                                    SUMMARY

      This summary provides a brief description of some of the features and
charges of the Contract. You will find more detailed information in the rest of
this Prospectus, the Statement of Additional Information and the Contract.
Please keep the Contract and its riders or endorsements, if any, together with
the application. Together they are the entire agreement between you and us.

HOW DO I PURCHASE A CONTRACT?

      Generally, you may purchase a Contract if you are age 85 and younger. See
"Issuance of a Contract," page _____. The initial Premium Payment must be at
least $5,000 for Non-Qualified Contracts, and generally must be at least $1500
for IRA's or Tax-Sheltered Annuities.

CAN I MAKE ADDITIONAL PREMIUM PAYMENTS?

      You may make additional Premium Payments at any time (except for Contracts
purchased in Oregon - see page ), but must be at least $100 ($50 for IRA's). We
may accept lower Premium Payments at our discretion if the Premium Payments are
remitted electronically. The total of all Premium Payments under Contracts
issued on the life of any one Annuitant may not exceed $1,000,000 without our
prior consent (see "Premium Payments," page _____).

HOW DOES THE "FREE LOOK" RIGHT TO EXAMINE THE CONTRACT WORK?

      To be sure that you are satisfied with the Contract, you have a ten day
free look right to examine the Contract. Some states may require a longer
period. Within ten days of the day you receive the Contract, you may return the
Contract to our Home Office at the address shown on the cover page of this
Prospectus. When we receive the Contract, we will void the Contract and refund
the Contract Value plus any charges assessed when the Contract was issued,
unless otherwise required by state and/or federal law.

      In the case of IRA's and Contracts issued in states that require the
return of Premium Payments, we will refund the greater of: (i) Premium Payments
or (ii) Contract Value plus any amount deducted for state premium taxes. In
these cases, we may require that all Contract Value allocated to the Variable
Account initially be held in the Market Street Money Market Subaccount (see
"Free Look," page _____). At the end of the free look period, we will allocate
Contract Value among the Subaccounts based on the allocation percentages you 
specify in the application. For this purpose, we assume the free look period 
ends 20 days after the date the Contract is issued.

WHAT IS THE PURPOSE OF THE VARIABLE ACCOUNT?

      The Variable Account is a separate investment account that consists of 27
Subaccounts. Before the Contract Value is applied to a payment option, amounts
in the Variable Account will vary according to the investment performance of the
Fund(s) in which your elected Subaccounts are invested. You may allocate Net
Premium Payments among the Fixed Account and the 27 Subaccounts of the Variable
Account. The assets of each Subaccount are invested in the corresponding
portfolios of the Funds that are listed on the cover page of this Prospectus
(see "The Variable Account" and "Underlying Fund Options," pages _____).

      We cannot give any assurance that any Subaccount will achieve its 
investment objectives. You bear the entire investment risk on the value of your
Contract which you allocate to the Variable Account. The value of your Contract
may be more or less than the premiums paid.

HOW DOES THE FIXED ACCOUNT WORK?

      You may allocate all or part of your Net Premium Payments or make
transfers from the Variable Account to the Fixed Account. Contract Value held
in the Fixed Account will earn an effective annual interest rate of at least
3.0% (see "The Fixed Account").

WHEN WILL I RECEIVE PAYMENTS?

      After the Contract Value is transferred to a payment option, we will pay
proceeds according to the Annuity Payment Option you select. If the Contract
Value at the Annuitization Date is less than $3,500, the Contract Value may be
distributed in one lump sum instead of annuity payments. If any annuity payment
would be less than $100, we have the right to change the frequency of payments
to intervals that will result in payments of at least $100. In no event will
annuity payments be less frequent than annually (see "Annuitization - Frequency
and Amount of Annuity Payments," page _____).

WHAT HAPPENS IF THE OWNER DIES BEFORE ANNUITIZATION?

      If (1) any Owner dies before the Contract Value is transferred to a
payment option ("Annuitization"); (2) the Enhanced Death Benefit Rider is not
elected; and (3) the Owner has not reached age 81, we will pay the Beneficiary
the greater of (a) the Contract Value, or (b) the Net Premium Payments made to
the Contract (less all withdrawals and applicable premium tax charge). For more
information, see "Death of Owner," page .

WHAT HAPPENS IF THE ANNUITANT DIES BEFORE ANNUITIZATION?

      If the Annuitant (who is not an Owner) dies before the Contract Value is
transferred to a payment option, we will pay the Beneficiary a Death Benefit
equal to the Cash Surrender Value, unless the Owner selects another available
option (see "Death of Annuitant Prior to the Annuitization Date," page ).

CAN I MAKE A WITHDRAWAL FROM MY CONTRACT?

      You may withdraw part or all of the Cash Surrender Value at any time
before the Contract is Annuitized (see "Surrender and Withdrawal," page ). A
Withdrawal or a Surrender may result in federal income tax, including a federal
penalty tax (see "Federal Income Tax Considerations," page ).

WHAT CHARGES WILL I PAY?

      Contingent Deferred Sales Charge: We do not deduct a sales charge from
Premium Payments. However, if you surrender the Contract or make a Withdrawal,
we will generally deduct from the Contract Value a Contingent Deferred Sales
Charge not to exceed 7% of the lesser of the total of all Net Premium Payments
made within 84 months prior to the date of the request to surrender or the
amount surrendered (see "Contingent Deferred Sales Charge," page ).

      Annual Contract Fee: We deduct an Annual Contract Fee of $30.00 payable on
the Date of Issue and at each Contract Anniversary thereafter as long as the
Contract Value is less than $50,000 (see "Annual Contract Fee," page ).

      Administration Charge: We also deduct an Administration Charge each day at
an annual rate of 0.15% from the assets of the Variable Account (see "Deductions
from the Variable Account," page ).

      Mortality and Expense Risk Charge: We deduct a mortality and expense risk
charge each day from the assets of the Variable Account at an annual rate of
1.25% (see "Deductions from the Variable Account," page ).

      Charge for Optional Enhanced Death Benefit Rider: If elected, we deduct an
annual charge of 0.20% of the Contract Value for this option (see "Charge for
Option Enhanced Death Benefit Rider," page ).

      Premium Taxes: If a governmental entity imposes premium taxes, we will
make a deduction for premium taxes in a corresponding amount. Certain states
impose a premium tax. Premium taxes may range up to 3.5% (see "Premium
Taxes," page ).

      Investment Management Fees: Charges for investment management services and
operating expenses are deducted daily from each portfolio of each Fund (see
"Underlying Fund Annual Expenses," page  and the accompanying Fund 
prospectuses).

ARE THERE ANY OTHER CONTRACT PROVISIONS?

      For information concerning other important Contract provisions, see
"Contract Rights and Privileges," page  and the remainder of this Prospectus.

HOW WILL THE CONTRACT BE TAXED?

      For a brief discussion of our current understanding of the federal tax
laws concerning us and the Contract, see "Federal Income Tax Considerations,"
page .

WHAT IF I HAVE QUESTIONS?

      We will be happy to answer your questions about the Contract or our
procedures. Call or write to us at the phone number or address on the cover
page. All inquiries should include the Contract number and the names of the
Owner and the Annuitant.

      If you have questions concerning your investment strategies, please
contact your registered representative.

(1) States may assess premium taxes on premiums paid under the Contract. Where
    National Life is required to pay this premium tax when a Premium Payment is
    made, it may deduct an amount equal to the amount of premium tax paid from
    the Premium Payment. National Life currently intends to make this deduction
    from Premium Payments only in South Dakota. In the remaining states which
    assess premium taxes, a deduction will be made only upon Annuitization,
    death of the Owner, or surrender. See "Premium Taxes", page .

(2) Each Contract Year, the Owner may withdraw without a Contingent Deferred
    Sales Charge (CDSC) an amount equal to 15% of the Contract Value as of the
    most recent Contract Anniversary. In addition, any amount withdrawn in order
    for the Contract to meet minimum Distribution requirements under the Code
    shall be free of CDSC. Withdrawals may be restricted for Contracts issued
    pursuant to the terms of a Tax-Sheltered Annuity. This CDSC-free Withdrawal
    privilege does not apply in the case of full surrenders and is
    non-cumulative; that is, free amounts not taken during any given Contract
    Year cannot be taken as free amounts in a subsequent Contract Year; in
    addition, certain states do not permit this CDSC-free Withdrawal provision,
    in which case a different CDSC-free Withdrawal provision will apply (see
    "Contingent Deferred Sales Charge", page ).

(3) The Annual Contract Fee is assessed only upon Contracts which as of the Date
    of Issue or applicable Contract Anniversary, have a Contract Value of less
    than $50,000 and is not assessed on Contract Anniversaries after the
    Annuitization Date.

(4) This charge, which applies to the Contract Value, is assessed only if the
    Owner has elected the Enhanced Death Benefit Rider. See "Optional Enhanced
    Death Benefit Rider", page .

(6) The Fund expenses shown above are assessed at the underlying Fund level and
are not direct charges against Variable Account assets or reductions from
Contract Values. These underlying Fund expenses are taken into consideration in
computing each underlying Fund's net asset value, which is the share price used
to calculate the unit values of the Variable Account. The management fees and
other expenses are more fully described in the prospectuses for each individual
underlying Fund. The information relating to the underlying Fund expenses was
provided by the underlying Fund and was not independently verified by National
Life. In the absence of any voluntary fee waivers or expense reimbursements, the
Management Fees, Other Expenses, and Total Expenses of the Funds listed below

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

NATIONAL LIFE INSURANCE COMPANY

      National Life 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 the outstanding stock of which 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 mortality and expense
risks under the Contracts and its assets support the Contract's benefits.
Financial Statements for National Life are contained in the Statement of
Additional Information.

THE VARIABLE ACCOUNT

      The Variable Account was established by National Life on November 1, 1996,
pursuant to the provisions of Vermont law. National Life has caused the Variable
Account to be registered with the Securities and Exchange Commission as a unit
investment trust pursuant to the provisions of the Investment Company Act. Such
registration does not involve supervision of the management of the Variable
Account or National Life by the Securities and Exchange Commission.

      The Variable Account is a separate investment account of National Life
and, as such, is not chargeable with liabilities arising out of any other
business National Life may conduct. National Life does not guarantee the
investment performance of the Variable Account. Obligations under the Contracts
are obligations of National Life. Income, gains and losses, whether or not
realized, from the assets of the Variable Account are credited to or charged
against the Variable Account without regard to other income, gains, or losses of
National Life.

      Net Premium Payments are allocated within the Variable Account among one
or more Subaccounts made up of shares of the Fund options designated by the
Owner. A separate Subaccount is established within the Variable Account for each
of the Fund options.

UNDERLYING FUND OPTIONS

      You may choose from among a number of different Subaccount options.
However, National Life reserves the right to limit the number of different
Subaccounts, other than the Market Street Money Market Subaccount, used in any 
Contract over its entire life to 16.

      Summary information, including the investment objectives for each of the
underlying Funds held in the Subaccounts is set forth below. THERE CAN BE NO
ASSURANCE THAT THE INVESTMENT OBJECTIVES WILL BE ACHIEVED.

      The investment objectives and policies of certain Funds are similar to the
investment objectives and policies of other mutual fund portfolios that may be
managed by the same investment adviser or manager. The investment results of the
Funds, 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 portfolios, even if the other portfolio has the same
investment adviser or manager.

    ALGER AMERICAN SMALL CAPITALIZATION PORTFOLIO

      Investment Objective: To seek long-term capital appreciation by investing
      in a diversified, actively managed portfolio of equity securities, at
      least 65% in companies with a total market capitalization within the range
      of companies included in the Russell 2000 Growth Index or the S&P SmallCap
      600 Index, updated quarterly (both of the above indexes are broad indexes
      of small capitalization stocks).

    ALGER AMERICAN GROWTH PORTFOLIO

      Investment Objective: To seek long-term capital appreciation by investing
      in a diversified, actively managed portfolio of equity securities, at
      least 65% in companies with a total market capitalization of $1 billion or
      greater.

FIDELITY VARIABLE INSURANCE PRODUCTS FUND

      The Fund is an open-end, diversified, management investment company.
Fidelity Management & Research Company ("FMR") is the Fund's manager.

     -EQUITY-INCOME PORTFOLIO

      Investment Objective: To seek reasonable income by investing primarily in
      income-producing equity securities. In choosing these securities FMR also
      will consider the potential for capital appreciation. The Portfolio's goal
      is to achieve a yield which exceeds the composite yield on the securities
      comprising the Standard & Poor's 500 Composite Stock Price Index.

     -GROWTH PORTFOLIO

      Investment Objective: Seeks to achieve capital appreciation. This
      Portfolio will invest in the securities of both well-known and established
      companies, and smaller, less well-known companies which may have a narrow
      product line or whose securities are thinly traded. These latter
      securities will often involve greater risk than may be found in the
      ordinary investment security. FMR's analysis and expertise plays an
      integral role in the selection of securities and, therefore, the
      performance of the Portfolio. Many securities which FMR believes would
      have the greatest potential may be regarded as speculative, and investment
      in the Portfolio may involve greater risk than is inherent in other
      underlying Funds. It is also important to point out that the Portfolio
      makes most sense for you if you can afford to ride out changes in the
      stock market, because it invests primarily in common stocks. FMR also can
      make temporary investments in securities such as investment-grade bonds,
      high-quality preferred stocks and short-term notes, for defensive purposes
      when it believes market conditions warrant.

     -HIGH INCOME PORTFOLIO

      Investment Objective: Seeks to obtain a high level of current income by
      investing primarily in high-risk, lower-rated, high-yielding, fixed-income
      securities, while also considering growth of capital. The Portfolio
      manager will seek high current income normally by investing the
      Portfolio's assets as follows:

                  - at least 65% in income-producing debt securities and
                    preferred stocks, including convertible securities; and

                  - up to 20% in common stocks and other equity securities when
                    consistent with the Portfolio's primary objective or
                    acquired as part of a unit combining fixed-income and equity
                    securities.

      The Portfolio's investment strategy may provide the opportunity for higher
      than average yields by investing in securities with higher than average
      risk, such as lower rated and unrated debt 



                                       17

      Debt Securities" section of the Portfolio's prospectus.

     -OVERSEAS PORTFOLIO

      Investment Objective: To seek long term growth of capital primarily

      Poor's' Composite Index of 500 Stocks ("S&P 500") while keeping expenses
      low. The Fund normally invests at least 80% of its assets in equity
      securities of companies that compose the S&P 500. Bankers Trust Company
      currently serves as sub-adviser to the Fund and manages the Fund's
      Portfolio.

      -CONTRAFUND PORTFOLIO

      Investment Objective: To seek capital appreciation by investing primarily
      in companies that the Fund manager believes to be undervalued due to an
      overly pessimistic appraisal by the public. This strategy can lead to
      investments in domestic or foreign companies, small and large, many of
      which may not be well known. The Fund primarily invests in common stock
      and securities convertible into common stock, but it has the flexibility
      to invest in any type of security that may produce capital appreciation.

    National Life has entered into or may enter into agreements with Funds
pursuant to which the adviser or distributor pays National Life a fee based upon
an annual percentage of the average net asset amount invested on behalf of the
Variable Account and our other separate accounts. These percentages may differ
and we may be paid a greater percentage by some investment advisers or
distributors than other advisers or distributors. These agreements reflect
administrative services we provide.

    The Funds may also be available to registered separate accounts offering
variable annuity and variable life products of other participating insurance
companies, as well as to the Variable Account 



                                       21
    

<PAGE>   28


   
and other separate accounts of National Life. Although we do not anticipate any
disadvantages to this, there is a possibility that a material conflict may arise
between the interest of the Variable Account and one or more of the other
separate accounts participating in the underlying Funds. A conflict may occur
due to a change in law affecting the operations of variable life and variable
annuity separate accounts, differences in the voting instructions of the Owners
and those of other companies, or some other reason. In the event of conflict, we
will take any steps necessary to protect Owners and variable annuity payees,
including withdrawal of the Variable Account from participation in the
underlying Fund or Funds which are involved in the conflict.

                    DETAILED DESCRIPTION OF CONTRACT PROVISIONS

ISSUANCE OF A CONTRACT

      The Contract is available to Owners up to and including age 85 on the Date
of Issue. If the Contract is issued to Joint Owners, then the oldest Joint Owner
must be 85 years of age or younger on the Date of Issue. If the Owner is not a
natural person, then the age of the Annuitant must meet the requirements for
Owners.

      In order to purchase a Contract, an individual must forward an application
to us through a licensed National Life agent who is also a registered
representative of Equity Services, Inc. ("ESI"), the principal underwriter of
the Contracts or another broker/dealer having a Selling Agreement with ESI or a
broker/dealer having a Selling Agreement with such a broker/dealer.

PREMIUM PAYMENTS

      The Initial Premium Payment. The initial Premium Payment must be at least
$5,000 for Non-Qualified Contracts, and in general must be at least $1500 for
Qualified Contracts. We may at our discretion permit initial Premium Payments
lower than these minimums. For Contracts purchased in South Carolina, the
initial Premium Payment for Qualified Contracts must be at least $3000.

      Subsequent Premium Payments. Subsequent Premium Payments may be made at
any time, but must be at least $100 ($50 for Individual Retirement Annuities).
We may accept lower Premium Payments at our discretion if the Premium Payments
are remitted electronically. We will price subsequent Premium Payments to the
Variable Account on the basis of the Accumulation Unit Value next computed for
the appropriate Subaccount after the additional Premium Payment is received. For
Contracts purchased in the State of Oregon, we are not permitted to accept
subsequent Premium Payments on or after the third Contract Anniversary.

