Funds. The prospectuses for these mutual funds, attached to this prospectus,

The values provided by the Policy vary daily depending on investment results.
These values are not guaranteed. The Portfolios and Funds present varying
degrees of investment risk.

SUMMARY


The following summary provides a brief overview of the Policy. It omits details
which are included elsewhere in this prospectus and the attached mutual fund
prospectuses 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 sixteen divisions. You determine how net premiums are
to be apportioned. We invest the assets of each division in a corresponding
Portfolio of Northwestern Mutual Series Fund, Inc. or one of the Russell
Insurance Funds. The eleven Portfolios of Northwestern Mutual Series Fund, Inc.
are the Small Cap Growth Stock Portfolio, Aggressive Growth Stock Portfolio,
International Equity Portfolio, Index 400 Stock 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 five Russell Insurance Funds are the Multi-Style Equity
Fund, Aggressive Equity Fund, Non-U.S. Fund, Real Estate Securities Fund, and
Core Bond Fund. For additional information about the funds see the attached
prospectuses.

THE POLICY


AVAILABILITY LIMITATIONS We have designed the Variable Executive Life Policy for
use with non-tax qualified executive benefit plans. We offer the Policy 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 $75,000. We will permit exceptions in some cases
and additional requirements may apply. Each case must be approved at our Home
Office.


PREMIUMS You may pay premiums 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. You select the Specified
Amount when you purchase the Policy. You may increase or decrease the Specified
Amount, 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. You may surrender a Policy 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, 6.8%
         of premiums up to the Target Premium for Policy years 2-6, and 3% of
         all other premiums. The Target Premium is based on the modified
         endowment contract seven-pay limit for the Specified Amount and the age
         and sex of the insured. See "Modified Endowment Contracts", p. 12. A
         Policy receiving the 3% deduction in the first Policy year on any
         portion of the premium will be classified as a modified endowment
         contract.

FROM POLICY VALUE

         annual rate of .75% (0.06250% monthly rate) of the Policy Value, less
         any Policy debt, for the first 10 Policy years, and .30% (0.02500%
         monthly rate) thereafter. The maximum annual rate is .90% (0.07500%
         monthly rate).

- - -        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. We are currently waiving these charges. The maximum charge is
         $250 for death benefit option changes and $25 for each of the other
         transactions.


FROM THE MUTUAL FUNDS


- - -         A daily charge for investment advisory and other services provided to
          the mutual funds. The total expenses vary by Portfolio or Fund and

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



NORTHWESTERN MUTUAL

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 $85 billion on December 31, 1999, 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 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 is 39-0509570.

"We" in this prospectus means Northwestern Mutual.


THE ACCOUNT

We established Northwestern Mutual Variable Life Account by action of our
Trustees 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 our other income, gains or losses. We use the Account
only for variable life insurance policies, including other variable life
insurance policies which are described in other prospectuses.

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

THE FUNDS

NORTHWESTERN MUTUAL SERIES FUND, INC.

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. The Account buys shares of each Portfolio at
their net asset value without any sales charge.


The investment adviser for the Fund is Northwestern Mutual Investment Services,
LLC ("NMIS"), our wholly-owned subsidiary. 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 .79% for the Small Cap Growth Stock
Portfolio, based on 1999 asset size. Other expenses borne by the Portfolios
range from 0% for the Select Bond, Money Market and Balanced Portfolios to .21%
for the Small Cap Growth Stock Portfolio. We provide the people and facilities
NMIS uses in performing its investment advisory functions and we are a party to
the investment advisory agreement. NMIS has retained J.P. Morgan Investment
Management, Inc. and Templeton Investment Counsel, Inc. under investment sub-
advisory agreements to provide investment advice to the Growth and Income Stock
Portfolio and the International Equity Portfolio.


The investment objectives and types of investments for each of the eleven
Portfolios of the Fund are set forth below. There can be no assurance that the
Portfolios will realize their objectives. For more information about the
investment objectives and policies, the attendant risk factors and expenses see
the attached prospectus for Northwestern Mutual Series Fund, Inc.

SMALL CAP GROWTH STOCK PORTFOLIO. The investment objective of the Small Cap
Growth Stock Portfolio is long-term growth of capital. The Portfolio will seek
to achieve this objective primarily by investing in the common stocks of
companies which can reasonably be expected to increase sales and earnings at a
pace which will exceed the growth rate of the U.S. economy over an extended
period.

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.

INDEX 400 STOCK PORTFOLIO. The investment objective of the Index 400 Stock
Portfolio is to achieve investment results that approximate the performance of
the Standard & Poor's MidCap 400 Index ("S&P 400 Index"). The Portfolio will
attempt to meet this objective by investing in stocks included in the S&P 400
Index.

