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.

EXAMPLE

The following chart shows the amount of expenses (in dollars) that would be
incurred under the contracts assuming a $1,000 investment, 5% annual return, and
no change in expenses. These dollar figures are illustrative only and should not
be considered a representation of past or future expenses. Actual expenses may
be greater or less than those shown below.

The example reflects expenses of both the variable account and the underlying
mutual funds. Deductions for premium taxes are not reflected but may apply. The
example reflects the 5 year CDSC schedule and the maximum Variable Account
Annual Expense Fee (0.95%). The example reflects the Contract Maintenance
Charge, expressed as a percentage of average account value. Since the average
contract value is greater than $1,000, the expense effect of the Contract
Maintenance Charge is reduced accordingly.

For those contracts that have a different CDSC schedule or a lower Variable
Account Annual Expense Fee, the expenses would be reduced.

The summary of contract expenses and example are to help contract owners
understand expenses associated with the contracts.

CONDENSED FINANCIAL INFORMATION

The accumulation unit value for each underlying mutual fund reflects changes in
the value of the underlying mutual fund and the deduction of the Variable
Account Annual Expense Fee. For specific accumulation unit value information for
each class of the underlying mutual funds, please refer to Appendix B.

FINANCIAL STATEMENTS

Financial Statements for the variable account and 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 located on page 2 of this prospectus.

SYNOPSIS OF THE CONTRACTS

The contracts are group flexible fund retirement contracts. The contracts are
designed for use in deferred compensation plans adopted by member counties under
the NACo program. The plans qualify for favorable tax treatment under Section
457 of the Internal Revenue Code.

Nationwide issues a single group contract to the contract owner, which covers
all present and future participating employees. Nationwide will provide a
certificate to the contract owner to deliver to each retired participant or
other person for whom a Retirement Income Form is purchased. The certificate
will set forth the benefits to which the recipient is entitled. Additionally, if
legally required, Nationwide will provide a certificate to the contract owner
for delivery to any other person required by law to receive a certificate.

Nationwide establishes an account for each participant under the contract. The
account contains values and reflects activity for each participant. Plan
participants generally receive tax deferral on amounts deposited into the plan
and are taxed when amounts are distributed from the plan.

                                       10

                                   12 of 161
<PAGE>   13

Purchase payments are normally submitted monthly, but the schedule may be
adjusted to fit the contract owner's payroll practices. Purchase payments made
by or on behalf of each participant must be at least $20 per month.

The contract strives to provide each participant with:

- -    an initial Retirement Income Payment, which will reflect cost of living
     changes during pre-retirement years (without requiring increased purchase
     payments to keep pace with cost of living increases during those years),
     and

- -    subsequent Retirement Income Payments which will vary with the cost of
     living changes during his or her retired lifetime.

   
Although the contract strives to achieve its goals, there can be no assurance
that the contracts will achieve them.
    

Nationwide will apply purchase rates set forth in the contract to accumulated
amounts in participant accounts. These accumulated amounts will reflect the
investment performance of the underlying mutual funds selected by the
participant. Consequently, a participant's Retirement Income Payments will be
directly affected by his or her investment choices under the contract.
Historically, the value of a diversified portfolio of common stocks held for an
extended period of time has tended to rise during periods of inflation. However,
there is no exact correlation and for some periods, the prices of securities
have declined while the cost of living was rising.

MINIMUM PURCHASE PAYMENTS

Purchase payments for each participant must be at least $20 per month.

CHARGES AND EXPENSES

   
Nationwide does not deduct a sales charge from purchase payments upon deposit
into the contract. However, Nationwide may deduct a CDSC if any amount is
withdrawn from the contract. This CDSC reimburses Nationwide for sales expenses.
The amount of the CDSC will not exceed 5% of purchase payments surrendered.
    

Nationwide may assess a Participant Account Maintenance Charge. This charge
varies from contract to contract and will not be assessed unless specifically
agreed upon by the contract owner and Nationwide. The maximum Participant
Account Maintenance Charge is $50 (see "Participant Account Maintenance
Charge").

Nationwide can deduct a Variable Account Annual Expense Fee at a maximum rate of
0.95% of average account value. Nationwide can assess this fee in return for
bearing certain risks and administrative expenses. The Variable Account Annual
Expense Fee is negotiable and varies from contract to contract to reflect unique
plan characteristics. This fee does not reflect deductions made by the
underlying mutual funds (see "Variable Account Annual Expense Fee").

The CDSC, Participant Account Maintenance Charge, and Variable Account Annual
Expense Fee, when negotiated, may be decreased upon notice to the contract owner
(see "Modification of the Contract").

RETIREMENT INCOME PAYMENTS

Retirement income payments begin on the annuitzation date. Payments are based on
the retirement income form chosen (see "Retirement Income Payments" and
"Retirement Income Forms").

TAXATION

How the contracts are taxed depends on the type of contract issued. Nationwide
will charge against the contract any premium taxes levied by any governmental
authority (see "Federal Tax Considerations" and "Premium Taxes").

NATIONWIDE LIFE INSURANCE COMPANY

Nationwide is a stock life insurance company organized under Ohio law in March,
1929. Nationwide is a member of the "Nationwide

                                    13 of 161
<PAGE>   14

Insurance Enterprise" with its home office at One Nationwide Plaza, Columbus,
Ohio 43215. 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.

NATIONWIDE INVESTMENT SERVICES CORPORATION

The contracts are underwritten and distributed by Nationwide Investment Services
Corporation ("NISC"), Two Nationwide Plaza, Columbus, Ohio 43215. NISC is a
wholly owned subsidiary of Nationwide Life Insurance Company.

INVESTING IN THE CONTRACT

THE VARIABLE ACCOUNT AND UNDERLYING MUTUAL FUNDS

The variable account is a separate account that invests in the underlying mutual
funds listed in Appendix A. Nationwide established the variable account on
September 7, 1988, 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 it or the
management of Nationwide.

Income, gains, and losses credited to, or charged against, the variable account
reflect the variable account's own 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.

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 

                                       12

                                   14 of 161

<PAGE>   15

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.

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 another underlying
mutual fund 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.

STANDARD CHARGES AND DEDUCTIONS

The charges and fees described in this section vary from contract to contract,
depending on plan characteristics and the particular needs and preferences of
contract owners. Generally, the charges and fees are negotiable. This
flexibility allows Nationwide and the contract owner to custom design a charge
structure that meets the financial goals of both the contract owners and
Nationwide.

While a contract is in effect, a circumstance may arise that would require a
renegotiation of the contract terms. In this situation, charges and fees will
not be higher than those in effect before the re-negotiation. In other words,
the charges and fees of a renegotiated contract may decrease, but under no
circumstances will they increase.

PARTICIPANT ACCOUNT MAINTENANCE CHARGE

Nationwide may assess a Participant Account Maintenance Charge to reimburse it
for administrative expenses involved in issuing and maintaining the contracts.
The maximum Participant Account Maintenance Charge is $50. Nationwide will not
assess this charge unless it is negotiated and contractually agreed upon by
Nationwide and the contract owner.

Generally, by negotiating a higher Participant Account Maintenance Charge, a
contract owner can expect to lower other charges that are assessed in connection
with the contract. Conversely, a contract owner that negotiates a lower
Participant Account Maintenance Charge can expect to incur higher charges
elsewhere in the expense structure.

If a Participant Account Maintenance Charge is negotiated, it will be assessed
against each applicable participant in the plan. Nationwide will deduct the
charge from each participant's account on the participant anniversary, which is

                                       13

                                   15 of 161
<PAGE>   16

the anniversary of the date accumulation units were first credited to the
participant's account. Each year's deduction will compensate Nationwide for
expenses incurred during the previous year. The deduction will occur during both
the accumulation and annuity payment periods.