      The total of all Premium Payments under Contracts issued on the life of
any one Annuitant may not exceed $1,000,000 without our prior consent.

      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.

      Allocation of Net Premium Payments. In the application for the Contract,
the Owner will indicate how Net Premium Payments are to be allocated among the
Subaccounts of the Variable Account and/or the Fixed Account. These allocations
may be changed at any time by the Owner by written notice to us at our Home
Office or, if the telephone transaction privilege has been elected, by telephone
instructions (see "Telephone Transaction Privilege", page ).

      The percentages of Net Premium Payments that may be allocated to any
Subaccount or the Fixed Account must be in whole numbers of not less than 5%,
and the sum of the allocation percentages must be 100%. We allocate the initial
Net Premium Payment within two business days after receipt, if the application
and all information necessary for processing the order are complete.




                                       22
    

<PAGE>   29

   

      If the application is not properly completed, we retain the initial
Premium Payment for up to five business days while attempting to complete the
application. If the application is not complete at the end of the five day
period, we inform the applicant of the reason for the delay and the initial
Premium Payment will be returned immediately, unless the applicant specifically
consents to our retaining the initial Premium Payment until the application is
complete. Once the application is complete, we allocate the initial Net Premium
Payment as designated by the Owner within two business days.

      Notwithstanding the foregoing, in jurisdictions where we must refund the
greater of: 1) aggregate Premium Payments or 2) Contract Value (plus any amount
deducted for state premium taxes) in the event you exercise the free look right,
any portion of the initial Net Premium Payment to be allocated to the Variable
Account will be allocated to the Market Street Money Market Subaccount during
the free look period. At the end of that period, the amount in the Market Street
Money Market Subaccount will be allocated to the Subaccounts as designated by
you in proportion to the allocation percentage for each Subaccount set forth in
the Net Premium Payment allocation schedule then in effect. We assume the free
look period ends 20 days after the date the Contract is issued.

      We allocate subsequent Net Premium Payments as of the Valuation Date we
receive Net Premium Payments, based on your allocation percentages then in
effect. At the time of allocation, we apply Net Premium Payments to the purchase
of Fund shares. The net asset value of the shares purchased are converted into
Accumulation units.

      We reserve the right to limit the number of Variable Account Subaccounts
other than the Market Street Money Market Subaccount used in a single Contract
over the entire life of the Contract to 16.
                                                                               
      The Subaccount values will vary with their investment experience, and 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 Contract Value among the Subaccounts of the Variable
Account and between the Variable Account and the Fixed Account (subject to the
limitations set forth below) by making a written transfer request. If you elect
the telephone transaction privilege, you may make transfers by telephone. See
"Telephone Transaction Privilege", page . Transfers are made as of the Valuation
Day that the request for transfer is received at the Home Office. Transfers to
or from the Subaccounts may be postponed under certain circumstances. See
"Payments," page .

      We currently allow transfers to the Fixed Account of all or any part of
the Variable Account Contract Value, without charge or penalty. We reserve the
right to restrict transfers to the Fixed Account to 25% of the Variable Account
Contract Value during any Contract Year.

      You may, (only one each year and within 45 days after the end of the
calendar year) transfer a portion of the value in the Fixed Account to the
Variable Account. Prior to the end of the calendar year, we determine the
maximum percentage that may be transferred from the Fixed Account. This
percentage will be at least 10% of the Contract Value in the Fixed Account. 
After a transfer from the Fixed Account to the Variable Account, we reserve the
right to require that the value transferred remain in the Variable Account for
at least one year before it may be transferred back to the Fixed Account.

      We do not permit transfers between the Variable Account and the Fixed
Account after the Annuitization Date.

      We have no current intention to impose a transfer charge in the
foreseeable future. However, we reserve the right, upon prior notice, to impose
a transfer charge of $25 for each transfer in excess of twelve transfers in any
one Contract Year. See "Transfer Charge", page .

VALUE OF A VARIABLE ACCOUNT ACCUMULATION UNIT

      We set the value of a Variable Account Accumulation Unit for each
Subaccount at $10 when the Subaccounts commenced operations. We determine the
value for any subsequent Valuation Period by multiplying the Accumulation Unit
value for each Subaccount for the immediately preceding Valuation Period by the
Net Investment Factor for the Subaccount during the subsequent Valuation Period.
The value of an Accumulation Unit may increase or decrease from Valuation Period
to Valuation Period. No minimum Accumulation Unit value is guaranteed. The
number of Accumulation Units will not change as a result of investment
experience.

      Net Investment Factor.  Each Subaccount of the Variable Account has its 
own Net Investment Factor.

      -  The Net Investment Factor measures the daily investment performance of
         that Subaccount.

      -  The Net Investment Factor may be greater or less than one; therefore,
         the value of an Accumulation Unit may increase or decrease.

      -  Changes in the Net Investment Factor may not be directly proportional
         to changes in the net asset value of Fund shares, because of the
         deduction for the Mortality and Expense Risk Charge and Administration
         Charge.

      Fund shares are valued at their net asset value. The Net Investment Factor
allows for the monthly reinvestment of daily dividends that are credited by some
Funds (the Market Street Money Market Portfolio).

  DETERMINING THE CONTRACT VALUE

      The Contract Value is the sum of:

      1) the value of all Variable Account Accumulation Units, and

      2) amounts allocated and credited to the Fixed Account.

      When charges or deductions are made against the Contract Value, we deduct
an appropriate number of Accumulation Units from the Variable Account and an
appropriate amount from the Fixed Account in the same proportion that the your
interest in the Variable Account and Fixed Account bears to the total Contract
Value. Value held in the Fixed Account is not subject to Variable Account
charges (Mortality and Expense Risk and Administration Charges), but may be
subject to Contingent Deferred Sales Charges, the Annual Contract Fee, optional
Enhanced Death Benefit Rider charge, and premium taxes, if applicable.

ANNUITIZATION

      Maturity Date. You select the Maturity Date on the application. Such date
must be at least 2 years after the Date of Issue, unless otherwise approved (10
years after the Date of Issue in the State of Oregon). If no specific Maturity
Date is selected, the Maturity Date will be the date you reach age 90 (the
Annuitant's age 90 if the Owner is not a natural person); or, if later, 10 years
after the Date of Issue.

      If you request in writing (see "Ownership Provisions", page ), and we
approve the request, the Maturity Date may be accelerated or deferred.

      Election of Payment Options. You may, with prior written notice and, at
any time prior to the Annuitization Date, elect one of the Annuity Payment
Options. We apply the Contract Value in each Subaccount (less any premium tax
previously unpaid) to provide a Variable Annuity payment. We apply and the
Contract Value in the Fixed Account (less any premium tax previously unpaid) to
provide a Fixed Annuity payment.




                                       24
    

<PAGE>   31

   

      If an election of an Annuity Payment Option is not on file with National
Life on the Annuitization Date, we will pay the proceeds as Option 3 - Payments
for Life with 120 months certain. You may elect, revoke or change an Annuity
Payment Option at any time before the Annuitization Date within 30 days prior
written notice. The Annuity Payment Options available are described below.

      Frequency and Amount of Annuity Payments. We pay annuity payments as
monthly installments, unless you select annual, semi-annual or quarterly
installments. If the amount to be applied under any Annuity Payment Option is
less than $3,500, we have the right to pay such amount in one lump sum in lieu
of the payments otherwise selected. In addition, if the payments selected would
be or become less than $100, we have the right to change the frequency of
payments that will result in payments of at least $100. In no event will we make
payments under an annuity option less frequently than annually.

ANNUITIZATION - VARIABLE ACCOUNT

      We will determine the dollar amount of the first Variable Annuity payment
by dividing the Variable Account Contract Value on the Annuitization Date by
1,000 and applying the result as set forth in the applicable Annuity Table. The
amount of each Variable Annuity payment depends on the age of the Chosen Human 
Being at the time the first payment is due, and the sex of the Chosen Human
Being, if applicable, unless otherwise required by law.

      -    Variable Annuity payments vary in amount in accordance with the
           investment performance of the Variable Account;

      -    To establish the number of Annuity Units representing each monthly
           annuity payment, the dollar amount of the first annuity payment as 
           determined above is divided by the value of an Annuity Unit on the 
           Annuitization Date;

      -    The number of Annuity Units remains fixed during the annuity payment
           period;

      -    The dollar amount of the second and subsequent payments is not
           predetermined and may change from month to month; and

      -    The dollar amount of each subsequent payment is determined by
           multiplying the fixed number of Annuity Units by the value of an
           Annuity Unit for the Valuation Period in which the payment is due.

      We guarantee that the dollar amount of each payment after the first will
 not be affected by variations in mortality experience from mortality
 assumptions used to determine the first payment.

      Value of an Annuity Unit. The value of an Annuity Unit for a Subaccount is
set at $10 when the first Fund shares are purchased. The value of an Annuity
Unit for a Subaccount for any subsequent Valuation Period is determined by
multiplying the value of an Annuity Unit for the immediately preceding Valuation
Period by the applicable Net Investment Factor for the Valuation Period for
which the value of an Annuity Unit is being calculated and multiplying the
result by an interest factor to neutralize the assumed investment rate of 3.5%
per annum (see "Net Investment Factor", page ).

      Assumed Investment Rate. A 3.5% Assumed Investment Rate is built into the
Annuity Tables contained in the Contracts. A higher assumption would mean a
higher initial payment but more slowly rising or more rapidly falling subsequent
payments. A lower assumption would have the opposite effect. If the actual
investment return is at the annual rate of 3.5%, the annuity payments will be
level.

ANNUITIZATION - FIXED ACCOUNT

      A Fixed Annuity is an annuity with payments which are guaranteed as to
dollar amount during the annuity payment period. We determine the amount of the
periodic Fixed Annuity payments by 



                                       25
    

<PAGE>   32

   

applying the Fixed Account Contract Value to the applicable Annuity Table in
accordance with the Annuity Payment Option elected. This is done at the
Annuitization Date on an age nearest birthday basis.

      We do not credit discretionary interest to Fixed Annuity payments during
the annuity payment period for annuity options based on life contingencies. The
Annuitant must rely on the Annuity Tables applicable to the Contracts to
determine the amount of Fixed Annuity payments.

ANNUITY PAYMENT OPTIONS

      Any of the following Annuity Payment Options may be elected:

      Option 1-Payments for a Stated Time. We will make monthly payments for the
      number of years selected, which may range from 5 years to 30 years.

      Option 2-Payments for Life-An annuity payable monthly during the lifetime
      of an Chosen Human Being (who may be named at the time of election of the
      Payment Option), ceasing with the last payment due prior to the death of
      the Chosen Human Being. It would be possible under this option for the
      payee to receive only one annuity payment if the annuitant dies before
      the second annuity payment date, two annuity payments if the Annuitant
      dies before the third annuity payment date, and so on.

      Option 3-Payments for Life with Period Certain-Guaranteed - An annuity
      that if at the death of the Chosen Human Being payments have been made
      for less than 10 or 20 years, as selected, we guarantee to continue
      annuity payments during the remainder of the selected period to the Payee
      or another recipient as chosen by the Payee at the time the Annuity
      Payment Option is selected.

      In the alternative, the Payee may, at any time, elect to have the present
value of the guaranteed number of annuity payments remaining paid in a lump sum,
computed as of the date on which we receive notice of death of the Chosen Human
Being is received by us at our Home Office.

      We may allow other Annuity Payment Options.

      Some of the stated Annuity Payment Options may not be available in all
states. You may request an alternative non-guaranteed option by giving notice in
writing prior to Annuitization. If a request is approved by us, it will be
permitted under the Contract.

      IRA's and Tax-Sheltered Annuities are subject to the minimum Distribution
requirements set forth in the Code.

      Under Payment Option 1, you may change to any other Payment Option at any
time. At the time of the change, remaining value will be applied to the new
Payment Option to determine the amount of the new payments. Under Payment Option
1, you may also fully surrender the Contract at any time or make Withdrawals at
any time or from time to time. A surrender or Withdrawal is subject to any
applicable Contingent Deferred Sales Charge at the time of the surrender or
Withdrawal.

DEATH OF OWNER

      If you or a Joint Owner dies prior to the Annuitization Date, then, we
will pay (unless the Enhanced Death Benefit Rider has been elected) a Death
Benefit to the Beneficiary.

      If you or a Joint Owner dies prior to attaining age 81, the Death Benefit
will be equal to the greater of: 

      (a) the Contract Value, or

      (b) the Net Premium Payments made to the Contract, 

      in each case minus all Withdrawals (including any CDSC deducted in
connection with such Withdrawals), and, minus any applicable premium tax charge
to be assessed upon distribution.

      If you or a Joint Owner dies after attaining age 81, then the Death
Benefit shall be equal to the Contract Value, minus any applicable premium tax
charge.



                                       26
    

<PAGE>   33

   

      Unless the Beneficiary is the deceased Owner's (or Joint Owner's) spouse,
the Death Benefit must be distributed within five years of such Owner's death.
The Beneficiary may, elect to receive Distribution in the form of a life annuity
or an annuity for a period not exceeding his or her life expectancy. Such
annuity must begin within one year following the date of the Owner's death and
is currently available only as a Fixed Annuity. If the Beneficiary is the spouse
of the deceased Owner (or Joint Owner), then the Contract may be continued
without any required Distribution. If the deceased Owner (or Joint Owner) and
the Annuitant are the same person, the death of that person will be treated as
the death of the Owner for purposes of determining the Death Benefit payable.

      Qualified Contracts may be subject to specific rules set forth in the
Plan, Contract, or Code concerning Distributions upon the death of the Owner.

DEATH OF ANNUITANT PRIOR TO THE ANNUITIZATION DATE

      If an Annuitant who is not an Owner dies prior to the Annuitization Date,
the Contract will mature, and a Death Benefit equal to the Cash Surrender Value
of the Contract will be payable to the Beneficiary. If the Owner is a natural
person and a contingent Annuitant has been named or the Owner names a contingent
Annuitant within 90 days of the Annuitant's death, the Contract may be continued
without any required Distribution. If no Beneficiary is named (or if the
Beneficiary predeceases the Annuitant), then the Death Benefit will be paid to
the Owner. If the Owner is not a natural person, then the death of the Annuitant
will be treated as if it were the death of the Owner, and the disposition of the
Contract will follow the death of the Owner provisions set forth above.

      In any case where a Death Benefit is paid, the value of the Death Benefit
will be determined as of the Valuation Day coinciding with or next following the
date we receive in writing:

      (1) due proof of the Annuitant's or an Owner's (or Joint Owner's) death;

      (2) an election for either a single sum payment or an Annuity Payment
          Option (currently only Fixed Annuities are available in these
          circumstances); and

      (3) any form required by state insurance laws.

      If a single sum payment is requested, we will make payment in accordance
with any applicable laws and regulations governing the payment of Death
Benefits. If an Annuity Payment Option is requested, the Beneficiary must make
an election during the 90-day period commencing with the date we receive 
written notice and as otherwise required by law. If no election has been made
by the end of such 90-day period commencing with the date we receive written
notice or as otherwise required by law the Death Benefit will be paid in a
single sum payment.

                                       27
    

<PAGE>   34

   

GENERATION-SKIPPING TRANSFERS

      We may determine whether the Death Benefit or any other payment
constitutes a direct skip as defined in Section 2612 of the Code, and the amount
of the tax on the generation-skipping transfer resulting from such direct skip.
If applicable, the payment will be reduced by any tax National Life is required
to pay by Section 2603 of the Code.

      A direct skip may occur when property is transferred to or a Death Benefit
is paid to an individual two or more generations younger than the Owner.

OWNERSHIP PROVISIONS

      Unless otherwise provided, the Owner has all rights under the Contract. If
the purchaser names someone other than himself or herself as owner, the
purchaser will have no rights under the contract. If Joint Owners are named,
each Joint Owner possesses an undivided interest in the Contract. The death of
any Joint Owner triggers the provisions of the Contract relating to the death of
the Owner. Unless otherwise provided, when Joint Owners are named, the exercise
of any ownership right in the Contract (including the right to surrender the
Contract or make a Withdrawal, to change the Owner, the Annuitant, a Contingent
Annuitant, the Beneficiary, the Annuity Payment Option or the Maturity Date)
requires a written indication of an intent to exercise that right, signed by all
Joint Owners.




                                       29
    

<PAGE>   35

   

      Prior to the Annuitization Date, the Owner may name a new Owner. Such
change may be subject to state and federal gift taxes, and may also result in
current federal income taxation (see "Federal Income Tax Considerations", page
"). Any change of Owner will automatically revoke any prior Owner designation.
Any request for change of Owner must be (1) made by proper written application,
(2) received and recorded by National Life at its Home Office, and (3) may
include a signature guarantee as specified in the "Surrender and Withdrawal"
provision on page . The change is effective on the date the written request is
signed. A new choice of Owner will not apply to any payment made or action we
take prior to the time it was received and recorded.

      The Owner may request a change in the Annuitant or contingent Annuitant
before the Annuitization Date. Such a request must be made in writing on a form
acceptable to us and must be signed by the Owner, and the person to be named as
Annuitant or contingent Annuitant. Any such change is subject to underwriting
and approval by us.

