NORTHWESTERN MUTUAL VARIABLE LIFE

     -    WHOLE LIFE
     -    EXTRA ORDINARY LIFE
     -    SINGLE PREMIUM LIFE

This prospectus describes three variable life insurance policies (the
"Policies") issued by The Northwestern Mutual Life Insurance Company: Whole
Life, Extra Ordinary Life and Single Premium Life. Each Policy is designed to
provide lifetime insurance coverage on the insured named in the Policy. A Policy
may also be surrendered for its cash value during the lifetime of the insured.
The death benefit and cash value of a Policy will vary to reflect the investment
experience of Northwestern Mutual Variable Life Account (the "Account").

The owner of a Policy may allocate the net premiums to one or more of the nine
divisions of the Account. The assets of each division will be invested in a
corresponding Portfolio of Northwestern Mutual Series Fund, Inc. (the "Fund").
The prospectus for the Fund, attached to this prospectus, describes the
investment objectives of the nine Portfolios: the Aggressive Growth Stock
Portfolio, International Equity Portfolio, Growth Stock Portfolio, Growth and
Income Stock Portfolio, Index 500 Stock Portfolio, Balanced Portfolio, High
Yield Bond Portfolio, Select Bond Portfolio and Money Market Portfolio.

Northwestern Mutual Life guarantees that the death benefit for a Whole Life
Policy will never be less than the face amount of the Policy, regardless of the
Account's investment experience, so long as premiums are paid when due and no
Policy debt is outstanding. For an Extra Ordinary Life Policy, the death benefit
will never be less than the Minimum Death Benefit stated in the Policy, so long
as premiums are paid when due and no Policy debt is outstanding. The Extra
Ordinary Life Policy is designed for purchasers who intend to use all Policy
dividends to purchase paid-up additions. For a Single Premium Life Policy, the
death benefit will never be less than the face amount of the Policy, if no
Policy debt is outstanding. There is no guaranteed minimum cash value for any of
the three Policies.

In the early years of a Policy it is likely that the cash value will be less
than the premium amounts accumulated at interest. This is because of the sales
and issuance costs for a new Policy. For a Whole Life Policy or an Extra
Ordinary Life Policy deductions for sales costs are made from premiums. These
deductions are higher during the early Policy years. For a Single Premium Life
Policy deductions for sales costs are made from the cash values of Policies
surrendered during the early Policy years. Therefore a Policy should be
purchased only if the purchaser intends to keep it in force for a reasonably
long period.

   
A policy may be returned for a full refund for a limited period of time. See
"Right to Return Policy", p. 15.

THE PRIMARY PURPOSE OF THESE VARIABLE LIFE INSURANCE POLICIES IS TO PROVIDE
INSURANCE PROTECTION.  NO CLAIM IS MADE THAT THE POLICIES ARE IN ANY WAY SIMILAR
OR COMPARABLE TO A SYSTEMATIC INVESTMENT PLAN OF A MUTUAL FUND.

- --------------------------------------------------------------------------------
SUMMARY OF THE POLICIES


VARIABLE LIFE INSURANCE

Variable life insurance is similar in many ways to traditional fixed-benefit
whole life insurance. There are also significant differences. For both fixed and
variable insurance the owner of the policy pays level premiums for lifetime
insurance coverage on the person insured. Both kinds of insurance provide a cash
value payable upon surrender of the policy during the insured's lifetime. In
each case the cash value during the early years is ordinarily less than the sum
of the premiums paid. Various optional benefits may be added to either kind of
policy (except single premium policies) at extra cost.

The distinctive feature of the variable Policies described in this prospectus is
that the premiums, after certain deductions, are placed in one or more divisions
of Northwestern Mutual Variable Life Account. The death benefit and cash value
of the Policy will increase or decrease to reflect the investment performance of
the division or divisions selected. The death benefit is adjusted annually on
the Policy anniversary. Northwestern Mutual Life guarantees that the death
benefit for a Whole Life Policy will never be less than the face amount of the
Policy, so long as premiums are paid when due and no Policy debt is outstanding.
For an Extra Ordinary Life Policy, Northwestern Mutual Life guarantees that the
death benefit will never be less than the Minimum Death Benefit stated in the
Policy, so long as premiums are paid when due and no Policy debt is outstanding.
The Extra Ordinary Life Policy is designed for purchasers who intend to use all
Policy dividends to purchase paid-up additions. For a Single Premium Life
Policy, Northwestern Mutual Life guarantees that the death benefit will never be
less than the face amount of the Policy, if no policy debt is outstanding. For
all of the Policies, the cash value is adjusted daily. There is no guaranteed
minimum cash value.

THE ACCOUNT AND ITS DIVISIONS

   
The Account has nine divisions. The owner of the Policy determines how the net
annual premium is to be apportioned. The assets of each division are invested in
a corresponding Portfolio of Northwestern Mutual Series Fund, Inc. The nine
Portfolios are the Aggressive Growth Stock Portfolio, International Equity
Portfolio, Growth Stock Portfolio, Growth and Income Stock Portfolio, Index 500
Stock Portfolio, Balanced Portfolio, High Yield Bond Portfolio, Select Bond
Portfolio and Money Market Portfolio. The investment objectives of the
Portfolios are briefly described herein. See "The Fund", p. 4.  For additional
information see the attached prospectus for the Fund.
    

DEDUCTIONS AND CHARGES

The net annual premium for a Whole Life Policy and an Extra Ordinary Life Policy
is placed in the Account when the Policy is issued and on the Policy anniversary
each year. This amount is the total premium after deductions for sales and
administrative expenses, state premium taxes and risk charges. For an Extra
Ordinary Life Policy, a deduction is also made for dividends to be paid or
credited in accordance with the dividend scale in effect on the issue date of
the Policy. For the first year there is also a fixed fee for expenses incurred
in issuing the Policy. The net annual premium excludes any extra premium charged
for insureds who do not qualify as select risks and the extra premium for
optional benefits.

For a Single Premium Life Policy an administrative charge of $l50 is made when
the Policy is issued. This is the only deduction from the single premium, but if
a Single Premium Policy is surrendered during the first ten policy years the
cash value payable on surrender is reduced by a deduction for sales costs.

The Account pays a charge at the annual rate of .50% of the Account's assets for
the mortality and expense risks assumed by Northwestern Mutual Life and a charge
at the annual rate of .20% of the Account's assets for federal income taxes
incurred by Northwestern Mutual Life. The Fund pays an investment advisory fee,
and other expenses, which vary depending on the Portfolios selected.

   
For additional information, see "Deductions and Charges", p. 7.
    

For a Whole Life Policy or an Extra Ordinary Life Policy the deductions in the
first year for sales and administrative expenses will often amount to more than
50% of the total annual premium. The percentage varies with the age of the
insured and the size of the Policy. For Whole Life Policies the percentage
ranges from 40% for large Policies at the highest ages to 90% for the smallest
Policies for juveniles. For Extra Ordinary Life Policies the percentage ranges
from 54% for large Policies at the highest ages to 87% for the smallest Policies
for juveniles.

OTHER INFORMATION

For a Whole Life Policy the minimum face amount of insurance for which a Policy
may be issued is $20,000. If the insured is below age 15 or over age 49, the
minimum amount is $10,000. The insured may not be older than age 70 on the date
of issue. For an Extra Ordinary Life Policy the minimum initial amount of
insurance for which a Policy may be issued is $50,000; if the insured is over
age 70, the minimum amount is $25,000. The minimum face amount of insurance for
which a Single Premium Life Policy may be issued is $5,000. For an Extra
Ordinary Life Policy the insured may not be younger than age l5 on the date of
issue. For either an Extra Ordinary Life Policy or a Single Premium Life Policy
the insured may not be older than age 75 on the date of issue.

   
For a limited time a Policy may be returned for a refund. See "Right to Return
Policy", p. 15.

THE NORTHWESTERN MUTUAL LIFE INSURANCE COMPANY,
NORTHWESTERN MUTUAL VARIABLE LIFE ACCOUNT AND
NORTHWESTERN MUTUAL SERIES FUND, INC.

NORTHWESTERN MUTUAL LIFE

   
The Northwestern Mutual Life Insurance Company is a mutual life insurance
company organized by a special act of the Wisconsin Legislature in 1857. It is
the nation's fifth largest life insurance company, based on total assets in
excess of $71 billion on December 31, 1997 and is licensed to conduct a
conventional life insurance business in the District of Columbia and in all
states of the United States. Northwestern Mutual Life sells life and disability
income insurance policies and annuity contracts through its own field force of
approximately 6,000 full time producing agents.
    

THE ACCOUNT

Northwestern Mutual Variable Life Account was established by the Trustees of
Northwestern Mutual Life on November 23, 1983, in accordance with the provisions
of Wisconsin insurance law. Under Wisconsin law the income, gains and losses,
realized or unrealized, of the Account are credited to or charged against the
assets of the Account without regard to other income, gains or losses of
Northwestern Mutual Life. The Account is used only for the variable life
insurance Policies.

The Account is registered as a unit investment trust under the Investment
Company Act of 1940. Such registration does not involve supervision of
management or investment practices or policies. The Account has nine divisions.
All of the assets of each division are invested in shares of the corresponding
Portfolio of the Fund described below.

THE FUND

Northwestern Mutual Series Fund, Inc. is a mutual fund of the series type
registered under the Investment Company Act of 1940 as an open-end diversified
management investment company. Shares of each Portfolio of the Fund are
purchased by the corresponding division of the Account at their net asset value
without any sales charge.

   
The investment adviser for the Fund is Northwestern Mutual Investment Services,
Inc. ("NMIS"), a wholly-owned subsidiary of Northwestern Mutual Life. The
investment advisory agreements for the respective Portfolios provide that NMIS
will provide services and bear certain expenses of the Fund. For providing
investment advisory and other services and bearing Fund expenses, the Fund pays
NMIS a fee at an annual rate which ranges from .20% of the aggregate average
daily net assets of the Index 500 Stock Portfolio to a maximum of .67% for the
International Equity Portfolio, based on 1997 asset size.  Other expenses borne
by the Portfolios range from 0% for the Select Bond, Money Market and Balanced
Portfolios to .10% for the International Equity Portfolio. Northwestern Mutual
Life provides certain personnel and facilities used by NMIS in performing its
investment advisory functions and is a party to the investment advisory
agreement.  J.P. Morgan Investment Management, Inc. and Templeton Investment
Counsel, Inc. have been retained under investment sub-advisory agreements to
provide investment advice to the Growth and Income Stock Portfolio and the
International Equity Portfolio, respectively.
    

