                        NATIONWIDE LIFE INSURANCE COMPANY

           Modified Single Premium Deferred Variable Annuity Contracts
             Issued by Nationwide Life Insurance Company through its
                        Nationwide Variable Account -10

                    The date of this prospectus is October 1, 1999.

The contracts described in this prospectus offer a combination of variable
annuity and long-term care insurance benefits. The contracts are intended to:

1.   serve the long-term savings needs of investors; and

2.   provide specific insurance protection against financial loss caused by
     confinement in a nursing home or other long-term care facility.

BECAUSE THE CONTRACT IS SPECIFICALLY DESIGNED FOR INVESTORS ALSO SEEKING
LONG-TERM CARE INSURANCE BENEFITS, THE CONTRACT MAY NOT BE APPROPRIATE FOR
INVESTORS SOLELY INTERESTED IN A VARIABLE ANNUITY. INVESTORS SHOULD CAREFULLY
CONSIDER THE COSTS AND BENEFITS OF THE CONTRACT WITH THEIR INVESTMENT OR
FINANCIAL ADVISER BEFORE PURCHASING THE CONTRACT.


The contract issued with this prospectus consists of two components: variable
annuity benefits and long-term care/disability insurance benefits. The
information in this prospectus describes only information you should know about
the variable annuity provisions of the contract unless stated otherwise.
Investors should read this prospectus in conjunction with the contract and other
material provided which discusses the long-term care/disability insurance
benefits of the contract before purchasing the contract. Please read this
prospectus and keep it for future reference.

The expenses shown above are deducted by the underlying mutual fund before it
provides Nationwide with the daily net asset value. Nationwide then deducts
applicable variable account charges from the net asset value to calculate the
unit value of the corresponding sub-account. The management fees and other
expenses are more fully described in the prospectus for each underlying mutual
fund. Information relating to the underlying mutual funds was provided by the
underlying mutual funds and not independently verified by Nationwide.

Some underlying mutual funds are subject to fee waivers and expense
reimbursements. The following chart shows what the expenses would have been for
such funds without fee waivers and expense reimbursements.

</TABLE>

Minimum subsequent purchase payments to the annuity portion of the contract must
be at least $1,000 (see "Operation of the Contract").

Guaranteed Term Options

Guaranteed Term Options are separate investment options under the contract. The
minimum amount that may be allocated to any Guaranteed Term Option is $1,000.

CHARGES AND EXPENSES

Nationwide deducts a Mortality and Expense Risk Charge equal to an annual rate
of 1.40% of the daily net assets of the variable account. Nationwide assesses
this charge in return for bearing certain mortality and expense risks.

Nationwide does not deduct a sales charge from purchase payments upon allocation
into the annuity portion of the contract. However, Nationwide may deduct a CDSC
if any amount is withdrawn from the annuity portion of the contract. The CDSC
reimburses Nationwide for sales expenses incurred in the sale of the contracts.
The amount of the CDSC will not exceed 8% of purchase payments surrendered.

ANNUITY PAYMENTS

Annuity payments begin on the annuitization date. The payments will be based on
the annuity payment option chosen at the time of application (see "Annuity
Payment Options").

TAXATION

Nationwide will charge against the contract any premium taxes levied by any
governmental authority (see "Federal Tax Considerations" and "Premium Taxes").


RIGHT TO REVOKE/FREE LOOK PERIOD

Contract owners may return the contract for any reason during the underwriting
and free look periods (which may be as long as 120 days after receipt of a
completed application). All revocation requests must be in writing and sent to
Nationwide's home office. Upon a valid revocation request, Nationwide will
refund the contract value and the premium paid for long-term care/disability
insurance benefits without deduction for any sales charges or administration
fees as of the date of cancellation.


FINANCIAL STATEMENTS

Financial statements for Nationwide are located in the Statement of Additional
Information. A current Statement of Additional Information may be obtained,
without charge, by contacting Nationwide's home office at the telephone number
listed on page 2 of this prospectus.

NATIONWIDE LIFE INSURANCE COMPANY

Nationwide is a provider of life insurance, annuities and retirement products.
It is admitted to do business in all states, the District of Columbia and Puerto
Rico.


                                       13
<PAGE>   16


NATIONWIDE ADVISORY SERVICES, INC.

The contracts are distributed by the general distributor, Nationwide Advisory
Services, Inc. ("NAS"), Three Nationwide Plaza, Columbus, Ohio 43215. NAS is a
wholly owned subsidiary of Nationwide Life Insurance Company.

INVESTING IN THE CONTRACT

THE VARIABLE ACCOUNT AND UNDERLYING MUTUAL FUNDS

Nationwide Variable Account -10 is a separate account that invests in the
underlying mutual funds listed in Appendix A. Nationwide established the
variable account on March 31, 1999 pursuant to Ohio law. Although the variable
account is registered with the SEC as a unit investment trust pursuant to the
Investment Company Act of 1940 ("1940 Act"), the SEC does not supervise the
management of Nationwide or the variable account.

Income, gains, and losses credited to, or charged against, the variable account
reflect the variable account's investment experience and not the investment
experience of Nationwide's other assets. The variable account's assets are held
separately from Nationwide's assets and are not chargeable with liabilities
incurred in any other business of Nationwide. Nationwide is obligated to pay all
amounts promised to contract owners under the contracts.

The variable account is divided into sub-accounts. Nationwide uses the assets of
each sub-account to buy shares of the underlying mutual funds based on contract
owner instructions.

Each underlying mutual fund's prospectus contains more detailed information
about that fund. Prospectuses for the underlying mutual funds should be read in
conjunction with this prospectus.

Underlying mutual funds in the variable account are NOT publicly traded mutual
funds. They are only available as investment options in variable life insurance
policies or variable annuity contracts issued by life insurance companies, or in
some cases, through participation in certain qualified pension or retirement
plans.

The investment advisers of the underlying mutual funds may manage publicly
traded mutual funds with similar names and investment objectives. However, the
underlying mutual funds are NOT directly related to any publicly traded mutual
fund. Contract owners should not compare the performance of a publicly traded
fund with the performance of underlying mutual funds participating in the
variable account. The performance of the underlying mutual funds could differ
substantially from that of any publicly traded funds.

Voting Rights

Contract owners who have allocated assets to the underlying mutual funds are
entitled to certain voting rights. Nationwide will vote contract owner shares at
special shareholder meetings based on contract owner instructions. However, if
the law changes and Nationwide is allowed to vote in its own right, it may elect
to do so.

Contract owners with voting interests in an underlying mutual fund will be
notified of issues requiring the shareholders' vote as soon as possible before
the shareholder meeting. Notification will contain proxy materials and a form
with which to give Nationwide voting instructions. Nationwide will vote shares
for which no instructions are received in the same proportion as those that are
received.

The number of shares which a contract owner may vote is determined by dividing
the cash value of the amount they have allocated to an underlying mutual fund by
the net asset value of that underlying mutual fund. Nationwide will designate a
date for this determination not more than 90 days before the shareholder
meeting.

Material Conflicts

The underlying mutual funds may be offered through separate accounts of other
insurance companies, as well as through other separate accounts of Nationwide.
Nationwide does not anticipate any disadvantages to this. However, it is
possible that a conflict may arise between the interests of the variable account
and one or more of the other separate accounts in which these underlying mutual
funds participate.


                                       14
<PAGE>   17

Material conflicts may occur due to a change in law affecting the operations of
variable life insurance policies and variable annuity contracts, or differences
in the voting instructions of the contract owners and those of other companies.
If a material conflict occurs, Nationwide will take whatever steps are necessary
to protect contract owners and variable annuity payees, including withdrawal of
the variable account from participation in the underlying mutual fund(s)
involved in the conflict.

Substitution of Securities

Nationwide may substitute, eliminate, or combine shares of underlying mutual
funds for shares already purchased or to be purchased in the future if either of
the following occurs:

     1)   shares of a current underlying mutual fund are no longer available for
          investment; or

     2)   further investment in an underlying mutual fund is inappropriate.

No substitution, elimination, or combination of shares may take place without
the prior approval of the SEC and state insurance departments.

GUARANTEED TERM OPTIONS

Guaranteed Term Options are separate investment options under the contract. A
Guaranteed Term Option prospectus must be read along with this prospectus. The
minimum amount that may be allocated to a Guaranteed Term Option is $1,000.
Allocations to the Guaranteed Term Options are not subject to variable account
charges.

Guaranteed Term Options provide a guaranteed rate of interest over four
different maturity durations: three (3), five (5), seven (7) or ten (10) years.
The guaranteed term may last for up to 3 months beyond the 3, 5, 7, or 10 year
period since every guaranteed term will end on the final day of a calendar
quarter.

For the duration selected, Nationwide will declare a guaranteed interest rate.
That rate will be credited to amounts allocated to the Guaranteed Term Option
unless a distribution is taken before the maturity date. If a distribution
occurs before the maturity date, the amount distributed will be subject to a
market value adjustment. A market value adjustment can increase or decrease the
amount distributed depending on current interest rate fluctuations. No market
value adjustment will be applied if Guaranteed Term Option allocations are held
to maturity.

Because a market value adjustment can affect the value of a distribution, its
effects should be carefully considered before surrendering or transferring from
Guaranteed Term Options. When actual interest rates are higher than the
guaranteed rate, a market value adjustment would reduce the value of the amount
distributed. When actual interest rates are lower than the guaranteed rate, the
value of the amount distributed would increase.

Guaranteed Term Options are available only during the accumulation phase of a
contract. They are not available after the annuitization date. In addition,
Guaranteed Term Options are not available for use with asset rebalancing, Dollar
Cost Averaging, or systematic withdrawals.

Guaranteed Term Options may not be available in every state.

THE FIXED ACCOUNT

The fixed account is an investment option that is funded by assets of
Nationwide's general account. The general account contains all of Nationwide's
assets other than those in other Nationwide separate accounts. It is used to
support Nationwide's annuity and insurance obligations and may contain
compensation for mortality risks. The general account is not subject to the same
laws as the variable account and the SEC has not reviewed material in this
prospectus relating to the fixed account. However, information relating to the
fixed account is subject to federal securities laws relating to accuracy and
completeness of prospectus disclosure.

Purchase payments will be allocated to the fixed account by election of the
contract owner.

The investment income earned by the fixed account will be allocated to the
contracts at varying guaranteed interest rate(s) depending on


                                       15
<PAGE>   18

the following categories of fixed account allocations:

     -    New Money Rate - The rate credited on the fixed account allocation
          when the contract is purchased or when subsequent purchase payments
          are made. Subsequent purchase payments may receive different New Money
          Rates than the rate when the contract was issued, since the New Money
          Rate is subject to change based on market conditions.

     -    Variable Account to Fixed Rate - Allocations transferred from any of
          the underlying investment options in the variable account to the fixed
          account may receive a different rate. The rate may be lower than the
          New Money Rate. There may be limits on the amount and frequency of
          movements from the variable account to the fixed account.

     -    Renewal Rate - The rate available for maturing fixed account
          allocations which are entering a new guarantee period. The contract
          owner will be notified of this rate in a letter issued with the
          quarterly statements when any of the money in the contract owner's
          fixed account matures. At that time, the contract owner will have an
          opportunity to leave the money in the fixed account and receive the
          Renewal Rate or the contract owner can move the money to any of the
          other underlying mutual fund options.

     -    Dollar Cost Averaging Rate - From time to time, Nationwide may offer a
          more favorable rate for an initial purchase payment into a new
          contract when used in conjunction with a Dollar Cost Averaging
          program.


All of these rates are subject to change on a daily basis; however, once money
is allocated to the fixed account, the interest rate assigned is guaranteed
until the end of the calendar quarter during the 12 month anniversary in which
the fixed account allocation occurs.


Credited interest rates are annualized rates - the effective yield of interest
over a one-year period. Interest is credited to each contract on a daily basis.
As a result, the credited interest rate is compounded daily to achieve the
stated effective yield.

The guaranteed rate for any purchase payment will be effective for not less than
twelve months. Nationwide guarantees that the rate will not be less than 3.0%
per year.

Any interest in excess of 3.0% will be credited to fixed account allocations at
Nationwide's sole discretion. The contract owner assumes the risk that interest
credited to fixed account allocations may not exceed the minimum guarantee of
3.0% for any given year.

Nationwide guarantees that the fixed account contract value will not be less
than the amount of the purchase payments allocated to the fixed account, plus
interest credited as described above, less any applicable charges including
CDSC.

STANDARD CHARGES AND DEDUCTIONS

MORTALITY AND EXPENSE RISK CHARGE

Nationwide deducts a Mortality and Expense Risk Charge from the variable
account. This amount is computed on a daily basis, and is equal to an annual
rate of 1.40% of the daily net assets of the variable account.

The mortality risk charge compensates Nationwide for guaranteeing the annuity
rate of the contracts. This guarantee ensures that the annuity rates will not
change regardless of the death rates of annuity payees or the general
population.

The expense risk charge compensates Nationwide for guaranteeing that
administration charges will not increase regardless of actual expenses.

If the Mortality and Expense Risk Charge is insufficient to cover actual
expenses, the loss is borne by Nationwide.

CONTINGENT DEFERRED SALES CHARGE

No sales charge deduction is made from the purchase payments when amounts are
allocated into the contract. However, if any part of the annuity portion of the
contract is surrendered, Nationwide will deduct a CDSC. The CDSC


                                       16
<PAGE>   19

will not exceed 8% of purchase payments surrendered.

The CDSC is calculated by multiplying the applicable CDSC percentage (noted
below) by the amount of purchase payments surrendered.

For purposes of calculating the CDSC, surrenders are considered to come first
from the oldest purchase payment made to the contract, then the next oldest
purchase payment, and so forth. For tax purposes, a surrender is usually treated
as a withdrawal of earnings first.

The CDSC applies as follows:

- ------------------------------------------------
</TABLE>

The CDSC is used to cover sales expenses, including commissions paid (maximum of
8.5% of purchase payments), production of sales material, and other promotional
expenses. If expenses are greater than the CDSC, the shortfall will be made up
from Nationwide's general assets, which may indirectly include portions of the
variable account charges, since Nationwide may generate a profit from these
charges.

Contract owners taking withdrawals before age 59 1/2 may be subject to a 10% tax
penalty. In addition, all or a portion of the withdrawal may be subject to
federal income taxes (see "Natural Persons as Contract Owners").

Waiver of Contingent Deferred Sales Charge

Each contract year, the contract owner may withdraw without a CDSC the lesser
of:

   1)  10% of purchase payments made to the annuity portion of the contract
       (less any purchase payment previously withdrawn from the annuity portion
       of the contract); or

   2)   10% of the value of the annuity portion of the contract.

This CDSC-free privilege is non-cumulative. Free amounts not taken during any
given contract year cannot be taken as free amounts in a subsequent contract
year.

In addition, no CDSC will be deducted:

   (1)  upon annuitization;

   (2)  upon payment of a death benefit; or

   (3)  from any values which have been held under a contract for at least 13
        years.

No CDSC applies to transfers among sub-accounts or between or among the
Guaranteed Term Options, the fixed account, or the variable account. Nationwide
may waive the CDSC if a contract described in this prospectus is exchanged for
another Nationwide contract (or a contract of any of its affiliated insurance
companies). A CDSC may apply to the contract received in the exchange.

The CDSC will not be eliminated if to do so would be unfairly discriminatory or
prohibited by state law.

PREMIUM TAXES

Nationwide will charge against the contract value any premium taxes levied by a
state or other government entity. Premium tax rates currently range from 0% to
3.5%. This range is subject to change. The method used to assess premium tax
will be determined by Nationwide at its sole discretion in compliance with state
law.

If applicable, Nationwide will deduct premium taxes from the contract either at:

   (1)  the time the contract is surrendered;

   (2)  annuitization; or

   (3)  such earlier date as Nationwide becomes subject to premium taxes.

Premium taxes may be deducted from death benefit proceeds.

CONTRACT OWNERSHIP

The contract owner has all rights under the contract. Purchasers who name
someone other than themselves as the contract owner will have no rights under
the contract.

Contract owners may name a new contract owner at any time before the
annuitization date. Any change of contract owner automatically revokes any prior
contract owner designation. Changes in contract ownership may result in federal
income taxation and may be subject to state and federal gift taxes.

A change in contract ownership must be submitted in writing, signed by the
contract owner and the person designated as the new contract owner, and recorded
at Nationwide's home office. Nationwide may require a signature guarantee. Once
recorded, the change will be effective as of the date signed. However, the
change will not affect any payments made or actions taken by Nationwide before
it was recorded.

The contract owner may also request a change in the annuitant, joint owner,
beneficiary, or contingent beneficiary before the annuitization date. These
changes must be:

     -  on a Nationwide form;

     -  signed by the contract owner; and

     -  received at Nationwide's home office before the annuitization date.

Nationwide must review and approve any change requests. Any change of the
annuitant is subject to underwriting and approval by Nationwide. If the contract
owner is not a natural person and there is a change of the annuitant,
distributions will be made as if the contract owner died at the time of the
change.

On the annuitization date, the annuitant will become the contract owner.

JOINT OWNERSHIP

Joint owners each own an undivided interest in the contract. Contract owners can
name a joint owner at any time before annuitization subject to the following
conditions:

     -  Joint owners must be spouses at the time joint ownership is requested,
        unless state law requires Nationwide to allow non-spousal joint
        owners.

     -  The exercise of any ownership right in the contract will generally
        require a written request signed by both joint owners.

