This prospectus offers a variable annuity contract allowing you to accumulate
values and paying you benefits on a variable and/or fixed basis.

Variable annuities provide contract values and lifetime annuity payments that
vary with the investment results of the Funds you choose. You cannot be sure
that the contract value or annuity payments will equal or exceed your purchase
payments.

The variable annuity contracts are designed for:

- - annuity purchase plans adopted by public school systems and certain tax-exempt
  organizations described in Section 501(c)(3) of the Internal Revenue Code (the
  "Code"), qualifying for tax-deferred treatment pursuant to Section 403(b) of
  the Code,

- - other employee pension or profit-sharing trusts or plans qualifying for
  tax-deferred treatment under Section 401(a), 401(k) or 403(a) of the Code,

- - individual retirement annuities qualifying for tax-deferred treatment under
  Section 408 or 408A of the Code, (4) state and municipal deferred compensation
  plans and

- - non-tax-qualified retirement plans.

The minimum initial purchase payment is $10,000. You may make additional
payments of at least $500 at any time ($300 for payroll deduction plans). We may
limit your total purchase payments to $1,500,000.


You may direct the allocation of your purchase payments to one or more (but not
more than 10) subaccounts of Ohio National Variable Account A ("VAA") and/or the
Guaranteed Account. VAA is a separate account of The Ohio National Life
Insurance Company. The assets of VAA are invested in shares of the Funds. The
Funds are portfolios of Ohio National Fund, Inc., the Dow Target Variable Fund
LLC, Goldman Sachs Variable Insurance Trust, Janus Aspen Series, J.P. Morgan
Series Trust II, Lazard Retirement Series, Inc., PBHG Insurance Series Fund,
Inc., The Prudential Series Fund, Inc., Salomon Brothers Variable Series Funds
Inc, Strong Variable Insurance Funds, Inc. and Variable Insurance Products Fund
(Fidelity). See page 2 for the list of available Funds. See also the
accompanying prospectuses of the Funds. The Fund prospectuses might also contain
information about funds that are not available for these contracts.



You may withdraw all or part of the contract's value before annuity payments
begin. You might incur federal income tax penalties for these early withdrawals.
Your exercise of contract rights may be subject to the terms of your qualified
employee trust or annuity plan. This prospectus contains no information
concerning your trust or plan. The prospectus does not provide details of all
our administrative policies and procedures.


You may revoke the contract, without penalty, within 10 days of receiving it (or
a longer period if required by state law).


KEEP THIS PROSPECTUS FOR FUTURE REFERENCE. IT SETS FORTH THE INFORMATION ABOUT
VAA AND THE VARIABLE ANNUITY CONTRACTS THAT YOU SHOULD KNOW BEFORE INVESTING.
ADDITIONAL INFORMATION ABOUT VAA HAS BEEN FILED WITH THE SECURITIES AND EXCHANGE
COMMISSION IN A STATEMENT OF ADDITIONAL INFORMATION DATED MAY 1, 2000. WE HAVE
INCORPORATED THE STATEMENT OF ADDITIONAL INFORMATION BY REFERENCE. IT IS

**The "Other Expenses" (and, accordingly, the Total Fund Expenses) for these
Funds are based on estimates.


The purpose of the above table is to help you to understand the costs and
expenses that you will bear directly or indirectly. [THESE EXAMPLES SHOULD NOT
BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSE. ACTUAL EXPENSES MAY BE
GREATER OR LESS THAN THOSE SHOWN.] For some funds, the "Other Expenses" include
a 12b-1 fee. These fees do not exceed 0.25%. Note that the expense amounts shown
in the examples are aggregate amounts for the total number of years indicated.
In the examples, the annual fee is treated as if it were deducted as a
percentage of assets, based upon the average account value for all contracts,
including ones from which a portion of the contract fee may be paid from amounts
invested in the Guaranteed Account. The above table and examples reflect only
the charges for contracts currently offered by this prospectus and not other
contracts that we may offer.

OHIO NATIONAL LIFE

Ohio National Life was organized under the laws of Ohio on September 9, 1909. We
write life, accident and health insurance and annuities in 47 states, the
District of Columbia and Puerto Rico. Currently we have assets in

excess of $7.6 billion and equity in excess of $725 million. Our home office is
located at One Financial Way, Montgomery, Ohio 45242. We are a stock life
insurance company ultimately owned by a mutual insurance holding company (Ohio
National Mutual Holdings, Inc.). Our policyholders own the majority voting
interest of the holding company.


OHIO NATIONAL VARIABLE ACCOUNT A

We established VAA on August 1, 1969 as a separate account for funding variable
annuity contracts. Purchase payments for the variable annuity contracts are
allocated to one or more subaccounts of VAA. However, contract values may not be
allocated to more than 10 variable subaccounts at any one time. Income, gains
and losses, whether or not realized, from assets allocated to VAA are credited
to or charged against VAA without regard to our other income, gains or losses.
The assets maintained in VAA will not be charged with any liabilities arising
out of any of our other business. Nevertheless, all obligations arising under
the contracts, including the commitment to make annuity payments, are our
general corporate obligations. Accordingly, all our assets are available to meet
our obligations under the contracts. VAA is registered as a unit investment
trust under the Investment Company Act of 1940. The assets of the subaccounts of
VAA are invested at net asset value in Fund shares. Values of other contracts
not offered through this prospectus are also allocated to VAA, including some
subaccounts that are not available for these contracts.

THE FUNDS

The Funds are mutual funds registered under the Investment Company Act 1940.
Fund shares are sold only to insurance company separate accounts to fund
variable annuity contracts and variable life insurance policies and, in some
cases, to qualified plans. The value of each Fund's investments fluctuates daily
and is subject to the risk that Fund management may not anticipate or make
changes necessary in the investments to meet changes in economic conditions.

The Funds receive investment advice from their investment advisers. The Funds
pay each of the investment advisers a fee as shown in the fee table beginning on
page 3. In some cases, the investment adviser pays part of its fee to a
subadviser.

Affiliates of certain Funds may compensate us based upon a percentage of the
Fund's average daily net assets that are allocated to VAA. These percentages
vary by Fund. This is intended to compensate us for administrative and other
services we provide to the Funds and their affiliates.

For additional information concerning the Funds, including their investment
objectives, see the Fund prospectuses. Read them carefully before investing.
They may contain information about other funds that are not available as
investment options for these contracts. You cannot be sure that any Fund will
achieve its stated objectives and policies.

The investment policies, objectives and/or names of some of the Funds may be
similar to those of other investment companies managed by the same investment
adviser or subadviser. However, similar funds often do not have comparable
investment performance. The investment results of the Funds may be higher or
lower than those of the other funds.

MIXED AND SHARED FUNDING

In addition to being offered to VAA, certain Fund shares are offered to our
other separate accounts for variable annuity contracts and a separate account of
Ohio National Life Assurance Corporation for variable life insurance contracts.
Fund shares may also be offered to other insurance company separate accounts and
qualified plans. It is conceivable that in the future it may become
disadvantageous for one or more of variable life and variable annuity separate
accounts, or separate accounts of other life insurance companies, and qualified
plans, to invest in Fund shares. Although neither we nor any of the Funds
currently foresee any such disadvantage, the Board of Directors or Trustees of
each Fund will monitor events to identify any material conflict among different
types of owners

Form 8523

                                       10
<PAGE>   15

and to determine if any action should be taken. That could possibly include the
withdrawal of VAA's participation in a Fund. Material conflicts could result
from such things as:

- - changes in state insurance law;

- - changes in federal income tax law;

- - changes in the investment management of any Fund; or

- - differences in voting instructions given by different types of owners.

VOTING RIGHTS

We will vote Fund shares held in VAA at Fund shareholders meetings in accordance
with voting instructions received from contract owners. We will determine the
number of Fund shares for which you are entitled to give instructions as
described below. This determination will be within 90 days before the
shareholders meeting. Proxy material and forms for giving voting instructions
will be distributed to each owner. We will vote Fund shares held in VAA, for
which no timely instructions are received, in proportion to the instructions
that we do receive

Until annuity payments begin, the number of Fund shares for which you may
instruct us is determined by dividing your contract value in each Fund by the
net asset value of a share of that Fund as of the same date. After annuity
payments begin, the number of Fund shares for which you may instruct us is
determined by dividing the actuarial liability for your variable annuity by the
net asset value of a Fund share as of the same date. Generally, the number of
votes tends to decrease as annuity payments progress.

                   DISTRIBUTION OF VARIABLE ANNUITY CONTRACTS

The variable annuity contracts are sold by our insurance agents who are also
registered representatives of broker-dealers that have entered into distribution
agreements with Ohio National Equities, Inc. "ONEQ" is a wholly-owned subsidiary
of ours. ONEQ is the principal underwriter of the contracts. ONEQ and the
broker-dealers are registered under the Securities Exchange Act of 1934 and are
members of the National Association of Securities Dealers, Inc. We pay ONEQ
7.25% of each purchase payment and ONEQ then pays part of that to the broker-
dealers. The broker-dealers pay their registered representatives from their own
funds. Purchase payments on which nothing is paid to registered representatives
may not be included in amounts on which we pay the sales compensation to ONEQ.
If our surrender charge is not sufficient to recover the fee paid to ONEQ, any
deficiency will be made up from our general assets. These include, among other
things, any profit from the mortality and expense risk charges. ONEQ's address
is One Financial Way, Montgomery, Ohio 45242.

                            DEDUCTIONS AND EXPENSES

SALES CHARGE

No deduction is made for sales expense.

CONTRACT ADMINISTRATION CHARGE

Each year on the contract anniversary (or when you surrender of the contract),
we will deduct a contract administration charge of $30 from the contract value.
This helps to repay us for maintaining the contract. There is no contract
administration charge for contracts having a value of at least $50,000. There is
no charge after annuity payments begin. We guarantee not to increase the
contract administration charge.

DEDUCTION FOR ADMINISTRATIVE EXPENSES

At the end of each valuation period we deduct an amount equal to 0.25% on an
annual basis of the contract value. This deduction reimburses us for expenses
not covered by the contract administration charge. Examples of these expenses
are accounting, auditing, legal, contract owner services, reports to regulatory
authorities and contract owners, contract issue, etc.

DEDUCTION FOR RISK UNDERTAKINGS

We guarantee that, until annuity payments begin, the contract's value will not
be affected by any excess of sales and administrative expenses over the
deductions for them. We also guarantee to pay a death benefit if the annuitant
dies before annuity payments begin. After annuity payments begin, we guarantee
that variable annuity payments will not be affected by adverse mortality
experience or expenses.

For assuming these risks, when we determine the accumulation unit values and the
annuity unit values for each subaccount, we make a deduction from the applicable
investment results equal to 1.25% of the contract value on an annual basis. We
may decrease that deduction at any time and we may increase it not more often
than annually to not more than 1.25% on an annual basis. We agree that the
deduction for these risk undertakings shall not be increased to more than the
rate in effect at the time the contract is issued. We may discontinue this
limitation on our right to increase the deduction, but only as to contracts
purchased after notice of the discontinuance. The risk charge is an indivisible
whole of the amount currently being deducted. However, we believe that a
reasonable allocation would be 0.65% for mortality risk, and 0.60% for expense
risk. We hope to realize a profit from this charge. However there will be a loss
if the deduction fails to cover the actual risks involved.

TRANSFER FEE

We may charge a transfer fee of $10 for each transfer from one or more
subaccounts to other subaccounts. The fee is charged pro rata against the
subaccounts from which the transfer is made. We do not charge for your first
transfer each calendar month.

DEDUCTION FOR STATE PREMIUM TAX

Most states do not presently charge a premium tax for these contracts. Where a
tax applies, the rates for tax-qualified contracts are presently 0.5% in
California, 1.0% in Puerto Rico and West Virginia, 2.0% in Kentucky and 2.25% in
the District of Columbia. For non-tax-qualified contracts, the rates are
presently 1.0% in Puerto Rico, West Virginia and Wyoming, 1.25% in the South
Dakota, 2.0% in Kansas, Kentucky and Maine, 2.25% in the District of Columbia,
2.35% in California and 3.5% in Nevada. The deduction for premium taxes will be
made when incurred. Normally, that is not until annuity payments begin. However,
in Kansas, South Dakota and Wyoming, they are presently being deducted from
purchase payments.

FUND EXPENSES

There are deductions from, and expenses paid out of, the assets of the Funds.
These are described in the Fund prospectuses.

                   DESCRIPTION OF VARIABLE ANNUITY CONTRACTS

10-DAY FREE LOOK

You may revoke the contract at any time until the end of 10 days after you
receive it (or such longer period as may be required by your state law) and get
a refund of the contract value as of the date of cancellation. To revoke, you
must return the contract to us within the free look period. In Georgia, Idaho,
Indiana, Nebraska, Nevada, North Carolina, Oklahoma, South Carolina, Utah and
Washington, state law requires that the original purchase price be returned in
lieu of the current contract value if you exercise your free look. Any purchase
payments in these states to be allocated to variable Funds will first be
allocated to the Money Market Fund until the end of the free look period.

<PAGE>   17

                              ACCUMULATION PERIOD

PURCHASE PAYMENTS


Your first purchase payment must be at least $10,000. You do not have to make
any more payments after that. But you may make additional purchase payments at
any time of at least $500 each ($300 for payroll deduction plans). We may limit
your total purchase payments to $1,500,000.


ACCUMULATION UNITS

Until the annuity payout date, the contract value is measured by accumulation
units. As you make each purchase payment, we credit units to the contract (see
Crediting Accumulation Units). The number of units remains constant between
purchase payments but their dollar value varies depending upon the investment
results of each Fund to which payments are allocated.

CREDITING ACCUMULATION UNITS

Your representative will send an order or application, together with the first
purchase payment, to our home office for acceptance. Upon acceptance, we issue a
contract and we credit the first purchase payment to the contract in the form of
accumulation units. If all information necessary for issuing a contract and
processing the purchase payment is complete, we will credit your first purchase
payment within two business days after receipt. If we do not receive everything
within five business days, we will return the purchase payment to you
immediately unless you specifically consent to having us retain the purchase
payment until the necessary information is completed. After that, we will credit
the purchase payment within two business days.

You must send any additional purchase payments directly to our home office. They
will then be applied to provide that number of accumulation units (for each
subaccount) determined by dividing the amount of the purchase payment by the
unit value next computed after we receive the payment at our home office.

ALLOCATION OF PURCHASE PAYMENTS

You may allocate your purchase payments among up to 10 variable subaccounts of
VAA and to the Guaranteed Account. The amount you allocate to any Fund or the
Guaranteed Account must equal a whole percent You may change your allocation of
future purchase payments at any time by sending written notice to our home
office.

ACCUMULATION UNIT VALUE AND ACCUMULATION VALUE

We set the accumulation unit value of each subaccount of VAA at $10 when we
credited the first payments for these contracts. We determine the unit value for
any later valuation period by multiplying the unit value for the immediately
preceding valuation period by the net investment factor (described below) for
such later valuation period. We determine a contract's value by multiplying the
total number of units (for each subaccount) credited to the contract by the unit
value (for such subaccount) for the current valuation period.

NET INVESTMENT FACTOR

The net investment factor measures the investment results of each subaccount.
The net investment factor for each subaccount for any valuation period is
determined by dividing (a) by (b), then subtracting (c) from the result, where:

(a) is

     (1) the net asset value of the corresponding Fund share at the end of a
         valuation period, plus

     (2) the per share amount of any dividends or other distributions declared
         for that Fund if the "ex-dividend" date occurs during the valuation
         period, plus or minus

Form 8523

                                       13
<PAGE>   18

     (3) a per share charge or credit for any taxes paid or reserved for the
         maintenance or operation of that subaccount; (no federal income taxes
         apply under present law.)

(b) is the net asset value of the corresponding Fund share at the end of the
    preceding valuation period; and

(c) is the deduction for administrative and sales expenses and risk
    undertakings.

SURRENDER AND PARTIAL WITHDRAWAL

Before annuity payments begin (and also after that in the case of annuity Option
1(e) described below) you may surrender (totally withdraw the value of) your
contract or elect a partial withdrawal (at least $1,000). In the case of a
complete surrender, we subtract any contract administration charge. We will pay
you within seven days after we receive your request. However, we may defer
payment described below. Surrenders and partial withdrawals are limited or not
permitted in connection with certain retirement plans. For tax consequences of a
surrender or withdrawal, see Federal Tax Status.

If you request a surrender or partial withdrawal which includes contract values
derived from purchase payments that have not yet cleared the banking system, we
may delay mailing the portion relating to such payments until your check has
cleared. We require the return of the contract in the case of a complete
surrender.

Your right to withdraw may be suspended or the date of payment postponed:

(1) for any period during which the New York Stock Exchange is closed (other
    than customary weekend and holiday closings) or during which the Securities
    and Exchange Commission has restricted trading on the Exchange;

(2) for any period during which an emergency, as determined by the Commission,
    exists as a result of which disposal of securities held in a Fund is not
    reasonably practical, or it is not reasonably practical to determine the
    value of a Fund's net assets; or

(3) such other periods as the Commission may order to protect security holders.

TRANSFERS AMONG SUBACCOUNTS

You may transfer contract values from one or more Funds to one or more other
Funds. You may make transfers at any time before annuity payments begin. The
amount of any transfer must be at least $300 (or the entire value of the
contract's interest in a Fund, if less).

We may limit the number, frequency, method or amount of transfers. We may limit
transfers from any Fund on any one day to 1% of the previous day's total net
assets of that Fund if we or the Fund in our discretion, believe that the Fund
might otherwise be damaged. In determining which requests to honor, scheduled
transfers (under a DCA program) will be made first, followed by mailed written
requests in the order postmarked and, lastly, telephone and facsimile requests
in the order received. We will notify you if your requested transfer is not
made. Current SEC rules preclude us from processing at a later date those
requests that were not made. Accordingly, you would need to submit a new
transfer request in order to make a transfer that was not made because of these
limitations.

Certain third parties may offer you asset allocation or timing services for your
contract. We may choose to honor transfer requests from these third parties if
you give us a written power of attorney to do so. Fees you pay for such asset
allocation or timing services are in addition to any contract charges. WE DO NOT
ENDORSE, APPROVE OR RECOMMEND THESE SERVICES.

After annuity payments begin, you may make transfers among Funds only once each
calendar quarter. The transfer fee no longer applies then. Not more than 20% of
a contract's Guaranteed Account value (or $1,000, if greater) as of the
beginning of a contract year may be transferred to variable Funds during that
contract year.

                                       14
<PAGE>   19

TELEACCESS

If you give us a pre-authorization form, your contract and unit values and
interest rates can be checked and transfers may be made by telephoning us
between 7:00 a.m. and 7:00 p.m. (Eastern time) on days that we are open for
business, at 1-800-366-6654, #8. You may only make one telephone transfer per
day. We will honor pre-authorized telephone transfer instructions from anyone
who provides the personal identifying information requested via TeleAccess. We
will not honor telephone transfer requests after we receive notice of your
death. For added security, we send the contract owner a written confirmation of
all telephone transfers on the next business day. However, if we cannot complete
a transfer as requested, our customer service representative will contact the
owner in writing sent within 48 hours of the TeleAccess request. [YOU MAY THINK
THAT YOU HAVE LIMITED THIS ACCESS TO YOURSELF, OR TO YOURSELF AND YOUR
REPRESENTATIVE. HOWEVER, ANYONE GIVING US THE NECESSARY IDENTIFYING INFORMATION
CAN USE TELEACCESS ONCE YOU AUTHORIZE IT.]

