                        FLEXIBLE PREMIUM VARIABLE ANNUITY
               issued by NATIONAL INTEGRITY LIFE INSURANCE COMPANY

    

   

This prospectus describes a flexible premium variable annuity offered by
National Integrity Life Insurance Company, a subsidiary of ARM Financial Group,
Inc. The contracts offered by this prospectus provide several types of benefits,
some of which have tax-favored status under the Internal Revenue Code of 1986,
as amended. You may allocate contributions to the various investment divisions
of our Separate Account I (VARIABLE ACCOUNT OPTIONS, or individually, OPTION) or
to our Guaranteed Rate Options (GRO'S), or both.

    

   

Contributions you make to the Variable Account Options are invested in shares of
corresponding Portfolios of the Variable Insurance Products Fund (VIP), Variable
Insurance Products Fund II (VIP II), and Variable Insurance Products Fund III
(VIP III) (the PORTFOLIOS or PORTFOLIO). The Portfolios are part of the Fidelity
Investments(R) group of companies. The values allocated to the Options reflect
the investment performance of the Portfolios. The prospectus for the Portfolios
describes each one's investment objectives, policies and risks. The thirteen
Variable Account Options invest in the following portfolios:

The money you contribute to a GRO grows at a fixed interest rate that we declare
at the beginning of the duration you select. A MARKET VALUE ADJUSTMENT will be
made for withdrawals, surrenders, transfers and certain other transactions made
before your GRO Account expires. However, your value under a GRO Account can't
be decreased below an amount equal to your contribution plus interest compounded
at an annual effective rate of 3% (MINIMUM VALUE). Withdrawal charges and an
annual administrative charge may apply, which may invade principal.

THIS PROSPECTUS DOES NOT CONSTITUTE AN OFFERING IN ANY JURISDICTION IN WHICH
SUCH OFFERING MAY NOT LAWFULLY BE MADE. NO PERSON IS AUTHORIZED TO MAKE ANY
REPRESENTATIONS IN CONNECTION WITH THIS OFFERING OTHER THAN THOSE CONTAINED IN
THIS PROSPECTUS.

    

<PAGE>

   

PART 1 - SUMMARY

    

   

YOUR VARIABLE ANNUITY CONTRACT

    

   

In this prospectus, "we," "our" and "us" mean National Integrity Life Insurance
Company (NATIONAL INTEGRITY), a subsidiary of ARM Financial Group, Inc. (ARM).
The terms "you" and "your" mean the Annuitant, the person upon whose life the
Annuity Benefit and the Death Benefit are based, usually the Owner of the
contract. If the Annuitant doesn't own the contract, all of the rights under the
contract belong to the Owner until annuity payments begin. If a Joint Owner is
named, the Owners share the contract rights. Contract changes or any
transactions allowed under the Contract require both Owners' signatures. The
rules governing distribution at death apply when the first Owner dies. See Part
7, "Distribution-at-Death Rules."

    

   

You can invest for retirement by buying a GrandMaster III contract if you
properly complete a Customer Profile form (an application or enrollment form may
be required in some states) and make a minimum initial contribution. Because the
premium is flexible, your future contributions can be any amount you choose, as
long as it is above the minimum required contribution, discussed below.

    

   

The latest your endowment or "retirement date" can be is your 90th birthday,
unless your state law requires it to be a different date, or unless you specify
an earlier date.

    

   

YOUR BENEFITS

    

   

Your contract has an Account Value, an annuity benefit, and a death benefit.
These benefits are described in more detail below.

    

   

Your benefits under a contract may be controlled by the usual rules for taxation
of annuities, including the deferral of taxes on your investment growth until
you actually make a withdrawal. The contract also can provide your benefits
under certain tax-favored retirement programs, which may be subject to special
eligibility and contribution rules. See Part 7, "Tax Aspects of the Contracts"
and the Statement of Additional Information for detailed information.

    

   

HOW YOUR CONTRACT IS TAXED

    

   

Under the current tax laws, any increases in the value of your contributions
won't be considered part of your taxable income until you make a withdrawal.

    

   

YOUR CONTRIBUTIONS

    

   

The minimum initial contribution is $1,000. Contributions after your first one
can be as little as $100. Some tax-favored retirement plans allow smaller
contributions. See "Contributions Under Your Contract" in Part 5.

    

   

YOUR INVESTMENT OPTIONS

    

   

You may have your contributions placed in the Variable Account Options or the
GRO's, or place part of your contributions in each of them. The Variable Account
Options and the GRO's are together referred to as the INVESTMENT OPTIONS. You
may have money in as many as nine Investment Options at any one time. See
"Contributions Under Your Contract" in Part 5. To select Investment Options most
suitable for you, see Part 3, "Your Investment Options."

    

   

The Variable Account Options invest in shares of investment portfolios of mutual
funds. Each investment portfolio is referred to as a PORTFOLIO. The investment
goal of each Variable Account Option and its corresponding Portfolio is the
same. For example, if your investment goal is to save money for retirement, you
might choose a GROWTH oriented Variable Account Option, which invests in GROWTH
Portfolios. Your value in a Variable Account Option will vary with the
performance of the corresponding Portfolio. For a full description of the
Portfolios, see the Portfolios' prospectus and Statement of Additional
Information.

    

<PAGE>

   

ACCOUNT VALUE, ADJUSTED ACCOUNT VALUE AND CASH VALUE

    

   

Your ACCOUNT VALUE consists of the value of your GRO's added to the value of
your Variable Account Options. Your ADJUSTED ACCOUNT VALUE is your Account
Value, as increased or decreased (but not below the Minimum Value) by any Market
Value Adjustments. Your CASH VALUE is equal to your Adjusted Account Value,
minus any contingent withdrawal charge and minus the pro rata portion of the
annual administrative charge, if it applies. See "Charges and Fees" below.

    

   

TRANSFERS

    

   

You may transfer all or any part of your Account Value among the Investment
Options, although there are some restrictions that apply. You can find these in
Part 5, "Transfers." Any transfer must be for at least $250 and may be arranged
through our telephone transfer service. Transfers may also be made among certain
investment options under special services we offer to dollar cost average or
rebalance your investment in the Variable Account Options. See Part 8, "Dollar
Cost Averaging," "Customized Asset Rebalancing" and "Asset Allocation and
Rebalancing Program. If you make more than twelve transfers between your
Investment Options in one contract year, your account can be charged up to $20
for each transfer.

    

   

CHARGES AND FEES

    

   

If your Account Value is less than $50,000 as of the last day of any contract
year before your Retirement Date, an annual administrative expense charge of $30
is deducted from your Account.

    

   

A daily charge at an annual rate of 1.35% is deducted from the Account Value of
each of you Variable Account Options to cover mortality and expense risks
(1.20%) and certain administrative expenses (.15%). The charge will never be
greater than this. For more information, see Part 4, "Deductions and Charges."

    

   

Investment advisory fees and other expenses are deducted from amounts the
Separate Account invests in the Portfolios. Fidelity Management and Research
Company receives investment management fees from the Portfolios based on the
average net assets of each Portfolio. Advisory fees can't be increased without
the consent of shareholders. See "Table of Annual Fees and Expenses" below and
"The Portfolios' Investment Adviser" in Part 3.

    

   

WITHDRAWALS

    

   

You may make any number of withdrawals from your contract as often as you wish.
Each withdrawal must be for at least $300. You may withdraw up to 10% of your
account value each year with no withdrawal charges. After the first 10%, there
will be a charge for any withdrawals you make, based upon the length of time
your money has been in your account. See "Contingent Withdrawal Charge" in Part
4.

    

   

YOUR INITIAL RIGHT TO REVOKE

    

   

You can cancel your contract within ten days after you receive it by returning
it to our Administrative Office. We will extend the ten-day period as required
by law in some states. If you cancel your contract, we'll return your entire
contribution, with adjustments made for any investment gain or loss experienced
by the Variable Account Option from the date you purchased it until the date we
receive your cancelled contract, including any charges deducted. If your state
requires, we'll return all of your contributions without any adjustment. We'll
return the amount of any contribution to the Guaranteed Rate Options upon
cancellation.

    

   

RISK/RETURN SUMMARY: INVESTMENTS AND RISKS

    

   

VARIABLE ANNUITY INVESTMENT GOALS

    

   

The investment goals of the GrandMaster III Variable Annuity are protecting your
investment, building for retirement and providing future income. We strive to
achieve these goals through extensive portfolio diversification and superior
portfolio management.

    

<PAGE>

   

RISKS

    

   

An investment in any of the Variable Account Options carries with it certain
risks, including the risk that the value of your investment will decline and you
could lose money. This could happen if one of the issuers of the stocks becomes
financially impaired or if the stock market as a whole declines. Because most of
the Variable Account Options are in common stocks, there's also the inherent
risk that holders of common stock generally are behind creditors and holders of
preferred stock for payments in the event of the bankruptcy of a stock issuer.

    

   

For a complete discussion of the risks associated with an investment in any
particular Variable Account Option, see the prospectus of the corresponding
Portfolio.

    

   

YEAR 2000

    

   

Many computer programs are written so that only the last two digits of the year
are read. Because of this, many computer systems will read the year 2000 as
1900. This could cause many programs to malfunction. National Integrity is
evaluating, on an ongoing basis, its computer systems and the systems of other
companies on which we rely, to determine if they'll function properly, and make
the transition from 1999 to 2000 smoothly. These activities are designed to
ensure that there is no adverse effect on our business operations. While we've
been working very hard to make sure that this process will be problem-free, we
can't guarantee that there won't be some Year 2000 problems experienced by our
systems and we can't make any representations or guarantees that the outside
sources on which we rely will be ready to make a smooth transition to Year 2000
with their systems.

(1) See "Deductions and Charges - Contingent Withdrawal Charge" in Part 4. You
have a free withdrawal of up to 10% of the Account Value in any contract year or
the investment gain under the contract during the previous contract year,
whichever is greater, minus withdrawals during the current contract year.

    

   

(2) After the first twelve transfers during a contract year, we can charge a
transfer fee of $20 for each transfer. This charge doesn't apply to transfers
made for dollar cost averaging, or asset rebalancing. See "Deductions and
Charges - Transfer Charge" in Part 4.

    

   

(3)  See "Deductions and Charges - Separate Account Charges" in Part 4.

    

   

(4) Part of the brokerage commissions that certain Portfolios pay was used to
reduce the Portfolios' expenses. In addition, certain Portfolios have arranged
with their custodian to use uninvested cash balances to reduce custodian
expenses. Without these reductions, the total operating expenses presented in
the table would have been .58% for VIP Equity-Income Portfolio, .68% for VIP
Growth Portfolio, .91% for VIP Overseas Portfolio, .64% for VIP II Asset Manager
Portfolio, .70% for VIP II Contrafund Portfolio, .73% for VIP II Asset Manager:
Growth Portfolio, .58% for VIP III Balanced Portfolio, .71% for VIP III Growth
Opportunities Portfolio, and .61% for VIP III Growth and Income Portfolio.

    

   

(5) The investment adviser agreed to reimburse part of VIP II Index 500
Portfolio's expenses during the period. Without this reimbursement, the
Portfolio's management fee, other expenses and total expenses would have been
 .28%, .11%, and .39%, respectively.

   These examples assume that all of the fixed charges of the Separate Account
and of the investment advisory fees and other expenses of the Portfolios will
continue as they were for their most recent fiscal year or estimated expenses
(after reimbursement), if applicable. ACTUAL PORTFOLIO EXPENSES MAY BE MORE OR
LESS. The annual rate of return assumed in the examples isn't an estimate or
guarantee of future investment performance. The table assumes an estimated
$40,000 average contract value, so that the administrative charge per $1,000 of
net asset value in the Separate Account is $0.75. Such per $1,000 charge would
be higher for smaller Account Values and lower for higher values.

    

   

The table and examples above are to help you understand the various costs and
expenses that apply to your contract. These tables show expenses of the Separate
Account as well as those of the Portfolios. Premium taxes may also apply when
you receive a payout of your contributions.

    

   

CONDENSED FINANCIAL INFORMATION FOR THE SEPARATE ACCOUNT IS PROVIDED IN APPENDIX

PART 2 - NATIONAL INTEGRITY AND THE SEPARATE ACCOUNT

    

   

NATIONAL INTEGRITY LIFE INSURANCE COMPANY

    

   

National Integrity is a stock life insurance company organized under the laws of
New York. Our home office is located in Goshen, New York. We are authorized to
sell life insurance and annuities in eight states and the District of Columbia.
We sell flexible premium annuities with underlying investment options other than
the Portfolios, and fixed single premium annuities. We also provide
administrative and investment support for products designed, underwritten and
sold by other companies.

    

   

National Integrity is a subsidiary of ARM Financial Group, Inc., which
specializes providing retail and institutional customers with products and
services designed for long-term savings and retirement planning. ARM is a
publicly traded company listed on the New York Stock Exchange under the symbol
"ARM." At December 31, 1998, ARM had $9.9 billion of assets under management.