     -  An election in writing signed by both contract owners must be made to
        authorize Nationwide to allow the exercise of ownership rights
        independently by either joint owner.

     -  Nationwide will not be liable for any loss, liability, cost, or
        expense for acting in accordance with the instructions of either joint
        owner.

ANNUITANT

The annuitant is the person who will receive annuity payments and upon whose
continuation of life any annuity payment involving life contingencies depends.
This person must be age 85 or younger at the time of contract issuance, unless
Nationwide approves a request for an annuitant of greater age. The annuitant may
be changed before the annuitization date subject to underwriting and approval by
Nationwide.

BENEFICIARY AND CONTINGENT BENEFICIARY

The beneficiar(ies) is the person(s) who is entitled to the death benefit if the
annuitant dies before the annuitization date and there is no joint owner. The
contingent beneficiar(ies) is the person(s) who is entitled to the death benefit
if there is no surviving joint owner and no beneficiary survives the annuitant.
If no contingent beneficiary survives the annuitant, all rights and interests
will vest in the last surviving contract owner's estate.

The contract owner can name more than one beneficiary or contingent beneficiary.
Multiple beneficiaries or contingent beneficiaries will share the death benefit
equally, unless otherwise specified.

The contract owner may change the beneficiary or contingent beneficiary during
the annuitant's lifetime by submitting a written request to Nationwide. Once
recorded, the change will be


                                       18
<PAGE>   21


effective as of the date it was signed, whether or not the annuitant was living
at the time it was recorded. The change will not affect any action taken by
Nationwide before the change was recorded.

OPERATION OF THE CONTRACT


PRICING OF THE MINIMUM INITIAL PURCHASE PAYMENT

The minimum initial annuity purchase payment allocated to the sub-accounts as
shown on the completed application will be transferred to the NSAT Money Market
Fund within 2 business days of receipt until the end of the period in which the
contract owner may cancel the contract (the underwriting and free look periods).
Such a period may last up to 120 days after receipt of a completed application
(a maximum of 90 days for the underwriting period and a 30 day free look
period). In addition, if the underwriting period cannot be completed within 90
days for any reason, the annuity contract value, plus premium paid for the
long-term care insurance benefits will be returned to the purchaser.

While attempting to complete an incomplete application, Nationwide may retain
the initial purchase payment for up to 5 business days. If the application is
not completed within 5 business days, the prospective purchaser will be informed
of the reason for the delay. All purchase payments, including premium for the
long-term care insurance will be returned unless the prospective purchaser
specifically allows Nationwide to hold the purchase payment until the
application is completed.

Upon the expiration of the underwriting and free look periods, the initial
purchase payment allocated to the NSAT Money Market Fund will be transferred,
the same business day, to sub-accounts indicated on the application and
purchased at net asset value.

PRICING OF SUBSEQUENT PURCHASE PAYMENTS

Minimum subsequent purchase payments may only be made to the annuity portion of
the contract and must be at least $1,000. Subsequent purchase payments will be
priced based on the next available accumulation unit value calculated after the
payment is received. The cumulative total of all purchase payments under
contracts on the life of any one annuitant cannot exceed $1,000,000 without
Nationwide's prior consent.


Subsequent purchase payments may not be made during the underwriting and free
look periods. In addition, subsequent purchase payments are not permitted for
contracts issued in the State of Oregon and may not be permitted in other states
under certain circumstances.

GUARANTEED TERM OPTIONS

Guaranteed Term Options are separate investment options under the contract. The
minimum amount that may be allocated to a Guaranteed Term Option is $1,000.


WHEN PURCHASE PAYMENTS WILL NOT BE PRICED


Purchase payments will not be priced when the New York Stock Exchange is closed
or on the following nationally recognized holidays:

   New Year's Day                   Independence Day
   Martin Luther King, Jr. Day      Labor Day
   Presidents' Day                  Thanksgiving
   Good Friday                      Christmas
   Memorial Day

Nationwide also will not price purchase payments if:

     (1)  trading on the New York Stock Exchange is restricted;

     (2)  an emergency exists making disposal or valuation of securities held in
          the variable account impracticable; or

     (3)  the SEC, by order, permits a suspension or postponement for the
          protection of security holders.

Rules and regulations of the SEC will govern as to when the conditions described
in (2) and (3) exist. If Nationwide is closed on days when the New York Stock
Exchange is open, contract value may be affected since the contract owner would
not have access to their account.

ALLOCATION OF PURCHASE PAYMENTS


Nationwide allocates purchase payments to sub-accounts (after the expiration of
the underwriting and free look periods), the fixed


                                       19
<PAGE>   22


account and/or Guaranteed Term Options as instructed by the contract owner.
Shares of the underlying mutual funds allocated to the sub-accounts are
purchased at net asset value (as of the date the purchase payments are applied
to the sub-accounts), then converted into accumulation units.


DETERMINING THE VALUE OF THE ANNUITY PORTION OF THE CONTRACT

The value of the annuity portion of the contract is the sum of:

     1)  the value of amounts allocated to the sub-accounts of the variable
         account;

     2)  amounts allocated to the fixed account; and

     3)  amounts allocated to a Guaranteed Term Option.

If part or all of the value of the annuity portion of the contract is
surrendered, or charges are assessed against the value of the annuity portion of
the contract, Nationwide will deduct a proportionate amount from each
sub-account, the fixed account and any Guaranteed Term Option based on current
cash values.

Determining Variable Account Value - Valuing an Accumulation Unit

Purchase payments or transfers allocated to sub-accounts are accounted for in
accumulation units. Accumulation unit values (for each sub-account) are
determined by calculating the net investment factor for the underlying mutual
funds for the current valuation period and multiplying that result with the
accumulation unit values determined on the previous valuation period.

Nationwide uses the net investment factor as a way to calculate the investment
performance of a sub-account from valuation period to valuation period. For each
sub-account, the net investment factor shows the investment performance of the
underlying mutual fund in which a particular sub-account invests, including the
charges assessed against that sub-account for a valuation period.

The net investment factor for any particular sub-account is determined by
dividing (a) by (b), and then subtracting (c) from the result, where:

   (a)  is:

        (1)  the net asset value of the underlying mutual fund as of the end
             of the current valuation period; and

        (2)  the per share amount of any dividend or income distributions made
             by the underlying mutual fund (if the ex-dividend date occurs
             during the current valuation period).

   (b) is the net asset value of the underlying mutual fund determined as of the
       end of the preceding valuation period.

   (c) is a factor representing the daily variable account charges. The factor
       is equal to an annual rate of 1.40% of the daily net assets of the
       variable account.

Based on the change in the net investment factor, the value of an accumulation
unit may increase or decrease. Changes in the net investment factor may not be
directly proportional to changes in the net asset value of the underlying mutual
fund shares because of the deduction of variable account charges.

Though the number of accumulation units will not change as a result of
investment experience, the value of an accumulation unit may increase or
decrease from valuation period to valuation period.

Determining Fixed Account Value

Nationwide determines the value of the fixed account by:

          1)  adding all amounts allocated to the fixed account, minus amounts
              previously transferred or withdrawn; and

          2)  adding any interest earned on the amounts allocated.

Determining the Guaranteed Term Option Value

Nationwide determines the value of a Guaranteed Term Option by:

          1)  adding all amounts allocated to any Guaranteed Term Option, minus
              amounts previously transferred or withdrawn (which may be subject
              to a market value adjustment);


                                       20
<PAGE>   23

          2)  adding any interest earned on the amounts allocated to any
              Guaranteed Term Option; and

          3)  subtracting charges deducted in accordance with the annuity
              portion of the contract.


TRANSFERS

Transfer Requests

No transfer requests of any kind will be allowed during the underwriting and
free look periods.

After the expiration of the underwriting and free look periods, Nationwide will
accept transfer requests in writing or, in those states that allow them, over
the telephone. Nationwide will use reasonable procedures to confirm that
telephone instructions are genuine and will not be liable for following
telephone instructions that it reasonably determines to be genuine. Nationwide
may withdraw the telephone exchange privilege upon 30 days written notice to
contract owners.

After annuitization, transfers may only be made on an anniversary of the
annuitization date.


Transfers from the Fixed Account to the Variable Account or a Guaranteed Term
Option

Fixed account allocations may be transferred to the variable account or to a
Guaranteed Term Option only upon reaching the end of an interest rate guarantee
period. Normally, Nationwide will permit 100% of such fixed account allocations
to be transferred to the variable account or to a Guaranteed Term Option;
however Nationwide may, under certain economic conditions and at its discretion,
limit the maximum transferable amount. Under no circumstances will the maximum
transferable amount be less than 10% of the fixed account allocation reaching
the end of an interest rate guarantee period. Transfers of the fixed account
allocations must be made within 45 days after reaching the end of an interest
rate guarantee period.


Amounts transferred to the variable account will be priced at the accumulation
unit value next determined after the transfer request is received.


Contract owners who use Dollar Cost Averaging may transfer from the fixed
account to the variable account (but not to Guaranteed Term Options) under the
terms of that program (see "Dollar Cost Averaging").


Transfers from a Guaranteed Term Option

Transfers from a Guaranteed Term Option prior to maturity are subject to a
market value adjustment.

Transfers from Sub-Account to Sub-Account

Transfers may be made from sub-account to sub-account, however, no change may be
made that would result in an amount less than 1% of the purchase payment being
allocated to any sub-account. Certain transactions may be subject to conditions
imposed by the underlying mutual funds, as well as those set forth in the
contract.

Market Timing Firms

Some contract owners may use market timing firms or other third parties to make
transfers on their behalf. Generally, in order to take advantage of perceived
market trends, market timing firms will submit transfer or exchange requests on
behalf of multiple contract owners at the same time. Sometimes this can result
in unusually large transfers of funds. These large transfers might interfere
with the ability of Nationwide or the underlying mutual fund to process
transactions. This can potentially disadvantage contract owners not using market
timing firms. To avoid this, Nationwide may modify transfer and exchange rights
of contract owners who use market timing firms (or other third parties) to
transfer or exchange funds on their behalf.

To protect contract owners, Nationwide may refuse exchange and transfer
requests:

     -    submitted by any agent acting under a power of attorney on behalf of
          more than one contract owner; or

     -    submitted on behalf of individual contract owners who have executed
          pre-authorized exchange forms which are submitted by market timing
          firms (or other third parties) on behalf of more than one contract
          owner at the same time.



                                       21
<PAGE>   24


     -    The exchange and transfer rights of individual contract owners will
          not be modified in any way when instructions are submitted directly by
          the contract owner, or by the contract owner's representative (as
          authorized by the execution of a valid Nationwide Limited Power of
          Attorney Form).

Nationwide will not restrict exchange rights unless Nationwide believes it to be
necessary for the protection of all contract owners.


Transfers to the Fixed Account

Variable account allocations may be transferred to the fixed account at any
time. Normally, Nationwide will not restrict transfers from the variable account
to the fixed account; however, Nationwide may establish a maximum transfer limit
from the variable account to the fixed account. Except as noted below, under no
circumstances will the transfer limit be less than 10% of the current value of
the variable account, less any transfers made in the 12 months preceding the
date the transfer is requested, but not including transfers made prior to the
imposition of the transfer limit. However, where permitted by state law,
Nationwide reserves the right to refuse transfers or purchase payments to the
fixed account (whether from the variable account or a Guaranteed Term Option)
when the fixed account value is greater than or equal to 30% of the value of the
annuity portion of the contract at the time the purchase payment is made or the
transfer is requested.

Interest Rate Guarantee Period

The interest rate guarantee period is the period of time that the fixed account
interest rate is guaranteed to remain the same. Within 45 days of the end of an
interest rate guarantee period, transfers may be made from the fixed account to
the variable account or to the Guaranteed Term Options. Nationwide will
determine the amount that may be transferred and will declare this amount at the
end of the guarantee period. This amount will not be less than 10% of the amount
in the fixed account that is maturing.

For new purchase payments allocated to the fixed account, or transfers to the
fixed account from the variable account or to a Guaranteed Term Option, this
period begins on the date of deposit or transfer and ends on the one year
anniversary of the deposit or transfer. The guaranteed interest rate period may
last for up to 3 months beyond the 1 year anniversary because guaranteed terms
end on the last day of a calendar quarter.

The interest rate guarantee period does not in any way refer to interest rate
crediting practices connected with Guaranteed Term Options.

During an interest rate guarantee period, transfers cannot be made from the
fixed account, and amounts transferred to the fixed account must remain on
deposit.

SURRENDER (REDEMPTION)

Contract owners may surrender some or all of the contract value in the annuity
portion of the contract before the earlier of the annuitization date or the
annuitant's death. Surrender requests must be in writing and Nationwide may
require additional information. Nationwide may require a signature guarantee.

Nationwide will pay any amounts surrendered from the sub-accounts within 7 days.
However, Nationwide may suspend or postpone payment when it is unable to price a
purchase payment or transfer.

PARTIAL SURRENDERS (PARTIAL REDEMPTIONS)

Nationwide will surrender accumulation units from the sub-accounts and an amount
from the fixed account and Guaranteed Term Options. The amount withdrawn from
each investment option will be in proportion to the value in each option at the
time of the surrender request, unless otherwise instructed by the contract
owner.

A CDSC may apply. The contract owner may take the CDSC from either:

     a)   the amount requested; or

     b)   the value of the annuity portion of the contract remaining after the
          contract owner has received the amount requested.

If the contract owner does not make a specific election, any applicable CDSC
will be taken


                                       22
<PAGE>   25


from the value in the annuity portion of the contract remaining after the
contract owner has received the amount requested.

FULL SURRENDERS (FULL REDEMPTIONS)

The contract value in the annuity portion of the contract upon full surrender
may be more or less than the total of all purchase payments made to the
contract. The value in the annuity portion of the contract will reflect variable
account charges, underlying mutual fund charges and the investment performance
of the underlying mutual funds. A CDSC may apply.

ASSIGNMENT

Contract rights are personal to the contract owner and may not be assigned
without Nationwide's written consent.

A contract owner may assign some or all rights under the contract. An assignment
must occur before annuitization while the annuitant is alive. Once proper notice
of assignment is recorded by Nationwide's home office, the assignment will
become effective as of the date the written request was signed.

Nationwide is not responsible for the validity or tax consequences of any
assignment. Nationwide is not liable for any payment or settlement made before
the assignment is recorded. Assignments will not be recorded until Nationwide
receives sufficient direction from the contract owner and the assignee regarding
the proper allocation of contract rights.

Amounts pledged or assigned under the annuity provisions of the contract will be
treated as distributions and will be included in gross income to the extent that
the cash value exceeds the investment in the annuity portion of the contract for
the taxable year in which it was pledged or assigned. Amounts assigned may be
subject to a tax penalty equal to 10% of the amount included in gross income.

Assignment of the entire contract value may cause the portion of the contract
value exceeding 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.

CONTRACT OWNER SERVICES


Asset rebalancing, dollar cost averaging and systematic withdrawals are not
available during the underwriting and free look periods.


ASSET REBALANCING

Asset rebalancing is the automatic reallocation of values to the sub-accounts on
a predetermined percentage basis. Asset rebalancing is not available for assets
held in the fixed account or the Guaranteed Term Options.
Requests for asset rebalancing must be on a Nationwide form.

Asset rebalancing occurs every three months or on another frequency if permitted
by Nationwide. If the last day of the three-month period falls on a Saturday,
Sunday, recognized holiday, or any other day when the New York Stock Exchange is
closed, asset rebalancing will occur on the next business day.

Contract owners should consult a financial adviser to discuss the use of asset
rebalancing.

Nationwide reserves the right to stop establishing new asset rebalancing
programs. Nationwide also reserves the right to assess a processing fee for this
service.

DOLLAR COST AVERAGING

Dollar Cost Averaging is a long-term transfer program that allows you to make
regular, level investments over time. It involves the automatic transfer of a
specified amount from the fixed account and/or certain sub-accounts into other
sub-accounts. Nationwide does not guarantee that this program will result in
profit or protect contract owners from loss.

Contract owners direct Nationwide to automatically transfer specified amounts
from the fixed account and the following underlying mutual funds: Federated
Insurance Series - Federated Quality Bond Fund II, Fidelity VIP High Income
Portfolio, NSAT Government Bond Fund, NSAT Nationwide High Income Bond Fund, and
NSAT Money Market Fund to any other underlying mutual fund. Dollar Cost
Averaging transfers may not be directed to


                                       23
<PAGE>   26

Guaranteed Term Options. The minimum monthly transfer is $100.

Transfers occur monthly or on another frequency if permitted by Nationwide.
Nationwide will process transfers until either the value in the originating
investment option is exhausted, or the contract owner instructs Nationwide in
writing to stop the transfers.

Dollar Cost Averaging from the Fixed Account

Transfers from the fixed account must be equal to or less than 1/30th of the
fixed account value at the time the program is requested. A Dollar Cost
Averaging program which transfers amounts from the fixed account to the variable
account is not the same as an Enhanced Rate Dollar Cost Averaging program.
Contract owners that wish to utilize Dollar Cost Averaging from the fixed
account should first inquire whether any Enhanced Rate Dollar Cost Averaging
programs are available.

Nationwide reserves the right to stop establishing new Dollar Cost Averaging
programs. Nationwide also reserves the right to assess a processing fee for this
service.