SCHEDULED TRANSFERS (DOLLAR COST AVERAGING)

We administer a scheduled transfer ("DCA") program enabling you to preauthorize
automatic monthly or quarterly transfers of a specified dollar amount of at
least $300 each time. At least 12 DCA transfers must be scheduled. The transfers
may be from any variable Funds to any other Funds or to the Guaranteed Account.
Transfers may be made from the Guaranteed Account to any other Funds if the DCA
program is established at the time the contract is issued, the DCA program is
scheduled to begin within 6 months of contract issue and the term of the DCA
program does not exceed 2 years. For transfers from variable Funds, the DCA
program may not exceed 5 years. There is no transfer fee for DCA transfers. DCA
transfers do not count as the free transfer you are allowed once each calendar
month. We may discontinue the DCA program at any time. You may also discontinue
further DCA transfers by giving us written notice at least 7 business days
before the next scheduled transfer.

DCA generally has the effect of reducing the risk of purchasing at the top, and
selling at the bottom, of market cycles. DCA transfers from the Guaranteed
Account or from a Fund with a stabilized net asset value, such as the Money
Market Fund, will generally reduce the average total cost of indirectly
purchasing Fund shares because greater numbers of shares will be purchased when
the share prices are lower than when prices are higher. However, DCA does not
assure you of a profit, nor does it protect against losses in a declining
market. Moreover, for transfers from a variable Fund, DCA has the effect of
reducing the average price of the shares being redeemed. DCA might also be used
to systematically transfer contract values from variable Funds to the Guaranteed
Account in anticipation of retirement, reducing the risk of making a single
transfer during a low market.

PORTFOLIO REBALANCING

You may have us automatically transfer amounts on a quarterly, semi-annual or
annual basis to maintain a specified percentage (whole percentages only) of
contract value in each of two or more designated Funds. The purpose of a
portfolio rebalancing strategy is to maintain, over time, your desired
allocation percentage in the designated Funds having differing investment
performance. Portfolio rebalancing will not necessarily enhance future
performance or protect against future losses.


To elect, change or discontinue this option, you must give us written
authorization. The transfer charge does not apply to portfolio rebalancing
transactions. These transactions do not count against the free transfer you are
allowed once each calendar month. You may not have portfolio rebalancing for any
Funds that are part of a DCA program.


DEATH BENEFIT

If the annuitant (and any contingent annuitant) dies before annuity payments
begin, the contract pays a death benefit to a designated beneficiary. (Death
benefits are not available on any contract purchased through a bank in Puerto
Rico.) The amount of the death benefit will be determined as of the date of the
annuitant's death. It will

Form 8523

                                       15
<PAGE>   20

be paid to the beneficiary in a single sum unless you elect settlement under one
or more of the settlement options. If the death benefit is not claimed within 90
days after the date of death, we will pay the contract value instead of any
greater death benefit.

This death benefit will be the greater of:

- - the contract value; or

- - the net of purchase payments less withdrawals.

In those states where permitted, you may elect an optional annual stepped-up
death benefit at the time the contract is issued. With that option, the death
benefit on the first contract anniversary will be the greater of (a) the
contract value then or (b) the net of purchase payments minus withdrawals made
on or before that date. On each contract anniversary after that (until the
annuitant attains age 80), the death benefit will be reset to the greater of (a)
the contract value on that anniversary date or (b) the death benefit as of the
last preceding anniversary. The death benefit is increased by purchase payments
and decreased by withdrawals made during the year before each anniversary. There
is an additional charge (presently at an annual rate of 0.05% of the optional
death benefit amount, which rate may be increased to no more than 0.25% on
contracts issued in the future) for this optional benefit.

In those states where permitted, you may elect a guaranteed minimum death
benefit at the time the contract is issued. With this option, the death benefit
is the greater of (a) the contract value on the date of death or (b) the
guaranteed minimum death benefit amount. The guaranteed minimum death benefit
amount for contract values held in the Guaranteed Account and the Money Market
Fund is the contract value as of the date of death. For all other subaccounts,
the guaranteed minimum death benefit amount is (i) the net of purchase payments
less withdrawals plus (ii) a daily increase, until the annuitant attains age 80,
at an effective annual rate of 6%. There is an additional charge for this option
of 0.25% of the guaranteed minimum death benefit amount.

GUARANTEED ACCOUNT

The Guaranteed Account guarantees a fixed return for a specified period of time
and guarantees the principal against loss. The Guaranteed Account is not
registered as an investment company. Interests in it are not subject to the
provisions or restrictions of federal securities laws. The staff of the
Securities and Exchange Commission has not reviewed disclosures regarding it.

The Guaranteed Account consists of all of our general assets other than those
allocated to a separate account. You may allocate purchase payments and contract
values between the Guaranteed Account and the Funds.

We invest our general assets in our discretion as allowed by Ohio law. We
allocate the investment income from our general assets to those contracts having
guaranteed values.

The amount of investment income allocated to the contracts varies from year to
year in our sole discretion. However, we guarantee that we will credit interest
at a rate of not less than 3% per year, compounded annually, to contract values
allocated to the Guaranteed Account. We may credit interest at a rate in excess
of 3%, but any such excess interest credit will be in our sole discretion.

We guarantee that, before annuity payments begin, the guaranteed value of a
contract will never be less than:

- - the amount of purchase payments allocated to, and transfers into, the
  Guaranteed Account, plus

- - interest credited at the rate of 3% per year compounded annually, plus

- - any additional excess interest we may credit to guaranteed values, minus

- - any partial withdrawals, loans and transfers from the guaranteed values, minus

- - any loan interest, state premium taxes, transfer fees, and the portion of the
  $30 annual contract administration charge allocable to the Guaranteed Account.

No deductions are made from the Guaranteed Account for administrative expenses
or risk undertakings.

Form 8523

                                       16
<PAGE>   21

Other than pursuant to a DCA (scheduled transfer) or portfolio rebalancing
program, we may restrict transfers of your Guaranteed Account value during a
contract year to not more than 20% of that value as of the beginning of a
contract year (or $1,000, if greater). As provided by state law, we may defer
the payment of amounts to be withdrawn from the Guaranteed Account for up to six
months from the date we receive your written request for withdrawal.

OHIO NATIONAL LIFE EMPLOYEE DISCOUNT

We and our affiliated companies offer a credit on the purchase of contracts by
any of our employees, directors or retirees, or their spouse or the surviving
spouse of a deceased retiree, their minor children, or any of their children
ages 18 to 21 who is either (i) living in the purchaser's household or (ii) a
full-time college student being supported by the purchaser, or any of the
purchaser's minor grandchildren under the Uniform Gifts to Minors Act. This
credit counts as additional income under the contract. The amount of the credit
equals 3.2% of all purchase payments made in the first contract year and 5.5% of
purchase payments made in the second through sixth contract years. We credit the
Guaranteed Account in these amounts at the time the eligible person makes each
payment.

TEXAS STATE OPTIONAL RETIREMENT PROGRAM

Under the Texas State Optional Retirement Program (the "Program"), purchase
payments may be excluded from the gross income of state employees for federal
tax purposes to the extent that such purchase payments do not exceed the
exclusion allowance provided by the Code. The Attorney General of Texas has
interpreted the Program as prohibiting any participating state employee from
receiving the surrender value of a contract funding benefits under the Program
prior to termination of employment or the state employee's retirement, death or
total disability. Therefore, a participant in the Program may not make a
surrender or partial withdrawal until the first of these events occurs.

                                 ANNUITY PERIOD

ANNUITY PAYOUT DATE

Annuity payments begin on the annuity payout date. You may select this date when
the contract is issued. It must be at least 30 days after the contract date. You
may change it from time to time so long as it is the first day of any month at
least 30 days after the date of such change. The contract restricts the annuity
payout date to not later than the first of the month following the annuitant's
90th birthday. This restriction may be modified by applicable state law or we
may agree to waive it.

The contracts include our guarantee (except for option 1(e) below) that we will
pay annuity payments for the lifetime of the annuitant (and any joint annuitant)
in accordance with the contract's annuity rates, no matter how long you live.

Other than in connection with annuity Option 1(e) described below, once annuity
payments begin, you may not surrender the contract for cash except that, upon
the death of the annuitant, the beneficiary may surrender the contract for the
commuted value of any remaining period-certain payments. You may make surrenders
and partial withdrawals from Option 1(e) at any time.

ANNUITY OPTIONS

You may elect one or more of the following annuity options. You may change the
election anytime before the annuity payout date.

Option 1(a):   Life Annuity with installment payments for the lifetime of the
               annuitant. (The contract has no more value after the annuitant's
               death).

Form 8523

                                       17
<PAGE>   22

Option 1(b):  Life Annuity with installment payments guaranteed for five years
              and then continuing during the remaining lifetime of the
              annuitant.

Option 1(c):  Life Annuity with installment payments guaranteed for ten years
              and then continuing during the remaining lifetime of the
              annuitant.

Option 1(d):  Installment Refund Life Annuity with payments guaranteed for a
              period certain and then continuing during the remaining lifetime
              of the annuitant. The number of period-certain payments is equal
              to the amount applied under this option divided by the amount of
              the first payment.

Option 1(e):  Installment Refund Annuity with payments guaranteed for a fixed
              number (up to thirty) of years. This option is available for
              variable annuity payments only. (Although the deduction for risk
              undertakings is taken from annuity unit values, we have no
              mortality risk during the annuity payout period under this
              option.)

Option 2(a):  Joint & Survivor Life Annuity with installment payments during the
              lifetime of the annuitant and then continuing during the lifetime
              of a contingent annuitant. (The contract has no more value after
              the second annuitant's death.)

Option 2(b):  Joint & Survivor Life Annuity with installment payments guaranteed
              for ten years and then continuing during the remaining lifetime of
              the annuitant or a contingent annuitant.

We may agree to other settlement options.

Unless you direct otherwise, we will apply the contract value as of the annuity
payout date to provide annuity payments pro-rata from each Fund in the same
proportion as the contract values immediately before the annuity payout date.

If no election is in effect on the annuity payout date, we will apply contract
value under Option 1(c) with the beneficiary as payee for any remaining
period-certain installments payable after the death of the annuitant. The
Pension Reform Act of 1974 might require certain contracts to provide a Joint
and Survivor Annuity. If the contingent annuitant is not related to the
annuitant, Options 2(a) and 2(b) are available only if we agree.

The Internal Revenue Service has not ruled on the tax treatment of a commutable
variable annuity. If you select Option 1(e), it is possible that the IRS could
determine that the entire value of the annuity is fully taxable at the time you
elect Option 1(e) or that variable annuity payments under this option should not
be taxed under the annuity rules (see Federal Tax Status). This could result in
your payments being fully taxable to you. Should the IRS so rule, we may have to
tax report up to the full value of the annuity as your taxable income.

DETERMINATION OF AMOUNT OF THE FIRST VARIABLE ANNUITY PAYMENT

To determine the first variable annuity payment we apply the contract value for
each Fund in accordance with the contract's settlement option tables. The rates
in those tables depend upon the annuitant's (and any contingent annuitant's) age
and sex and the option selected. The annuitant's sex is not a factor in
contracts issued to plans sponsored by employers subject to Title VII of the
Civil Rights Act of 1964 or similar state statutes. We determine the value to be
applied at the end of a valuation period (selected by us and uniformly applied)
not more than 10 valuation periods before the annuity payout date.

If the amount that would be applied under an option is less than $5,000, we will
pay the contract value to the annuitant in a single sum. If the first periodic
payment under any option would be less than $25, we may change the frequency of
payments so that the first payment is at least $25.

ANNUITY UNITS AND VARIABLE PAYMENTS

After your first annuity payment, later variable annuity payments will vary to
reflect the investment performance of your Funds. The amount of each payment
depends on the number of your annuity units. To determine the

Form 8523

                                       18
<PAGE>   23

number of annuity units for each Fund, divide the dollar amount of the first
annuity payment from each Fund by the value that Fund's annuity unit. This
number of annuity units remains constant during the annuity payment period
unless you transfer among Funds.

The annuity unit value for each Fund was set at $10 for the valuation period
when the first variable annuity was calculated for these contracts. The annuity
unit value for each later valuation period equals the annuity unit value for the
immediately preceding valuation period multiplied by the net investment factor
(described on page 11) for such later valuation period and by a factor (0.999919
for a one-day valuation period) to neutralize the 3% assumed interest rate
discussed below.

The dollar amount of each later variable annuity payment equals your constant
number of annuity units for each Fund multiplied by the value of the annuity
unit for the valuation period.

The annuity rate tables contained in the contracts are based on the 1983(a)
Mortality Table Projected to 1996 under Scale G with compound interest at the
effective rate of 3% per year. A higher interest assumption would mean a higher
initial annuity payment but a more slowly rising series of subsequent annuity
payments if annuity unit values were increasing (or a more rapidly falling
series of subsequent annuity payments if annuity unit values were decreasing). A
lower interest assumption would have the opposite effect. If the actual net
investment rate were equal to the assumed interest rate, annuity payments would
stay level.

TRANSFERS DURING ANNUITY PAYOUT

After annuity payments have been made for at least 12 months, the annuitant can,
once each calendar quarter, change the Funds on which variable annuity payments
are based. On at least 30 days written notice our home office we will change
that portion of the periodic variable annuity payment as you direct to reflect
the investment results of different Funds. The annuity payment immediately after
a change will be the amount that would have been paid without the change. Later
payments will reflect the new mix of Funds.

                           OTHER CONTRACT PROVISIONS

ASSIGNMENT

Amounts payable in settlement of a contract may not be commuted, anticipated,
assigned or otherwise encumbered, or pledged as loan collateral to anyone other
than us. To the extent permitted by law, such amounts are not subject to any
legal process to pay any claims against an annuitant before annuity payments
begin. The owner of a tax-qualified contract may not, but the owner of a
non-tax-qualified contract may, collaterally assign the contract before the
annuity payout date. Ownership of a tax-qualified contract may not be
transferred except to:

- - the annuitant,

- - a trustee or successor trustee of a pension or profit-sharing trust which is
  qualified under Section 401 of the Code,

- - the employer of the annuitant provided that the contract after transfer is
  maintained under the terms of a retirement plan qualified under Section 403(a)
  of the Code for the benefit of the annuitant, or

- - as otherwise permitted by laws and regulations governing plans for which the
  contract may be issued.

PERIODIC REPORTS

Before the annuity payout date, we will send you quarterly statements showing
the number of units credited to the contract by Fund and the value of each unit
as of the end of the last quarter. In addition, as long as the contract remains
in effect, we will forward any periodic Fund reports.

<PAGE>   24

SUBSTITUTION FOR FUND SHARES

If investment in a Fund is no longer possible or we believe it is inappropriate
to the purposes of the contract, we may substitute one or more other funds.
Substitution may be made as to both existing investments and the investment of
future purchase payments. However, no substitution will be made until we receive
any necessary approval of the Securities and Exchange Commission. We may also
add other Funds as eligible investments of VAA.

                            CONTRACT OWNER INQUIRIES

Direct any questions to Ohio National Life, Variable Annuity Administration,
P.O. Box 2669, Cincinnati, Ohio 45201; telephone 1-800-366-6654 (8:30 a.m. to
4:30 p.m., Eastern time).


PERFORMANCE DATA


We may advertise performance data for the various Funds showing the percentage
change in unit values based on the performance of the applicable Fund over a
period of time (usually a calendar year). We determine the percentage change by
dividing the increase (or decrease) in value for the unit by the unit value at
the beginning of the period. This percent reflects the deduction of any
asset-based contract but does not reflect the deduction of any applicable
contract administration charge or surrender charge. The deduction of a contract
administration charge or surrender charge would reduce any percentage increase
or make greater any percentage decrease.

                               FEDERAL TAX STATUS

The following discussion of federal income tax treatment of amounts received
under a variable annuity contract does not cover all situations or issues. It is
not intended as tax advice. Consult a qualified tax adviser to apply the law to
your circumstances. Tax laws can change, even for contracts that have already
been issued. Tax law revisions, with unfavorable consequences, could have
retroactive effect on previously issued contracts or on later voluntary
transactions in previously issued contracts.

We are taxed as a life insurance company under Subchapter L of the Internal
Revenue Code (the "Code"). Since the operations of VAA are a part of, and are
taxed with, our operations, VAA is not separately taxed as a "regulated
investment company" under Subchapter M of the Code.

As to tax-qualified contracts, the law does not now provide for payment of
federal income tax on dividend income or capital gains distributions from Fund
shares held in VAA or upon capital gains realized by VAA on redemption of Fund
shares. When a non-tax-qualified contract is issued in connection with a
deferred compensation plan or arrangement, all rights, discretions and powers
relative to the contract are vested in the employer and you must look only to
your employer for the payment of deferred compensation benefits. Generally, in
that case, an annuitant will have no "investment in the contract" and amounts
received by you from your employer under a deferred compensation arrangement
will be taxable in full as ordinary income in the years you receive the
payments.

The income and gains within an annuity contract are generally tax deferred.
Within a tax-qualified plan, the plan itself provides tax deferral. Therefore,
the tax-deferred treatment otherwise available to an annuity contract is not a
factor to consider when purchasing an annuity within a tax-qualified plan or
arrangement.


The contracts are considered annuity contracts under Section 72 of the Code,
which generally provides for taxation of annuities. Under existing provisions of
the Code, any increase in the contract value is not taxable to you as the owner
or annuitant until you receive it, either in the form of annuity payments, as
contemplated by the contract, or in some other form of distribution. The owner
of a non-tax qualified contract must be a natural person for this purpose. With
certain exceptions, where the owner of a non-tax qualified contract is a
non-natural person (corporation, partnership or trust) any increase in the
accumulation value of the contract attributable to purchase payments made after
February 28, 1986 will be treated as ordinary income received or accrued by the
contract owner during the current tax year.

When annuity payments begin each payment is taxable under Section 72 of the Code
as ordinary income in the year of receipt if you have neither paid any portion
of the purchase payments nor previously been taxed on any portion of the
purchase payments. If any portion of the purchase payments has been paid from or
included in your taxable income, this aggregate amount will be considered your
"investment in the contract." You will be entitled to exclude from your taxable
income a portion of each annuity payment equal to your "investment in the
contract" divided by the period of expected annuity payments, determined by your
life expectancy and the form of annuity benefit. Once you recover your
"investment in the contract," all further annuity payments will be included in
your taxable income.

If you elect to receive the accumulated value in a single sum in lieu of annuity
payments, any amount you receive or withdraw in excess of the "investment in the
contract" will normally be taxed as ordinary income in the year received. A
partial withdrawal of contract values is taxable as income to the extent that
the accumulated value of the contract immediately before the payment exceeds the
"investment in the contract." Such a withdrawal is treated as a distribution of
earnings first and only second as a recovery of your "investment in the
contract." Any part of the value of the contract that you assign or pledge to
secure a loan will be taxed as if it had been a partial withdrawal and may be
subject to a penalty tax.

There is a penalty tax equal to 10% of any amount that must be included in gross
income for tax purposes. The penalty will not apply to a redemption that is:

- - received on or after the taxpayer reaches age 59 1/2;

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

- - attributable to the taxpayer's becoming disabled;

- - made as a series of substantially equal periodic payments for the life of the
  annuitant (or joint lives of the annuitant and beneficiary);

- - from a contract that is a qualified funding asset for purposes of a structured
  settlement;

- - made under an annuity contract that is purchased with a single premium and
  with an annuity payout date not later than a year from the purchase of the
  annuity;

- - incident to divorce, or

- - taken from an IRA for a qualified first-time home purchase (up to $10,000) or
  qualified education expenses.

If you elect not to have withholding apply to an early withdrawal or if an
insufficient amount is withheld, you may be responsible for payment of estimated
tax. You may also incur penalties under the estimated tax rules if the
withholding and estimated tax payments are not sufficient. If you fail to
provide your taxpayer identification number, any payments under the contract
will automatically be subject to withholding.

