4.   THE "APPENDIX - PARTICIPATING UNDERLYING MUTUAL FUNDS" AT PAGES 37 THROUGH
     40 OF THE PROSPECTUS IS AMENDED BY ADDING THE FOLLOWING FUND OBJECTIVES:

NPMP 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.

NPMP - 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.

NPMP - 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 Bond Funds, with a smaller 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 as
more conservative investors with an investment time horizon of between 5 and 10
years. NAS serves as the Fund's investment Adviser.

NPMP - 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 fixed income
securities ("Bond Funds"). This Fund is 

                                    4 of 134
<PAGE>   5


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.

NPMP - THE MODERATELY AGGRESSIVE PORTFOLIO

The investment objective of this Fund is to provide growth of capital by
investing primarily in Equity Funds. However, the Fund attempts to reduce its
volatility by also investing in the Nationwide Contract and Proprietary Funds
which also invest primarily in Bond Funds. This Fund is generally appropriate
for moderate investors seeking high returns over an investment time horizon of
15 years or for more aggressive investors with an investment time horizon of 10
to 15 years. NAS serves as the Fund's investment Adviser.

NPMP - THE MODERATELY 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 generally investing half of its assets in Equity Funds with the
remainder in the Nationwide Contract and Bond Funds. This Fund is generally
appropriate for moderate investors seeking lower fluctuations in principal
combined with some of the upside potential of equity investments over an
investment time horizon of between 5 and 10 years. This Fund is also generally
appropriate for conservative investors with an investment time horizon of
between 10 and 15 years and more aggressive investors with an investment time
horizon of less than 5 years. NAS serves as the Fund's investment Adviser.


NSAT - NATIONWIDE SMALL COMPANY FUND

The investment objective of the Fund is long-term growth of capital by investing
primarily in equity securities of domestic and foreign companies with market
capitalizations of less than $1 billion at the time of purchase. The
subadvisers, Dreyfus Corporation, Neuberger & Berman, L.P., Pictet International
Management Limited with Van Eck Associates Corporation, Strong Capital
Management, Inc. and Warburg Pincus Asset Management, Inc., were chosen because
they utilize a number of different investment styles when investing in small
company stocks. By utilizing different investment styles, the Fund's advisor
Nationwide Advisory Services, Inc., hopes to increase prospects for investment
return and to reduce market risk and volatility.

                     ISSUED BY THE NACO VARIABLE ACCOUNT OF
                        NATIONWIDE LIFE INSURANCE COMPANY

     The Group Flexible Fund Retirement Contracts (the "Contract" or
"Contracts") described in this prospectus are designed for use in connection
with deferred compensation Plans adopted by Member Counties under the NACo
Program. Such Plans generally qualify for favorable tax treatment under Section
457 of the Internal Revenue Code ("Code"). The assets of such Plans are part of
the general assets of the Member County, provided however that the Member County
must hold all such Plan assets for the exclusive benefit of the Plan's
Participants and beneficiaries. Rights and privileges under the Contracts may be
exercised by the Member County to the extent such rights are not specifically
reserved in the Plan for Participants as a group or as individuals. The member
County may not take any action inconsistent with the rights of the Plan's
Participants. The Participants have a contractual claim against the Member
County for the benefits promised by such Plans. The Participants are generally
not subject to tax until Distributions are received from the Plan. Purchase
Payments made at any time by or on behalf of any Participant must be at least
$20 per month.

     Purchase Payments are allocated to the NACo Variable Account. NACo Variable
Account is a unit investment trust with 28 Sub-Accounts of unit values, each
reflecting investment results of a different management investment company.
Amounts equivalent to the obligations of Nationwide Life Insurance Company ("the
Company") under each Sub-Account will be invested in Underlying Mutual Funds
(see Appendix of Participating Underlying Mutual Funds).

about the Group Flexible Fund Retirement Contracts issued by NACo Variable
Account before investing. You should read it and keep it for future reference. A

</TABLE>


     This Example should not be considered a representation of past or future
     expenses. Actual expenses may be greater or lesser than those shown.

     The purpose of the preceding tables is to assist the Participant in
     understanding the various costs and expenses that a Participant will bear
     directly or indirectly when investing in the Contract. The table reflects
     expenses of the NACo Variable Account as well as the Underlying Mutual Fund
     investment options. For a more detailed explanation of these expenses, see
     "NACo Variable Account Charges, Purchase Payments, and Other Deductions."
     For more and complete information regarding expenses paid out of the assets
     of a particular Underlying Mutual Fund, see the Underlying Mutual Fund's
     prospectus. In addition to the expenses shown above, deductions for premium
     taxes may also be applicable, depending upon the jurisdiction in which the
     Contract is sold (see "Premium Taxes").

                                    SYNOPSIS


     The Contracts described in this prospectus are designed for use in
connection with deferred compensation plans adopted by Member Counties under the
NACo Program. Such Plans qualify for favorable tax treatment under Section 457
of the Code. The Participants generally are not subject to federal income tax on
amounts deferred under such plans until Distributions are received from the
Plan. Purchase Payments made at any time by or on behalf of any Participant must
be at least $20 per month.

     Purchase Payments under the Contracts are placed in the NACo Variable
Account. The NACo Variable Account is a unit investment trust with 28
Sub-Accounts of unit values, each reflecting investment results of a different
Underlying Mutual Fund. Amounts equivalent to the obligations of the Company
under each Sub-Account will be invested in the specified Underlying Mutual Fund
(see "Appendix of Participating Funds").

     The Company does not deduct a sales charge from Purchase Payments made for
these Contracts. However, in the event of the termination of this Contract and
directions from the Owner to the Company to withdraw all or part of the account
value of the Contract, the Company will, with certain exceptions, deduct from
the Contract Value, on a per Participant basis, a Contingent Deferred Sales
Charge ("CDSC") equal to not more than 4% of the lesser of the total of all
Purchase Payments made prior to the date of the request for withdrawal, or the
amount withdrawn. Absent Contract termination by the Owner, the CDSC provision
will not apply and therefore any full or partial withdrawals made on behalf of a
Participant will not be subject to any CDSC. The CDSC, when applicable, is
imposed to permit the Company to recover sales expenses which have been advanced
by the Company (see "Contingent Deferred Sales Charge").

     Any applicable premium taxes can be deducted and will be charged against
the Contracts. If any such premium taxes are payable at the time Purchase
Payments are made, the premium tax deduction will be made from the Contract
prior to allocation to any Underlying Mutual Fund option (see "Premium Taxes").

     A daily deduction is made from the NACo Variable Account in an amount
equivalent to an annual rate of up to 0.95% of average account value of the NACo
Variable Account for the Company's contractual promises to accept the mortality
and expense risks and for administration of the NACo Variable Account (see
"Mortality and Expense Risk and Administration Charges"). In addition, the
investment companies whose shares are purchased by the NACo Variable Account
make certain deductions from their assets.

     The Contracts provide that the deductions made from Purchase Payments,
Participants' Accounts, the Contingent Deferred Sales Charges, and Actuarial
Risk Fees may be decreased by the Company after the first Contract Year upon
notice to the Owner (see "Modification of the Contract").

                        NATIONWIDE LIFE INSURANCE COMPANY

     Nationwide Life Insurance Company (the "Company") is a stock life insurance
company organized under the laws of the State of Ohio in March, 1929. The
Company is a member of the "Nationwide Insurance Enterprise", with its Home
Office at One Nationwide Plaza, Columbus, Ohio 43215. The Company offers a
complete line of life insurance, including annuities and accident and health
insurance. It is admitted to do business in all states, the District of
Columbia, the Virgin Islands, and Puerto Rico.

                            THE NACO VARIABLE ACCOUNT

     NACo Variable Account was established by the Company on September 7, 1988,
pursuant to the provisions of Ohio law. NACo Variable Account has been
registered with the Securities and Exchange Commission as a unit investment
trust pursuant to the provisions of the Investment Company Act of 1940. Such
registration does not involve supervision of the management of the NACo Variable
Account or the Company by the Securities and Exchange Commission.

     The net Purchase Payments applied to the NACo Variable Account are invested
in shares of the Underlying Mutual Funds available under the terms of the
Contract. The NACo Variable Account is divided into 28 Sub-Accounts of
Accumulation Units, each of which represents a separate Underlying Mutual Fund
(see "Appendix Participating Funds" for a description of the investment
objective of each Underlying Mutual Fund).

     Each Sub-Account in the NACo Variable Account is administered and accounted
for as a part of the separate account, but the income, capital gains or losses
of each Sub-Account are credited to or charged against the assets held for that
Sub-Account in accordance with the terms of each Contract, without regard to
other income, capital gains or losses of any other Sub-Account, or arising out
of any other business the Company may conduct. The assets within each
Sub-Account are not chargeable with liabilities arising out of the business
conducted by any other Sub-Account, nor will the NACo Variable Account as a
whole be chargeable with liabilities arising out of any other business the
Company may conduct.

VOTING RIGHTS

     The NACo Variable Account will be owner of record of all Underlying Mutual
Fund shares purchased by the respective account until such Underlying Mutual
Fund shares are sold, but all securities will be held for the benefit of the
Owners of the Contracts. In accordance with its view of present applicable law,
the Company will vote the shares of the Underlying Mutual Funds held in the NACo
Variable Account at regular and special meetings of the shareholders of the
Underlying Mutual Funds in accordance with instructions received from the
Owners. The Company or its designee will mail to each Owner at its last known
address all periodic reports and proxy material of the applicable Underlying
Mutual Fund, and a form with which to give voting instructions. Any Underlying
Mutual Fund shares as to which no timely instructions are received will be voted
by the Company in the same proportion as the instructions received from all
persons furnishing timely instructions. An Owner's voting rights may decrease
with the cancellation of Accumulation Units to make annuity payments.

                                PERIODIC REPORTS

     The Company or its designee will, semi-annually, provide to each person
covered by a Contract, a Statement of Assets, Liabilities and Contract Owners'
Equity and a Statement of Operations and Changes in Contract Owners' Equity of
the NACo Variable Account. Each Participant and Retired Participant will also be
informed, periodically, of the number of Accumulation Units credited to his or
her account as well as the total account value.

     The current prospectus of the NACo Variable Account will be made available
to Participants through the Owner. In addition, the Owner may, under the terms
of the Plan, have an obligation to furnish additional information to
Participants, such as: a notice of any changes in the Plan, or tax status of the
Plan and the financial condition of the Owner as it relates to obligations under
the Plan.

