         This prospectus describes the VariTrak policy, a variable universal
life insurance policy offered by National Life Insurance Company. This Policy
combines insurance and investment features. The policy's primary purpose is to
provide insurance protection on the life of the insured person. You can make
premium payments at various times and in various amounts. You can also allocate
premiums among a number of funds with different investment objectives, and you
can increase or decrease the death benefit payable under your policy.

         We deduct certain charges from premium payments. Then these premium
payments go to the National Variable Life Insurance Account, a separate account
of National Life, or to the general account, or a combination of the two. The
general account pays interest at rates guaranteed to be at least 4%. The
separate account has twenty-six subaccounts. Each subaccount buys shares of a
specific fund portfolio. The available funds are:

The value of your policy will depend upon the investment results of the funds
you select. You bear the entire investment risk for all amounts allocated to the
separate account; there is no guaranteed minimum value for any of the funds, and
the value of your policy may be more or less than premiums paid.

You must receive, with this prospectus, current prospectuses for all of the fund
options. They describe the investment objectives and the risks of the funds.

The value of your policy will also reflect our charges. These include a premium
tax charge, cost of insurance charges, a mortality and expense risk charge, an
administrative charge, and certain other charges. During the first five years
your policy will remain in force if specified premiums are paid on time, or if
the policy has enough value to pay the monthly charges as they become due. After
the fifth year, the Policy will remain in force only so long as it has enough
value to pay the monthly charges as they become due.

We recommend that you read this prospectus carefully. You should keep it to
refer to later.

Investments in these contracts are not deposits or obligations of, and are not
guaranteed or endorsed by, adviser of any of the underlying funds identified
above, the U.S. government, or any bank or bank affiliate. Investments are not
federally insured by the Federal Deposit Insurance Corporation, the Federal
Reserve Board, or any other governmental agency.

    It may not be advantageous to purchase a policy as a replacement for another
    type of life insurance or as a means to obtain additional insurance
    protection if you already own another variable universal life insurance
    policy.

    THE SECURITIES AND EXCHANGE COMMISSION HAS NOT APPROVED OR DISAPPROVED THE
    POLICY OR DETERMINED IF THIS PROSPECTUS IS ACCURATE OR COMPLETE. ANY
    REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                        SUMMARY DESCRIPTION OF THE POLICY

      You should read this summary of the policy provisions together with the
detailed information appearing later in this Prospectus. Unless otherwise noted,
this Prospectus assumes the insured person is alive. The precise meanings of the
few capitalized terms used in this summary can be found in the Glossary, on
pages to .

THE POLICY

      National Life Insurance Company issues the VariTrak variable universal
life insurance policy. This life insurance policy allows you, within limits, to
make premium payments in any amount and whenever you like. As long as the policy
remains in force, it will provide for:

         (1) Life insurance coverage which will provide a death benefit on the
             death of the named insured person;

         (2) A cash surrender value;

         (3) Surrender and withdrawal rights and policy loan privileges; and

   
         (4) A variety of additional insurance benefits (where provided by 
             optional riders, so long as those riders remain in force). 
    

         This policy is designed to help lessen the economic loss resulting from
the death of the insured person. You should consider your need for insurance
coverage and the policy's investment potential on a long-term basis.

   
         There is no fixed schedule for premium payments, although you may
establish a schedule of planned periodic premiums. You may also, after a year
and within limits, increase or decrease the policy's face amount, and you may
change the death benefit option. The policy's value and death benefit will
fluctuate based on the investment results of the chosen fund portfolios, the
crediting of interest to the general account, and the deduction of charges.
    

         Lapse. The policy will not lapse simply because you do not pay any
particular amounts of premiums. However, the payment of premiums in any amount
or frequency will not necessarily guarantee that the policy will remain in
force. In general, the policy will lapse if it does not have enough value to pay
the monthly charges as they become due. During the first five years, the policy
will not lapse even if its value is not enough to pay the monthly charges, if at
least specified amounts of premiums have been paid (these amounts are defined in
the Glossary as the Minimum Guarantee Premium). See "How the Duration of the
Policy May Vary," page .

   
        Optional Guaranteed Death Benefit Rider. In addition, if you buy the
optional Guaranteed Death Benefit Rider, your policy will not lapse even if its
value is not enough to pay the monthly charges, if you have paid at least the
Minimum Guarantee Premium, until the later of 20 years from the date the policy
is issued or the insured person attains age 70. See "Optional Benefits -
Guaranteed Death Benefit Rider," page .
    

                                       3
<PAGE>   7
         If you already have life insurance, you should consider whether or not
changing or adding to existing coverage would be advantageous. It may not be
advisable to purchase another policy as a replacement for an existing policy.

THE SEPARATE ACCOUNT

         The separate account is divided into subaccounts, 26 of which are
available under this policy. Each of these subaccounts buys shares of a
corresponding fund portfolio. See "National Life Insurance Company, the Separate
Account, and the Funds," page .

         We cannot give any assurance that any portfolio will achieve its
investment objectives. You bear the entire investment risk on the value of your
policy which you allocate to the separate account.

AVAILABILITY OF POLICY

         We will issue this policy for insured persons from ages 0 to 85. The
minimum face amount is generally $50,000, although exceptions to this minimum
may be made for employee benefit plans. Before issuing a policy, we will require
that the proposed insured person meet certain underwriting standards. We will
assign the insured person to one of the following types of rate classes:

   
     -   Preferred Nonsmoker
     -   Standard Nonsmoker
     -   Smoker
     -   Juvenile, or
     -   Substandard.
    

See "Issuance of a Policy," Page .

THE DEATH BENEFIT

   
         As long as your policy remains in force, we will pay the death benefit
to your beneficiary, when we receive due proof of the death of the insured
person. The death benefit will be increased by any additional benefits provided
by a supplementary benefit rider. The death benefit will be reduced by any
outstanding policy loans and accrued interest, and any unpaid monthly
deductions.
    

         There are two death benefit options available, which we call Option A
and Option B. You may choose which option will apply to your policy.

      If you choose death benefit Option A, the death benefit will be based on
the greater of :

         (a) the face amount, or

         (b) the Accumulated Value multiplied by a factor specified by federal
             income tax law.

         If you choose death benefit Option B, the death benefit will be based
on the greater of:

         (a) the face amount plus the Accumulated Value, or

         (b) the Accumulated Value multiplied by the same factor that applies to
             option A.

                                       4
<PAGE>   8
See "Death Benefit Options," Page ___.

FLEXIBILITY TO ADJUST AMOUNT OF DEATH BENEFIT

         After a year, you may adjust the death benefit by changing the death
benefit option or by increasing or decreasing the face amount of your policy.
(See "Change in Death Benefit Option," Page ___, and "Ability to Adjust Face
Amount," Page ___.)

         Any change in death benefit option or in the face amount may affect the
charges under your policy. If you increase the face amount, your monthly charges
will increase. A decrease in face amount may decrease the monthly charges. (See
"Cost of Insurance Charge," Page ___.)

         If you request a decrease in face amount which would cause the policy
not to qualify as life insurance under federal tax law, we will not allow the
decrease.

ACCUMULATED VALUE

         The Accumulated Value is the total amount of value held in the policy
at any time. It equals the sum of the amounts held in the separate account and
the general account. (See "Calculation of Accumulated Value," Page .)

         The Accumulated Value in the separate account will reflect:

   
     -   the investment performance of your chosen funds
     -   premiums paid
     -   transfers
     -   withdrawals
     -   policy loans
     -   loan repayments
     -   loan interest charged, and
     -   the charges assessed in connection with the policy.
    

         We pay interest on Accumulated Value in the general account at rates we
declare in advance for specific periods. We guarantee that these rates will be
at least 4%. (See "The General Account," Page ___.)

   
         The Accumulated Value will likely impact both the death benefit and the
cost of insurance charges.
    

ALLOCATION OF PREMIUMS

         You will specify, in the application for your policy, the percentages
of premium to go to each subaccount of the separate account or to the general
account. You may change these percentages whenever you like. You may choose
among all 26 available subaccounts of the separate account. However, we may
limit the number of different subaccounts, other than the money market
subaccount, used in your policy over its entire life to 16.

   
         We will allocate all premiums, after reduction for premium taxes,
received during the free-look period that are to go to the separate account to
the money market subaccount. At the end of the free look period, we will move
the amount in the money market subaccount (including investment experience) to
your chosen subaccounts. For this purpose,
    


                                       5
<PAGE>   9

   
we will assume that the free-look period ends 20 days after the date the policy
is issued. Premiums received after the free look period ends will be allocated
directly to your chosen subaccounts.  (See "Allocation of Net Premiums," Page
___.)
    

TRANSFERS

         You may transfer the amounts in the subaccounts and the general
account. Transfers between the subaccounts or from the separate account into the
general account will be made on the day we receive the request. We limit
transfers out of the general account to the greater of $1000 and 25% of the
Accumulated Value in the general account. We also allow only one transfer out of
the general account per year. See "Transfers," page .

FREE-LOOK PRIVILEGE

   
         The Policy provides for an initial "free-look" period, during which you
may cancel the Policy and receive a refund equal to the premiums you paid. This
free-look period ends on the latest of:
    

(a) 45 days after you sign Part A of your application for the Policy 
(b) 10 days after you receive the Policy, and 
(c) 10 days after we mail or personally deliver to you a Notice of
    Withdrawal Right,

or, in each case, any longer period provided by state law. To cancel your
policy, you must return the Policy to us or to our agent within such time with a
written request for cancellation. (See "Free-Look Privilege," Page .)

         We expect these reimbursement arrangements to continue, but there are
no legal obligations to continue these arrangements for any particular period of
time; if they are terminated, the affected Portfolios' expenses may increase.

         Premium Tax Charge. We deduct a premium tax charge from each premium
payment, to cover the cost of state and local premium taxes, and the federal DAC
tax. This charge is 3.25% of each premium. For qualified employee benefit plans,
the charge will be 2.00% of each premium rather than 3.25%. We may change the
amount of the charge deducted from future premiums if the applicable law
changes. (See "Premium Tax Charge," Page .)

         Monthly Deductions. On the date of issue and each month thereafter, we
will take a deduction from the Accumulated Value equal to the sum of:

         (a) the monthly cost of insurance charge

         (b) the monthly administrative charge, and

         (c) if applicable, a charge for any additional benefits added by rider.
   
         We calculate the monthly cost of insurance charge by multiplying the
net amount at risk (that is, the unadjusted death benefit less the policy's
Accumulated Value) by the applicable cost of insurance rate(s). These rates will
depend upon the age, sex, and rate class of the insured person, the time the
coverage has been in force, your policy size, and on our expectations of future
mortality and expense experience. Our cost of insurance rates cannot exceed the
guaranteed maximum cost of insurance rates set forth in your policy. These
guaranteed maximum rates are based on the insured person's age, sex, rate class,
and the "1980 Commissioners Standard Ordinary Smoker and Nonsmoker Mortality
Table." (See "Cost of Insurance Charge," Page .)
    
   
         The monthly administrative charge is $7.50. (See "Monthly
Administrative Charge," Page .) 
    
   
         After 10 years, we currently intend to apply a bonus under which the 
Monthly Deductions will be reduced by 0.50% per annum of the Accumulated Value
in the separate account. (See "Bonus," Page .) However, we do not guarantee such
a bonus, except as required by the state of issue.
    
         Surrender Charge. We impose a surrender charge if you surrender your
policy or it lapses at any time during the first 15 years. The surrender charge

                                       8
<PAGE>   12
consists of a deferred administrative charge and a deferred sales charge. (See
"Surrender Charge," Page .)

         The deferred administrative charge is generally initially $2 per
$1,000 of initial face amount (lower for insured people under 25 years old at
issue). After the first five years, the deferred administrative charge declines
linearly by month until the end of the fifteenth year, when it becomes zero.

         We calculate the deferred sales charge individually for each policy,
based on its surrender charge target premium. The surrender charge target
premium is based on the initial face amount, and the age, sex and rate class of
the insured person. It is used solely for the purpose of calculating the
deferred sales charge. Your surrender charge target premium will be shown in
your Policy.

         The deferred sales charge is equal to the lesser of:

         (a)      30% of the premiums received up to one surrender charge target
                  premium, plus 10% of all premiums paid in excess of this
                  amount but not greater than twice this amount, plus 9% of all
                  premiums paid in excess of twice this amount,

                   or

   
          (b)  the maximum deferred sales charge, which is based on the initial
               face amount, and the age, sex and rate class of the insured
               person. The maximum deferred sales charge, which will be shown in
               your policy, is level for the first five years, and then declines
               linearly by month through the end of the fifteenth year, when it
               becomes zero.

     Appendix B to this Prospectus contains a table showing the surrender charge
target premium and the maximum deferred sales charge for male and female
nonsmokers and smokers of each age at the time a policy is issued, expressed as
a dollar amount per $1000 of initial face amount.
    

      Daily Charge Against the Separate Account (Mortality and Expense Risk
Charge). We assess a daily charge for assuming certain mortality and expense
risks incurred in connection with the policies. This charge is currently 0.90%
annually of the average daily net assets of the separate account. (See
"Mortality and Expense Risk Charge," Page .)

         Withdrawal Charge. If you make a withdrawal from your policy, we assess
a withdrawal charge equal to the lesser of 2% of the amount withdrawn or $25.
(See "Withdrawal Charge," Page .)

      Transfer Charge. You may transfer value among the subaccounts on any
business day, without charge. We have no current intent to impose a transfer
charge in the foreseeable future; however, we may impose in the future a charge
of $25 for each transfer in excess of five transfers in any one year. (See
"Transfer Charge," Page ___.)

                                       9
<PAGE>   13
         Projection Report Charge. If you request a projection report, we may
impose a charge. (See "Projection Report Charge," Page __.)

      Other Charges. Shares of the Portfolios are purchased by the subaccounts
at net asset value, which reflects management fees and expenses deducted from
the assets of the Portfolios. These management fees and expenses are shown above
under "Annual Charges of Underlying Funds".

LOAN PRIVILEGE

   
         After a year, you may borrow against your policy. The maximum amount of
all loans is the Cash Surrender Value less three times the most recent next
monthly deduction. Policy loans may be taken, or repayments made, on any
business day.
    

         We charge interest on Policy loans at a fixed rate of 6% per year.
Interest is added to the loan balance at the end of each policy year. You may
repay policy loans at any time and in any amount. When the death benefit becomes
payable or the policy is surrendered, we will deduct policy loans and accrued
interest from the proceeds otherwise payable. When you take a policy loan, we
will hold Accumulated Value in the general account as collateral for the policy
loan. We credit interest on amounts held in the general account as collateral
for policy loans at rates we declare prior to each calendar year. This rate will
be at least 4%.

   
         We currently plan to credit interest on Accumulated Value held as
collateral for loans in the general account for policies that are more than 10
years old at rates which are 0.50% per annum higher than those that apply to
policies still in their first ten years. This bonus is not guaranteed, however,
except as required by the state of issue. We may decide, in our sole discretion,
upon prior notice to policy owners, not to credit the bonus. We also currently
plan to make preferred loans available when the insured person is 65 years old
or a policy is 20 years old, whichever is later. These preferred loans will be
limited in amount. For these preferred policy loans, we will credit interest on
the amount held in the general account as collateral at an annual rate of 6%.
However, we are not obligated to continue to make preferred loans available, and
we will make these loans available in our sole discretion. (See "Loan
Privileges," Page ___.)
    

         Loans may cause a policy to lapse, depending on investment performance
and the amount of the loan. If a policy is not a Modified Endowment Contract,
lapse with policy loans outstanding may result in adverse tax consequences. (See
"Tax Treatment of Policy Benefits," Page ___.)

                                       10
<PAGE>   14
WITHDRAWAL OF CASH SURRENDER VALUE

   
         After a year, you may request a withdrawal of Cash Surrender Value.
Withdrawals must be at least $500 (except that we may permit smaller withdrawals
for employee benefit plans). Withdrawals cannot be more than the Cash Surrender
Value minus three times the most recent monthly deduction. We will take the
withdrawal amount from the subaccounts based on your instructions. If you do not
provide instructions, we will take the withdrawal from the subaccount in
proportion to the values in the subaccounts. If the values in the subaccounts
will not allow us to carry out your instructions, we will not process the
withdrawal until you provide further instructions. You may not allocate
withdrawals to the general account until all the value in the separate account
has been exhausted. (See "Withdrawal of Cash Surrender Value," Page ___.)
    

SURRENDER OF THE POLICY

         You may surrender your policy at any time and receive the cash
surrender value, if any. The cash surrender value will equal the Accumulated
Value less any policy loan with accrued interest and any surrender charge. (See
"Surrender Privilege," Page ___.)

         Life insurance contracts receive tax-favored treatment under current
federal income tax law. Assuming that your policy qualifies as a life insurance
contract for federal income tax purposes, you should not be taxed on any
increase in cash surrender value while your policy remains in force. Also, your
beneficiary generally should not be taxed on death benefit proceeds. We believe
that a policy issued on a standard rate class basis generally should meet the
Section 7702 definition of a life insurance contract. For policies issued on a
substandard basis, there is insufficient guidance to determine if such a policy
would in all situations satisfy the Section 7702 definition of a life insurance
contract, particularly if you pay the full amount of premiums permitted under
the policy. (See "Tax Status of the Policy," Page ___.)

         A policy may be treated as a "Modified Endowment Contract" in some
situations. If your policy is a Modified Endowment Contract, then certain
pre-death distributions, including policy loans, will be treated first as a
distribution of taxable income and then as a return of basis or investment in
the contract. In addition, prior to age 59-1/2 any such distributions generally
will be subject to a 10% penalty tax. (For further discussion on the
circumstances under which a Policy will be treated as a Modified Endowment
Contract, See "Tax Treatment of Policy Benefits," Page ___.)

         If your policy is not a Modified Endowment Contract, distributions
generally will be treated first as a return of basis or investment in the
contract, and then as disbursing taxable income. Loans will not be treated as
distributions. Neither distributions nor loans from a policy that is not a
Modified Endowment

                                       11

Contract are subject to the 10% penalty tax. (See "Distributions from Policies
Not Classified as Modified Endowment Contracts," Page ___.)

OTHER POLICIES

      We offer other variable life insurance policies which also invest in the
same portfolios of the funds. These policies may have different charges that
could affect the value of the subaccounts and may offer different benefits more
suitable to your needs. To obtain more information about these policies, you may
write or call us at National Life Drive, Montpelier, Vermont 05604, (800)
537-7003.

ILLUSTRATIONS

         Illustrations of how investment performance of the subaccounts may
cause the death benefit, the Accumulated Value and the cash surrender value to
vary are included in Appendix A commencing on Page A-1.

         These illustrations of hypothetical values may help you understand the
long-term effects of different levels of investment performance, of charges and
deductions, and of electing one or the other death benefit option. They may also
be useful in generally comparing and contrasting this policy to other life
insurance policies. Nonetheless, the illustrations are based on hypothetical
investment rates of return. THEY ARE NOT GUARANTEED. Illustrations are not a
representation of past or future performance. Actual rates of return may be more
or less than those reflected in the illustrations and, therefore, actual values
will differ from those illustrated.

QUESTIONS

      If you have questions, you may write or call us at National Life Drive,

      NATIONAL LIFE INSURANCE COMPANY, THE SEPARATE ACCOUNT, AND THE FUNDS

NATIONAL LIFE INSURANCE COMPANY

   
         National Life Insurance Company ("National Life", or "we") is
authorized to transact life insurance and annuity business in Vermont and in 50
other jurisdictions. National Life was originally chartered as a mutual life
insurance company in 1848 under Vermont law. It is now a stock life insurance
company. All of its outstanding stock is indirectly owned by National Life
Holding Company, a mutual insurance holding company established under Vermont
law on January 1, 1999. All policyholders of National Life, including all the
Owners of the Contracts, are voting members of National Life Holding Company.
National Life assumes all insurance risks under the Policy and its assets
support the Policy's benefits. On December 31, 1998, National Life's
consolidated assets were over $9 billion. (See "Financial Statements," Page
F-1.)
    

THE SEPARATE ACCOUNT

         We established the Separate Account on February 1, 1985 under Vermont
law. It is a separate investment account to which we allocate assets to support
the benefits payable under the policies, other policies we currently issue, and
other variable life insurance policies we may issue in the future.

         The Separate Account's assets are the property of National Life. The
portion of the Separate Account's assets equal to the reserves and other
liabilities under the Policies (and other policies) supported by the Separate
Account will not be exposed to liabilities arising out of any other business
that we may conduct. The portion of the Separate Account's assets equal to the
reserves and other liabilities under the Policies may, however, be exposed to
liabilities arising from other subaccounts of the Separate Account that fund
other variable life insurance policies. The Separate Account may also include
amounts derived from expenses we have charged to the Policies (and other
policies) which we currently hold in the Separate Account, and amounts held to
support other variable life insurance policies we may issue. From time to time
we may move these additional amounts to our General Account.

         The Separate Account is registered with the Securities and Exchange
Commission ("SEC") under the Investment Company Act of 1940 ("1940 Act") as a
unit investment trust type of investment company. Such registration does not
involve any supervision of the management or investment practices or policies of
the Separate Account by the SEC. The Separate Account meets the definition of a
"separate account" under Federal securities laws.

         You may choose among the Subaccount options described below. However,
we may limit the number of different Subaccounts, other than the Money Market
Subaccount, used in any one Policy over its entire life to 16.

THE MARKET STREET FUND

         The Growth, Sentinel Growth, Aggressive Growth, Bond, Managed,
International, and Money Market Subaccounts of the Separate Account invest in
shares of The Market Street Fund, Inc., a "series" type of mutual fund which is
registered with the SEC under the 1940 Act as a diversified open-end management
investment company. Each series of Market Street Fund shares represents an
interest in a separate portfolio within the Fund. They are purchased and
redeemed by the corresponding Subaccounts of the Separate Account. The Market
Street Fund sells and redeems its shares at net asset value without a sales
charge.

         The investment objectives of the Market Street Fund's Portfolios you
may choose for your Policy are set forth below. The investment experience of
each of the Subaccounts of the Separate Account

                                       13
<PAGE>   17
depends on the investment performance of the corresponding Portfolio. There is
no assurance that any Portfolio will achieve its stated objective.

         The Growth Portfolio. The Growth Portfolio seeks intermediate and
long-term growth of capital. A reasonable level of income is an important
secondary objective. This Portfolio pursues its objectives by investing
primarily in common stocks of companies believed to offer above-average growth
potential over both the intermediate and the long term.

         The Sentinel Growth Portfolio. The Sentinel Growth Portfolio seeks
long-term growth of capital through equity participation in companies having
growth potential believed by its investment adviser to be more favorable than
the U.S. economy as a whole, with a focus on relatively well-established
companies.

         The Aggressive Growth Portfolio. The Aggressive Growth Portfolio seeks
to achieve a high level of long-term capital appreciation by investing in
securities of a diverse group of smaller emerging companies.

         The Bond Portfolio. The Bond Portfolio seeks to generate a high level
of current income consistent with prudent investment risk by investing in a
diversified portfolio of marketable debt securities.

         The Managed Portfolio. The Managed Portfolio seeks to realize as high a
level of long-term total rate of return as is consistent with prudent investment
risk by investing in stocks, bonds, money market instruments or a combination
thereof.

         The International Portfolio. The International Portfolio seeks
long-term growth of capital principally through investments in a diversified
portfolio of marketable equity securities of established non-United States
companies.

         The Money Market Portfolio. The Money Market Portfolio seeks to provide
maximum current income consistent with capital preservation and liquidity by
investing in high-quality money market instruments.

        Sentinel Advisors Company ("SAC") manages the Growth, Sentinel Growth,
Aggressive Growth, Bond, Managed and Money Market Portfolios. SAC is registered
as an investment adviser under the Investment Advisers Act of 1940. SAC is a
partnership whose partners are affiliates of National Life, Provident Mutual
Life Insurance Company ("Provident Mutual"), and The Penn Mutual Life Insurance
Company. National Life's affiliate is currently the managing partner of SAC and
is entitled to the majority share of SAC's profit or loss. The International
Portfolio is advised by Providentmutual Investment Management Company ("PIMC"),
which is also registered with the SEC as an investment adviser under the
Investment Advisers Act of 1940. PIMC has employed The Boston Company Asset
Management, Inc. to provide investment advisory services to the International
Portfolio.

      A full description of the Market Street Fund, its investment objectives
and policies, its risks, expenses, and other aspects of its operation is
contained in the attached Prospectus for the Market Street Fund, which you
should read together with this Prospectus.

OTHER INFORMATION

         Contractual Arrangements. We have entered into or may enter into
agreements with Funds pursuant to which the advisor or distributor pays us a fee
based upon an annual percentage of the average net asset amount we invest on
behalf of the Separate Account and our other separate accounts. These
percentages may differ, and we may be paid a greater percentage by some
investment advisors or distributors than other advisors or distributors. These
agreements reflect administrative services provided by us.

         Investment Results. The investment objectives and policies of certain
Portfolios are similar to the investment objectives and policies of mutual fund
portfolios other than the Portfolios that may be managed by the investment
adviser or manager. The investment results of the Portfolios, however, may be
higher or lower than the results of such other portfolios. There can be no
assurance, and no representation is made, that the investment results of any of
the Funds will be comparable to the investment results of any other portfolio,
even if the other portfolio has the same investment adviser or manager.

         Resolving Material Conflicts. The participation agreements under which
the Funds sell their shares to Subaccounts of the Separate Account contain
varying termination provisions. In general, each party may terminate at its
option with specified advance written notice, and may also terminate in the
event of specific regulatory or business developments.

         Should an agreement between National Life and a Fund terminate, the
Subaccounts which invest in that Fund may not be able to purchase additional
shares of such Fund. In that event, you will no longer be able to transfer
Accumulated Values or allocate Net Premiums to Subaccounts investing in
Portfolios of such Fund.

         Additionally, in certain circumstances, it is possible that a Fund or a
Portfolio of a Fund may refuse to sell its shares to a Subaccount despite the
fact that the participation agreement between the Fund and us has not been
terminated. Should a Fund or Portfolio of such Fund decide not to sell its
shares to us, we will not be able to honor your requests to allocate cash values
or net premiums to Subaccounts investing in shares of that Fund or Portfolio.

         The Funds are available to registered separate accounts of insurance
companies, other than National Life, offering variable annuity and variable life
insurance policies. As a result, there is a possibility that a material conflict
may arise between the interests of Owners with Accumulated Value allocated to
the Separate Account and the owners of life insurance policies and variable
annuities issued by such other

                                       19
<PAGE>   23
companies whose values are allocated to one or more other separate accounts
investing in any one of the Funds.

         In the event of a material conflict, we will take any necessary steps,
including removing the Separate Account from that Fund, to resolve the matter.
The Board of Directors or Trustees of the Funds intend to monitor events in
order to identify any material conflicts that possibly may arise and to
determine what action, if any, should be taken in response to those events or
conflicts. See the individual Fund Prospectuses for more information.

         General. As long as the Policy remains in force, we will pay the Death
Benefit of the Policy, after due proof of the Insured's death (and fulfillment

Unadjusted Death Benefit under the Death Benefit Option that is in effect,
increased by any additional benefits, and decreased by any outstanding Policy
loan and accrued interest and any unpaid Monthly Deductions.
    

         Death Benefit Options. The Policy provides two Death Benefit Options:
Option A and Option B. You select the Death Benefit Option in the application
and may change it as described in "Change in Death Benefit Option," Page .

         Option A. The Unadjusted Death Benefit is equal to the greater of:

            45                215%                            65                120%

</TABLE>

For Attained Ages not shown, the percentages will decrease by a ratable portion
of each full year.

         Illustration of Option A -- For purposes of this illustration, assume
that the Insured is under Attained Age 40 and there is no Policy loan
outstanding.

   
         Under Option A, a Policy with a Face Amount of $200,000 will generally
have an Unadjusted Death Benefit of $200,000. The specified percentage for an
Insured under Attained Age 40 on the Policy Anniversary prior to the date of
death is 250%. Because the Unadjusted Death Benefit must be equal to or greater
than 2.50 times the Accumulated Value, any time the Accumulated Value exceeds
$80,000 the Unadjusted Death Benefit will exceed the Face Amount. Each
additional dollar added to the Accumulated Value will increase the Unadjusted
Death Benefit by $2.50. Thus, a 35 year old Insured with an
    

                                       20
<PAGE>   24

   
Accumulated Value of $90,000 will have an Unadjusted Death Benefit of $225,000
(2.50 x $90,000), and an Accumulated Value of $150,000 will have an Unadjusted
Death Benefit of $375,000 (2.50 x $150,000).
    

         Similarly, any time the Accumulated Value exceeds $80,000, each dollar
taken out of the Accumulated Value will reduce the Unadjusted Death Benefit by
$2.50. If at any time, however, the Accumulated Value multiplied by the
specified percentage is less than the Face Amount, the Unadjusted Death Benefit
will be the Face Amount of the Policy.

         Option B. The Unadjusted Death Benefit is equal to the greater of:

(a) the Face Amount of the Policy plus the Accumulated Value, and

   
(b) the Accumulated Value multiplied by the specified percentage shown in the 
table above.
    

         Illustration of Option B -- For purposes of this illustration, assume
that the Insured is under Attained Age 40 and there is no Policy loan
outstanding.

   
         Under Option B, a Policy with a face amount of $200,000 will generally
have an Unadjusted Death Benefit of $200,000 plus the Accumulated Value. Thus,
for example, a Policy with a $50,000 Accumulated Value will have an Unadjusted
Death Benefit of $250,000 ($200,000 plus $50,000). Since the specified
percentage is 250%, the Unadjusted Death Benefit will be at least 2.50 times the
Accumulated Value. As a result, if the Accumulated Value exceeds $133,333, the
Unadjusted Death Benefit will be greater than the Face Amount plus the
Accumulated Value. Each additional dollar added to the Accumulated Value above
$133,333 will increase the Unadjusted Death Benefit by $2.50. An Insured with an
Accumulated Value of $150,000 will have an Unadjusted Death Benefit of $375,000
(2.50 x $150,000), and an Accumulated Value of $200,000 will yield an Unadjusted
Death Benefit of $500,000 (2.50 x $200,000). Similarly, any time the Accumulated
Value exceeds $133,333, each dollar taken out of the Accumulated Value will
reduce the Unadjusted Death Benefit by $2.50. If at any time, however, the
Accumulated Value multiplied by the specified percentage is less than the Face
Amount plus the Accumulated Value, the Unadjusted Death Benefit will be the Face
Amount plus the Accumulated Value.
    

         At Attained Age 99, Option B automatically becomes Option A.

         Which Death Benefit Option to Choose. If you prefer to have premium
payments and favorable investment performance reflected partly in the form of an
increasing Death Benefit, you should choose Option B. If you are satisfied with
the amount of the Insured's existing insurance coverage and prefer to have
premium payments and favorable investment performance reflected to the maximum
extent in the Accumulated Value, you should choose Option A.

         Change in Death Benefit Option. After the first Policy Year, you may
change the Death Benefit Option in effect by sending us a written request. There
is no charge to change the Death Benefit Option. The effective date of a change
will be the Monthly Policy Date on or next following the date we receive the
written request. Only one change in Death Benefit Option is permitted in any one
Policy Year.

   
     On the effective date of a change in Death Benefit Option, the Face Amount
is adjusted so that there will be no change in the Death Benefit or the Net
Amount at Risk. In the case of a change from Option B to Option A, the Face
Amount must be increased by the Accumulated Value. In the case of a change from
Option A to Option B, the Face Amount must be decreased by the Accumulated
Value. The change from Option A to Option B will not be allowed if it would
reduce the Face Amount to less than the Minimum Face Amount.
    

   
     On the effective date of the change, the Death Benefit, Accumulated Value
and Net Amount at Risk (and therefore the Cost of Insurance Charges) are
unchanged. However, after the effective date of the change, the pattern of
future Death Benefits, Accumulated Value, Net Amount at Risk and Cost of
Insurance Charges will be different than if the change had not been made. In
determining whether a change is appropriate for you, the considerations
described in "Which Death Benefit Option to Choose" above will apply.
    

   
    

   
    

                                       21
<PAGE>   25
   
    

   
    

   
    

         If a change in the Death Benefit Option would result in cumulative
premiums exceeding the maximum premium limitations under the Internal Revenue
Code for life insurance, we will not effect the change.

         A change in the Death Benefit Option may have Federal income tax
consequences. (See "Tax Treatment of Policy Benefits," Page .)

         How the Death Benefit May Vary. The amount of the Death Benefit may
vary with the Accumulated Value. The Death Benefit under Option A will vary with
the Accumulated Value whenever the specified percentage of Accumulated Value
exceeds the Face Amount of the Policy. The Death Benefit under Option B will
always vary with the Accumulated Value because the Unadjusted Death Benefit
equals the greater of (a) the Face Amount plus the Accumulated Value and (b) the
Accumulated Value multiplied by the specified percentage.


ABILITY TO ADJUST FACE AMOUNT

   
         You may, at any time after the first Policy Year, increase or decrease
the Policy's Face Amount by submitting a written application to us. There are
some limits on your ability to effect increases or decreases, which are
discussed below. The effective date of an increase will be the Monthly Policy
Date on or next following our approval of your request. The effective date of a
decrease is the Monthly Policy Date on or next following the date that we
receive your written request. Employee benefit plan Policies may adjust the Face
Amount even in Policy Year 1. An increase or decrease in Face Amount may have
federal tax consequences. (See "Tax Treatment Of Policy Benefits," Page .) The
effect of changes in Face Amount on Policy charges, as well as other
considerations, are described below.
    

         Increase. A request for an increase in Face Amount may not be for less
than $25,000, or such lesser amount required in a particular state (except that
the minimum for employee benefit plans is $2000). You may not increase the Face
Amount after the Insured's Attained Age 85. To obtain the increase, you must
submit an application for the increase and provide evidence satisfactory to us
of the Insured's insurability.

                                       22
<PAGE>   26

         On the effective date of an increase, and taking the increase into
account, the Cash Surrender Value must be at least equal to the Monthly
Deductions then due. If the Cash Surrender Value is not sufficient, the increase
will not take effect until you pay a sufficient additional premium payment to
increase the Cash Surrender Value.

         An increase in the Face Amount will generally affect the total Net
Amount at Risk. This will normally increase the monthly Cost of Insurance
Charges. In addition, the Insured may be in a different Rate Class as to the
increase in insurance coverage. An increase in premium payment or frequency may
be appropriate after an increase in Face Amount. (See "Cost of Insurance
Charge," Page .)

   
         Decrease. The amount of the Face Amount after a decrease cannot be less
than 75% of the largest Face Amount in force at any time in the twelve months
immediately preceding our receipt of your request for the decrease. The Face
Amount after any decrease may not be less than the Minimum Face Amount, which is
generally currently $50,000. If a decrease in the Face Amount would result in
cumulative premiums exceeding the maximum premium limitations applicable for
life insurance under the Internal Revenue Code, we will not allow the decrease.
    

         A decrease in the Face Amount generally will decrease the total Net
Amount at Risk, which will decrease your monthly Cost of Insurance Charges.

         For purposes of determining the Cost of Insurance Charge, any decrease
in the Face Amount will reduce the Face Amount in the following order:

(a) first, the increase in Face Amount provided by the most recent increase;

(b) then the next most recent increases, in inverse chronological order; and
finally

(c) the Initial Face Amount.


HOW THE DURATION OF THE POLICY MAY VARY

         Your Policy will remain in force as long as the Cash Surrender Value of
the Policy is sufficient to pay the Monthly Deductions and the charges under the
Policy. When the Cash Surrender Value is insufficient to pay the charges and the
Grace Period expires without an adequate premium payment by you, the Policy will
lapse and terminate without value. However, during the first five Policy Years
the Policy will not lapse, if you have paid the Minimum Guarantee Premium. You
have certain rights to reinstate your Policy, if it should lapse. (See
"Reinstatement," Page .)

         In addition, an optional Guaranteed Death Benefit Rider is available
which will guarantee that the Policy will not lapse prior to age 70, or 20 years
from the Date of Issue of the Policy, if longer, regardless of investment
performance, if you have paid the Minimum Guarantee Premium as of each Monthly
Policy Date.

ACCUMULATED VALUE

         The Accumulated Value is the total amount of value held under the
Policy at any time. It is equal to the sum of the Policy's values in the
Separate Account and the General Account. The Accumulated Value minus any
applicable Surrender Charge, and minus any outstanding Policy loans and accrued
interest, is equal to the Cash Surrender Value. There is no guaranteed minimum
for the portion of the Accumulated Value in any of the Subaccounts of the
Separate Account. Because the Accumulated Value on any future date depends upon
a number of variables, it cannot be predetermined.

         The Accumulated Value and Cash Surrender Value will reflect:

          -    the Net Premiums paid

          -    the investment performance of the Portfolios you have chosen

                                       23
<PAGE>   27
          -    the crediting of interest on non-loaned Accumulated Value in the
               General Account and amounts held as Collateral in the General
               Account

          -    any transfers

          -    any Withdrawals

          -    any loans

          -    any loan repayments

   
          -    any loan interest charged, and
    

          -    charges assessed on the Policy.

         Determination of Number of Units for the Separate Account. Amounts
allocated, transferred or added to a Subaccount of the Separate Account under a
Policy are used to purchase units of that Subaccount; units are redeemed when
amounts are deducted, transferred or withdrawn. The number of units a Policy has
in a Subaccount equals the number of units purchased minus the number of units
redeemed up to such time. For each Subaccount, the number of units purchased or
redeemed in connection with a particular transaction is determined by dividing
the dollar amount by the unit value.

         Determination of Unit Value. The unit value of a Subaccount is equal to
the unit value on the immediately preceding Valuation Day multiplied by the Net
Investment Factor for that Subaccount on that Valuation Day.

         Net Investment Factor. Each Subaccount of the Separate Account has its
own Net Investment Factor. The Net Investment Factor measures the daily
investment performance of the Subaccount. The factor will increase or decrease,
as appropriate, to reflect net investment income and capital gains or losses,
realized and unrealized, for the securities of the underlying portfolio or
series.

         The asset charge for mortality and expense risks will be deducted in
determining the applicable Net Investment Factor. (See "Charges and Deductions -
Mortality and Expense Risk Charge," Page .)

         Calculation of Accumulated Value. The Accumulated Value is determined
first on the Date of Issue and thereafter on each Valuation Day. On the Date of
Issue, the Accumulated Value will be the Net Premiums received, plus any
earnings prior to the Date of Issue, less any Monthly Deductions due on the Date
of Issue. On each Valuation Day after the Date of Issue, the Accumulated Value
will be:

         (1)      The aggregate of the values attributable to the Policy in the
                  Separate Account, determined by multiplying the number of
                  units the Policy has in each Subaccount of the Separate
                  Account by such Subaccount's unit value on that date; plus

         (2)      The value attributable to the Policy in the General Account
                  (See "The General Account," Page .)


PAYMENT AND ALLOCATION OF PREMIUMS

   
         Issuance of a Policy. To purchase a Policy, you must apply to us
through a licensed National Life agent who is also a registered representative
of Equity Services, Inc. ("ESI") or a broker/dealer having a Selling Agreement
with ESI. If you do not pay the Minimum Initial Premium with your written
application, it must be paid when the Policy is delivered.  If the premium paid
is less than the Minimum Initial Premium, the balance of the Minimum Initial
Premium must be received within five days, or all premiums will be refunded.
    

         The Minimum Face Amount of a Policy under our rules is generally
$50,000; however, exceptions may be made for employee benefit plans. We may
revise our rules from time to time to specify a different Minimum Face Amount
for subsequently issued policies. A Policy will be issued only on

                                       24
<PAGE>   28

Insureds who have an Issue Age of 85 or less and who provide us with
satisfactory evidence of insurability. Acceptance is subject to our underwriting
rules. We may reject an application for any reason permitted by law. (See
"Distribution of Policies," Page .)

   
         From the time the application for a Policy is signed until the time the
Policy is issued, you can, subject to our underwriting rules, obtain temporary
insurance protection, pending issuance of the Policy, if you are able to 
answer "no" to the Health Questions of the Receipt & Temporary Life Insurance
Agreement and submitting (a) a complete Application including any medical
questionnaire required, and (b) payment of the Minimum Initial Premium. 
    

         The amount of coverage under the Receipt & Temporary Life Insurance
Agreement is the lesser of the Face Amount applied for or $1,000,000 ($100,000
in the case of proposed Insureds age 70 or over). Coverage under the agreement
will end on the earliest of:

(a) the 90th day from the date of the agreement;

(b) the date that insurance takes effect under the Policy;

(c) the date a policy, other than as applied for, is offered to you;

(d) three days from the date we mail a notice of termination of coverage;

(e) the time you first learn that we have terminated the temporary life
insurance; or

(f) the time you withdraw the application for life insurance.

         We offer a one time credit on conversions of eligible National Life
term insurance policies to a VariTrak Policy. If the term policy being converted
has been in force for at least twelve months, the amount of the credit is 12% of
a target amount used to determine commission payments. If the term policy being
converted has been in force for less than twelve months, the credit will be
prorated based on the number of months the term policy has been outstanding at
the time of conversion. For GRT term policies, the credit will be 18% of the
target amount used to determine commission payments if the GRT term policy has
been in force for at least two years but not more than five years. For GRT term
policies in force for less than two years, the credit is 0.5% per month for each
month in the first year, and 1.0% per month for each month in the second year.
For GRT policies in force more than five years, the credit decreases from 18% by
0.5% for each month beyond five years, until it becomes zero at the end of year
eight.

         The amount of the credit will be added to the initial premium payment,
if any, you pay and will be treated as part of the Initial Premium for the
Policy. Thus, the credit will be included in premium payments for purposes of
calculating and deducting the Premium Tax Charge. If you surrender your Policy,
we will not recapture the credit. We will not include the amount of the credit
for purposes of calculating agent compensation for the sale of the Policy.

         We also offer a one time credit to Home Office employees who purchase a
VariTrak Policy, as both Owner and Insured. This one time credit is calculated
differently from the credit described above; in particular, the amount of the
credit will be 50% of the target premium used in the calculation of commissions
on the Policy. Otherwise, the credit will be treated in the same manner as the
credit described above.

         Amount and Timing of Premiums. Each premium payment must be at least
$50. You have considerable flexibility in determining the amount and frequency
of premium payments, within the limits discussed below.

   
         You will at the time of application select a Planned Periodic Premium
schedule, based on a periodic billing mode of annual, semi-annual, or quarterly
payments. You may request us to send a premium reminder notice at the specified
interval. You may change the Planned Periodic Premium frequency and amount.
Also, under an Automatic Payment Plan, you can select a monthly payment
schedule pursuant to which premium payments will be automatically deducted from
a bank account or other source, rather than being "billed." We may allow, in
certain situations, Automatic Payment Plan payments of less than $50. We may
require that Automatic Payment Plans be set up for at least the Minimum Monthly
Premium.
    

                                       25
<PAGE>   29

         You are not required to pay the Planned Periodic Premiums in accordance
with the specified schedule. You may pay premiums whenever you like, and in any
amount (subject to the $50 minimum and the limitations described in the next
section). Payment of the Planned Periodic Premiums will not, however, guarantee
that the Policy will remain in force. Instead, the duration of the Policy
depends upon the Policy's Cash Surrender Value. Thus, even if you pay the
Planned Periodic Premiums, the Policy will lapse whenever the Cash Surrender
Value is insufficient to pay the Monthly Deductions and any other charges under
the Policy and if a Grace Period expires without an adequate payment by you
(unless the Policy is in its first five years, or you have purchased the
Guaranteed Death Benefit Rider, in either case so long as you have paid the
Minimum Guarantee Premium).

         Any payments you make while there is an outstanding Policy loan will be
applied as premium payments rather than loan repayments, unless you notify us in
writing that the amount is to be applied as a loan repayment. You may not make
premium payments after the Insured reaches Attained Age 99. However, we permit
loan repayments after Attained Age 99.

         Higher premium payments under Death Benefit Option A, until the
applicable percentage of Accumulated Value exceeds the Face Amount, will
generally result in a lower Net Amount at Risk. This will produce lower Cost of
Insurance Charges against the Policy. Conversely, lower premium payments in this
situation will result in a higher Net Amount at Risk, which will result in
higher Cost of Insurance Charges under the Policy.

         Under Death Benefit Option B, until the applicable percentage of
Accumulated Value exceeds the Face Amount plus the Accumulated Value, the level
of premium payments will not affect the Net Amount at Risk. However, both the
Accumulated Value and Death Benefit will be higher if premium payments are
higher, and lower if premium payments are lower.

         Under either Death Benefit Option, if the Unadjusted Death Benefit is
the applicable percentage of Accumulated Value, then higher premium payments
will result in a higher Net Amount at Risk, and higher Cost of Insurance
Charges. Lower premium payments will result in a lower Net Amount at Risk, and
lower Cost of Insurance Charges.

   
         Premium Limitations. The Internal Revenue Code of 1986 (the "Code")
provides for exclusion of the Death Benefit from gross income if total premium
payments do not exceed certain stated limits. In no event can the total of all
premiums paid under a Policy exceed these limits. If at any time you pay a
premium which would result in total premiums exceeding the limits, we will only
accept that portion of the premium which would make total premiums equal the
maximum amount which may be paid under the Policy. We will promptly refund the
excess to you. In cases of premiums paid by check, we will wait until your check
has cleared. If you have an outstanding loan, we may instead apply the payment
as a loan repayment. Even if total premiums were to exceed the maximum premium
limitations established by the Code, the excess of (a) a Policy's Unadjusted
Death Benefit over (b) the Policy's Cash Surrender Value plus outstanding Policy
loans and accrued interest, would still be excludable from gross income under
the Code.
    

         The maximum premium limitations set forth in the Code depend in part
upon the amount of the Unadjusted Death Benefit at any time. As a result, any
Policy changes which affect the amount of the Unadjusted Death Benefit may
affect whether cumulative premiums paid under the Policy exceed the maximum
premium limitations. To the extent that any such change would result in
cumulative premiums exceeding the maximum premium limitations, we will not
effect the change. (See "Federal Income Tax Considerations," Page .)

         Unless the Insured provides satisfactory evidence of insurability, we
may limit the amount of any premium payment if it increases the Unadjusted Death
Benefit more than it increases the Accumulated Value.

                                       26
<PAGE>   30

         Allocation of Net Premiums. The Net Premium equals the premium paid
less the Premium Tax Charge. In your application for the Policy, you will
indicate how Net Premiums should be allocated among the Subaccounts of the
Separate Account and/or the General Account. You may change these allocations at
any time by giving us written notice at our Home Office, or if you have elected
the telephone transaction privilege, by telephone instructions (See "Telephone
Transaction Privilege," Page .) You must make allocations in whole number
percentages of at least 5%, and the sum of the allocation percentages must be
100%. We will allocate Net Premiums as of the Valuation Date we receive the
premium at our Home Office, based on the allocation percentages then in effect,
except during the free look period.

         We will allocate any portion of the Initial Premium and any subsequent
premiums we receive before the end of the free look period which are to be
allocated to the Separate Account, to the Money Market Subaccount. For this
purpose, we will assume that the free look period will end 20 days after the
date the Policy is issued. On the first Valuation Date following 20 days after
issue of the Policy, we will allocate the amount in the Money Market Subaccount
to each of the Subaccounts selected in the application based on your
instructions.