                                       4

<PAGE>   10


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
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.

RUSSELL INSURANCE FUNDS

The Russell Insurance Funds also comprise a mutual fund of the series type
registered under the Investment Company Act of 1940 as an open-end diversified
management investment company. The Account buys shares of each of the Russell
Insurance Funds at their net asset value without any sales charge.

The assets of each of the Russell Insurance Funds are invested by one or more
investment management organizations researched and recommended by Frank Russell
Company ("Russell"), and an affiliate of Russell, Frank Russell Investment
Management Company ("FRIMCo"). FRIMCo also advises, operates and administers the
Russell Insurance Funds. Russell is our majority-owned subsidiary.

The investment objectives and types of investments for each of the five Russell
Insurance Funds are set forth below. There can be no assurance that the Funds
will realize their objectives. A table showing the expense ratios for each of
the Russell Insurance Funds is included in the Summary above, at page 3. For
more information about the investment objectives and policies, the attendant
risk factors and expenses see the attached prospectus for the Russell Insurance
Funds.

MULTI-STYLE EQUITY FUND. The investment objective of the Multi-Style Equity Fund
is to provide income and capital growth by investing principally in equity
securities. The Multi-Style Equity Fund invests primarily in common stocks of
medium and large capitalization companies. These companies are predominately
US-based, although the Fund may invest a limited portion of its assets in non-US
firms from time to time.

AGGRESSIVE EQUITY FUND. The investment objective of the Aggressive Equity Fund
is to provide capital appreciation by assuming a higher level of volatility than
is ordinarily expected from Multi-Style Equity Fund by investing in equity
securities. The Aggressive Equity Fund invests primarily in common stocks of
small and medium capitalization companies. These companies are predominately
US-based, although the Fund may invest in non-US firms from time to time.

NON-U.S. FUND. The investment objective of the Non-U.S. Fund is to provide
favorable total return and additional diversification for US investors by
investing primarily in equity and fixed-income securities of non-US companies,
and securities issued by non-US governments. The Non-U.S. Fund invests primarily
in equity securities issued by companies domiciled outside the United States and
in depository receipts, which represent ownership of securities of non-US
companies.

REAL ESTATE SECURITIES FUND. The investment objective of the Real Estate
Securities Fund is to generate a high level of total return through above
average current income, while maintaining the potential


                                       5

<PAGE>   11



for capital appreciation. The Fund seeks to achieve its objective by
concentrating its investments in equity securities of issuers whose value is
derived primarily from development, management and market pricing of underlying
real estate properties.

CORE BOND FUND. The investment objective of the Core Bond Fund is to maximize
total return, through capital appreciation and income, by assuming a level of
volatility consistent with the broad fixed-income market, by investing in
fixed-income securities. The Core Bond Fund invests primarily in fixed-income
securities. In particular, the Fund holds debt securities issued or guaranteed
by the US government, or to a lesser extent by non-US governments, or by their
respective agencies and instrumentalities. It also holds mortgage-backed
securities, including collateralized mortgage obligations. The Fund also invests
in corporate debt securities and dollar-denominated obligations issued in the US
by non-US banks and corporations (Yankee Bonds). A majority of the Fund's
holdings are US dollar-denominated. From time to time the Fund may invest in
municipal debt obligations.


DETAILED INFORMATION ABOUT THE POLICY


PREMIUMS

The Policy permits you to pay premiums 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.


We use the Specified Amount you select when you purchase the Policy to determine
the minimum initial premium. The minimum initial premium varies with the issue
age and sex of the insured.


We calculate a Target Premium when the Policy is issued and we use the Target
Premium to determine the sales load. The Target Premium is based on the modified
endowment contract seven-pay limit for the Specified Amount and the age and sex
of the insured.

After a Policy is issued, there are no minimum premiums, except that we will not
accept a premium of less than $25. 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 we will accept a premium that would
increase the net amount at risk only if the insurance, as increased, will be
within our issue limits, the insured meets our insurability requirements and we
receive the premium prior to the anniversary nearest the insured's 75th
birthday. We will not accept a premium if it would disqualify the Policy as life
insurance for federal income tax purposes. We will accept a premium, however,
even if it would cause the Policy to be classified as a modified endowment
contract. See "Tax Considerations", p. 11.

DEATH BENEFIT

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

Specified Amount (Option A)  You select the Specified Amount when you purchase
the Policy.

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, we will increase the Death Benefit 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. You 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. You make the choice of testing methods when
you purchase a Policy and it may not be changed.

                                       6

<PAGE>   12


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

</TABLE>

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 we issue a Policy you may change the death benefit
option, or increase or decrease the Specified Amount, subject to our approval.
Changes are subject to insurability requirements and issue limits. We will not
permit a change if it results in a Specified Amount less than the minimum for a
new Policy that we would issue 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 our Home Office.