                              CHARGES AND DEDUCTIONS

      All of the charges described in this section apply to Variable Account
allocations. Allocations to the Fixed Account are subject to Contingent Deferred
Sales Charges, the Annual Contract Fee and Premium Tax deductions and the charge
for the Enhanced Death Benefit Rider, if applicable. The Fixed Account is not
subject to the Mortality and Expense Risk Charge and the Administration Charge.
We may realize a profit from any of these charges. Any such profit may be used
for any purpose, including payment of distribution expenses.

      We deduct the charges described below to cover our costs and expenses,
services provided and risks assumed under the Contracts. We incur certain costs
and expenses for the distribution and administration of the Contracts and for
providing the benefits payable thereunder. More particularly, the administrative
services include:

    - processing applications for and issuing the Contracts;

    - processing purchases and redemptions of Fund shares as required (including
      automatic withdrawal services);

    - maintaining records;

    - administering annuity payouts;

    - furnishing accounting and valuation services (including the calculation
      and monitoring of daily Subaccount values);

    - reconciling and depositing cash receipts;

    - providing Contract confirmations;

    - providing toll-free inquiry services; and

    - furnishing telephone transaction privileges.

    The risks we assume include:

    (1) the risk that the actual life-span of persons receiving annuity payments
        under Contract guarantees will exceed the assumptions reflected in our
        guaranteed rates (these rates are incorporated in the Contract and 
        cannot be changed);

    (2) the risk that Death Benefits, or the Enhanced Death Benefit under the
        optional Enhanced Death Benefit Rider, will exceed the actual Contract
        Value;



                                       30
    

<PAGE>   36

   

    (3) the risk that more Owners than expected will qualify for waivers of the
        Contingent Deferred Sales Charge; and

    (4) the risk that our costs in providing the services will exceed our
        revenues from the Contract charges (which we cannot change).

      The amount of a charge will not necessarily correspond to the costs
associated with providing the services or benefits indicated by the designation
of the charge. For example, the Contingent Deferred Sales Charge collected may
not fully cover all of the distribution expenses we incur.

DEDUCTIONS FROM THE VARIABLE ACCOUNT

    We deduct from the Variable Account an amount, computed daily, which is
equal to an annual rate of 1.40% of the daily net asset value. The charge
consists of a 0.15% Administration Charge and a 1.25% Mortality and Expense Risk
Charge.

CONTINGENT DEFERRED SALES CHARGE

      We make no deduction for a sales charge from the Premium Payments for
these Contracts. However, if a Withdrawal is made or a Contract is surrendered,
we will with certain exceptions, deduct a Contingent Deferred Sales Charge
("CDSC") not to exceed 7% of the lesser of the total of all Net Premium Payments
made within 84 months prior to the date of the request to surrender or the
amount withdrawn.

      The CDSC is calculated by multiplying the applicable CDSC percentages
noted below by the Net Premium Payments that are withdrawn or surrendered. For
purposes of calculating the CDSC Withdrawals or surrenders are considered to
come first from the oldest Net Premium Payment made to the Contract, then the
next oldest Net Premium Payment and so forth. No CDSC is ever assessed with
respect to a Withdrawal or surrender of earnings on Net Premium Payments. For
tax purposes, a surrender is usually treated as a withdrawal of earnings first.
This charge will apply in the amounts set forth below to Net Premium Payments
within the time periods set forth.

      The CDSC applies to Net Premium Payments as follows:

<TABLE>
<CAPTION>
NUMBER OF COMPLETED   CONTINGENT DEFERRED  NUMBER OF COMPLETED   CONTINGENT DEFERRED

      0                    7%                    4                   3%
      1                    6%                    5                   2%
      2                    5%                    6                   1%
      3                    4%                    7                   0%
</TABLE>

      In any Contract Year after the first Contract Year (except in the states
referred to in the last sentence of this paragraph) you may make Withdrawals
without a CDSC of an aggregate amount equal to 15% of the Contract Value as of
the most recent Contract Anniversary. This CDSC-free Withdrawal privilege does
not apply to full surrenders of the Contract, and if a full surrender is made
within one year of exercising a CDSC-free Withdrawal, then the CDSC which would
have been assessed at the time of the Withdrawal will be assessed at the time of
surrender. The CDSC-free feature is also non-cumulative. This means that free
amounts not taken during any given Contract Year cannot be taken as free amounts
in a subsequent Contract Year. In addition, any amount withdrawn in order to
meet minimum Distribution requirements under the Code shall be free of CDSC. In
the first Contract Year a CDSC-free Withdrawal is available only by setting up a
monthly systematic Withdrawal program for an amount not exceeding the annual
CDSC-free Withdrawal amount (see "Available Automated Fund Management
Features-Systematic Withdrawals", page ). You may be subject to a tax penalty if
you take Withdrawals prior to age 59 1/2 (see "Federal Income Tax
Considerations", page ). In any states which require that any CDSC-free
Withdrawal provision be available on full surrenders as well as 




                                       31
    

<PAGE>   37

   

Withdrawals, the CDSC-free Withdrawal provision will apply to full surrenders
but will be limited to 10% of the Contract Value as of the most recent Contract
Anniversary for both Withdrawals and full surrenders.

      In addition, no CDSC will be deducted:

      (1) upon the Annuitization of Contracts,

      (2) upon payment of a death benefit pursuant to the death of the Owner, or

      (3) from any values which have been held under a Contract for at least 84
          months.

      No CDSC applies upon the transfer of value among the Subaccounts or
between the Fixed Account and the Variable Account.

      When a Contract is held by a charitable remainder trust, the amount which
may be withdrawn from this Contract without application of a CDSC after the
first Contract Year, shall be the larger of (a) or (b), where (a) is the amount
which would otherwise be available for Withdrawal without application of a CDSC;
and where (b) is the difference between the Contract Value as of the last
Contract Anniversary and the Net Premium Payments made to the Contract, less all
Withdrawals as of the last Contract Anniversary.

      We will waive the CDSC if the Owner dies or if the Owner annuitizes.
However, the Owner may not elect a settlement option under which he or she has
the right to receive a lump sum prior to seven years after the date of the last
Premium Payment, unless a CDSC is paid at the time of payment of the lump sum.

      We will also waive the CDSC if, following the first Contract Anniversary,
you are confined to an eligible nursing home for at least the 90 consecutive
days ending on the date of the Withdrawal request.

ANNUAL CONTRACT FEE

    For Contracts with a Contract Value of less than $50,000 as of the Date of
Issue or any subsequent Contract Anniversary prior to the Annuitization Date, we
will assess an Annual Contract Fee of $30.00. This fee will be assessed annually
in advance on the Date of Issue and thereafter on each Contract Anniversary on
which the Contract Value is less than $50,000. No Annual Contract Fee will be
assessed after the Annuitization Date. This fee will be taken pro rata from all
Subaccounts of the Variable Account and the Fixed Account.

TRANSFER CHARGE

    Currently, unlimited free transfers are permitted among the Subaccounts, and
transfers between the Fixed Account and the Variable Account are permitted free
of charge within the limits described on page . We have no present intention to
impose a transfer charge in the foreseeable future. However, we reserve the
right to impose in the future a transfer charge of $25 on each transfer in
excess of twelve transfers in any Contract Year.

    If imposed, we will deduct the transfer charge from the amount being
transferred. All transfers requested on the same Valuation Day are treated as
one transfer transaction. Any future transfer charge will not apply to transfers
made pursuant to the Dollar Cost Averaging and Portfolio Rebalancing features or
if there has been a material change in the investment policy of the Fund from
which the transfer is being made. These transfers will not count against the
twelve free transfers in any Contract Year.

PREMIUM TAXES

      If a governmental entity imposes premium taxes, we make a deduction for
premium taxes in a corresponding amount. Certain states impose a premium tax,
currently ranging up to 3.5%. We will pay premium taxes at the time imposed
under applicable law. Where we are required to pay this premium tax, we may
deduct an amount equal to premium taxes from the Premium Payment. We currently
intend to make this deduction from Premium Payments only in South Dakota. In the
remaining states which assess premium taxes, we currently expect to make
deductions for premium taxes at the time of Annuitization, death of the Owner,
or surrender, although we also reserve the right to make such a deduction at the
time we pay premium taxes to the applicable taxing authority.

CHARGE FOR OPTIONAL ENHANCED DEATH BENEFIT RIDER

      Annual charges are made if you elect the optional Enhanced Death Benefit 
Rider. See "Optional Enhanced Death Benefit Rider," page . The annual charge for
the Enhanced Death Benefit Rider is 0.20% of Contract Value as of the date the
charge is deducted. The annual charge will be deducted at issue (or at the time
of election, if elected after issue), and then on each Contract Anniversary
thereafter, up to and including age 80 on an age-nearest-birthday basis as of
the relevant Contract Anniversary. After age 80, we will discontinue the charge.
We will make the charge pro rata from the Subaccounts of the Variable Account
and the Fixed Account.

OTHER CHARGES

      The Variable 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. Information on the fees and expenses for
the Funds is set forth in "Underlying Fund Annual Expenses" on page .

      More detailed information is contained in the Funds' prospectuses which
accompany this prospectus.

                         CONTRACT RIGHTS AND PRIVILEGES

FREE LOOK

      You may revoke the Contract at any time between the Date of Issue and the
date 10 days after receipt of the Contract and receive a refund of the Contract
Value plus any charges assessed at issue, including the Annual Contract Fee,
charge for the optional Enhanced Death Benefit Rider, and any premium tax,
unless otherwise required by state and/or federal law. Some states may require a
longer free look period. Where the Contract Value is refunded, you will have
borne the investment risk and been entitled to the benefit of the investment
performance of the chosen Subaccounts during the time the Contract was in force.

      In the case of IRA's and states that require the return of Premium
Payments, we will refund the greater of: (i) Premium Payments or (ii) Contract
Value plus any amount we have deducted for state premium taxes. In such cases,
we may require that all Contract Value allocated to the Variable Account
initially be held in the Market Street Money Market Subaccount. At the end of
the free look period, we will allocate Contract Value among the Subaccounts
based on the allocation percentages specified in the application. For this
purpose, we assume the free look period ends 20 days after the date the
Contract is issued.

      In order to revoke the Contract, it must be mailed or delivered to our
Home Office. Mailing or delivery must occur on or before 10 days after receipt
of the Contract for revocation to be effective, except where we require the
allocation of Contract Value to the Market Street Money Market Subaccount for
the free look period. In order to revoke the Contract, if it has not been
received, written notice must be mailed or delivered to the Home Office.




                                       33
    

<PAGE>   39

   

      The liability of the Variable Account under this provision is limited to
the Contract Value in each Subaccount on the date of revocation. Any additional
amounts refunded to you will be paid by us.

SURRENDER AND WITHDRAWAL

      At any time prior to the Annuitization Date (or thereafter if Payment
Option 1 has been elected) you may, upon proper written application deemed by us
to be in good order, surrender the Contract Value. "Proper written application"
means that you must request the surrender in writing and include the Contract.
We may require that the signature(s) be guaranteed by a member firm of a major
stock exchange or other depository institution qualified to give such a
guaranty.

      We will, upon receipt of any such written request, pay to you the Cash
Surrender Value. The Cash Surrender Value will reflect any applicable CDSC (see
"Contingent Deferred Sales Charge", page ) and, in certain states, a premium tax
charge (see "Premium Taxes", page ). The Cash Surrender Value may be more or
less than the total of Premium Payments you made depending on the market value
of the underlying Fund shares, the amount of any applicable CDSC, and other
factors.                                   

      We will normally not permit Withdrawal or Surrender of Premium Payments
made by check within the 15 calendar days prior to the date the request for
Withdrawal or Surrender is received.

      At any time before the death of the Owner and after 30 days from the Date
of Issue, the Owner may make a Withdrawal of a portion of the Contract Value.
The minimum Withdrawal is $500. At least $3500 in Contract Value must remain
after any Withdrawal.

      Generally, Withdrawals in the first Contract Year and Withdrawals in
excess of 15% (10% in certain states) of Contract Value as of the most recent
Contract Anniversary in any Contract Year are subject to the CDSC. See
"Contingent Deferred Sales Charge", page . However, see "Available Automated
Fund Management Features-Systematic Withdrawals" page , for information on a
limited means of making systematic Withdrawals in the first year free of the
CDSC. Withdrawals will be deemed to be taken from Net Premium Payments in
chronological order, with the oldest Net Premium Payment being withdrawn first.
This method will tend to minimize the amount of the CDSD.

      The Withdrawal will be taken from the Subaccounts based on your
instructions at the time of the Withdrawal. During the first Contract Year, we
may require that Withdrawals be taken pro rata from the Subaccounts and the
Fixed Account. If you provide specific instructions, amounts must be deducted
first from the Variable Account and may only be deducted from the Fixed Account
to the extent that the Contract Value in the Variable Account is insufficient to
accomplish the Withdrawal. If specific allocation instructions are not provided,
the Withdrawal will be deducted pro rata from the Subaccounts and from the Fixed
Account. Any CDSC associated with a Withdrawal will be deducted from the
Subaccounts and from the Fixed Account based on the allocation percentages of
the Withdrawal. Any amount of CDSFC that we deduct from a Subaccount which is in
excess of the available value in that Subaccount will be deducted pro rata among
the remaining Subaccounts and the Fixed Account. If the Withdrawal cannot be
processed in accordance with your instructions, then we will not process it 
until we receive further instructions.

    A Surrender or a Withdrawal may have tax consequences. See "Federal Income
Tax Considerations", page .

PAYMENTS

      We will pay any funds surrendered or withdrawn from the Variable Account
within 7 days of receipt of such request. However, we reserve the right to
suspend or postpone the date of any payment or transfer of any benefit or values
for any Valuation Period:

      (1) when the New York Stock Exchange ("Exchange") is closed,



                                       34
    

<PAGE>   40
   


      (2) when trading on the Exchange is restricted,

      (3) when an emergency exists as a result of which disposal of securities
          held in the Variable Account is not reasonably practicable or it is 
          not reasonably practicable to determine the value of the Variable 
          Account's net assets, or

      (4) during any other period when the Securities and Exchange Commission,
          by order, so permits for the protection of security holders, provided
          that applicable rules and regulations of the Securities and Exchange
          Commission shall govern as to whether the conditions prescribed in (2)
          and (3) exist.

The rules and regulations of the Securities and Exchange Commission shall
govern as to whether the conditions prescribed in (2) and (3) exist.

      We reserve the right to delay payment of any amounts allocated to the
Fixed Account which are payable as a result of a Surrender or Withdrawal for up
to six months after we receive a written request in a form satisfactory to us.

SURRENDERS AND WITHDRAWALS UNDER A TAX-SHELTERED ANNUITY CONTRACT

      Where the Contract has been issued as a Tax-Sheltered Annuity, the Owner
may surrender or make a Withdrawal of part or all of the Contract Value at any
time this Contract is in force prior to the earlier of the Annuitization Date or
the death of the Designated Annuitant except as provided below:

      (a)   The surrender or Withdrawal of Contract Value attributable to
            contributions made pursuant to a salary reduction agreement (within
            the meaning of Code Section 402(g)(3)(A) or (C)), or transfers from
            a Custodial Account described in Section 403(b)(7) of the Code, may
            be executed only:

            1.    when the Owner attains age 59 1/2, separates from service,
                  dies, or becomes disabled (within the meaning of Code Section
                  72(m)(7)); or

            2.    in the case of hardship (as defined for purposes of Code
                  Section 401 (k)), provided that any surrender of Contract
                  Value in the case of hardship may not include any income
                  attributable to salary reduction contributions.

      (b)   The surrender and Withdrawal limitations described in (a) above for
            Tax-Sheltered Annuities apply to:

            1.    salary reduction contributions to Tax-Sheltered Annuities made
                  for plan years beginning after December 31, 1988;

            2.    earnings credited to such contracts after the last plan year
                  beginning before January 1, 1989, on amounts attributable to
                  salary reduction contributions; and

            3.    all amounts transferred from 403(b)(7) Custodial Accounts
                  (except that earnings, and employer contributions as of
                  December 31, 1988 in such Custodial Accounts may be withdrawn
                  in the case of hardship).

      (c)   Any Distribution other than the above, including exercise of a
            contractual ten-day free look provision (when available) may result
            in the immediate application of taxes and penalties and/or
            retroactive disqualification of a Qualified Contract or
            Tax-Sheltered Annuity.

      A premature Distribution may not be eligible for rollover treatment. To
assist in preventing disqualification in the event of a ten-day free look,
National Life will agree to transfer the proceeds to another contract which
meets the requirements of Section 403(b) of the Code, upon proper direction by
the Owner. The foregoing is National Life's understanding of the withdrawal
restrictions which are currently applicable under Section 403(b)(11) and Revenue
Ruling 90-24. Such restrictions are




                                       35
    

<PAGE>   41
   



subject to legislative change and/or reinterpretation from time to time.
Distributions pursuant to Qualified Domestic Relations Orders will not be
considered to be a violation of the restrictions stated in this provision.

      The Contract surrender and Withdrawal provisions may also be modified
pursuant to the plan terms and Code tax provisions for Qualified Contracts.

TELEPHONE TRANSACTION PRIVILEGE

    If you elect the telephone transaction privilege, you may make changes in
Net Premium Payment allocations, transfers, or initiate dollar costs averaging
or portfolio rebalancing, by providing instructions to us at our Home Office 
over the telephone. You can make the election either on the application for the
Contract or by providing a proper written authorization to us. We reserve the
right to suspend telephone transaction privileges at any time and for any
reason. You may, on the application or by a written authorization, authorize
your National Life agent to provide telephone instructions on your behalf.