Enhanced Rate Dollar Cost Averaging

Nationwide may, from time to time, offer Enhanced Rate Dollar Cost Averaging
programs in which contract owners may allocate all or a portion of their fixed
account assets. Enhanced Rate Dollar Cost Averaging programs allow the contract
owner to earn a higher rate of interest on assets allocated to the program than
would be earned on assets in the fixed account. Each enhanced interest rate is
guaranteed for as long as the corresponding program is in effect and applies
only to the assets within that program. Nationwide will process transfers until
either amounts in the Enhanced Rate Dollar Cost Averaging program are exhausted,
or the contract owner instructs Nationwide in writing to stop the transfers. For
these programs only, when a written request to discontinue transfers is
received, Nationwide will automatically transfer the remaining amount in the
program to the NSAT Money Market Fund.

SYSTEMATIC WITHDRAWALS

Systematic withdrawals allow contract owners to receive a specified amount (of
at least $100) on a monthly, quarterly, semi-annual, or annual basis. Requests
for systematic withdrawals and requests to discontinue systematic withdrawals
must be in writing.

The withdrawals will be taken from the sub-accounts and the fixed account
proportionately unless Nationwide is instructed otherwise. Systematic
withdrawals are not available from the Guaranteed Term Options.

Nationwide will withhold federal income taxes from systematic withdrawals unless
otherwise instructed by the contract owner. The Internal Revenue Service may
impose a 10% penalty tax if the contract owner is under age 59 1/2 unless the
contract owner has made an irrevocable election of distributions of
substantially equal payments.

If the contract owner takes systematic withdrawals, the maximum amount that can
be withdrawn annually without a CDSC is the greater of:

     1)  10% of the total of all purchase payments made to the annuity portion
         of the contract as of the withdrawal date;

     2)  any amount withdrawn to meet minimum distribution requirements under
         the Internal Revenue Code; or

     3)  a percentage of the value of the annuity portion of the contract based
         on the contract owner's age, as shown in the table below:

<TABLE>

</TABLE>

The value of the annuity portion of the contract and contract owner's age are
determined as of the date the request for the withdrawal program


                                       24
<PAGE>   27

is recorded by Nationwide's home office. For joint owners, the older joint
owner's age will be used.

If total amounts withdrawn in any contract year exceed the CDSC-free amount
described above, those amounts will only be eligible for the 10% of purchase
payment CDSC-free withdrawal privilege described in the "Waiver of Contingent
Deferred Sales Charge" section. The total amount of CDSC for that contract year
will be determined in accordance with that provision.

The CDSC-free withdrawal privilege for systematic withdrawals is non-cumulative.
Free amounts not taken during any contract year cannot be taken as free amounts
in a subsequent contract year.

Nationwide reserves the right to stop establishing new systematic withdrawal
programs. Nationwide also reserves the right to assess a processing fee for this
service. Systematic withdrawals are not available before the end of the period
that a contract owner can cancel the contract (see "Right to Revoke").

ANNUITY COMMENCEMENT DATE

The annuity commencement date is the date on which annuity payments are
scheduled to begin. The contract owner may change the annuity commencement date
before annuitization. This change must be in writing and approved by Nationwide.

ANNUITIZING THE CONTRACT

ANNUITIZATION DATE

The annuitization date is the date that annuity payments begin. It will be the
first day of a calendar month unless otherwise agreed, and must be at least 2
years after the contract is issued.

ANNUITIZATION

Annuitization is the period during which annuity payments are received. It is
irrevocable once payments have begun. Upon arrival of the annuitization date,
the annuitant must choose:

     (1)  an annuity payment option; and

     (2)  either a fixed payment annuity, variable payment annuity, or an
          available combination.

Nationwide guarantees that each payment under a fixed payment annuity will be
the same throughout annuitization. Under a variable payment annuity, the amount
of each payment will vary with the performance of the underlying mutual funds
chosen by the contract owner.

FIXED PAYMENT ANNUITY

A fixed payment annuity is an annuity where the amount of the annuity payments
remains level.

The first payment under a fixed payment annuity is determined on the
annuitization date on an "age last birthday" basis by:

     1)  deducting applicable premium taxes from the annuity contract value;
         then

     2)  applying the amount of the value of the annuity portion of the
         contract specified by the contract owner to the fixed payment annuity
         table for the annuity payment option elected.

Subsequent payments will remain level unless the annuity payment option elected
provides otherwise. Nationwide does not credit discretionary interest during
annuitization.

VARIABLE PAYMENT ANNUITY

A variable payment annuity is an annuity where the amount of the annuity
payments will vary depending on the performance of the underlying mutual funds
selected.

The first payment under a variable payment annuity is determined on the
annuitization date on an "age last birthday" basis by:

     1)  deducting applicable premium taxes from the annuity contract value;
         then

     2)  applying the amount of the value of the annuity portion of the
         contract specified by the contract owner to the variable payment
         annuity table for the annuity payment option elected.

The dollar amount of the first payment is converted into a set number of annuity
units that will represent each monthly payment. This is


                                       25
<PAGE>   28

done by dividing the dollar amount of the first payment by the value of an
annuity unit as of the annuitization date. This number of annuity units remains
fixed during annuitization.

The second and subsequent payments are determined by multiplying the fixed
number of annuity units by the annuity unit value for the valuation period in
which the payment is due. The amount of the second and subsequent payments will
vary with the performance of the selected underlying mutual funds. Nationwide
guarantees that variations in mortality experience from assumptions used to
calculate the first payment will not affect the dollar amount of the second and
subsequent payments.

Assumed Investment Rate

An assumed investment rate is the percentage rate of return assumed to determine
the amount of the first payment under a variable payment annuity. Nationwide
uses the assumed investment rate of 3.5% to calculate the first annuity payment
and to calculate the investment performance of an underlying mutual fund in
order to determine subsequent payments under a variable payment annuity. An
assumed investment rate is the percentage rate of return required to maintain
level variable annuity payments. Subsequent variable annuity payments may be
more or less than the first payment based on whether actual investment
performance of the underlying mutual funds is higher or lower than the assumed
investment rate of 3.5%.

Value of an Annuity Unit

Annuity unit values for sub-accounts are determined by multiplying the net
investment factor for the valuation period for which the annuity unit is being
calculated by the immediately preceding valuation period's annuity unit value,
and multiplying the result by an interest factor to neutralize the assumed
investment rate of 3.5% per annum built into the variable payment annuity
purchase rate basis in the contracts.

Exchanges among Underlying Mutual Funds

Exchanges among underlying mutual funds during annuitization must be in writing.
Exchanges will occur on each anniversary of the annuitization date.

FREQUENCY AND AMOUNT OF ANNUITY PAYMENTS

Payments are made based on the annuity payment option selected, unless:

     -   the amount to be distributed is less than $5,000, in which case
         Nationwide may make one lump sum payment of the contract value; or

     -   an annuity payment would be less than $50, in which case Nationwide
         can change the frequency of payments to intervals that will result in
         payments of at least $50. Payments will be made at least annually.

ANNUITY PAYMENT OPTIONS

Contract owners must elect an annuity payment option before the annuitization
date. The annuity payment options are:

(1)  LIFE ANNUITY - An annuity payable periodically, but at least annually, for
     the lifetime of the annuitant. Payments will end upon the annuitant's
     death. For example, if the annuitant dies before the second annuity payment
     date, the annuitant will receive only one annuity payment. The annuitant
     will only receive two annuity payments if he or she dies before the third
     annuity payment date, and so on.

(2)  JOINT AND LAST SURVIVOR ANNUITY - An annuity payable periodically, but at
     least annually, during the joint lifetimes of the annuitant and a
     designated second individual. If one of these parties dies, payments will
     continue for the lifetime of the survivor. As is the case under option 1,
     there is no guaranteed number of payments. Payments end upon the death of
     the last surviving party, regardless of the number of payments received.

(3)  LIFE ANNUITY WITH 120 OR 240 MONTHLY PAYMENTS GUARANTEED - An annuity
     payable monthly during the lifetime of the annuitant. If the annuitant dies
     before all of the guaranteed payments have been made, payments will
     continue to the end of the guaranteed period and will be paid to a


                                       26
<PAGE>   29

     designee chosen by the annuitant at the time the annuity payment option was
     elected.

     The designee may elect to receive the present value of the remaining
     guaranteed payments in a lump sum. The present value will be computed as of
     the date Nationwide receives the notice of the annuitant's death.

Not all of the annuity payment options may be available in all states. Contract
owners may request other options before the annuitization date. These options
are subject to Nationwide's approval.

No distribution for the contracts will be made until an annuity payment option
has been elected.

DEATH BENEFITS

DEATH OF CONTRACT OWNER

If the contract owner who is not the annuitant dies before the annuitization
date, the joint owner becomes the contract owner. If no joint owner is named,
the annuitant becomes the contract owner.

Distributions under the contracts will be made pursuant to the "Required
Distributions" provision.

DEATH OF ANNUITANT

If the annuitant who is not the contract owner dies before the annuitization
date, a death benefit is payable to the beneficiary.

If no beneficiaries survive the annuitant, the contingent beneficiary(ies)
receives the death benefit. Contingent beneficiaries will share the death
benefit equally, unless otherwise specified.

If no beneficiaries or contingent beneficiaries survive the annuitant, the
contract owner or the last surviving contract owner's estate will receive the
death benefit.

If the annuitant dies after the annuitization date, any benefit that may be
payable will be paid according to the selected annuity payment option.

DEATH OF CONTRACT OWNER/ANNUITANT

If a contract owner who is also the annuitant dies before the annuitization
date, a death benefit is payable according to the "Death of the Annuitant"
provision.

A joint owner will receive a death benefit if a contract owner/annuitant dies
before the annuitization date.

If the contract owner/annuitant dies after the annuitization date, any benefit
that may be payable will be paid according to the selected annuity payment
option.

HOW THE DEATH BENEFIT IS DETERMINED

The death benefit value is determined as of the date Nationwide receives:

     1)  proper proof of the annuitant's death;

     2)  an election specifying the distribution method; and

     3)  any state required form(s).

The beneficiary may elect to receive the death benefit:

     (1)  in a lump sum;

     (2)  as an annuity; or

     (3)  in any other manner permitted by law and approved by Nationwide.

The beneficiary must notify Nationwide of this election within 60 days of the
annuitant's death.

DEATH BENEFIT PAYMENT

If the annuitant dies at any time prior to the annuitization date, the dollar
amount of the annuity death benefit will be the greater of:

     (1)  the value of the annuity portion of the contract; or

     (2)  the sum of all purchase payments made to the annuity portion of the
          contract, less an adjustment for amounts surrendered.

The adjustment for amounts surrendered will reduce item (2) above in the same
proportion that the value of the annuity portion of the contract was reduced on
the date of the partial surrender.


                                       27

REQUIRED DISTRIBUTIONS

Internal Revenue Code Section 72(s) requires Nationwide to make certain
distributions when a contract owner dies. The following distributions will be
made according to those requirements:

   1)  If any contract owner dies on or after the annuitization date and before
       the entire interest in the contract has been distributed, then the
       remaining interest must be distributed at least as rapidly as the
       distribution method in effect on the contract owner's death.

   2)  If any contract owner dies before the annuitization date, then the entire
       interest in the contract (consisting of either the death benefit or the
       contract value reduced by charges set forth elsewhere in the contract)
       will be distributed within 5 years of the contract owner's death,
       provided however:

       a)  any interest payable to or for the benefit of a natural person
           (referred to herein as a "designated beneficiary"), may be
           distributed over the life of the designated beneficiary or over a
           period not longer than the life expectancy of the designated
           beneficiary. Payments must begin within one year of the contract
           owner's death unless otherwise permitted by federal income tax
           regulations;

       b)  if the designated beneficiary is the surviving spouse of the deceased
           contract owner, the spouse can choose to become the contract owner
           instead of receiving a death benefit. Any distributions required
           under these distribution rules will be made upon that spouse's death.

In the event that the contract owner is NOT a natural person (e.g., a trust or
corporation), then, for purposes of these distribution provisions:

     a)   the death of the annuitant will be treated as the death of a contract
          owner;

     b)   any change of annuitant will be treated as the death of a contract
          owner; and

     c)   in either case, the appropriate distribution will be made upon the
          death or change, as the case may be.

These distribution provisions do not apply to any contract exempt from Section
72(s) of the Internal Revenue Code by reason of Section 72(s)(5) or any other
law or rule.

The designated beneficiary must elect a method of distribution and notify
Nationwide of this election within 60 days of the contract owner's death.

FEDERAL TAX CONSIDERATIONS

FEDERAL INCOME TAXES

Contract owners should consult a financial consultant, legal counsel or tax
adviser to discuss in detail the taxation and the use of the contracts.

Nationwide does not guarantee the tax status of the contracts or any
transactions involving the contracts.

Section 72 of the Internal Revenue Code governs federal income taxation of
annuities in general. That section sets forth different rules for: (1)
Individual Retirement Annuities, including SEP IRAs and Simple IRAs; (2) Roth
IRAs; (3) Tax Sheltered Annuities; and (4) Non-Qualified Contracts.
Non-Qualified contracts are discussed below.

Natural Persons as Contract Owners

The rules applicable to Non-Qualified Contracts provide that a portion of each
annuity payment is excludable from taxable income based on the ratio between the
contract owner's investment in the contract and the expected return on the
contract until the investment has been recovered. Thereafter the entire amount
is includible in income. The maximum amount excludable from income is the
investment in the contract. If the annuitant dies before the entire investment
in the contract has been excluded from income and no additional payments are due
after his or her death, then he or she may be entitled to a deduction for the
balance of the unrecovered investment in the contract on his or her final income
tax return.

                                       28
<PAGE>   31

Distributions before the annuitization date are taxable to the contract owner to
the extent that the cash value of the contract exceeds the contract owner's
investment at the time of the distribution. Distributions, for this purpose,
include partial surrenders, dividends, loans, or any portion of the contract
that is assigned or pledged; or for contracts issued after April 22, 1987, any
portion of the contract transferred by gift. For these purposes, a transfer by
gift may occur upon annuitization if the contract owner and the annuitant are
not the same individual.

In determining the taxable amount of a distribution, all annuity contracts
issued after October 21, 1988 by the same company to the same contract owner
during any 12-month period will be treated as one annuity contract. Additional
limitations on the use of multiple contracts may be imposed by Treasury
Regulations.

Distributions before the annuitization date allocable to a portion of the
contract invested prior to August 14, 1982, are treated first as a recovery of
the investment in the contract as of that date. A distribution in excess of the
amount of the investment in the contract as of August 14, 1982, will be treated
as taxable income.

The Tax Reform Act of 1986 has changed the tax treatment of certain
Non-Qualified Contracts held by entities other than individuals. Such entities
are taxed currently on earnings from contributions made to the contract after
February 28, 1986. There are exceptions for immediate annuities and certain
contracts owned for the benefit of an individual. An immediate annuity, for
purposes of this discussion, is a single premium contract on which payments
begin within one year of purchase. If this contract is issued as the result of
an exchange described in Section 1035 of the Internal Revenue Code, for purposes
of determining whether the contract is an immediate annuity, it will generally
be considered to have been purchased on the purchase date of the contract given
up in the exchange.

Internal Revenue Code Section 72 also assesses a penalty tax if a distribution
is made before the contract owner reaches age 59 1/2. The amount of the penalty
is 10% of the portion of any distribution that is includible in gross income.
The penalty tax does not apply if the distribution:

     1)  is the result of a contract owner's death;

     2)  is the result of a contract owner's disability;

     3)  is one of a series of substantially equal periodic payments made over
         the life or life expectancy of the contract owner (or the joint lives
         or joint life expectancies of the contract owner and the beneficiary
         selected by the contract owner to receive payment under the annuity
         payment option selected by the contract owner);

     4)  is for the purchase of an immediate annuity; or

     5)  is allocable to an investment in the contract before August 14, 1982.

A contract owner that wants to begin taking distributions to which the 10% tax
penalty does not apply should forward a written request to Nationwide. Upon
receipt of this written request, Nationwide will inform the contract owner of
Nationwide's policies and procedures, as well as contract limitations. An
election to begin taking these withdrawals will be irrevocable and may not be
amended or changed.

In order to qualify as an annuity contract under Section 72 of the Internal
Revenue Code, the contract must provide for distribution of the entire contract
upon a contract owner's death. These rules are described in "Required
Distributions."

The Internal Revenue Code requires that any election to receive an annuity
instead of a lump sum payment be made within 60 days after the lump sum becomes
payable (generally, within 60 days of the death of a contract owner or the
annuitant). As long as the election is made within the 60 day period, each
distribution will be taxable when it is paid. Upon the end of this 60 day
period, if no election has been made, the entire amount of the lump sum will be
subject to immediate tax, even if the payee decides at a later date to take the
distribution as an annuity.

                                       29
<PAGE>   32

Non-Natural Persons as Contract Owners

The previous discussion related to the taxation of Non-Qualified Contracts owned
(or, pursuant to Section 72(u) of the Internal Revenue Code, deemed to be owned)
by individuals. Different rules apply if the contract owner is not a natural
person.

Generally, contracts owned by corporations, partnerships, trusts, and similar
entities ("non-natural persons") are not treated as annuity contracts under the
Internal Revenue Code. Specifically, they are not treated as annuity contracts
for purposes of Section 72. Therefore, income earned under a Non-Qualified
Contract that is owned by a non-natural person is taxed as ordinary income
during the taxable year that it is earned. Taxation is not deferred, even if the
income is not distributed out of the contract to the contract owner.