    

   

THE SEPARATE ACCOUNT AND THE VARIABLE ACCOUNT OPTIONS

    

   

The Separate Account is established and maintained under the insurance laws of
the State of New York. It is a unit investment trust registered with the
Securities and Exchange Commission (the SEC) under the Investment Company Act of
1940 (1940 ACT). A unit investment trust is a type of investment company. SEC
registration doesn't mean that the SEC is involved in any way in supervising the
management or investment policies of the Separate Account. Each Variable Account
Option invests in shares of a corresponding Portfolio of the Portfolios. We may
establish additional Options from time to time. The Variable Account Options
currently available to you are listed in Part 3, "Your Investment Options."
Prior to September 3, 1991, the Portfolios invested in shares of corresponding
portfolios of Prism Investment Trust.

    

   

ASSETS OF OUR SEPARATE ACCOUNT

    

   

Under New York law, we own the assets of our Separate Account and use them to
support the variable portion of yours and other variable annuity contracts.
Annuitants under other variable annuity contracts participate in the Separate
Account in proportion to the amounts in their contracts. We can't use the
Separate Account's assets supporting the variable portion of these variable
contracts to satisfy liabilities arising out of any of our other businesses.
Under certain unlikely circumstances, one Variable Account Option may be liable
for claims relating to the operations of another Option.

    

   

Income, gains and losses, whether or not realized, from assets allocated to the
Separate Account are credited to or charged against the Separate Account without
regard to our other income, gains or losses. We may allow charges owed to us to
stay in the Separate Account, and in that way, we can participate
proportionately in the Separate Account. Amounts in the Separate Account in
excess of reserves and other liabilities belong to us, and we may transfer them
to our general account.

    

   

CHANGES IN HOW WE OPERATE

    

   

We can change how we or our Separate Account operate, subject to your approval
when required by the 1940 Act or other applicable law or regulation. We'll
notify you if any changes result in a material change in the underlying
investments of a Variable Account Option. WE MAY:

    

   

 -  add Options to, or remove Options from, our Separate Account, combine two or
    more Options within our Separate Account, or withdraw assets relating to
    your contract from one Option and put them into another;

    

   

 -  register or end the registration of the Separate Account under the 1940 Act;

    

   

 -  operate our Separate Account under the direction of a committee or discharge
    a committee at any time (the committee may be composed of a majority of
    persons who are "interested persons" of National Integrity under the 1940
    Act);

    

   
     -    restrict or eliminate any voting rights of Owners or others who have
          voting rights that affect our Separate Account;

    

   

     -    cause one or more Options to invest in a mutual fund other than or in
          addition to the Portfolios;

    

<PAGE>

   

     -    operate our Separate Account or one or more of the Options in any
          other form the law allows, including a form that allows us to make
          direct investments. We may make any legal investments we wish. In
          choosing these investments, we'll rely on our own or outside counsel
          for advice.

THE PORTFOLIOS

    

   

Management fees and other expenses deducted from each Portfolio are described in
that Portfolio's prospectus. FOR A PROSPECTUS CONTAINING MORE COMPLETE
INFORMATION ON ANY PORTFOLIO, CALL OUR ADMINISTRATIVE OFFICE TOLL-FREE AT
1-800-433-1778.

    

   

Each of the Portfolios is an open-end diversified management investment company
registered with the SEC.

    

   

The Portfolios serve as investment vehicles for variable annuity and variable
life contracts of insurance companies. Shares of the Portfolios currently are
available to the separate accounts of a number of insurance companies, both
affiliated and unaffiliated with Fidelity Management or Integrity. The Board of
Trustees of each of the Portfolios is responsible for monitoring the Fund for
any material irreconcilable conflict between the interests of the policyowners
of all separate accounts investing in the Portfolio and determining what action,
if any, should be taken in response. If we believe that a Portfolio's response
to any of those events doesn't adequately protect our contract owners, we'll see
to it that appropriate and available action is taken. See "The Fund and the
Fidelity Organization" in the Portfolios' prospectus for a further discussion of
the risks associated with the offering of shares to our Separate Account and the
separate accounts of other insurance companies.

    

   

THE PORTFOLIOS' INVESTMENT ADVISER. Fidelity Management & Research Company
(FIDELITY MANAGEMENT) is a registered investment adviser under the Investment
Advisers Act of 1940. It serves as the investment adviser to each Portfolio.
Bankers Trust Company ("BT") is the VIP II Index 500 Portfolio's sub-adviser.

Trust New York Corporation.

    

   

INVESTMENT OBJECTIVES OF THE PORTFOLIOS. Below is a summary of the investment
objectives of the Portfolios of Fidelity's VIP Funds. There are no guarantees
that a Portfolio will be able to achieve its objective. YOU SHOULD READ
FIDELITY'S VIP FUNDS' PROSPECTUS CAREFULLY BEFORE INVESTING.

    

   

                           VIP MONEY MARKET PORTFOLIO

preserving capital and providing liquidity. It invests only in high-quality,
U.S. dollar denominated money market securities of domestic and foreign issuers,
such as certificates of deposit, obligations of governments and their agencies,
and commercial paper and notes.

    

   
                            VIP HIGH INCOME PORTFOLIO
    

   

VIP High Income Portfolio seeks a high current income by investing primarily in
high-yielding, lower rated, fixed-income securities, while also considering
growth of capital. It normally invests at least 65% of its total assets in
income-producing debt securities and preferred stocks, including convertible
securities, and up to 20% in common stocks and other equity securities. In view
of the types of securities in which this Portfolio invests, you should read the
complete risk disclosure for this Portfolio in its prospectus before investing
in it.

    

   
                           VIP EQUITY-INCOME PORTFOLIO
    

   

VIP Equity-Income Portfolio seeks reasonable income. The Portfolio will also
consider the potential for capital appreciation. The Portfolio seeks a yield
which exceeds the composite yield on the securities comprising the S&P 500. FMR
normally invests at least 65% of the Portfolio's total assets in
income-producing equity securities.

    

<PAGE>

   
                              VIP GROWTH PORTFOLIO
    

   

VIP Growth Portfolio seeks capital appreciation. FMR invests the Portfolio's
assets in companies FMR believes have above-average growth potential. Growth may
be measured by factors such as earnings or revenue. Companies with high growth
potential tend to be companies with higher than average price/earnings (P/E)
ratios. Companies with strong growth potential often have new products,
technologies, distribution channels or other opportunities for have a strong
industry market position. The stocks of these companies are often called
"growth" stocks.

    

   
                             VIP OVERSEAS PORTFOLIO
    

   

VIP Overseas Portfolio seeks long-term growth of capital primarily through
investments in foreign securities. It normally invests at least 65% of its
assets in foreign securities.

    

   
                     VIP II INVESTMENT GRADE BOND PORTFOLIO
    

   

VIP II Investment Grade Bond Portfolio seeks as high a level of current income
while preserving capital by investing in a broad range of investment-grade
fixed-income securities.

    

   
                         VIP II ASSET MANAGER PORTFOLIO

the long-term by allocating its assets among stocks, bonds and short-term money
market instruments.

    

   
                           VIP II INDEX 500 PORTFOLIO
    

   

VIP II Index 500 Portfolio seeks to provide investment results that correspond
to the total return (i.e., the combination of capital changes and income) of
common stocks publicly traded in the United States. In seeking this objective,
the Portfolio attempts to duplicate the composition and total return of the
Standard & Poor's 500 Composite Stock Price Index while keeping transaction
costs and other expenses low.

    

   
                           VIP II CONTRAFUND PORTFOLIO
    

   

VIP II Contrafund Portfolio seeks long-term capital appreciation. FMR normally
invests the Portfolio's assets primarily in common stocks. FMR invests the
Portfolio's assets in securities of companies whose value FMR believes is not
fully recognized by the public. The types of companies in which the Portfolio
may invest include companies experiencing positive fundamental change such as a
new management team or product launch, a significant cost-cutting initiative, a
merger or acquisition, or a reduction in industry capacity that should lead to
improved pricing; companies whose earning potential has increased or is expected
to increase more than generally perceived; companies that have enjoyed recent
market popularity but which appear to have temporarily fallen out of favor for
reasons that are considered non-recurring or short-term; and companies that are
undervalued in relation to securities of other companies in the same industry.

in a diversified portfolio of equity and fixed-income securities. It uses a

income securities.

    

   
                        VIP III GROWTH & INCOME PORTFOLIO

of current income and capital appreciation. FMR normally invests a majority of
the Portfolio's assets in common stocks with a focus on those that pay current
dividends and show potential for capital appreciation. FMR may also invest the
Portfolio's assets in bonds, including lower-quality debt securities, as well as
stocks that are not currently paying dividends, but offer prospects for future
income or capital appreciation.

OF THE 1933 ACT OR THE 1940 ACT. ACCORDINGLY, WE HAVE BEEN ADVISED THAT THE
STAFF OF THE SECURITIES AND EXCHANGE COMMISSION HASN'T REVIEWED THE DISCLOSURE
IN THIS PROSPECTUS RELATING TO THE GROS OR THE GENERAL ACCOUNT. DISCLOSURES
REGARDING THE GROS OR THE GENERAL ACCOUNT MAY, HOWEVER, BE SUBJECT TO CERTAIN
GENERALLY APPLICABLE PROVISIONS OF THE FEDERAL SECURITIES LAWS RELATING TO THE
ACCURACY AND COMPLETENESS OF STATEMENTS MADE IN PROSPECTUSES.

    

   

We offer GROs with durations of three, five, seven and ten years. We can change
the durations available from time to time. When you put money in a GRO, that
locks in a fixed effective annual interest rate that we declare (GUARANTEED
INTEREST RATE) for the duration you select (your GRO ACCOUNT). The duration of
your GRO Account is the GUARANTEE PERIOD. Each contribution or transfer to a GRO
establishes a new GRO Account for the duration you choose at the then-current
Guaranteed Interest Rate we declare. We won't declare an interest rate less than
3%. Each GRO Account expires at the end of the duration you have selected. See
"Renewals of GRO Accounts" below. All contributions you make to a GRO are placed
in a non-unitized separate account. Values and benefits under your contract
attributable to GROs are guaranteed by the reserves in our GRO separate account
as well as by our General Account.

    

   

The value of each of your GRO Accounts is referred to as a GRO VALUE. The GRO
Value at the expiration of the GRO Account, assuming you haven't transferred or
withdrawn any amounts, will be the amount you put in plus interest at the
Guaranteed Interest Rate. We credit interest daily at an effective annual rate
equal to the Guaranteed Interest Rate. We allocate interest at the end of each
contract year and at the time of any transfer, full or partial withdrawal,
payment of a death benefit or purchase of any annuity benefit.

    

   

We may declare a higher rate of interest in the first year for any Contribution
allocated to a GRO that exceeds the Guaranteed Interest Rate credited during the
rest of the Guarantee Period (ENHANCED RATE). This Enhanced Rate will be
guaranteed for the Guaranteed Period's first year and declared at the time of
purchase. We can declare and credit additional interest based on Contribution,
Account Value, withdrawal dates, economic conditions or on any other lawful,
nondiscriminatory basis (ADDITIONAL INTEREST). Any Enhanced Rate and Additional
Interest credited to your GRO Account will be separate from the Guaranteed
Interest Rate and not used in the Market Value Adjustment formula. THE ENHANCED
RATE OR ADDITIONAL INTEREST MAY NOT BE AVAILABLE IN CERTAIN STATES.

    

   

Each group of GRO Accounts of the same duration is considered one GRO. For
example, all of your three-year GRO Accounts are one GRO while all of your
five-year GRO Accounts are another GRO.

    

<PAGE>

   

You can get our current Guaranteed Interest Rates by calling our Administrative
Office.

    

   

ALLOCATIONS TO GROS CAN'T BE MADE UNDER CONTRACTS ISSUED IN CERTAIN STATES.

    

   

RENEWALS OF GRO ACCOUNTS. When a GRO Account expires, we'll set up a new GRO
Account for the same duration as your old one, at the then-current Guaranteed
Interest Rate, unless you withdraw your GRO Value or transfer it to another
Investment Option. We'll notify you in writing before your GRO Account expires.
You must tell us before the expiration of your GRO Accounts if you want to make
any changes.

    

   

The effective date of a renewal of a GRO Account will be the expiration date of
the old GRO Account. You will receive the Guaranteed Interest Rate that is in
effect on that date. If a GRO Account expires and it can't be renewed for the
same duration, the new GRO Account will be set up for the next shortest
available duration. For example, if your expiring GRO Account was for 10 years
and when it expires, we don't offer a 10-year GRO, but we do offer a seven-year
GRO, your new one will be for seven years. If you want something different, you
can tell us within 30 days before the GRO Account expires. You can't choose, and
we won't renew a GRO Account that expires after your Retirement Date.

