                                    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 14. The initial Premium Payment must be at least
$5,000 for Non-Qualified Contracts, and at least $1500 for Qualified Contracts.
We may at our discretion permit initial Premium Payments lower than these
minimums.

CAN I MAKE ADDITIONAL PREMIUM PAYMENTS?


      You may make additional Premium Payments at any time (except for Contracts
purchased in Oregon and Massachusetts - see page 15), 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 Owner (or Annuitant if the owner
is not a natural person) may not exceed $1,000,000 without our prior consent
(see "Premium Payments," page 15).


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, you may revoke the Contract during the free look
period and we will refund Premium Payments.


WHAT IS THE PURPOSE OF THE VARIABLE ACCOUNT?

      The Variable Account is a separate investment account that consists of 27
Subaccounts. 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 9-14).

      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 your Contract may
be more or less than the premiums paid.

                                       1
<PAGE>   10

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", page 31).

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 17).

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 less all outstanding loans and accrued
interest). The amount paid will be reduced by premium tax charges, if any. For
more information, see "Death of Owner," page 19.

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 20).

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 26). A
Withdrawal or a surrender may result in federal income tax, including a federal
penalty tax (see "Federal Income Tax Considerations," page 33).

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 22).

      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 23).

      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 22).

      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 22).

                                       2
<PAGE>   11

      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
Optional Enhanced Death Benefit Rider," page 24).

      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 24).

      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 5, and the accompanying Fund
prospectuses).

ARE THERE ANY OTHER CONTRACT PROVISIONS?

      For information concerning other important Contract provisions, see
"Contract Rights and Privileges," page 24, 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 33.

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 24.

(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, New Jersey and Washington 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 22).

(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 33.

(5) 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

*For purposes of computing the Annual Contract Fee, the Annual Contract Fee has
been converted into a per-dollar per-day charge. The per-dollar per-day charge
has been calculated by taking the total Annual Contract Fees received during
1999 and dividing by the average assets in the Variable Account. This works out
to 0.6% per annum. The Annual Contract Fee is waived for Contracts with
Contract Values of $50,000 or more.


**The Contract may not be annuitized in the first two years from the Date of
Issue.

*For purposes of computing the Annual Contract Fee, the Annual Contract Fee has
been converted into a per-dollar per-day charge. The per-dollar per-day charge
has been calculated by taking the total Annual Contract Fees received during
1999 and dividing by the average assets in the Variable Account. This works out
to 0.06% per annum. The Annual Contract Fee is waived for Contracts with
Contract Values of $50,000 or more.


**The Contract may not be annuitized in the first two years from the Date of
Issue.

      The purpose of the Summary of Contract Expenses and Example is to assist
you in understanding the various costs and expenses that will be borne directly
or indirectly when investing in the Contract. The expenses of the Variable
Account as well as those of the underlying Funds are reflected in the Example.
For more complete descriptions of the expenses of the Variable Account, see
"Charges and Deductions", page 21. For more complete information regarding
expenses paid out of the assets of the underlying Funds, see the underlying Fund
prospectuses. Deductions for premium taxes may also apply but are not reflected
in the Example shown above (see "Premium Taxes", page 24). Certain states impose
a premium tax, currently ranging up to 3.5%.

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.

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

by some investment advisers or distributors than other advisers or

provided with respect to the Fund and its availablity through the Contract. The

These arrangements may change from time to time, and may include more Funds in
the future.


        Conflicts of Interest. 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 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. At our discretion, we may issue Contracts at ages higher than age
85.

        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.


      A tax-favored arrangement, including an IRA and a Roth IRA, should
carefully consider the costs and benefits of the Contract (such as
annuitization benefits) before purchasing a Contract since the tax-favored
arrangement itself provides for tax-sheltered growth.

PREMIUM PAYMENTS

        The Initial Premium Payment. The initial Premium Payment must be at

lower than these minimums. For Contracts purchased in South Carolina, the

        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. Subsequent Premium Payments to the Variable
Account will purchase Accumulation Units at the price next computed for the
appropriate Subaccount after we receive the additional Premium Payment. For
Contracts purchased in the States of Oregon and Massachusetts, 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 Owner (or Annuitant if the owner is not a natural person) 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 28).

        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.

        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.




        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.


                                       15

<PAGE>   24

        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 28. 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 27.


        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 unloaned 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 (25%
in New York). 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 23.

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 value of an
Accumulation Unit 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 value of an Accumulation
Unit 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.


                                       16
<PAGE>   25



        -  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, minus any
        outstanding loans on the Contract and accrued interest on such loans.

        When charges or deductions are made against the Contract Value, we
deduct an appropriate number of Accumulation Units from the Subaccounts and an
appropriate amount from the Fixed Account in the same proportion that the your
interest in the Subaccounts and the unloaned value in the 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. The Maturity Date is the date on which annuity payments
are scheduled to begin. You select the Maturity Date on the application. The
earliest Maturity Date must be at least 2 years after the Date of Issue, unless
otherwise approved (10 years after the Date of Issue in the States of Oregon
and Massachusetts). 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. You may elect
a single payment equal to the cash Surrender Value on the Maturity Date, rather
than annuity payments.

        If you request in writing (see "Ownership Provisions", page 20), 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 the Contract
Value in the Fixed Account (less any premium tax previously unpaid) to provide
a Fixed Annuity payment.

        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 with 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.

<PAGE>   26

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 on his or her birthday nearest the Annuitization Date, 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 payment to payment; 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.

        Once payments have begun, future payments will not reflect any changes
 in mortality experience.

        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 16).

        Assumed Investment Rate. A 3.5% Assumed Investment Rate is built into
the Annuity Tables contained in the Contracts. We may make assumed investment
rates available at rates other than 3.5%. 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, as measured by the Net Investment Factor, is at a
constant 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 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 using the age of the Chosen
Human Being on his or her nearest birthday, and the sex of the Chosen Human
Being, if applicable. The applicable Annuity Table will be based on our
expectation of investment earnings, expenses and mortality (if payments depend
on whether the Chosen Human Being is alive) on the Annuitization Date. The
applicable Annuity Table will provide a periodic Fixed Annuity payment at least
as great as the guarantee described in your Contract.

        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.

<PAGE>   27



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 a 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.

        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.


        Qualified Contracts (except Roth IRA's before the Owner's death) 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. A surrender is
subject to any applicable Contingent Deferred Sales Charge at the time of the
surrender.

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, minus all
Withdrawals (including any CDSC deducted in connection with such Withdrawals),
and minus any outstanding loans on the Contract and accrued interest, and

in each case  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.

        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

                                       19

<PAGE>   28

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, 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.

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.


                                       20

<PAGE>   29

        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
33). 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 26. 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;

                                       21

<PAGE>   30


     (3) the risk that more Owners than expected will qualify for and exercise
         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. We may also realize a
profit on one or more of these charges. We may use any profits for any corporate
purpose, including sales expenses.


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 may pay a commission up to 6.5% (7.0% during certain promotional
periods) for the sale of a Contract; however, 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, and last from earnings on Net
Premium Payments. 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>

        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

                                       22

<PAGE>   31

an amount not exceeding the annual CDSC-free Withdrawal amount (see "Available
Automated Fund Management Features-Systematic Withdrawals", page 30), or by
making a Withdrawal which is part of a series of substantially equal periodic
payments over the life of the Owner or the joint lives of the Owner and his or
her spouse, to which section 72(t)(2)(A)(iv) of the Code applies. You may be
subject to a tax penalty if you take Withdrawals prior to age 59 1/2 (see
"Federal Income Tax Considerations", page 33). In New Jersey and Washington,
the CDSC-free provision will apply to full surrenders and Withdrawals 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 and less any outstanding loan and accrued interest, as of
        the last Contract Anniversary.

        We will waive the CDSC if the Owner dies or if the Owner annuitizes.
However, if the Owner elects a settlement under Payment Option 1, and
subsequently surrenders the Contract prior to seven years after the date of the
last Premium Payment, the surrender will be subject to a CDSC.

        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. This waiver is
not available in the States of New Jersey and New York.

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 unloaned portion of 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 16. 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. We would not
anticipate making a profit on any future transfer charge.


     If we impose a transfer charge, we will deduct it 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


                                       23

<PAGE>   32


Rebalancing features, transfers resulting from loans, 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 33. 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 unloaned portion of 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 5.

        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 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. In order to revoke the
Contract, if it has not been received, written notice must be mailed or
delivered to the Home Office.

        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.

LOAN PRIVILEGE - TAX SHELTERED ANNUITIES


        Subject to approval in your state, if you own a section 403(b)
Tax-Sheltered Annuity Contract, a loan provision will be available on your
Contract. Loans will be subject to the terms of the Contract and the Code.