This non-natural person rule does not apply to all entity-owned contracts. A
contract that is owned by a non-natural person as an agent for an individual is
treated as owned by the individual. This would put the contract back under
Section 72, allowing tax deferral. However, this exception does not apply when
the non-natural person is an employer that holds the contract under a
non-qualified deferred compensation arrangement for one or more employees.

The non-natural person rule also does not apply to contracts that are:

     a)   acquired by the estate of a decedent by reason of the death of the
          decedent;

     b)   issued in connection with certain qualified retirement plans and
          individual retirement plans;

     c)   used in connection with certain structured settlements;

     d)   purchased by an employer upon the termination of certain qualified
          retirement plans; or

     e)   an immediate annuity.

WITHHOLDING

Pre-death distributions from the contracts are subject to federal income tax.
Nationwide will withhold the tax from the distributions unless the contract
owner requests otherwise. Contract owners may not waive withholding if the
distribution is subject to mandatory back-up withholding (if no mandatory
taxpayer identification number is given or if the Internal Revenue Service
notifies Nationwide that mandatory back-up withholding is required), or if it is
an eligible rollover distribution. Mandatory back-up withholding rates are 31%
of income that is distributed.

NON-RESIDENT ALIENS

Generally, a pre-death distribution from a contract to a non-resident alien is
subject to federal income tax at a rate of 30% of the amount of income that is
distributed. Nationwide is required to withhold this amount and send it to the
Internal Revenue Service. Some distributions to non-resident aliens may be
subject to a lower (or no) tax if a treaty applies. In order to obtain the
benefits of such a treaty, the non-resident alien must:

     1)   provide Nationwide with proof of residency and citizenship (in
          accordance with Internal Revenue Service requirements); and

     2)   provide Nationwide with an individual taxpayer identification number.

If the non-resident alien does not meet the above conditions, Nationwide will
withhold 30% of income from the distribution.

Another way to avoid the 30% withholding is for the non-resident alien to
provide Nationwide with sufficient evidence that:

     1)   the distribution is connected to the non-resident alien's conduct of
          business in the United States; and

     2)   the distribution is includible in the non-resident alien's gross
          income for United States federal income tax purposes.

Note that these distributions may be subject to back-up withholding, currently
31%, if a correct taxpayer identification number is not provided.

                                       30
<PAGE>   33

FEDERAL ESTATE, GIFT, AND GENERATION SKIPPING TRANSFER TAXES

The following transfers may be considered a gift for federal gift tax purposes:

     -    a transfer of the contract from one contract owner to another; or

     -    a distribution to someone other than a contract owner.

Upon the contract owner's death, the value of the contract may be subject to
estate taxes, even if all or a portion of the value is also subject to federal
income taxes.

Section 2612 of the Internal Revenue Code may require Nationwide to determine
whether a death benefit or other distribution is a "direct skip" and the amount
of the resulting generation skipping transfer tax, if any. A direct skip is when
property is transferred to, or a death benefit or other distribution is made to:

     a)   an individual who is two or more generations younger than the contract
          owner; or

     b)   certain trusts, as described in Section 2613 of the Internal Revenue
          Code (generally, trusts that have no beneficiaries who are not 2 or
          more generations younger than the contract owner).

If the contract owner is not an individual, then for this purpose, ONLY
"contract owner" refers to any person:

     -    who would be required to include the contract, death benefit,
          distribution, or other payment in his or her federal gross estate at
          his or her death; or

     -    who is required to report the transfer of the contract, death benefit,
          distribution, or other payment for federal gift tax purposes.

If a transfer is a direct skip, Nationwide will deduct the amount of the
transfer tax from the death benefit, distribution or other payment, and remit it
directly to the Internal Revenue Service.

PUERTO RICO

Under the Puerto Rico tax code, distributions from a Non-Qualified Contract
before annuitization are treated as nontaxable return of principal until the
principal is fully recovered. Thereafter all distributions are fully taxable.
Distributions after annuitization are treated as part taxable income and part
nontaxable return of principal. The amount excluded from gross income after
annuitization is equal to the amount of the distribution in excess of 3% of the
total purchase payments paid, until an amount equal to the total purchase
payments paid has been excluded. Thereafter, the entire distribution is included
in gross income. Puerto Rico does not impose an early withdrawal penalty tax.
Generally, Puerto Rico does not require income tax to be withheld from
distributions of income. A personal adviser should be consulted in these
situations.

CHARGE FOR TAX

Nationwide is not required to maintain a capital gain reserve liability on
Non-Qualified Contracts. If tax laws change requiring a reserve, Nationwide may
implement and adjust a tax charge.

DIVERSIFICATION

Internal Revenue Code Section 817(h) contains rules on diversification
requirements for variable annuity contracts. A variable annuity contract that
does not meet these diversification requirements will not be treated as an
annuity, unless:

     -    the failure to diversify was accidental;

     -    the failure is corrected; and

     -    a fine is paid to the Internal Revenue Service.

The amount of the fine will be the amount of tax that would have been paid by
the contract owner if the income, for the period the contract was not
diversified, had been received by the contract owner.

If the violation is not corrected, the contract owner will be considered the
owner of the underlying securities and will be taxed on the earnings of his or
her contract. Nationwide believes that the investments underlying this contract
meet these diversification requirements.

TAX CHANGES

The foregoing tax information is based on Nationwide's understanding of federal
tax laws. It is NOT intended as tax advice. All information is subject to change
without notice. For more details, contact your personal tax and/or financial
adviser.

STATEMENTS AND REPORTS

Nationwide will mail contract owners statements and reports. Therefore, contract
owners should promptly notify Nationwide of any address change.

These mailings will contain:

     -    statements showing the contract's quarterly activity;

     -    confirmation statements showing transactions that affect the
          contract's value. Confirmation statements will not be sent for
          recurring transactions (i.e., Dollar Cost Averaging or salary
          reduction programs). Instead, confirmation of recurring transactions
          will appear in the contract's quarterly statements;

     -    annual and semi-annual reports containing all applicable information
          and financial statements or their equivalent, which must be sent to
          the underlying mutual fund beneficial shareholders as required by the
          rules under the Investment Company Act of 1940 for the variable
          account.

Contract owners should review statements and confirmations carefully. All errors
or corrections must be reported to Nationwide immediately to assure proper
crediting to the contract. Unless Nationwide is notified within 30 days of
receipt of the statement, Nationwide will assume statements and confirmation
statements are correct.

YEAR 2000 COMPLIANCE ISSUES

Nationwide has developed and implemented a plan to address issues related to the
Year 2000. The problem relates to many existing computer systems using only two
digits to identify a year in a date field. These systems were designed and
developed without considering the impact of the upcoming change in the century.
If not corrected, many computer systems could fail or create erroneous results
when processing information dated after December 31, 1999. Like many
organizations, Nationwide is required to renovate or replace many computer
systems so that the systems will function properly after December 31, 1999.


Nationwide has completed an inventory and assessment of all computer systems and
has implemented a plan to renovate or replace all applications that were
identified as not Year 2000 compliant. Nationwide has renovated all applications
that required renovation. Testing of the renovated programs included running
each application in a Year 2000 environment and was completed as planned during
1998. For applications being replaced, Nationwide had all replacement systems in
place and functioning as planned by year-end 1998. The shareholder services
system that supports mutual fund products was fully deployed during the first
quarter 1999. Conversion of existing traditional life policies to the new
compliant system was completed by July 1999.


Nationwide has completed an inventory and assessment of all vendor products and
has tested and certified that each vendor product is Year 2000 compliant. Any
vendor products that could not be certified as Year 2000 compliant were replaced
or eliminated in 1998.


Nationwide's facilities in Columbus, Ohio have been inventoried, assessed and
tested as being Year 2000 compliant. Mission-critical systems supporting
Nationwide's infrastructure such as telecommunications, voice and networks were
renovated and brought into compliance as planned during the second quarter.

Nationwide has also addressed issues associated with the exchange of electronic
data with external organizations. Nationwide has completed an inventory and
assessment of all business partners utilizing electronic interfaces with
Nationwide and processes have been put in place to allow Nationwide to accept
data regardless of the format. During third quarter 1999, contingency plans will
be finalized for



                                       32
<PAGE>   35


other interfaces with our critical business partners.

In addition to resolving internal Year 2000 readiness issues, Nationwide is
conducting a due diligence effort with significant external organizations,
including mutual fund organizations, financial institutions and wholesale
producers, to assess if they will be Year 2000 compliant. This involves
communication and follow-up with critical business partners to determine if they
will be in a position to continue doing business in the Year 2000 and beyond.
The results are currently being gathered and analyzed and these efforts will
continue until compliance is assured or until regulatory rulings indicate
actions to be taken related to non-compliant firms. Contingency plans have been
developed for mutual fund organizations, financial institutions and wholesale
producers who may not become compliant prior to the end of 1999.

As part of its risk management strategy, Nationwide has identified risk
scenarios including the identification of external risk factors that could cause
business interruptions from Year 2000 related events. These risk scenarios
include increased customer service volume, increased producer service volume,
utility failures, technology failures and disruptions in business operations,
finance and cash flow. Nationwide is in the process of developing mitigation and
contingency plans to address these risks that would, except for complete utility
failure, permit uninterrupted service to customers and producers. Contingency
and mitigation plan efforts are expected to be completed during the third
quarter of 1999.


Operating expenses in 1998 and 1997 include approximately $44.7 million and
$45.4 million, respectively, for technology projects, including costs related to
Year 2000. Nationwide anticipates spending approximately $5 million on Year 2000
activities in 1999 and expenditures for the first six months of 1999 totaled
$4.2 million. These expenses do not have an effect on the assets of the variable
account and are not charged through to the contract owner.

Management does not anticipate that the completion of Year 2000 renovation and
replacement activities will result in a reduction in operating expenses. Rather,
personnel and resources currently allocated to Year 2000 issues will be assigned
to other technology-related projects.

LEGAL PROCEEDINGS

Nationwide is a party to litigation and arbitration proceedings in the ordinary
course of its business, none of which is expected to have a material adverse
effect on Nationwide.

In recent years, life insurance companies have been named as defendants in
lawsuits, including class action lawsuits, relating to life insurance and
annuity pricing and sales practices. A number of these lawsuits have resulted in
substantial jury awards or settlements.

In November 1997, two plaintiffs, one who was the owner of a variable life
insurance contract and the other who was the owner of a variable annuity
contract, commenced a lawsuit in a federal court in Texas against Nationwide
Life Insurance Company and the American Century group of defendants (Robert
Young and David D. Distad v. Nationwide Life Insurance Company et al.). In this
lawsuit, plaintiffs sought to represent a class of variable life insurance
contract owners and variable annuity contract owners whom they claim were
allegedly misled when purchasing these variable contracts into believing that
the performance of their underlying mutual fund option managed by American
Century, whose shares may only be purchased by insurance companies, would track
the performance of a mutual fund, also managed by American Century, whose shares
are publicly traded. The amended complaint seeks unspecified compensatory and
punitive damages. On April 27, 1998, the district court denied, in part, and
granted, in part, Nationwide and American Century's motions to dismiss the
complaint. The remaining claims against Nationwide allege securities fraud,
common law fraud, civil conspiracy, and breach of contract. The District Court,
on December 2, 1998, issued an order denying plaintiffs' motion for class



                                       33
<PAGE>   36


certification and the appeals court declined to review the order denying class
certification upon interlocutory appeal. On June 11, 1999, the District Court
denied the plaintiffs' motion to amend their complaint and reconsider class
certification. Nationwide intends to defend this lawsuit (now limited to the
claims of the two named plaintiffs) vigorously.

On October 29, 1998, Nationwide was named in a lawsuit filed in Ohio state court
related to the sale of deferred annuity products for use as investments in
tax-deferred contributory retirement plans (Mercedes Castillo v. Nationwide
Financial Services, Inc., Nationwide Life Insurance Company and Nationwide Life
and Annuity Insurance Company). On May 3, 1999, the complaint was amended to,
among other things, add Marcus Shore as a second plaintiff. The amended
complaint is brought as a class action on behalf of all persons who purchased
individual deferred annuity contracts or participated in group annuity contracts
sold by Nationwide and the other named Nationwide affiliates which were used to
fund certain tax-deferred retirement plans. The amended complaint seeks
unspecified compensatory and punitive damages. On June 11, 1999, Nationwide and
the other named defendants filed a motion to dismiss the amended complaint.
Nationwide intends to defend this lawsuit vigorously.

There can be no assurance that any litigation relating to pricing or sales
practices will not have a material adverse effect on Nationwide in the future.

The general distributor, NAS, is not engaged in any litigation of any material
nature.


ADVERTISING

A "yield" and "effective yield" may be advertised for the NSAT Money Market
Fund. "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 NSAT Money Market Fund's
units. Yield is an annualized figure, which means that it is assumed that the
NSAT Money Market Fund generates the same level of net income over a 52-week
period. The "effective yield" is calculated similarly but includes the effect of
assumed compounding, calculated under rules prescribed by the SEC. The effective
yield will be slightly higher than yield due to this compounding effect.

Nationwide may advertise the performance of a sub-account in relation to the

These rating services and publications rank the underlying mutual funds'
performance against other funds. These rankings may or may not include the
effects of sales charges or other fees.

Financial Rating Services

Nationwide is also ranked and rated by independent financial rating services,
among which are Moody's, Standard & Poor's and A.M. Best Company. Nationwide may
advertise these ratings. These ratings reflect Nationwide's financial strength
or claims-paying ability. The ratings are not intended to reflect the investment
experience or financial strength of the variable account.

Some Nationwide advertisements and endorsements may include lists of
organizations, individuals or other parties that recommend Nationwide or the
contract. Furthermore, Nationwide may occasionally advertise 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 of the Sub-Accounts

Nationwide will advertise historical performance of the sub-accounts. Nationwide
may advertise for the sub-account's standardized average annual total return
("standardized return") calculated in a manner prescribed by the SEC, and
non-standardized total return ("non-standardized return").

Standardized return shows the percentage rate of return of a hypothetical
initial investment of $1,000 for the most recent one, five and ten year periods
(or for a period covering the time the underlying mutual fund has been available
in the variable account if it has not been available for one of the prescribed
periods). This calculation reflects the deduction of CDSC and all charges that
could be assessed to a (1.40%). Standardized return does not reflect the
deduction of state premium taxes, which may be imposed by certain states.

Non-standardized return is calculated similarly to standardized return except
non-standardized return assumes an initial investment of $25,000, with base
contract variable account charges of 1.40% and does NOT reflect CDSC. An assumed
initial investment of $25,000 is used because that amount more accurately
reflects the average contract size.

Both methods of calculation reflect total return for the most recent one, five
and ten year periods (or for a period covering the time the underlying mutual
fund has been in existence). For those underlying mutual funds which have not
been available for one of the prescribed periods, the nonstandardized total
return illustrations will show the investment performance the underlying mutual
funds would have achieved had they been available in the variable account for
one of the periods.

The standardized average annual total return and nonstandardized total return
quotations are calculated using data for the period ended December 31, 1998.
However, Nationwide generally provides performance information more frequently.
Information relating to performance of the sub-accounts is based on historical
earnings and does not represent or guarantee future results.

APPENDIX A: OBJECTIVES FOR UNDERLYING MUTUAL FUNDS

The underlying mutual funds listed below are designed primarily as investments
for variable annuity contracts and variable life insurance policies issued by
insurance companies.

There is no guarantee that the investment objectives will be met.

AMERICAN CENTURY VARIABLE PORTFOLIOS, INC., A MEMBER OF THE AMERICAN CENTURY(SM)
FAMILY OF INVESTMENTS
American Century Variable Portfolios, Inc. was organized as a Maryland
corporation in 1987. It is a diversified, open-end investment management company
that offers its shares only as investment vehicles for variable annuity and
variable life insurance products of insurance companies. American Century
Variable Portfolios, Inc. is managed by American Century Investment Management,
Inc.

     AMERICAN CENTURY VP INCOME & GROWTH
     Investment Objective: Dividend growth, current income and capital
     appreciation. The Fund seeks to achieve its investment objective by
     investing in common stocks. The investment manager constructs the portfolio
     to match the risk characteristics of the S&P 500 Stock Index and then
     optimizes each portfolio to achieve the desired balance of risk and return
     potential. This includes targeting a dividend yield that exceeds that of
     the S&P 500. Such a management technique known as "portfolio optimization"
     may cause the Fund to be more heavily invested in some industries than in
     others. However, the Fund may not invest more than 25% of its total assets
     in companies whose principal business activities are in the same industry.

     AMERICAN CENTURY VP INTERNATIONAL
     Investment Objective: To seek capital growth. The Fund will seek to achieve
     its investment objective by investing primarily in securities of foreign
     companies that meet certain fundamental and technical standards of
     selection and, in the opinion of the investment manager, have potential for
     appreciation. Under normal conditions, the Fund will invest at least 65% of
     its assets in common stocks or other equity securities of issuers from at
     least three countries outside the United States. While securities of United
     States issuers may be included in the portfolio from time to time, it is
     the primary intent of the manager to diversify investments across a broad
     range of foreign issuers. Although the primary investment of the Fund will
     be common stocks (defined to include depository receipts for common stock
     and other equity equivalents), the Fund may also invest in other types of
     securities consistent with the Fund's objective. When the manager believes
     that the total capital growth potential of other securities equals or
     exceeds the potential return of common stocks, the Fund may invest up to
     35% of its assets in such other securities. There can be no assurance that
     the Fund will achieve its objectives.

