SUMMARY

THE FOLLOWING SUMMARY PROVIDES A BRIEF OVERVIEW OF THE POLICY.  IT OMITS DETAILS
WHICH ARE INCLUDED ELSEWHERE IN THIS PROSPECTUS AND THE ATTACHED FUND PROSPECTUS
AND IN THE TERMS OF THE POLICY.

VARIABLE LIFE INSURANCE

Variable life insurance is cash value life insurance and is similar in many ways
to traditional fixed benefit life insurance.  Both kinds of life insurance
provide an income tax-free death benefit and a cash value that grows
tax-deferred.  Variable life insurance allows the policyowner to direct the
premiums, after certain deductions, among a range of investment options.  The
variable life insurance death benefit and cash value vary to reflect the
performance of the selected investments.

THE ACCOUNT AND ITS DIVISIONS

Northwestern Mutual Variable Life Account is the investment vehicle for the
Policies.  The Account has nine divisions.  The owner of the Policy determines
how net premiums are to be allocated.  The assets of each division are invested
in a corresponding Portfolio of Northwestern Mutual Series Fund, Inc.  The nine
Portfolios are the Index 500 Stock Portfolio, the Select Bond Portfolio, the
Money Market Portfolio, the Balanced Portfolio, the Growth and Income Stock
Portfolio, the Growth Stock Portfolio, the Aggressive Growth Stock Portfolio,
the High Yield Bond Portfolio and the International Equity Portfolio.  The
investment objectives of the Portfolios are briefly described herein.  See "The
Fund", p. 3.  For additional information see the attached prospectus for the
Fund.

THE POLICY

AVAILABILITY LIMITATIONS   The Variable Executive Life Policy has been designed
for use with non-tax qualified executive benefit plans.  The Policy is offered
for use with corporate-sponsored plans where at least five Policies will be
issued, each on the life of a different eligible insured person, and the first
year premium for the group will be at least $250,000.  Exceptions will be
permitted in some cases and additional requirements may apply.  Each case must
be approved at the Home Office of Northwestern Mutual Life.

PREMIUMS  Premiums may be paid at any time and in any amounts, within limits,
but additional premiums will be required to keep the Policy in force if values
become insufficient to pay current charges.

DEATH BENEFIT  The Policy offers a choice of three death benefit options:

- - SPECIFIED AMOUNT (OPTION A)

- - SPECIFIED AMOUNT PLUS POLICY VALUE (OPTION B)

- - SPECIFIED AMOUNT PLUS PREMIUMS PAID (OPTION C)

In each case, the death benefit will be at least the amount needed to meet
federal income tax requirements for life insurance.  The Specified Amount is
selected by the owner when the Policy is purchased and may be increased or
decreased, within limits and subject to conditions, after a Policy is issued.
The minimum amount is $50,000.00.  No minimum death benefit is guaranteed.

CASH VALUE    The cash value of a Policy is not guaranteed and varies daily to
reflect investment experience.  A Policy may be surrendered for its cash value.
The Policy also includes loan and withdrawal provisions.

DEDUCTIONS AND CHARGES

FROM PREMIUMS

  -  Deduction of 3.6% for local, state and federal taxes attributable to
     premiums

  -  Sales load of 15% up to the Target Premium for first Policy year, and 3% of
     all other premiums

FROM POLICY VALUE

  -  Cost of insurance charge deducted monthly, based on the net amount at risk,
     the age, sex and risk classification of the insured, and the Policy
     duration.  Current charges are based on the experience of Northwestern
     Mutual Life.  Maximum charges are based on the 1980 CSO Mortality Tables.

  -  Monthly mortality and expense risk charge. The current charge is at the
     annual rate of .75% (0.06250% monthly rate) of the amount invested in the
     Account for the Policy for the first 10 Policy years, and .30% (0.02500%
     monthly rate) thereafter.  The maximum annual rate is .90% (0.07500%
     monthly rate).

  -  Monthly administrative charge.  The current charge is $15.00 in the first
     Policy year and $5.00 thereafter.  The maximum charge is $15 in the first
     Policy year and $10 thereafter.

  -  Charge for expenses and taxes associated with the Policy loan, if any.  The
     aggregate charge is at the current annual rate of .75% (0.06250% monthly
     rate) of the Policy debt for the first ten Policy years and .20% (0.01667%)
     thereafter.