TAX-DEFERRED ANNUITIES


Under the provisions of Section 403(b) of the Code, employees may exclude from
their gross income purchase payments made for annuity contracts purchased for
them by public educational institutions and certain tax-exempt organizations
which are described in Section 501(c)(3) of the Code. You may make this
exclusion to the extent that the aggregate purchase payments plus any other
amounts contributed to purchase the contract and toward benefits under qualified
retirement plans do not exceed your exclusion allowance as determined in
Sections 403(b) and 415 of the Code. Employee contributions are, however,
subject to social security (FICA) tax withholding. All amounts you receive under
a contract, either in the form of annuity payments or cash withdrawal, will be
taxed under Section 72 of the Code as ordinary income for the year received,
except for exclusion of any amounts representing "investment in the contract."
Under certain circumstances, amounts you receive may be used to make a "tax-free
rollover" into one of the types of individual retirement arrangements permitted
under the Code. Amounts you receive that are eligible for "tax-free rollover"
will be subject to an automatic 20% withholding unless you directly roll over
such amounts from the tax-deferred annuity to the individual retirement
arrangement.

With respect to earnings accrued and purchase payments made after December 31,
1988, for a salary reduction agreement under Section 403(b) of the Code,
distributions may be paid only when the employee:

- - attains age 59 1/2,

- - separates from the employer's service,

- - dies,

- - becomes disabled as defined in the Code, or

- - incurs a financial hardship as defined in the Code.

In the case of hardship, cash distributions may not exceed the amount of your
purchase payments. These restrictions do not affect your right to transfer
investments among the Funds and do not limit the availability of transfers
between tax-deferred annuities.


QUALIFIED PENSION OR PROFIT-SHARING PLANS


Under present law, purchase payments made by an employer or trustee, for a plan
or trust qualified under Section 401(a) or 403(a) of the Code, are generally
excludable from the employees gross income. Any purchase payments made by the
employee, or which are considered taxable income to the employee in the year
such payments are made, constitute an "investment in the contract" under Section
72 of the Code for the employee's annuity benefits. Salary reduction payments to
a profit sharing plan qualifying under Section 401(k) of the Code are generally
excludable from the employee's gross income.

The Code requires plans to prohibit any distribution to a plan participant prior
to age 59 1/2, except in the event of death, total disability or separation from
service (special rules apply for plan terminations). Distributions must begin no
later than April 1 of the calendar year following the year in which the
participant reaches age 70 1/2. Premature distribution of benefits or
contributions in excess of those permitted by the Code may result in certain
penalties under the Code.

If an employee, or one or more of the beneficiaries, receives the total amounts
payable with respect to an employee within one taxable year after age 59 1/2 on
account of the employee's death or separation from service of the employer, any
amount received in excess of the employee's "investment in the contract" may be
taxed under special 5-year forward averaging rules. Five-year averaging will no
longer be available after 1999 except for certain grandfathered individuals. You
can elect to have that portion of a lump-sum distribution attributable to years
of participation prior to January 1, 1974 given capital gains treatment. The
percentage of pre-74 distribution subject to capital gains treatment decreases
as follows: 100%, 1987; 95%, 1988; 75%, 1989; 50%, 1990; and 25%, 1991. For tax
years 1992 and later no capital gains treatment is available (except that
taxpayers who were age 50

Form 8523

                                       22
<PAGE>   27

before 1986 may still elect capital gains treatment). If you receive such a
distribution you may be able to make a "tax-free rollover" of the distribution
less your "investment in the contract" into another qualified plan in which you
are a participant or into one of the types of individual retirement arrangements
permitted under the Code. Your surviving spouse receiving such a distribution
may be able to make a tax-free rollover to one of the types of individual
retirement arrangements permitted under the Code. Amounts received that are
eligible for "tax-free rollover" will be subject to an automatic 20% withholding
unless such amounts are directly rolled over to another qualified plan or
individual retirement arrangement.


INDIVIDUAL RETIREMENT ANNUITIES (IRA)


Section 408(b) of the Code provides that an individual may invest an amount up
to $2,000 per year of earned income in an IRA and claim it as a personal tax
deduction if such person is not an "active participant" in an employer
maintained qualified retirement plan or such person has adjusted gross income
which does not exceed the "applicable dollar limit." For a single taxpayer, the
applicable dollar limitation is $30,000, with the amount of IRA contribution
which may be deducted reduced proportionately for Adjusted Gross Income between
$30,000-$40,000. For married couples filing jointly, the applicable dollar
limitation is $50,000, with the amount of IRA contribution which may be deducted
reduced proportionately for Adjusted Gross Income between $50,000-$60,000. There
is no deduction allowed for IRA contributions when Adjusted Gross Income reaches
$40,000 for individuals and $60,000 for married couples filing jointly. In the
alternative, an individual otherwise qualified for an IRA may elect to
contribute to an IRA for the individual and for the individual's non-working
spouse, with the total deduction limited to $4,000.

You may make non-deductible IRA contributions to the extent they are ineligible
to make deductible IRA contributions. Any amount received from another qualified
plan (including another individual retirement arrangement) which is eligible as
a "tax-free rollover" may be invested in an IRA, and is not counted toward the
overall contribution limit. Earnings on nondeductible IRA contributions are not
subject to tax until they are withdrawn. The combined limit on designated
nondeductible and deductible contributions for a tax year is the lesser of 100%
of compensation or $2,000 ($4,000 in the case of an additional contribution to a
spousal IRA).

Generally, distributions (all or part) made prior to age 59 1/2 (except in the
case of death or disability) will result in a penalty tax of 10% plus ordinary
income tax treatment of the amount received. Additionally, there is an excise
tax of 6% of the amount contributed in excess of either the deductible limit or
nondeductible limit, as indicated above, if such amount is not withdrawn prior
to the filing of the income tax return for the year of contribution or applied
as an allowable contribution for a subsequent year. The excise tax will continue
to apply each year until the excess contribution is corrected. Distributions
after age 59 1/2 are treated as ordinary income at the time received.
Distributions must commence before April 1 following the year in which the
individual reaches age 70. A 50% nondeductible excise tax is imposed on the
excess in any tax year of the amount that should have been distributed over the
amount actually distributed.

Section 408A of the Code provides for a special type of IRA called a Roth IRA.
No tax deduction is allowed for contributions to a Roth IRA, but assets grow on
a tax-deferred basis. Under certain circumstances, withdrawals from a Roth IRA
can be excludable from income. Eligibility for a Roth IRA is based on adjusted
gross income and filing status. Special rules apply which allow traditional IRAs
to be rolled over or converted to a Roth IRA.


SIMPLIFIED EMPLOYEE PENSION PLANS (SEPPS)


Under Section 408 of the Code, employers may establish SEPPs for their
employees. Under these plans the employer may contribute on behalf of an
employee to an individual retirement account or annuity. The amount of the
contribution is excludable from the employee's income.

Certain employees who participate in a SEPP will be entitled to elect to have
the employer make contributions to a SEPP on their behalf or to receive the
contributions in cash. If the employee elects to have contributions made on the
employee's behalf to a SEPP, it is not treated as current taxable income to the
employee. Elective deferrals

Form 8523

                                       23
<PAGE>   28

under a SEPP are subject to an inflation-indexed limit which is $10,000 for
1998. Salary-reduction SEPPs are available only if at least 50% of the employees
elect to have amounts contributed to the SEPP and if the employer has 25 or
fewer employees at all times during the preceding year. New salary-reduction
SEPPs may not be established after 1996.

An employee may also take a deduction for individual contributions to the IRA,
subject to the limits applicable to IRAs in general. Withdrawals from the IRAs
to which the employer contributes must be permitted. These withdrawals, however,
are subject to the general rules with respect to withdrawals from IRAs.


WITHHOLDING ON DISTRIBUTION


Distributions from tax-deferred annuities or qualified pension or profit sharing
plans that are eligible for "tax-free rollover" will be subject to an automatic
20% withholding unless such amounts are directly rolled over to an individual
retirement arrangement or another qualified plan. Federal income tax withholding
is required on annuity payments. However, recipients of annuity payments are
allowed to elect not to have the tax withheld. This election may be revoked at
any time and withholding would begin after that. If you do not give us your
taxpayer identification number any payments under the contract will
automatically be subject to withholding.

APPENDIX A

                            IRA DISCLOSURE STATEMENT

This statement is designed to help you understand the requirements of federal
tax law which apply to your individual retirement annuity (IRA), your Roth IRA,
your simplified employee pension IRA (SEPP-IRA) for employer contributions, your
Savings Incentive Match Plan for Employees (SIMPLE) IRA, or to one you purchase
for your spouse. You can obtain more information regarding your IRA either from
your sales representative or from any district office of the Internal Revenue
Service.

FREE LOOK PERIOD

The annuity contract offered by this prospectus gives you the opportunity to
return the contract for a full refund within 10 days after it is delivered. This
is a more liberal provision than is required in connection with IRAs. To
exercise this "free-look" provision write or call the address shown below:

The Ohio National Life Insurance Company Variable Annuity Administration P. O.
Box 2669 Cincinnati, Ohio 45201 Telephone: 1-800-366-6654 -- 8:30 a.m. - 4:30
p.m. (Eastern time zone)

ELIGIBILITY REQUIREMENTS

IRAs are intended for all persons with earned compensation whether or not they
are covered under other retirement programs. Additionally if you have a
non-working spouse (and you file a joint tax return), you may establish an IRA
on behalf of your non-working spouse. A working spouse may establish his or her
own IRA.
A divorced spouse receiving taxable alimony (and no other income) may also
establish an IRA.

CONTRIBUTIONS AND DEDUCTIONS

Contributions to your IRA will be deductible if you are not an "active
participant" in an employer maintained qualified retirement plan or you have
Adjusted Gross Income which does not exceed the "applicable dollar limit". IRA
(or SEPP-IRA) contributions must be made by no later than the time you file your
income tax return for that year. For a single taxpayer, the applicable dollar
limitation is $30,000, with the amount of IRA contribution which may be deducted
reduced proportionately for Adjusted Gross Income between $30,000-$40,000. For
married couples filing jointly, the applicable dollar limitation is $50,000,
with the amount of IRA contribution which may be deducted reduced
proportionately for Adjusted Gross Income between $50,000-$60,000. There is no
deduction allowed for IRA contributions when Adjusted Gross Income reaches
$40,000 for individuals and $60,000 for married couples filing jointly.

Contributions made by your employer to your SEPP-IRA are excludable from your
gross income for tax purposes in the calendar year for which the amount is
contributed. Certain employees who participate in a SEPP-IRA will be entitled to
elect to have their employer make contributions to their SEPP-IRA on their
behalf or to receive the contributions in cash. If the employee elects to have
contributions made on the employee's behalf to the SEPP, those funds are not
treated as current taxable income to the employee. Elective deferrals under a
SEPP-IRA are subject to an inflation-adjusted limit which is $10,000 for 1998.
Salary-reduction SEPP-IRAs (also called "SARSEPs") are available only if at
least 50% of the employees elect to have amounts contributed to the SEPP-IRA and
if the employer has 25 or fewer employees at all times during the preceding
year. New salary-reduction SEPPs may not be established after 1996.

The IRA maximum annual contribution and your tax deduction is limited to the
lesser of: (1) $2,000 or (2) 100% of your earned compensation. Contributions in
excess of the deduction limits may be subject to penalty. See below.

Under a SEPP-IRA agreement, the maximum annual contribution which your employer
may make on your behalf to a SEPP-IRA contract which is excludable from your
income is the lesser of 15% of your salary or $24,000. An employee who is a
participant in a SEPP-IRA agreement may make after-tax contributions to the
SEPP-IRA

Form 8523

                                       25
<PAGE>   30

contract, subject to the contribution limits applicable to IRAs in general.
Those employee contributions will be deductible subject to the deductibility
rules described above.

The maximum tax deductible annual contribution that a divorced spouse with no
other income may make to an IRA is the lesser of (1) $2,000 or (2) 100% of
taxable alimony.

If you or your employer should contribute more than the maximum contribution
amount to your IRA or SEPP-IRA, the excess amount will be considered an "excess
contribution". You are permitted to withdraw an excess contribution from your
IRA or SEPP-IRA before your tax filing date without adverse tax consequences.
If, however, you fail to withdraw any such excess contribution before your tax
filing date, a 6% excise tax will be imposed on the excess for the tax year of
contribution.

Once the 6% excise tax has been imposed, an additional 6% penalty for the
following tax year can be avoided if the excess is (1) withdrawn before the end
of the following year, or (2) treated as a current contribution for the
following year. (See Premature Distributions for penalties imposed on withdrawal
when the contribution exceeds $2,000).

IRA FOR NON-WORKING SPOUSE

If you establish an IRA for yourself, you may also be eligible to establish an
IRA for your "non-working" spouse. In order to be eligible to establish such a
spousal IRA, you must file a joint tax return with your spouse and if your
non-working spouse has compensation, his/her compensation must be less than your
compensation for the year. Contributions of up to $2,000 each may be made to
your IRA and the spousal IRA if the combined compensation of you and your spouse
is at least equal to the amount contributed. If requirements for deductibility
(including income levels) are met, you will be able to deduct an amount equal to
the least of (i) the amount contributed to the IRA's; (ii) $4,000; or (iii) 100%
of your combined gross income.

Contributions in excess of the contribution limits may be subject to penalty.
See above under "Contributions and Deductions". If you contribute more than the
allowable amount, the excess portion will be considered an excess contribution.
The rules for correcting it are the same as discussed above for regular IRAs.

Other than the items mentioned in this section, all of the requirements
generally applicable to IRAs are also applicable to IRAs established for
non-working spouses.

ROLLOVER CONTRIBUTION

Once every year, you are permitted to withdraw any portion of the value of your
IRA or SEPP-IRA and reinvest it in another IRA or bond. Withdrawals may also be
made from other IRAs and contributed to this contract. This transfer of funds
from one IRA to another is called a "rollover" IRA. To qualify as a rollover
contribution, the entire portion of the withdrawal must be reinvested in another
IRA within 60 days after the date it is received. You will not be allowed a
tax-deduction for the amount of any rollover contribution.

A similar type of rollover to an IRA can be made with the proceeds of a
qualified distribution from a qualified retirement plan or tax-sheltered
annuity. Properly made, such a distribution will not be taxable until you
receive payments from the IRA created with it. Unless you were a self-employed
participant in the distributing plan, you may later roll over such a
contribution to another qualified retirement plan as long as you have not mixed
it with IRA (or SEPP-IRA) contributions you have deducted from your income. (You
may roll less than all of a qualified distribution into an IRA, but any part of
it not rolled over will be currently includable in your income without any
capital gains treatment.)

PREMATURE DISTRIBUTIONS

At no time can your interest in your IRA or SEPP-IRA be forfeited. To insure
that your contributions will be used for your retirement, the federal tax law
does not permit you to use your IRA or SEPP-IRA as security for a loan.
Furthermore, as a general rule, you may not sell or assign your interest in your
IRA or SEPP-IRA to anyone. Use of an IRA (or SEPP-IRA) as security or assignment
of it to another will invalidate the entire annuity.

Form 8523

                                       26
<PAGE>   31

It then will be includable in your income in the year it is invalidated and will
be subject to a 10% penalty tax if you are not at least age 59 1/2 or totally
disabled. (You may, however, assign your IRA or SEPP-IRA without penalty to your
former spouse in accordance with the terms of a divorce decree.)

You may surrender any portion of the value of your IRA (or SEPP-IRA). In the
case of a partial surrender which does not qualify as a rollover, the amount
withdrawn will be includable in your income and subject to the 10% penalty if
you are not at least age or 59 1/2 totally disabled unless you comply with
special rules requiring distributions to be made at least annually over your
life expectancy.

The 10% penalty tax does not apply to the withdrawal of an excess contribution
as long as the excess is withdrawn before the due date of your tax return.
Withdrawals of excess contributions after the due date of your tax return will
generally be subject to the 10% penalty unless the excess contribution results
from erroneous information from a plan trustee making an excess rollover
contribution or unless you are over age 59 1/2 or are disabled.

DISTRIBUTION AT RETIREMENT

Once you have attained age 59 1/2 (or have become totally disabled), you may
elect to receive a distribution of your IRA (or SEPP-IRA) regardless of when you
actually retire. You may elect to receive the distribution in either one sum or
under any one of the periodic payment options available under the contract. The
distributions from your IRA under any one of the periodic payment options or in
one sum will be treated as ordinary income as you receive them.

INADEQUATE DISTRIBUTIONS -- 50% TAX

Your IRA or SEPP-IRA is intended to provide retirement benefits over your
lifetime. Thus, federal law requires that you either (1) receive a lump-sum
distribution of your IRA by April 1 of the year following the year in which you
attain age 70 or (2) start to receive periodic payments by that date. If you
elect to receive periodic payments, those payments must be sufficient to pay out
the entire value of your IRA during your life expectancy (or over the joint life
expectancies of you and your spouse). If the payments are not sufficient to meet
these requirements, an excise tax of 50% will be imposed on the amount of any
underpayment.


DEATH BENEFITS


If you, (or your surviving spouse) die before receiving the entire value of your
IRA (or SEPP-IRA), the remaining interest must be distributed to your
beneficiary (or your surviving spouse's beneficiary) in one lump-sum within 5
years of death, or applied to purchase an immediate annuity for the beneficiary.
This annuity must be payable over the life expectancy of the beneficiary
beginning within one year after your or your spouse's death. If your spouse is
the designated beneficiary, he or she is treated as the owner of the IRA. If
minimum required distributions have begun, the entire amount must be distributed
at least as rapidly as if the owner had survived. A distribution of the balance
of your IRA upon your death will not be considered a gift for federal tax
purposes, but will be included in your gross estate for purposes of federal
estate taxes.


ROTH IRAS


Section 408A of the Code permits eligible individuals to contribute to a type of
IRA known as a "Roth IRA." Contributions may be made to a Roth IRA by taxpayers
with adjusted gross incomes of less than $160,000 for married individuals filing
jointly and less than $100,000 for single individuals. Married individuals
filing separately are not eligible to contribute to a Roth IRA. The maximum
amount of contributions allowable for any taxable year to all Roth IRAs
maintained by an individual is generally the lesser of $2,000 and 100% of
compensation for that year (the $2,000 limit is phased out for incomes between
$150,000 and $160,000 for married and between $95,000 and $110,000 for singles).
The contribution limit is reduced by the amount of any contributions made to a
non-Roth IRA. Contributions to a Roth IRA are not deductible.

Form 8523

                                       27
<PAGE>   32

For taxpayers with adjusted gross income of $100,000 or less, all or part of
amounts in a non-Roth IRA may be converted, transferred or rolled over to a Roth
IRA. Some or all of the IRA value will typically be includable in the taxpayer's
gross income. If such a rollover, transfer or conversion occurred before 1/1/99,
the portion of the amount includable in gross income must be included in income
ratably over the next four years beginning with the year in which the
transaction occurred. Provided a rollover contribution meets the requirements
for IRAs under Section 408(d)(3) of the Code, a rollover may be made from a Roth
IRA to another Roth IRA.

UNDER SOME CIRCUMSTANCES, IT MAY NOT BE ADVISABLE TO ROLL OVER, TRANSFER OR
CONVERT ALL OR PART OF A NON-ROTH IRA TO A ROTH IRA. PERSONS CONSIDERING A
ROLLOVER, TRANSFER OR CONVERSION SHOULD CONSULT THEIR OWN TAX ADVISOR.

"Qualified distributions" from a Roth IRA are excludable from gross income. A
"qualified distribution" is a distribution that satisfies two requirements: (1)
the distribution must be made (a) after the owner of the IRA attains age 59 1/2;
(b) after the owner's death; (c) due to the owner's disability; or (d) for a
qualified first time homebuyer distribution within the meaning of Section
72(t)(2)(F) of the Code; and (2) the distribution must be made in the year that
is at least five years after the first year for which a contribution was made to
any Roth IRA established for the owner or five years after a rollover, transfer
or conversion was made from a non-Roth IRA to a Roth IRA. Distributions from a
Roth IRA that are not qualified distributions will be treated as made first from
contributions and then from earnings, and taxed generally in the same manner as
distributions from a non-Roth IRA.