The investment objectives and types of investments for each of the nine
Portfolios of the Fund are set forth below. There can be no assurance that the
objectives of the Portfolios will be realized. For more information about the
investment objectives and policies, the attendant risk factors and expenses see
the Fund prospectus.

AGGRESSIVE GROWTH STOCK PORTFOLIO.  The investment objective of the Aggressive
Growth Stock Portfolio is to achieve long-term appreciation of capital primarily
by investing in the common stocks of companies which can reasonably be expected
to increase their sales and earnings at a pace which will exceed the growth rate
of the nation's economy over an extended period.

INTERNATIONAL EQUITY PORTFOLIO.  The investment objective of the International
Equity Portfolio is long-term capital growth.  It pursues its objective through
a flexible policy of investing in stocks and debt securities of companies and
governments outside the United States

GROWTH STOCK PORTFOLIO.  The investment objective of the Growth Stock Portfolio
is long-term growth of capital; current income is secondary.  The Portfolio will
seek to achieve this objective by selecting investments in companies which have
above average earnings growth potential.

GROWTH AND INCOME STOCK PORTFOLIO.  The investment objective of the Growth and
Income Stock Portfolio is long-term growth of capital and income.  Ordinarily
the Portfolio pursues its investment objectives by investing primarily in
dividend-paying common stock.

INDEX 500 STOCK PORTFOLIO. The investment objective of the Index 500 Stock
Portfolio is to achieve investment results that approximate the performance of
the Standard & Poor's 500 Composite Stock Price Index ("S&P 500 Index").  The
Portfolio will attempt to meet this objective by investing in stocks included in


                                          4
<PAGE>

the S&P 500 Index.  Stocks are generally more volatile than debt securities and
involve greater investment risks.

BALANCED PORTFOLIO. The investment objective of the Balanced Portfolio is to
realize as high a level of long-term total rate of return as is consistent with
prudent investment risk. The Balanced Portfolio will invest in common stocks and
other equity securities, bonds and money market instruments. Investment in the
Balanced Portfolio necessarily involves the risks inherent in stocks and debt
securities of varying maturities, including the risk that the Portfolio may
invest too much or too little of its assets in each type of security at any
particular time.

HIGH YIELD BOND PORTFOLIO.  The investment objective of the High Yield Bond
Portfolio is to achieve high current income and capital appreciation by
investing primarily in fixed income securities that are rated below investment
grade by the major rating agencies.

SELECT BOND PORTFOLIO. The primary investment objective of the Select Bond
Portfolio is to provide as high a level of long-term total rate of return as is
consistent with prudent investment risk. A secondary objective is to seek
preservation of shareholders' capital. The Select Bond Portfolio will invest
primarily in debt securities. The value of debt securities will tend to rise and
fall inversely with the rise and fall of interest rates.

MONEY MARKET PORTFOLIO. The investment objective of the Money Market Portfolio
is to realize maximum current income consistent with liquidity and stability of
capital. The Money Market Portfolio will invest in money market instruments and
other debt securities with maturities generally not exceeding one year. The
return produced by these securities will reflect fluctuations in short-term
interest rates.

DETAILED INFORMATION ABOUT THE POLICIES

REQUIREMENTS FOR INSURANCE

The minimum face amount for which a Whole Life Policy may be issued is $20,000.
If the insured is below age 15 or over age 49 the minimum amount is $10,000. The
insured may not be older than age 70 on the date of issue. For an Extra Ordinary
Life Policy the minimum initial amount of insurance for which a Policy may be
issued is $50,000; if the insured is over age 70, the minimum amount is $25,000.
The minimum face amount of insurance for which a Single Premium Life Policy may
be issued is $5,000. For an Extra Ordinary Life Policy the insured may not be
younger than age l5 on the date of issue. For the Extra Ordinary Life Policy and
the Single Premium Life Policy, the insured may not be older than age 75 on the
date of issue.

Before issuing a Policy, Northwestern Mutual Life will require satisfactory
evidence of insurability. Non-smokers who meet preferred underwriting
requirements are considered select risks.  A higher premium is charged for
insureds who do not qualify as select risks. The amount of additional premium
depends on the risk classification in which the insured is placed.  Nonsmokers
in the second best classification are considered standard plus risks.  The best
class of smokers are considered standard risks.

PREMIUMS

Payment of the first premium is required to put a Whole Life Policy or an Extra
Ordinary Life Policy in effect. Premiums are level, fixed and payable in advance
during the insured's lifetime on a monthly, quarterly, semiannual or annual
basis. The owner of a Policy may change the premium frequency. The change will
be effective when the premium on the new frequency is accepted. Premiums paid
more often than annually include an extra amount to compensate Northwestern
Mutual Life for the extra processing costs and loss of interest because the
money is received later. The amount of the premium depends on the amount of
insurance for which the Policy was issued and the insured's age and risk
classification. The amount of the premium also reflects the sex of the insured
except where state or federal law requires that premiums and other charges and
values be determined without regard to sex. A notice is sent to the owner of a
Policy not less than two weeks before each premium is due. If the monthly
premium frequency is selected, Northwestern Mutual Life may require that premium
payments be made by preauthorized check. 

The following table for Whole Life Policies shows representative premiums for
male select, standard plus, and standard risks for various face amounts of
insurance.

For a Single Premium Life Policy the purchaser may choose either a face amount
of insurance or the amount which a given amount of premium will provide. The
Single Premium Life Policy is available only for applicants who meet select or
standard plus underwriting criteria as determined by Northwestern Mutual Life.
The premiums for these Policies are the same for both select and standard plus
risks, but it is expected that the dividends will be lower for Policies issued
to insureds in the standard plus classification.

The following table for Single Premium Life Policies shows representative gross
single premiums for male select and standard plus risks for various face amounts
of Insurance:

GRACE PERIOD

For the Whole Life and Extra Ordinary Life Policies there is a grace period of
31 days for any premium that is not paid when due. The Policy remains in force
during this period. If the premium is not paid within the grace period the
Policy will terminate as of the date when the premium was due and will no longer
be in force, unless it is continued as extended term or


                                          6
<PAGE>

   
paid-up insurance. See "Extended Term and Paid-Up Insurance", p. 15. If a Policy
is surrendered, its cash value will be paid. See "Cash Value", p. 13. If the
insured dies during the grace period any overdue premium will be deducted from
the proceeds of the Policy. If the insured dies after payment of the premium for
the period which includes the date of death, the portion of the premium for the
remainder of that period will be refunded as part of the Policy proceeds.
    

ALLOCATIONS TO THE ACCOUNT

The net annual premium for a Whole Life Policy or an Extra Ordinary Life Policy
is placed in the Account on the Policy date and on the Policy anniversary each
year. The net annual premium is the annual premium less the deductions described
below.

The owner of a Whole Life or an Extra Ordinary Life Policy determines how the
net annual premium is apportioned among the divisions of the Account. If any
portion of a premium is directed to a division, the division must receive at
least 10% of that premium. The apportionment for future premiums may be changed
upon written request at any time, but the change will be effective only when the
net annual premium is placed in the Account on the next Policy anniversary, even
if premiums are being paid on an other than annual basis.

For a Single Premium Policy the entire single premium, less an administrative
charge of $150, is placed in the Account on the Policy date and apportioned
among the divisions of the Account as determined by the owner of the Policy.

The Account assets supporting a Policy may be apportioned among as many as six
divisions of the Account at any time.

TRANSFERS BETWEEN DIVISIONS

The owner of a Policy may transfer accumulated amounts from one division of the
Account to another as often as four times in a Policy year. Transfers are
effective on the date a written request is received at the Home Office of
Northwestern Mutual Life. Northwestern Mutual Life reserves the right to charge
a fee to cover administrative costs of transfers. No fee is presently charged.

DEDUCTIONS AND CHARGES

   
The net premiums placed in the Account for Whole Life, Extra Ordinary Life and
Single Premium Life Policies are the gross premiums after the deductions
described in the next two sections below. The net premiums for Whole Life and
Extra Ordinary Life Policies exclude any extra premium charged for insureds who
do not qualify as select risks and the extra premium for any optional benefits.
A charge for mortality and expense risks is made against the assets of the
Account. There is also a charge for taxes. See "Charges Against the Account
Assets", p. 9. In addition, the Fund in which the Account assets are invested
pays an investment advisory fee and certain other expenses. Fund expenses are
briefly described above on page 4, and in more detail in the attached prospectus
for the Fund.
    

DEDUCTIONS FROM PREMIUMS FOR WHOLE LIFE AND EXTRA ORDINARY LIFE POLICIES

The deductions described in this section are for Whole Life and Extra Ordinary
Life Policies only. The deductions for Single Premium Life Policies are
described under the next caption below.

For the first Policy year there is a one-time deduction of not more than $5 for
each $1,000 of insurance, based on the face amount for Whole Life or the Minimum
Death Benefit stated in the Policy for Extra Ordinary Life. This is for the
costs of processing applications, medical examinations, determining insurability
and establishing records.

There is an annual deduction of $35 for administrative costs to maintain the
Policy. Expenses include costs of premium billing and collection, processing
claims, keeping records and communicating with Policyowners.

There is a deduction each year for sales costs. This amount may be considered a
"sales load". The deduction will be not more than 30% of the basic premium (as
defined below) for the first Policy year, not more than 10% for each of the next
three years and not more than 7% each year thereafter. The basic premium for a
Policy is the gross premium which would be payable if the premium were paid
annually, less the annual deduction of $35 for administrative costs. The basic
premium is based on the cost of insurance for insureds who qualify as select
risks and does not include any extra premium amounts for insureds who are placed
in other risk classifications. The basic premium does not include the extra
premium for any optional benefits. For an Extra Ordinary Life Policy, the basic
premium does not include any extra premium for the Extra Life Protection; the
amount of term insurance included in the Extra Life Protection affects the
dividends payable on the Extra Ordinary Life Policies.