The Participant Account Maintenance Charge is made by canceling a number of
accumulation units during both the accumulation and annuity periods, equal in
value to the applicable charge. If a participant account includes more than one
sub-account, the deduction will be allocated among sub-accounts on the basis of
relative values at the time the deduction is made.

On the date that a full withdrawal is taken from a participant's account,
Nationwide will deduct a pro-rated Participant Account Maintenance Charge. The
amount of the charge will be 1/12 of the applicable Participant Account
Maintenance Charge, multiplied by the number of whole or partial months between
the last participant anniversary (or participant effective date during the first
year of a participant account) and the withdrawal date.

The deduction for the Participant Account Maintenance Charge will be taken
proportionately from each sub-account based on relative value at the time the
deduction is made.

This contract may be used by a plan in conjunction with other investment
options, such as Nationwide's Group Fixed Fund Retirement Contract. In this
case, the deduction for the Participant Account Maintenance Charge may be
reduced so that the combined total of the Participant Account Maintenance Charge
and any similar charges imposed under other investment options does not exceed
the Participant Account Maintenance Charge negotiated for this contract. The
charge will be deducted proportionately from the sub-accounts and amounts held
in the other investment options based on the relative values at the time the
deduction is made.

THE PARTICIPANT ACCOUNT MAINTENANCE CHARGE WILL NOT BE ASSESSED UNLESS
NEGOTIATED BETWEEN NATIONWIDE AND THE CONTRACT OWNER.

VARIABLE ACCOUNT ANNUAL EXPENSE FEE

Nationwide can deduct a Variable Account Annual Expense Fee up to a maximum rate
of 0.95% of average account value in exchange for assuming various risks and
administrative expenses associated with the contracts. This fee is subject to
negotiation and can vary for each contract to reflect unique plan
characteristics.

The following factors may be considered in negotiating the amount of this fee:

   1) plan size;

   2) the number of eligible employees;

   3) the number of plan participants;

   4) demographics of the plan participants;

   5) general economic conditions;

   6) the varying costs associated with the underlying mutual funds that are
      offered in the contract;

   7) the type of contract (e.g. allocated vs. unallocated);

   8) distribution costs; and

   9) other factors that Nationwide deems relevant.

CONTINGENT DEFERRED SALES CHARGE

No sales charge is deducted from purchase payments when amounts are deposited
into the contracts. However, if any part of the contract is surrendered,
Nationwide will deduct a CDSC when applicable. The CDSC is used to cover sales
expenses, including commissions, production of sales material, and other
promotional expenses. If expenses are greater than the CDSC, Nationwide will
make up any shortfall from its general account.

Regardless of the CDSC schedule chosen, no CDSC will be assessed against
distributions paid as:

   -  a life income payment option;

                                       14

                                   16 of 161

<PAGE>   17

   -  a designated period payment option of 5 or more years for a participant
      who has a minimum of 5 participant account years before the beginning of
      the benefit payments; and

   -  a single-sum or periodic payment resulting from a participant's death.

   
Contracts Issued Beginning July 1, 1985 and Before May 1, 1998
    

If the contract owner terminates the contract in accordance with the section
entitled "Suspension and Termination" and directs Nationwide to withdraw all or
part of the contract value, Nationwide will assess a CDSC from each
participant's account as indicated below. For purposes of calculating the CDSC,
withdrawals are considered to come first from the oldest purchase payment made
to the contract, then the next oldest purchase payment, and so forth.

   
The following CDSC schedule applies to contracts issued beginning July 1, 1985
and before the later of May 1, 1998 or the date on which state insurance
authorities approve contract modifications.

In any event, no CDSC will be assessed against withdrawals taken on or after
January 1, 2001 for contracts issued beginning July 1, 1985 and before the later
of May 1, 1998 or the date on which state insurance authorities approve contract
modifications.

When a CDSC of less than 4% is negotiated and assessed, the reduced charge may
reflect actual variations in expenses, usually resulting from reduced expenses
to Nationwide in connection with case acquisition costs, plan start-up expenses,
commissions and marketing expenses. Nationwide will not apply any deductions in
a discriminatory manner.
    

Contracts Issued On or After May 1, 1998

For contracts issued on or after the later of May 1, 1998 or the date on which
state insurance authorities approve contract modifications, a CDSC may be
negotiated and assessed.

The total CDSC assessed to any participant will never exceed 5% (or a lesser
percentage, if applicable) of the total purchase payments made on behalf of the
participant for the 16 years before the surrender date.

   
When a CDSC of less than 5% is negotiated and assessed, the reduced charge may
reflect actual variations in expenses, usually resulting from reduced expenses
to Nationwide in connection with case acquisition costs, plan start-up expenses,
commissions and marketing expenses. Nationwide will not apply any deductions in
a discriminatory manner.
    

PREMIUM TAXES

Nationwide may 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 RIGHTS

The contract owner owns the contract for the exclusive benefit of the plan's
participants and beneficiaries. Contractual rights may be exercised by the
contract owner subject to those rights 

                                       15

                                   17 of 161

<PAGE>   18

specifically reserved in the plan documents for participants, either as a group
or as individuals. The contract owner may not take any action inconsistent with
the rights of the plan's participants. The contract may not be assigned.

OPERATION OF THE CONTRACT

MINIMUM PURCHASE PAYMENTS

Purchase payments for each participant must be at least $20 per month. Payments
must be made no less frequently than monthly, unless Nationwide agrees
otherwise.

APPLICATION OF PURCHASE PAYMENTS

   
Initial purchase payments allocated to sub-accounts will be priced at the
accumulation unit value determined no later than 2 business days after receipt
of an order to purchase if the application and all necessary information are
complete. If the application is not complete, Nationwide may retain a purchase
payment for up to 5 business days while attempting to complete it. If the
application is not completed within 5 business days, the participant will be
informed of the reason for the delay. The purchase payment will be returned
unless the participant specifically allows Nationwide to hold the purchase
payment until the application is completed.
    

Subsequent purchase payments will be priced based on the next available
accumulation unit value after the payment is received.

   
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, account value may be affected since the contract owner would
not have access to their account.
    

When permissible under state insurance law, Nationwide may credit up to 8% of an
initial transfer into the contract. An initial transfer is the amount
transferred into the contract from a non-Nationwide investment product. It
serves as the initial purchase payment under the contract. This credit will
reimburse the contract owner for any exit penalty assessed by the previous
provider. Nationwide will recover this credit by reducing service agent and/or
broker compensation or through the negotiation of an increased Participant
Account Maintenance Charge or Variable Account Annual Expense Fee.

ALLOCATION OF PURCHASE PAYMENTS

   
Nationwide allocates purchase payments to each participant's account as
instructed by the contract owner. Shares of the underlying mutual funds
allocated to the sub-accounts are purchased at net asset value, then converted
into accumulation units. The contract owner, or the participant if the plan so
permits, may change allocations among sub-accounts for future purchase payments.
However, no change may be made that would result in an amount less than 1% of
the purchase payments being allocated to any sub-account for any participant.
Nationwide will accept these changes as frequently as permitted by the plan. An
allocation change will not affect the allocation of purchase payments before the
change.

DETERMINING VARIABLE ACCOUNT VALUE - VALUING AN ACCUMULATION UNIT

Purchase payments or transfers allocated to sub-accounts are accounted for in
accumulation 
    

                                       16

                                   18 of 161

<PAGE>   19

   
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, which may
       include charges for contract options chosen by the contract owner. The
       factor is equal to an annual rate ranging from 0.00% to 0.95% of the
       daily net assets of the variable account, depending on which contract
       features the plan has chosen.

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 THE PARTICIPANT ACCOUNT VALUE
    

A participant's account value is equal to the sum of the value of all
accumulation units credited to the participant's account. The number of
accumulation units credited to each participant account for each sub-account is
determined by dividing the amount allocated to that sub-account for that
participant by the accumulation unit value for that sub-account for the
valuation period the purchase payment was received.

