- --------------------------------------------------------------------------------

Variable annuities are complex investment products with unique benefits and
advantages that may be particularly useful to many investors in meeting
long-term savings and retirement needs. There are, however, costs and charges
associated with some of these unique benefits - costs and charges that do not
exist or are not present with other investment products. With help from
financial consultants or advisers, investors are encouraged to compare and
contrast the costs and benefits of the variable annuity described in this
prospectus with those of other investment products, including other variable
annuity or variable life insurance products offered by Nationwide Life Insurance
Company and its affiliates. This process will aid in determining whether the
purchase of the contract described in this prospectus is consistent with an
individual's goals, risk tolerance, time horizon, marital status, tax situation,
and other personal characteristics and needs.

THIS PROSPECTUS CONTAINS BASIC INFORMATION YOU SHOULD KNOW ABOUT THE CONTRACTS
BEFORE INVESTING. PLEASE READ THIS PROSPECTUS CAREFULLY AND KEEP IT FOR FUTURE
REFERENCE.

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

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

EXAMPLE

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

The chart reflects expenses of both the variable account and the underlying
mutual funds.

A 7 year CDSC schedule and a variable account charge of 1.30% are assumed.

In addition, the chart reflects the Contract Maintenance Charge, expressed as a
percentage of average account value. Since the average account value is greater
than $1,000, the expense effect of the Contract Maintenance Charge is reduced
accordingly. Deductions for premium taxes are not reflected but may apply.

surrendered in full (see "Contract Maintenance Charge").

Nationwide does not deduct a sales charge from purchase payments upon deposit
into the contract. However, Nationwide may deduct a CDSC if any amount is
withdrawn from the contract. This CDSC reimburses Nationwide for sales expenses.
The amount of the CDSC will not exceed 7% of purchase payments surrendered.

ANNUITY PAYMENTS

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

TAXATION

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

TEN DAY FREE LOOK

Contract owners may return the contract for any reason within ten days of
receipt and Nationwide will refund the contract value or other amounts required
by law (see "Right to Revoke").

CONDENSED FINANCIAL INFORMATION

The value of an accumulation unit is determined on the basis of changes in the
per share value of the underlying mutual funds and the assessment of a variable
account charge which may vary from contract to contract (for more information on
the calculation of accumulation unit values, see "Determining Variable Account
Value - Valuing an

TYPES OF CONTRACTS

The contracts described in this prospectus are classified according to the tax
treatment they are subject to under the Internal Revenue Code. The following is
a general description of the various types of contracts. Eligibility
requirements, tax benefits (if any), limitations, and other features of the
contracts will differ depending on the type of contract.

NON-QUALIFIED CONTRACTS

A Non-Qualified Contract is a contract that does not qualify for certain tax
benefits under the Internal Revenue Code, and which is not an IRA, a Roth IRA, a
SEP IRA, or a Tax Sheltered Annuity.

Upon the death of the owner of a Non-Qualified Contract, mandatory distribution
requirements are imposed to ensure distribution of the entire balance in the
contract a required period.

Non-Qualified Contracts that are owned by natural persons allow for the deferral
of taxation on the income earned in the contract until it is distributed or
deemed to be distributed.

INDIVIDUAL RETIREMENT ANNUITIES (IRAS)

IRAs are contracts that are issued by insurance companies and satisfy the
following requirements:

- -    the contract is not transferable by the owner;

- -    the premiums are not fixed;

- -    the annual premium cannot exceed $2,000 (although rollovers of greater
     amounts from qualified plans, tax-sheltered annuities and other IRAs can be
     received);

- -    certain minimum distribution requirements must be satisfied after the owner
     attains the age of 70 1/2;

- -    the entire interest of the owner in the contract is nonforfeitable; and

- -    after the death of the owner, additional distribution requirements may be
     imposed to ensure distribution of the entire balance in the contract within
     the statutory period of time.

Depending on the circumstance of the owner, all or a portion of the
contributions made to the account may be deducted for federal income tax
purposes.

Failure to make the mandatory distributions can result in an additional penalty
tax of 50% of the excess of the amount required to be distributed over the
amount that was actually distributed.

IRAs may receive rollover contributions from other Individual Retirement
Accounts and Individual Retirement Annuities, from Tax Sheltered Annuities, and
from qualified retirement plans, including 401(k) plans.



                                       10
<PAGE>   11

For further details regarding IRAs, please refer to the disclosure statement
provided when the IRA was established.

SIMPLIFIED EMPLOYEE PENSION IRAs (SEP IRAs)

A SEP IRA is a written plan established by an employer for the benefit of
employees which permits the employer to make contributions to an IRA established
for the benefit of each employee.

An employee may make deductible contributions to a SEP IRA in the same way, and
with the same restrictions and limitations, as for an IRA. In addition, the
employer may make contributions to the SEP IRA, subject to dollar and percentage
limitations imposed by both the Internal Revenue Code and the written plan.

A SEP IRA plan established by an employer must satisfy certain requirements:

- -    minimum participation rules;

- -    top-heavy contribution rules;

- -    nondiscriminatory allocation rules; and

- -    requirements regarding a written allocation formula.

In addition, the plan cannot restrict withdrawals of non-elective contributions,
and must restrict withdrawals of elective contributions before March 15th of the
following year.

ROTH IRAs

Roth IRA contracts are contracts that are issued by insurance companies and
satisfy the following requirements:

- -    the contract is not transferable by the owner;

- -    the premiums are not fixed;

- -    the annual premium cannot exceed $2,000 (although rollovers of greater
     amounts from other Roth IRAs and IRAs can be received);

- -    the entire interest of the owner in the contract is nonforfeitable; and

- -    after the death of the owner, certain distribution requirements may be
     imposed to ensure distribution of the entire balance in the contract within
     the statutory period of time.

A Roth IRA can receive a rollover from an IRA; however, the amount rolled over
from the IRA to the Roth IRA is required to be included in the owner's federal
gross income at the time of the rollover, and will be subject to federal income
tax.

There are income limitations on eligibility to participate in a Roth IRA and
additional income limitations for eligibility to roll over amounts from an IRA
to a Roth IRA. For further details regarding Roth IRAs, please refer to the
disclosure statement provided when the Roth IRA was established.

TAX SHELTERED ANNUITIES

Certain tax-exempt organizations (described in section 501(c)(3) of the Internal
Revenue Code) and public school systems may establish a plan under which annuity
contracts can be purchased for their employees. These annuity contracts are
often referred to as Tax Sheltered Annuities.

Purchase payments made to Tax Sheltered Annuities are excludible from the income
of the employee, up to statutory maximum amounts. These amounts should be set
forth in the plan adopted by the employer.

The owner's interest in the contract is nonforfeitable (except for failure to
pay premiums) and cannot be transferred. Certain minimum distribution
requirements must be satisfied after the owner attains the age of 70 1/2, and
after the death of the owner, additional distribution requirements may be
imposed to ensure distribution of the entire balance in the contract within the
required period of time.

QUALIFIED PLANS

Contracts that are owned by Qualified Plans are not intended to confer tax
benefits on the beneficiaries of the plan; they are used as investment vehicles
for the plan. The income tax consequences to the beneficiary of a



                                       11
<PAGE>   12

Qualified Plan are controlled by the operation of the plan, not by operation of
the assets in which the plan invests.