    

   

MARKET VALUE ADJUSTMENTS. A MARKET VALUE ADJUSTMENT is an adjustment, either up
or down, that we make to your GRO Value if you make an early withdrawal or
transfer from your GRO Account. A Market Value Adjustment will be made for each
transaction made from a GRO Account other than your free withdrawals or those
made within 30 days before the expiration of the Account. There will be no
Market Value Adjustment made for a death benefit. The market adjusted value may
be higher or lower than the GRO Value, but will never be less than the MINIMUM
VALUE. Minimum Value is an amount equal to your contribution to the GRO Account
plus 3% interest, compounded annually, less previous withdrawals and less any
applicable contingent withdrawal charges. The Minimum Value for partial
withdrawals or transfers will be calculated on a pro-rata basis. Withdrawal
charges and the administrative expense charge could take away part of your
principal.

    

   

The Market Value Adjustment we make to your GRO Account is based on the changes
in our Guaranteed Interest Rate. If our Guaranteed Interest Rate has increased
since the time of your investment, the Market Value Adjustment will reduce your
GRO Value (but not below the Minimum Value). On the other hand, if our
Guaranteed Interest Rate has decreased since the time of your investment, the
Market Value Adjustment will increase your GRO Value.

    

   

The Market Value Adjustment (MVA) for a GRO Account is determined under the
following formula:

    

   

    MVA =  GRO Value x [(1 + A)N/12 / (1 + B + .0025)N/12 - 1],  where

    

   

     A is the Guaranteed Interest Rate being credited to the GRO Account subject
     to the Market Value Adjustment,

    

   

     B is the current Guaranteed Interest Rate, as of the date of the Market
     Value Adjustment, for current allocations to a GRO Account, the length of
     which is equal to the number of whole months remaining in your GRO Account.
     Subject to certain adjustments, if that remaining period isn't equal to an
     exact period for which we have declared a new Guaranteed Interest Rate, B
     will be determined by a formula that finds a value between the Guaranteed
     Interest Rates for GRO Accounts of the next highest and next lowest
     durations.

    

   

     N is the number of whole months remaining in your GRO Account.

    

   

For contracts issued in certain states, the formula above will be adjusted to

comply with state requirements.

    

   

If the remaining term of your GRO Account is 30 days or less, the Market Value
Adjustment for your GRO Account will be zero. If for any reason we are no longer
declaring current Guaranteed Interest Rates, then to determine B we will use the
yield to maturity of United States Treasury Notes with the same remaining term
as your GRO Account, using a formula when necessary, in place of the current
Guaranteed Interest Rate or Rates.

    

   

For illustrations of the application of the Market Value Adjustment formula, see
Appendix B.

PART 4 - DEDUCTIONS AND CHARGES

    

   

SEPARATE ACCOUNT CHARGES

    

   

National Integrity deducts a daily expense amount from the unit value an amount
equal to an effective annual rate of 1.35% of the Account Value in the Variable
Account Options. This daily expense rate can't be increased without your
consent.

    

   

     Of the 1.35% total charge, .15% of the value of each Variable Account
Option is used to reimburse us for administrative expenses not covered by the
annual administrative charge described below. The remaining 1.20% is deducted
for National Integrity's assuming the expense risk (.85%) and the mortality risk
(.35%) under the contract. The expense risk is the risk that our actual expenses
of administering the contracts will exceed the annual administrative expense
charge. Mortality risk, as used here, refers to the risk National Integrity
takes that annuitants, as a class of persons, will live longer than estimated
and National Integrity will be required to pay out more annuity benefits than
anticipated. The relative proportion of the mortality and expense risk charges
may be changed, but the total 1.20% effective annual risk charge can't be
increased.

    

   

National Integrity may realize a gain from these daily charges if they aren't
needed to meet the actual expenses incurred.

    
         ANNUAL ADMINISTRATIVE CHARGE
   

If your Account Value is less than $50,000 on the last day of any contract year
before your Retirement Date, National Integrity charges an annual administrative
charge of $30. This charge is deducted pro-rata from your Account Value in each
Investment Option. The part of the charge deducted from the Variable Account
Options will reduce the number of units credited to you. The part of the charge
deducted from the GROs is withdrawn in dollars. The annual administrative charge
is pro-rated in the event of the Annuitant's retirement, death, or termination
of a contract during a contract year.

    
    
   

REDUCTION OR ELIMINATION OF SEPARATE ACCOUNT OR ADMINISTRATIVE CHARGES

    

   

     We can reduce or eliminate the separate account or administrative charges
for individuals or groups of individuals if it saves us expenses. We may do this
based on the size and type of the group and the amount of the contributions.

    

   

     We won't unlawfully discriminate against any person or group if we reduce
or eliminate these charges.

    

   

    PORTFOLIO CHARGES
    
    
   

     The Separate Account buys shares of the Portfolios at net asset value. That
price reflects investment advisory fees and other direct expenses that have
already been deducted from the assets of the Portfolios. The amount charged for
investment management can't be increased without the approval of the
shareholders.

    

   

    STATE PREMIUM TAX DEDUCTION
    

   

National Integrity won't deduct state premium taxes from your contributions
before investing them in the Investment Options, unless required to by your
state law. If the Annuitant elects an annuity benefit, we'll deduct any
applicable state premium taxes from the amount available for an annuity benefit.
State premium taxes currently range up to 4%.

    

<PAGE>

   

    CONTINGENT WITHDRAWAL CHARGE

    

   

We don't deduct sales charges when you make a contribution to the contract.
However, contributions withdrawn may be subject to a withdrawal charge of up to
7%. As shown below, the charge varies, depending upon the "age" of the
contributions included in the withdrawal- that is, the number of years that have
passed since each contribution was made. The maximum percentage of 7% would
apply if the entire amount of the withdrawal consisted of contributions made
during your current contribution year. We don't deduct withdrawal charges when
you withdraw contributions made more than six years prior to your withdrawal. To
calculate the withdrawal charge, (1) the oldest contributions will be treated as
the first withdrawn and more recent contributions next, and (2) partial
withdrawals up to the free withdrawal amount aren't considered a withdrawal. For
partial withdrawals, the total amount deducted from your Account will include
the withdrawal amount requested, any Market Value Adjustment that applies, and
any withdrawal charge and administrative expense charge that apply, so that the
net amount you receive will be the amount you requested.

    

<PAGE>

   

     You may take up to the greater of (i) 10% of your account value and (ii)
any investment gain during the prior contract year, less any earlier withdrawal
in the same year, without any contingent withdrawal charge or Market Value
Adjustment. This is referred to as your "free withdrawal." Investment gain is
calculated as the increase in the Account Value during the prior contract year,
minus contributions during that year, plus withdrawals made during the year. If
you don't take any free withdrawals in one year, you can't add it to the next
year's free withdrawal. If you aren't 59-1/2, federal tax penalties may apply.

</TABLE>

    

   

     We won't deduct a contingent withdrawal charge if you use the withdrawal to
buy from National Integrity either an immediate annuity benefit with life
contingencies or an immediate annuity without life contingencies with a
restricted prepayment option that provides for level payments over five or more
years. Similarly, we won't deduct a charge if the Annuitant dies and the
withdrawal is made by the Annuitant's beneficiary. See "Death Benefits and
Similar Benefit Distributions" in Part 5.

    

   

     Unless you tell us otherwise, we will make withdrawals (including any
applicable charges) from the Investment Options in the same proportion that you
contributed to them. For example, if you have your contributions put into four
different Investment Options, your withdrawal will be taken in equal quarters
from each Account. You must withdraw a total of at least $300.

    

   

REDUCTION OR ELIMINATION OF THE CONTINGENT WITHDRAWAL CHARGE

    
    
   

     We can reduce or eliminate the contingent withdrawal charge for individuals
or a group of individuals it saves us expenses. We may do this based on the size
and type of the group and the amount of the contribution or whether there is
some relationship with National Integrity. Examples of these relationships would
include being an employee of National Integrity or an affiliate, receiving
distributions or making internal transfers from other contracts issued by
National Integrity, or making transfers of amounts held under qualified plans
sponsored by National Integrity or an affiliate. We won't unlawfully
discriminate against any person or group if we reduce or eliminate the
contingent withdrawal charge.

    
    
   

TRANSFER CHARGE

    
    
   

If you make more than twelve transfers among your Investment Options during one
contract year, we may charge your account up to $20 for each additional transfer
during that year. Transfer charges don't apply to transfers under (i) Dollar
Cost Averaging, (ii) Customized Asset Rebalancing, (iii) Asset Allocation and
Rebalancing, nor do these transfers count toward the twelve free transfers you
may make in a contract year.

    
    
   

HARDSHIP WAIVER

    
    
   

We can waive withdrawal charges on full or partial withdrawal requests of $1,000
or more under a hardship circumstance. We can also waive the Market Value
Adjustment on any amounts withdrawn from the GRO Accounts. Hardship
circumstances include the Owner's (1) confinement to a nursing home, hospital or
long term care facility, (2) diagnosis of terminal illness with any medical
condition which would result in death or total disability, and (3) unemployment.
We can require reasonable notice and documentation including, but not limited
to, a physician's certification and Determination Letter from a State Department
of Labor. Some of the hardship circumstances listed above may not apply in some
states, and, in other states, may not be available at all.

    

<PAGE>
    
   

TAX RESERVE

    
    
   

We can make a charge in the future for taxes or for reserves set aside for
taxes, which will reduce the investment experience of the Variable Account
Options.

    
    
   

PART 5 - TERMS OF YOUR VARIABLE ANNUITY

    
    
   

CONTRIBUTIONS UNDER YOUR CONTRACT

    
    
   

You can make contributions of at least $100 at any time up to the Annuitant's
Retirement Date. Your first contribution, however, can't be less than $1,000.
We'll accept contributions of at least $50 for salary allotment programs. We
have special rules for minimum contribution amounts for tax-favored retirement
programs.
See "Special Rules for Tax-Favored Retirement Programs" in Part 7.

    
    
   

We may limit the total contributions under one contract to $1,000,000 if you are
under age 76 or to $250,000 if you are over age 76. Once you reach eight years
before your Retirement Date, we may refuse to accept any contribution.
Contributions may also be limited by various laws or prohibited by National
Integrity for all Annuitants under the contract. If your contributions are made
under a tax-favored retirement program, we won't measure them against the
maximum limits set by law.

    
    
   

Contributions are applied to the various Investment Options you select and are
used to pay annuity and death benefits. Each contribution is credited as of the
date we have RECEIVED it (as defined below) at our Administrative Office both
the contribution and instructions for allocation among the Investment Options,
PROVIDED THAT AT ANY TIME YOU MAY NOT HAVE MONEY IN MORE THAN NINE INVESTMENT
OPTIONS. In determining the nine Investment Options, each of your GRO Accounts
counts as one Investment Option. Wire transfers of federal funds are deemed
received on the day of transmittal if credited to our account by 3 p.m. Eastern
Time, otherwise they are deemed received on the next Business Day. Contributions
by check or mail are deemed received when they are delivered in good order to
our Administrative Office. A BUSINESS DAY is defined as any day that the New
York Stock Exchange is open.

    
    
   

You can change your choice of Investment Options at any time by writing to the
Administrative Office. The request should indicate your contract number and the
specific change you want to make, and you should sign the request. When the
Administrative Office receives it, the change will be effective for any
contribution that accompanies it and for all future contributions. We can also
accept changes by telephone transfer. See "Transfers" in Part 5.

    

<PAGE>

   

YOUR ACCOUNT VALUE

    
    
   

Your Account Value reflects various charges. See Part 4, "Deductions and
Charges." Annual deductions are made as of the last day of each contract year.
Withdrawal charges and Market Value Adjustments, if applicable, are made as of
the effective date of the transaction. Charges against our Separate Account are
reflected daily. Any amount allocated to a Variable Account Option will go up or
down in value depending on the investment experience of that Option. The value
of contributions made to the Variable Account Options isn't guaranteed. The
value of your contributions made to GROs is guaranteed, subject to any
applicable Market Value Adjustments. See "Guaranteed Rate Options" in Part 3.

    
    
   

YOUR PURCHASE OF UNITS IN OUR SEPARATE ACCOUNT

    
    
   

Allocations to the Variable Account Options are used to purchase units. On any
given day, the value you have in a Variable Account Option is the unit value
multiplied by the number of units credited to you in that Option.
The units of each Variable Account Option have different unit values.

    
    
   

The number of units purchased or redeemed (sold) in any Variable Account Option
is calculated by dividing the dollar amount of the transaction by the Option's
unit value, calculated after the close of business that day. The number of units
for a Variable Account Option at any time is the number of units purchased less
the number of units redeemed. The value of units fluctuates with the investment
performance of the corresponding Portfolios, which in turn reflects the
investment income and realized and unrealized capital gains and losses of the
Portfolios, as well as its expenses. The unit values also change because of
deductions and charges we make to our Separate Account. The number of units
credited to you, however, won't vary because of changes in unit values. Units of
a Variable Account Option are purchased when you make new contributions or
transfer contributions you made before to that Option. Units are redeemed when
you make withdrawals or transfer amounts out of a Variable Account Option. We
also redeem units to pay the death benefit when the Annuitant dies and to pay
the annual administrative charge.