      NACO VARIABLE ACCOUNT CHARGES, PURCHASE PAYMENTS AND OTHER DEDUCTIONS

CONTINGENT DEFERRED SALES CHARGE

     No deduction for a sales charge is made from the Purchase Payments for
these Contracts. However, a Contingent Deferred Sales Charge ("CDSC"), when it
is applicable, will be used to cover expenses relating to the sale of the
Contracts, including compensation paid to sales personnel, the costs of
preparation of sales literature, and other promotional activity. The Company
attempts to recover its Distribution costs relating to the sale of the Contracts
from a Contingent Deferred Sales Charge. Any shortfall will be borne by the
Company from surplus held in its General Account, which may indirectly include
portions of the Actuarial Risk Fee, since the Company intends to generate a
profit from this fee.

     If the Owner terminates the Contract in accordance with the Section
entitled "Suspension and Termination", and directs the Company to withdraw all
or part of the Contract Value, the Company will assess a CDSC against the amount
withdrawn, by deducting an amount from each Participant's Account as indicated
below. For purposes of the CDSC, withdrawals under a Contract come first from
the Purchase Payments which have been on deposit under the Contract for the
longest time period.

     For withdrawals made through December 31, 1997, the CDSC will be the lesser
of (i) and (ii) shown below, where:

     (i)   is the lesser of 4% of the Purchase Payments made on behalf of a
           Participant prior to the date of the withdrawal, or 4% of the amount
           withdrawn; and

     (ii)  is the lesser of the applicable percentage set forth in the table
           below multipled by the Purchase Payments made on behalf of a
           Participant prior to the date of withdrawal, or the applicable
           percentage set forth below multiplied by the amount withdrawn.

     For withdrawals made after December 31, 1997, the CDSC will be the lesser
of (iii) and (iv) below, where:

     (iii) is the lesser of 2% of the Purchase Payments made on behalf of a
           Participant prior to the date of the withdrawal, or 2% of the amount
           withdrawn; and

     (iv)  is the lesser of the applicable percentage set forth in the table
           below multiplied by the Purchase Payments made on behalf of a
           Participant prior to the date of withdrawal, or the applicable
           percentage set forth below multiplied by the amount withdrawn.

     Notwithstanding the above, the Contingent Deferred Sales Charge will not
apply to any withdrawals made on or after January 1, 2001.

     Years of participation credited toward the CDSC schedule as set forth above
may only be those earned beginning with the date of a Participant's first
deferral deposited in the Contracts.


MORTALITY AND EXPENSE RISK AND ADMINISTRATION CHARGES

     The Contracts contain purchase rates applicable at and after retirement.
These purchase rates may be used to determine the Retirement Income Payments to
be made by the Owner to Participants in accordance with the terms of the Plan.
However, the Owners have contracted with the Company to provide Retirement
Income Payments.

     Under the terms of the Contracts, the Company assumes the risk that the
actuarial estimate of mortality rates among Retired Participants may prove
erroneous and amounts set aside for retirement income benefits on the basis of
such estimate may prove inadequate.

                                      16

                                   21 of 134
<PAGE>   22



     For the Company's contractual promise to accept these risks and for the
administrative costs associated with the NACo Variable Account, the Contracts
provide for the daily deduction of an Actuarial Risk Fee (see "Glossary of
Terms"). The deduction is based on the daily value of the applicable NACo
Variable Account Sub-Account, and is equivalent to a maximum of 0.95% on an
annual basis (0.10% for the mortality risk, 0.40% for the expense risk, and
0.45% for administration of the NACo Variable Account). The 0.45% administration
portion of the Actuarial Risk Fee has been set at a level to recover no more
than the actual cost associated with administering the Contracts. If this
Actuarial Risk Fee is insufficient to cover the actual cost of the mortality
risk, the expense risk, or the administrative costs, the loss will be borne by
the Company. Conversely, if the Actuarial Risk Fee proves more than sufficient,
the excess will be a profit to the Company. If total assets of a Plan under the
NACo Program exceed $10 million, as of the specified date each year, the 0.45%
Administrative portion of the Actuarial Risk Fee will be reduced on a sliding
scale corresponding to total assets of a plan under the NACo Program (see
"Summary of Contract Expenses"). This reduction reflects the lower cost per
Participant to administer larger asset pools.

PREMIUM TAXES AND OTHER EXPENSES

     The Company will charge against Purchase Payments or the Contract Value the
amount of any premium taxes levied by a state or any other governmental entity
upon annuity considerations received by the Company. Premium tax rates currently
in effect in certain states range from 0% to 3.5% per annum. This range is
subject to change. Purchase Payments may be reduced or Accumulation Units
cancelled to recover premium taxes assessed.

     There are deductions and expenses paid out of the assets of the Underlying
Mutual Funds (see "Underlying Mutual Fund Annual Expenses") that are more fully
described in the prospectus for the Underlying Mutual Funds.

EXPERIENCE CREDITS

     The Contracts described herein either are participating or nonparticipating
depending on the state of issue. A participating Contract provides the right to
participate in the distribution of surplus of the Company. In the event that
Actuarial Risk Fees collected under this Contract accrue to the Company in
excess of an amount deemed necessary at the sole discretion of the Company's
Board of Directors, such excess may be allocated to the Contract by purchasing
additional Accumulation Units and crediting such additional units to the
Participant Accounts. There have not been any such experience credits on
participating Contracts to date. The Company cannot offer any assurance that
there will be experience credits under its participating contracts in the
future. With respect to nonparticipating contracts, there is no right to
participate.

EXPENSES OF THE NACO VARIABLE ACCOUNT

     The NACo Variable Account's total expenses for the fiscal year ended
December 31, 1996 were 0.88% of the average net assets on an annualized basis.
Deductions from and expenses paid out of the assets of the Underlying Mutual
Funds are described in the prospectus of each Underlying Mutual Fund.


                          DESCRIPTION OF THE CONTRACTS

PURPOSE OF THE CONTRACTS

     The Contracts described in this prospectus are Group Flexible Fund
Retirement Contracts designed to fund Plans adopted by Member Counties under the
NACo Program established under Section 457 of the Code. A single group Contract
is issued to the Owner, covering all present and future participating employees.
The Company will issue a certificate to the Owner for delivery to each Retired
Participant or other person for whom an Optional Retirement Income Form is
purchased, setting forth in substance the benefits to which such person is
entitled. In addition, if any applicable law requires, the Company will issue a
descriptive certificate to the Owner for delivery to any such person required by
law to receive such certificate, setting forth in substance the benefits to
which such person is entitled. For purposes of determining benefits payable
under the Plan, an individual accumulation account is established for each
Participant. The frequency of Purchase Payments is normally monthly, but may be
adjusted to fit the payroll practices of the Owner. Purchase Payments made at
any time by or on behalf of any Participant must be at least $20 per month.

     The basic objectives of the Contracts are to provide each Participant with
an initial Retirement Income Payment, which will tend to reflect the changes
which have occurred in the cost of living during pre-retirement years (without
the necessity of increased Purchase Payments to keep pace with any increase in
the cost of living which might occur during those years), and to provide
subsequent Retirement Income Payments which will tend to vary with the cost of

                                      17

                                   22 of 134
<PAGE>   23



living changes during his or her retired lifetime. The Company seeks to
accomplish these objectives by applying purchase rates contained in the Contract
to the amounts accumulated through investment in Underlying Mutual Funds.
Notwithstanding the foregoing, there is no assurance that these objectives will
be attained. 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. There has, however, been no exact correlation, and for some periods,
the prices of securities have declined while the cost of living was rising.

MODIFICATION OF THE CONTRACT

     Contract provisions with respect to the deductions made from Purchase
Payments, Participant Accounts, the Contingent Deferred Sales Charges, if
applicable, and Actuarial Risk Fees may be decreased upon notice to the Owner.

     Other than as set forth above, the Company reserves the right to change all
other provisions of the Contract by giving notice to the Owner not less than 90
days before the effective date of the change.

CONTRACT RIGHTS AND PRIVILEGES AND ASSIGNMENTS

     The Contract belongs to the Owner provided, however, that under Code
Section 457 Plans, the Owner must hold the Contract for the exclusive benefit of
the Plan's participants and beneficiaries. All contractual rights and privileges
may be exercised by the Owner, subject to any rights specifically reserved in
the Plan for Participants as a group or as individuals. With respect to 457
Plans, the Owner may not take any action inconsistent with the rights of such
457 Plan's participants. The Contract may not be assigned.

EXCHANGE PRIVILEGE

     The Company will permit the Owner, or the Participant if the Plan so
provides, to 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.
For those Contracts where the Owner has elected an exchange privilege, there
will be no charge for exchanges among the Sub-Accounts.

     The Company will also permit the Participant to utilize the Telephone
Exchange Privilege, for exchanging amounts among Sub-Accounts, if forms are
executed by the Contract Owner and Participant agreeing with certain
restrictions applicable to such privilege.

     Telephone exchange requests must be received by the Company by the close of
the New York Stock Exchange in order to receive that day's closing Sub-Accounts
price. A telephone exchange request may not be revoked once instructions have
been recorded and accepted. If the Participant is unable to execute an exchange
request by telephone (for example, during times of unusual market activity), the
Participant might consider placing the exchange order by mail. The Company will
employ reasonable procedures to confirm that instruction communicated by
telephone are genuine. Such procedures may include any or all of the following,
or such other procedures as the Company may, from time to time, deem reasonable:
requesting identifying information, such as name, contract number, Social
Security Number, and/or personal identification number; tape recording all
telephone transactions; and providing written confirmation thereof to the Owner
or Participant and any agent of record, at the last address of record. Failure
to follow reasonable procedures may result in the Company's liability for any
losses due to unauthorized or fraudulent telephone transfers. However, any
losses incurred pursuant to actions taken by the Company in reliance on
telephone instructions reasonably believed to be genuine shall be borne by the
Participant. The Company may determine to withdraw the Telephone Exchange
Privilege, upon 30 days written notice to Contract Owners and Participants.

     On the date the Company receives an exchange request in good order, which
includes all of the information necessary for processing the request, the
Company will transfer the amount to be converted. Such transfers will be based
on the Accumulation Unit Values of the affected Sub-Accounts if received at the
Company's Home Office by the close of the New York Stock Exchange on a day on
which the New York Stock Exchange is open for business. If the exchange request
is received after the close of the New York Stock Exchange on any day, or on a
day the New York Stock Exchange is closed for business, the transfer will be
based on the next business day on which the New York Stock Exchange is open.