         For example, assume a Policy was issued with Net Premiums to be
allocated 25% to the Managed Subaccount, 25% to the Bond Subaccount and 50% to
the General Account. During the period stated above, 50% (25% + 25%) of the Net
Premiums will be allocated to the Money Market Subaccount. At the end of such
period, 50% (25% / 50%) of the amount in the Money Market Subaccount will be
transferred to the Managed Subaccount and 50% to the Bond Subaccount.

         The values of the Subaccounts will vary with their investment
experience. You bear the entire investment risk. You should periodically review
your allocation percentages in light of market conditions and your overall
financial objectives.

         Transfers. You may transfer the Accumulated Value between and among the
Subaccounts of the Separate Account and the General Account by sending us a
written transfer request, or if you have elected the telephone transaction
privilege, by telephone instructions to us. (See "Telephone Transaction
Privilege," Page .) Transfers between and among the Subaccounts of the Separate
Account and the General Account are made as of the Valuation Day that the
request for transfer is received at the Home Office. You may, at any time,
transfer all or part of the amount in one of the Subaccounts of the Separate
Account to another Subaccount and/or to the General Account. For transfers from
the General Account to the Separate Account, see "Transfers from General
Account," Page .

         Currently an unlimited number of transfers are permitted without
charge. We have no current intent to impose a transfer charge in the foreseeable
future. However, we may, after giving you prior notice, change this policy so as
to deduct a $25 transfer charge from each transfer in excess of the fifth
transfer during any one Policy Year. All transfers requested during one
Valuation Period are treated as one transfer transaction. If a transfer charge
is adopted in the future, these types of transfers would not be subject to a
transfer charge and would not count against the five free transfers in any
Policy Year:

          -    transfers resulting from Policy loans

          -    transfers resulting from the operation of the dollar cost
               averaging or portfolio rebalancing features

          -    transfers resulting from the exercise of the transfer rights
               described on page____ (see "Policy Rights - Other Transfer
               Rights," Page ), and 

          -    the reallocation from the Money Market Subaccount following the
               free look period.

Under present law, transfers are not taxable transactions.

         Policy Lapse. The failure to make a premium payment will not itself
cause a Policy to lapse. A Policy will lapse only when the Cash Surrender Value
is insufficient to cover the Monthly Deductions and other charges under the
Policy and the Grace Period expires without a sufficient payment. During the
first five Policy Years, the Policy will not lapse so long as you pay the
Minimum Guarantee Premium.

                                       27
<PAGE>   31
   
         In addition, if you purchase the Guaranteed Death Benefit Rider, and
pay the Minimum Guarantee Premium as of each Monthly Policy Date, your Policy
will not lapse prior to the Insured's Attained Age 70, or 20 years from the Date
of Issue of the Policy if longer, regardless of whether the Cash Surrender Value
is sufficient to cover the Monthly Deductions. If you purchase the Guaranteed
Death Benefit Rider, your Minimum Guarantee Premium will be higher than if you
do not purchase the Guaranteed Death Benefit Rider. (See "Optional Benefits -
Guaranteed Death Benefit," Page .)
    

         The Policy provides for a 61-day Grace Period that is measured from the
date we send a lapse notice. The Policy does not lapse, and the insurance
coverage continues, until the expiration of this Grace Period. To prevent lapse,
you must during the Grace Period pay a premium equal to the sum of any amount by
which the past Monthly Deductions have been in excess of Cash Surrender Value,
plus three times the Monthly Deduction due the date the Grace Period began. Our
notice will specify the payment required to keep the Policy in force. Failure to
make a payment at least equal to the required amount within the Grace Period
will result in lapse of the Policy without value.

         Reinstatement. A Policy that lapses without value may be reinstated at
any time within five years (or longer period required in a particular state)
after the beginning of the Grace Period. To do so, you must submit evidence of
the Insured's insurability satisfactory to us and pay an amount sufficient to
provide for two times the Monthly Deduction due on the date the Grace Period
began plus three times the Monthly Deduction due on the effective date of
reinstatement. The effective date of reinstatement, unless otherwise required by
state law, will be the Monthly Policy Date on or next following the date your
reinstatement application is approved. Upon reinstatement, the Accumulated Value
will be based upon the premium paid to reinstate the Policy. The Policy will be
reinstated with the same Date of Issue as it had prior to the lapse. Neither the
five year no lapse guarantee nor the Death Benefit Guarantee Rider may be
reinstated.

         Specialized Uses of the Policy. Because the Policy provides for an
accumulation of cash value as well as a death benefit, the Policy can be used
for various individual and business financial planning purposes. Purchasing the
Policy in part for such purposes entails certain risks. For example, if the
investment performance of the chosen Subaccounts is poorer than expected or if
sufficient premiums are not paid, the Policy may lapse or may not accumulate
sufficient Accumulated Value or Cash Surrender Value to fund the purpose for
which the Policy was purchased. Withdrawals and Policy loans may significantly
affect current and future Accumulated Value, Cash Surrender Value, or Death
Benefit proceeds. Depending upon Subaccount investment performance and the
amount of a Policy loan, the loan may cause a Policy to lapse. Because the
Policy is designed to provide benefits on a long-term basis, before purchasing a
Policy for a specialized purpose you should consider whether the long-term
nature of the Policy is consistent with your purpose. Using a Policy for a
specialized purpose may have tax consequences. (See "Federal Income Tax
Considerations," Page .)

         For Policies that are intended to be used in STEP plans, you should be
aware that there is a risk that the intended tax consequences of such a plan may
not be realized. In two audits, the Internal Revenue Service has proposed tax
treatment less advantageous than intended, and those matters are currently in
litigation. The plans under audit may have considerable differences from those
you may be considering, and the litigation regarding such plans may or may not
be controlling with respect to STEP plans you may implement. We do not guarantee
any particular tax consequences of any use of the Policies, including but not
limited to use in STEP plans. We recommend that you seek independent tax advice
with respect to applications in which you seek particular tax consequences.

                             CHARGES AND DEDUCTIONS


      Charges will be deducted in connection with the Policy to compensate us
for:

         (a) providing the insurance and other benefits set forth in the Policy;

         (b) administering the Policy;

         (c) assuming certain mortality and other risks in connection with the
             Policy; and

         (d) incurring expenses in distributing the Policy including costs
             associated with printing prospectuses and sales literature and
             sales compensation.

         We may realize a profit from any charges. We may use any profit for any
purpose, including payment of distribution expenses.

PREMIUM TAX CHARGE

         We will deduct 3.25% from each premium payment prior to allocation of
Net Premiums, to cover state premium taxes and the federal DAC Tax. For
qualified employee benefit plans, we will deduct 2.0% of each premium rather
than 3.25%.

         The federal DAC Tax is a tax attributable to certain "policy
acquisition expenses" under Internal Revenue Code Section 848. Section 848 in
effect accelerates the realization of income we receive from the Policies, and
therefore the payment of federal income taxes on that income. The economic
consequence of Section 848 is, therefore, an increase in the tax burden borne by
us that is attributable to the Policies.

SURRENDER CHARGE

         We impose a Surrender Charge, which consists of a Deferred
Administrative Charge and a Deferred Sales Charge, if the Policy is surrendered
or lapses at any time before the end of the fifteenth Policy Year.

   
         Deferred Administrative Charge. The Deferred Administrative Charge
varies by Issue Age, and is based on the Initial Face Amount. After the first
five Policy Years, it declines linearly by Policy Month through the end of 
Policy Year 15, after which it is zero. Charges per $1,000 of Face Amount for
sample Issue Ages are shown below:
    

<TABLE>

                           25-85                          $2.00
</TABLE>


         For Issue Ages not shown, the charge will increase by a ratable portion
for each full year. The Deferred Administrative Charge has been designed to
cover actual expenses for the issue and underwriting of Policies, and is not
intended to produce a profit.

   
         Deferred Sales Charge. The Deferred Sales Charge will not exceed the
Maximum Deferred Sales Charge specified in the Policy. 
    

                                       29
<PAGE>   33

   
    

         The actual Deferred Sales Charge will equal the lesser of:

   
         (a) the maximum discussed in the previous sentence, and
    

         (b) an amount equal to the sum of:

                  (i) 30% of the premiums actually received up to one Surrender
                      Charge target premium, plus

                  (ii) 10% of all premiums paid in excess of this amount but not
                       greater than twice this amount, plus

                  (iii) 9% of all premiums paid in excess of twice this amount.

   
      Appendix B to this Prospectus contains a table showing the Surrender
Charge target premium and the Maximum Deferred Sales Charge for male and female
nonsmokers and smokers of each age at the time a policy is issued, expressed as
a dollar amount per $1000 of initial face amount.
    

         To illustrate the calculation of a Policy's Surrender Charge, assume
         that the Policy is issued to a male nonsmoker, Issue Age 45, with a
         Face Amount of $100,000. Assume that the Surrender Charge target
         premium ("SCTP") is $1,652, the initial Maximum Deferred Sales Charge
         is $826 (50% of $1,652) and the Insured pays annual premiums of $1,500
         at the beginning of each Policy Year. This example will illustrate
         surrenders in the first five Policy Years and in the first month of the
         eighth Policy Year.

         Deferred Administrative Charge. The Deferred Administrative Charge for
         the first five Policy Years is $200. This is calculated by applying the
         charge of $2.00 per $1,000 of Face Amount for Issue Age 45 from the
         schedule above to the Face Amount of $100,000 ($2.00 x
         (100,000/1,000)). The Deferred Administrative Charge reduces linearly
         by Policy Month in Policy Years 6 through 15. Linear reduction is
         equivalent to a reduction each month of 1/121st of the initial charge.
         For example, the Deferred Administrative Charge in the first month of
         the eighth Policy Year (the 25th month after the end of the 5th Policy
         Year) will be $158.68 ($200 - ($200 x (25/121)). After completion of
         the 15th Policy Year, the Deferred Administrative Charge is zero. The
         schedule of Deferred Administrative Charges in effect for the first
         fifteen Policy Years is shown in the Policy.

         Deferred Sales Charge. The Deferred Sales Charge is the lesser of the
         Maximum Deferred Sales Charge and an amount calculated based on the
         Insured's actual premium payments. The Maximum Deferred Sales Charge in
         effect for the first five Policy Years is $826. The Maximum Deferred
         Sales Charge reduces linearly by month in Policy Years 6 through 15.
         Linear reduction is equivalent to a reduction each month of 1/121st of
         the initial charge. For example, the Maximum Deferred Sales Charge in
         the first month of the 8th Policy Year (the 25th month after the end of
         the 5th Policy Year) will be $655.34 ($826 - ($826 x (25/121))). After
         the completion of the 15th Policy Year, the Maximum Deferred Sales
         Charge is $0. The schedule of Maximum Deferred Sales Charges in effect
         for the first fifteen Policy Years is shown in the Policy.

         The Maximum Deferred Sales Charge is compared to an amount calculated
         as a function of premiums actually paid and the SCTP. The amount is
         calculated as the sum of 30% of premiums paid up to the first SCTP
         ($1,652), 10% of premiums paid in excess of the first SCTP but not more
         than two SCTP's (from $1,653 to $3,304), and 9% of premiums paid in
         excess of two SCTP's (above $3,304). As an example, the calculated
         amounts in Policy Years 1 through 5 and Policy Year 8 would be as
         follows:

         The total calculated amount would then be compared to the Maximum
         Deferred Sales Charge to determine the Deferred Sales Charge actually
         imposed. For example, the Deferred Sales Charge in the first five years
         would be the following:
<TABLE>
<CAPTION>

                                  (A)                            (B)

         1                      $  450.00                        $826.00                         $450.00
         2                      $  630.40                        $826.00                         $630.40
         3                      $  768.44                        $826.00                         $768.44
         4                      $  903.44                        $826.00                         $826.00
         5                      $1,038.44                        $826.00                         $826.00
</TABLE>

         In this example, the charge based on SCTP is less than the Maximum
         Deferred Sales Charge until the fourth Policy Year. Thereafter, the
         Maximum Deferred Sales Charge is less than the charge based on SCTP.
         For example, the Deferred Sales Charge in the first month of the eighth
         Policy Year will be the Maximum Deferred Sales Charge of $655.34
         (calculated above) since this is less than $1,443.44 (the calculated
         amount based on premiums paid).

MONTHLY DEDUCTIONS

         We will deduct charges from the Accumulated Value on the Date of Issue
and on each Monthly Policy Date. The Monthly Deduction consists of three
components:

         (a) the Cost of Insurance Charge

         (b) the Monthly Administrative Charge, and

         (c) the cost of any additional benefits provided by Rider.

         The Monthly Deduction may vary in amount from Policy Month to Policy
Month. We will take the Monthly Deduction on a pro rata basis from the
Subaccounts of the Separate Account and the General Account, unless you have
requested at the time of application, or later request in writing, that we take
the Monthly Deductions from the Money Market Subaccount. If we cannot take a
Monthly Deduction from the Money Market Subaccount, where you have so asked, we
will take the amount of the deduction in excess of the Accumulated Value
available in the Money Market Subaccount on a pro rata basis from Accumulated
Value in the Subaccounts of the Separate Account and the General Account.

         Cost of Insurance Charge. We calculate the monthly Cost of Insurance
Charge by multiplying the applicable cost of insurance rate or rates by the Net
Amount at Risk for each Policy Month. Because both the Net Amount at Risk and
the variables that determine the cost of insurance rate, such as the age of the
Insured and the Duration of the Policy, may vary, the Cost of Insurance Charge
will likely be different from month to month.

                  Net Amount at Risk. The Net Amount at Risk on any Monthly
         Policy Date is approximately the amount by which the Unadjusted Death
         Benefit on that Monthly Policy Date exceeds the Accumulated Value. It
         measures the amount National Life would have to pay in excess of the
         Policy's Value if the Insured died. The actual calculation uses the
         Unadjusted Death Benefit divided by 1.00327234, to take into account
         assumed monthly earnings at an annual rate of 4%. We calculate the Net
         Amount at Risk separately for the Initial Face Amount and any increases
         in Face Amount. In determining the Net Amount at Risk for each
         increment of Face Amount, we first consider the Accumulated Value part
         of the Initial Face Amount. If the Accumulated Value exceeds the
         Initial Face Amount, we consider it as part of any increases in Face
         Amount in the order such increases took effect.

                                       31
<PAGE>   35

         Any change in the Net Amount at Risk will affect the total Cost of
Insurance Charges paid by the Owner.

         Guaranteed Maximum Cost of Insurance Rates. The guaranteed maximum cost
of insurance rates will be set forth in your Policy, and will depend on:

          -    the Insured's Attained Age

          -    the Insured's sex

          -    the Insured's Rate Class, and

          -    the 1980 Commissioners Standard Ordinary Smoker/Nonsmoker
               Mortality Table.

         For Policies issued in states which require "unisex" policies or in
conjunction with employee benefit plans, the guaranteed maximum cost of
insurance rate will use the 1980 Commissioners Standard Ordinary Mortality
Tables NB and SB.

         Current Cost of Insurance Rates and How They are Determined. The actual
cost of insurance rates used ("current rates") will depend on:

          -    the Insured's Issue Age

          -    the Insured's sex

          -    the Insured's Rate Class

          -    the Policy's Duration, and

          -    the Policy's size.

         Generally, the current cost of insurance rate for a given Attained Age
will be less than for an Insured whose Policy was issued more than 10 years ago,
than for an Insured whose Policy was issued less than 10 years ago, other
factors being equal. We periodically review the adequacy of our current cost of
insurance rates and may adjust their level. However, the current rates will
never exceed guaranteed maximum cost of insurance rates. Any change in the
current cost of insurance rates will apply to all persons of the same Issue Age,
sex, and Rate Class, and with Policies of the same Duration and size.

   
         We use separate cost of insurance rates for the Initial Face Amount and
any increases in Face Amount. For the Initial Face Amount we use the rate for
the Insured's Rate Class on the Date of Issue. For each increase in Face Amount,
we use the rate for the Insured's Rate Class at the time of the increase. If the
Unadjusted Death Benefit is calculated as the Accumulated Value times the
specified percentage, we use the rate for the Rate Class for the Initial Face
Amount for the amount of the Unadjusted Death Benefit in excess of the total
Face Amount for Option A, and in excess of the total Face Amount plus the
Accumulated Value for Option B.
    

         We may also issue Policies on a guaranteed issue basis, where no
medical underwriting is required prior to issuance of a Policy. Current cost of
insurance rates for Policies issued on a guaranteed issue basis may be higher
than current cost of insurance rates for healthy Insureds who undergo medical
underwriting.

         Rate Class. The Rate Class of the Insured will affect both the
guaranteed and current cost of insurance rates. We currently place Insureds into
the following rate classes:

          -    preferred nonsmoker

          -    standard nonsmoker

          -    smoker

          -    juvenile, and

          -    substandard.

   
         Smoker and substandard classes reflect higher mortality risks. In an
otherwise identical Policy, an Insured in a preferred or standard class will
have a lower Cost of Insurance Charge than an Insured in a substandard class
with higher mortality risks. Nonsmoking Insureds will generally incur lower cost
of insurance rates than Insureds who are classified as smokers.
    

                                       32
<PAGE>   36
   
         The nonsmoker designation is not available for Insureds under Attained
Age 20. Shortly before an Insured attains age 20, we will notify the Insured
about possible classification as a nonsmoker and direct the Insured to his or
her agent to initiate a change in Rate Class. If the Insured qualifies as a
nonsmoker, we will change the guaranteed and current cost of insurance rates to
reflect the nonsmoker classification.
    

         Current cost of insurance rates will also vary by Policy size, in the
following bands:

   
          -    those with Face Amounts less than $250,000
    

   
          -    those with Face Amounts between $250,000 and
               $999,999, inclusive; and
    

   
          -    those with Face Amounts of $1,000,000 and over.
    

         Cost of insurance rates will be lower as the Policy size band is
larger.

         Monthly Administrative Charge. We deduct a Monthly Administrative
Charge of $7.50 from the Accumulated Value on the Date of Issue and each Monthly
Policy Date as part of the Monthly Deduction to help defray the expenses
incurred in administering the Policy. In Texas, the Monthly Administrative
Charge may be increased, but is guaranteed never to exceed $7.50 plus $0.07 per
$1,000 of Face Amount.

         Optional Benefit Charges. The Monthly Deduction will include charges
for any additional benefits added to the Policy. The monthly charges will be
specified in the applicable Rider. The available Riders are listed under
"Optional Benefits", on Page   below.

         Bonus. We currently intend to reduce the Monthly Deductions starting in
the eleventh Policy Year by an amount equal to 0.50% per annum of the
Accumulated Value in the Separate Account. This bonus is not guaranteed (except
as required by the state of issue), however. It will only be continued if our
mortality and expense experience with the Policies justifies it. We may notify
you before the commencement of the eleventh Policy Year that we intend to
discontinue the bonus.

         The bonus is calculated on each Monthly Policy Date as .041572% (the
monthly equivalent of 0.50% per annum) of the Accumulated Value in the Separate
Account on the just prior Monthly Policy Date. For example, if the Accumulated
Value in the Separate Account on the just prior Monthly Policy Date is $10,000,
then the bonus calculated for the current Monthly Policy Date will be $4.16
($10,000 X .00041572). To calculate the Monthly Deduction for the current
Monthly Policy Date, we net the $4.16 bonus against the Monthly Deductions for
Cost of Insurance, the Monthly Administrative Charge, and charges for any
Optional Benefits.

MORTALITY AND EXPENSE RISK CHARGE

         We deduct a daily charge from the Separate Account at an annual rate of
0.90% (or a daily rate of .0024548%) of the average daily net assets of each
Subaccount of the Separate Account. This charge compensates us for the mortality
and expense risks assumed in connection with the Policy. The mortality risk we
assume is that insured persons may live for a shorter time than projected. This
means we would pay greater death benefits than expected in relation to the
amount of premiums received. The expense risk we assume is that expenses
incurred in issuing and administering the Policies will exceed the
administrative charges deducted from the Policy. We may make a profit from
deducting this charge. Any profit may be used to finance distribution expenses.

                                       33
<PAGE>   37

WITHDRAWAL CHARGE

         We will assess on each Withdrawal a charge equal to the lesser of 2% of
the Withdrawal amount and $25. We will deduct this Withdrawal Charge from the
Withdrawal amount.

TRANSFER CHARGE

         Currently, unlimited transfers are permitted among the Subaccounts, or
from the Separate Account to the General Account. Transfers from the General
Account to the Separate Account are permitted within the limits described on
Page . Currently there is no charge for any transfers. We have no present
intention to impose a transfer charge in the foreseeable future. However, we may
impose in the future a transfer charge of $25 on each transfer in excess of five
transfers in any Policy Year. The Transfer Charge would be imposed to compensate
us for the costs of processing such transfers, and would not be designed to
produce a profit.

         If we impose a transfer charge in the future, we will deduct it from
the amount being transferred. We would treat all transfers requested on the same
Valuation Date as one transfer transaction. Any future transfer charge will not
apply to transfers resulting from:

          -    Policy loans

          -    the exercise of the transfer rights described on page ____

          -    the initial reallocation of account values from the Money Market
               Subaccount to other Subaccounts, and

          -    any transfers made pursuant to the Dollar Cost Averaging and
               Portfolio Rebalancing features.

The transfers listed above also will not count against the five free transfers
in any Policy Year.

PROJECTION REPORT CHARGE

         We may impose a charge for each projection report you request. This
report will project future values and future Death Benefits for the Policy. We
will notify you in advance of the amount of the charge. You may elect to pay the
charge in advance. If not paid in advance, we will deduct this charge from the
Subaccounts of the Separate Account and/or the General Account in proportion to
their Accumulated Values on the date of the deduction.


OTHER CHARGES

         The Separate Account purchases shares of the Funds at net asset value.
The net asset value of those shares reflect management fees and expenses already
deducted from the assets of the Funds' Portfolios. Historical expense ratio
information for the Funds is presented in the "Summary of Policy Expenses"
section on page above. More detailed information is contained in the Funds'
Prospectuses which accompany this Prospectus.

                          POLICY RIGHTS AND PRIVILEGES

LOAN PRIVILEGES

   
         General. You may at any time after the first year (and during the first
year where required by law) borrow money from us using the Policy as the only
security for the loan. The maximum amount you may borrow is the Policy's Cash
Surrender Value on the date we receive your loan request, minus three times the
Monthly Deduction for the most recent Monthly Policy Date. You may repay all or
a portion of a loan and accrued interest at any time, if the Insured is alive.
To take a loan, you should send us a written request at our Home Office. If you
have elected the telephone transaction privilege, you may also request a loan
over the telephone. We limit the amount of a Policy loan you can take by
telephone to $25,000. (See "Telephone
    

                                       34
<PAGE>   38

Transaction Privilege," Page .) We will normally pay loan proceeds within seven
days of a valid loan request.

         Interest Rate Charged. We charge interest on Policy loans at the fixed
rate of 6% per year. We charge interest from the date of the loan and add it to
the loan balance at the end of the Policy Year. When this interest is added to
the loan balance, it bears interest at the same rate..

   
         Allocation of Loans and Collateral. When you take a Policy loan, we
hold Accumulated Value in the General Account as Collateral for the Policy loan.
You may specify how you would like the Accumulated Value to be taken from the
Subaccounts of the Separate Account to serve as Collateral. If you do not so
specify, we will allocate the Policy loan to the Subaccounts in proportion to
the Accumulated Value in the Subaccounts. If the Accumulated Value in one or
more of the Subaccounts is insufficient to carry out your instructions, we will
not process the loan until we receive further instructions from you. Non-loaned
Accumulated Value in the General Account will become Collateral for a loan only
to the extent that the Accumulated Value in the Separate Account is
insufficient. 
    

         The Collateral for a Policy loan will initially be the loan amount.
Loan interest will be added to the Policy loan. We will take additional
Collateral for the loan interest pro rata from the Subaccounts of the Separate
Account, and then, if the amounts in the Separate Account are insufficient, from
the non-loaned portion of the General Account. At any time, the amount of the
outstanding loan under a Policy equals the sum of all loans (including due and
unpaid interest added to the loan balance) minus any loan repayments.

         Interest Credited to Amounts Held as Collateral. As long as the Policy
is in force, we will credit the amount held in the General Account as Collateral
with interest at effective annual rates we declare, but not less than 4% or such
higher minimum rate required under state law. The rate will apply to the
calendar year which follows the date of determination.

         Bonus. In Policy Years 11 and thereafter, we currently intend to credit
interest on amounts held in the General Account as Collateral at a rate 0.50%
per annum higher than for similar amounts for Policies still in their first ten
Policy Years. This bonus is not guaranteed, however. Upon prior notice to Owners
we may, in our sole discretion, decide not to credit the bonus.

         Preferred Policy Loans. We also currently intend to make preferred
Policy loans available on the later of the Insured's Attained Age 65 and the
beginning of Policy Year 21. The maximum amounts of these preferred loans will
be 5% of Accumulated Value per year, with a cumulative maximum of 50% of
Accumulated Value. For these preferred Policy loans, the amounts held as
Collateral in the General Account will be credited with interest at an annual
rate of 6%. If both preferred and non-preferred loans exist at the same time, we
will first apply any loan repayment to the non-preferred loan. We are not
obligated to make preferred loans available, and will make such loans available
in our sole discretion. Preferred loans may not be treated as indebtedness for
federal income tax purposes.

   
         Effect of Policy Loan. Policy loans, whether or not repaid, will have a
permanent effect on the Accumulated Value and the Cash Surrender Value, and may
permanently affect the Death Benefit of your Policy. The effect on the
Accumulated Value and Death Benefit could be favorable or unfavorable. It will
depend on whether the investment performance of the Subaccounts, and the
interest credited to the non-loaned Accumulated Value in the General
Account, is less than or greater than the interest being credited on the amounts
held as Collateral in the General Account. Compared to a Policy under which no
loan is made, values under a Policy will be lower when the credited interest
rate on Collateral is less than the investment experience of assets held in the
Separate Account and interest credited to the non-Collateral Accumulated Value
in the General Account. The longer a loan is outstanding, the greater the effect
a Policy loan is likely to have. The Death Benefit will be reduced by the amount
of any outstanding Policy loan.
    

                                       35
<PAGE>   39

         Loan Repayments. We will assume that any payments you make while there
is an outstanding Policy loan are premium payments, rather than loan repayments,
unless you specify in writing that a payment is a loan repayment. In the event
of a loan repayment, the amount held as Collateral in the General Account will
be reduced by an amount equal to the repayment, and such amount will be
transferred to the Subaccounts of the Separate Account and to the non-loaned
portion of the General Account based on the Net Premium allocations in effect at
the time of the repayment.

         Lapse With Loans Outstanding. The amount of an outstanding loan under a
Policy plus any accrued interest on outstanding loans is not part of Cash
Surrender Value. Therefore, the larger the amount of an outstanding loan, the
more likely it is that the Policy could lapse. (See "How the Duration of the
Policy May Vary," Page and "Policy Lapse," Page .) In addition, if the Policy is
not a Modified Endowment Policy, lapse of the Policy with outstanding loans may
result in adverse federal income tax consequences. (See "Tax Treatment of Policy
Benefits," Page .)

         Tax Considerations. Any loans taken from a "Modified Endowment
Contract" will be treated as a taxable distribution. In addition, with certain
exceptions, a 10% additional income tax penalty will be imposed on the portion
of any loan that is included in income. (See "Distributions from Policies
Classified as Modified Endowment Contracts," Page .)

SURRENDER PRIVILEGE

         You may surrender your Policy for its Cash Surrender Value at any time
before the death of the Insured. The Cash Surrender Value is the Accumulated
Value minus any Policy loan and accrued interest and less any Surrender Charge.
We will calculate the Cash Surrender Value on the Valuation Day we receive, at
our Home Office, your signed written surrender request, and the Policy. You may
not request a surrender over the telephone. Coverage under the Policy will end
on the day you mail or otherwise send your written surrender request and the
Policy to us. We will ordinarily mail surrender proceeds to you within seven
days of when we receive your request. (See "Other Policy Provisions - Payment of
Policy Benefits", Page .)

         A surrender may have Federal income tax consequences. (See "Tax
Treatment of Policy Benefits," Page ).

WITHDRAWAL OF CASH SURRENDER VALUE

         You may withdraw a portion of your Policy's Cash Surrender Value at any
time before the death of the Insured and, except for employee benefit plans,
after the first Policy Anniversary. The minimum amount which you may withdraw is
$500, except for employee benefit plans, where the minimum is $100. The maximum
Withdrawal is the Cash Surrender Value on the date of receipt of the Withdrawal
request, minus three times the Monthly Deduction for the most recent Monthly
Policy Date. A Withdrawal Charge will be deducted from the amount of the
Withdrawal. For a discussion of the Withdrawal Charge, see "Charges and
Deductions Withdrawal Charge" on Page .

         You may specify how you would like us to take a Withdrawal from the
Subaccounts of the Separate Account. If you do not so specify, we will take the
Withdrawal from the Subaccounts in proportion to the Accumulated Value in each
Subaccount. If the Accumulated Value in one or more Subaccounts is insufficient
to carry out your instructions, we will not process the Withdrawal until we
receive further instructions from you. You may take Withdrawals from the General
Account only after the Accumulated Value in the Separate Account has been
exhausted.

         The effect of a Withdrawal on the Death Benefit and Face Amount will
vary depending upon the Death Benefit Option in effect and whether the
Unadjusted Death Benefit is based on the applicable percentage of Accumulated
Value. (See "Death Benefit Options," Page .)

                                       36
<PAGE>   40

         Option A. The effect of a Withdrawal on the Face Amount and Unadjusted
Death Benefit under Option A can be described as follows:

                  If the Face Amount divided by the applicable percentage of
         Accumulated Value exceeds the Accumulated Value just after the
         Withdrawal, a Withdrawal will reduce the Face Amount and the Unadjusted
         Death Benefit by the lesser of such excess and the amount of the
         Withdrawal.

                  For the purposes of this illustration (and the following
         illustrations of Withdrawals), assume that the Attained Age of the
         Insured is under 40 and there is no indebtedness. The applicable
         percentage is 250% for an Insured with an Attained Age under 40.

                  Under Option A, a Policy with a Face Amount of $300,000 and an
         Accumulated Value of $30,000 will have an Unadjusted Death Benefit of
         $300,000. Assume that you take a Withdrawal of $10,000. The Withdrawal
         Charge will be $25 and the amount we pay you will be $9,975. The
         Withdrawal will reduce the Accumulated Value to $20,000 ($30,000 -
         $10,000) after the Withdrawal. The Face Amount divided by the
         applicable percentage is $120,000 ($300,000 / 2.50), which exceeds the
         Accumulated Value after the Withdrawal by $100,000 ($120,000 -
         $20,000). The lesser of this excess and the amount of the Withdrawal is
         $10,000, the amount of the Withdrawal. Therefore, the Unadjusted Death
         Benefit and Face Amount will be reduced by $10,000 to $290,000.

                  If the Face Amount divided by the applicable percentage of
         Accumulated Value does not exceed the Accumulated Value just after the
         Withdrawal, then the Face Amount is not reduced. The Unadjusted Death
         Benefit will be reduced by an amount equal to the reduction in
         Accumulated Value times the applicable percentage (or equivalently, the
         Unadjusted Death Benefit is equal to the new Accumulated Value times
         the applicable percentage).

                  Under Option A, a policy with a Face Amount of $300,000 and an
         Accumulated Value of $150,000 will have an Unadjusted Death Benefit of
         $375,000 ($150,000 x 2.50). Assume that you take a Withdrawal of
         $10,000. The Withdrawal Charge will be $25 and the amount we pay to you
         will be $9,975. The Withdrawal will reduce the Accumulated Value to
         $140,000 ($150,000 - $10,000). The Face Amount divided by the
         applicable percentage is $120,000, which does not exceed the
         Accumulated Value after the withdrawal. Therefore, the Face Amount
         stays at $300,000 and the Unadjusted Death Benefit is $350,000
         ($140,000 x 2.50).

         Option B. The Face Amount will never be decreased by a Withdrawal. A
Withdrawal will, however, always decrease the Death Benefit.

                  If the Unadjusted Death Benefit equals the Face Amount plus
         the Accumulated Value, a Withdrawal will reduce the Accumulated Value
         by the amount of the Withdrawal and thus the Unadjusted Death Benefit
         will also be reduced by the amount of the Withdrawal.

                  Under Option B, a Policy with a Face Amount of $300,000 and an
         Accumulated Value of $90,000 will have an Unadjusted Death Benefit of
         $390,000 ($300,000 + $90,000). Assume you take a Withdrawal of $20,000.
         The Withdrawal Charge will be $25 and the amount we pay to you will be
         $19,975. The Withdrawal will reduce the Accumulated Value to $70,000
         ($90,000 - $20,000) and the Unadjusted Death Benefit to $370,000
         ($300,000 + $70,000). The Face Amount is unchanged.

                  If the Unadjusted Death Benefit immediately prior to the
         Withdrawal is based on the applicable percentage of Accumulated Value,
         the Unadjusted Death Benefit will be reduced to equal the greater of
         (a) the Face Amount plus the Accumulated Value after deducting the
         amount of the Withdrawal and Withdrawal Charge and (b) the applicable
         percentage of Accumulated Value after deducting the amount of the
         Withdrawal.

                                       37
<PAGE>   41

                  Under Option B, a Policy with a Face Amount of $300,000 and an
         Accumulated Value of $210,000 will have an Unadjusted Death Benefit of
         $525,000 ($210,000 X 2.5). Assume you take a Withdrawal of $60,000. The
         Withdrawal Charge will be $25 and the amount we pay to you will be
         $59,975. The Withdrawal will reduce the Accumulated Value to $150,000
         ($210,000 - $60,000), and the Unadjusted Death Benefit to the greater
         of (a) the Face Amount plus the Accumulated Value, or $450,000
         ($300,000 + $150,000) and (b) the Unadjusted Death Benefit based on the
         applicable percentage of the Accumulated Value, or $375,000 ($150,000 X
         2.50). Therefore, the Unadjusted Death Benefit will be $450,000. The
         Face Amount is unchanged.

         Any decrease in Face Amount due to a Withdrawal will first reduce the
most recent increase in Face Amount, then the most recent increases,
successively, and lastly, the Initial Face Amount.

         Because a Withdrawal can affect the Face Amount and the Unadjusted
Death Benefit as described above, a Withdrawal may also affect the Net Amount at
Risk which is used to calculate the Cost of Insurance Charge under the Policy.
(See "Cost of Insurance Charge," Page .) Since a Withdrawal reduces the
Accumulated Value, the Cash Surrender Value of the Policy is reduced, thereby
increasing the likelihood that the Policy will lapse. (See "Policy Lapse," Page
 .) A request for Withdrawal may not be allowed if such Withdrawal would reduce
the Face Amount below the Minimum Face Amount for the Policy. Also, if a
Withdrawal would result in cumulative premiums exceeding the maximum premium
limitations applicable under the Code for life insurance, we will not allow the
Withdrawal.

        You may request a Withdrawal only by sending a signed written request to
us at our Home Office. You may not request a Withdrawal over the telephone. We
will ordinarily pay a Withdrawal within seven days of receiving at our Home
Office a valid Withdrawal request.

         A Withdrawal of Cash Surrender Value may have Federal income tax
consequences. (See "Tax Treatment of Policy Benefits," Page .)

FREE-LOOK PRIVILEGE

   
         The Policy provides for a "free-look" period, during which you may
cancel the Policy and receive a refund equal to the premiums paid on the Policy.
This free-look period ends on the latest of:
    

         (a) 45 days after Part A of the application for the Policy is signed

         (b) 10 days after you receive the Policy

         (c) 10 days after we mail the Notice of Withdrawal Right to you, or

         (d) any longer period provided by state law.

To cancel your Policy, you must return it to us or to our agent within the free
look period with a written request for cancellation.

TELEPHONE TRANSACTION PRIVILEGE

   
         If you elect the telephone transaction privilege, either on the
application for the Policy or thereafter by written authorization, you may
effect changes in premium allocation, transfers, and loans of up to $25,000 by
providing instructions to us at our Home Office over the telephone. We may
suspend telephone transaction privileges at any time, for any reason, if we deem
such suspension to be in the best interests of Policy Owners. You may, on the
application or by a written authorization, authorize your National Life agent to
provide telephone instructions on your behalf.
    

         We will employ reasonable procedures to confirm that instructions we
receive by telephone are genuine. If we follow these procedures, we will not be
liable for any losses due to unauthorized or fraudulent instructions. We may be
liable for any such losses if we do not follow these reasonable procedures. The
procedures to be followed for telephone transfers will include one or more of
the following:


                                       38
<PAGE>   42

          -    requiring some form of personal identification prior to acting on
               instructions received by telephone

          -    providing written confirmation of the transaction, and

          -    making a tape recording of the instructions given by telephone.

OTHER TRANSFER RIGHTS

         Transfer Right for Policy. During the first two years following Policy
issue, you may, on one occasion, transfer the entire Accumulated Value in the
Separate Account to the General Account, without regard to any limits on
transfers or free transfers.

         Transfer Right for Change in Investment Policy. If the investment
policy of a Subaccount of the Separate Account is materially changed, you may
transfer the portion of the Accumulated Value in that Subaccount to another
Subaccount or to the General Account, without regard to any limits on transfers
or free transfers.

         Exchange Right for Connecticut Residents. For eighteen months after the
Date of Issue, Connecticut residents may exchange the Policy for any flexible
premium adjustable benefit life insurance policy offered for sale by us, the
benefits of which policy do not vary with the investment performance of a
separate account. Evidence of insurability will not be required to effect this
exchange.

AVAILABLE AUTOMATED FUND MANAGEMENT FEATURES

         We currently offer, at no charge to you, two automated fund management
features. Only one of these features may be active for any single Policy at any
time. We are not legally obligated to continue to offer these features. Although
we have no current intention to do so, we may cease offering one or both these
features at any time, after providing 60 days prior written notice to all Owners
who are then utilizing the features being discontinued

         Dollar Cost Averaging. This feature permits you to automatically
transfer funds from the Money Market Subaccount to any other Subaccounts on a
monthly basis. You may elect Dollar Cost Averaging at issue by marking the
appropriate box on the initial application, and completing the appropriate
instructions. You may also begin a Dollar Cost Averaging program after issue by
filling out similar information on a change request form and sending it to us at
our Home Office.

         If you elect this feature, we will take the amount to be transferred
from the Money Market Subaccount and transfer it to the Subaccount or
Subaccounts designated to receive the funds, each month on the Monthly Policy
Date. If you elect Dollar Cost Averaging on your application for the Policy, it
will start with the Monthly Policy Date after the date that the reallocation of
the Accumulated Value out of the Money Market Subaccount and into the other
Subaccounts occurs. If you begin a Dollar Cost Averaging program after the free
look period is over, it will start on the next Monthly Policy Date. Dollar Cost
Averaging will continue until the amount in the Money Market Subaccount is
depleted. The minimum monthly transfer by Dollar Cost Averaging is $100, except
for the transfer which reduces the amount in the Money Market Subaccount to
zero. You may discontinue Dollar Cost Averaging at any time by sending an
appropriate change request form to the Home Office. You may not use the dollar
cost averaging feature to transfer Accumulated Value to the General Account.

   
         Dollar Cost Averaging allows you to move funds into the various
investment types on a more gradual and systematic basis than the frequency on
which you pay premiums. The periodic investment of the same amount will result
in higher numbers of units being purchased when unit prices are lower, and lower
numbers of units being purchased when unit prices are higher.  This technique
will not, however, assure a profit or protect against a loss in declining
markets. Moreover, for the dollar cost averaging technique to be effective,
amounts should be available for allocation from the Money Market Subaccount
through periods of low price levels as well as higher price levels.
    

                                       39
<PAGE>   43

         Portfolio Rebalancing. This feature permits you to automatically
rebalance the value in the Subaccounts on a semi-annual basis, based on your
premium allocation percentages in effect at the time of the rebalancing. You may
elect it at issue by marking the appropriate box on the application, or, after
issue, by completing a change request form and sending it to our Home Office.

         In Policies utilizing Portfolio Rebalancing from the Date of Issue, an
automatic transfer will take place which causes the percentages of the current
values in each Subaccount to match the current premium allocation percentages,
starting with the Monthly Policy Date six months after the Date of Issue, and
then on each Monthly Policy Date six months thereafter. Policies electing
Portfolio Rebalancing after issue will have the first automated transfer occur
as of the Monthly Policy Date on or next following the date we receive the
election at our Home Office, and subsequent rebalancing transfers will occur
every six months from that date. You may discontinue Portfolio Rebalancing at
any time by submitting an appropriate change request form to us at our Home
Office.

         If you change your Policy's premium allocation percentages, Portfolio
Rebalancing will automatically be discontinued unless you specifically direct
otherwise.

         Portfolio Rebalancing will result in periodic transfers out of
Subaccounts that have had relatively favorable investment performance in
relation to the other Subaccounts to which a Policy allocates premiums, and into
Subaccounts which have had relatively unfavorable investment performance in
relation to the other Subaccounts to which the Policy allocates premiums.


POLICY RIGHTS UNDER CERTAIN PLANS

         Policies may be purchased in connection with a plan sponsored by an
employer. In such cases, all rights under the Policy rest with the Policy Owner,
which may be the employer or other obligor under the plan, and benefits
available to participants under the plan will be governed solely by the
provisions of the plan. Accordingly, some of the options and elections under the
Policy may not be available to participants under the provisions of the plan. In
such cases, participants should contact their employers for information
regarding the specifics of the plan.


                               THE GENERAL ACCOUNT


         You may allocate some or all of your Net Premiums, and transfer some or
all of the Accumulated Value of your Policy to our General Account. We credit
interest on Net Premiums and Accumulated Value allocated to the General Account
at rates we declare. These rates will not be less than 4%. The principal, after
deductions, is also guaranteed. The General Account supports National Life 's
insurance and annuity obligations. All assets in the General Account are subject
to National Life's general liabilities from business operations.

         The General Account has not, and is not required to be, registered with
the SEC under the Securities Act of 1933. The General Account has not been
registered as an investment company under the Investment Company Act of 1940.
Therefore, the General Account and the interests therein are generally not
subject to regulation under the 1933 Act or the 1940 Act. The disclosures
relating to this account which are included in this Prospectus are for your
information and have not been reviewed by the SEC. However, such disclosures may
be subject to certain generally applicable provisions of the Federal securities
laws relating to the accuracy and completeness of statements made in

  MINIMUM GUARANTEED AND CURRENT INTEREST RATES

                                       40
<PAGE>   44

   
         The Accumulated Value not held as Collateral in the General Account is
guaranteed to accumulate at a minimum effective annual interest rate of 4%. We
may credit the non-loaned Accumulated Value in the General Account with current
rates in excess of the minimum guarantee, but we are not obligated to do so. We
have no specific formula for determining current interest rates. Since we
anticipate changing the current interest rate from time to time, in our sole
discretion, allocations to the General Account made at different times are
likely to be credited with different current interest rates. We will declare an
interest rate each month to apply to amounts allocated or transferred to the
General Account in that month. The rate declared on such amounts will remain in
effect for twelve months. At the end of the 12-month period, we may declare a
new current interest rate on such amounts and accrued interest thereon (which
may be a different current interest rate than the current interest rate on new
allocations to the General Account on that date). We will determine any interest
credited on the amounts in the General Account in excess of the minimum
guaranteed rate of 4% per year in our sole discretion. You assume the risk that
interest credited may not exceed the guaranteed minimum rate. Amounts allocated
to the General Account will not share in the investment performance of our
General Account.
    

   
         Amounts deducted from the non-loaned Accumulated Value in the General
Account for Withdrawals, Policy loans, transfers to the Separate Account,
Monthly Deductions or other charges are, for the purpose of crediting interest,
accounted for on a last in, first out ("LIFO") method.
    

         We may change the method of crediting interest from time to time,
provided that such changes do not have the effect of reducing the guaranteed
rate of interest below 4% per annum or shortening the period for which the
interest rate applies to less than 12 months.

         Bonus Interest. We currently intend to credit interest on non-loaned
Accumulated Value in the General Account for Policies in Policy Year 11 and
thereafter at rates which are 0.50% per annum higher than those that apply to
Policies still in their first ten Policy Years. This bonus is not guaranteed,
however, except as required by the state of issue. We may in our sole
discretion, upon prior notice to Owners, decide not to credit the bonus.

         Calculation of Non-loaned Accumulated Value in the General Account. The
non-loaned Accumulated Value in the General Account at any time is equal to
amounts allocated and transferred to it plus interest credited to it, minus
amounts deducted, transferred or withdrawn from it.

TRANSFERS FROM GENERAL ACCOUNT

         We allow only one transfer in each Policy Year from the amount of
non-loaned Accumulated Value in the General Account to any or all of the
Subaccounts of the Separate Account. The amount you transfer from the General
Account may not exceed the greater of 25% of the value of the non-loaned
Accumulated Value in such account at the time of transfer, or $1000. We will
make the transfer as of the Valuation Day we receive your written or telephone
request at our Home Office.

                             OTHER POLICY PROVISIONS

         Indefinite Policy Duration. The Policy can remain in force indefinitely
(in Texas and Maryland, however, the Policy matures at Attained Age 99 at which
time we will pay the Cash Surrender Value to you in one sum unless you have
chosen a Payment Option, and the Policy will terminate). However, for a Policy
to remain in force after the Insured reaches Attained Age 99, if the Face Amount
is greater than the Accumulated Value, the Face Amount will automatically be
decreased to the current Accumulated Value. Also, at Attained Age 99 Option B
automatically becomes Option A. No premium payments are allowed after Attained
Age 99, although loan repayments are allowed. The tax treatment of a Policy's
Accumulated Value after Age 100 is unclear, and you may wish to discuss this
treatment with a tax advisor.

         Payment of Policy Benefits. You may decide the form in which we pay
Death Benefit proceeds. During the Insured's lifetime, you may arrange for the
Death Benefit to be paid in a lump sum or under a

                                       41
<PAGE>   45
Settlement Option. These choices are also available upon surrender of the Policy
for its Cash Surrender Value. If you do not make an election, payment will be
made in a lump sum. The Beneficiary may also arrange for payment of the Death
Benefit in a lump sum or under a Settlement Option. If paid in a lump sum, we
will ordinarily pay the Death Benefit to the Beneficiary within seven days after
we receive proof of the Insured's death at our Home Office, and all other
requirements are satisfied. If paid under a Settlement Option, we will apply the
Death Benefit to the Settlement Option within seven days after we receive proof
of the Insured's death at our Home Office, and all other requirements are
satisfied.

         We will pay interest on the Death Benefit from the date of death until
payment is made. The interest rate will be the highest of (a) 4% per annum, (b)
any higher rate we declare, or (c) any higher rate required by law.

         We will normally pay proceeds of a surrender, Withdrawal, or Policy
loan within seven days of when we receive your written request at our Home
Office in a form satisfactory to us.

         We will generally determine the amount of a payment on the Valuation
Day we receive all required documents. However, we may defer the determination
or payment of such amounts if the date for determining such amounts falls within
any period during which:

         (1)  the disposal or valuation of a Subaccount's assets is not
              reasonably practicable because the New York Stock Exchange is
              closed or conditions are such that, under the SEC's rules and
              regulations, trading is restricted or an emergency is deemed to
              exist; or

         (2)  the SEC by order permits postponement of such actions for the
              protection of our policyholders.

         We also may defer the determination or payment of amounts from the
General Account for up to six months.