    
    
   

HOW WE DETERMINE UNIT VALUE

    
    
   

We determine unit values for each Variable Account Option on the Valuation Date.
The Valuation Date for purposes of determining unit values is 4 p.m. Eastern
Time on each day the New York Stock Exchange is open for business.

    
    

   

The unit value of each Variable Account Option for any day on which we determine
unit values is equal to the unit value for the last day on which a unit value
was determined multiplied by the net investment factor for that Option on the
current day. We determine a NET INVESTMENT FACTOR for each Option as follows:

    
    
   

  -     First, we take the value of the shares belonging to the Option in the
        corresponding Portfolio at the close of business that day (before giving
        effect to any transactions for that day, such as contributions or
        withdrawals). For this purpose, we use the share value reported to us by
        the Portfolios.

    
    
   
     -    Next, we add any dividends or capital gains distributions by the
          Portfolio on that day.

    
    

   
     -    Then, we charge or credit for any taxes or amounts set aside as a
          reserve for taxes.


    
    
   

     -    Then, we divide this amount by the value of the amounts in the Option
          at the close of business on the last day on which a unit value was
          determined (after giving effect to any transactions on that day).

    
    

   
     -    Finally, we subtract a daily asset charge for each calendar day since
          the last day on which a unit value was determined (for example, a
          Monday calculation will include charges for Saturday and Sunday). The
          daily charge is .00003721, which is an effective annual rate of 1.35%.
          This charge is for the mortality risk, administrative expenses and
          expense risk assumed by us under the contract.

    
    
   

Generally, this means that we adjust unit values to reflect what happens to the
Portfolio, and also for the mortality and expense risk charge and any charge for
administrative expenses or taxes.

    

<PAGE>
    
   

TRANSFERS

    
    
   

You may transfer your Account Value among the Variable Account Options and the
GROs, subject to National Integrity's transfer restrictions. Transfers to a GRO
must be to a newly elected GRO (i.e. to a GRO you haven't already purchased) at
the then-current Guaranteed Interest Rate, unless we agree otherwise. Transfers
you make from a GRO Account, except within 30 days before your GRO Account
expires, are subject to a Market Value Adjustment. See "Guaranteed Rate Options"
in Part 3. Transfers from GRO's will be made according to the order in which
money was originally allocated to the GRO.

    
    
   

The amount transferred must be at least $250 or, if less, the entire amount in
the Investment Option. You have twelve free transfers during a contract year.
After those twelve transfers, a charge of up to $20 may apply to each additional
transfer during that contract year. No charge will be made for transfers under
our Dollar Cost Averaging, Customized Asset Rebalancing, for the Asset
Allocation and Rebalancing Program programs, described in Part 8. Once annuity
payments begin, transfers aren't permitted.

    
    
   

You may request a transfer by writing to our Administrative Office. Each request
for a transfer must specify the contract number, the amounts to be transferred
and the Investment Options to and from which the amounts are to be transferred.
Transfers may also be arranged through our telephone transfer service if you
have established a Personal Identification Number (PIN CODE). We'll honor
telephone transfer instructions from any person who provides correct identifying
information. We aren't responsible in the event of a fraudulent telephone
transfer if it is believed to be genuine in accordance with these procedures.
You bear the risk of loss if unauthorized persons make transfers on your behalf.

    
    
   

A transfer request is effective as of the Business Day our Administrative Office
receives it. A transfer request doesn't change the allocation of current or
future contributions among the Investment Options. Telephone transfers may be
requested from 9:00 a.m. - 5:00 p.m., Eastern Time, on any day we're open for
business. You'll receive the Variable Account Options' unit values as of the
close of business on the day you call. Transfer requests received after 4:00
p.m. Eastern Time (or the close of the New York Stock Exchange, if earlier) will
be processed using unit values as of the close of business on the next Business
Day after the day you call. All transfers will be confirmed in writing.

    
    
   

Transfer requests submitted by agents or market timing services that represent
multiple policies will be processed no later than the next Business Day after
our Administrative Office receives the requests.

    
    
   

WITHDRAWALS

    
    
   

You may make any number of withdrawals as often as you wish. Each withdrawal
must be for at least $300. The money will be taken from your Accounts in the
same proportions as you contributed it to them. For example, if your
contributions are divided in equal 25% shares among four Investment Options,
when you make a withdrawal, 25% of the money withdrawn will come from each of
your Investment Options. You can tell us if you want your withdrawal handled
differently. During the first six years of your contract, there is a contingent
withdrawal charge for any withdrawals other than your free withdrawals. The
charge starts at 7% and decreases depending on the age of your account. This
charge is in addition to any Market Value Adjustments made to early withdrawals
from GRO Accounts. Under some circumstances, the contingent withdrawal charge
and Market Value Adjustment may be waived.

    
    
   

When you make a partial withdrawal, the total amount deducted from your Account
Value will include the withdrawal amount requested plus any contingent
withdrawal charges and any Market Value Adjustments. The total amount that you
receive will be the total that you requested. Most of the withdrawals you make
before you are 59-1/2 years old are subject to a 10% federal tax penalty. If
your contract is part of a tax-favored plan, the plan may limit your
withdrawals. See "Tax Aspects of the Contracts" in Part 7.

    
    
   

ASSIGNMENTS

    
    
   

If your contract isn't part of a tax-favored program, you may assign the
contract before the Annuitant's Retirement Date. You can't, however, make a
partial assignment. An assignment of the contract may have adverse tax

    

<PAGE>
    
   

consequences. See Part 7, "Tax Aspects of the Contracts." We won't be bound by
an assignment unless it is in writing and our Administrative Office has received
it.

    
    
   

DEATH BENEFITS AND SIMILAR BENEFIT DISTRIBUTIONS

    
    
   

We'll pay a death benefit to the Annuitant's surviving beneficiary (or
beneficiaries, in equal shares) if the last Annuitant dies before annuity
payments have started. If the Annuitant dies at or over age 90 (or after the
Contract's 10th anniversary date, if later), the death benefit is the contract
account value at the end of the business day when we receive proof of death.
Similarly, if the Contract was issued on or after the youngest Annuitant's 86th
birthday, the death benefit is the contract account value at the end of the
business day when we receive proof of death.

    
    
   

For Contracts issued before the Annuitant's 86th birthday, if the Annuitant dies
before age 90 (or the Contract's 10th anniversary date, if later) before annuity
payments have started, the death benefit is the highest of:

    
    
   

          a)   the contract account value at the end of the business day when we
               receive proof of death;

    
    
   

          b)   the total of all contributions; and

    
    

   

          c)   the highest contract account value on any contract anniversary
               which occurred before the Annuitant's 81st birthday and before
               the Annuitant's death, plus any subsequent contributions;

    
    

   

each reduced on a pro rata basis for prior withdrawals (after being adjusted for
any applicable market value adjustments and/or charges). We'll determine the
amount of the reduction by dividing the amount of the withdrawal by the annuity
account value on the transaction date and multiplying this percentage by the
then current guaranteed minimum death benefit.

    
    
   

Death benefits and benefit distributions required because of a separate Owner's
death can be paid in a lump sum or as an annuity. If a benefit option hasn't
been selected for the beneficiary at the Annuitant's death, the beneficiary can
select an option.

    
    
   

The Owner selects the beneficiary of the death benefit. An Owner may change
beneficiaries by sending the appropriate form to the Administrative Office. If
an Annuitant's beneficiary doesn't survive the Annuitant, then the death benefit
is generally paid to the Annuitant's estate. No death benefit will be paid after
the Annuitant's death if there is a contingent Annuitant. In that case, the
contingent Annuitant becomes the new Annuitant under the contract.

    
    
   

The death benefit described above is retroactive to all contracts issued on or
after January 1, 1997.

    
    
   

ANNUITY BENEFITS

    
    
   

All annuity benefits under your contract are calculated as of the Retirement
Date you select. You can change the Retirement Date by writing to the
Administrative Office any time before the Retirement Date. The Retirement Date
can't be later than your 90th birthday or earlier, if required by law. Contract
terms that apply to the various retirement programs, along with the federal tax
laws, establish certain minimum and maximum retirement ages.

    
    
   

Annuity benefits may be a lump sum payment or paid out over time as an annuity.
A lump sum payment will provide the Annuitant with the Cash Value under the
contract, shortly after the Retirement Date. The amount applied toward the
purchase of an annuity benefit will be the Adjusted Account Value, except that
the Cash Value will be the amount applied instead if the annuity benefit doesn't
have a life contingency and either the term is less than five years or the
annuity can be commuted to a lump sum payment without a withdrawal charge
applying.

    
    
   

ANNUITIES

    
    
   

Annuity benefits can provide for fixed or variable payments, which may be made
monthly, quarterly, semi-annually or annually. Variable payments will be funded
through one or more Separate Account Divisions. For any annuity, the minimum
initial payment must be at least $20.

    
    
   

If you haven't already selected a form of annuity, within six months prior to
your Retirement Date we'll send you a notice form. You can tell us on the form
the type of annuity you want or confirm to us that we're to provide the 

    

<PAGE>

   

normal
form of annuity, as defined below. However, if we don't receive a completed form
from you on or before your Retirement Date, we'll extend the Retirement Date
until we receive your written instructions at our Administrative Office. During
this extension, the values under your contract in the various Investment Options
will remain invested in those options and amounts remaining in Variable Account
Options will continue to be subject to the investment risks associated with
those Options. However, your Retirement Date can't be extended beyond your 90th
birthday or earlier, if required by law. You'll receive a lump sum benefit if
you don't make an election by then.

    

   

We currently offer the following types of annuities:

    

    
   

The NORMAL FORM OF ANNUITY is a fixed life income annuity with 10 years of
payments guaranteed, funded through our General Account.

    
    
   

A PERIOD CERTAIN ANNUITY provides for fixed or variable payments, or both, to
the Annuitant or the Annuitant's beneficiary (the PAYEE) for a fixed period. The
amount is determined by the period selected. If the payee dies before the end of
the period selected, the payee's beneficiary may elect to receive the total
present value of future payments in cash.

    
    
   

A PERIOD CERTAIN LIFE ANNUITY provides for fixed or variable payments, or both,
for at least the period selected and thereafter for the life of the payee or the
payee and another annuitant under a joint and survivor annuity. You can't change
or redeem the annuity once payments have begun. If the payee (or the payee and
the other annuitant under a joint and survivor annuity) dies before the period
selected ends, the remaining payments will go to another named payee. That payee
can redeem the annuity and receive the present value of future guaranteed
payments in a lump sum.

    
    
   

A LIFE INCOME ANNUITY provides fixed payments for the life of the payee or for
the lives of the payee and another annuitant under a joint and survivor annuity.
Once a life income annuity is selected, the form of annuity can't be changed or
redeemed for a lump sum payment by the Annuitant or any payee.

    
    
   

ANNUITY PAYMENTS

    
    
   

Fixed annuity payments won't change and are based upon annuity rates provided in
your contract. The size of payments will depend on the form of annuity that was
chosen and, in the case of a life income annuity, on the payee's age (or payee
and a joint annuitant in the case of a joint and survivor annuity) and sex
(except under most tax-favored retirement programs). If our annuity rates then
in effect would yield a larger payment, those rates will apply instead of the
tables.

    
    
   

Variable annuity payments are funded only in the Separate Account Divisions
through the purchase of annuity units. The Variable Account Option or Options
selected can't be changed after annuity payments begin. The Statement of
Additional Information (SAI) has more information about the determination of
annuity payments. The number of units purchased is equal to the amount of the
first annuity payment divided by the new annuity unit value for the valuation
period that includes the due date of the first annuity payment. The amount of
the first annuity payment is determined in the same manner for a variable
annuity as it is for a fixed annuity. The number of annuity units stays the same
for the annuity payment period but the new annuity unit value changes to reflect
the investment income and the realized and unrealized capital gains and losses
of the Variable Account Option or Options selected, after charges made against
it. Annuity unit values assume a base rate of net investment return of 5%,
except in states which require a lower rate in which case 3.5% will be used. The
annuity unit value will rise or fall depending on whether the actual rate of net
investment return is higher or lower than the assumed base rate. In the SAI, see
"Determination of Annuity Unit Values."

    
    
   

If the age or sex of an annuitant has been misstated, any benefits will be those
that would have been purchased at the correct age and sex. Any overpayments or
underpayments made by us will be charged or credited with interest at the rate
of 6% per year. If we have made overpayments because of incorrect information
about age or sex, we'll deduct the overpayment from the next payment or payments
due. We add underpayments to the next payment.

    

<PAGE>
    
   

TIMING OF PAYMENT

    
    
   

We normally make payments from the Variable Account Options, or apply your
Adjusted Account Value to the purchase of an annuity within seven days after we
receive the required form at our Administrative Office. Our action can be
deferred, however, for any period during which

    
    
   

(1)  the New York Stock Exchange has been closed or trading on it is restricted;
    
    
   

(2)  an emergency exists so that disposal of securities isn't reasonably
     practicable or it isn't reasonably practicable for a Separate Account
     fairly to determine the value of its net assets; or

    
    
   

(3)  the SEC, by order, permits us to defer action in order to protect persons
     with interests in the Separate Account. We can defer payment of your GROs
     for up to six months, and interest will be paid on any such payment delayed
     for 30 days or more.