     For those Plans funded by this Contract and Nationwide's Group Fixed Fund
Retirement Contract, the Owner, or the Participant if the Plan so provides, may
exchange Accumulation Units between any Sub-Account of the NACo Variable Account
and the Group Fixed Fund Retirement Contract. Exchanges from the deposit fund to
any Sub-Account of the NACo Variable Account will be subject to the limitations
of the Group Fixed Fund Retirement Contract. Exchanges will be effected when
received in good order by the Company at its Home Office.

SUSPENSION AND TERMINATION

     The Contract may be suspended at the option of the Company on written
notice to the Owner if: (a) the Owner has failed to remit to the Company any
Purchase Payment specified in the Plan; or (b) if the Company does not accept an
amendment to the Plan, filed with the Company by the Owner, which in the
Company's opinion would adversely affect its financial experience with respect
to the Contract. The Owner may suspend the Contract upon 90 days written notice
to the Company. Suspension of the Contract will become effective as of the
ninety-first (91st) day following receipt of written notice by the Company.
Suspension of the Contract shall mean only that no further Purchase Payments
will be accepted by the Company except by mutual consent, and all other terms of
the Contract shall continue to apply. After suspension of the Contract has
become effective, the Owner may, upon 30 days written notice, terminate the
Contract. Termination of the Contract will become effective as of the 31st day
following receipt of written notice by the Company. Upon termination of the
Contract, the Company will pay to the Owner the redemption value, subject to
applicable charges, plus the balance of the annual premiums transferred from the
NACo Variable Account to the General Account for payment of variable Retirement
Income benefits under retirement Options B1 and B2 (see "Optional Retirement
Income Forms"). Payment of redemption values may be suspended when redemption of
Underlying Mutual Fund shares are suspended as provided in the section entitled
"Redemption of Participant Accounts." Payment of any amounts under this section
will be subject to any applicable CDSC (see "Contingent Deferred Sales Charge").
Upon such termination by the Owner, payment of Contract Values will be subject
to any applicable Contingent Deferred Sales Charge.

APPLICATION OF PURCHASE PAYMENTS

     The Company shall receive Purchase Payments from the Owner in accordance
with the requirements of the Plan. Net Purchase Payments received on behalf of
Participants will be applied by the Company to purchase Accumulation Units of
Sub-Accounts in the NACo Variable Account in accordance with the instructions of
the Owner. Purchase Payments made at any time by or on behalf of each
Participant must be at least $20 per month. Payments must be no less than
monthly, unless agreed to by the Company.

     An initial Purchase Payment will be priced not later than 2 business days
after receipt of an order to purchase, if the application of the Participant and
all information necessary for processing the purchase order are complete upon
receipt by the Company. The Company may retain the Purchase Payment for up to 5
business days while attempting to complete an incomplete application. If the
application cannot be made complete within 5 business days, the Owner will be
informed of the reasons for the delay and the Purchase Payment will be returned
immediately unless the Owner consents to the Company retaining the Purchase
Payment until the application of the Participant is made complete. Upon
completion of such incomplete application, the Purchase Payment will be priced
within 2 business days. Purchase Payments will not be priced on days when the
New York Stock Exchange is not open for business.

ADDITIONAL PURCHASE PAYMENT PRIOR TO COMMENCEMENT OF ANNUITY PAYMENTS

     The Owner shall have the right to make one additional Purchase Payment in
respect to a Participant for the purpose of increasing Retirement Income
Payments. Notice of such payment shall be given to the Company at the time the
notice to distribute is given, and such additional Purchase Payment must be made
no later than the last business day prior to the date upon which Retirement
Income Payments are to commence. Any such additional Purchase Payment shall be
subject to any applicable premium taxes. The annuity rates provided under this
Contract at the time of issue shall be applicable to the entire value, including
any such additional Purchase Payment, of such account which does not exceed five
times the Purchase Payment allocated to such account prior to the date notice to
distribute is given. Any excess amount may be applied at annuity rates then
offered by the Company for contracts of the same type as this Contract.

CREDITING ACCUMULATION UNITS

     When a Purchase Payment is received by the Company, the net Purchase
Payment for each Sub-Account is applied separately to provide Accumulation Units
which are credited to a Participant Account in accordance with the 


                                      19

                                   24 of 134
<PAGE>   25


instructions of the Owner. The number of Accumulation Units (calculated daily)
credited to each Participant Account for each Sub-Account is determined by
dividing the net Purchase Payment allocated to that Sub-Account for that
Participant by the value of the Accumulation Unit for that Sub-Account next
computed following of the Purchase Payment by the Company. The net Purchase
Payment for each Participant is the total Purchase Payment for that Participant
less any taxes then payable.

NACO VARIABLE ACCOUNT ACCUMULATION UNIT VALUE

     The value of an Accumulation Unit for each Sub-Account was established at a
value equal to the accumulation unit value of the corresponding Sub-Account of
the Nationwide DC Variable Account on January 2, 1990. The Nationwide DC
Variable Account is a segregated investment account of the Company in which
Member Counties formerly held Contracts. The value of an Accumulation Unit for
each new Sub-Account added to the NACo Variable Account after January 2, 1990,
will be established at $1.00 as of the date Underlying Mutual Fund shares are
available for purchase for that Sub-Account. The value of Accumulation Units for
any Sub-Account for any subsequent business day is determined by multiplying the
value for the preceding business day by the Net Investment Factor for that
Sub-Account for the period since that day (see the section entitled "Net
Investment Factor"). A business day is any day on which the New York Stock
Exchange is open for trading or any other day during which there is a sufficient
degree of trading of the Underlying Mutual Fund shares that the current net
asset value of their Accumulation Units might be materially affected.
Accumulation Units are calculated on a daily basis.

ALLOCATION OF PURCHASE PAYMENTS

     The Owner or Participant must specify the proportion of the Purchase
Payments to be applied to provide benefits under any Sub-Account of the NACo
Variable Account. The Company will permit the Owner, or the Participant if the
Plan so permits, to change the allocation percentages among Sub-Accounts for
subsequent Purchase Payments, provided that no change may be made which would
result in an amount less than 1% of the payment being allocated to any
Sub-Account for any Participant. The Company will permit such allocation changes
as frequently as permitted by the Plan. A change in allocation percentages will
not affect Accumulation Units of any Sub-Account resulting from Purchase
Payments made before the change.

VALUATION OF AN ACCOUNT

     The sum of the value of all Accumulation Units credited to the Participant
Account in respect of the Participant is the Participant Account Value. Purchase
Payments are allocated among the Sub-Accounts of the NACo Variable Account in
accordance with the instructions of the Owner.

     The value of a Participant's Account on any day can be determined by
multiplying the total number of Accumulation Units credited to the account for
each Sub-Account by the current Accumulation Unit Value for that Sub-Account in
respect of the Participant. Each Participant and the 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. Such reports to Participants are for informational
purposes only and should not be interpreted to mean that a Participant has any
rights with respect to his or her account beyond that provided by the Owner in
accordance with the terms of the Plan.

     The Participant and Owner should review the information in these reports
carefully. All errors or corrections must be reported to the Company immediately
to assure proper crediting to the Contract and appropriate Sub-Accounts. The
Company will assume all transactions are accurate unless the Participant or the
Owner notifies the Company otherwise within 30 days after receipt of the report.

     The principal underwriter and distributor of the Contracts is Nationwide
Advisory Services, Inc. ("NAS"), One Nationwide Plaza, Columbus, Ohio, 43215.

REDEMPTION OF PARTICIPANT ACCOUNTS

     The Owner's right to redeem Participant Accounts, either fully or
partially, will be governed by the terms of the Plan which the Contract is
issued to fund. It should be recognized that the value of the investment on
redemption can be more or less than its cost. All such payments will be made by
the Company to the Owner. It is the Owner's obligation to distribute such
payments to a Participant. The Company may undertake the obligation on behalf of
the Owner to distribute such payments directly to a Participant by agreement
with the Owner. To the extent permitted by the Plan, a Participant Account may
be redeemed fully or partially at any time prior to the date Retirement Income
Payments commence for the Participant under either Option B1 or B2. No partial
redemption will directly affect 


                                      20

                                   25 of 134
<PAGE>   26


future requirements to make Purchase Payments for that Participant nor his or
her retirement date. If the Contract is terminated by the Owner, all Participant
Accounts in the NACo Variable Account will be redeemed to the extent permitted
by the Plan, and such Participant Accounts will be subject to any applicable
CDSC. However, absent Contract termination by the Owner, the CDSC provision will
not apply and therefore any full or partial redemptions made on behalf of a
Participant will not be subject to any CDSC (see "Contingent Deferred Sales
Charge").

     A request for a partial redemption of a Participant Account containing more
than one Sub-Account of Accumulation Units must specify the allocation of the
partial redemption among the Sub-Accounts of Accumulation Units. However, if no
such direction is contained in the request for a partial redemption, the Company
may pro-rate the redemption among the applicable Sub-Accounts of Accumulation
Units. Upon receipt at the Company's Home Office of a written request for a full
or partial redemption of a Participant Account, the Company will determine the
value of the number of Accumulation Units redeemed at the Accumulation Unit
Value next computed following receipt of such written request by the Company.
Payment of any such amount will be made to the Owner with reasonable promptness,
and in any event, within 7 days of the date the request is received by the
Company. Payment of redemption values may be suspended when redemption of the
Underlying Mutual Fund shares is suspended (i) during any period in which the
New York Stock Exchange is closed, or (ii) in the event that the Securities and
Exchange Commission may by order direct for the protection of Owners or
Participants. Instead of a lump sum Distribution of a full or partial
redemption, the Owner, or Participant if permitted by the Plan, may elect to
have that amount paid out in installments under Option A1 or A2, subject to the
minimums applicable to these options.

            DISTRIBUTION OF PARTICIPANT ACCOUNTS (RETIREMENT PERIOD)

RETIREMENT INCOME PAYMENTS

     The period during which a Participant Account is paid out in periodic
installments is known as the Distribution Period. Because periodic Distributions
will normally be made after the Participant retires, the Distribution Period is
also called the retirement period. All such periodic Distributions will be made
by the Company to the Owner. It is the Owner's obligation to pay such amounts to
a Participant. The Company may undertake the obligation on behalf of the Owner
to pay such amounts directly to a Participant by agreement with the Owner.
Retirement Income Payments under Options B1 and B2 are determined on the basis
of (i) the mortality tables specified in the Contract, (ii) the adjusted age of
the Retired Participants, (iii) the type of Retirement Income Payment option(s)
selected, and (iv) in the case of variable payments, the investment performance
of the specific NACo Variable Account Sub-Account elected. While the Company may
be obligated to make variable Retirement Income Payments under the Contract, the
amount of each such payment is not guaranteed. The dollar amount of variable
payments will reflect investment gains and losses, and investment income of the
NACo Variable Account Sub-Account on which they are based, but they will not be
affected by adverse mortality experience or by an increase in the Company's
expenses above the amount provided for in the Contracts.