Beneficiaries of Qualified Plans should contact their employer and/or trustee of
the plan to obtain and review the plan, trust, summary plan description and
other documents for the tax and other consequences of being a participant in a
qualified plan.

INVESTING IN THE CONTRACT

THE VARIABLE ACCOUNT AND UNDERLYING MUTUAL FUNDS

Nationwide VA Separate Account-A is a variable account that invests in the
underlying mutual funds listed in Appendix A. Nationwide established the
variable account on May 6, 1987, pursuant to Ohio law. The variable account was
originally established as the "Financial Horizons VA Separate Account-1."
Subsequently, the name was changed to "Nationwide VA Separate Account-1" by a
Board of Directors resolution. Although the separate account is registered with
the SEC as a unit investment trust pursuant to the Investment Company Act of
1940 ("1940 Act"), the SEC does not supervise the management of Nationwide or
the variable account.

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

The variable account is divided into sub-accounts, each corresponding to a
single underlying mutual fund. Nationwide uses the assets of each sub-account to
buy shares of the underlying mutual funds based on contract owner instructions.
There are two sub-accounts for each underlying mutual fund. One sub-account
contains shares attributable to accumulation units under Non-Qualified
Contracts. The other contains shares attributable to accumulation units under
Individual Retirement Accounts, Roth IRAs, SEP IRAs, Tax Sheltered Annuities,
and Qualified Contracts.

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

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

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

Voting Rights

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

Contract owners with voting interests in an underlying mutual fund will be
notified of issues requiring the shareholders' vote as soon as possible before
the shareholder meeting. Notification will contain proxy materials and a form
with which to give Nationwide voting



                                       12
<PAGE>   13

instructions. Nationwide will vote shares for which no instructions are received
in the same proportion as those that are received.

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

Material Conflicts

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

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

Substitution of Securities

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

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

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

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

THE FIXED ACCOUNT

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

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

The investment income earned by the fixed account will be allocated to the
contracts at varying guaranteed interest rates(s) depending on the following
categories of fixed account allocations:

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

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

- -    Renewal Rate - The rate available for maturing fixed account allocations
     that are



                                       13
<PAGE>   14

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

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

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

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

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

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

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

CHARGES AND DEDUCTIONS

CONTRACT MAINTENANCE CHARGE

On each contract anniversary (and upon a full surrender of the contract),
Nationwide deducts a Contract Maintenance Charge. This charge reimburses
Nationwide for administrative expenses involved in issuing and maintaining the
contract.

The charges are as follows:

  ANNUAL CONTRACT                TYPE OF
   MAINTENANCE                  CONTRACT
    CHARGE                       ISSUED
                    -  Non-Qualified Contracts
       $30.00       -  IRAs
                    -  Tax Sheltered Annuities
                       sold before May 1, 1992
                    -  Qualified Contracts
                       sold before May 1, 1992.(1)
                    -  Tax Sheltered Annuities
       $12.00          sold on or after May 1, 1992.
                       (2)
                    -  Qualified Contracts and
  $0.00 to $30.00      SEP-IRA Contracts sold on or
                       after May 1, 1992.(3)

(1)If an Internal Revenue Code Section 401 plan funded by the contracts was
established before May 1, 1992, all contracts subsequently issued under that
plan will have an annual Contract Maintenance Charge of $30.00.

(2)The Contract Maintenance Charge for these plans may be lowered to reflect
administrative savings.

(3)Nationwide uses internal underwriting guidelines to determine the Contract
Maintenance Charge for these contract types. These guidelines include: the size
of the group, the average participant account balance to be transferred, if any,
and administrative savings. Contract Maintenance Charges for these contracts
will vary in $5.00 increments between $0 and $30.

The deduction of the Contract Maintenance Charge will be taken proportionately
from each sub-account and the fixed account based on the value in each option as
compared to the total contract value.

Nationwide will not increase the Contract Maintenance Charge. Nationwide will
not reduce or eliminate the Contract Maintenance



                                       14
<PAGE>   15

Charge where it would be discriminatory or unlawful.

MORTALITY AND EXPENSE RISK CHARGE

Nationwide deducts Mortality and Expense Risk Charge from the variable account.
This amount is computed on a daily basis, and is equal to an annual rate of
1.25% of the daily net assets of the variable account.

The Mortality Risk Charge is equal to an annual rate of 0.80% of the daily net
assets of the variable account. The Mortality Risk Charge compensates Nationwide
for guaranteeing the annuity purchase rates of the contracts. This guarantee
ensures that the annuity purchase rates will not change regardless of the death
rates of annuity payees or the general population.

The Expense Risk Charge is equal to an annual rate of 0.45% of the daily net
assets of the variable account. The Expense Risk Charge compensates Nationwide
for guaranteeing that charges will not increase regardless of actual expenses.

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

ADMINISTRATION CHARGE

Nationwide deducts an Administration Charge from the variable account. This
amount is computed on a daily basis, and is equal to an annual rate of 0.05% of
the daily net assets of the variable account.

The Administration Charge compensates Nationwide for administrative expenses
related to contract issuance and maintenance.

If this charge is insufficient to cover actual expenses, the loss is borne by
Nationwide.

CONTINGENT DEFERRED SALES CHARGE

No sales charge deduction is made from the purchase payments when amounts are
deposited into the contracts. However, if any part of the contract is
surrendered, Nationwide will deduct a CDSC. The CDSC will not exceed 7% of
purchase payments surrendered.

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

For purposes of calculating the CDSC, surrenders are considered to come first
from the oldest purchase payment made to the contract, then the next oldest
purchase payment, and so forth. Earnings are not subject to the CDSC, but may
not be distributed prior to the distribution of all purchase payments. (For tax
purposes, a surrender is usually treated as a withdrawal of earnings first.)

The CDSC applies as follows:
 Number of Years from Date               CDSC
    of Purchase Payment               Percentage
             0                            7%
             1                            6%
             2                            5%
             3                            4%
             4                            3%
             5                            2%
             6                            1%
             7                            0%

The CDSC is used to cover sales expenses, including commissions (maximum of
6.08% of purchase payments), production of sales material, and other promotional
expenses. If expenses are greater than the CDSC, the shortfall will be made up
from Nationwide's general account, which may indirectly include portions of the
Contract Maintenance Charge and other variable account charges, since Nationwide
may generate a profit from these charges.

All or a portion of any withdrawal may be sujbect to federal income tax.
Contract owners taking withdrawals before age 59 1/2 may be subject to a 10% tax
penalty.

Waiver of Contingent Deferred Sales Charge

Each contract year, the contract owner may withdraw without a CDSC any amount
withdrawn to meet minimum distribution requirements under the Internal Revenue
Code. Starting with the second contract year, a



                                       15
<PAGE>   16

contract owner may withdraw without a CDSC the greater of:
     (a)  10% of all purchase payments; or

     (b)  any amount withdrawn to meet minimum distribution requirements under
          the Internal Revenue Code.