         Transactions will not be processed on the following days: New Year's
Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving, the day after Thanksgiving and Christmas Day. In addition, Premium
Payments will not be allocated and transactions will not be effected to the
Money Market Subaccount on Columbus Day and Veterans Day.

         We may postpone any payment under the Policy derived from an amount
paid by check or draft until we are satisfied that the check or draft has been
paid by the bank upon which it was drawn.

         The Contract. The Policy and the application are the entire contract.
Only statements made in the application can be used to void the Policy or deny a
claim. The statements are considered representations and not warranties. Only
one of National Life's duly authorized officers or registrars can agree to
change or waive any provisions of the Policy, and only in writing. As a result
of differences in applicable state laws, certain provisions of the Policy may
vary from state to state.

         Ownership. The Owner is the Insured unless a different Owner is named
in the application or thereafter changed. While the Insured is living, the Owner
is entitled to exercise any of the rights stated in the Policy or otherwise
granted by us. If the Insured and Owner are not the same, and the Owner dies
before the Insured, these rights will vest in the estate of the Owner, unless
otherwise provided.

         Beneficiary. You designate the Beneficiary in the application for the
Policy. You may change the Beneficiary during the Insured's lifetime by sending
us a written notice. The interest of any Beneficiary who dies before the Insured
shall vest in you unless you otherwise provide.

         Change of Owner and Beneficiary. As long as the Policy is in force, you
may change the Owner or Beneficiary by sending us an acceptable written request.
The change will take effect as of the date the request is signed, whether or not
the Insured is living when we receive the request. We will not be responsible
for any payment made or action taken before we receive the written request.


                                       42
<PAGE>   46
         Split Dollar Arrangements. You may enter into a Split Dollar
Arrangement among the Owners or other persons under which the payment of
premiums and the right to receive the benefits under the Policy (i.e., Cash
Surrender Value or Death Benefit) are split between the parties. There are
different ways of allocating such rights.

         For example, an employer and employee might agree that under a Policy
on the life of the employee, the employer will pay the premiums and will have
the right to receive the Cash Surrender Value. The employee may designate the
Beneficiary to receive any Death Benefit in excess of the Cash Surrender Value.
If the employee dies while such an arrangement is in effect, the employer would
receive from the Death Benefit the amount which the employer would have been
entitled to receive upon surrender of the Policy and the employee's Beneficiary
would receive the balance of the proceeds.

         No transfer of Policy rights pursuant to a Split Dollar Arrangement
will be binding on us unless it is in writing and received by us. We do not
assess any specific charge for Split Dollar Arrangements.

         The parties who elect to enter into a Split Dollar Arrangement should
consult their own tax advisers regarding the tax consequences of such an
arrangement.

         Assignments. You may assign any and all your rights under the Policy.
We are not bound by an assignment unless it is in writing and we receive it at
our Home Office. We assume no responsibility for determining whether an
assignment is valid, or the extent of the assignee's interest. All assignments
will be subject to any Policy loan. The interest of any Beneficiary or other
person will be subordinate to any assignment. A payee who is not also the Owner
may not assign or encumber Policy benefits, and to the extent permitted by
applicable law, such benefits are not subject to any legal process for the
payment of any claim against the payee.

         Misstatement of Age and Sex. If the age or sex of the Insured at the
Date of Issue has been misstated in the application, we will adjust the
Accumulated Value of the Policy to be the amount that it would have been had the
Cost of Insurance Charges deducted been based on the correct age and sex, or as
otherwise required by state law. The adjustment will take place on the Monthly
Policy Date on or after the date on which we have proof to our satisfaction of
the misstatement. If the Insured has died, we will adjust the Accumulated Value
as of the last Monthly Policy Date prior to the Insured's death; however, if the
Accumulated Value is insufficient for that adjustment, the amount of the
Unadjusted Death Benefit will also be adjusted.

         Suicide. If the Insured dies by suicide, while sane or insane, within
two years from the Date of Issue of the Policy (except where state law requires
a shorter period), or within two years of the effective date of a reinstatement
(unless otherwise required by state law), our liability is limited to the
payment to the Beneficiary of a sum equal to the premiums paid less any Policy
loan and accrued interest and any Withdrawals (since the date of reinstatement,
in the case of a suicide within two years of the effective date of a
reinstatement), or other reduced amount provided by state law.

         If the Insured commits suicide within two years (or shorter period
required by state law) from the effective date of any Policy change which
increases the Unadjusted Death Benefit and for which an application is required,
the amount which we will pay with respect to the increase will be the Cost of
Insurance Charges previously made for such increase (unless otherwise required
by state law).

         Incontestability. The Policy will be incontestable after it has been in
force during the Insured's lifetime for two years from the Date of Issue (or
such other date as required by state law). Similar incontestability will apply
to an increase in Face Amount or reinstatement after it has been in force during
the Insured's lifetime for two years from its effective date.

         Before such times, however, we may contest the validity of the Policy
(or changes) based on material misstatements in the initial or any subsequent
application.


                                       43
<PAGE>   47
         Arbitration. Except where otherwise required by state law, the Policy
provides that any controversy under the Policy shall be settled by arbitration
in the state of residence of the Owner, in accordance with the rules of the
American Arbitration Association or any similar rules to which the parties
agree. Any award rendered through arbitration will be final on all parties, and
the award may be enforced in court.

         The purpose of the arbitration is to provide an alternative dispute
resolution mechanism for investors that may be more efficient and less costly
than court litigation. You should be aware, however, that arbitration is, as
noted above, final and binding on all parties, and that the right to seek
remedies in court is waived, including the right to jury trial. Pre-arbitration
discovery is generally more limited than and different from court discovery
procedures, and the arbitrator's award is not required to include factual
findings or legal reasoning. Any party's right to appeal or to seek modification
of rulings by the arbitrators is strictly limited.

   
         Dividends. The Policy is participating; however, no dividends are
expected to be paid on the Policy. If dividends are ever declared, they will be
paid in cash. At the time of the insured person's death, the Death Benefit will
be increased by dividends payable, if any.
    

         Correspondence. All correspondence to you is deemed to have been sent
to you if mailed to you at your last address known to us.

         Settlement Options. In lieu of a single sum payment on death or
surrender, you may elect to apply the Death Benefit under any one of the
fixed-benefit Settlement Options provided in the Policy. The options are
described below.

   
         Payment of Interest Only. We will pay interest at a rate of 3.5% per
year on the amount of the proceeds retained by us. Upon the earlier of the
payee's death or the end of a chosen period, the proceeds retained will be paid
to the Payee or his or her estate.
    

         Payments for a Stated Time. We will make equal monthly payments, based
on an interest rate of 3.5% per annum, for the number of years you select.

         Payments for Life. We will make equal monthly payments, based on an
interest rate of 3.5% per annum, for a guaranteed period and thereafter during
the life of a chosen person. You may elect guaranteed payment periods for 0, 10,
15, or 20 years, or for a refund period, at the end of which the total payments
will equal the proceeds placed under the option.

         Payments of a Stated Amount. We will make equal monthly payments until
the proceeds, with interest at 3.5% per year on the unpaid balance, have been
paid in full. The total payments in any year must be at least $10 per month for
each thousand dollars of proceeds placed under this option.

         Life Annuity. We will make equal monthly payments in the same manner as
in the above Payments for Life option except that the amount of each payment
will be the monthly income provided by our then current settlement rates on the
date the proceeds become payable. No additional interest will be paid.

         Joint and Two Thirds Annuity. We will make equal monthly payments,
based on an interest rate of 3.5% per year, while two chosen persons are both
living. Upon the death of either, two-thirds of the amount of those payments
will continue to be made during the life of the survivor. We may require proof
of the ages of the chosen persons.

         50% Survivor Annuity. We will make equal monthly payments, based on an
interest rate of 3.5% per year, during the lifetime of the chosen primary
person. Upon the death of the chosen primary person, 50% of the amount of those
payments will continue to be made during the lifetime of the secondary chosen
person. We may require proof of the ages of the chosen persons.

   
         We may pay interest in excess of the stated amounts under the first
four options listed above, but not the last three. Under the first two, and
fourth options above, the Payee has the right to change options or to withdraw
all or part of the remaining proceeds.  For additional information concerning
the payment options, see the Policy.

                                OPTIONAL BENEFITS


         You may include the following benefits, which are subject to the
restrictions and limitations set forth in the applicable Policy Riders, in your
Policy at your option. Election of any of these optional benefits involves an
additional cost.

         Waiver of Monthly Deductions. If you elect the Waiver of Monthly
Deductions Rider, we will waive Monthly Deductions against the Policy if the
Insured becomes totally disabled, before age 65 and for at least 120 days. If
total disability occurs after age 60 and before age 65, then we will waive
Monthly Deductions only until the Insured reaches Attained Age 65, or for a
period of two years, if longer. The monthly cost of this Rider is based on
sex-distinct rates (except for Policies issued in states which require "unisex"
policies or in conjunction with employee benefit plans, where the cost of this
Rider will not vary by sex) multiplied by the Monthly Deduction on the Policy.
We will add this cost to the Monthly Deduction on the Policy.

         Accidental Death Benefit. The Accidental Death Rider provides for an
increased Death Benefit in the event that the Insured dies in an accident. If
you elect this Rider, we will add the monthly cost of this Rider to the Monthly
Deduction on the Policy.

         Guaranteed Insurability Option. This Rider permits you to increase the
Face Amount of the Policy, within certain limits, without being required to
submit satisfactory proof of insurability at the time of the request for the
increase. Again, if you elect this Rider, we will add the monthly cost of this
Rider to the Monthly Deduction on the Policy.

   
         Guaranteed Death Benefit. If you choose this Rider, we will guarantee
that the Policy will not lapse prior to the Insured's Attained Age 70, or 20
years from the Date of Issue of the Policy, if longer, regardless of the
Policy's investment performance. To keep this Rider in force, you must pay
cumulative premiums greater than the Minimum Guarantee Premium from the Date of
Issue. The Minimum Guarantee Premium for Policies with the Guaranteed Death
Benefit Rider will be higher than for those without the Guaranteed Death Benefit
Rider, all other things being equal.  We will test the Policy monthly for this
qualification, and if not met, we will send you a notice, and you will have 61
days from the date we mailed the notice to pay a premium sufficient to keep the
Rider in force. The premium required will be the Minimum Guarantee Premium from
the Date of Issue, plus two times the Minimum Monthly Premium, minus premiums
previously paid. The Rider will be cancelled if a sufficient premium is not paid
during that 61-day period. If cancelled, the Rider cannot be reinstated
    

         The cost of the Guaranteed Death Benefit Rider is $0.01 per thousand of
Face Amount per month. This Rider is available only at issue, and only for Issue
Ages 0-65.

         If while the Guaranteed Death Benefit Rider is in force, the
Accumulated Value of the Policy is not sufficient to cover the Monthly
Deductions, Monthly Deductions will be made until the Accumulated Value of the
Policy is exhausted, and will thereafter be deferred, and collected at such time
as the Policy has positive Accumulated Value.

         If you increase the Face Amount of a Policy subject to the Guaranteed
Death Benefit Rider, the Rider's guarantee will extend to the increased Face
Amount. This will result in increased Minimum Guarantee Premiums.

         If you have elected both the Waiver of Monthly Deductions Rider and the
Guaranteed Death Benefit Rider, and Monthly Deductions are waived because of
total disability, then we will also waive the Minimum Guarantee Premiums
required to keep the Guaranteed Death Benefit Rider in force during the period
that Monthly Deductions are being waived.

   
         If you wish to keep this Rider in force, you must limit Withdrawals and
Policy loans to the excess of premiums paid over the sum of the Minimum Monthly
Premiums in effect since the Date of Issue. If you take a Policy loan or
Withdrawal for an
    


                                       45
<PAGE>   49
amount greater than such excess, the Guaranteed Death Benefit Rider will enter a
61-day lapse-pending notification period, and will be cancelled if you do not
pay a sufficient premium.

 THE GUARANTEED DEATH BENEFIT RIDER IS NOT AVAILABLE IN TEXAS OR MASSACHUSETTS.

   
      Rider for Disability Benefit - Payment of Mission Costs. If you are buying
your policy through a registered representative who is an agent of Beneficial
Life Insurance Company, you may at your option include in your policy the Rider
for Disability - Payment of Mission Costs. Election of this benefit involves
additional cost.
    

   
      This Rider, which is subject to the restrictions and limitations set forth
in the Rider, provides a monthly benefit equal to the expenses of any dependent
children (under age 30) participating in voluntary mission service, up to a
maximum of $375 per month per child, while the Insured is totally disabled. The
maximum benefit duration is 24 months for each child. The maximum benefit will
be adjusted for inflation at an annual rate of 3%.
    

   
      Benefits will be paid when the insured has been continuously disabled for
a period of six months due to disabilities occurring prior to age 65. After six
months of continuous disability, benefit payments are retroactive to the
beginning of the period. Coverage ceases at age 65. For Insureds disabled prior
to age 65, benefit eligibility continues until disability ends.
    

   
      The monthly cost of this Rider is level, and varies by the age at issue
and the sex of the insured (except for Policies issued in states which require
"unisex" Policies, where the cost of this Rider will not vary by sex). The cost
of the Rider does not vary by the number of dependent children. Depending on the
age and sex of the Insured, the monthly cost of the Rider will range from $1.65
to $4.25. The monthly cost of this Rider will be added to the Monthly Deduction
on the Policy.
    

   
      Accelerated Benefits Rider. This Rider pays a reduced benefit prior to the
death of the Insured, in certain circumstances where a terminal or chronic
illness creates a need for access to the death benefit. This Rider is not
available in all states, and its terms may vary by state. There is no cost for
this Rider. It can be included in a Policy at issue, or can be added after
issue, for Insureds ages 0-85. The maximum amount payable under the Rider is
$500,000. An Insured who has a chronic illness, as defined in the Rider, at the
time the Rider is issued, may not receive benefits under the Rider for five
years after its issue.
    



                        FEDERAL INCOME TAX CONSIDERATIONS


INTRODUCTION

         The following summary provides a general description of the Federal
income tax considerations associated with the Policy and does not purport to be
complete or to cover all tax situations. This discussion is not intended as tax
advice. Counsel or other competent tax advisors should be consulted for more
complete information. This discussion is based upon understanding of the present
Federal income tax laws. No representation is made as to the likelihood of
continuation of the present Federal income tax laws or as to how they may be
interpreted by the Internal Revenue Service.

TAX STATUS OF THE POLICY

         In order to qualify as a life insurance contract for Federal income tax
purposes and to receive the tax treatment normally accorded life insurance
contracts under Federal tax law, a life insurance policy must satisfy certain
requirements which are set forth in the Internal Revenue Code. Guidance as to
how these requirements are to be applied is limited. Nevertheless, National Life
believes that a Policy issued on the basis of a standard rate class should
satisfy the applicable requirements. There is less guidance, however, with
respect to a policy issued on a substandard basis (i.e., a rate class involving
higher than standard mortality risk) and it is not clear whether such a policy
will in all cases satisfy the applicable requirements, particularly if the Owner
pays the full amount of premiums permitted under the Policy. Nevertheless,
National Life believes it reasonable to conclude that such a Policy should be
treated as a life insurance contract for Federal income tax purposes. If it is
subsequently determined that a Policy does not satisfy the applicable
requirements, National Life may take appropriate steps to bring the policy into
compliance with such requirements and National Life reserves the right to modify
the policy as necessary in order to do so.

         In certain circumstances, owners of variable life insurance policies
have been considered for Federal income tax purposes to be the owners of the
assets of separate accounts supporting their contracts due to their ability to
exercise investment control over those assets. Where this is the case, the
policyowners have been currently taxed on income and gains attributable to
separate account assets. There is little guidance in this area, and some
features of the policy, such as the flexibility of Policy Owners to allocate
premium payments and Accumulated Values, have not been explicitly addressed in
published rulings. While National Life believes that the policy does not give
Policy Owners investment control over Separate Account assets, we reserve the
right to modify the policy as necessary to prevent the Policy Owner from being
treated as the owner of the Separate Account assets supporting the Policy.

         In addition, the Code requires that the investments of the Separate
Account be "adequately diversified" in order for the policy to be treated as a
life insurance contract for Federal income tax purposes. It is intended that the
Separate Account, through the Funds, will satisfy these diversification
requirements.

         The following discussion assumes that the Policy will qualify as a life
insurance contract for Federal income tax purposes.

                                       46

TAX TREATMENT OF POLICY BENEFITS

         In General. National Life believes that the death benefit under a
Policy should be excludible from the gross income of the beneficiary. Federal,
state and local estate, inheritance, transfer, and other tax consequences of
ownership or receipt of Policy proceeds depend on the circumstances of each
Policy Owner or beneficiary. A tax advisor should be consulted on these
consequences.

         Generally, a Policy Owner will not be deemed to be in constructive
receipt of the Accumulated Value until there is a distribution. When
distributions from a Policy occur, or when loans are taken out from or secured
by a Policy, the tax consequences depend on whether the Policy is classified as
a "Modified Endowment Contract."

         Modified Endowment Contracts. Under the Internal Revenue Code, certain
life insurance contracts are classified as "Modified Endowment Contracts," with
less favorable tax treatment than other life insurance contracts. Due to the
flexibility of the Policy as to premium payments and benefits, the individual
circumstances of each Policy will determine whether it is classified as a
Modified Endowment Contract. The rules are too complex to be summarized here,
but generally depend on the amount of premium payments made during the first
seven policy years. Certain changes in a policy after it is issued could also
cause it to be classified as a Modified Endowment Contract. A current or
prospective Policy Owner should consult with a competent advisor to determine
whether a policy transaction will cause the Policy to be classified as a
Modified Endowment Contract.

         Distributions Other Than Death Benefits from Modified Endowment
Contracts. Policies classified as Modified Endowment Contracts are subject to
the following tax rules:

         (1)      All distributions other than death benefits from a Modified
                  Endowment Contract, including distributions upon surrender and
                  withdrawals, will be treated first as distributions of gain
                  taxable as ordinary income and as tax-free recovery of the
                  Policy Owner's investment in the Policy only after all gain
                  has been distributed.

         (2)      Loans taken from or secured by a Policy classified as a
                  Modified Endowment Contract are treated as distributions and
                  taxed accordingly.

         (3)      A 10 percent additional income tax is imposed on the amount
                  subject to tax except where the distribution or loan is made
                  when the Policy Owner has attained age 59-1/2 or is disabled,
                  or where the distribution is part of a series of substantially
                  equal periodic payments for the life (or life expectancy) of
                  the Policy Owner or the joint lives (or joint life
                  expectancies) of the Policy Owner and the Policy Owner's
                  beneficiary or designated beneficiary.

         Distributions Other Than Death Benefits from Policies that are not
Modified Endowment Contracts. Distributions other than death benefits from a
Policy that is not classified as a Modified Endowment Contract are generally
treated first as a recovery of the Policy Owner's investment in the policy and
only after the recovery of all investment in the policy as taxable income.
However, certain distributions which must be made in order to enable the Policy
to continue to qualify as a life insurance contract for Federal income tax
purposes if policy benefits are reduced during the first 15 policy years may be
treated in whole or in part as ordinary income subject to tax.

         Loans from or secured by a Policy that is not classified as a Modified
Endowment Contract are generally not treated as distributions. However, the tax
consequences associated with preferred Policy loans is less clear and a tax
adviser should be consulted about such loans.

         Finally, neither distributions from nor loans from or secured by a
Policy that is not a Modified Endowment Contract are subject to the 10 percent
additional income tax.

         Investment in the Policy. Your investment in the Policy is generally
your aggregate premium payments. When a distribution is taken from the Policy,
your investment in the Policy is reduced by the amount of the distribution that
is tax-free.

         Policy Loan Interest. In general, interest paid on any loan under a
Policy will not be deductible.

         Multiple Policies. All Modified Endowment Contracts that are issued by
National Life (or its affiliates) to the same Policy Owner during any calendar
year are treated as one Modified Endowment Contract for purposes of determining
the amount includible in the Policy Owner's income when a taxable distribution
occurs.

         Business Uses of the Policy. Businesses can use the Policy in various
arrangements, including nonqualified deferred compensation or salary continuance
plans, split dollar insurance plans, executive bonus plans, tax exempt and
nonexempt welfare benefit plans, retiree medical benefit plans and others. The
tax consequences of such plans may vary depending on the particular facts and
circumstances. If you are purchasing the Policy for any arrangement the value of
which depends in part on its tax consequences, you should consult a qualified
tax adviser. In recent years, moreover, Congress has adopted new rules relating
to life insurance owned by businesses. Any business contemplating the purchase
of a new Policy or a change in an existing Policy should consult a tax adviser.

         Continuation Beyond Age 100. The tax consequences of continuing the
Policy beyond the insured's 100th year are unclear. You should consult a tax
adviser if you intend to keep the Policy in force beyond the insured's 100th
year.

SPECIAL RULES FOR EMPLOYEE BENEFIT PLANS

         If a trustee under a pension or profit-sharing plan, or similar
deferred compensation arrangement, owns a Policy, the Federal and state income
and estate tax consequences could differ. A tax adviser should be consulted with
respect to such consequences. Policies owned under these types of plans may also
be subject to restrictions under the Employee Retirement Income Security Act of
1974 ("ERISA"). You should consult a qualified adviser regarding ERISA.

         The amounts of life insurance that may be purchased on behalf of a
participant in a pension or profit-sharing plan are limited.

         The current cost of insurance for the net amount at risk is treated as
a "current fringe benefit" and must be included annually in the plan
participant's gross income. We report this cost (generally referred to as the
"P.S. 58" cost) to the participant annually.

         If the plan participant dies while covered by the plan and the Policy
proceeds are paid to the participant's beneficiary, then the excess of the death
benefit over the Accumulated Value is not taxable. However, the Accumulated
Value will generally be taxable to the extent it exceeds the participant's cost
basis in the Policy.

POSSIBLE TAX LAW CHANGES

         Although the likelihood of legislative changes is uncertain, there is
always the possibility that the tax treatment of the policy could change by
legislation or otherwise. Consult a tax adviser with respect to legislative
developments and their effect on the Policy.

POSSIBLE CHARGES FOR NATIONAL LIFE'S TAXES

   
         At the present time, National Life makes no charge for any Federal,
state or local taxes (other than the charge for state premium taxes and the DAC
tax) that may be attributable to the Subaccounts or to the policies. National
Life reserves the right to charge the Subaccounts for any future taxes or
economic burden National Life may incur.
    


           POLICIES ISSUED IN CONJUNCTION WITH EMPLOYEE BENEFIT PLANS


         Policies may be acquired in conjunction with employee benefit plans,
including the funding of qualified pension plans meeting the requirements of
Section 401 of the Code.

         For employee benefit plan Policies, the maximum cost of insurance rates
used to determine the monthly Cost of Insurance Charge are based on the
Commissioners' 1980 Standard Ordinary Mortality Tables NB and SB. Under these
Tables, mortality rates are the same for male and female Insureds of a
particular Attained Age and Rate Class. (See "Cost of Insurance Charge," Page .)

         Illustrations reflecting the premiums and charges for employee benefit
plan Policies will be provided upon request to purchasers of such Policies.

         There is no provision for misstatement of sex in the employee benefit
plan Policies. (See "Misstatement of Age and Sex," Page .) Also, the rates used
to determine the amount payable under a particular Settlement Option will be the
same for male and female Insureds. (See "Settlement Options," Page .)


              LEGAL DEVELOPMENTS REGARDING UNISEX ACTUARIAL TABLES


         In 1983, the United States Supreme Court held in Arizona Governing
Committee v. Norris that optional annuity benefits provided under an employee's
deferred compensation plan could not, under Title VII of the Civil Rights Act of
1964, vary between men and women on the basis of sex. In that case, the Court
applied its decision only to benefits derived from contributions made on or
after August 1, 1983. Subsequent decisions of lower federal courts indicate that
in other factual circumstances the Title VII prohibition of sex-distinct
benefits may apply at an earlier date. In addition, legislative, regulatory, or
decisional authority of some states may prohibit use of sex-distinct mortality
tables under certain circumstances. The Policies offered by this Prospectus,
other than Policies issued in states which require "unisex" policies (currently
Montana) and employee benefit plan Policies (see "Policies Issued in Conjunction
with Employee Benefit Plans," Page ) are based upon actuarial tables which
distinguish between men and women and, thus, the Policy provides different
benefits to men and women of the same age. Accordingly, employers and employee
organizations should consider, in consultation with legal counsel, the impact of
these authorities on any employment-related insurance or benefits program before
purchasing the Policy and in determining whether an employee benefit plan Policy
is appropriate.

                                  VOTING RIGHTS


         We will invest all of the assets held in the Subaccounts of the
Separate Account in shares of corresponding Portfolios of the Funds. The Funds
do not hold routine annual shareholders' meetings. Shareholders' meetings will
be called whenever each Fund believes that it is necessary to vote to elect the
Board of Directors of the Fund and to vote upon certain other matters that are
required to be approved or ratified by the shareholders of a mutual fund.

         We are the legal owner of Fund shares and as such have the right to
vote upon any matter that may be voted upon at a shareholders' meeting. However,
in accordance with the SEC's view of present applicable law, we will vote the
shares of the Funds at meetings of the shareholders of the appropriate Fund or
Portfolio in accordance with instructions of Policy Owners. We will vote Fund
shares held in each Subaccount of the Separate Account for which Owners do not
send timely instructions in the same proportion as those shares in that
Subaccount for which instructions are received.

         If you have a voting interest, we will send you proxy material and a
form for giving voting instructions. You may vote, by proxy or in person, only
as to the Portfolios that correspond to the Subaccounts in which your Policy
values are allocated. We will determine the number of shares held in each
Subaccount attributable to a Policy for which you may provide voting
instructions by dividing the Policy's Accumulated Value in that account by the
net asset value of one share of the corresponding Portfolio as of the record
date for the shareholder meeting. We will count fractional shares. For each
share of a Portfolio for which Owners have no interest, we will cast votes, for
or against any matter, in the same proportion as Owners provide voting
instructions.

         If required by state insurance officials, we may disregard voting
instructions if they would require shares to be voted so as to cause a change in
the investment objectives or policies of one or more of the Portfolios, or to
approve or disapprove an investment policy or investment adviser of one or more
of the Portfolios. In addition, we may disregard voting instructions in favor of
certain changes initiated by an Owner or the Fund's Board of Directors if our
disapproval of the change is reasonable and is based on a good faith
determination that the change would be contrary to state law or otherwise
inappropriate, considering the portfolio's objectives and purposes, and the
effect the change would have on us. If we disregard voting instructions, we will
advise you of that action and our reasons in the next semi-annual report to
Owners.

         Shares of the Funds are currently being offered to variable life
insurance and variable annuity separate accounts of life insurance companies
other than National Life that are not affiliated with National Life. National
Life understands that shares of these Funds also will be voted by such other
life insurance companies in accordance with instructions from their
policyholders invested in such separate accounts. This will dilute the effect of
your voting instructions.

                CHANGES IN APPLICABLE LAW, FUNDING AND OTHERWISE

         The voting rights described in this Prospectus are created under
applicable Federal securities laws. If changes in these laws or regulations
eliminate the necessity to solicit your voting instructions or restrict such
voting rights, we may proceed in accordance with these laws or regulations.

         We may also take the steps listed below, if we feel such an action is
reasonably necessary. In doing so we would comply with all applicable laws,
including approval of Owners, if so required:

         (1) to make changes in the form of the Separate Account, if in our
         judgment such changes would serve the interests of Owners or would be
         appropriate in carrying out the purposes of the Policies, for example:

                  (i) operating the Separate Account as a management company
                      under the 1940 Act

                                       50
<PAGE>   54
                  (ii) deregistering the Separate Account under the 1940 Act if
                       registration is no longer required

                  (iii) combining or substituting separate accounts

                  (iv) transferring the assets of the Separate Account to
                       another separate account or to the General Account

                  (v) making changes necessary to comply with, obtain or
                      continue any exemptions from the 1940 Act; or


                  (vi) making other technical changes in the Policy to conform
                       with any action described herein;

         (2) if in our judgment a Portfolio no longer suits the investment goals
             of the Policy, or if tax or marketing conditions so warrant, to
             substitute shares of another investment portfolio for shares of
             such Portfolio;

         (3) to eliminate, combine, or substitute Subaccounts and establish new
             Subaccounts, if in its judgment marketing needs, tax
             considerations, or investment conditions so warrant;

         (4) to transfer assets from a Subaccount to another Subaccount or
             separate account if the transfer in our judgment would best serve
             interests of Policy Owners or would be appropriate in carrying out
             the purposes of the Policies; and

         (5) to modify the provisions of the Policies to comply with applicable
             laws.

         We have reserved all rights in respect of our corporate name and any
part thereof, including without limitation the right to withdraw its use and to
grant its use to one or more other separate accounts and other entities.

         If your Policy has Accumulated Value in a Subaccount that is
eliminated, we will give you at least 30 days notice before the elimination, and
will request that you name the Subaccount or Subaccounts (or the General
Account) to which the Accumulated Value in that Subaccount should be
transferred. If you do not name a new Subaccount, then we will use the Money
Market Subaccount. In any case, if in the future we impose a transfer charge or
establish limits on the number of transfers or free transfers, no charge will be
made for this transfer, and it will not count toward any limit on transfers or
free transfers.

                            DISTRIBUTION OF POLICIES

         We sell Policies through agents who are licensed by state insurance
authorities to sell our variable life insurance policies, and who are also
registered representatives of Equity Services, Inc. ("ESI") or registered
representatives of broker/dealers who have Selling Agreements with ESI. ESI,
whose address is National Life Drive, Montpelier, Vermont 05604, is a registered
broker/dealer under the Securities Exchange Act of 1934 (the "1934 Act") and a
member of the National Association of Securities Dealers, Inc. (the "NASD"). ESI
is an indirect wholly-owned subsidiary of National Life, formed on October 7,
1968. ESI acts as the principal underwriter, as defined in the 1940 Act, of the
Policies, and for the Separate Account pursuant to an Underwriting Agreement to
which the Separate Account, ESI and National Life are parties.

         National Life has sought approval to sell the Policies in all states
and the District of Columbia. However, all approvals may not be obtained. The
Policies are offered and sold only in those states where their sale is lawful.

         The directors of ESI are Patrick E. Welch, Thomas H. MacLeay, Rodney A.
Buck, all of whose principal occupations are disclosed under "Directors and
Officers of National Life" above, and Joseph M. Rob, the Chairman, Chief
Executive Officer and President of ESI. ESI's other officers are:

         Lisa A. Pettrey          Secretary
         JoAnn K. Morissette      Assistant Secretary
</TABLE>

         The principal business address of all these individuals is National
Life Drive, Montpelier, Vermont 05604.

   
         We do the insurance underwriting , determine a proposed Insured's Rate
Class, and determine whether to accept or reject an application for a Policy. We
will refund any premiums paid if a Policy ultimately is not issued or will
refund the applicable amount if the Policy is returned under the free look
provision. 
    

   
         Agents who are ESI registered representatives are compensated for
sales of the Policies on a commission basis and with other forms of
compensation. During the first Policy Year, agent commissions will not be more
than 50% of the premiums paid up to a target amount (which is a function of
Face Amount, and which is used primarily to determine commission payments) and
3% of the premiums paid in excess of that amount. For Policy Years 2 through
10, the agent commissions will not be more than 4% of the premiums paid up to
the target amount, and 3% of premiums paid in excess of that amount. For Policy
year 11 and thereafter, agent commissions will be 1.5% of all premiums paid.
For premiums received in the year following an increase in Face Amount and
attributable to the increase, agent commissions will not be more than 48.5% up
to the target amount for the increase. Full time agents of National Life who
achieve specified annual sales goals may be eligible for compensation in
addition to the amounts stated above.
    

   
         Dealers other than ESI will receive gross dealer concessions during
the first Policy Year of 85% of the premiums paid up to the target amount and
4% of the premiums paid in excess of that amount. For Policy Years 2 through
10, the gross dealer concession will not be more than 4% of the premiums paid.
For Policy Year 11 and thereafter, the gross dealer concession will be 1.5% of

Face Amount and attributable to the increase, the gross dealer concession will
not be more than 50% up to the target amount for the increase.

                             PREPARING FOR YEAR 2000

<PAGE>   58
         Many computer systems were designed using only two digits to designate
years. These systems may not be able to distinguish the year 2000 from the year
1900. Like all financial services providers, we utilize computer systems that
may be effected by Year 2000 transition issues. We also rely on service
providers, including the Funds, that also may be affected. We have developed,
and are in the process of implementing, a Year 2000 transition plan, and are
confirming that our service providers are also so engaged. The resources that
are being devoted to this effort are substantial. It is difficult to predict
with precision whether the amount of resources ultimately devoted, or the
outcome of these efforts, will have any negative impact on us. However, as of
the date of this prospectus, it is not anticipated that you will experience
negative effects on your investment, or on the services provided in connection
with your Policy, as a result of Year 2000 transition implementation. We
currently anticipate that our computer systems will be Year 2000 compliant on or
about June 30, 1999, but there can be no assurance that we will be successful,
or that interaction with other service providers will not impair our services at
that time.

                                     EXPERTS

         The Financial Statements listed on Page F-1 have been included in this
Prospectus, in reliance on the reports of PricewaterhouseCoopers LLP,
independent accountants, given on the authority of that firm as experts in
accounting and auditing.

         Actuarial matters included in the Prospectus have been examined by
Elizabeth H. MacGowan, F.S.A. MAAA, Associate Actuary Product Development of
National Life.


                                  LEGAL MATTERS


         Sutherland, Asbill & Brennan LLP of Washington, D.C. has provided
advice on legal matters relating to certain aspects of Federal securities law
applicable to the issue and sale of the Policies. Matters of Vermont law
pertaining to the Policies, including National Life's right to issue the
Policies and its qualification to do so under applicable laws and regulations
issued thereunder, have been passed upon by Michele S. Gatto, Senior Vice
President and General Counsel of National Life.

         The Separate Account is not a party to any litigation. There are no
material legal proceedings involving National Life which are likely to have a
material adverse effect upon the Separate Account or upon the ability of
National Life to meet its obligations under the Policies. ESI is not engaged in
any litigation of any material nature.

         In recent years life insurance companies have been named as defendants
in class action lawsuits relating to life insurance pricing and sales practices.
During 1998, National Life settled a group of class action lawsuits of this
nature. While the ultimate cost of the settlement is not yet known, National
Life set aside a reserve during 1998 of approximately $40.6 million to account
for the cost of the settlement of these cases.

         National Life is also party to ordinary routine litigation incidental
to the business, none of which is expected to have a material adverse effect
upon its ability to meet its obligations under the Policies.


                              FINANCIAL STATEMENTS


         The financial statements of National Life and of the relevant
Subaccounts of the Separate Account appear on the following pages. The financial
statements of National Life should be distinguished from the financial
statements of the Separate Account and should be considered only as bearing upon
National Life's ability to meet its obligations under the Policies.

                                  Monthly Policy Dates, as well as to measure

                                  not lapse and insurance coverage continues. To
                                  prevent lapse, the Owner must during the Grace
                                  Period make a premium payment equal to the sum
                                  of any amount by which the past Monthly
                                  Deductions have been in excess of Cash

                                   APPENDIX A

  ILLUSTRATION OF DEATH BENEFITS, ACCUMULATED VALUES AND CASH SURRENDER VALUES

         The following tables illustrate how the Death Benefits, Accumulated
Values and Cash Surrender Values of a Policy may change with the investment
experience of the Separate Account. The tables show how the Death Benefits,
Accumulated Values and Cash Surrender Values of a Policy issued to an Insured of
a given age, sex and Rate Class would vary over time if the investment return on
the assets held in each Portfolio of each of the Funds were a uniform, gross,
annual rate of 0%, 6% and 12%.

   
        The tables on Pages A-2 to A-7 illustrate a Policy issued to a male
Insured, Age 40 in the Preferred Nonsmoker Rate Class with a Face Amount of
$250,000 and Planned Periodic Premiums of $3,000 for Death Benefit Option A, and
$4,000 for Death Benefit Option B, in each case paid at the beginning of each
Policy Year. The Death Benefits, Accumulated Values and Cash Surrender Values
would be lower if the Insured was in a standard nonsmoker, smoker or substandard
class since the cost of insurance charges are higher for these classes. Also,
the values would be different from those shown if the gross annual investment
returns averaged 0%, 6% and 12% over a period of years, but fluctuated above and
below those averages for individual Policy Years. The net annual rate of return
shown in the tables is the gross annual rate reduced to reflect the average
investment advisory fee and average operating expenses of the Funds after
reimbursement and the Mortality and Expense Risk Charge.
    

         The second column of the tables show the amount to which the premiums
would accumulate if an amount equal to those premiums were invested to earn
interest, after taxes, at 5% compounded annually. The columns shown under the
heading "Guaranteed" assume that throughout the life of the policy, the monthly
charge for cost of insurance is based on the maximum level permitted under the
Policy (based on the 1980 CSO Smoker/Nonsmoker Table); the columns under the
heading "Current" assume that throughout the life of the Policy, the monthly
charge for cost of insurance is based on the current cost of insurance rate, and
for Policy Years after year 10, a bonus under which the Monthly Deductions are
reduced by 0.50% per annum.

   
     The amounts shown in all tables reflect an averaging of certain other asset
charges described below that may be assessed under the Policy, depending upon
how premiums are allocated. The total of the asset charges reflected in the
Current and Guaranteed illustrations, including the Mortality and Expense Risk
Charge of 0.90%, is 1.72%. This total charge is based on an assumption that an
Owner allocates the Policy values equally among the Subaccounts of the Separate
Account.
    

   
        These asset charges reflect an investment advisory fee of 0.65%, which
represents simple average of the fees incurred by the Portfolios during 1998 and
expenses of 0.17% which is based on an average of the actual expenses incurred
by the Portfolios during 1998, adjusted, as appropriate, to take into account
expense reimbursement arrangements expected to be in place for 1999. In the
absence of the reimbursement arrangements for some of the Portfolios, the other
asset charges would have totalled an average of 0.64%. If the reimbursement
arrangements were discontinued, the Accumulated Values and Cash Surrender Values
of a Policy which allocates Policy values equally among the Subaccounts would be
lower than those shown in the following tables. For information on Fund
expenses, see the prospectuses for the Funds accompanying this prospectus.
    

         The tables also reflect the fact that no charges for Federal or state
income taxes are currently made against the Separate Accounts. If such a charge
is made in the future, it would take a higher gross annual rate of return to
produce the same Policy values.

         The tables illustrate the Policy values that would result based upon
the hypothetical investment rates of return if premiums are paid and allocated
as indicated, no amounts are allocated to the General Account, and no Policy
loans are made. The tables are also based on the assumption that the Owner has
not requested an increase or decrease in the Face Amount, that no Withdrawals
have been made and no transfers have been made in any Policy Year.

         Upon request, National Life will provide a comparable illustration
based upon the proposed Insured's Age and Rate Class, the Death Benefit Option,
Face Amount, Planned Periodic Premiums and Riders requested.

The Death Benefit may, and the Accumulated Values and Cash Surrender Values
will, differ if premiums are paid in different amounts or frequencies.

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. THE DEATH
BENEFIT, ACCUMULATED VALUE AND CASH SURRENDER VALUE FOR A POLICY WOULD BE
DIFFERENT FROM THOSE SHOWN IF ACTUAL RATES OF INVESTMENT RETURN APPLICABLE TO
THE POLICY AVERAGED 0%, 6% OR 12% OVER A PERIOD OF YEARS, BUT ALSO FLUCTUATED
ABOVE OR BELOW THAT AVERAGE FOR INDIVIDUAL POLICY YEARS. THE DEATH BENEFIT,
ACCUMULATED VALUE AND CASH SURRENDER VALUE WOULD ALSO BE DIFFERENT FROM THOSE
SHOWN, DEPENDING ON THE INVESTMENT ALLOCATIONS MADE TO THE SUBACCOUNTS OF THE
SEPARATE ACCOUNT AND THE DIFFERENT RATES OF RETURN OF THE SUBACCOUNTS IF THE
ACTUAL RATES OF INVESTMENT RETURN APPLICABLE TO THE POLICY AVERAGED 0%, 6%, OR
12%, BUT VARIED ABOVE OR BELOW THAT AVERAGE FOR PARTICULAR SUBACCOUNTS. NO
REPRESENTATIONS CAN BE MADE THAT THESE HYPOTHETICAL RATES OF RETURN CAN BE
ACHIEVED FOR ANY ONE YEAR OR SUSTAINED OVER ANY PERIOD OF TIME.

The Death Benefit may, and the Accumulated Values and Cash Surrender Values
will, differ if premiums are paid in different amounts or frequencies.

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. THE DEATH
BENEFIT, ACCUMULATED VALUE AND CASH SURRENDER VALUE FOR A POLICY WOULD BE
DIFFERENT FROM THOSE SHOWN IF ACTUAL RATES OF INVESTMENT RETURN APPLICABLE TO
THE POLICY AVERAGED 0%, 6% OR 12% OVER A PERIOD OF YEARS, BUT ALSO FLUCTUATED
ABOVE OR BELOW THAT AVERAGE FOR INDIVIDUAL POLICY YEARS. THE DEATH BENEFIT,
ACCUMULATED VALUE AND CASH SURRENDER VALUE WOULD ALSO BE DIFFERENT FROM THOSE
SHOWN, DEPENDING ON THE INVESTMENT ALLOCATIONS MADE TO THE SUBACCOUNTS OF THE
SEPARATE ACCOUNT AND THE DIFFERENT RATES OF RETURN OF THE SUBACCOUNTS IF THE
ACTUAL RATES OF INVESTMENT RETURN APPLICABLE TO THE POLICY AVERAGED 0%, 6%, OR
12%, BUT VARIED ABOVE OR BELOW THAT AVERAGE FOR PARTICULAR SUBACCOUNTS. NO
REPRESENTATIONS CAN BE MADE THAT THESE HYPOTHETICAL RATES OF RETURN CAN BE
ACHIEVED FOR ANY ONE YEAR OR SUSTAINED OVER ANY PERIOD OF TIME.

                        Report of Independent Accountants



To the Board of Directors and Policyholders
of National Life Insurance Company


In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations and comprehensive income, changes in
equity, and cash flows present fairly, in all material respects, the financial
position of National Life Insurance Company and its subsidiaries (the Company)
at December 31, 1998 and 1997, and the results of their operations and their
cash flows for the years then ended in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
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 provide a
reasonable basis for the opinion expressed above.

As discussed in Note 10 to the financial statements, the Company changed its
method of accounting in 1998 for the cost of computer software developed or
obtained for internal use.

As discussed in Note 11 to the financial statements, on January 1, 1999,
National Life Insurance Company converted from a mutual to a stock insurance
company as part of a reorganization into a mutual holding company corporate
structure.

NATIONAL LIFE INSURANCE COMPANY and SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - NATURE OF OPERATIONS

Life is also known by its registered trade name "National Life of Vermont".
National Life employs about 750 people in its home office in Montpelier,
Vermont. With its affiliates and subsidiaries, National Life offers a broad
range of financial products and services, including life insurance, annuities,

Through affiliates National Life also distributes and provides investment
advisory and administrative services to the Sentinel Group Funds, Inc. The
Sentinel Funds' $3.1 billion of net assets represent thirteen mutual funds
managed on behalf of about 116,000 individual, corporate and institutional
shareholders worldwide.


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The accompanying consolidated financial statements of National Life and
subsidiaries have been prepared in conformity with generally accepted accounting
principles (GAAP).

The consolidated financial statements include the accounts of National Life
Insurance Company and its subsidiaries. All significant intercompany
transactions and balances have been eliminated in consolidation. Certain
reclassifications have been made to conform prior periods presented to the
current year's presentation.

The preparation of financial statements in conformity with GAAP 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.

INVESTMENTS

Cash and cash equivalents include highly liquid debt instruments purchased with
remaining maturities of three months or less.

Available-for-sale debt securities and equity securities are reported at
estimated fair value. Debt and equity securities that experience declines in
value that are other than temporary are written down with a corresponding charge
to realized losses.


                                      F-7

    
<PAGE>   78
   

Mortgage loans are reported at amortized cost, less valuation allowances for the
excess, if any, of the amortized cost of impaired loans over the estimated fair
value of the related collateral. Changes in valuation allowances are included in
net realized gains and losses.

Policy loans are reported at their unpaid balance and are fully collateralized
by related cash surrender values.

Real estate investments are reported at depreciated cost. Real estate acquired
in satisfaction of debt is transferred to real estate at estimated fair value.

Net realized investment gains and losses are recognized using the specific
identification method and include changes in valuation allowances. Changes in
the estimated fair values of available-for-sale debt and equity securities are
reflected in comprehensive income after adjustments for related deferred policy
acquisition costs, present value of future profits of insurance acquired, income
taxes and minority interests.

DEFERRED POLICY ACQUISITION COSTS

Commissions and other costs of acquiring business that vary with and are
primarily related to the production of new business are generally deferred.

Deferred policy acquisition costs for participating life insurance, universal
life insurance and investment-type annuities are amortized in relation to
estimated gross margins or profits. Amortization is adjusted retrospectively for
actual experience and when estimates of future gross margins or profits are
revised. Balances of deferred policy acquisition costs for these products are
adjusted for related unrealized gains and losses on available-for-sale debt and
equity securities through comprehensive income, net of related income taxes.

Deferred policy acquisition costs for non-participating term life insurance and
disability income insurance is amortized in relation to premium income using
assumptions consistent with those used in computing policy benefit liabilities.

Balances of deferred policy acquisition costs are regularly evaluated for
recoverability from product margins or profits.

PRESENT VALUE OF FUTURE PROFITS OF INSURANCE ACQUIRED

Present value of future profits of insurance acquired is the
actuarially-determined present value of future projected profits from policies
in force at the date of their acquisition, and is amortized in relation to gross
profits of those policies. Amortization is adjusted retrospectively for actual
experience and when estimates of future profits are revised.

PROPERTY AND EQUIPMENT

Property and equipment is reported at depreciated cost. Real property is
depreciated over 40 years using the straight-line method. Furniture and
equipment is depreciated using accelerated depreciation methods over 7 years and
5 years, respectively.

SEPARATE ACCOUNTS

Separate accounts are segregated funds relating to certain variable annuity and
variable life policies, and National Life's pension plans. Separate account
assets are primarily common stocks, bonds, mortgage loans, and real estate and
are carried at estimated fair value. Separate account liabilities reflect
separate account policyholders' interests in separate account assets, include
the actual investment performance of the respective accounts and are not
guaranteed. Separate account results relating to these policyholders' interests
are excluded from revenues and expenses.

POLICY LIABILITIES

Policy benefit liabilities for participating life insurance are developed using
the net level premium method, with interest and mortality assumptions used in
calculating policy cash surrender values. Participating life insurance terminal
dividends are accrued in relation to gross margins.

Policy benefit liabilities for non-participating life insurance, disability
income insurance and certain annuities are developed using the net level premium
method, with assumptions for interest, mortality, morbidity, withdrawals and
expenses based principally on company experience.

Policyholders' account balances for universal life insurance and investment-type
annuities represent amounts that inure to the benefit of the policyholders
(before surrender charges).

POLICYHOLDERS' DIVIDENDS

Policyholders' dividends are the pro-rata amount of dividends earned that will
be paid or credited at the next policy anniversary. Dividends are based on a
scale that seeks to reflect the relative contribution of each group of policies
to National Life's overall operating results. The dividend scale is approved
annually by National Life's Board of Directors.