                                          2
<PAGE>

  -  Any transaction charges that may result from a withdrawal, a transfer, a
     change in the Specified Amount or a change in the death benefit option.
     These charges are currently waived.  The maximum charge is $250 for death
     benefit option changes and $25 for each of the other transactions.

FROM THE FUND

   
  -  A daily charge for investment advisory and other services provided to the
     Fund.  The total Fund expenses vary by Portfolio and currently fall in an
     approximate range of .21% to .77% of assets on an annual basis.

The following table shows the annual expenses for each of the Portfolios of the
Fund, as a percentage of the average net assets of the Portfolio, based on 1997
operations for the Portfolios and their predecessors:

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
insurance policies and annuity contracts through its own field force of
approximately 6,000 full time producing agents.  The Internal Revenue Service
Employer Identification Number of Northwestern Mutual Life is 39-0509570.
    

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 variable life insurance
policies, including the Policies described in this prospectus as well as other
policy series.

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.

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

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.

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.

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.

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.

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.

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.

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.

DETAILED INFORMATION ABOUT THE POLICY

PREMIUMS

The Policy permits premiums to be paid at any time before the Policy anniversary
that is nearest the insured's 95th birthday and in any amounts within the limits
described in this section.

The Specified Amount selected when the Policy is purchased is used to determine
the minimum initial premium.  The minimum initial premium is approximately equal
to three times the initial monthly Cost of Insurance Charge and other
deductions.

A Target Premium is calculated when the Policy is issued and is used in
determining the sales load for the first Policy year.  The Target Premium is
based on the Specified Amount and the age and sex of the insured.

After a Policy is issued, there are no minimum premiums, except that no premium
of less than $25 will be accepted.  The Policy will remain in force during the
insured's lifetime so long as the Policy Value, less the amount of any Policy
debt, is sufficient to pay the monthly cost of insurance charge and other
current charges.

The Policy sets no maximum on premiums, but a premium that would increase the
net amount at risk will be accepted only if the insurance, as increased, will be
within the issue limits of Northwestern Mutual Life, the insured meets the
insurability requirements and the premium is received prior to the anniversary
nearest the insured's 75th birthday.  A premium will not be accepted if it would
disqualify the Policy as life


                                          4

insurance for federal income tax purposes.  See "Tax Considerations", p.10.

DEATH BENEFIT

DEATH BENEFIT OPTIONS  The Policy provides for three death benefit options:

SPECIFIED AMOUNT (OPTION A)  The Specified Amount is selected by the Owner when
the Policy is purchased.

SPECIFIED AMOUNT PLUS POLICY VALUE (OPTION B)  The Policy Value is the
cumulative amount invested, adjusted for investment results, reduced by the
charges for insurance and other expenses.

SPECIFIED AMOUNT PLUS PREMIUMS PAID (OPTION C)
In addition, under any of the Options, the Death Benefit will be increased if
necessary to meet the definitional requirements for life insurance for federal
income tax purposes as discussed below.

Under any of the death benefit options the death benefit will be equal to the
Policy Value at all times on and after the Policy anniversary nearest the 100th
birthday of the insured.

CHOICE OF TESTS FOR TAX PURPOSES  A Policy must satisfy one of two testing
methods to qualify as life insurance for federal income tax purposes.  The
purchaser may choose either the Guideline Premium/Cash Value Corridor Test or
the Cash Value Accumulation Test.  Both tests require the Policy to meet minimum
ratios, or multiples, of death benefit to the Policy Value.  The minimum
multiple decreases as the age of the insured advances.  The choice of testing
methods is made when a Policy is purchased and it may not be changed.

For the Guideline Premium/Cash Value Corridor Test the minimum multiples of
death benefit to the Policy Value are shown below.


                            GUIDELINE PREMIUM/CASH VALUE

For the Cash Value Accumulation Test the minimum multiples of death benefit to
the Policy Value are calculated using net single premiums based on the attained
age of the insured and the Policy's underwriting classification, using a 4%
interest rate.

The Guideline Premium/Cash Value Corridor Test has lower minimum multiples than
the Cash Value Accumulation Test, usually resulting in better cash value
accumulation for a given amount of premium.  But the Guideline Premium/Cash
Value Corridor Test limits the amount of premium that may be paid in each Policy
year.  The Cash Value Accumulation Test has no such annual limitation, and
allows more premium to be paid during the early Policy years.