Distributions from a Roth IRA need not commence at age 70 1/2. However, if the
owner dies before the entire interest in a Roth IRA is distributed, any
remaining interest in the contract must be distributed by December 31 of the
calendar year containing the fifth anniversary of the owner's death subject to
certain exceptions.


PROTOTYPE STATUS


The Internal Revenue Service has been requested to review the format of your
SEPP, and to issue an opinion letter to Ohio National Life stating that your IRA
qualifies as a prototype SEPP.


REPORTING TO THE IRS


Whenever you are liable for one of the penalty taxes discussed above (6% for
excess contributions, 10% for premature distributions or 50% for underpayments),
you must file Form 5329 with the Internal Revenue Service. The form is to be
attached to your federal income tax return for the tax year in which the penalty
applies. Normal contributions and distributions must be shown on your income tax
return for the year to which they relate.

This prospectus offers a variable annuity contract allowing you to accumulate
values and paying you benefits on a variable and/or fixed basis.

Variable annuities provide contract values and lifetime annuity payments that
vary with the investment results of the Funds you choose. You cannot be sure
that the contract value or annuity payments will equal or exceed your purchase
payments.

The variable annuity contracts are designed for:

- - annuity purchase plans adopted by public school systems and certain tax-exempt
  organizations described in Section 501(c)(3) of the Internal Revenue Code (the
  "Code"), qualifying for tax-deferred treatment pursuant to Section 403(b) of
  the Code,

- - other employee pension or profit-sharing trusts or plans qualifying for
  tax-deferred treatment under Section 401(a), 401(k) or 403(a) of the Code,

- - individual retirement annuities qualifying for tax-deferred treatment under
  Section 408 or 408A of the Code, (4) state and municipal deferred compensation
  plans and

- - non-tax-qualified retirement plans.

The minimum initial purchase payment is $10,000. You may make additional
payments of at least $500 at any time ($300 for payroll deduction plans). We may
limit your total purchase payments to $1,500,000.


You may direct the allocation of your purchase payments to one or more (but not
more than 10) subaccounts of Ohio National Variable Account A ("VAA") and/or the
Guaranteed Account. VAA is a separate account of The Ohio National Life
Insurance Company. The assets of VAA are invested in shares of the Funds. The
Funds are portfolios of Ohio National Fund, Inc., the Dow Target Variable Fund
LLC, Goldman Sachs Variable Insurance Trust, Janus Aspen Series, J.P. Morgan
Series Trust II, Lazard Retirement Series, Inc., PBHG Insurance Series Fund,
Inc., The Prudential Series Fund, Inc., Salomon Brothers Variable Series Funds
Inc, Strong Variable Insurance Funds, Inc. and Variable Insurance Products Fund
(Fidelity). See page 2 for the list of available Funds. See also the
accompanying prospectuses of the Funds. The Fund prospectuses might also contain
information about funds that are not available for these contracts.



You may withdraw all or part of the contract's value before annuity payments
begin. You might incur federal income tax penalties for these early withdrawals.
Your exercise of contract rights may be subject to the terms of your qualified
employee trust or annuity plan. This prospectus contains no information
concerning your trust or plan. The prospectus does not provide details of all
our administrative policies and procedures.


You may revoke the contract, without penalty, within 10 days of receiving it (or
a longer period if required by state law).

VAA AND THE VARIABLE ANNUITY CONTRACTS THAT YOU SHOULD KNOW BEFORE INVESTING.

These fees do not exceed 0.25%. Note that the expense amounts shown in the
examples are aggregate amounts for the total number of years indicated. In the
examples, the annual fee is treated as if it were deducted as a percentage of
assets, based upon the average account value for all contracts, including ones
from which a portion of the contract fee may be paid from amounts invested in
the Guaranteed Account. The above table and examples reflect only the charges
for contracts currently offered by this prospectus and not other contracts that
we may offer.

OHIO NATIONAL LIFE



Ohio National Life was organized under the laws of Ohio on September 9, 1909. We
write life, accident and health insurance and annuities in 47 states, the
District of Columbia and Puerto Rico. Currently we have assets in excess of $7.6
billion and equity in excess of $725 million. Our home office is located at One
Financial Way, Montgomery, Ohio 45242. We are a stock life insurance company
ultimately owned by a mutual insurance holding company (Ohio National Mutual
Holdings, Inc.). Our policyholders own the majority voting interest of the
holding company.


OHIO NATIONAL VARIABLE ACCOUNT A

We established VAA on August 1, 1969 as a separate account for funding variable
annuity contracts. Purchase payments for the variable annuity contracts are
allocated to one or more subaccounts of VAA. However, contract values may not be
allocated to more than 10 variable subaccounts at any one time. Income, gains
and losses, whether or not realized, from assets allocated to VAA are credited
to or charged against VAA without regard to our other income, gains or losses.
The assets maintained in VAA will not be charged with any liabilities arising
out of any of our other business. Nevertheless, all obligations arising under
the contracts, including the commitment to make annuity payments, are our
general corporate obligations. Accordingly, all our assets are available to meet
our obligations under the contracts. VAA is registered as a unit investment
trust under the

Form 8902

                                       10
<PAGE>   45

Investment Company Act of 1940. The assets of the subaccounts of VAA are
invested at net asset value in Fund shares. Values of other contracts not
offered through this prospectus are also allocated to VAA, including some
subaccounts that are not available for these contracts.

THE FUNDS

The Funds are mutual funds registered under the Investment Company Act 1940.
Fund shares are sold only to insurance company separate accounts to fund
variable annuity contracts and variable life insurance policies and, in some
cases, to qualified plans. The value of each Fund's investments fluctuates daily
and is subject to the risk that Fund management may not anticipate or make
changes necessary in the investments to meet changes in economic conditions.

The Funds receive investment advice from their investment advisers. The Funds
pay each of the investment advisers a fee as shown in the fee table beginning on
page 4. In some cases, the investment adviser pays part of its fee to a
subadviser.

Affiliates of certain Funds may compensate us based upon a percentage of the
Fund's average daily net assets that are allocated to VAA. These percentages
vary by Fund. This is intended to compensate us for administrative and other
services we provide to the Funds and their affiliates.

For additional information concerning the Funds, including their investment
objectives, see the Fund prospectuses. Read them carefully before investing.
They may contain information about other funds that are not available as
investment options for these contracts. You cannot be sure that any Fund will
achieve its stated objectives and policies.

The investment policies, objectives and/or names of some of the Funds may be
similar to those of other investment companies managed by the same investment
adviser or subadviser. However, similar funds often do not have comparable
investment performance. The investment results of the Funds may be higher or
lower than those of the other funds.

MIXED AND SHARED FUNDING

In addition to being offered to VAA, certain Fund shares are offered to our
other separate accounts for variable annuity contracts and a separate account of
Ohio National Life Assurance Corporation for variable life insurance contracts.
Fund shares may also be offered to other insurance company separate accounts and
qualified plans. It is conceivable that in the future it may become
disadvantageous for one or more of variable life and variable annuity separate
accounts, or separate accounts of other life insurance companies, and qualified
plans to invest in Fund shares. Although neither we nor any of the Funds
currently foresee any such disadvantage, the Board of Directors or Trustees of
each Fund will monitor events to identify any material conflict among different
types of owners and to determine if any action should be taken. That could
possibly include the withdrawal of VAA's participation in a Fund. Material
conflicts could result from such things as:

- - changes in state insurance law;

- - changes in federal income tax law;

- - changes in the investment management of any Fund; or

- - differences in voting instructions given by different types of owners.

VOTING RIGHTS

We will vote Fund shares held in VAA at Fund shareholders meetings in accordance
with voting instructions received from contract owners. We will determine the
number of Fund shares for which you are entitled to give instructions as
described below. This determination will be within 90 days before the
shareholders meeting. Proxy material and forms for giving voting instructions
will be distributed to each owner. We will vote Fund shares held in VAA, for
which no timely instructions are received, in proportion to the instructions
that we do receive.

Form 8902

                                       11
<PAGE>   46

Until annuity payments begin, the number of Fund shares for which you may
instruct us is determined by dividing your contract value in each Fund by the
net asset value of a share of that Fund as of the same date. After annuity
payments begin, the number of Fund shares for which you may instruct us is
determined by dividing the actuarial liability for your variable annuity by the
net asset value of a Fund share as of the same date. Generally, the number of
votes tends to decrease as annuity payments progress.

                   DISTRIBUTION OF VARIABLE ANNUITY CONTRACTS

The variable annuity contracts are sold by our insurance agents who are also
registered representatives of broker-dealers that have entered into distribution
agreements with Ohio National Equities, Inc. "ONEQ" is a wholly-owned subsidiary
of ours. ONEQ is the principal underwriter of the contracts. ONEQ and the
broker-dealers are registered under the Securities Exchange Act of 1934 and are
members of the National Association of Securities Dealers, Inc. We pay ONEQ
7.25% of each purchase payment and ONEQ then pays part of that to the broker-
dealers. The broker-dealers pay their registered representatives from their own
funds. Purchase payments on which nothing is paid to registered representatives
may not be included in amounts on which we pay the sales compensation to ONEQ.
If our surrender charge is not sufficient to recover the fee paid to ONEQ, any
deficiency will be made up from our general assets. These include, among other
things, any profit from the mortality and expense risk charges. ONEQ's address
is One Financial Way, Montgomery, Ohio 45242.

                            DEDUCTIONS AND EXPENSES

SALES CHARGE

No deduction is made for sales expense.

CONTRACT ADMINISTRATION CHARGE

Each year on the contract anniversary (or when you surrender of the contract),
we will deduct a contract administration charge of $30 from the contract value.
This helps to repay us for maintaining the contract. There is no contract
administration charge for contracts having a value of at least $50,000. There is
no charge after annuity payments begin. We guarantee not to increase the
contract administration charge.

DEDUCTION FOR ADMINISTRATIVE EXPENSES

At the end of each valuation period we deduct an amount equal to 0.25% on an
annual basis of the contract value. This deduction reimburses us for expenses
not covered by the contract administration charge. Examples of these expenses
are accounting, auditing, legal, contract owner services, reports to regulatory
authorities and contract owners, contract issue, etc.

DEDUCTION FOR RISK UNDERTAKINGS

We guarantee that, until annuity payments begin, the contract's value will not
be affected by any excess of sales and administrative expenses over the
deductions for them. We also guarantee to pay a death benefit if the annuitant
dies before annuity payments begin. After annuity payments begin, we guarantee
that variable annuity payments will not be affected by adverse mortality
experience or expenses.

For assuming these risks, when we determine the accumulation unit values and the
annuity unit values for each subaccount, we make a deduction from the applicable
investment results equal to 1.25% of the contract value on an annual basis. We
may decrease that deduction at any time and we may increase it not more often
than annually to not more than 1.25% on an annual basis. We agree that the
deduction for these risk undertakings shall not be increased to more than the
rate in effect at the time the contract is issued. We may discontinue this
limitation on our right to increase the deduction, but only as to contracts
purchased after notice of the discontinuance. The risk charge is an indivisible
whole of the amount currently being deducted. However, we believe that a
reasonable allocation would be 0.65% for mortality risk, and 0.60% for expense
risk. We hope to

Form 8902

                                       12
<PAGE>   47

realize a profit from this charge. However there will be a loss if the deduction
fails to cover the actual risks involved.

TRANSFER FEE

We may charge a transfer fee of $10 for each transfer from one or more
subaccounts to other subaccounts. The fee is charged pro rata against the
subaccounts from which the transfer is made. We do not charge for your first
transfer each calendar month.

DEDUCTION FOR STATE PREMIUM TAX

Most states do not presently charge a premium tax for these contracts. Where a
tax applies, the rates for tax-qualified contracts are presently 0.5% in
California, 1.0% in Puerto Rico and West Virginia, 2.0% in Kentucky and 2.25% in
the District of Columbia. For non-tax-qualified contracts, the rates are
presently 1.0% in Puerto Rico, West Virginia and Wyoming, 1.25% in the South
Dakota, 2.0% in Kansas, Kentucky and Maine, 2.25% in the District of Columbia,
2.35% in California and 3.5% in Nevada. The deduction for premium taxes will be
made when incurred. Normally, that is not until annuity payments begin. However,
in Kansas, South Dakota and Wyoming, they are presently being deducted from
purchase payments.

FUND EXPENSES

There are deductions from, and expenses paid out of, the assets of the Funds.
These are described in the Fund prospectuses.

                   DESCRIPTION OF VARIABLE ANNUITY CONTRACTS

10-DAY FREE LOOK

You may revoke the contract at any time until the end of 10 days after you
receive it (or such longer period as may be required by your state law) and get
a refund of the contract value as of the date of cancellation. To revoke, you
must return the contract to us within the free look period. In Georgia, Idaho,
Indiana, Nebraska, Nevada, North Carolina, Oklahoma, South Carolina, Utah and
Washington, state law requires that the original purchase price be returned in
lieu of the current contract value if you exercise your free look. Any purchase
payments in these states to be allocated to variable Funds will first be
allocated to the Money Market Fund until the end of the free look period.

                              ACCUMULATION PERIOD

PURCHASE PAYMENTS


Your first purchase payment must be at least $10,000. You do not have to make
any more payments after that. But you may make additional purchase payments at
any time of at least $500 each ($300 for payroll deduction plans). We may limit
your total purchase payments to $1,500,000.


ACCUMULATION UNITS

Until the annuity payout date, the contract value is measured by accumulation
units. As you make each purchase payment, we credit units to the contract (see
Crediting Accumulation Units). The number of units remains constant between
purchase payments but their dollar value varies depending upon the investment
results of each Fund to which payments are allocated.

CREDITING ACCUMULATION UNITS

Your representative will send an order or application, together with the first
purchase payment, to our home office for acceptance. Upon acceptance, we issue a
contract and we credit the first purchase payment to the contract in the form of
accumulation units. If all information necessary for issuing a contract and
processing the purchase

Form 8902

                                       13
<PAGE>   48

payment is complete, we will credit your first purchase payment within two
business days after receipt. If we do not receive everything within five
business days, we will return the purchase payment to you immediately unless you
specifically consent to having us retain the purchase payment until the
necessary information is completed. After that, we will credit the purchase
payment within two business days.

You must send any additional purchase payments directly to our home office. They
will then be applied to provide that number of accumulation units (for each
subaccount) determined by dividing the amount of the purchase payment by the
unit value next computed after we receive the payment at our home office.

ALLOCATION OF PURCHASE PAYMENTS

You may allocate your purchase payments among up to 10 variable subaccounts of
VAA and to the Guaranteed Account. The amount you allocate to any Fund or the
Guaranteed Account must equal a whole percent You may change your allocation of
future purchase payments at any time by sending written notice to our home
office.

ACCUMULATION UNIT VALUE AND ACCUMULATION VALUE

We set the accumulation unit value of each subaccount of VAA at $10 when we
credited the first payments for these contracts. We determine the unit value for
any later valuation period by multiplying the unit value for the immediately
preceding valuation period by the net investment factor (described below) for
such later valuation period. We determine a contract's value by multiplying the
total number of units (for each subaccount) credited to the contract by the unit
value (for such subaccount) for the current valuation period.

NET INVESTMENT FACTOR

The net investment factor measures the investment results of each subaccount.
The net investment factor for each subaccount for any valuation period is
determined by dividing (a) by (b), then subtracting (c) from the result, where:

(a) is

     (1) the net asset value of the corresponding Fund share at the end of a
         valuation period, plus

     (2) the per share amount of any dividends or other distributions declared
         for that Fund if the "ex-dividend" date occurs during the valuation
         period, plus or minus

     (3) a per share charge or credit for any taxes paid or reserved for the
         maintenance or operation of that subaccount; (No federal income taxes
         apply under present law.)

(b) is the net asset value of the corresponding Fund share at the end of the
    preceding valuation period; and

(c) is the deduction for administrative and sales expenses and risk
    undertakings.

SURRENDER AND PARTIAL WITHDRAWAL

Before annuity payments begin (and also after that in the case of annuity Option
1(e) described below) you may surrender (totally withdraw the value of) your
contract or elect a partial withdrawal (at least $1,000). In the case of a
complete surrender, we subtract any contract administration charge. We will pay
you within seven days after we receive your request. However, we may defer
payment described below. Surrenders and partial withdrawals are limited or not
permitted in connection with certain retirement plans. For tax consequences of a
surrender or withdrawal, see Federal Tax Status.

If you request a surrender or partial withdrawal which includes contract values
derived from purchase payments that have not yet cleared the banking system, we
may delay mailing the portion relating to such payments until your check has
cleared. We require the return of the contract in the case of a complete
surrender.

Form 8902

                                       14
<PAGE>   49

Your right to withdraw may be suspended or the date of payment postponed:

(1) for any period during which the New York Stock Exchange is closed (other
than customary weekend and holiday closings) or during which the Securities and
Exchange Commission has restricted trading on the Exchange;

(2) for any period during which an emergency, as determined by the Commission,
exists as a result of which disposal of securities held in a Fund is not
reasonably practical, or it is not reasonably practical to determine the value
of a Fund's net assets; or

(3) such other periods as the Commission may order to protect security holders.

TRANSFERS AMONG SUBACCOUNTS

You may transfer contract values from one or more Funds to one or more other
Funds. You may make transfers at any time before annuity payments begin. The
amount of any transfer must be at least $300 (or the entire value of the
contract's interest in a Fund, if less).

We may limit the number, frequency, method or amount of transfers. We may limit
transfers from any Fund on any one day to 1% of the previous day's total net
assets of that Fund if we or the Fund in our discretion, believe that the Fund
might otherwise be damaged. In determining which requests to honor, scheduled
transfers (under a DCA program) will be made first, followed by mailed written
requests in the order postmarked and, lastly, telephone and facsimile requests
in the order received. We will notify you if your requested transfer is not
made. Current SEC rules preclude us from processing at a later date those
requests that were not made. Accordingly, you would need to submit a new
transfer request in order to make a transfer that was not made because of these
limitations.

Certain third parties may offer you asset allocation or timing services for your
contract. We may choose to honor transfer requests from these third parties if
you give us a written power of attorney to do so. Fees you pay for such asset
allocation or timing services are in addition to any contract charges. WE DO NOT
ENDORSE, APPROVE OR RECOMMEND THESE SERVICES.

After annuity payments begin, you may make transfers among Funds only once each
calendar quarter. The transfer fee no longer applies then. Not more than 20% of
a contract's Guaranteed Account value (or $1,000, if greater) as of the
beginning of a contract year may be transferred to variable Funds during that
contract year.

TELEACCESS

If you give us a pre-authorization form, your contract and unit values and
interest rates can be checked and transfers may be made by telephoning us
between 7:00 a.m. and 7:00 p.m. (Eastern time) on days that we are open for
business, at 1-800-366-6654, #8. You may only make one telephone transfer per
day. We will honor pre-authorized telephone transfer instructions from anyone
who provides the personal identifying information requested via TeleAccess. We
will not honor telephone transfer requests after we receive notice of your
death. For added security, we send the contract owner a written confirmation of
all telephone transfers on the next business day. However, if we cannot complete
a transfer as requested, our customer service representative will contact the
owner in writing sent within 48 hours of the TeleAccess request. YOU MAY THINK
THAT YOU HAVE LIMITED THIS ACCESS TO YOURSELF, OR TO YOURSELF AND YOUR
REPRESENTATIVE. HOWEVER, ANYONE GIVING US THE NECESSARY IDENTIFYING INFORMATION
CAN USE TELEACCESS ONCE YOU AUTHORIZE IT.