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

In addition, no CDSC will be deducted:

     (1)  upon the annuitization of contracts which have been in force for at
          least two years;

     (2)  upon payment of a death benefit; or

     (3)  from any values which have been held under a contract for at least 7
          years.

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

Nationwide will waive the CDSC on Qualified Contracts, Tax Sheltered Annuities,
and SEP IRAs when:

- -    the plan participant experiences a hardship (as provided in Internal
     Revenue Code Section 403(b) and as defined for purposes of Section 401(k));

- -    the plan participant becomes disabled (within the meaning of Internal
     Revenue Code Section 72(m)(7));

- -    the plan participant reaches age 591/2 and has participated in the contract
     for least 5 years (as determined from the previous contract anniversary);

- -    the plan participant has participated in the contract for at least 15 years
     (as determined from the previous contract anniversary);

- -    the plan participant dies; or

- -    the contract is annuitized after 2 years from the date of contract
     issuance.

Nationwide will waive the CDSC on Non-Qualified Contracts and IRAs other than
SEP IRAs when:

- -    the annuitant dies; or

- -    the contract is annuitized after 2 years from the date of contract
     issuance.

Nationwide may waive or reduce the CDSC for Non-Qualified Contracts when sales
are made without commission or other standard distribution expenses, resulting
in savings of distribution costs.

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

PREMIUM TAXES

Nationwide will charge against the contract value any premium taxes levied by a
state or other government entity. Premium tax rates currently range from 0% to
5.0%. This range is subject to change. The method used to assess premium tax
will be determined by Nationwide at its sole discretion in compliance with state
law.

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

     (1)  the time the contract is surrendered;

     (2)  annuitization; or

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

Premium taxes may be deducted from death benefit proceeds.


                                       16
<PAGE>   17


CONTRACT OWNERSHIP

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

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

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

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

     -    on a Nationwide form;

     -    signed by the contract owner; and

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

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

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

JOINT OWNERSHIP

Joint owners each own an undivided interest in the contract.

Contract owners can name a joint owner at any time before annuitization subject
to the following conditions:

     -    joint owners can only be named for Non-Qualified Contracts;

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

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

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

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

ANNUITANT

The annuitant is the person who will receive annuity payments and upon whose
continuation of life any annuity payment involving life contingencies depends.
This person must be age 78 or younger at the time of contract issuance, unless
Nationwide approves a request for an annuitant of greater age. The annuitant may
be changed before the annuitization date with Nationwide's consent.

BENEFICIARY AND CONTINGENT BENEFICIARY

The beneficiary is the person who is entitled to the death benefit if the
annuitant dies before the annuitization date and there is no joint owner. The
contract owner can name more than one beneficiary. Multiple beneficiaries will
share the death benefit equally, unless otherwise specified.

The contract owner may change the beneficiary or contingent beneficiary during
the annuitant's lifetime by submitting a written request to Nationwide. Once
recorded, the change will be effective as of the date it was signed, whether or
not the annuitant was living at the time it was recorded. The change will not
affect any action taken by Nationwide before the change was recorded.

PRICING

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

Subsequent purchase payments will be priced based on the next available
accumulation unit value after the payment is received. The cumulative total of
all purchase payments under contracts on the life of any one annuitant cannot
exceed $1,000,000 without Nationwide's prior consent.

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

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

Nationwide also will not price purchase payments if:

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

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

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

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

ALLOCATION OF PURCHASE PAYMENTS

Nationwide allocates purchase payments to sub-accounts and/or the fixed account
as instructed by the contract owner. Shares of the underlying mutual funds
allocated to the sub-accounts are purchased at net asset value, then converted
into accumulation units. Contract owners can change allocations or make
exchanges among the sub-accounts and the fixed account. However, no change may
be made that would result in an amount less than 1% of the purchase payments
being allocated to any sub-account. Certain transactions may be subject to
conditions imposed by the underlying mutual funds, as well as those set forth in
the contract.

DETERMINING THE CONTRACT VALUE

The contract value is the sum of:

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

     2)   amounts allocated to the fixed account.

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

Determining Variable Account Value - Valuing an Accumulation Unit

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



                                       18
<PAGE>   19

units. Accumulation unit values (for each sub-account) are determined by
calculating the net investment factor for the underlying mutual funds for the
current valuation period and multiplying that result with the accumulation unit
values determined on the previous valuation period.

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

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

     (a)  is:

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

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

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

     (c)  is a factor representing the daily variable account charges. The
          factor is equal to an annual rate of 1.30% of the daily net assets of
          the variable account.

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

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

Determining Fixed Account Value

Nationwide determines the value of the fixed account by:

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

     2)   adding any interest earned on the amounts allocated.

TRANSFERS PRIOR TO ANNUITIZATION

Transfers from the Fixed Account to the Variable Account

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

Contract owners who use Dollar Cost Averaging may transfer from the fixed
account to the variable account under the terms of that program (see "Dollar
Cost Averaging").

Transfers to the Fixed Account

Variable account allocations may be transferred to the fixed account at any
time. Normally, Nationwide will not restrict transfers from the variable account
to the fixed account; however, Nationwide may establish a maximum transfer limit
from the variable account to the fixed account. Except as noted below, under no
circumstances will the transfer limit be less than



                                       19
<PAGE>   20

10% of the current value of the variable account, less any transfers made in the
12 months preceding the date the transfer is requested, but not including
transfers made prior to the imposition of the transfer limit. However, where
permitted by state law, Nationwide reserves the right to refuse transfers or
purchase payments to the fixed account when the fixed account value is greater
than or equal to 30% of the contract value at the time the purchase payment is
made or the transfer is requested.

Transfers Among the Sub-Accounts

Allocations may be transferred among the sub-accounts once per valuation period.

TRANSFERS AFTER ANNUITIZATION

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

TRANSFER REQUESTS

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

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

Interest Rate Guarantee Period

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

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

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

Market Timing Firms

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

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

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

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

- -    submitted on behalf of individual contract owners who have executed
     pre-authorized



                                       20
<PAGE>   21

     exchange forms which are submitted by market timing firms (or other third
     parties) on behalf of more than one contract owner at the same time.

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

RIGHT TO REVOKE

Contract owners have a ten day "free look" to examine the contract. The contract
may be returned to Nationwide's home office for any reason within ten days of
receipt and Nationwide will refund the contract value or another amount required
by law. The refunded contract value will reflect the deduction of any contract
charges, unless otherwise required by law. All IRA, SEP IRA and Roth IRA refunds
will be a return of purchase payments. State and/or federal law may provide
additional free look privileges.

Liability of the variable account under this provision is limited to the
contract value in each sub-account on the date of revocation. Any additional
amounts refunded to the contract owner will be paid by Nationwide.

SURRENDER (REDEMPTION)

Contract owners may surrender some or all of their contract value before the
earlier of the annuitization date or the annuitant's death. Surrender requests
must be in writing and Nationwide may require additional information. When
taking a full surrender, the contract must accompany the written request.
Nationwide may require a signature guarantee.

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

PARTIAL SURRENDERS (PARTIAL REDEMPTIONS)

Nationwide will surrender accumulation units from the sub-accounts and an amount
from the fixed account. The amount withdrawn from each investment option will be
in proportion to the value in each option at the time of the surrender request.