    We employ reasonable procedures to confirm that instructions communicated 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 those reasonable procedures are not followed. The procedures
followed for telephone transfers will include one or more of the following:

    (1) requiring some form of personal identification prior to acting on
        instructions received by telephone,

    (2) providing written confirmation of the transaction, and

    (3) making a tape recording of the instructions given by telephone.

AVAILABLE AUTOMATED FUND MANAGEMENT FEATURES

    We currently offer the following free automated fund management features.
However, we are not legally obligated to continue to offer these features and we
may cease offering one or more of such features at any time, after providing 60
days prior written notice to all Owners who are currently utilizing the features
being discontinued. Only one automated fund management feature is available
under any single Contract at one time.

    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 it at issue by marking the appropriate box on the initial
application and completing the appropriate instruction or after issue by filling
out similar information on a change request form and sending it to us.

    If you elect this feature, each month on the Monthly Contract Date 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. This
procedure starts with the Monthly Contract Date next succeeding the Date of
Issue or next succeeding the date of an election subsequent to purchase and
stops when 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 us.

    This feature allows you to move funds into the various investment classes on
a more gradual and systematic basis than the frequency on which Premium Payments
ordinarily are made. 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. Over time, this
will result, in a lower cost per unit than the average of the unit costs on the
days on which the automated purchases are made. This technique will not assure a
profit or protect against a loss in declining markets. 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.




                                       36

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

    In Contracts utilizing Portfolio Rebalancing from the Date of Issue, an
automatic transfer takes place which causes the percentages of the current
values in each Subaccount to match the current premium allocation percentages.
This procedure starts with the Monthly Contract Date three, six or twelve months
after the Date of Issue and continues on each Monthly Contract Date three, six
or twelve months thereafter. Contracts electing Portfolio Rebalancing after
issue will have the first automated transfer occur as of the Monthly Contract
Date on or next following the date that the election is received. Subsequent
rebalancing transfers occur every three, six or twelve months thereafter. You
may discontinue Portfolio Rebalancing at any time by submitting an appropriate
change request form.

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

    Portfolio Rebalancing results in periodic transfers out of Subaccounts that
have had relatively favorable investment performance and into Subaccounts which
have had relatively unfavorable investment performance.

      Systematic Withdrawals. At any time after one year from the Date of Issue,
if the Contract Value at the time of initiation of the program is at least
$15,000, you may elect in writing to take systematic Withdrawals of a specified
dollar amount (of at least $100) on a monthly, quarterly, semi-annual or annual
basis. You may provide specific instructions as to how the systematic
Withdrawals are to be taken, but the Withdrawals must be taken first from the
Subaccounts and may only be taken from the Fixed Account to the extent that the
Contract Value in the Variable Account is insufficient to accomplish the
Withdrawal. If you have not provided specific instructions or if specific
instructions cannot be carried out, we process the Withdrawals by taking
Accumulation Units from all of the Subaccounts in which you have an interest
and the Fixed Account on a pro rata basis. Each systematic Withdrawal is
subject to federal income taxes. In addition, a 10% federal penalty tax may be
assessed on systematic Withdrawals if you are under age 59 1/2. If you direct,
we will withhold federal income taxes from each systematic Withdrawal. A
systematic Withdrawal program terminates automatically when a systematic
Withdrawal would cause the remaining Contract Value to be $3,500 or less. If
this happens, then the systematic Withdrawal transaction causing the Contract
value to fall below $3500 will not be processed. You may discontinue systematic
Withdrawals at any time by notifying us in writing.

      A CDSC may apply to systematic Withdrawals in accordance with the
considerations set forth in "Contingent Deferred Sales Charge", page . If you
withdraw amounts pursuant to a systematic Withdrawal program, then, in most
states, you may withdraw in each Contract Year after the first Contract Year
without a CDSC an amount up to 15% of the Contract Value as of the most recent
Contract Anniversary (a different CDSC-free Withdrawal provision may apply in
certain states - see "Contingent Deferred Sales Charge," page ). Both
Withdrawals you request and Withdrawals pursuant to a systematic Withdrawal
program will count toward the limit of the amount that may be withdrawn in any
Contract Year free of the CDSC. In addition, any amount withdrawn in order to
meet minimum Distribution requirements under the Code shall be free of CDSC.

      Limited systematic Withdrawals are also available in the first Contract
Year (but after 30 days from issue). These systematic Withdrawals are limited to
monthly systematic Withdrawal programs only. The maximum aggregate amount for
the remaining months of the first Contract Year is the annual amount that may be
withdrawn in Contract Years after the first Contract Year free of a CDSC (i.e.,
either 15% or 10% of the Contract Value, depending on the state). These
systematic Withdrawals will not be subject to a CDSC. The other rules for
systematic Withdrawals made after the first Contract Year, including the $15,000
minimum Contract Value, minimum $100 payment, and allocation rules, will apply
to these systematic Withdrawals.

CONTRACT RIGHTS UNDER CERTAIN PLANS

    Contracts may be purchased in connection with a plan sponsored by an
employer. In such cases, all rights under the Contract rest with the Owner,
which may be the employer or other obligor under the plan, and benefits
available to participants under the plan are governed solely by the provisions
of the plan. Accordingly, some of the options and elections under the Contract
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 FIXED ACCOUNT

      Net Premium Payments under the Fixed Account portion of the Contract and
transfers to the Fixed Account portion are part of our general account, which
supports insurance and annuity obligations. Because of exemptive and
exclusionary provisions, interests in the general account are not registered
under the Securities Act of 1933 ("Securities Act"), nor is the general account
registered as an investment company under the Investment Company Act.
Accordingly, neither the general account nor any interest therein are generally
subject to the provisions of the Securities Act or Investment Company Act, and
we have been advised that the staff of the Securities and Exchange Commission
has not reviewed the disclosures in this prospectus which relate to the
guaranteed interest portion. Disclosures regarding the Fixed Account portion of
the Contract and the general account, however, may be subject to certain
generally applicable provisions of the federal securities laws relating to the
accuracy and completeness of statements made in prospectuses.

      The Fixed Account is made up of all our general assets, other than those
in the Variable Account and any other segregated asset account. Fixed Account
Net Premium Payments will be allocated to the Fixed Account by election of the
Owner at the time of purchase or by a later change in allocation of Net Premium
Payments. We will invest the assets of the Fixed Account in those assets we
choose and allowed by applicable law.

MINIMUM GUARANTEED AND CURRENT INTEREST RATES

      The Contract Value held in the Fixed Account is guaranteed to accumulate
at a minimum effective annual interest rate of 3.0%. We may credit the Contract
Value in the Fixed 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, in our sole discretion, anticipate changing
the current interest rate from time to time, allocations to the Fixed Account
made at different times are likely to be credited with different current
interest rates. We declare an interest rate each month to apply to amounts
allocated or transferred to the Fixed Account in that month. The rate declared
on such amounts remains in effect for twelve months. At the end of the 12-month
period, we reserve the right to 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 Fixed Account on
that date). We determine any interest credited on the amounts in the Fixed
Account in excess of the minimum guaranteed rate of 3.0% per year in our
discretion. You assume the risk that interest credited may not exceed the
guaranteed minimum rate. Amounts allocated to the Fixed Account do not share in
the investment performance of our general account or any portion thereof.

      Amounts deducted from the Fixed Account for the charge for the optional
Enhanced Death Benefit Rider, the Annual Contract Fee or transfers to the
Variable Account are, for the purpose of crediting interest, accounted for on a
last in, first out basis. Amounts deducted from the Fixed Account for
Withdrawals are accounted for on a first in, first out basis for such purpose.

      National Life reserves the right to 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 3.0% per annum or shorten the
period for which the interest rate applies to less than 12 months.




                                       38

     For Contracts purchased in the State of Washington, no Premium Payments or
Contract Value may be allocated to the Fixed Account.

                       OPTIONAL ENHANCED DEATH BENEFIT RIDER

      You may choose to include the Enhanced Death Benefit Rider in your
Contract. The Rider is subject to the restrictions and limitations set forth in 
it. Election of this optional benefit involves an additional cost. This Rider
may not be available in all states. If you elected the Enhanced Death Benefit
Rider, then the following enhanced death benefit will be payable to the
Beneficiary if you (or the first of Joint Owners) die prior to reaching age 81
(on an age nearest birthday basis) the highest of:

      (a) Contract Value;

      (b) the total of all Net Premium Payments, less all Withdrawals, and

the largest Contract Value as of any prior Contract Anniversary after
the Enhanced Death Benefit Rider was applicable to the Contract, plus Net
Premium Payments and minus any Withdrawals (including any CDSC deducted in
connection with such Withdrawals), since such Contract Anniversary.

We calculate this as of the date we receive due proof of death. Any applicable
premium tax charge payable on your death will be applied to reduce the value of
the determined enhanced death benefit (see "Premium Taxes, page ).

      If you (or the first of Joint Owners) die at age 81 or later, the death
benefit will not be enhanced and will be an amount equal to Contract Value, less
any applicable premium tax charge.

      The Enhanced Death Benefit Rider is available at issue if you are age 75
or younger. It is available after issue if you are age 75 or younger only on a
Contract Anniversary and only if at the time of the Rider is requested the
Contract Value is greater than the total of all Net Premium Payments less all
Withdrawals. 

      The annual charge for this Rider is 0.20% of Contract Value. After you
reach ago 80, on an age nearest birthday basis, we discontinue the charge. See
"Charge for Optional Enhanced Death Benefit Rider", page .

      We distribute the Enhanced Death Benefit in the same manner as the normal
Death Benefit. See "Death of Owner", page .

                      FEDERAL INCOME TAX CONSIDERATIONS

      The following discussion is general in nature and is not intended as tax
advice. Each person concerned should consult a competent tax advisor. No attempt
is made to consider any applicable state tax or other tax laws.

      If you invest in a variable annuity as part of a pension plan or
employer-sponsored retirement program, your contract is called a Qualified
Contract. If your annuity is independent of any formal retirement or pension
plan, it is termed a Non-Qualified Contract. The tax rules applicable to
Qualified Contracts vary according to the type of retirement plan and the terms
and conditions of the plan.

TAXATION OF NON-QUALIFIED CONTRACTS

      Non-Natural Person. If a non-natural person (e.g., a corporation or a
trust) owns a Non-Qualified Contract, the taxpayer generally must include in
income any increase in the excess of the account value over the investment in
the Contract (generally, the premiums or other consideration paid for the
contract) during the taxable year. There are some exceptions to this rule and a
prospective owner that is not a natural person should discuss these with a tax
adviser.

      The following discussion generally applies to Contracts owned by natural
persons.

      Withdrawals. When a withdrawal from a Non-Qualified Contract occurs, the
amount received will be treated as ordinary income subject to tax up to an
amount equal to the excess (if any) of the account value immediately before the
distribution over the Owner's investment in the Contract (generally, the
premiums or other consideration paid for the Contract, reduced by any amount
previously distributed from the Contract that was not subject to tax) at that
time. In the case of a surrender under a Non-Qualified Contract, the amount
received generally will be taxable only to the extent it exceeds the Owner's
investment in the Contract.

      Penalty Tax on Certain Withdrawals. In the case of a distribution from a
Non-Qualified Contract, there may be imposed a federal tax penalty equal to ten
percent of the amount treated as income. In general, however, there is no
penalty on distributions:

      -     made on or after the taxpayer reaches age 59 1/2

      -     made on or after the death of an Owner;

      -     attributable to the taxpayer's becoming disabled; or

      -     made as part of a series of substantially equal periodic payments
            for the life (or life expectancy) of the taxpayer.
    

                                       40
    

<PAGE>   46
   

Other exceptions may be applicable under certain circumstances and special rules
may be applicable in connection with the exceptions enumerated above. You should
consult a tax adviser with regard to exceptions from the penalty tax.

      Annuity Payments. Although tax consequences may vary depending on the
payout option elected under an annuity contract, a portion of each annuity
payment is generally not taxed and the remainder is taxed as ordinary income.
The non-taxable portion of an annuity payment is generally determined in a
manner that is designed to allow you to recover your investment in the contract
ratably on a tax-free basis over the expected stream of annuity payments, as
determined when annuity payments start. Once your investment in the contract has
been fully recovered, however, the full amount of each annuity payment is
subject to tax as ordinary income.

      Taxation of Death Benefit Proceeds. Amounts may be distributed from a
Contract because of your death or the death of the Annuitant. Generally, such
amounts are includible in the income of the recipient as follows: (i) if
distributed in a lump sum, they are taxed in the same manner as a surrender of
the Contract, or (ii) if distributed under a payout option, they are taxed in
the same way as annuity payments.

      Transfers, Assignments or Exchanges of a Contract. A transfer or
assignment of ownership of a Contract, the designation of an annuitant, the
selection of certain maturity dates, or the exchange of a Contract may result in
certain tax consequences to you that are not discussed herein. An owner
contemplating any such transfer, assignment or exchange, should consult a tax
advisor as to the tax consequences.

      Withholding. Annuity distributions are generally subject to withholding
for the recipient's federal income tax liability. Recipients can generally
elect, however, not to have tax withheld from distributions.

      Multiple Contracts. All annuity contracts that are issued by us (or our
affiliates) to the same owner during any calendar year are treated as one
annuity contract for purposes of determining the amount includible in such
owner's income when a taxable distribution occurs.

TAXATION OF QUALIFIED CONTRACTS

      The tax rules applicable to Qualified Contracts vary according to the type
of retirement plan and the terms and conditions of the plan. Your rights under a
Qualified Contract may be subject to the terms of the retirement plan itself,
regardless of the terms of the Qualified Contract. Adverse tax consequences may
result if you do not ensure that contributions, distributions and other
transactions with respect to the Contract comply with the law.

      Individual Retirement Accounts (IRAs), as defined in Section 408 of the
Internal Revenue Code (Code), permit individuals to make annual contributions of
up to the lesser of $2,000 or 100% of adjusted gross income. The contributions
may be deductible in 


                                       41
    

<PAGE>   47

   
whole or in part, depending on the individual's income. Distributions from
certain pension plans may be "rolled over" into an IRA on a tax-deferred basis
without regard to these limits. Amounts in the IRA (other than nondeductible
contributions) are taxed when distributed from the IRA. A 10% penalty tax
generally applies to distributions made before age 59 1/2, unless certain
exceptions apply. The Internal Revenue Service has not reviewed the Contract for
qualification as an IRA, and has not addressed in a ruling of general
applicability whether a death benefit provision such as the optional Enhanced
Death Benefit provision in the Contract comports with IRA qualification
requirements.

      SIMPLE IRAs permit certain small employers to establish SIMPLE plans as
provided by Section 408(p) of the Code, under which employees may elect to defer
to a SIMPLE IRA a percentage of compensation up to $6,000 (as increased for cost
of living adjustments). The sponsoring employer is required to make matching or
non-elective contributions on behalf of employees. Distributions from SIMPLE
IRAs are subject to the same restrictions that apply to IRA distributions and
are taxed as ordinary income. Subject to certain exceptions, premature
distributions prior to age 59 1/2 are subject to a 10 percent penalty tax, which
is increased to 25 percent if the distribution occurs within the first two years
after the commencement of the employee's participation in the plan.

      Roth IRAs, as described in Code section 408A, permit certain eligible
individuals to contribute to make non-deductible contributions to a Roth IRA in
cash or as a rollover or transfer from another Roth IRA or other IRA. A rollover
from or conversion of an IRA to a Roth IRA is generally subject to tax and other
special rules apply. The Owner may wish to consult a tax adviser before
combining any converted amounts with any other Roth IRA contributions, including
any other conversion amounts from other tax years. Distributions from a Roth IRA
generally are not taxed, except that, once aggregate distributions exceed
contributions to the Roth IRA, income tax and a 10% penalty tax may apply to
distributions made (1) before age 59 1/2 (subject to certain exceptions) or (2)
during the five taxable years starting with the year in which the first
contribution is made to any Roth IRA. A 10% penalty tax may apply to amounts
attributable to a conversion from an IRA if they are distributed during the five
taxable years beginning with the year in which the conversion was made.

      Corporate pension and profit-sharing plans under Section 401(a) of the
Code allow corporate employers to establish various types of retirement plans
for employees, and self-employed individuals to establish qualified plans for
themselves and their employees. Adverse tax consequences to the retirement plan,
the participant or both may result if the Contract is transferred to any
individual as a means to provide benefit payments, unless the plan complies with
all the requirements applicable to such benefits prior to transferring the
Contract. The Contract includes an Enhanced Death Benefit that in some cases may
exceed the greater of the premium payments or the account value. The Death
Benefit could be characterized as an incidental benefit, the amount of which is
limited in any pension or profit-sharing plan. Because the Death Benefit may
exceed this limitation, employers using the Contract in connection with such
plans should consult their tax adviser.

<PAGE>   48
   
      Tax Sheltered Annuities under section 403(b) of the Code allow employees
of certain Section 501(c)(3) organizations and public schools to exclude from
their gross income the premium payments made, within certain limits, on a
contract that will provide an annuity for the employee's retirement. These
premium payments may be subject to FICA (social security) tax. 