    
    
   

HOW YOU MAKE REQUESTS AND GIVE INSTRUCTIONS

    
    
   

When you write to our Administrative Office, use the address on the first page
of this prospectus. We can't honor your requests unless they are in proper and
complete form. Whenever possible, use one of our printed forms, which you can
get from our Administrative Office.

    
    
   

PART 6 - VOTING RIGHTS

    
    
   

VOTING RIGHTS

    
    
   

National Integrity is the legal owner of the shares of the Portfolios held by
the Separate Account and, as such, has the right to vote on certain matters.
Among other things, we may vote to elect the Portfolios' Boards of Directors, to
ratify the selection of independent auditors for the Portfolios, and on any
other matters described in the Portfolios' current prospectus or requiring a
vote by shareholders under the 1940 Act.

    
    
   

Whenever a shareholder vote is taken, we give you the opportunity to tell us how
to vote the number of shares purchased as a result of contributions to your
contract. We'll send you Portfolio proxy materials and a form for giving us
voting instructions.

    
    
   

If we don't receive instructions in time from all Owners, we'll vote shares in a
Portfolio for which no instructions have been received in the same proportion as
we vote shares for which we have received instructions. Under eligible deferred
compensation plans and certain Qualified Plans, your voting instructions must be
communicated to us indirectly, through your employer, but we aren't responsible
for any failure by your employer to ask for your instructions or to tell us what
your instructions are. We'll vote any Portfolio shares that we're entitled to
vote directly, because of amounts we have accumulated in our Separate Account,
in the same proportions that other Owners vote. If the federal securities laws
or regulations or interpretations of them change so that we are permitted to
vote shares of the Portfolios in our own right or to restrict Owner voting, we
may do so.

    
    
   

HOW WE DETERMINE YOUR VOTING SHARES
    

   

You vote only on matters concerning the Portfolios in which your contributions
have been invested. We determine the number of Portfolio shares in each Variable
Account Option under your contract by dividing the amount of your Account Value
allocated to that Option by the net asset value of one share of the
corresponding Portfolio as of the record date set by the Portfolios' Boards for
the shareholders' meeting. We count fractional shares. The record date for this
purpose can't be more than 60 days before the meeting of the shareholders'
meeting. After annuity payments have begun, voting rights are calculated in a
similar manner based on the actuarially determined value of your interest in
each Variable Account Option.
    

<PAGE>
     
   

HOW PORTFOLIO SHARES ARE VOTED

    
    
   

All Portfolio shares are entitled to one vote; fractional shares have fractional
votes. Voting is on a Portfolio-by-Portfolio basis, except for certain matters
(for example, election of Directors) that require collective approval. On
matters where the interests of the individual Portfolios differ, the approval of
the shareholders in one Portfolio isn't needed to make a decision in another
Portfolio. If shares of the Portfolios are sold to separate accounts of other
insurance companies, the shares voted by those companies in accordance with
instructions received from their contract holders will dilute the effect of
voting instructions received by National Integrity from its Owners.

    
    
   

SEPARATE ACCOUNT VOTING RIGHTS

    
    
   

Under the 1940 Act, certain actions (such as some of those described under
"Changes in How We Operate" in Part 2) may require Owner approval. In that case,
you'll be entitled to a number of votes based on the value you have in the
Variable Account Options, as described above under "How We Determine Your Voting
Shares." We'll cast votes attributable to amounts we have in the Variable
Account Options in the same proportions as votes cast by Owners.

    
    
   

PART 7 - TAX ASPECTS OF THE CONTRACTS

    
    
   

INTRODUCTION

    
    
   

The effect of federal income taxes on the amounts held under a contract, on
annuity payments, and on the economic benefits to the Owner, Annuitant, and the
beneficiary or other payee may depend on National Integrity's tax status, on the
type of retirement plan, if any, for which the contract is purchased, and upon
the tax and employment status of the individuals concerned.

    
    
   

The following discussion of the federal income tax treatment of the contract
isn't designed to cover all situations and isn't intended to be tax advice. It's
based upon our understanding of the present federal income tax laws as currently
interpreted by the Internal Revenue Service (IRS) and various courts. We can't
guarantee that the tax code or the courts will or won't change their views on
the treatment of these contracts. Future legislation may affect annuity
contracts adversely. Moreover, we haven't attempted to consider any applicable
state or other tax laws. Because of the complexity of tax laws and the fact that
tax results will vary according to the particular circumstances, any one
considering buying a contract, or selecting annuity payments under the contract,
or receiving annuity payments under a contract should consult a qualified tax
adviser. NATIONAL INTEGRITY DOESN'T MAKE ANY GUARANTEE REGARDING THE TAX STATUS,
FEDERAL, STATE, OR LOCAL, OF ANY CONTRACT OR ANY TRANSACTION INVOLVING THE
CONTRACTS.

    
    
   

TAX STATUS OF NATIONAL INTEGRITY

    
    
   

National Integrity is taxed as a life insurance company under Part I of
Subchapter L of the Internal Revenue Code of 1986, as amended (the CODE). Since
the Separate Accounts aren't separate entities from National Integrity and their
operations form a part of National Integrity, they aren't taxed separately as
"regulated investment companies" under Subchapter M of the Code. Investment
income and realized capital gains on the assets of the Separate Accounts are
reinvested and taken into account in determining the accumulation value. Under
existing federal income tax law, the Separate Accounts' investment income,
including realized net capital gains, isn't taxed to National Integrity.
National Integrity can make a tax deduction if federal tax laws change to
include these items in our taxable income.

    
    
   

YOUR CONTRACT IS AN ANNUITY

    
    
   

Under federal tax law, anyone can purchase an annuity with after-tax dollars and
your annuity earnings won't be taxed until you make a withdrawal. Or, an
individual (or employer) may buy the annuity to fund a tax-favored retirement
program (contributions are with pre-tax dollars), such as an IRA or qualified
plan. Finally, the individual (or employer) may buy the Annuity to fund a Roth
IRA (contributions are with after-tax dollars and earnings are excluded in
taxable income at distribution).

    

<PAGE>
    
   

This prospectus covers the basic tax rules that apply to an annuity purchased
directly with after-tax dollars, (NONQUALIFIED ANNUITY), and some of the special
tax rules that apply to an annuity purchased to fund a tax-favored retirement
program (QUALIFIED ANNUITY). A qualified annuity may restrict your rights and
benefits to qualify for its special treatment under the federal tax law.

    
    
   

TAXATION OF ANNUITIES GENERALLY

    
    
   

Section 72 of the Code governs the taxation of annuities. In general,
contributions you put into the annuity (your "basis" or "investment" in the
contract) won't be taxed when you receive the amounts back in a distribution.
Also, an Owner isn't taxed on the annuity's earnings until some form of
withdrawal or distribution is made under the contract. However, under certain
circumstances, the increase in value may be subject to current federal income
tax. For example, corporations, partnerships, and other non-natural persons
can't defer tax on the annuity's income unless an exception applies. In
addition, if an Owner transfers an annuity as a gift to someone other than a
spouse (or former spouse), all increases in its value are taxed at the time of
transfer. The assignment or pledge of any portion of the value of a contract
will be treated as a distribution of that portion of the value of the contract.

    
    
   

You can take withdrawals from the contract or you can wait to annuitize it when
the annuitant reaches a certain age. The tax implications are different for each
type of distribution. Section 72 of the Code says that the proceeds of a full or
partial withdrawal from a contract before annuity payments begin are treated
first as taxable income, but only to the extent of the increase of the Account
Value. The rest of the withdrawal, representing your basis in the annuity, isn't
taxable. Generally, the investment or basis in the contract equals the
contributions made by you or on your behalf, minus any amounts previously
withdrawn that weren't treated as taxable income. Special rules may apply if the
contract includes contributions made prior to August 14, 1982 that were rolled
over to the contract in a tax-free exchange.

    
    
   

If you take annuity payments over the lifetime of the annuitant, part of each
payment is considered to be a tax-free return of your investment. This tax-free
portion of each payment is figured using a ratio of the Owner's investment to
his or her expected return under the contract (exclusion Ratio). Once you get
the tax-free part, the rest of each payment will be considered the increase of
your Account Value, and is ordinary income. When all of these tax-free portions
add up to your investment in the annuity, future payments are all counted as an
increase in your Account Value, and are taxable income. If the Annuitant dies
before recovering the total investment, a deduction for the remaining basis will
generally be allowed on the Owner's final federal income tax return.

    
    
   

We may be required to withhold federal income taxes on all distributions unless
the eligible recipients elect not to have any amounts withheld and properly
notify National Integrity of that election.
    

   

The taxable portion of a distribution is treated as ordinary income and is taxed
at ordinary income tax rates. In addition, you may be subject to a tax penalty
of 10% on the taxable portion of a distribution unless it is:

    
    
   

     (1)  on or after the date on which the taxpayer attains age 59-1/2;
     (2)  as a result of the Owner's death;
     (3)  part of a series of substantially equal periodic payments (paid at
          least annually) for the life (or life expectancy) of the taxpayer or
          joint lives (or joint life expectancies) of the taxpayer and
          beneficiary;
     (4)  attributable to the taxpayer becoming disabled within the meaning of
          Code Section 72(m)(7);
     (5)  from certain qualified plans (note, however, other penalties may
          apply);
     (6)  under a qualified funding asset (as defined in Section 130(d) of the
          Code); 
     (7)  purchased by an employer on termination of certain types of qualified
          plans and held by the employer until the employee separates from
          service;
     (8)  under an immediate annuity as defined in Code Section 72(u)(4);
     (9)  purchase of a first home (distribution up to $10,000);
     (10) for certain higher education expenses; or
     (11) to cover certain deductible medical expenses.

    
    
   

Please note that items (9), (10), and (11) apply to IRAs only.

    
    
   

Any withdrawal provisions of your contract will also apply. See "Withdrawals" in
Part 5.

    

<PAGE>
    
   

All annuity contracts issued by National Integrity or its affiliates to one
Annuitant during any calendar year are treated as a single contract in measuring
the taxable income that results from surrenders and withdrawals under any one of
the contracts.

    
    
   

DISTRIBUTION-AT-DEATH RULES

    
    
   

Under section 72(s) of the Code, to be treated as an annuity, a contract must
provide the following distribution rules: (a) if any Owner dies on or after the
Retirement Date and before the entire interest in the contract has been
distributed, then the rest of that annuity must be distributed at least as
quickly as the method in effect when the owner died; and (b) if any Owner dies
before the Retirement Date, the entire interest in the contract must be
distributed within five years. However, any interest that is payable to a death
beneficiary may be annuitized over the life of that beneficiary or over a period
not extending beyond the life expectancy of that beneficiary, so long as
distributions begin within one year after the Owner's death. If the beneficiary
is the Owner's spouse, the contract (along with the deferred tax status) may be
continued in the spouse's name as the Owner.

    
    
   

DIVERSIFICATION STANDARDS

    
    
   

National Integrity manages the investments in the annuities under Section 817(h)
of the Code to ensure that will be taxed as described above.

    
    
   

TAX-FAVORED RETIREMENT PROGRAMS

    
    
   

An owner can use this annuity with certain types of retirement plans that
receive favorable treatment under the Code. Numerous tax rules apply to the
participants in qualified plans and to the contracts used in connection with
those qualified plans. These tax rules vary according to the type of plan and
the terms and conditions of the plan itself. Owners, Annuitants, and
beneficiaries are cautioned that the rights of any person to any benefits under
qualified plans may be subject to the terms and conditions of the plans
themselves, regardless of the terms and conditions of the contract. In addition,
loans from qualified contracts, where allowed, are subject to a variety of
limitations, including restrictions as to the amount that may be borrowed, the
duration of the loan, and the manner in which the loans must be repaid. (Owners
should always consult their tax advisors and retirement plan fiduciaries before
taking any loans from the plan.) Special rules also apply to the time at which
distributions must begin and the form in which the distributions must be paid.
THE STATEMENT OF ADDITIONAL INFORMATION CONTAINS GENERAL INFORMATION ABOUT THE
USE OF CONTRACTS WITH THE VARIOUS TYPES OF QUALIFIED PLANS.

    
    
   

FEDERAL AND STATE INCOME TAX WITHHOLDING

    
    
   

Certain states have indicated that pension and annuity withholding will apply to
payments made to residents. Generally, an election out of federal withholding
will also be considered an election out of state withholding. For more
information concerning a particular state, call our Administrative Office at the
toll-free number.

    
    
   

IMPACT OF TAXES TO NATIONAL INTEGRITY

    
    
   

The contracts allow National Integrity to charge the Separate Account for taxes.
National Integrity can also set up reserves for taxes.

    
    
   

TRANSFERS AMONG INVESTMENT OPTIONS

    
    
   

There won't be any tax liability if you transfer any part of the Account Value
among the Investment Options of your contract.