The amount of the deduction for sales costs for any Policy year is not
specifically related to sales costs incurred for that year. Northwestern Mutual
Life expects to recover its total sales expenses from the amounts deducted for
sales costs over the period while the Policies are in force. To the extent that
sales expenses exceed the amounts deducted, Northwestern Mutual Life will pay
the expenses from its other assets. These assets may include, among other
things,


                                          7
<PAGE>

   
any gain realized from the charge against the assets of the Account for the
mortality and expense risks assumed by Northwestern Mutual Life. See "Charges
Against the Account Assets", p. 9. To the extent that the amounts deducted for
sales costs exceed the amounts needed, Northwestern Mutual Life will realize a
gain.
    

A deduction equal to 2% of each basic premium is made for state premium taxes.
Premium taxes vary from state to state and currently range from .75% to 3.5% of
life insurance premiums. The 2% rate is an average.  The tax rate for a
particular state may be lower, higher or equal to the 2% deduction.

Northwestern Mutual Life has guaranteed that the death benefit for a Whole Life
Policy will never be less than the face amount of the Policy, regardless of the
investment experience of the Account. For an Extra Ordinary Life Policy,
Northwestern Mutual Life has guaranteed that the death benefit will never be
less than the Minimum Death Benefit stated in the Policy. For both Policies,
there is a deduction of 1-1/2% from each basic premium to compensate
Northwestern Mutual Life for the risk that the insured may die at a point in
time when the death benefit that would ordinarily be paid is less than this
guaranteed minimum amount.

For an Extra Ordinary Life Policy there is a deduction for dividends to be paid
or credited in accordance with the dividend scale in effect on the issue date of
the Policy. This deduction will vary by age of the insured and duration of the
Policy, and is expected to be in the range of approximately 7-17% of the gross
annual premium.

   
The following tables illustrate the amount of net annual premium, for select and
standard risks, to be placed in the Account at the beginning of each Policy year
after the deductions described above:

DEDUCTIONS FOR SINGLE PREMIUM LIFE POLICIES

   
For a Single Premium Life Policy the only deduction from the single 
premium is an administrative charge of $150.00. The administrative costs for 
issuing and maintaining a Single Premium Life Policy are similar to those 
incurred with a Whole Life Policy or an Extra Ordinary Life Policy, except 
for the costs of premium billing and collection. See "Deductions from 
Premiums for Whole Life and Extra Ordinary Life Policies", p. 7. The entire 
premium for a Single Premium Life Policy, after this deduction of $150, is 
placed in the Account when the Policy is issued without any of the other 
deductions which apply to premiums for Whole Life and Extra Ordinary Life 
Policies. There is no annual fee for a Single Premium Life Policy.
    

   
For a Single Premium Life Policy during the first ten Policy years, the 
cash value payable on surrender of the Policy is reduced by a deduction for 
sales costs. The deduction during the first Policy year is not more than 9% 
of the Policy's tabular cash value. See "Cash Value", p. 13. The deduction 
decreases over time until it is eliminated at the end of the tenth Policy 
year. The deduction is intended to recover the costs incurred by Northwestern 
Mutual Life in distributing Single Premium Life Policies which are 
surrendered in their early years. The deduction will never be more than 9% of 
the single premium paid for the Policy, excluding the administrative charge 
of $150.00.
    

The following table illustrates the schedule for the decreasing deduction for
sales costs for a policy surrendered at the end of each of the first ten Policy
years. The illustration is for a Single Premium Life Policy, male age 35. The
schedule varies slightly by age and sex and amount of insurance.

Since the maximum Policy loan limit for a Single Premium Life Policy is based on
the cash value payable on surrender, the amount which may be borrowed during the
first ten years is reduced to reflect the deduction for sales costs which would
be made if the Policy were surrendered on the date of the Policy loan. See
"Policy Loans", p. 14.
    

CHARGES AGAINST THE ACCOUNT ASSETS

   
There is a daily charge to the Account for the mortality and expense risks
assumed by Northwestern Mutual Life. The charge is at the annual rate of .50% of
the assets of the Account. The mortality risk is that insureds may not live as
long as Northwestern Mutual Life estimated. The expense risk is that expenses of
issuing and administering the Policies may exceed the estimated costs.
Northwestern Mutual Life will realize a gain from this charge to the extent it
is not needed to provide benefits and pay expenses under the Policies. The
actual mortality and expense experience under the Policies will be the basis for
determining dividends. See "Annual Dividends", p. 13.
    

The Policies provide that a charge for taxes may be made against the assets of
the Account. Currently, a daily charge for federal income taxes incurred by
Northwestern Mutual Life is being made at the annual rate of .20% of the assets
of the Account. The charge for taxes may be increased, decreased or eliminated
in the future. In no event will the charge for taxes exceed that portion of the
actual tax expenses of Northwestern Mutual Life which is fairly allocable to the
Policies.

GUARANTEE OF PREMIUMS, DEDUCTIONS AND CHARGES

Northwestern Mutual Life guarantees and may not increase the premiums, the
amounts deducted from premiums and the charge for mortality and expense risks.
These amounts will not increase regardless of future changes in longevity or
increases in expenses. The Extra Ordinary Life Policy provides an opportunity to
pay an additional amount of premium after the guaranteed period for the Extra
Life Protection has expired if the Total Death Benefit would otherwise fall
below the initial amount of insurance. See "Extra Ordinary Life Policy", p. 11.

DEATH BENEFIT

   
The death benefit for a variable life insurance policy is, in part, a guaranteed
amount which will not be reduced during the lifetime of the insured so long as
premiums are paid when due and no policy debt is outstanding. The remainder of
the death benefit is the variable insurance amount which fluctuates in response
to actual investment results and is not guaranteed. The amount of any paid-up
additions which have been purchased with dividends is also included in the total
death benefit and, in addition, the Extra Ordinary Life Policy provides some
term insurance during the early Policy years. The relationships among the
guaranteed and variable amounts and any paid-up additions and term insurance
depend on the design of the particular Policy. See "Whole Life Policy and Single
Premium Life Policy", p. 10, and "Extra Ordinary Life Policy", p. 11.
    

VARIABLE INSURANCE AMOUNT. The variable insurance amount reflects, on a
cumulative basis, the investment experience of the Account divisions in which
the Policy has participated. The variable insurance amount is adjusted annually
on each Policy anniversary. For the first Policy year the variable insurance
amount is zero. For any subsequent year it may be either positive or negative.
If the variable insurance amount is positive, subsequent good investment results
will produce a larger variable insurance amount and therefore an increase in the
death benefit. If the variable insurance amount is negative, subsequent good
investment results will first have to offset the negative amount before the
death benefit will increase.

In setting the premium rates for each Policy it has been assumed that investment
results will cause the Account assets supporting the Policy to grow at a net
annual rate of 4%. If the assets grow at a net rate of exactly 4% for a Policy
year, the variable insurance amount will neither increase nor decrease on the
following anniversary. If the net rate of growth exceeds 4%, the variable
insurance amount will increase. If it is less than 4%, the variable insurance
amount will decrease.

The method for calculating the changes in the death benefit is described in the
Policy. The Policy includes a table of net single premiums used to convert the
investment results for a Policy into increases or decreases in the variable
insurance amount. The insurance rates in the table depend on the sex and the
attained age of the insured for each Policy year. For a Whole Life Policy, the
changes in the death benefit will be smaller for a Policy issued with a higher
premium for extra mortality risk. The net single premium for a particular
variable insurance amount is


                                          9
<PAGE>

the price for that amount of paid-up whole life insurance based on the insured's
age at the Policy anniversary.

Because the variable insurance amount is adjusted only on the Policy
anniversary, Northwestern Mutual Life bears the risk that the insured may die
before the next anniversary after an interim period of adverse investment
experience. If investment experience during the interim period is favorable, the
owner of the Policy will forego the benefit and Northwestern Mutual Life will
realize a gain, unless the insured survives to the next Policy anniversary.
However, if at the date of death of the insured the value of the Policy,
considered as a net single premium, would buy more death benefit than the amount
otherwise determined under the Policy, this increased death benefit will be
paid. 

The cost of life insurance increases with the advancing age of the insured, and
therefore a larger dollar amount of investment earnings is required to produce
the same increase in the death benefit in the later Policy years. In general,
however, the effect of investment results on the death benefit will tend to be
greater in the later Policy years because the amount of assets invested for the
Policy will tend to increase as the Policy remains in force.

   
The cost of providing insurance protection under a Policy is reflected in the
cash value of the Policy. See "Cash Value", p. 13. The cost is actuarially
computed for each Policy each year, based on the insured's attained age, the
l980 Commissioners Standard Ordinary Mortality Table and the net insurance
amount at risk under the Policy. The net insurance amount at risk is the total
death benefit for the Policy minus the cash value plus any Policy debt. The cost
of insurance differs each year because the probability of death increases as the
insured advances in age and the net insurance amount at risk decreases or
increases from year to year depending on investment experience. The cost assumes
that all insureds are in the select underwriting risk classification. The
differences in the mortality rates of the various underwriting classifications
are reflected in the different premiums (or different dividend scales) for those
underwriting classifications. The cost of insurance is based on the mortality
table identified above and is guaranteed for the life of a Policy regardless of
any future changes in mortality experience.
    

WHOLE LIFE POLICY AND SINGLE PREMIUM LIFE POLICY.  For a Whole Life Policy or a
Single Premium Life Policy the death benefit is the face amount of the Policy
plus any positive variable insurance amount in force. The death benefit is
adjusted on each Policy anniversary when the variable insurance amount is
determined for the following year. The total death benefit also includes the
amount of insurance provided by any paid-up additions which have been purchased
with dividends and is reduced by the amount of any Policy debt outstanding. The
death benefit for a Whole Life Policy will not be less than the face amount so
long as premiums are paid when due and no Policy debt is outstanding. For a
Single Premium Life Policy the death benefit will not be less than the face
amount so long as no Policy debt is outstanding.

Paid-up additions purchased with dividends are not counted for purposes of the
guarantee that the death benefit of a Whole Life Policy or a Single Premium Life
Policy will never be less than the face amount of the Policy. If the variable
insurance amount is negative, the total death benefit will be the guaranteed
face amount plus the amount of insurance provided by any paid-up additions less
any Policy debt. Paid-up additions are amounts of permanent insurance, paid for
with dividends and added to a basic life insurance policy, for which the premium
for the entire lifetime of the insured has been paid. Paid-up additions have
cash surrender value and loan value.