The value of a participant's account on any day can be determined by multiplying
the total number of accumulation units credited to the participant's account for
each sub-account by the current accumulation unit value for that sub-account.
Each participant and the contract owner will be advised periodically of the
number of accumulation units credited to his or her account for each
sub-account, the current accumulation unit values, and the total value of his or
her account. These reports are for informational purposes only and do not mean
that a participant has any rights in his or her account beyond those provided
for in the plan.

EXCHANGE PRIVILEGE

   
The contract owner, or the participant if the plan so provides, may exchange
amounts among the sub-accounts as frequently as permitted by the plan, subject
to the limits and rules set by each underlying mutual fund. Certain plans may
impose limitations on participant exchange privileges as a consequence of
agreements entered into to purchase mutual funds or other investments unrelated
to the contract. If the contract owner elects an exchange privilege, there is no
charge for exchanges.
    

For those plans funded by this contract and Nationwide's Group Fixed Fund
Retirement 

                                       17

                                   19 of 161


<PAGE>   20

Contract, the contract owner, or the participant if the plan so provides, may
exchange values between any sub-account and the Group Fixed Fund Retirement
Contract. Exchanges from the Nationwide Group Fixed Fund Retirement Contract to
any sub-account will be subject to the limitations of the Nationwide Group Fixed
Fund Retirement Contract. Exchanges will be effective when received in good
order at Nationwide's home office.

If Nationwide receives the exchange request before the end of a valuation date,
the exchange will receive the accumulation unit values of that date. However, if
Nationwide receives the exchange request after the close of business on a
valuation date, the exchange will receive the next valuation date's accumulation
unit value.

   
EXCHANGE REQUESTS
    

In addition to submitting exchange requests in writing, the participant may also
make exchanges by telephone and the internet, provided that the contract owner
executes documents agreeing to certain restrictions applicable to these
privileges. Telephone and internet exchange requests must be received by
Nationwide by the close of the New York Stock Exchange in order to receive that
day's closing sub-account price.

   
Nationwide will use reasonable procedures to confirm that telephone and internet
instructions are genuine and will not be liable for following telephone or
internet instructions that it reasonably determined to be genuine. Nationwide
may withdraw the telephone and/or internet exchange privilege upon 30 days
written notice to contract owners and participants.
    

EXPERIENCE CREDITS

Depending on the state in which the contract was issued, the contracts are
either participating or non-participating. Contract owners of participating
contracts have the right to receive any surplus distributed by Nationwide. A
surplus distribution will occur if Nationwide's Board of Directors determines
that charges and fees assessed under the contracts were higher than necessary to
maintain the contracts. Nationwide will distribute any surplus by purchasing
additional accumulation units and crediting them to participant accounts. To
date, Nationwide has not made any surplus distributions to participant accounts
and Nationwide does not guarantee that there will be a surplus distribution in
the future. Non-participating contracts do not have the right to receive surplus
distributions.

MODIFICATION OF THE CONTRACT

The following charges may be decreased if negotiated, upon notice to the
contract owner:

   -  Contingent Deferred Sales Charge

   -  Participant Account Maintenance Charge

   -  Variable Account Annual Expense Fee

   
No modifications may be made prior to the first contract anniversary.
    

Nationwide may change any other provision of the contract by giving notice to
contract owners not less than 90 days before the change is to be effective.

CONTRACT SUSPENSION AND TERMINATION

Nationwide may suspend the contract at any time upon written notice to contract
owners if:

   a)    the contract owner fails to remit to Nationwide any purchase payment 
         specified in the plan;

   b)    Nationwide rejects a plan amendment submitted by the contract owner
         that Nationwide determines would adversely affect the contract's
         financial experience.

The contract owner may suspend the contract at any time upon 90 days written
notice to Nationwide. Suspension will become effective on the 91st day after
Nationwide receives the notice. If a contract is suspended, Nationwide will not
accept new purchase payments, except by mutual consent. All other contract terms
will continue to apply.

Once the suspension is effective, the contract owner may, upon 30 days written
notice to Nationwide, terminate the contract. Termination will become effective
on the 31st day after 

                                       18

                                   20 of 161
<PAGE>   21

Nationwide receives the notice. Upon termination, Nationwide will pay to the
contract owner:

   1)  the redemption value of participant accounts, less any applicable 
       CDSC; and

   2)  the balance of the annual payment amounts in Nationwide's General Account
       transferred to make Retirement Income Payments under Retirement Income
       Forms B1 and B2.

REDEMPTION OF PARTICIPANT ACCOUNTS

The contract owner's right to redeem participant accounts, either fully or
partially, will be governed by the terms of the plan.

   
If the plan so permits, the contract owner may redeem a participant account,
fully or partially, at any time before Retirement Income Payments begin under
Option B1 or B2 (see "Retirement Income Forms"). A partial redemption will not
affect requirements to make future purchase payments to that participant account
or that participant's retirement date.
    

For partial redemptions, Nationwide will cancel accumulation units from the
sub-accounts. The requested dollar amount cannot exceed available accumulation
unit value. The contract owner must instruct Nationwide how the redemption
should be taken from the sub-accounts. If no instruction is given, the
redemption will be taken proportionately from each sub-account based on the
value of each sub-account at the time of the redemption.

Instead of a lump sum distribution of a full or partial redemption, the contract
owner (or participant, if permitted by the plan) may elect to have the
redemption paid pursuant to Retirement Income Form A1 or A2, subject to the
minimums applicable to these options.

If the contract owner terminates the contract, all participant accounts under
that contract will be redeemed as permitted by the plan. A CDSC may apply.
However, absent contract termination, no CDSC will apply to full or partial
redemptions.

Nationwide will pay all redemption amounts to the contract owner. The contract
owner is obligated to distribute these amounts to the participant. The contract
owner and Nationwide may agree to have Nationwide pay these amounts directly to
the participant.

Nationwide will pay any redemption amounts within 7 days of receiving the
redemption request. However, Nationwide may suspend or postpone payment when:

   (1) the New York Stock Exchange is closed;

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

   (3) an emergency is declared by the SEC making disposal or valuation of
       securities held in the variable account impracticable; or

   (4) 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 and/or
participant would not have access to their account.
    

Participant account value upon full surrender may be more or less than the total
of all purchase payments.

RETIREMENT PERIOD

ADDITIONAL PURCHASE PAYMENT BEFORE BEGINNING RETIREMENT INCOME PAYMENTS

The contract owner may make one additional purchase payment to each
participant's account in order to increase Retirement Income Payments. The
contract owner must notify Nationwide of this election in the documentation
electing the Retirement Income Form and retirement date (see "Election of
Retirement Income Form and Date"). The purchase payment must be made by the last
business day before Retirement Income Payments 

                                       19

                                   21 of 161
<PAGE>   22

begin. This purchase payment is subject to any applicable premium taxes.

The annuity rates under the contract apply to the entire value, including any
such additional purchase payment that does not exceed 5 times the purchase
payments allocated to a participant's account before the date of notice is
given. Any amount in excess of this amount may be applied at annuity rates
currently offered to this type of contract.

RETIREMENT INCOME PAYMENTS

The distribution period is the period during which a participant account is paid
out in installments. Since the distribution period usually occurs after a
participant retires, it is also referred to as the retirement period.

Nationwide will pay all retirement distributions to the contract owner. The
contract owner is obligated to distribute these amounts to the participant. The
contract owner and Nationwide may agree to have Nationwide pay these amounts
directly to the participant.

Upon retirement, a participant's account value can be used to purchase either a
fixed dollar annuity, a variable payment annuity, or an available combination of
both.