A CDSC may apply. The contract owner may direct Nationwide to deduct the CDSC
from either:

     a)   the amount requested; or

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

If the contract owner does not make a specific election, any applicable CDSC
will be taken from the contract value remaining after the contract owner has
received the amount requested.

FULL SURRENDERS (FULL REDEMPTIONS)

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

SURRENDERS UNDER A TEXAS OPTIONAL RETIREMENT PROGRAM

Redemption restrictions apply to contracts issued under the Texas Optional
Retirement Program.

The Texas Attorney General has ruled that participants in contracts issued under
the Texas Optional Retirement Program may only take withdrawals if:

- -    the participant dies;

- -    the participant retires;

- -    the participant terminates employment due to total disability; or

- -    the participant that works in a Texas public institution of higher
     education terminates employment.

Due to the restrictions described above, a participant under this plan will not
be able to withdraw cash values from the contract unless



                                       21
<PAGE>   22

one of the applicable conditions is met. However, contract value may be
transferred to other carriers, subject to any CDSC.

Nationwide issues this contract to participants in the Texas Optional Retirement
Program in reliance upon and in compliance with Rule 6c-7 of the Investment
Company Act of 1940.

SURRENDERS UNDER A QUALIFIED PLAN OR TAX SHELTERED ANNUITY

Contract owners of a Qualified Plan or Tax Sheltered Annuity may surrender part
or all of their contract value before the earlier of the annuitization date or
the annuitant's death, except as provided below:

A.   Contract value attributable to contributions made under a qualified cash or
     deferred arrangement (within the meaning of Internal Revenue Code Section
     402(g)(3)(A)), a salary reduction agreement (within the meaning of Internal
     Revenue Code Section 402(g)(3)(C)), or transfers from a Custodial Account
     (described in Section 403(b)(7) of the Internal Revenue Code), may be
     surrendered only:

     1.   when the contract owner reaches age 59 1/2, separates from service,
          dies, or becomes disabled (within the meaning of Internal Revenue Code
          Section 72(m)(7)); or

     2.   in the case of hardship (as defined for purposes of Internal Revenue
          Code Section 401(k)), provided that any such hardship surrender may
          NOT include any income earned on salary reduction contributions.

B.   The surrender limitations described in Section A also apply to:

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

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

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

C.   Any distribution other than the above, including a ten day free look
     cancellation of the contract (when available) may result in taxes,
     penalties, and/or retroactive disqualification of a Qualified Contract or
     Tax Sheltered Annuity.

In order to prevent disqualification of a Tax Sheltered Annuity after a ten day
free look cancellation, Nationwide will transfer the proceeds to another Tax
Sheltered Annuity upon proper direction by the contract owner.

These provisions explain Nationwide's understanding of current withdrawal
restrictions. These restrictions may change.

Distributions pursuant to Qualified Domestic Relations Orders will not violate
the restrictions stated above.

Plan terms and the Internal Revenue Code may modify surrender provisions when
the contract is issued to fund a Qualified Plan.

LOAN PRIVILEGE

The loan privilege is ONLY available to owners of Qualified Contracts and Tax
Sheltered Annuities. These contract owners can take loans from the contract
value beginning 30 days after the contract is issued up to the annuitization
date. Loans are subject to the terms of the contract, the plan, and the Internal
Revenue Code. Nationwide may modify the terms of a loan to comply with changes
in applicable law.

MINIMUM  & MAXIMUM LOAN AMOUNTS

Contract owners may borrow a minimum of $1,000, unless Nationwide is required by
law to allow a lesser minimum amount. Each loan must individually satisfy the
contract minimum amount.



                                       22
<PAGE>   23

Nationwide will calculate the maximum nontaxable loan amount based upon
information provided by the participant or the employer. Loans may be taxable if
a participant has additional loans from other plans. The total of all
outstanding loans must not exceed the following limits:

                 CONTRACT     MAXIMUM OUTSTANDING LOAN
                 VALUES       BALANCE ALLOWED

NON-ERISA PLANS  up to        up to 80% of contract
                 $20,000      value (not more than
                              $10,000)

                 $20,000      up to 50% of contract
                 and over     value (not more than
                              $50,000*)

ERISA PLANS      All          up to 50% of contract
                              value (not more than
                              $50,000*)

*The $50,000 limits will be reduced by the highest outstanding balance owed
during the previous 12 months.

For salary reduction Tax Sheltered Annuities, loans may be secured only by the
contract value.

LOAN PROCESSING FEE

Nationwide may charge a loan processing fee at the time each new loan is
processed. If assessed, this fee compensates Nationwide for expenses related to
administering and processing loans.

The fee is taken from the sub-accounts and the fixed account in proportion to
the contract value at the time the loan is processed.

HOW LOAN REQUESTS ARE PROCESSED

All loans are made from the collateral fixed account. Nationwide transfers
accumulation units in proportion to the assets in each sub-account to the
collateral fixed account until the requested amount is reached. If there are not
enough accumulation units available in the contract to reach the requested loan
amount, Nationwide next transfers contract value from the fixed account. No CDSC
will be deducted on transfers related to loan processing.

INTEREST

The outstanding loan balance in the collateral fixed account is credited with
interest until the loan is repaid in full. The credited interest rate will be
2.25% less than the loan interest rate fixed by Nationwide. The credited
interest rate is guaranteed never to fall below 3.0%.

Specific loan terms are disclosed at the time of loan application or issuance.

LOAN REPAYMENT

Loans must be repaid in five years. However, if the loan is used to purchase the
contract owner's principal residence, the contract owner has 15 years to repay
the loan.

Contract owners must identify loan repayments as loan repayments or they will be
treated as purchase payments and will not reduce the outstanding loan. Payments
must be substantially level and made at least quarterly.

Loan repayments will consist of principal and interest in amounts set forth in
the loan agreement. Repayments are allocated to the sub-accounts in accordance
with the contract, unless Nationwide and the contract owner have agreed to amend
the contract at a later date on a case by case basis.

DISTRIBUTIONS & ANNUITY PAYMENTS

Distributions made from the contract while a loan is outstanding will be reduced
by the amount of the outstanding loan plus accrued interest if:

     -    the contract is surrendered;

     -    the contract owner/annuitant dies;

     -    the contract owner who is not the annuitant dies prior to
          annuitization; or

     -    annuity payments begin.

TRANSFERRING THE CONTRACT

Nationwide reserves the right to restrict any transfer of the contract while the
loan is outstanding.

GRACE PERIOD & LOAN DEFAULT

If a loan payment is not made when due, interest will continue to accrue. A
grace period may be available (please refer to the terms of the loan agreement).
If a loan payment is not made by the end of the applicable grace period, the
entire



                                       23
<PAGE>   24

loan will be treated as a deemed distribution and will be taxable to the
borrower. This deemed distribution may also be subject to an early withdrawal
tax penalty by the Internal Revenue Service.



After default, interest will continue to accrue on the loan. Defaulted amounts,
plus interest, are deducted from the contract value when the participant is
eligible for a distribution of at least that amount. Additional loans are not
available while a previous loan is in default.