        If a loan provision is included in your Tax-Sheltered Annuity Contract,
loans will be available anytime prior to the Annuitization Date. You will be
able to borrow a minimum of $1500 (we may permit lower amounts). The maximum
loan balance which may be outstanding at any time on your Contract is 90% of the
sum of Contract Value, outstanding loans and accrued interest on loans minus the
CDSC that would apply if you surrended your Contract. In no event may the
aggregate amount borrowed from all your Tax-Sheltered Annuities or other
Qualified Contracts, including this Contract, exceed the lesser of:



      (a)    50% of the combined nonforfeitable account balances of all your
             Tax-Sheltered Annuities or other Qualified Contracts (or in the
             case of non-ERISA Plans, $10,000 if greater); and
      (b)    $50,000



The $50,000 limit will be reduced by the excess (if any) of the highest loan
balances owed during the prior one-year period over the loan balance on the date
the loan is made. The highest loan balance owed during the prior one-year period
may be more than the amount outstanding at the time of the loan, if an interest
payment or prinicpal repayment has been made.



        All loans will be made from the Collateral Fixed Account. When a loan is
taken an amount equal to the principal amount of the loan will be transferred to
the Collateral Fixed Account. We will transfer to the Collateral Fixed Account
an amount equaling the loan from the Subaccounts of the Variable Account and
unloaned portion of the Fixed Account in the same proportion that such amounts
bear to the total Contract Value. No CDSC is deducted at the time of the loan or
on any transfers to the Collateral Fixed Account.



        Until the loan is repaid in full, that portion of the Collateral Fixed
Account equal to the outstanding loan balance shall be credited with interest at
an annual rate we declare from time to time, but will never be less than an
annual rate of 3.0%. On each Contract Anniversary and on each date that a loan
repayment is received, any amount of interest credited on the Collateral Fixed
Account will be allocated among the Fixed Account and the Subaccounts of the
Variable Account in accordance with the allocation of Net Premium Payments then
in effect.



        Loans must be repaid in substantially level payments, not less
frequently than quarterly, within five years. Loans used to purchase your
principal residence must be repaid within 20 years. During the loan term, the
outstanding balance of the loan will continue to accrue interest at annual
rates specified in the loan agreement or an amendment to the loan agreement.


        -  the Moody's Corporate Bond Yield Average - Monthly Average
           Corporates, as published by Moody's Investors Service, Inc., or its
           successor, (or if that average is no longer published, a
           substantially similar average), for the calendar month ending two
           months before the date the rate is determined; or
        -   4%.


        The loan interest rate is subject to change on each Contract
Anniversary. If the loan interest rate changes, we will send you a notice of the
new loan interest rate and new level payment amount. We must reduce the loan
interest if on a Contract Anniversary the maximum loan interest rate is lower






                                       25

<PAGE>   34


than the interest rate for the previous Contract Year by 0.50% or more. We may
increase the loan interest rate if the maximum loan interest rate is at least
0.50% higher than the loan interest rate for the previous Contract Year. The
loan interest rate we charge will be equal to or less than the maximum loan
interest rate at the time it is determined, and will never be higher than 15%.



        Twenty days prior to the due date of each loan repayment, as set forth
in the loan agreement or an amendment to the loan agreement, we will send you a
notice of the amount due. Corresponding to the due date of each loan repayment,
we will establish a "billing window" defined as the period beginning on the date
that we mail the repayment notice (20 days prior to the payment due date) and
extending 31 days after the due date.



        Loan repayments received within the billing window that are sufficient
to satisfy the amount due will be applied to the Contract as interest and
repayment of principal. The amounts of principal and interest set forth in the
loan agreement or an amendment to the loan agreement, are the amounts if all
loan repayments are made exactly on the due date. The actual amount of a
repayment allocated to interest will be determined based on the actual date the
repayment is received, the amount of the outstanding loan, and the number of
days since the last repayment date. The amount of principal will be the
repayment amount minus the interest. The loan principal repayment will, on the
date it is received, be allocated among the Fixed Account and Subaccounts of the
Variable Account in accordance with the allocation of Net Premium Payments then
in effect.



         Loan repayments received outside of the billing window will be
processed as a repayment of principal only. Only repayments received within the
billing window may satisfy the amount due. If a payment received within the
billing window is less than the amount due, it will be returned to you.



         If a loan repayment that is sufficient to satisfy the amount due is not
made within the billing window, then the entire balance of the loan will be
considered in default. This amount may be taxable to the borrower, and may be
subject to the early withdrawal tax penalty. If you are not eligible to take a
distribution pursuant to the Contract or plan provisions, the deemed
distribution will be reportable for tax purposes, but will not be offset against
the Contract Value until such time as a distribution may be made. On each
Contract Anniversary, while a loan is in default, interest accrued on loans will
be added to the outstanding loans.



        If you surrender your Contract while a loan is outstanding, you will
receive the Cash Surrender Value, which is reduced to reflect the loan
outstanding plus accrued interest. If the Owner/Annuitant dies while the loan
is outstanding, the Death Benefit will also be reduced to reflect the amount of
the loan outstanding plus accrued interest. If annuity payments start while the
loan is outstanding, the Contract Value will be reduced by the amount of the
outstanding loan plus accrued interest. Until the loan is repaid, we may
restrict any transfer of the Contract which would otherwise qualify as a
transfer as permitted in the Code.






        Loans may also be subject to additional limitations or restrictions
under the terms of the employer's plan. Loans permitted under this Contract may
still be taxable in whole or part if the participant has additional loans from
other plans or contracts. We will calculate the maximum nontaxable loan based on
the information provided by the participant or the employer. In addition, if
the section 403(b) Tax-Sheltered Annuity Contract is subject to the Employee
Retirement Income Security Act of 1974 ("ERISA"), a loan will be treated as a
"prohibited transaction" subject to certain penalties unless additional ERISA
requirements are satisfied. You should seek competent legal advice before
requesting a loan.



        If a loan is outstanding, all payments received from you will be
considered loan repayments. Any payments received from your employer will be
considered premium payments. We reserve the right to modify the terms or
procedures associated with the loan privilege in the event of a change in the
laws or regulations relating to the treatment of loans. We also reserve the
right to assess a loan processing fee. IRA's, Non-Qualified Contracts and
Qualified Contracts other than section 403(b) Tax-Sheltered Annuity Contracts
are not eligible for loans.


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. "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 22), any outstanding loan and accrued
interest, and, in certain states, a premium tax charge (see "Premium Taxes",
page 24). 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.



                                       26

<PAGE>   35



        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, except where the Withdrawal is part of
an automated process of paying investment advisory fees to the Owner's
investment advisor. 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 New Jersey and Washington) 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 22. However, see "Available
Automated Fund Management Features-Systematic Withdrawals" page 30, for
information on a limited means of making systematic Withdrawals in the first
year free of the CDSC. Another limited way to make a Withdrawal in the first
year without paying a CDSC is to make a Withdrawal which is part of a series of
substantially equal periodic payments made for the life of the Owner or the
joint lives of the Owner and his or her spouse, under section 72(t)(2)(a)(iv)
of the Code. 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. If you provide specific
instructions, amounts must be deducted first from the Variable Account and may
only be deducted from the unloaned portion of 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 unloaned
portion of 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 CDSC 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 unloaned
portion of 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 33.

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,

        (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.

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, Withdrawal or loan
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 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 or make changes in
dollar costs averaging or portfolio rebalancing, and in the case of section
403(b) Tax Sheltered Annuities, take loans up to $10,000, 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





                                       28

<PAGE>   37

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 dollar cost averaging method of investment is
designed to reduce the risk of making purchases only when the price of units is
high. The periodic investment of the same amount will result in higher numbers
of units being purchased when unit prices are lower and lower numbers of units
being purchased when unit prices are higher. This technique will not 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.


     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

                                       29

<PAGE>   38

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. Portfolio
rebalancing does not guarantee a profit or protect against a loss.


        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 unloaned portion of 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 unloaned portion of 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 22. 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 10% CDSC-free Withdrawal provision applies in New
Jersey and Washington see "Contingent Deferred Sales Charge," page 22). 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 which is not held in a
Collateral Fixed Account is guaranteed to accumulate at a minimum effective
annual interest rate of 3.0%. We may credit the Contract Value in the unloaned
portion of 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 unloaned portion of 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 unloaned portion of 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.

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

ENHANCED FIXED ACCOUNT

      During special promotional periods (the "offer period"), we may make
available to the Contracts a special Fixed Account Option, called the "Enhanced
Fixed Account". The Enhanced Fixed Account, when available, allows you to move
value into the Variable Account on a gradual and systematic basis,


                                       31

<PAGE>   40


while earning interest at a higher fixed rate that that otherwise offered on
the Fixed Account on your value while it awaits transfer into the Variable
Account.

      During an offer period (which will be from time to time at our
discretion), the Enhanced Fixed Account will be available to new and existing
Contract Owners who make a one-time new Premium Payment of at least a minimum
dollar amount we specify at the time of the offer. Contract Value in the
Enhanced Fixed Account will accumulate at an effective annual interest rate in
excess of the current rates then being credited to Contract Value in the Fixed
Account. We will declare the interest rate for the Enhanced Fixed Account at
the time of the offer in our discretion, and this interest rate will apply for
the entire offer period. When we set an offer period, we will announce all the
terms of the Enhanced Fixed Account, and post this information on our web site
at www.nlv.com.