   
The following example shows how the death benefit for a Whole Life Policy could
vary based on investment results. Using the Policy illustrated on page 43 and
assuming the 12% hypothetical gross investment earnings rate on assets of the
selected Portfolio of the Fund (equivalent to a net rate of 10.85% for the
Account division), and the dividend scale as illustrated, the death benefit
shown at the end of Policy year 5 would change as follows:

EXTRA ORDINARY LIFE POLICY.  The Total Death Benefit for an Extra Ordinary Life
Policy is the sum of the Minimum Death Benefit plus the amount of Extra Life
Protection in force. The Minimum Death Benefit is 60% of the total amount of
insurance for which the Policy is issued, and is guaranteed for the lifetime of
the insured so long as premiums are paid when due and no Policy debt is
outstanding. The amount of Extra Life Protection is initially 40% of the total
amount of insurance. It may increase but it will not decrease during the
guaranteed period, so long as premiums are paid when due, no Policy debt is
outstanding, all dividends are applied to purchase paid-up additions and no
paid-up additions are surrendered for their cash value.

   
Extra Life Protection consists of one year term insurance, positive variable
insurance amount and paid-up additions which have been purchased with dividends.
Term insurance is life insurance which pays a death benefit only if the insured
dies during the term for which the insurance has been purchased. Term insurance
is ordinarily purchased on an annual basis at a cost which rises with the
increasing age of the insured. It has no cash surrender value or loan value. The
variable insurance amount and paid-up additions have been described; see
"Variable Insurance Amount", p. 9 and "Whole Life Policy and Single Premium Life
Policy", p. 10.
    

Initially the entire amount of Extra Life Protection is one year term insurance.
As the Policy remains in force one year term insurance is reduced by any
positive variable insurance amount and paid-up additions, so that the term
insurance is reduced to the amount that will maintain the Total Death Benefit at
the amount for which the Policy was issued. The term insurance is eliminated at
any time when the sum of positive variable insurance amount plus the paid-up
additions equals or exceeds the initial amount of Extra Life Protection.

Northwestern Mutual Life guarantees that the amount of Extra Life Protection
will not be reduced during the guaranteed period, regardless of the Account's
investment experience or the amount of any dividends paid on the Policy, so long
as premiums are paid when due, no Policy debt is outstanding, all dividends are
applied to purchase paid-up additions and no paid-up additions are surrendered
for their cash value. The length of the guaranteed period depends on the age of
the insured when the Policy is issued, and ranges from


                                          11
<PAGE>

37 years at age 15 to 7 years at age 75. At age 35 the guaranteed period is 27
years.

For an insured age 40 or younger, the sum of positive variable insurance amount
plus paid-up additions will exceed the initial amount of Extra Life Protection
at or before the end of the guaranteed period if the assets of the Fund which
support the Policy produce a gross investment rate of return of 8% or better and
dividends are at least equal to those being paid on the current dividend scale.
However, neither the actual investment results nor the dividends to be paid on
the Policy are guaranteed.

After the guaranteed period expires, if the sum of positive variable insurance
amount plus the paid-up additions is less than the initial amount of Extra Life
Protection on any Policy anniversary, Northwestern Mutual Life may reduce the
amount of term insurance for the Policy year. The owner of the Policy will be
given notice of the reduction and an opportunity to pay an additional amount of
premium in order to keep the initial amount of insurance in force. The maximum
premium rate is set forth in the Policy. The owner's right to continue to
purchase term insurance on this basis will terminate as of the first Policy
anniversary when the owner fails to pay the additional premium when due.

   
The following example shows how the components of the Total Death Benefit for an
Extra Ordinary Life Policy could vary based on investment results. Using the
Policy illustrated on page 46 and the assumed 12% hypothetical gross annual
investment earnings rate on assets of the selected Portfolio of the Fund
(equivalent to a net rate of 10.85% for the Account division), and the dividend
scale as illustrated, the amounts shown at the end of Policy year 5 would change
as follows:

Note that the Total Death Benefit is not affected by either investment results
or the amount of dividends paid, because the Policy is within the guaranteed
period of Extra Life Protection. But the components of Extra Life Protection are
affected by both factors. Good investment results and increases in dividends
increase the likelihood that the Total Death Benefit will begin to rise before
the guaranteed period of Extra Life Protection expires. Adverse investment
results or decreases in dividends could cause the Total Death Benefit to fall
below the amount of insurance which was initially in force, after the guaranteed
period of Extra Life Protection expires, but it cannot fall below the Minimum
Death Benefit so long as premiums are paid when due and no Policy debt is
outstanding.

The Extra Ordinary Life Policy is designed for a purchaser who intends to use
all dividends to purchase paid-up additions. If dividends are used for any other
purpose, or if any paid-up additions are surrendered for their cash value, the
term insurance in force will immediately terminate, any remaining guaranteed
period of Extra Life Protection will terminate and the owner's right to purchase
term insurance will terminate. The amount of Extra Life Protection thereafter
will be the sum of positive variable insurance amount plus any paid-up additions
which remain in force.

   
The following example (using the Policy illustrated on page 46, like the
examples above) shows how the Total Death Benefit would be reduced from $100,000
to $63,679, by the elimination of $36,321 of term insurance, if dividends are
used during Policy Year 6 to reduce the premium. The premium of $1,014 would be
reduced by the dividend of $126.34, based on the dividend scale as illustrated,
to a net premium of $887.66. The Total Death Benefit during Policy Year 6 would
then be as follows:

CASH VALUE

   
The cash value for the Whole Life Policy, the Extra Ordinary Life Policy and the
Single Premium Life Policy will change daily in response to investment results.
No minimum cash value is guaranteed. Calculation of the cash value for any date
requires three steps. First, the amount shown for the preceding anniversary in
the table of cash values at the front of the Policy is noted and adjusted for
the time elapsed since the last Policy anniversary. The tabular cash values are
based on the assumed net investment rate of 4%, the 1980 Commissioners Standard
Ordinary Mortality Table and the deductions from the premiums. See "Deductions
from Premiums for Whole Life and Extra Ordinary Life Policies", p. 7. For the
Single Premium Life Policy the calculation begins with the adjusted tabular cash
value, which reflects the deduction for sales costs if the Policy is surrendered
during the first ten years. See "Deductions for Single Premium Life Policies",
p. 8. Second, the net single premium for the variable insurance amount is added
to the tabular cash value. See the discussion of net single premiums under
"Variable Insurance Amount", p. 9. If the variable insurance amount is negative,
the net single premium is a negative amount. A table of net single premiums for
the insured at each Policy anniversary is in the Policy. Third, the algebraic
sum of the tabular cash value and the net single premium for the variable
insurance amount is adjusted to reflect investment results from the last Policy
anniversary to the date for which the calculation is being made. The cash value
is increased by the value of any paid-up additions which have been purchased
with dividends.
    

If a portion of the premium for the current Policy year has not been paid, the
cash value of a Whole Life Policy or an Extra Ordinary Life Policy will be
reduced. There is not likely to be any cash value for a Whole Life Policy or an
Extra Ordinary Life Policy during the early part of the first year because of
the first year deductions.

The cash value for the Whole Life Policy, the Extra Ordinary Life Policy and the
Single Premium Life Policy will be reduced by the amount of any Policy debt
outstanding.

The cash value for a Policy is determined at the end of each valuation period.
Each business day, together with any non-business days before it, is a valuation
period. A business day is any day on which the New York Stock Exchange is open
for trading. In accordance with the requirements of the Investment Company Act
of l940, the cash value for a Policy may also be determined on any other day on
which there is sufficient trading in securities to materially affect the value
of the securities held by the Portfolios of the Fund.

   
The owner of a Policy may surrender it for the cash value at any time during the
lifetime of the insured. Alternatively, the cash value of a Whole Life Policy or
an Extra Ordinary Life Policy may be applied to provide extended term insurance
or a reduced amount of fixed or variable paid-up insurance. See "Extended Term
and Paid-Up Insurance", p. 15.
    

The Policies do not include any provision for a partial surrender. By
administrative practice Northwestern Mutual Life will permit the owner of a
Policy to split it into two Policies and surrender one of them, so long as the
new Policy meets the regular minimum size requirements. The Policy which
continues in force will be based on the age and risk classification of the
insured at the time of issuance of the original Policy.

ANNUAL DIVIDENDS

The Policies share in divisible surplus to the extent determined annually by
Northwestern Mutual Life. A Policy's share will be distributed annually as a
dividend payable on each Policy anniversary beginning at the end of the second
year. For Single Premium Life Policies, and some other Policies, the first
distribution will be at the end of the first year. No dividend will be paid on a
Whole Life Policy or an Extra Ordinary Life Policy in force as extended term
insurance.

Dividends under participating policies may be described as refunds of premiums
which adjust the cost of a policy to the actual level of cost emerging over time
after the policy's issue. Thus participating policies generally have gross
premiums which are higher than those for comparable non-participating policies.
Both federal and state tax law recognize that a dividend is considered to be a
refund of a portion of the premium paid.

Dividend illustrations published at the time a life insurance policy is issued
reflect the actual recent experience of the issuing company with respect to
investment earnings, mortality and expenses. State law generally prohibits a
company from projecting or estimating future results. State law also requires
that dividends be paid out of surplus, after certain necessary amounts are set
aside, and that such surplus be apportioned equitably among participating
policies. In summary, dividends must be based on actual experience and cannot be
guaranteed at issue of a policy.


                                          13
<PAGE>

Northwestern Mutual Life's actuary annually examines current and recent
experience and compares these actual results with those which were assumed in
determining premium rates when each class of policies was issued. Classes are
determined by such factors as year of issue, age, plan of insurance and risk
classification. The actuary then determines the amount of dividends to be
equitably apportioned to each class of policies. Following the actuary's
recommendations, the Trustees of Northwestern Mutual Life adopt a dividend scale
each year, thereby authorizing the distribution of the dividend.

Northwestern Mutual Life has no significant actual mortality experience with
variable life insurance policies. For purposes of the current dividend scale
used for the illustrations in this prospectus, it has been assumed that
mortality experience in connection with the Policies will be comparable to that
actually experienced with fixed benefit life insurance.