RECOGNITION OF INSURANCE INCOME AND RELATED EXPENSES

Premiums from traditional life and certain annuities are recognized as revenue
when due from the policyholder. Benefits and expenses are matched with income by
providing for policy benefit liabilities and the deferral and amortization of
policy acquisition costs so as to recognize profits over the life of the
policies.

Premiums from universal life and investment-type annuities are reported as
increases in policyholders' accounts. Revenues for these policies consist of
mortality charges, policy administration fees and surrender charges deducted
from policyholders' accounts. Policy benefits charged to expense include benefit
claims in excess of related policyholders' account balances.

Premiums from disability income policies are recognized as revenue over the
period to which the premiums relate.

FEDERAL INCOME TAXES

National Life files a consolidated federal income tax return that includes all
of its wholly-owned subsidiaries. Current federal income taxes are charged or
credited to operations based upon amounts estimated to be payable or recoverable
as a result of taxable operations for the current year. Deferred income tax
assets and liabilities are recognized based on temporary differences between
financial statement carrying amounts and income tax bases of assets and
liabilities using enacted income tax rates and laws.

Net other comprehensive income for 1998 of $21.2 million is presented net of
reclassifications to net income for gross gains realized during the period of
$9.0 million and net of tax and deferred acquisition cost offsets of $6.6
million.

The amortized cost and estimated fair values of debt securities by contractual
maturity at December 31, 1998 are shown below (in thousands). Expected
maturities may differ from contractual maturities because borrowers may have
the right to call or prepay obligations with or without call or prepayment
penalties.

National Life periodically lends certain U.S. government or corporate bonds to
approved counterparties to enhance the yield of its bond portfolio. National
Life receives cash collateral for at least 103% of the market value of
securities loaned. Collateral adequacy is evaluated daily and periodically
adjusted for changes in the market value of securities loaned. The carrying
values of securities loaned are unaffected by the transaction. Collateral held
(included in cash and cash equivalents) and the corresponding liability for
collateral held (included in other liabilities and accrued expenses) were $193.5
million and $19.8 million at December 31, 1998 and 1997, respectively.

National Life also periodically enters into repurchase agreements on U.S.
Treasury securities to enhance the yield of its bond portfolio. These
transactions are accounted for as financings because the securities received at
the end of the repurchase period are identical to the securities transferred.
There were no open transactions at December 31, 1998. The repurchase liability
is included in other liabilities and was $234.6 million at December 31, 1997.

Impaired loans are mortgage loans where it is not probable that all amounts due
under the contractual terms of the loan will be received. Impaired loans
without valuation allowances are mortgage loans where the estimated fair value
of the collateral exceeds the recorded investment in the loan. For these
impaired loans, interest income is recognized on an accrual basis, subject to
recoverability from the estimated fair value of the loan collateral. For
impaired loans with valuation allowances, interest income is recognized on a
cash basis.

DERIVATIVES

National Life purchases over-the-counter options and exchange-traded futures on
the Standard & Poor's 500 (S&P 500) index to hedge obligations relating to
equity indexed products. When the S&P 500 index increases, increases in the
intrinsic value of the options and fair value of futures are offset by increases
in equity indexed product account values. When the S&P 500 index decreases,
National Life's loss is the decrease in the fair value of futures and is limited
to the premium paid for the options.

National Life purchases options only from highly rated counterparties. However,
in the event a counterparty failed to perform, National Life's loss would be
equal to the fair value of the net options held from that counterparty.

The option premium is expensed over the term of the option. Amortization of the
option premium is reflected in investment income. Interest credited includes
amounts that would be credited on the next policy anniversary based on the S&P
500 index's value at the reporting date, offset by changes in the intrinsic
value of options held and changes in the fair value of futures. The call options
are included in other invested assets and are carried at amortized cost plus
intrinsic value, if any, of the call options as of the valuation date.

For cash and cash equivalents carrying value approximates estimated fair value.

Debt and equity securities estimated fair values are based on quoted values
where available. Where quoted values are not available, estimated fair values
are based on discounted cash flows using current interest rates of similar
securities.

Mortgage loan fair values are estimated as the average of discounted cash flows
under different scenarios of future mortgage interest rates (including
appropriate provisions for default losses and borrower prepayments).

For variable rate policy loans the unpaid balance approximates fair value. Fixed
rate policy loan fair values are estimated based on discounted cash flows using
the current variable policy loan rate (including appropriate provisions for
mortality and repayments).

Derivatives estimated fair values are based on quoted values.

Investment products include flexible premium annuities, single premium deferred
annuities and supplementary contracts not involving life contingencies.
Investment product fair values are estimated as the average of discounted cash
flows under different scenarios of future interest rates of A-rated corporate
bonds and related changes in premium persistency and surrenders.

Debt fair values are estimated based on discounted cash flows using current
interest rates of similar securities.


NOTE 4 - INSURANCE IN-FORCE AND REINSURANCE

National Life reinsures certain risks assumed in the normal course of business.
For individual life products, National Life generally retains no more than $3.0
million of risk on any person (excluding accidental death benefits and dividend
additions). Reinsurance for life products is ceded under yearly renewable term,
coinsurance, and modified coinsurance. Disability income products are
significantly reinsured under coinsurance and modified coinsurance.

National Life remains liable in the event any reinsurer is unable to meet its
assumed obligations. National Life regularly evaluates the financial condition
of its reinsurers and concentrations of credit risk of reinsurers to minimize
its exposure to significant losses from reinsurer insolvencies.

The effects of reinsurance for the years ended December 31 were as follows (in
thousands):

Management believes it is more likely than not that National Life will realize
the benefit of deferred tax assets.

National Life's federal income tax returns are routinely audited by the IRS.
The IRS has examined tax returns through 1993 and is currently examining the
years 1994 and 1995. In management's opinion adequate tax liabilities have been
established for all open years.

NOTE 6 - BENEFIT PLANS

National Life sponsors a qualified defined benefit pension plan covering
substantially all employees. The plan is administered by National Life's
Benefits Committee and is non-contributory, with benefits based on an
employee's retirement age, years of service and compensation near retirement.
Plan assets are primarily bonds and common stocks held in a National Life
separate account and funds invested in an annuity contract issued by National
Life. National Life also sponsors other, non-qualified pension plans, including
a non-contributory defined benefit plan for general agents that provides
benefits based on years of service and sales levels, a contributory defined
benefit plan for certain employees, agents and general agents and a
non-contributory defined supplemental benefit plan for certain executives.
These non-qualified defined benefit pension plans are not funded.

National Life sponsors four defined benefit postretirement plans that provide
medical, dental and life insurance benefits to employees and agents.
Substantially all employees and agents may be eligible for retiree benefits if
they reach normal retirement age and meet certain minimum service requirements
while working for National Life. Most of the plans are contributory, with
retiree contributions adjusted annually, and contain cost sharing features such
as deductibles and copayments. The plans are not funded and National Life pays
for plan benefits on a current basis. The cost of these benefits is recognized
as earned.

During 1997, National Life offered enhanced pension and postretirement benefits
to employees meeting certain defined eligibility requirements. The program
resulted in special termination benefits for the expected present value of the
enhancements to benefits, curtailment gains for reductions in the pension
benefit obligations relating to assumed increases in future compensation levels
and settlement gains for the pro-rata recognition of actuarial gains on lump
sum settlements of pension benefit obligations.

The status of the defined benefit plans at December 31 was as follows (in

The total projected benefit obligation for non-qualified defined benefit pension
plans was $81.4 million and $69.1 million at December 31, 1998 and 1997,
respectively. The total accumulated benefit obligation for these plans was $75.2
million and $66.3 million at December 31, 1998 and 1997, respectively.

The actuarial assumptions used in determining benefit obligations at December
31, were as follows:

Health care cost trend rates grade to 5% in year 2000 and remain level
thereafter. Increasing the assumed health care trend rates by one percentage
point in each year would increase the APBO by about $3.2 million and the 1998
service and interest cost components of net periodic postretirement benefit cost
by about $0.1 million. Decreasing the assumed health care trend rates by one
percentage point in each year would reduce the APBO by about $2.6 million and
the 1998 service and interest cost components of net periodic postretirement
benefit cost by about $0.1 million. National Life uses the straight-line method
of amortization for prior service cost and unrecognized gains and losses.

National Life provides employee savings and 401(k) plans where up to 3% of an
employee's compensation may be invested by the employee in either plan with
matching funds contributed by the company. National Life also contributes
various amounts of an employee's compensation (up to certain levels) to a 401(k)
account. Additional voluntary employee contributions may be made to the plans
subject to certain limits. Company contributions to these plans generally vest
within two years.

NOTE 8 - SALES PRACTICE REMEDIATION COSTS

During 1997, several class action lawsuits were filed against National Life in
various states related to the sale of life insurance policies during the 1980's
and 1990's. National Life specifically denied any wrongdoing. National Life
agreed to a settlement of these class action lawsuits in June 1998. This
agreement was subsequently approved by the court in October 1998. The settlement
provides class members with various policy enhancement options and new product
purchase discounts. Class members may instead pursue alternative dispute
resolution according to predetermined guidelines. Management believes that while
the ultimate cost of this litigation is still uncertain, it is unlikely (after
considering existing provisions) to have a material adverse effect on National
Life's financial position.

NOTE 9 - STATUTORY INFORMATION

National Life prepares statutory basis financial statements for regulatory
filings with insurance regulators in all 50 states and the District of Columbia.

NOTE 10 - NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities (FAS 133), which establishes accounting and reporting
standards for derivative instruments. FAS 133 requires that an entity recognize
all derivatives as either assets or liabilities at fair value in the statement
of financial position, and establishes special accounting for the following
three types of hedges: fair value hedges, cash flow hedges, and hedges of
foreign currency exposures of net investments in foreign operations. The
statement is effective for fiscal years beginning after June 15, 1999. National
Life is currently assessing the impact of the adoption of FAS 133.

In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use (SOP 98-1). SOP 98-1 requires that
certain costs incurred in developing internal use computer software be
capitalized and provides guidance for determining whether computer software is
considered to be for internal use. This statement is effective for fiscal years
beginning after December 15, 1998. National Life adopted SOP 98-1 effective
January 1, 1998. The adoption of SOP 98-1 resulted in net after tax
capitalization (after current year amortization) of approximately $2 million in
software costs.

NOTE 11 - SUBSEQUENT EVENTS

On January 1, 1999, National Life converted from a mutual to a stock insurance
company as part of a reorganization into a mutual holding company corporate
structure.

Prior to the conversion, policyowners held policy contractual and membership
rights from National Life. The contractual rights, as defined in the various
insurance and annuity policies, remained with National Life after the
conversion. Membership interests held by policyowners of National Life at
December 31, 1998 were converted to membership interests in National Life
Holding Company, an upstream corporation. National Life Holding Company
currently owns all the outstanding shares of NLV Financial, which in turn
currently owns all the outstanding shares of National Life.

This reorganization was approved by policyowners of National Life and was
completed with the approval of the Vermont Department of Banking, Insurance,
Securities, and Health Care Administration.

                        REPORT OF INDEPENDENT ACCOUNTANTS






To the Board of Directors of National Life Insurance Company
and Policyholders of National Variable Life Insurance Account - Varitrak Segment


In our opinion, the accompanying statement of net assets and the related
statements of operations and of changes in net assets present fairly, in all
material respects, the financial position of each of the sub-accounts
constituting the National Variable Life Insurance Account - Varitrak Segment (a
segment within a Separate Account of National Life Insurance Company) (the
Segment) at December 31, 1998, and the results of each of their operations and
each of their changes in net assets for the years ended December 31, 1998 and
1997 and the period from March 11, 1996 through December 31, 1996, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Segment'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 audits 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 confirmation of securities at December 31, 1998 by
correspondence with the funds, provide a reasonable basis for the opinion
expressed above.

services for certain Market Street Fund, Inc. mutual fund portfolios.

National Life maintains two segments within the Variable Account. The Varitrak
Segment (the Segment) within the Variable Account was established on March 11,
1996 and is used exclusively for National Life's flexible premium variable life
insurance products known collectively as Varitrak. On May 1, 1998, National Life
established the Estate Builder Segment within the Variable Account to be used
exclusively for National Life's flexible premium variable life insurance
products known collectively as Estate Builder.

The Segment invests the accumulated policyholder account values in shares of
mutual fund portfolios within Market Street Fund, Inc., Alger American Fund,
Variable Insurance Products Fund (VIPF), American Century, JP Morgan, Strong
Capital, Neuberger & Berman and Goldman Sachs. Net premiums received by the
Segment are deposited in investment portfolios as designated by the
policyholder, except for initial net premiums on new policies which are first
invested in the Market Street Fund Money Market Portfolio. Policyholders may
also direct the allocations of their account value between the various
investment portfolios within the Segment and a declared interest account (within
the General Account of National Life) through participant transfers.

There are twenty-six sub-accounts within the Segment. Each sub-account, which
invests exclusively in the shares of the corresponding portfolio, comprises the
accumulated policyholder account values of the underlying variable life
insurance policies investing in the sub-account.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

These financial statements have been prepared in conformity with generally
accepted accounting principles (GAAP). The preparation of financial statements
in accordance with GAAP requires management to make estimates and assumptions
that affect the reported amounts and disclosures in the financial statements.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed in the preparation of the
Segment's financial statements.

INVESTMENTS

The mutual fund portfolios consist of the Market Street Fund Money Market,
Market Street Fund Growth (formerly Market Street Fund Common Stock), Market
Street Fund Aggressive Growth, Market Street Fund Managed, Market Street Fund
Bond, Market Street Fund International, Market Street Fund Sentinel Growth,
Alger American Growth, Alger American Small Capitalization, VIPF Equity-Income,
VIPF Overseas, VIPF Growth, VIPF High Income, VIPF Contra, VIPF Index 500,
American Century Value, American Century Income & Growth, JP Morgan
International Opportunities, JP Morgan Small Company, Strong Capital Management
Opportunity II, Strong Capital Management Growth II, Neuberger & Berman
Partners, Goldman Sachs International Equity, Goldman Sachs Global Income,
Goldman Sachs CORE Small Cap Equity, and Goldman Sachs Mid Cap Equity Fund (the
Portfolios). The American Century, JP Morgan, Strong Capital, Neuberger &
Berman, and Goldman Sachs mutual fund portfolios were added to

the Segment in 1998. The assets of each portfolio are held separate from the
assets of the other portfolios and each has different investment objectives and
policies. Each portfolio operates separately and the gains or losses in one
portfolio have no effect on the investment performance of the other portfolios.

INVESTMENT VALUATION

The investments in the Portfolios are valued at the closing net asset value per
share as determined by the portfolio at the end of each period. The change in
the difference between cost and market value is reflected as unrealized gain
(loss) in the Statement of Operations.

INVESTMENT TRANSACTIONS

Investment transactions are accounted for on the trade date (date the order to
buy or sell is executed) and dividend income (including capital gain
distributions) are recorded on the ex-dividend date. The cost of investments
sold was determined using the average cost method prior to 1998. Effective
January 1, 1998, the Variable Account changed its method of calculating the cost
of investments sold from the average cost method to the first in, first out
method (FIFO). Management believes FIFO better matches policyholder and
sub-account investment activity. This change had no impact on the results of
operations for 1998 or prior years, and no impact on the unit value reported
within each of the sub-accounts. Management also believes it would be
impractical to calculate the cumulative effect of this change on previously
reported realized and unrealized gains and losses; however, during 1998 the
change increased net realized gains by $ 176,300 and decreased net unrealized
gains by the same amount.

FEDERAL INCOME TAXES

The operations of the Segment are part of, and taxed with, the total operations
of National Life. Under existing federal income tax law, investment income and
capital gains attributable to the Segment are not taxed.

NOTE 3 - CHARGES AND EXPENSES

National Life deducts a daily charge from the Segment based on an annual rate of
 .9% of each sub-account's net asset value for its assumption of mortality and
expense risks. The mortality risk assumed is that the insureds under the
policies may die sooner than anticipated. The expense risk assumed is that
expenses incurred in issuing and administering the policies may exceed expected
levels.

Cost of insurance charges are deducted monthly from each policyholder's
accumulated account value for the insurance protection provided and are remitted
to National Life. These charges vary based on the net amount at risk, attained
age of the insured, and other factors. As partial compensation for
administrative services provided, National Life also deducts a monthly
administrative charge from each policyholder's accumulated account value.

Certain deferred administrative and sales charges are deducted from the
policyholder's accumulated account value if the underlying variable life
insurance policy is surrendered or lapsed prior to the end of the fifteenth
policy year.

NOTE 6 - LOANS

Policyholders may obtain loans after the first policy year as outlined in the
variable life insurance policy. At the time a loan is granted, accumulated value
equal to the amount of the loan is designated as collateral and transferred from
the Segment to the General Account of National Life. Interest is credited by
National Life at predetermined rates on collateral held in the General Account.
This interest is periodically transferred to the Segment.

NOTE 7 - DISTRIBUTION OF NET INCOME

The Segment does not expect to declare dividends to policyholders from
accumulated net income. The accumulated net income will be distributed to
policyholders as withdrawals (in the form of death benefits, surrenders or
policy loans) in excess of the policyholders' net contributions to the Segment.

         This prospectus describes the VariTrak policy, a variable universal
life insurance policy offered by National Life Insurance Company. This Policy
combines insurance and investment features. The policy's primary purpose is to
provide insurance protection on the life of the insured person. You can make
premium payments at various times and in various amounts. You can also allocate
premiums among a number of funds with different investment objectives, and you
can increase or decrease the death benefit payable under your policy. This
Prospectus offers the policy only in the State of New York.

         We deduct certain charges from premium payments. Then these premium
payments go to the National Variable Life Insurance Account, a separate account
of National Life, or to the general account, or a combination of the two. The
general account pays interest at rates guaranteed to be at least 4%. The
separate account has twenty-six subaccounts. Each subaccount buys shares of a
specific fund portfolio. The available funds are:

The value of your policy will depend upon the investment results of the funds
you select. You bear the entire investment risk for all amounts allocated to the
separate account; there is no guaranteed minimum value for any of the funds, and
the value of your policy may be more or less than premiums paid.

You must receive, with this prospectus, current prospectuses for all of the fund
options. They describe the investment objectives and the risks of the funds.

The value of your policy will also reflect our charges. These include a premium
tax charge, cost of insurance charges, a mortality and expense risk charge, an
administrative charge, and certain other charges. During the first five years
your policy will remain in force if specified premiums are paid on time, or if
the policy has enough value to pay the monthly charges as they become due. After
the fifth year, the Policy will remain in force only so long as it has enough
value to pay the monthly charges as they become due.

We recommend that you read this prospectus carefully. You should keep it to
refer to later.

Investments in these contracts are not deposits or obligations of, and are not
guaranteed or endorsed by, adviser of any of the underlying funds identified
above, the U.S. government, or any bank or bank affiliate. Investments are not
<PAGE>   114
federally insured by the Federal Deposit Insurance Corporation, the Federal
Reserve Board, or any other governmental agency.

It may not be advantageous to purchase a policy as a replacement for another
type of life insurance or as a means to obtain additional insurance protection
if you already own another variable universal life insurance policy.

THE SECURITIES AND EXCHANGE COMMISSION HAS NOT APPROVED OR DISAPPROVED THE
POLICY OR DETERMINED IF THIS PROSPECTUS IS ACCURATE OR COMPLETE. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                        SUMMARY DESCRIPTION OF THE POLICY

      You should read this summary of the policy provisions together with the
detailed information appearing later in this Prospectus. Unless otherwise noted,
this Prospectus assumes the insured person is alive. The precise meanings of the
few capitalized terms used in this summary can be found in the Glossary, on
pages to .

THE POLICY

      National Life Insurance Company issues the VariTrak variable universal
life insurance policy. This life insurance policy allows you, within limits, to
make premium payments in any amount and whenever you like. As long as the policy
remains in force, it will provide for:

         (1)      Life insurance coverage which will provide a death benefit on
                  the death of the named insured person;

         (2)      A cash surrender value;

         (3)      Surrender and withdrawal rights and policy loan privileges;
                  and

   
         (4)      A variety of additional insurance benefits. (Where provided
                  by optional riders, so long as these riders remain in force).
    

         This policy is designed to help lessen the economic loss resulting from
the death of the insured person. You should consider your need for insurance
coverage and the policy's investment potential on a long-term basis. The policy
matures, resulting in payment of cash surrender value, when the insured reaches
age 99.

   
         There is no fixed schedule for premium payments, although you may
establish a schedule of planned periodic premiums. You may also, after a year
and within limits, increase or decrease the policy's face amount, and you may
change the death benefit option. The policy's value and death benefit will
fluctuate based on the investment results of the chosen fund portfolios, the
crediting of interest to the general account, and the deduction of charges.
    

         Lapse. The policy will not lapse simply because you do not pay any
particular amounts of premiums. However, the payment of premiums in any amount
or frequency will not necessarily guarantee that the policy will remain in
force. In general, the policy will lapse if it does not have enough value to pay
the monthly charges as they become due. During the first five years, the policy
will not lapse even if its value is not enough to pay the monthly charges, if at
least specified amounts of premiums have been paid (these amounts are defined in
the Glossary as the Minimum Guarantee Premium). See "How the Duration of the
Policy May Vary," page .

   
        Optional Guaranteed Death Benefit Rider. In addition, if you buy the
optional Guaranteed Death Benefit Rider, your policy will not lapse even if its
value is not enough to pay the monthly charges, if you have paid at least the
Minimum Guarantee Premium, until the later of 20 years from the date the policy
is issued or the insured person attains age 70. See "Optional Benefits -
Guaranteed Death Benefit Rider," page .
    


                                       3
<PAGE>   118

         If you already have life insurance, you should consider whether or not
changing or adding to existing coverage would be advantageous. It may not be
advisable to purchase another policy as a replacement for an existing policy.

THE SEPARATE ACCOUNT

         The separate account is divided into subaccounts, 26 of which are
available under this policy. Each of these subaccounts buys shares of a
corresponding fund portfolio. See "National Life Insurance Company, the Separate
Account, and the Funds," page .

         We cannot give any assurance that any portfolio will achieve its
investment objectives. You bear the entire investment risk on the value of your
policy which you allocate to the separate account.

AVAILABILITY OF POLICY

         We will issue this policy for insured persons from ages 0 to 85. The
minimum face amount is generally $50,000, although exceptions to this minimum
may be made for employee benefit plans. Before issuing a policy, we will require
that the proposed insured person meet certain underwriting standards. We will
assign the insured person to one of the following types of rate classes:

    -    Preferred Nonsmoker

    -    Standard Nonsmoker

    -    Smoker

   
    -    Juvenile, or
    

    -    Substandard.

See "Issuance of a Policy," Page .

THE DEATH BENEFIT

   
         As long as your policy remains in force, we will pay the death benefit
to your beneficiary, when we receive due proof of the death of the insured
person. The death benefit will be increased by any additional benefits provided
by a supplementary benefit rider. The death benefit will be reduced by any
outstanding policy loans and accrued interest, and any unpaid monthly
deductions.
    

         There are two death benefit options available, which we call Option A
and Option B. You may choose which option will apply to your policy.

      If you choose death benefit Option A, the death benefit will be based on
the greater of :

      (a)      the face amount, or

      (b)      the Accumulated Value multiplied by a factor specified by
               federal income tax law.

         If you choose death benefit Option B, the death benefit will be based
on the greater of:

(a)      the face amount plus the Accumulated Value, or


                                       4
<PAGE>   119

(b)      the Accumulated Value multiplied by the same factor that applies to
         option A.

See "Death Benefit Options," Page ___.

FLEXIBILITY TO ADJUST AMOUNT OF DEATH BENEFIT

         After a year, you may adjust the death benefit by changing the death
benefit option or by increasing or decreasing the face amount of your policy.
(See "Change in Death Benefit Option," Page ___, and "Ability to Adjust Face
Amount," Page ___.)

         Any change in death benefit option or in the face amount may affect the
charges under your policy. If you increase the face amount, your monthly charges
will increase. A decrease in face amount may decrease the monthly charges. (See
"Cost of Insurance Charge," Page ___.)

         If you request a decrease in face amount which would cause the policy
not to qualify as life insurance under federal tax law, we will not allow the
decrease.

ACCUMULATED VALUE

         The Accumulated Value is the total amount of value held in the policy
at any time. It equals the sum of the amounts held in the separate account and
the general account. (See "Calculation of Accumulated Value," Page .)

         The Accumulated Value in the separate account will reflect:

    -    the investment performance of your chosen funds

    -    premiums paid

    -    transfers

    -    withdrawals

    -    policy loans

    -    loan repayments

   
    -    loan interest charged, and
    

    -    the charges assessed in connection with the policy.

         We pay interest on Accumulated Value in the general account at rates we
declare in advance for specific periods. We guarantee that these rates will be
at least 4%. (See "The General Account," Page ___.)

   
         The Accumulated Value will likely impact both the death benefit and 
the cost of insurance charges.
    

ALLOCATION OF PREMIUMS

         You will specify, in the application for your policy, the percentages
of premium to go to each subaccount of the separate account or to the general
account. You may change these percentages whenever you like. You may choose
among all 26 available subaccounts of the separate account. However, we may
limit the number of different subaccounts, other than the money market
subaccount, used in your policy over its entire life to 16.

   
         We will allocate all premiums, after reduction for premium taxes, 
received during the free-look period that are to go to the separate account to
the money market subaccount. At the end of the free look period, we will move
the amount in the money market subaccount
    


                                       5
<PAGE>   120
   
(including investment experience) to your chosen subaccounts. For this purpose,
we will assume that the free-look period ends 20 days after the date the policy
is issued. Premiums received after the free look period ends will be allocated
directly to your chosen subaccounts. (See "Allocation of Net Premiums," 
Page ___.)
    

TRANSFERS

         You may transfer the amounts in the subaccounts and the general
account. Transfers between the subaccounts or from the separate account into the
general account will be made on the day we receive the request. We limit
transfers out of the general account to the greater of $1000 and 25% of the
Accumulated Value in the general account. We also allow only one transfer out of
the general account per year. See "Transfers," page .

FREE-LOOK PRIVILEGE

   
         The Policy provides for an initial "free-look" period, during which you
may cancel the Policy and receive a refund equal to the premiums you paid. This
free-look period ends on the latest of:
    

(a)      45 days after you sign Part A of your application for the Policy

(b)      10 days after you receive the Policy, and

(c)      10 days after we mail or personally deliver to you a Notice of
         Withdrawal Right,

or, in each case, any longer period provided by state law. To cancel your
policy, you must return the Policy to us or to our agent within such time with a
written request for cancellation. (See "Free-Look Privilege," Page .)

         We expect these reimbursement arrangements to continue, but there are
no legal obligations to continue these arrangements for any particular period of
time; if they are terminated, the affected Portfolios' expenses may increase.

         Premium Tax Charge. We deduct a premium tax charge from each premium
payment, to cover the cost of state and local premium taxes, and the federal DAC
tax. This charge is 3.25% of each premium. For qualified employee benefit plans,
the charge will be 2.00% of each premium rather than 3.25%. We may change the
amount of the charge deducted from future premiums if the applicable law
changes. (See "Premium Tax Charge," Page .)

         Monthly Deductions. On the date of issue and each month thereafter, we
will take a deduction from the Accumulated Value equal to the sum of:

    (a)  the monthly cost of insurance charge

    (b)  the monthly administrative charge, and

    (c)  if applicable, a charge for any additional benefits added by rider.

   
         We calculate the monthly cost of insurance charge by multiplying the
net amount at risk (that is, the unadjusted death benefit less the policy's
Accumulated Value) by the applicable cost of insurance rate(s). These rates will
depend upon the age, sex, and rate class of the insured person, the time the
coverage has been in force, your policy size, and on our expectations of future
mortality and expense experience. Our cost of insurance rates cannot exceed the
guaranteed maximum cost of insurance rates set forth in your policy. These
guaranteed maximum rates are based on the insured person's age, sex, rate class,
and the "1980 Commissioners Standard Ordinary Smoker and Nonsmoker Mortality
Table." (See "Cost of Insurance Charge," Page .)
    

   
         The monthly administrative charge is currently $7.50. (See "Monthly
Administrative Charge," Page .) 
    

   
         After 10 years, we will credit a separate account enhancement under 
which the Monthly Deductions are reduced by 0.50% per annum of the Accumulated
Value in the separate account. (See "Separate Account Enhancement," Page .) The
separate account enhancement is guaranteed.
    


                                       8
<PAGE>   123

         Surrender Charge. We impose a surrender charge if you surrender your
policy or it lapses at any time during the first 15 years. The surrender charge
consists of a deferred administrative charge and a deferred sales charge. (See
"Surrender Charge," Page .)

         The deferred administrative charge is generally initially $2 per $1,000
of initial fare amount (lower for insured people under 25 years old at issue).
After the first five years, the deferred administrative charge declines
linearly by month until the end of the fifteenth year, when it becomes zero.

         We calculate the deferred sales charge individually for each policy,
based on its surrender charge target premium. The surrender charge target
premium is based on the initial face amount, and the age, sex and rate class of
the insured person. It is used solely for the purpose of calculating the
deferred sales charge. Your surrender charge target premium will be shown in
your Policy.

         The deferred sales charge is equal to the lesser of:

         (a)      30% of the premiums received up to one surrender charge target
                  premium, plus 10% of all premiums paid in excess of this
                  amount but not greater than twice this amount, plus 9% of all
                  premiums paid in excess of twice this amount,

                  or

   
        (b)       the maximum deferred sales charge, which is based on the 
                  initial face amount, and the age, sex and rate class of the
                  insured person. The maximum deferred sales charge, which will
                  be shown in your policy, is level for the first five years,
                  and then declines linearly by month through the end of the
                  fifteenth year, when it becomes zero.
    

   
      Appendix B to this Prospectus contains a table showing the surrender
charge target premium and the maximum deferred sales charge for male and female
nonsmokers and smokers of each age at the time a policy is issued, expressed as
a dollar amount per $1000 of initial face amount.
    

      Daily Charge Against the Separate Account (Mortality and Expense Risk
Charge). We assess a daily charge for assuming certain mortality and expense
risks incurred in connection with the policies. This charge is currently 0.90%
annually of the average daily net assets of the separate account. (See
"Mortality and Expense Risk Charge," Page .)

      Withdrawal Charge. If you make a withdrawal from your policy, we assess
a withdrawal charge equal to the lesser of 2% of the amount withdrawn or $25.
(See "Withdrawal Charge," Page  .)

      Transfer Charge. You may transfer value among the subaccounts on any
business day, without charge. We have no current intent to impose a transfer
charge in the foreseeable future; however, we may impose in the future a charge
of 

                                       9

<PAGE>   124

$25 for each transfer in excess of twelve transfers in any one year. (See
"Transfer Charge," Page ___.)

      Projection Report Charge.  If you request a projection report, we may
impose a charge, not to exceed $25.  (See "Projection Report Charge," Page __.)

      Other Charges. Shares of the Portfolios are purchased by the subaccounts
at net asset value, which reflects management fees and expenses deducted from
the assets of the Portfolios. These management fees and expenses are shown above
under "Annual Charges of Underlying Funds".

LOAN PRIVILEGE

   
         After a year, you may borrow against your policy. The maximum amount of
all loans is the Cash Surrender Value less three times the most recent monthly
deduction. Policy loans may be taken, or repayments made, on any business day.
    

         We charge interest on Policy loans at a fixed rate of 6% per year.
Interest is added to the loan balance at the end of each policy year. You may
repay policy loans at any time and in any amount. When the death benefit becomes
payable or the policy is surrendered, we will deduct policy loans and accrued
interest from the proceeds otherwise payable. When you take a policy loan, we
will hold Accumulated Value in the general account as collateral for the policy
loan. We credit interest on amounts held in the general account as collateral
for policy loans at rates we declare prior to each calendar year. This rate will
be at least 4%.

   
         We will credit interest on Accumulated Value held as collateral for 
loans in the general account for policies that are more than 10 years old at
rates which are 0.50% per annum higher than those that apply to policies still
in their first ten years. We also currently plan to make preferred loans
available when the insured person is 65 years old or a policy is 20 years old,
whichever is later. These preferred loans will be limited in amount. For these
preferred policy loans, we will credit interest on the amount held in the
general account as collateral at an annual rate of 6%. However, we are not
obligated to continue to make preferred loans available, and we will make these
loans available in our sole discretion. (See "Loan Privileges," Page ___.)
    

         Loans may cause a policy to lapse, depending on investment performance
and the amount of the loan. If a policy is not a Modified Endowment Contract,
lapse with policy loans outstanding may result in adverse tax consequences. (See
"Tax Treatment of Policy Benefits," Page ___.)

<PAGE>   125

WITHDRAWAL OF CASH SURRENDER VALUE

   
         After a year, you may request a withdrawal of Cash Surrender Value.
Withdrawals must be at least $500 (except that we may permit smaller withdrawals
for employee benefit plans). Withdrawals cannot be more than the Cash Surrender
Value minus three times the most recent monthly deduction. We will take the 
withdrawal amount from the subaccounts based on your instructions. If you do not
provide instructions, we will take the withdrawal from the subaccount in
proportion to the values in the subaccounts. If the values in the subaccounts
will not allow us to carry out your instructions, we will not process the
withdrawal until you provide further instructions. You may not allocate
withdrawals to the general account until all the value in the separate account
has been exhausted. (See "Withdrawal of Cash Surrender Value," Page ___.)
    

SURRENDER OF THE POLICY

         You may surrender your policy at any time and receive the cash
surrender value, if any. The cash surrender value will equal the Accumulated
Value less any policy loan with accrued interest and any surrender charge. (See
"Surrender Privilege," Page ___.)

AVAILABLE AUTOMATED FUND MANAGEMENT FEATURES

      We currently offer, at no charge to you, two automated fund management
programs, Dollar Cost Averaging and Portfolio Rebalancing. For a description of
these features, see "Available Automated Fund Management Features," Page ___.

TAX TREATMENT

         Life insurance contracts receive tax-favored treatment under current
federal income tax law. Assuming that your policy qualifies as a life insurance
contract for federal income tax purposes, you should not be taxed on any
increase in cash surrender value while your policy remains in force. Also, your
beneficiary generally should not be taxed on death benefit proceeds. We believe
that a policy issued on a standard rate class basis generally should meet the
Section 7702 definition of a life insurance contract. For policies issued on a
substandard basis, there is insufficient guidance to determine if such a policy
would in all situations satisfy the Section 7702 definition of a life insurance
contract, particularly if you pay the full amount of premiums permitted under
the policy. (See "Tax Status of the Policy," Page ___.)

         A policy may be treated as a "Modified Endowment Contract" in some
situations. If your policy is a Modified Endowment Contract, then certain
pre-death distributions, including policy loans, will be treated first as a
distribution of taxable income and then as a return of basis or investment in
the contract. In addition, prior to age 59-1/2 any such distributions generally
will be subject to a 10% penalty tax. (For further discussion on the
circumstances under which a Policy will be treated as a Modified Endowment
Contract, See "Tax Treatment of Policy Benefits," Page ___.)

         If your policy is not a Modified Endowment Contract, distributions
generally will be treated first as a return of basis or investment in the
contract, and then as disbursing taxable income. Loans will not be treated as
distributions. Neither distributions nor loans from a policy that is not a
Modified Endowment Contract are subject to the 10% penalty tax. (See
"Distributions from Policies Not Classified as Modified Endowment Contracts,"
Page ___.)

      We offer other variable life insurance policies which also invest in the
same portfolios of the funds. These policies may have different charges that
could affect the value of the subaccounts and may offer different benefits more
suitable to your needs. To obtain more information about these policies, you may
write or call us at National Life Drive, Montpelier, Vermont 05604, (800)
537-7003.

ILLUSTRATIONS

         Illustrations of how investment performance of the subaccounts may
cause the death benefit, the Accumulated Value and the cash surrender value to
vary are included in Appendix A commencing on Page A-1.

         These illustrations of hypothetical values may help you understand the
long-term effects of different levels of investment performance, of charges and
deductions, and of electing one or the other death benefit option. They may also
be useful in generally comparing and contrasting this policy to other life
insurance policies. Nonetheless, the illustrations are based on hypothetical
investment rates of return. THEY ARE NOT GUARANTEED. Illustrations are not a
representation of past or future performance. Actual rates of return may be more
or less than those reflected in the illustrations and, therefore, actual values
will differ from those illustrated.

QUESTIONS

      If you have questions, you may write or call us at National Life Drive,
Montpelier, Vermont 05604, (800) 537-7003.

      NATIONAL LIFE INSURANCE COMPANY, THE SEPARATE ACCOUNT, AND THE FUNDS

NATIONAL LIFE INSURANCE COMPANY

   
         National Life Insurance Company ("National Life", or "we") is
authorized to transact life insurance and annuity business in Vermont and in 50
other jurisdictions. National Life was originally chartered as a mutual life
insurance company in 1848 under Vermont law. It is now a stock life insurance
company. All of its outstanding stock is indirectly owned by National Life
Holding Company, a mutual insurance holding company established under Vermont
law on January 1, 1999. All policyholders of National Life, including all the
Owners of the Contracts, are voting members of National Life Holding Company.
National Life assumes all insurance risks under the Policy and its assets
support the Policy's benefits. On December 31, 1998, National Life's
consolidated assets were over $9 billion. (See "Financial Statements," Page 
F-1.)
    

THE SEPARATE ACCOUNT

         We established the Separate Account on February 1, 1985 under Vermont
law. It is a separate investment account to which we allocate assets to support
the benefits payable under the policies, other policies we currently issue, and
other variable life insurance policies we may issue in the future.

         The Separate Account's assets are the property of National Life. The
portion of the Separate Account's assets equal to the reserves and other
liabilities under the Policies (and other policies) supported by the Separate
Account will not be exposed to liabilities arising out of any other business
that we may conduct. The portion of the Separate Account's assets equal to the
reserves and other liabilities under the Policies may, however, be exposed to
liabilities arising from other subaccounts of the Separate Account that fund
other variable life insurance policies. The Separate Account may also include
amounts derived from expenses we have charged to the Policies (and other
policies) which we currently hold in the Separate Account, and amounts held to
support other variable life insurance policies we may issue. From time to time
we may move these additional amounts to our General Account.

         The Separate Account is registered with the Securities and Exchange
Commission ("SEC") under the Investment Company Act of 1940 ("1940 Act") as a
unit investment trust type of investment company. Such registration does not
involve any supervision of the management or investment practices or policies of
the Separate Account by the SEC. The Separate Account meets the definition of a
"separate account" under Federal securities laws.

         You may choose among the Subaccount options described below. However,
we may limit the number of different Subaccounts, other than the Money Market
Subaccount, used in any one Policy over its entire life to 16.

THE MARKET STREET FUND

         The Growth, Sentinel Growth, Aggressive Growth, Bond, Managed,
International, and Money Market Subaccounts of the Separate Account invest in
shares of The Market Street Fund, Inc., a "series" type of mutual fund which is
registered with the SEC under the 1940 Act as a diversified open-end management
investment company. Each series of Market Street Fund shares represents an
interest in a separate portfolio within the Fund. They are purchased and
redeemed by the corresponding Subaccounts of the Separate Account. The Market
Street Fund sells and redeems its shares at net asset value without a sales
charge.

         The investment objectives of the Market Street Fund's Portfolios you
may choose for your Policy are set forth below. The investment experience of
each of the Subaccounts of the Separate Account 

                                       13

<PAGE>   128

depends on the investment performance of the corresponding Portfolio. There is
no assurance that any Portfolio will achieve its stated objective.

         The Growth Portfolio. The Growth Portfolio seeks intermediate and
long-term growth of capital. A reasonable level of income is an important
secondary objective. This Portfolio pursues its objectives by investing
primarily in common stocks of companies believed to offer above-average growth
potential over both the intermediate and the long term.

         The Sentinel Growth Portfolio. The Sentinel Growth Portfolio seeks
long-term growth of capital through equity participation in companies having
growth potential believed by its investment adviser to be more favorable than
the U.S. economy as a whole, with a focus on relatively well-established
companies.

         The Aggressive Growth Portfolio. The Aggressive Growth Portfolio seeks
to achieve a high level of long-term capital appreciation by investing in
securities of a diverse group of smaller emerging companies.

         The Bond Portfolio. The Bond Portfolio seeks to generate a high level
of current income consistent with prudent investment risk by investing in a
diversified portfolio of marketable debt securities.

         The Managed Portfolio. The Managed Portfolio seeks to realize as high a
level of long-term total rate of return as is consistent with prudent investment
risk by investing in stocks, bonds, money market instruments or a combination
thereof.

         The International Portfolio. The International Portfolio seeks
long-term growth of capital principally through investments in a diversified
portfolio of marketable equity securities of established non-United States
companies.

         The Money Market Portfolio. The Money Market Portfolio seeks to provide
maximum current income consistent with capital preservation and liquidity by
investing in high-quality money market instruments.

         Sentinel Advisors Company ("SAC") manages the Growth, Sentinel Growth,
Aggressive Growth, Bond, Managed and Money Market Portfolios. SAC is registered
as an investment adviser under the Investment Advisers Act of 1940. SAC is a
partnership whose partners are affiliates of National Life, Provident Mutual
Life Insurance Company ("Provident Mutual"), and The Penn Mutual Life Insurance
Company. National Life's affiliate is currently the managing partner of SAC and
is entitled to the majority share of SAC's profit or loss. The International
Portfolio is advised by Providentmutual Investment Management Company ("PIMC"),
which is also registered with the SEC as an investment adviser under the
Investment Advisers Act of 1940. PIMC has employed The Boston Company Asset
Management, Inc. to provide investment advisory services to the International
Portfolio.

         A full description of the Market Street Fund, its investment objectives
and policies, its risks, expenses, and other aspects of its operation is
contained in the attached Prospectus for the Market Street Fund, which you
should read together with this Prospectus.

      The Separate Account has four Subaccounts which invest exclusively in
shares of Portfolios of the Variable Insurance Products Fund (the "VIP Fund")
and two Subaccounts which invest exclusively in shares of Portfolios of the
Variable Insurance Products Fund II ("VIP Fund II"). Like the Market Street
Fund, the VIP Fund and the VIP II Fund are "series" type mutual funds registered

number of series or classes of shares, each of which represents an interest in a
Portfolio of the VIP Fund or VIP Fund II. Shares of these Portfolios are
purchased and redeemed by the Separate Account at net asset value without a
sales charge.

   
         The Equity-Income, Growth, High Income, and Overseas Portfolios of the 
VIP Fund and the Index 500 and Contrafund Portfolios of the VIP Fund II are 
managed by Fidelity Management and Research Company ("FMR"). Bankers Trust 
Company currently serves as sub-advisor to the Index 500 Portfolio. FMR has 
entered into sub-advisory agreements with FMR U.K., FMR Far East, and Fidelity 
International Investment Advisors for the Overseas Portfolio.
    

      The investment objectives of the Portfolios of the VIP Fund and the VIP
Fund II in which the Subaccounts invest are set forth below. The investment
experience of each Subaccount depends upon the investment performance of the
corresponding Portfolio. There is no assurance that any Portfolio will achieve
its stated objective.

   
     Equity-Income Portfolio. This Portfolio seeks reasonable income. The
Portfolio will also consider the potential for capital appreciation. The
Portfolio seeks a yield which exceeds the composite yield of the securities

income-producing equity securities.

while also considering growth of capital. FMR normally invests at least 65% of

is described in the attached Prospectus for the VIP Fund, which should be read
carefully before investing.
    

   
     Overseas Portfolio. This Portfolio seeks long term growth of capital. FMR
normally invests at least 65% of the Portfolio's total assets in foreign
securities. FMR normally invests the Portfolio's assets primarily in common

     Index 500 Portfolio. This Portfolio seeks investment results that
correspond to the total return of common stocks publicly traded in the United
States, as represented by the S&P 500. Bankers Trust Company normally invests at
least 80% of the Portfolio's assets in common stocks included in the S&P 500.
    

   
     Contrafund Portfolio. This Portfolio seeks long-term capital appreciation.
FMR normally invests the Portfolio's assets primarily in common stocks. FMR

objectives and policies of the Portfolios, the risks, expenses and other aspects
of their operation is contained in the attached Prospectuses for the VIP Fund

OTHER INFORMATION

      Contractual Arrangements. We have entered into or may enter into
agreements with Funds pursuant to which the advisor or distributor pays us a fee
based upon an annual percentage of the average net asset amount we invest on
behalf of the Separate Account and our other separate accounts. These
percentages may differ, and we may be paid a greater percentage by some
investment advisors or distributors than other advisors or distributors. These
agreements reflect administrative services provided by us.

      Investment Results. The investment objectives and policies of certain
Portfolios are similar to the investment objectives and policies of mutual fund
portfolios other than the Portfolios that may be managed by the investment
adviser or manager. The investment results of the Portfolios, however, may be
higher or lower than the results of such other portfolios. There can be no
assurance, and no representation is made, that the investment results of any of
the Funds will be comparable to the investment results of any other portfolio,
even if the other portfolio has the same investment adviser or manager.

      Resolving Material Conflicts. The participation agreements under which the
Funds sell their shares to Subaccounts of the Separate Account contain varying
termination provisions. In general, each party may terminate at its option with
specified advance written notice, and may also terminate in the event of
specific regulatory or business developments.

            Should an agreement between National Life and a Fund terminate, the
      Subaccounts which invest in that Fund may not be able to purchase
      additional shares of such Fund. In that event, you will no longer be able
      to transfer Accumulated Values or allocate Net Premiums to Subaccounts
      investing in Portfolios of such Fund.

            Additionally, in certain circumstances, it is possible that a Fund
      or a Portfolio of a Fund may refuse to sell its shares to a Subaccount
      despite the fact that the participation agreement between the Fund and us
      has not been terminated. Should a Fund or Portfolio of such Fund decide
      not to sell its shares to us, we will not be able to honor your requests
      to allocate cash values or net premiums to Subaccounts investing in shares
      of that Fund or Portfolio.

            The Funds are available to registered separate accounts of insurance
      companies, other than National Life, offering variable annuity and
      variable life insurance policies. As a result, there is a possibility that
      a material conflict may arise between the interests of Owners with
      Accumulated Value allocated to the Separate Account and the owners of life
      insurance policies and variable annuities issued by such other 


                                       19
<PAGE>   134

      companies whose values are allocated to one or more other separate
      accounts investing in any one of the Funds.

            In the event of a material conflict, we will take any necessary
      steps, including removing the Separate Account from that Fund, to resolve
      the matter. The Board of Directors or Trustees of the Funds intend to
      monitor events in order to identify any material conflicts that possibly
      may arise and to determine what action, if any, should be taken in
      response to those events or conflicts. See the individual Fund
      Prospectuses for more information.

   
Net Investment Return of the Separate Account. The chart below is included to
comply with Part 54, Section 54.9 of the Codes, Rules and Regulations of the
State of New York. The chart shows the year-by-year net investment returns of
the Subaccounts of the Separate Account since the inception of the Subaccounts
through December 31, 1998. With respect to the Subaccounts of the Market
Street Fund, the Variable Insurance Products Fund, the Variable Insurance
Products Fund II and the Alger American Fund, the inception date of the
Subaccounts is March 13, 1996, the date that the Policies were first offered.
With respect to the Subaccounts of the American Century Variable Portfolios,
Inc., the Goldman Sachs Variable Insurance Trust, the J.P. Morgan Series Trust
II, the Neuberger Berman Advisers Management Trust, the Strong Variable
Insurance Funds, Inc. and the Strong Opportunity Fund II, Inc., the inception
date of the Subaccounts is August 3, 1998.
    