      We will require that the Contract Value in the Enhanced Fixed Account be
systematically transferred on a monthly basis from the Enhanced Fixed Account
to the Subaccounts. The required monthly transfer amount will be a percentage
of the Premium Payment allocated to the Enhanced Fixed Account. We will declare
this percentage at the time of the offer, in our discretion. Each month on the
Monthly Contract Date, the monthly transfer amount will be transferred from the
Enhanced Fixed Account to the Subaccounts and in the percentage amounts
selected by the Owner (other than the Money Market Subaccount), until the
Contract Value in the Enhanced Fixed Account is exhausted.

      The Enhanced Fixed Account will be part of the Fixed Account described
above.

      Transfers into the Enhanced Fixed Account will not be allowed. The Owner
may transfer Contract Value out of the Enhanced Fixed Account at any time, by
making a transfer request. If the entire Contract Value in the Enhanced Fixed
Account is transferred out, the program ends. If less than the entire Contract
Value in the Enhanced Fixed Account is transferred out, the scheduled monthly
transfers will continue until the Enhanced Fixed Account is exhausted.

      Withdrawals from the Enhanced Fixed Account will be allowed, in the same
manner as for other Withdrawals, but will be subject to any applicable CDSC.

      For Contracts utilizing the Enhanced Fixed Account, National Life
reserves the right to reduce the number of different Subaccounts, other than
the Money Market Subaccount, that may be used by the Contract over its entire
lifetime from 16 to 15. There is no charge for participating in an offer
period.

      This program is not available simultaneously with Dollar Cost Averaging,
Portfolio Rebalancing or Systematic Withdrawals. If you elect Systematic
Withdrawals while you have Contract Value in the Enhanced Fixed Account, your
Contract Value in the Enhanced Fixed Account will immediately be transferred to
your selected Subaccounts.

      During the offer period we may permit, in our discretion, additional
Premium Payments on the same Contract to be allocated to the Enhanced Fixed
Account. If we do so, we will add a declared percentage of the new Premium
Payment to the original monthly transfer amount, the same instructions for
allocating to the Subaccounts will apply, and the program will continue to
operate until the Contract Value in the Enhanced Fixed Account is exhausted.

      We may need to refund Premium Payments intended for the Enhanced Fixed
Account if they are less than the minimum required, if they are received after
the end of the offer period, or if, for any other reason, the written
instructions of the Owner cannot be carried out. We may hold these Premium
Payments for up to 20 days before refunding them. Any amounts refunded will be
credited with interest at 5%.

      This program will not be available in the State of Washington.

                     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
is not available in Texas. 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, or the Annuitant if the Owner is not a
natural person) 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
            (including any CDSC deducted in connection with such Withdrawals)
            and less any outstanding loan and accrued interest, and



        (c) 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,minus any Withdrawals (including any CDSC
        deducted in connection with such Withdrawals), and minus any loan taken
        and accrued interest thereon, in each case 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
24).

        If you (or the first of Joint Owners, or the Annuitant if the Owner is
not a natural person) 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, and any outstanding loan on the Contract and accrued interest on
such loan.


        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 24.

        We distribute the Enhanced Death Benefit in the same manner as the
normal Death Benefit. See "Death of Owner", page 19.

                       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




                                       33

<PAGE>   42


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.

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.



                                       34

<PAGE>   43



        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 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.

        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



                                       35

<PAGE>   44


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. 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 tax-sheltered annuity.
Because the Death Benefit may exceed this limitation, employers using the
Contract in connection with such plans should consult their tax adviser.



        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. For non-governmental Section 457
plans, all such investments, 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, Section
403(a) annuities and Section 403(b) 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.


                                       36

<PAGE>   45



                                 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 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 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

                                       37

<PAGE>   46

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, the
        optional Enhanced Death Benefit Rider charge of 0.20% were deducted.
        For purposes of computing the Annual Contract Fee, the Annual Contract
        Fee has been converted into a per-dollar per-day charge. The per-dollar
        per-day charge has been converted based on the actual average
        Accumulated Value of the Contracts as of December 31, 1999. The charge
        works out to 0.04% per annum.



               Based on the method of calculation described above, the
        Standardized Average Annual Total Returns for the Subaccounts for the
        periods ending December 31, 1999 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 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. 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. For purposes of
        computing the Annual Contract Fee, the Annual Contract Fee has been
        converted into a per-dollar per-day charge. The per-dollar per-day
        charge has been converted based on the actual average Accumulated Value
        of the Contracts as of December 31, 1999. The charge works out to 0.04%
        per annum.



               Based on the method of calculation described above, the
        Nonstandardized Subaccount Average Annual Total Returns for the
        Subaccounts for the period ending December 31, 1999, were:

               Adjusted Historic Average Annual Total Return. In addition,
        historic performance data may be presented for the Funds since their
        inception, reduced by some or all of the fees and charges under the
        Contracts. Such adjusted historic Fund performance includes data that
        precedes the inception date of the Subaccounts. This data is designed
        to show performance that would have resulted if the Contract had been
        in existence during that time. Adjusted historic Fund performance data
        will be shown only if standard performance data for the Subaccounts is
        also shown.

               The charts below show adjusted historic average annual total
        return for the Funds for the indicated periods. For the purposes of
        calculating Adjusted Historic Fund 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 (if so indicated) the
        applicable CDSC and/or the optional Enhanced Death Benefit Rider Charge
        of 0.20% were deducted. For purposes of computing the Annual Contract
        Fee, the Annual Contract Fee has been converted into a per-

        based on the actual average Accumulated Value of the Contracts as of
        December 31, 1999. The charge works out to 0.04% per annum.



               Based on the method of calculation described above, the Adjusted

        National Life Insurance Company is a member of the Insurance

                              FINANCIAL STATEMENTS

      National Life's financial statements as of and for the years ended
December 31, 1999 and 1998, which are included in the Statement of Additional
Information, should be considered only as bearing on National Life's ability to
meet its obligations under the Contracts. They should not be considered as
bearing on the investment performance of the assets held in the Variable
Account.


                             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.

                               LEGAL PROCEEDINGS


The Company, like other life insurance companies, is involved in lawsuits,
including class action lawsuits. In some class action and other lawsuits
involving insurance companies, substantial damages have been sought and/or
material settlement payments have been made. Although the Company cannot predict
the outcome of any litigation with certainty, the Company believes that at the
present time, there are no pending or threatened lawsuits that are reasonably
likely to have a material adverse impact on it or the Variable Account. ESI is
not engaged in any litigation of any material nature.

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 range from 0% to 3.5% of premium
based on the state in which the Contract is sold.



Money Market Subaccount



         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
pre-existing account 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 the base period return on a 365-day
basis, simple interest. 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, the $30 Annual Contract Fee is converted to a per
dollar per day charge. 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 pre-existing account having an initial
                       balance of one Subaccount unit.

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

         UV =          The unit value at the beginning of the seven-day period.

         The effective yield of the Money Market Subaccount determined on a
compound 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 pre-existing
                       account having an initial balance of one Subaccount unit.

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

         UV =          The unit value at the beginning 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,
1999 was 4.09% the effective yield for that Subaccount as of the same date was
4.18%. These yields were calculated based on the performance of the Market
Street Money Market Portfolio for the seven day period ended December 31, 1999,
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 Subaccounts

         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 a 30-day or one-month period. 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
earned during the period by the Portfolio company attributable to shares owned
by the Subaccount less Subaccount expenses for the period; by (2) the maximum
offering price per Subaccount unit on the last day of the period times the
daily average daily number of Subaccount units outstanding for the period; and
3) compounding that yield for a six-month period; and then 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
theyield, the $30 Annual Contract fee is converted to a per dollar per day
charge to determine the amount of this charge attributable to the Subaccount
for the period. The yieldis calculated according to the following formula:

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

         Where:

         NI =    net investment income earned during the period by the
                 Portfolio company attributable to the shares owned by the
                 Subaccount.

         ES =    expenses of the Subaccount for the period.

         U =     the average daily number of Subaccount units outstanding
                 during the period.

         UV =    the maximum offering price per Subaccount unit on the last day
                 of the period. This is equivalent to the unit value at the
                 close of the last day in the 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
Portfolio.

         The yield on the amounts held in the Subaccounts normally will
fluctuate over time. THEREFORE, THE DISCLOSED YIELD OF 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 on
amounts surrendered or withdrawn under the Contract.  The Surrender Charge
ranges 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.  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, 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.

         Standardized average annual total returns represent the average annual
compounded rates of return that would equate a hypothetical initial investment
of $1,000 under a Contract to the redemption value of that investment as of the
last day of the measuring period.  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 returns are calculated using
Subaccount unit values which we calculate on each Valuation Day based on the
performance of the Subaccount's underlying Portfolio and deductions for the
Mortality and Expense Risk Chargeand the Administration Charge.  For purpose of
calculating average annual total returns, the $30 Annual Contract Fee is
converted to a per dollar per day charge to determine the amount of this
charge attributable to the Subaccount for the period.  The calculation also
assumes surrender of the Contract at the end of the period for the return
quotation. Standardized average annual total returns will therefore reflect a
deduction of the CDSC for any period less than seven years.  The standardized
average annual total return is calculated according to the following formula:

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

         Where:

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

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

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

         N =         the number of years in the period.