   
The prospectus illustrations show dividends being used to purchase variable
paid-up additions. Dividends may also be paid in cash, used to pay premiums or
left to accumulate with interest; but unless all dividends paid on an Extra
Ordinary Life Policy are used to purchase paid-up additions, the term insurance
portion of the Extra Life Protection will be terminated. See "Extra Ordinary
Life Policy", p. 11. Dividends left to accumulate with interest will be held in
the general account of Northwestern Mutual Life and will be credited with a rate
of interest determined annually but not less than an annual effective rate of
3-l/2%. If a Whole Life Policy or an Extra Ordinary Life Policy is in force as
reduced fixed benefit paid-up insurance, dividends may be used to purchase fixed
benefit paid-up additions. See "Extended Term and Paid-Up Insurance", p. 15.
    

POLICY LOANS

The owner of a Policy may borrow up to 90% of the Policy's cash value using the
Policy as security. The limit is 75% of the cash value during the first two
Policy years. If a Policy loan is already outstanding, the maximum amount for
any new loan is determined by applying these percentage limitations to the
amount of cash value which the Policy would have if there were no loan. Loan
proceeds may be taken in cash or, for the Whole Life and Extra Ordinary Life
Policies, may be applied to pay premiums on the Policy.

Interest on a Policy loan accrues and is payable on a daily basis. Unpaid
interest is added to the amount of the loan. If the amount of the loan equals or
exceeds the Policy's cash value, the Policy will terminate. The owner will be
given a notice at least 31 days before the termination date. The notice will
show how much must be repaid to keep the Policy in force.

The Policy loan interest rate is selected by the owner. A specified annual
effective rate of 8% is one choice. The other choice is a variable rate based on
a corporate bond yield index. The variable rate will be adjusted annually and
will not be less than 5%.

The amount of a Policy loan, including interest as it accrues, will be taken
from the Account divisions in proportion to the amounts in the divisions. The
amounts withdrawn will be transferred to Northwestern Mutual Life's general
account and will be credited on a daily basis with an annual earnings rate equal
to the Policy loan interest rate less a charge for the mortality and expense
risks assumed by Northwestern Mutual Life and for expenses, including taxes. The
aggregate charge is currently at the annual rate of .85% for the 8% specified
Policy loan interest rate and .85% for the variable Policy loan interest rate.
For example, the earnings rate corresponding to the specified 8% Policy loan
interest rate is currently 7.15%. A Policy loan, even if it is repaid, will have
a permanent effect on the Policy's variable insurance amount and cash value
because the amounts borrowed will not participate in the Account's investment
results while the loan is outstanding. The effect may be either favorable or
unfavorable depending on whether the earnings rate credited to the loan amount
is higher or lower than the rate credited to the unborrowed amount left in the
Account.

   
For example, using the Policy illustrated on page 45 and the 6% hypothetical
gross rate for the Account (equivalent to a net rate of 4.85%), and assuming a
Policy loan of $3,181 (90% of the cash value) at the end of Policy year 5, with
the 8% Policy loan interest rate (corresponding to a net earnings rate of
7.15%), the loan will affect the variable insurance amount and cash value
(before subtracting the loan amount and interest) at the end of the next three
Policy years as follows:

</TABLE>
    

   
The difference results from the fact that the earnings rate for the amount of
the loan is 7.15% rather than the net rate of 4.85% for the Account.
    

A Policy loan, and any accrued interest outstanding, may be repaid, in whole or
in part, at any time. Payments will be credited as of the date received and will
be transferred from the general account of Northwestern Mutual Life to the
Account divisions, in


                                          14
<PAGE>

proportion to the amounts in the divisions, as of the same date.

EXTENDED TERM AND PAID-UP INSURANCE

   
If a premium for a Whole Life Policy or an Extra Ordinary Life Policy is not
paid within the 31-day grace period (see "Grace Period", p. 6), the owner may
use the cash value to provide a reduced amount of either fixed or variable
benefit paid-up insurance. If neither of these options is chosen, and the Policy
is not surrendered, the insurance will remain in force as extended term
insurance.
    

If the cash value is used to provide a reduced amount of fixed benefit paid-up
insurance or for extended term insurance the amount of the cash value will be
transferred from the Account to Northwestern Mutual Life's general account.
Thereafter the Policy will not participate in the Account's investment results
unless the Policy is subsequently reinstated. See "Reinstatement", below.
Variable benefit paid-up insurance may be selected only if the Policy meets a
$1,000 cash value minimum test.

The selection of paid-up insurance must be made within three months after the
due date of the first unpaid premium. The amount of paid-up insurance is
determined by the amount of cash value and the age and sex of the insured, using
the table of net single premiums at the attained age. Fixed benefit paid-up
insurance has guaranteed cash and loan values. Paid-up insurance remains in
force for the lifetime of the insured unless the Policy is surrendered. 

If the Policy remains in force as extended term insurance the amount of
insurance will equal the Total Death Benefit prior to the date the premium was
due. The amount of cash value and the age and sex of the insured will determine
how long the insurance continues. Northwestern Mutual Life will, upon request,
tell the owner of a Policy the amount of insurance and how long the term will
be. Extended term insurance is not available if the Policy was issued with a
higher premium for extra mortality risk. Extended term insurance has a cash
value but no loan value.

   
Using the Policy illustrated on pages 44 and 46 and assuming the 0% and 12%
hypothetical gross rates for the Account, the cash value of $3,025 or $4,117 at
the end of Policy year 5 would provide the following amounts of reduced paid-up
insurance or $100,000 of extended term insurance for the following periods:

REINSTATEMENT

If a premium for a Whole Life Policy or an Extra Ordinary Life Policy is due and
remains unpaid after the grace period expires, the Policy may be reinstated
within five years after the premium due date. The insured must provide
satisfactory evidence of insurability. A substantial payment may be required.
The Policy may not be reinstated if it has been surrendered for its cash value.

RIGHT TO RETURN POLICY

A Policy may be returned for a full refund of the premium paid within 45 days
after the application for insurance is signed, or within 10 days after the
Policy is received, or within 10 days after a Notice of Cancellation Right is
mailed or delivered to the owner, whichever date is latest. The Policy may be
mailed or delivered to the agent who sold it or to the Home Office of
Northwestern Mutual Life. If returned, the Policy will be considered void from
the beginning.

RIGHT TO EXCHANGE FOR A FIXED BENEFIT POLICY

The owner may exchange a Policy for a conventional whole life insurance policy
with benefits that do not vary with the investment experience of a separate
account. The exchange may be elected at any time within twenty-four months after
the issue date of the Policy provided premiums are duly paid. Evidence of
insurability is not required.

The new policy will be on the life of the same insured and will have the same
face amount, policy date and issue age. The premiums and cash values will be the
same as those for policies issued by Northwestern Mutual Life on the issue date
of the Policy.

The exchange will be subject to an equitable cash adjustment. The amount will
recognize the difference in premiums and investment performance of the two
policies.

An exchange will be effective when Northwestern Mutual Life receives a proper
written request, as well as the Policy and any amount due on the exchange.

The owner of a Policy may also exchange it for a fixed benefit policy if the
Fund changes its investment adviser or if there is a material change in the
investment policies of a Fund portfolio. The owner will be given notice of any
such change and will have 60 days to make the exchange.

OTHER POLICY PROVISIONS

OWNER. The owner is identified in the Policy. The owner may exercise all rights
under the Policy while the insured is living. Ownership may be transferred to


                                          15

another. Written proof of the transfer must be received by Northwestern Mutual
Life at its Home Office.

BENEFICIARY. The beneficiary is the person to whom the death benefit is payable.
The beneficiary is named in the application. After the Policy is issued the
owner may change the beneficiary in accordance with the Policy provisions.

INCONTESTABILITY. Northwestern Mutual Life will not contest a Policy after it
has been in force during the lifetime of the insured for two years from the date
of issue.

SUICIDE. If the insured dies by suicide within one year from the date of issue,
the amount payable under the Policy will be limited to the premiums paid.

MISSTATEMENT OF AGE OR SEX. If the age or sex of the insured has been misstated,
benefits under a Policy will be adjusted to reflect the correct age and sex.

COLLATERAL ASSIGNMENT. The owner may assign a Policy as collateral security.
Northwestern Mutual Life is not responsible for the validity or effect of a
collateral assignment and will not be deemed to know of an assignment before
receipt of the assignment in writing at the Home Office.

PAYMENT PLANS. The Policy provides a variety of payment plans for Policy
benefits. Any Northwestern Mutual Life agent authorized to sell the Policies can
explain these provisions on request.

DEFERRAL OF DETERMINATION AND PAYMENT. So long as premiums have been paid when
due, Northwestern Mutual Life will ordinarily pay Policy benefits within seven
days after receipt of all required documents at its Home Office. However,
determination and payment of benefits may be deferred during any period when it
is not reasonably practicable to value securities because the New York Stock
Exchange is closed or an emergency exists or the Securities and Exchange
Commission, by order, permits deferral for the protection of policyowners.

If a Whole Life Policy or an Extra Ordinary Life Policy is continued in force as
extended term or reduced paid-up insurance, Northwestern Mutual Life has the
right to defer payment of the cash value for up to six months from the date of a
Policy loan or surrender. If payment is deferred for 30 days or more interest
will be paid at an annual effective rate of 4%.

VOTING RIGHTS

Northwestern Mutual Life is the owner of the Fund shares in which all assets of
the Account are invested. As the owner of the shares Northwestern Mutual Life
will exercise its right to vote the shares to elect directors of the Fund, to
vote on matters required to be approved or ratified by mutual fund shareholders
under the Investment Company Act of 1940 and to vote on any other matters that
may be presented to any Fund shareholders' meeting. However, Northwestern Mutual
Life will vote the Fund shares held in the Account in accordance with
instructions from owners of the Policies. Northwestern Mutual Life will vote the
Fund shares held in its general account in the same proportions as the shares
for which voting instructions are received. If the applicable laws or
regulations change so as to permit Northwestern Mutual Life to vote the Fund
shares in its own discretion, it may elect to do so.

The number of Fund shares for each division of the Account for which the owner
of a Policy may give instructions is determined by dividing the amount of the
Policy's cash value apportioned to that division, if any, by the per share value
for the corresponding Fund Portfolio. The number will be determined as of a date
chosen by Northwestern Mutual Life, but not more than 90 days before the Fund
shareholders' meeting. Fractional votes are counted. Voting instructions will be
solicited with written materials at least 14 days before the meeting. Shares as
to which no instructions have been received will be voted in the same proportion
as the shares as to which instructions have been received.