Nationwide is obligated to make payments under a variable payment annuity.
However, the amount of each payment is not guaranteed. Variable payment amounts
will reflect the investment performance of the sub-accounts, but will not be
affected by adverse mortality experience or by increased expenses.

A fixed dollar annuity provides for payments that are guaranteed as to dollar
amount during the distribution period. Upon retirement, the participant's
account value is used to purchase a contract fund by Nationwide's general
account. Once this contract has been purchased, the participant's account will
no longer vary with the investment performance of the underlying mutual funds.

To determine the amount of the first fixed dollar annuity payment, the value is
applied to the applicable annuity table based on the distribution schedule
elected. The fixed payment annuity can be distributed in any of the forms listed
under the provision "Retirement Income Forms." Specifically, they can be
distributed as:

   1) payments for a designated period;

   2) payments of a designated amount;

   3) life income with payment certain; or

   4) joint and survivor life income.

Fixed dollar annuities are available under a plan upon the contract owner's
election.

ELECTION OF RETIREMENT INCOME FORM AND DATE

The contract provides for Retirement Income Payments to begin on the date and
under the retirement options set forth in the plan. At least one month before
Retirement Income Payments are set to begin, the contract owner may elect one of
the retirement income options set forth in this prospectus. Nationwide must
receive this election in writing. The plan may restrict changes in the
retirement income option elected.

If, at retirement, the present value of a participant's account is less than
$3,500, Nationwide may make a lump sum distribution instead of periodic
payments.

RETIREMENT INCOME FORMS

Retirement distributions may take any of the following forms, as permitted by
the plan:

AMOUNT AND PERIOD CERTAIN OPTIONS

     Option A1: Payments for a Designated Period

     Payments will be made monthly for a set number of years not to exceed 30
     years. The amount of each payment will vary with the performance of the
     underlying mutual funds in which the participant account invests.
     Nationwide calculates each payment by multiplying (a) by (b), where:

       (a) is the accumulation unit value on the day the payment is made; and

       (b) is the number of accumulation units applied under this option divided
           by the number of payments selected.

                                       20

                                    22 of 161
<PAGE>   23

     Once the amount of the payment is calculated, Nationwide will cancel
     available accumulation units to equal the dollar amount of that payment.

     Exchanges between the investment options are permitted subject to the
     limitations set forth in the Group Fixed Fund Retirement Contract.
     Exchanges may cause the number of accumulation units to change,
     necessitating a recalculation of the payment amount.

     If the period selected under this option is less than 5 years, and the
     participant has less than 5 participant account years, a CDSC will be
     assessed against each payment.

     Option A2: Payments of a Designated Amount

     Payments will be made monthly in equal installments of a set amount (not
     less than $25 per month) until no accumulation units remain in the
     participant account. The participant's account is adjusted each valuation
     date to reflect investment results. Nationwide will cancel accumulation
     units up to the designated dollar amount of the payment.

     Exchanges between the investment options are permitted subject to the
     limitations set forth in the Group Fixed Fund Retirement Contract.

     If election of this option results in a payment period of less than 5
     years, and the participant has less than 5 Participant Account Years, a
     CDSC will be assessed against each payment.

LIFE INCOME OPTIONS

For the following options, payments will be determined annually and will remain
level throughout the year. Each year, on the anniversary of the beginning of
Retirement Income Payments, a new monthly payment will be determined. That new
payment will remain level for that year.

Nationwide will use the retired participant's adjusted age to determine each
year's set monthly payment. This adjusted age may not be the same as the retired
participant's actual age.

Life income options are based on:

   -  the mortality tables specified in the contract;

   -  the adjusted age of the retired participant;

   -  the type of Retirement Income Payment option(s) selected; and

   -  in the case of variable payments, the investment performance of the 
      specific sub-accounts elected.

   - Option B1: Life Income with Payment Certain

     Payments will be made monthly during an individual's lifetime for a set
     period of 60, 120, 180, 240, 300 or 360 months, as elected. If the
     individual dies before the end of the selected period, level payments will
     continue to the beneficiary during the remainder of the selected period.
     Unless prohibited by the plan, the beneficiary may elect at any time to
     receive the present value of the remaining number of payments in a single
     payment, calculated using the same assumed investment rate used previously.

     Nationwide will cancel accumulation units up to the designated dollar
     amount of each payment.

     Option B2: Joint and Survivor Life Income

     Payments will be made monthly during the joint lifetime of the participant
     and a beneficiary. Payments will be made as long as either of the two is
     living. If the participant predeceases the beneficiary, payments will
     continue to be paid to the beneficiary at 100%, 75%, 66 2/3% or 50% of the
     original payment amount as elected until the beneficiary's death. If the
     beneficiary predeceases the participant, payments will continue at 100% to
     the participant.

     Nationwide will cancel accumulation units up to the designated dollar
     amount of each payment.

Other Options

Alternate distribution methods may be used with Nationwide's consent.

                                       21

                                   23 of 161
<PAGE>   24



Frequency of Payment

The retired participant, with the contract owner's consent, may receive payments
under any option annually, semi-annually, or quarterly instead of monthly. Any
change in frequency of payments must be on the anniversary of the beginning of
Retirement Income Payments.

Withdrawal

   
If allowed by the plan, any amount remaining under option A1 or A2 may be
withdrawn. If that amount is at least $5,000, the withdrawn amount may be
applied to option B1 or B2, subject to minimum payment requirements.
    

DETERMINATION OF LIFE INCOME PAYMENTS

   
The amount of annuity payments will vary depending on the performance of the
underlying mutual funds selected.

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. If not
prohibited by law, a contract owner may, at contract issuance, elect an
alternated assumed investment rate of 5% per annum. The choice of assumed
investment rate affects the pattern of Retirement Income Payments. 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 is
higher or lower than the assumed investment rate.

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 built into the variable payment annuity purchase rate basis in
the contracts.
    

First Year's Payments

To determine the monthly payment that will be distributed monthly for the first
year after retirement, Nationwide first determines the participant's account
value as of the retirement date. This value is found by multiplying the number
of accumulation units in each sub-account for that participant's account by the
accumulation unit value for that sub-account on the last business day of the
second calendar week before the date the first payment will be made.

Based on the participant's account value, Nationwide then determines the amount
of each monthly payment. The monthly payment amount is found by dividing the
accumulation unit value of that sub-account in the participant's account by the
amount required to provide $1 per month (the purchase rate).

Once the monthly payment amount is found, Nationwide multiplies the payment by
12 to get the total payment for the year. Then Nationwide cancels the number of
accumulation units from the participant's account to equal the total payments
for the year. The accumulation units will be canceled from each sub-account in
the same proportion that new purchase payments are allocated. The value is then
transferred to Nationwide's general account from which monthly payments are
made.

The total annual amount is calculated so that if there are no partial
redemptions, and no underlying mutual fund dividends are taken in cash, the
monthly payments will be level as long as the net investment factor equals the
assumed investment rate plus an amount equal to the annual administrative
charge. Payments in subsequent years will vary depending on how the
sub-accounts' performance compares to the assumed investment rate.

                                       22

                                   24 of 161

<PAGE>   25



   
Second and Subsequent Years' Payments

On each anniversary of the beginning of Retirement Income Payments, the second
year's monthly payment amount will be calculated. The calculation will be
performed in the same manner as the first year's payment, except that the
current participant account value will be used. Similarly, accumulation units
will be cancelled and the value will be transferred to Nationwide's general
account, from which monthly payments will be made. Subsequent years' payments
will be calculated in the same fashion on each anniversary date.
    

DEATH OF PARTICIPANT

PARTICIPANT DEATH BEFORE RETIREMENT

If a participant dies before beginning Retirement Income Payments, a death
benefit equal to the participant's account value is payable as set forth in the
plan. The death benefit will be paid when Nationwide:

     1) receives and verifies the participant's death; and

     2) verifies beneficiary designations.