DEATH BENEFIT CHANGES  After a Policy is issued the Owner may change the death
benefit option, or increase or decrease the Specified Amount, subject to
approval by Northwestern Mutual Life.  Changes are subject to insurability
requirements and issue limits.  A change will not be permitted if it results in
a Specified Amount less than the minimum for a new Policy issued on that date.


A change in the death benefit option, or an increase or decrease in the
Specified Amount, will be effective on the monthly processing date next
following receipt of a written request at the Home Office of Northwestern Mutual
Life.

Administrative charges of up to $250 for a change in the death benefit option,
and up to $25 for each of more than one change in the Specified Amount in a
Policy year, may apply.  Any such charges will be deducted from the Policy
Value.  Northwestern Mutual Life is currently waiving these charges.

A change in the death benefit option, or an increase or decrease in the
Specified Amount, may have important tax effects.  See "Tax Considerations", p.
10. The cost of insurance charge will increase if a change results in


                                          5
<PAGE>

a larger net amount at risk.  See "Charges Against the Policy Value," below.

ALLOCATIONS TO THE ACCOUNT

The initial net premium is placed in the Account on the Policy date.  Net
premiums paid thereafter are placed in the Account on the date received at the
Home Office of Northwestern Mutual Life.  Net premiums are premiums less the
deductions from premiums.  See "Deductions from Premiums", p 6.

Premiums placed in the Account prior to the initial allocation date are invested
in the Money Market Division of the Account.  The initial allocation date is
identified in the Policy and is the later of the date the application is
approved by Northwestern Mutual Life and the date the initial premium is
received at the Home Office of Northwestern Mutual Life.  A different initial
allocation date applies in those states which require a refund of at least the
premium paid during the period when the Policy may be returned.  See "Right to
Return Policy," p. 8.  On the initial allocation date the amount in the Money
Market Division is invested in the Account divisions as directed in the
application for the Policy.  The Policyowner may change the allocation for
future net premiums at any time by written request and the change will be
effective for premiums placed in the Account thereafter.  Allocation must be in
whole percentages.

The Policyowner may transfer accumulated amounts from one division of the
Account to another.  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 of up to $25, to cover administrative
costs of transfers, if there are more than twelve transfers in a Policy year.
Northwestern Mutual Life is currently waiving these charges.

DEDUCTIONS AND CHARGES

DEDUCTIONS FROM PREMIUMS    A charge for taxes attributable to premiums is
deducted from each premium.  The total amount of this deduction is 3.6% of the
premium.  Of this amount 2.35% is for state premium taxes.  Premium taxes vary
from state to state and currently range from .75% to 3.5% of life insurance
premiums.  The 2.35% rate is an average.  The tax rate for a particular state
may be lower, higher, or equal to the 2.35% deduction.  Northwestern Mutual Life
does not expect to profit from this charge.  The remainder of the deduction,
1.25% of each premium, is for federal income taxes measured by premiums.
Northwestern Mutual Life believes that this charge does not exceed a reasonable
estimate of its federal income taxes attributable to the treatment of deferred
acquisition costs.

A charge for sales costs is deducted from each premium.  The charge is 15% of
premiums paid during the first Policy year up to the Target Premium and 3% of
all other premiums.  The Target Premium is based on the Specified Amount and the
age and sex of the insured.  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, any gain realized from
the monthly charge against the Policy Value for the mortality and expense risks
assumed by Northwestern Mutual Life, as described below.

CHARGES AGAINST THE POLICY VALUE    A cost of insurance charge is deducted from
the Policy Value on each  monthly processing date.  The amount is determined by
multiplying the net amount at risk by the cost of insurance rate.  The net
amount at risk is equal to the death benefit currently in effect less the Policy
Value.  The cost of insurance rate reflects the issue age, policy duration and
risk classification of the insured.  The maximum cost of insurance rates are
included in the Policy.

A charge for the mortality and expense risks assumed by Northwestern Mutual Life
is also deducted monthly from the Policy Value.  The maximum amount of the
charge is equal to an annual rate of .90% (0.07500% monthly rate) of the Policy
Value.  Currently the charge is equal to an annual rate of .75% (0.06250%
monthly rate) of Policy Value for the first ten Policy years and .30% (0.0250%
monthly rate) thereafter.  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.

There is a monthly administrative charge of not more than $15 for the first
Policy year and $10 thereafter.  Currently this charge will be $5 after the
first Policy year.  This charge is for administrative expenses, including costs
of premium collection, processing claims, keeping records and communicating with
Policyowners.  Northwestern Mutual Life does not expect to profit from this
charge.