Northwestern Mutual Life may, if required by state insurance officials,
disregard voting instructions which would require Fund shares to be voted for a
change in the sub-classification or investment objectives of a Fund Portfolio,
or to approve or disapprove an investment advisory agreement for the Fund.
Northwestern Mutual Life may also disregard voting instructions that would
require changes in the investment policy or investment adviser for the Fund or a
Fund Portfolio, provided that Northwestern Mutual Life reasonably determines to
take this action in accordance with applicable federal law. If Northwestern
Mutual Life disregards voting instructions a summary of the action and reasons
therefor will be included in the next semiannual report to the owners of the
Policies.

SUBSTITUTION OF FUND SHARES AND OTHER CHANGES

If, in the judgment of Northwestern Mutual Life, a Fund Portfolio becomes
unsuitable for continued use with the Policies because of a change in investment
objectives or restrictions, shares of another Portfolio or another mutual fund
may be substituted. Any substitution of shares will be subject to any required
approval of the Securities and Exchange Commission, the Wisconsin Commissioner
of Insurance or other regulatory authority. Northwestern Mutual Life has also
reserved the right, subject to applicable federal and state law, to operate the
Account or any of its divisions as a management company under the Investment
Company Act of 1940, or in any other


                                          16

form permitted, or to terminate registration of the Account if registration is
no longer required, and to change the provisions of the Policies to comply with
any applicable laws.

REPORTS

For each Policy year (unless a Whole Life Policy or an Extra Ordinary Life
Policy is in force as extended term or fixed benefit paid-up insurance) the
owner of a Policy will receive a statement showing the death benefit, cash value
and any Policy loan (including interest charged) as of the anniversary date.
Owners will also receive annual and semiannual reports for the Account and the
Fund, including financial statements.

SPECIAL POLICY FOR EMPLOYERS

The premium for the standard Policy is based in part on the sex of the insured.
The standard annuity rates for payment plans which last for the lifetime of the
payee are also based, in part, on the sex of the payee. For certain situations
where the insurance involves an employer sponsored benefit plan or arrangement,
federal law and the laws of certain states may require that premiums and annuity
rates be determined without regard to sex. Special Whole Life Policies, Extra
Ordinary Life Policies and Single Premium Life Policies are available for this
purpose. Prospective purchasers of the Policies are urged to review any
questions in this area with qualified counsel.

DISTRIBUTION OF THE POLICIES

The Policies will be sold through individuals who, in addition to being licensed
life insurance agents of Northwestern Mutual Life, are registered
representatives of Northwestern Mutual Investment Services, Inc. ("NMIS"), a
wholly-owned subsidiary of Northwestern Mutual Life. NMIS is a registered
broker-dealer under the Securities Exchange Act of 1934 and is a member of the
National Association of Securities Dealers.

Commissions paid to the agents on sales of the Whole Life and Extra Ordinary
Life Policies will not exceed 55% of the premium for the first year, 9% of the
premium for the second and third years, 6% of the premium for the fourth through
seventh years and 3% of the premium for the eighth through tenth years.
Thereafter a persistency fee of 2% of premiums may be paid to the agent. For the
Single Premium Life Policies commissions are 2-3/4% of the premium.

Agents who meet certain productivity and persistency standards receive
additional compensation. New agents may be paid differently during a training
period. General agents and district agents who are registered representatives of
NMIS and have supervisory responsibility for sales of the Policies receive
commission overrides and other compensation.

TAX TREATMENT OF POLICY BENEFITS

The Policies are "life insurance contracts" as that term is defined in sections
7702 and 817(h) of the Internal Revenue Code. Increases in cash value under a
Policy are not taxable until actual surrender of the Policy. Upon surrender, the
amount received is taxable at ordinary income rates under section 72(e) of the
Code to the extent it exceeds the amount of the premiums paid under the Policy
less any dividends or other amounts previously received tax-free (basis of the
Policy). Death benefits are excludable from the beneficiary's gross income under
section l0l(a) of the Code.

Northwestern Mutual Life believes that loans received under the Policies (except
certain Single Premium Life Policies) will be construed as indebtedness of an
owner in the same manner as loans under a fixed benefit life insurance policy
and that no part of any loan under a Policy will constitute income to the owner.

For Single Premium Life Policies issued after June 20, 1988, partial
withdrawals, Policy loans and dividends paid in cash are taxable as income to
the extent the cash value of the Policy exceeds the basis of the Policy. The
taxable portion of these distributions would also be subject to a 10% penalty if
received prior to age 59 1/2, disability or annuitization. For purposes of
determining taxable income, all Single Premium Life Policies (including any
fixed dollar single premium policies or other modified endowment contracts under
Section 7702A) issued by Northwestern Mutual Life to the Policy owner during the
same calendar year are aggregated.

Federal estate and state and local estate, inheritance and other tax
consequences of ownership or receipt of Policy proceeds depend upon the
circumstances of each Policy owner or beneficiary.

The foregoing summary does not purport to be complete or to cover all
situations. Counsel and other competent advisers should be consulted for more
complete information.

REPORT OF INDEPENDENT ACCOUNTANTS
 
To The Northwestern Mutual Life Insurance Company and
Policyowners of Northwestern Mutual Variable Life Account
 
In our opinion, the accompanying combined statement of assets and liabilities
and the related combined and separate statements of operations and changes in
equity present fairly, in all material respects, the financial position of
Northwestern Mutual Variable Life Account and Aggressive Growth Stock Division,
International Equity Division, Growth Stock Division, Growth and Income Stock
Division, the Index 500 Stock Division, the Balanced Division, High Yield Bond
Division, Select Bond Division, and Money Market Division thereof at December
31, 1997, the results of their operations and the changes in their equity for
the year then ended and for each of the other periods presented, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of The Northwestern Mutual Life Insurance Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
direct confirmation of the number of shares owned at December 31, 1997 with
Northwestern Mutual Series Fund, Inc., provide a reasonable basis for the
opinion expressed above.

DECEMBER 31, 1997
 
NOTE 1 -- Northwestern Mutual Variable Life Account (the "Account") is
registered as a unit investment trust under the Investment Company Act of 1940
and is a segregated asset account of The Northwestern Mutual Life Insurance
Company ("Northwestern Mutual Life") used to fund variable life insurance
policies.
 
NOTE 2 -- The preparation of the financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Principal
accounting policies are summarized below.
 
NOTE 3 -- All assets of each Division of the Account are invested in shares of
the corresponding Portfolio of Northwestern Mutual Series Fund, Inc. (the
"Fund"). The shares are valued at the Fund's offering and redemption price per
share. The Fund is a diversified open-end investment company registered under
the Investment Company Act of 1940.
 
NOTE 4 -- Dividend income from the Fund is recorded on the record date of the
dividends. Transactions in Fund shares are accounted for on the trade date. The
basis for determining cost on sale of Fund shares is identified cost. Purchases
and sales of Fund shares for the year ended December 31, 1997 by each Division

NOTE 5 -- A deduction for mortality and expense risks is determined daily and
paid to Northwestern Mutual Life. Generally, for policies issued before October
11, 1995, and policies issued on or after October 11, 1995 the deduction is at
an annual rate of .50% and .60%, respectively, of the net assets of the Account.
The mortality risk is that insureds may not live as long as estimated. The
expense risk is that expenses of issuing and administering the policies may
exceed the estimated costs.
 
Certain deductions are also made from the annual or single premiums before
accounts are allocated to the Account. These deductions are for (1) sales load,
(2) administrative expenses, (3) taxes and (4) a risk charge for the guaranteed
minimum death benefit.
 
Additional mortality costs are deducted from the policy annually and are paid to
Northwestern Mutual Life to cover the cost of providing insurance protection.
This cost is actuarially calculated based upon the insured's age, the 1980
Commissioners Standard Ordinary Mortality Table and the amount of insurance
provided under the policy.
 
NOTE 6 -- Northwestern Mutual Life is taxed as a "life insurance company" under
the Internal Revenue Code. The variable life insurance policies which are funded
in the Account are taxed as part of the operations of Northwestern Mutual Life.
Policies provide that a charge for taxes may be made against the assets of the
Account. Generally, for policies issued before October 11, 1995, Northwestern
Mutual Life charges the Account at an annual rate of .20% of the Account's net
assets and reserves the right to increase, decrease or eliminate the charge for
taxes in the future. Generally, for policies issued on or after October 11,
1995, there is no charge being made against the assets of the Account for
federal income taxes, but Northwestern Mutual Life reserves the right to charge
for taxes in the future.
 
NOTE 7 -- The Account is credited for the policyowners' net annual premiums at
the respective policy anniversary dates regardless of when policyowners actually
paid their premiums. Northwestern Mutual Life's equity represents any unpaid
portion of net annual premiums.

THE NORTHWESTERN MUTUAL LIFE INSURANCE COMPANY
 
NOTES TO CONSOLIDATED STATUTORY FINANCIAL STATEMENTS
 
DECEMBER 31, 1997, 1996 AND 1995
 
NOTE 1 -- PRINCIPAL ACCOUNTING POLICIES
 
The accompanying consolidated statutory financial statements include the
accounts of The Northwestern Mutual Life Insurance Company ("Company") and its
wholly-owned life insurance subsidiary, Northwestern Long Term Care Insurance
Company ("Subsidiary"). The Company offers life, annuity and disability income
products to the personal, business, estate and tax-qualified markets.
 
The consolidated financial statements have been prepared using accounting
policies prescribed or permitted by the Office of the Commissioner of Insurance
of the State of Wisconsin ("statutory basis of accounting"). Prior to December
15, 1995, these policies were considered generally accepted accounting
principles ("GAAP") for mutual life insurance enterprises. However, in April
1993, the Financial Accounting Standards Board issued Interpretation No. 40,
"Applicability of Generally Accepted Accounting Principles to Mutual Life
Insurance Companies and Other Enterprises," which established a different
definition of GAAP for mutual life insurance enterprises. Under the
Interpretation, financial statements of mutual life insurance enterprises for
periods beginning after December 15, 1995 which are prepared on the statutory
basis of accounting are no longer characterized as being in conformity with
GAAP.
 
Financial statements prepared on the statutory basis of accounting vary from
financial statements prepared on a GAAP basis primarily because on a GAAP basis
(1) policy acquisition costs are deferred and amortized, (2) investment
valuations and insurance reserves are based on different assumptions, (3) funds
received under deposit-type contracts are not reported as premium revenue, and
(4) deferred taxes are provided for temporary differences between book and tax
basis of certain assets and liabilities. The effects on the financial statements
of the differences between the statutory basis of accounting and GAAP are
material to the Company.
 