If the plan so provides, the beneficiary may receive the death benefit:

     1) as a lump sum; or

     2) in the form of a Retirement Income Form contained in the contract,
        subject to applicable minimums. Retirement Income Payments may be
        fixed, variable, or a combination of both.

DEATH OF RETIRED PARTICIPANT

If a retired participant dies while receiving payments, any payment due will be
determined according to the Retirement Income Form elected. The calculation of
the net present value of any remaining payments under a period certain option
will be based on the same assumed investment rated used in determining the
payments before the retired participant's death.

The participant account will be reduced by the number of accumulation units not
required to provide further payments during the remainder of a period certain,
if any, or to a contingent retired participant. Depending on Nationwide's
obligation under the contract, the accumulation units will either remain in the
variable account or be transferred to Nationwide's general account.

FEDERAL TAX CONSIDERATIONS

Consult a financial adviser, legal counsel or tax advisor 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. The contracts are treated as a trust under
rules similar to Internal Revenue Code Section 401(f).

Under existing federal income tax law, Nationwide is not required to pay taxes
on the variable account's investment income when it is credited to contract
owners. Nationwide is taxed as a life insurance company under Part One,
Subchapter L of the Internal Revenue Code.

Contract owners would normally be taxed on income and capital gains earned under
the contract, whether or not taken in cash. However, the contracts are issued
only to organizations exempt from federal income tax.

Distributions will normally contain purchase payments that were not previously
included in the participant's gross income. Upon distribution, these amounts
should be included in the gross income of the recipient.

The contract owner is responsible for ensuring that the plan is established and
administered in accordance with the provisions set forth in the Internal Revenue
Code.

CONTRACTS ISSUED UNDER THE NEW YORK MODEL PLAN

In order to sell the contracts to governmental employers in the state of New
York, the following amendments must be made to the contract:

   - The "Suspension and Termination" provision is amended to allow a
     participant to "freeze" his or her account and maintain the account on
     deposit with Nationwide even though the contract was terminated. The
     contract owner will continue to own the account, subject to the claims of
     its general creditors.

STATEMENTS AND REPORTS

   
Nationwide (or a designee) will provide each participant a Statement of Assets,
Liabilities and Contract Owners' Equity and a Statement of Operations and
Changes in Contract Owners' Equity for the variable account at least
semi-annually. Nationwide will also provide 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.
    

Additionally, each participant and retired participant will receive periodic
reports on the value of his or her account.

Participants should review these reports 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 report,
Nationwide will assume all transactions are correct.

Nationwide will provide contract owners with the variable account's prospectus
to make available to participants. The contract owner may, under the terms of
the plan, be required to provide additional information to participants, such as
changes in the plan, changes in the tax status of the plan, or the financial
condition of the contract owner as it relates to obligations under the plan.

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 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 impelemented 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. Conversions of existing
traditional life policies will continue through second quarter, 1999. In
addition, the shareholder services system that supports our mutual fund products
will be fully deployed in the first quarter of 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 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 including electronic interfaces. Processes
have been put into place and programs initiated to process data irrespective 
    

                                       24

                                   26 of 161

of the format by converting non-compliant data into a Year 2000 compliant
format.

Systems supporting Nationwide's infrastructure such as telecommunications, voice
and networks will be compliant by March 1999. Nationwide's assessment of Year
2000 issues has also included non-information technology systems with embedded
computer chips. Nationwide's building systems such as fire, security, and
elevators and escalators supporting facilities in Columbus, Ohio have been
tested and are Year 2000 compliant.

In addition to resolving internal Year 2000 readiness issues, Nationwide is
surveying significant external organizations (business partners) to assess if
they will be Year 2000 compliant and be in a position to do business in the Year
2000 and beyond. Specifically, nationwide has contacted mutual fund
organizations that provide funds for our variable annuity and life products. The
same action will continue during the first quarter of 1999 with wholesale
producers. Nationwide continues its efforts to identify external risk factors
and is planning to develop contingency plans as part of its ongoing risk
management strategy.

Operating expenses in 1998 and 1997 included 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. 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 February 1997, Nationwide was named as a defendant in a lawsuit filed in New
York state court related to the sale of whole life policies on a "vanishing
premium" basis (John H. Snyder v. Nationwide Life Insurance Co.). In April 1998,
Nationwide was named as a defendant in a lawsuit filed in Ohio state court
similar to the Snyder case (David and Joan Mishler v. Nationwide Life Insurance
Co.). In August 1998, Nationwide Mutual Insurance Company and Nationwide and the
plaintiffs executed a stipulation of settlement and submitted it to the New York
state court for approval. On August 20, 1998, the court in the Snyder case
signed an order preliminarily approving a class for settlement purposes (which
would include the Mishler case) and scheduled a fairness hearing for December
17, 1998. At that hearing, the court reviewed the fairness and reasonableness of
the proposed settlement and issued a final order and judgment. The approved
settlement provides for dismissal of both the Snyder and Mishler cases, bars
class members from pursuing litigation against Nationwide Mutual Insurance
Company and its affiliates, including Nationwide and its subsidiaries, relating
to the allegations in the Snyder case, and provides class members with a
potential value of approximately $100 million in policy adjustments, discounted
premiums and discounted products.

In November 1997, two plaintiffs, one who was the owner of a variable life
insurance policy and the other who was the owner of a variable annuity contract,
commenced a lawsuit in a federal court in Texas against Nationwide and the
American Century group of defendants (Robert Young and David D. Distad v.
Nationwide Life Insurance Company et al.). In 
    

                                       25

                                   27 of 161
<PAGE>   28

   
this lawsuit, plaintiffs seek to represent a class of variable life insurance
policy 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. On December 2, 1998,
the district court issued an order denying plaintiffs' motion for class
certification. On December 10, 1998, the district court stayed the lawsuit
pending plaintiffs' petition to the federal appeals court for interlocutory
review of the order denying class certification. On December 14, 1998,
plaintiffs filed their petition for interlocutory review, on which the federal
appeals court has not yet ruled. Nationwide intends to defend the case
vigorously.

On October 29, 1998, Nationwide and certain of its subsidiaries were 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). The
plaintiff in such lawsuit seeks to represent a national class of Nationwide's
customers and seeks unspecified compensatory and punitive damages. Nationwide
currently is evaluating this lawsuit, which has not been certified as a class.
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, NISC, is not a party to any litigation of any material
nature.
    

ADVERTISING

A "yield" and "effective yield" may be advertised for the NSAT- Money Market
Fund and the Short-Term Investments Trust - Treasury Portfolio. "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 fund's units. Yield is an annualized
figure, which means that it is assumed that funds generate 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
performance of other variable annuity sub-accounts, underlying mutual fund
options with similar or different objectives, or the investment industry as a
whole. Other investments to which the sub-accounts may be compared include, but
are not limited to:

   -  precious metals;
   -  real estate;
   -  stocks and bonds;
   -  closed-end funds;
   -  bank money market deposit accounts and passbook savings;
   -  CDs; and
   -  the Consumer Price Index.

Market Indexes

The sub-accounts will be compared to certain market indexes, such as:

Tracking & Rating Services; Publications

Nationwide's rankings and ratings are sometimes published by other services,
such as:

   -  Lipper Analytical Services, Inc.;
   -  CDA/Wiesenberger;
   -  Morningstar;
   -  Donoghue's;
   -  magazines such as:

   -  Barron's;
   -  Investor's Daily;
   -  Standard & Poor's Outlook; and
   -  Variable Annuity Research & Data Service (The VARDS Report).

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,"
calculated in a manner prescribed by the SEC, and nonstandardized "total
return." Average annual total 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 all charges
made to the contracts, except for premium taxes, which may be imposed by certain
states.