   
      The net investment returns reflect investment income and capital gains
and losses less investment management fees and expenses and the Mortality and
Expense Risk Charge. The returns do not reflect the Cost of Insurance Charge,
the Premium Tax Charge, the Monthly Administrative Charge, the charge for any
optional benefits, or potential Surrender Charges which will significantly
reduce the returns.
    

   
Returns are not annualized for periods under one year.

                    DETAILED DESCRIPTION OF POLICY PROVISIONS

  DEATH BENEFIT

   
            General. As long as the Policy remains in force, we will pay the
      Death Benefit of the Policy, after due proof of the Insured's death (and
      fulfillment of certain other requirements), to the named Beneficiary,
      unless the claim is contestable in accordance with the terms of the
      Policy. You may choose to have the proceeds paid in cash or under one of
      the available Settlement Options. (See "Payment of Policy Benefits," Page
      .) The Death Benefit payable will be the Unadjusted Death Benefit under
      the Death Benefit Option that is in effect, increased by any additional
      benefits, and decreased by any outstanding Policy loan and accrued 
      interest and any unpaid Monthly Deductions.
    

            Death Benefit Options. The Policy provides two Death Benefit
      Options: Option A and Option B. You select the Death Benefit Option in the
      application and may change it as described in "Change in Death Benefit
      Option," Page .

            Option A. The Unadjusted Death Benefit is equal to the greater of:

(a) the Face Amount of the Policy, and

   
(b) the Accumulated Value multiplied by the specified percentage shown in the
table below:
    

<TABLE>
<CAPTION>
         Attained Age         Percentage                      Attained Age      Percentage
         ------------         ----------                      ------------      ----------
<S>                           <C>                             <C>               <C>
         40 and under         250%                            60                130%
            45                215%                            65                120%
            50                185%                            70                115%
            55                150%                            75  and over      105%
</TABLE>

For Attained Ages not shown, the percentages will decrease by a ratable portion
of each full year.

      Illustration of Option A -- For purposes of this illustration, assume that
the Insured is under Attained Age 40 and there is no Policy loan outstanding.

   
      Under Option A, a Policy with a Face Amount of $200,000 will generally
have an Unadjusted Death Benefit of $200,000. The specified percentage for an
Insured under Attained Age 40 on the Policy Anniversary prior to the date of
death is 250%. Because the Unadjusted Death Benefit must be equal to or greater
than 2.50 times the Accumulated Value, any time the Accumulated Value exceeds
$80,000 the Unadjusted Death Benefit will exceed the Face Amount. Each
additional dollar added to the Accumulated Value will increase the Unadjusted
Death Benefit by $2.50. Thus, a 35 year old Insured with an 
    


                                       20
<PAGE>   135

Accumulated Value of $90,000 will have an Unadjusted Death Benefit of $225,000
(2.50 x $90,000, and an Accumulated Value of $150,000 will have an Unadjusted
Death Benefit of $375,000 (2.50 x $150,000).

      Similarly, any time the Accumulated Value exceeds $80,000, each dollar
taken out of the Accumulated Value will reduce the Unadjusted Death Benefit by
$2.50. If at any time, however, the Accumulated Value multiplied by the
specified percentage is less than the Face Amount, the Unadjusted Death Benefit
will be the Face Amount of the Policy.

      Option B. The Unadjusted Death Benefit is equal to the greater of:

(a) the Face Amount of the Policy plus the Accumulated Value, and

   
(b) the Accumulated Value multiplied by the specified percentage shown in the
table above.
    

      Illustration of Option B -- For purposes of this illustration, assume that
the Insured is under Attained Age 40 and there is no Policy loan outstanding.

   
      Under Option B, a Policy with a face amount of $200,000 will generally
have an Unadjusted Death Benefit of $200,000 plus the Accumulated Value. Thus,
for example, a Policy with a $50,000 Accumulated Value will have an Unadjusted
Death Benefit of $250,000 ($200,000 plus $50,000). Since the specified
percentage is 250%, the Unadjusted Death Benefit will be at least 2.50 times the
Accumulated Value. As a result, if the Accumulated Value exceeds $133,333, the
Unadjusted Death Benefit will be greater than the Face Amount plus the
Accumulated Value. Each additional dollar added to the Accumulated Value above
$133,333 will increase the Unadjusted Death Benefit by $2.50. An Insured with an
Accumulated Value of $150,000 will have an Unadjusted Death Benefit of $375,000
(2.50 x $150,000), and an Accumulated Value of $200,000 will yield an Unadjusted
Death Benefit of $500,000 (2.50 x $200,000). Similarly, any time the Accumulated
Value exceeds $133,333, each dollar taken out of the Accumulated Value will
reduce the Unadjusted Death Benefit by $2.50. If at any time, however, the
Accumulated Value multiplied by the specified percentage is less than the Face
Amount plus the Accumulated Value, the Unadjusted Death Benefit will be the Face
Amount plus the Accumulated Value.
    

      Which Death Benefit Option to Choose. If you prefer to have premium
payments and favorable investment performance reflected partly in the form of an
increasing Death Benefit, you should choose Option B. If you are satisfied with
the amount of the Insured's existing insurance coverage and prefer to have
premium payments and favorable investment performance reflected to the maximum
extent in the Accumulated Value, you should choose Option A.

      Change in Death Benefit Option. After the first Policy Year, you may
change the Death Benefit Option in effect by sending us a written request. There
is no charge to change the Death Benefit Option. The effective date of a change
will be the Monthly Policy Date on or next following the date we receive the
written request. Only one change in Death Benefit Option is permitted in any one
Policy Year.

   
        On the effective date of a change in Death Benefit Option, the Face
Amount is adjusted so that there will be no change in the Death Benefit or the
Net Amount at Risk. In the case of a change from Option B to Option A, the Face
Amount must be increased by the Accumulated Value. In the case of a change from
Option A to Option B, the Face Amount must be decreased by the Accumulated
Value. The change from Option A to Option B will not be allowed if it would
reduce the Face Amount to less than the Minimum Face Amount.
    

   
On the effective date of the change, the Death Benefit, Accumulated Value and
Net Amount at Risk (and therefore the Cost of Insurance Charges) are unchanged.
However, after the effective date of the change, the pattern of future Death
Benefits, Accumulated Value, Net Amount at Risk and Cost of Insurance Charges
will be different than if the change had not been made. In determining whether a
change is appropriate for you, the considerations described in "Which Death
Benefit Option to Choose" above will apply.
    


   
    

   
    

   
    



                                       21
<PAGE>   136
   
    

   
    

   
    

      If a change in the Death Benefit Option would result in cumulative
premiums exceeding the maximum premium limitations under the Internal Revenue
Code for life insurance, we will not effect the change.

      A change in the Death Benefit Option may have Federal income tax
consequences. (See "Tax Treatment of Policy Benefits," Page .)

      How the Death Benefit May Vary. The amount of the Death Benefit may vary
with the Accumulated Value. The Death Benefit under Option A will vary with the
Accumulated Value whenever the specified percentage of Accumulated Value exceeds
the Face Amount of the Policy. The Death Benefit under Option B will always vary
with the Accumulated Value because the Unadjusted Death Benefit equals the
greater of (a) the Face Amount plus the Accumulated Value and (b) the
Accumulated Value multiplied by the specified percentage.

ABILITY TO ADJUST FACE AMOUNT

   
        You may, at any time after the first Policy Year, increase or decrease
the Policy's Face Amount by submitting a written application to us. There are
some limits on your ability to effect increases or decreases, which are
discussed below. The effective date of an increase will be the Monthly Policy
Date on or next following our approval of your request. The effective date of a
decrease is the Monthly Policy Date on or next following the date that we
receive your written request. Employee benefit plan Policies may adjust the Face
Amount even in Policy Year 1. An increase or decrease in Face Amount may have
federal tax consequences. (See "Tax Treatment Of Policy Benefits," Page .) The
effect of changes in Face Amount on Policy charges, as well as other
considerations, are described below.
    

        Increase. A request for an increase in Face Amount may not be for less
  than $25,000, or such lesser amount required in a particular state (except
  that the minimum for employee benefit plans is $2000). You may not increase
  the Face Amount after the Insured's Attained Age 85. To obtain the increase,
  you must submit an application for the increase and provide evidence
  satisfactory to us of the Insured's insurability.

        On the effective date of an increase, and taking the increase into
  account, the Cash Surrender Value must be at least equal to the Monthly
  Deductions then due. If the Cash Surrender Value is not sufficient, 


                                       22
<PAGE>   137

  the increase will not take effect until you pay a sufficient additional
  premium payment to increase the Cash Surrender Value.

        An increase in the Face Amount will generally affect the total Net
  Amount at Risk. This will normally increase the monthly Cost of Insurance
  Charges. In addition, the Insured may be in a different Rate Class as to the
  increase in insurance coverage. An increase in premium payment or frequency
  may be appropriate after an increase in Face Amount. (See "Cost of Insurance
  Charge," Page .)

   
         Decrease. The amount of the Face Amount after a decrease cannot be less
  than 75% of the largest Face Amount in force at any time in the twelve months
  immediately preceding our receipt of your request for the decrease. The Face
  Amount after any decrease may not be less than the Minimum Face Amount, which
  is generally currently $50,000. If a decrease in the Face Amount would result
  in cumulative premiums exceeding the maximum premium limitations applicable
  for life insurance under the Internal Revenue Code, we will not allow the
  decrease.
    

        A decrease in the Face Amount generally will decrease the total Net
  Amount at Risk, which will decrease your monthly Cost of Insurance Charges.

        For purposes of determining the Cost of Insurance Charge, any decrease
  in the Face Amount will reduce the Face Amount in the following order:

            (a)   first, the increase in Face Amount provided by the most recent
                  increase;

            (b)   then the next most recent increases, in inverse chronological
                  order; and finally

            (c)   the Initial Face Amount.

HOW THE DURATION OF THE POLICY MAY VARY

         Your Policy will remain in force as long as the Cash Surrender Value of
the Policy is sufficient to pay the Monthly Deductions and the charges under the
Policy. When the Cash Surrender Value is insufficient to pay the charges and the
Grace Period expires without an adequate premium payment by you, the Policy will
lapse and terminate without value. However, during the first five Policy Years
the Policy will not lapse, if you have paid the Minimum Guarantee Premium. You
have certain rights to reinstate your Policy, if it should lapse. (See
"Reinstatement," Page .)

          In addition, an optional Guaranteed Death Benefit Rider is available
which will guarantee that the Policy will not lapse prior to age 70, or 20 years
from the Date of Issue of the Policy, if longer, regardless of investment
performance, if you have paid the Minimum Guarantee Premium as of each Monthly
Policy Date.

ACCUMULATED VALUE

         The Accumulated Value is the total amount of value held under the
Policy at any time. It is equal to the sum of the Policy's values in the
Separate Account and the General Account. The Accumulated Value minus any
applicable Surrender Charge, and minus any outstanding Policy loans and accrued
interest, is equal to the Cash Surrender Value. There is no guaranteed minimum
for the portion of the Accumulated Value in any of the Subaccounts of the
Separate Account. Because the Accumulated Value on any future date depends upon
a number of variables, it cannot be predetermined.

         The Accumulated Value and Cash Surrender Value will reflect:

    -    the Net Premiums paid

    -    the investment performance of the Portfolios you have chosen

    -    the crediting of interest on non-loaned Accumulated Value in the 
         General Account and amounts held as Collateral in the General Account


                                       23
<PAGE>   138

    -    any transfers

    -    any Withdrawals

    -    any loans

    -    any loan repayments

   
    -    any loan interest charged, and
    

    -    charges assessed on the Policy.

         Determination of Number of Units for the Separate Account. Amounts
allocated, transferred or added to a Subaccount of the Separate Account under a
Policy are used to purchase units of that Subaccount; units are redeemed when
amounts are deducted, transferred or withdrawn. The number of units a Policy has
in a Subaccount equals the number of units purchased minus the number of units
redeemed up to such time. For each Subaccount, the number of units purchased or
redeemed in connection with a particular transaction is determined by dividing
the dollar amount by the unit value.

         Determination of Unit Value. The unit value of a Subaccount is equal to
the unit value on the immediately preceding Valuation Day multiplied by the Net
Investment Factor for that Subaccount on that Valuation Day.

         Net Investment Factor. Each Subaccount of the Separate Account has its
own Net Investment Factor. The Net Investment Factor measures the daily
investment performance of the Subaccount. The factor will increase or decrease,
as appropriate, to reflect net investment income and capital gains or losses,
realized and unrealized, for the securities of the underlying portfolio or
series.

         The asset charge for mortality and expense risks will be deducted in
determining the applicable Net Investment Factor. (See "Charges and Deductions -
Mortality and Expense Risk Charge," Page   .)

         Calculation of Accumulated Value. The Accumulated Value is determined
first on the Date of Issue and thereafter on each Valuation Day. On the Date of
Issue, the Accumulated Value will be the Net Premiums received, plus any
earnings prior to the Date of Issue, less any Monthly Deductions due on the Date
of Issue. On each Valuation Day after the Date of Issue, the Accumulated Value
will be:

         (1)   The aggregate of the values attributable to the Policy in the
               Separate Account, determined by multiplying the number of units 
               the Policy has in each Subaccount of the Separate Account by such
               Subaccount's unit value on that date; plus

         (2)   The value attributable to the Policy in the General Account 
               (See "The General Account," Page.)

PAYMENT AND ALLOCATION OF PREMIUMS

   
         Issuance of a Policy. To purchase a Policy, you must apply to us
  through a licensed National Life agent who is also a registered representative
  of Equity Services, Inc. ("ESI") or a broker/dealer having a Selling Agreement
  with ESI. If you do not pay the Minimum Initial Premium with your written
  application, it must be paid when the Policy is delivered.  If the premium
  paid is less than the Minimum Initial Premium, the balance of the Minimum
  Initial Premium must be received within five days, or all premiums will be
  refunded.
    

        The Minimum Face Amount of a Policy under our rules is generally
  $50,000; however, exceptions may be made for employee benefit plans. We may
  revise our rules from time to time to specify a different Minimum Face Amount
  for subsequently issued policies. A Policy will be issued only on Insureds who
  have an Issue Age of 85 or less and who provide us with satisfactory evidence
  of 


                                       24
<PAGE>   139

  insurability. Acceptance is subject to our underwriting rules. We may
  reject an application for any reason permitted by law. (See "Distribution of
  Policies," Page .)

   
         From the time the application for a Policy is signed until the time the
  Policy is issued, you can, subject to our underwriting rules, obtain temporary
  insurance protection, pending issuance of the Policy, if you are able to
  answer "no" to the Health Questions of the Receipt & Temporary Life Insurance
  Agreement and submitting (a) a complete Application including any medical
  questionnaire required, and (b) payment of the Minimum Initial Premium. 
    

         The amount of coverage under the Receipt & Temporary Life Insurance
  Agreement is the lesser of the Face Amount applied for or $1,000,000 ($100,000
  in the case of proposed Insureds age 70 or over). Coverage under the agreement
  will end on the earliest of:

  (a) the 90th day from the date of the agreement; 
  (b) the date that insurance takes effect under the Policy; 
  (c) the date a policy, other than as applied for, is offered to you; 
  (d) five days from the date we mail a notice of termination of coverage;
  (e) the time you first learn that we have terminated the temporary life
      insurance; or 
  (f) the time you withdraw the application for life insurance.

         We offer a one time credit on conversions of eligible National Life
term insurance policies to a VariTrak Policy. If the term policy being converted
has been in force for at least twelve months, the amount of the credit is 12% of
a target amount used to determine commission payments. If the term policy being
converted has been in force for less than twelve months, the credit will be
prorated based on the number of months the term policy has been outstanding at
the time of conversion. For GRT term policies, the credit will be 18% of the
target amount used to determine commission payments if the GRT term policy has
been in force for at least two years but not more than five years. For GRT term
policies in force for less than two years, the credit is 0.5% per month for each
month in the first year, and 1.0% per month for each month in the second year.
For GRT policies in force more than five years, the credit decreases from 18% by
0.5% for each month beyond five years, until it becomes zero at the end of year
eight.

         The amount of the credit will be added to the initial premium payment,
if any, you pay and will be treated as part of the Initial Premium for the
Policy. Thus, the credit will be included in premium payments for purposes of
calculating and deducting the Premium Tax Charge. If you surrender your Policy,
we will not recapture the credit. We will not include the amount of the credit
for purposes of calculating agent compensation for the sale of the Policy.

         We also offer a one time credit to Home Office employees who purchase a
VariTrak Policy, as both Owner and Insured. This one time credit is calculated
differently from the credit described above; in particular, the amount of the
credit will be 50% of the target premium used in the calculation of commissions
on the Policy. Otherwise, the credit will be treated in the same manner as the
credit described above.

         Amount and Timing of Premiums. Each premium payment must be at least
  $50. You have considerable flexibility in determining the amount and frequency
  of premium payments, within the limits discussed below.

   
         You will at the time of application select a Planned Periodic Premium
  schedule, based on a periodic billing mode of annual, semi-annual, or
  quarterly payments. You may request us to send a premium reminder notice at
  the specified interval. You may change the Planned Periodic Premium frequency
  and amount. Also, under an Automatic Payment Plan plan, you can select a
  monthly payment schedule pursuant to which premium payments will be
  automatically deducted from a bank account or other source, rather than being
  "billed." We may allow, in certain situations, Automatic Payment Plan payments
  of less than $50. We may require that Automatic Payment Plans be set up for at
  least the Minimum Monthly Premium.

         You are not required to pay the Planned Periodic Premiums in accordance
  with the specified schedule. You may pay premiums whenever you like, and in
  any amount (subject to the $50 minimum and the limitations described in the
  next section). Payment of the Planned Periodic Premiums will not, however,
  guarantee that the Policy will remain in force. Instead, the duration of the
  Policy depends upon the Policy's Cash Surrender Value. Thus, even if you pay
  the Planned Periodic Premiums, the Policy will lapse whenever the Cash
  Surrender Value is insufficient to pay the Monthly Deductions and any other
  charges under the Policy and if a Grace Period expires without an adequate
  payment by you (unless the Policy is in its first five years, or you have
  purchased the Guaranteed Death Benefit Rider, in either case so long as you
  have paid the Minimum Guarantee Premium).

        Any payments you make while there is an outstanding Policy loan will be
applied as premium payments rather than loan repayments, unless you notify us in
writing that the amount is to be applied as a loan repayment.

         Higher premium payments under Death Benefit Option A, until the
applicable percentage of Accumulated Value exceeds the Face Amount, will
generally result in a lower Net Amount at Risk. This will produce lower Cost of
Insurance Charges against the Policy. Conversely, lower premium payments in this
situation will result in a higher Net Amount at Risk, which will result in
higher Cost of Insurance Charges under the Policy.

         Under Death Benefit Option B, until the applicable percentage of
Accumulated Value exceeds the Face Amount plus the Accumulated Value, the level
of premium payments will not affect the Net Amount at Risk. However, both the
Accumulated Value and Death Benefit will be higher if premium payments are
higher, and lower if premium payments are lower.

         Under either Death Benefit Option, if the Unadjusted Death Benefit is
the applicable percentage of Accumulated Value, then higher premium payments
will result in a higher Net Amount at Risk, and higher Cost of Insurance
Charges. Lower premium payments will result in a lower Net Amount at Risk, and
lower Cost of Insurance Charges.

   
         Premium Limitations. The Internal Revenue Code of 1986 (the "Code")
  provides for exclusion of the Death Benefit from gross income if total premium
  payments do not exceed certain stated limits. In no event can the total of all
  premiums paid under a Policy exceed these limits. If at any time you pay a
  premium which would result in total premiums exceeding the limits, we will
  only accept that portion of the premium which would make total premiums equal
  the maximum amount which may be paid under the Policy. We will promptly refund
  the excess to you. In cases of premiums paid by check, we will wait until your
  check has cleared. If you have an outstanding loan, we may instead apply the
  payment as a loan repayment. Even if total premiums were to exceed the maximum
  premium limitations established by the Code, the excess of (a) a Policy's
  Unadjusted Death Benefit over (b) the Policy's Cash Surrender Value plus
  outstanding Policy loans and accrued interest, would still be excludable from
  gross income under the Code.
    

         The maximum premium limitations set forth in the Code depend in part
  upon the amount of the Unadjusted Death Benefit at any time. As a result, any
  Policy changes which affect the amount of the Unadjusted Death Benefit may
  affect whether cumulative premiums paid under the Policy exceed the maximum
  premium limitations. To the extent that any such change would result in
  cumulative premiums exceeding the maximum premium limitations, we will not
  effect the change. (See "Federal Income Tax Considerations," Page .)

         Unless the Insured provides satisfactory evidence of insurability, we
  may limit the amount of any premium payment if it increases the Unadjusted
  Death Benefit more than it increases the Accumulated Value.

         Allocation of Net Premiums. The Net Premium equals the premium paid
  less the Premium Tax Charge. In your application for the Policy, you will
  indicate how Net Premiums should be allocated among the Subaccounts of the
  Separate Account and/or the General Account. You may change these


                                       26
<PAGE>   141

  allocations at any time by giving us written notice at our Home Office, or
  if you have elected the telephone transaction privilege, by telephone
  instructions (See "Telephone Transaction Privilege," Page .) You must make
  allocations in whole number percentages of at least 5%, and the sum of the
  allocation percentages must be 100%. We will allocate Net Premiums as of
  the Valuation Date we receive the premium at our Home Office, based on the
  allocation percentages then in effect, except during the free look period.

         We will allocate any portion of the Initial Premium and any subsequent
  premiums we receive before the end of the free look period which are to be
  allocated to the Separate Account, to the Money Market Subaccount. For this
  purpose, we will assume that the free look period will end 20 days after the
  date the Policy is issued. On the first Valuation Date following 20 days after
  issue of the Policy, we will allocate the amount in the Money Market
  Subaccount to each of the Subaccounts selected in the application based on
  your instructions.

         For example, assume a Policy was issued with Net Premiums to be
  allocated 25% to the Managed Subaccount, 25% to the Bond Subaccount and 50% to
  the General Account. During the period stated above, 50% (25% + 25%) of the
  Net Premiums will be allocated to the Money Market Subaccount. At the end of
  such period, 50% (25% / 50%) of the amount in the Money Market Subaccount will
  be transferred to the Managed Subaccount and 50% to the Bond Subaccount.

         The values of the Subaccounts will vary with their investment
  experience. You bear the entire investment risk. You should periodically
  review your allocation percentages in light of market conditions and your
  overall financial objectives.

         Transfers. You may transfer the Accumulated Value between and among the
Subaccounts of the Separate Account and the General Account by sending us a
written transfer request, or if you have elected the telephone transaction
privilege, by telephone instructions to us. (See "Telephone Transaction
Privilege," Page .) Transfers between and among the Subaccounts of the Separate
Account and the General Account are made as of the Valuation Day that the
request for transfer is received at the Home Office. You may, at any time,
transfer all or part of the amount in one of the Subaccounts of the Separate
Account to another Subaccount and/or to the General Account. For transfers from
the General Account to the Separate Account, see "Transfers from General
Account," Page .

         Currently an unlimited number of transfers are permitted without
charge. We have no current intent to impose a transfer charge in the foreseeable
future. However, we may, after giving you prior notice, change this policy so as
to deduct a $25 transfer charge from each transfer in excess of the twelfth
transfer during any one Policy Year. All transfers requested during one
Valuation Period are treated as one transfer transaction. If a transfer charge
is adopted in the future, these types of transfers would not be subject to a
transfer charge and would not count against the twelve free transfers in any
Policy Year:

    -    transfers resulting from Policy loans

    -    transfers resulting from the operation of the dollar cost averaging or
         portfolio rebalancing features 

    -    transfers resulting from the exercise of the transfer rights 
         described on page____ (see "Policy Rights - Other Transfer Rights,"
         Page    ), and 

    -    the reallocation from the Money Market Subaccount following the free 
         look period.

Under present law, transfers are not taxable transactions.

         Policy Lapse. The failure to make a premium payment will not itself
cause a Policy to lapse. A Policy will lapse only when the Cash Surrender Value
is insufficient to cover the Monthly Deductions and other charges under the
Policy and the Grace Period expires without a sufficient payment. During the
first five Policy Years, the Policy will not lapse so long as you pay the
Minimum Guarantee Premium.

      In addition, if you purchase the Guaranteed Death Benefit Rider, and pay
the Minimum Guarantee Premium as of each Monthly Policy Date, your Policy will
not lapse prior to the Insured's Attained Age 


                                       27
<PAGE>   142
   
70, or 20 years from the Date of Issue of the Policy if longer, regardless of
whether the Cash Surrender Value is sufficient to cover the Monthly Deductions.
If you purchase the Guaranteed Death Benefit Rider, your Minimum Guarantee
Premium will be higher than if you do not purchase the Guaranteed Death Benefit
Rider. (See "Optional Benefits - Guaranteed Death Benefit," Page .) 
    

         The Policy provides for a 61-day Grace Period that is measured from the
date we send a lapse notice. The Policy does not lapse, and the insurance
coverage continues, until the expiration of this Grace Period. To prevent lapse,
you must during the Grace Period pay a premium equal to the sum of any amount by
which the past Monthly Deductions have been in excess of Cash Surrender Value,
plus three times the Monthly Deduction due the date the Grace Period began. Our
notice will specify the payment required to keep the Policy in force. Failure to
make a payment at least equal to the required amount within the Grace Period
will result in lapse of the Policy without value.

         Reinstatement. A Policy that lapses without value may be reinstated at
any time within five years (or longer period required in a particular state)
after the beginning of the Grace Period. To do so, you must submit evidence of
the Insured's insurability satisfactory to us and pay an amount sufficient to
provide for two times the Monthly Deduction due on the date the Grace Period
began plus three times the Monthly Deduction due on the effective date of
reinstatement. The effective date of reinstatement, unless otherwise required by
state law, will be the Monthly Policy Date on or next following the date your
reinstatement application is approved. Upon reinstatement, the Accumulated Value
will be based upon the premium paid to reinstate the Policy. The Policy will be
reinstated with the same Date of Issue as it had prior to the lapse. Neither the
five year no lapse guarantee nor the Death Benefit Guarantee Rider may be
reinstated.

      Specialized Uses of the Policy. Because the Policy provides for an
accumulation of cash value as well as a death benefit, the Policy can be used
for various individual and business financial planning purposes. Purchasing the
Policy in part for such purposes entails certain risks. For example, if the
investment performance of the chosen Subaccounts is poorer than expected or if
sufficient premiums are not paid, the Policy may lapse or may not accumulate
sufficient Accumulated Value or Cash Surrender Value to fund the purpose for
which the Policy was purchased. Withdrawals and Policy loans may significantly
affect current and future Accumulated Value, Cash Surrender Value, or Death
Benefit proceeds. Depending upon Subaccount investment performance and the
amount of a Policy loan, the loan may cause a Policy to lapse. Because the
Policy is designed to provide benefits on a long-term basis, before purchasing a
Policy for a specialized purpose you should consider whether the long-term
nature of the Policy is consistent with your purpose. Using a Policy for a
specialized purpose may have tax consequences. (See "Federal Income Tax
Considerations," Page .)

      For Policies that are intended to be used in STEP plans, you should be
aware that there is a risk that the intended tax consequences of such a plan may
not be realized. In two audits, the Internal Revenue Service has proposed tax
treatment less advantageous than intended, and those matters are currently in
litigation. The plans under audit may have considerable differences from those
you may be considering, and the litigation regarding such plans may or may not
be controlling with respect to STEP plans you may implement. We do not guarantee
any particular tax consequences of any use of the Policies, including but not
limited to use in STEP plans. We recommend that you seek independent tax advice
with respect to applications in which you seek particular tax consequences.

                             CHARGES AND DEDUCTIONS

      Charges will be deducted in connection with the Policy to compensate us
for:

      (a) providing the insurance and other benefits set forth in the Policy;

      (b) administering the Policy;

      (c) assuming certain mortality and other risks in connection with the 
          Policy; and

      (d) incurring expenses in distributing the Policy including costs
          associated with printing prospectuses and sales literature and sales
          compensation.

      We may realize a profit from any charges. We may use any profit for any
purpose, including payment of distribution expenses.

PREMIUM TAX CHARGE

      We will deduct 3.25% from each premium payment prior to allocation of Net
Premiums, to cover state premium taxes and the federal DAC Tax. For qualified
employee benefit plans, we will deduct 2.0% of each premium rather than 3.25%.

      The federal DAC Tax is a tax attributable to certain "policy acquisition
expenses" under Internal Revenue Code Section 848. Section 848 in effect
accelerates the realization of income we receive from the Policies, and
therefore the payment of federal income taxes on that income. The economic
consequence of Section 848 is, therefore, an increase in the tax burden borne by
us that is attributable to the Policies.

SURRENDER CHARGE

      We impose a Surrender Charge, which consists of a Deferred Administrative
Charge and a Deferred Sales Charge, if the Policy is surrendered or lapses at
any time before the end of the fifteenth Policy Year.

      Deferred Administrative Charge. The Deferred Administrative Charge varies
by Issue Age, and is based on the Initial Face Amount. After the first five
Policy Years, it declines linearly by Policy Month until the end of Policy Year
15, when it becomes zero. Charges per $1,000 of Face Amount for sample Issue
Ages are shown below:

<TABLE>
<CAPTION>
          Sample                             Charge per $1000
          Issue Age                          of Initial Face Amount
          ---------                          ----------------------
<S>                                          <C>

          10                                          $0.50
          15                                          $1.00
          20                                          $1.50
          25-85                                       $2.00
</TABLE>

        For Issue Ages not shown, the charge will increase by a ratable portion
  for each full year. The Deferred Administrative Charge has been designed to
  cover actual expenses for the issue and underwriting of Policies, and is not
  intended to produce a profit.

   
        Deferred Sales Charge. The Deferred Sales Charge will not exceed the
  Maximum Deferred Sales Charge specified in the Policy. 
    


                                       29
<PAGE>   144

   
    
            The actual Deferred Sales Charge will equal the lesser of:

      (a)   the maximum discussed in the previous paragraph, and

      (b)   an amount equal to the sum of:

            (i)   30% of the premiums actually received up to one Surrender
                  Charge target premium, plus

            (ii)  10% of all premiums paid in excess of this amount but not
                  greater than twice this amount, plus

            (iii) 9% of all premiums paid in excess of twice this amount.

   
            Appendix B to this Prospectus contains a table showing the Surrender
            Charge target premium and the Maximum Deferred Sales Charge for male
            and female nonsmokers of each age at the time a policy is issued, 
            expressed as a dollar amount per $1000 of Initial Face Amount.
    

            To illustrate the calculation of a Policy's Surrender Charge, assume
            that the Policy is issued to a male nonsmoker, Issue Age 45, with a
            Face Amount of $100,000. Assume that the Surrender Charge target
            premium ("SCTP") is $1,652, the initial Maximum Deferred Sales
            Charge is $826 (50% of $1,652) and the Insured pays annual premiums
            of $1,500 at the beginning of each Policy Year. This example will
            illustrate surrenders in the first five Policy Years and in the
            first month of the eighth Policy Year.

            Deferred Administrative Charge. The Deferred Administrative Charge
            for the first five Policy Years is $200. This is calculated by
            applying the charge of $2.00 per $1,000 of Face Amount for Issue Age
            45 from the schedule above to the Face Amount of $100,000 ($2.00 x
            (100,000/1,000)). The Deferred Administrative Charge reduces
            linearly by Policy Month in Policy Years 6 through 15. Linear
            reduction is equivalent to a reduction each month of 1/121st of the
            initial charge. For example, the Deferred Administrative Charge in
            the first month of the eighth Policy Year (the 25th month after the
            end of the 5th Policy Year) will be $158.68 ($200 - ($200 x
            (25/121)). After completion of the 15th Policy Year, the Deferred
            Administrative Charge is zero. The schedule of Deferred
            Administrative Charges in effect for the first fifteen Policy Years
            is shown in the Policy.

            Deferred Sales Charge. The Deferred Sales Charge is the lesser of
            the Maximum Deferred Sales Charge and an amount calculated based on
            the Insured's actual premium payments. The Maximum Deferred Sales
            Charge in effect for the first five Policy Years is $826. The
            Maximum Deferred Sales Charge reduces linearly by month in Policy
            Years 6 through 15. Linear reduction is equivalent to a reduction
            each month of 1/121st of the initial charge. For example, the
            Maximum Deferred Sales Charge in the first month of the 8th Policy
            Year (the 25th month after the end of the 5th Policy Year) will be
            $655.34 ($826 - ($826 x (25/121))). After the completion of the 15th
            Policy Year, the Maximum Deferred Sales Charge is $0. The schedule
            of Maximum Deferred Sales Charges in effect for the first fifteen
            Policy Years is shown in the Policy.

            The Maximum Deferred Sales Charge is compared to an amount
            calculated as a function of premiums actually paid and the SCTP. The
            amount is calculated as the sum of 30% of premiums paid up to the
            first SCTP ($1,652), 10% of premiums paid in excess of the first
            SCTP but not more than two SCTP's (from $1,653 to $3,304), and 9% of
            premiums paid in excess of two SCTP's (above $3,304). As an example,
            the calculated amounts in Policy Years 1 through 5 and Policy Year 8
            would be as follows:

            The total calculated amount would then be compared to the Maximum
            Deferred Sales Charge to determine the Deferred Sales Charge
            actually imposed. For example, the Deferred Sales Charge in the

</TABLE>

            In this example, the charge based on SCTP is less than the Maximum
            Deferred Sales Charge until the fourth Policy Year. Thereafter, the
            Maximum Deferred Sales Charge is less than the charge based on SCTP.
            For example, the Deferred Sales Charge in the first month of the
            eighth Policy Year will be the Maximum Deferred Sales Charge of
            $655.34 (calculated above) since this is less than $1,443.44 (the
            calculated amount based on premiums paid).

MONTHLY DEDUCTIONS

      We will deduct charges from the Accumulated Value on the Date of Issue and
on each Monthly Policy Date. The Monthly Deduction consists of three components:

      (a)   the Cost of Insurance Charge

      (b)   the Monthly Administrative Charge, and

      (c)   the cost of any additional benefits provided by Rider.

      The Monthly Deduction may vary in amount from Policy Month to Policy
Month. We will take the Monthly Deduction on a pro rata basis from the
Subaccounts of the Separate Account and the General Account, unless you have
requested at the time of application, or later request in writing, that we take
the Monthly Deductions from the Money Market Subaccount. If we cannot take a
Monthly Deduction from the Money Market Subaccount, where you have so asked, we
will take the amount of the deduction in excess of the Accumulated Value
available in the Money Market Subaccount on a pro rata basis from Accumulated
Value in the Subaccounts of the Separate Account and the General Account.

      Cost of Insurance Charge. We calculate the monthly Cost of Insurance
Charge by multiplying the applicable cost of insurance rate or rates by the Net
Amount at Risk for each Policy Month. Because both the Net Amount at Risk and
the variables that determine the cost of insurance rate, such as the age of the
Insured and the Duration of the Policy, may vary, the Cost of Insurance Charge
will likely be different from month to month.

            Net Amount at Risk. The Net Amount at Risk on any Monthly Policy
      Date is approximately the amount by which the Unadjusted Death Benefit on
      that Monthly Policy Date exceeds the Accumulated Value. It measures the
      amount National Life would have to pay in excess of the Policy's Value if
      the Insured died. The actual calculation uses the Unadjusted Death Benefit
      divided by 1.00327234, to take into account assumed monthly earnings at an
      annual rate of 4%. We calculate the Net Amount at Risk separately for the
      Initial Face Amount and any increases in Face Amount. In determining the
      Net Amount at Risk for each increment of Face Amount, we first consider
      the Accumulated Value part of the Initial Face Amount. If the Accumulated
      Value exceeds the Initial Face Amount, we consider it as part of any
      increases in Face Amount in the order such increases took effect.


                                       31
<PAGE>   146

            Any change in the Net Amount at Risk will affect the total Cost of
      Insurance Charges paid by the Owner.

            Guaranteed Maximum Cost of Insurance Rates. The guaranteed maximum
      cost of insurance rates will be set forth in your Policy, and will depend
      on:

      -     the Insured's Attained Age

      -     the Insured's sex

      -     the Insured's Rate Class, and

      -     the 1980 Commissioners Standard Ordinary Smoker/Nonsmoker Mortality
            Table.

            For Policies issued in conjunction with employee benefit plans, the
      guaranteed maximum cost of insurance rate will use the 1980 Commissioners
      Standard Ordinary Mortality Tables NB and SB.

            Current Cost of Insurance Rates and How They are Determined. The
      actual cost of insurance rates used ("current rates") will depend on:

      -     the Insured's Issue Age

      -     the Insured's sex

      -     the Insured's Rate Class

      -     the Policy's Duration, and

      -     the Policy's size.

            Generally, the current cost of insurance rate for a given Attained
      Age will be less than for an Insured whose Policy was issued more than 10
      years ago, than for an Insured whose Policy was issued less than 10 years
      ago, other factors being equal. We periodically review the adequacy of our
      current cost of insurance rates and may adjust their level. However, the
      current rates will never exceed guaranteed maximum cost of insurance
      rates. Any change in the current cost of insurance rates will apply to all
      persons of the same Issue Age, sex, and Rate Class, and with Policies of
      the same Duration and size.

   
            We use separate cost of insurance rates for the Initial Face Amount
      and any increases in Face Amount. For the Initial Face Amount we use the
      rate for the Insured's Rate Class on the Date of Issue. For each increase
      in Face Amount, we use the rate for the Insured's Rate Class at the time
      of the increase. If the Unadjusted Death Benefit is calculated as the
      Accumulated Value times the specified percentage, we use the rate for the
      Rate Class for the Initial Face Amount for the amount of the Unadjusted
      Death Benefit in excess of the total Face Amount for Option A, and 
      in excess of the total Face Amount plus the Accumulated Value for 
      Option B.
    

   
    

            Rate Class. The Rate Class of the Insured will affect both the
      guaranteed and current cost of insurance rates. We currently place
      Insureds into the following rate classes:

      -     preferred nonsmoker

      -     standard nonsmoker

      -     smoker

      -     juvenile, and

      -     substandard.

            Smoker, juvenile, and substandard classes reflect higher mortality
      risks. In an otherwise identical Policy, an Insured in a preferred or
      standard class will have a lower Cost of Insurance Charge than an Insured
      in a substandard class with higher mortality risks. Nonsmoking Insureds
      will generally incur lower cost of insurance rates than Insureds who are
      classified as smokers.

            The nonsmoker designation is not available for Insureds under
      Attained Age 20. Shortly before an Insured attains age 20, we will notify
      the Insured about possible classification as a nonsmoker and 


                                       32
<PAGE>   147

   
      direct the Insured to his or her agent to initiate a change in Rate Class.
      If the Insured qualifies as a nonsmoker, we will change the guaranteed
      and current cost of insurance rates to reflect the nonsmoker
      classification.
    

            Current cost of insurance rates will also vary by Policy size, in
      the following bands:

   
      -    those with Face Amounts less than $250,000
    

   
      -    those with Face Amounts between $250,000 and $999,999, inclusive; and
    

   
      -    those with Face Amounts of $1,000,000 and over.
    

           Cost of insurance rates will be lower as the Policy size band is
      larger.

   
     Monthly Administrative Charge. We deduct a Monthly Administrative Charge
from the Accumulated Value on the Date of Issue and each Monthly Policy Date as
part of the Monthly Deduction to help defray the expenses incurred in
administering the Policy. The Monthly Administrative Charge is currently $7.50.
The monthly charge is guaranteed not to exceed $7.50 plus $0.07 per $1000 of
Face Amount.

    

      Optional Benefit Charges. The Monthly Deduction will include charges for
any additional benefits added to the Policy. The monthly charges will be
specified in the applicable Rider. The available Riders are listed under
"Optional Benefits", on Page below.

      Separate Account Enhancement. We will reduce the Monthly Deductions
starting in the eleventh Policy Year by an amount equal to 0.50% per annum of
the Accumulated Value in the Separate Account.

      The separate account enhancement is calculated on each Monthly Policy Date
as .041572% (the monthly equivalent of 0.50% per annum) of the Accumulated Value
in the Separate Account on the just prior Monthly Policy Date. For example, if
the Accumulated Value in the Separate Account on the just prior Monthly Policy
Date is $10,000, then the separate account enhancement calculated for the
current Monthly Policy Date will be $4.16 ($10,000 X .00041572). To calculate
the Monthly Deduction for the current Monthly Policy Date, we net the $4.16
separate account enhancement against the Monthly Deductions for Cost of
Insurance, the Monthly Administrative Charge, and charges for any Optional
Benefits.

MORTALITY AND EXPENSE RISK CHARGE

      We deduct a daily charge from the Separate Account at an annual rate of
0.90% (or a daily rate of .0024548%) of the average daily net assets of each
Subaccount of the Separate Account. This charge compensates us for the mortality
and expense risks assumed in connection with the Policy. The mortality risk we
assume is that insured persons may live for a shorter time than projected. This
means we would pay greater death benefits than expected in relation to the
amount of premiums received. The expense risk we assume is that expenses
incurred in issuing and administering the Policies will exceed the
administrative charges deducted from the Policy. We may make a profit from
deducting this charge. Any profit may be used to finance distribution expenses.

WITHDRAWAL CHARGE

      We will assess on each Withdrawal a charge equal to the lesser of 2% of
the Withdrawal amount and $25. We will deduct this Withdrawal Charge from the
Withdrawal amount.

TRANSFER CHARGE

      Currently, unlimited transfers are permitted among the Subaccounts, or
from the Separate Account to the General Account. Transfers from the General
Account to the Separate Account are permitted within the limits described on
Page . Currently there is no charge for any transfers. We have no present
intention to impose a transfer charge in the foreseeable future. However, we may
impose in the future a 


                                       33
<PAGE>   148

transfer charge of $25 on each transfer in excess of twelve transfers in any
Policy Year. The Transfer Charge would be imposed to compensate us for the costs
of processing such transfers, and would not be designed to produce a profit.

      If we impose a transfer charge in the future, we will deduct it from the
amount being transferred. We would treat all transfers requested on the same
Valuation Date as one transfer transaction. Any future transfer charge will not
apply to transfers resulting from:

      -     Policy loans

      -     the exercise of the transfer rights described on page___

      -     the initial reallocation of account values from the Money Market
            Subaccount to other Subaccounts, and

      -     any transfers made pursuant to the Dollar Cost Averaging and
            Portfolio Rebalancing features.

The transfers listed above also will not count against the twelve free transfers
in any Policy Year.

PROJECTION REPORT CHARGE

      We may impose a charge, not to exceed $25, for each projection report you
request. This report will project future values and future Death Benefits for
the Policy. We will notify you in advance of the amount of the charge. You may
elect to pay the charge in advance. If not paid in advance, we will deduct this
charge from the Subaccounts of the Separate Account and/or the General Account
in proportion to their Accumulated Values on the date of the deduction.

OTHER CHARGES

      The Separate Account purchases shares of the Funds at net asset value. The
net asset value of those shares reflect management fees and expenses already
deducted from the assets of the Funds' Portfolios. Historical expense ratio
information for the Funds is presented in the "Summary of Policy Expenses"
section on page above. More detailed information is contained in the Funds'
Prospectuses which accompany this Prospectus.

                          POLICY RIGHTS AND PRIVILEGES

LOAN PRIVILEGES

   
      General. You may at any time after the first year (and during the first
year where required by law) borrow money from us using the Policy as the only
security for the loan. The maximum amount you may borrow is the Policy's Cash
Surrender Value on the date we receive your loan request, minus three times the
Monthly Deduction for the most recent Monthly Policy Date. You may repay all or
a portion of a loan and accrued interest at any time, if the Insured is alive.
To take a loan, you should send us a written request at our Home Office. If you
have elected the telephone transaction privilege, you may also request a loan
over the telephone. We limit the amount of a Policy loan you can take by
telephone to $25,000. (See "Telephone Transaction Privilege," Page .) We will
normally pay loan proceeds within seven days of a valid loan request.
    

      Interest Rate Charged. We charge interest on Policy loans at the fixed
rate of 6% per year. We charge interest from the date of the loan and add it to
the loan balance at the end of the Policy Year. When this interest is added to
the loan balance, it bears interest at the same rate..

      Allocation of Loans and Collateral. When you take a Policy loan, we hold
Accumulated Value in the General Account as Collateral for the Policy loan. You
may specify how you would like the Accumulated Value to be taken from the
Subaccounts of the Separate Account to serve as Collateral. If you do not so
specify, we will allocate the Policy loan to the Subaccounts in proportion to
the 


                                       34
<PAGE>   149

   
Accumulated Value in the Subaccounts. If the Accumulated Value in one or more of
the Subaccounts is insufficient to carry out your instructions, we will not
process the loan until we receive further instructions from you. Non-loaned
Accumulated Value in the General Account will become Collateral for a loan only
to the extent that the Accumulated Value in the Separate Account is
insufficient. 
    

      The Collateral for a Policy loan will initially be the loan amount. Loan
interest will be added to the Policy loan. We will take additional Collateral
for the loan interest pro rata from the Subaccounts of the Separate Account, and
then, if the amounts in the Separate Account are insufficient, from the
non-loaned portion of the General Account. At any time, the amount of the
outstanding loan under a Policy equals the sum of all loans (including due and
unpaid interest added to the loan balance) minus any loan repayments.

      Interest Credited to Amounts Held as Collateral. As long as the Policy is
in force, we will credit the amount held in the General Account as Collateral
with interest at effective annual rates we declare, but not less than 4% or such
higher minimum rate required under state law. The rate will apply to the
calendar year which follows the date of determination.

      In Policy Years 11 and thereafter, we will credit interest on amounts held
in the General Account as Collateral at a rate 0.50% per annum higher than for
similar amounts for Policies still in their first ten Policy Years.

      Preferred Policy Loans. We also currently intend to make preferred Policy
loans available on the later of the Insured's Attained Age 65 and the beginning
of Policy Year 21. The maximum amounts of these preferred loans will be 5% of
Accumulated Value per year, with a cumulative maximum of 50% of Accumulated
Value. For these preferred Policy loans, the amounts held as Collateral in the
General Account will be credited with interest at an annual rate of 6%. If both
preferred and non-preferred loans exist at the same time, we will first apply
any loan repayment to the non-preferred loan. We are not obligated to make
preferred loans available, and will make such loans available in our sole
discretion. Preferred loans may not be treated as indebtedness for federal
income tax purposes.

   
      Effect of Policy Loan. Policy loans, whether or not repaid, will have a
permanent effect on the Accumulated Value and the Cash Surrender Value, and may
permanently affect the Death Benefit of your Policy. The effect on the
Accumulated Value and Death Benefit could be favorable or unfavorable. It will
depend on whether the investment performance of the Subaccounts, and the
interest credited to the non-loaned Accumulated Value in the General Account, is
less than or greater than the interest being credited on the amounts held as
Collateral in the General Account. Compared to a Policy under which no loan is
made, values under a Policy will be lower when the credited interest rate on
Collateral is less than the investment experience of assets held in the Separate
Account and interest credited to the non-Collateral Accumulated Value in the
General Account. The longer a loan is outstanding, the greater the effect a
Policy loan is likely to have. The Death Benefit will be reduced by the amount
of any outstanding Policy loan.
    