PART 8 - ADDITIONAL INFORMATION

    
    
   

SYSTEMATIC WITHDRAWALS

    
    
   

We offer a program that allows you to pre-authorize periodic withdrawals from
your contract prior to your Retirement Date. You can choose to have withdrawals
made monthly, quarterly, semi-annually or annually and can specify the day of
the month (other than the 29th, 30th or 31st) on which the withdrawal is to be
made. You may specify a dollar amount for each withdrawal or an annual
percentage to be withdrawn. The minimum systematic withdrawal currently is $100.
You may also specify an account for direct deposit of your systematic
withdrawals. To enroll in our systematic withdrawal program, send the
appropriate form to our Administrative Office. Withdrawals may begin one
business day after we receive the form. You may terminate your participation in
the program upon one day's prior written notice, and we may terminate or change
the systematic withdrawal program at any time. If on any withdrawal date you
don't have enough money in your Account to make all of the withdrawals you have
specified, no withdrawal will be made and your enrollment in the program will be
ended.

    
    
   

Amounts you withdraw under the systematic withdrawal program may be within the
free withdrawal amount. If so, we won't deduct a contingent withdrawal charge
and no Market Value Adjustment will be made. See "Contingent Withdrawal Charge"
in Part 4. AMOUNTS WITHDRAWN UNDER THE SYSTEMATIC WITHDRAWAL PROGRAM IN EXCESS
OF THE FREE WITHDRAWAL AMOUNT WILL BE SUBJECT TO A CONTINGENT WITHDRAWAL CHARGE
AND A MARKET VALUE ADJUSTMENT IF APPLICABLE. WITHDRAWALS ALSO MAY BE SUBJECT TO
THE 10% FEDERAL TAX PENALTY FOR EARLY WITHDRAWALS UNDER THE CONTRACTS AND TO
INCOME TAXATION. See Part 7, "Tax Aspects of the Contracts."

    
    
   

INCOME PLUS WITHDRAWAL PROGRAM

    
    
   

We offer an Income Plus Withdrawal Program that allows you to pre-authorize
substantially equal periodic withdrawals, based on your life expectancy, from
your contract prior to your reaching age 59-1/2. You won't have to pay any tax
penalty for these withdrawals, but they will be subject to ordinary income tax.
See "Taxation of Annuities Generally," in Part 7. Once you begin receiving
distributions, they shouldn't be changed or stopped until the later of:

    
    
   

o        the date you reach age 59-1/2;  or
o        five years from the date of the first distribution.

    
    
   

If you change or stop the distribution or take an additional withdrawal, you may
have to pay a 10% penalty tax that would have been due on all prior
distributions before you reached age 59-1/2 made under the Income Plus Program
and for any interest.

    

    
   

You can choose the Income Plus Withdrawal Program any time before you reach age
59-1/2. You can elect this option by sending the election form to our
Administrative Office. You may choose to have withdrawals made monthly,
quarterly, semi-annually or annually and may specify the day of the month (other
than the 29th, 30th or 31st) on which the withdrawal is to be made. We'll
calculate the amount of the distribution under a method you select, subject to a
minimum, which is currently $100. You must also specify an account for direct
deposit of your Income Plus Withdrawals.

    
    
   

To enroll in our Income Plus Withdrawal Program, send the appropriate form to
our Administrative Office. Your withdrawals may begin at least one Business Day
after we receive your form. You may end your participation in the program upon
seven Business Day's prior written notice, and we may terminate or change the
Income Plus Program at any time. If on any withdrawal date you don't have enough
money to make all of the withdrawals you have specified, no withdrawal will be
made and your enrollment in the program will be ended. This program isn't
available in connection with the Systematic Withdrawal Program, Dollar Cost
Averaging, or Asset Allocation and Rebalancing Program.

    
    
   

If you haven't used up your free withdrawals in any given contract year, amounts
you withdraw under the Income Plus Withdrawal Program may be within the free
withdrawal amount. If they are, no contingent withdrawal charge or Market Value
Adjustment will be made. See "Contingent Withdrawal Charge" in Part 4. AMOUNTS
WITHDRAWN UNDER THE INCOME PLUS WITHDRAWAL PROGRAM IN EXCESS OF THE FREE
WITHDRAWAL AMOUNT WILL BE SUBJECT TO A CONTINGENT WITHDRAWAL CHARGE AND A MARKET
VALUE ADJUSTMENT IF APPLICABLE.

    

<PAGE>
    
   

DOLLAR COST AVERAGING

    
    
   

We offer a dollar cost averaging program under which we transfer contributions
that you have made to the VIP Money Market Option on a monthly, quarterly,
semi-annual or annual basis to one or more other Variable Account Options. You
must tell us how much you want to be transferred into each Variable Account
Option. The current minimum transfer to each Option is $250. We won't charge a
transfer charge under our dollar cost averaging program, and these transfers
won't count towards your twelve free transfers.

    
    
   

To enroll in our dollar cost averaging program, send the appropriate form to our
Administrative Office. You may terminate your participation in the program upon
one day's prior written notice, and we may terminate or change the dollar cost
averaging program at any time. If you don't have enough money in the VIP Money
Market Option to transfer to each Variable Account Option specified, no transfer
will be made and your enrollment in the program will be ended.

    
    
   

CUSTOMIZED ASSET REBALANCING

    
    
   

We offer a Customized Asset Rebalancing program that allows you to determine how
often rebalancing occurs. You can choose to rebalance monthly, quarterly,
semi-annually or annually. The value in the Variable Account Options will be
automatically rebalanced by transfers among the Variable Account Options, and
you will receive a confirmation notice after each rebalancing. Transfers will
occur only to and from those Variable Account Options where you have current
contribution allocations. We won't charge a transfer charge for transfers under
our Customized Asset Rebalancing program, and these transfers won't count
towards your twelve free transfers.

    
    
   

GROs aren't eligible for the Customized Asset Rebalancing program.

    
    
   

To enroll in our Customized Asset Rebalancing program, send the appropriate form
to our Administrative Office. You should be aware that other allocation
programs, such as dollar cost averaging, as well as transfers and withdrawals
that you make, may not work with the Customized Asset Rebalancing program. You
should, therefore, monitor your use of other programs, transfers, and
withdrawals while the Customized Asset Rebalancing program is in effect. You may
terminate your participation in the program upon one day's prior written notice,
and we may terminate or change the Customized Asset Rebalancing program at any
time.

    
    
   

ASSET ALLOCATION AND REBALANCING PROGRAM

    
    
   

We offer an Asset Allocation and Rebalancing Program developed in consultation
with Callan Associates. Callan Associates is an independent research and 
consulting firm, specializing in the strategic asset allocation decision.

    

   

You may select one of five proposed Asset Allocation Rebalancing Models:
Conservative, Moderately Conservative, Moderate, Moderately Aggressive, or
Aggressive. The contributions you are making will initially be allocated among
the Options established for each Model. If we change the Model, your account
values will be automatically reallocated accordingly unless you have terminated
your participation. You and your financial representative also have the option
to design a program that is tailored to your specific retirement needs.

    
    
   

When you select this program, your account values will be allocated and your
variable portfolios will be rebalanced automatically at least annually. The
program automatically applies to all contributions made to your annuity contract
while you are still participating. You will receive a confirmation notice after
each rebalancing. We won't charge a transfer charge for transfers made under the
Asset Allocation and Rebalancing Program. These transfers won't count toward
your twelve free transfers.

    
    
   

In each Asset Allocation Rebalancing Model, a part of all contributions is
allocated to a five-year Guaranteed Rate Option (GRO). The amount allocated to
the GRO won't be reallocated or rebalanced while you are participating in a
specific Model. You may cancel or change the Model you have selected at any
time. If you withdraw or transfer your GRO funds, they may be subject to a
Market Value Adjustment that may increase or decrease your account value.

    
    
   

To enroll in the Asset Allocation and Rebalancing Program, complete the
appropriate form and send it to our Administrative office. You should be aware
that other allocation programs, such as dollar cost averaging, transfers and
withdrawals that you make, may not work with the Customized Asset Rebalancing
program. If, after selecting 

    

<PAGE>
    
   

one of the five models, you request a transaction that results in a reallocation
outside one of the Models, your participation in the Model program automatically
ends. You should, therefore, monitor your use of other programs, transfers, and
withdrawals while the Customized Asset Rebalancing program is in effect. This
program isn't available with the Customized Asset Rebalancing program. We can
terminate or change this program in whole or in part, or restrict contributions
to the program. This program may not be available in all states.

    
    
   

You may terminate participation in this program upon one day's prior written
notice.

    
    
   

SYSTEMATIC CONTRIBUTIONS

    
    
   

We offer a program for systematic contributions that allows you to pre-authorize
monthly withdrawals from your checking account for payment to us. To enroll in
this program, send the appropriate form to our Administrative Office. You may
terminate your participation in the program upon 30 days' prior written notice.
We may terminate your participation if your bank declines to make any payment.
The minimum amount for systematic contributions is $100 per month.

    
    
   

PERFORMANCE INFORMATION

    
    
   

Performance data for the Variable Account Options, including the yield and
effective yield of the VIP Money Market Option, the yield of the other Options,
and the total return of all of the Options may appear in advertisements or sales
literature. This performance data is based only the performance of a
hypothetical investment in that Option during the particular time period on
which the calculations are based. Performance information should be considered
in light of the investment objectives and policies of the Portfolio in which the
Option invests and the market conditions during the given time frame. It
shouldn't be considered as a representation of performance to be achieved in the
future.

    
    
   

TOTAL RETURNS are based on the overall dollar or percentage change in value of a
hypothetical investment in an Option. Total return information reflects changes
in Portfolio share price, the automatic reinvestment of all distributions and
the deduction of contract charges and expenses that may apply, including any
contingent withdrawal charge that would apply if an Owner surrendered the
contract at the end of the period shown. Total returns also may be shown that
don't take into account the contingent withdrawal charge or the annual
administrative charge that is applied when the Account Value is less than
$50,000 at the end of the contract year.

    
    
   

CUMULATIVE TOTAL RETURNS show an Investment Option's performance over a specific
period of time, usually seven years. An AVERAGE ANNUAL TOTAL RETURN shows the
hypothetical yearly return that would have produced the same cumulative total
return if the Investment Option experienced exactly the same return each year
for the entire period shown. Because performance will fluctuate on a
year-by-year basis, the average annual total returns tend to show a smooth
result that won't mirror actual performance, even though the end result will be
the same.

    
    
   

Some Investment Options may also advertise YIELD, which shows the income
generated by an investment in that particular Option over a specified period of
time. This income is annualized and shown as a percentage. Yields don't take
into account capital gains or losses or the contingent withdrawal charge that
may apply if you withdraw your money at the end of the hypothetical period.

    
    
   

The VIP Money Market Option may advertise its CURRENT and EFFECTIVE YIELD.
Current yield reflects the income generated by an investment in that Option over
a specified seven-day period. Effective yield is calculated in a similar manner
except that it assumes that the income earned is reinvested, and the income on
the reinvested amount is included. The VIP II Investment Grade Bond and VIP High
Income Option may advertise a 30-day yield which reflects the income generated
by an investment in that Option over a specified 30-day period.

    
    
   

For a detailed description of the methods used to determine yield and total
return for the Variable Account Options, see the Statement of Additional
Information.

    
    
   

PART 9 - PRIOR CONTRACTS

    
    
   

DEATH BENEFIT INFORMATION FOR CONTRACTS ISSUED BEFORE JANUARY 1, 1997

    
    
   

This section shows the Death Benefit information for contracts issued before
January 1, 1997. It may be different 

    

<PAGE>
    
   

from other provisions in this prospectus. For contracts issued before 1997, the
following provisions apply:

    
    
   

For contracts issued before January 1, 1995, the amount of the death benefit is
the greatest of:

    
    
   

     -    your Adjusted Account Value

     -    the Account Value at the beginning of the seventh contract year, plus
          subsequent contributions and minus subsequent withdrawals C your total
          contributions less the sum of withdrawals

     -    for Annuitants younger than 70 years old on the birthday nearest the
          date on which their contract was issued, an enhanced minimum death
          benefit, explained below.

    
    
   

For contracts issued during 1995, the amount of the death benefit is the
greatest of:

    
    
   

          C    your Adjusted Account Value
          C    the highest Account Value at the beginning of any contract year,
               plus subsequent contributions and minus subsequent withdrawals
          C    your total contributions less the sum of withdrawals

    
    
   

For contracts issued during 1996, the amount of the death benefit is the
greatest of:

          C    your Account Value
          C    the highest Account Value at the beginning of any contract year,
               plus subsequent contributions and minus subsequent withdrawals
          C    your total contributions less the sum of withdrawals

    
    

   

"Subsequent withdrawals" for purposes of calculation of a death benefit reflect
any market value adjustments that apply to those withdrawals and reduce the
death benefit on a pro rata basis.