     AMERICAN CENTURY VP VALUE
     Investment Objective: The investment objective of the Fund is long-term
     capital growth; income is a secondary objective. The equity securities in
     which the Fund will invest will be primarily securities of well-established
     companies with intermediate-to-large market capitalizations that are
     believed by management to be undervalued at the time of purchase. Under
     normal market conditions, the Fund expects to invest at least 80% of the
     value of its total asset in equity securities, including common and
     preferred stock, convertible preferred stock and convertible debt
     obligations.

DREYFUS STOCK INDEX FUND, INC.
The Dreyfus Stock Index Fund, Inc. is an open-end, non-diversified, management
investment company incorporated under Maryland law on January 24, 1989 and

     Investment Objective: To provide investment results that correspond to the
     price and yield performance of publicly traded common stocks in the
     aggregate, as represented by the Standard & Poor's 500 Composite Stock
     Price Index. The Fund is neither sponsored by nor affiliated with Standard
     & Poor's Corporation.

DREYFUS VARIABLE INVESTMENT FUND

Commonwealth of Massachusetts on October 29, 1986 and commenced operations on

     CAPITAL APPRECIATION PORTFOLIO
     Investment Objective: The Portfolio's primary investment objective is to
     provide long-term capital growth consistent with the preservation of
     capital; current income is a secondary investment objective. This Portfolio
     invests primarily in the common stocks of domestic and foreign issuers.


DREYFUS INVESTMENT PORTFOLIOS
Dreyfus Investment Portfolios (the "Fund") is an open-end, management investment
company known as a mutual fund. Shares are offered only to variable annuity and

directly from the Fund. The Dreyfus Corporation serves as the Fund's investment
adviser.

     EUROPEAN EQUITY PORTFOLIO
     Investment Objective: The Portfolio seeks long-term capital growth. To
     pursue this goal, the Portfolio generally invests at least 80% of its total
     assets in stocks included within the universe of the 300 largest European
     companies. The Portfolio may invest up to 10% of its total assets in the
     stocks of non-European companies. The Portfolio's stock investments may
     include common stocks, preferred stocks and convertible securities.


THE DREYFUS SOCIALLY RESPONSIBLE GROWTH FUND, INC.

management investment company incorporated under Maryland law on July 20, 1992

insurance companies. Dreyfus serves as the Fund's investment adviser. NCM
Capital Management Group, Inc. serves as the Fund's sub-investment adviser and
provides day-to-day management of the Fund's portfolio.

     Investment Objective: Capital growth through equity investment in companies
     that, in the opinion of the Fund's advisers, not only meet traditional
     investment standards, but which also show evidence that they conduct their
     business in a manner that contributes to the enhancement of the quality of
     life in America. Current income is secondary to the primary goal.

FEDERATED INSURANCE SERIES
Federated Insurance Series (the "Trust"), an Open-End Management Investment
Company, was established as a Massachusetts business trust, under a Declaration
of Trust dated September 15, 1993. The Trust offers its shares only as
investment vehicles for variable annuity and variable life insurance products of
insurance companies. Federated Advisers serves as the investment adviser.

     FEDERATED QUALITY BOND FUND II
     Investment Objective: Current income by investing in investment grade fixed
     income securities.

FIDELITY VARIABLE INSURANCE PRODUCTS FUND
The Fidelity Variable Insurance Products Fund (VIP) is an open-end, diversified,
management

                                       38
<PAGE>   41

investment company organized as a Massachusetts business trust on
November 13, 1981. Shares of VIP are purchased by insurance companies to fund
benefits under variable life insurance policies and variable annuity contracts.
Fidelity Management & Research Company ("FMR") is the manager for VIP and its
portfolios.

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

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

     VIP HIGH INCOME PORTFOLIO:  SERVICE CLASS
     Investment Objective: High level of current income by investing primarily
     in high-risk, lower-rated, high-yielding, fixed-income securities, while
     also considering growth of capital. FMR will seek high current income
     normally by investing the Portfolio's assets as follows:

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

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

     Higher yields are usually available on securities that are lower-rated or
     that are unrated. Lower-rated securities are usually defined as Ba or lower
     by Moody's Investor Service, Inc. ("Moody's"); BB or lower by Standard &
     Poor's and may be deemed to be of a speculative nature. The Portfolio may
     also purchase lower-quality bonds such as those rated Ca3 by Moody's or C-
     by Standard & Poor's which provide poor protection for payment of principal
     and interest (commonly referred to as "junk bonds"). For a further
     discussion of lower-rated securities, please see the "Risks of Lower-Rated
     Debt Securities" section of the Portfolio's prospectus.

     VIP OVERSEAS PORTFOLIO:  SERVICE CLASS
     Investment Objective: Long-term capital growth primarily through
     investments in foreign securities. This Portfolio provides a means for
     investors to diversify their own portfolios by participating in companies
     and economies outside the United States.

FIDELITY VARIABLE INSURANCE PRODUCTS FUND II
The Fidelity Variable Insurance Products Fund II (VIP II) is an open-end,
diversified, management investment company organized as a Massachusetts business
trust on March 21, 1988. VIP II's shares are purchased by insurance companies to
fund benefits under variable life insurance policies and variable annuity
contracts. FMR is the manager of VIP II and its portfolios.


                                       39
<PAGE>   42


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

FIDELITY VARIABLE INSURANCE PRODUCTS FUND III
The Fidelity Variable Insurance Products Fund III (VIP III) is an open-end,
diversified, management investment company organized as a Massachusetts business
trust on July 14, 1994. VIP III's shares are purchased by insurance companies to
fund benefits under variable life insurance policies and variable annuity
contracts. FMR is the manager of VIP III and it's portfolios.

     VIP III GROWTH OPPORTUNITIES PORTFOLIO:  SERVICE CLASS
     Investment Objective: Capital growth by investing primarily in common
     stocks and securities convertible into common stocks. The Portfolio, under
     normal conditions, will invest at least 65% of its total assets in
     securities of companies that FMR believes have long-term growth potential.
     Although the Portfolio invests primarily in common stock and securities
     convertible into common stock, it has the ability to purchase other
     securities, such as preferred stock and bonds, that may produce capital
     growth. The Portfolio may invest in foreign securities without limitation.

MORGAN STANLEY DEAN WITTER UNIVERSAL FUNDS, INC.
Morgan Stanley Dean Witter Universal Funds, Inc. is a mutual fund designed to
provide investment vehicles for variable annuity contracts and variable life
insurance policies and for certain tax-qualified investors. Its Emerging Markets
Debt Portfolio is managed by Morgan Stanley Dean Witter Investment Management,
Inc.

     EMERGING MARKETS DEBT PORTFOLIO
     Investment Objective: High total return by investing primarily in dollar
     and non-dollar denominated fixed income securities of government and
     government-related issuers located in emerging market countries, which
     securities provide a high level of current income, while at the same time
     holding the potential for capital appreciation if the perceived
     creditworthiness of the issuer improves due to improving economic,
     financial, political, social or other conditions in the country in which
     the issuer is located.


NATIONWIDE SEPARATE ACCOUNT TRUST
Nationwide Separate Account Trust ("NSAT") is a diversified open-end management
investment company created under the laws of Massachusetts. NSAT offers shares
in the mutual funds listed below, each with its own investment objectives.
Shares of NSAT will be sold primarily to separate accounts to fund the benefits
under variable life insurance policies and variable annuity contracts issued by
life insurance companies. Effective September 1, 1999, the investment advisory
services previously performed by Nationwide Advisory Services ("NAS") were
transferred to Villanova Mutual Fund Capital Trust ("VMF"), an affiliate of NAS
and an indirect subsidiary of Nationwide Financial Services, Inc. The portfolio
managers and subadvisers for each of the Funds continue to manage the Funds
after the transfer to VMF.


     CAPITAL APPRECIATION FUND
     Investment Objective:  Long-term capital appreciation.

     GOVERNMENT BOND FUND
     Investment Objective: As high a level of income as is consistent with the
     preservation of capital by investing in a diversified portfolio of
     securities issued or backed by the U.S. Government, its agencies or
     instrumentalities.

     MONEY MARKET FUND
     Investment Objective: As high a level of current income as is consistent
     with the

                                       40
<PAGE>   43

     preservation of capital and maintenance of liquidity.

     TOTAL RETURN FUND
     Investment Objective: To obtain a reasonable, long-term total return on
     invested capital.

     SUBADVISED NATIONWIDE FUNDS

       NATIONWIDE BALANCED FUND
       Subadviser:  Salomon Brothers Asset Management, Inc.
       Investment Objective: Primarily seeks above-average income compared to a
       portfolio entirely invested in equity securities. The Fund's secondary
       objective is to take advantage of opportunities for growth of capital and
       income. The Fund seeks its objective primarily through investments in a
       broad variety of securities, including equity securities, fixed-income
       securities and short-term obligations. Under normal market conditions, it
       is anticipated that the Fund will invest at least 40% of the Fund's total
       assets in equity securities and at least 25% in fixed-income senior
       securities. The Fund's subadviser, Salomon Brothers Asset Management,
       Inc., will have discretion to invest in the full range of maturities of
       fixed-income securities. Generally, most of the Fund's long-term debt
       investments will consist of "investment grade" securities, but the Fund
       may invest up to 20% of its net assets in non-convertible fixed-income
       securities rated below investment grade or determined by the subadviser
       to be of comparable quality. These securities are commonly known as junk
       bonds. In addition, the Fund may invest an unlimited amount in
       convertible securities rated below investment grade.

       NATIONWIDE EQUITY INCOME FUND
       Subadviser:  Federated Investment Counseling
       Investment Objective: Seeks above average income and capital appreciation
       by investing at least 65% of its assets in income-producing equity
       securities. Such equity securities include common stocks, preferred
       stocks, and securities (including debt securities) that are convertible
       into common stocks. The portion of the Fund's total assets invested in
       each type of equity security will vary according to the Fund's
       subadviser's assessment of market, economic conditions and outlook.

       NATIONWIDE GLOBAL EQUITY FUND
       Subadviser:  J. P. Morgan Investment Management Inc.
       Investment Objective: To provide high total return from a globally
       diversified portfolio of equity securities. Total return will consist of
       income plus realized and unrealized capital gains and losses. The Fund
       seeks its investment objective through country allocation, stock
       selection and management of currency exposure. Under normal market
       conditions, J.P. Morgan Investment Management Inc. intends to keep the
       Fund essentially fully invested with at least 65% of the value of its
       total assets in equity securities consisting of common stocks and other
       securities with equity characteristics such as preferred stocks,
       warrants, rights, convertible securities, trust certificates, limited
       partnership interests and equity participations. The Fund's primary
       equity instruments are the common stock of companies based in the
       developed countries around the world. The assets of the Fund will
       ordinarily be invested in the securities of at least five different
       countries.

       NATIONWIDE HIGH INCOME BOND FUND
       Subadviser:  Federated Investment Counseling
       Investment Objective: Seeks to provide high current income by investing
       primarily in a professionally managed, diversified portfolio of fixed
       income securities. To meet its objective, the Fund intends to invest at
       least 65% of its assets in lower-rated fixed income securities such as
       preferred stocks, bonds, debentures, notes, equipment lease certificates
       and equipment trust certificates which are rated BBB or lower by Standard
       & Poor's or Fitch Investors

                                       41
<PAGE>   44

       Service or Baa or lower by Moody's (or if not rated, are determined by
       the Fund's subadviser to be of a comparable quality). Such investments
       are commonly referred to as "junk bonds." For a further discussion of
       lower-rated securities, please see the "High Yield Securities" section
       of the Fund's prospectus.

       NATIONWIDE MULTI SECTOR BOND  FUND
       Subadviser: Salomon Brothers Asset Management, Inc. with Salomon Brothers
       Asset Management Limited
       Investment Objective: Primarily seeks a high level of current income.
       Capital appreciation is a secondary objective. The Fund seeks to achieve
       its objectives by investing in a globally diverse portfolio of
       fixed-income investments and by giving the subadviser, Salomon Brothers
       Asset Management, Inc. broad discretion to deploy the Fund's
       assets among certain segments of the fixed-income market that the
       subadviser believes will best contribute to achievement of the Fund's
       investment objectives. The Fund reserves the right to invest
       predominantly in securities rated in medium or lower categories, or as
       determined by the subadviser to be of comparable quality, commonly
       referred to as "junk bonds." Although the subadviser has the ability to
       invest up to 100% of the Fund's assets in lower-rated securities, the
       subadviser does not anticipate investing in excess of 75% of the Fund's
       assets in such securities. The Subadviser has entered into a subadvisory
       agreement with its London based affiliate, Salomon Brothers Asset
       Management Limited, pursuant to which the subadviser has delegated to
       Salomon Brothers Asset Management Limited responsibility for management
       of the Fund's investments in non-dollar denominated debt securities and
       currency transactions.


       NATIONWIDE MID CAP INDEX FUND (FORMERLY NATIONWIDE SELECT ADVISERS MID
       CAP FUND)
       Subadviser:  The Dreyfus Corporation
       Investment Objective: Capital appreciation. The Fund seeks to match the
       performance of the Standard & Poor's MidCap 400 Index. To pursue this
       goal, the Fund generally is fully invested in all 400 stocks included in
       this index in proportion to their weighting in the index, and in futures
       whose performance is tied to the index. The Fund is neither sponsored by
       nor affiliated with Standard & Poor's Corporation.

       Neuberger Berman, LLC.
       Investment Objective: Seeks capital growth by investing in a broadly
       diversified portfolio of equity securities issued by U.S. and foreign
       companies with market capitalizations in the range of companies
       represented by the Russell 2000, known has small cap companies.  Under
       normal market conditions, the Fund will invest at least 65% of its total
       assets in the equity securities of small cap companies. The balance of
       the Fund's assets may be invested in equity securities of larger cap
       companies.

       NATIONWIDE SMALL CAP VALUE FUND
       Subadviser:  The Dreyfus Corporation
       Investment Objective: The Fund intends to pursue its investment objective
       by investing, under normal market conditions, at least 75% of the Fund's

       NATIONWIDE SMALL COMPANY FUND

       Subadvisers: The Dreyfus Corporation, Neuberger Berman, LLC., Lazard
       Asset Management, Strong Capital Management, Inc. and Credit Suisse
       Asset Management, LLC.

       Investment Objective: Under normal market conditions, the Fund will
       invest at least 65% of its total assets in equity securities of
       companies whose equity market capitalizations at the time of investment
       are similar to the market capitalizations of companies in the Russell
       2000 Small Stock Index.

       NATIONWIDE STRATEGIC GROWTH FUND
       Subadviser:  Strong Capital Management Inc.
       Investment Objective: Capital growth by investing primarily in equity
       securities that the Fund's subadviser believes have above-average growth
       prospects. The Fund will generally invest in companies whose earnings are
       believed to be in a relatively strong growth trend, and to a lesser
       extent, in companies in which significant further growth is not
       anticipated but whose market value is thought to be undervalued. Under
       normal market conditions, the Fund will invest at least 65% of its total
       assets in equity securities, including common stocks, preferred stocks,
       and securities convertible into common or preferred stocks, such as
       warrants and convertible bonds. The Fund may invest up to 35% of its
       total assets in debt obligations, including intermediate- to long-term
       corporate or U.S. Government debt securities.

       NATIONWIDE STRATEGIC VALUE FUND
       Subadviser: Strong Capital Management Inc./Schafer Capital Management
       Inc.
       Investment Objective: Primarily long-term capital appreciation; current
       income is a secondary objective. The Fund seeks to meet its objectives
       by investing in securities which are believed to offer the possibility
       of increase in value, primarily common stocks of established companies
       having a strong financial position and a low stock market valuation
       at the time of purchase in relation to investment value. Other than
       considered appropriate for cash reserves, the Fund will generally
       maintain a fully invested position in common stocks of publicly held
       companies, primarily in stocks of companies listed on a national
       securities exchange or other equity securities (common stock or
       securities convertible into common stock). Investments may also be made
       in debt securities which are convertible into common stocks and in
       warrants or other rights to purchase common stock, which in such case
       are considered equity securities by the Fund. Strong Capital Management,
       Inc. has subcontracted with Schafer Capital Management, Inc. to
       subadvise the Fund.

NEUBERGER BERMAN ADVISERS MANAGEMENT TRUST
Neuberger Berman Advisers Management Trust ("NB AMT") is an open-end,
diversified management investment company consisting of several series. Shares
of the series of NB AMT are offered in connection with certain variable annuity
contracts and variable life insurance policies issued through life insurance
company separate accounts and are also offered directly to qualified pension and
retirement plans outside of the separate account context.

The Guardian, Partners and Mid-Cap Growth Portfolios of NB AMT invest all of
their investable assets in a corresponding series of Advisers Managers Trust
managed by Neuberger Berman Management Incorporated ("NB Management"). Each
series then invests in securities in accordance with an investment objective,
policies and limitations identical to those of the Portfolio. This
"master/feeder fund" structure is different from that of many other investment
companies which directly acquire and manage their own portfolios of securities.
(For more information regarding "master/feeder fund" structure, see "Special
Information Regarding Organization, Capitalization, and Other Matters" in the
underlying mutual fund prospectus.) The investment advisor is NB Management.