Distributions of (1) salary reduction contributions made in years beginning
after December 31, 1988; (2) earnings on those contributions; and (3) earnings
on amounts held as of the last year beginning before January 1, 1989, are not
allowed prior to age 59 1/2, separation from service, death or disability.
Salary reduction contributions may also be distributed upon hardship, but would
generally be subject to penalties.

      Section 457 Plans, while not actually providing for a qualified plan as
that term is normally used, provides for certain deferred compensation plans
with respect to service for state governments, local governments, political
subdivisions, agencies, instrumentalities and certain affiliates of such
entities, and tax exempt organizations. The Contract can be used with such
plans. Under such plans a participant may specify the form of investment in
which his or her participation will be made. All such investments, however, are
owned by and are subject to, the claims of the general creditors of the
sponsoring employer. In general, all amounts received under a section 457 plan
are taxable and are subject to federal income tax withholding as wages.

      Other Tax Issues. Qualified Contracts have minimum distribution rules that
govern the timing and amount of distributions. You should refer to your
retirement plan, adoption agreement, or consult a tax advisor for more
information about these distribution rules.

      Distributions from Qualified Contracts generally are subject to
withholding for the Owner's federal income tax liability. The withholding rate
varies according to the type of distribution and the Owner's tax status. The
Owner will be provided the opportunity to elect not have tax withheld from
distributions.

      "Eligible rollover distributions" from section 401(a) plans are subject to
a mandatory federal income tax withholding of 20%. An eligible rollover
distribution is the taxable portion of any distribution from such a plan, except
certain distributions such as distributions required by the Code or
distributions in a specified annuity form. The 20% withholding does not apply,
however, if the Owner chooses a "direct rollover" from the plan to another
tax-qualified plan or IRA.

POSSIBLE TAX LAW CHANGES

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

      We have the right to modify the contract in response to legislative
changes that could otherwise diminish the favorable tax treatment that annuity
contract owners currently receive. We make no guarantee regarding the tax status
of any contact and do not intend the above discussion as tax advice.

                              GENDER NEUTRALITY

      In 1983, the United States Supreme Court held 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. The Court applied its decision to benefits derived from
contributions made on or after August 1, 1983. Lower federal courts have since
held that the Title VII prohibition of sex-distinct benefits may apply at an
earlier date. In addition, some states prohibit using sex-distinct mortality
tables.

      The Contract uses sex-distinct actuarial tables, unless state law requires
the use of sex-neutral actuarial tables. As a result, the Contract generally
provides different benefits to men and women of the same age. Employers and
employee organizations which may consider buying Contracts in connection with
any employment-related insurance or benefits program should consult their legal
advisors to determine whether the Contract is appropriate for this purpose.

                                  VOTING RIGHTS

      Voting rights under the Contracts apply only with respect to Net Premium
Payments or accumulated amounts allocated to the Variable Account.

      In accordance with our view of present applicable law, we vote the shares
of the Funds held in the Variable Account at regular and special meetings of the
shareholders of the Funds. These shares are voted in accordance with
instructions received from you if you have an interest in the Variable 
Account. If the Investment Company Act or any regulation thereunder should be
amended or if the present interpretation thereof should change, and as a result
we determine that we are permitted to vote the shares of the Funds in our own
right, we may elect to do so.

      The person having the voting interest under a Contract is the Owner. The
number of Fund shares attributable to each Owner is determined by dividing the
Owner's interest in each Subaccount by the net asset value of the Fund
corresponding to the Subaccount.                                

      We determine the number of shares which a person has the right to vote on
a date we choose not more than 90 days prior to the meeting of the Fund. We
solicit voting instructions by written communication at least 21 days prior to
such meeting.    

      We vote Fund shares held in the Variable Account as to which no timely
instructions are received in the same proportions as to the voting instructions
we receive with respect to all contracts participating in the Variable Account.

      Each person having a voting interest will receive periodic reports
relating to the Funds, proxy material and a form with which to give such voting
instructions.

                            CHANGES TO VARIABLE ACCOUNT

      We reserve the right to create one or more new separate accounts, combine
or substitute separate accounts, or to add new investment Funds for use in the
Contracts at any time. In addition, if the shares of the Funds described in this
Prospectus should no longer be available for investment by the Variable Account
or, if in our judgment further investment in such Fund shares should become
inappropriate, we may eliminate Subaccounts, combine two or more Subaccounts or
substitute one or more Funds for other Fund shares already purchased or to be
purchased in the future under the Contract. No substitution of securities in the
Variable Account may take place without prior approval of the Securities and
Exchange Commission and under such requirements as it may impose. We may also
operate the Variable Account as a management investment company under the
Investment Company Act, deregister the Variable Account under the Investment
Company Act (if such registration is no longer required), transfer all or part
of the assets of the Variable Account to another



                                       45

separate account or to the Fixed Account (subject to obtaining all necessary
regulatory approvals), and make any other changes reasonably necessary under the
Investment Company Act or applicable state law.

                                    ADVERTISING

YIELD

      A "yield" and "effective yield" may be advertised for the Market Street
Money Market Portfolio Subaccount. "Yield" is a measure of the net dividend and
interest income earned over a specific seven-day period (which period will be
stated in the advertisement) expressed as a percentage of the offering price of
the Subaccount's units. Yield is an annualized figure, which means that it is
assumed that the Subaccount generates the same level of net income over a
52-week period. The "effective yield" is calculated similarly but includes the
effect of assumed compounding, calculated under rules prescribed by the
Securities and Exchange Commission. The effective yield will be slightly higher
than yield due to this compounding effect.

PERFORMANCE

       We may also from time to time advertise the performance of the
Subaccounts of the Variable Account relative to the performance of other
variable annuity subaccounts or funds with similar or different objectives, or
the investment industry as a whole. Other investments to which the Subaccounts
may be compared include, but are not limited to: precious metals; real estate;
stocks and bonds; closed-end funds; CDs; bank money market deposit accounts and
passbook savings; and the Consumer Price Index.

      Market Comparisons. The Subaccounts of the Variable Account may also be
compared to certain market indexes, which may include, but are not limited to:
S&P 500; Shearson/Lehman Intermediate Government/Corporate Bond Index;
Shearson/Lehman Long-Term Government/Corporate Bond Index; Donoghue Money Fund
Average; U.S. Treasury Note Index; Bank Rate Monitor National Index of 2 Year CD
Rates; and Dow Jones Industrial Average.

      Normally these rankings and ratings are published by independent tracking
services and publications of general interest including, but not limited to:
Lipper Analytical Services, Inc., CDA/ Wiesenberger, Morningstar, Donoghue's;
magazines such as Money, Forbes, Kiplinger's Personal Finance Magazine,
Financial World, Consumer Reports, Business Week, Time, Newsweek, National
Underwriter, U.S. News and World Report; rating services such as LIMRA, Value,
Best's Agent Guide, Western Annuity Guide, Comparative Annuity Reports; and
other publications such as the Wall Street Journal, Barron's, Investor's Daily,
and Standard & Poor's Outlook. In addition, Variable Annuity Research & Data
Service (The VARDS Report) is an independent rating service that ranks over 500
variable annuity funds based upon total return performance. These rating
services and publications rank the performance of the Funds against all funds
over specified periods and against funds in specified categories. The rankings
may or may not include the effects of sales or other charges.

      Rating Services. We are also ranked and rated by independent financial
rating services, among which are Moody's, Standard & Poor's and A.M. Best. The
purpose of these ratings is to reflect our financial strength or claims-paying
ability. The ratings are not intended to reflect the investment experience or
financial strength of the Variable Account. We may advertise these ratings from
time to time. In addition, we may include in certain advertisements,
endorsements in the form of a list of organizations, individuals or other
parties which recommend us or the Contracts. Furthermore, we may occasionally
include in advertisements comparisons of currently taxable and tax deferred
investment programs, based on selected tax brackets, or discussions of
alternative investment vehicles and general economic conditions.

      Historical Performance. We may from time to time advertise several types
of historical performance for the Subaccounts of the Variable Account. We may
advertise for the Subaccounts standardized "average annual total return,"
calculated in a manner prescribed by the Securities and Exchange Commission, and
nonstandardized "total return."
   
      Standardized Average Annual Total Return.. "Standardized Average Annual 
      Total Return" will show the percentage rate of return of a hypothetical 
      initial investment of $1,000 for at least the most recent one, five and 
      ten year period, or for a period covering the time the Subaccount has
      been in existence, if the Subaccount has not been in existence for one of
      the prescribed periods. This calculation reflects the deduction of all
      applicable charges made to the Contracts except for premium taxes, which
      may be imposed by certain states.
    

   
            The charts below show Standardized Average Annual Total Return for
      the Subaccounts for the indicated periods. For the purposes of calculating
      Standardized Average Annual Total Return, the Mortality and Expense Risk
      Charge of 1.25%, the Administration Charge of 0.15%, the Annual Contract
      Fee of $30.00, the applicable CDSC and the optional Enhanced Death 
      Benefit Charge of 0.20% were deducted.
    
            Based on the method of calculation described above, the Standardized
      Average Annual Total Returns for the Subaccounts for the periods ending
      December 31, 1998 were:

      Other Total Returns.  Other "total returns" include nonstandardized
      Subaccount average annual total returns and adjusted historic fund 
      performance data.
    

   
            Nonstandardized Average Annual Total Return.
      Nonstandardized "Average Annual Total Return" will be calculated 
      in a similar manner and for the same time periods as the standardized 
      average annual total return but will assume an initial investment of 
      $10,000 and will not reflect the deduction of any applicable
      CDSC which, if reflected, would decrease the level of performance shown.
      The Contingent Deferred Sales Charge is not reflected because the
      Contracts are designed for long term investment. An assumed initial
      investment of $10,000 will be used because that figure more closely
      approximates the size of a typical Contract than does the $1,000 figure
      used in calculating the Standardized Average Annual Total Return
      quotations. Nonstandardized performance data will only be disclosed if 
      standardized average annual total return for the Subaccounts for the 
      required periods is also disclosed.
    

   
            The charts below show Nonstandardized Average Annual Total Return
      for the Subaccounts for the indicated periods. For the purposes of
      calculating Nonstandardized Average Annual Total Return, the Mortality and
      Expense Risk Charge of 1.25%, the Administration Charge of 0.15%, the 
      Annual Contract Fee of $30.00, and the optional Enhanced Death Benefit 
      Rider Charge of 0.20% were deducted.
    

            Based on the method of calculation described above, the
      Nonstandardized Subaccount Average Annual Total Returns for the
      Subaccounts for the period ending December 31, 1998, were:

      All performance information and comparative material advertised by
National Life is historical in nature and is not intended to represent or
guarantee future results. An Owner's Contract Value at redemption may be more or
less than original cost.

                         DISTRIBUTION OF THE CONTRACTS

      The principal underwriter for the contracts is ESI, which is an
SEC-registered broker-dealer firm and is a member of the National Association of
Securities Dealers, Inc. ESI is a wholly-owned subsidiary of National Life. It
distributes a full line of securities products, including mutual funds, unit
investment trusts, and variable insurance contracts, and provides individual
securities brokerage services. The maximum commission payable for selling the
Contracts will be 6.5%.

                   INSURANCE MARKETPLACE STANDARDS ASSOCIATION

        National Life Insurance Company is a member of the Insurance Marketplace
Standards Association ("IMSA"), and as such may include the IMSA logo and
information about IMSA membership in its advertisements. Companies that belong
to IMSA subscribe to a set of ethical standards covering the various aspects of
sales and service for individually sold life insurance and annuities.

                            STATEMENTS AND REPORTS

      National Life will mail to Owners, at their last known address of record,
any statements and reports required by applicable laws or regulations. Owners
should therefore give National Life prompt notice of any address change.
National Life will send a confirmation statement to Owners each time a
transaction is made affecting the Owner's Variable Account Contract Value, such
as making additional Premium Payments, transfers, exchanges or Withdrawals.
Quarterly statements are also mailed detailing the Contract activity during the
calendar quarter. Instead of receiving an immediate confirmation of transactions
made pursuant to some types of periodic payment plans (such as a dollar cost
averaging program) or salary reduction arrangement, the Owner may receive
confirmation of such transactions in their quarterly statements. The Owner
should review the information in these statements carefully. All errors or
corrections must be reported to National Life immediately to assure proper
crediting to the Owner's Contract. National Life will assume all transactions
are accurately reported on quarterly statements or confirmation statements
unless the Owner notifies National Life otherwise within 30 days after receipt
of the statement. National Life will also send to Owners each year an annual
report and a semi-annual report containing financial statements for the Variable
Account, as of December 31 and June 30, respectively.

                            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, National Life utilizes computer
systems that may be effected by Year 2000 transition issues, and National Life
relies on service providers, including the Funds, that also may be affected.
National Life has developed, and is in the process of implementing, a Year 2000
transition plan, and is confirming that its 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 National Life. However, as of the date of this prospectus, it is not
anticipated that any Policy Owners will experience negative effects on their
investment, or on the services provided in connection therewith, as a result of
Year 2000 transition implementation. National Life currently anticipates that
its computer systems will be



                                       51

Year 2000 compliant on or about January 1, 1999, but there can be no assurance
that National Life will be successful, or that interaction with other service
providers will not impair National Life's services at that time.

                                OWNER INQUIRIES

      Owner inquiries may be directed to National Life Insurance Company by

                               LEGAL PROCEEDINGS

      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 $40.6 million to account for the cost of
the settlement of these cases. National Life is a 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
Contracts. ESI is not engaged in any litigation of any material nature.

                         NATIONAL LIFE INSURANCE COMPANY

         National Life Insurance Company ("National Life") has operated as a
mutual life insurance company since 1848 under a charter granted by the State of
Vermont, and has done business continuously as "National Life Insurance
Company."


                         ADDITIONAL CONTRACT PROVISIONS

The Contract

         The entire contract is made up of the Contract and the application. The
statements made in the application are deemed representations and not
warranties. National Life cannot use any statement in defense of a claim or to
void the Contract unless it is contained in the application and a copy of the
application is attached to the Contract at issue.

Misstatement of Age or Sex

         If the age or sex of the Chosen Human Being has been misstated, the 
amount which will be paid is that which is appropriate to the correct age
and sex.


Dividends

      The Contract is participating; however, no dividends are expected to be
paid on the Contract. If dividends are ever declared, they will be paid in cash.

Assignment

         Where permitted, the Owner may assign some or all of the rights under
the Contract at any time during the lifetime of the Annuitant prior to the
Annuitization Date. Such assignment will take effect upon receipt and recording
by National Life at its Home Office of a written notice executed by the Owner.
National Life assumes no responsibility for the validity or tax consequences of
any assignment. National Life shall not be liable as to any payment or other
settlement made by National Life before recording of the assignment. Where
necessary for the proper administration of the terms of the Contract, an
assignment will not be recorded until National Life has received sufficient
direction from the Owner and assignee as to the proper allocation of Contract
rights under the assignment.

         Any portion of Contract Value which is pledged or assigned shall be
treated as a Distribution and shall be included in gross income to the extent
that the cash value exceeds the investment in the Contract for the taxable year
in which assigned or pledged. In addition, any Contract Values assigned may,
under certain conditions, be subject to a tax penalty equal to 10% of the amount
which is included in gross income. 

                                       3
<PAGE>   65
entire Contract Value may cause the portion of the Contract Value which exceeds
the total investment in the Contract and previously taxed amounts to be included
in gross income for federal income tax purposes each year that the assignment is
in effect. Qualified Contracts are not eligible for assignment.




                     CALCULATION OF YIELDS AND TOTAL RETURNS

         From time to time, National Life may disclose yields, total returns,
and other performance data pertaining to the Contracts or a Subaccount. Such
performance data will be computed, or accompanied by performance data computed,
in accordance with the standards defined by the Securities and Exchange
Commission.

         Because of the charges and deductions imposed under a Contract, the
yield for the Subaccounts will be lower than the yield for their respective
Portfolios. The calculations of yields, total returns, and other performance
data do not reflect the effect of any premium tax that may be applicable to a
particular Contract. Premium taxes currently rate from 0% to 3.5% of premium
based on the state in which the Contract is sold.

Money Market Subaccount Yields

   
         From time to time, advertisements and sales literature may quote the
current annualized yield of the Money Market Subaccount for a seven-day period
in a manner which does not take into consideration any realized or unrealized
gains or losses, or income other than investment income, on shares of the Market
Street Money Market Portfolio or on its portfolio securities.
    

   
         This current annualized yield is computed by determining the net change
(exclusive of realized gains and losses on the sale of securities and unrealized
appreciation and depreciation), and exclusive of income other than investment
income at the end of the seven-day period in the value of a hypothetical account
under a Contract having a balance of 1 unit of the Money Market Subaccount at
the beginning of the period, dividing such net change in account value by the
value of the hypothetical account at the beginning of the period to determine
the base period return, and annualizing this quotient on a 365-day basis. The
net change in account value reflects: 1) net income from the Portfolio
attributable to the hypothetical account; and 2) charges and deductions imposed
under the Contract which are attributable to the hypothetical account. The
charges and deductions include the per unit charges for the hypothetical account
for: 1) the Annual Contract Fee; 2) Administration Charge; and 3) the Mortality
and Expense Risk Charge. For purposes of calculating current yields for a
Contract, an average per unit Annual Contract Fee is used based on the $30
Annual Contract Fee deducted at the beginning of each Contract Year. For the
class of Contracts with the Enhanced Death Benefit Rider, the charge for that
optional benefit will be included. Current Yield will be calculated according to
the following formula:
    

         Current Yield = ((NCS - ES) /UV) x (365/7)

         Where:
   
         NCS           = the net change in the value of the Portfolio
                       (exclusive of realized gains or losses on the sale of
                       securities and unrealized appreciation and
    
                                       4

<PAGE>   66
   
                       depreciation, and exclusive of income other than
                       investment income) for the seven-day period attributable
                       to a hypothetical account having a balance of 1
                       Subaccount unit.
    