ELECTION OF INCOME FORM AND DATE

     The Contracts provide for Retirement Income Payments to begin on the date
and under the retirement options elected in accordance with the Plan. At least
one month prior to a Participant's Retirement Commencement Date (see "Glossary
of Terms"), the Contract Owner may by written election to the Company at its
home office, elect any one of the retirement income options described in this
prospectus. The Plan may restrict changes in election of retirement income
options.

ALLOCATION OF RETIREMENT INCOME

     Upon retirement, Accumulation Units in a Participant's Account may be used
to purchase a fixed dollar annuity for the Participant. For Participants
electing Options A1 or A2 as described in this prospectus, Accumulation Units in
a Participant's Account of any Sub-Account in the NACo Variable Account will be
used to provide variable Retirement Income Payments as described further in this
prospectus.

FIXED DOLLAR ANNUITY

     A Fixed Dollar Annuity is an annuity with payments which are guaranteed as
to dollar amount during the retirement period. The first fixed dollar payment
will be determined by applying the value of the General Account contract to the
applicable Annuity Table in accordance with the Optional Retirement Income Form
elected. This will be done at the retirement date. Fixed dollar annuity payments
after the first will not be less than the First Fixed Dollar 

                                      21

                                   26 of 134
<PAGE>   27


Annuity payment. The availability of fixed dollar annuity contracts under a
particular Plan is subject to the election of the Owner.

MINIMUM PAYMENT

     If the present value of the Participant's accrued benefit at the time of
retirement is less than $3,500, the Company shall have the right to make a lump
sum Distribution to such Retired Participant.

DEATH BENEFIT BEFORE RETIREMENT

     In the event a Participant dies before his or her retirement income
commences, a death benefit equal to the value of such Participant Account will
be paid as provided by the Plan upon (1) the Company's receipt and verification
of proof of death; and (2) the Company's verification of Beneficiary
designations. If the Plan so provides, a Beneficiary may elect either to receive
such value in a lump sum or to apply it under any of the Optional Retirement
Income Forms contained in the Contract, subject to the minimums applicable to
such optional forms. Monthly payments due under such options may be fixed,
variable, or a combination of fixed and variable.

OPTIONAL RETIREMENT INCOME FORMS

     The availability of the following Optional Retirement Income Forms are
subject to the election of the Owner:

     OPTION A1- Payments for a Designated Period. Payments will be made monthly
for any specified number of years not to exceed 30 years. The amount of each
variable payment will be determined by multiplying (a) by (b) where (a) is the
Accumulation Unit Value for the date the payment is made and (b) is the number
of Accumulation Units applied under this option divided by the number of
payments selected. Exchanges between the investment options are permitted
subject to limitations outlined in the Company's Group Fixed Fund Retirement
Contract. A period certain payment period of less than 5 years for a Participant
who has less than a minimum of 5 Participant Account Years would result in
imposition of the applicable Contingent Deferred Sales Charge.

     OPTION A2 - Payments of a Designated Amount. Payments will be made monthly
in equal installments (not less than $25 per month) until the amount applied,
adjusted each Valuation Date for investment results, is exhausted. The final
installment will be the sum remaining with the Company. Payments under this
option which result in a payment period of less than 5 years for a Participant
who has less than 5 Participant Account Years would result in imposition of the
applicable Contingent Deferred Sales Charge. Exchanges between the investment
options are permitted subject to limitations outlined in the Company's Group
Fixed Fund Retirement Contract.

     OPTION B1- Life Income with Payment Certain. Payments will be made monthly
during the lifetime of an individual with payments made for a period certain of
60, 120, 180, 240, 300 or 360 months as elected. If the individual dies before
the end of the period certain, level payments will continue to the designated
Beneficiary during the remainder of the selected period certain.

     OPTION B2-Joint and Survivor Life Income. Payments will be made monthly
during the joint lifetime of a Participant and a designated Beneficiary.
Payments will continue to be made as long as either is living. This option will
permit the choice of 100%, 75%, 66 2/3% or 50% of the original payment amount to
be paid to the Beneficiary. Payments will stop with the last payment due prior
to the death of the Beneficiary. If the Beneficiary predeceases the designated
Annuitant, then payments continue at 100% to the designated Annuitant.


     OTHER FORMS AND BENEFIT PAYMENTS - With the consent of the Company, the
amount due upon Distribution may be applied on any other mutually agreeable
basis.

     Exchanges processed while Participants are receiving payments under Options
A1 may change the number of Accumulation Units remaining. In this event, the
payment amount must be recalculated.

     On the date on which Retirement Income Payments under Option B1 or B2 or
any other Retirement Income Payment measured by a life or lives commence in
respect of a Participant, all Accumulation Units (or the number thereof
appropriate to the election made) in any Sub-Account will be canceled.

                                      22

                                   27 of 134
<PAGE>   28

DEATH OF RETIRED PARTICIPANT

     If any Retired Participant dies while receiving payments, any death benefit
payable will be determined in accordance with the Retirement Income Form
elected. Calculation of the present value of any remaining payments certain for
purposes of making a lump sum payment will be based on the same assumed
investment rate used by the Company in determining the payments certain prior to
the death of the Retired Participant.

WITHDRAWAL

     If permitted by the Plan, any amount remaining under Option A1 or A2 may be
withdrawn, or if that amount is at least $5,000, it may be applied under either
Option B1 or B2, subject to the minimum payment requirements described
previously. Unless prohibited by the Plan, a Beneficiary receiving payments
certain under Option B1 after the death of a Retired Participant may elect at
any time to receive the present value at the current dollar amount of the
remaining number of payments certain in a single payment, calculated on the
basis of the assumed investment rate used in computing the amount of the
previous payments.

FREQUENCY OF PAYMENT

     At the election of the Retired Participant, and with the consent of the
Owner, payments made under any option may be made annually, semi-annually, or
quarterly instead of monthly. Any change in frequency of payments must be on the
anniversary of the commencement of Retirement Income Payments.

DETERMINATION OF PAYMENTS UNDER OPTIONS A1 AND A2

     Monthly payments under Options A1 and A2 will be determined in the manner
set forth in the description of the options. As each payment is made under
either of these options, a number of Accumulation Units equal in value to the
payment will be canceled.

DETERMINATION OF PAYMENTS UNDER OPTIONS B1 AND B2

     Variable monthly payments under Options B1 and B2 will be determined
annually and will remain level throughout the year. Each year, as of the
anniversary of the commencement of Retirement Income Payments, a new variable
monthly payment will be determined and that new payment will remain level for
that year. An adjusted age is used to determine the amount of monthly payment
for each year. Such adjusted age may not be the same as the actual age of the
Retired Participant.

DETERMINATION OF AMOUNT OF VARIABLE MONTHLY PAYMENTS FOR FIRST YEAR

     In determining the amount of Retirement Income Payments under Options B1
and B2, the value held on behalf of a Participant is determined by multiplying
the number of Accumulation Units in each Sub-Account for that account by the
Accumulation Unit value for that Sub-Account on the last business day of the
second calendar week immediately preceding the date on which the first payment
is due.

     The first year variable monthly payment for each Sub-Account is determined
by dividing the value of the Accumulation Units of that Sub-Account in the
Participant Account by the amount required to provide $1 per month (the purchase
rate).

     Once the first year's variable monthly payment amount has been determined
for a Participant, the Company will deduct the annual premium from the
Participant Account. This deduction is made by canceling a number of
Accumulation Units in the Participant Account equal in value to the annual
premium. The allocation of the annual premium between Sub-Account will be in
such relationship as the monthly payments from each Sub-Account have to each
other.

     The annual premium is calculated so that if there are no partial
redemptions (and therefore no Underlying Mutual Fund dividends have been taken
in cash) the payee will receive level annual payments if the net investment
factor, on an annual basis, is equal to the Assumed Investment Rate plus an
amount equal to the annual administrative charge. Payments for subsequent years
will be smaller than, equal to, or greater than the payments received during the
initial year, depending on whether the actual net investment result on an annual
basis of a Sub-Account is smaller than, equal to, or greater than the Assumed
Investment Rate.

                                      23

                                   28 of 134
<PAGE>   29


DETERMINATION OF AMOUNT OF VARIABLE MONTHLY PAYMENTS FOR THE SECOND AND
SUBSEQUENT YEARS

     As of the first anniversary of the commencement of Retirement Income
Payments, the second year variable monthly payments will be determined in
exactly the same manner as for the first year, using the purchase rates in the
Contract for the Retired Participant's age as then determined under the terms of
the Contract. As in the first year, an annual premium will be deducted and
transferred to the General Account from which Account the Company will make the
Retirement Income Payments. Subsequent annual determinations will be made in the
same manner.

     Upon the death of any Retired Participant, 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. Any Accumulation Units so canceled will either remain in
the NACo Variable Account or be transferred to the Company's General Account,
depending on the Company's obligation.

ALTERNATE ASSUMED INVESTMENT RATE


     The Contracts include purchase rates based on a 3.5% rate per annum. If not
prohibited by the laws and regulations of the states in which this Contract is
issued, an Owner may elect on the Contract Date to have all variable benefits
payable for all Participants determined on an Assumed Investment Rate of 5% per
annum. The Assumed Investment Rate basis in the Contract is used merely to
determine each year's periodic payment from investment experience of any of the
NACo Variable Account Sub-Accounts. The choice of the Assumed Investment Rate
affects the pattern of Retirement Income Payments. A higher Assumed Investment
Rate will produce a higher initial year payment, but a more slowly rising series
of subsequent payments (or a more rapidly falling series of subsequent payments)
than a lower Assumed Investment Rate.

     Although a higher initial payment would be received under a higher Assumed
Investment Rate, there is a point in time after which payments under a lower
Assumed Investment Rate would be greater, assuming payment continues after that
point in time.

     The objective of a variable retirement Contract is to provide level
payments during periods when the economy is relatively stable and to reflect as
increased payments only the excess of investment results flowing from inflation
or an increase in productivity. The achievement of this objective will depend in
part upon the validity of the assumption that the net investment result, on an
annual basis, of a Sub-Account equals the Assumed Investment Rate during periods
of stable prices.