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. We will deduct any such charges from the Policy Value.
We are 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.
11. The cost of insurance charge will increase if a change results in a larger
net amount at risk. See "Charges Against the Policy Value," below.

ALLOCATIONS TO THE ACCOUNT

We place the initial net premium in the Account on the Policy date. Net premiums
you pay thereafter are placed in the Account on the date we receive them at our
Home Office. Net premiums are premiums less the deductions from premiums. See
"Deductions from Premiums," below.

We invest premiums we place in the Account prior to the initial allocation date
in the Money Market Division of the Account. The initial allocation date is
identified in the Policy and is the later of the date we approved the
application and the date we received the initial premium at our Home Office. 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.
In those states, the initial allocation date will be one day after the end of
the period during which the policyowner has the right to return the Policy,
based on the applicable state laws. See "Right to Return Policy", p. 10. On the
initial allocation date we invest the amount in the Money Market Division in the
Account divisions as you have directed in the application for the Policy. You
may change the allocation for future net premiums at any time by written request
and the change will be effective for premiums we place in the Account
thereafter. Allocation must be in whole percentages.

You may transfer accumulated amounts from one division of the Account to
another. Transfers are effective on the date we receive a written request at our
Home Office. We reserve 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. We are currently waiving these charges.

DEDUCTIONS AND CHARGES


DEDUCTIONS FROM PREMIUMS We deduct a charge for taxes attributable to premiums
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. This



                                       7

<PAGE>   13




2.35% rate is an average rate since premium tax rates vary from state to state
(they currently range from .5% to 3.5% of life insurance premiums.) We do 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. We believe that this
charge does not exceed a reasonable estimate of our federal income taxes
attributable to the treatment of deferred acquisition costs. We may change the
charge for taxes to reflect any changes in the law.


We deduct a charge for sales costs from each premium. The charge is 15% of
premiums paid during the first Policy year up to the Target Premium, 6.8% of
premiums paid during each of Policy years 2-6 up to the Target Premium, and 3%
of all other premiums. The Target Premium is based on the modified endowment
contract seven-pay limit for the Specified Amount and the age and sex of the
insured. See "Modified Endowment Contracts", p. 12. To the extent that sales
expenses exceed the amounts deducted, we will pay the expenses from our 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 we
have assumed, as described below.

CHARGES AGAINST THE POLICY VALUE We deduct a cost of insurance charge from the
Policy Value on each monthly processing date. We determine the amount 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.

We also deduct a charge for the mortality and expense risks we have assumed. The
maximum amount of the charge is equal to an annual rate of .90% (0.07500%
monthly rate) of the Policy Value, less any Policy debt. Currently the charge is
equal to an annual rate of .75% (0.06250% monthly rate) of Policy Value, less
any Policy debt, 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 we
estimated. The expense risk is that expenses of issuing and administering the
Policies may exceed the estimated costs. We will realize a gain from this charge
to the extent it is not needed to provide benefits and pay expenses under the
Policies.

We deduct 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. We do not expect to profit from this charge.

We deduct a charge 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 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 we are waiving all
of these fees.

We will apportion deductions from the Policy Value among the divisions of the
Account in proportion to the amounts invested in the divisions.

EXPENSES OF THE FUNDS The investment performance of each division of the Account
reflects all expenses borne by the corresponding Portfolio or Fund. The expenses
are summarized above on page 3. See the attached mutual fund prospectuses for
more information about those expenses.

POLICIES ISSUED PRIOR TO NOVEMBER 8, 1999 For Policies issued prior to November
8, 1999, including Policies issued after that date in states where the current
Policy form has not been approved, the deduction from premiums for sales costs
is 15% of premiums paid during the first Policy year up to the Target Premium
and 3% of all other premiums.

CASH VALUE

You may surrender a Policy 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, during the second Policy year the cash value is
increased by 66.67% of previous sales load deductions and during the third
Policy year the cash value is increased by 33.33% of the previous sales load
deductions. This increase in cash value during the first three Policy years does
not apply if the Policy is in a grace period on the date on which you surrender
the Policy. This increase in cash value is not available in New Jersey. The cash
values shown in the illustrations on pages 42 - 49 are not correct for Policy
Years 1, 2 and 3 for Policies sold in New Jersey. Corrected illustrations are
available upon request.

We determine the cash value for a Policy 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,

                                       8


<PAGE>   14


we may also determine the cash value for a Policy on any other day on which
there is sufficient trading in securities to materially affect the value of the
securities held by the Portfolios or Funds.

For Policies issued prior to November 8, 1999, including Policies issued after
that date in states where the current Policy form has not been approved, 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. The 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 you surrender the Policy. This increase
in cash value is not available in New Jersey. See "Policies Issued Prior to
November 8, 1999", p. 8.