         ES =          per unit expenses attributable to the hypothetical 
                       account for the seven-day period.

         UV =          The unit value on the first day of the seven-day period.

         The effective yield of the Money Market Subaccount determined on a
compounded basis for the same seven-day period may also be quoted.

         The effective yield is calculated by compounding the unannualized base
period return according to the following formula:

                                               365/7
         Effective Yield = (1 + (NCS - ES)/UV))      - 1

         Where:

   
         NCS =         the net change in the value of the Portfolio (exclusive 
                       of realized gains or losses on the sale of securities and
                       unrealized appreciation and depreciation, and exclusive
                       of income other than investment income) for the seven-
                       day period attributable to a hypothetical account having
                       a balance of 1 Subaccount unit.
    

         ES =          per unit expenses attributable to the hypothetical 
                       account for the seven day period.

         UV =          The unit value on the first day of the seven-day period.

         Because of the charges and deductions imposed under the Contract, the
yield for the Money Market Subaccount will be lower than the yield for the
Market Street Money Market Portfolio.

   
         The current yield for the Money Market Subaccount as of December 31,
1998 was ____%,and the effective yield for that Subaccount as of the same date
was ____%. These yields were calculated based on the performance of the Market
Street Money Market Portfolio for the seven days ended December 31, 1998, and
the assumption that the Money Market Subaccount was in existence for this
period with the level of Contract charges that was in effect at the inception
of the Money Market Subaccount.
    

         The current and effective yields on amounts held in the Money Market
Subaccount normally will fluctuate on a daily basis. THEREFORE, THE DISCLOSED
YIELD FOR ANY GIVEN PAST PERIOD IS NOT AN INDICATION OR REPRESENTATION OF FUTURE
YIELDS OR RATES OF RETURN. The Money Market Subaccount's actual yield is
affected by changes in interest rates on money market securities, average
portfolio maturity of the Market Street Money Market Portfolio, the types of
quality of portfolio securities held by the Market Street Money Market Portfolio
and the Market Street Money Market Portfolio's operating expenses. Yields on
amounts held in the Money Market Subaccount may also be presented for periods
other than a seven-day period.

Other Subaccount Yields

         From time to time, sales literature or advertisements may quote the
current annualized yield of one or more of the Subaccounts (except the Money
Market Subaccount) for a Contract for 30-day or one-month periods. The
annualized yield of a Subaccount refers to income generated by the Subaccount
over a specific 30-day or one-month period. Because the yield is annualized, the
yield generated by a Subaccount during a 30-day or one-month period is assumed
to be generated each period over a 12-month period.


                                       5

<PAGE>   67
         The yield is computed by: 1) dividing the net investment income of the
Portfolio attributable to the Subaccount units less Subaccount expenses for the
period; by (2) the maximum offering price per unit on the last day of the period
times the daily average number of units outstanding for the period; by 3)
compounding that yield for a six-month period; and by 4) multiplying that result
by 2. Expenses attributable to the Subaccount include the Annual Contract Fee,
the Administration Charge and the Mortality and Expense Risk Charge. For the
class of Contracts with the Enhanced Death Benefit Rider, the charge for that
optional benefit will be included. For purposes of calculating the 30-day or
one -month yield, an average Annual Contract Fee per dollar of Contract Value
in the Variable Account is used to determine the amount of the charge
attributable to the Subaccount for the 30-day or one-month period. The 30-day
or one-month yield is calculated according to the following formula:

                                               6
         Yield = 2 x (((NI - ES)/(U x UV)) + 1) -1)

         Where:

         NI = net income of the Portfolio for the 30-day or one-month period
         attributable to the Subaccount's units.

         ES = expenses of the Subaccount for the 30-day or one-month period.

         U  = the average number of units outstanding.

         UV = the unit value at the close (highest) of the last day in the
30-day or one-month period.

         Because of the charges and deductions imposed under the Contracts, the
yield for the Subaccount will be lower than the yield for the corresponding
Fund.

         The yield on the amounts held in the Subaccounts normally will
fluctuate over time. Therefore, the disclosed yield for any given past period is
not an indication or representation of future yields or rates of return. The
Subaccount's actual yield is affected by the types and quality of portfolio
securities held by the Portfolio and its operating expenses.

         Yield calculations do not take into account the Surrender Charge under
the Contract equal to from 1% to 7% of premiums paid during the seven years
prior to the surrender or Withdrawal (including the year in which the surrender
is made) on amounts surrendered or withdrawn under the Contract. A Surrender
Charge will not be imposed on Withdrawals in any Contract Year on an amount up
to 15% of the Contract Value as of the most recent Contract Anniversary.
However, if a Contract is subsequently surrendered within a year after taking a
Withdrawal that benefits from the CDSC-free provision, then a CDSC will be
assessed at the time of the surrender as if the surrender had been taken as a
single step.

   
Total Returns
    




                                       6

<PAGE>   68

   
         From time to time, sales literature or advertisements may also quote
total returns for periods after or prior to the date the Variable Account
commenced operations. For periods prior to the date the Variable Account
commenced operations, performance information for the Contracts will be
calculated based on the performance of the Fund Portfolios and the assumption
that the Subaccounts were in existence for the same periods with the level of
Contract charges that were in effect at the inception of the Subaccounts.
    

   
A. Standardized Average Annual Total Returns

         Average annual total returns represent the average annual compounded
rates of return that would equate an initial investment of $1,000 under a
Contract to the redemption value of that investment as of the last day of each
of the periods. The ending date for each period for which total return
quotations are provided will be for the most recent month-end practicable,
considering the type and media of the communication and will be stated in the
communication.
    

   
            Standardized Average Annual Total Return is calculated using
Subaccount unit values which we calculate on each Valuation Day based on the
performance of the Subaccount's underlying fund, the deductions for the
Mortality and Expense Risk Charge, the deductions for the asset-based
Administration Charge and the policy fee. For purposes of calculating average
annual total return, an average per dollar Annual Contract Fee attributable to
the hypothetical account for the period is used. The calculation also assumes
surrender of the Contract at the end of the period for the return quotation.
Total returns will therefore reflect a deduction of the CDSC for any period less
than seven years. The average annual total return will then be calculated
according to the following formula:
    

         TR =     ( ( ERV/P) 1/N) - 1

         Where:

         TR =         the average annual total return net of Subaccount 
                      recurring charges.

         ERV=         the ending redeemable value (net of any applicable
                      surrender charge) of the hypothetical account at the end
                      of the period.

         P  =         a hypothetical initial payment of $1,000.

         N  =         the number of years in the period.


   
    

         Average annual total return may be calculated either taking into
account or not taking into account the impact of the Enhanced Death Benefit
Rider.


                                      7
<PAGE>   69
         Such average annual total return information for the Subaccounts is set
forth in the Prospectus.

   
         B. Other Total Returns
    

   
         Nonstandardized Subaccount Average Annual Total Return. From time to 
time, sales literature or advertisements may also quote nonstandardized average
annual total returns for the Subaccounts that do not reflect the CDSC. These are
calculated in exactly the same way as average annual total returns described
above, except that the ending redeemable value of the hypothetical account for
the period is replaced with an ending value for the period that does not take
into account any charges on amounts surrendered or withdrawn, and that the
initial investment is assumed to be $10,000 rather than $1,000. Such information
is also set forth in the Prospectus.
    

   
         Cumulative Subaccount Total Return. National Life may disclose 
Cumulative Total Returns in conjunction with the standard formats described
above. The Cumulative Total Returns will be calculated using the following
formula:
    

         CTR =        (ERV/P) - 1

Where:
         CTR =        The Cumulative Total Return net of Subaccount recurring 
                      charges for the period.

         ERV =        The ending redeemable value of the hypothetical investment
                      at the end of the period.

         P =          A hypothetical single payment of $1,000.

   
         Adjusted Historic Fund Performance. Sales literature or
advertisements may quote nonstandardized "adjusted" total returns for the Funds
since their inception reduced by some or all of the fees and charges under the
Policy. Such adjusted historic fund performance includes data that precedes the
inception dates of the Subaccounts. This data is designed to show the
performance that would have resulted if the Policy had been in existence during
that time.
    

   
         When the standard performance data for the Subaccounts is available,
nonstandardized Subaccount and adjusted historic Fund performance data will be
disclosed together with the standard performance data for the required periods.
    

   
         The Funds have provided the total return information, which includes
the adjusted historic Fund total return information used to calculate the
adjusted historic total returns of the Funds Subaccounts for periods prior to
the inception of the Subaccounts. The Alger American Fund, Variable Insurance
Products Fund, Variable Insurance Product Fund II, Strong Special Fund II, Inc.,
Strong Variable Insurance Funds, Inc. , American Century Investment Management,
Inc., Neuberger & Berman Advisers Management Trust, J. P. Morgan Series Trust II
and Goldman Sachs Variable Insurance Trust, are not affiliated with us.
    

   
         Such adjusted historic total return information for the Funds is set
forth in the Prospectus.
    

Effect of the Annual Contract Fee on Performance Data

         The Contract provides, for all Contracts with a Contract Value of less
than $50,000 on the Date of Issue or any subsequent Contract Anniversary, for a
$30 Annual Contract Fee to be deducted annually at the beginning of each
Contract Year, from the Subaccounts and the unloaned portion of the Fixed
Account based on the proportion that the value of each such account bears to
the total Contract Value. For purposes of reflecting the Annual Contract Fee in
the yield and total return quotations, the Annual Contract Fee is converted
into a per-dollar per-day charge. The per-dollar per-day charge has been
estimated based on the distribution of National Life's non-variable single
premium deferred annuity block of business.

                                       8
<PAGE>   70
The per-dollar per-day average charge will then be adjusted to reflect the
basis upon which the particular quotation is calculated.


                          DISTRIBUTION OF THE CONTRACTS

   
        The principal underwriter for the Contracts is Equity Services, Inc.
ESI, a wholly-owned subsidiary of the Company and a member of the National
Association Securities, Inc. ESI also serves as principal underwriter of the
National Variable Life Insurance Account and the Life of the Southwest LSW
Variable Annuity Account I, which are unit investment trusts registered under
the Investment Company Act of 1940. The Contracts will be offered on a
continuous basis and will be sold by licensed insurance agents in the states
where the Contracts may lawfully be sold. Such agents will be representatives of
broker-dealers registered under the Securities Exchange Act of 1934 who are
members of the National Association of Securities Dealers, Inc. Broker-dealers
other than ESI will have executed Selling Agreements with ESI. As principal
underwriter of the Variable Accounts, ESI received and retained underwriting
commissions of _____ in 1998.

Item 27. Number of Contract Owners

Item 28. Indemnification

         The By-Laws of Depositor provide, in part in Article VI, as follows:

         Article 6.02
   
         7.1  Indemnification.

         (a) The Corporation shall indemnify and hold harmless any officer,
         director, employee or agent of the Corporation to the fullest extent
         permitted under Title 11A, Chapter 8, Subchapter 5 of the Vermont
         Statutes Annotated, as the same may be amended from time to time. Any
         repeal or modification of this Section 7.1 or of Title 11A, Chapter 8,
         Subchapter 5 of the Vermont Statutes Annotated shall not adversely
         affect any right of indemnification of any officer, director or
         employee of the Corporation existing at any time prior to such repeal
         or modification. Provided, however, that the Corporation shall not be
         required to indemnify a person in connection with a proceeding
         initiated by such person, including a counterclaim or crossclaim,
         unless the proceeding was authorized by the Board of Directors.

         (b) The Corporation may pay or reimburse the reasonable expenses
         incurred in defending any proceeding in advance of its final
         disposition if the Corporation has received in advance an undertaking
         by the person receiving such payment or reimbursement to repay all
         amounts advanced if it should be ultimately determined that he or she
         is not entitled to be indemnified under this article or otherwise. The
         Corporation may require security for any such undertaking.
    

         Insofar as indemnification for liabilities arising under the Securities
         Act of 1933 may be permitted to directors, officers, and controlling
         persons of the Registrant pursuant to the foregoing provisions, or
         otherwise, the Registrant has been advised that in the opinion of the
         Securities and Exchange Commission such indemnification



                                      C-5






<PAGE>   78
         is against public policy as expressed in the Act and is, therefore,
         unenforceable. In the event that a claim for indemnification against
         such liabilities (other than the payment by the Registrant of expenses
         incurred or paid by a director, officer or controlling person of the
         Registrant in the successful defense of any such 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 of 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.


Item 29  Principal Underwriter

         (a) Equity Services, Inc. (ESI) is the principal underwriter for
             National Variable Annuity Account II and National Variable Life

any applicable state laws, necessary in the best interests of the shareholders
of such Portfolio.

invested in the Fund, in such other Funds advised by the Adviser as may be
mutually agreed to in writing by the parties hereto, or in the Company's general
account, provided that such amounts may also be invested in an investment
company other than the Fund if (a) such other investment company, or series
thereof, has investment objectives or policies that are substantially different

continues to interpret the Investment Company Act to require pass-through voting
privileges for variable contract owners. The Company reserves the right to vote
Fund shares held in any segregated asset account in its own right, to the extent
permitted by law. Participating Insurance Companies shall be responsible for

requiring voting by shareholders, and in particular the Fund will either provide
for annual meetings or comply with Section 16(c) of the 1940 Act (although the
Fund is not one of the trusts described in Section 16(c) of that Act) as well as
with Sections 16(a) and, if and when applicable, 16(b).

           4.5. The Fund will provide to the Company at least one complete copy

display, signs or billboards, motion pictures, or other public media), sales

available to customers or the public, including brochures, circulars, research
reports, market letters, form letters, seminar texts, reprints or excerpts of
any other advertisement, sales literature, or published article), educational or
training materials or other communications distributed or made generally
available to some or all agents or employees, and registration statements,
prospectuses, Statements of Additional Information, shareholder reports, and

ARTICLE V. Fees and Expenses

           5.1. The Fund and Underwriter shall pay no fee or other compensation
to the Company under this agreement, except that if the Fund or any Portfolio
adopts and implements a plan pursuant to Rule 12b-l to finance distribution
expenses, then the Underwriter may make payments to the Company or to the
underwriter for the Contracts if and in amounts agreed to by the Underwriter in
writing and such payments will be made out of existing fees otherwise payable to
the Underwriter, past profits of the Underwriter or other resources available to
the Underwriter. No such payments shall be made directly by the Fund. Currently,
no such payments are contemplated.

           5.2. All expenses incident to performance by the Fund under this
Agreement shall be paid by the Fund. The Fund shall see to it that all its
shares are registered and authorized for issuance in accordance with applicable
federal law and, if and to the extent deemed advisable by the Fund, in

the expenses for the cost of registration and qualification of the Fund's
shares, preparation and filing of the Fund's prospectus and registration




                                      -14-
<PAGE>   15

statement, proxy materials and reports, setting the prospectus in type, setting

           5.3. The Company shall bear the expenses of printing and distributing
the Fund's prospectus to owners of Contracts issued by the Company and of
distributing the Fund's proxy materials and reports to such Contract owners.


ARTICLE VI. Diversification

           6.1. The Fund will at all times invest money from the Contracts in
such a manner as to ensure that the Contracts will be treated as variable
contracts under the Code and the regulations issued thereunder. Without limiting
the scope of the foregoing, the Fund will at all times comply with Section
817(h) of the Code and Treasury Regulation Section 1.817-5 relating to the
diversification requirements for variable annuity, endowment, or life insurance
contracts and any amendments or other modifications to such Section or
Regulations.


ARTICLE VII. Potential Conflicts

           7.1. The Board of Trustees of the Fund (the "Board") will monitor the
Fund for the existence of any material irreconcilable conflict between the
interests of the contract owners of all separate accounts investing in the Fund.
An irreconcilable material conflict may arise for a variety of reasons,
including: (a) an action by any state insurance regulatory authority; (b) a
change in applicable federal or state insurance, tax, or securities laws or




                                      -15-
<PAGE>   16

regulations, or a public ruling, private letter ruling, no-action or
interpretative letter, or any similar action by insurance, tax, or securities
regulatory authorities; (c) an administrative or judicial decision in any
relevant proceeding; (d) the manner in which the investments of any Portfolio
are being managed; (e) a difference in voting instructions given by variable
annuity contract and variable life insurance contract owners; or (f) a decision
by an insurer to disregard the voting instructions of contract owners. The Board
shall promptly inform the Company if it determines that an irreconcilable
material conflict exists and the implications thereof.

           7.2. The Company will report any potential or existing conflicts of
which it is aware to the Board. The Company will assist the Board in carrying
out its responsibilities under the Shared Funding Exemptive Order, by providing
the Board with all information reasonably necessary for the Board to consider
any issues raised. This includes, but is not limited to, an obligation by the
Company to inform the Board whenever contract owner voting instructions are
disregarded.