         Standardized average annual total returns are reported only for
periods during which a given Subaccount was available in the Contract.

         Standardized 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
         Standardized average annual total returns as of December 31, 1999 are
shown in the prospectus.

         B.      Other Total Returns

         Nonstandardized 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 standardized 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.

Nonstandardized average annual total returns as of December 31, 1999 are shown
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 recurring Subaccount
                     charges for the period.

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

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

         Adjusted Historic Average Annual Total Return.  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 average annual total return 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 average annual total return
data will be disclosed together with the standardized average annual total
returns for the required periods.

         The Funds have provided the total return information used to calculate
the adjusted historic average annual 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, Goldman Sachs Variable Insurance Trust,
and Van Eck Global Worldwide Insurance Trust are not affiliated with us.

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
converted based on the average Accumulated Value in the Contracts as of
December 31, 1999. The charge works out to be 0.04% per annum.


                                       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.

                           TAX STATUS OF THE CONTRACTS

            Tax law imposes several requirements that variable annuities must
satisfy in order to receive the tax treatment normally accorded to annuity
contracts.

            Diversification Requirements. The Internal Revenue Code (Code)
requires that the investments of each investment division of the separate
account underlying the Contracts be "adequately diversified" in order for the
Contracts to be treated as annuity contracts for Federal income tax purposes.
It is intended that each investment division, through the fund in which it
invests, will satisfy these diversification requirements.

            Owner Control. In certain circumstances, owners of variable annuity
contracts have been considered for Federal income tax purposes to be the owners
of the assets of the separate account supporting their contracts due to their
ability to exercise investment control over those assets. When this is the
case, the contract owners have been currently taxed on income and gains
attributable to the variable account assets. There is little guidance in this
area, and some features of our Contracts, such as the flexibility of an owner
to allocate premium payments and transfer amounts among the investment
divisions of the separate account, have not been explicitly addressed in
published rulings. While we believe that the Contracts do not give Owners
investment control over separate account assets, we reserve the right to modify
the Contracts as necessary to prevent an Owner from being treated as the Owner
of the separate account assets supporting the Contract.

            Required Distributions. In order to be treated as an annuity
contract for Federal income tax purposes, Section 72(s) of the Code requires
any Non-Qualified Contract to contain certain provisions specifying how your
interest in the Contract will be distributed in the event of the death of an
owner of the Contract. Specifically, section 72(s) requires that (a) if any
owner dies on or after the annuity starting date, but prior to the time the
entire interest in the contract has been distributed, the entire interest in
the contract will be distributed at least as rapidly as under the method of
distribution being used as of the date of such owner's death; and (b) if any
owner dies prior to the annuity starting date, the entire interest in the
contract will be distributed within five years after the date of such owner's
death. These requirements will be considered satisfied as to any portion of a
owner's interest which is payable to or for the benefit of a designated
beneficiary and which is distributed over the life of such designated
beneficiary or over a period not extending beyond the life expectancy of that
beneficiary, provided that such distributions begin within one year of the
owner's death. The designated beneficiary refers to a natural person designated
by the owner as a beneficiary and to whom ownership of the contract passes by
reason of death. However, if the designated beneficiary is the surviving spouse
of the deceased owner, the contract may be continued with the surviving spouse
as the new owner.

            The Non-Qualified Contracts contain provisions that are intended to
comply with these Code requirements, although no regulations interpreting these
requirements have yet been issued. We intend to review such provisions and
modify them if necessary to assure that they comply with the applicable
requirements when such requirements are clarified by regulation or otherwise.

            Other rules may apply to Qualified Contracts.

                        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 underwriting commissions of
$4,862,631, $2,382,082, and $691,647 in 1999, 1998, and 1997 respectively, and
retained $4,201,190, $2,206,648, and $674,055 in 1999, 1998, and 1997
respectively.

                          SAFEKEEPING OF ACCOUNT ASSETS

        National Life holds the title to the assets of the Variable Account. The
assets are kept physically segregated and held separate and apart from the
Company's General Account assets and from the assets in any other separate
account.

         Records are maintained of all purchases and redemptions of Fund shares
held by each of the Subaccounts.

                                STATE REGULATION

        National Life is subject to regulation and supervision by the Insurance
Department of the State of Vermont which periodically examines its affairs. It
is also subject to the insurance laws and regulations of all jurisdictions where
it is authorized to do business. A copy of the Contract form has been filed
with, and where required approved by, insurance officials in each jurisdiction
where the Contracts are sold. National Life is required to submit annual
statements of its operations, including financial statements, to the insurance
departments of the various jurisdictions in which it does business for the
purposes of determining solvency and compliance with local insurance laws and
regulations.

                               RECORDS AND REPORTS

        National Life will maintain all records and accounts relating to the
Variable Account. As presently required by the Investment Company Act of 1940
and regulations promulgated thereunder, reports containing such information as
may be required under the Act or by any other applicable law or regulation will
be sent to Contract Owners semi-annually at the last address known to the
Company.

                                  LEGAL MATTERS

        All matters relating to Vermont law pertaining to the Contracts,
including the validity of the Contracts and National Life's authority to issue
the Contracts, have been passed upon by Michele S. Gatto, Senior Vice President
& General Counsel of National Life. Sutherland, Asbill & Brennan LLP

                              FINANCIAL STATEMENTS

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

                                   -UNAUDITED-
- --------------------------------------------------------------------------------
On January 1, 1999, National Life Insurance Company (National Life) converted
from a mutual to a stock insurance company as part of a reorganization into a
mutual holding company corporate structure. Prior to the conversion,
policyowners held policy contractual and membership rights from National Life.
The contractual rights, as defined in the various insurance and annuity
policies, remained with National Life after the conversion. Membership interests
held by policyowners of National Life at December 31, 1998 were converted to
membership interests in National Life Holding Company, a mutual insurance
holding company created for this purpose. Policyholders of National Life with
policies issued after December 31, 1998 also become members of National Life
Holding Company.

As part of this reorganization, National Life established and began operating a
closed block (the Closed Block) on January 1, 1999. The Closed Block was
established pursuant to regulatory requirements as part of the reorganization,
and was established for the benefit of policyholders of participating policies
inforce at December 31, 1998. Notes 2, 11 and 13 of National Life's financial
statements provide additional information about the Closed Block.

Under current accounting guidance, National Life's assets, liabilities, pre-tax
net income and cash flows associated with the Closed Block were reclassified
into single line net presentations within National Life Insurance Company and
Subsidiaries' financial statements, and excluded from many of the disclosures
contained in the corresponding notes to those financial statements.

The American Institute of Certified Public Accountants has proposed changes to
the accounting treatment for Closed Blocks. Included in the proposal is the
presentation of Closed Block assets, liabilities, pre-tax net income and cash
flows in their normal categories, instead of the current single line net
presentations. It is currently anticipated that this proposal will be adopted
retroactively for all presented periods beginning with December 31, 2000
reporting.

Management of National Life has therefore elected to also include consolidated
financial statements prepared at the National Life Holding Company level. These
financial statements do not reflect the closed block single line net
presentation, and therefore should provide more comparable year to year
information for the reader.

                        REPORT OF INDEPENDENT ACCOUNTANTS





To the Board of Directors and Members of
National Life Holding Company:



In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations and comprehensive income, changes in
equity, and cash flows present fairly, in all material respects, the financial
position of National Life Holding Company and its subsidiaries (the National
Life Group) at December 31, 1999 and 1998, and the results of their operations
and their cash flows for the years then ended in conformity with accounting
principles generally accepted in the United States. These financial statements
are the responsibility of National Life Group's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

As discussed in Note 13 to the financial statements, on January 1, 1999,
National Life converted from a mutual to a stock insurance company as part of a
reorganization into a mutual holding company corporate structure. Members'
voting and liquidation rights in National Life were transferred to National Life
Holding Company as part of this reorganization.

NATIONAL LIFE GROUP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - NATURE OF OPERATIONS

National Life Holding Company and its subsidiaries and affiliates (the National
Life Group) offer a broad range of financial products and services, including
life insurance, annuities, disability income insurance, mutual funds, and
investment advisory and administration services. The flagship company of the
organization, National Life Insurance Company (National Life), was chartered in
1848, and is also known by its registered trade name "National Life of Vermont".
National Life Group employs about 900 people, primarily concentrated in
Montpelier, Vermont and Dallas, Texas. On January 1, 1999, pursuant to a mutual
holding company reorganization, National Life converted from a mutual to a stock
life insurance company. All of National Life's outstanding shares are currently
held by its parent, NLV Financial Corp, which is the wholly-owned subsidiary of
National Life Holding Company. See Note 13 for more information.