    
    
   

The enhanced minimum death benefit is the same as the guaranteed death benefit,
except that the guaranteed death benefit may not exceed the maximum guaranteed
death benefit. The guaranteed death benefit on your Participation Date is your
initial contribution. After that, every month we recalculate that portion of
your guaranteed death benefit allocated to the Separate Account by adding
interest at an annual rate of 7% until the contract anniversary nearest your
70th birthday, subject to the maximum. We subtract from that the sum of any
withdrawals or transfers from the Separate Account during the month and a pro
rata amount of the interest accumulated that applies to the withdrawn or
transferred amount. Therefore, your guaranteed death benefit at any time,
subject to the maximum, is the sum of (1) your Guarantee Period Values, and (2)
your Separate Account contributions, including the amount of interest calculated
on your Separate Account values for purposes of determining the guaranteed death
benefit, less any withdrawals or transfers and less the interest calculated on a
pro rata basis on those withdrawals or transfers. Your maximum guaranteed death
benefit is determined by totaling your contributions during your first five
participation years, subtracting all withdrawals, taking into consideration any
market value adjustments made under the contract, multiplying the result by two,
and then adding that to your total contributions made after the first five
participation years.

    
    
   

REDUCTION IN CHARGES

    
    
   

If your contract was issued on or after January 1, 1995, but before January 1,
1997, the effective annual rate of mortality, expense and administrative charges
will reduce to 1.10% after your contract has been in effect for six years.

    
    
   

CONTINGENT WITHDRAWAL CHARGE

    
    
   

For contracts issued before February 15, 1997 (2/27/97 in Washington, 5/30/97 in
Pennsylvania, 7/7/97 in Maryland, 10/16/97 in Oregon) the following rules apply
even if they are different from other provisions in this prospectus:

    
    
   

There is a withdrawal charge of up to 7% on all contributions withdrawn. As
shown below, this charge varies, depending upon the "age" of the contributions
included in the withdrawal, that is, how long ago you made your contributions.
The maximum percentage of 7% would apply if the entire amount of the withdrawal
consisted of contributions made during your current contract year. No withdrawal
charge applies when you withdraw contributions 

    

<PAGE>
    
   

made earlier than your fifth prior contribution year. For purposes of
calculating the withdrawal charge, (1) the oldest contributions will be treated
as the first withdrawn and more recent contributions next, and (2) partial
withdrawals up to the free withdrawal amount won't be considered a withdrawal of
any contributions. For partial withdrawals, the total amount deducted from your
Account Value will include the withdrawal amount requested, any applicable
Market Value Adjustment and any applicable withdrawal charge, so that the net
amount you receive will be the amount requested.

    
    
   

No charge will be applied to your partial withdrawals that don't exceed the free
withdrawal amount in any contract year. On any Business Day, the free withdrawal
amount is the greater of (i) 10% of your Account Value and (ii) any investment
gain during the prior contract year, less withdrawals during the current
contract year. Investment gain is calculated as the increase in the Account
Value during the prior contract year, minus contributions during that year, plus
withdrawals made during that year. We'll deduct contingent withdrawal charges
for any partial withdrawal amount that is over the free withdrawal amount. The
contingent withdrawal charge is a sales charge to help pay our costs of selling
and promoting the contracts. We don't expect revenues from contingent withdrawal
charges to cover all of those costs. Any shortfall will be made up from our
General Account assets, which may include profits from other charges under the
contracts.

  We won't deduct a contingent withdrawal charge if the Annuitant uses the
  withdrawal to buy from Integrity either an immediate annuity benefit with life
  contingencies or an immediate annuity without life contingencies with a
  restricted prepayment option that provides for level payments over five or
  more years. Similarly, we won't deduct a charge if the Annuitant dies and the
  withdrawal is made by the Annuitant's beneficiary. See "Death Benefits and
  Similar Benefit Distributions" in Part 5.

    
    
   

  Withdrawals will be taken from your Accounts in the same proportions as you
  contributed it to them. For example if your contributions are divided in equal
  25% shares among four Investment Options, when you make a withdrawal, 25% of
  the money withdrawn will come from each of your Investment Options. You can
  tell us if you want your withdrawal handled differently. The minimum
  withdrawal permitted is $300.

    
    
   

RETIREMENT DATE

    
    
   

For Contracts issued before January 1, 1997, the Retirement Date will be the
date you specify, but no later than your 85th birthday or the 10th Contract
Anniversary, whichever is later.

ILLUSTRATION OF A MARKET VALUE ADJUSTMENT

    
    
   

<TABLE>

                         <S>                                <C>       
                         Contribution:                      $50,000.00

                         GRO Account duration:     7 Years

                         Guaranteed Interest Rate: 5% Annual Effective Rate
</TABLE>

    
    
   

The following examples illustrate how the Market Value Adjustment and the
contingent withdrawal charge may affect the values of a contract upon a
withdrawal. The 5% assumed Guaranteed Interest Rate is the same rate used in the
Example under "Table of Annual Fees and Expenses" in this Prospectus. In these
examples, the withdrawal occurs three years after the initial contribution. The
Market Value Adjustment operates in a similar manner for transfers. No
contingent withdrawal charge applies to transfers.

    
    
   

The GRO Value for this $50,000 contribution is $70,355.02 at the expiration of
the GRO Account. After three years, the GRO Value is $57,881.25. It is also
assumed, for the purposes of these examples, that no prior partial withdrawals
or transfers have occurred.

    
    
   

The Market Value Adjustment will be based on the rate we are then crediting (at
the time of the withdrawal) on new contributions to GRO Accounts of the same
duration as the time remaining in your GRO Account, rounded to the next higher
number of complete months. If we don't declare a rate for the exact time
remaining, we will interpolate between the Guaranteed Interest Rates for GRO
Accounts of durations closest to (next higher and next lower) the remaining
period described above. Three years after the initial contribution, there would
have been four years remaining in your GRO Account. These examples also show the
withdrawal charge that would be calculated separately.

    
    
   

EXAMPLE OF A DOWNWARD MARKET VALUE ADJUSTMENT:

    
    
   

A downward Market Value Adjustment results from a full or partial withdrawal
that occurs when interest rates have increased. Assume interest rates have
increased three years after the initial contribution and we are then crediting
6.25% for a four-year GRO Account. Upon a full withdrawal, the Market Value
Adjustment, applying the above formula would be:

    
    
   
        -0.0551589 = [(1 + .05)48/12 / (1 + .0625 + .0025)48/12] - 1
    
    
   

The Market Value Adjustment is a reduction of $3,192.67 from the GRO Value:

    
    
   

        -$3,192.67 = -0.0551589 X $57,881.25

    
    
   

The Market Adjusted Value would be:

    
    
   

        $54,688.58 = $57,881.25 - $3,192.67

    
    
   

A withdrawal charge of 5% would be assessed against the $50,000 original
contribution:

    
    
   

        $2,500.00 = $50,000.00 X .05

    
    
   

Thus, the amount payable on a full withdrawal would be:

    
    
   

        $52,188.58 = $57,881.25 - $3,192.67 - $2,500.00

    
    
   

If instead of a full withdrawal, $20,000 was requested, we would first determine
the free withdrawal amount:

    
    
   

        $5,788.13 = $57,881.25 X .10

    

    
   

The non-free amount would be:

    

<PAGE>    

   

        $14,211.87 = $20,000.00 - $5,788.13

    
    
   

The Market Value Adjustment, which is only applicable to the non-free amount,
would be

    
    
   

        - $783.91 = -0.0551589 X $14,211.87

    
    
   

The withdrawal charge would be:

    
    
   

        $789.25 = [($14,211.87+ $783.91)/(1 - .05)] - ($14,211.87+ 783.91)

    
    
   

Thus, the total amount needed to provide $20,000 after the Market Value
Adjustment and withdrawal charge would be:

    
    
   

        $21,573.16 = $20,000.00 + $783.91 + $789.25

    
    
   

The ending Account Value would be:

    
    
   

        $36,308.09 = $57,881.25 - $21,573.16

    
    
   

EXAMPLE OF AN UPWARD MARKET VALUE ADJUSTMENT:

    
    
   

An upward Market Value Adjustment results from a full or partial withdrawal that
occurs when interest rates have decreased. Assume interest rates have decreased
three years after the initial contribution and we are then crediting 4% for a
four-year GRO Account. Upon a full withdrawal, the Market Value Adjustment,
applying the formula set forth in the prospectus, would be:

    
    
   

        .0290890 = [(1 + .05)48/12 / (1 + .04 + .0025)48/12] - 1

    
    
   

The Market Value Adjustment is an increase of $1,683.71 to the GRO Value:

    
    
   

        $1,683.71 = .0290890 X $57,881.25

    
    
   

The Market Adjusted Value would be:

    
    
   

        $59,564.96 = $57,881.25 + $1,683.71

    
    
   

A withdrawal charge of 5% would be assessed against the $50,000 original
contribution:

    
    
   

        $2,500.00 = $50,000.00 X .05

    
    
   

Thus, the amount payable on a full withdrawal would be:

    
    
   

        $57,064.96 = $57,881.25 + $1,683.71 - $2,500.00

    
    
   

If instead of a full withdrawal, $20,000 was requested, the free withdrawal
amount and non-free amount would first be determined as above:

    
    
   

                Free Amount =    $ 5,788.13

    
    
   

         Non-Free Amount =    $14,211.87

    
    
   

The Market Value Adjustment would be:

    
    
   

        $413.41 = .0290890 X $14,211.87

    
    
   

The withdrawal charge would be:

    

<PAGE>

   

        $726.23 = [($14,211.87 - $413.41)/(1 - .05)] - ($14,211.87 - $413.41)

    
    
   

Thus, the total amount needed to provide $20,000 after the Market Value
Adjustment and withdrawal charge would be:

    
    
   

        $20,312.82 = $20,000.00 - $413.41 + $726.23

    
    
   

The ending Account Value would be:

    
    
   

        $37,568.43 = $57,881.25 - $20,312.82

    
    
   

Actual Market Value Adjustments may have more or less impact than shown in the
examples, depending on the actual change in interest crediting rate and the
timing of the withdrawal or transfer in relation to the time remaining in the
GRO Account. Also, the Market Value Adjustment can never decrease the Account
Value below premium plus 3% interest, before any applicable charges. Account
values less than $50,000 will be subject to a $30 annual charge.

PART 1 - NATIONAL INTEGRITY AND CUSTODIAN

    

   

National Integrity Life Insurance Company is a New York stock life insurance
company that sells life insurance and annuities. Its principal executive offices
are located at 15 Matthews Street, Suite 200, Goshen, NY 10924. National
Integrity, the depositor of Separate Account I, is a wholly owned subsidiary of
Integrity Life Insurance Company, an Ohio corporation. All outstanding shares of
Integrity Life Insurance Company are owned by ARM Financial Group, Inc. (ARM), a
Delaware corporation that's a financial services company focusing on the
long-term savings and retirement marketplace by providing retail and
institutional products and services throughout the United States. ARM owns 100%
of the stock of (i) ARM Securities Corporation (ARM SECURITIES), a Minnesota
corporation, registered with the SEC as a broker-dealer and a member of the
National Association of Securities Dealers, Inc., (ii) Integrity Capital
Advisors, Inc., a Delaware corporation registered with the SEC as an investment
adviser, (iii) SBM Certificate Company, a Minnesota corporation registered with
the SEC as an issuer of face-amount certificates, and (iv) ARM Transfer Agency,
Inc., a Delaware corporation registered with the SEC as a transfer and dividend
disbursing agency

    

   

ARM is 100% publicly owned, trading on the New York Stock Exchange (NYSE). No
one has the direct or indirect power to control ARM, except power he or she may
have by virtue of his or her capacity as a director or executive officer of ARM;
no individual beneficially owns more than 5% of the common shares.

    

   

Since 1994, ARM has provided substantially all of the services required to be
performed on behalf of the Separate Account. Total fees paid to ARM by National
Integrity for management services in 1997 were $5,855,216 and in 1998 were
$8,766,003 including services applicable to the Registrant.

    

   

National Integrity is the custodian for the shares of the Funds owned by the
Separate Account. The Funds' shares are held in book-entry form.

    

   

Reports and marketing materials, from time to time, may include information
concerning the rating of National Integrity, as determined by A.M. Best Company,
Moody's Investor Service, Standard & Poor's Corporation, Duff & Phelps
Corporation, or other recognized rating services. National Integrity is
currently rated "A" (Excellent) by A.M. Best Company, and has received claims
paying ability ratings of 

    

<PAGE>

   

"A" (Good) from Standard & Poor's Corporation, "Baa1"
from Moody's Investors Service, Inc., and "A+" (High) from Duff and Phelps
Credit Rating Company. However, National Integrity doesn't guarantee the
investment performance of the portfolios, and these ratings don't reflect
protection against investment risk.

    

PART 2 - DISTRIBUTION OF THE CONTRACTS

   

ARM Securities, a wholly owned subsidiary of ARM, is the principal underwriter
of the contracts. ARM Securities is registered with the SEC as a broker-dealer
and is a member in good standing of the National Association of Securities
Dealers, Inc. ARM Securities' address is 515 West Market Street, Louisville,
Kentucky 40202. The contracts are offered through ARM Securities on a continuous
basis.