POLICY LOANS

You 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%. We add unpaid interest 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. We will send you a notice at least 61 days before the
termination date. The notice will show how much you must pay to keep the Policy
in force.

We will take the amount of a Policy loan from the Account divisions in
proportion to the amounts in the divisions. We will transfer the amounts
withdrawn to our general account and will credit them on a daily basis with an
annual earnings rate equal to the 5% Policy loan interest rate. A Policy loan,
even if you repay it, 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.

You may repay a Policy loan, and any accrued interest outstanding, in whole or
in part, at any time. We will credit payments as of the date we receive them and
will transfer those amounts from our general account 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. 11.

WITHDRAWALS OF POLICY VALUE

You 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. We permit up to four
withdrawals in a Policy year. An administrative charge of up to $25 may apply,
but we are currently waiving this charge.

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 we would
currently issue.

We will take the amount withdrawn from Policy Value from the Account divisions
in proportion to the amounts in the divisions. The Policy makes no provision for
repayment of amounts withdrawn. A withdrawal of Policy Value may have important
tax consequences. See "Tax Considerations", p. 11.

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, we allow a grace period of 61 days for the payment of sufficient premium
to keep the Policy in force. The grace period begins on the date that we send
you a notice. The notice will state the minimum amount of premium required to
keep the Policy in force and the date by which you must pay the premium. The
Policy will terminate unless you pay the required amount 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 our Home Office, subject
to our approval. 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

                                       9

<PAGE>   15



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. We will allocate
the Policy Value 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. 11, for a discussion of the tax effects associated
with termination and reinstatement of a Policy.

RIGHT TO RETURN POLICY

You may return a Policy within 45 days after you signed the application for
insurance or within 10 days (or later where required by state law) after you
receive the Policy, whichever is later. You may mail or deliver the Policy to
the agent who sold it or to our Home Office. If you return it, we will consider
the Policy void from the beginning. We will refund the sum of the amounts
deducted from the premium paid plus the value of the Policy in the Account on
the date we receive the returned Policy. In some states, the amount we refund
will not be less than the premium you 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. We must receive written proof of the transfer at our Home Office. "You"
in this prospectus means the owner or prospective purchaser of a Policy.

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

INCONTESTABILITY. We 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. We will not
contest an increase in the amount of insurance that was subject to insurability
requirements 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,
we will adjust the charges for cost of insurance and other expenses under a
Policy to reflect the correct age and sex.

COLLATERAL ASSIGNMENT. You may assign a Policy as collateral security. We are
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 our Home Office.

DEFERRAL OF DETERMINATION AND PAYMENT. We will ordinarily pay Policy benefits
within seven days after we receive all required documents at our Home Office.
However, we may defer determination and payment of benefits 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.

DIVIDENDS. The Policies will share in divisible surplus to the extent we
determine annually. Since we do not expect the Policies to contribute to
divisible surplus, we do not expect to pay any dividends.

VOTING RIGHTS

We are the owner of the shares of both mutual funds in which all assets of the
Account are invested. As the owner of the shares we will exercise our right to
vote the shares to elect directors of the mutual funds, 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 mutual fund shareholders' meeting. However, we will vote the
mutual fund shares held in the Account in accordance with instructions from
owners of the Policies. We will vote any shares of the mutual funds held in our
general account in the same proportions as the shares for which we have received
voting instructions. If the applicable laws or regulations change so as to
permit us to vote the shares in our own discretion, we may elect to do so.

The number of mutual 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 Value apportioned to that division, if any, by the per share value
for the corresponding Portfolio or Fund. The number will be determined as of a
date we choose, but not more than 90 days before the shareholders' meeting.
Fractional votes are counted. We will solicit voting instructions with written
materials at least 14 days before the meeting. We will vote shares as to which
we receive no instructions in the same proportion as the shares as to which we
receive instructions.

We may, if required by state insurance officials, disregard voting instructions
which would require mutual fund shares to be voted for a change in the
sub-classification or investment objectives of a Portfolio or Fund, or to
approve or disapprove an investment advisory agreement for either of the mutual
funds. We may also disregard voting instructions that

                                       10

<PAGE>   16


would require changes in the investment policy or investment adviser for either
a Portfolio or a Fund, provided that we reasonably determine to take this action
in accordance with applicable federal law. If we disregard voting instructions,
we will include a summary of the action and reasons therefor in the next
semiannual report to the owners of the Policies.

SUBSTITUTION OF FUND SHARES AND OTHER CHANGES

If, in our judgment, a Portfolio or Fund becomes unsuitable for continued use
with the Policies because of a change in investment objectives or restrictions,
shares of another Portfolio or Fund 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. We have 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 you will receive a statement showing the death
benefit, cash value, Policy Value and any Policy loan, including loan interest.
This report will show the apportionment of invested assets among the Account
divisions. You will also receive annual and semiannual reports for the Account
and both of the mutual funds, including financial statements.