The insurance operations within National Life Group develop and distribute
individual life insurance and annuity products. National Life Group markets this
diverse product portfolio to small business owners, professionals and other
middle to upper income individuals. National Life Group provides financial
solutions in the form of estate, business succession and retirement planning,
deferred compensation and other key executive fringe benefit plans, and asset
management. Insurance and annuity products are primarily distributed through
about 32 general agencies in major metropolitan areas, a system of managing
general agents, and independent brokers throughout the United States. National
Life Group has in excess of 300,000 policyholders and through its member
companies is licensed to do business in all 50 states and the District of
Columbia. About 26% of National Life Group's total collected premiums and
deposits are from residents of New York and California.

Members of the National Life Group also distribute and provide investment
advisory and administrative services to the Sentinel Group Funds, Inc. The
Sentinel Funds' $3.1 billion of net assets represent fourteen mutual funds
managed on behalf of about 117,000 individual, corporate and institutional
shareholders worldwide.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The accompanying consolidated financial statements of National Life Group have
been prepared in conformity with accounting principles generally accepted in the
United States (GAAP).

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

The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

INVESTMENTS

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




                                      F-8
<PAGE>   80

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

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

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

Real estate investments are reported at depreciated cost. Real estate acquired
in satisfaction of debt is transferred to real estate at estimated fair value.
Investments in joint ventures and limited partnerships are generally carried at
cost.

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

POLICY ACQUISITION EXPENSES

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

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

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

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

PRESENT VALUE OF FUTURE PROFITS OF INSURANCE ACQUIRED

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

GOODWILL

Goodwill is amortized over 20 years using the straight line method and is
periodically evaluated for recoverability.



                                      F-9
<PAGE>   81

PROPERTY AND EQUIPMENT

Property and equipment is reported at depreciated cost. Real property is
primarily depreciated over 39.5 years using the straight-line method. Furniture
and equipment is depreciated using accelerated depreciation methods over 7 years
and 5 years, respectively.

SEPARATE ACCOUNTS

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

POLICY LIABILITIES

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

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

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

POLICYHOLDERS' DIVIDENDS

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

RECOGNITION OF INSURANCE INCOME AND RELATED EXPENSES

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

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

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



                                      F-10
<PAGE>   82

FEDERAL INCOME TAXES

National Life Holding Company will file a consolidated tax return for the tax
year ended December 31, 1999. The income tax return will include all members
within the National Life Group except Life Insurance Company of the Southwest
(LSW) and Insurance Investors Life Insurance Company (IIL). LSW and IIL will
file a separate tax return due to tax regulatory requirements. Current federal
income taxes are charged or credited to operations based upon amounts estimated
to be payable or recoverable as a result of taxable operations for the current
year. Deferred income tax assets and liabilities are recognized based on
temporary differences between financial statement carrying amounts and income
tax bases of assets and liabilities using enacted income tax rates and laws.

MINORITY INTERESTS

Minority interests at December 31, 1999 represent minority partners interests in
entities within the National Life Group. Minority interests attributable to
common stockholders are carried on the equity method. Those attributable to
preferred stockholders are carried on the cost method, with dividends paid
reflected as minority interests within the consolidated financial statements.

CLOSED BLOCK

National Life established and began operating a closed block (the Closed Block)
on January 1, 1999. The Closed Block was established pursuant to regulatory
requirements as part of the reorganization into a mutual holding company
corporate structure. This Closed Block was established for the benefit of
policyholders of participating policies inforce at December 31, 1998. Included
in the block are traditional dividend paying life insurance policies, certain
participating term insurance policies, dividend paying flex premium annuities,
and other related liabilities. The Closed Block was established to protect the
policy dividend expectations related to these policies. The Closed Block is
expected to remain in effect until all policies within the Closed Block are no
longer inforce. Assets assigned to the Closed Block at January 1, 1999, together
with projected future premiums and investment returns, are reasonably expected
to be sufficient to pay out all future Closed Block policy benefits. Such
benefits include dividends paid out under the current dividend scale, adjusted
to reflect future changes in the underlying experience. See Note 11 for
additional information on the Closed Block's financial position and results of
operations.

Net other comprehensive (loss) income for 1999 and 1998 of $(163.9) million and
$21.2 million is presented net of reclassifications to net income for gross
gains realized during the period of $13.9 million and $9.0 million and net of
tax and deferred acquisition cost offsets of $9.4 million and $6.6 million,
respectively.

The amortized cost and estimated fair values of debt securities by contractual
maturity at December 31, 1999 are shown below (in thousands). Expected
maturities may differ from contractual maturities because borrowers may have the
right to call or prepay obligations with or without call or prepayment

On January 1, 1999, National Life Group reclassified certain mutual fund
investments from an available-for-sale to a trading classification. The
cumulative gross unrealized gain reclassified into net investment gains was $0.6
million. For the year ended December 31, 1999, these securities recorded $0.9
million net investment income and $(0.5) million investment losses. Cost of
trading securities held at December 31, 1999 was $12.1 million. National Life
Group held no securities classified as trading prior to January 1, 1999.

National Life Group periodically lends certain U.S. government or corporate
bonds to approved counterparties to enhance the yield of its bond portfolio.
National Life receives cash collateral for at least 103% of the market value of
securities loaned. Collateral adequacy is evaluated daily and periodically
adjusted for changes in the market value of securities loaned. The carrying
values of securities loaned are unaffected by the transaction. Collateral held
(included in cash and cash equivalents) and the corresponding liability for
collateral held were $115.5 million and $193.5 million at December 31, 1999 and
1998, respectively.

National Life Group also periodically enters into repurchase agreements on U.S.
Treasury securities to enhance the yield of its bond portfolio. These
transactions are accounted for as financings because the securities received at
the end of the repurchase period are identical to the securities transferred.
There were no open transactions at December 31, 1999 or 1998.

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

DERIVATIVES


National Life Group purchases over-the-counter options and exchange-traded
futures on the Standard & Poor's 500 (S&P 500) index to hedge obligations
relating to equity indexed products. When the S&P 500 index increases, increases
in the intrinsic value of the options and fair value of futures are offset by

increases in equity indexed product account values. When the S&P 500 index
decreases, National Life Group's loss is the decrease in the fair value of
futures and is limited to the premium paid for the options.

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

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

The notional amounts and net book value of options and futures at December 31
were as follows (in thousands):

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

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

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

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

Derivatives estimated fair values are based on quoted values.

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

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

NOTE 4 - INSURANCE IN-FORCE AND REINSURANCE

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

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

Transactions between the open and Closed Block (see Notes 11 and 13) have been
excluded from the following schedule.

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

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

National Life's federal income tax returns are routinely audited by the IRS. The
IRS has examined National Life's tax returns through 1995 and is currently
examining the years 1996 - 1998. In management's opinion adequate tax
liabilities have been established for all open years.

NOTE 7 - BENEFIT PLANS

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

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

During 1997, National Life offered enhanced pension and postretirement benefits
to employees meeting certain defined eligibility requirements. The program
resulted in special termination benefits for the expected present value of the
enhancements to benefits, curtailment gains for reductions in the pension
benefit obligations relating to assumed increases in future compensation levels
and settlement gains for the pro-rata recognition of actuarial gains on lump sum
settlements of pension benefit obligations. Some of the plan participants
elected to defer their lump sum payouts until 1998, which also deferred
recognition of the related settlement gain until 1998.

Health care cost trend rates grade to 5% in year 2000 and remain level
thereafter. Increasing the assumed health care trend rates by one percentage
point in each year would increase the APBO by about $2.4 million and the 1999
service and interest cost components of net periodic postretirement benefit cost
by about $0.1 million. Decreasing the assumed health care trend rates by one
percentage point in each year would reduce the APBO by about $2.0 million and
the 1999 service and interest cost components of net periodic postretirement
benefit cost by about $0.1 million. National Life Group uses the straight-line
method of amortization for prior service cost and unrecognized gains and losses.

National Life provides employee savings and 401(k) plans where up to 3% of an
employee's compensation may be invested by the employee in either plan with
matching funds contributed by the company. Employees below specified levels of
compensation also receive a foundation contribution of 1.5% of compensation.
Additional employee voluntary contributions may be made to the plans up to a set
maximum. Vesting and withdrawal privilege schedules are attached to the
Company's contributions.

National Life also provides a 401(k) plan for it's regular full-time agents
whereby accumulated funds may be invested by the agent in a group annuity
contract with National Life or in mutual funds sponsored by an affiliate of
National Life. Total annual contributions can not exceed certain limits that
vary based on total agent compensation. No National Life contributions are made
to the plan.

Life Insurance Company of the Southwest (LSW), an indirectly held wholly-owned
subsidiary of National Life, provides a 401(k) to its employees. Additional
voluntary employee contributions may be made to the plan subject to certain
limits. LSW's contributions to these plans generally vest within two years.