      Loan Repayments. We will assume that any payments you make while there is
an outstanding Policy loan are premium payments, rather than loan repayments,
unless you specify in writing that a payment is a loan repayment. In the event
of a loan repayment, the amount held as Collateral in the General Account will
be reduced by an amount equal to the repayment, and such amount will be
transferred to the Subaccounts of the Separate Account and to the non-loaned
portion of the General Account based on the Net Premium allocations in effect at
the time of the repayment.

      Lapse With Loans Outstanding. The amount of an outstanding loan under a
Policy plus any accrued interest on outstanding loans is not part of Cash
Surrender Value. Therefore, the larger the amount of an outstanding loan, the
more likely it is that the Policy could lapse. (See "How the Duration of the
Policy May Vary," Page and "Policy Lapse," Page .) In addition, if the Policy is
not a Modified


                                       35
<PAGE>   150

Endowment Policy, lapse of the Policy with outstanding loans may result in
adverse federal income tax consequences. (See "Tax Treatment of Policy
Benefits," Page .)

      Tax Considerations. Any loans taken from a "Modified Endowment Contract"
will be treated as a taxable distribution. In addition, with certain exceptions,
a 10% additional income tax penalty will be imposed on the portion of any loan
that is included in income. (See "Distributions from Policies Classified as
Modified Endowment Contracts," Page .)

SURRENDER PRIVILEGE

      You may surrender your Policy for its Cash Surrender Value at any time
before the death of the Insured. The Cash Surrender Value is the Accumulated
Value minus any Policy loan and accrued interest and less any Surrender Charge.
We will calculate the Cash Surrender Value on the Valuation Day we receive, at
our Home Office, your signed written surrender request, and the Policy. You may
not request a surrender over the telephone. Coverage under the Policy will end
on the day you mail or otherwise send your written surrender request and the
Policy to us. We will ordinarily mail surrender proceeds to you within seven
days of when we receive your request. (See "Other Policy Provisions - Payment of
Policy Benefits", Page .)

      A surrender may have Federal income tax consequences. (See "Tax Treatment
of Policy Benefits," Page ).

WITHDRAWAL OF CASH SURRENDER VALUE

      You may withdraw a portion of your Policy's Cash Surrender Value at any
time before the death of the Insured and, except for employee benefit plans,
after the first Policy Anniversary. The minimum amount which you may withdraw is
$500, except for employee benefit plans, where the minimum is $100. The maximum
Withdrawal is the Cash Surrender Value on the date of receipt of the Withdrawal
request, minus three times the Monthly Deduction for the most recent Monthly
Policy Date. A Withdrawal Charge will be deducted from the amount of the
Withdrawal. For a discussion of the Withdrawal Charge, see "Charges and
Deductions - Withdrawal Charge" on Page .

      You may specify how you would like us to take a Withdrawal from the
Subaccounts of the Separate Account. If you do not so specify, we will take the
Withdrawal from the Subaccounts in proportion to the Accumulated Value in each
Subaccount. If the Accumulated Value in one or more Subaccounts is insufficient
to carry out your instructions, we will not process the Withdrawal until we
receive further instructions from you. You may take Withdrawals from the General
Account only after the Accumulated Value in the Separate Account has been
exhausted.

      The effect of a Withdrawal on the Death Benefit and Face Amount will vary
depending upon the Death Benefit Option in effect and whether the Unadjusted
Death Benefit is based on the applicable percentage of Accumulated Value. (See
"Death Benefit Options," Page .)

      Option A. The effect of a Withdrawal on the Face Amount and Unadjusted
Death Benefit under Option A can be described as follows:

            If the Face Amount divided by the applicable percentage of
      Accumulated Value exceeds the Accumulated Value just after the Withdrawal,
      a Withdrawal will reduce the Face Amount and the Unadjusted Death Benefit
      by the lesser of such excess and the amount of the Withdrawal.

            For the purposes of this illustration (and the following
      illustrations of Withdrawals), assume that the Attained Age of the Insured
      is under 40 and there is no indebtedness. The applicable percentage is
      250% for an Insured with an Attained Age under 40.


                                       36
<PAGE>   151

            Under Option A, a Policy with a Face Amount of $300,000 and an
      Accumulated Value of $30,000 will have an Unadjusted Death Benefit of
      $300,000. Assume that you take a Withdrawal of $10,000. The Withdrawal
      Charge will be $25 and the amount we pay you will be $9,975. The
      Withdrawal will reduce the Accumulated Value to $20,000 ($30,000 -
      $10,000) after the Withdrawal. The Face Amount divided by the applicable
      percentage is $120,000 ($300,000 / 2.50), which exceeds the Accumulated
      Value after the Withdrawal by $100,000 ($120,000 - $20,000). The lesser of
      this excess and the amount of the Withdrawal is $10,000, the amount of the
      Withdrawal. Therefore, the Unadjusted Death Benefit and Face Amount will
      be reduced by $10,000 to $290,000.

            If the Face Amount divided by the applicable percentage of
      Accumulated Value does not exceed the Accumulated Value just after the
      Withdrawal, then the Face Amount is not reduced. The Unadjusted Death
      Benefit will be reduced by an amount equal to the reduction in Accumulated
      Value times the applicable percentage (or equivalently, the Unadjusted
      Death Benefit is equal to the new Accumulated Value times the applicable
      percentage).

            Under Option A, a policy with a Face Amount of $300,000 and an
      Accumulated Value of $150,000 will have an Unadjusted Death Benefit of
      $375,000 ($150,000 x 2.50). Assume that you take a Withdrawal of $10,000.
      The Withdrawal Charge will be $25 and the amount we pay to you will be
      $9,975. The Withdrawal will reduce the Accumulated Value to $140,000
      ($150,000 - $10,000). The Face Amount divided by the applicable percentage
      is $120,000, which does not exceed the Accumulated Value after the
      withdrawal. Therefore, the Face Amount stays at $300,000 and the
      Unadjusted Death Benefit is $350,000 ($140,000 x 2.50).

      Option B. The Face Amount will never be decreased by a Withdrawal. A
Withdrawal will, however, always decrease the Death Benefit.

            If the Unadjusted Death Benefit equals the Face Amount plus the
      Accumulated Value, a Withdrawal will reduce the Accumulated Value by the
      amount of the Withdrawal and thus the Unadjusted Death Benefit will also
      be reduced by the amount of the Withdrawal.

            Under Option B, a Policy with a Face Amount of $300,000 and an
      Accumulated Value of $90,000 will have an Unadjusted Death Benefit of
      $390,000 ($300,000 + $90,000). Assume you take a Withdrawal of $20,000.
      The Withdrawal Charge will be $25 and the amount we pay to you will be
      $19,975. The Withdrawal will reduce the Accumulated Value to $70,000
      ($90,000 - $20,000) and the Unadjusted Death Benefit to $370,000 ($300,000
      + $70,000). The Face Amount is unchanged.

            If the Unadjusted Death Benefit immediately prior to the Withdrawal
      is based on the applicable percentage of Accumulated Value, the Unadjusted
      Death Benefit will be reduced to equal the greater of (a) the Face Amount
      plus the Accumulated Value after deducting the amount of the Withdrawal
      and Withdrawal Charge and (b) the applicable percentage of Accumulated
      Value after deducting the amount of the Withdrawal.

            Under Option B, a Policy with a Face Amount of $300,000 and an
      Accumulated Value of $210,000 will have an Unadjusted Death Benefit of
      $525,000 ($210,000 X 2.5). Assume you take a Withdrawal of $60,000. The
      Withdrawal Charge will be $25 and the amount we pay to you will be
      $59,975. The Withdrawal will reduce the Accumulated Value to $150,000
      ($210,000 - $60,000), and the Unadjusted Death Benefit to the greater of
      (a) the Face Amount plus the Accumulated Value, or $450,000 ($300,000 +
      $150,000) and (b) the Unadjusted Death Benefit based on the applicable
      percentage of the Accumulated Value, or $375,000 ($150,000 X 2.50).
      Therefore, the Unadjusted Death Benefit will be $450,000. The Face Amount
      is unchanged.

      Any decrease in Face Amount due to a Withdrawal will first reduce the most
recent increase in Face Amount, then the most recent increases, successively,
and lastly, the Initial Face Amount.


                                       37
<PAGE>   152

      Because a Withdrawal can affect the Face Amount and the Unadjusted Death
Benefit as described above, a Withdrawal may also affect the Net Amount at Risk
which is used to calculate the Cost of Insurance Charge under the Policy. (See
"Cost of Insurance Charge," Page .) Since a Withdrawal reduces the Accumulated
Value, the Cash Surrender Value of the Policy is reduced, thereby increasing the
likelihood that the Policy will lapse. (See "Policy Lapse," Page .) A request
for Withdrawal may not be allowed if such Withdrawal would reduce the Face
Amount below the Minimum Face Amount for the Policy. Also, if a Withdrawal would
result in cumulative premiums exceeding the maximum premium limitations
applicable under the Code for life insurance, we will not allow the Withdrawal.

      You may request a Withdrawal only by sending a signed written request to
us at our Home Office. You may not request a Withdrawal over the telephone. We
will ordinarily pay a Withdrawal within seven days of receiving at our Home
Office a valid Withdrawal request.

      A Withdrawal of Cash Surrender Value may have Federal income tax
consequences. (See "Tax Treatment of Policy Benefits," Page .)

FREE-LOOK PRIVILEGE

   
      The Policy provides for a "free-look" period, during which you may cancel
the Policy and receive a refund equal to the premiums paid on the Policy.
This free-look period ends on the latest of:
    

      (a)   45 days after Part A of the application for the Policy is signed

      (b)   10 days after you receive the Policy

      (c)   10 days after we mail the Notice of Withdrawal Right to you, or

      (d)   any longer period provided by state law.

To cancel your Policy, you must return it to us or to our agent within the free
look period with a written request for cancellation.

TELEPHONE TRANSACTION PRIVILEGE

   
      If you elect the telephone transaction privilege by written authorization,
you may effect changes in premium allocation, transfers, and loans of up to
$25,000 by providing instructions to us at our Home Office over the telephone.
We may suspend telephone transaction privileges at any time, for any reason, if
we deem such suspension to be in the best interests of Policy Owners. You may, 
on the application or by a written authorization, authorize your National Life
agent to provide telephone instructions on your behalf.
    

      We will employ reasonable procedures to confirm that instructions we
receive by telephone are genuine. If we follow these procedures, we will not be
liable for any losses due to unauthorized or fraudulent instructions. We may be
liable for any such losses if we do not follow these reasonable procedures. The
procedures to be followed for telephone transfers will include one or more of
the following:

      -     requiring some form of personal identification prior to acting on
            instructions received by telephone

      -     providing written confirmation of the transaction, and

      -     making a tape recording of the instructions given by telephone.

OTHER TRANSFER RIGHTS

      Transfer Right for Policy. During the first two years following Policy
issue, you may, on one occasion, transfer the entire Accumulated Value in the
Separate Account to the General Account, without regard to any limits on
transfers or free transfers.

      Transfer Right for Change in Investment Policy. If the investment policy
of a Subaccount of the Separate Account is materially changed, you may transfer
the portion of the Accumulated Value in that 


                                       38
<PAGE>   153

Subaccount to another Subaccount or to the General Account, without regard to
any limits on transfers or free transfers.

AVAILABLE AUTOMATED FUND MANAGEMENT FEATURES

      We currently offer, at no charge to you, two automated fund management
features. Only one of these features may be active for any single Policy at any
time. We are not legally obligated to continue to offer these features. Although
we have no current intention to do so, we may cease offering one or both these
features at any time, after providing 60 days prior written notice to all Owners
who are then utilizing the features being discontinued

      Dollar Cost Averaging. This feature permits you to automatically transfer
funds from the Money Market Subaccount to any other Subaccounts on a monthly
basis. You may elect Dollar Cost Averaging at issue by marking the appropriate
box on the initial application, and completing the appropriate instructions. You
may also begin a Dollar Cost Averaging program after issue by filling out
similar information on a change request form and sending it to us at our Home
Office.

      If you elect this feature, we will take the amount to be transferred from
the Money Market Subaccount and transfer it to the Subaccount or Subaccounts
designated to receive the funds, each month on the Monthly Policy Date. If you
elect Dollar Cost Averaging on your application for the Policy, it will start
with the Monthly Policy Date after the date that the reallocation of the
Accumulated Value out of the Money Market Subaccount and into the other
Subaccounts occurs. If you begin a Dollar Cost Averaging program after the free
look period is over, it will start on the next Monthly Policy Date. Dollar Cost
Averaging will continue until the amount in the Money Market Subaccount is
depleted. The minimum monthly transfer by Dollar Cost Averaging is $100, except
for the transfer which reduces the amount in the Money Market Subaccount to
zero. You may discontinue Dollar Cost Averaging at any time by sending an
appropriate change request form to the Home Office. You may not use the dollar
cost averaging feature to transfer Accumulated Value to the General Account.

   
      Dollar Cost Averaging allows you to move funds into the various investment
types on a more gradual and systematic basis than the frequency on which you pay
premiums. The periodic investment of the same amount will result in higher
numbers of units being purchased when unit prices are lower, and lower numbers
of units being purchased when unit prices are higher. This technique will not,
however, assure a profit or protect against a loss in declining markets.
Moreover, for the dollar cost averaging technique to be effective, amounts
should be available for allocation from the Money Market Subaccount through
periods of low price levels as well as higher price levels.
    

      Portfolio Rebalancing. This feature permits you to automatically rebalance
the value in the Subaccounts on a semi-annual basis, based on your premium
allocation percentages in effect at the time of the rebalancing. You may elect
it at issue by marking the appropriate box on the application, or, after issue,
by completing a change request form and sending it to our Home Office.

      In Policies utilizing Portfolio Rebalancing from the Date of Issue, an
automatic transfer will take place which causes the percentages of the current
values in each Subaccount to match the current premium allocation percentages,
starting with the Monthly Policy Date six months after the Date of Issue, and
then on each Monthly Policy Date six months thereafter. Policies electing
Portfolio Rebalancing after issue will have the first automated transfer occur
as of the Monthly Policy Date on or next following the date we receive the
election at our Home Office, and subsequent rebalancing transfers will occur
every six months from that date. You may discontinue Portfolio Rebalancing at
any time by submitting an appropriate change request form to us at our Home
Office.

      If you change your Policy's premium allocation percentages, Portfolio
Rebalancing will automatically be discontinued unless you specifically direct
otherwise.



                                       39
<PAGE>   154
       Portfolio Rebalancing will result in periodic transfers out of
Subaccounts that have had relatively favorable investment performance in
relation to the other Subaccounts to which a Policy allocates premiums, and into
Subaccounts which have had relatively unfavorable investment performance in
relation to the other Subaccounts to which the Policy allocates premiums.


POLICY RIGHTS UNDER CERTAIN PLANS

       Policies may be purchased in connection with a plan sponsored by an
employer. In such cases, all rights under the Policy rest with the Policy Owner,
which may be the employer or other obligor under the plan, and benefits
available to participants under the plan will be governed solely by the
provisions of the plan. Accordingly, some of the options and elections under the
Policy may not be available to participants under the provisions of the plan. In
such cases, participants should contact their employers for information
regarding the specifics of the plan.


                               THE GENERAL ACCOUNT


       You may allocate some or all of your Net Premiums, and transfer some or
all of the Accumulated Value of your Policy to our General Account. We credit
interest on Net Premiums and Accumulated Value allocated to the General Account
at rates we declare. These rates will not be less than 4%. The principal, after
deductions, is also guaranteed. The General Account supports National Life 's
insurance and annuity obligations. All assets in the General Account are subject
to National Life's general liabilities from business operations.

       The General Account has not, and is not required to be, registered with
the SEC under the Securities Act of 1933. The General Account has not been
registered as an investment company under the Investment Company Act of 1940.
Therefore, the General Account and the interests therein are generally not
subject to regulation under the 1933 Act or the 1940 Act. The disclosures
relating to this account which are included in this Prospectus are for your
information and have not been reviewed by the SEC. However, such disclosures may
be subject to certain generally applicable provisions of the Federal securities
laws relating to the accuracy and completeness of statements made in
prospectuses.

MINIMUM GUARANTEED AND CURRENT INTEREST RATES

   
       The Accumulated Value not held as Collateral in the General Account is
guaranteed to accumulate at a minimum effective annual interest rate of 4%. We
may credit the non-loaned Accumulated Value in the General Account with current
rates in excess of the minimum guarantee, but we are not obligated to do so. We
have no specific formula for determining current interest rates. Since we
anticipate changing the current interest rate from time to time, in our sole
discretion, allocations to the General Account made at different times are
likely to be credited with different current interest rates. We will declare an
interest rate each month to apply to amounts allocated or transferred to the
General Account in that month. The rate declared on such amounts will remain in
effect for twelve months. At the end of the 12-month period, we may declare a
new current interest rate on such amounts and accrued interest thereon (which
may be a different current interest rate than the current interest rate on new
allocations to the General Account on that date). We will determine any interest
credited on the amounts in the General Account in excess of the minimum
guaranteed rate of 4% per year in our sole discretion. You assume the risk that
interest credited may not exceed the guaranteed minimum rate. Amounts allocated
to the General Account will not share in the investment performance of our
General Account.
    

   
       Amounts deducted from the non-loaned Accumulated Value in the General
Account for Withdrawals, Policy loans, transfers to the Separate Account,
Monthly Deductions or other charges are, for the purpose of crediting interest,
accounted for on a last in, first out ("LIFO") method.
    


                                       40
<PAGE>   155
       We may change the method of crediting interest from time to time,
provided that such changes do not have the effect of reducing the guaranteed
rate of interest below 4% per annum or shortening the period for which the
interest rate applies to less than 12 months.

       We will credit interest on non-loaned Accumulated Value in the General
Account for Policies in Policy Year 11 and thereafter at rates which are 0.50%
per annum higher than those that apply to Policies still in their first ten
Policy Years.

       Calculation of Non-loaned Accumulated Value in the General Account. The
non-loaned Accumulated Value in the General Account at any time is equal to
amounts allocated and transferred to it plus interest credited to it, minus
amounts deducted, transferred or withdrawn from it.

TRANSFERS FROM GENERAL ACCOUNT

       We allow only one transfer in each Policy Year from the amount of
non-loaned Accumulated Value in the General Account to any or all of the
Subaccounts of the Separate Account. The amount you transfer from the General
Account may not exceed the greater of 25% of the value of the non-loaned
Accumulated Value in such account at the time of transfer, or $1000. We will
make the transfer as of the Valuation Day we receive your written or telephone
request at our Home Office.

                             OTHER POLICY PROVISIONS

       Maturity at 99. If the Policy is in force on the Policy Anniversary at
which the Insured is Attained Age 99, we will pay the Cash Surrender Value to
you in one sum unless you have chosen a Payment Option, and the Policy will
terminate.

       Reduced Paid - Up Benefit. Prior to maturity, you may elect to continue
the Policy in force as paid-up General Account life insurance coverage. All or a
portion of the Cash Surrender Value of the Policy will be applied to paid-up
life insurance coverage. We will pay in one lump sum any amount of the Cash
Surrender Value which you do not apply toward paid-up life insurance coverage.
You may thereafter surrender any paid-up General Account life insurance at any
time for its value.

       Payment of Policy Benefits. You may decide the form in which we pay Death
Benefit proceeds. During the Insured's lifetime, you may arrange for the Death
Benefit to be paid in a lump sum or under a Settlement Option. These choices are
also available upon surrender of the Policy for its Cash Surrender Value. If you
do not make an election, payment will be made in a lump sum. The Beneficiary may
also arrange for payment of the Death Benefit in a lump sum or under a
Settlement Option. If paid in a lump sum, we will ordinarily pay the Death
Benefit to the Beneficiary within seven days after we receive proof of the
Insured's death at our Home Office, and all other requirements are satisfied. If
paid under a Settlement Option, we will apply the Death Benefit to the
Settlement Option within seven days after we receive proof of the Insured's
death at our Home Office, and all other requirements are satisfied.

       We will pay interest on the Death Benefit from the date of death until
payment is made. The interest rate will be the highest of (a) 4% per annum, (b)
any higher rate we declare, or (c) any higher rate required by law.

       We will normally pay proceeds of a surrender, Withdrawal, or Policy loan
within seven days of when we receive your written request at our Home Office in
a form satisfactory to us.

       We will generally determine the amount of a payment on the Valuation Day
we receive all required documents. However, we may defer the determination or
payment of such amounts if the date for determining such amounts falls within
any period during which:

       (1) the New York Stock Exchange is closed (except for normal holiday
       closing); or


                                       41
<PAGE>   156


       (2) an emergency exists, as determined by the Securities and Exchange
       Commission, as a result of which it is not reasonably practicable to
       dispose of securities or to determine the value of the net assets of the
       Separate Account.

       Transactions will not be processed on the following days: New Year's Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving, the day after Thanksgiving and Christmas Day. In addition, Premium
Payments will not be allocated and transactions will not be effected to the
Money Market Subaccount on Columbus Day and Veterans Day.

       We may postpone any payment under the Policy derived from an amount paid
by check or draft until we are satisfied that the check or draft has been paid
by the bank upon which it was drawn.

       The Policy provides that we may delay payment of any amounts which are
payable as result of a surrender, Withdrawal, or Policy loan and which are
allocated to the General Account for up to six months after receipt of your
request. If we do not mail or deliver the amounts owed to you within ten days of
when we receive your request for payment, we will pay interest on the amount at
the rate then in effect under Payment Option 1 - Payment of Interest Only, from
the date of our receipt of your request for payment to the date we actually make
the payment.

       The Contract. The Policy and the application are the entire contract.
Only statements made in the application can be used to void the Policy or deny a
claim. The statements are considered representations and not warranties. Only
one of National Life's duly authorized officers or registrars can agree to
change or waive any provisions of the Policy, and only in writing. As a result
of differences in applicable state laws, certain provisions of the Policy may
vary from state to state.

       Ownership. The Owner is the Insured unless a different Owner is named in
the application or thereafter changed. While the Insured is living, the Owner is
entitled to exercise any of the rights stated in the Policy or otherwise granted
by us. If the Insured and Owner are not the same, and the Owner dies before the
Insured, these rights will vest in the estate of the Owner, unless otherwise
provided.

       Beneficiary. You designate the Beneficiary in the application for the
Policy. You may change the Beneficiary during the Insured's lifetime by sending
us a written notice. The interest of any Beneficiary who dies before the Insured
shall vest in you unless you otherwise provide.

       Change of Owner and Beneficiary. As long as the Policy is in force, you
may change the Owner or Beneficiary by sending us an acceptable written request.
The change will take effect as of the date the request is signed, whether or not
the Insured is living when we receive the request. We will not be responsible
for any payment made or action taken before we receive the written request.

       Split Dollar Arrangements. You may enter into a Split Dollar Arrangement
among the Owners or other persons under which the payment of premiums and the
right to receive the benefits under the Policy (i.e., Cash Surrender Value or
Death Benefit) are split between the parties. There are different ways of
allocating such rights.

       For example, an employer and employee might agree that under a Policy on
the life of the employee, the employer will pay the premiums and will have the
right to receive the Cash Surrender Value. The employee may designate the
Beneficiary to receive any Death Benefit in excess of the Cash Surrender Value.
If the employee dies while such an arrangement is in effect, the employer would
receive from the Death Benefit the amount which the employer would have been
entitled to receive upon surrender of the Policy and the employee's Beneficiary
would receive the balance of the proceeds.

       No transfer of Policy rights pursuant to a Split Dollar Arrangement will
be binding on us unless it is in writing and received by us. We do not assess
any specific charge for Split Dollar Arrangements.


                                       42
<PAGE>   157

       The parties who elect to enter into a Split Dollar Arrangement should
consult their own tax advisers regarding the tax consequences of such an
arrangement.

       Assignments. You may assign any and all your rights under the Policy. We
are not bound by an assignment unless it is in writing and we receive it at our
Home Office. We assume no responsibility for determining whether an assignment
is valid, or the extent of the assignee's interest. All assignments will be
subject to any Policy loan. The interest of any Beneficiary or other person will
be subordinate to any assignment. A payee who is not also the Owner may not
assign or encumber Policy benefits, and to the extent permitted by applicable
law, such benefits are not subject to any legal process for the payment of any
claim against the payee.

       Misstatement of Age and Sex. If the age or sex of the Insured at the Date
of Issue has been misstated in the application, we will adjust the Accumulated
Value of the Policy to be the amount that it would have been had the Cost of
Insurance Charges deducted been based on the correct age and sex, or as
otherwise required by state law. The adjustment will take place on the Monthly
Policy Date on or after the date on which we have proof to our satisfaction of
the misstatement. If the Insured has died, we will adjust the Accumulated Value
as of the last Monthly Policy Date prior to the Insured's death; however, if the
Accumulated Value is insufficient for that adjustment, the amount of the
Unadjusted Death Benefit will also be adjusted.

       Suicide. If the Insured dies by suicide within two years from the Date of
Issue of the Policy, our liability is limited to the payment to the Beneficiary
of a sum equal to the premiums paid less any Policy loan and accrued interest
and any Withdrawals, or other reduced amount provided by state law.

       If the Insured commits suicide within two years from the effective date
of any Policy change which increases the Unadjusted Death Benefit and for which
an application is required, the amount which we will pay with respect to the
increase will be the Cost of Insurance Charges previously made for such
increase.

       Incontestability. The Policy will be incontestable after it has been in
force during the Insured's lifetime for two years from the Date of Issue.
Similar incontestability will apply to an increase in Face Amount or
reinstatement after it has been in force during the Insured's lifetime for two
years from its effective date.

       Before such times, however, we may contest the validity of the Policy (or
changes) based on material misstatements in the initial or any subsequent
application.

   
       Dividends. The Policy is participating; however, no dividends are
expected to be paid on the Policy. If dividends are ever declared, they will be
used to purchase dividend additions or, at your direction, they may be paid in
cash or left with us to accumulate at interest. At the time of the insured 
person's death, the Death Benefit will be increased by dividends payable, if
any.
    

       Correspondence. All correspondence to you is deemed to have been sent to
you if mailed to you at your last address known to us.

       Settlement Options. In lieu of a single sum payment on death or
surrender, you may elect to apply the Death Benefit under any one of the
fixed-benefit Settlement Options provided in the Policy. The options are
described below.

   
       Payment of Interest Only. We will pay interest at a rate of 3.5% per year
on the amount of the proceeds retained by us. Upon the earlier of the payee's
death or the end of a chosen period, the proceeds retained will be paid to the 
Payee of his or her estate.
    

       Payments for a Stated Time. We will make equal monthly payments, based on
an interest rate of 3.5% per annum, for the number of years you select.

       Payments for Life. We will make equal monthly payments, based on an
interest rate of 3.5% per annum, for a guaranteed period and thereafter during
the life of a chosen person. You may elect 


                                       43
<PAGE>   158

guaranteed payment periods for 0, 10, 15, or 20 years, or for a refund period,
at the end of which the total payments will equal the proceeds placed under the
option.

       Payments of a Stated Amount. We will make equal monthly payments until
the proceeds, with interest at 3.5% per year on the unpaid balance, have been
paid in full. The total payments in any year must be at least $10 per month for
each thousand dollars of proceeds placed under this option.

       Life Annuity. We will make equal monthly payments in the same manner as
in the above Payments for Life option except that the amount of each payment
will be the monthly income provided by our then current settlement rates on the
date the proceeds become payable. No additional interest will be paid.

       Joint and Two Thirds Annuity. We will make equal monthly payments, based
on an interest rate of 3.5% per year, while two chosen persons are both living.
Upon the death of either, two-thirds of the amount of those payments will
continue to be made during the life of the survivor. We may require proof of the
ages of the chosen persons.

       50% Survivor Annuity. We will make equal monthly payments, based on an
interest rate of 3.5% per year, during the lifetime of the chosen primary
person. Upon the death of the chosen primary person, 50% of the amount of those
payments will continue to be made during the lifetime of the secondary chosen
person. We may require proof of the ages of the chosen persons.

   
       We may pay interest in excess of the stated amounts under the first four
options listed above, but not the last three. Under the first two, and fourth
options above, the Payee has the right to change options or to withdraw all or
part of the remaining proceeds. For additional information concerning the
payment options, see the Policy.
    


                                OPTIONAL BENEFITS


       You may include the following benefits, which are subject to the
restrictions and limitations set forth in the applicable Policy Riders, in your
Policy at your option. Election of any of these optional benefits involves an
additional cost.

       Waiver of Monthly Deductions. If you elect the Waiver of Monthly
Deductions Rider, we will waive Monthly Deductions against the Policy if the
Insured becomes totally disabled, before age 65 and for at least 120 days. If
total disability occurs after age 60 and before age 65, then we will waive
Monthly Deductions only until the Insured reaches Attained Age 65, or for a
period of two years, if longer. The monthly cost of this Rider is based on
sex-distinct rates (except for Policies issued in conjunction with employee
benefit plans, where the cost of this Rider will not vary by sex) multiplied by
the Monthly Deduction on the Policy. We will add this cost to the Monthly
Deduction on the Policy.

       Accidental Death Benefit. The Accidental Death Rider provides for an
increased Death Benefit in the event that the Insured dies in an accident. If
you elect this Rider, we will add the monthly cost of this Rider to the Monthly
Deduction on the Policy.

       Guaranteed Insurability Option. This Rider permits you to increase the
Face Amount of the Policy, within certain limits, without being required to
submit satisfactory proof of insurability at the time of the request for the
increase. Again, if you elect this Rider, we will add the monthly cost of this
Rider to the Monthly Deduction on the Policy.

   
       Guaranteed Death Benefit. If you choose this Rider, we will guarantee
that the Policy will not lapse prior to the Insured's Attained Age 70, or 20
years from the Date of Issue of the Policy, if longer, regardless of the
Policy's investment performance. To keep this Rider in force, you must pay
cumulative premiums greater than the Minimum Guarantee Premium from the Date of
Issue. The Minimum Guarantee Premium for Policies with the Guaranteed Death
Benefit Rider will be higher than for those without the Guaranteed Death Benefit
Rider, all other things being equal. We will test the Policy monthly for this
qualification, and if not met, we will send you a notice, and you will have 61
days from the date we mailed the notice to pay a premium sufficient to keep the
Rider in force. The premium
    


                                       44
<PAGE>   159

   
required will be the Minimum Guarantee Premium from the Date of Issue, plus two
times the Minimum Monthly Premium, minus premiums previously paid. The Rider
will be cancelled if a sufficient premium is not paid during that 61-day period.
If cancelled, the Rider cannot be reinstated.
    

       The cost of the Guaranteed Death Benefit Rider is $0.01 per thousand of
Face Amount per month. This Rider is available only at issue, and only for Issue
Ages 0-65.

       If while the Guaranteed Death Benefit Rider is in force, the Accumulated
Value of the Policy is not sufficient to cover the Monthly Deductions, Monthly
Deductions will be made until the Accumulated Value of the Policy is exhausted,
and will thereafter be deferred, and collected at such time as the Policy has
positive Accumulated Value.

       If you increase the Face Amount of a Policy subject to the Guaranteed
Death Benefit Rider, the Rider's guarantee will extend to the increased Face
Amount. This will result in increased Minimum Guarantee Premiums.

       If you have elected both the Waiver of Monthly Deductions Rider and the
Guaranteed Death Benefit Rider, and Monthly Deductions are waived because of
total disability, then we will also waive the Minimum Guarantee Premiums
required to keep the Guaranteed Death Benefit Rider in force during the period
that Monthly Deductions are being waived.

   
       If you wish to keep this Rider in force, you must limit Withdrawals and
Policy loans to the excess of premiums paid over the sum of the Minimum Monthly
Premiums in effect since the Date of Issue. If you take a Policy loan or
Withdrawal for an amount greater than such excess, the Guaranteed Death Benefit
Rider will enter a 61-day lapse-pending notification period, and will be
cancelled if you do not pay a sufficient premium.
    

   
       Accelerated Benefits Rider. This Rider pays a reduced benefit prior to 
the death of the Insured, in certain circumstances where a terminal or chronic
illness creates a need for access to the death benefit. This Rider is not
available in all states, and its terms may vary by state. There is no cost for
this Rider. It can be included in a Policy at issue, or can be added after
issue, for Insureds ages 0-85. The maximum amount payable under the Rider is
$500,000. An Insured who has a chronic illness, as defined in the Rider, at the
time the Rider is issued, may not receive benefits under the Rider for five
years after its issue.
    

                        FEDERAL INCOME TAX CONSIDERATIONS


INTRODUCTION

       The following summary provides a general description of the Federal
income tax considerations associated with the Policy and does not purport to be
complete or to cover all tax situations. This discussion is not intended as tax
advice. Counsel or other competent tax advisors should be consulted for more
complete information. This discussion is based upon understanding of the present
Federal income tax laws. No representation is made as to the likelihood of
continuation of the present Federal income tax laws or as to how they may be
interpreted by the Internal Revenue Service.


                                       45
<PAGE>   160

TAX STATUS OF THE POLICY

       In order to qualify as a life insurance contract for Federal income tax
purposes and to receive the tax treatment normally accorded life insurance
contracts under Federal tax law, a life insurance policy must satisfy certain
requirements which are set forth in the Internal Revenue Code. Guidance as to
how these requirements are to be applied is limited. Nevertheless, National Life
believes that a Policy issued on the basis of a standard rate class should
satisfy the applicable requirements. There is less guidance, however, with
respect to a policy issued on a substandard basis (i.e., a rate class involving
higher than standard mortality risk) and it is not clear whether such a policy
will in all cases satisfy the applicable requirements, particularly if the Owner
pays the full amount of premiums permitted under the Policy. Nevertheless,
National Life believes it reasonable to conclude that such a Policy should be
treated as a life insurance contract for Federal income tax purposes. If it is
subsequently determined that a Policy does not satisfy the applicable
requirements, National Life may take appropriate steps to bring the policy into
compliance with such requirements and National Life reserves the right to modify
the policy as necessary in order to do so.

       In certain circumstances, owners of variable life insurance policies have
been considered for Federal income tax purposes to be the owners of the assets
of separate accounts supporting their contracts due to their ability to exercise
investment control over those assets. Where this is the case, the policyowners
have been currently taxed on income and gains attributable to separate account
assets. There is little guidance in this area, and some features of the policy,
such as the flexibility of Policy Owners to allocate premium payments and
Accumulated Values, have not been explicitly addressed in published rulings.
While National Life believes that the policy does not give Policy Owners
investment control over Separate Account assets, we reserve the right to modify
the policy as necessary to prevent the Policy Owner from being treated as the
owner of the Separate Account assets supporting the Policy.

         In addition, the Code requires that the investments of the Separate
Account be "adequately diversified" in order for the policy to be treated as a
life insurance contract for Federal income tax purposes. It is intended that the
Separate Account, through the Funds, will satisfy these diversification
requirements.

         The following discussion assumes that the Policy will qualify as a life
insurance contract for Federal income tax purposes.

TAX TREATMENT OF POLICY BENEFITS

         In General. National Life believes that the death benefit under a
Policy should be excludible from the gross income of the beneficiary. Federal,
state and local estate, inheritance, transfer, and other tax consequences of
ownership or receipt of Policy proceeds depend on the circumstances of each
Policy Owner or beneficiary. A tax advisor should be consulted on these
consequences.

         Generally, a Policy Owner will not be deemed to be in constructive
receipt of the Accumulated Value until there is a distribution. When
distributions from a Policy occur, or when loans are taken out from or secured
by a Policy, the tax consequences depend on whether the Policy is classified as
a "Modified Endowment Contract."

         Modified Endowment Contracts. Under the Internal Revenue Code, certain
life insurance contracts are classified as "Modified Endowment Contracts," with
less favorable tax treatment than other life insurance contracts. Due to the
flexibility of the Policy as to premium payments and benefits, the individual
circumstances of each Policy will determine whether it is classified as a
Modified Endowment 


                                       46

Contract. The rules are too complex to be summarized here, but generally depend
on the amount of premium payments made during the first seven policy years.
Certain changes in a policy after it is issued could also cause it to be
classified as a Modified Endowment Contract. A current or prospective Policy
Owner should consult with a competent advisor to determine whether a policy
transaction will cause the Policy to be classified as a Modified Endowment
Contract.

       Distributions Other Than Death Benefits from Modified Endowment
Contracts. Policies classified as Modified Endowment Contracts are subject to
the following tax rules:

       (1)    All distributions other than death benefits from a Modified
              Endowment Contract, including distributions upon surrender and
              withdrawals, will be treated first as distributions of gain
              taxable as ordinary income and as tax-free recovery of the Policy
              Owner's investment in the Policy only after all gain has been
              distributed.

       (2)    Loans taken from or secured by a Policy classified as a Modified
              Endowment Contract are treated as distributions and taxed
              accordingly.

       (3)    A 10 percent additional income tax is imposed on the amount
              subject to tax except where the distribution or loan is made when
              the Policy Owner has attained age 59-1/2 or is disabled, or where
              the distribution is part of a series of substantially equal
              periodic payments for the life (or life expectancy) of the Policy
              Owner or the joint lives (or joint life expectancies) of the
              Policy Owner and the Policy Owner's beneficiary or designated
              beneficiary.

       Distributions Other Than Death Benefits from Policies that are not
Modified Endowment Contracts. Distributions other than death benefits from a
Policy that is not classified as a Modified Endowment Contract are generally
treated first as a recovery of the Policy Owner's investment in the policy and
only after the recovery of all investment in the policy as taxable income.
However, certain distributions which must be made in order to enable the Policy
to continue to qualify as a life insurance contract for Federal income tax
purposes if policy benefits are reduced during the first 15 policy years may be
treated in whole or in part as ordinary income subject to tax.

       Loans from or secured by a Policy that is not classified as a Modified
Endowment Contract are generally not treated as distributions. However, the tax
consequences associated with preferred Policy loans is less clear and a tax
adviser should be consulted about such loans.

       Finally, neither distributions from nor loans from or secured by a Policy
that is not a Modified Endowment Contract are subject to the 10 percent
additional income tax.

       Investment in the Policy. Your investment in the Policy is generally your
aggregate premium payments. When a distribution is taken from the Policy, your
investment in the Policy is reduced by the amount of the distribution that is
tax-free.

       Policy Loan Interest. In general, interest paid on any loan under a
Policy will not be deductible.

       Multiple Policies. All Modified Endowment Contracts that are issued by
National Life (or its affiliates) to the same Policy Owner during any calendar
year are treated as one Modified Endowment Contract for purposes of determining
the amount includible in the Policy Owner's income when a taxable distribution
occurs.

       Business Uses of the Policy. Businesses can use the Policy in various
arrangements, including nonqualified deferred compensation or salary continuance
plans, split dollar insurance plans, executive bonus plans, tax exempt and
nonexempt welfare benefit plans, retiree medical benefit plans and others. The
tax consequences of such plans may vary depending on the particular facts and
circumstances. If you are purchasing the Policy for any arrangement the value of
which depends in part on its tax consequences, you should consult a qualified
tax adviser. In recent years, moreover, Congress has adopted new rules relating
to life insurance owned by businesses. Any business contemplating the purchase
of a new Policy or a change in an existing Policy should consult a tax adviser.

       Continuation Beyond Age 100. The tax consequences of continuing the
Policy beyond the Insured's 100th year are unclear. You should consult a tax
adviser if you intend to keep the Policy in force beyond the Insured's 100th
year.

SPECIAL RULES FOR EMPLOYEE BENEFIT PLANS

       If a trustee under a pension or profit-sharing plan, or similar deferred
compensation arrangement, owns a Policy, the Federal and state income and estate
tax consequences could differ. A tax adviser should be consulted with respect to
such consequences. Policies owned under these types of plans may also be subject
to restrictions under the Employee Retirement Income Security Act of 1974
("ERISA"). You should consult a qualified adviser regarding ERISA.

       The amounts of life insurance that may be purchased on behalf of a
participant in a pension or profit-sharing plan are limited.

       The current cost of insurance for the net amount at risk is treated as a
"current fringe benefit" and must be included annually in the plan participant's
gross income. We report this cost (generally referred to as the "P.S. 58" cost)
to the participant annually.

       If the plan participant dies while covered by the plan and the Policy
proceeds are paid to the participant's beneficiary, then the excess of the death
benefit over the Accumulated Value is not taxable. However, the Accumulated
Value will generally be taxable to the extent it exceeds the participant's cost
basis in the Policy.

POSSIBLE TAX LAW CHANGES

       Although the likelihood of legislative changes is uncertain, there is
always the possibility that the tax treatment of the policy could change by
legislation or otherwise. Consult a tax adviser with respect to legislative
developments and their effect on the Policy.

POSSIBLE CHARGES FOR NATIONAL LIFE'S TAXES

   
       At the present time, National Life makes no charge for any Federal, state
or local taxes (other than the charge for state premium taxes and the DAC tax)
that may be attributable to the Subaccounts or to the policies. National Life
reserves the right to charge the Subaccounts for any future taxes or economic
burden National Life may incur.

           POLICIES ISSUED IN CONJUNCTION WITH EMPLOYEE BENEFIT PLANS


       Policies may be acquired in conjunction with employee benefit plans,
including the funding of qualified pension plans meeting the requirements of
Section 401 of the Code.

       For employee benefit plan Policies, the maximum cost of insurance rates
used to determine the monthly Cost of Insurance Charge are based on the
Commissioners' 1980 Standard Ordinary Mortality Tables NB and SB. Under these
Tables, mortality rates are the same for male and female Insureds of a
particular Attained Age and Rate Class. (See "Cost of Insurance Charge," Page .)

       Illustrations reflecting the premiums and charges for employee benefit
plan Policies will be provided upon request to purchasers of such Policies.

       There is no provision for misstatement of sex in the employee benefit
plan Policies. (See "Misstatement of Age and Sex," Page .) Also, the rates used
to determine the amount payable under a particular Settlement Option will be the
same for male and female Insureds. (See "Settlement Options," Page .)


              LEGAL DEVELOPMENTS REGARDING UNISEX ACTUARIAL TABLES


       In 1983, the United States Supreme Court held in Arizona Governing
Committee v. Norris that optional annuity benefits provided under an employee's
deferred compensation plan could not, under Title VII of the Civil Rights Act of
1964, vary between men and women on the basis of sex. In that case, the Court
applied its decision only to benefits derived from contributions made on or
after August 1, 1983. Subsequent decisions of lower federal courts indicate that
in other factual circumstances the Title VII prohibition of sex-distinct
benefits may apply at an earlier date. In addition, legislative, regulatory, or
decisional authority of some states may prohibit use of sex-distinct mortality
tables under certain circumstances. The Policies offered by this Prospectus,
other than employee benefit plan Policies (see "Policies Issued in Conjunction
with Employee Benefit Plans," Page ) are based upon actuarial tables which
distinguish between men and women and, thus, the Policy provides different
benefits to men and women of the same age. Accordingly, employers and employee
organizations should consider, in consultation with legal counsel, the impact of
these authorities on any employment-related insurance or benefits program before
purchasing the Policy and in determining whether an employee benefit plan Policy
is appropriate.

                                  VOTING RIGHTS


       We will invest all of the assets held in the Subaccounts of the Separate
Account in shares of corresponding Portfolios of the Funds. The Funds do not
hold routine annual shareholders' meetings. Shareholders' meetings will be
called whenever each Fund believes that it is necessary to vote to elect the
Board of Directors of the Fund and to vote upon certain other matters that are
required to be approved or ratified by the shareholders of a mutual fund.

       We are the legal owner of Fund shares and as such have the right to vote
upon any matter that may be voted upon at a shareholders' meeting. However, in
accordance with the SEC's view of present applicable law, we will vote the
shares of the Funds at meetings of the shareholders of the appropriate Fund or
Portfolio in accordance with instructions of Policy Owners. We will vote Fund
shares held in each Subaccount of the Separate Account for which Owners do not
send timely instructions in the same proportion as those shares in that
Subaccount for which instructions are received.

       If you have a voting interest, we will send you proxy material and a form
for giving voting instructions. You may vote, by proxy or in person, only as to
the Portfolios that correspond to the 


                                       49
<PAGE>   164

Subaccounts in which your Policy values are allocated. We will determine the
number of shares held in each Subaccount attributable to a Policy for which you
may provide voting instructions by dividing the Policy's Accumulated Value in
that account by the net asset value of one share of the corresponding Portfolio
as of the record date for the shareholder meeting. We will count fractional
shares. For each share of a Portfolio for which Owners have no interest, we will
cast votes, for or against any matter, in the same proportion as Owners provide
voting instructions.

       If required by state insurance officials, we may disregard voting
instructions if they would require shares to be voted so as to cause a change in
the investment objectives or policies of one or more of the Portfolios, or to
approve or disapprove an investment policy or investment adviser of one or more
of the Portfolios. In addition, we may disregard voting instructions in favor of
certain changes initiated by an Owner or the Fund's Board of Directors if our
disapproval of the change is reasonable and is based on a good faith
determination that the change would be contrary to state law or otherwise
inappropriate, considering the portfolio's objectives and purposes, and the
effect the change would have on us. If we disregard voting instructions, we will
advise you of that action and our reasons in the next semi-annual report to
Owners.

       Shares of the Funds are currently being offered to variable life
insurance and variable annuity separate accounts of life insurance companies
other than National Life that are not affiliated with National Life. National
Life understands that shares of these Funds also will be voted by such other
life insurance companies in accordance with instructions from their
policyholders invested in such separate accounts. This will dilute the effect of
your voting instructions.

                CHANGES IN APPLICABLE LAW, FUNDING AND OTHERWISE

       The voting rights described in this Prospectus are created under
applicable Federal securities laws. If changes in these laws or regulations
eliminate the necessity to solicit your voting instructions or restrict such
voting rights, we may proceed in accordance with these laws or regulations.

       We may also take the steps listed below, if we feel such an action is
reasonably necessary. In doing so we would comply with all applicable laws,
including approval of Owners, if so required:

       (1) to make changes in the form of the Separate Account, if in our
       judgment such changes would serve the interests of Owners or would be
       appropriate in carrying out the purposes of the Policies, for example:

              (i)    operating the Separate Account as a management company
                     under the 1940 Act

              (ii)   deregistering the Separate Account under the 1940 Act if
                     registration is no longer required

              (iii)  combining or substituting separate accounts

              (iv)   transferring the assets of the Separate Account to another
                     separate account or to the General Account

              (v)    making changes necessary to comply with, obtain or continue
                     any exemptions from the 1940 Act; or

              (vi)   making other technical changes in the Policy to conform
                     with any action described herein;

       (2) if in our judgment a Portfolio no longer suits the investment goals
       of the Policy, or if tax or marketing conditions so warrant, to
       substitute shares of another investment portfolio for shares of such
       Portfolio;

       (3) to eliminate, combine, or substitute Subaccounts and establish new
       Subaccounts, if in its judgment marketing needs, tax considerations, or
       investment conditions so warrant;

       (4) to transfer assets from a Subaccount to another Subaccount or
       separate account if the transfer in our judgment would best serve
       interests of Policy Owners or would be appropriate in carrying out the
       purposes of the Policies; and

       (5) to modify the provisions of the Policies to comply with applicable
       laws.


                                       50

       We have reserved all rights in respect of our corporate name and any part
thereof, including without limitation the right to withdraw its use and to grant
its use to one or more other separate accounts and other entities.