A charge is made for the expenses and taxes associated with the Policy debt, if
any.  The aggregate charge is at the current annual rate of 0.75% (0.06250%
monthly rate) of the Policy debt for the first ten Policy years and 0.20%
(0.01667% monthly rate) thereafter.

The Policy provides for transaction fees to be deducted from the Policy Value on
the dates on which


                                          6
<PAGE>

transactions take place.  These charges are $25 for changes in the Specified
Amount, withdrawals or transfers of assets among the divisions of the Account if
more than twelve transfers take place in a Policy year.  The fee for a change in
the death benefit option is $250.  Currently all of these fees are being waived.

Deductions from the Policy Value will be apportioned among the divisions of the
Account in proportion to the amounts invested in the divisions.

EXPENSES OF THE FUND   The investment performance of each division of the
Account reflects all expenses borne by the corresponding Portfolio of the Fund.
See the attached Fund prospectus for more information about those expenses.

CASH VALUE

The owner of a Policy may surrender it for the cash value at any time during the
lifetime of the insured.  The cash value for the Policy will change daily in
response to investment results. No minimum cash value is guaranteed. The cash
value is equal to the Policy Value reduced by any Policy debt outstanding.
During the first Policy year the cash value is increased by the amount of sales
load previously deducted from premiums, and during the second Policy year the
cash value is increased by 50% of previous sales load deductions.  This increase
in cash value during the first two Policy years does not apply if the Policy is
in a grace period on the date on which the Policy is surrendered.

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 1940, 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.

POLICY LOANS

The owner of a Policy may borrow up to 90% of the Policy Value using the Policy
as security. If a Policy loan is already outstanding, the maximum amount for any
new loan is 90% of the Policy Value, less the amount already borrowed.

Interest on a Policy loan accrues and is payable on a daily basis at an annual
effective rate of 5%. Unpaid interest is added to the amount of the loan. If the
amount of the loan equals or exceeds the Policy Value on a monthly processing
date, the Policy will enter the grace period.  See "Termination and
Reinstatement", below. A notice will be sent to the owner at least 61 days
before the termination date. The notice will show how much must be paid to keep
the Policy in force.

The amount of a Policy loan 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 5% Policy loan
interest rate. A Policy loan, even if it is repaid, will have a permanent effect
on the Policy 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.

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 proportion to the premium allocation in effect, as of the
same date.

A Policy loan may have important tax consequences.  See "Tax Considerations", p.
10.

WITHDRAWALS OF POLICY VALUE

The Policyowner may make a withdrawal of Policy Value. A withdrawal may not
reduce the loan value to less than any Policy debt outstanding. The loan value
is 90% of the Policy Value, less any Policy debt already outstanding.  Following
a withdrawal the remaining Policy Value, less any Policy debt outstanding, must
be at least three times the current monthly charges for the cost of insurance
and other expenses. The minimum amount for withdrawals is $250.  Up to four
withdrawals are permitted in a Policy year. An administrative charge of up to
$25 may apply, but is currently being waived.

A withdrawal of Policy Value decreases the death benefit by the same amount.  If
the death benefit for a Policy has been increased to meet the federal tax
requirements for life insurance, the decrease in the death benefit caused by a
subsequent withdrawal will be larger than the amount of the withdrawal.  If
Option A or Option C is in effect a withdrawal of Policy Value will reduce the
Specified Amount by the amount of the withdrawal.  Following a withdrawal the
remaining death benefit must be at least the minimum amount that Northwestern
Mutual Life would currently issue.

The amount withdrawn from Policy Value will be taken from the Account divisions
in proportion to the amounts in the divisions. The Policy makes no


                                          7
<PAGE>

provision for repayment of amounts withdrawn.  A withdrawal of Policy Value may
have important tax consequences.  See "Tax Considerations", p. 10.

TERMINATION AND REINSTATEMENT

If the Policy Value, less any Policy debt outstanding, is less than the monthly
charges for the cost of insurance and other expenses on any monthly processing
date, a grace period of 61 days is allowed for the payment of sufficient premium
to keep the Policy in force.  The grace period begins on the date that a notice
is sent to the Policyowner.  The notice will state the minimum amount of premium
required to keep the Policy in force and the date by which the premium must be
paid.  The Policy will terminate unless the required amount is paid before the
grace period expires.