NOTE 9 - CONTINGENCIES

During 1997, several class action lawsuits were filed against National Life in
various states related to the sale of life insurance policies during the 1980's
and 1990's. National Life specifically denied any wrongdoing. National Life
agreed to a settlement of these class action lawsuits in June 1998. This
agreement was subsequently approved by the court in October 1998. The settlement
provides class members with various policy enhancement options and new product
purchase discounts. Class members may instead pursue alternative dispute
resolution according to predetermined guidelines. Qualifying members may also
opt out of the class action and pursue litigation separately against National
Life. Most of the alternative dispute resolution cases were settled by December
31, 1999. Management believes that while the ultimate cost of this litigation
(including those opting out of the class action) is still uncertain, it is
unlikely, after considering existing provisions, to have a material adverse
effect on National Life's financial position.

In late 1999, two lawsuits were filed against National Life and the State of
Vermont in Vermont related to National Life's conversion to a mutual holding
company structure. National Life and the State of Vermont specifically deny any
wrongdoing and intend to defend these cases vigorously. In the opinion of
National Life Group's management, based on advice from legal counsel, the
ultimate resolution of these lawsuits will not have a material effect on
National Life Group's financial position. However, liabilities related to these
lawsuits could be established in the near term if estimates of the ultimate
resolution of these proceedings are revised.

NOTE 10 - NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities (FAS 133), which establishes accounting and reporting
standards for derivative instruments. FAS 133 requires that an entity recognize
all derivatives as either assets or liabilities at fair value in the statement
of financial position, and establishes special accounting for the following
three types of hedges: fair value hedges, cash flow hedges, and hedges of
foreign currency exposures of net investments in foreign operations. The
statement was originally effective for fiscal years beginning after June 15,
1999. In June, 1999 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 137, Accounting for Derivative Instruments
and Hedging Activities - Deferral of the Effective Date of FASB Statement No.
133 (FAS 137). FAS 137 requires the application of FAS 133 for fiscal years
beginning after June 15, 2000. National Life Group is currently assessing the
impact of the adoption of FAS 133.

NOTE 11 - CLOSED BLOCK

There were no mortgage valuation allowances on Closed Block mortgage loans at
December 31, 1999. Many expenses related to Closed Block operations are charged
to operations outside the Closed Block; accordingly, the contribution from the
Closed Block does not represent the actual profitability of the Closed Block
operations. Operating costs and expenses outside the Closed Block are therefore
disproportionate to the actual business outside the Closed Block.

NOTE 12 - ACQUISITION

On July 2, 1999, National Life Group acquired the outstanding one-third interest
in LSW National Holdings, Inc., (LSWNH) the parent of Dallas, Texas-based Life
Insurance Company of the Southwest (LSW), a financial services company
specializing in the sale of annuities. National Life Group had previously
purchased a two-thirds interest in the company in February, 1996.

The purchase price was $61.6 million in cash. Purchasing the remaining one-third
interest eliminated the ongoing provision for minority interests for the last
six months of 1999. The effect of the cash purchase on the consolidated
financial statements was to reduce minority interests by $39.7 million and
record net purchase GAAP adjustments of $21.9 million, which included intangible
assets for the present value of future profits of insurance acquired of $59.4
million and goodwill of $3.0 million.

Had the one-third purchase been made at January 1, 1998, pro-forma consolidated
net income would have increased by about $3.1 million and $2.2 million in 1999
and 1998, respectively. These pro-forma consolidated results are not necessarily
indicative of the actual results which might have occurred had National Life
Group owned all of LSWNH since that date. (unaudited)

NOTE 13 - REORGANIZATION INTO A MUTUAL HOLDING COMPANY
          CORPORATE STRUCTURE

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

Prior to the conversion, policyowners held policy contractual and membership
rights from National Life. The contractual rights, as defined in the various
insurance and annuity policies, remained with National Life after the
conversion. Membership interests held by policyowners of National Life at
December 31, 1998 were converted to membership interests in National Life
Holding Company, a mutual insurance holding company created for this purpose.
National Life Holding Company currently owns all the outstanding shares of NLV
Financial, a stock holding company created for this purpose, which in turn
currently owns all the outstanding shares of National Life. National Life
Holding Company currently has no other assets, liabilities or operations other
than that related to its ownership of NLV Financial's outstanding stock.
Similarly, NLV Financial currently has no other assets, liabilities or
operations other than that related to its ownership of National Life's
outstanding stock. Under the terms of the reorganization, National Life Holding
Company must always hold a majority of the voting shares of NLV Financial.

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

Under the provisions of the reorganization, National Life issued 2.5 million
common stock $1 par shares to its parent, NLV Financial as a transfer from
retained earnings. There were no dividends paid or declared in 1999 by National
Life. Dividends declared by National Life in excess of ten percent of statutory
surplus (see Note 14 for statutory information) require pre-approval by the
Commissioner.

The New York Insurance Department recognizes only statutory accounting practices
for determining and reporting the financial condition and results of operations
of an insurance company and for determining solvency under the New York
Insurance Law. No consideration is given by the New York Insurance Department to
financial statements prepared in accordance with generally accepted accounting
principles in making such determinations.

In 1998, the National Association of Insurance Commissioners (NAIC) adopted the
Codification of Statutory Accounting Principles guidance (Codification), which
will replace the current Accounting Practices and Procedures manual as the
NAIC's primary guidance on statutory accounting. The NAIC has recommended an
effective date of January 1, 2001. The Codification provides guidance for areas
which promulgated statutory accounting principles had not previously addressed,
and changes current promulgated guidance in other areas.

The Vermont Department of Banking, Insurance, Securities, and Health Care
Administration has adopted Codification effective January 1, 2001. The
Department may make changes to the promulgated guidance prior to the effective
date. National Life has not estimated the potential effect of the Codification
guidance on its reported results.

                        Report of Independent Accountants





To the Board of Directors and Stockholder of
National Life Insurance Company:


In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations and comprehensive income, changes in
equity, and cash flows present fairly, in all material respects, the financial
position of National Life Insurance Company and its subsidiaries (National
Life) at December 31, 1999 and 1998, and the results of their operations and
their cash flows for the years then ended in conformity with accounting
principles generally accepted in the United States. These financial statements
are the responsibility of National Life's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for the
opinion expressed above.


As discussed in Note 13 to the financial statements, on January 1, 1999,
National Life converted from a mutual to a stock insurance company as part of a
reorganization into a mutual holding company corporate structure. Members'
voting and liquidation rights in National Life were transferred to National Life
Holding Company, the upstream parent of National Life, as part of this
reorganization.

NATIONAL LIFE INSURANCE COMPANY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - NATURE OF OPERATIONS

National Life Insurance Company and its subsidiaries and affiliates (the
Company) offer a broad range of financial products and services, including life
insurance, annuities, disability income insurance, mutual funds, and investment
advisory and administration services. The flagship company of the organization,
National Life Insurance Company (National Life), was chartered in 1848, and is
also known by its registered trade name "National Life of Vermont". The Company
employs about 900 people, primarily concentrated in Montpelier, Vermont and
Dallas, Texas. On January 1, 1999, pursuant to a mutual holding company
reorganization, National Life converted from a mutual to a stock life insurance
company. All of National Life's outstanding shares are currently held by its
parent, NLV Financial Corp, which is the wholly-owned subsidiary of National
Life Holding Company. See Note 13 for more information.

The insurance operations within the Company develop and distribute individual
life insurance and annuity products. The Company markets this diverse product
portfolio to small business owners, professionals and other middle to upper
income individuals. The Company provides financial solutions in the form of
estate, business succession and retirement planning, deferred compensation and
other key executive fringe benefit plans, and asset management. Insurance and
annuity products are primarily distributed through about 32 general agencies in
major metropolitan areas, a system of managing general agents, and independent
brokers throughout the United States. The Company has in excess of 300,000
policyholders and through its member companies is licensed to do business in all
50 states and the District of Columbia. About 26% of the Company's total
collected premiums and deposits are from residents of New York and California.

Members of the Company also distribute and provide investment advisory and
administrative services to the Sentinel Group Funds, Inc. The Sentinel Funds'
$3.1 billion of net assets represent fourteen mutual funds managed on behalf of
about 117,000 individual, corporate and institutional shareholders worldwide.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The accompanying consolidated financial statements of the Company have been
prepared in conformity with accounting principles generally accepted in the
United States (GAAP).

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

The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

INVESTMENTS

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



                                      F-32
<PAGE>   104

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

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

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

Real estate investments are reported at depreciated cost. Real estate acquired
in satisfaction of debt is transferred to real estate at estimated fair value.
Investments in joint ventures and limited partnerships are generally carried at
cost.

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

POLICY ACQUISITION EXPENSES

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

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

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

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

PRESENT VALUE OF FUTURE PROFITS OF INSURANCE ACQUIRED

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

GOODWILL

Goodwill is amortized over 20 years using the straight line method and is
periodically evaluated for recoverability.



                                      F-33
<PAGE>   105

PROPERTY AND EQUIPMENT

Property and equipment is reported at depreciated cost. Real property is
primarily depreciated over 39.5 years using the straight-line method. Furniture
and equipment is depreciated using accelerated depreciation methods over 7 years
and 5 years, respectively.