       If your Policy has Accumulated Value in a Subaccount that is eliminated,
we will give you at least 30 days notice before the elimination, and will
request that you name the Subaccount or Subaccounts (or the General Account) to
which the Accumulated Value in that Subaccount should be transferred. If you do
not name a new Subaccount, then we will use the Money Market Subaccount. In any
case, if in the future we impose a transfer charge or establish limits on the
number of transfers or free transfers, no charge will be made for this transfer,
and it will not count toward any limit on transfers or free transfers.

                            DISTRIBUTION OF POLICIES

       We sell Policies through agents who are licensed by state insurance
authorities to sell our variable life insurance policies, and who are also
registered representatives of Equity Services, Inc. ("ESI") or registered
representatives of broker/dealers who have Selling Agreements with ESI. ESI,
whose address is National Life Drive, Montpelier, Vermont 05604, is a registered
broker/dealer under the Securities Exchange Act of 1934 (the "1934 Act") and a
member of the National Association of Securities Dealers, Inc. (the "NASD"). ESI
is an indirect wholly-owned subsidiary of National Life, formed on October 7,
1968. ESI acts as the principal underwriter, as defined in the 1940 Act, of the
Policies, and for the Separate Account pursuant to an Underwriting Agreement to
which the Separate Account, ESI and National Life are parties.

       National Life has sought approval to sell the Policies in all states and
the District of Columbia. However, all approvals may not be obtained. The
Policies are offered and sold only in those states where their sale is lawful.

       The directors of ESI are Patrick E. Welch, Thomas H. MacLeay, Rodney A.
Buck, all of whose principal occupations are disclosed under "Directors and
Officers of National 

                                       52

Life" above, and Joseph M. Rob, the Chairman, Chief Executive Officer and
President of ESI. ESI's other officers are:


         John M. Grab, Jr.       Senior Vice President & Chief Financial Officer
         Stephen A. Englese      Vice President - Financial Products
         Gregory D. Teese        Vice President - Compliance
         Budd A. Shedaker        Assistant Vice President - Communications
         D. Russell Morgan       Counsel
         Sharon E. Bernard       Treasurer & Controller
         Lisa A. Pettrey         Secretary
         JoAnn K. Morissette     Assistant Secretary

       The principal business address of all these individuals is National Life
Drive, Montpelier, Vermont 05604.

       We do the insurance underwriting, determine a proposed Insured's Rate
Class, and determine whether to accept or reject an application for a Policy. We
will refund any premiums paid if a Policy ultimately is not issued or will
refund the applicable amount if the Policy is returned under the free look
provision.

   
       Agents who are ESI registered representatives are compensated for sales 
of the Policies on a commission basis and with other forms of compensation.
During the first Policy Year, agent commissions will not be more than 50% of the
premiums paid up to a target amount (which is a function of Face Amount, and
which is used primarily to determine commission payments) and 3% of the premiums
paid in excess of that amount. For Policy Years 2 through 10, the agent
commissions will not be more than 4% of the premiums paid up to the target
amount, and 3% of premiums paid in excess of that amount. For Policy year 11 and
thereafter, agent commissions will be 1.5% of all premiums paid. For premiums
received in the year following an increase in Face Amount and attributable to
the increase, agent commissions will not be more than 48.5% up to the target
amount for the increase. Full time agents of National Life who achieve specified
annual sales goals may be eligible for compensation in addition to the amounts
stated above.
    

   
       Dealers other than ESI will receive gross dealer concessions during the
first Policy Year of 85% of the premiums paid up to the target amount and 4% of
the premiums paid in excess of that amount. For Policy Years 2 through 10, the
gross dealer concession will not be more than 4% of the premiums paid. For
Policy Year 11 and thereafter, the gross dealer concession will be 1.5% of all
premiums paid. For premiums received in the year following an increase in Face
Amount and attributable to the increase, the gross dealer concession will not be
more than 50% up to the target amount for the increase.

                             PREPARING FOR YEAR 2000


       Many computer systems were designed using only two digits to designate
years. These systems may not be able to distinguish the year 2000 from the year
1900. Like all financial services providers, we utilize computer systems that
may be effected by Year 2000 transition issues. We also rely on service
providers, including the Funds, that also may be affected. We have developed,
and are in the process of implementing, a Year 2000 transition plan, and are
confirming that our service providers are also so engaged. The resources that
are being devoted to this effort are substantial. It is difficult to predict
with precision whether the amount of resources ultimately devoted, or the
outcome of these efforts, will have any negative impact on us. However, as of
the date of this prospectus, it is not anticipated that you will experience
negative effects on your investment, or on the services provided in connection
with your Policy, as a result of Year 2000 transition implementation. We
currently anticipate that our computer systems will be Year 2000 compliant on or
about June 30, 1999, but there can be no assurance that we will be successful,
or that interaction with other service providers will not impair our services at
that time.

                                  LEGAL MATTERS


       Sutherland, Asbill & Brennan LLP of Washington, D.C. has provided advice
on legal matters relating to certain aspects of Federal securities law
applicable to the issue and sale of the Policies. Matters of Vermont law
pertaining to the Policies, including National Life's right to issue the
Policies and its qualification to do so under applicable laws and regulations
issued thereunder, have been passed upon by Michele S. Gatto, Senior Vice
President and General Counsel of National Life.

       The Separate Account is not a party to any litigation. There are no
material legal proceedings involving National Life which are likely to have a
material adverse effect upon the Separate Account or upon the ability of
National Life to meet its obligations under the Policies. ESI is not engaged in
any litigation of any material nature.

       In recent years life insurance companies have been named as defendants in
class action lawsuits relating to life insurance pricing and sales practices.
During 1998, National Life settled a group of class action lawsuits of this
nature. While the ultimate cost of the settlement is not yet known, National
Life set aside a reserve during 1998 of approximately $40.6 million to account
for the cost of the settlement of these cases.

       National Life is also party to ordinary routine litigation incidental to
the business, none of which is expected to have a material adverse effect upon
its ability to meet its obligations under the Policies.


                              FINANCIAL STATEMENTS


       The financial statements of National Life and of the relevant Subaccounts
of the Separate Account appear on the following pages. The financial statements
of National Life should be distinguished from the financial statements of the
Separate Account and should be considered only as bearing upon National Life's
ability to meet its obligations under the Policies.

                             insurance coverage continues. To prevent lapse, the
                             Owner must during the Grace Period make a premium
                             payment equal to the sum of any amount by which the
                             past Monthly Deductions have been in excess of Cash
                             Surrender Value, plus three times the Monthly
                             Deduction due the date the Grace Period began.

                                   a day that is not a Valuation Date, it will
                                   be deemed to have occurred on the next
                                   Valuation Date.

VALUATION PERIOD                   The time between two successive Valuation
                                   Days. Each Valuation Period includes a
                                   Valuation Day and any non-Valuation Day or
                                   consecutive non-Valuation Days immediately

                                   APPENDIX A

  ILLUSTRATION OF DEATH BENEFITS, ACCUMULATED VALUES AND CASH SURRENDER VALUES

       The following tables illustrate how the Death Benefits, Accumulated
Values and Cash Surrender Values of a Policy may change with the investment
experience of the Separate Account. The tables show how the Death Benefits,
Accumulated Values and Cash Surrender Values of a Policy issued to an Insured of
a given age, sex and Rate Class would vary over time if the investment return on
the assets held in each Portfolio of each of the Funds were a uniform, gross,
annual rate of 0%, 6% and 12%.

   
       The tables on Pages A-2 to A-7 illustrate a Policy issued to a male
Insured, Age 40 in the Preferred Nonsmoker Rate Class with a Face Amount of
$250,000 and Planned Periodic Premiums of $3,000 for Death Benefit Option A, and
$4,000 for Death Benefit Option B, in each case paid at the beginning of each
Policy Year. The Death Benefits, Accumulated Values and Cash Surrender Values
would be lower if the Insured was in a standard nonsmoker, smoker or substandard
class since the cost of insurance charges are higher for these classes. Also,
the values would be different from those shown if the gross annual investment
returns averaged 0%, 6% and 12% over a period of years, but fluctuated above and
below those averages for individual Policy Years. The net annual rate of return
shown in the tables is the gross annual rate reduced to reflect the average
investment advisory fee and average operating expenses of the Funds after
reimbursement and the Mortality and Expense Risk Charge.


    

       The second column of the tables show the amount to which the premiums
would accumulate if an amount equal to those premiums were invested to earn
interest, after taxes, at 5% compounded annually. The columns shown under the
heading "Guaranteed" assume that throughout the life of the Policy, the monthly
charge for cost of insurance is based on the maximum level permitted under the
Policy (based on the 1980 CSO Smoker/Nonsmoker Table), the guaranteed maximum
Monthly Administrative Charge of $7.50 per Policy plus $0.07 per thousand of
Face Amount applies, and Monthly Deductions are reduced by 0.50% per annum for
Policy Years after 10; the columns under the heading "Current" assume that
throughout the life of the Policy, the monthly charge for cost of insurance is
based on the current cost of insurance rate, and the Monthly Administrative
Charge is set at its current level of $7.50 per Policy.

   
       The amounts shown in all tables reflect an averaging of certain other
asset charges described below that may be assessed under the Policy, depending
upon how premiums are allocated. The total of the asset charges reflected in the
Current and Guaranteed illustrations, including the Mortality and Expense Risk
Charge of 0.90%, is 1.72%. This total charge is based on an assumption that an
Owner allocates the Policy values equally among the Subaccounts of the Separate
Account.
    

   
       These asset charges reflect an investment advisory fee of 0.65%, which
represents a simple average of the fees incurred by the Portfolios during 1998
and expenses of 0.17% which is based on a simple average of the actual expenses
incurred by the Portfolios during 1998, adjusted, as appropriate, to take into
account expense reimbursement arrangements expected to be in place for 1999. In
the absence of the reimbursement arrangements for some of the Portfolios, the
other asset charges would have totaled an average of 0.64%. If the reimbursement
arrangements were discontinued, the Accumulated Values and Cash Surrender Values
of a Policy which allocates Policy values equally among the Subaccounts would be
lower than those shown in the following tables. For information on Fund
expenses, see the prospectuses for the Funds accompanying this prospectus.
    

       The tables also reflect the fact that no charges for Federal or state
income taxes are currently made against the Separate Accounts. If such a charge
is made in the future, it would take a higher gross annual rate of return to
produce the same Policy values.

       The tables illustrate the Policy values that would result based upon the
hypothetical investment rates of return if premiums are paid and allocated as
indicated, no amounts are allocated to the General Account, and no Policy loans
are made. The tables are also based on the assumption that the Owner has not
requested an increase or decrease in the Face Amount, that no Withdrawals have
been made and no transfers have been made in any Policy Year.

       Upon request, National Life will provide a comparable illustration based
upon the proposed Insured's Age and Rate Class, the Death Benefit Option, Face
Amount, Planned Periodic Premiums and Riders requested.

The Death Benefit may, and the Accumulated Values and Cash Surrender Values
will, differ if premiums are paid in different amounts or frequencies.

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. THE DEATH
BENEFIT, ACCUMULATED VALUE AND CASH SURRENDER VALUE FOR A POLICY WOULD BE
DIFFERENT FROM THOSE SHOWN IF ACTUAL RATES OF INVESTMENT RETURN APPLICABLE TO
THE POLICY AVERAGED 0%, 6% OR 12% OVER A PERIOD OF YEARS, BUT ALSO FLUCTUATED
ABOVE OR BELOW THAT AVERAGE FOR INDIVIDUAL POLICY YEARS. THE DEATH BENEFIT,
ACCUMULATED VALUE AND CASH SURRENDER VALUE WOULD ALSO BE DIFFERENT FROM THOSE
SHOWN, DEPENDING ON THE INVESTMENT ALLOCATIONS MADE TO THE SUBACCOUNTS OF THE
SEPARATE ACCOUNT AND THE DIFFERENT RATES OF RETURN OF THE SUBACCOUNTS IF THE
ACTUAL RATES OF INVESTMENT RETURN APPLICABLE TO THE POLICY AVERAGED 0%, 6%, OR
12%, BUT VARIED ABOVE OR BELOW THAT AVERAGE FOR PARTICULAR SUBACCOUNTS. NO
REPRESENTATIONS CAN BE MADE THAT THESE HYPOTHETICAL RATES OF RETURN CAN BE
ACHIEVED FOR ANY ONE YEAR OR SUSTAINED OVER ANY PERIOD OF TIME.

                        Report of Independent Accountants



To the Board of Directors and Policyholders
of National Life Insurance Company


In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations and comprehensive income, changes in
equity, and cash flows present fairly, in all material respects, the financial
position of National Life Insurance Company and its subsidiaries (the Company)
at December 31, 1998 and 1997, and the results of their operations and their
cash flows for the years then ended in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
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 provide a
reasonable basis for the opinion expressed above.

As discussed in Note 10 to the financial statements, the Company changed its
method of accounting in 1998 for the cost of computer software developed or
obtained for internal use.

As discussed in Note 11 to the financial statements, on January 1, 1999,
National Life Insurance Company converted from a mutual to a stock insurance
company as part of a reorganization into a mutual holding company corporate
structure.

NATIONAL LIFE INSURANCE COMPANY and SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - NATURE OF OPERATIONS

National Life Insurance Company (National Life) was chartered in 1848. National
Life is also known by its registered trade name "National Life of Vermont".
National Life employs about 750 people in its home office in Montpelier,
Vermont. With its affiliates and subsidiaries, National Life offers a broad
range of financial products and services, including life insurance, annuities,
disability income insurance, mutual funds, investment advisory and

National Life primarily develops and distributes individual life insurance and
annuity products. National Life markets its products primarily to small business
owners, professionals and high net worth individuals by providing financial
solutions in the form of estate, business succession and retirement planning,
deferred compensation and other key executive fringe benefit plans. Insurance
and annuity products are primarily distributed through about 40 general agencies
in major metropolitan areas throughout the United States. National Life also
distributes its products through brokers and banks. National Life has about
224,000 policyholders and is licensed to do business in all 50 states and the

from residents of New York and California.

Through affiliates National Life also distributes and provides investment
advisory and administrative services to the Sentinel Group Funds, Inc. The
Sentinel Funds' $3.1 billion of net assets represent thirteen mutual funds
managed on behalf of about 116,000 individual, corporate and institutional
shareholders worldwide.


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The accompanying consolidated financial statements of National Life and
subsidiaries have been prepared in conformity with generally accepted accounting
principles (GAAP).

The consolidated financial statements include the accounts of National Life
Insurance Company and its subsidiaries. All significant intercompany
transactions and balances have been eliminated in consolidation. Certain
reclassifications have been made to conform prior periods presented to the
current year's presentation.

The preparation of financial statements in conformity with GAAP 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.

INVESTMENTS

Cash and cash equivalents include highly liquid debt instruments purchased with
remaining maturities of three months or less.

Available-for-sale debt securities and equity securities are reported at
estimated fair value. Debt and equity securities that experience declines in
value that are other than temporary are written down with a corresponding charge
to realized losses.


                                      F-7

Mortgage loans are reported at amortized cost, less valuation allowances for the
excess, if any, of the amortized cost of impaired loans over the estimated fair
value of the related collateral. Changes in valuation allowances are included in
net realized gains and losses.

Policy loans are reported at their unpaid balance and are fully collateralized
by related cash surrender values.

Real estate investments are reported at depreciated cost. Real estate acquired
in satisfaction of debt is transferred to real estate at estimated fair value.

Net realized investment gains and losses are recognized using the specific
identification method and include changes in valuation allowances. Changes in
the estimated fair values of available-for-sale debt and equity securities are
reflected in comprehensive income after adjustments for related deferred policy
acquisition costs, present value of future profits of insurance acquired, income
taxes and minority interests.

DEFERRED POLICY ACQUISITION COSTS

Commissions and other costs of acquiring business that vary with and are
primarily related to the production of new business are generally deferred.

Deferred policy acquisition costs for participating life insurance, universal
life insurance and investment-type annuities are amortized in relation to
estimated gross margins or profits. Amortization is adjusted retrospectively for
actual experience and when estimates of future gross margins or profits are
revised. Balances of deferred policy acquisition costs for these products are
adjusted for related unrealized gains and losses on available-for-sale debt and
equity securities through comprehensive income, net of related income taxes.

Deferred policy acquisition costs for non-participating term life insurance and
disability income insurance is amortized in relation to premium income using
assumptions consistent with those used in computing policy benefit liabilities.

Balances of deferred policy acquisition costs are regularly evaluated for
recoverability from product margins or profits.

PRESENT VALUE OF FUTURE PROFITS OF INSURANCE ACQUIRED

Present value of future profits of insurance acquired is the
actuarially-determined present value of future projected profits from policies
in force at the date of their acquisition, and is amortized in relation to gross
profits of those policies. Amortization is adjusted retrospectively for actual
experience and when estimates of future profits are revised.

PROPERTY AND EQUIPMENT

Property and equipment is reported at depreciated cost. Real property is
depreciated over 40 years using the straight-line method. Furniture and
equipment is depreciated using accelerated depreciation methods over 7 years and
5 years, respectively.

SEPARATE ACCOUNTS

Separate accounts are segregated funds relating to certain variable annuity and
variable life policies, and National Life's pension plans. Separate account
assets are primarily common stocks, bonds, mortgage loans, and real estate and
are carried at estimated fair value. Separate account liabilities reflect
separate account policyholders' interests in separate account assets, include
the actual investment performance of the respective accounts and are not
guaranteed. Separate account results relating to these policyholders' interests
are excluded from revenues and expenses.

POLICY LIABILITIES

Policy benefit liabilities for participating life insurance are developed using
the net level premium method, with interest and mortality assumptions used in
calculating policy cash surrender values. Participating life insurance terminal
dividends are accrued in relation to gross margins.

Policy benefit liabilities for non-participating life insurance, disability
income insurance and certain annuities are developed using the net level premium
method, with assumptions for interest, mortality, morbidity, withdrawals and
expenses based principally on company experience.

Policyholders' account balances for universal life insurance and investment-type
annuities represent amounts that inure to the benefit of the policyholders
(before surrender charges).

POLICYHOLDERS' DIVIDENDS

Policyholders' dividends are the pro-rata amount of dividends earned that will
be paid or credited at the next policy anniversary. Dividends are based on a
scale that seeks to reflect the relative contribution of each group of policies
to National Life's overall operating results. The dividend scale is approved
annually by National Life's Board of Directors.

RECOGNITION OF INSURANCE INCOME AND RELATED EXPENSES

Premiums from traditional life and certain annuities are recognized as revenue
when due from the policyholder. Benefits and expenses are matched with income by
providing for policy benefit liabilities and the deferral and amortization of
policy acquisition costs so as to recognize profits over the life of the
policies.

Premiums from universal life and investment-type annuities are reported as
increases in policyholders' accounts. Revenues for these policies consist of
mortality charges, policy administration fees and surrender charges deducted
from policyholders' accounts. Policy benefits charged to expense include benefit
claims in excess of related policyholders' account balances.

Premiums from disability income policies are recognized as revenue over the
period to which the premiums relate.

FEDERAL INCOME TAXES

National Life files a consolidated federal income tax return that includes all
of its wholly-owned subsidiaries. Current federal income taxes are charged or
credited to operations based upon amounts estimated to be payable or recoverable
as a result of taxable operations for the current year. Deferred income tax
assets and liabilities are recognized based on temporary differences between
financial statement carrying amounts and income tax bases of assets and
liabilities using enacted income tax rates and laws.

National Life periodically lends certain U.S. government or corporate bonds to
approved counterparties to enhance the yield of its bond portfolio. National
Life receives cash collateral for at least 103% of the market value of
securities loaned. Collateral adequacy is evaluated daily and periodically
adjusted for changes in the market value of securities loaned. The carrying
values of securities loaned are unaffected by the transaction. Collateral held
(included in cash and cash equivalents) and the corresponding liability for
collateral held (included in other liabilities and accrued expenses) were $193.5
million and $19.8 million at December 31, 1998 and 1997, respectively.

National Life also periodically enters into repurchase agreements on U.S.
Treasury securities to enhance the yield of its bond portfolio. These
transactions are accounted for as financings because the securities received at
the end of the repurchase period are identical to the securities transferred.
There were no open transactions at December 31, 1998. The repurchase liability
is included in other liabilities and was $234.6 million at December 31, 1997.

Impaired loans are mortgage loans where it is not probable that all amounts due
under the contractual terms of the loan will be received. Impaired loans
without valuation allowances are mortgage loans where the estimated fair value
of the collateral exceeds the recorded investment in the loan. For these
impaired loans, interest income is recognized on an accrual basis, subject to
recoverability from the estimated fair value of the loan collateral. For
impaired loans with valuation allowances, interest income is recognized on a
cash basis.

DERIVATIVES

National Life purchases over-the-counter options and exchange-traded futures on
the Standard & Poor's 500 (S&P 500) index to hedge obligations relating to
equity indexed products. When the S&P 500 index increases, increases in the
intrinsic value of the options and fair value of futures are offset by increases
in equity indexed product account values. When the S&P 500 index decreases,
National Life's loss is the decrease in the fair value of futures and is limited
to the premium paid for the options.

National Life purchases options only from highly rated counterparties. However,
in the event a counterparty failed to perform, National Life's loss would be
equal to the fair value of the net options held from that counterparty.

The option premium is expensed over the term of the option. Amortization of the
option premium is reflected in investment income. Interest credited includes
amounts that would be credited on the next policy anniversary based on the S&P
500 index's value at the reporting date, offset by changes in the intrinsic
value of options held and changes in the fair value of futures. The call options
are included in other invested assets and are carried at amortized cost plus
intrinsic value, if any, of the call options as of the valuation date.

The notional amounts and net book value of options and futures at December 31

For cash and cash equivalents carrying value approximates estimated fair value.

Debt and equity securities estimated fair values are based on quoted values
where available. Where quoted values are not available, estimated fair values
are based on discounted cash flows using current interest rates of similar
securities.

Mortgage loan fair values are estimated as the average of discounted cash flows
under different scenarios of future mortgage interest rates (including
appropriate provisions for default losses and borrower prepayments).

For variable rate policy loans the unpaid balance approximates fair value. Fixed
rate policy loan fair values are estimated based on discounted cash flows using
the current variable policy loan rate (including appropriate provisions for
mortality and repayments).

Derivatives estimated fair values are based on quoted values.

Investment products include flexible premium annuities, single premium deferred
annuities and supplementary contracts not involving life contingencies.
Investment product fair values are estimated as the average of discounted cash
flows under different scenarios of future interest rates of A-rated corporate
bonds and related changes in premium persistency and surrenders.

Debt fair values are estimated based on discounted cash flows using current
interest rates of similar securities.


NOTE 4 - INSURANCE IN-FORCE AND REINSURANCE

National Life reinsures certain risks assumed in the normal course of business.
For individual life products, National Life generally retains no more than $3.0
million of risk on any person (excluding accidental death benefits and dividend
additions). Reinsurance for life products is ceded under yearly renewable term,
coinsurance, and modified coinsurance. Disability income products are
significantly reinsured under coinsurance and modified coinsurance.

National Life remains liable in the event any reinsurer is unable to meet its
assumed obligations. National Life regularly evaluates the financial condition
of its reinsurers and concentrations of credit risk of reinsurers to minimize
its exposure to significant losses from reinsurer insolvencies.

The effects of reinsurance for the years ended December 31 were as follows (in
thousands):

Management believes it is more likely than not that National Life will realize
the benefit of deferred tax assets.

National Life's federal income tax returns are routinely audited by the IRS.
The IRS has examined tax returns through 1993 and is currently examining the
years 1994 and 1995. In management's opinion adequate tax liabilities have been
established for all open years.

NOTE 6 - BENEFIT PLANS

National Life sponsors a qualified defined benefit pension plan covering
substantially all employees. The plan is administered by National Life's
Benefits Committee and is non-contributory, with benefits based on an
employee's retirement age, years of service and compensation near retirement.
Plan assets are primarily bonds and common stocks held in a National Life
separate account and funds invested in an annuity contract issued by National
Life. National Life also sponsors other, non-qualified pension plans, including
a non-contributory defined benefit plan for general agents that provides
benefits based on years of service and sales levels, a contributory defined
benefit plan for certain employees, agents and general agents and a
non-contributory defined supplemental benefit plan for certain executives.
These non-qualified defined benefit pension plans are not funded.

National Life sponsors four defined benefit postretirement plans that provide
medical, dental and life insurance benefits to employees and agents.
Substantially all employees and agents may be eligible for retiree benefits if
they reach normal retirement age and meet certain minimum service requirements
while working for National Life. Most of the plans are contributory, with
retiree contributions adjusted annually, and contain cost sharing features such
as deductibles and copayments. The plans are not funded and National Life pays
for plan benefits on a current basis. The cost of these benefits is recognized
as earned.

During 1997, National Life offered enhanced pension and postretirement benefits
to employees meeting certain defined eligibility requirements. The program
resulted in special termination benefits for the expected present value of the
enhancements to benefits, curtailment gains for reductions in the pension
benefit obligations relating to assumed increases in future compensation levels
and settlement gains for the pro-rata recognition of actuarial gains on lump
sum settlements of pension benefit obligations.

The status of the defined benefit plans at December 31 was as follows (in
thousands):

The total projected benefit obligation for non-qualified defined benefit pension
plans was $81.4 million and $69.1 million at December 31, 1998 and 1997,
respectively. The total accumulated benefit obligation for these plans was $75.2
million and $66.3 million at December 31, 1998 and 1997, respectively.

The actuarial assumptions used in determining benefit obligations at December
31, were as follows:

Health care cost trend rates grade to 5% in year 2000 and remain level
thereafter. Increasing the assumed health care trend rates by one percentage
point in each year would increase the APBO by about $3.2 million and the 1998
service and interest cost components of net periodic postretirement benefit cost
by about $0.1 million. Decreasing the assumed health care trend rates by one
percentage point in each year would reduce the APBO by about $2.6 million and
the 1998 service and interest cost components of net periodic postretirement
benefit cost by about $0.1 million. National Life uses the straight-line method
of amortization for prior service cost and unrecognized gains and losses.

National Life provides employee savings and 401(k) plans where up to 3% of an
employee's compensation may be invested by the employee in either plan with
matching funds contributed by the company. National Life also contributes
various amounts of an employee's compensation (up to certain levels) to a 401(k)
account. Additional voluntary employee contributions may be made to the plans
subject to certain limits. Company contributions to these plans generally vest
within two years.

NOTE 8 - SALES PRACTICE REMEDIATION COSTS

During 1997, several class action lawsuits were filed against National Life in
various states related to the sale of life insurance policies during the 1980's
and 1990's. National Life specifically denied any wrongdoing. National Life
agreed to a settlement of these class action lawsuits in June 1998. This
agreement was subsequently approved by the court in October 1998. The settlement
provides class members with various policy enhancement options and new product
purchase discounts. Class members may instead pursue alternative dispute
resolution according to predetermined guidelines. Management believes that while
the ultimate cost of this litigation is still uncertain, it is unlikely (after
considering existing provisions) to have a material adverse effect on National
Life's financial position.

The New York Insurance Department recognizes only statutory accounting practices
for determining and reporting the financial condition and results of operations
of an insurance company and for determining solvency under the New York
Insurance Law. No consideration is given by the New York Insurance Department to
financial statements prepared in accordance with generally accepted accounting
principles in making such determinations.

NOTE 10 - NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities (FAS 133), which establishes accounting and reporting
standards for derivative instruments. FAS 133 requires that an entity recognize
all derivatives as either assets or liabilities at fair value in the statement
of financial position, and establishes special accounting for the following
three types of hedges: fair value hedges, cash flow hedges, and hedges of
foreign currency exposures of net investments in foreign operations. The
statement is effective for fiscal years beginning after June 15, 1999. National
Life is currently assessing the impact of the adoption of FAS 133.

In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use (SOP 98-1). SOP 98-1 requires that
certain costs incurred in developing internal use computer software be
capitalized and provides guidance for determining whether computer software is
considered to be for internal use. This statement is effective for fiscal years
beginning after December 15, 1998. National Life adopted SOP 98-1 effective
January 1, 1998. The adoption of SOP 98-1 resulted in net after tax
capitalization (after current year amortization) of approximately $2 million in
software costs.

NOTE 11 - SUBSEQUENT EVENTS

On January 1, 1999, National Life converted from a mutual to a stock insurance
company as part of a reorganization into a mutual holding company corporate
structure.

Prior to the conversion, policyowners held policy contractual and membership
rights from National Life. The contractual rights, as defined in the various
insurance and annuity policies, remained with National Life after the
conversion. Membership interests held by policyowners of National Life at
December 31, 1998 were converted to membership interests in National Life
Holding Company, an upstream corporation. National Life Holding Company
currently owns all the outstanding shares of NLV Financial, which in turn
currently owns all the outstanding shares of National Life.

This reorganization was approved by policyowners of National Life and was
completed with the approval of the Vermont Department of Banking, Insurance,
Securities, and Health Care Administration.

                        REPORT OF INDEPENDENT ACCOUNTANTS






To the Board of Directors of National Life Insurance Company
and Policyholders of National Variable Life Insurance Account - Varitrak Segment


In our opinion, the accompanying statement of net assets and the related
statements of operations and of changes in net assets present fairly, in all
material respects, the financial position of each of the sub-accounts
constituting the National Variable Life Insurance Account - Varitrak Segment (a
segment within a Separate Account of National Life Insurance Company) (the
Segment) at December 31, 1998, and the results of each of their operations and
each of their changes in net assets for the years ended December 31, 1998 and
1997 and the period from March 11, 1996 through December 31, 1996, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Segment'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 audits 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 confirmation of securities at December 31, 1998 by
correspondence with the funds, provide a reasonable basis for the opinion
expressed above.

NATIONAL VARIABLE LIFE INSURANCE ACCOUNT - VARITRAK SEGMENT
(A Segment within a Separate Account of National Life Insurance Company)
NOTES TO THE FINANCIAL STATEMENTS


NOTE 1 - NATURE OF OPERATIONS

National Variable Life Insurance Account (the Variable Account) began operations
on March 11, 1996 and is registered as a unit investment trust under the
Investment Company Act of 1940, as amended. The operations of the Variable
Account are part of National Life Insurance Company (National Life). The
Variable Account was established by National Life as a separate investment
account to invest the net premiums received from the sale of certain variable
life insurance products. Equity Services, Inc., an indirect wholly-owned
subsidiary of National Life, is the principal underwriter for the variable life
insurance policies issued by National Life. Sentinel Advisors Company, an
indirectly-owned subsidiary of National Life, provides investment advisory
services for certain Market Street Fund, Inc. mutual fund portfolios.

National Life maintains two segments within the Variable Account. The Varitrak
Segment (the Segment) within the Variable Account was established on March 11,
1996 and is used exclusively for National Life's flexible premium variable life
insurance products known collectively as Varitrak. On May 1, 1998, National Life
established the Estate Builder Segment within the Variable Account to be used
exclusively for National Life's flexible premium variable life insurance
products known collectively as Estate Builder.

The Segment invests the accumulated policyholder account values in shares of
mutual fund portfolios within Market Street Fund, Inc., Alger American Fund,
Variable Insurance Products Fund (VIPF), American Century, JP Morgan, Strong
Capital, Neuberger & Berman and Goldman Sachs. Net premiums received by the
Segment are deposited in investment portfolios as designated by the
policyholder, except for initial net premiums on new policies which are first
invested in the Market Street Fund Money Market Portfolio. Policyholders may
also direct the allocations of their account value between the various
investment portfolios within the Segment and a declared interest account (within
the General Account of National Life) through participant transfers.

There are twenty-six sub-accounts within the Segment. Each sub-account, which
invests exclusively in the shares of the corresponding portfolio, comprises the
accumulated policyholder account values of the underlying variable life
insurance policies investing in the sub-account.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

These financial statements have been prepared in conformity with generally
accepted accounting principles (GAAP). The preparation of financial statements
in accordance with GAAP requires management to make estimates and assumptions
that affect the reported amounts and disclosures in the financial statements.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed in the preparation of the
Segment's financial statements.

INVESTMENTS

The mutual fund portfolios consist of the Market Street Fund Money Market,
Market Street Fund Growth (formerly Market Street Fund Common Stock), Market
Street Fund Aggressive Growth, Market Street Fund Managed, Market Street Fund
Bond, Market Street Fund International, Market Street Fund Sentinel Growth,
Alger American Growth, Alger American Small Capitalization, VIPF Equity-Income,
VIPF Overseas, VIPF Growth, VIPF High Income, VIPF Contra, VIPF Index 500,
American Century Value, American Century Income & Growth, JP Morgan
International Opportunities, JP Morgan Small Company, Strong Capital Management
Opportunity II, Strong Capital Management Growth II, Neuberger & Berman
Partners, Goldman Sachs International Equity, Goldman Sachs Global Income,
Goldman Sachs CORE Small Cap Equity, and Goldman Sachs Mid Cap Equity Fund (the
Portfolios). The American Century, JP Morgan, Strong Capital, Neuberger &
Berman, and Goldman Sachs mutual fund portfolios were added to 



                                      F-39

the Segment in 1998. The assets of each portfolio are held separate from the
assets of the other portfolios and each has different investment objectives and
policies. Each portfolio operates separately and the gains or losses in one
portfolio have no effect on the investment performance of the other portfolios.

INVESTMENT VALUATION

The investments in the Portfolios are valued at the closing net asset value per
share as determined by the portfolio at the end of each period. The change in
the difference between cost and market value is reflected as unrealized gain
(loss) in the Statement of Operations.

INVESTMENT TRANSACTIONS

Investment transactions are accounted for on the trade date (date the order to
buy or sell is executed) and dividend income (including capital gain
distributions) are recorded on the ex-dividend date. The cost of investments
sold was determined using the average cost method prior to 1998. Effective
January 1, 1998, the Variable Account changed its method of calculating the cost
of investments sold from the average cost method to the first in, first out
method (FIFO). Management believes FIFO better matches policyholder and
sub-account investment activity. This change had no impact on the results of
operations for 1998 or prior years, and no impact on the unit value reported
within each of the sub-accounts. Management also believes it would be
impractical to calculate the cumulative effect of this change on previously
reported realized and unrealized gains and losses; however, during 1998 the
change increased net realized gains by $ 176,300 and decreased net unrealized
gains by the same amount.

FEDERAL INCOME TAXES

The operations of the Segment are part of, and taxed with, the total operations
of National Life. Under existing federal income tax law, investment income and
capital gains attributable to the Segment are not taxed.

NOTE 3 - CHARGES AND EXPENSES

National Life deducts a daily charge from the Segment based on an annual rate of
 .9% of each sub-account's net asset value for its assumption of mortality and
expense risks. The mortality risk assumed is that the insureds under the
policies may die sooner than anticipated. The expense risk assumed is that
expenses incurred in issuing and administering the policies may exceed expected
levels.

Cost of insurance charges are deducted monthly from each policyholder's
accumulated account value for the insurance protection provided and are remitted
to National Life. These charges vary based on the net amount at risk, attained
age of the insured, and other factors. As partial compensation for
administrative services provided, National Life also deducts a monthly
administrative charge from each policyholder's accumulated account value.

Certain deferred administrative and sales charges are deducted from the
policyholder's accumulated account value if the underlying variable life
insurance policy is surrendered or lapsed prior to the end of the fifteenth
policy year.

NOTE 6 - LOANS

Policyholders may obtain loans after the first policy year as outlined in the
variable life insurance policy. At the time a loan is granted, accumulated value
equal to the amount of the loan is designated as collateral and transferred from
the Segment to the General Account of National Life. Interest is credited by
National Life at predetermined rates on collateral held in the General Account.
This interest is periodically transferred to the Segment.

NOTE 7 - DISTRIBUTION OF NET INCOME

The Segment does not expect to declare dividends to policyholders from
accumulated net income. The accumulated net income will be distributed to
policyholders as withdrawals (in the form of death benefits, surrenders or
policy loans) in excess of the policyholders' net contributions to the Segment.

                          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.

                             RULE 484 UNDERTAKING

         Article V, Section 7.1 of the Bylaws of National Life Insurance Company
("National Life" or the "Company") provides that, in accordance with the
provisions of the Section, the Company shall indemnify directors, officers and
employees of the Company or any other corporation served at the request of the
Company, and their heirs, executors and administrators, shall be indemnified to
the maximum extent permitted by law against all costs and expenses, including
judgments paid, settlement costs, and counsel fees, reasonably incurred in the
defense of any claim in which such person is involved by virtue of his or her
being or having been such a director, officer, or employee.

         The Bylaws are filed as Exhibit 1.A.6(b) to the Registration Statement.

         Vermont law authorizes Vermont corporations to provide indemnification
to directors, officers and other persons.

         National Life owns a directors and officers liability insurance policy
covering liabilities that directors and officers of National Life and its
subsidiaries and affiliates may incur in acting as directors and officers.

         Insofar as indemnification for liability arising under the Securities
Act of 1933 (the "Act") 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 other 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 RELATING TO FEES AND CHARGES


         National Life Insurance Company ("the Company") hereby represents that
the fees and charges deducted under the variable life insurance policies
described in the prospectuses contained in this registration statement are, in
the aggregate, reasonable in relationship to the services rendered, the
expenses expected to be incurred, and the risks assumed by the Company.

                                  April, 1999

                            DESCRIPTION OF ISSUANCE,
                 TRANSFER AND REDEMPTION PROCEDURES FOR POLICIES
                      PURSUANT TO RULE 6e-3(T)(b)(12)(iii)
                  FOR FLEXIBLE PREMIUM LIFE INSURANCE POLICIES
                                    ISSUED BY
                         NATIONAL LIFE INSURANCE COMPANY


This document sets forth the administrative procedures that will be followed by
National Life Insurance Company ("National Life") in connection with the
issuance of its flexible premium variable adjustable benefit life insurance
policy ("Policy" or "Policies"), the transfer of assets held thereunder, and the
redemption by Policy owners ("Owners") of their interests in those Policies.
Capitalized terms used herein have the same meaning as in the prospectus for the
Policy that is included in the current registration statement on Form S-6 for
the Policy as filed with the Securities and Exchange Commission ("Commission" or
"SEC").

I.     PROCEDURES RELATING TO PURCHASE AND ISSUANCE OF THE POLICIES AND
       ACCEPTANCE OF PREMIUMS

       A.     OFFER OF THE POLICIES, APPLICATIONS, INITIAL NET PREMIUMS, AND
              ISSUANCE

              1. Offer of the Policies. The Policies will be offered and sold
              subject to established cost of insurance schedules and
              underwriting standards in accordance with state insurance laws.
              Insurance charges will not be the same for all Owners selecting
              the same Face Amount. Insurance is based on the principle of
              pooling and distribution of mortality risks, which assumes that
              each Owner pays insurance charges commensurate with the Insured's
              mortality risk as actuarially determined utilizing factors such as
              age, sex and health and occupation. A uniform insurance charge for
              all Insureds would discriminate unfairly in favor of those
              Insureds representing greater risk. Although there will be no
              uniform insurance charges for all Insureds, there will be a
              uniform insurance rate for all Insureds of the same Rate Class,
              age, sex and Policy size. A description of the Monthly Deduction
              under the Policy, which includes charges for cost of insurance,
              for the Monthly Administrative Charge and for supplemental
              benefits, is at Appendix A to this memorandum.

              2. Application. Persons wishing to purchase a Policy must complete
              an application and submit it to National Life through a National
              Life authorized agent. This agent will also be a registered
              representative of a securities broker-dealer registered with the
              U.S. Securities and Exchange Commission, which broker-dealer will
              normally be Equity Services, Inc., an indirect wholly-owned
              subsidiary of National Life. The applicant must specify the
              Insured, and provide certain required information about the
              Insured. The applicant will also specify a plan for paying Planned
              Periodic Premiums, which are level premiums of a specified amount
              at specified intervals, either quarterly, semi-annually or
              annually, and may request that National Life send reminder notices
              at the appropriate intervals. Also, under the Check-O-Matic plan,
              the Owner can select a monthly payment schedule pursuant to which
              premium payments will be automatically deducted from a bank
              account or other source, rather than being "billed." An
              application will not be deemed to be complete unless all required

                                     A-1

<PAGE>   2
              information, including without limitation age, sex, and medical
              and other background information, has been provided in the
              application.

              3.     Minimum Initial Premium. An applicant for a new Policy 
              must pay at least a Minimum Initial Premium, which if not 
              submitted with the application or during the underwriting 
              period, must be submitted when the Policy is delivered. 
              (Generally, policy coverage does not become effective until the 
              application has been accepted and the Minimum Initial Premium is 
              received in good order at National Life's home office ("Home 
              Office"). If, however, a premium less than the Minimum Initial 
              Premium has been received at the Home Office, a Policy may be 
              issued, but the agent delivering the Policy to the Owner will 
              collect the balance due before leaving the Policy with the 
              Owner). National Life may specify the form in which a premium 
              payment must be made in order for the premium to be in "good 
              order." Ordinarily, a check will be deemed to be in good order 
              upon receipt, although National Life may require that the check 
              first be converted into federal funds. In addition, for a premium 
              to be received in "good order," it must be accompanied by all 
              required supporting documentation, in whatever form required.

                     The Minimum Initial Premium is equal to theMinimum Monthly
              Premium. The Minimum Monthly Premium depends on a number of
              factors, such as the Insured's sex, Issue Age, Rate Class, Death
              Benefit Option, requested Initial Face Amount and any optional
              benefits selected. The Minimum Monthly Premium is the monthly
              amount used to determine the Minimum Guarantee Premium. The
              Minimum Guarantee Premium is used for purposes of determining
              whether, during the first five Policy Years or, if the optional
              Guaranteed Death Benefit Rider has been purchased, prior to age
              70, or 20 years from the Date of Issue of the Policy, if longer,
              the Policy will not lapse regardless of investment performance.
              During the period a death benefit guarantee is in effect under a
              Policy, the Minimum Guarantee Premium is the sum of the Minimum
              Monthly Premiums in effect on each Monthly Policy Date, plus all
              Withdrawals and outstanding Policy loans and accrued interest. The
              Minimum Monthly Premium may change if, for example, a Face Amount
              Change or Death Benefit Option Change is elected by the Owner.

              4.     Minimum Face Amount. The minimum Face Amount for which
              National Life will issue a Policy is generally $50,000; however,
              exceptions may be made for employee benefit plans.

              5.     Receipt of Application and Underwriting. Upon receipt of a
              completed application in good order from an applicant, National
              Life will follow certain insurance underwriting (risk evaluation)
              procedures designed to determine whether the proposed Insured is
              insurable. This process may involve such verification procedures
              as medical examinations and may require that further information
              be provided about the proposed Insured before a determination can
              be made.

                     The underwriting process determines the Rate Class to which
              the Insured is assigned. This original Rate Class applies to the
              Initial Face Amount. The Rate Class may change upon an increase in
              Face Amount, as to the increase (see Death Benefits below).

                                      A-2
<PAGE>   3
                     A Policy cannot be issued until the initial underwriting
              procedure has been completed, and any supplemental beneficiary
              forms and forms required in accordance with state insurance laws
              have been received. The Date of Issue occurs when the above steps
              have been completed, the application has been accepted, the
              Minimum Initial Premium has been received, and the computerized
              issue system has generated a printed Policy.

                     National Life reserves the right to reject an application
              for any reason permitted by law. If an application is rejected,
              any premium received will be returned, without interest.

              6.     Acceptance of Application and Date of Issue. If an 
              application is accepted, insurance coverage under the Policy is
              effective as of the Date of Issue. The Date of Issue is set forth
              in the Policy. From the time the application for a Policy is
              signed until the time the Policy is issued, an applicant can,
              subject to National Life's underwriting rules, obtain temporary
              insurance protection, pending issuance of the Policy, by answering
              "no" to the Health Questions of the Receipt & Temporary Life
              Insurance Agreement and submitting (a) a complete application
              including any medical questionnaire required, and (b) payment of
              the Minimum Initial Premium.

                     The Date of Issue is used to determine Policy Years and
              Monthly Policy Dates, as well as to measure suicide and
              contestability periods.

       B.     ADDITIONAL PREMIUMS

              1.     Additional Premiums Permitted. Additional premiums may be
              paid in any amount, frequency and time period, subject to the
              following limits:

              -      A premium must be at least $50 and must be sent to the Home
                     Office. National Life may require satisfactory evidence of
                     insurability before accepting any premium if it increases
                     the Unadjusted Death Benefit more than it increases the
                     Accumulated Value.

              -      Total premiums paid on a cumulative basis also may not
                     exceed guideline premium limitations for life insurance set
                     forth in the Internal Revenue Code.

              -      No premium will be accepted after the Insured reaches
                     Attained Age 99 (although loan payments will be permitted
                     after Attained Age 99).

              -      National Life will monitor Policies and will attempt to
                     notify an owner on a timely basis if the Owner's Policy is
                     in jeopardy of becoming a modified endowment contract under
                     the Internal Revenue Code.

              2.     Refund of Excess Premium Amounts. If at any time a premium
              is paid that would result in total premiums exceeding limits
              established by law to qualify a Policy as a life insurance policy,
              National Life will only accept that portion of the premium that
              would make total premiums equal the maximum amount that may be
              paid under the Policy. The excess will be promptly refunded, and
              if paid by check, after such check has cleared. If there is an
              outstanding loan on the 


                                      A-3
<PAGE>   4

              Policy, the excess may instead be applied as a loan repayment.
              Excess amounts under $3 will not be refunded.

              3.     Planned Premiums. At the time of application, each Owner
              will select a Planned Periodic Premium schedule, based on annual,
              semi-annual, or quarterly payments. The Owner may request National
              Life to send a premium reminder notice from National Life at the
              specified interval. The Owner may change the Planned Periodic
              Premium frequency and amount by notification to National Life at
              its Home Office ot to a National life authorized agent. Also,
              under the Check-O-Matic plan, the Owner can select a monthly
              payment schedule pursuant to which premium payments will be
              automatically deducted from a bank account or other source, rather
              than being "billed."

              4.     Crediting Additional Premiums

                     Premiums will be credited to the Policy and the Net
              Premiums will be invested as requested on the Valuation Date that
              the premium is received in good order by the Home Office in
              accordance with the procedures described below in Section I.F.
              National Life may specify the form in which a premium payment must
              be made in order for the premium to be in "good order."
              Ordinarily, a check will be deemed to be in good order upon
              receipt, although National Life may require that the check first
              be converted into federal funds. In addition, for an additional
              premium to be received in "good order," it must be accompanied by
              all required supporting documentation in whatever form required.

       C.     OVERPAYMENTS AND UNDERPAYMENTS. In accordance with industry
              practice, National Life will establish procedures to handle errors
              in initial and additional premium payments to refund overpayments
              and collect underpayments, except for amounts under $3, or such
              other threshhold as may be established from time to time.

       D.     SPECIAL PREMIUMS -- PREMIUMS UPON INCREASE IN FACE AMOUNT, DURING
              A GRACE PERIOD, OR UPON REINSTATEMENT

              1.     Upon Increase in Face Amount. Depending on the Accumulated
              Value at the time of an increase in the Face Amount and the amount
              of the increase requested, an additional premium or change in the
              amount of Planned Periodic Premiums may be advisable. National
              Life will notify the Owner if a premium is necessary or a change
              appropriate.