SCHEDULED TRANSFERS (DOLLAR COST AVERAGING)

We administer a scheduled transfer ("DCA") program enabling you to preauthorize
automatic monthly or quarterly transfers of a specified dollar amount of at
least $300 each time. At least 12 DCA transfers must be scheduled. The transfers
may be from any variable Funds to any other Funds or to the Guaranteed Account.
Transfers may be made from the Guaranteed Account to any other Funds if the DCA
program is established at the time the contract is issued, the DCA program is
scheduled to begin within 6 months of contract issue and

Form 8902

                                       15
<PAGE>   50

the term of the DCA program does not exceed 2 years. For transfers from variable
Funds, the DCA program may not exceed 5 years. There is no transfer fee for DCA
transfers. DCA transfers do not count as the free transfer you are allowed once
each calendar month. We may discontinue the DCA program at any time. You may
also discontinue further DCA transfers by giving us written notice at least 7
business days before the next scheduled transfer.

DCA generally has the effect of reducing the risk of purchasing at the top, and
selling at the bottom, of market cycles. DCA transfers from the Guaranteed
Account or from a Fund with a stabilized net asset value, such as the Money
Market Fund, will generally reduce the average total cost of indirectly
purchasing Fund shares because greater numbers of shares will be purchased when
the share prices are lower than when prices are higher. However, DCA does not
assure you of a profit, nor does it protect against losses in a declining
market. Moreover, for transfers from a variable Fund, DCA has the effect of
reducing the average price of the shares being redeemed. DCA might also be used
to systematically transfer contract values from variable Funds to the Guaranteed
Account in anticipation of retirement, reducing the risk of making a single
transfer during a low market.

PORTFOLIO REBALANCING

You may have us automatically transfer amounts on a quarterly, semi-annual or
annual basis to maintain a specified percentage (whole percentages only) of
contract value in each of two or more designated Funds. The purpose of a
portfolio rebalancing strategy is to maintain, over time, your desired
allocation percentage in the designated Funds having differing investment
performance. Portfolio rebalancing will not necessarily enhance future
performance or protect against future losses.


To elect, change or discontinue this option, you must give us written
authorization. The transfer charge does not apply to portfolio rebalancing
transactions. These transactions do not count against the free transfer you are
allowed once each calendar month. You may not have portfolio rebalancing for any
Funds that are part of a DCA program.


DEATH BENEFIT

If the annuitant (and any contingent annuitant) dies before annuity payments
begin, the contract pays a death benefit to a designated beneficiary. (Death
benefits are not available on any contract purchased through a bank in Puerto
Rico.) The amount of the death benefit will be determined as of the date of the
annuitant's death. It will be paid to the beneficiary in a single sum unless you
elect settlement under one or more of the settlement options. If the death
benefit is not claimed within 90 days after the date of death, we will pay the
contract value instead of any greater death benefit.

This death benefit will be the greater of:

- - the contract value; or

- - the net of purchase payments less withdrawals.

In those states where permitted, you may elect an optional annual stepped-up
death benefit at the time the contract is issued. With that option, the death
benefit on the first contract anniversary will be the greater of (a) the
contract value then or (b) the net of purchase payments minus withdrawals made
on or before that date. On each contract anniversary after that (until the
annuitant attains age 80), the death benefit will be reset to the greater of (a)
the contract value on that anniversary date or (b) the death benefit as of the
last preceding anniversary. The death benefit is increased by purchase payments
and decreased by withdrawals made during the year before each anniversary. There
is an additional charge (presently at an annual rate of 0.05% of the optional
death benefit amount, which rate may be increased to no more than 0.25% on
contracts issued in the future) for this optional benefit.

In those states where permitted, you may elect a guaranteed minimum death
benefit at the time the contract is issued. With this option, the death benefit
is the greater of (a) the contract value on the date of death or (b) the

Form 8902

                                       16
<PAGE>   51

guaranteed minimum death benefit amount. The guaranteed minimum death benefit
amount for contract values held in the Guaranteed Account and the Money Market
Fund is the contract value as of the date of death. For all other subaccounts,
the guaranteed minimum death benefit amount is (i) the net of purchase payments
less withdrawals plus (ii) a daily increase, until the annuitant attains age 80,
at an effective annual rate of 6%. There is an additional charge for this option
of 0.25% of the guaranteed minimum death benefit amount.

GUARANTEED ACCOUNT

The Guaranteed Account guarantees a fixed return for a specified period of time
and guarantees the principal against loss. The Guaranteed Account is not
registered as an investment company. Interests in it are not subject to the
provisions or restrictions of federal securities laws. The staff of the
Securities and Exchange Commission has not reviewed disclosures regarding it.

The Guaranteed Account consists of all of our general assets other than those
allocated to a separate account. You may allocate purchase payments and contract
values between the Guaranteed Account and the Funds.

We invest our general assets in our discretion as allowed by Ohio law. We
allocate the investment income from our general assets to those contracts having
guaranteed values.

The amount of investment income allocated to the contracts varies from year to
year in our sole discretion. However, we guarantee that we will credit interest
at a rate of not less than 3% per year, compounded annually, to contract values
allocated to the Guaranteed Account. We may credit interest at a rate in excess
of 3%, but any such excess interest credit will be in our sole discretion.

We guarantee that, before annuity payments begin, the guaranteed value of a
contract will never be less than:

- - the amount of purchase payments allocated to, and transfers into, the
  Guaranteed Account, plus

- - interest credited at the rate of 3% per year compounded annually, plus

- - any additional excess interest we may credit to guaranteed values, minus

- - any partial withdrawals, loans and transfers from the guaranteed values, minus

- - any loan interest, state premium taxes, transfer fees, and the portion of the
  $30 annual contract administration charge allocable to the Guaranteed Account.

No deductions are made from the Guaranteed Account for administrative expenses
or risk undertakings.

Other than pursuant to a DCA (scheduled transfer) or portfolio rebalancing
program, we may restrict transfers of your Guaranteed Account value during a
contract year to not more than 20% of that value as of the beginning of a
contract year (or $1,000, if greater). As provided by state law, we may defer
the payment of amounts to be withdrawn from the Guaranteed Account for up to six
months from the date we receive your written request for withdrawal.

OHIO NATIONAL LIFE EMPLOYEE DISCOUNT

We and our affiliated companies offer a credit on the purchase of contracts by
any of our employees, directors or retirees, or their spouse or the surviving
spouse of a deceased retiree, their minor children, or any of their children
ages 18 to 21 who is either (i) living in the purchaser's household or (ii) a
full-time college student being supported by the purchaser, or any of the
purchaser's minor grandchildren under the Uniform Gifts to Minors Act. This
credit counts as additional income under the contract. The amount of the credit
equals 3.2% of all purchase payments made in the first contract year and 5.5% of
purchase payments made in the second through sixth contract years. We credit the
Guaranteed Account in these amounts at the time the eligible person makes each
payment.

TEXAS STATE OPTIONAL RETIREMENT PROGRAM

Under the Texas State Optional Retirement Program (the "Program"), purchase
payments may be excluded from the gross income of state employees for federal
tax purposes to the extent that such purchase payments do not exceed the
exclusion allowance provided by the Code. The Attorney General of Texas has
interpreted the Program as prohibiting any participating state employee from
receiving the surrender value of a contract funding benefits under the Program
prior to termination of employment or the state employee's retirement, death or
total disability. Therefore, a participant in the Program may not make a
surrender or partial withdrawal until the first of these events occurs.

                                 ANNUITY PERIOD

ANNUITY PAYOUT DATE

Annuity payments begin on the annuity payout date. You may select this date when
the contract is issued. It must be at least 30 days after the contract date. You
may change it from time to time so long as it is the first day of any month at
least 30 days after the date of such change. The contract restricts the annuity
payout date to not later than the first of the month following the annuitant's
90th birthday. This restriction may be modified by applicable state law or we
may agree to waive it.

The contracts include our guarantee (except for option 1(e) below) that we will
pay annuity payments for the lifetime of the annuitant (and any joint annuitant)
in accordance with the contract's annuity rates, no matter how long you live.

Other than in connection with annuity Option 1(e) described below, once annuity
payments begin, you may not surrender the contract for cash except that, upon
the death of the annuitant, the beneficiary may surrender the contract for the
commuted value of any remaining period-certain payments. You may make surrenders
and partial withdrawals from Option 1(e) at any time.

ANNUITY OPTIONS

You may elect one or more of the following annuity options. You may change the
election anytime before the annuity payout date.

Option 1(a):   Life Annuity with installment payments for the lifetime of the
               annuitant. (The contract has no more value after the annuitant's
               death).

Option 1(b):  Life Annuity with installment payments guaranteed for five years
              and then continuing during the remaining lifetime of the
              annuitant.

Option 1(c):   Life Annuity with installment payments guaranteed for ten years
               and then continuing during the remaining lifetime of the
               annuitant.

Option 1(d):  Installment Refund Life Annuity with payments guaranteed for a
              period certain and then continuing during the remaining lifetime
              of the annuitant. The number of period-certain payments is equal
              to the amount applied under this option divided by the amount of
              the first payment.

Option 1(e):   Installment Refund Annuity with payments guaranteed for a fixed
               number (up to thirty) of years. This option is available for
               variable annuity payments only. (Although the deduction for risk
               undertakings is taken from annuity unit values, we have no
               mortality risk during the annuity payout period under this
               option.)

Option 2(a):   Joint & Survivor Life Annuity with installment payments during
               the lifetime of the annuitant and then continuing during the
               lifetime of a contingent annuitant. (The contract has no more
               value after the second annuitant's death.)

Form 8902

                                       18
<PAGE>   53

Option 2(b):  Joint & Survivor Life Annuity with installment payments guaranteed
              for ten years and then continuing during the remaining lifetime of
              the annuitant or a contingent annuitant.

We may agree to other settlement options.

Unless you direct otherwise, we will apply the contract value as of the annuity
payout date to provide annuity payments pro-rata from each Fund in the same
proportion as the contract values immediately before the annuity payout date.

If no election is in effect on the annuity payout date, we will apply contract
value under Option 1(c) with the beneficiary as payee for any remaining
period-certain installments payable after the death of the annuitant. The
Pension Reform Act of 1974 might require certain contracts to provide a Joint
and Survivor Annuity. If the contingent annuitant is not related to the
annuitant, Options 2(a) and 2(b) are available only if we agree.

The Internal Revenue Service has not ruled on the tax treatment of a commutable
variable annuity. If you select Option 1(e), it is possible that the IRS could
determine that the entire value of the annuity is fully taxable at the time you
elect Option 1(e) or that variable annuity payments under this option should not
be taxed under the annuity rules (see Federal Tax Status). This could result in
your payments being fully taxable to you. Should the IRS so rule, we may have to
tax report up to the full value of the annuity as your taxable income.

DETERMINATION OF AMOUNT OF THE FIRST VARIABLE ANNUITY PAYMENT

To determine the first variable annuity payment we apply the contract value for
each Fund in accordance with the contract's settlement option tables. The rates
in those tables depend upon the annuitant's (and any contingent annuitant's) age
and sex and the option selected. The annuitant's sex is not a factor in
contracts issued to plans sponsored by employers subject to Title VII of the
Civil Rights Act of 1964 or similar state statutes. We determine the value to be
applied at the end of a valuation period (selected by us and uniformly applied)
not more than 10 valuation periods before the annuity payout date.

If the amount that would be applied under an option is less than $5,000, we will
pay the contract value to the annuitant in a single sum. If the first periodic
payment under any option would be less than $25, we may change the frequency of
payments so that the first payment is at least $25.

ANNUITY UNITS AND VARIABLE PAYMENTS

After your first annuity payment, later variable annuity payments will vary to
reflect the investment performance of your Funds. The amount of each payment
depends on the number of your annuity units. To determine the number of annuity
units for each Fund, divide the dollar amount of the first annuity payment from
each Fund by the value that Fund's annuity unit. This number of annuity units
remains constant during the annuity payment period unless you transfer among
Funds.

The annuity unit value for each Fund was set at $10 for the valuation period
when the first variable annuity was calculated for these contracts. The annuity
unit value for each later valuation period equals the annuity unit value for the
immediately preceding valuation period multiplied by the net investment factor
(described on page 12) for such later valuation period and by a factor (0.999919
for a one-day valuation period) to neutralize the 3% assumed interest rate
discussed below.

The dollar amount of each later variable annuity payment equals your constant
number of annuity units for each Fund multiplied by the value of the annuity
unit for the valuation period.

The annuity rate tables contained in the contracts are based on the 1983(a)
Mortality Table Projected to 1996 under Scale G with compound interest at the
effective rate of 3% per year. A higher interest assumption would mean a higher
initial annuity payment but a more slowly rising series of subsequent annuity
payments if annuity unit values were increasing (or a more rapidly falling
series of subsequent annuity payments if annuity unit values were decreasing). A
lower interest assumption would have the opposite effect. If the actual net
investment rate were equal to the assumed interest rate, annuity payments would
stay level.

TRANSFERS DURING ANNUITY PAYOUT

After annuity payments have been made for at least 12 months, the annuitant can,
once each calendar quarter, change the Funds on which variable annuity payments
are based. On at least 30 days written notice our home office we will change
that portion of the periodic variable annuity payment as you direct to reflect
the investment results of different Funds. The annuity payment immediately after
a change will be the amount that would have been paid without the change. Later
payments will reflect the new mix of Funds.

                           OTHER CONTRACT PROVISIONS

ASSIGNMENT

Amounts payable in settlement of a contract may not be commuted, anticipated,
assigned or otherwise encumbered, or pledged as loan collateral to anyone other
than us. To the extent permitted by law, such amounts are not subject to any
legal process to pay any claims against an annuitant before annuity payments
begin. The owner of a tax-qualified contract may not, but the owner of a
non-tax-qualified contract may, collaterally assign the contract before the
annuity payout date. Ownership of a tax-qualified contract may not be
transferred except to:

- - the annuitant,

- - a trustee or successor trustee of a pension or profit-sharing trust which is
  qualified under Section 401 of the Code,

- - the employer of the annuitant provided that the contract after transfer is
  maintained under the terms of a retirement plan qualified under Section 403(a)
  of the Code for the benefit of the annuitant, or

- - as otherwise permitted by laws and regulations governing plans for which the
  contract may be issued.

PERIODIC REPORTS

Before the annuity payout date, we will send you quarterly statements showing
the number of units credited to the contract by Fund and the value of each unit
as of the end of the last quarter. In addition, as long as the contract remains
in effect, we will forward any periodic Fund reports.

SUBSTITUTION FOR FUND SHARES

If investment in a Fund is no longer possible or we believe it is inappropriate
to the purposes of the contract, we may substitute one or more other funds.
Substitution may be made as to both existing investments and the investment of
future purchase payments. However, no substitution will be made until we receive
any necessary approval of the Securities and Exchange Commission. We may also
add other Funds as eligible investments of VAA.

                            CONTRACT OWNER INQUIRIES

Direct any questions to Ohio National Life, Variable Annuity Administration,
P.O. Box 2669, Cincinnati, Ohio 45201; telephone 1-800-366-6654 (8:30 a.m. to
4:30 p.m., Eastern time).

PERFORMANCE DATA

We may advertise performance data for the various Funds showing the percentage
change in unit values based on the performance of the applicable Fund over a
period of time (usually a calendar year). We determine the percentage change by
dividing the increase (or decrease) in value for the unit by the unit value at
the beginning of the period. This percent reflects the deduction of any
asset-based contract but does not reflect the deduction of any applicable
contract administration charge or surrender charge. The deduction of a contract
administration charge or surrender charge would reduce any percentage increase
or make greater any percentage decrease.

Advertising may also include average annual total return figures calculated as
shown in the Statement of Additional Information. The average annual total
return figures reflect the deduction of applicable contract administration
charges and surrender charges as well as applicable asset-based charges.

We may also distribute sales literature comparing separate account performance
to the Consumer Price Index or to such established market indexes as the Dow
Jones Industrial Average, the Standard & Poor's 500 Stock Index, IBC's Money
Fund Reports, Lehman Brothers Bond Indices, the Morgan Stanley Europe Australia
Far East Index, Morgan Stanley World Index, Russell 2000 Index, or other
variable annuity separate accounts or mutual funds with investment objectives
similar to those of the Funds.

                               FEDERAL TAX STATUS

The following discussion of federal income tax treatment of amounts received
under a variable annuity contract does not cover all situations or issues. It is
not intended as tax advice. Consult a qualified tax adviser to apply the law to
your circumstances. Tax laws can change, even for contracts that have already
been issued. Tax law revisions, with unfavorable consequences, could have
retroactive effect on previously issued contracts or on later voluntary
transactions in previously issued contracts.

We are taxed as a life insurance company under Subchapter L of the Internal
Revenue Code (the "Code"). Since the operations of VAA are a part of, and are
taxed with, our operations, VAA is not separately taxed as a "regulated
investment company" under Subchapter M of the Code.

As to tax-qualified contracts, the law does not now provide for payment of
federal income tax on dividend income or capital gains distributions from Fund
shares held in VAA or upon capital gains realized by VAA on redemption of Fund
shares. When a non-tax-qualified contract is issued in connection with a
deferred compensation plan or arrangement, all rights, discretions and powers
relative to the contract are vested in the employer and you must look only to
your employer for the payment of deferred compensation benefits. Generally, in
that case, an annuitant will have no "investment in the contract" and amounts
received by you from your employer under a deferred compensation arrangement
will be taxable in full as ordinary income in the years you receive the
payments.


The income and gains within an annuity contract are generally tax deferred.
Within a tax-qualified plan, the plan itself provides tax deferral. Therefore,
the tax-deferred treatment otherwise available to an annuity contract is not a
factor to consider when purchasing an annuity within a tax-qualified plan or
arrangement.


The contracts are considered annuity contracts under Section 72 of the Code,
which generally provides for taxation of annuities. Under existing provisions of
the Code, any increase in the contract value is not taxable to you as the owner
or annuitant until you receive it, either in the form of annuity payments, as
contemplated by the contract, or in some other form of distribution. The owner
of a non-tax qualified contract must be a natural person for this purpose. With
certain exceptions, where the owner of a non-tax qualified contract is a
non-natural person (corporation, partnership or trust) any increase in the
accumulation value of the contract attributable to purchase payments made after
February 28, 1986 will be treated as ordinary income received or accrued by the
contract owner during the current tax year.

When annuity payments begin each payment is taxable under Section 72 of the Code
as ordinary income in the year of receipt if you have neither paid any portion
of the purchase payments nor previously been taxed on any portion of the
purchase payments. If any portion of the purchase payments has been paid from or
included in your taxable income, this aggregate amount will be considered your
"investment in the contract." You will be entitled to exclude from your taxable
income a portion of each annuity payment equal to your "investment in the
contract" divided by the period of expected annuity payments, determined by your
life expectancy and the form of annuity benefit. Once you recover your
"investment in the contract," all further annuity payments will be included in
your taxable income.

If you elect to receive the accumulated value in a single sum in lieu of annuity
payments, any amount you receive or withdraw in excess of the "investment in the
contract" will normally be taxed as ordinary income in the year received. A
partial withdrawal of contract values is taxable as income to the extent that
the accumulated value of the contract immediately before the payment exceeds the
"investment in the contract." Such a withdrawal is

Form 8902

                                       21
<PAGE>   56

treated as a distribution of earnings first and only second as a recovery of
your "investment in the contract." Any part of the value of the contract that
you assign or pledge to secure a loan will be taxed as if it had been a partial
withdrawal and may be subject to a penalty tax.