ASSIGNMENT

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

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

IRAs, Roth IRAs, SEP IRAs, Qualified Contracts and Tax Sheltered Annuities may
not be assigned, pledged or otherwise transferred except where allowed by law.

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

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

Assignment of the entire contract value may cause the portion of the contract
value exceeding the total investment in the contract and previously taxed
amounts to be included in gross income for federal income tax purposes each year
that the assignment is in effect.

CONTRACT OWNER SERVICES

ASSET REBALANCING

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

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

Asset rebalancing may be subject to employer limitations or restrictions for
contracts issued to a Qualified Plan or Tax Sheltered Annuity plan. Contract
owners should consult a financial adviser to discuss the use of asset
rebalancing.

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

DOLLAR COST AVERAGING

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

Contract owners direct Nationwide to automatically transfer specified amounts
from the fixed account, the NSAT Government Bond Fund, and the NSAT Money Market
Fund to any other underlying mutual fund. Transfers



                                       24
<PAGE>   25

from the fixed account must be equal to or less than 1/30th of the fixed account
value when the Dollar Cost Averaging program is requested.

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

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

SYSTEMATIC WITHDRAWALS

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

The withdrawals will be taken from the sub-accounts and the fixed account
proportionately unless Nationwide is instructed otherwise.

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

A CDSC may apply to amounts taken through systematic withdrawals.

If a CDSC applies, the maximum amount that can be withdrawn annually without a
CDSC is the greatest of:

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

     2)   an amount withdrawn to meet minimum distribution requirements under
          the Internal Revenue Code.

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

Nationwide reserves the right to stop Nationwide reserves the right to stop
establishing new systematic withdrawal programs. Nationwide also reserves the
right to assess a processing fee for this service. Systematic withdrawals are
not available before the end of the ten-day free look period (see "Right to
Revoke").

ANNUITY COMMENCEMENT DATE

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

ANNUITIZING THE CONTRACT

ANNUITIZATION DATE

The annuitization date is the date that annuity payments begin. It will be the
first day of a calendar month unless otherwise agreed, and must be at least 2
years after the contract is issued. If the contract is issued to fund a
Qualified Plan or Tax Sheltered Annuity plan, annuitization may occur during the
first 2 years subject to Nationwide's approval.

ANNUITIZATION

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

     1)   an annuity payment option; and

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

Nationwide guarantees that each payment under a fixed payment annuity will be
the same throughout annuitization. Under a variable payment annuity, the amount
of each payment will vary with the performance of the



                                       25
<PAGE>   26

underlying mutual funds chosen by the contract owner.

FIXED PAYMENT ANNUITY

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

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

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

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

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

VARIABLE PAYMENT ANNUITY

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

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

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

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

The dollar amount of the first payment is converted into a set number of annuity
units that will represent each monthly payment. This is done by dividing the
dollar amount of the first payment by the value of an annuity unit as of the
annuitization date. This number of annuity units remains fixed during
annuitization.

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

Assumed Investment Rate

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

Value of an Annuity Unit

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

Exchanges among Underlying Mutual Funds

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

FREQUENCY AND AMOUNT OF ANNUITY PAYMENTS

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



                                       26
<PAGE>   27

     -    the amount to be distributed is less than $500, in which case
          Nationwide may make one lump sum payment of the contract value; or

     -    an annuity payment would be less than $20, in which case Nationwide
          can change the frequency of payments to intervals that will result in
          payments of at least $20. Payments will be made at least annually.

ANNUITY PAYMENT OPTIONS

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

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

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

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

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

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

No distribution for Non-Qualified Contracts will be made until an annuity
payment option has been elected. IRAs, SEP IRAs, and Tax Sheltered Annuities are
subject to the "minimum distribution" requirements set forth in the plan,
contract, and the Internal Revenue Code.

DEATH BENEFITS

DEATH OF CONTRACT OWNER - NON-QUALIFIED CONTRACTS

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

Distributions under Non-Qualified Contracts will be made pursuant to the
"Required Distributions for Non-Qualified Contracts" provision.

DEATH OF ANNUITANT - NON-QUALIFIED CONTRACTS

If the annuitant who is not a contract owner dies before the annuitization date,
a death benefit is payable to the beneficiary unless a contingent annuitant is
named. If a contingent annuitant is named, the contingent annuitant becomes the
annuitant and no death benefit is payable.

The beneficiary may elect to receive the death benefit:

     1)   in a lump sum;

     2)   as an annuity; or

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

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



                                       27
<PAGE>   28

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

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

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

DEATH OF CONTRACT OWNER/ANNUITANT

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

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

DEATH BENEFIT PAYMENT

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

     1)   proper proof of the annuitant's death;

     2)   an election specifying the distribution method; and

     3)   any state required form(s).

For contracts issued BEFORE May 1, 1991, the death benefit will be the greater
of:

     1)   the contract value; or

     2)   the total of all purchase payments, less any amounts surrendered.

For contracts issued ON OR AFTER May 1, 1991 UP TO the later of May 1, 1998 or a
date insurance authorities approve applicable contract modifications, if the
annuitant dies before his or her 75th birthday, the death benefit will be the
greater of:

     1)   the contract value; or

     2)   the total of all purchase payments, increased at an annual rate of 5%
          simple interest for each year the purchase payment is in force, less
          any amounts previously surrendered.

For contracts issued ON OR AFTER the later of May 1, 1998 or the date state
insurance authorities approve applicable contract modifications, the death
benefit will be the greater of:

     1)   the contract value; or

     2)   the total of all purchase payments, increased at an annual rate of 5%
          simple interest for each year the purchase payment is in force, less
          an adjustment for amounts previously surrendered.

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

Some states prohibit the use of the death benefit described in this provision
(e.g. North Carolina). For contracts issued in NORTH CAROLINA BEFORE May 1,
1998, the death benefit will be the greater of:

     1)   the contract value; or

     2)   the total of all purchase payments, less any amounts surrendered.

For contracts issued in NORTH CAROLINA ON OR AFTER May 1, 1998, the death
benefit will be the greater of:

     1)   the contract value; or

     2)   the total of all purchase payments, less an adjustment for amounts
          surrendered.

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

For all contracts, if the annuitant dies on or after his or her 75th birthday,
the death benefit will be the contract value.

REQUIRED DISTRIBUTIONS

REQUIRED DISTRIBUTIONS FOR NON-QUALIFIED CONTRACTS

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

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

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

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

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

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

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

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

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

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

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

REQUIRED DISTRIBUTIONS FOR QUALIFIED PLANS AND TAX SHELTERED ANNUITIES

Distributions from Qualified Plans and Tax Sheltered Annuities will be made
according to the Minimum Distribution and Incidental Benefit ("MDIB") provisions
of Section 401(a)(9) of the Internal Revenue Code. Distributions will be made to
the annuitant according to the selected annuity payment option over a period not
longer than

     a)   the life of the annuitant or the joint lives of the annuitant and the
          annuitant's designated beneficiary; or

     b)   a period not longer than the life expectancy of the annuitant or the
          joint life expectancies of the annuitant and the annuitant's
          designated beneficiary.