<PAGE>   46

     AMT GUARDIAN PORTFOLIO
     Investment Objective: Capital appreciation and secondarily, current income.
     The Portfolio and its corresponding series seek to achieve these objectives
     by investing in common stocks of long-established, high-quality companies.
     NB Management uses a value-oriented investment approach in selecting
     securities, looking for low price-to-earnings ratios, strong balance
     sheets, solid management, and consistent earnings.

     AMT MID-CAP GROWTH PORTFOLIO
     Investment Objective: Capital appreciation by investing in equity
     securities of medium-sized companies that NB Management believes have the
     potential for long-term, above-average capital appreciation. Medium-sized
     companies have market capitalizations form $300 million to $10 billion at
     the time of investment. The Portfolio and its corresponding series may
     invest up to 10% of its net assets, measured at the time of investment, in
     corporate debt securities that are below investment grade or, if unrated,
     deemed by NB Management to be of comparable quality. Securities that are
     below investment grade, as well as unrated securities, are often considered
     to be speculative and usually entail greater risk. As a part of the
     Portfolio's investment strategy, the Portfolio may invest up to 20% of its
     net assets in securities of issuers organized and doing business
     principally outside the United States. This limitation does not apply with
     respect to foreign securities that are denominated in U.S. dollars.

     AMT PARTNERS PORTFOLIO
     Investment Objective: Capital growth by investing primarily in the common
     stock of established companies. Its investment program seeks securities
     believed to be undervalued based on fundamentals such as low
     price-to-earnings ratios, consistent cash flows, and the company's track
     record through all parts of the market cycle.

OPPENHEIMER VARIABLE ACCOUNT FUNDS

     OPPENHEIMER AGGRESSIVE GROWTH FUND/VA (FORMERLY "OPPENHEIMER CAPITAL
     APPRECIATION FUND")
     Investment Objective: Capital appreciation by investing
     in "growth type" companies. Such companies are believed to have relatively
     favorable long-term prospects for increasing demand for their goods or
     services, or to be developing new products, services or markets and
     normally retain a relatively larger portion of their earnings for research,
     development and investment in capital assets. The Fund may also invest in
     cyclical industries in "special situations" that OppenheimerFunds, Inc.
     believes present opportunities for capital growth.

     OPPENHEIMER CAPITAL APPRECIATION FUND/VA (FORMERLY "OPPENHEIMER GROWTH
     FUND)
     Investment Objective: Capital appreciation by investing in securities of
     well-known established companies. Such securities generally have a history
     of earnings and dividends and are issued by seasoned companies (companies
     which have an operating history of at least five years including
     predecessors). Current income is a secondary consideration in the selection
     of the Fund's portfolio securities.

     OPPENHEIMER MAIN STREET GROWTH & INCOME FUND/VA (FORMERLY "OPPENHEIMER
     GROWTH & INCOME FUND")
     Investment Objective: High total return, which
     stocks, preferred stocks, convertible securities and warrants. Debt
     investments will include bonds, participation includes growth in the value
     of its shares as well as current income from quality and debt securities.
     In seeking its investment objectives, the Fund may invest in equity

                                       44
<PAGE>   47

     and debt securities. Equity investments will include common interests,
     asset-backed securities, private-label mortgage-backed securities and CMOs,
     zero coupon securities and U.S. debt obligations, and cash and cash
     equivalents. From time to time, the Fund may focus on small to medium
     capitalization issuers, the securities of which may be subject to greater
     price volatility than those of larger capitalized issuers.

VAN ECK WORLDWIDE INSURANCE TRUST
Van Eck Worldwide Insurance Trust is an open-end management investment company
organized as a business trust under the laws of the Commonwealth of

manager is Van Eck Associates Corporation.

     WORLDWIDE EMERGING MARKETS FUND
     Investment Objective: Seeks long-term capital appreciation by investing
     primarily in equity securities in emerging markets around the world. The
     Fund emphasizes investment in countries that, compared to the world's major
     economies, exhibit relatively low gross national product per capita, as
     well as the potential for rapid economic growth.

     WORLDWIDE HARD ASSETS FUND
     Investment Objective: Long-term capital appreciation by investing primarily
     in "Hard Asset Securities." For the Fund's purpose, "Hard Assets" are real
     estate, energy, timber, and industrial and precious metals. Income is a
     secondary consideration.

VAN KAMPEN LIFE INVESTMENT TRUST

investment company organized as a Delaware business trust. Shares are offered in
separate portfolios which are sold only to insurance companies to provide
funding for variable life insurance policies and variable annuity contracts. Van

     MORGAN STANLEY REAL ESTATE SECURITIES PORTFOLIO
     Investment Objective: Long-term capital growth by investing principally in
     a diversified portfolio of securities of companies operating in the real
     estate industry ("Real Estate Securities"). Current income is a secondary
     consideration. Real Estate Securities include equity securities, including
     common stocks and convertible securities, as well as non-convertible
     preferred stocks and debt securities of real estate industry companies. A
     "real estate industry company" is a company that derives at least 50% of
     its assets (marked to market), gross income or net profits from the
     ownership, construction, management or sale of residential, commercial or
     industrial real estate. Under normal market conditions, at least 65% of the
     Fund's total assets will be invested in Real Estate Securities, primarily
     equity securities of real estate investment trusts. The Portfolio may
     invest up to 25% of its total assets in securities issued by foreign
     issuers, some or all of which may also be Real Estate Securities.


WARBURG PINCUS TRUST

Massachusetts. The Trust offers its shares to insurance companies for allocation
to separate accounts for the purpose of funding variable annuity and variable
life contracts. Portfolios are managed by Credit Suisse Asset Management, LLC
("Credit Suisse").


     GROWTH & INCOME PORTFOLIO

     Investment Objective: Long-term growth of capital and income by investing
     primarily in dividend-paying equity securities. Under normal market
     conditions, the Portfolio will invest substantially all of its asset in
     equity securities that Credit Suisse considers to be relatively undervalued
     based upon research and analysis, taking into account factors such as
     price/book ratio, price/cash flow ratio, earnings growth, debt/capital
     ratio and multiples of earnings of comparable


                                       45
<PAGE>   48

     securities. Although the Portfolio may hold securities of any size, it
     currently expects to focus on companies with market capitalizations of $1
     billion or greater at the time of initial purchase.

GENERAL INFORMATION AND HISTORY

The Nationwide Variable Account -10 is a separate investment account of
Nationwide Life Insurance Company ("Nationwide"). All of Nationwide's common
stock is owned by Nationwide Financial Services, Inc. ("NFS"), a holding
company. NFS has two classes of common stock outstanding with different voting
rights enabling Nationwide Corporation (the holder of all of the outstanding
Class B Common Stock) to control NFS. Nationwide Corporation is a holding
company, as well. All of its common stock is held by Nationwide Mutual Insurance
Company (95.24%) and Nationwide Mutual Fire Insurance Company (4.76%), the
ultimate controlling persons of Nationwide Insurance Enterprise. The Nationwide
Insurance Enterprise is one of America's largest insurance and financial
services family of companies, with combined assets of over $98.28 billion as of
December 31, 1998.

SERVICES

Nationwide, which has responsibility for administration of the contracts and the
variable account, maintains records of the name, address, taxpayer
identification number, and other pertinent information for each contract owner
and the number and type of contract issued to each contract owner and records
with respect to the contract value.

The custodian of the assets of the variable account is Nationwide. Nationwide
will maintain a record of all purchases and redemptions of shares of the
underlying mutual funds. Nationwide, or affiliates of Nationwide, may have
entered into agreements with either the investment adviser or distributor for
the underlying mutual funds. The agreements relate to administrative services
furnished by Nationwide or an affiliate of Nationwide and provide for an annual
fee based on the average aggregate net assets of the variable account (and other
separate accounts of Nationwide or life insurance company subsidiaries of
Nationwide) invested in particular underlying mutual funds. These fees in no way
affect the net asset value of the underlying mutual funds or fees paid by the
contract owner.

The audited financial statements have been included herein in reliance upon the
reports of KPMG LLP, independent certified public accountants, Two Nationwide
Plaza, Columbus, Ohio 43215, and upon the authority of said firm as experts in
accounting and auditing.

PURCHASE OF SECURITIES BEING OFFERED

The contracts will be sold by licensed insurance agents in the states where the
contracts may be lawfully sold. Such agents will be registered representatives
of broker-dealers registered under the Securities Exchange Act of 1934 who are
members of the National Association of Securities Dealers, Inc. ("NASD").

UNDERWRITERS

The contracts, which are offered continuously, are distributed by Nationwide
Advisory Services, Inc. ("NAS"), One Nationwide Plaza, Columbus, Ohio 43215, a
wholly owned subsidiary of Nationwide. During the fiscal years ended December
31, 1998, 1997 and 1996, no underwriting commissions were paid by Nationwide to
NAS.

CALCULATIONS OF PERFORMANCE

Any current yield quotations of the NSAT Money Market Fund, subject to Rule 482
of the Securities Act of 1933, will consist of a seven calendar day historical
yield, carried at least to the nearest hundredth of a percent. The yield will be
calculated by determining the net change, exclusive of capital changes, in the
value of a hypothetical pre-existing account having a balance of one
accumulation unit at the beginning of the base period, subtracting a
hypothetical charge reflecting deductions from contract owner accounts, and
dividing the net change in account value by the value of the account at the
beginning of the period to obtain a base period return, and multiplying the base
period return by (365/7) or (366/7) in a leap year. At December 31, 1998, the
NSAT Money Market Fund's seven-day current unit value yield was 3.77%. The NSAT
Money Market Fund's effective yield is computed similarly, but includes the
effect of assumed compounding on an annualized basis of the current unit value
yield quotations of the NSAT Money Market Fund. At December 31, 1998 the NSAT
Money Market Fund's seven-day effective yield was 3.84%.

The NSAT Money Market Fund's yield and effective yield will fluctuate daily.
Actual yields will depend on factors such as the type of instruments in the
fund's portfolio, portfolio quality and average maturity, changes in interest
rates, and the fund's expenses. Although the NSAT Money Market Fund determines
its yield on the basis of a seven day period, it may use a different time period
on occasion. The yield quotes may reflect the expense limitation described
"Investment Manager and Other Services" in the NSAT Money Market Fund's
Statement of Additional Information. There is no assurance that the yields
quoted on any given occasion will remain in effect for any period of time and
there is no guarantee that the net asset values will remain constant. It should
be noted that a contract owner's investment in the NSAT Money Market Fund is not
guaranteed or insured. Yields of other money market funds may not be comparable
if a different base period or another method of calculation is used.

All performance advertising will include quotations of standardized average
annual total return, calculated in accordance with a standard method prescribed
by rules of the SEC. Standardized average annual total return is found by taking
a hypothetical $1,000 investment in each of the sub-accounts' units on the first
day of the period at the offering price, which is the accumulation unit value
per unit ("initial investment") and computing the ending redeemable value
("redeemable value") of that investment at the end of the period. The redeemable
value is then divided by the initial investment and this quotient is taken to
the Nth root (N represents the number of years in the period) and 1 is
subtracted from the result which is then expressed as a percentage, carried to
at least the nearest hundredth of a percent. Standardized average annual total
return reflects the deduction of CDSC and all charges that could be assessed to
a contract (1.40%), except for premium taxes, which may be imposed by certain
states. Nonstandardized total return may also be advertised, and is calculated
in a manner similar to standardized

                                       2
<PAGE>   51

average annual total return except the nonstandardized total return is based on
a hypothetical initial investment of $25,000, with contract variable account
charges of 1.40% and does NOT reflect CDSC. An assumed initial investment of
$25,000 will be used because that figure more closely approximates the size of a
typical contract than does the $1,000 figure used in calculating the
standardized average annual total return quotations.

The standardized average annual total return and nonstandardized average annual
total return quotations will be current to the last day of the calendar quarter
preceding the date on which an advertisement is submitted for publication. The
standardized average annual return will be based on rolling calendar quarters
and will cover periods of one, five, and ten years, or a period covering the
time the underlying mutual fund has been available in the variable account if
the underlying mutual fund has not been available for one of the prescribed
periods. Nonstandardized average annual total return will based on rolling
calendar quarters and will cover periods of one, five and ten years, or a period
covering the time the underlying mutual fund has been in existence.

Quotations of average annual total return and total return are based upon
historical earnings and will fluctuate. Any quotation of performance, is not a
guarantee of future performance. Factors affecting a sub-account's performance
include general market conditions, operating expenses and investment management.
A contract owner's account when redeemed may be more or less than the original
cost.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors
Nationwide Life Insurance Company:

We have audited the accompanying consolidated balance sheets of Nationwide Life
Insurance Company and subsidiaries (collectively the Company), a wholly owned
subsidiary of Nationwide Financial Services, Inc., as of December 31, 1998 and
1997, and the related consolidated statements of income, shareholder's equity
and cash flows for each of the years in the three-year period ended December 31,
1998. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Nationwide Life
Insurance Company and subsidiaries as of December 31, 1998 and 1997, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1998, in conformity with generally accepted
accounting principles.

               NATIONWIDE LIFE INSURANCE COMPANY AND SUBSIDIARIES
       (a wholly owned subsidiary of Nationwide Financial Services, Inc.)

                   Notes to Consolidated Financial Statements

                        December 31, 1998, 1997 and 1996



(1)      Organization and Description of Business
         ----------------------------------------

         Prior to January 27, 1997, Nationwide Life Insurance Company (NLIC) was
         wholly owned by Nationwide Corporation (Nationwide Corp.). On that
         date, Nationwide Corp. contributed the outstanding shares of NLIC's
         common stock to Nationwide Financial Services, Inc. (NFS), a holding
         company formed by Nationwide Corp. in November 1996 for NLIC and the
         other companies within the Nationwide Insurance Enterprise that offer
         or distribute long-term savings and retirement products. On March 11,
         1997, NFS completed an initial public offering of its Class A common
         stock.

         During 1996 and 1997, Nationwide Corp. and NFS completed certain
         transactions in anticipation of the initial public offering that
         focused the business of NFS on long-term savings and retirement
         products. On September 24, 1996, NLIC declared a dividend payable to
         Nationwide Corp. on January 1, 1997 consisting of the outstanding
         shares of common stock of certain subsidiaries that do not offer or
         distribute long-term savings or retirement products. In addition,
         during 1996, NLIC entered into two reinsurance agreements whereby all
         of NLIC's accident and health and group life insurance business was
         ceded to two affiliates effective January 1, 1996. These subsidiaries,
         through December 31, 1996, and all accident and health and group life
         insurance business have been accounted for as discontinued operations
         for all periods presented. See notes 10 and 14. Additionally, NLIC paid
         $900.0 million of dividends, $50.0 million to Nationwide Corp. on
         December 31, 1996 and $850.0 million to NFS, which then made an
         equivalent dividend to Nationwide Corp., on February 24, 1997.

         NFS contributed $836.8 million to the capital of NLIC during March
         1997.

         Wholly owned subsidiaries of NLIC include Nationwide Life and Annuity
         Insurance Company (NLAIC), Nationwide Advisory Services, Inc.,
         Nationwide Investment Services Corporation and NWE, Inc. NLIC and its
         subsidiaries are collectively referred to as "the Company."

         The Company is a leading provider of long-term savings and retirement
         products, including variable annuities, fixed annuities and life
         insurance.

(2)      Summary of Significant Accounting Policies
         ------------------------------------------

         The significant accounting policies followed by the Company that
         materially affect financial reporting are summarized below. The
         accompanying consolidated financial statements have been prepared in
         accordance with generally accepted accounting principles, which differ
         from statutory accounting practices prescribed or permitted by
         regulatory authorities. Annual Statements for NLIC and NLAIC, filed
         with the Department of Insurance of the State of Ohio (the Department),
         are prepared on the basis of accounting practices prescribed or
         permitted by the Department. Prescribed statutory accounting practices
         include a variety of publications of the National Association of
         Insurance Commissioners (NAIC), as well as state laws, regulations and
         general administrative rules. Permitted statutory accounting practices
         encompass all accounting practices not so prescribed. The Company has
         no material permitted statutory accounting practices.

       (a wholly owned subsidiary of Nationwide Financial Services, Inc.)

              Notes to Consolidated Financial Statements, Continued



         In preparing the consolidated financial statements, management is
         required to make estimates and assumptions that affect the reported
         amounts of assets and liabilities and the disclosures of contingent
         assets and liabilities as of the date of the consolidated financial
         statements and the reported amounts of revenues and expenses for the
         reporting period. Actual results could differ significantly from those
         estimates.

         The most significant estimates include those used in determining
         deferred policy acquisition costs, valuation allowances for mortgage
         loans on real estate and real estate investments and the liability for
         future policy benefits and claims. Although some variability is
         inherent in these estimates, management believes the amounts provided
         are adequate.

         (a)  Consolidation Policy
              --------------------

              The consolidated financial statements include the accounts of NLIC
              and its wholly owned subsidiaries. Operations that are classified
              and reported as discontinued operations are not consolidated but
              rather are reported as "Income from discontinued operations" in
              the accompanying consolidated statements of income. All
              significant intercompany balances and transactions have been
              eliminated.