                               GENERAL INFORMATION

SUBSTITUTION OF SECURITIES

     If the shares of any Underlying Mutual Fund should no longer be available
for investment by the NACo Variable Account or, if in the judgment of the
Company's management, further investment in such Underlying Mutual Fund shares
should become inappropriate in view of the purposes of the Contract, the Company
may substitute shares of another Underlying Mutual Fund for Underlying Mutual
Fund shares already purchased or to be purchased in the future by Purchase
Payments under the Contract.

     From time to time it may become necessary for the Company to substitute
Underlying Mutual Fund shares for reasons relating to the historical investment
performance of the Underlying Mutual Funds. The Company, in consultation with
NACo and NACo's advisers, has developed standards for substituting Underlying
Mutual Funds that consistently experience poor investment performance over time.
These standards involve comparing the performance of each Underlying Mutual Fund
within the NACo Variable Account to the performance of all other mutual funds
within the Underlying Mutual Fund's same risk category. Underlying Mutual Funds
within the same risk category are Underlying Mutual Funds with similar
investment objectives and policies, and similar volatilities of investment
return.

     In no event will any substitution of securities in the NACo Variable
Account take place without prior approval of the Securities and Exchange
Commission, and under such requirements as the Commission may impose.

PERFORMANCE ADVERTISING

     The Company may from time to time advertise several types of historical
performance for the Sub-Accounts of the NACo Variable Account. A "yield" and
"effective yield" may be advertised for the Nationwide Money Market Fund and the
Short-Term Investments Trust Treasury Portfolio Sub-Account. "Yield" is a
measure of the net dividend and 

                                      24

                                   29 of 134
<PAGE>   30


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 Sub-Accounts' units. Yield is an annualized figure, which means that it is
assumed that the Sub-Account generates the same level of net income each week
over a 52-week period. The "effective yield" is calculated similarly but
includes the effect of assumed compounding calculated under rules prescribed by
the Securities and Exchange Commission. The effective yield will be slightly
higher than yield due to this compounding effect.

     The Company may also advertise for the Sub-Account standardized "average
annual total return", calculated in a manner prescribed by the Securities and
Exchange Commission, and non-standardized "total return." "Average annual total
return" will show the percentage rate of return of a hypothetical initial
investment of $1,000 for rolling calendar quarters and will cover, at least the
most recent one, five and ten year periods, or for a period from inception to
date if the Underlying Mutual Fund held in the Sub-Account has not been in
existence for one of the prescribed periods. This calculation reflects the
deduction of all applicable charges made to the Contracts except for premium
taxes, which may be imposed by certain states. Non-standardized "total return"
will be calculated in a similar manner as will average annual total return
except total return will not reflect the deduction of any applicable Contingent
Deferred Sales Charge, which, if reflected, would decrease the level of
performance shown.

     The Company may also from time to time advertise the performance of the
Sub-Accounts of the NACo Variable Account relative to the performance of other
variable annuity sub-accounts or mutual funds with similar or different
objectives, or the investment industry as a whole.

     The Sub-Accounts of the NACo Variable Account may also be compared to
certain market indexes which may include, but are not limited to: S&P 500;
Shearson/Lehman Intermediate Government/Corporate Bond Index; Shearson/Lehman
Long-Term Government/Corporate Bond Index; Donoghue Money Fund Average; U.S.
Treasury Note Index; and Dow Jones Industrial Average.

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

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

NET INVESTMENT FACTOR

     The Net Investment Factor for any Valuation Period is determined by
dividing (a) by (b) and subtracting (c) from the result where:

(a)  is the net of

     (1)   the net asset value per share of the Underlying Mutual Fund held in
           the Sub-Account determined at the end of the current Valuation
           Period, plus

     (2)   the per share amount of any dividend or capital gain distributions
           made by the Underlying Mutual Fund held in the Sub-Account if the
           "ex-dividend" date occurs during the current Valuation Period, plus
           or minus

     (3)   a per share charge or credit, if any, for any taxes reserved for
           which is determined by the Company to have resulted from the
           investment operations of the Sub-Account.

 (b) is the net of

     (1)   the net asset value per share of the Underlying Mutual Fund held in
           the Sub-Account determined as of the end of the immediately preceding
           Valuation Period, plus or minus

     (2)   the per share charge or credit for any taxes reserved for in the
           immediately preceding Valuation Period.

(c)  is a factor representing the daily Actuarial Risk Fee deducted from the
     NACo Variable Account. Such factor is equal to an annual rate of up to
     0.95% of the daily net asset value of the NACo Variable Account.

     For Underlying Mutual Funds that credit dividends on a daily basis and pay
such dividends once each month or quarter (such as money market funds and
certain bond funds), the Net Investment Factor allows for the monthly or
quarterly reinvestment of these daily dividends.

     The Net Investment Factor may be greater or less than one, therefore, the
value of an Accumulation Unit may increase or decrease. It should be noted that
changes in the Net Investment Factor may not be directly proportional to changes
in the net asset value of Underlying Mutual Fund shares, because of the
deduction for the Actuarial Risk Fee and the effect of the various purchase and
sale transactions on any particular day.

VALUATION OF ASSETS

     Underlying Mutual Fund shares in the NACo Variable Account will be
purchased and valued at their net asset value (daily bid price exclusive of any
sales charges). An Underlying Mutual Fund's net asset value per share is
determined by dividing the value of the total assets of the Underlying Mutual
Fund, less liabilities, by the number of shares outstanding, with no charge for
sales expense.

FEDERAL TAX STATUS

     The following description of the federal tax status of these Contracts is
not exhaustive, and special rules are provided with respect to situations not
discussed herein. For complete information, consult a qualified tax Adviser. The
Company does not make any guarantee regarding the tax status of any Contract or
any transaction involving the Contracts. The Contracts are treated as a trust
for purposes of the Code under rules similar to the rules under Section 401(f)
of the Code.

     For federal income tax purposes, the operations of the NACo Variable
Account form a part of the Company's operations. Under existing federal income
tax law, no taxes are payable by the Company on the investment income of the
NACo Variable Account to the extent it is credited to the Owners under the
Contracts. The Company is taxed as a life insurance company under Part One,
Subchapter L, of the Code.

     Income and capital gains of the NACo Variable Account would normally be
taxable to Owners whether or not taken by the Owners in cash. However, the
Contracts are issued only to organizations exempt from federal income tax.

     The amounts received by the Participant under the Plan normally represent
the accumulation of Purchase Payments which were not previously included in the
Participant's gross income, and therefore any such amounts should be included in
gross income of a Participant or Beneficiary when such amounts are received.

     It is the responsibility of each Owner to determine that its Plan is
established and administered in accordance with the applicable provisions of the
Code.

CONTRACTS ISSUED UNDER THE NEW YORK MODEL PLAN

     The following Contract amendments are required by the Rules and Regulations
of the New York State Deferred Compensation Board in order to market the
Contracts to governmental employers for use in funding public employee deferred
compensation plans in the State of New York.

     Throughout the prospectus, references to "annuity" payments are modified to
"benefit" payments.

     The "Suspension and Termination" provisions are amended to permit a
Participant to "freeze" his or her account and maintain the account on deposit
with the Company notwithstanding the Contract Owner's termination of its
contractual relationship with the Company. These accounts shall remain the
exclusive property of the Contract Owner, subject to the claims of its general
creditors.

     All references throughout the prospectus to Life Income Options B1 and B2
are deleted. All references to "Contingent Deferred Sales Charge" are deleted.

                                LEGAL PROCEEDINGS

         From time to time the Company 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 the Company.


         In recent years, life insurance companies have been named as defendants
in lawsuits, including class action lawsuits, relating to life insurance pricing
and sales practices. A number of these lawsuits have resulted in substantial
jury awards or settlements. In October 1996, a policyholder of Nationwide Life
filed a complaint in Alabama state court against Nationwide Life and an agent of
Nationwide Life (Wayne M. King v. Nationwide Life Insurance Company and Danny
Nix), related to the sale of a whole life policy on a "vanishing premium" basis
and seeking unspecified compensatory and punitive damages. In February 1997,
Nationwide Life was named as a defendant in a lawsuit filed in New York Supreme
Court also related to the sale of whole life policies on a "vanishing premium"
basis (John H. Snyder v. Nationwide Mutual Insurance Company, Nationwide Mutual
Insurance Co. and Nationwide Life Insurance Co.). The plaintiff in such lawsuit
seeks to represent a national class of Nationwide Life policyholders and claims
unspecified compensatory and punitive damages. This lawsuit is in an early stage
and has not been certified as a class action. Nationwide Life intends to defend
these cases vigorously. There can be no assurance that any future litigation
relating to pricing and sales practices will not have a material adverse effect
on the Company.


     The General Distributor, Nationwide Advisory Services, Inc., is not engaged
in any litigation of any material nature.

that the portfolio will generally consist of common stocks of medium-sized and
smaller companies. American Century Investment Services, Inc. serves as the

THE DREYFUS THIRD CENTURY FUND, INC.

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

Dreyfus Corporation 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 CONTRAFUND

         The investment objective of the Fund is capital appreciation by
investing in securities that its manager believes are undervalued due to an
overly pessimistic appraisal by the public. Although the Fund will usually be
invested primarily in common stocks and securities convertible into common
stock, the percentage of its assets invested in other securities may vary.
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 MAGELLAN(R) FUND

         The investment objective of the Fund is capital appreciation by

risks. The Fund may also invest in stock index futures and options both of which
can be volatile investments. Fidelity Management & Research Company serves as

possible, consistent with the preservation and conservation of capital, by

offering a better than average yield may also possess some growth possibilities.
Fidelity Management & Research Company serves as the Fund's investment Adviser.

MAS FUNDS FIXED INCOME PORTFOLIO

income securities, some of which may involve equity features. Securities
offering the high current income sought by this Fund are ordinarily in the lower
rating categories of recognized rating agencies or are unrated and generally
involve greater volatility of price and risk of principal and income than
securities in the high rating categories. Capital growth, if any, is a
consideration incidental to the investment objective of high current income.

Adviser.

NATIONWIDE(R) FUND

serves as the Fund's investment Adviser.

Management serves as the Fund's investment Adviser.

Nationwide Life Insurance Company (the "Company"). The Company is a member of
the Nationwide Insurance Enterprise and all of the Company'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 (95.2%) and
Nationwide Mutual Fire Insurance Company (4.8%), the ultimate controlling
persons of Nationwide Insurance Enterprise.