There is a penalty tax equal to 10% of any amount that must be included in gross
income for tax purposes. The penalty will not apply to a redemption that is:

- - received on or after the taxpayer reaches age 59 1/2;

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

- - attributable to the taxpayer's becoming disabled;

- - made as a series of substantially equal periodic payments for the life of the
  annuitant (or joint lives of the annuitant and beneficiary);

- - from a contract that is a qualified funding asset for purposes of a structured
  settlement;

- - made under an annuity contract that is purchased with a single premium and
  with an annuity payout date not later than a year from the purchase of the
  annuity;

- - incident to divorce, or

- - taken from an IRA for a qualified first-time home purchase (up to $10,000) or
  qualified education expenses.

If you elect not to have withholding apply to an early withdrawal or if an
insufficient amount is withheld, you may be responsible for payment of estimated
tax. You may also incur penalties under the estimated tax rules if the
withholding and estimated tax payments are not sufficient. If you fail to
provide your taxpayer identification number, any payments under the contract
will automatically be subject to withholding.

TAX-DEFERRED ANNUITIES

Under the provisions of Section 403(b) of the Code, employees may exclude from
their gross income purchase payments made for annuity contracts purchased for
them by public educational institutions and certain tax-exempt organizations
which are described in Section 501(c)(3) of the Code. You may make this
exclusion to the extent that the aggregate purchase payments plus any other
amounts contributed to purchase the contract and toward benefits under qualified
retirement plans do not exceed your exclusion allowance as determined in
Sections 403(b) and 415 of the Code. Employee contributions are, however,
subject to social security (FICA) tax withholding. All amounts you receive under
a contract, either in the form of annuity payments or cash withdrawal, will be
taxed under Section 72 of the Code as ordinary income for the year received,
except for exclusion of any amounts representing "investment in the contract."
Under certain circumstances, amounts you receive may be used to make a "tax-free
rollover" into one of the types of individual retirement arrangements permitted
under the Code. Amounts you receive that are eligible for "tax-free rollover"
will be subject to an automatic 20% withholding unless you directly roll over
such amounts from the tax-deferred annuity to the individual retirement
arrangement.

With respect to earnings accrued and purchase payments made after December 31,
1988, for a salary reduction agreement under Section 403(b) of the Code,
distributions may be paid only when the employee:

- - attains age 59 1/2,

- - separates from the employer's service,

- - dies,

- - becomes disabled as defined in the Code, or

- - incurs a financial hardship as defined in the Code.

In the case of hardship, cash distributions may not exceed the amount of your
purchase payments. These restrictions do not affect your right to transfer
investments among the Funds and do not limit the availability of transfers
between tax-deferred annuities.

QUALIFIED PENSION OR PROFIT-SHARING PLANS

Under present law, purchase payments made by an employer or trustee, for a plan
or trust qualified under Section 401(a) or 403(a) of the Code, are generally
excludable from the employees gross income. Any purchase payments made by the
employee, or which are considered taxable income to the employee in the year
such payments are made, constitute an "investment in the contract" under Section
72 of the Code for the employee's annuity benefits. Salary reduction payments to
a profit sharing plan qualifying under Section 401(k) of the Code are generally
excludable from the employee's gross income.

The Code requires plans to prohibit any distribution to a plan participant prior
to age 59 1/2, except in the event of death, total disability or separation from
service (special rules apply for plan terminations). Distributions must begin no
later than April 1 of the calendar year following the year in which the
participant reaches age 70 1/2. Premature distribution of benefits or
contributions in excess of those permitted by the Code may result in certain
penalties under the Code.

If an employee, or one or more of the beneficiaries, receives the total amounts
payable with respect to an employee within one taxable year after age 59 1/2 on
account of the employee's death or separation from service of the employer, any
amount received in excess of the employee's "investment in the contract" may be
taxed under special 5-year forward averaging rules. Five-year averaging will no
longer be available after 1999 except for certain grandfathered individuals. You
can elect to have that portion of a lump-sum distribution attributable to years
of participation prior to January 1, 1974 given capital gains treatment. The
percentage of pre-74 distribution subject to capital gains treatment decreases
as follows: 100%, 1987; 95%, 1988; 75%, 1989; 50%, 1990; and 25%, 1991. For tax
years 1992 and later no capital gains treatment is available (except that
taxpayers who were age 50 before 1986 may still elect capital gains treatment).
If you receive such a distribution you may be able to make a "tax-free rollover"
of the distribution less your "investment in the contract" into another
qualified plan in which you are a participant or into one of the types of
individual retirement arrangements permitted under the Code. Your surviving
spouse receiving such a distribution may be able to make a tax-free rollover to
one of the types of individual retirement arrangements permitted under the Code.
Amounts received that are eligible for "tax-free rollover" will be subject to an
automatic 20% withholding unless such amounts are directly rolled over to
another qualified plan or individual retirement arrangement.

INDIVIDUAL RETIREMENT ANNUITIES (IRA)

Section 408(b) of the Code provides that an individual may invest an amount up
to $2,000 per year of earned income in an IRA and claim it as a personal tax
deduction if such person is not an "active participant" in an employer
maintained qualified retirement plan or such person has adjusted gross income
which does not exceed the "applicable dollar limit." For a single taxpayer, the
applicable dollar limitation is $30,000, with the amount of IRA contribution
which may be deducted reduced proportionately for Adjusted Gross Income between
$30,000-$40,000. For married couples filing jointly, the applicable dollar
limitation is $50,000, with the amount of IRA contribution which may be deducted
reduced proportionately for Adjusted Gross Income between $50,000-$60,000. There
is no deduction allowed for IRA contributions when Adjusted Gross Income reaches
$40,000 for individuals and $60,000 for married couples filing jointly. In the
alternative, an individual otherwise qualified for an IRA may elect to
contribute to an IRA for the individual and for the individual's non-working
spouse, with the total deduction limited to $4,000.

You may make non-deductible IRA contributions to the extent they are ineligible
to make deductible IRA contributions. Any amount received from another qualified
plan (including another individual retirement arrangement) which is eligible as
a "tax-free rollover" may be invested in an IRA, and is not counted toward the
overall contribution limit. Earnings on nondeductible IRA contributions are not
subject to tax until they are withdrawn. The combined limit on designated
nondeductible and deductible contributions for a tax year is the lesser of 100%
of compensation or $2,000 ($4,000 in the case of an additional contribution to a
spousal IRA).

Form 8902

                                       23
<PAGE>   58

Generally, distributions (all or part) made prior to age 59 1/2 (except in the
case of death or disability) will result in a penalty tax of 10% plus ordinary
income tax treatment of the amount received. Additionally, there is an excise
tax of 6% of the amount contributed in excess of either the deductible limit or
nondeductible limit, as indicated above, if such amount is not withdrawn prior
to the filing of the income tax return for the year of contribution or applied
as an allowable contribution for a subsequent year. The excise tax will continue
to apply each year until the excess contribution is corrected. Distributions
after age 59 1/2 are treated as ordinary income at the time received.
Distributions must commence before April 1 following the year in which the
individual reaches age 70 1/2. A 50% nondeductible excise tax is imposed on the
excess in any tax year of the amount that should have been distributed over the
amount actually distributed.

Section 408A of the Code provides for a special type of IRA called a Roth IRA.
No tax deduction is allowed for contributions to a Roth IRA, but assets grow on
a tax-deferred basis. Under certain circumstances, withdrawals from a Roth IRA
can be excludable from income. Eligibility for a Roth IRA is based on adjusted
gross income and filing status. Special rules apply which allow traditional IRAs
to be rolled over or converted to a Roth IRA.

SIMPLIFIED EMPLOYEE PENSION PLANS (SEPPS)

Under Section 408 of the Code, employers may establish SEPPs for their
employees. Under these plans the employer may contribute on behalf of an
employee to an individual retirement account or annuity. The amount of the
contribution is excludable from the employee's income.

Certain employees who participate in a SEPP will be entitled to elect to have
the employer make contributions to a SEPP on their behalf or to receive the
contributions in cash. If the employee elects to have contributions made on the
employee's behalf to a SEPP, it is not treated as current taxable income to the
employee. Elective deferrals under a SEPP are subject to an inflation-indexed
limit which is $10,000 for 1998. Salary-reduction SEPPs are available only if at
least 50% of the employees elect to have amounts contributed to the SEPP and if
the employer has 25 or fewer employees at all times during the preceding year.
New salary-reduction SEPPs may not be established after 1996.

An employee may also take a deduction for individual contributions to the IRA,
subject to the limits applicable to IRAs in general. Withdrawals from the IRAs
to which the employer contributes must be permitted. These withdrawals, however,
are subject to the general rules with respect to withdrawals from IRAs.

WITHHOLDING ON DISTRIBUTION

Distributions from tax-deferred annuities or qualified pension or profit sharing
plans that are eligible for "tax-free rollover" will be subject to an automatic
20% withholding unless such amounts are directly rolled over to an individual
retirement arrangement or another qualified plan. Federal income tax withholding
is required on annuity payments. However, recipients of annuity payments are
allowed to elect not to have the tax withheld. This election may be revoked at
any time and withholding would begin after that. If you do not give us your
taxpayer identification number any payments under the contract will
automatically be subject to withholding.

APPENDIX A

                            IRA DISCLOSURE STATEMENT

This statement is designed to help you understand the requirements of federal
tax law which apply to your individual retirement annuity (IRA), your Roth IRA,
your simplified employee pension IRA (SEPP-IRA) for employer contributions, your
Savings Incentive Match Plan for Employees (SIMPLE) IRA, or to one you purchase
for your spouse. You can obtain more information regarding your IRA either from
your sales representative or from any district office of the Internal Revenue
Service.

FREE LOOK PERIOD

The annuity contract offered by this prospectus gives you the opportunity to
return the contract for a full refund within 10 days after it is delivered. This
is a more liberal provision than is required in connection with IRAs. To
exercise this "free-look" provision write or call the address shown below:

Telephone: 1-800-366-6654 -- 8:30 a.m. - 4:30 p.m. (Eastern time zone)

ELIGIBILITY REQUIREMENTS

IRAs are intended for all persons with earned compensation whether or not they
are covered under other retirement programs. Additionally if you have a
non-working spouse (and you file a joint tax return), you may establish an IRA
on behalf of your non-working spouse. A working spouse may establish his or her
own IRA. A divorced spouse receiving taxable alimony (and no other income) may
also establish an IRA.

CONTRIBUTIONS AND DEDUCTIONS

Contributions to your IRA will be deductible if you are not an "active
participant" in an employer maintained qualified retirement plan or you have
Adjusted Gross Income which does not exceed the "applicable dollar limit". IRA
(or SEPP-IRA) contributions must be made by no later than the time you file your
income tax return for that year. For a single taxpayer, the applicable dollar
limitation is $30,000, with the amount of IRA contribution which may be deducted
reduced proportionately for Adjusted Gross Income between $30,000-$40,000. For
married couples filing jointly, the applicable dollar limitation is $50,000,
with the amount of IRA contribution which may be deducted reduced
proportionately for Adjusted Gross Income between $50,000-$60,000. There is no
deduction allowed for IRA contributions when Adjusted Gross Income reaches
$40,000 for individuals and $60,000 for married couples filing jointly.

Contributions made by your employer to your SEPP-IRA are excludable from your
gross income for tax purposes in the calendar year for which the amount is
contributed. Certain employees who participate in a SEPP-IRA will be entitled to
elect to have their employer make contributions to their SEPP-IRA on their
behalf or to receive the contributions in cash. If the employee elects to have
contributions made on the employee's behalf to the SEPP, those funds are not
treated as current taxable income to the employee. Elective deferrals under a
SEPP-IRA are subject to an inflation-adjusted limit which is $10,000 for 1998.
Salary-reduction SEPP-IRAs (also called "SARSEPs") are available only if at
least 50% of the employees elect to have amounts contributed to the SEPP-IRA and
if the employer has 25 or fewer employees at all times during the preceding
year. New salary-reduction SEPPs may not be established after 1996.

The IRA maximum annual contribution and your tax deduction is limited to the
lesser of: (1) $2,000 or (2) 100% of your earned compensation. Contributions in
excess of the deduction limits may be subject to penalty. See below.

Form 8902

                                       25
<PAGE>   60

Under a SEPP-IRA agreement, the maximum annual contribution which your employer
may make on your behalf to a SEPP-IRA contract which is excludable from your
income is the lesser of 15% of your salary or $24,000. An employee who is a
participant in a SEPP-IRA agreement may make after-tax contributions to the
SEPP-IRA contract, subject to the contribution limits applicable to IRAs in
general. Those employee contributions will be deductible subject to the
deductibility rules described above.

The maximum tax deductible annual contribution that a divorced spouse with no
other income may make to an IRA is the lesser of (1) $2,000 or (2) 100% of
taxable alimony.

If you or your employer should contribute more than the maximum contribution
amount to your IRA or SEPP-IRA, the excess amount will be considered an "excess
contribution". You are permitted to withdraw an excess contribution from your
IRA or SEPP-IRA before your tax filing date without adverse tax consequences.
If, however, you fail to withdraw any such excess contribution before your tax
filing date, a 6% excise tax will be imposed on the excess for the tax year of
contribution.

Once the 6% excise tax has been imposed, an additional 6% penalty for the
following tax year can be avoided if the excess is (1) withdrawn before the end
of the following year, or (2) treated as a current contribution for the
following year. (See Premature Distributions for penalties imposed on withdrawal
when the contribution exceeds $2,000).

IRA FOR NON-WORKING SPOUSE

If you establish an IRA for yourself, you may also be eligible to establish an
IRA for your "non-working" spouse. In order to be eligible to establish such a
spousal IRA, you must file a joint tax return with your spouse and if your
non-working spouse has compensation, his/her compensation must be less than your
compensation for the year. Contributions of up to $2,000 each may be made to
your IRA and the spousal IRA if the combined compensation of you and your spouse
is at least equal to the amount contributed. If requirements for deductibility
(including income levels) are met, you will be able to deduct an amount equal to
the least of (i) the amount contributed to the IRA's; (ii) $4,000; or (iii) 100%
of your combined gross income.

Contributions in excess of the contribution limits may be subject to penalty.
See above under "Contributions and Deductions". If you contribute more than the
allowable amount, the excess portion will be considered an excess contribution.
The rules for correcting it are the same as discussed above for regular IRAs.

Other than the items mentioned in this section, all of the requirements
generally applicable to IRAs are also applicable to IRAs established for
non-working spouses.

ROLLOVER CONTRIBUTION

Once every year, you are permitted to withdraw any portion of the value of your
IRA or SEPP-IRA and reinvest it in another IRA or bond. Withdrawals may also be
made from other IRAs and contributed to this contract. This transfer of funds
from one IRA to another is called a "rollover" IRA. To qualify as a rollover
contribution, the entire portion of the withdrawal must be reinvested in another
IRA within 60 days after the date it is received. You will not be allowed a
tax-deduction for the amount of any rollover contribution.

similar type of rollover to an IRA can be made with the proceeds of a qualified
distribution from a qualified retirement plan or tax-sheltered annuity. Properly
made, such a distribution will not be taxable until you receive payments from
the IRA created with it. Unless you were a self-employed participant in the
distributing plan, you may later roll over such a contribution to another
qualified retirement plan as long as you have not mixed it with IRA (or
SEPP-IRA) contributions you have deducted from your income. (You may roll less
than all of a qualified distribution into an IRA, but any part of it not rolled
over will be currently includable in your income without any capital gains
treatment.)

PREMATURE DISTRIBUTIONS

At no time can your interest in your IRA or SEPP-IRA be forfeited. To insure
that your contributions will be used for your retirement, the federal tax law
does not permit you to use your IRA or SEPP-IRA as security for a loan.
Furthermore, as a general rule, you may not sell or assign your interest in your
IRA or SEPP-IRA to anyone. Use of an IRA (or SEPP-IRA) as security or assignment
of it to another will invalidate the entire annuity. It then will be includable
in your income in the year it is invalidated and will be subject to a 10%
penalty tax if you are not at least age 59 1/2 or totally disabled. (You may,
however, assign your IRA or SEPP-IRA without penalty to your former spouse in
accordance with the terms of a divorce decree.)

You may surrender any portion of the value of your IRA (or SEPP-IRA). In the
case of a partial surrender which does not qualify as a rollover, the amount
withdrawn will be includable in your income and subject to the 10% penalty if
you are not at least age or 59 1/2 totally disabled unless you comply with
special rules requiring distributions to be made at least annually over your
life expectancy.

The 10% penalty tax does not apply to the withdrawal of an excess contribution
as long as the excess is withdrawn before the due date of your tax return.
Withdrawals of excess contributions after the due date of your tax return will
generally be subject to the 10% penalty unless the excess contribution results
from erroneous information from a plan trustee making an excess rollover
contribution or unless you are over age 59 1/2 or are disabled.

DISTRIBUTION AT RETIREMENT

Once you have attained age 59 1/2 (or have become totally disabled), you may
elect to receive a distribution of your IRA (or SEPP-IRA) regardless of when you
actually retire. You may elect to receive the distribution in either one sum or
under any one of the periodic payment options available under the contract. The
distributions from your IRA under any one of the periodic payment options or in
one sum will be treated as ordinary income as you receive them.

INADEQUATE DISTRIBUTIONS -- 50% TAX

Your IRA or SEPP-IRA is intended to provide retirement benefits over your
lifetime. Thus, federal law requires that you either (1) receive a lump-sum
distribution of your IRA by April 1 of the year following the year in which you
attain age 70 1/2 or (2) start to receive periodic payments by that date. If you
elect to receive periodic payments, those payments must be sufficient to pay out
the entire value of your IRA during your life expectancy (or over the joint life
expectancies of you and your spouse). If the payments are not sufficient to meet
these requirements, an excise tax of 50% will be imposed on the amount of any
underpayment.

DEATH BENEFITS

If you, (or your surviving spouse) die before receiving the entire value of your
IRA (or SEPP-IRA), the remaining interest must be distributed to your
beneficiary (or your surviving spouse's beneficiary) in one lump-sum within 5
years of death, or applied to purchase an immediate annuity for the beneficiary.
This annuity must be payable over the life expectancy of the beneficiary
beginning within one year after your or your spouse's death. If your spouse is
the designated beneficiary, he or she is treated as the owner of the IRA. If
minimum required distributions have begun, the entire amount must be distributed
at least as rapidly as if the owner had survived. A distribution of the balance
of your IRA upon your death will not be considered a gift for federal tax
purposes, but will be included in your gross estate for purposes of federal
estate taxes.

ROTH IRAS

Section 408A of the Code permits eligible individuals to contribute to a type of
IRA known as a "Roth IRA." Contributions may be made to a Roth IRA by taxpayers
with adjusted gross incomes of less than $160,000 for married individuals filing
jointly and less than $100,000 for single individuals. Married individuals
filing separately are not eligible to contribute to a Roth IRA. The maximum
amount of contributions allowable for any

Form 8902

                                       27
<PAGE>   62

taxable year to all Roth IRAs maintained by an individual is generally the
lesser of $2,000 and 100% of compensation for that year (the $2,000 limit is
phased out for incomes between $150,000 and $160,000 for married and between
$95,000 and $110,000 for singles). The contribution limit is reduced by the
amount of any contributions made to a non-Roth IRA. Contributions to a Roth IRA
are not deductible.

For taxpayers with adjusted gross income of $100,000 or less, all or part of
amounts in a non-Roth IRA may be converted, transferred or rolled over to a Roth
IRA. Some or all of the IRA value will typically be includable in the taxpayer's
gross income. If such a rollover, transfer or conversion occurred before 1/1/99,
the portion of the amount includable in gross income must be included in income
ratably over the next four years beginning with the year in which the
transaction occurred. Provided a rollover contribution meets the requirements
for IRAs under Section 408(d)(3) of the Code, a rollover may be made from a Roth
IRA to another Roth IRA.