Nonstandardized "total return," calculated similar to standardized "average
annual total return," shows the percentage rate of return of a hypothetical
initial investment of $10,000 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 

                                       27

underlying mutual funds would have achieved (reduced by the same charges except
the CDSC) had they been available in the variable account for one of the
periods. The CDSC is not reflected because the contracts are designed for long
term investment. The CDSC, if reflected, would decrease the level of
performance. An initial investment of $10,000 is assumed because that amount is
closer to the size of a typical contract than $1,000, which is used in
calculating the standardized average annual total return.

APPENDIX A: OBJECTIVES FOR UNDERLYING MUTUAL FUNDS

A summary of the investment objective for each underlying mutual fund is listed
below.

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

AMERICAN CENTURY:  INCOME & GROWTH - INVESTOR CLASS

The investment objective of the Fund is to seek dividend growth, current income
and capital appreciation by investing in common stocks. The Fund may buy
securities convertible into common stock, such as convertible bonds, convertible
preferred stocks or warrants. The Fund may also, for liquidity purposes, invest
in high-quality money market instruments with remaining maturities of one year
or less. The Fund may also enter into repurchase agreements, collateralized by
U.S. government securities, with banks or broker-dealers deemed to present
minimal credit risk. American Century Investment Management, Inc. serves as the
Fund's investment adviser.

   
AMERICAN CENTURY - INTERNATIONAL DISCOVERY FUND - INVESTOR CLASS (FORMERLY
"AMERICAN CENTURY - TWENTIETH CENTURY INTERNATIONAL DISCOVERY FUND - INVESTOR
CLASS")
    

The investment objective of the Fund is capital growth by investing primarily in
an internationally diversified portfolio of equity securities of issuers that
meet certain fundamental and technical standards of selection (relating
primarily to acceleration of earnings and revenues). The Fund will invest its
assets primarily in equity securities of small foreign issuers (those issuers
having, at the time of investment, a market capitalization of less than U.S. $1
billion or a public float of less than U.S. $500 million). The "public float" of
an issuer is defined as the aggregate market value of the issuer's outstanding
securities held by non-affiliates of the issuer. The Fund may invest up to 50%
of its assets in securities of issuers in emerging market countries. DUE TO THE
SIGNIFICANT RISKS ASSOCIATED WITH THE FUND'S INVESTMENT STRATEGY, AN INVESTMENT
IN THE FUND MAY NOT BE APPROPRIATE FOR ALL INVESTORS. American Century
Investment Management, Inc. serves as the Fund's investment adviser.

   
AMERICAN CENTURY: ULTRA (FORMERLY "AMERICAN CENTURY - TWENTIETH CENTURY ULTRA")
    

The investment objective of the Fund is capital growth by investing primarily in
common stocks that are considered by management to have better-than-average
prospects for appreciation. It is management's intention that the portfolio will
generally consist of common stocks of medium-sized and smaller companies.
American Century Investment Services, Inc. serves as the Fund's investment
adviser.

DREYFUS APPRECIATION FUND, INC.

The primary investment objective of the Fund is to provide long-term capital
growth consistent with the preservation of capital. Current income is a
secondary investment objective. The Fund seeks to meet its objectives by
investing primarily in the common stocks of domestic and foreign issuers. The
Dreyfus Corporation serves as the Fund's investment adviser.

DREYFUS PREMIER MIDCAP STOCK FUND - CLASS A

The investment objective of the Fund is to seek total investment returns
(including capital appreciation and income) which consistently outperform the
Standard & Poor's 400 MidCap Index. The Fund attempts to maintain a diversified
holding in common stocks of medium capitalization companies (firms with a market
value between $200 million and $5 billion). The Dreyfus Corporation serves as
the Fund's investment adviser.

THE DREYFUS THIRD CENTURY FUND, INC.

The Fund's primary goal is to provide capital growth through equity investment
in companies that, in the opinion of the Fund's management, not only to 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

                                       32

                                   34 of 161
<PAGE>   33

life of America. Current income is secondary to the primary goal. The Dreyfus
Corporation serves as the Fund's investment adviser.

FEDERATED BOND FUND - CLASS F

The investment objective of the Fund is to provide as high a level of current
income as is consistent with the preservation of capital. The Fund invests
primarily in a professionally managed, diversified portfolio of bonds. Under
normal circumstances, at least 65% of the Fund's net assets will be invested in
investment grade securities, including repurchase agreements collateralized by
investment grade securities. The Fund may invest in corporate debt obligations,
U.S. Government obligations, municipal securities, asset-backed securities,
adjustable rate mortgage securities, collateralized mortgage obligations, and
other securities which are deemed to be consistent with the Fund's investment
objectives. Federated Advisers serves as the Fund's investment adviser.

FEDERATED U.S. GOVERNMENT SECURITIES FUND: 2-5 YEARS - INSTITUTIONAL SHARES

The investment objective of the Fund is current income. The Fund pursues this
investment objective by investing in U.S. government securities with remaining
maturities of five years or less. Federated Management serves as the Fund's
investment adviser.

FIDELITY ADVISOR GROWTH OPPORTUNITIES FUND - CLASS A

The investment objective of the Fund is to pursue capital growth that exceeds
market performance through investments in growth, cyclical, and value stocks.
Fidelity Management & Research Company serves as the Fund's investment adviser.

FIDELITY ADVISOR HIGH YIELD FUND - CLASS T

The Fidelity Advisor High Yield Fund is a bond fund designed to meet the needs
of the long-term investor, seeking above-average monthly income and potential
capital growth by investing in lower-rated, high-yielding, fixed income
securities. Fidelity Management & Research Company serves as the Fund's
investment adviser.

FIDELITY EQUITY-INCOME FUND

The investment objective of the Fund is to obtain reasonable income from a
portfolio consisting primarily of income-producing equity securities. The Fund
seeks a yield which exceeds the composite yield on the securities comprising the
Standard & Poor's Composite Index of 500 Stocks. In pursuing this objective, the
Fund will also consider the potential for capital appreciation. Fidelity
Management & Research Company serves as the Fund's investment adviser.

FIDELITY OTC PORTFOLIO

The investment objective of the Fund is to seek capital appreciation by
investing primarily in securities traded on the over-the counter (OTC)
securities market. Securities traded on the OTC include, among others,
industrial corporations, financial services institutions, public utilities, and
transportation companies, common and preferred stocks, securities convertible
into common stock, warrants and similar rights, and debt securities, and
obligations of the federal government. The fund does not place any weight on
dividend and interest income unless it believes this income will have a
favorable influence on the market value of a security. Fidelity Management &
Research Company serves as the Fund's investment adviser.

FIDELITY PURITAN FUND

The investment objective of the Fund seeks to obtain as much income as possible,
consistent with the preservation and conservation of capital, by investing in a
broadly diversified portfolio of securities, including common stocks, preferred
stocks, and bonds. While emphasis on income is an important objective, this does
not preclude growth in capital since some securities offering a better than
average yield may also possess some growth possibilities. Fidelity Management &
Research Company serves as the Fund's investment adviser.

INVESCO DYNAMICS FUND

The investment objective of the Fund is to seek appreciation of capital through
aggressive investment policies. The Fund invests primarily in common stocks of
U.S. companies traded on national securities exchanges and over-the-counter. The
Fund also has the flexibility to invest in preferred stocks and convertible or
straight issues of debentures, as well as foreign securities. INVESCO Funds
Group, Inc. serves as the Fund's investment adviser.

INVESCO TOTAL RETURN FUND

The investment objective of the Fund is to seek to achieve a high total return
on investment through capital appreciation and current income by investing in a
combination of equity securities (consisting of common stocks and, to a lesser
degree, securities convertible into common stock) and fixed income securities.
The equity securities purchased by the Fund generally will be issued by
companies which are listed on a national securities exchange and which usually
pay regular dividends. This Fund seeks reasonably consistent total returns over
a variety of market cycles. INVESCO Funds Group, Inc. serves as the Fund's
investment adviser. INVESCO Capital Management, Inc. serves as the Fund's
sub-adviser.