         (b)  Valuation of Investments and Related Gains and Losses
              -----------------------------------------------------

              The Company is required to classify its fixed maturity securities
              and equity securities as either held-to-maturity,
              available-for-sale or trading. Fixed maturity securities are
              classified as held-to-maturity when the Company has the positive
              intent and ability to hold the securities to maturity and are
              stated at amortized cost. Fixed maturity securities not classified
              as held-to-maturity and all equity securities are classified as
              available-for-sale and are stated at fair value, with the
              unrealized gains and losses, net of adjustments to deferred policy
              acquisition costs and deferred federal income tax, reported as a
              separate component of shareholder's equity. The adjustment to
              deferred policy acquisition costs represents the change in
              amortization of deferred policy acquisition costs that would have
              been required as a charge or credit to operations had such
              unrealized amounts been realized. The Company has no fixed
              maturity securities classified as held-to-maturity or trading as
              of December 31, 1998 or 1997.

              Mortgage loans on real estate are carried at the unpaid principal
              balance less valuation allowances. The Company provides valuation
              allowances for impairments of mortgage loans on real estate based
              on a review by portfolio managers. The measurement of impaired
              loans is based on the present value of expected future cash flows
              discounted at the loan's effective interest rate or, as a
              practical expedient, at the fair value of the collateral, if the
              loan is collateral dependent. Loans in foreclosure and loans
              considered to be impaired are placed on non-accrual status.
              Interest received on non-accrual status mortgage loans on real
              estate is included in interest income in the period received.

              Real estate is carried at cost less accumulated depreciation and
              valuation allowances. Other long-term investments are carried on
              the equity basis, adjusted for valuation allowances. Impairment
              losses are recorded on long-lived assets used in operations when
              indicators of impairment are present and the undiscounted cash
              flows estimated to be generated by those assets are less than the
              assets' carrying amount.

              Realized gains and losses on the sale of investments are
              determined on the basis of specific security identification.
              Estimates for valuation allowances and other than temporary
              declines are included in realized gains and losses on investments.

         (c)  Revenues and Benefits
              ---------------------

              Investment Products and Universal Life Insurance Products:
              Investment products consist primarily of individual and group
              variable and fixed deferred annuities. Universal life insurance
              products include universal life insurance, variable universal life
              insurance, corporate owned life insurance and other
              interest-sensitive life insurance policies. Revenues for
              investment products and universal life insurance products consist
              of net investment income, asset fees, cost of insurance, policy
              administration and surrender charges that have been earned and
              assessed against policy account balances during the period. Policy
              benefits and claims that are charged to expense include interest
              credited to policy account balances and benefits and claims
              incurred in the period in excess of related policy account
              balances.

              Traditional Life Insurance Products: Traditional life insurance
              products include those products with fixed and guaranteed premiums
              and benefits and consist primarily of whole life insurance,
              limited-payment life insurance, term life insurance and certain
              annuities with life contingencies. Premiums for traditional life
              insurance products are recognized as revenue when due. Benefits
              and expenses are associated with earned premiums so as to result
              in recognition of profits over the life of the contract. This
              association is accomplished by the provision for future policy
              benefits and the deferral and amortization of policy acquisition
              costs.

         (d)  Deferred Policy Acquisition Costs
              ---------------------------------

              The costs of acquiring new business, principally commissions,
              certain expenses of the policy issue and underwriting department
              and certain variable sales expenses have been deferred. For
              investment products and universal life insurance products,
              deferred policy acquisition costs are being amortized with
              interest over the lives of the policies in relation to the present
              value of estimated future gross profits from projected interest
              margins, asset fees, cost of insurance, policy administration and
              surrender charges. For years in which gross profits are negative,
              deferred policy acquisition costs are amortized based on the
              present value of gross revenues. For traditional life insurance
              products, these deferred policy acquisition costs are
              predominantly being amortized with interest over the premium
              paying period of the related policies in proportion to the ratio
              of actual annual premium revenue to the anticipated total premium
              revenue. Such anticipated premium revenue was estimated using the
              same assumptions as were used for computing liabilities for future
              policy benefits. Deferred policy acquisition costs are adjusted to
              reflect the impact of unrealized gains and losses on fixed
              maturity securities available-for-sale as described in note 2(b).

         (e)  Separate Accounts
              -----------------

              Separate account assets and liabilities represent contractholders'
              funds which have been segregated into accounts with specific
              investment objectives. For all but $743.9 million of separate
              account assets, the investment income and gains or losses of these
              accounts accrue directly to the contractholders. The activity of
              the separate accounts is not reflected in the consolidated
              statements of income and cash flows except for the fees the
              Company receives.

         (f)  Future Policy Benefits
              ----------------------

              Future policy benefits for investment products in the accumulation
              phase, universal life insurance and variable universal life
              insurance policies have been calculated based on participants'
              contributions plus interest credited less applicable contract
              charges. The average interest rate credited on investment product
              policy reserves was 6.0%, 6.1% and 6.3% for the years ended
              December 31, 1998, 1997 and 1996, respectively.

              Future policy benefits for traditional life insurance policies
              have been calculated by the net level premium method using
              interest rates varying from 6.0% to 10.5% and estimates of
              mortality, morbidity, investment yields and withdrawals which were
              used or which were being experienced at the time the policies were
              issued, rather than the assumptions prescribed by state regulatory
              authorities.

         (g)  Participating Business
              ----------------------

              Participating business represents approximately 40% in 1998 (50%
              in 1997 and 52% in 1996) of the Company's life insurance in force,
              74% in 1998 (77% in 1997 and 78% in 1996) of the number of life
              insurance policies in force, and 14% in 1998 (27% in 1997 and 40%
              in 1996) of life insurance statutory premiums. The provision for
              policyholder dividends is based on current dividend scales and is
              included in "Future policy benefits and claims" in the
              accompanying consolidated balance sheets.

         (h)  Federal Income Tax
              ------------------

              The Company files a consolidated federal income tax return with
              Nationwide Mutual Insurance Company (NMIC), the majority
              shareholder of Nationwide Corp. The members of the consolidated
              tax return group have a tax sharing arrangement which provides, in
              effect, for each member to bear essentially the same federal
              income tax liability as if separate tax returns were filed.

              The Company utilizes the asset and liability method of accounting
              for income tax. Under this method, deferred tax assets and
              liabilities are recognized for the future tax consequences
              attributable to differences between the financial statement
              carrying amounts of existing assets and liabilities and their
              respective tax bases and operating loss and tax credit
              carryforwards. Deferred tax assets and liabilities are measured
              using enacted tax rates expected to apply to taxable income in the
              years in which those temporary differences are expected to be
              recovered or settled. Under this method, the effect on deferred
              tax assets and liabilities of a change in tax rates is recognized
              in income in the period that includes the enactment date.
              Valuation allowances are established when necessary to reduce the
              deferred tax assets to the amounts expected to be realized.

         (i)  Reinsurance Ceded
              -----------------

              Reinsurance premiums ceded and reinsurance recoveries on benefits
              and claims incurred are deducted from the respective income and
              expense accounts. Assets and liabilities related to reinsurance
              ceded are reported on a gross basis. All of the Company's accident
              and health and group life insurance business is ceded to
              affiliates and is accounted for as discontinued operations. See
              notes 10 and 14.

(j)           Recently Issued Accounting Pronouncements
              -----------------------------------------

              On January 1, 1998 the Company adopted SFAS No. 131 - Disclosures
              about Segments of an Enterprise and Related Information (SFAS
              131). SFAS 131 supersedes SFAS No. 14 - Financial Reporting for
              Segments of a Business Enterprise. SFAS 131 establishes standards
              for public business enterprises to report information about
              operating segments in annual financial statements and selected
              information about operating segments in interim financial reports.
              SFAS 131 also establishes standards for related disclosures about
              products and services, geographic areas, and major customers. The
              adoption of SFAS 131 did not affect results of operations or
              financial position, nor did it affect the manner in which the
              Company defines its operating segments. The segment information
              required for annual financial statements is included in note 13.

              On January 1, 1998, the Company adopted SFAS No. 132 - Employers'
              Disclosures about Pensions and Other Postretirement Benefits (SFAS
              132). SFAS 132 revises employers' disclosures about pension and
              other postretirement benefit plans. The Statement does not change
              the measurement or recognition of benefit plans in the financial
              statements. The revised disclosures required by SFAS 132 are
              included in note 8.

              In June 1998, the FASB issued SFAS No. 133 - Accounting for
              Derivative Instruments and Hedging Activities (SFAS 133). SFAS 133
              establishes accounting and reporting standards for derivative
              instruments and for hedging activities. Contracts that contain
              embedded derivatives, such as certain insurance contracts, are
              also addressed by the Statement. SFAS 133 requires that an entity
              recognize all derivatives as either assets or liabilities in the
              statement of financial position and measure those instruments at
              fair value. The Statement is effective for fiscal years beginning
              after June 15, 1999. It may be implemented earlier provided
              adoption occurs as of the beginning of any fiscal quarter after
              issuance. The Company plans to adopt this Statement in first
              quarter 2000 and is currently evaluating the impact on results of
              operations and financial condition.

              In March 1998, The American Institute of Certified Public
              Accountant's Accounting Standards Executive Committee issued
              Statement of Position 98-1 - Accounting for the Costs of Computer
              Software Developed or Obtained for Internal Use (SOP 98-1). SOP
              98-1 provides guidance intended to standardize accounting
              practices for costs incurred to develop or obtain computer
              software for internal use. Specifically, SOP 98-1 provides
              guidance for determining whether computer software is for internal
              use and when costs incurred for internal use software are to be
              capitalized. SOP 98-1 is effective for financial statements for
              fiscal years beginning after December 15, 1998. The Company does
              not expect the adoption of SOP 98-1, which occurred on January 1,
              1999, to have a material impact on the Company's financial
              statements.


         (k)  Reclassification
              ----------------

              Certain items in the 1997 and 1996 consolidated financial
              statements have been reclassified to conform to the 1998
              presentation.

         Proceeds from the sale of securities available-for-sale during 1998,
         1997 and 1996 were $610.5 million, $574.5 million and $299.6 million,
         respectively. During 1998, gross gains of $9.0 million ($9.9 million
         and $6.6 million in 1997 and 1996, respectively) and gross losses of
         $7.6 million ($18.0 million and $6.9 million in 1997 and 1996,
         respectively) were realized on those sales. In addition, gross gains of
         $15.1 million and gross losses of $0.7 million were realized in 1997
         when the Company paid a dividend to NFS, which then made an equivalent
         dividend to Nationwide Corp., consisting of securities having an
         aggregate fair value of $850.0 million.

         The recorded investment of mortgage loans on real estate considered to
         be impaired as of December 31, 1998 was $3.7 million. No valuation
         allowance has been recorded for these loans as of December 31, 1998.
         The recorded investment of mortgage loans on real estate considered to
         be impaired as of December 31, 1997 was $19.9 million which includes
         $3.9 million of impaired mortgage loans on real estate for which the
         related valuation allowance was $0.1 million and $16.0 million of
         impaired mortgage loans on real estate for which there was no valuation
         allowance. During 1998, the average recorded investment in impaired
         mortgage loans on real estate was approximately $9.1 million ($31.8
         million in 1997) and interest income recognized on those loans was $0.3
         million ($1.0 million in 1997), which is equal to interest income
         recognized using a cash-basis method of income recognition.

         In assessing the realizability of deferred tax assets, management
         considers whether it is more likely than not that some portion of the
         total gross deferred tax assets will not be realized. Nearly all future
         deductible amounts can be offset by future taxable amounts or recovery
         of federal income tax paid within the statutory carryback period. There
         has been no change in the valuation allowance for the years ended
         December 31, 1998, 1997 and 1996.

         Federal income tax expense attributable to income from continuing
         operations for the years ended December 31 was as follows:

(5)      Comprehensive Income
         --------------------

         Pursuant to SFAS No. 130 - Reporting Comprehensive Income, which the
         Company adopted January 1, 1998, the Consolidated Statements of
         Shareholder's Equity include a new measure called "Comprehensive
         Income". Comprehensive Income includes net income as well as certain
         items that are reported directly within separate components of
         shareholders' equity that bypass net income. Currently, the Company's
         only component of Other Comprehensive Income is unrealized gains
         (losses) on securities available-for-sale. The related before and after
         federal tax amounts are as follows:

(6)      Fair Value of Financial Instruments
         -----------------------------------

         The following disclosures summarize the carrying amount and estimated
         fair value of the Company's financial instruments. Certain assets and
         liabilities are specifically excluded from the disclosure requirements
         of financial instruments. Accordingly, the aggregate fair value amounts
         presented do not represent the underlying value of the Company.




<PAGE>   16

               NATIONWIDE LIFE INSURANCE COMPANY AND SUBSIDIARIES
       (a wholly owned subsidiary of Nationwide Financial Services, Inc.)

              Notes to Consolidated Financial Statements, Continued



         The fair value of a financial instrument is defined as the amount at
         which the financial instrument could be exchanged in a current
         transaction between willing parties. In cases where quoted market
         prices are not available, fair value is to be based on estimates using
         present value or other valuation techniques. Many of the Company's
         assets and liabilities subject to the disclosure requirements are not
         actively traded, requiring fair values to be estimated by management
         using present value or other valuation techniques. These techniques are
         significantly affected by the assumptions used, including the discount
         rate and estimates of future cash flows. Although fair value estimates
         are calculated using assumptions that management believes are
         appropriate, changes in assumptions could cause these estimates to vary
         materially. In that regard, the derived fair value estimates cannot be
         substantiated by comparison to independent markets and, in many cases,
         could not be realized in the immediate settlement of the instruments.

         Although insurance contracts, other than policies such as annuities
         that are classified as investment contracts, are specifically exempted
         from the disclosure requirements, estimated fair value of policy
         reserves on life insurance contracts is provided to make the fair value
         disclosures more meaningful.

         The tax ramifications of the related unrealized gains and losses can
         have a significant effect on fair value estimates and have not been
         considered in the estimates.

         The following methods and assumptions were used by the Company in
         estimating its fair value disclosures:

              Fixed maturity and equity securities: The fair value for fixed
              maturity securities is based on quoted market prices, where
              available. For fixed maturity securities not actively traded, fair
              value is estimated using values obtained from independent pricing
              services or, in the case of private placements, is estimated by
              discounting expected future cash flows using a current market rate
              applicable to the yield, credit quality and maturity of the
              investments. The fair value for equity securities is based on
              quoted market prices. The carrying amount and fair value for
              equity securities exclude the fair value of futures contracts
              designated as hedges of equity securities.

              Mortgage loans on real estate, net: The fair value for mortgage
              loans on real estate is estimated using discounted cash flow
              analyses, using interest rates currently being offered for similar
              loans to borrowers with similar credit ratings. Loans with similar
              characteristics are aggregated for purposes of the calculations.
              Fair value for mortgage loans in default is the estimated fair
              value of the underlying collateral.

              Policy loans, short-term investments and cash: The carrying amount
              reported in the consolidated balance sheets for these instruments
              approximates their fair value.

              Separate account assets and liabilities: The fair value of assets
              held in separate accounts is based on quoted market prices. The
              fair value of liabilities related to separate accounts is the
              amount payable on demand, which is net of certain surrender
              charges.

              Investment contracts: The fair value for the Company's liabilities
              under investment type contracts is disclosed using two methods.
              For investment contracts without defined maturities, fair value is
              the amount payable on demand. For investment contracts with known
              or determined maturities, fair value is estimated using discounted
              cash flow analysis. Interest rates used are similar to currently
              offered contracts with maturities consistent with those remaining
              for the contracts being valued.

              Policy reserves on life insurance contracts: Included are
              disclosures for individual life insurance, universal life
              insurance and supplementary contracts with life contingencies for
              which the estimated fair value is the amount payable on demand.
              Also included are disclosures for the Company's limited payment
              policies, which the Company has used discounted cash flow analyses
              similar to those used for investment contracts with known
              maturities to estimate fair value.

              Commitments to extend credit: Commitments to extend credit have
              nominal fair value because of the short-term nature of such
              commitments. See note 7.

              Futures contracts: The fair value for futures contracts is based
              on quoted market prices.

           Carrying amount and estimated fair value of financial instruments
           subject to disclosure requirements and policy reserves on life
           insurance contracts were as follows as of December 31:

(7)      Risk Disclosures
         ----------------

         The following is a description of the most significant risks facing
         life insurers and how the Company mitigates those risks:

         Credit Risk: The risk that issuers of securities owned by the Company
         or mortgagors on mortgage loans on real estate owned by the Company
         will default or that other parties, including reinsurers, which owe the
         Company money, will not pay. The Company minimizes this risk by
         adhering to a conservative investment strategy, by maintaining
         reinsurance and credit and collection policies and by providing for any
         amounts deemed uncollectible.

         Interest Rate Risk: The risk that interest rates will change and cause
         a decrease in the value of an insurer's investments. This change in
         rates may cause certain interest-sensitive products to become
         uncompetitive or may cause disintermediation. The Company mitigates
         this risk by charging fees for non-conformance with certain policy
         provisions, by offering products that transfer this risk to the
         purchaser, and/or by attempting to match the maturity schedule of its
         assets with the expected payouts of its liabilities. To the extent that
         liabilities come due more quickly than assets mature, an insurer would
         have to borrow funds or sell assets prior to maturity and potentially
         recognize a gain or loss.

              Notes to Consolidated Financial Statements, Continued



         Legal/Regulatory Risk: The risk that changes in the legal or regulatory
         environment in which an insurer operates will result in increased
         competition, reduced demand for a company's products, or create
         additional expenses not anticipated by the insurer in pricing its
         products. The Company mitigates this risk by offering a wide range of
         products and by operating throughout the United States, thus reducing
         its exposure to any single product or jurisdiction, and also by
         employing underwriting practices which identify and minimize the
         adverse impact of this risk.