SERVICES

         The Company has responsibility for administration of the Contracts and
the NACo Variable Account, maintaining records, including name, address,
taxpayer identification number, and other pertinent information for each Owner
and the number and type of Contracts issued to each such Owner and the Contract
Value of each Contract.

         All assets of the NACo Variable Account are held in custody for
safekeeping by the Company. 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. The
Company will maintain a record of all and redemption for shares of the
Underlying Mutual Fund held in each Sub-Account.

         The Company, or affiliates of the Company 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 the Company or an affiliate of the Company and provide for an
annual fee based on the average aggregate net assets of the Variable Account
(and other separate accounts of the Company or life insurance company
subsidiaries of the Company) 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.

reliance upon the reports of KPMG Peat Marwick LLP, independent certified public
accountants, Two Nationwide Plaza, Columbus, Ohio 43215, and upon the authority

Contract. Exchanges from the deposit fund to any Sub-Account of the NACo
Variable Account will be subject to the limitations of the Group Fixed Fund
Retirement Contract Exchanges will be effected when received in good order by
the Company at its Home Office.

UNDERWRITERS

         The Contracts, which are offered continuously, are distributed by
Nationwide Advisory Services, Inc. ("NAS"), One Nationwide Plaza, Columbus, Ohio
43215, a wholly owned subsidiary of the Company. No underwriting commissions are
paid by the Company to NAS.

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 shall 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, 1996, the
Nationwide Money Market Fund and the Short-Term Investments Trust Treasury
Portfolio Sub-Accounts seven-day current yield were 3.89% and 4.52%
respectively. The Nationwide Money Market Fund and the Short-Term Investments
Trust Treasury Portfolio Sub-Accounts' 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,
1996 were 3.96% and 4.63%, 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'
portfolio, 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.

         All performance advertising shall include quotations of average annual
total return, calculated in accordance with a standard method prescribed by
rules of the Securities and Exchange Commission, to facilitate comparison with
total return quoted by other variable annuity separate accounts. Average annual
total return advertised for a specific period is found by first taking a
hypothetical $1,000 investment in each of the Sub-Accounts' units on the first
day of the period at the offering price, which is the Accumulation Unit Value
per unit ("initial investment") and computing the ending redeemable value
("redeemable value") of that investment at the end of the period. The redeemable
value is then divided by the initial investment and this quotient is taken to
the Nth root (N represents the number of years in the period) and 1 is
subtracted from the result which is then expressed as a percentage, carried to
at least the nearest hundredth of a percent. Average annual total return
reflects the deduction of a 0.95% Actuarial Risk Charge. The redeemable value
also reflects the effect of any applicable Contingent Deferred Sales Charge that
may be imposed at the end of the period (see "Contingent Deferred Sales Charge"
located in the prospectus.) No deduction is made for premium taxes which may be
assessed by certain states. Non-standardized total return is calculated in a
manner similar to average annual total return except the total return does not
reflect the deduction of any

applicable Contingent Deferred Sales Charge, which, if reflected, would decrease
the level of the performance advertised.

         The average annual total return and total return quotations will be
current to the last day of the calendar quarter preceding the date on which an
advertisement is submitted for publication. The standardized average annual
total return figures will be based on rolling calendar quarters and will cover,
at least, periods of one, five, and ten years, or a period covering the time a
Underlying Mutual Fund held in the Sub-Account has been in existence, if the
Underlying Mutual Fund has not been in existence for one of the prescribed
periods. The non-standardized total return will cover the cumulative current
calendar year and the most recently completed calendar year, and periods of
three, five and ten years on a rolling calendar quarter basis. For those
Underlying Mutual Funds which have not been held as Sub-Accounts within the NACo
Variable Account for one of the quoted periods, the standardized average annual
total return and non standardized total return quotations will show the
investment performance such Underlying Mutual Funds would have achieved (reduced
by the applicable charges) had they been held as Sub-Accounts within the NACo
Variable Account for the period quoted.

         Quotations of average annual total return and total return are based
upon historical earnings and will fluctuate. Any quotation of performance,
therefore, should not be considered a guarantee of future performance. Factors
affecting a Sub-Accounts' performance include general market conditions,
operating expenses and investment management. A Contract Owner's and
Participant's account when redeemed may be more or less than original cost

         Below are quotations of average annual total return and total return,
calculated as described above, for each of the non-money market Sub-Accounts
available within the NACo Variable Account.

                          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, 1996, and
the related statements of operations and changes in contract owners' equity and
schedules of changes in unit value for each of the years in the three year
period then ended. These financial statements and schedules of changes in unit
value are the responsibility of the Company's management. Our responsibility is
to express an opinion on these financial statements and schedules of changes in
unit value 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 and schedules of
changes in unit value 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, 1996, 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 and schedules of changes in unit
value referred to above present fairly, in all material respects, the financial
position of NACo Variable Account as of December 31, 1996, and the results of
its operations and its changes in contract owners' equity and the schedules of
changes in unit value for each of the years in the three year period then ended
in conformity with generally accepted accounting principles.

     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.

     (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, 1996. 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.

     (f) Reclassifications

     Certain 1995 and 1994 amounts have been reclassified to conform with the
current year presentation.

(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
participants 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.

     The following charges are 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:

                  II            Over $10 to $25              .40%
                  III           Over $25 to $50              .30%
                  IV               Over $50                  .20%
</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.

     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) SCHEDULE I

     Schedule I presents the components of the change in the unit values, which
are the basis for contract owners' equity. This schedule is presented in the
following format:

         o   Beginning unit value - Jan. 1

         o   Reinvested capital gains and dividends

             (This amount reflects the increase in the unit value due to
             capital gains and dividend distributions from the underlying
             mutual funds.)

         o   Unrealized gain (loss)

             (This amount reflects the increase (decrease) in the unit value
             resulting from the market appreciation (depreciation) of the
             underlying mutual funds.)

         o   Contract charges

             (This amount reflects the decrease in the unit value due to the
             mortality risk charge, expense risk charge and administration
             charge discussed in note 2.)

         o   Ending unit value - Dec. 31

         o   Percentage increase (decrease) in unit value.

                              NACo VARIABLE ACCOUNT

                          NOTES TO FINANCIAL STATEMENTS

                             JUNE 30, 1997 AND 1996
                                   (UNAUDITED)


(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

              Templeton Foreign Fund - Class I (TemForFd)

         All of the above funds were being utilized as of June 30, 1997.

         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.

     (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 June 30, 1997. 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.

     (f) Reclassifications

         Certain 1996 amounts have been reclassified to conform with the current
         year presentation.

(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.

     The following charges are 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:

                Expense                                 Administration
                 Tier          Assets (Millions)            Charge
                   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%

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

     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.

                          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) as of December 31,
1996 and 1995, 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, 1996.  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, 1996 and 1995, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1996, in conformity with generally accepted
accounting principles. 

In 1994, the Company adopted the provisions of the Financial Accounting
Standards Board's Statement of Financial Accounting Standards No. 115,
Accounting for Certain Investments in Debt and Equity Securities.

               NATIONWIDE LIFE INSURANCE COMPANY AND SUBSIDIARIES

                   Notes to Consolidated Financial Statements

                        December 31, 1996, 1995 and 1994
                                ($000's omitted)

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

         Nationwide Life Insurance Company (NLIC) is a wholly owned subsidiary
         of Nationwide Corporation (Nationwide Corp.). Wholly owned subsidiaries
         of NLIC include Nationwide Life and Annuity Insurance Company (NLAIC),
         Employers Life Insurance Company of Wausau and subsidiaries (ELICW),
         National Casualty Company (NCC), West Coast Life Insurance Company
         (WCLIC), Nationwide Advisory Services, Inc. (formerly Nationwide
         Financial Services, Inc.), Nationwide Investment Services Corporation
         (formerly PEBSCO Securities Corporation) (NISC) and NWE, Inc. NLIC and
         its subsidiaries are collectively referred to as "the Company."

         Nationwide Corp. formed Nationwide Financial Services, Inc. (NFS) in
         November 1996 as a holding company for NLIC and the other companies of
         the Nationwide Insurance Enterprise that offer or distribute long-term
         savings and retirement products. On January 27, 1997, Nationwide Corp.
         contributed to NFS the common stock of NLIC and three marketing and
         distribution companies. NFS is planning an initial public offering of
         its Class A common stock during the first quarter of 1997.

         In anticipation of the restructuring described above, on September 24,
         1996, NLIC's Board of Directors declared a dividend payable January 1,
         1997 to Nationwide Corp. consisting of the outstanding shares of common
         stock of certain subsidiaries (ELICW, NCC and WCLIC) that do not offer
         or distribute long-term savings and 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 ELICW and another affiliate effective January 1, 1996. These
         subsidiaries and all accident and health and group life insurance
         business have been accounted for as discontinued operations for all
         periods presented. See notes 2 and 13.

         In addition, as part of the restructuring described above, NLIC intends
         to make an $850,000 distribution to NFS which will then make an
         equivalent distribution to Nationwide Corp.

         The Company is a leading provider of long-term savings and retirement
         products to retail and institutional customers and is subject to
         competition from other financial services providers throughout the
         United States. The Company is subject to regulation by the Insurance
         Departments of states in which it is licensed, and undergoes periodic
         examinations by those departments.

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

              LEGAL/REGULATORY RISK is the risk that changes in the legal or
              regulatory environment in which an insurer operates will create
              additional expenses not anticipated by the insurer in pricing its
              products. That is, regulatory initiatives, new legal theories or
              insurance company insolvencies through guaranty fund assessments
              may create costs for the insurer beyond those currently recorded
              in the consolidated financial statements. 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.

              CREDIT RISK is 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.

               NATIONWIDE LIFE INSURANCE COMPANY AND SUBSIDIARIES

              Notes to Consolidated Financial Statements, Continued


              INTEREST RATE RISK is 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.

(2)      Discontinued Operations
         -----------------------

         As discussed in note 1, NFS is a holding company for NLIC and certain
         other companies that offer or distribute long-term savings and
         retirement products. Prior to the contribution by Nationwide Corp. to
         NFS of the outstanding common stock of NLIC and other companies, 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 to
         Nationwide Corp. 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
         that serves as a fronting company for a property and casualty
         subsidiary of Nationwide Mutual Insurance Company (NMIC), an affiliate.
         NCC maintains its offices in Scottsdale, Arizona. 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 for all periods presented. NLIC did not
         recognize any gain or loss on the disposal of these subsidiaries.