              2.     During a Grace Period. If the Cash Surrender Value is
              insufficient to cover the Monthly Deductions and other charges
              under the Policy and the Grace Period (as described below) expires
              without a sufficient payment, the Policy will lapse. During the
              first five Policy Years, however, the Policy will not lapse if the
              Minimum Guarantee Premium has been paid. In addition, if the Owner
              has elected at issue the Guaranteed Death Benefit Rider, and has
              paid premiums at all times at least equal to the Minimum Guarantee
              Premium, the Policy will not lapse prior to the Insured's Attained
              Age 70, or 20 years from the Date of Issue of the Policy if
              longer, regardless of whether the Cash Surrender Value is
              sufficient to cover the Monthly Deductions.



                                      A-4
<PAGE>   5

              -      The Policy provides for a 61-day Grace Period that is
                     measured from the date on which notice is sent by National
                     Life. Thus, the Policy does not lapse, and the insurance
                     coverage continues, until the expiration of this Grace
                     Period.

              -      In order to prevent lapse, the Owner must, during the Grace
                     Period, make a premium payment equal to the sum of any
                     amount by which the past Monthly Deductions have been in
                     excess of Cash Surrender Value, plus three times the
                     Monthly Deduction due the date the Grace period began. This
                     amount will be identified in the notice sent out pursuant
                     to the immediately preceding paragraph.

              -      Failure to make a sufficient payment within the Grace
                     Period will result in lapse of the Policy without value.

              3.     Upon Reinstatement. A Policy that lapses without value may
              be reinstated at any time within five years (or longer period if
              required in a particular state) after the beginning of the Grace
              Period by submitting evidence of the Insured's insurability
              satisfactory to National Life and payment of an amount sufficient
              to provide for two times the Monthly Deduction due on the date the
              Grace Period began plus three times the Monthly Deduction due on
              the effective date of reinstatement. The effective date of the
              reinstatement will be the Monthly Policy Date on or next following
              the date the reinstatement application is approved.

              -      Upon reinstatement, the Accumulated Value will be based
                     upon the premium paid to reinstate the Policy and the
                     Policy will be reinstated with the same Date of Issue as it
                     had prior to the lapse.

              -      Neither the five year no lapse guarantee nor the Guaranteed
                     Death Benefit Rider may be reinstated.

       E.     REPAYMENT OF A POLICY LOAN

              1.     Loan Repayments Permitted. While the Insured is living, the
              Owner may repay all or a portion of a loan and accrued interest.

              2.     Repayment Crediting and Allocation. National Life will
              assume that any payments made while there is an outstanding loan
              on the Policy are premium payments, rather than loan repayments,
              unless it receives written instructions that a payment is a loan
              repayment. In the event of a loan repayment, the amount held as
              collateral in the General Account will be reduced by an amount
              equal to the repayment, and such amount will be transferred to the
              Subaccounts of the Separate Account and to the non-loaned portion
              of the General Account based on the net premium allocations in
              effect at the time of the repayment.

       F.     ALLOCATIONS OF PREMIUMS AMONG THE ACCOUNTS

              1.     The Separate Account, Subaccounts, and General Account. The
                     variable benefits under the Policies are supported by
                     National Variable Life Insurance Account (the "Separate
                     Account"). The Separate Account currently consists of
                     eleven Subaccounts, the assets of which are used to
                     purchase shares of a designated corresponding mutual fund
                     Portfolio that 


                                      A-5
<PAGE>   6

                     is part of one of the following Funds: the Market Street
                     Fund, the Variable Insurance Products Fund, and the Alger
                     American Fund. Each Fund is registered under the Investment
                     Company Act of 1940 as an open-end management investment
                     company. Owners also may allocate Net Premiums to National
                     Life's General Account. Additional Subaccounts may be added
                     from time to time to invest in portfolios of the Market
                     Street Fund, Variable Insurance Products Fund, Alger
                     American Fund, or any other investment company.

              2.     Allocations Among the Accounts. Net Premiums are allocated
                     to the Subaccounts and the General Account in accordance
                     with the following procedures.

                     a.   General. The Net Premium equals the premium paid less
                     the Premium Tax Charge. In the application for the Policy,
                     the Owner will indicate how Net Premiums should be
                     allocated among the Subaccounts of the Separate Account
                     and/or the General Account. Such allocations may be changed
                     at any time by the Owner by written notice to National Life
                     at the Home Office, or if the telephone transaction
                     privilege has been elected, by telephone instructions. The
                     percentages of each Net Premium that may be allocated to
                     any Subaccount must be a whole number not less than 5%, and
                     the sum of the allocation percentages must be 100%.

                     b.   Initial Premiums. Any portion of the initial Net 
                     Premium and any subsequent premiums received by National
                     Life before 20 days after the Date of Issue of a Policy,
                     that are to be allocated to the Separate Account will be
                     allocated to the Money Market Subaccount. At the end of
                     such period, National Life will allocate the amount in the
                     Money Market Subaccount to each of the Subaccounts selected
                     in the application based on the proportion that the
                     allocation percentage for such Subaccount bears to the sum
                     of the Separate Account premium allocation percentages.

                     c.   Additional Premiums.  Additional Net Premiums will be
allocated to the Accounts in accordance with the allocation percentages then in
effect on the Valuation Date that the premium is received in good order at the
Home Office, unless other instructions accompany the premium, in which case the
net premium will be allocated in accordance with those instructions. If those
instructions do not comply with National Life's allocation rules, crediting and
allocation will not be implemented until further instructions are received from
Owners.

II.    TRANSFERS AMONG SUB-ACCOUNTS

       A.     TRANSFERS AMONG THE ACCOUNTS. The Owner may transfer the
              Accumulated Value between and among the Subaccounts of the
              Separate Account and the General Account by making a written
              transfer request to National Life, or if the telephone transaction
              privilege has been elected, by telephone instructions to National
              Life. Transfers between and among the Subaccounts of the Separate
              Account and the General Account are made as of the Valuation Day
              that the request for transfer is received at the Home Office. The
              Owner may, at any time, transfer all or part of the amount in one
              of the Subaccounts of the Separate Account to another Subaccount
              and/or to the General Account.

                                      A-6
<PAGE>   7

                     One transfer in each Policy Year is allowed from the
              General Account to any or all of the Subaccounts of the Separate
              Account. The amount transferred from the General Account may not
              exceed the greater of 25% of the value of such account at the time
              of transfer, or $1,000. The transfer will be made as of the date
              National Life receives the written or telephone request at its
              Home Office.

                     Currently, an unlimited number of transfers are permitted
              without charge, and National Life has no current intent to impose
              a transfer charge in the foreseeable future. However, National
              Life reserves the right to change this policy so as to deduct a
              $25 transfer charge from each transfer in excess of the fifth
              transfer during any one Policy Year. If such a charge is adopted
              in the future, the following transfers will not be subject to a
              transfer charge and will not count against the five free transfers
              in any Policy Year: (1) transfers resulting from Policy loans, (2)
              the exercise of the special transfer whereby the Owner may
              transfer the entire Accumulated Value in the Separate Account to
              the General Account during the first two years following the
              Policy issue without regard to limits on free transfers, (3) the
              special transfer right whereby an Owner may transfer the portion
              of the Accumulated Value in a Subaccount the investment policy of
              which is changed, without regard to any limits on transfers or
              free transfers, and (4) the reallocation from the Money Market
              Subaccount following the 10-day period after the Date of Issue.
              All transfers requested during one Valuation Period are treated as
              one transfer transaction.

       B.     DOLLAR COST AVERAGING

              This feature permits an Owner to automatically transfer funds from
              the Money Market Subaccount to any other Subaccounts on a monthly
              basis.

              1.     Election of Dollar Cost Averaging. Dollar Cost Averaging 
              may be elected at issue by marking the appropriate box on the
              initial application and completing the appropriate instructions,
              or, after issue, by filling out similar information on a change
              request form and sending it by mail to the Home Office.

              2.     Operation of the Program. If this feature is elected, the
              amount to be transferred will be taken from the Money Market
              Subaccount and transferred to the Subaccount or Subaccounts
              designated to receive the funds, each month on the Monthly Policy
              Date (starting with the Monthly Policy Date next following the
              date that the reallocation of the Accumulated Value out of the
              Money Market Subaccount and into the other Subaccounts would
              normally have occurred after expiration of the 10-day free look
              period after the Owner receives the Policy), until the amount in
              the Money Market Fund is depleted. The minimum monthly transfer by
              Dollar Cost Averaging is $100, except for the transfer that
              reduces the amount in the Money Market Subaccount to zero. An
              Owner may discontinue Dollar Cost Averaging at any time by sending
              an appropriate change request form to the Home Office.

       C.     PORTFOLIO REBALANCING

              This feature permits an Owner to automatically rebalance the value
              in the Subaccounts on a semi-annual basis, based on the Owner's
              premium allocation percentages in effect at the time of the
              rebalancing.

                                      A-7
<PAGE>   8

              1.     Election of Portfolio Rebalancing. Portfolio rebalancing 
              may be elected at issue by marking the appropriate box on the
              initial application, or, after issue, by completing a change
              request form and sending it by mail to the Home Office.

              2.     Operation of the Program. In Policies utilizing Portfolio
              Rebalancing from the Date of Issue, an automatic transfer will
              take place that causes the percentages of the current values in
              each Subaccount to match the current premium allocation
              percentages, starting with the Monthly Policy Date six months
              after the Date of Issue, and then on each Policy Anniversary, and
              each Monthly Policy Date six months thereafter. Policies electing
              Portfolio Rebalancing after issue will have the first automated
              transfer occur as of the Valuation Date on or next following the
              date that the election is received at the Home Office, and
              subsequent rebalancing transfers will occur every six months from
              such date. An Owner may discontinue Portfolio Rebalancing at any
              time by submitting an appropriate change request form to the Home
              Office by mail.

                     In the event that an Owner changes the Policy's premium
              allocation percentages, Portfolio Rebalancing will automatically
              be discontinued unless the Owner specifically directs otherwise.


III.   "REDEMPTION" PROCEDURES: SURRENDERS, WITHDRAWALS, DEATH BENEFITS, AND
       LOANS

       A.     "FREE-LOOK" PERIOD

              The Policy provides for an initial "free-look" period. The Owner
              may cancel the Policy before the latest of: (a) 45 days after Part
              A of the application for the Policy is signed; (b) 10 days after
              the Owner receives the Policy; and (c) 10 days after National Life
              mails or personally delivers a Notice of Withdrawal Right
              described in Section III.B. below to the Owner. Upon returning the
              Policy to National Life or to an agent of National Life within
              such time with a written request for cancellation, the Owner will
              receive a refund equal to the gross premiums paid on the Policy.

       B.     NOTICE OF WITHDRAWAL RIGHT REQUIRED BY RULE 6e-3(T)(b)(13)(viii)

              Upon issuance of a Policy, National Life will send by first class
              mail or personal delivery to the Policy Owner a written document
              containing (i) a notice of the right to return the Policy to
              National Life or to an agent of National Life before the latest
              of: (a) 45 days after Part A of the application for the Policy is
              signed; (b) 10 days after the Owner receives the Policy; and (c)
              10 days after National Life mails such notice of the right to
              return the Policy to the Owner; (ii) a statement of Policy fees
              and other charges; and (iii) a form of request for refund of gross
              premiums paid on the Policy setting forth (a) instructions as to
              the manner in which a refund may be obtained, including the
              address to which the request form should be mailed; and (b) spaces
              necessary to indicate the date of such request, the Policy number,
              and the signature of the Policy Owner. In a separate document,
              National Life will provide the Policy Owner with an illustration
              of Planned Periodic Premiums, death benefits and cash surrender
              values applicable to the age, sex, and Rate Class of the Insured.

       C.     REQUEST FOR CASH SURRENDER VALUE



                                      A-8
<PAGE>   9

              1.     Requests for Cash Surrender Value Permitted. At any time
              before the death of the Insured, the Owner may surrender the
              Policy for its Cash Surrender Value. The Cash Surrender Value is
              the Accumulated Value minus any Policy loan and accrued interest
              and less any applicable Surrender Charge. The Cash Surrender Value
              will be determined by National Life on the date it receives, at
              the Home Office, a written surrender request signed by the Owner,
              and the Policy. A surrender may not be requested over the
              telephone. Coverage under the Policy will end on the day the Owner
              mails or otherwise sends the written surrender request and the
              Policy to National Life. Surrender proceeds will ordinarily be
              mailed by National Life to the Owner within seven days of receipt
              of the request, unless a payment option was selected (see Section
              III.H. below).

              2.     Surrender of Policy -- Surrender Charges. A Surrender
              Charge, which consists of a Deferred Administrative Charge and a
              Deferred Sales Charge, is imposed if the Policy is surrendered or
              lapses at any time before the end of the fifteenth Policy Year.
              This Surrender Charge is designed partially to compensate National
              Life for the cost of administering and selling the Policy,
              including agent sales commissions, the cost of printing the
              prospectuses and sales literature, and any advertising and
              underwriting costs.

                     a.   Deferred Administrative Charge. The Deferred
                     Administrative Charge varies by Issue Age, and is based on
                     Initial Face Amount. After the first five Policy Years, it
                     declines linearly by Policy Month until the end of Policy
                     Year 15, when it becomes zero. Charges per $1,000 of Face
                     Amount for sample Issue Ages are shown below:

<TABLE>
<CAPTION>
                      Sample
                      Issue Age   Charge per $1000 of Initial Face Amount
                      ---------   ---------------------------------------
<S>                    <C>                      <C>    
                        0-5                      None
                         10                     $0.50
                         15                     $1.00
                         20                     $1.50
                       25-85                    $2.00
</TABLE>

                            For Issue Ages not shown, the charge will increase
                     by a ratable portion for each full year.

                     b.     Deferred Sales Charge. The Deferred Sales Charge 
                     will not exceed the Maximum Deferred Sales Charge specified
                     in the Policy. During Policy Years 1 through 5, this
                     maximum equals 50% of the Surrender Charge target premium
                     (which is an amount, based on the Initial Face Amount,
                     Issue Age, sex and Rate Class of the Insured, used solely
                     for the purpose of calculating the Deferred Sales Charge)
                     for the Face Amount. Thereafter, the 50% amount declines
                     linearly by month until the end of Policy Year 15, after
                     which it is zero. The Maximum Deferred Sales Charge will
                     also be subject to the maximum imposed by New York State
                     law, where applicable. The Deferred Sales Charge actually
                     imposed will equal the lesser of this maximum and an amount
                     equal to 30% of the premiums actually received up to one
                     Surrender Charge target premium, plus 10% of all premiums
                     paid in excess of this amount but not greater 


                                      A-9
<PAGE>   10

                     than twice this amount, plus 9% of all premiums paid in
                     excess of twice this amount.

              3.     Maturity. Policies issued in New York, Texas and Maryland
                     will mature on the Policy Anniversary at which the Insured
                     is Attained Age 99. At that time, National Life will pay
                     the Cash Surrender Value to the Owner in one sum unless a
                     Payment Option is chosen, and the Policy will terminate.

       D.     REQUEST FOR WITHDRAWALS

              1.     When Withdrawals are Permitted. At any time before the 
              death of the Insured and, except for employee benefit plans, after
              the first Policy Anniversary, the Owner may withdraw a portion of
              the Policy's Cash Surrender Value, subject to the following
              conditions:

              -      The minimum amount which may be withdrawn is $500, except
                     for employee benefit plans, where the minimum is $100.

              -      The maximum Withdrawal is the Cash Surrender Value minus
                     three times the Monthly Deduction for the most recent
                     Monthly Policy Date. A Withdrawal Charge will be deducted
                     from the amount of the Withdrawal.

              -      Withdrawals may be requested only by sending a written
                     request, signed by the Owner, to National Life at its Home
                     Office. A Withdrawal may not be requested over the
                     telephone.

              2.     Withdrawal Charge. At the time of a Withdrawal, National 
              Life will assess a charge equal to the lesser of 2% of the
              Withdrawal amount and $25. This Withdrawal Charge will be deducted
              from the Withdrawal amount.

              3.     Allocation of Withdrawals. The Withdrawal will be taken 
              from the Subaccounts of the Separate Account based upon the
              instructions of the Owner at the time of the Withdrawal. If
              specific allocation instructions have not been received from the
              Owner, the Withdrawal will be allocated to the Subaccounts based
              on the proportion that each Subaccount's value bears to the total
              Accumulated Value in the Separate Account. If the Accumulated
              Value in one or more Subaccounts is insufficient to carry out the
              Owner's instructions, the Withdrawal will not be processed until
              further instructions are received from the Owner. Withdrawals will
              be taken from the General Account only to the extent that
              Accumulated Value in the Separate Account is insufficient.

              4.     Effect of a Withdrawal on Face Amount. The effect of a
              Withdrawal on the Death Benefit and Face Amount will vary
              depending upon the Death Benefit Option in effect and whether the
              Unadjusted Death Benefit is based on the applicable percentage of
              Accumulated Value.

                     a.      Option A. If the Face Amount divided by the 
                     applicable percentage of Accumulated Value exceeds the
                     Accumulated Value just after the Withdrawal, a Withdrawal
                     will reduce the Face Amount and the Unadjusted Death
                     Benefit by the lesser of such excess and the amount of the
                     Withdrawal, effective on the date of the Withdrawal. If the
                     Face Amount divided by the applicable percentage of
                     Accumulated Value does 


                                      A-10
<PAGE>   11

                     not exceed the Accumulated Value just after the Withdrawal,
                     then the Face Amount is not reduced. The Unadjusted Death
                     Benefit will be reduced by an amount equal to the reduction
                     in Accumulated Value times the applicable percentage (or
                     equivalently, the Unadjusted Death Benefit is equal to the
                     new Accumulated Value times the applicable percentage).

                     b.      Option B. The Face Amount will never be decreased
                     by a Withdrawal. A Withdrawal will, however, always
                     decrease the Death Benefit. If the Unadjusted Death Benefit
                     equals the Face Amount plus the Accumulated Value, a
                     Withdrawal will reduce the Accumulated Value by the amount
                     of the Withdrawal, and thus the Unadjusted Death Benefit
                     will also be reduced by the amount of the Withdrawal. If
                     the Unadjusted Death Benefit immediately prior to the
                     Withdrawal is based on the applicable percentage of
                     Accumulated Value, the Unadjusted Death Benefit will be
                     reduced to equal the greater of (a) the Face Amount plus
                     the Accumulated Value after deducting the amount of the
                     Withdrawal and (b) the applicable percentage of Accumulated
                     Value after deducting the amount of the Withdrawal.

              5.     Other Effects of Withdrawals. Any decrease in Face Amount
              due to a Withdrawal will first reduce the most recent increase in
              Face Amount, then the most recent increases, successively, and
              lastly, the Initial Face Amount. Because a Withdrawal can affect
              the Face Amount (or increase in Face Amount) and the Unadjusted
              Death Benefit as described above, a Withdrawal may also affect the
              Net Amount(s) at Risk that is used to calculate the Cost of
              Insurance Charge(s) under the Policy. Since a Withdrawal reduces
              the Accumulated Value, the Cash Surrender Value of the Policy is
              reduced, thereby increasing the likelihood that the Policy will
              lapse.

              6.     When a Withdrawal Is Not Permitted. A request for 
              Withdrawal may not be allowed if such Withdrawal would reduce the
              Face Amount below the Minimum Face Amount for the Policy. Also, if
              a Withdrawal would result in cumulative premiums exceeding the
              maximum premium limitations applicable under the Code for life
              insurance, National Life will not allow the Withdrawal.

       E.     MONTHLY DEDUCTIONS

              On the Date of Issue and on each Monthly Policy Date, a redemption
              will be made from Accumulated Value for the Monthly Deduction,
              which is a charge compensating National Life for administrative
              expenses and for the insurance coverage provided by the Policy.
              The Monthly Deduction consists of three components: (a) the Cost
              of Insurance Charge, (b) the Monthly Administrative Charge, and
              (c) the cost of any additional benefits provided by rider. These
              charges are discussed in more detail in Appendix A hereto. Because
              portions of the Monthly Deduction, such as the Cost of Insurance
              Charge, can vary from month to month, the Monthly Deduction may
              vary in amount from month to month. The Monthly Deduction will be
              deducted on a pro rata basis from the Subaccounts of the Separate
              Account and the General Account, unless the Owner has elected at
              the time of application, or later requests in writing, that the
              Monthly Deduction be made from the Money Market Subaccount. If a
              Monthly Deduction cannot be made from the Money Market Subaccount,
              when that has been elected, the amount of the deduction in excess
              of the Accumulated Value available in the 


                                      A-11
<PAGE>   12

              Money Market Subaccount will be made on a pro rata basis from the
              Subaccounts of the Separate Account and the General Account.

       F.     DEATH BENEFITS

              1.     Payment of Death Benefit. As long as the Policy remains in
              force, the Death Benefit of the Policy will, upon the Company's
              receipt of due proof of the Insured's death and a Claimant's
              Statement signed by or on behalf of the Beneficiary, as well as
              any other necessary documentation, be paid to the named
              Beneficiary in accordance with the designated Death Benefit
              Option, unless the claim is contestable in accordance with the
              terms of the Policy. The proceeds may be paid in cash or under one
              of the Settlement Options set forth in the Policy. The amount
              payable under the designated Death Benefit Option will be
              increased by any additional benefits, any dividend payable, and by
              interest from the date of the Insured's death to the payment date
              at a National Life declared interest rate or any higher legal
              requirement, and will be decreased by any outstanding Policy loan
              and accrued interest and by any unpaid Monthly Deductions.

              2.     Death Benefit Options. The Policy provides two Death 
              Benefit Options: Option A and Option B. The Owner designates the
              Death Benefit Option in the application and may change it as
              described below. At Attained Age 99, Option B automatically
              becomes Option A.

                     a.  Option A. The Unadjusted Death Benefit is equal to the
                     greater of (a) the Face Amount of the Policy and (b) the
                     Accumulated Value on the Valuation Date on or next
                     following the Insured's date of death multiplied by the
                     specified percentage shown in the table below. For Attained
                     Ages not shown, the percentages will decrease by a ratable
                     portion of each full year.

</TABLE>

                     b.  Option B. The Unadjusted Death Benefit is equal to the
                     greater of (a) the Face Amount of the Policy plus the
                     Accumulated Value and (b) the Accumulated Value on the
                     Valuation Date on or next following the Insured's date of
                     death multiplied by the specified percentage shown in the
                     table above.

              3.     Change in Death Benefit Option. After the first Policy 
              Year, the Death Benefit Option in effect may be changed by sending
              National Life a written request. No charges will be imposed to
              make a change in the Death Benefit Option. The effective date of
              any such change will be the Monthly Policy Date on 


                                      A-12
<PAGE>   13

              or next following the date National Life receives the written
              request. Only one change in Death Benefit Option is permitted in
              any one Policy Year.

                     -      If the Death Benefit Option is changed from Option A
                            to Option B, on the effective date of the change,
                            the Death Benefit will not change but the Face
                            Amount will be decreased by the Accumulated Value on
                            that date. However, this change may not be made if
                            it would reduce the Face Amount to less than the
                            Minimum Face Amount.

                     -      If the Death Benefit Option is changed from Option B
                            to Option A, on the effective date of the change,
                            the Death Benefit will not change but the Face
                            Amount will be increased by the Accumulated Value on
                            that date.

                     -      A change in the Death Benefit Option may affect the
                            Net Amount at Risk over time which, in turn, would
                            affect the monthly Cost of Insurance Charge.
                            Changing from Option A to Option B will generally
                            result in a Net Amount at Risk that remains level.
                            Such a change will result in a relative increase in
                            the Cost of Insurance Charges over time because the
                            Net Amount at Risk will, unless the Unadjusted Death
                            Benefit is based on the applicable percentage of
                            Accumulated Value, remain level as cost of insurance
                            rates increase over time, rather than the Net Amount
                            at Risk decreasing as the Accumulated Value
                            increases. Changing from Option B to Option A will,
                            if the Accumulated Value increases, decrease the Net
                            Amount at Risk over time, thereby partially
                            offsetting the effect of increases and over time in
                            the Cost of Insurance Charge to the extent the
                            decrease in Net Amount at Risk more than offsets the
                            increase in rates as the Insured ages.

                     -      If a change in the Death Benefit Option would result
                            in cumulative premiums exceeding the maximum premium
                            limitations under the Internal Revenue Code for life
                            insurance, National Life will not effect the change.

              4.     How the Death Benefit May Vary. The amount of the Death 
              Benefit may vary with the Accumulated Value. The Death Benefit
              under Option A will vary with the Accumulated Value whenever the
              specified percentage of Accumulated Value exceeds the Face Amount
              of the Policy. The Death Benefit under Option B will always vary
              with the Accumulated Value because the Unadjusted Death Benefit
              equals the greater of (a) the Face Amount plus the Accumulated
              Value and (b) the Accumulated Value multiplied by the specified
              percentage.

              5.     Ability to Adjust Face Amount. Subject to certain 
              limitations, an Owner may generally, at any time after the first
              Policy Year, increase or decrease the Policy's Face Amount by
              submitting a written application to National Life. The effective
              date of an increase will be the Monthly Policy Date on or next
              following National Life's approval of the request, and the
              effective date of a decrease is the Monthly Policy Date on or next
              following the date that National Life receives the written
              request. Employee benefit plan Policies may adjust the Face Amount
              even in Policy Year 1. The effect of changes in Face Amount on
              Policy charges, as well as other considerations, are described
              below.

                                      A-13
<PAGE>   14

                     a.     Increase. A request for an increase in Face Amount 
                     may not be for less than $25,000, or such lesser amount
                     required in a particular state (except that the minimum for
                     employee benefit plans is $2,000). The Owner may not
                     increase the Face Amount after the Insured's Attained Age
                     85. To obtain the increase, the Owner must submit an
                     application for the increase and provide evidence
                     satisfactory to National Life of the Insured's
                     insurability.

                            On the effective date of an increase, and taking the
                     increase into account, the Cash Surrender Value must be
                     equal to the Monthly Deductions then due. If the Cash
                     Surrender Value is not sufficient, the increase will not
                     take effect until the Owner makes a sufficient additional
                     premium payment to increase the Cash Surrender Value to the
                     required level.

                            An increase in the Face Amount will generally have
                     the effect of increasing the total Net Amount at Risk,
                     which in turn will increase the monthly Cost of Insurance
                     Charges. In addition, the Insured may be in a different
                     Rate Class as to the increase in insurance coverage.

                     b.     Decrease. The amount of the Face Amount after a 
                     decrease (a) cannot be less than 75% of the largest Face
                     Amount in force at any time in the twelve months
                     immediately preceding National Life's receipt of the
                     request and (b) may not be less than the Minimum Face
                     Amount, which is generally $50,000. To the extent a
                     decrease in the Face Amount could result in cumulative
                     premiums exceeding the maximum premium limitations
                     applicable for life insurance under the Internal Revenue
                     Code, National Life will not effect the decrease.

                            A decrease in the Face Amount generally will
                     decrease the total Net Amount at Risk, which generally will
                     decrease an Owner's monthly Cost of Insurance Charges.

                            For purposes of determining the Cost of Insurance
                     Charge, any decrease in the Face Amount will reduce the
                     Face Amount in the following order: (a) the Face Amount
                     provided by the most recent increase; (b) the next most
                     recent increases, successively; and (c) the Initial Face
                     Amount.

       G.     LOANS

              1.     When Loans are Permitted. An Owner may at any time after 
              the first anniversary of the Date of Issue borrow money from 
              National Life using the Policy as the only security for the loan. 
              The Owner may obtain Policy loans in an amount not exceeding the 
              Policy's Cash Surrender Value on the date of the loan, minus 
              three times the Monthly Deduction for the most recent Monthly 
              Policy Date. While the Insured is living, the Owner may repay all 
              or a portion of a loan and accrued interest. Loans may be taken 
              by making a written request to National Life at the Home Office, 
              or, if the telephone transaction privilege has been elected, by 
              providing telephone instructions to National Life at the Home 
              Office. National Life limits the amount of a Policy loan taken 
              pursuant to telephone instructions to $10,000.

              2.     Interest Rate Charged. The interest rate charged on Policy
              loans will be at the fixed rate of 6% per year. Interest is
              charged from the date of the loan and is due at the end of each
              Policy Year. If interest is not paid when due, it will be added to
              the loan balance and bear interest at the same rate.

              3.     Allocation of Loans and Collateral. When a Policy loan is
              taken, Accumulated Value is transferred to and held in the General
              Account as Collateral for the Policy loan. Accumulated Value to be
              held as Collateral is taken from the Subaccounts of the Separate
              Account based upon the instructions of the Owner at the time the
              loan is taken. If specific allocation instructions have not been
              received from the Owner, Accumulated Value to be held as
              Collateral will taken from the Subaccounts based on the proportion
              that each Subaccount's value bears to the total Accumulated Value
              in the Separate Account. If the Accumulated Value in one or more
              of the Subaccounts is insufficient to carry out the Owner's
              instructions, the loan will not be processed until further
              instructions are received from the Owner. Non-loaned Accumulated
              Value in the General Account will become Collateral for a loan
              only to the extent that the Accumulated Value in the Separate
              Account is insufficient. Any loan interest due and unpaid will be
              allocated among and transferred first from the Subaccounts of the
              Separate Account in proportion to the Accumulated Values held in
              the Subaccounts, and then from the General Account.

                     The Collateral for a Policy loan will initially be equal to
              the loan amount. Any loan interest due and unpaid will be added to
              the Collateral for the Policy loan. National Life will take
              additional Collateral for the loan interest so added pro rata from
              the Subaccounts of the Separate Account, and then, if the amounts
              in the Separate Account are insufficient, from the portion of the
              General Account not held as Collateral, and hold the Collateral in
              the General Account. At any time, the amount of the outstanding
              loan under a Policy equals the sum of all loans (including due and
              unpaid interest added to the loan balance) minus any loan
              repayments.

              4.     Interest Credited to Amounts Held as Collateral. As long 
              as the Policy is in force, National Life will credit the amount in
              the General Account as Collateral with interest at effective
              annual rates it determines, but not less than 4% or such higher
              minimum rate required under state law. The rate will apply to the
              calendar year that follows the date of determination.

                                      A-15
<PAGE>   16

              5.     Bonus. In Policy Years 11 and thereafter, National Life
              currently intends to credit interest on the amount in the General
              Account as Collateral at a rate 0.50% per annum higher than for
              similar amounts for Policies still in their first ten Policy
              Years. Continuation of this bonus loan interest crediting is not
              guaranteed, however.

              6.     Preferred Policy Loans. National Life currently intends, 
              but is not obligated to continue, to make preferred Policy loans
              available, on the later of the Insured's Attained Age 65 and the
              beginning of Policy Year 21, in maximum amounts of 5% of
              Accumulated Value per year, subject to a cumulative maximum of 50%
              of Accumulated Value. For such preferred Policy loans, amounts
              held as Collateral in the General Account will be credited with
              interest at an annual rate of 6%. If both preferred and
              non-preferred loans exist at the same time, any loan repayment
              will be applied first to the non-preferred loan.

              7.     Effect of Policy Loan. Policy loans, whether or not repaid,
              will have a permanent effect on the Accumulated Value and the Cash
              Surrender Value, and may permanently affect the Death Benefit
              under the Policy. The effect on the Accumulated Value and Death
              Benefit could be favorable or unfavorable, depending on whether
              the investment performance of the Subaccounts and the interest
              credited to the non-loaned Accumulated Value in the General
              Account is less than or greater than the interest being credited
              on the amounts held as Collateral in the General Account while the
              loan is outstanding. Compared to a Policy under which no loan is
              made, values under a Policy will be lower when the credited
              interest rate is less than the investment experience of assets
              held in the Separate Account and interest credited to the
              non-loaned Accumulated Value in the General Account. The longer a
              loan is outstanding, the greater the effect a Policy loan is
              likely to have. The Death Benefit will be reduced by the amount of
              any outstanding Policy loan.

       H.     SETTLEMENT OPTIONS

              In lieu of a single sum payment on death or surrender, an election
              may be made to apply the amount under any one of the fixed benefit
              Settlement Options provided in the Policy.

       I.     DELAY IN REDEMPTIONS OR TRANSFERS

              Any amounts payable as a result of surrender, Withdrawal, or
              Policy loan will ordinarily be paid within seven days of receipt
              of written request at National Life's Home Office in a form
              satisfactory to National Life. Generally, the amount of a payment
              will be determined as of the date of receipt by National Life of
              all required documents. However, National Life may defer the
              determination or payment of such amounts if the date for
              determining such amounts falls within any period during which: (1)
              the disposal or valuation of a Subaccount's assets is not
              reasonably practicable because the New York Stock Exchange is
              closed or conditions are such that, under the SEC's rules and
              regulations, trading is restricted or an emergency is deemed to
              exist; or (2) the SEC by order permits postponement of such
              actions for the protection of National Life policyholders.
              National Life also may defer the determination or payment of
              amounts from the General Account for up to six months. National
              Life may postpone any payment under the Policy derived from an
              amount paid by check or draft until National 


                                      A-16
<PAGE>   17

              Life is satisfied that the check or draft has been paid by the
              bank upon which it was drawn.

       J.     24-MONTH CONVERSION RIGHT

The conversion right required by Rule 6e-3(T)(b)(13)(v)(B) is provided by
permitting Policy Owners during the first two years following Policy issue and
on one occasion, to transfer the entire Accumulated Value in the Separate
Account to the General Account, without regard to any limits on transfers or
free transfers. Since a new policy, under which payments (or charges),
dividends, and cash values could vary from those under the existing Policy, will
not be issued, no adjustment in payments and cash values under the Policy would
be required to address such variances.

       K.     ACCELERATED BENEFITS RIDER

If an Owner has included in a Policy an Accelerated Benefits Rider, and then a
qualifying condition exists, the Owner may elect to receive a reduced death
benefit prior to the death of the Insured. The qualifying conditions are either
terminal illness or covered chronic illness, each as defined in the rider. When
an Owner elects an accelerated benefit, National Life will determine the amount
of the benefit, based on the qualifying condition on which payment is based, the
cash surrender value of the policy, future premiums payable under the policy,
charges under the policy, and an interest rate National Life declares.

The rider may be included in a Policy at issue or added after issue, for
Insureds ages 0-85; however, no benefit will be paid under the rider to an
Insured who has a covered chronic illness at the time the rider is issued, until
at least five years after the issue of the rider. The maximum amount payable
under the rider is $500,000.

   
If the rider applies to a Policy, it may be elected in whole or in part. If the
Owner chooses a Partial Election, the amount paid will be in lieu of a specified
portion of the Death Benefit. There will be a pro rata reduction in the
Accumulated Value and Cash Surrender Value in the unloaned portion of the
General Account and each Subaccount of the Separate Account at the time of a
Partial Election of the Accelerated Benefits Rider.
    

   
                                   APPENDIX A
    

       Charges will be deducted from the Accumulated Value on the Date of Issue
and on each Monthly Policy Date to compensate National Life for administrative
expenses and for the insurance coverage provided by the Policy. The Monthly
Deduction consists of three components: (a) the Cost of Insurance Charge, (b)
the Monthly Administrative Charge, and (c) the cost of any additional benefits
provided by rider. Because portions of the Monthly Deduction, such as the Cost
of Insurance Charge, can vary from month to month, the Monthly Deduction may
vary in amount from month to month. The Monthly Deduction will be deducted on a
pro rata basis from the Subaccounts of the Separate Account and the General
Account, unless the Owner has elected at the time of application, or later
requests in writing, that the Monthly Deduction be made from the Money Market
Subaccount. If a Monthly Deduction cannot be made from the Money Market
Subaccount, when that has been elected, the amount of the deduction in excess of
the Accumulated Value available in the Money Market Subaccount will be made on a
pro rata basis from the Subaccounts of the Separate Account and the General
Account.

                                      A-17
<PAGE>   18

       Cost of Insurance Charge. Because the Cost of Insurance Charge depends
upon several variables, the Cost of Insurance Charge payable on each Monthly
Policy Date can vary. National Life will determine the monthly Cost of Insurance
Charge by multiplying the applicable cost of insurance rate or rates by the
corresponding Net Amount at Risk for each Policy Month.

       The Net Amount at Risk on any Monthly Policy Date is the amount by which
the Unadjusted Death Benefit on the Monthly Policy Date adjusted by a factor
exceeds the Accumulated Value. This factor is 1.00327234, and is used to reduce
the Net Amount at Risk, solely for purposes of computing the Cost of Insurance
Charge, by taking into account assumed monthly earnings at an annual rate of
4.0%. The Net Amount at Risk is determined separately for the Initial Face
Amount and any increases in Face Amount. In determining the Net Amount at Risk
for each increment of Face Amount, the Accumulated Value is first considered
part of the Initial Face Amount. If the Accumulated Value exceeds the Initial
Face Amount, it is considered as part of any increases in Face Amount in the
order such increases took effect.

       The applicable cost of insurance rate depends on the Rate Class to which
the Insured was assigned. A Rate Class for any increase may differ from that for
the initial Face Amount. The rate for the Rate Class on the Date of Issue is
applied to the Net Amount at Risk for the Initial Face Amount. For each increase
in Face Amount, the rate for the Rate Class applicable to the increase is used.
If, however, the Unadjusted Death Benefit is calculated as the Accumulated Value
times the specified percentage, the rate for the Rate Class for the Initial Face
Amount will be used for the amount of the Unadjusted Death Benefit in excess of
the total Face Amount.

       Cost of Insurance Rate. The cost of insurance rate will be based on the
Issue Age, sex, Rate Class of the Insured, Policy Duration and Policy size. In
addition, any change in the Net Amount at Risk will affect the total Cost of
Insurance Charges paid by the Owner. The actual monthly cost of insurance rates
("current rates") will be based on National Life's expectations as to future
mortality and expense experience. They will not, however, be greater than the
guaranteed maximum cost of insurance rates set forth in the Policy. These
guaranteed maximum rates are based on the Insured's Attained Age, sex, Rate
Class, and the 1980 Commissioners Standard Ordinary Smoker/Nonsmoker Mortality
Table. For Policies issued in states which require "unisex" policies or in
conjunction with employee benefit plans, the maximum Cost of Insurance Charge
depends only on the Insured's Attained Age, Rate Class and the 1980
Commissioners Standard Ordinary Mortality Tables NB and SB. Any change in the
cost of insurance rates will apply to all persons of the same Issue Age, sex,
and Rate Class, Policy Duration and Policy size.

       Policies may also be issued on a guaranteed issue basis, where no medical
underwriting is required prior to issuance of a Policy. Current cost of
insurance rates for Policies issued on a guaranteed issue basis may be higher
than current cost of insurance rates for healthy Insureds who undergo medical
underwriting.

       Rate Class. The Rate Class of the Insured will affect the guaranteed and
current cost of insurance rates. National Life currently places Insureds into
preferred nonsmoker, standard nonsmoker, smoker, juvenile classes, and
substandard classes, which reflect higher mortality risks.

       Since the nonsmoker designation is not available for Insureds under
Attained Age 20, shortly before an Insured attains age 20, National Life will
notify the Insured about possible classification as a nonsmoker and direct the
Insured to his or her agent to initiate a change in Rate Class. If the Insured
either does not initiate a change in Rate Class or does not qualify as a


                                      A-18
<PAGE>   19

nonsmoker, guaranteed cost of insurance rates will remain as shown in the
Policy. However, if the Insured qualifies as a nonsmoker, the guaranteed and
current cost of insurance rates will be changed to reflect the nonsmoker
classification.

       Current cost of insurance rates will also vary by Policy size, in the
following bands: those with Unadjusted Death Benefits less than $250,000; those
with Unadjusted Death Benefits between $250,000 and $999,999, inclusive; and
those with Unadjusted Death Benefits of $1,000,000 and over. Cost of insurance
rates will be lower as the Policy size band is larger.

       Monthly Administrative Charge. National Life administers the Policy and
the Separate Account and, therefore, will incur certain ordinary administrative
expenses. National Life therefore assesses a Monthly Administrative Charge. The
Monthly Administrative Charge of $7.50 will be deducted from the Accumulated
Value on the Date of Issue and each Monthly Policy Date as part of the Monthly
Deduction. This charge is intended to reimburse National Life for ordinary
administrative expenses expected to be incurred, including record keeping,
processing claims and certain Policy changes, preparing and mailing reports, and
overhead costs. National Life does not expect to make a profit on this charge.

       Optional Benefit Charges. The Monthly Deduction will include charges for
any additional benefits added to the Policy. The monthly charges will be
specified in the applicable Rider. The following optional benefits, which are
subject to the restrictions and limitations set forth in the applicable Policy
Riders, may be included in a Policy at the option of the Owner:

          Waiver of Monthly Deductions. The Waiver of Monthly Deductions Rider
will waive Monthly Deductions against the Policy if the Insured becomes totally
disabled, before age 65 and for at least 120 days. If total disability occurs
after age 60 and before age 65, then Monthly Deductions will be waived only
until the Insured reaches Attained Age 65, or for a period of two years, if
longer. The monthly cost of this Rider is based on sex-distinct rates multiplied
by the Monthly Deduction on the Policy, and will be added to the Monthly
Deduction on the Policy.

          Accidental Death Benefit. The Accidental Death Rider provides for an
increased Death Benefit in the event that the Insured dies in an accident.

          Guaranteed Insurability Option. This Rider will permit the Owner to
increase the Face Amount of the Policy, within certain limits, without being
required to submit satisfactory proof of insurability at the time of the request
for the increase.

          Guaranteed Death Benefit. If this Rider is elected, National Life will
guarantee that the Policy will not lapse prior to the Insured's Attained Age 70,
or 20 years from the Date of Issue of the Policy, if longer, regardless of the
Policy's investment performance. To keep this Rider in force, cumulative
premiums paid must be greater than the Minimum Guarantee Premium from the Date
of Issue. The Policy will be tested monthly for this qualification, and if not
met, a notice will be sent to the Owner, who will have 61 days from the date the
notice is mailed to pay a premium sufficient to keep the Rider in force. The
premium required will be the Minimum Guarantee Premium from the Date of Issue,
plus two times the Minimum Monthly Premium, minus premiums previously paid. The
Rider will be cancelled if a sufficient premium is not paid during that 61-day
period.

          The cost of the Guaranteed Death Benefit Rider is $0.01 per thousand
of Face Amount per month. This Rider is available only at issue, and only for
Issue Ages 0-65.

                                      A-19
<PAGE>   20

          If while the Guaranteed Death Benefit Rider is in force, the
Accumulated Value of the Policy is not sufficient to cover the Monthly
Deductions, Monthly Deductions will be made until the Accumulated Value of the
Policy is exhausted, and will thereafter be deferred, and collected at such time
as the Policy has positive Accumulated Value.

          If the Face Amount of a Policy subject to the Guaranteed Death Benefit
Rider is increased, the Rider's guarantee will extend to the increased Face
Amount. This will result in an increased Minimum Guarantee Premium.

          If both the Waiver of Monthly Deductions Rider and the Guaranteed
Death Benefit Rider apply to a Policy and Monthly Deductions are waived because
of total disability, then Minimum Guarantee Premium required to keep the
Guaranteed Death Benefit Rider in force will be waived during the period that
Monthly Deductions are being waived.

          For Policies with the Guaranteed Death Benefit Rider, Withdrawals and
Policy loans will be limited to the excess of premiums paid over the Minimum
Guarantee premium, if the Owner wishes to keep the Rider in force. If a Policy
loan or Withdrawal for an amount greater than such excess is desired, the
Guaranteed Death Benefit Rider will enter a 61-day lapse-pending notification
period, and will be cancelled if a sufficient premium is not paid.

       Bonus. National Life currently intends to reduce the Monthly Deduction
starting in Policy Year 11 by an amount equal to 0.50% per annum of the
Accumulated Value in the Separate Account. Accumulated Value in the General
Account not held as Collateral will also be credited with interest at a rate
0.50% higher than the interest rate otherwise applicable, starting in Policy
Year 11. This bonus is not guaranteed, however, and will only be continued if
National Life's mortality and expense experience with the Policies justifies
continuation of the bonus.

National Life Insurance Company
National Life Drive
Montpelier, Vermont  05604


Dear Sirs:
   
         This opinion is furnished in connection with the filing of a
Post-Effective Amendment No. 5 to a Registration Statement on Form S-6
("Registration Statement") under the Securities Act of 1933, as amended, of
National Variable Life Insurance Account (the "Separate Account") and National
Life Insurance Company ("National Life"), covering an indefinite amount of
premiums expected to be received under certain flexible premium adjustable
benefit individual variable life insurance policies ("Policies") to be offered
by National Life.  Under the Policies, amounts will be allocated by National
Life to the Separate Account as described in the prospectuses included in the
Registration Statement to support reserves for such Policies.
    

         In my capacity as Senior Vice President and General Counsel of
National Life, I have examined all such corporate records of National Life and
such other documents and laws as I consider appropriate as a basis for the
opinion hereinafter expressed.  Based upon such examination, I am of the
opinion that:

         1.      National Life is a corporation duly organized and validly
existing under the laws of the State of Vermont.

         2.      The Separate Account has been duly created and is validly
existing as a separate account pursuant to Title 8, Vermont Statutes Annotated,
Sections 3855 to 3859.

         3.      The portion of the assets to be held in the Separate Account
equal to the reserves and other liabilities under the Policies is not
chargeable with liabilities arising out of any other business National Life may
conduct.

         4.      The Policies have been duly authorized by National Life and,
when issued as contemplated by the Registration Statement, will constitute
legal, validly issued and binding obligations of National Life in accordance
with their terms.

   
         I hereby consent to the use of this opinion as an exhibit to Post
Effective Ammendment No. 5 to the S-6 Registration Statement and to the
reference to my name under the heading "Legal Matters" in the prospectuses.
    

                                        Very truly yours,
   
                                        Michele S. Gatto
                                        Senior Vice President and
                                        General Counsel

                                                                      Exhibit 6

                                            April 30, 1999

Ladies and Gentlemen:

        In my capacity as Associate Actuary - Development of National Life
Insurance Company, I have provided actuarial advice concerning: (a) the
preparation of Post Effective Amendment No. 5 to a registration statement for
National Variable Life Insurance Account filed on Form S-6 with the Securities
and Exchange Commission under the Securities Act of 1933 (the "Registration
Statement") regarding the offer and sale of Flexible Premium Adjustable Benefit
Variable Life Insurance Policies (the "Policies"); and (b) the preparation of
policy forms for the Policies described in the Registration Statement.

        It is my professional opinion that:

        (1) The illustrations of Death Benefits, Cash Surrender Values, and
accumulated premiums in Appendix A of the prospectuses (the "Prospectuses")
contained in the Registration Statement, based on the assumptions stated in the
illustrations, are consistent with the assumptions stated in the Policies. The
rate structure of the Policies has not been designed so as to make the
relationship between premiums and benefits as shown in the illustrations, appear
to be correspondingly more favorable to the prospective purchasers of Policies,
who are male non-smokers age 40 in the preferred rate class, than to prospective
purchasers of Policies for males or females at other ages or other rate classes.

        (2) The information contained in the examples in the sections of the
prospectuses entitled "Detailed Description of Policy Provisions," "Charges and
Deductions," and "Policy Rights," based on the assumptions stated in the
examples, is consistent with the provisions of the Policies.

        I hereby consent to the filing of this opinion as an exhibit to Post
Effective Amendment No. 5 to the Registration Statement and the use of my name
under the heading "Experts" in the prospectuses contained in the Registration
Statement.

                                   Sincerely,

                                   Elizabeth H. MacGowan, F.S.A., M.A.A.A.