           7.3. If it is determined by a majority of the Board, or a majority of
its disinterested trustees, that a material irreconcilable conflict exists, the
Company and other Participating Insurance Companies shall, at their expense and
to the extent reasonably practicable (as determined by a majority of the
disinterested trustees), take whatever steps are necessary to remedy or
eliminate the irreconcilable material conflict, up to and including: (1),
withdrawing the assets allocable to some or all of the separate accounts from
the Fund or any Portfolio and reinvesting such assets in a different investment
medium, including (but not limited to) another Portfolio of the Fund, or
submitting the question whether such segregation should be implemented to a vote
of all affected contract owners and, as appropriate,




                                      -16-
<PAGE>   17

segregating the assets of any appropriate group (i.e., annuity contract owners,
life insurance contract owners, or variable contract owners of one or more
Participating Insurance Companies) that votes in favor of such segregation, or
offering to the affected contract owners the option of making such a change; and
(2), establishing a new registered management investment company or managed
separate account.

           7.4. If a material irreconcilable conflict arises because of a
decision by the Company to disregard contract owner voting instructions and that
decision represents a minority position or would preclude a majority vote, the
Company may be required, at the Fund's election, to withdraw each Account's
investment in the Fund and terminate this Agreement; provided, however that such
withdrawal and termination shall be limited to the extent required by the
foregoing material irreconcilable conflict as determined by a majority of the
disinterested members of the Board. Any such withdrawal and termination must
take place within six (6) months after the Fund gives written notice that this
provision is being implemented, and until the end of that six month period the
Underwriter and Fund shall continue to accept and implement orders by the
Company for the purchase (and redemption) of shares of the Fund.

           7.5. If a material irreconcilable conflict arises because a
particular state insurance regulator's decision applicable to the Company
conflicts with the majority of other state regulators, then the Company will
withdraw each Account's investment in the Fund and terminate this Agreement
within six months after the Board informs the Company in writing that it has
determined that such decision has created an irreconcilable material conflict;
provided, however, that such withdrawal and termination shall be limited to the
extent required by the foregoing material irreconcilable conflict as determined
by a majority of the disinterested members of the Board. Until the



                                      -17-
<PAGE>   18

end of the foregoing six month period, the Underwriter and Fund shall continue
to accept and implement orders by the Company for the purchase (and redemption)
of shares of the Fund.

            7.6. For purposes of Sections 7.3 through 7.6 of this Agreement, a
majority of the disinterested members of the Board shall determine whether any
proposed action adequately remedies any irreconcilable material conflict, but in
no event will the Fund be required to establish a new funding medium for the
Contracts. The Company shall not be required by Section 7.3 to establish a new
funding medium for the Contracts if an offer to do so has been declined by vote
of a majority of Contract owners materially adversely affected by the
irreconcilable material conflict. In the event that the Board determines that
any proposed action does not adequately remedy any irreconcilable material
conflict, then the Company will withdraw each Account's investment in the Fund
and terminate this Agreement within six (6) months after the Board informs the
Company in writing of the foregoing determination, provided, however, that such
withdrawal and termination shall be limited to the extent required by any such
material irreconcilable conflict as determined by a majority of the
disinterested members of the Board.

           7.7. If and to the extent that Rule 6e-2 and Rule 6e-3(T) are
amended, or Rule 6e-3 is adopted, to provide exemptive relief from any provision
of the Act or the rules promulgated thereunder with respect to mixed or shared
funding (as defined in the Shared Funding Exemptive Order) on terms and
conditions materially different from those contained in the Shared Funding
Exemptive Order, then (a) the Fund and/or the Participating Insurance Companies,
as appropriate, shall take such steps as may be necessary to comply with Rules
6e-2 and 6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such
rules are applicable; and (b) Sections 3.4, 3.5, 7.1, 7.2, 7.3,




                                      -18-
<PAGE>   19

7.4, and 7.5 of this Agreement shall continue in effect only to the extent
that terms and conditions substantially identical to such Sections are
contained in such Rule(s) as so amended or adopted.

           8.1(a). The Company agrees to indemnify and hold harmless the Fund

losses, claims, damages, liabilities (including amounts paid in settlement with
the written consent of the Company) or litigation (including legal and other
expenses), to which the Indemnified Parties may become subject under any
statute, regulation, at common law or otherwise, insofar as such losses, claims,
damages, liabilities or expenses (or actions in respect thereof) or settlements
are related to the sale or acquisition of the Fund's shares or the Contracts
and:

              (i) arise out of or are based upon any untrue statements or
              alleged untrue statements of any material fact contained in the
              Registration Statement or prospectus for the Contracts or
              contained in the Contracts or sales literature for the Contracts
              (or any amendment or supplement to any of the foregoing), or arise
              out of or are based upon the omission or the alleged omission to
              state therein a material fact required to be stated therein or
              necessary to make the statements therein not misleading, provided
              that this agreement to indemnify shall not apply as to any
              Indemnified Party if such statement or omission



                                      -19-
<PAGE>   20
                or such alleged statement or omission was made in reliance upon

                or prospectus for the Contracts or in the Contracts or sales
                literature (or any amendment or supplement) or otherwise for use
                in connection with the sale of the Contracts or Fund shares; or 

                (ii) arise out of or as a result of statements or
                representations (other than statements or representations
                contained in the Registration Statement, prospectus or sales
                literature of the Fund not supplied by the Company, or persons
                under its control) or wrongful conduct of the Company or persons
                under its control, with respect to the sale or distribution of
                the Contracts or Fund Shares; or

                (iii) arise out of any untrue statement or alleged untrue
                statement of a material fact contained in a Registration
                Statement, prospectus, or sales literature of the Fund or any
                amendment thereof or supplement thereto or the omission or
                alleged omission to state therein a material fact required to be
                stated therein or necessary to make the statements therein not
                misleading if such a statement or omission was made in reliance
                upon information furnished to the Fund by or on behalf of the
                Company: or

                (iv) arise as a result of any failure by the Company to provide
                the services and furnish the materials under the terms of this
                Agreement; or

                (v) arise out of or result from any material breach of any

                                      -20-
<PAGE>   21

              Agreement or arise out of or result from any other material breach
              of this Agreement by the Company,

as limited by and in accordance with the provisions of Sections 8.1(b) and
8.1(c) hereof.

           8.1(b). The Company shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
to which an Indemnified Party would otherwise be subject by reason of such
Indemnified Party's willful misfeasance, bad faith, or gross negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of obligations or duties under this Agreement or to
the Fund, whichever is applicable.

          8.1(c). The Company shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified the Company in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify the Company of any
such claim shall not relieve the Company from any liability which it may have to
the Indemnified Party against whom such action is brought otherwise than on
account of this indemnification provision. In case any such action is brought
against the Indemnified Parties, the Company shall be entitled to participate,
at its own expense, in the defense of such action. The Company also shall be
entitled to assume the defense thereof, with counsel satisfactory to the party
named in the action. After notice from the Company to such party of the
Company's election to assume the defense thereof, the Indemnified Party shall
bear the fees and expenses of any additional counsel




                                      -21-

Agreement for any legal or other expenses subsequently incurred by such party
independently in connection with the defense thereof other than reasonable costs
of investigation.

           8.1(d). The Indemnified Parties will promptly notify the Company of
the commencement of any litigation or proceedings against them in connection
with the issuance or sale of the Fund Shares or the Contracts or the operation
of the Fund.

           8.2.  Indemnification by the Underwriter

           8.2 (a). The Underwriter agrees to indemnify and hold harmless the
Company and each of its directors and officers and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act
(collectively, the "Indemnified Parties" for purposes of this Section 8.2)
against any and all losses, claims, damages, liabilities (including amounts paid
in settlement with the written consent of the Underwriter) or litigation
(including legal and other expenses) to which the Indemnified Parties may become
subject under any statute, at common law or otherwise, insofar as such losses,
claims, damages, liabilities or expenses (or actions in respect thereof) or
settlements are related to the sale or acquisition of the Fund's shares or the
Contracts and:

              (i) arise out of or are based upon any untrue statement or alleged
              untrue statement of any material fact contained in the
              Registration Statement or prospectus or sales literature of the
              Fund (or any amendment or supplement to any of the foregoing), or

              omission to state therein a material fact required to be stated
              therein or necessary to make the statements therein not




                                      -22-
<PAGE>   23

misleading, provided that this agreement to indemnify shall not apply as to any
Indemnified Party if such statement or omission or such alleged statement or
omission was made in reliance upon and in conformity with information furnished
to the Underwriter or Fund by or on behalf of the Company for use in the
Registration Statement or prospectus for the Fund or in sales literature (or any
amendment or supplement) or otherwise for use in connection with the sale of the
Contracts or Fund shares: or 

(ii) arise out of or as a result of statements or representations (other than
statements or representations contained in the Registration Statement,
prospectus or sales literature for the Contracts not supplied by the
Underwriter or persons under its control) or wrongful conduct of the Fund,
Adviser or Underwriter or persons under their control, with respect to the sale
or distribution of the Contracts or Fund shares; or

(iii) arise out of any untrue statement or alleged untrue statement of a
material fact contained in a Registration Statement, prospectus, or sales
literature covering the Contracts, or any amendment thereof or supplement
thereto, or the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statement or statements
therein not misleading, if such statement or omission was made in reliance upon
information furnished to the Company by or on behalf of the Fund; or

(iv) arise as a result of any failure by the Fund to provide the services and
furnish the materials under the terms of this


                                      -23-
<PAGE>   24

               faith or otherwise, to comply with the diversification
               requirements specified in Article VI of this Agreement); or 

               (v) arise out of or result from any material breach of any
               representation and/or warranty made by the Underwriter in this
               Agreement or arise out of or result from any other material
               breach of this Agreement by the Underwriter;

as limited by and in accordance with the provisions of Sections 8.2(b) and
8.2(c) hereof.

           8.2(b). The Underwriter shall not be liable under this
indemnification provision with respect to any losses, claims, damages,
liabilities or litigation to which an Indemnified Party would otherwise be
subject by reason of such Indemnified Party's willful misfeasance, bad faith, or
gross negligence in the performance of such Indemnified Party's duties or by
reason of such Indemnified Party's reckless disregard of obligations and duties
under this Agreement or to the Company or each Account, whichever is applicable.

           8.2(c). The Underwriter shall not be liable under this
indemnification provision with respect to any claim made against an Indemnified
Party unless such Indemnified Party shall have notified the Underwriter in
writing within a reasonable time after the summons or other first legal process
giving information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify the Underwriter of
any such claim shall not relieve the Underwriter from any liability which it may
have to the Indemnified Party against whom such action is brought otherwise than
on account of this indemnification




                                      -24-

provision. In case any such action is brought against the Indemnified Parties,
the Underwriter will be entitled to participate, at its own expense, in the
defense thereof. The Underwriter also shall be entitled to assume the defense
thereof, with counsel satisfactory to the party named in the action. After
notice from the Underwriter to such party of the Underwriter's election to
assume the defense thereof, the Indemnified Party shall bear the fees and
expenses of any additional counsel retained by it, and the Underwriter will not
be liable to such party under this Agreement for any legal or other expenses
subsequently incurred by such party independently in connection with the defense
thereof other than reasonable costs of investigation.

           8.2(d). The Company agrees promptly to notify the Underwriter of the
commencement of any litigation or proceedings against it or any of its officers
or directors in connection with the issuance or sale of the Contracts or the
operation of each Account.

           8.3. Indemnification By the Fund

           8.3(a). The Fund agrees to indemnify and hold harmless the Company
and each of its directors and officers and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act (collectively, the
"Indemnified Parties" for purposes of this Section 8.3) against any and all
losses, claims, damages, liabilities (including amounts paid in settlement with
the written consent of the Fund) or litigation (including legal and other
expenses) to which the Indemnified Parties may become subject under any statute,
at common law or otherwise, insofar as such losses, claims, damages, liabilities
or expenses (or actions in respect thereof) or settlements result from the gross
negligence, bad faith or willful misconduct of the Trustees any member thereof,
are related to the operations of the Fund and:

                breach of this Agreement by the Fund;

as limited by and in accordance with the provisions of Sections 8.3(b) and
8.3(c) hereof.

           8.3(b). The Fund shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
to which an Indemnified Party would otherwise be subject by reason of such
Indemnified Party's willful misfeasance, bad faith, or gross negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of obligations and duties under this Agreement or to
the Company, the Fund, the Underwriter or each Account, whichever is applicable.

           8.3(c). The Fund shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified the Fund in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of

such claim shall net relieve the Fund from any liability which it may have to
the Indemnified Party against whom such action is brought otherwise than on

account of this indemnification provision. In case any such action is brought
against the Indemnified Parties, the Fund will be entitled to participate, at
its own expense, in the defense thereof. The Fund also shall be entitled to
assume the defense thereof, with counsel satisfactory to the party named in the
action. After notice from the Fund to such party of the Fund's election to
assume the defense thereof, the Indemnified Party shall bear the fees and
expenses of any additional counsel retained by it, and the Fund will not be

ARTICLE X. Termination

           10.1. This Agreement shall terminate:

                (a) at the option of any party upon one year advance written
                notice to the other parties; provided, however such notice shall
                not be given earlier than one year following the date of this
                Agreement; or

                (b) at the option of the Company to the extent that shares of
                Portfolios are not reasonably available to meet the requirements
                of the Contracts as determined by the Company, provided however,
                that such termination shall apply only to the Portfolio(s) not

                for such cause shall be furnished by the Company; or

                (c) at the option of the Fund in the event that formal

                the Fund shares, provided, however, that the Fund determines in
                its sole judgment exercised in good faith, that any such
                administrative proceedings will have a material adverse effect
                upon the ability of the Company to perform its obligations under
                this Agreement; or

                (d) at the option of the Company in the event that formal

adverse effect upon the ability of the Fund or Underwriter to perform its
obligations under this Agreement; or

(e) with respect to any Account, upon requisite vote of the Contract owners
having an interest in such Account (or any subaccount) to substitute the shares
of another investment company for the corresponding Portfolio shares of the Fund
in accordance with the terms of the Contracts for which those Portfolio shares
had been selected to serve as the underlying investment media. The Company will
give 30 days' prior written notice to the Fund of the date of any proposed vote
to replace the Fund's shares; or

(f) at the option of the Company, in the event any of the Fund's shares are not
registered, issued or sold in accordance with applicable state and/or federal
law or such law precludes the use of such shares as the underlying investment
media of the Contracts issued or to be issued by the Company; or

(g) at the option of the Company, if the Fund ceases to qualify as a Regulated
Investment Company under Subchapter M of the Code or under any successor or
similar provision, or if the Company reasonably believes that the Fund may fail
to so qualify; or 

(h) at the option of the Company, if the Fund fails to meet the diversification
requirements specified in Article VI hereof; or


                                      -29-
<PAGE>   30

(i) at the option of either the Fund or the Underwriter, if (1) the Fund or the
Underwriter, respectively, shall determine, in their sole judgment reasonably
exercised in good faith, that the Company has suffered a material adverse change
in its business or financial condition or is the subject of material adverse
publicity and such material adverse change or material adverse publicity will
have a material adverse impact upon the business and operations of either the
Fund or the Underwriter, (2) the Fund or the Underwriter shall notify the
Company in writing of such determination and its intent to terminate this
Agreement, and (3) after considering the actions taken by the Company and any

determination of the Fund or the Underwriter shall continue to apply on the
sixtieth (60th) day following the giving of such notice, which sixtieth day
shall be the effective date of termination; or

(j) at the option of the Company, if (1) the Company shall determine, in its
sole judgment reasonably exercised in good faith, that either the Fund or the
Underwriter has suffered a material adverse change in its business or financial
condition or is the subject of material adverse publicity and such material
adverse change or material adverse publicity will have a material adverse impact
upon the business and operations of the Company,

(2) the Company shall notify the Fund and the Underwriter in writing of such
determination and its intent to terminate the Agreement, and (3) after
considering the actions taken by the Fund and/or the Underwriter and any other

<PAGE>   31

                circumstances since the giving of such notice, such
                determination shall continue to apply on the sixtieth (60th) day
                following the giving of such notice, which sixtieth day shall be
                the effective date of termination; or

                (k) at the option of either the Fund or the Underwriter, if the
                Company gives the Fund and the Underwriter the written notice
                specified in Section 1.6(b) hereof and at the time such notice
                was given there was no notice of termination outstanding under
                any other provision of this Agreement; provided, however any
                termination under this Section 10.1(k) shall be effective forty
                five (45) days after the notice specified in Section 1.6(b) was
                given.

           10.2. It is understood and agreed that the right of any party hereto
to terminate this Agreement pursuant to Section 10.1(a) may be exercised for any
reason or for no reason.

           10.3. Notice Requirement.  No termination of this Agreement shall
be effective unless and until the party terminating this Agreement gives prior
written notice to all other parties to this Agreement of its intent to terminate
which notice shall set forth the basis for such termination. Furthermore,

                (a) In the event that any termination is based upon the
                provisions of Article VII, or the provision of Section 10.1(a),
                10.1(i), 10.1(j) or 10.1(k) of this Agreement, such prior 
                written notice shall be given in advance of the effective date 
                of termination as required by such provisions; and

                (b) in the event that any termination is based upon the
                provisions of Section 10.1(c) or 10.1(d) of this Agreement, such



                                      -31-
<PAGE>   32

                 prior written notice shall be given at least ninety (90) days
                 before the effective date of termination.