UNDER SOME CIRCUMSTANCES, IT MAY NOT BE ADVISABLE TO ROLL OVER, TRANSFER OR
CONVERT ALL OR PART OF A NON-ROTH IRA TO A ROTH IRA. PERSONS CONSIDERING A
ROLLOVER, TRANSFER OR CONVERSION SHOULD CONSULT THEIR OWN TAX ADVISOR.

"Qualified distributions" from a Roth IRA are excludable from gross income. A
"qualified distribution" is a distribution that satisfies two requirements: (1)
the distribution must be made (a) after the owner of the IRA attains age 59 1/2;
(b) after the owner's death; (c) due to the owner's disability; or (d) for a
qualified first time homebuyer distribution within the meaning of Section
72(t)(2)(F) of the Code; and (2) the distribution must be made in the year that
is at least five years after the first year for which a contribution was made to
any Roth IRA established for the owner or five years after a rollover, transfer
or conversion was made from a non-Roth IRA to a Roth IRA. Distributions from a
Roth IRA that are not qualified distributions will be treated as made first from
contributions and then from earnings, and taxed generally in the same manner as
distributions from a non-Roth IRA.

Distributions from a Roth IRA need not commence at age 70 1/2. However, if the
owner dies before the entire interest in a Roth IRA is distributed, any
remaining interest in the contract must be distributed by December 31 of the
calendar year containing the fifth anniversary of the owner's death subject to
certain exceptions.

PROTOTYPE STATUS

The Internal Revenue Service has been requested to review the format of your
SEPP, and to issue an opinion letter to Ohio National Life stating that your IRA
qualifies as a prototype SEPP.

REPORTING TO THE IRS

Whenever you are liable for one of the penalty taxes discussed above (6% for
excess contributions, 10% for premature distributions or 50% for underpayments),
you must file Form 5329 with the Internal Revenue Service. The form is to be
attached to your federal income tax return for the tax year in which the penalty
applies. Normal contributions and distributions must be shown on your income tax
return for the year to which they relate.

CUSTODIAN

We have a custody agreement with Firstar Bank, N.A., Cincinnati, Ohio, under
which Firstar holds custody of VAA's assets. The agreement provides for Firstar
to purchase Fund shares at their net asset value determined as of the end of the
valuation period during which we receive the deposit. At our instruction,
Firstar redeems the Fund shares held by VAA at their net asset value determined
as of the end of the valuation period during which we receive or make a
redemption request. In addition, Firstar keeps appropriate records of all of
VAA's transactions in Fund shares.

The custody agreement requires Firstar to always have aggregate capital, surplus
and undivided profit of not less than $2 million. It does not allow Firstar to
resign until (a) a successor custodian bank having the above qualifications has
agreed to serve as custodian, or (b) VAA has been completely liquidated and the
liquidation proceeds properly distributed. Subject to these conditions, the
custody agreement may be terminated by either us or Firstar upon sixty days
written notice. We pay Firstar a fee for its services as custodian.


INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


The financial statements of VAA as of December 31, 1999 and for the periods
indicated and our consolidated financial statements as of December 31, 1999 and
1998 and for the periods indicated have been included in reliance upon the
reports of KPMG LLP, independent certified public accountants, also appearing
herein, and upon that firm's authority as experts in accounting and auditing.


UNDERWRITER

We offer the contracts continuously. Before May 1, 1997, The O. N. Equity Sales
Company ("ONESCO"), a wholly-owned subsidiary of ours, was the principal
underwriter of the contracts. Since May 1, 1997, the principal underwriter has
been Ohio National Equities, Inc. ("ONEQ"), another wholly-owned subsidiary of
ours. The aggregate amount of commissions paid to ONESCO and ONEQ for contracts
issued by VAA, and the amounts retained by ONESCO and ONEQ, for each of the last
three years have been:

CALCULATION OF MONEY MARKET YIELD


The annualized current yield of the Money Market subaccount for the seven days
ended on December 31, 1999, was 4.22%. This was calculated by determining the
net change, exclusive of capital changes, in the value of a hypothetical
pre-existing account having a balance of one Money Market accumulation unit at
the beginning of the seven-day period, dividing the net change in value by the
beginning value to obtain the seven-day return, and multiplying the difference
by 365/7. The result is rounded to the nearest hundredth of one percent.


TOTAL RETURN

The average annual compounded rate of return for a contract for each subaccount
over a given period is found by equating the initial amount invested to the
ending redeemable value using the following formula:

                                 P(1 + T)n = ERV

      where:     P = a hypothetical initial payment of $1,000,
                 T = the average annual total return,
                 n = the number of years, and
                 ERV = the ending redeemable value of a hypothetical $1,000
                 beginning-of-period payment at the end of the period
                 (or fractional portion thereof).

We will up-date standardized total return data based upon Fund performance in
the subaccounts within 30 days after each calendar quarter.

In addition, we may present non-standardized total return data, using the above
formula but based upon Fund performance before the date we first offered this
series of contracts (May 1, 1998). This will be presented as if the same charges
and deductions applying to these contracts had been in effect from the inception
of each Fund.

The average annual total returns for the contracts from the inception of each

LOANS UNDER TAX-SHELTERED ANNUITIES

Contracts issued as tax-sheltered annuities under plans qualifying under Section
403(b) of the Code, and allowing for voluntary contributions only, are eligible
for loans secured by a security interest in the contract. A loan must be for at
least $1,000 and may only be made from the Guaranteed Account. The loan amount
is limited by the maximum loan formula described in your contract.

We charge an annual effective rate of interest up to 7%. You must generally
repay your loans within 5 years (or 20 years if you use the loan to purchase
your primary home).

The amount of the death benefit, the amount payable on a full surrender and the
amount that will be applied to provide an annuity will all be reduced by your
loan balance, including accrued interest.

                          INDEPENDENT AUDITORS' REPORT



     The Board of Directors
     The Ohio National Life Insurance Company:


     We have audited the accompanying consolidated balance sheets of The Ohio
     National Life Insurance Company (a wholly owned subsidiary of Ohio National
     Financial Services, Inc.) and subsidiaries (the Company) as of December 31,
     1999 and 1998, and the related consolidated statements of income, equity
     and cash flows for each of the years in the three-year period ended
     December 31, 1999. These consolidated financial statements are the
     responsibility of the Company's management. Our responsibility is to
     express an opinion on these consolidated financial statements based on our
     audits.

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

     In our opinion, the consolidated financial statements referred to above
     present fairly, in all material respects, the financial position of The
     Ohio National Life Insurance Company and subsidiaries as of December 31,
     1999 and 1998, and the results of their operations and their cash flows for
     each of the years in the three-year period ended December 31, 1999, in
     conformity with generally accepted accounting principles.

            THE OHIO NATIONAL LIFE INSURANCE COMPANY AND SUBSIDIARIES
     (a wholly owned subsidiary of Ohio National Financial Services, Inc.)

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998 and 1997

  (1)   ORGANIZATION, CONSOLIDATION POLICY AND BUSINESS DESCRIPTION

        The Ohio National Life Insurance Company (ONLIC) is a stock life
        insurance company. Ohio National Life Assurance Corporation (ONLAC) is a
        wholly owned stock life insurance subsidiary included in the
        consolidated financial statements. ONLIC and its subsidiaries are
        collectively referred to as the "Company". All significant intercompany
        accounts and transactions have been eliminated in consolidation.

        On February 12, 1998, ONLIC's Board of Directors approved a plan of
        reorganization for the Company under the provision of Sections 3913.25
        to 3913.38 of the Ohio Revised Code relating to mutual insurance holding
        companies. The plan of reorganization was approved by the Company's
        policyholders and by the Ohio Department of Insurance and became
        effective on August 1, 1998 (Effective Date). As part of the
        reorganization (see footnote (1)(k)), ONLIC became a stock company 100%
        owned by Ohio National Financial Services, Inc. (ONFS). ONFS is 100%
        owned by Ohio National Mutual Holdings, Inc. (ONMH), an Ohio mutual
        holding company.

        ONLIC and ONLAC are life and health insurers licensed in 47 states, the
        District of Columbia and Puerto Rico. The Company offers a full range of
        life, health and annuity products through exclusive agents and other
        distribution channels and is subject to competition from other insurers
        throughout the United States. The Company is subject to regulation by
        the Insurance Departments of states in which it is licensed and
        undergoes periodic examinations by those departments.

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

              LEGAL/REGULATORY RISK is the risk that changes in the legal or
              regulatory environment in which an insurer operates will create
              additional expenses not anticipated by the insurer in pricing its
              products. That is, regulatory initiatives designed to reduce
              insurer profits, new legal theories or insurance company
              insolvencies through guaranty fund assessments may create costs
              for the insurer beyond those recorded in the consolidated
              financial statements. The Company mitigates this risk by offering
              a wide range of products and by operating throughout the United
              States, thus reducing its exposure to any single product or
              jurisdiction, and also by employing underwriting practices which
              identify and minimize the adverse impact of this risk.

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

            THE OHIO NATIONAL LIFE INSURANCE COMPANY AND SUBSIDIARIES
     (a wholly owned subsidiary of Ohio National Financial Services, Inc.)

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998 and 1997

                                 (in thousands)



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

  (2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        The significant accounting policies followed by the Company that
        materially affect financial reporting are summarized below. The
        accompanying consolidated financial statements have been prepared in
        accordance with generally accepted accounting principles (GAAP) which
        differ from statutory accounting practices prescribed or permitted by
        regulatory authorities (see Note 3).

        (a)   VALUATION OF INVESTMENTS AND RELATED GAINS AND LOSSES

              Fixed maturity securities are classified as held-to-maturity when
              the Company has the positive intent and ability to hold the
              securities to maturity and are stated at amortized cost. Fixed
              maturity securities not classified as held-to-maturity and all
              equity securities are classified as available-for-sale and are
              stated at fair value, with the unrealized gains and losses, net of
              adjustments to deferred policy acquisition costs and deferred
              Federal income tax, reported as a separate component of equity
              that would have been required as a charge or credit to operations
              had such unrealized amounts been realized. The Company has no
              securities classified as trading.

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

              Real estate is carried at cost less accumulated depreciation and
              valuation allowances. Other long-term investments are carried on
              the equity basis, adjusted for valuation allowances.

              Realized gains and losses on the sale of investments are
              determined on the basis of specific security identification, net
              of associated deferred acquisition costs and capital gains
              expenses. Any capital gains occurring in the Closed Block
              portfolio are offset by increases in the deferred policyholder
              obligation for that group of policies. Estimates for valuation
              allowances and other than temporary declines are included in
              realized gains and losses on investments.

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

                   Notes to Consolidated Financial Statements

        (c)   REVENUES AND BENEFITS

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

              Universal life products include universal life, variable universal
              life and other interest-sensitive life insurance policies.
              Investment products consist primarily of individual and group
              deferred annuities, annuities without life contingencies and
              guaranteed investment contracts. Revenues for universal life and
              investment products consist of net investment income and cost of
              insurance, policy administration and surrender charges that have
              been earned and assessed against policy account balances during
              the period. Policy benefits and claims that are charged to expense
              include benefits and claims incurred in the period in excess of
              related policy account balances, maintenance costs and interest
              credited to policy account balances.

              Accident and health insurance premiums are recognized as revenue
              in accordance with the terms of the policies. Policy claims are
              charged to expense in the period that the claims are incurred.

        (c)   DEFERRED POLICY ACQUISITION COSTS

              The costs of acquiring new business, principally commissions,
              certain expenses of the policy issue and underwriting department
              and certain variable agency expenses have been deferred. For
              traditional non-participating life insurance products, these
              deferred acquisition costs are predominantly being amortized with
              interest over the premium paying period of the related policies in
              proportion to premium revenue. Such anticipated premium revenue
              was estimated using the same assumptions as were used for
              computing liabilities for future policy benefits. For
              participating life insurance products, deferred policy acquisition
              costs are being amortized in proportion to gross margins of the
              related policies. Gross margins are determined for each issue year
              and are equal to premiums plus investment income less death
              claims, surrender benefits, administrative costs, expected
              policyholder dividends, and the increase in reserve for future
              policy benefits. For universal life and investment products,
              deferred policy acquisition costs are being amortized with
              interest over the lives of the policies in relation to the present
              value of the estimated future gross profits from projected
              interest margins, cost of insurance, policy administration and
              surrender charges. Deferred policy acquisition costs for
              participating life and universal life business are adjusted to
              reflect the impact of unrealized gains and losses on fixed
              maturity securities available-for-sale (see note 2(a)).

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

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998 and 1997

                                 (in thousands)


        (d)   SEPARATE ACCOUNTS

              Separate Account assets and liabilities represent contractholders'
              funds which have been segregated into accounts with specific
              investment objectives. The investment income and gains or losses
              of these accounts accrue directly to the contractholders. The
              activity of the Separate Accounts is not reflected in the
              consolidated statements of income and cash flows except for the
              fees the Company receives for administrative services and risks
              assumed. Amounts provided by the Company to establish Separate
              Account investment portfolios, seed money, are not included in
              Separate Account liabilities.

        (e)   FUTURE POLICY BENEFITS

              Future policy benefits for traditional life have been calculated
              using a net level premium method based on estimates of mortality,
              morbidity, investment yields and withdrawals which were used or
              which were being experienced at the time the policies were issued,
              rather than the assumptions prescribed by state regulatory
              authorities (see note 6).

              Future policy benefits for annuity policies in the accumulation
              phase, universal life and variable universal life policies have
              been calculated based on participants' aggregate account values.

        (f)   PARTICIPATING BUSINESS

              Participating business represents approximately 39% of the
              Company's ordinary life insurance in force in 1999. In 1998 and
              1997, participating business represented approximately 41% and
              42%, respectively, of the Company's ordinary life insurance in
              force. The provision for policyholder dividends is based on
              current dividend scales. Future dividends are provided for in
              future policy benefits based on dividend scales in effect as of
              December 31, 1999.

        (g)   REINSURANCE CEDED

              Reinsurance premiums ceded and reinsurance recoveries on benefits
              and claims incurred are deducted from the respective income and
              expense accounts. Assets and liabilities related to reinsurance
              ceded are reported on a gross basis.

        (h)   FEDERAL INCOME TAX

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

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

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998 and 1997

                                 (in thousands)


        (i)   CASH EQUIVALENTS

              For purposes of the consolidated statements of cash flows, the
              Company considers all short-term investments with original
              maturities of three months or less to be cash equivalents.

        (j)   USE OF ESTIMATES

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

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

        (k)   CLOSED BLOCK

              The Reorganization contained an arrangement, known as a closed
              block (the Closed Block), to provide for dividends on policies
              that were in force on the Effective Date and were within classes
              of individual policies for which the Company had a dividend scale
              in effect at the time of the Reorganization. The Closed Block was
              designed to give reasonable assurance to owners of affected
              policies that assets will be available to support such policies,
              including maintaining dividend scales in effect at the time of the
              Reorganization, if the experience underlying such scales
              continues. The assets, including revenue therefrom, allocated to
              the Closed Block will accrue solely to the benefit of the owners
              of policies included in the Closed Block until the Closed Block is
              no longer in effect. The Company will not be required to support
              the payment of dividends on Closed Block policies from its general
              funds.

              The financial information of the Closed Block, while prepared on a
              GAAP basis, reflects its contractual provisions and not its actual
              results of operations and financial position. Many expenses
              related to the Closed Block operations are charges to operations
              outside of the Closed Block; accordingly, the contribution from
              the Closed Block does not represent the actual profitability of
              the Closed Block operations. Operating costs and expenses outside
              of the Closed Block are, therefore, disproportionate to the
              business outside of the Closed Block.

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

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998 and 1997

        (l)   COMPREHENSIVE INCOME

              Comprehensive income is the total of net income and all non-owner
              changes in equity.

        (m)   EMERGING ACCOUNTING ISSUES

              In June 1998, the Financial Accounting Standards Board issued
              Statement of Financial Accounting Standards No. 133, "Accounting
              for Derivative Instruments and Hedging Activities" (SFAS 133).
              SFAS 133 establishes accounting and reporting standards for
              derivative instruments and for hedging activities. Contracts that
              contain embedded derivatives, such as certain insurance contracts,
              are also addressed by the Statement. SFAS 133 requires that an
              entity recognize all derivatives as either assets or liabilities
              in the statement of financial position and that those assets or
              liabilities be measured at fair value. SFAS 133 is effective for
              all fiscal quarters of fiscal years beginning after January 1,
              2001, with earlier application permitted. The Company is currently
              reviewing the requirements of this Statement and evaluating what,
              if any, impact it will have on consolidated results of operations
              and financial condition.

        (n)   RECLASSIFICATIONS

              Certain amounts in the 1998 and 1997 consolidated financial
              statements have been reclassified to conform with 1999
              presentation.

  (3)   BASIS OF PRESENTATION

        The accompanying consolidated financial statements have been prepared in
        accordance with GAAP which differs from statutory accounting practices
        prescribed or permitted by regulatory authorities. Annual Statements for
        ONLIC and ONLAC, insurance subsidiaries, filed with the Department of
        Insurance of the State of Ohio, are prepared on a basis of accounting
        practices prescribed or permitted by such regulatory authority.
        Prescribed statutory accounting practices include a variety of
        publications of the National Association of Insurance Commissioners
        (NAIC), as well as state laws, regulations and general administrative
        rules. Permitted statutory accounting practices encompass all accounting
        practices not so prescribed. ONLIC and ONLAC have no material permitted
        statutory accounting practices.

        The statutory basis net income and capital and surplus of ONLIC and
        ONLAC after intercompany eliminations included in the accompanying
        consolidated financial statements was $91,163, $51,900 and $53,696 for
        the years ended December 31, 1999, 1998 and 1997, respectively and
        $430,869 and $408,928 as of December 31, 1999 and 1998, respectively.

(6)     FUTURE POLICY BENEFITS AND CLAIMS

        The liability for future policy benefits for universal life insurance
        policies and investment contracts (approximately 79% of the total
        liability for future policy benefits as of December 31, 1999 and 1998)
        has been established based on accumulated contract values without
        reduction for surrender penalty provisions. The average interest rate
        credited on investment product policies was 6.4%, 6.8% and 6.8% for the
        years ended December 31, 1999, 1998 and 1997, respectively.

        The liability for future policy benefits for traditional life policies
        has been established based upon the net level premium method using the
        following assumptions:

        Interest rates: Interest rates vary as follows:

        YEAR OF ISSUE                           INTEREST RATE
        -------------                           -------------
        1999, 1998 and 1997                      4 - 5.5%
        1996 and prior                           2.25 - 6.0%

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

        Mortality: Mortality and morbidity rates are based on published tables,
        guaranteed in insurance contracts.

  (7)   NOTES PAYABLE

        On July 11, 1994, the Company issued $50,000, 8.875% surplus notes, due
        July 15, 2004. On May 21, 1996, the Company issued $50,000, 8.5% surplus
        notes, due May 15, 2026. Concurrent with the issue of the new notes,
        $15,000 of the notes issued on July 11, 1994 were retired. Total
        interest paid was $7,356 for each year during the years ended December
        31, 1999, 1998 and 1997, respectively.

        The notes have been issued in accordance with Section 3941.13 of the
        Ohio Revised Code. Interest payments, scheduled semi-annually, must be
        approved for payment by the Director of the Department of Insurance of
        the State of Ohio. All issuance costs have been capitalized and are
        being amortized over the terms of the notes.

  (8)   FEDERAL INCOME TAX

        Prior to 1984, the Life Insurance Company Income Tax Act of 1959, as
        amended by the Deficit Reduction Act of 1984 (DRA), permitted the
        deferral from taxation of a portion of statutory income under certain
        circumstances. In these situations, the deferred income was accumulated
        in the Policyholders' Surplus Account (PSA). Management considers the
        likelihood of distributions from the PSA to be remote; therefore, no
        Federal income tax has been provided for such distributions in the
        financial statements. The DRA eliminated any additional deferrals to the
        PSA. Any distributions from the PSA, however, will continue to be
        taxable at the then current tax rate. The pre-tax balance of the PSA is
        approximately $5,257 as of December 31, 1999.