LIFEDESIGNS SERIES

LifeDesigns Series consists of five separate nondiversified funds, each of which
is a separately managed nondiversified portfolio with its own investment
objective and policies. The objective of each of the Portfolios which is
fundamental, is to maximize total investment return (i.e. capital growth and
income) subject to investment restrictions and asset allocation policies. The
Portfolios will maximize total investment return as is specifically detailed in
the following objectives which are non-fundamental and can be changed without
approval of a Portfolio's shareholders.

     THE AGGRESSIVE PORTFOLIO

     The investment objective of this Fund is to provide growth of capital by
     investing in underlying funds which invest primarily in equity securities
     ("Equity Funds"). This Fund is generally appropriate for investors seeking
     higher returns over an investment time horizon of at least 15 years and
     having a higher tolerance for market fluctuations. Nationwide Advisory
     Services, Inc. ("NAS") serves as the Fund's investment adviser.

     THE CONSERVATIVE PORTFOLIO

     The investment objective of this Fund is to provide primarily income and,
     secondarily, long term growth of capital. This Fund will seek to meet its
     objectives by primarily investing in a combination of the Nationwide
     Contract (a fixed interest contract) and fixed income securities ("Bond
     Funds"), with a similar investment in Equity Funds. This Fund is generally
     appropriate for investors seeking low fluctuations in principal over an
     investment time horizon of less than 5 years, as well more conservative
     investors with an investment time horizon of between 5 and 10 years. NAS
     serves as the Fund's investment adviser.

     THE MODERATE PORTFOLIO

     The investment objective of this Fund is to provide growth of capital and
     income by investing primarily in Equity Funds, but will also invest a
     significant percentage of its assets in the Nationwide Contract and in Bond
     Funds. This Fund is generally appropriate for moderate investors seeking
     moderate returns over an investment time horizon of between 10 and 15
     years; conservative investors with an investment time horizon of at least
     15 years or more; and more aggressive investors with an investment time
     horizon of 5 to 10 years. NAS serves as the Fund's investment adviser.

     THE MODERATELY AGGRESSIVE PORTFOLIO

     The investment objective of this Fund is to provide growth of capital by
     investing primarily in Equity Funds. However, the

GENERAL INFORMATION AND HISTORY

   
The variable account is a separate investment account of Nationwide Life
Insurance Company ("Nationwide"). Nationwide is a member of the Nationwide
Insurance Enterprise and 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.
    

SERVICES

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

All assets of the variable account are held in custody for safekeeping by
Nationwide. The assets of each sub-account will be kept physically segregated
and held separate and apart from assets of other sub-accounts and from assets of
any other firm, person, or corporation. Nationwide will maintain a record of all
and redemption for shares of the underlying mutual fund held in each
sub-account.

Nationwide, or affiliates of Nationwide, may have entered into agreements with
either the investment adviser or distributor for several of 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 and schedules 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.

   
For those plans which provide this contract and Nationwide's Group Fixed Fund
Retirement Contracts, the contract owner, or the participant if the plan so
provides, may exchange accumulation units between any sub-account of the
variable account and the deposit fund of the Group Fixed Fund Retirement
Contract. Exchanges from the deposit fund to any sub-account of the variable
account will be subject to the limitations of the Group Fixed Fund Retirement
Contract. Exchanges will be effective when received in good order at
Nationwide's home office.
    

UNDERWRITERS

   
The contracts, which are offered continuously, are distributed by Nationwide
Investment Services Corporation ("NISC"), Two Nationwide Plaza, Columbus, Ohio
43215. NISC is 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 NISC.
    

CALCULATION OF PERFORMANCE

   
Any current yield quotations of the Nationwide Money Market Fund and the
Short-Term Investments Trust Treasury Portfolio sub-accounts, subject to Rule
482 of the Securities Act of 1933, shall 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 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. As of December 31, 1998, the
Nationwide Money Market Fund and the Short-Term Investments Trust Treasury
Portfolio Sub-Accounts seven-day current yield were 3.74% and 2.47%
respectively. The Nationwide Money Market Fund and the Short-Term Investments
Trust Treasury Portfolio sub-accounts' seven-day effective yield is computed
similarly but includes the effect of assumed compounding on an annualized basis
of the current yield quotations of the sub-accounts, and for the period ending
December 31, 1998 were 3.80% and 2.50% respectively.
    

The yield and effective yield will fluctuate daily. Actual yields will depend on
factors such as the type of instruments in the sub-accounts' portfolios,
portfolio quality and average maturity, changes in interest rates, and the
sub-accounts' expenses. Although the sub-account determines its yield on the
basis of a seven calendar day period, it may use a different time period on
occasion. 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 Nationwide Money Market Fund and the Short Term Investment
Trust Treasury Portfolio sub-account 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.

   
Nationwide may, from time to time, advertise several types of historical
performance of the sub-accounts. Nationwide may advertise for the sub-accounts
standardized "average annual total return," calculated in a 
    

                                       2

                                   79 of 161

<PAGE>   78
manner prescribed by the SEC, and nonstandardized "total return". "Average
annual total return" will show 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 option has been
available in the variable account if the underlying mutual fund option has not
been available in the variable account for any of the prescribed periods. THIS
CALCULATION REFLECTS THE DEDUCTION OF ALL APPLICABLE CHARGES MADE TO THE
CONTRACTS EXCEPT FOR PREMIUM TAXES, WHICH MAY BE IMPOSED BY CERTAIN STATES.

Nonstandardized "total return," calculated similar to standardized "average
annual total return," illustrates the percentage rate of return of a
hypothetical initial investment of $10,000 for the most recent one, five and ten
year periods, or for a period covering the time the underlying mutual fund
option has been in existence. For those underlying mutual fund options which
have not been held as sub-accounts for one of the prescribed periods, the
nonstandardized total return illustrations will show the investment performance
such underlying mutual fund options would have achieved (reduced by the same
charges except the Participant Account Maintenance Charge and CDSC) had such
underlying mutual fund options been available in the variable account for the
periods quoted. THE CDSC IS NOT REFLECTED BECAUSE THE CONTRACTS ARE DESIGNED FOR
LONG TERM INVESTMENT. THE CDSC, IF REFLECTED, WOULD DECREASE THE LEVEL OF
PERFORMANCE SHOWN. AN INITIAL INVESTMENT OF $10,000 IS ASSUMED BECAUSE THAT
AMOUNT MORE CLOSELY APPROXIMATES THE SIZE OF A TYPICAL CONTRACT THAN DOES THE
$1,000 ASSUMPTION USED IN CALCULATING THE STANDARDIZED AVERAGE ANNUAL TOTAL
RETURN QUOTATIONS.

                          Independent Auditors' Report

The Board of Directors of Nationwide Life Insurance Company and Contract Owners
   of NACo Variable Account:

      We have audited the accompanying statement of assets, liabilities and
contract owners' equity of NACo Variable Account as of December 31, 1998, and
the related statements of operations and changes in contract owners' equity for
each of the years in the two year period then ended. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

      We conducted our audits 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. Our procedures include
confirmation of securities owned as of December 31, 1998, by correspondence with
the transfer agents of the underlying mutual funds. 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 financial statements referred to above present fairly,
in all material respects, the financial position of NACo Variable Account as of
December 31, 1998, and the results of its operations and its changes in contract
owners' equity for each of the years in the two year period then ended in
conformity with generally accepted accounting principles.