Required distributions do not have to be withdrawn from this contract if they
are being withdrawn from another Tax Sheltered Annuity of the annuitant.

If the annuitant's entire interest in a Qualified Plan or Tax Sheltered Annuity
will be distributed in equal or substantially equal payments over a period
described in a) or b), the payments will begin on the required beginning date.
The required beginning date is the later of:



                                       29
<PAGE>   30

     a)   April 1 of the calendar year following the calendar year in which the
          annuitant reaches age 70 1/2; or

     b)   the annuitant's retirement date.

Provision b) does not apply to any employee who is a 5% owner (as defined in
Section 416 of the Internal Revenue Code) with respect to the plan year ending
in the calendar year when the employee attains the age of 70 1/2.

Distribution commencing on the required distribution date must satisfy minimum
distribution and incidental benefit provisions set forth in the Internal Revenue
Code. Those provisions require that distributions cannot be less than the amount
determined by dividing the annuitant's interest in the Tax Sheltered Annuity
determined by the end of the previous calendar year by:

     a)   the annuitant's life expectancy; or, if applicable,

     b)   the joint and survivor life expectancy of the annuitant and the
          annuitant's beneficiary.

The life expectancies and joint life expectancies are determined by reference to
Treasury Regulation 1.72-9.

If the annuitant dies before distributions begin, the interest in the Qualified
Contract or Tax Sheltered Annuity must be distributed by December 31 of the
calendar year in which the fifth anniversary of the annuitant's death occurs
unless:

     a)   the annuitant names his or her surviving spouse as the beneficiary and
          the spouse chooses to receive distribution of the contract in
          substantially equal payments over his or her life (or a period not
          longer than his or her life expectancy) and beginning no later than
          December 31 of the year in which the annuitant would have attained age
          70 1/2; or

     b)   the annuitant names a beneficiary other than his or her surviving
          spouse and the beneficiary elects to receive distribution of the
          contract in substantially equal payments over his or her life (or a
          period not longer than his or her life expectancy) beginning no later
          than December 31 of the year following the year in which the annuitant
          dies.

If the annuitant dies after distributions have begun, distributions must
continue at least as rapidly as under the schedule used before the annuitant's
death.

If distribution requirements are not met, a penalty tax of 50% is levied on the
difference between the amount that should have been distributed for that year
and the amount that actually was distributed for that year.

REQUIRED DISTRIBUTIONS FOR IRAs AND SEP IRAs

Distributions from an IRA or SEP IRA must begin no later than April 1 of the
calendar year following the calendar year in which the contract owner reaches
age 70 1/2. Distribution may be paid in a lump sum or in substantially equal
payments over:

     a)   the contract owner's life or the lives of the contract owner and his
          or her spouse or designated beneficiary; or

     b)   a period not longer than the life expectancy of the contract owner or
          the joint life expectancy of the contract owner and the contract
          owner's designated beneficiary.

If the contract owner dies before distributions begin, the interest in the IRA
or SEP IRA must be distributed by December 31 of the calendar year in which the
fifth anniversary of the contract owner's death occurs, unless:

     a)   the contract owner names his or her surviving spouse as the
          beneficiary and such spouse chooses to:

          1)   treat the contract as an IRA or SEP IRA established for his or
               her benefit; or

          2)   receive distribution of the contract in substantially equal
               payments over his



                                       30
<PAGE>   31

               or her life (or a period not longer than his or her life
               expectancy) and beginning no later than December 31 of the year
               in which the contract owner would have reached age 70 1/2; or

     b)   the contract owner names a beneficiary other than his or her surviving
          spouse and such beneficiary elects to receive a distribution of the
          contract in substantially equal payments over his or her life (or a
          period not longer than his or her life expectancy) beginning no later
          than December 31 of the year following the year of the contract
          owner's death.

Required distributions do not have to be withdrawn from this contract if they
are being withdrawn from another IRA or SEP IRA of the contract owner.

If the contract owner dies after distributions have begun, distributions must
continue at least as rapidly as under the schedule being used before the
contract owner's death. However, a surviving spouse who is the beneficiary under
the annuity payment option may treat the contract as his or her own, in the same
manner as is described in section (a)(1) of this provision.

If distribution requirements are not met, a penalty tax of 50% is levied on the
difference between the amount that should have been distributed for that year
and the amount that actually was distributed for that year.

A portion of each distribution will be included in the recipient's gross income
and taxed at ordinary income tax rates. The portion of a distribution which is
taxable is based on the ratio between the amount by which non-deductible
purchase payments exceed prior nontaxable distributions and total account
balances at the time of the distribution. The owner of an IRA or SEP IRA must
annually report the amount of non-deductible purchase payments, the amount of
any distribution, the amount by which non-deductible purchase payments for all
years exceed nontaxable distributions for all years, and the total balance of
all Individual Retirement Annuities.

IRA and SEP IRA distributions will not receive the favorable tax treatment of a
lump sum distribution from a Qualified Plan. If the contract owner dies before
the entire interest in the contract has been distributed, the balance will also
be included in his or her gross estate.

REQUIRED DISTRIBUTIONS FOR ROTH IRAs

The rules for Roth IRAs do not require distributions to begin during the
contract owner's lifetime.

When the contract owner dies, the interest in the Roth IRA must be distributed
by December 31 of the calendar year in which the fifth anniversary of his or her
death occurs, unless:

     a)   the contract owner names his or her surviving spouse as the
          beneficiary and the spouse chooses to:

          1)   treat the contract as a Roth IRA established for his or her
               benefit; or

          2)   receive distribution of the contract in substantially equal
               payments over his or her life (or a period not longer than his or
               her life expectancy) and beginning no later than December 31 of
               the year following the year in which the contract owner would
               have reached age 70 1/2; or

     b)   the contract owner names a beneficiary other than his or her surviving
          spouse and the beneficiary chooses to receive distribution of the
          contract in substantially equal payments over his or her life (or a
          period not longer than his or her life expectancy) beginning no later
          than December 31 of the year following the year in which the contract
          owner dies.

Distributions from Roth IRAs may be either taxable or nontaxable, depending upon
whether they are "qualified distributions" or "non-qualified distributions" (see
"Federal Tax Considerations").


                                       31

FEDERAL TAX CONSIDERATIONS

FEDERAL INCOME TAXES

The tax consequences of purchasing a contract described in this prospectus will
depend on:

- - the type of contract purchased;

- - the purposes for which the
contract is purchased; and

- - the personal circumstances of individual investors
having interests in the contracts.

See "Synopsis of the Contracts" for a brief description of the various types of
contracts and the different purposes for which the contracts may be purchased.

Existing tax rules are subject to change, and may affect individuals differently
depending on their situation. Nationwide does not guarantee the tax status of
any contracts or any transactions involving the contracts.

If the contract is purchased as an investment of certain retirement plans (such
as qualified retirement plans, IRAs and custodial accounts as described in
Sections 401, 408(a), and 403(b)(7) of the Internal Revenue Code), tax
advantages enjoyed by the contract owner and/or annuitant may relate to
participation in the plan rather than ownership of the annuity contract. Such
plans are permitted to purchase investments other than annuities and retain
tax-deferred status.