        Total income taxes for the years ended December 31, 1999, 1998 and 1997
        were allocated as follows:

                                                 1999         1998        1997

        The Company has determined that a deferred tax asset valuation allowance
        was not needed as of December 31, 1999 and 1998. In assessing the
        realization of deferred tax assets, management considers whether it is
        more likely than not that the deferred tax assets will be realized. The
        ultimate realization of deferred tax assets is dependent upon the
        generation of future taxable income during the periods in which those
        temporary differences become deductible. Management considers primarily
        the scheduled reversal of deferred tax liabilities and tax planning
        strategies in making this assessment and believes it is more likely than
        not the Company will realize the benefits of the deductible differences
        remaining as of December 31, 1999.

  (9)   DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

        Statement of Financial Accounting Standards No. 107, Disclosures about
        Fair Value of Financial Instruments (SFAS 107) requires disclosure of
        fair value information about existing on and off-balance sheet financial
        instruments. SFAS 107 excludes certain assets and liabilities, including
        insurance contracts, other than policies such as annuities that are
        classified as investment contracts, from its disclosure requirements.
        Accordingly, the aggregate fair value amounts presented do not represent
        the underlying value of the Company. The tax ramifications of the
        related unrealized gains and losses can have a significant effect on
        fair value estimates and have not been considered in the estimates.

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

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

               INVESTMENT SECURITIES - Fair value for equity securities and
               fixed maturity securities are the same as market value. Market
               value generally represents quoted market prices traded in the
               public market place. For fixed maturity securities not actively
               traded, or in the case of private placements, fair value is
               estimated by discounting expected future cash flows using a
               current market rate applicable to the yield, credit quality and
               duration of investments.

               SEPARATE ACCOUNT ASSETS AND LIABILITIES - The fair value of
               assets held in Separate Accounts is based on quoted market
               prices. The fair value of liabilities related to Separate
               Accounts is the accumulated contract values in the Separate
               Account portfolios.

               MORTGAGE LOANS ON REAL ESTATE - The fair value for mortgage loans
               on real estate is estimated using discounted cash flow analyses,
               using interest rates currently being offered for similar loans to
               borrowers with similar credit ratings. Loans with similar
               characteristics are aggregated for purposes of the calculations.

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

               NOTE PAYABLE - The fair value for the note payable was determined
               by discounting the scheduled cash flows of the note using a
               market rate applicable to the yield, credit quality and maturity
               of a similar debt instrument.

               POLICYHOLDERS' DIVIDEND ACCUMULATION AND OTHER POLICYHOLDER FUNDS
               - The carrying amount reported in the consolidated balance sheets
               for these instruments approximates their fair value.

 (10)   ADDITIONAL FINANCIAL INSTRUMENTS DISCLOSURE

        (a)   FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

              The Company is a party to financial instruments with
              off-balance-sheet risk in a normal course of business through
              management of its investment portfolio. The Company had
              outstanding commitments to fund mortgage loans, bonds and venture
              capital partnerships of approximately $74,000 and $229,000 as of
              December 31, 1999 and 1998, respectively. These commitments
              involve varying degrees, elements of credit and market risk in
              excess of amounts recognized in the financial statements. The
              credit risk of all financial instruments, whether on- or
              off-balance sheet, is controlled through credit approvals, limits,
              and monitoring procedures.

 (11)   PENSIONS AND OTHER POSTRETIREMENT BENEFITS

        The Company sponsors a funded pension plan covering all home office
        employees. Retirement benefits are based on years of service and the
        highest average earnings in five of the last ten years. The Company also
        sponsors unfunded pension plans covering home office employees where
        benefits exceed Code 401(a)(17) and Code 415 limits and covering general
        agents. The general agents plan provides benefits based on years of
        service and average compensation during the final five and ten years of
        service

        The Company currently offers eligible retirees the opportunity to
        participate in a health plan. The Company has two health plans, one is
        offered to home office employees, the other is offered to career agents.

           HOME OFFICE EMPLOYEE HEALTH PLAN

           The Company provides a declining service schedule. Only home office
           employees hired prior to January 1, 1996, may become eligible for
           these benefits provided that the employee meets the age and years of
           service requirements. The plan states that an employee becomes
           eligible as follows: age 55 with 20 years of credited service at
           retirement, age 56 with 18 years of service, age 57 with 16 years of
           service grading to age 64 with 2 years of service. The health plan is
           contributory with retirees contributing approximately 15% of premium
           for coverage.

           health plan is contributory, with retirees contributing approximately
           47% of medical costs.

       For measurement purposes, a nine percent annual rate of increase in the
       per capita cost of covered health care benefits was assumed for 2000. The
       rate was assumed to decrease gradually to five percent for 2001 and
       remain at that level thereafter.

            THE OHIO NATIONAL LIFE INSURANCE COMPANY AND SUBSIDIARIES
      (a wholly owned subsidiary of Ohio National Financial Services, Inc.)

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998, and 1997

                                 (in thousands)




       The health care cost trend rate assumption has a significant effect on
       the amounts reported for the health care plan. A one percentage point
       increase in the assumed health care cost trend rate would increase the
       accumulated postretirement benefit obligation as of December 31, 1999 and
       1998 by $274 and $236, respectively, and the net periodic postretirement
       benefit cost for the years ended December 31, 1999 and 1998 by $17.

       The Company also maintains a qualified contributory defined contribution
       profit sharing plan covering substantially all employees. Company
       contributions to the Profit Sharing Plan are based on the net earnings of
       the Company and are payable at the sole discretion of management. The
       expense reported for contributions to the plan for 1999, 1998, and 1997
       were $1,917, $1,829 and $1,825, respectively.

       The Company has other deferred compensation and supplemental pension
       plans. The expenses for these plans in 1999, 1998 and 1997 were $8,962,
       $6,277 and $5,245, respectively.

 (12)  REGULATORY RISK-BASED CAPITAL, RETAINED EARNINGS AND DIVIDEND
       RESTRICTIONS

       ONLIC and ONLAC exceed the minimum risk-based capital requirements as
       established by the NAIC as of December 31, 1999.

       The Company has designated a portion of retained earnings for separate
       account contingencies and investment guarantees totaling $1,648 as of
       December 31, 1999 and 1998.

       The payment of dividends by the Company to its parent, ONFS, is limited
       by Ohio law. As of December 31, 1999, $25,791 of retained earnings, as
       presented in the accompanying financial statements, is restricted as to
       dividend payments in 2000.

 (13)  BANK LINES OF CREDIT

       As of December 31, 1999 and 1998, ONLIC had a $10,000 unsecured line of
       credit which was not utilized during 1999 and 1998.

 (14)  CONTINGENCIES

       The Company and its subsidiaries are defendants in various legal actions
       arising in the normal course of business. While the outcome of such
       matters cannot be predicted with certainty, management believes such
       matters will be resolved without material adverse impact on the
       financial condition of the Company.

 (15)   REINSURANCE

        The Company routinely enters into reinsurance transactions with other
        insurance companies. This reinsurance involves either ceding certain
        risks to or assuming risks from other insurance companies. The primary
        purpose of ceded reinsurance is to protect the Company from potential
        losses in excess of levels that it is prepared to accept. Reinsurance
        does not discharge the Company from its primary liability to
        policyholders and to the extent that a reinsurer should be unable to
        meet its obligations, the Company would be liable to policyholders. The
        Company has reinsurance recoverables of $95,291 and $78,265 at December
        31, 1999 and 1998, respectively. Ceded premiums approximated 12% and 9%
        of gross earned life and accident and health premiums during 1999 and
        1998, respectively.

 (16)   SEGMENT INFORMATION

        The Company conducts its business in three operating segments:
        individual life insurance, pension and annuities, and other insurance.
        Individual life insurance includes whole life, universal life, variable
        universal life and term life. All products within this segment share
        similar distribution systems and some degree of mortality (loss of life)
        risk. Pension and annuities include fixed and variable deferred and
        immediate annuities issued to individuals as well as guaranteed
        investment and accumulated deposit contracts issued to groups. The
        products in this segment are primarily designed for asset accumulation
        and generation of investment returns. Other insurance includes
        individual disability insurance along with group life and disability
        insurance. These lines are viewed as "complementary" lines that allow us
        to provide a broad portfolio of products to enhance sales in our two
        primary operating segments. In addition to our operating segments,
        certain assets not specifically allocated to support any product line,
        along with various corporate expenses and liabilities, are assigned to
        the corporate segment. All revenue, expense, asset and liability amounts
        are allocated to one of the four segments. As such, the sum of the
        financial information from these segments equals the information for the
        Company as a whole.

OHIO NATIONAL VARIABLE ACCOUNT A
NOTES TO FINANCIAL STATEMENTS

(1) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   Ohio National Variable Account A (the Account) is a separate account of The
   Ohio National Life Insurance Company (ONLIC) and all obligations arising
   under variable annuity contracts are general corporate obligations of ONLIC.
   The account has been registered as a unit investment trust under the
   Investment Company Act of 1940.

   Assets of the Account are invested in portfolio shares of Ohio National Fund,
   Inc., Fidelity Variable Insurance Products Fund, J. P. Morgan Series Trust
   II, Janus Aspen Series, Salomon Brothers Variable Series Fund, Inc., Strong
   Variable Insurance Funds, Inc., Morgan Stanley Universal Funds, Inc., Goldman
   Sachs Variable Insurance Trust, Lazard Retirement Funds and Series Trust
   PaineWebber Mutual Funds (collectively the Funds). The Funds are diversified
   open-end management investment companies. The Funds' investments are subject
   to varying degrees of market, interest and financial risks; the issuers'
   abilities to meet certain obligations may be affected by economic
   developments in their respective industries.

   Annuity reserves are computed for currently payable contracts according to
   the Progressive Annuity Mortality Table. The assumed interest rate is 3.5 or
   4.0 percent depending on the contract selected by the annuitant. Charges to
   annuity reserves for adverse mortality and express risk experience are
   reimbursed to the Account by ONLIC. Such amounts are included in risk and
   administrative expenses.

   Investments are valued at the net asset value of fund shares held at December
   31, 1999. Share transactions are recorded on the trade date. Income and
   capital gain distributions are recorded on the ex-dividend date. Net realized
   capital gains and losses are determined on the basis of average cost.

   ONLIC performs investment advisory services on behalf of the Ohio National
   Fund, Inc. in which the Account invests. For these services, the Company
   receives fees from the mutual funds. These fees are paid to an affiliate of
   the Company.

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

(4) RISK AND ADMINISTRATIVE EXPENSE

   ONLIC charges the Account's assets at the end of each day, equal to 0.25% on
   an annual basis, of the contract value for administrative expenses, based on
   premiums established at the time the contracts are issued.

   Although variable annuity payments differ according to the investment
   performance of the Accounts, they are not affected by mortality or expense
   experience because ONLIC assumes the expense risk and the mortality risk
   under the contracts. ONLIC charges the Accounts' assets for assuming those
   risks, based on the contract value at a rate presently ranging from 0.65% to
   1.25% for mortality and expense risk on an annual basis.

   The expense risk assumed by ONLIC is the risk that the deductions for sales
   and administrative expenses provided for in the variable annuity contracts
   may prove insufficient to cover the cost of those items.

                                                                     (continued)

<PAGE>   110
OHIO NATIONAL VARIABLE ACCOUNT A
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

   The mortality risk results from a provision in the contract in which ONLIC
   agrees to make annuity payments regardless of how long a particular annuitant
   or other payee lives and how long all annuitants or other payees as a class
   live if payment options involving life contingencies are chosen. Those
   annuity payments are determined in accordance with annuity purchase rate
   provisions established at the time the contracts are issued.

(5) CONTRACT CHARGES

   No deduction for a sales charge is made from purchase payments. A contingent
   deferred sales charge ranging from 0% to 7% may be assessed by ONLIC when a
   contract is surrendered or a partial withdrawal of accumulation value is made
   before the annuity payout date.

   A transfer fee is charged for each transfer from one subaccount to another.
   The fee is charged against the contract owner's equity in the subaccount from
   which the transfer is effected.

   State premium taxes presently range from 0% to 2 1/2% for these contracts. In
   those jurisdictions permitting, such taxes will be deducted when annuity
   payments begin. Elsewhere, they will be deducted from purchase payments.

   Each year on the contract anniversary (or at the time of surrender of the
   contract), ONLIC will deduct a contract administration charge of $30 from the
   accumulation value to reimburse it for the expense relating to the
   maintenance of the contract. Total contract administration charges for the
   Account amounted to approximately $390,000 during 1999.

(6) FEDERAL INCOME TAXES

   Operations of the Account form a part of, and are taxed with, operations of
   ONLIC which is taxed as a life insurance company under the Internal Revenue
   Code. Taxes are the responsibility of the contract owner upon termination or
   withdrawal. No Federal income taxes are payable under the present law on
   dividend income or capital gains distribution from the Fund shares held in
   the Account or on capital gains realized by the Account on redemption of the
   Fund shares.

These financial statements are the responsibility of the Account's management.
Our responsibility is to express an opinion on these financial based on our

We conducted our audits in accordance with generally accepted auditing

reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 1999, by correspondence with
the transfer agents of the underlying mutual funds. An audit also includes
assessing the accounting principles used and significant estimates made by

We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Ohio National Variable Account
A as of December 31, 1999, and the results of its operations and its changes in
contract owners' equity for each of the periods indicated herein in conformity
with generally accepted accounting principles.

ITEM 26.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE DEPOSITOR OR
          REGISTRANT

The Organization Chart showing the relationships among the Depositor, the
Registrant and their affiliated entities is on page 4A hereof.

ITEM 27.  NUMBER OF CONTRACTOWNERS


As of March 20, 2000, the Registrant's contracts were owned by 28,199 owners.


ITEM 28.  INDEMNIFICATION

The sixth article of the Depositor's Articles of Incorporation, as amended,
provides as follows:

      Each former, present and future Director, Officer or Employee of the
      Corporation (and his heirs, executors or administrators), or any such
      person (and his heirs, executors or administrators) who serves at the
      Corporation's request as a director, officer, partner, member or employee
      of another corporation, partnership or business organization or
      association of any type whatsoever shall be indemnified by the Corporation
      against reasonable expenses, including attorneys' fees, judgments, fine
      and amounts paid in settlement actually and reasonably incurred by him in
      connection with the defense of any contemplated, pending or threatened
      action, suit or proceeding, civil, criminal, administrative or
      investigative, other than an action by or in the right of the corporation,
      to which he is or may be made a party by reason of being or having been
      such Director, Officer, or Employee of the Corporation or having served at
      the Corporation's request as such director, officer, partner, member or
      employee of any other business organization or association, or in
      connection with any appeal therein, provided a determination is made by
      majority vote of a disinterested quorum of the Board of Directors (a) that
      such a person acted in good faith and in a manner he reasonably believed
      to be in or not opposed to the best interests of the Corporation, and (b)
      that, in any matter the subject of criminal action, suit or proceeding,
      such person had no reasonable cause to believe his conduct was unlawful.
      The termination of any action, suit or proceeding by judgment, order,
      settlement, conviction, or upon a plea of nolo contendere or its
      equivalent, shall not, of itself create a presumption that the person did
      not act in good faith in any manner which he reasonably believed to be in
      or not opposed to the best interests of the Corporation, and with respect
      to any criminal action or proceeding, he had reasonable cause to believe
      that his conduct was unlawful. Such right of indemnification shall not be
      deemed exclusive of any other rights to which such person may be entitled.
      The manner by which the right to indemnification shall be determined in
      the absence of a disinterested quorum of the Board of Directors shall be
      set forth in the Code of Regulations or in such other manner as permitted
      by law. Each former, present, and future Director, Officer or Employee of
      the Corporation (and his heirs, executors or administrators) who serves at
      the Corporation's request as a director, officer, partner, member or
      employee of another corporation, partnership or business organization or
      association of any type whatsoever shall be indemnified by the Corporation
      against reasonable expenses, including attorneys' fees, actually and
      reasonably incurred by him in connection with the defense or settlement of
      any contemplated, pending or threatened action, suit or proceeding, by or
      in the right of the Corporation to procure a judgment in its favor, to
      which he is or may be a party by reason of being or having been such
      Director, Officer or Employee of the Corporation or having served at the
      Corporation's request as such director, officer, partner, member or
      employee of any other business organization or association, or in
      connection with any appeal therein, provided a determination is made by
      majority vote of a disinterested quorum of the Board of Directors (a) that
      such person was not, and has not been adjudicated to have been negligent
      or guilty of misconduct in the performance of his duty to the Corporation
      or to such other business organization or association, and (b) that such
      person acted in good faith and in a manner he reasonably believed to be in
      or not opposed to the best interests of the Corporation.

                                       -5-


<PAGE>   119


      Such right of indemnification shall not be deemed exclusive of any other
      rights to which such person may be entitled. The manner by which the right
      of indemnification shall be determined in the absence of a disinterested
      quorum of the Board of Directors shall be as set forth in the Code of
      Regulations or in such other manner as permitted by law.

In addition, Article XII of the Depositor's Code of Regulations states as
follows:

      If any director, officer or employee of the Corporation may be entitled to
      indemnification by reason of Article Sixth of the Amended Articles of
      Corporation, indemnification shall be made upon either (a) a determination
      in writing of the majority of disinterested directors present, at a
      meeting of the Board at which all disinterested directors present
      constitute a quorum, that the director, officer or employee in question
      was acting in good faith and in a manner he reasonably believed to be in
      or not opposed to the best interests of this Corporation or of such other
      business organization or association in which he served at the
      Corporation's request, and that, in any matter which is the subject of a
      criminal action, suit or proceeding, he had no reasonable cause to believe
      that his conduct was unlawful and in an action by or in the right of the
      Corporation to procure a judgment in its favor that such person was not
      and has not been adjudicated to have been negligent or guilty of
      misconduct in the performance of his duty to the Corporation or to such
      other business organization or association; or (b) if the number of all
      disinterested directors would not be sufficient at any time to constitute
      a quorum, or if the number of disinterested directors present at two
      consecutive meetings of the Board has not been sufficient to constitute a
      quorum, a determination to the same effect as set forth in the foregoing
      clause (a) shall be made in a written opinion by independent legal counsel
      other than an attorney, or a firm having association with it an attorney,
      who has been retained by or who has performed services for this
      Corporation, or any person to be indemnified within the past five years,
      or by the majority vote of the policyholders, or by the Court of Common
      Pleas or the court in which such action, suit or proceeding was brought.
      Prior to making any such determination, the Board of Directors shall first
      have received the written opinion of General Counsel that a number of
      directors sufficient to constitute a quorum, as named therein, are
      disinterested directors. Any director who is a party to or threatened with
      the action, suit or proceeding in question, or any related action, suit or
      proceeding, or has had or has an interest therein adverse to that of the
      Corporation, or who for any other reason has been or would be affected
      thereby, shall not be deemed a disinterested director and shall not be
      qualified to vote on the question of indemnification. Anything in this
      Article to the contrary notwithstanding, if a judicial or administrative
      body determines as part of the settlement of any action, suit or
      proceeding that the Corporation should indemnify a director, officer or
      employee for the amount of the settlement, the Corporation shall so
      indemnify such person in accordance with such determination. Expenses
      incurred with respect to any action, suit or proceeding which may qualify
      for indemnification may be advanced by the Corporation prior to final
      disposition thereof upon receipt of an undertaking by or on behalf of the
      director, officer or employee to repay such amount if it is ultimately
      determined hereunder that he is not entitled to indemnification or to the
      extent that the amount so advanced exceeds the indemnification to which he
      is ultimately determined to be entitled.