After a Policy has terminated, it may be reinstated within one year.  The
insured must provide satisfactory evidence of insurability.  The minimum amount
of premium required for reinstatement will be the monthly charges that were due
when the Policy terminated plus the charges for three more months.

Reinstatement of a Policy will be effective on the first monthly processing date
after an application for reinstatement is received at the Home Office of
Northwestern Mutual Life, subject to approval by Northwestern Mutual Life.  Any
Policy debt that was outstanding when the Policy terminated will also be
reinstated.

The Policy Value when a Policy is reinstated is equal to the premium paid, after
the deduction for taxes and sales load, less the sum of all monthly charges for
the cost of insurance and other expenses for the grace period and for the
current month.  The Policy Value will be allocated among the Account divisions
based on the allocation for premiums currently in effect.

A Policy may not be reinstated after the Policy has been surrendered for its
cash value.

See "Tax Considerations", p. 10, for a discussion of the tax effects associated
with termination and reinstatement of a Policy.

RIGHT TO RETURN POLICY

A Policy may be returned within 45 days after the application for insurance is
signed or within 10 days (or later where required by state law) after the Policy
is received, whichever is later.  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.  Northwestern
Mutual Life will refund the sum of the amounts deducted from the premium paid
plus the value of the Policy in the Account on the date the returned Policy is
received.  In some states, the amount refunded will not be less than the premium
paid.

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
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.  An increase in the amount of insurance that was subject to
insurability requirements will not be contested after the increased amount has
been in force during the lifetime of the insured for two years from the date of
issuance of the increase.

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, less
the amount of any Policy debt and withdrawals.  If the insured dies by suicide
within one year of the date of issuance of an increase in the amount of
insurance, which was subject to insurability requirements, the amount payable
with respect to the increase will be limited to the amounts charged for the cost
of insurance and other expenses attributable to the increase.

MISSTATEMENT OF AGE OR SEX.  If the age or sex of the insured has been
misstated, the charges for cost of insurance and other expenses 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.

DEFERRAL OF DETERMINATION AND PAYMENT.  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


                                          8
<PAGE>

the Securities and Exchange Commission, by order, permits deferral for the
protection of Policyowners.

DIVIDENDS.  The Policies will share in divisible surplus to the extent
determined annually by Northwestern Mutual Life.  Since the Policies are not
expected to contribute to divisible surplus, it is not expected that any
dividends will be paid.

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 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

At least once each Policy year the owner of a Policy will receive a statement
showing the death benefit, Policy Value and any Policy loan, including loan
interest. This report will show the apportionment of invested assets among the
Account divisions.  Owners will also receive annual and semiannual reports for
the Account and the Fund, including financial statements.

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.  NMIS was organized in 1968 
as a Wisconsin corporation. Its address is 720 East Wisconsin Avenue, 
Milwaukee, Wisconsin 53202. The Internal Revenue Service Employer 
Identification Number of NMIS is 39-1099296.
    

Commissions paid to the agents will not exceed 15% of the premium for the first
year and 2-3/4% of the premium thereafter. During the sixth Policy year and
thereafter agents will receive compensation at the annual rate of .20% of the
cash value of a Policy.

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 CONSIDERATIONS

GENERAL  The following discussion provides a general description of federal
income tax consideration relating to the Policy.  The discussion is based on
current provisions of the Internal Revenue Code ("Code") as currently
interpreted by the Internal Revenue Service.  This discussion is not intended as
tax advice.  The discussion is not exhaustive, it does not address the
likelihood of future changes in federal income tax law or interpretations
thereof, and it does not address state or local tax considerations which may be
significant in the purchase and ownership of a Policy.

LIFE INSURANCE QUALIFICATION  Section 7702 of the Code defines life insurance
for federal income tax purposes.  The Code provides two alternative tests for
determining whether the death benefit is a sufficient multiple of the Policy
Value.  See "Choice of Tests for Tax Purposes", p. 5.  The Policy is designed to
comply with these rules.  Premiums that would cause a Policy to be disqualified
as life insurance will be returned.

Section 817(h) of the Code authorizes the Secretary of the Treasury to set
standards for diversification of the investments underlying variable life
insurance policies.  Final regulations have been issued pursuant to this
authority.  Failure to meet the diversification requirements would disqualify
the Policies as life insurance for purposes of Section 7702 of the Code.
Northwestern Mutual Life intends to comply with these requirements.

