge:
                           = .06 X 10,994.63 = $659.68
 
Step 4: Calculate the Market Value Adjustment:
I= 6.25%
J= 6.55%
N = 730 days
 
Market Value Adjustment Factor: .9 X (I-J) X (N/365)
                           = .9 X (.0625 - .0655) X (730/365) = -.0054
 
Market Value Adjustment = Factor X Amount in Excess of Free Withdrawal Amount:
                           = -.0054 X 10,994.63 = -$59.37
 
Step 5: Calculate The Net Surrender Value at End of Contract Year 3:
                           = 11,994.63 - 659.68 - 59.37 = $11,275.58

ITEM 13.  Other Expenses of Issuance and Distribution.

          Pursuant to Item 511 of Regulation S-K, the Registrant hereby
          represents that the following expenses totaling approximately $126,707
          will be incurred or are anticipated to be incurred in connection with
          the issuance and distribution of the securities to be registered:
          registration fees - $86,207; cost of printing and engraving - $35,000;

ITEM 17.  Undertakings.

          The undersigned registrant, Northbrook Life Insurance Company, hereby
undertakes:

          (1)  To file, during any period in which offers or sales are being
               made, a post-effective amendment to this registration statement:
    
               (i)    To include any prospectus required by section 10(a)(3) of
                      the Securities Act of 1933;     

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

               (iii)  To include any material information with respect to the
                      plan of distribution not previously disclosed in the
                      registration statement or any material change to such
                      information in the registration statement;
    
          (2)  That, for the purpose of determining any liability under the
               Securities Act of 1933, each such post-effective amendment shall
               be deemed to be a new registration statement relating to the
               securities offered therein, and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof;      

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