                                                                        KPMG LLP

                          NOTES TO FINANCIAL STATEMENTS
                           December 31, 1998 and 1997


(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (a) Organization and Nature of Operations

         NACo Variable Account (NACoVA) was established pursuant to a resolution
         of the Board of Directors of Nationwide Life Insurance Company (the
         Company) on September 7, 1988, and has been registered as a unit
         investment trust under the Investment Company Act of 1940. The NACoVA
         was introduced for exclusive use by Member Counties for deferred
         compensation Plans adopted under the National Association of Counties
         (NACo) Program. 

         The Company offers group flexible fund retirement contracts through the
         NACoVA. The primary distribution for the contracts is through an
         affiliated sales organization.

     (b) The Contracts

         The Group Flexible Retirement Contracts (the Contract) are offered for
         purchase in connection with deferred compensation Plans adopted by
         Member Counties under the NACo Program. Participants in the contracts

         All of the above funds were being utilized as of December 31, 1998.

         The contract owners' equity is affected by the investment results of
         each fund, equity transactions by contract owners and certain expenses
         (see note 2). The accompanying financial statements include only
         contract owners' purchase payments pertaining to the variable portions
         of their contracts and exclude any purchase payments for fixed dollar
         benefits, the latter being included in the accounts of the Company.
<PAGE>   21
     (c) Security Valuation, Transactions and Related Investment Income

         The market value of the underlying mutual funds is based on the closing
         net asset value per share at December 31, 1998. The cost of investments
         sold is determined on the specific identification basis. Investment
         transactions are accounted for on the trade date (date the order to buy
         or sell is executed) and dividend income is recorded on the ex-dividend
         date.

     (d) Federal Income Taxes

         Operations of the NACoVA form a part of, and are taxed with, operations
         of the Company, which is taxed as a life insurance company under the
         Internal Revenue Code. The assets in this account are held pursuant to
         contracts with entities which are exempt from federal income tax.
         Because of this exemption, no taxes need be provided for investment
         income or realized and unrealized capital gains. Annuity payouts and
         withdrawal payments are taxable as wages when received by the
         participants.

     (e) Use of Estimates in the Preparation of Financial Statements

         The preparation of financial statements in conformity with generally
         accepted accounting principles may require management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities, if
         any, at the date of the financial statements and the reported amounts
         of revenues and expenses during the reporting period. Actual results
         could differ from those estimates.

(2)  EXPENSES

     No deduction for a sales charge is made from the purchase payments for
     these contracts. However, if an owner terminates the contract and directs
     the Company to withdraw all or part of the contract value held in the
     Account for less than sixteen (16) years, the Company will, with certain
     exceptions, assess a contingent deferred sales charge by deducting an
     amount from each participant's account. This charge will be equal to not
     more than 4% in the first year, declining to 1% in the fifteenth year, of
     the lesser of all purchase payments made on behalf of a participant prior
     to the date of withdrawal, or the amount withdrawn. No sales charges are
     deducted on redemptions used to purchase units in the fixed investment
     options of the Company. Sales charges may be reduced or eliminated upon
     negotiated conversion of the contracts to other investment programs offered
     by the Company or its affiliates. 

     Prior to May 1, 1998 the following charges were deducted by the Company: a
     mortality risk charge, an expense risk charge and an administration charge
     which are assessed through the daily unit value calculation. The morality
     risk charge and the expense risk charge are equal to an annual rate of
     0.10% and 0.40% respectively; and the administration charge prior to May 1,
     1996 was 0.45%. Beginning May 1, 1996, the administration charge is based
     upon the aggregate balance of assets held under the Contract by each Member
     County, as follows:

                   I                     Up to $10                   .45%
                  II                  Over $10 to $25                .40%
                  III                 Over $25 to $50                .30%
                  IV                 Over $50 to $150                .20%
                   V                     Over $150                   .15%
</TABLE>

     The administration charge is determined using the December 31 asset balance
     and is effective at the next expense tier on the following May 1. 

     Beginning May 1, 1998 under the terms of the Contracts, the Company assumes
     various risks and incurs administrative expenses associated with the
     issuance of the Contracts. For the Company's contractual promise to accept
     these risks and expenses, the Contracts provide for the deduction of a
     Variable Account Fee, which is calculated as a percentage of assets and is
     deducted on each valuation date from amounts held in the Account. On an
     annual basis, the maximum Variable Account Fee is 0.95% of the average
     account value.
<PAGE>   22
     As with all other charges, this fee is subject to negotiation and may vary
     from one contract to another reflecting the unique characteristics of
     different contracts when considered as a whole. In negotiating the amount
     of the fee, the Company may consider factors which may reduce expenses
     incurred by the Company. These factors might include, but are not limited
     to: (1) the size of the contract; (2) the number of eligible employees; (3)
     the number of contract participants; (4) demographics of contract
     participants; (5) general economic conditions; (6) the varying costs
     associated with the inclusion of underlying mutual fund options; (7) the
     type of contract issued (for example, whether the contract is issued as an
     allocated contract or unallocated contract); (8) costs associated with
     distribution of the contract; and (9) any other factors which the Company
     deems relevant. (See summary of variable account fees at Note 5)

     Contract owners may negotiate an exchange privilege with the Company. The
     exchange privilege provides for transfers of units among the various
     investment options for each participant's account. The number of transfers
     allowed, and any administrative charges associated therewith, are subject
     to negotiation between the contract owner and the Company.

(3)  RELATED PARTY TRANSACTIONS

     The Company performs various services on behalf of the Mutual Fund
     Companies in which the Account invests and may receive fees for the
     services performed. These services include, among other things, shareholder
     communications, preparation, postage, fund transfer agency and various
     other record keeping and customer service functions. These fees are paid to
     an affiliate of the Company.

                          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.


                                                                        KPMG LLP

               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.

         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

(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

(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.

              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.

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

              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.

              Notes to Consolidated Financial Statements, Continued



         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:

         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
         variable universal life insurance and corporate-owned life insurance
         products, that provide a death benefit and may also allow the customer
         to build cash value on a tax-deferred basis.

         In addition to the product segments, the Company reports corporate
         revenue and expenses, investments and related investment income
         supporting capital not specifically allocated to its product segments,
         revenues and expenses of its investment advisor subsidiary (other than
         the portion allocated to the Variable Annuities and Life Insurance
         segments), revenues and expenses related to group annuity contracts
         sold to Nationwide Insurance Enterprise employee and agent benefit
         plans and all realized gains and losses on investments in a Corporate
         and Other segment.

         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

   
         The number of contract owners as of January 31, 1999 was 3,448.
    

Item 28.  Indemnification

   
         Provision is made in Nationwide's Amended 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.
    


Item 29.      PRINCIPAL UNDERWRITER

              (a)   Nationwide Investment Services Corporation ("NISC") serves
                    as principal underwriter and general distributor for the
                    Nationwide DC Variable Account and the NACo Variable
                    Account.

         (a)      File a post-effective amendment to this registration statement
                  as frequently as is necessary to ensure that the audited
                  financial statements in the registration statement are never

         (b)      Include either (1) as part of any application to purchase a
                  contract offered by the prospectus, a space that an applicant
                  can check to request a Statement of Additional Information, or
                  (2) a post card or similar written communication affixed to or
                  included in the prospectus that the applicant can remove to
                  send for a Statement of Additional Information; and

         (c)      Deliver any Statement of Additional Information and any
                  financial statements required to be made available under this
                  Form promptly upon written or oral request.

         (d)      Represent that any contract offered by the prospectus and
                  which is issued pursuant to Section 403(b) of the Code, is
                  issued by the Registrant in reliance upon, and in compliance
                  with, the Securities and Exchange Commission's no-action

         The Depositor hereby represents:

   
          (a)     That the fees and charges deducted under the contract in the
                  aggregate are reasonable in relation to the services rendered,
                  the expenses expected to be incurred, and the risks assumed by
                  Nationwide.