SEPARATE ACCOUNTS

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

POLICY LIABILITIES

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

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

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

POLICYHOLDERS' DIVIDENDS

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

RECOGNITION OF INSURANCE INCOME AND RELATED EXPENSES

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

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

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

FEDERAL INCOME TAXES

National Life Holding Company will file a consolidated tax return for the tax
year ended December 31, 1999. The income tax return will include all members
within the Company except Life Insurance Company of the Southwest (LSW) and
Insurance Investors Life Insurance Company (IIL). LSW and IIL will file a
separate tax return due to tax regulatory requirements. Current federal income
taxes are charged or credited to operations based upon amounts estimated to be
payable or recoverable as a result of taxable operations for the current year.
Deferred income tax assets and liabilities are recognized based on temporary
differences between financial statement carrying amounts and income tax bases of
assets and liabilities using enacted income tax rates and laws.

MINORITY INTERESTS

Minority interests at December 31, 1999 represent minority partners interests in
entities within the Company. Minority interests attributable to common
stockholders are carried on the equity method. Those attributable to preferred
stockholders are carried on the cost method, with dividends paid reflected as
minority interests within the consolidated financial statements.

CLOSED BLOCK

National Life established and began operating a closed block (the Closed Block)
on January 1, 1999. The Closed Block was established pursuant to regulatory
requirements as part of the reorganization into a mutual holding company
corporate structure. This Closed Block was established for the benefit of
policyholders of participating policies inforce at December 31, 1998. Included
in the block are traditional dividend paying life insurance policies, certain
participating term insurance policies, dividend paying flex premium annuities,
and other related liabilities. The Closed Block was established to protect the
policy dividend expectations related to these policies. The Closed Block is
expected to remain in effect until all policies within the Closed Block are no
longer inforce. Assets assigned to the Closed Block at January 1, 1999, together
with projected future premiums and investment returns, are reasonably expected
to be sufficient to pay out all future Closed Block policy benefits. Such
benefits include dividends paid out under the current dividend scale, adjusted
to reflect future changes in the underlying experience. See Note 11 for
additional information on the Closed Block's financial position and results of
operations.

On January 1, 1999, National Life Group reclassified certain mutual fund
investments from an available-for-sale to a trading classification. The
cumulative gross unrealized gain reclassified into net investment gains was $0.6
million. For the year ended December 31, 1999, these securities recorded $0.9
million net investment income and $(0.5) million investment losses. Cost of
trading securities held at December 31, 1999 was $12.1 million. National Life
Group held no securities classified as trading prior to January 1, 1999.

National Life Group periodically lends certain U.S. government or corporate
bonds to approved counterparties to enhance the yield of its bond portfolio.
National Life receives cash collateral for at least 103% of the market value of
securities loaned. Collateral adequacy is evaluated daily and periodically
adjusted for changes in the market value of securities loaned. The carrying
values of securities loaned are unaffected by the transaction. Collateral held
(included in cash and cash equivalents and closed block assets) and the
corresponding liability for collateral held (closed block portion included in
closed block liabilities) were $115.5 million and $193.5 million at December 31,
1999 and 1998, respectively.

National Life Group also periodically enters into repurchase agreements on U.S.
Treasury securities to enhance the yield of its bond portfolio. These
transactions are accounted for as financings because the securities received at
the end of the repurchase period are identical to the securities transferred.
There were no open transactions at December 31, 1999 or 1998.

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

DERIVATIVES

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

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

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

The notional amounts and net book value of options and futures at December 31
were as follows (in thousands):

interest rates of similar securities.

NOTE 4 - INSURANCE IN-FORCE AND REINSURANCE

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

The Company remains liable in the event any reinsurer is unable to meet its
assumed obligations. The Company regularly evaluates the financial condition of
its reinsurers and concentrations of credit risk of reinsurers to minimize its
exposure to significant losses from reinsurer insolvencies.
,
Transactions between the open and Closed Block (see Notes 11 and 13) have been
excluded from the following schedule. Reinsurance flows with outside parties
remain within the open block.

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

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

National Life's federal income tax returns are routinely audited by the IRS. The
IRS has examined National Life's tax returns through 1995 and is currently
examining the years 1996 - 1998. In management's opinion adequate tax
liabilities have been established for all open years.

NOTE 7 - BENEFIT PLANS

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

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

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



                                      F-43
<PAGE>   115

the pro-rata recognition of actuarial gains on lump sum settlements of pension
benefit obligations. Some of the plan participants elected to defer their lump
sum payouts until 1998, which also deferred recognition of the related
settlement gain until 1998.

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

Health care cost trend rates grade to 5% in year 2000 and remain level
thereafter. Increasing the assumed health care trend rates by one percentage
point in each year would increase the APBO by about $2.4 million and the 1999
service and interest cost components of net periodic postretirement benefit cost
by about $0.1 million. Decreasing the assumed health care trend rates by one
percentage point in each year would reduce the APBO by about $2.0 million and
the 1999 service and interest cost components of net periodic postretirement
benefit cost by about $0.1 million. National Life Group uses the straight-line
method of amortization for prior service cost and unrecognized gains and losses.

National Life provides employee savings and 401(k) plans where up to 3% of an
employee's compensation may be invested by the employee in either plan with
matching funds contributed by the company. Employees below specified levels of
compensation also receive a foundation contribution of 1.5% of compensation.
Additional employee voluntary contributions may be made to the plans up to a set
maximum. Vesting and withdrawal privilege schedules are attached to the
Company's contributions.

National Life also provides a 401(k) plan for it's regular full-time agents
whereby accumulated funds may be invested by the agent in a group annuity
contract with National Life or in mutual funds sponsored by an affiliate of
National Life. Total annual contributions can not exceed certain limits that
vary based on total agent compensation. No National Life contributions are made
to the plan.

Life Insurance Company of the Southwest (LSW), an indirectly held wholly-owned
subsidiary of National Life, provides a 401(k) to its employees. Additional
voluntary employee contributions may be made to the plan subject to certain
limits. LSW's contributions to these plans generally vest within two years.

NOTE 9 - CONTINGENCIES

During 1997, several class action lawsuits were filed against National Life in
various states related to the sale of life insurance policies during the 1980's
and 1990's. National Life specifically denied any wrongdoing. National Life
agreed to a settlement of these class action lawsuits in June 1998. This
agreement was subsequently approved by the court in October 1998. The settlement
provides class members with various policy enhancement options and new product
purchase discounts. Class members may instead pursue alternative dispute
resolution according to predetermined guidelines. Qualifying members may also
opt out of the class action and pursue litigation separately against National
Life. Most of the alternative dispute resolution cases were settled by December
31, 1999. Management believes that while the ultimate cost of this litigation
(including those opting out of the class action) is still uncertain, it is
unlikely, after considering existing provisions, to have a material adverse
effect on National Life's financial position.

In late 1999, two lawsuits were filed against National Life and the State of
Vermont in Vermont related to National Life's conversion to a mutual holding
company structure. National Life and the State of Vermont specifically deny any
wrongdoing and intend to defend these cases vigorously. In the opinion of
National Life Group's management, based on advice from legal counsel, the
ultimate resolution of these lawsuits will not have a material effect on
National Life Group's financial position. However, liabilities related to these
lawsuits could be established in the near term if estimates of the ultimate
resolution of these proceedings are revised.

NOTE 10 - NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities (FAS 133), which establishes accounting and reporting
standards for derivative instruments. FAS 133 requires that an entity recognize
all derivatives as either assets or liabilities at fair value in the statement
of financial position, and establishes special accounting for the following
three types of hedges: fair value hedges, cash flow hedges, and hedges of
foreign currency exposures of net investments in foreign operations. The
statement was originally effective for fiscal years beginning after June 15,
1999. In June, 1999 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 137, Accounting for Derivative Instruments
and Hedging Activities - Deferral of the Effective Date of FASB Statement No.
133 (FAS 137). FAS 137 requires the application of FAS 133 for fiscal years
beginning after June 15, 2000. The Company is currently assessing the impact of
the adoption of FAS 133.

There were no mortgage valuation allowances on Closed Block mortgage loans at
December 31, 1999. Many expenses related to Closed Block operations are charged
to operations outside the Closed Block; accordingly, the contribution from the
Closed Block does not represent the actual profitability of the Closed Block
operations. Operating costs and expenses outside the Closed Block are therefore
disproportionate to the actual business outside the Closed Block.

The Consolidated Statement of Cash Flows for 1999 is presented net of cash flows
and adjustments to operating cash flows attributable to the Closed Block cash
and short term investments of $(24.5) million. The Closed Block was initially
funded on January 1, 1999 with cash and securites totalling $2.2 billion.

NOTE 12 - ACQUISITION

On July 2, 1999, the Company acquired the outstanding one-third interest in LSW
National Holdings, Inc., (LSWNH) the parent of Dallas, Texas-based Life
Insurance Company of the Southwest (LSW), a financial services company
specializing in the sale of annuities. The Company had previously purchased a
two-thirds interest in the company in February, 1996.

The purchase price was $61.6 million in cash. Purchasing the remaining one-third
interest eliminated the ongoing provision for minority interests for the last
six months of 1999. The effect of the cash purchase on the consolidated
financial statements was to reduce minority interests by $39.7 million and
record net purchase GAAP adjustments of $21.9 million, which included intangible
assets for the present value of future profits of insurance acquired of $59.4
million and goodwill of $3.0 million.