The preparation of financial statements in conformity with the statutory basis
of accounting requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual future results could differ from these estimates.
 
INVESTMENTS
 
The Company's investments are valued on the following bases:
 
<TABLE>
<S>                             <C>  <C>
Bonds                           --   Amortized cost using the interest method; loan-backed and
                                      structured securities are amortized using estimated
                                      prepayment rates and, generally, the prospective adjustment
                                      method
Common and preferred stocks     --   Common stocks are carried at market value, preferred stocks
                                      are generally carried at cost, and unconsolidated
                                      subsidiaries are recorded as equity in subsidiaries' net
                                      assets
Mortgage loans                  --   Amortized cost
Real estate                     --   Lower of cost, less depreciation and encumbrances, or
                                      estimated net realizable value
Policy loans                    --   Unpaid principal balance, which approximates fair value
Other investments               --   Consists primarily of joint ventures which are valued at
                                      equity in ventures' net assets
Cash and temporary investments  --   Amortized cost, which approximates fair value

investment income is reduced by investment management expenses, real estate
depreciation and depletion related to energy assets.
 
INTEREST MAINTENANCE RESERVE
 
The Company is required to maintain an interest maintenance reserve ("IMR"). The
IMR is used to defer realized gains and losses, net of tax, on fixed income
investments resulting from changes in interest rates. Net realized gains and
losses deferred to the IMR are amortized into investment income over the
approximate remaining term to maturity of the investment sold.
 
ASSET VALUATION RESERVE
 
The Company is required to maintain an asset valuation reserve ("AVR"). The AVR
establishes a general reserve for invested assets held by the Company using a
formula prescribed by state regulations. The AVR is designed to stabilize the
general contingency reserves against potential declines in the value of
investments.
 
SEPARATE ACCOUNT BUSINESS
 
Separate account assets and related policy liabilities represent the segregation
of funds deposited by "variable" life insurance and annuity policyowners.
Policyowners bear the investment performance risk associated with variable
products. Separate account assets are invested at the direction of the
policyowner in a variety of Company-managed mutual funds and/or a fixed interest
rate option. Separate account assets are reported at fair market value.
 
RESERVES FOR POLICY BENEFITS
 
Reserves for policy benefits are determined by actuarial estimates based on
mortality and morbidity experience tables and valuation interest rates
prescribed by the Office of the Commissioner of Insurance of the State of
Wisconsin. See Note 3.
 
PREMIUM REVENUE AND OPERATING EXPENSES
 
Life insurance premiums are recognized as revenue at the beginning of each
policy year. Annuity and disability income premiums are recognized when received
by the Company. Operating expenses, including costs of acquiring new policies,
are charged to operations as incurred.

STOCKS
 
The estimated market values of common and perpetual preferred stocks are based
upon quoted market prices, if available. For securities not actively traded,
fair values are estimated using independent pricing services or internally
developed pricing models.
 
The cost of common and preferred stock held by the Company at December 31, 1997
and 1996 is $5.0 billion and $3.7 billion, respectively.
 
MORTGAGE LOANS AND REAL ESTATE
 
Mortgage loans are collateralized by properties located throughout the United
States and Canada. The Company attempts to minimize mortgage loan investment
risk by diversification of geographic locations and types of properties.
 
The fair value of mortgage loans as of December 31, 1997 and 1996 was 
approximately $11.5 billion and $9.8 billion, respectively. The fair value of 
the mortgage loan portfolio is estimated by discounting the future estimated 
cash flows using current interest rates of debt securities with similar 
credit risk and maturities, or utilizing net realizable values.
 
At December 31, 1997, real estate includes $61 million acquired through
foreclosure and $124 million of home office real estate. In 1997 and 1996, the
Company recorded unrealized losses of $2 million and $43 million, respectively,
for the excess of carrying value over fair value of certain real estate
investments and mortgage loans.

SECURITIES LENDING
 
The Company has entered into a securities lending agreement whereby certain
securities are loaned to third parties, primarily major brokerage firms. The
Company's policy requires a minimum of 102 percent of the fair value of the
loaned securities as collateral, calculated on a daily basis in the form of
either cash or securities. Collateral assets received and related liability due
to counterparties of $1.5 billion and $1.0 billion are included in the
consolidated statements of financial position at December 31, 1997 and 1996,
respectively, and approximate the statement value of securities loaned at those
dates.
 
INVESTMENT IN MGIC
 
The Company owns 18.4% (20.9 million shares) of the outstanding common stock of
MGIC Investment Corporation ("MGIC"). This investment is accounted for using the
equity method. At December 31, 1997, the market value of the Company's
investment in MGIC exceeded the statement value of $273 million by $768 million.
 
In July 1995, the Company entered into a forward contract with a brokerage firm
to deliver 8.8 million to 10.7 million shares of MGIC (or cash in an amount
equal to the market value of the MGIC shares at contract maturity) in August,
1998, in exchange for a fixed cash payment of $247 million ($24 per share). The
Company's objective in entering into the forward contract was to hedge against
depreciation in the value of its MGIC holdings during the contract period below
the initial spot price of $24, while partially participating in appreciation, if
any, during the forward contract's duration.

DERIVATIVE FINANCIAL INSTRUMENTS
 
In the normal course of business, the Company enters into transactions to reduce
its exposure to fluctuations in interest rates, foreign currency exchange rates
and market volatility. These hedging strategies include the use of forwards,
futures, options and swaps. In addition to the use of derivatives for hedging
purposes, equity swaps were held for investment purposes during 1997.
 
The Company held the following positions for hedging purposes at December 31,
1997:

</TABLE>
 
The notional or contractual amounts of derivative financial instruments are used
to denominate these types of transactions and do not represent the amounts
exchanged between the parties.
 
The notional amount of equity swaps outstanding at December 31, 1997 was $143
million.
 
The hedges are recorded by the Company in the same manner as the underlying
investments. Foreign currency forwards, foreign currency swaps, stock futures,
and options to acquire interest rate swaps are reported at market value. There
is no statement value reported for interest rate swaps and bond futures prior to
the settlement of the contract. Changes in the values of these contracts are
expected to offset gains and losses on the hedged items. For hedges reported at
market value, gains and losses are unrealized until expiration of the contract.
The effect of derivative transactions is not material to the Company's results
of operations or financial position.
 
NOTE 3 -- RESERVES FOR POLICY BENEFITS
 
Life insurance reserves on substantially all policies issued since 1978 are
based on the Commissioner's Reserve Valuation Method ("CRVM") with interest
rates ranging from 3 1/2% to 5 1/2%. Other life policy reserves are based
primarily on the net level premium method employing various mortality tables at
interest rates ranging from 2% to 4 1/2%.
 
Deferred annuity reserves on contracts issued since 1985 are valued using CRVM
with interest rates ranging from 3 1/2% to 6 1/4%. Other deferred annuity
reserves are based on the contract value. Immediate annuity reserves are based
on present values of expected benefit payments at interest rates ranging from
3 1/2% to 7 1/2%.

                        DECEMBER 31, 1997, 1996 AND 1995
 
Active life reserves for disability income ("DI") policies issued since 1987 are
primarily based on the two-year preliminary term method using a 4% interest rate
and the 1985 Commissioner's Individual Disability Table A ("CIDA") for
morbidity. Active life reserves for prior DI policies are estimated using the
net level premium method, a 3% to 4% interest rate and the 1964 Commissioner's
Disability Table for morbidity. Disabled life reserves for DI policies are based
on the present values of expected benefit payments using primarily the 1985 CIDA
(modified for Company experience in the first two years of disability) with
interest rates ranging from 3% to 5 1/2%.
 
Use of these actuarial tables and methods involves estimation of future
mortality and morbidity based on past experience. Actual future experience could
differ from these estimates.
 
NOTE 4 -- EMPLOYEE AND AGENT BENEFIT PLANS

   
The Company sponsors noncontributory defined benefit retirement plans for all
eligible employees and agents. The expense associated with these plans is
generally recorded by the Company in the period contributions to the plans are
funded. As of January 1, 1997, the most recent actuarial valuation date
available, the defined benefit plans were fully funded. In addition, the Company
has a contributory 401(k) plan for eligible employees and a noncontributory
defined contribution plan for all full-time agents. The Company's contributions
are expensed in the period contributions are required under the plan. The 
defined benefit and defined contribution plans' assets of $1.4 billion at 
December 31, 1997 are primarily invested in the separate accounts of the 
Company.
    

In addition to pension benefits, the Company provides certain health care and
life insurance benefits ("postretirement benefits") for retired employees.
Substantially all employees may become eligible for these benefits if they reach
retirement age while working for the Company. Postretirement benefit cost for
the year ended December 31, 1997 was a net benefit of $1.3 million; it includes
the expected cost of postretirement benefits for newly eligible and vested
employees, interest cost and return on plan assets totaling $3.6 million, offset
by gains from favorable differences between actuarial assumptions and actual
experience of $4.9 million.

If the health care cost trend rate assumptions were increased by 1%, the accrued
postretirement benefit obligation as of December 31, 1997 would be increased by

At December 31, 1997, the recorded postretirement benefit obligation was reduced
by $20 million for assets funded for postretirement health care benefits.

NOTE 5 -- REINSURANCE

   
In the normal course of business, the Company seeks to limit its exposure to
loss on any single insured and to recover a portion of benefits paid by ceding
to reinsurers under excess coverage and co-insurance contracts. The Company
retains a maximum of $15 million of coverage per individual life and $20 million
maximum of coverage per joint life. The Company has an excess reinsurance
contract for disability income policies with retention limits varying based upon
coverage type.
    

The amounts shown in the accompanying consolidated financial statements are net
of reinsurance activity. Benefit reserves at December 31, 1997 and 1996 are
reported net of reinsurance of $435 million and $355 million, respectively. The
effect of reinsurance on premiums and benefits for the years ended December 31,
1997, 1996 and 1995 is as follows:

In addition, the Company received $115 million, $93 million and $67 million in
1997, 1996 and 1995 respectively, from reinsurers representing reimbursement of
commissions and other expenses. These amounts are included in other income in
the consolidated statement of operations.
 