DISTRIBUTION OF THE POLICIES


We sell the Policies through individuals who are licensed life insurance agents
appointed by Northwestern Mutual and are registered representatives of
Northwestern Mutual Investment Services, LLC ("NMIS"), our wholly-owned
subsidiary. 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 39-0509570.


Commissions paid to the agents will not exceed 15% of the premium for the first
year, 5.75% of the premium for years 2-6, and 2.75% 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 considerations 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. We do not intend this 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. 6. We have designed the Policy
to comply with these rules. We will return premiums that would cause a Policy to
be disqualified as life insurance, or take any other action that may be
necessary for the Policy to qualify as life insurance.


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. We intend
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. We believe that we own 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, a loan
received under a Policy will not be treated as a distribution subject to current
federal income tax. Interest paid by individual owners of the Policies will
ordinarily not be deductible. You should consult a qualified tax adviser as to
the deductibility of

                                       11

<PAGE>   17



interest paid, or accrued, by other purchasers of the Policies. See "Other Tax
Considerations", p. 13.


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. You
should seek qualified tax advice if you plan a transfer of ownership.

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.

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 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.

<PAGE>   18



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 on nonlife insurance indebtedness 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. There is also a risk that the accrued earnings in equity split dollar
policies may be taxable in the year earned. The Internal Revenue Service is
currently reviewing the taxation of split dollar arrangements generally and has
issued certain technical advice memoranda (which apply only to the taxpayer
under audit) which have disallowed an issuer's one-year term rates or imposed a
different taxation scheme on a particular taxpayer.


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. If you contemplate any such transaction you should consult a
qualified tax adviser.

Report of Independent Accountants

To the Northwestern Mutual Life Insurance Company and
Contract Owners 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 of changes in
equity present fairly, in all material respects, the financial position of
Northwestern Mutual Variable Life Account and the Small Cap Growth Stock
Division, Aggressive Growth Stock Division, International Equity Division, Index
400 Stock Division, Growth Stock Division, Growth & Income Stock Division, Index
500 Stock Division, Balanced Division, High Yield Bond Division, Select Bond
Division, Money Market Division, Russell Multi-Style Equity Division, Russell
Aggressive Equity Division, Russell Non-U.S. Division, Russell Real Estate
Securities Division and Russell Core Bond Division thereof at December 31, 1999,
the results of each of their operations for each of the two years or the period
then ended and the changes in each of their equity for the two years or the
period then ended in conformity with accounting principles generally accepted in
the United States. 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 auditing
standards generally accepted in the United States 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, 1999 with Northwestern Mutual Series Fund, Inc. and
the Russell Insurance Funds, provide a reasonable basis for the opinion
expressed above.

NORTHWESTERN MUTUAL VARIABLE LIFE ACCOUNT
Notes to Financial Statements
December 31, 1999

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") 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 and the
Russell Insurance Funds (collectively known as "the Funds"). The shares are
valued at the Funds' offering and redemption prices per share. The Funds are
diversified open-end investment companies registered under the Investment
Company Act of 1940.

NOTE 4 -- Dividend income from the Funds is recorded on the record date of the
dividends. Transactions in the Funds shares are accounted for on the trade date.
The basis for determining cost on sale of Funds shares is identified cost.
Purchases and sales of the Funds shares for the period ended December 31, 1999
by each Division are shown below:

NOTE 5 -- A deduction for mortality and expense risks is determined daily and
paid to Northwestern Mutual. Generally, for Variable Life policies issued before
October 11, 1995, and Variable Complife 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. A deduction for the mortality and expense risks for
the Variable Executive Life policies issued on or after March 3, 1998 is
determined monthly at an annual rate of .75% of the amount invested in the
Account for the Policy for the first ten Policy years, and .30% thereafter. 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, single or other premiums
before amounts 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 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 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. Policies
provide that a charge for taxes may be made against the assets of the Account.
Generally, for Variable Life policies issued before October 11, 1995,
Northwestern Mutual 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 Variable Complife policies
issued on or after October 11, 1995, and for Variable Executive Life policies
issued on or after March 3, 1998, there is no charge being made against the
assets of the Account for federal income taxes, but Northwestern Mutual 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
pay their premiums. Northwestern Mutual's equity represents any unpaid portion
of net annual premiums. This applies to Variable Life and Variable Complife
policies only.