The Treasury Department, in connection with the diversification requirements,
stated that it expected to issue guidance about circumstances where a
policyowner's control of separate account assets would cause the policyowner,
and not the life insurance company, to be treated as the owner of those assets.
These guidelines have not been issued.  If the owner of a Policy were treated as
the owner of the Fund shares held in the Account, the income and gains related
to those shares would be included in the owner's gross income for federal income
tax purposes.  Northwestern Mutual Life believes that it owns the assets of the
Account under current federal income tax law.

TAX TREATMENT OF LIFE INSURANCE   While a Policy is in force, increases in the
Policy Value as a result of investment experience are not subject to federal
income tax until there is a distribution as defined by the Code.  The death
benefit received by a beneficiary will not be subject to federal income tax.

Unless the Policy is a modified endowment contract, as described below,
Northwestern Mutual Life believes that a loan received under a Policy will be
construed as indebtedness of the owner and no part of the loan will be treated
as a distribution subject to current federal income tax.  Interest paid by
individual owners of the Policies will ordinarily not be deductible.  A
qualified tax adviser should be consulted as to the deductibility of interest
paid, or accrued, by other purchasers of the Policies.  See "Other Tax
Considerations", below.

As a general rule, the proceeds from a withdrawal of Policy Value will be
taxable only to the extent that the withdrawal exceeds the basis of the Policy.
The basis of the Policy is generally equal to the premiums paid less any amounts
previously received as tax-free distributions.  In certain circumstances, a
withdrawal of Policy Value during the first 15 Policy years may be taxable to
the extent that the Policy Value exceeds the basis of the Policy. This means
that the amount withdrawn may be taxable even if that amount is less than the
basis of the Policy.  In addition, if a Policy terminates while a Policy loan is
outstanding, the cancellation of the loan and accrued interest will be treated
as a distribution from the Policy and may be taxable under these rules.

Special tax rules may apply when ownership of a Policy is transferred.
Qualified tax advice should be sought when a transfer of ownership is planned.

MODIFIED ENDOWMENT CONTRACTS  A Policy will be classified as a modified
endowment contract if the cumulative premium paid during the first seven Policy
years exceeds a defined "seven-pay" limit.  The seven-pay limit is based on a
hypothetical life insurance policy issued on the same insured person and for the
same initial death benefit which, under specified conditions (which include the
absence of expense and administrative charges) will be fully paid for after
seven level annual payments.  A Policy will be treated as a modified endowment
contract unless cumulative premiums paid under the Policy, at all times during
the first seven Policy years, are less than or equal to the cumulative seven-pay
premiums which would have been paid under the hypothetical policy on or before
such times.

Whenever there is a "material change" under a Policy, it will generally be
treated as a new contract for purposes of determining whether the Policy is a
modified endowment contract, and subjected to a new seven-pay period and a new
seven-pay limit.  The new seven-pay limit would be determined taking into
account the Policy Value of the Policy at the time of such change.  A materially
changed Policy would be considered a modified endowment contract if it failed to
satisfy the new seven-pay limit.  A material change could occur as a result of a
change in the death benefit option, a change in the Specified Amount, and
certain other changes.


                                          10
<PAGE>

If the benefits are reduced during the first seven Policy years after entering
into the Policy (or within seven years after a material change), for example, by
requesting a decrease in the Specified Amount or, in some cases, by making a
withdrawal of Policy Value, the seven-pay premium limit will be redetermined
based on the reduced level of benefits and applied  retroactively for purposes
of the seven-pay test.  If the premiums previously paid are greater than the
calculated seven-pay premium level limit, the Policy will become a modified
endowment contract.  A life insurance policy which is received in exchange for a
modified endowment contract will also be considered a modified endowment
contract.

If a Policy is a modified endowment contract, any distribution from the Policy
will be taxed on a gain- first basis.  Distributions for this purpose include a
loan (including any increase in the loan amount to pay interest on an existing
loan or an assignment or a pledge to secure a loan) or a withdrawal of Policy
Value.  Any such distributions will be considered taxable income to the extent
the Policy Value exceeds the basis in the Policy.  For modified endowment
contracts, the basis would be increased by the amount of any prior loan under
the Policy that was considered taxable income.  For purposes of determining the
taxable portion of any distribution, all modified endowment contracts issued by
Northwestern Mutual Life to the same policyowner (excluding certain qualified
plans) during any calendar year are to be aggregated.  The Secretary of the
Treasury has authority to prescribe additional rules to prevent avoidance of
gain-first taxation on distributions from modified endowment contracts.