           10.4. Effect of Termination. Notwithstanding any termination of this
Agreement, the Fund and the Underwriter shall at the option of the Company,
continue to make available additional shares of the Fund pursuant to the terms
and conditions of this Agreement, for all Contracts in effect on the effective
date of termination of this Agreement (hereinafter referred to as "Existing
Contracts"). Specifically, without limitation, the owners of the Existing
Contracts shall be permitted to reallocate investments in the Fund, redeem
investments in the Fund and/or invest in the Fund upon the making of additional
purchase payments under the Existing Contracts. The parties agree that this
Section 10.4 shall not apply to any terminations under Article VII and the
effect of such Article VII terminations shall be governed by Article VII of this
Agreement.

           10.5. The Company shall not redeem Fund shares attributable to the
Contracts (as opposed to Fund shares attributable to the Company's assets held
in each Account) except (i) as necessary to implement Contract Owner initiated
transactions, or (ii) as required by state and/or federal laws or regulations or
judicial or other legal precedent of general application (hereinafter referred
to as a "Legally Required Redemption"). Upon request, the Company will promptly
furnish to the Fund and the Underwriter the opinion of counsel for the Company
(which counsel shall be reasonably satisfactory to the Fund and the Underwriter)
to the effect that any redemption pursuant to clause (ii) above is a Legally
Required Redemption. Furthermore, except in cases where permitted under the
terms of the Contracts, the Company shall not prevent Contract Owners from
allocating payments to a Portfolio that was otherwise available under the
Contracts without first giving the Fund or the Underwriter 90 days notice of its
intention to do so.

                             PROXY VOTING PROCEDURE



The following is a list of procedures and corresponding responsibilities for the
handling of proxies relating to the Fund by the Underwriter, the Fund and the
Company. The defined terms herein shall have the meanings assigned in the
Participation Agreement except that the term "Company" shall also include the
department or third party assigned by the Insurance Company to perform the steps
delineated below.


 1.   The number of proxy proposals is given to the Company by the Underwriter
      as early as possible before the date set by the Fund for the shareholder
      meeting (the "Record Date") to facilitate the establishment of tabulation
      procedures. At this time the Underwriter will inform the Company of the
      Record, Mailing and Meeting dates. This will be done verbally
      approximately two months before meeting.

 2.   Promptly after the Record Date, the Company will perform a "tape run", or
      other activity, which will generate the names, addresses and number of
      units/shares which are attributed to each contractowner/policyholder
      (the "Customer") as of the Record Date. Allowance should be made for
      account adjustments made after this date that could affect the status of
      the Customers' accounts as of the Record Date.


           Note:        The number of voting instruction cards is determined by
                        the activities described in Step #2. The Company will
                        use its best efforts to call in the number of Customers
                        to Fidelity, as soon as possible, but no later than two
                        weeks after the Record Date.


 3.   The Fund's Annual Report must be sent to each Customer by the Company
      either before or together with the Customers' receipt of a proxy
      statement. Underwriter will provide at least one copy of the last Annual
      Report to the Company.



                                      -38-
<PAGE>   39


            d.    "urge buckslip" - optional, but recommended. (This is a
                  small, single sheet of paper that requests Customers to vote
                  as quickly as possible and that their vote is important. One
                  copy will be supplied by the Fund.)

            e.    cover letter - optional, supplied by Company and reviewed and
                  approved in advance by Fidelity Legal.

8.     The above contents should be received by the Company approximately 3-5
       business days before mail date. Individual in charge at Company reviews
       and approves the contents of the mailing package to ensure correctness
       and completeness. Copy of this approval sent to Fidelity Legal.

9.     Package mailed by the Company.

       *    The Fund must allow at least a 15-day solicitation time to the
            Company as the shareowner. (A 5-week period is recommended, but not
            necessary, to receive a proper response percentage.) Solicitation
            time is calculated as days from (but not including) the meeting,
            counting backwards.

       **   If the Customers were actually the shareholders, at least 50% of the
            outstanding shares must be represented and 66 2/3% of that 50% must
            have voted affirmatively on the proposals to have an effective vote.
            However, since the Company is the shareholder, the Customers' votes
            will (except in certain limited circumstances) be used to dictate 
            how the Company will vote.

10.    Collection and tabulation of Cards begins. Tabulation usually takes place
       in another department or another vendor depending on process used. An
       often used procedure is to sort Cards on arrival into vote categories of
       all yes, no, or mixed replies, and to begin data entry.

            *     Postmarks are not generally needed. A need for postmark
                  information would be due to an insurance company's internal
                  procedure and has not been required by Fidelity in the past.




                                      -40-
<PAGE>   40

18.    Vote is verified by the Company and is sent to Fidelity Legal.

17.    Company then votes its proxy in accordance with the votes received from
       the Customers the morning of the meeting (except in limited circumstances
       as may be otherwise required by law). A letter documenting the Company's
       vote is supplied by Fidelity Legal and is sent to officer of company for
       his signature. This letter is normal sent after the meeting has taken
       place.

18.    The Company will be required to box and archive the Cards received from
       the Customers. In the event that any vote is challenged or if otherwise
       necessary for legal, regulatory, or accounting purposes, Fidelity will be
       permitted reasonable access to such Cards.

19.    All approvals and "signing-off" may be done orally, but must always be
       followed up in writing.

20.    During tabulation procedures, the Fund and Company determine if a
       resolicitation is required and what form that resolicitation should take,
       whether it should be by a mailing, or by recorded telephone line. A
       resolicitation is considered when the vote response is slow and it
       appears that not enough votes would be received by the meeting date. The
       meeting could be adjourned to leave enough time for the resolicitation.

       A determination is made by the Company and the Fund to find the most cost
       effective candidates for resolicitation. These are Customers who have not
       yet voted, but whose balances are large enough to bring in the required
       vote with minimal costs.

          a.  By mail: Fidelity Legal amends the voting instruction cards, if
              necessary, and writes a resolicitation letter. The Fund supplies
              these to the Company. The Company generates a mailing list etc.,
              as per step 2 onward. 
            
          b.  By phone: Rarely used. This must be done on a recorded line.
              Fidelity Legal and the Fund will supply the necessary procedures
              and script if a phone resolicitation were to be required.

net asset value next computed after receipt by the Fund or its designee of the
order for the shares of the Fund. For purposes of this Section 1.1, the Company

        1.2. The Fund agrees to make its shares available indefinitely for
purchase at the applicable net asset value per share by the Company and its
Accounts on those days on which the Fund calculates its net asset value pursuant
to rules of the Securities and Exchange Commission and the Fund shall use
reasonable efforts to calculate such net asset value on each day which the New
York Stock Exchange is open for trading. Notwithstanding the foregoing, the
Board of Trustees of the Fund (hereinafter the "Trustees") may refuse to sell
shares of any Portfolio to any person, or suspend or terminate the offering of
shares of any Portfolio if such action is required by law or by regulatory
authorities having jurisdiction or is, in the sole discretion of the Trustees
acting in good faith and in light of their fiduciary duties under federal and
any applicable state laws, necessary in the best interests of the shareholders
of such Portfolio.

        1.3. The Fund and the Underwriter agree that shares of the Fund will
be sold only to Participating Insurance Companies and their separate accounts.
No shares of any Portfolio will be sold to the general public.

        1.4. The Fund and the Underwriter will not sell Fund shares to any
insurance company or separate account unless an agreement containing provisions
substantially the same as Articles I, III, V, VII and Sections 2.5 and 2.12 of
Article II of this Agreement is in effect to govern such sales.

        1.5. The Fund agrees to redeem for cash, on the Company's request,
any full or fractional shares of the Fund held by the Company, executing such
requests on a daily basis at the net asset value next computed after receipt by
the Fund or its designee of the request for redemption. For purposes of this
Section 1.5, the Company shall be the

Portfolio offered by the then current prospectus of the Fund and in accordance
with the provisions of such prospectus. The Company agrees that all net amounts
available under the variable life insurance contracts with the form number(s)
which are listed on Schedule A attached hereto and incorporated herein by this
reference, as such Schedule A may be amended from time to time hereafter by
mutual written agreement of all the parties hereto, (the "Contracts") shall be
invested in the Fund, in such other Funds advised by the Adviser as may be
mutually agreed to in writing by the parties hereto, or in the Company's general
account, provided that such amounts may also be invested in an investment
company other than the Fund if (a) such other investment company, or series
thereof, has investment objectives or policies that are substantially different
from the investment objectives and policies of all the Portfolios of the Fund;
or (b) the Company gives the Fund and the Underwriter 45 days written notice of
its intention to make such other investment company available as a funding
vehicle for the Contracts; or (c) such other investment company was available as
a funding vehicle for the Contracts prior to the date of this Agreement and the
Company so informs the Fund and Underwriter prior to their signing this
Agreement; or (d) the Fund or Underwriter consents to the use of such other
investment company.

        1.7.    The Company shall pay for Fund shares on the next Business Day
after an order to purchase Fund shares is made in accordance with the

                                      -5-


<PAGE>   6
provisions of Section 1.1 hereof. Payment shall be in federal funds transmitted
by wire. For purpose of Sections 2.10 and 2.11, upon receipt by the Fund of the
federal funds so wired, such funds shall cease to be the responsibility of the
Company and shall become the responsibility of the Fund.

        1.8.    Issuance and transfer of the Fund's shares will be by book entry
only. Stock certificates will not be issued to the Company or the Accounts.
Shares ordered from the Fund will be recorded in an appropriate title for each
Account or the appropriate subaccount of each Account.

        1.9     The Fund shall furnish same day notice (by wire or telephone,
followed by written confirmation) to the Company of any income, dividends or
capital gain distributions payable on the Funds' shares. The Company hereby
elects to receive all such income dividends and capital gain distributions as
are payable on the Portfolio shares in additional shares of that Portfolio. The
Company reserves the right to revoke this election and to receive all such
income dividends and capital gain distributions in cash. The Fund shall notify
the Company of the number of shares so issued as payment of such dividends and
distributions.

        1.10.   The Fund shall make the net asset value per share for each
Portfolio available to the Company on a daily basis as soon as reasonably
practical after the net asset value per share is calculated and shall use its
best efforts to make such net asset value per share available by 7 p.m. Boston
time.

the affected contract owners the option of making such a change; and (2),
establishing a new registered management investment company or managed separate
account.          

        7.4. If a material irreconcilable conflict arises because of a decision
by the Company to disregard contract owner voting instructions and that decision
represents a minority position or would preclude a majority vote, the Company
may be required, at the Fund's election, to withdraw each Account's investment
in the Fund and terminate this


                                      -17-


<PAGE>   18
Agreement; provided, however that such withdrawal and termination shall be
limited to the extent required by the foregoing material irreconcilable conflict
as determined by a majority of the disinterested members of the Board. Any such
withdrawal and termination must take place within six (6) months after the Fund
gives written notice that this provision is being implemented, and until the end
of that six month period the Underwriter and Fund shall continue to accept and
implement orders by the Company for the purchase (and redemption) of shares of
the Fund.

        7.5.    If a material irreconcilable conflict arises because a
particular state insurance regulator's decision applicable to the Company
conflicts with the majority of other state regulators, then the Company will
withdraw each Account's investment in the Fund and terminate this Agreement
within six months after the Board informs the Company in writing that it has
determined that such decision has created an irreconcilable material conflict;
provided, however, that such withdrawal and termination shall be limited to the
extent required by the foregoing material irreconcilable conflict as determined
by a majority of the disinterested members of the Board. Until the end of the
foregoing six month period, the Underwriter and Fund shall continue to accept
and implement orders by the Company for the purchase (and redemption) of shares
of the Fund.

        7.6.    For purposes of Sections 7.3 through 7.6 of this Agreement, a
majority of the disinterested members of the Board shall determine whether any
proposed action adequately remedies any irreconcilable material conflict, but
in no event will the Fund be required to establish a new funding medium for the
Contracts. The Company shall not be required by Section 7.3 to establish a new
funding medium for the Contracts if an

                                      -18-


<PAGE>   19

offer to do so has been declined by vote of a majority of Contract owners
materially adversely affected by the irreconcilable material conflict. In the
event that the Board determines that any proposed action does not adequately
remedy any irreconcilable material conflict, then the Company will withdraw
each Account's investment in the Fund and terminate this Agreement within six
(6) months after the Board informs the Company in writing of the foregoing
determination, provided, however, that such withdrawal and termination shall be
limited to the extent required by any such material irreconcilable conflict as
determined by a majority of the disinterested members of the Board.

        7.7.    If and to the extent that Rule 6e-2 and Rule 6e-3(T) are
amended, or Rule 6e-3 is adopted, to provide exemptive relief from any provision
of the Act or the rules promulgated thereunder with respect to mixed or shared
funding (as defined in the Shared Funding Exemptive Order) on terms and
conditions materially different from those contained in the Shared Funding
Exemptive Order, then (a) the Fund and/or the Participating Insurance Companies,
as appropriate, shall take such steps as may be necessary to comply with Rules
6e-2 and 6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such
rules are applicable; and (b) Sections 3.4, 3.5, 7.1, 7.2, 7.3, 7.4, and 7.5 of
this Agreement shall continue in effect only to the extent that terms and
conditions substantially identical to such Sections are contained in such
Rule(s) as so amended or adopted.

        in the Registration Statement or prospectus for the Contracts or in the

        (other than statements or representations contained in the Registration
        Statement, prospectus or sales literature of the Fund not supplied by
        the Company, or persons under its control) or wrongful conduct of the
        Company or persons under its control, with respect to the sale or
        distribution of the Contracts or Fund Shares; or

        (iii) arise out of any untrue statement or alleged untrue statement of a

liabilities or litigation to which an Indemnified Party would otherwise be
subject by reason of such Indemnified Party's willful misfeasance, bad faith, or
gross negligence in the performance of such Indemnified Party's duties or by
reason of such Indemnified Party's reckless disregard of obligations or duties
under this Agreement or to the Fund, whichever is applicable.

        8.1(c). The Company shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified the Company in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify the Company of any
such claim shall not relieve the Company from any liability which it may have to
the Indemnified Party against whom such action is brought otherwise than on
account of this indemnification provision. In case any such action is brought

(collectively, the "Indemnified Parties" for purposes of this Section 8.2)
against any and all losses, claims, damages, liabilities (including amounts paid

against the Indemnified Parties, the Underwriter will be entitled to
participate, at its own expense, in the defense thereof. The Underwriter

retained by it, and the Underwriter will not be liable to such party under this
Agreement for any legal or other expenses subsequently incurred by such party
independently in connection with the defense thereof other than reasonable costs
of investigation.

          adverse publicity and such material adverse change or material adverse
          publicity will have a material adverse impact upon the business and

          written notice shall be given in advance of the effective date of
          termination as required by such provisions; and

          (b) in the event that any termination is based upon the provisions of

Agreement, the Fund and the Underwriter shall at the option of the Company,
continue to make available additional shares of the Fund pursuant to the terms
and conditions of this Agreement, for all Contracts in effect on the effective
date of termination of this Agreement (hereinafter referred to as "Existing
Contracts"). Specifically, without limitation, the owners of the Existing
Contracts shall be permitted to reallocate investments in the Fund, redeem
investments in the Fund and/or invest in the Fund upon the making of additional
purchase payments under the Existing Contracts. The parties agree that this

effect of such Article VII terminations shall be governed by Article VII of this
Agreement.

        10.5. The Company shall not redeem Fund shares attributable to the
Contracts (as opposed to Fund shares attributable to the Company's assets held
in each Amount) except (i) as necessary to implement Contract Owner initiated
transactions, or (ii) as required by state and/or federal laws or regulations or
judicial or other legal precedent of general application (hereinafter referred
to as a "Legally Required Redemption").

Upon request, the Company will promptly furnish to the Fund and the Underwriter
the opinion of counsel for the Company (which counsel shall be reasonably
satisfactory to the Fund and the Underwriter) to the effect that any redemption
pursuant to clause (ii) above is a Legally Required Redemption. Furthermore,
except in cases where permitted under the terms of the Contracts, the Company
shall not prevent Contract Owners from allocating payments to a Portfolio that
was otherwise available under the Contracts without first giving the Fund or the
Underwriter 90 days notice of its intention to do so.

RE: Variable Annuity Registration Statement

Ladies and Gentlemen:

         With reference to the Post-Effective Amendment No. 2 to the
Registration Statement on Form N-4 as amended, filed by National Life Insurance
Company and National Variable Annuity Account II with the Securities and
Exchange Commission covering individual variable annuity contracts, I have
examined such documents and such laws as I considered necessary and appropriate
and on the basis of such examination, it is my opinion that:

         1.  National Life Insurance Company is duly organized and validly
existing under the laws of the state of Vermont, and has been duly authorized
to issue individual variable annuity contracts by the Department of Insurance
of the State of Vermont.

         2.  National Variable Annuity Account II is a duly authorized and
existing separate account established pursuant to the provisions of Title 8,
Vermont Statutes Annotated, sections 3855 to 3859.

         3.  The individual variable annuity contracts, when issued as
contemplated by said Form N-4 Registration Statement, will constitute legal,
validly issued and binding obligations of National Life Insurance Company.

         I hereby consent to the filing of this opinion as an Exhibit to said
Post-Effective Amendment No. 2 to the  Form N-4 Registration Statement and to
the use of my name under the caption "Legal Matters" in the Registration
Statement.

                                        Sincerely,



                                        Michele S. Gatto
                                        Senior Vice President