Reinsurance contracts do not relieve the Company from its obligations to
policyholders. Failure of reinsurers to honor their obligations could result in
losses to the Company; consequently, allowances are established for amounts
deemed uncollectible. The Company evaluates the financial condition of its
reinsurers and monitors concentrations of credit risk arising from similar
geographic regions, activities, or economic characteristics of the reinsurers to
minimize its exposure to significant losses from reinsurer insolvencies
 
NOTE 6 -- INCOME TAXES
 
Provisions for income taxes are based on current income tax payable without
recognition of deferred taxes. The Company files a consolidated life-nonlife
federal income tax return. Federal income tax returns for years through 1988 are
closed as to further assessment of tax. Adequate provision has been made in the
financial statements for any additional taxes which may become due with respect
to the open years.
 
The Company's effective tax rate on gains from operations before income tax
expense (after dividends) in 1997, 1996 and 1995 were 56%, 67% and 60%,
respectively. The Company's effective tax rate exceeds the federal corporate
rate of 35% because, (1) the Company pays a tax that is assessed only on mutual
life insurance companies which treats a portion of policyholder dividends like
nondeductible dividends paid to shareholders of stock companies ("equity tax"),
and (2) the Company must capitalize and amortize (as opposed to immediately
deducting) an amount deemed to represent the cost of acquiring new business
("DAC tax").

NOTE 7 -- CONTINGENCIES
 
The Company has guaranteed certain obligations of its affiliates. These
guarantees totaled approximately $112 million at December 31, 1997 and are
generally supported by the underlying net asset values of the affiliates.
 
The Company is engaged in various legal actions in the normal course of its
investment and insurance operations. In the opinion of management, any losses
resulting from such actions would not have a material effect on the Company's
financial condition.

REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Trustees and Policyowners of
The Northwestern Mutual Life Insurance Company
 
We have audited the accompanying consolidated statement of financial position of
The Northwestern Mutual Life Insurance Company and its subsidiary as of December
31, 1997 and 1996, and the related consolidated statements of operations, of
changes in general contingency reserve and of cash flows for each of the three
years in the period ended December 31, 1997. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements 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 report dated January 24, 1996, we expressed an opinion that the 1995
consolidated financial statements, prepared using accounting practices
prescribed or permitted by the Insurance Departments of the states in which the
Company and its subsidiary were domiciled (statutory basis of accounting), were
presented fairly, in all material respects, in conformity with generally
accepted accounting principles. As described in Note 1 to these financial
statements, pursuant to the pronouncement of the Financial Accounting Standards
Board, financial statements of mutual life insurance enterprises prepared using
accounting practices prescribed or permitted by insurance regulators (statutory
basis of accounting) are no longer considered presentations in conformity with
generally accepted accounting principles. Accordingly, our present opinion on
the presentation of the 1995 financial statements, as presented herein, is
different from that expressed in our previous report.
 
As described in Note 1, these consolidated financial statements were prepared in
conformity with accounting practices prescribed or permitted by the Office of
the Commissioner of Insurance of the State of Wisconsin (statutory basis of
accounting), which practices differ from generally accepted accounting
principles. Accordingly, the consolidated financial statements are not intended
to represent a presentation in accordance with generally accepted accounting
principles. The effects on the consolidated financial statements of the
variances between the statutory basis of accounting and generally accepted
accounting principles, although not reasonably determinable, are presumed to be
material.
 
In our opinion, the consolidated financial statements audited by us (1) do not
present fairly in conformity with generally accepted accounting principles, the
financial position of The Northwestern Mutual Life Insurance Company and its
subsidiary at December 31, 1997 and 1996, or the results of their operations or
their cash flows for each of the three years in the period ended December 31,
1997 because of the effects of the variances between the statutory basis of
accounting and generally accepted accounting principles referred to in the
preceding paragraph and (2) do present fairly, in all material respects, the
financial position of The Northwestern Mutual Life Insurance Company and its
subsidiary at December 31, 1997 and 1996 and the results of their operations and
their cash flows for each of the three years in the period ended December 31,
1997, on the basis of accounting described in Note 1.

 APPENDIX

   
ILLUSTRATIONS OF DEATH BENEFITS, CASH VALUES AND ACCUMULATED PREMIUMS. The
tables on the following pages illustrate how the death benefit and cash value
for a Whole Life Policy, an Extra Ordinary Life Policy and a Single Premium Life
Policy would vary over time based on hypothetical investment results. The tables
assume gross (after tax) investment return rates of 0%, 6% and 12% on assets of
the Fund. The Policies illustrated are for male insureds, select risks, age 35.
The illustration for the Whole Life Policy is on page 43. The illustrations for
Extra Ordinary Life Policies are on pages 44 through 46. The illustration for
the Single Premium Life Policy is on page 47.
    


The death benefits and cash values would be different from those shown if the
gross investment return rate averaged 0%, 6% or 12%, but fluctuated over and
under the average rate at various points in time. The values would also be
different, depending on the Account divisions selected by the owner of the
Policy, if the return rate for the nine Fund Portfolios averaged 0%, 6% or 12%,
but the rates for each individual Portfolio varied over and under the average.


   
The amounts shown as the death benefits and cash values reflect the deductions
from premiums, the charge at the annual rate of .50% of the Account's assets for
mortality and expense risks and the charge at the annual rate of .20% of the
Account's assets for taxes. The amounts shown as the cash values for the Single
Premium Life Policy reflect the deduction for sales costs during the first ten
Policy years. The amounts shown also reflect the average of the investment
advisory fees and the other Fund expenses applicable to each of the nine
Portfolios of the Fund during 1997 at the annual rate of .45% of the Fund's net
assets.  See "Deductions and Charges", p. 7. Thus the 0%, 6% and 12% gross
hypothetical return rates on the Fund's assets are equivalent to the net rates
of -1.15%, 4.85% and 10.85% on the assets of the Account.
    


The second column of each table shows the amount which would accumulate if an
amount equal to the annual or single premium were invested to earn interest,
after taxes, at the stated interest rate compounded annually.


   
The death benefits and corresponding cash values shown for paid-up additions
purchased with dividends illustrate benefits which would be paid if investment
returns of 0%, 6% and 12% are realized, if mortality and expense experience in
the future is as currently experienced and if the current dividend scale remains
unchanged. See "Annual Dividends," p. 13.  HOWEVER, THERE IS NO GUARANTEE AS TO
THE AMOUNT OF DIVIDENDS, IF ANY, THAT WILL BE PAID UNDER A POLICY. Although the
tables are based on the assumption that dividends will be used to purchase
additional paid-up death benefits, other dividend options are available. The
Extra Ordinary Life Policy is designed for a purchaser who intends to use all
dividends to purchase paid-up additions. See "Extra Ordinary Life Policy," p.
11.
    


A comparable illustration based on a proposed insured's age, sex and risk
classification and proposed face amount or premium is available upon request.

(1)  Extra Life Protection is guaranteed to be at least $40,000 for 27 years, so
     long as all premiums are paid when due, no policy loan is outstanding, all
     dividends are applied to purchase paid-up additions and no paid-up
     additions are surrendered for their cash value. Extra Life Protection is
     the sum of any positive variable insurance amount plus variable paid-up
     additions plus term insurance.

(2)  If premiums were paid monthly, the monthly payments would be $89.10. The
     death benefit and cash values would not be affected.

(3)  Assumes no policy loan has been made.

(4)  After the guaranteed period of 27 years for Extra Life Protection, the
     amount of term insurance depends on the dividend scale. The amount
     illustrated is based on current scale and experience and is not guaranteed.

(1)  Extra Life Protection is guaranteed to be at least $40,000 for 27 years, so
     long as all premiums are paid when due, no policy loan is outstanding, all
     dividends are applied to purchase paid-up additions and no paid-up
     additions are surrendered for their cash value. Extra Life Protection is
     the sum of any positive variable insurance amount plus variable paid-up
     additions plus term insurance.

(2)  If premiums were paid monthly, the monthly payments would be $89.10. The
     death benefit and cash values would not be affected.

(3)  Assumes no policy loan has been made.

(4)  After the guaranteed period of 27 years for Extra Life Protection, the
     amount of term insurance depends on the dividend scale. The amount
     illustrated is based on current scale and experience and is not guaranteed.

                                     Exhibit C(6)

                                        April 28, 1998


The Northwestern Mutual Life Insurance Company
720 East Wisconsin Avenue
Milwaukee, Wisconsin  53202

Gentlemen:

This opinion is furnished in connection with Post-Effective Amendment No. 20 to
the Registration Statement on Form S-6, Registration No. 2-89972, of
Northwestern Mutual Variable Life Account (File No. 2-89972).  The prospectus
included in Post-Effective Amendment No. 20 ("Prospectus") describes three
variable life insurance policies which are issued in connection with the Account
("Policies"): Whole Life, Extra Ordinary Life Policies and Single Premium Life
Policies.  The Policy forms were prepared under my direction, and I am familiar
with the Registration Statement and Amendments and Exhibits thereto.  In my
opinion:

l.     The illustrations of death benefits included on pages 10, 11 and 12 of
       the Prospectus, based on the assumptions stated in the illustrations,
       are consistent with the provisions of the Policies.

2.     The illustration of the effect of a Policy loan on the death benefit and
       cash value included on page 14, based on the assumptions stated in the
       illustration, is consistent with the provisions of the Policies.

3.     The illustration of reduced paid-up insurance and extended term in-
       surance included on page 15 of the Prospectus, based on the assumptions
       stated in the illustration, is consistent with the provisions of the
       Policies.

4.     The illustrations of cash values and death benefits included on pages 43
       through 47 of the Prospectus, in the Appendix thereto, including the
       amounts shown for the Base Policy and as Paid-Up Additions, based on the
       assumptions stated in the illustrations, are consistent with the provi-
       sions of the Policies and current dividend scale and experience.  The
       rate structure of the Policies has not been designed so as to make the
       relationship between premiums and benefits, as shown in the illustra-
       tions, appear more favorable to a prospective purchaser of a Policy for
       male age 35, than to prospective purchasers of Policies for a male at
       other ages or for a female.

I hereby consent to the use of this opinion as an exhibit to the Registration
Statement and to the reference to my name under the heading "Experts" in the
Prospectus.

Sincerely,

WILLIAM C. KOENIG

William C. Koenig, F.S.A.