A 10% penalty tax will apply to the taxable portion of a distribution from a
modified endowment contract.  The penalty tax will not, however, apply to
distributions (i) to taxpayers 59 1/2 years of age or older, (ii) in the case of
a disability (as defined in the Code) or (iii) received as part of a series of
substantially equal periodic annuity payments for the life (or life expectancy)
of the taxpayers or the joint lives (or joint life expectancies) of the taxpayer
and his beneficiaries.  If a Policy is surrendered, the excess, if any, of the
Policy Value over the basis of the Policy will be subject to federal income tax
and, unless one of the above exceptions applies, the 10% penalty tax.  The
exceptions generally do not apply to life insurance policies owned by
corporations or other entities.  If a Policy terminates while there is a Policy
loan, the cancellation of the loan and accrued loan interest will be treated as
a distribution to the extent not previously treated as such and could be subject
to tax, including the penalty tax, as described under the above rules.

If a Policy becomes a modified endowment contract, distributions that occur
during the Policy year it becomes a modified endowment contract and any
subsequent Policy year will be taxed as described in the two preceding
paragraphs.  In addition, distributions from a Policy within two years before it
becomes a modified endowment contract will be subject to tax in this manner.
This means that a distribution made from a Policy that is not a modified
endowment contract could later become taxable as a distribution from a modified
endowment contract.  The Secretary of the Treasury has been authorized to
prescribe rules which would treat similarly other distributions made in
anticipation of a policy becoming a modified endowment contract.

OTHER TAX CONSIDERATIONS  Business-owned life insurance may be subject to
certain additional rules.  Section 264(a)(1) of the Code generally disallows a
deduction for premiums paid on Policies by anyone who is directly or indirectly
a beneficiary under the Policy.  Increases in Policy Value may also be subject
to tax under the corporation alternative minimum tax provisions.

Section 264(a)(4) of the Code limits the Policyowner's deduction for interest on
loans taken against life insurance policies to interest on an aggregate total of
$50,000 of loans per covered life only with respect to life insurance policies
covering key persons.  Generally, a key person means an officer or a 20% owner.
However, the number of key persons will be limited to the greater of (a) five
individuals, or (b) the lesser of 5% of the total officers and employees of the
taxpayer or 20 individuals.  Deductible interest for these Policies will be
subject to limits based on current market rates.

In addition, Section 264(f) disallows a proportionate amount of a business'
interest deduction based on the amount of unborrowed cash value of non-exempt
life insurance policies held in relation to other business assets.  Exempt
policies include policies held  by natural persons unless the business is a
direct or indirect beneficiary under the policy and policies owned by a business
and insuring employees, directors, officers and 20% owners (as well as joint
policies insuring 20% owners and their spouses).

Finally, life insurance subject to a split dollar arrangement is taxable to the
employee in the amount of the annual value of the economic benefit to the
employee measured by the issuer's lowest one-year term rates as defined by
various Internal Revenue Service rulings or the government's P.S. 58 table
rates.  The Internal Revenue Service has also ruled in a private letter ruling
related to a specific taxpayer under audit that the accrued earnings in the
equity split dollar policies held by the taxpayer were taxable in the year
earned.  The Internal Revenue Service has not issued a


                                          11
<PAGE>

formal ruling on this issue and is currently reviewing the taxation of split
dollar arrangements generally.

Depending on the circumstances, the exchange of a Policy, a change in the death
benefit option, a Policy loan, a withdrawal of Policy Value, a change in
ownership or an assignment of the Policy may have federal income tax
consequences.  In addition, federal, state and local transfer, estate,
inheritance, and other tax consequences of Policy ownership, premium payments
and receipt of Policy proceeds depend on the circumstances of each Policyowner
or beneficiary.  Any person contemplating any such transaction should consult a
qualified tax adviser.

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>

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

                        DECEMBER 31, 1997, 1996 AND 1995
 
CASH AND TEMPORARY INVESTMENTS
 
Temporary investments consist of debt securities that have maturities of one
year or less at acquisition.
 
NET INVESTMENT INCOME
 
Net investment income includes interest and dividends received or due and
accrued on debt securities and stocks, equity in unconsolidated subsidiaries'
earnings and the Company's prorated portion of joint venture income. Net
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 made to 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
$4 million.
 