THE NORTHWESTERN MUTUAL LIFE INSURANCE COMPANY
Notes to Consolidated Statutory Financial Statements
December 31, 1999, 1998 and 1997

NOTE 1 -- BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying consolidated statutory financial statements include the
accounts of The Northwestern Mutual Life Insurance Company ("Company") and its
wholly-owned subsidiary, Northwestern Long Term Care Insurance Company
("Subsidiary"). The Company and its Subsidiary offer life, annuity, disability
income and long-term care 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").

In 1998, the National Association of Insurance Commissioners ("NAIC") adopted
the Codification of Statutory Accounting Principles ("Codification") guidance,
which will replace the current Accounting Practices and Procedures manual as the
NAIC's primary guidance on statutory accounting. The NAIC is now considering
amendments to Codification that would also be effective upon implementation.
Codification provides guidance for areas where statutory accounting has been
silent and changes current statutory accounting in some areas (e.g., deferred
income taxes are recorded). The Office of the Commissioner of Insurance of the
State of Wisconsin ("OCI") intends to adopt Codification effective January 1,
2001. The Company has not determined the potential effect of Codification, and
the eventual effect of adoption could differ if changes are made prior to the
effective date of January 1, 2001.

Financial statements prepared on the statutory basis of accounting vary from
financial statements prepared on the basis of generally accepted accounting
principles ("GAAP") 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:

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 fair value,
preferred stocks are generally carried at cost, and unconsolidated subsidiaries
are recorded using the equity method

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 venture investments which are
valued at equity in ventures' net assets

Cash and temporary investments -- Amortized cost, which approximates fair value

TEMPORARY INVESTMENTS

Temporary investments consist of debt securities that have maturities of one
year or less at acquisition.

NET INVESTMENT INCOME AND CAPITAL GAINS

Net investment income includes interest and dividends received or due and
accrued on investments, equity in unconsolidated subsidiaries' earnings and the
Company's share of joint venture income. Net investment income is reduced by
investment management expenses, real estate depreciation, depletion related to
energy assets and costs associated with securities lending.

Realized investment gains and losses are reported in income based upon specific
identification of securities sold. Unrealized investment gains and losses
include changes in the fair

                                       33

value of common stocks and changes in valuation allowances made for bonds,
preferred stocks, mortgage loans and other investments considered by management
to be impaired.

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.

INVESTMENT RESERVES

The Company is required to maintain an asset valuation reserve ("AVR"). The AVR
establishes a general reserve for invested asset valuation using a formula
prescribed by state regulations. The AVR is designed to stabilize surplus
against potential declines in the value of investments. In addition, the Company
maintained a $200 million voluntary investment reserve at each of December 31,
1999 and 1998 to absorb potential investment losses exceeding those considered
by the AVR formula. Increases or decreases in these investment reserves are
recorded directly to surplus.

SEPARATE ACCOUNTS

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. Variable product
policyowners also have the option to invest in a fixed interest rate annuity in
the general account of the Company. Separate account assets are reported at fair
value.

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.

OTHER INCOME

Other income includes considerations on supplementary contracts, ceded
reinsurance expense allowances and miscellaneous policy charges.

BENEFIT PAYMENTS TO POLICYOWNERS AND BENEFICIARIES

Benefit payments to policyowners and beneficiaries include death, surrender and
disability benefits, matured endowments and supplementary contract payments.

RESERVES FOR POLICY BENEFITS

Reserves for policy benefits are determined using actuarial estimates based on
mortality and morbidity experience tables and valuation interest rates
prescribed by the OCI. (See Note 3.)

POLICYOWNER DIVIDENDS

Almost all life insurance policies, and certain annuity and disability income
policies issued by the Company are participating. Annually, the Company's Board
of Trustees approves dividends payable on participating policies in the
following fiscal year, which are accrued and charged to operations when
approved.

RECLASSIFICATION

Certain financial statement balances for 1998 and 1997 have been reclassified to
conform to the current year presentation.

DEBT SECURITIES

Debt securities consist of all bonds and fixed-maturity preferred stocks. The
estimated fair values of debt securities 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.
Statement value, which principally represents amortized cost, and estimated fair
value of the Company's debt securities at December 31, 1999 and 1998 were as
follows:

STOCKS

The estimated fair 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 adjusted cost of common and preferred stock held by the Company at December
31, 1999 and 1998 was $4.9 billion and $4.3 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 collateral
properties.

The fair value of mortgage loans as of December 31, 1999 and 1998 was $13.2
billion and $12.9 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, 1999 and 1998, real estate includes $39 million and $61 million,
respectively, acquired through foreclosure and $114 million and $120 million,
respectively, of home office real estate.

SECURITIES LENDING

The Company has entered into securities lending agreements whereby certain
securities are loaned to third parties, primarily major brokerage firms. The
Company's policy requires a minimum of 102% 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 $2.1 billion and $1.5 billion, respectively, are included in
the consolidated statements of financial position at December 31, 1999 and 1998,
and approximate the statement value of securities loaned at those dates.