The following is a brief summary of some of the federal income tax
considerations related to the contracts. In addition to the federal income tax,
distributions from annuity contracts may be subject to state and local income
taxes. The tax rules across all states and localities are not uniform and
therefore will not be discussed in this prospectus. Tax rules that may apply to
contracts issued in U.S. territories such as Puerto Rico and Guam are also not
discussed. Nothing in this prospectus should be considered to be tax advice.
Contract owners and prospective contract owners are encouraged to consult a
financial consultant, tax advisor or legal counsel to discuss the taxation and
use of the contracts.

The Internal Revenue Code sets forth different income tax rules for the
following types of annuity contracts:

- -    IRAs;

- -    SEP IRAs;

- -    Roth IRAs;

- -    Tax Sheltered Annuities; and

- -    "Non-Qualified Annuities."

IRAs and SEP IRAs

Distributions from IRAs and SEP IRAs are generally taxed when received. If any
of the amount contributed to the IRA was nondeductible for federal income tax
purposes, then a portion of each distribution is excludable from income.

If distributions of income from an IRA are made prior to the date that the owner
attains the age of 59 1/2 years, the income is subject to both the regular
income tax and an additional penalty tax of 10%. The penalty tax can be avoided
if the distribution is:

- -    made to a beneficiary on or after the death of the owner;

- -    attributable to the owner becoming disabled (as defined in the Internal
     Revenue Code;

- -    part of a series of substantially equal periodic payments made not less
     frequently than annually made for the life (or life expectancy) of the
     owner, or the joint lives (or joint life expectancies) of the owner and his
     or her designated beneficiary;

- -    used for qualified higher education expenses; or

- -    used for expenses attributable to the purchase of a home for a qualified
     first-time buyer.

Roth IRAs

Distributions of earnings from Roth IRAs are taxable or non-taxable depending
upon whether



                                       32
<PAGE>   33

they are "qualified distributions" or "non-qualified distributions." A
"qualified distribution" is one that satisfies the five-year rule and meets one
of the following requirements:

- -    it is made on or after the date on which the contract owner attains age 59
     1/2;

- -    it is made to a beneficiary (or the contract owner's estate) on or after
     the death of the contract owner;

- -    it is attributable to the contract owner's disability; or

- -    it is used for expenses attributable to the purchase of a home for a
     qualified first-time buyer.

The five year rule generally is satisfied if the distribution is not made within
the five taxable year period beginning with the first taxable year in which a
contribution is made to any Roth IRA established for the owner.

A qualified distribution is not included in gross income for federal income tax
purposes.

A non-qualified distribution is not includible in gross income to the extent
that the distribution, when added to all previous distributions, does not exceed
that total amount of contributions made to the Roth IRA. Any non-qualified
distribution in excess of the aggregate amount of contributions will be included
in the contract owner's gross income in the year that is distributed to the
contract owner.

Special rules apply for Roth IRAs that have proceeds received from an IRA prior
to January 1, 1999 if the owner elected the special 4-year income averaging
provisions that were in effect for 1998.

If non-qualified distributions of income from a Roth IRA are made prior to the
date that the owner attains the age of 59 1/2 years, the income is subject to
both the regular income tax and an additional penalty tax of 10%. The penalty
tax can be avoided if the distribution is:

- -    made to a beneficiary on or after the death of the owner;

- -    attributable to the owner becoming disabled (as defined in the Internal
     Revenue Code);

- -    part of a series of substantially equal periodic payments made not less
     frequently than annually made for the life (or life expectancy) of the
     owner, or the joint lives (or joint life expectancies) of the owner and his
     or her designated beneficiary;

- -    for qualified higher education expenses; or

- -    used for expenses attributable to the purchase of a home for a qualified
     first-time buyer.

If the contract owner dies before the contract is completely distributed, the
balance may be included in the contract owner's gross estate for tax purposes.

Tax Sheltered Annuities

Distributions from Tax Sheltered Annuities are generally taxed when received. A
portion of each distribution is excludable from income based on a formula
established pursuant to the Internal Revenue Code. The formula excludes from
income the amount invested in the contract divided by the number of anticipated
payments until the full investment in the contract is recovered. Thereafter all
distributions are fully taxable.

If a distribution of income is made from a Tax Sheltered Annuity prior to the
date that the owner attains the age of 59 1/2 years, the income is subject to
both the regular income tax and an additional penalty tax of 10%. The penalty
tax can be avoided if the distribution is:

- -    made to a beneficiary on or after the death of the owner;

- -    attributable to the owner becoming disabled as defined in the Internal
     Revenue Code;

- -    part of a series of substantially equal periodic payments made not less
     frequently than annually made for the life (or life expectancy) of the
     owner, or the joint lives (or joint life expectancies) of the owner and his
     or her designated beneficiary;

                                       33
<PAGE>   34

- -    used for qualified higher education expenses;

- -    used for expenses attributable to the purchase of a home for a qualified
     first-time buyer; or

- -    made to the owner after separation from service with his or her employer
     after age 55.

Non-Qualified Contracts - Natural Persons as Contract Owners

Generally, the income earned inside a Non-Qualified Contract that is owned by a
natural person is not taxable until it is distributed from the contract.

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

With respect to annuity distributions on or after the annuitization date, a
portion of each annuity payment is excludable from taxable income. The amount
excludable is based on the ratio between the contract owner's investment in the
contract and the expected return on the contract. Once the entire investment in
the contract is recovered, all distributions are fully includable in income. The
maximum amount excludable from income is the investment in the contract. If the
annuitant dies before the entire investment in the contract has been excluded
from income, and as a result of the annuitant's death no more payments are due
under the contract, then the unrecovered investment in the contract may be
deducted on his or her final tax return.

In determining the taxable amount of a distribution, all annuity contracts
issued after October 21, 1988 by the same company to the same contract owner
during the same calendar year will be treated as one annuity contract.

A special rule applies to distributions from contracts that have investments
that were made prior to August 14, 1982. For those contracts, distributions that
are made prior to the annuitization date are treated first as a recovery of the
investment in the contract as of that date. A distribution in excess of the
amount of the investment in the contract as of August 14, 1982, will be treated
as taxable income.

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

- -    the result of a contract owner's death;

- -    the result of a contract owner's disability, as defined in the Internal
     Revenue Code;

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

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

Non-Qualified Contracts - Non-Natural Persons as Contract Owners

The previous discussion related to the taxation of Non-Qualified Contracts owned
by individuals. Different rules (the so-called "non-natural persons" rules)
apply if the contract owner is not a natural person.

Generally, contracts owned by corporations, partnerships, trusts, and similar
entities are not treated as annuity contracts under the Internal Revenue Code.
Therefore, income earned under a Non-Qualified Contract that is owned by a
non-natural person is taxed as ordinary income during the taxable year that it
is earned.



                                       34
<PAGE>   35

Taxation is not deferred, even if the income is not distributed out of the
contract. The income is taxable as ordinary income, not capital gain.

The non-natural persons rules do not apply to all entity-owned contracts. A
contract that is owned by a non-natural person as an agent of an individual is
treated as owned by the individual. This would cause the contract to be treated
as an annuity under the Internal Revenue Code, allowing tax deferral. However,
this exception does not apply when the non-natural person is an employer that
holds the contract under a non-qualified deferred compensation arrangement for
one or more employees.