         A summary of the combined results of operations, including the results
         of the accident and health and group life insurance business ELICW
         assumed from NLIC in 1996, and assets and liabilities of ELICW, NCC and
         WCLIC as of and for the years ended December 31, 1996, 1995 and 1994 is
         as follows:

</TABLE>

         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 13 for a
         complete discussion of the reinsurance agreements. NLIC 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
         and will cease writing any new business prior to December 31, 1997.
         NLIC's accident and health and group life insurance business is
         accounted for as discontinued operations for all periods presented.
         NLIC 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 NLIC.

(3)      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 (GAAP) which
         differ from statutory accounting practices prescribed or permitted by
         regulatory authorities. Annual Statements for NLIC and its insurance
         subsidiaries, filed with the department of insurance of each insurance
         company's state of domicile, are prepared on the basis of accounting
         practices prescribed or permitted by each 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.

         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. Subsidiaries that are
              classified and reported as discontinued operations are not
              consolidated but rather are reported as "Investment in
              Subsidiaries Classified as Discontinued Operations" in the
              accompanying consolidated balance sheets and "Income for
              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, 1996 or 1995.

              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 are 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 annuities, annuities without life contingencies
              and guaranteed investment contracts. Universal life insurance
              products include universal life insurance, variable universal 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.

              ACCIDENT AND HEALTH INSURANCE PRODUCTS: Accident and health
              insurance premiums are recognized as revenue over the terms of the
              policies. Policy claims are charged to expense in the period that
              the claims are incurred. All accident and health insurance
              business is accounted for as discontinued operations. See note 2.

         (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 agency 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 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 3(b).

              Notes to Consolidated Financial Statements, Continued

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

              Separate Account assets and liabilities represent contractholders'
              funds which have been segregated into accounts with specific
              investment objectives. 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.

              Future policy benefits for traditional life insurance policies
              have been calculated using a net level premium method based on
              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. See note 6.

              Future policy benefits and claims for collectively renewable
              long-term disability policies and group long-term disability
              policies are the present value of amounts not yet due on reported
              claims and an estimate of amounts to be paid on incurred but
              unreported claims. The impact of reserve discounting is not
              material. Future policy benefits and claims on other group health
              insurance policies are not discounted. All health insurance
              business is accounted for as discontinued operations. See note 2.

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

              Participating business represents approximately 52% in 1996 (54%
              in 1995 and 55% in 1994) of the Company's life insurance in force,
              78% in 1996 (79% in 1995 and 79% in 1994) of the number of life
              insurance policies in force, and 40% in 1996 (47% in 1995 and 51%
              in 1994) of life insurance premiums. The provision for
              policyholder dividends is based on current dividend scales. Future
              dividends are provided for ratably in future policy benefits based
              on dividend scales in effect at the time the policies were issued.

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

              The Company, with the exception of ELICW, files a consolidated
              federal income tax return with 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. Through 1994, ELICW filed a
              consolidated federal income tax return with Employers Insurance of
              Wausau A Mutual Company, an affiliate. Beginning in 1995, ELICW
              files a separate federal income tax return.

              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 2 and 13.

         (j)  Reclassification
              ----------------

              Certain items in the 1995 and 1994 consolidated financial
              statements have been reclassified to conform to the 1996
              presentation.


(4)      Change in Accounting Principle
         ------------------------------

         Effective January 1, 1994, the Company changed its method of accounting
         for certain investments in debt and equity securities in connection
         with the issuance of STATEMENT OF FINANCIAL ACCOUNTING STANDARDS (SFAS)
         NO. 115 - ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY
         SECURITIES. As of January 1, 1994, the Company classified fixed
         maturity securities with amortized cost and fair value of $6,299,665
         and $6,721,714, respectively, as available-for-sale and recorded the
         securities at fair value. Previously, these securities were recorded at
         amortized cost. The effect as of January 1, 1994 has been recorded as a
         direct credit to shareholder's equity as follows:

         Proceeds from the sale of securities available-for-sale during 1996,
         1995 and 1994 were $299,558, $107,345 and $228,308, respectively.
         During 1996, gross gains of $6,606 ($4,838 and $3,045 in 1995 and 1994,
         respectively) and gross losses of $6,925 ($2,147 and $21,280 in 1995
         and 1994, respectively) were realized on those sales.

         During 1995, the Company transferred fixed maturity securities
         classified as held-to-maturity with amortized cost of $25,429 to
         available-for-sale securities due to evidence of a significant
         deterioration in the issuer's creditworthiness. The transfer of those
         fixed maturity securities resulted in a gross unrealized loss of
         $3,535.

         As permitted by the Financial Accounting Standards Board's Special
         Report, A GUIDE TO IMPLEMENTATION OF STATEMENT 115 ON ACCOUNTING FOR
         CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES, issued in November
         1995 the Company transferred all of its fixed maturity securities
         previously classified as held-to-maturity to available-for-sale. As of
         December 14, 1995, the date of transfer, the fixed maturity securities
         had amortized cost of $3,320,093, resulting in a gross unrealized gain
         of $155,940.

         Investments that were non-income producing for the twelve month period
         preceding December 31, 1996 amounted to $26,805 ($27,712 in 1995) and
         consisted of $248 ($6,982 in 1995) in fixed maturity securities,
         $20,633 ($14,740 in 1995) in real estate and $5,924 ($5,990 in 1995) in
         other long-term investments.

         Real estate is presented at cost less accumulated depreciation of
         $30,338 as of December 31, 1996 ($30,482 as of December 31, 1995) and
         valuation allowances of $15,219 as of December 31, 1996 ($25,819 as of
         December 31, 1995).

         The recorded investment of mortgage loans on real estate considered to
         be impaired (under SFAS NO. 114 - ACCOUNTING BY CREDITORS FOR
         IMPAIRMENT OF A LOAN as amended by SFAS NO. 118 - ACCOUNTING BY
         CREDITORS FOR IMPAIRMENT OF A LOAN-INCOME RECOGNITION AND DISCLOSURE)
         as of December 31, 1996 was $51,765 ($44,409 as of December 31, 1995),
         which includes $41,663 ($23,975 as of December 31, 1995) of impaired
         mortgage loans on real estate for which the related valuation allowance
         was $8,485 ($5,276 as of December 31, 1995) and $10,102 ($20,434 as of
         December 31, 1995) of impaired mortgage loans on real estate for which
         there was no valuation allowance. During 1996, the average recorded
         investment in impaired mortgage loans on real estate was approximately
         $39,674 ($22,181 in 1995) and interest income recognized on those loans
         was $2,103 ($387 in 1995), which is equal to interest income recognized
         using a cash-basis method of income recognition.

         Activity in the valuation allowance account for mortgage loans on real
         estate is summarized for the years ended December 31:

         various regulatory agencies as required by law.

(6)      Future Policy Benefits and Claims
         ---------------------------------

         The liability for future policy benefits for investment contracts
         represents approximately 87% and 87% of the total liability for future
         policy benefits as of December 31, 1996 and 1995, respectively. The
         average interest rate credited on investment product policies was
         approximately 6.3%, 6.6% and 6.5% for the years ended December 31,
         1996, 1995 and 1994, respectively.

         The liability for future policy benefits for traditional life insurance
         policies has been established based upon the following assumptions:

              WITHDRAWALS: Rates, which vary by issue age, type of coverage
              and policy duration, are based on Company experience.

              MORTALITY: Mortality and morbidity rates are based on
              published tables, modified for the Company's actual
              experience.

         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
         $240,451 and $245,255 as of December 31, 1996 and 1995, 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.

         The Company has reinsurance agreements with certain affiliates as
         described in note 13. All other reinsurance agreements are not material
         to either premiums or reinsurance recoverables.

         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, 1996, 1995 and 1994.

 (8)     Disclosures about Fair Value of Financial Instruments
         -----------------------------------------------------

         SFAS NO. 107 - DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
         (SFAS 107) requires disclosure of fair value information about existing
         on and off-balance sheet financial instruments. SFAS 107 defines the
         fair value of a financial instrument 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 based on estimates 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. SFAS 107 excludes certain assets and
         liabilities from its disclosure requirements. Accordingly, the
         aggregate fair value amounts presented do not represent the underlying
         value of the Company.

         Although insurance contracts, other than policies such as annuities
         that are classified as investment contracts, are specifically exempted
         from SFAS 107 disclosures, 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:

              CASH, SHORT-TERM INVESTMENTS AND POLICY LOANS: The carrying amount
              reported in the consolidated balance sheets for these instruments
              approximates their fair value.

              FIXED MATURITY AND EQUITY SECURITIES: 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.

              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 includes certain surrender
              charges.

              MORTGAGE LOANS ON REAL ESTATE: 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 mortgages in default is the estimated fair value of
              the underlying collateral.

              INVESTMENT CONTRACTS: 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 analyses. 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.

              POLICYHOLDERS' DIVIDEND ACCUMULATIONS AND OTHER POLICYHOLDER
              FUNDS: The carrying amount reported in the consolidated balance
              sheets for these instruments approximates their 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 9.

           Carrying amount and estimated fair value of financial instruments
           subject to SFAS 107 and policy reserves on life insurance contracts
           were as follows as of December 31, 1996 and 1995:

         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 $327,456 extending into
         1997 were outstanding as of December 31, 1996.

         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 21% (20% in 1995) in any geographic area and no more than 2% (2%
         in 1995) with any one borrower as of December 31, 1996.

         The Company had a significant reinsurance recoverable balance from one
         reinsurer as of December 31, 1996 and 1995. See note 6.

         The summary below depicts loans by remaining principal balance as of

(10)     Pension Plan
         ------------

         The Company is a participant, together with other affiliated companies,
         in a pension plan covering all employees who have completed at least
         one thousand hours of service within a twelve-month period and who have
         met certain age requirements. Benefits are based upon the highest
         average annual salary of a specified number of consecutive years of the
         last ten years 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.

         Effective January 1, 1995, the plan was amended to provide enhanced
         benefits for participants who met certain eligibility requirements and
         elected early retirement no later than March 15, 1995. The entire cost
         of the enhanced benefit was borne by NMIC and certain of its property
         and casualty insurance company affiliates.

         Effective December 31, 1995, the Nationwide Insurance Companies and
         Affiliates Retirement Plan was merged with the Farmland Mutual
         Insurance Company Employees' Retirement Plan and the Wausau Insurance
         Companies Pension Plan to form the Nationwide Insurance Enterprise
         Retirement Plan. Immediately prior to the merger, the plans were
         amended to provide consistent benefits for service after January 1,
         1996. These amendments had no significant impact on the accumulated
         benefit obligation or projected benefit obligation as of December 31,
         1995.