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
on 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 Policy would vary over time based on hypothetical investment results. The
tables assume gross investment return rates of 0%, 6% and 12% on assets of the
Account. The Policies illustrated are on a sex-neutral basis, age 45, $500,000
Specified Amount and death benefit Option A with a $10,000 annual planned
premium.  The first four illustrations, on pages 37 - 40 are for a policy issued
to a guaranteed issue, non-Tobacco risk using 1) the guideline premium/cash
value corridor test, and 2) the cash value accumulation test for the definition
of life insurance, based on both current charges and on maximum charges.  The
next four illustrations are for a policy issued to a select risk using the two
different definition of life insurance tests and based on both current charges
and on maximum charges.

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 and deductions from Policy Value.  The amounts shown 
as the cash values reflect the fact that the Company will refund a portion of 
the sales load for a policy surrendered during the first two years. The 
amounts shown also reflect the average of the  investment advisory fees and  
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 "The 
Fund", p. 3. Thus the 0%, 6% and 12% gross hypothetical return rates on the 
Fund's assets are equivalent to the net rates of -.45%, 5.55% and 11.55% 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  premium were invested to earn interest, after taxes,
at a 5% interest rate compounded annually.

   
The death benefits and corresponding cash values shown on pages 37, 39, 41 and
43 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.  HOWEVER, CURRENT MONTHLY COST OF INSURANCE AND EXPENSE
CHARGES MAY CHANGE SUBJECT TO THE STATED MAXIMUM CHARGES.
    

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

THE VARIABLE ACCOUNT.

THE DEATH BENEFIT AND CASH VALUE FOR A POLICY WOULD BE DIFFERENT FROM THOSE

                             UNDERTAKING TO FILE REPORTS

     Subject to the terms and conditions of Section 15(d) of the Securities
Exchange Act of 1934, the undersigned registrant hereby undertakes to file with
the Securities and Exchange Commission such supplementary and periodic
information, documents, and reports as may be prescribed by any rule or
regulation of the Commission heretofore or hereafter duly adopted pursuant to
authority conferred in that section.

                     UNDERTAKING WITH RESPECT TO INDEMNIFICATION

     Reference is made to the indemnification provisions contained in Article
VII of the By-laws of the Depositor, The Northwestern Mutual Life Insurance
Company, cited as part of Exhibit A(6)(a) to the Registration Statement, and
previously filed in electronic format as EX-99.A.6 on April 26, 1996 with Post
Effective Amendment No. 18 on Form S-6 to the Registration Statement for
Northwestern Mutual Variable Life Account, File No. 2-89972.  Insofar as
indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                   REPRESENTATION WITH RESPECT TO FEES AND CHARGES

     The Northwestern Mutual Life Insurance Company hereby represents that the
fees and charges deducted under the contracts registered by this registration
statement, in the aggregate, are reasonable in relation to the services
rendered, the expenses expected to be incurred, and the risks assumed by the
insurance company.

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

Gentlemen:

     This opinion is furnished in connection with Pre-Effective Amendment No. 2
to the Registration Statement on Form S-6, Registration No. 333-36865, of
Northwestern Mutual Variable Life Account. The prospectus included in the
Registration Statement ("Prospectus") describes the Flexible Premium Variable
Life Insurance Policy to be issued in connection with the Account ("Policy").
The Policy form was prepared under my direction, and I am familiar with the
Registration Statement and Exhibits thereto.  In my opinion:

   
1.   The illustrations of cash values and death benefits included on pages 37
     through 44 of the Prospectus, in the Appendix thereto, based on the
     assumptions stated in the illustrations, are consistent with the provisions
     of the Policies and current charges and experience.  The Policy has not
     been designed so as to make the illustration appear more favorable for a
     prospective purchaser, age 45 on the sex-neutral basis shown, than for
     purchasers at other ages on a sex-neutral basis or for a male or a female.
    

2.   With respect to the charge of 1.25% of premiums for federal income taxes
     measured by premiums, described on page 6 of the Prospectus,

     (a)  the charge is reasonable in relation to the issuer's increased federal
          tax burden under Section 848 of the Internal Revenue Code of 1986;

     (b)  the targeted rate of return (11%) used in calculating the charge is
          reasonable; and

     (c)  the factors taken into account in determining such targeted rate of
          return are appropriate.

     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