The non-natural persons rules also do not apply to contracts that are:

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

- -    issued in connection with certain qualified retirement plans and individual
     retirement plans; or

- -    purchased by an employer upon the termination of certain qualified
     retirement plans.

WITHHOLDING

Pre-death distributions from the contracts are subject to federal income tax.
Nationwide will withhold the tax from the distributions unless the contract
owner requests otherwise. If the distribution is from a Tax Sheltered Annuity,
it will be subject to mandatory 20% withholding that cannot be waived, unless:

- -    the distribution is made directly to another Tax Sheltered Annuity or IRA;
     or

- -    the distribution satisfies the minimum distribution requirements imposed by
     the Internal Revenue Code.

In addition, contract owners may not waive withholding if the distribution is
subject to mandatory back-up withholding (if no taxpayer identification number
is given or if the Internal Revenue Service notifies Nationwide that mandatory
back-up withholding is required). Mandatory back-up withholding rates are 31% of
income that is distributed.

NON-RESIDENT ALIENS

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

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

     2)   provide Nationwide with an individual taxpayer identification number.

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

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

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

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

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

FEDERAL ESTATE, GIFT, AND GENERATION SKIPPING TRANSFER TAXES

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

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

     -    a distribution to someone other than a contract owner.



                                       35
<PAGE>   36

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

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

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

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

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

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

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

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

CHARGE FOR TAX

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

DIVERSIFICATION

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

- -    the failure to diversify was accidental;

- -    the failure is corrected; and

- -    a fine is paid to the Internal Revenue Service.

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

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

TAX CHANGES

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

STATEMENTS AND REPORTS

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

These mailings will contain:

     -    statements showing the contract's quarterly activity;

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



                                       36
<PAGE>   37

          recurring transactions will appear in the contract's quarterly
          statements;

     -    semi-annual reports as of June 30 containing financial statements for
          the variable account; and

     -    annual reports as of December 31 containing financial statements for
          the variable account.

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

LEGAL PROCEEDINGS

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

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

On October 29, 1998, Nationwide was named in a lawsuit filed in Ohio state court
related to the sale of deferred annuity products for use as investments in
tax-deferred contributory retirement plans (Mercedes Castillo v. Nationwide
Financial Services, Inc., Nationwide Life Insurance Company and Nationwide Life
and Annuity Insurance Company). On May 3, 1999, the complaint was amended to,
among other things, add Marcus Shore as a second plaintiff. The amended
complaint is brought as a class action on behalf of all persons who purchased
individual deferred annuity contracts or participated in group annuity contracts
sold by Nationwide and the other named Nationwide affiliates which were used to
fund certain tax-deferred retirement plans. The amended complaint seeks
unspecified compensatory and punitive damages. No class has been certified. On
June 11, 1999, Nationwide and the other named defendants filed a motion to
dismiss the amended complaint. On March 8, 2000, the Court denied the motion to
dismiss filed by Nationwide and the other named defendants. Nationwide intends
to defend this lawsuit vigorously.

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

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

ADVERTISING AND SUB-ACCOUNT PERFORMANCE SUMMARY

ADVERTISING

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

Nationwide may advertise the performance of a sub-account in relation to the
performance of other variable annuity sub-accounts, underlying mutual fund
options with similar or different objectives, or the investment industry as a
whole. Other investments to which the sub-accounts may be compared include, but
are not limited to:

     -    precious metals;
     -    real estate;



                                       37
<PAGE>   38

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

Market Indexes

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

     -    S&P 500;
     -    Shearson/Lehman Intermediate Government/Corporate Bond Index;
     -    Shearson/Lehman Long-Term Government/Corporate Bond Index;
     -    Donoghue Money Fund Average;
     -    U.S. Treasury Note Index;
     -    Bank Rate Monitor National Index of 2 1/2 Year CD Rates; and
     -    Dow Jones Industrial Average.

Tracking & Rating Services; Publications

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

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

          >    Time;
          >    Newsweek;
          >    National Underwriter; and
          >    News and World Report;
     -    LIMRA;
     -    Value;
     -    Best's Agent Guide;
     -    Western Annuity Guide;
     -    Comparative Annuity Reports;
     -    Wall Street Journal;
     -    Barron's;
     -    Investor's Daily;
     -    Standard & Poor's Outlook; and
     -    Variable Annuity Research & Data Service (The VARDS Report).

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

Financial Rating Services

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

Some Nationwide advertisements and endorsements may include lists of
organizations, individuals or other parties that recommend Nationwide or the
contract. Furthermore, Nationwide may occasionally advertise comparisons of
currently taxable and tax deferred investment programs, based on selected tax
brackets, or discussions of alternative investment vehicles and general economic
conditions.

corporation in 1987. It is a diversified, open-end management investment company
which offers its shares only as investment vehicles for variable annuity and
variable life insurance products of insurance companies. American Century

     intends to invest approximately (i) 20% of the Fund's assets in securities
     of the United States


                                       40
<PAGE>   41

     government and its agencies and instrumentalities and repurchase agreements
     collateralized by such securities with a weighted average maturity of six
     months or less, i.e., cash or cash equivalents; (ii) 40% of the Fund's
     assets in fixed income securities of the United States government and its
     agencies and instrumentalities with a weighted average maturity of three to
     ten years; and (iii) 40% of the Fund's assets in equity securities that are
     considered by management to have better-than-average prospects for
     appreciation. Assets will be purchased or sold, as the case may be, as is
     necessary in response to changes in market value to maintain the asset mix
     of the Fund's portfolio at approximately 60% cash, cash equivalents and
     fixed income securities and 40% equity securities.

     (Although the Statement of Additional Information for American Century
     Variable Portfolios, Inc. refers to redemptions of securities in kind under
     certain conditions, all surrendering or redeeming contract owners will
     receive cash from Nationwide.)

FIDELITY VARIABLE INSURANCE PRODUCTS FUND
The Fidelity Variable Insurance Products Fund (VIP) is an open-end, diversified,
management investment company organized as a Massachusetts business trust on
November 13, 1981. Shares of VIP are purchased by insurance companies to fund
benefits under variable life insurance policies and variable annuity contracts.
Fidelity Management & Research Company ("FMR") is the manager for the VIP and
its portfolios.

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

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

     BALANCED PORTFOLIO
     Investment Objective: To provide long-term capital growth and reasonable
     current income without undue risk to principal. This Portfolio will seek to
     achieve its objective through investment of a portion of its assets in
     common stocks and a portion of its assets in debt securities. The
     investment adviser anticipates that the Balanced Portfolio's investments
     will normally be managed so that approximately 60% of the Portfolio's total
     assets will be invested in common stocks and the remaining assets will be
     invested in debt securities. However, depending on the investment adviser's
     views regarding current market trends, the common stock portion of the
     Portfolio's investments may be adjusted downward to as low as 50% or upward
     to as high as 70%.




                                       41
<PAGE>   42

     At least 25% of the Portfolio's assets will be invested in fixed income
     senior securities.