         Pension costs charged to operations by the Company during the years
         ended December 31, 1996, 1995 and 1994 were $7,381, $10,478 and
         $10,063, respectively.

         The Company's net accrued pension expense as of December 31, 1996 and
         1995 was $1,075 and $1,392, respectively.

         The net periodic pension cost for the Nationwide Insurance Enterprise
         Retirement Plan as a whole for the year ended December 31, 1996 and for
         the Nationwide Insurance Companies and Affiliates Retirement Plan as a

(11)     Postretirement Benefits Other Than Pensions
         -------------------------------------------

         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; 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,
         1996 and 1995 was $34,884 and $33,537, respectively, and the net
         periodic postretirement benefit cost (NPPBC) for 1996, 1995 and 1994
         was $3,286, $3,132 and $4,284, respectively.

         The health care cost trend rate assumption has an effect on the amounts

         the assumed health care cost trend rate would increase the APBO as of
         December 31, 1996 by $701 and the NPPBC for the year ended December 31,
         1996 by $83.

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

         Each insurance company'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 each of its
         insurance company subsidiaries exceed the minimum risk-based capital
         requirements.

         The statutory capital shares and surplus of NLIC as of December 31,
         1996, 1995 and 1994 was $1,000,647, $1,363,031 and $1,262,861,
         respectively. The statutory net income of NLIC for the years ended
         December 31, 1996, 1995 and 1994 was $73,218, $86,529 and $76,532,
         respectively.

         NLIC is limited in the amount of shareholder dividends it may pay
         without prior approval by the Department of Insurance of the State of
         Ohio (the Department). NLIC's dividend of the outstanding shares of
         common stock of certain companies which was declared on September 24,
         1996 and the anticipated $850,000 dividend (as discussed in note 1) are
         deemed extraordinary under Ohio insurance laws. As a result of such
         dividends, any dividend paid by NLIC during the 12-month period
         immediately following the $850,000 dividend would also be an
         extraordinary dividend under Ohio insurance laws. Accordingly, no such
         dividend could be paid without prior regulatory approval.

         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 stockholder.

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

(13)     Transactions With Affiliates
         ----------------------------

         The Company leases office space from NMIC and certain of its
         subsidiaries. For the years ended December 31, 1996, 1995 and 1994, the
         Company made lease payments to NMIC and its subsidiaries of $9,065,
         $8,986 and $8,133, 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 $101,584, $107,112, and $100,601 in 1996,
         1995 and 1994, 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
         intercompany 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 $15,111 and $1,186 as of December 31, 1996 and 1995,
         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 1996 and
         1995 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.

               NATIONWIDE LIFE INSURANCE COMPANY AND SUBSIDIARIES

              Notes to Consolidated Financial Statements, Continued

         Intercompany reinsurance contracts 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
         NLIC'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 NLIC's agreements, the investment risk associated
         with changes in interest rates is borne by NMIC or ELICW, as the case
         may be. Risk of asset default is retained by NLIC, although a fee is
         paid by NMIC or ELICW, as the case may be, to NLIC for the NLIC'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. NLIC believes that the terms of the modified coinsurance
         agreements are consistent in all material respects with what NLIC could
         have obtained with unaffiliated parties.

         Amounts ceded to ELICW in 1996 are included in ELICW's results of
         operations for 1996 which, combined with the results of WCLIC and NCC,
         are summarized in note 2. Amounts ceded to ELICW in 1996 include
         premiums of $224,224, net investment income and other revenue of
         $14,833, and benefits, claims and other expenses of $246,641. Amounts
         ceded to NMIC in 1996 include premiums of $97,331, net investment
         income of $10,890, and benefits, claims and other expenses of $100,476.

         The Company and various affiliates entered into agreements with
         Nationwide Cash Management Company (NCMC) and California Cash
         Management Company (CCMC), both affiliates, under which NCMC and CCMC
         act as common agents in handling the purchase and sale of short-term
         securities for the respective accounts of the participants. Amounts on
         deposit with NCMC and CCMC were $4,789 and $9,654 as of December 31,
         1996 and 1995, respectively, and are included in short-term investments
         on the accompanying consolidated balance sheets.

         On April, 5 1996, Nationwide Corp. contributed all of the outstanding
         shares, with shareholder equity value of $30, of NISC to NLIC. NLIC
         contributed an additional $500 to NISC on August 30, 1996.

         On March 1, 1995, Nationwide Corp. contributed all of the outstanding
         shares of common stock of Farmland Life Insurance Company (Farmland) to
         NLIC. Farmland merged into WCLIC effective June 30, 1995. The
         contribution resulted in a direct increase to consolidated
         shareholder's equity of $46,918. As discussed in note 2, WCLIC is
         accounted for as discontinued operations.

         Effective December 31, 1994, NLIC purchased all of the outstanding
         shares of common stock of ELICW from Wausau Service Corporation (WSC)
         for $155,000. NLIC transferred fixed maturity securities and cash with
         a fair value of $155,000 to WSC on December 28, 1994, which resulted in
         a realized loss of $19,239 on the disposition of the securities. The
         purchase price approximated both the historical cost basis and fair
         value of net assets of ELICW. ELICW has and will continue to share home
         office, other facilities, equipment and common management and
         administrative services with WSC. As discussed in note 2, ELICW is
         accounted for as discontinued operations.

         Certain annuity products are sold through three affiliated companies
         which are also subsidiaries of Nationwide Corp. Total commissions and
         fees paid to these affiliates for the years ended December 31, 1996,
         1995 and 1994 were $76,922, $57,280 and $50,168, respectively.

(14)     Bank Lines of Credit
         --------------------

         In August 1996, NLIC, along with NMIC, established a $600,000 revolving
         credit facility which provides for a $600,000 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.

(15)     Contingencies
         -------------

         The Company is a defendant in various lawsuits. In the opinion of
         management, the effects, if any, of such lawsuits are not expected to
         be material to the Company's financial position or results of
         operations.

(16)     Segment Information
         -------------------

         The Company has three primary 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 the Company and independent
         investment managers, with the investment returns accumulating on a
         tax-deferred basis. 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. The Life Insurance segment consists of
         insurance products that provide a death benefit and may also allow the
         customer to build cash value on a tax-deferred basis. In addition, the
         Company reports corporate expenses and investments, and the related
         investment income supporting capital not specifically allocated to its
         product segments in a Corporate and Other segment. In addition, all
         realized gains and losses, investment management fees and other revenue
         earned from mutual funds, other than the portion allocated to the
         variable annuities and life insurance segments, are reported in the
         Corporate and Other segment.

         During 1996, the Company changed its reporting segments to better
         reflect the way the businesses are managed. Prior periods have been
         restated to reflect these changes.

         The following table summarizes the revenues and income from continuing
         operations before federal income tax expense for the years ended
         December 31, 1996, 1995 and 1994 and assets as of December 31, 1996,
         1995 and 1994, by business segment.

(1)  Difference from Column B is primarily due to valuation allowances due to
     impairments on mortgage loans on real estate and due to accumulated
     depreciation and valuation allowances due to impairments on real estate.
     See note 5 to the consolidated financial statements.

(2) Difference from Column B is primarily due to operating gains of investments
    in limited partnerships.

               NATIONWIDE LIFE INSURANCE COMPANY AND SUBSIDIARIES
       (a wholly owned subsidiary of Nationwide Financial Services, Inc.)
              Notes to Unaudited Consolidated Financial Statements
                      Nine Months Ended September 30, 1997

(1)      Organization and Basis of Presentation
         --------------------------------------

         Prior to January 27, 1997, Nationwide Life Insurance Company (NLIC) was
         a wholly owned subsidiary of Nationwide Corporation (Nationwide Corp.).
         On January 27, 1997, Nationwide Corp. contributed the common stock of
         NLIC to Nationwide Financial Services, Inc. (NFS). NFS was formed by
         Nationwide Corp. in November 1996 as a holding company for members of
         the Nationwide Insurance Enterprise that offer or distribute long-term
         savings and retirement products. NLIC and its subsidiaries are
         collectively referred to as "the Company."

         The accompanying unaudited consolidated financial statements of the
         Company have been prepared in accordance with generally accepted
         accounting principles, which differ from statutory accounting practices
         prescribed or permitted by regulatory authorities, for interim
         financial information and with the instructions to Form 10-Q and
         Article 10 of Regulation S-X. Accordingly, they do not include all
         information and footnotes required by generally accepted accounting
         principles for complete financial statements. The financial information
         included herein reflects all adjustments (all of which are normal and
         recurring in nature) which are, in the opinion of management, necessary
         for a fair presentation of financial position and results of
         operations. Operating results for all periods presented are not
         necessarily indicative of the results that may be expected for the full
         year. All significant intercompany balances and transactions have been
         eliminated. The accompanying unaudited consolidated financial
         statements should be read in conjunction with the audited consolidated
         financial statements and related notes for the year ended December 31,
         1996 included in the Company's annual report on Form 10-K.

         Certain items in the prior period consolidated financial statements
         have been reclassified to conform to the current period presentation.

(2)      Dividends and Capital Contributions
         -----------------------------------

         On September 24, 1996, NLIC's Board of Directors declared a dividend to
         Nationwide Corp. consisting of the common stock of certain subsidiaries
         classified as discontinued operations. As of and during the year ended
         December 31, 1996, these previously wholly owned subsidiaries of NLIC
         were classified as discontinued operations since they do not offer or
         distribute long-term savings and retirement products. The dividend was
         paid by NLIC on January 1, 1997.

         On February 24, 1997, NLIC paid a dividend to NFS, which made an
         equivalent dividend to Nationwide Corp., consisting of securities
         having an aggregate fair value of $850.0 million. NLIC recognized a
         gain of $14.4 million on the transfer of securities.

         On March 10, 1997 and March 11, 1997, NFS made cash capital
         contributions to NLIC totaling $836.8 million.

Item 27.  Number of Contract Owners

         The number of Owners of Contracts as of February 28, 1997 was 2726.

Item 28.  Indemnification

         Provision is made in the Company's Amended Code of Regulations and
         expressly authorized by the General Corporation Law of the State of
         Ohio, for indemnification by the Company 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 the Company, 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 the Company pursuant to the foregoing provisions, the
         Company 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.

              (a)   Nationwide Advisory Services, Inc. ("NAS") acts as principal
                    underwriter and general distributor for the NACo Variable

         (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