INVESTMENT IN MGIC

The Company owns 11.3% (11.9 million shares) of the outstanding common stock of
MGIC Investment Corporation ("MGIC"). This investment is accounted for using the
equity method. At December 31, 1999 and 1998, the fair value of the Company's
investment in MGIC exceeded the statement value of $201 million and $180
million, respectively, by $518 million and $296 million, respectively.

In August 1998, the Company delivered 8.9 million shares of MGIC to a brokerage
firm to settle a forward contract. In conjunction with the settlement, the
Company recorded a $114 million realized gain.

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.

</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.

In addition to the use of derivatives for hedging purposes, equity swaps were
held for investment purposes during 1999 and 1998. The notional amount of equity
swaps outstanding at December 31, 1999 and 1998 was $136 million and $138
million, respectively.

Foreign currency forwards, foreign currency swaps, stock futures and equity
swaps are reported at fair value. Resulting gains and losses on these contracts
are unrealized until expiration of the contract. There is no statement value
reported for interest rate swaps, bond futures and options to acquire interest
rate swaps prior to the settlement of the contract, at which time realized gains
and losses are deferred to IMR. Changes in the value of derivative instruments
are expected to offset gains and losses on the hedged investments. During 1999
and 1998, net realized and unrealized gains on investments were partially offset
by net realized losses of $55 million and $104 million, respectively, and net
unrealized gains (losses) of $17 million and $(58) million, respectively, on
derivative instruments. The effect of derivative instruments in 1997 was not
material to the Company's results of operations.

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 with interest rates ranging
from 3 1/2% to 5 1/2%. Other life policy reserves are primarily based 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 primarily
using the Commissioner's Annuity Reserve Valuation Method with interest rates
ranging from 3 1/2% to 6 1/4%. Other deferred annuity reserves are based on
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%.

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 based on 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 primarily using the 1985 CIDA
(modified for Company experience in the first four 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. 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 are funded. As of
                            Notes to Consolidated Statutory Financial Statements
                                       37
<PAGE>   43

January 1, 1999, the most recent actuarial valuation date available, the
qualified defined benefit plans were fully funded. The Company recorded a
liability of $109 million and $98 million for nonqualified defined benefit plans
at December 31, 1999 and 1998, respectively. 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 plans. The Company recorded
$31 million, $29 million and $27 million of total expense related to its defined
benefit and defined contribution plans for the years ended December 31, 1999,
1998 and 1997, respectively. The defined benefit and defined contribution plans'
assets of $2.2 billion and $1.9 billion at December 31, 1999 and 1998,
respectively, were primarily invested in the separate accounts of the Company.

In addition to pension and retirement 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
costs for the years ended December 31, 1999, 1998 and 1997 were a net expense
(benefit) of $5.0 million, $1.8 million and ($1.3) million, respectively.

</TABLE>

If the health care cost trend rate assumptions were increased by 1%, the accrued
postretirement benefit obligation as of December 31, 1999 and 1998 would have
been increased by $6 million and $5 million, respectively.

At December 31, 1999 and 1998, the recorded postretirement benefit obligation
was reduced by $28 million and $23 million, respectively, for health care
benefit plan assets. These assets were primarily invested in the separate
accounts of the Company.

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 coinsurance contracts. The Company
retains a maximum of $25 million of coverage per individual life and $35 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. Reserves for policy benefits at December 31, 1999 and 1998 were
reported net of ceded reserves of $584 million and $518 million, respectively.
The effect of reinsurance on premiums and benefits for the years ended December
31, 1999, 1998 and 1997 was as follows:

                               ======   ======   ======
</TABLE>

In addition, the Company received $133 million, $121 million and $115 million
for the years ended December 31, 1999, 1998 and 1997, respectively, from
reinsurers representing allowances for 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
policyowners. 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

Notes to Consolidated Statutory Financial Statements
                                       38
<PAGE>   44

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 1995 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 taxable income can vary significantly from gain from operations
before taxes due to differences between book and tax valuation of assets and
liabilities (e.g., investments and policy benefit reserves). The Company pays a
tax that is assessed only on the surplus of mutual life insurance companies
("equity tax"), and also, the Company must capitalize and amortize, as opposed
to immediately deducting, an amount deemed to represent the cost of acquiring
new business ("DAC tax").

The Company's effective tax rate on gains from operations before taxes for the
years ended December 31, 1999, 1998 and 1997 was 29%, 48%, and 56% respectively.
In 1999, the effective rate was less than the federal corporate rate of 35% due
primarily to differences between book and tax investment income. In 1998 and
1997, the effective rate was greater than 35% due primarily to the equity tax
and DAC tax.