Had the one-third purchase been made at January 1, 1998, pro-forma consolidated
net income would have increased by about $3.1 million and $2.2 million in 1999
and 1998, respectively. These pro-forma consolidated results are not necessarily
indicative of the actual results which might have occurred had the Company owned
all of LSWNH since that date. (unaudited)

NOTE 13 - REORGANIZATION INTO A MUTUAL HOLDING COMPANY
          CORPORATE STRUCTURE

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

Prior to the conversion, policyowners held policy contractual and membership
rights from National Life. The contractual rights, as defined in the various
insurance and annuity policies, remained with National Life after the
conversion. Membership interests held by policyowners of National Life at
December 31, 1998 were converted to membership interests in National Life
Holding Company, a mutual insurance holding company created for this purpose.
National Life Holding Company currently owns all the outstanding shares of NLV
Financial, a stock holding company created for this purpose, which in turn
currently owns all the outstanding shares of National Life. National Life
Holding Company currently has no other assets, liabilities or operations other
than that related to its ownership of NLV Financial's outstanding stock.
Similarly, NLV Financial currently has no other assets, liabilities or
operations other than that related to its ownership of National Life's
outstanding stock. Under the terms of the reorganization, National Life Holding
Company must always hold a majority of the voting shares of NLV Financial.

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

Under the provisions of the reorganization, National Life issued 2.5 million
common stock $1 par shares to its parent, NLV Financial as a transfer from
retained earnings and also transferred $5 million from retained earnings into
additional paid in capital. There were no dividends paid or declared in 1999 by
National Life. Dividends declared by National Life in excess of ten percent of
statutory surplus (see Note 14 for statutory information) require pre-approval
by the Commissioner.

The New York Insurance Department recognizes only statutory accounting practices
for determining and reporting the financial condition and results of operations
of an insurance company and for determining solvency under the New York
Insurance Law. No consideration is given by the New York Insurance Department to
financial statements prepared in accordance with generally accepted accounting
principles in making such determinations.

In 1998, the National Association of Insurance Commissioners (NAIC) adopted the
Codification of Statutory Accounting Principles guidance (Codification), which
will replace the current Accounting Practices and Procedures manual as the
NAIC's primary guidance on statutory accounting. The NAIC has recommended an
effective date of January 1, 2001. The Codification provides guidance for areas
which promulgated statutory accounting principles had not previously addressed,
and changes current promulgated guidance in other areas.

The Vermont Department of Banking, Insurance, Securities, and Health Care
Administration has adopted Codification effective January 1, 2001. The
Department may make changes to the promulgated guidance prior to the effective
date. National Life has not estimated the potential effect of the Codification
guidance on its reported results.

                       REPORT OF INDEPENDENT ACCOUNTANTS
                       ---------------------------------

To the Board of Directors of National Life Insurance Company
and Contractholders of National Variable Annuity Account II


In our opinion, the accompanying statement of net assets and the related
statements of operations and of changes in net assets present fairly, in all
material respects, the financial position of each of the sub-accounts
constituting the National Variable Annuity Account II (a Separate Account of
National Life Insurance Company) (the Variable Account) at December 31, 1999,
and the results of each of their operations and the changes in each of their
net assets for the years ended December 31, 1999 and 1998 and for the period
from June 20, 1997 through December 31, 1997, in conformity with accounting
principles generally accepted in the United States. These financial
statements are the responsibility of the Variable Account's management; our
responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements in
accordance with auditing standards generally accepted in the United States
which require that we plan and perform the audits to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at December 31, 1999 by
correspondence with the funds, provide a reasonable basis for the opinion
expressed above.

NATIONAL VARIABLE ANNUITY ACCOUNT II
(A Separate Account of National Life Insurance Company)
NOTES TO THE FINANCIAL STATEMENTS


NOTE 1 - NATURE OF OPERATIONS

National Variable Annuity Account II (the Variable Account) began operations on
June 20, 1997 and is registered as a unit investment trust under the Investment
Company Act of 1940, as amended. The operations of the Variable Account are
part of National Life Insurance Company (National Life). The Variable
Account was established by National Life as a separate investment account to
invest the net premiums received from the sale of certain variable annuity
products. Equity Services, Inc., an indirect wholly-owned subsidiary of National
Life, is the principal underwriter for the variable annuity contracts issued by
National Life. Sentinel Advisors Company, an indirectly-owned subsidiary of
National Life, provides investment advisory services for certain Market Street
Fund, Inc. mutual fund portfolios.

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

There are twenty-seven sub-accounts within the Variable Account. Each
sub-account, which invests exclusively in the shares of the corresponding
portfolio, comprises the accumulated contractholder account values of the
underlying variable annuity contracts investing in the sub-account.


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENTS

The mutual fund portfolios consist of the Market Street Fund Money Market,
Market Street Fund Growth, Market Street Fund Aggressive Growth, Market Street
Fund Managed, Market Street Fund Bond, Market Street Fund International, Market
Street Fund Sentinel Growth, Strong Opportunity Fund II, Strong Variable
Insurance Funds Mid Cap Growth, Van Eck Worldwide Insurance Trust Worldwide Bond
Fund, VIPF Equity Income, VIPF Overseas, VIPF Growth, VIPF High Income, VIPF
Index 500, VIPF Contrafund, Alger American Fund Growth, Alger American Fund
Small Capitalization, American Century Variable Portfolios VP Value, American
Century Variable Portfolios VP Income & Growth, JP Morgan Series Trust II
International Opportunities, JP Morgan Series Trust II Small Company, Neuberger
Berman Advisers Management Trust Partners Portfolio, Goldman Sachs Variable
Insurance Trust International Equity, Goldman Sachs Variable Insurance Trust
Global Income, Goldman Sachs Variable Insurance Trust CORE Small Cap Equity and
Goldman Sachs Variable Insurance Trust Mid Cap Value (formerly Goldman Sachs
Variable Insurance Trust Mid Cap Equity) (the Portfolios). The assets of each
portfolio are held separate from the assets of the other portfolios and each has
different investment objectives and policies.

                                      F-69

<PAGE>   141

Each portfolio operates separately and the gains or losses in one portfolio have
no effect on the investment performance of the other portfolios.

INVESTMENT VALUATION

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

INVESTMENT TRANSACTIONS

Investment transactions are accounted for on the trade date (date the order to
buy or sell is executed) and dividend income (including capital gain
distributions) are recorded on the ex-dividend date. The cost of investments
sold was determined using the average cost method prior to 1998. Effective
January 1, 1998, the Variable Account changed its method of calculating the cost
of investments sold from the average cost method to the first in, first out
method (FIFO). Management believes FIFO better matches contractholder and
sub-account investment activity. This change had no impact on the results of
operations for 1998 or prior years, and no impact on the unit value reported
within each of the sub-accounts. Management also believes it would be
impractical to calculate the cumulative effect of this change on previously
reported realized and unrealized gains and losses; however, during 1998 the
change increased realized losses by $44,175 and increased unrealized
appreciation by the same amount.

FEDERAL INCOME TAXES

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


NOTE 3 - CHARGES AND EXPENSES

National Life deducts a daily charge from the Variable Account based on an
annual rate of 1.4% of each sub-account's net asset value as partial
compensation for administration services provided and for National Life's
assumption of mortality and expense risks. The mortality risk assumed is that
the insureds under the contracts may die sooner than anticipated. The expense
risk assumed is that expenses incurred in issuing and administering the
contracts may exceed expected levels.

A contract rider providing certain contract benefit guarantees is available.
Contract charges are deducted annually from each contractholder's accumulated
account value for the insurance protection provided and are remitted to National
Life.

The underlying variable annuity contracts are subject to deferred sales charges.
Net premiums paid are subject to these charges if withdrawn within seven years
of the date of premium deposit.

Contract values under $50,000 are assessed an annual fee.

   NOTE 6 - DISTRIBUTION OF NET INCOME

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

NOTE 7 - DIVERSIFICATION REQUIREMENTS

Under the provisions of Section 817(h) of the Internal Revenue Code (IRC), a
variable annuity contract, other than a contract issued in connection with
certain types of employee benefit plans, will not be treated as a variable
annuity contract for federal income tax purposes for any period for which the
investments of the segregated asset account on which the contract is based are
not adequately diversified. The IRC provides that the adequately diversified
requirement may be met if the underlying investments satisfy either a statutory
safe harbor test or diversification requirements set forth in regulations issued
by the Secretary of the Treasury.

National Life believes that the Variable Account satisfies the current
requirements of the regulations, and it intends that the Variable Account will
continue to meet such requirements.

Item 28. Indemnification

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

         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>   151
         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

       With reference to the Post-Effective Amendment No. 6 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 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 existing 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. 6 to the N-4 Registration Statement and to
       the use of my name under the caption "Legal Matters" in the Registration
       Statement.

                                                Sincerely,

                                                Michele S. Gatto