         Financial Instruments with Off-Balance-Sheet Risk: The Company is a
         party to financial instruments with off-balance-sheet risk in the
         normal course of business through management of its investment
         portfolio. These financial instruments include commitments to extend
         credit in the form of loans. These instruments involve, to varying
         degrees, elements of credit risk in excess of amounts recognized on the
         consolidated balance sheets.

         Commitments to fund fixed rate mortgage loans on real estate are
         agreements to lend to a borrower, and are subject to conditions
         established in the contract. Commitments generally have fixed
         expiration dates or other termination clauses and may require payment
         of a deposit. Commitments extended by the Company are based on
         management's case-by-case credit evaluation of the borrower and the
         borrower's loan collateral. The underlying mortgage property represents
         the collateral if the commitment is funded. The Company's policy for
         new mortgage loans on real estate is to lend no more than 75% of
         collateral value. Should the commitment be funded, the Company's
         exposure to credit loss in the event of nonperformance by the borrower
         is represented by the contractual amounts of these commitments less the
         net realizable value of the collateral. The contractual amounts also
         represent the cash requirements for all unfunded commitments.
         Commitments on mortgage loans on real estate of $156.0 million
         extending into 1999 were outstanding as of December 31, 1998. The
         Company also had $40.0 million of commitments to purchase fixed
         maturity securities outstanding as of December 31, 1998.

         Significant Concentrations of Credit Risk: The Company grants mainly
         commercial mortgage loans on real estate to customers throughout the
         United States. The Company has a diversified portfolio with no more
         than 22% (20% in 1997) in any geographic area and no more than 2% (2%
         in 1997) with any one borrower as of December 31, 1998. As of December
         31, 1998, 42% (46% in 1997) of the remaining principal balance of the
         Company's commercial mortgage loan portfolio financed retail
         properties.

         Reinsurance: The Company has entered into a reinsurance contract to
         cede a portion of its general account individual annuity business to
         The Franklin Life Insurance Company (Franklin). Total recoveries due
         from Franklin were $187.9 million and $220.2 million as of December 31,
         1998 and 1997, respectively. The contract is immaterial to the
         Company's results of operations. The ceding of risk does not discharge
         the original insurer from its primary obligation to the policyholder.
         Under the terms of the contract, Franklin has established a trust as
         collateral for the recoveries. The trust assets are invested in
         investment grade securities, the market value of which must at all
         times be greater than or equal to 102% of the reinsured reserves.

(8)      Pension Plan and Postretirement Benefits Other Than Pensions
         ------------------------------------------------------------

         The Company is a participant, together with other affiliated companies,
         in a pension plan covering all employees who have completed at least
         one year of service. The Company funds pension costs accrued for direct
         employees plus an allocation of pension costs accrued for employees of
         affiliates whose work efforts benefit the Company. Assets of the
         Retirement Plan are invested in group annuity contracts of NLIC and
         Employers Life Insurance Company of Wausau (ELICW).

         Pension costs charged to operations by the Company during the years
         ended December 31, 1998, 1997 and 1996 were $2.0 million, $7.5 million
         and $7.4 million, respectively. The Company has recorded a prepaid
         pension asset of $5.0 million as of December 31, 1998 and no prepaid or
         accrued pension asset or expense as of December 31, 1997.

         In addition to the defined benefit pension plan, the Company, together
         with other affiliated companies, participates in life and health care
         defined benefit plans for qualifying retirees. Postretirement life and
         health care benefits are contributory and generally available to full
         time employees who have attained age 55 and have accumulated 15 years
         of service with the Company after reaching age 40. Postretirement
         health care benefit contributions are adjusted annually and contain
         cost-sharing features such as deductibles and coinsurance. In addition,
         there are caps on the Company's portion of the per-participant cost of
         the postretirement health care benefits. These caps can increase
         annually, but not more than three percent. The Company's policy is to
         fund the cost of health care benefits in amounts determined at the
         discretion of management. Plan assets are invested primarily in group
         annuity contracts of NLIC.

         The Company elected to immediately recognize its estimated accumulated
         postretirement benefit obligation (APBO), however, certain affiliated
         companies elected to amortize their initial transition obligation over
         periods ranging from 10 to 20 years.

         The Company's accrued postretirement benefit expense as of December 31,
         1998 and 1997 was $40.1 million and $36.5 million, respectively, and
         the net periodic postretirement benefit cost (NPPBC) for 1998, 1997 and
         1996 was $4.1 million, $3.0 million and $3.3 million, respectively.

         Information regarding the funded status of the pension plan as a whole
         and the postretirement life and health care benefit plan as a whole as
         of December 31, 1998 and 1997 follows:

         Effective December 31, 1998, Wausau Service Corporation (WSC) ended its
         affiliation with the Nationwide Insurance Enterprise and employees of
         WSC ended participation in the plan. A curtailment gain of $67.1
         million resulted (consisting of a $107.2 million reduction in the
         projected benefit obligation, net of the write-off of the $40.1 million
         remaining unamortized transition obligation related to WSC). The
         Company anticipates that the plan will settle the obligation related to
         WSC employees with a transfer of assets during 1999.

         For the postretirement benefit plan as a whole, a one percentage point
         increase or decrease in the assumed health care cost trend rate would
         have no impact on the APBO as of December 31, 1998 and have no impact
         on the NPPBC for the year ended December 31, 1998.

(9)      Shareholder's Equity, Regulatory Risk-Based Capital, Retained Earnings
         ----------------------------------------------------------------------
         and Dividend Restrictions
         -------------------------

         Ohio, NLIC's and NLAIC's state of domicile, imposes minimum risk-based
         capital requirements that were developed by the NAIC. The formulas for
         determining the amount of risk-based capital specify various weighting
         factors that are applied to financial balances or various levels of
         activity based on the perceived degree of risk. Regulatory compliance
         is determined by a ratio of the company's regulatory total adjusted
         capital, as defined by the NAIC, to its authorized control level
         risk-based capital, as defined by the NAIC. Companies below specific
         trigger points or ratios are classified within certain levels, each of
         which requires specified corrective action. NLIC and NLAIC each exceed
         the minimum risk-based capital requirements.

         The statutory capital and surplus of NLIC as of December 31, 1998, 1997
         and 1996 was $1.32 billion, $1.13 billion and $1.00 billion,
         respectively. The statutory net income of NLIC for the years ended
         December 31, 1998, 1997 and 1996 was $171.0 million, $111.7 million and
         $73.2 million, respectively.

         The Company is limited in the amount of shareholder dividends it may
         pay without prior approval by the Department. As of December 31, 1998,
         the maximum amount available for dividend payment from the Company to
         its shareholder without prior approval of the Department was $71.0
         million.

         In addition, the payment of dividends by NLIC may also be subject to
         restrictions set forth in the insurance laws of New York that limit the
         amount of statutory profits on NLIC's participating policies (measured
         before dividends to policyholders) that can inure to the benefit of the
         Company and its shareholder.

         The Company currently does not expect such regulatory requirements to
         impair its ability to pay operating expenses and shareholder dividends
         in the future.

(10)     Transactions With Affiliates
         ----------------------------

         As part of the restructuring described in note 1, NLIC paid a dividend
         valued at $485.7 million to Nationwide Corp. on January 1, 1997
         consisting of the outstanding shares of common stock of ELICW, National
         Casualty Company (NCC) and West Coast Life Insurance Company (WCLIC).
         Also, on February 24, 1997, NLIC paid a dividend to NFS, and NFS paid
         an equivalent dividend to Nationwide Corp., consisting of securities
         having an aggregate fair value of $850.0 million. The Company
         recognized a gain of $14.4 million on the transfer of securities.

         The Company leases office space from NMIC and certain of its
         subsidiaries. For the years ended December 31, 1998, 1997 and 1996, the
         Company made lease payments to NMIC and its subsidiaries of $8.0
         million, $8.4 million and $9.1 million, respectively.

         Pursuant to a cost sharing agreement among NMIC and certain of its
         direct and indirect subsidiaries, including the Company, NMIC provides
         certain operational and administrative services, such as sales support,
         advertising, personnel and general management services, to those
         subsidiaries. Expenses covered by this agreement are subject to
         allocation among NMIC, the Company and other affiliates. Amounts
         allocated to the Company were $95.0 million, $85.8 million and $101.6
         million in 1998, 1997 and 1996, respectively. The allocations are based
         on techniques and procedures in accordance with insurance regulatory
         guidelines. Measures used to allocate expenses among companies include
         individual employee estimates of time spent, special cost studies,
         salary expense, commissions expense and other methods agreed to by the
         participating companies that are within industry guidelines and
         practices. The Company believes these allocation methods are
         reasonable. In addition, the Company does not believe that expenses
         recognized under the inter-company agreements are materially different
         than expenses that would have been recognized had the Company operated
         on a stand alone basis. Amounts payable to NMIC from the Company under
         the cost sharing agreement were $31.9 million and $20.5 million as of
         December 31, 1998 and 1997, respectively.

         The Company also participates in intercompany repurchase agreements
         with affiliates whereby the seller will transfer securities to the
         buyer at a stated value. Upon demand or a stated period, the securities
         will be repurchased by the seller at the original sales price plus a
         price differential. Transactions under the agreements during 1998 and
         1997 were not material. The Company believes that the terms of the
         repurchase agreements are materially consistent with what the Company
         could have obtained with unaffiliated parties.

         Intercompany reinsurance agreements exist between NLIC and,
         respectively, NMIC and ELICW whereby all of NLIC's accident and health
         and group life insurance business is ceded on a modified coinsurance
         basis. NLIC entered into the reinsurance agreements during 1996 because
         the accident and health and group life insurance business was unrelated
         to the Company's long-term savings and retirement products.
         Accordingly, the accident and health and group life insurance business
         has been accounted for as discontinued operations for all periods
         presented. Under modified coinsurance agreements, invested assets are
         retained by the ceding company and investment earnings are paid to the
         reinsurer. Under the terms of the Company's agreements, the investment
         risk associated with changes in interest rates is borne by ELICW or
         NMIC, as the case may be. Risk of asset default is retained by the
         Company, although a fee is paid by ELICW or NMIC, as the case may be,
         to the Company for the Company's retention of such risk. The agreements
         will remain in force until all policy obligations are settled. However,
         with respect to the agreement between NLIC and NMIC, either party may
         terminate the contract on January 1 of any year with prior notice. The
         ceding of risk does not discharge the original insurer from its primary
         obligation to the policyholder. The Company believes that the terms of
         the modified coinsurance agreements are consistent in all material
         respects with what the Company could have obtained with unaffiliated
         parties. Amounts ceded to NMIC and ELICW for the years ended December
         31, 1998, 1997 and 1996 were:

</TABLE>

         The Company and various affiliates entered into agreements with
         Nationwide Cash Management Company (NCMC), an affiliate, under which
         NCMC acts as a common agent in handling the purchase and sale of
         short-term securities for the respective accounts of the participants.
         Amounts on deposit with NCMC were $248.4 million and $211.0 million as
         of December 31, 1998 and 1997, respectively, and are included in
         short-term investments on the accompanying consolidated balance sheets.

         Certain annuity products are sold through three affiliated companies,
         which are also subsidiaries of NFS. Total commissions and fees paid to
         these affiliates for the three years ended December 31, 1998 were $60.0
         million, $66.1 million and $76.9 million, respectively.

(11)     Bank Lines of Credit
         --------------------

         In August 1996, NLIC, along with NMIC, entered into a $600.0 million
         revolving credit facility which provides for a $600.0 million loan over
         a five year term on a fully revolving basis with a group of national
         financial institutions. The credit facility provides for several and
         not joint liability with respect to any amount drawn by either NLIC or
         NMIC. NLIC and NMIC pay facility and usage fees to the financial
         institutions to maintain the revolving credit facility. All previously
         existing line of credit agreements were canceled. In September 1997,
         the credit agreement was amended to include NFS as a party to and
         borrower under the agreement. As of December 31, 1998 the Company had
         no amounts outstanding under the agreement.

(12)     Contingencies
         -------------

         On October 29, 1998, the Company and certain of its affiliates were
         named in a lawsuit filed in the Common Pleas Court of Franklin County,
         Ohio related to the sale of deferred annuity products for use as
         investments in tax-deferred contributory retirement plans (Mercedes
         Castillo v. Nationwide Financial Services, Inc., Nationwide Life
         Insurance Company and Nationwide Life and Annuity Insurance Company).
         The plaintiff in such lawsuit seeks to represent a national class of
         the Company's customers and seeks unspecified compensatory and punitive
         damages. The Company is currently evaluating this lawsuit, which is in
         an early stage and has not been certified as a class. The Company
         intends to defend this lawsuit vigorously.

(13)     Segment Information
         -------------------

         The Company uses differences in products as the basis for defining its
         reportable segments. The Company reports three product segments:
         Variable Annuities, Fixed Annuities and Life Insurance.

         The Variable Annuities segment consists of annuity contracts that
         provide the customer with the opportunity to invest in mutual funds
         managed by independent investment managers and the Company, with
         investment returns accumulating on a tax-deferred basis. The Company's
         variable annuity products consist almost entirely of flexible premium
         deferred variable annuity contracts.

         The Fixed Annuities segment consists of annuity contracts that generate
         a return for the customer at a specified interest rate, fixed for a
         prescribed period, with returns accumulating on a tax-deferred basis.
         Such contracts consist of single premium deferred annuities, flexible
         premium deferred annuities and single premium immediate annuities. The
         Fixed Annuities segment includes the fixed option under variable
         annuity contracts.

         The Life Insurance segment consists of insurance products, including

 (14)    Discontinued Operations
         -----------------------

         As discussed in note 1, NFS is a holding company for NLIC and certain
         other companies within the Nationwide Insurance Enterprise that offer
         or distribute long-term savings and retirement products. Prior to the
         contribution by Nationwide Corp. of the outstanding common stock of
         NLIC to NFS, NLIC effected certain transactions with respect to certain
         subsidiaries and lines of business that were unrelated to long-term
         savings and retirement products.

         On September 24, 1996, NLIC's Board of Directors declared a dividend
         payable to Nationwide Corp. on January 1, 1997 consisting of the
         outstanding shares of common stock of three subsidiaries: ELICW, NCC
         and WCLIC. ELICW writes group accident and health and group life
         insurance business and maintains it offices in Wausau, Wisconsin. NCC
         is a property and casualty company with offices in Scottsdale, Arizona
         that serves as a fronting company for a property and casualty
         subsidiary of NMIC. WCLIC writes high dollar term life insurance
         policies and is located in San Francisco, California. ELICW, NCC and
         WCLIC have been accounted for as discontinued operations in the
         accompanying consolidated financial statements through December 31,
         1996. The Company did not recognize any gain or loss on the disposal of
         these subsidiaries.

         Also, during 1996, NLIC entered into two reinsurance agreements whereby
         all of NLIC's accident and health and group life insurance business was
         ceded to ELICW and NMIC, effective January 1, 1996. See note 10 for a
         complete discussion of the reinsurance agreements. The Company has
         discontinued its accident and health and group life insurance business
         and in connection therewith has entered into reinsurance agreements to
         cede all existing and any future writings to other affiliated
         companies. NLIC's accident and health and group life insurance business
         is accounted for as discontinued operations for all periods presented.
         The Company did not recognize any gain or loss on the disposal of the
         accident and health and group life insurance business. The assets,
         liabilities, results of operations and activities of discontinued
         operations are distinguished physically, operationally and for
         financial reporting purposes from the remaining assets, liabilities,
         results of operations and activities of the Company.

         A summary of the results of operations of discontinued operations for
         the years ended December 31, 1998, 1997 and 1996 is as follows:

Item 27.      NUMBER OF CONTRACT OWNERS

              N/A

Item 28.      INDEMNIFICATION
              Provision is made in Nationwide's Amended and Restated Code of
              Regulations and expressly authorized by the General Corporation
              Law of the State of Ohio, for indemnification by Nationwide of any
              person who was or is a party or is threatened to be made a party
              to any threatened, pending or completed action, suit or
              proceeding, whether civil, criminal, administrative or
              investigative by reason of the fact that such person is or was a
              director, officer or employee of Nationwide, against expenses,
              including attorneys fees, judgments, fines and amounts paid in
              settlement actually and reasonably incurred by such person in
              connection with such action, suit or proceeding, to the extent and
              under the circumstances permitted by the General Corporation Law
              of the State of Ohio. Insofar as indemnification for liabilities
              arising under the Securities Act of 1933 ("Act") may be permitted
              to directors, officers or persons controlling Nationwide pursuant
              to the foregoing provisions, Nationwide has been informed that in
              the opinion of the Securities and Exchange Commission such
              indemnification is against public policy as expressed in the Act
              and is, therefore, unenforceable. In the event that a claim for
              indemnification against such liabilities (other than the payment
              by the registrant of expenses incurred or paid by a director,
              officer or controlling person of the registrant in the successful
              defense of any action, suit or proceeding) is asserted by such
              director, officer or controlling person in connection with the
              securities being registered, the registrant will, unless in the
              opinion of its counsel the matter has been settled by controlling
              precedent, submit to a court of appropriate jurisdiction the
              question whether such indemnification by it is against public
              policy as expressed in the Act and will be governed by the final
              adjudication of such issue.

Item 29.      PRINCIPAL UNDERWRITER