NOTE 7 -- RELATED PARTY TRANSACTIONS

The Company acquired Frank Russell Company ("Frank Russell") effective January
1, 1999 for a purchase price of approximately $950 million. Frank Russell is a
leading investment management and consulting firm, providing investment advice,
analytical tools and investment vehicles to institutional and individual
investors in more than 30 countries. This investment is accounted for using the
equity method and is included in common stocks in the consolidated statement of
financial position. In 1999, the Company charged-off directly from surplus
approximately $842 million, representing the total goodwill associated with the
acquisition. The Company has received permission from the OCI for this
charge-off. The Company has unconditionally guaranteed certain debt obligations
of Frank Russell, including $350 million of senior notes and up to $150 million
of other credit facilities.

During 1999, the Company transferred appreciated equity investments to a
wholly-owned subsidiary as a capital contribution to the subsidiary. A realized
capital gain of $287 million was recorded on this transaction based on the fair
value of the assets upon transfer.

NOTE 8 -- CONTINGENCIES

The Company has guaranteed certain obligations of its other affiliates. These
guarantees totaled approximately $101 million at December 31, 1999 and are
generally supported by the underlying net asset values of the affiliates.

In addition, the Company routinely makes commitments to fund mortgage loans or
other investments in the normal course of business. These commitments aggregated
to $1.9 billion at December 31, 1999 and were extended at market interest rates
and terms.

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 position.

R EPORT 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, 1999 and 1998, and the related consolidated statements of operations, of
changes in surplus and of cash flows for each of the three years in the period
ended December 31, 1999. 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 auditing standards generally accepted
in the United States. 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.

As described in Note 1 to the financial statements, the Company prepared these
consolidated financial statements using 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
accounting principles generally accepted in the United States. 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 as of December 31, 1999 and 1998, or the results of their operations
or their cash flows for each of the three years in the period ended December 31,
1999 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 as of December 31, 1999 and 1998 and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1999, 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. These illustrations, on pages 42 - 45, 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 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 Portfolio or Funds return rate averaged 0%, 6% or 12%, but the
rates for each individual Portfolio or Fund 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 three years. The amounts shown also
reflect the average of the investment advisory fees and other expenses
applicable to each of the Portfolios and Funds at the annual rate of .66% of
their net assets. See "The Funds", p. 4. Thus the 0%, 6% and 12% gross
hypothetical return rates on the Fund's assets are equivalent to the net rates
of -.66%, 5.34% and 11.34% 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 42 and 44
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.

IT IS EMPHASIZED THAT THE HYPOTHETICAL INVESTMENT RESULTS ARE ILLUSTRATIVE ONLY
AND SHOULD NOT BE DEEMED A REPRESENTATION OF PAST OR FUTURE INVESTMENT RESULTS.
ACTUAL INVESTMENT RESULTS MAY BE MORE OR LESS THAN THOSE SHOWN AND WILL DEPEND
UPON A NUMBER OF FACTORS, INCLUDING THE INVESTMENT ALLOCATIONS MADE BY AN OWNER
TO THE DIVISIONS OF THE VARIABLE ACCOUNT AND THE DIFFERENT RATES OF RETURN OF
THE VARIABLE ACCOUNT.

THE DEATH BENEFIT AND CASH VALUE FOR A POLICY WOULD BE DIFFERENT FROM THOSE
SHOWN IF THE ACTUAL INVESTMENT RATES OF RETURN AVERAGED 0%, 6% AND 12% OVER A
PERIOD OF YEARS, BUT FLUCTUATED ABOVE OR BELOW THOSE AVERAGES FOR INDIVIDUAL
POLICY YEARS. THEY WOULD ALSO BE DIFFERENT IF PREMIUMS WERE PAID IN DIFFERENT
AMOUNTS OR FREQUENCIES THAN SHOWN. NO REPRESENTATIONS CAN BE MADE THAT THESE
HYPOTHETICAL RATES OF RETURN CAN BE ACHIEVED FOR ANY ONE YEAR OR SUSTAINED OVER
A PERIOD OF TIME.

THE CASH VALUES SHOWN IN THIS ILLUSTRATION FOR POLICY YEARS 1, 2, AND 3 ARE NOT
CORRECT FOR POLICIES SOLD IN NEW JERSEY. SEE "CASH VALUE", p. 8. A CORRECTED
ILLUSTRATION IS AVAILABLE UPON REQUEST.

                                  Exhibit C(6)


                                                              April 25, 2000

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

Gentlemen:

     This opinion is furnished in connection with Post-Effective Amendment No. 4
to the Registration Statement on Form S-6, Registration No. 333-36865, of
Northwestern Mutual Variable Life Account. The prospectus included in
Post-Effective Amendment No. 4 ("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 42
     through 49 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 8 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