    

   

We generally pay a maximum distribution allowance of 7.5% of initial
contribution and 7% of additional contributions, plus .50% trail commission paid
on Account Value after the 8th Contract Year. The amount of distribution
allowances paid was $1,753,582 for the year ended December 31, 1998, $2,647,756
for the year ended December 31, 1997 and $2,229,269 for the year ended December
31, 1996. Distribution allowances weren't retained by ARM Securities during
these years. National Integrity may from time to time pay or allow additional
promotional incentives, in the form of cash or other compensation, to
broker-dealers that sell contracts. In some instances, those types of incentives
may be offered only to certain broker-dealers that sell or are expected to sell
certain minimum amounts of the contracts during specified time periods.

    

PART 3 - PERFORMANCE INFORMATION

   

Each Variable Account Option may from time to time include the Average Annual
Total Return, the Cumulative Total Return, and Yield of its shares in
advertisements or in information furnished to shareholders. The VIP Money Market
Option may also from time to time include the Yield and Effective Yield of its
shares in information furnished to shareholders. Performance information is
computed separately for each Option in accordance with the formulas described
below. At any time in the future, total return and yields may be higher or lower
than in the past and we can't guarantee that any historical results will
continue.

    

TOTAL RETURNS

   

Total returns reflect all aspects of an Option's return, including the automatic
reinvestment by the Option of all distributions and the deduction of all charges
that apply to the Option on an annual basis, including mortality risk and
expense charges, the annual administrative charge and other charges against
contract values. For purposes of charges not based upon a percentage of contract
values, an average account value of $40,000 has been used. Quotations also will
assume a termination (surrender) at the end of the particular period and reflect
the deductions of the contingent withdrawal charge, if they would apply. Any
total return calculation will be based upon the assumption that the Option
corresponding to the investment portfolio was in existence throughout the stated
period and that the applicable contractual charges and expenses of the Option
during the stated period were equal to those that currently apply under the
contract. Total returns may be shown at the same time that do not take into
account deduction of the contingent withdrawal charge, and/or the annual
administrative charge.

    


<PAGE>

   

AVERAGE ANNUAL TOTAL RETURNS are calculated by determining the growth or decline
in value of a hypothetical historical investment in the Option over certain
periods, including 1, 3, 5, and 10 years (up to the life of the Option), and
then calculating the annually compounded percentage rate that would have
produced the same result if the rate of growth or decline in value had been
constant over the period. Investors should realize that the Option's performance
is not constant over time, but changes from year to year, and that the average
annual returns represent the averages of historical figures as opposed to the
actual historical performance of an Option during any portion of the period
shown. Average annual returns are calculated pursuant to the following formula:
P(1+T)(n) = ERV, where P is a hypothetical initial payment of $1,000, T is the
average annual total return, n is the number of years, and ERV is the withdrawal
value at the end of the period.

    

CUMULATIVE TOTAL RETURNS are UNAVERAGED and reflect the simple percentage change
in the value of a hypothetical investment in the Option over a stated period of
time. In addition to the period since inception, cumulative total returns may be
calculated on a year-to-date basis at the end of each calendar month in the
current calendar year. The last day of the period for year-to-date returns is
the last day of the most recent calendar month at the time of publication.

YIELDS

   

Some Options may advertise yields. Yields quoted in advertising reflect the
change in value of a hypothetical investment in the Option over a stated period
of time, not taking into account capital gains or losses or any contingent
withdrawal charge. Yields are annualized and stated as a percentage.

    

   

CURRENT YIELD and EFFECTIVE YIELD are calculated for the VIP Money Market
Option. Current Yield is based on the change in the value of a hypothetical
investment (exclusive of capital changes) over a particular 7-day period, less a
hypothetical charge reflecting deductions from contract values during the period
(the BASE PERIOD), and stated as a percentage of the investment at the start of
the base period (the BASE period return). The base period return is then
annualized by multiplying by 365/7, with the resulting yield figure carried to
at least the nearest hundredth of one percent. Effective yield assumes that all
dividends received during an annual period have been reinvested. This
compounding effect causes effective yield to be higher than current yield.
Calculation of effective yield begins with the same base period return used in
the calculation of current yield, which is then annualized to reflect weekly
compounding pursuant to the following formula: Effective Yield = {(Base Period
Return) + 1)(365/7)} - 1

(1)  Standard average annual return reflects past fund performance based on a
     $1,000 hypothetical investment period over the indicated. The performance
     figures reflect the deduction of mortality and expenses and administrative
     charges totaling 1.35%. They also reflect any withdrawal charges that would
     apply if an owner terminated the policy at the end of the period, but
     exclude deductions for the applicable premium tax charges. Surrender
     charges are 8% in year one,

    

<PAGE>

   

     declining 1% annually in years one through seven, 0% thereafter.

    

   

(2)  Inception date of the variable account option represents first trade date.
     Returns for accounts in operation for less than one year are not
     annualized.

    

   

(3)  Non-standard returns reflect all historical investment results, less
     mortality and expense and administrative charges totaling 1.35%. The
     calculation assumes the policy is still in force and therefore does not
     take withdrawal charges into consideration.

    

   

(4) Italicized returns are calculated from the inception date through year-end.

    

   

(5)  Represents the inception date of the underlying funds. Performance data for
     periods prior to the actual inception of the variable account options is
     hypothetical and based on the performance of the underlying funds. This
     performance data has been adjusted to include all insurance company
     contract charges and management fees of the underlying funds.

PERFORMANCE COMPARISONS

    

Performance information for an Option may be compared, in reports and
advertising, to: (1) Standard & Poor's Stock Index (S&P 500), Dow Jones
Industrial Averages, (DJIA), Donoghue Money Market Institutional Averages, or
other unmanaged indices generally regarded as representative of the securities
markets; (2) other variable annuity separate accounts or other investment
products tracked by Lipper Analytical Services, Inc. or the Variable Annuity
Research and Data Service, which are widely used independent research firms that
rank mutual funds and other investment companies by overall performance,
investment objectives, and assets; and (3) the Consumer Price Index (measure of
inflation) to assess the real rate of return from an investment in a contract.
Unmanaged indices may assume the reinvestment of dividends but generally do not
reflect deductions for annuity charges, investment management costs, brokerage
costs and other transaction costs that are normally paid when directly investing
in securities.

Each Option may from time to time also include the ranking of its performance
figures relative to such figures for groups of mutual funds categorized by
Lipper Analytical Services (LIPPER) as having the same or similar investment
objectives or by similar services that monitor the performance of mutual funds.
Each Option may also from time to time compare its performance to average mutual
fund performance figures compiled by Lipper in LIPPER PERFORMANCE ANALYSIS.
Advertisements or information furnished to present shareholders or prospective
investors may also include evaluations of an Option published by nationally
recognized ranking services and by financial publications that are nationally
recognized such as BARRON'S, BUSINESS WEEK, CDA TECHNOLOGIES, INC., CHANGING
TIMES, CONSUMER'S DIGEST, DOW JONES INDUSTRIAL AVERAGE, FINANCIAL PLANNING,
FINANCIAL TIMES, FINANCIAL WORLD, FORBES, FORTUNE, GLOBAL INVESTOR, HULBERT'S
FINANCIAL DIGEST, INSTITUTIONAL INVESTOR, INVESTORS DAILY, MONEY, MORNINGSTAR
MUTUAL FUNDS, THE NEW YORK TIMES, PERSONAL INVESTOR, STANGER'S INVESTMENT
ADVISER, VALUE LINE, THE WALL STREET JOURNAL, WIESENBERGER INVESTMENT COMPANY
SERVICE AND USA TODAY.

   

The performance figures described above may also be used to compare the
performance of an Option's shares against certain widely recognized standards or
indices for stock and bond market performance. The following are the indices
against which the Options may compare performance:

    

   

The Standard & Poor's Composite Index of 500 Stocks (the S&P 500) is a market

service.

   

PART 4 - DETERMINATION OF ANNUITY UNIT VALUES

    

The annuity unit value was initially fixed at $1.00 for contracts with assumed
base rates of net investment return of 5% and 3.5% a year, respectively. For
each valuation period thereafter, it is the annuity value for the preceding
valuation period multiplied by the adjusted net investment factor under the
contracts. For each valuation period, the adjusted net investment factor is
equal to the net investment factor reduced for each day in the valuation period
by:

*    .00013366 for a contract with an assumed base rate of net investment return
     of 5% a year; or

*    .00009425 for a contract with an assumed base rate of net investment return
     of 3.5% a year.

Because of this adjustment, the annuity unit value rises and falls depending on
whether the actual rate of net investment return (after charges) is higher or
lower than the assumed base rate.

All certificates have a 5% assumed base rate, except in states where that rate
is not permitted. Annuity payments under contracts with an assumed base rate of
3.5% will at first be smaller than those under contracts with a 5% assumed base
rate. Payments under the 3.5% contracts, however, will rise more rapidly when
unit values are rising, and payments will fall more slowly when unit values are
falling, than those under 5% contracts.

The amounts of variable annuity payments are determined as follows:

   

Payments normally start on the Annuitant's retirement date. The first three
monthly payments are the same and will be based on the amount taken from the
tables in the contract or on our current rates, whichever is more favorable to
the participant. Where the Company's current annuity rates are used,
contributions in the current and five prior participation years will qualify for
the Company's current individual annuity rates applicable to funds derived from
sources outside the

    


<PAGE>


   

Company. The balance of the proceeds will qualify for the Company's current
individual annuity rates for payment of proceeds.

    

The first three monthly payments depend on the assumed base rate of net
investment return and the forms of annuity chosen (and any fixed period). If the
annuity involves a life contingency, the risk class and the age of the
annuitants will affect payments.

   

Payments after the first three months will vary according to the investment
performance of the Variable Account Option or Options selected. After that, each
payment will be calculated by multiplying the number of annuity units credited
by the average annuity unit value for the second calendar month before the due
date of the payment. The number of annuity units credited equals the initial
periodic payment divided by the annuity unit value for the valuation period that
includes the due date of the first annuity payment. The average annuity unit
value is the average of the annuity unit values for the valuation periods ending
in that month. Each business day is considered a valuation period. Days that
aren't considered business days are added to the next business day and
constitute one valuation period. For example, Saturday, Sunday and Monday are
considered to be one valuation period.

    

ILLUSTRATION OF CHANGES IN ANNUITY UNIT VALUES. To show how we determine
variable annuity payments from month to month, assume that the contract value on
a retirement date is enough to fund an annuity with a monthly payment of $363
and that the annuity unit value for the valuation period that includes the due
date of the first annuity payment is $1.05. The number of annuity units credited
under your contract would be 345.71 (363 divided by 1.05 = 345.71).

If the fourth monthly payment is due in March, and the average annuity unit
value for January was $1.10, the annuity payment for March would be the number
of units (345.71) times the average annuity unit value ($1.10), or $380.28. If
the average annuity unit value was $1.00 in February, the annuity payment for
April would be 345.71 times $1.00, or $345.71.

   

For period certain life annuities and life income annuities, the participant may
not surrender or redeem once annuity payments begin. For period certain life
annuities only, if the payee (or the payee and the other annuitant under a joint
and survivor annuity) dies before the period selected ends, the remaining
payments will go to another named payee who may have the right to redeem the
annuity and get the cash value of future guaranteed payments in a lump sum. The
present value of future guaranteed payments for a period certain is based on the
number of payments left, the assumed base rate of net return, the number of
annuity units and the annuity unit value for the date the Company receives a
written request for lump sum payment of remaining values. Assets held in the
Account at least equal to all statutory reserves required for such Separate
Account.

    

   

PART 5 - TAX FAVORED RETIREMENT PROGRAMS

    

   

The contracts described in the prospectus may be used in connection with certain
tax-favored retirement programs, for groups and individuals. Following are brief
descriptions of various types of qualified plans in connection with which
National Integrity may issue a contract. National Integrity reserves the right
to change its administrative rules, such as minimum contribution amounts, as
needed to comply with the Code as to tax-favored retirement programs.

    

   

TRADITIONAL INDIVIDUAL RETIREMENT ANNUITIES

    

   

Code Section 408(b) permits eligible individuals to contribute to an individual
retirement program known as a Traditional IRA. An individual who receives
compensation and who has not reached age 70-1/2 by the end of the tax year may
establish a Traditional IRA and make contributions up to the deadline for filing
his or her federal income tax return for that year (without extensions).
Traditional IRAs are subject to limitations on the amount that may be
contributed, the persons who may be eligible, and on the time when distributions
may begin. An 

    


<PAGE>

   

individual may also rollover amounts distributed from another Traditional IRA,
Roth IRA or another tax-favored retirement program to a Traditional IRA
contract. Your Traditional IRA contract will be issued with a rider outlining
the special terms of your contract that apply to Traditional IRAs. The Owner
will be deemed to have consented to any other amendment unless the Owner
notifies us that he or she does not consent within 30 days from the date we mail
the amendment to the Owner.

    

   

ROTH INDIVIDUAL RETIREMENT ANNUITIES

    

   

Section 408(A) of the Code permits eligible individuals to contribute to an
individual retirement program known as a Roth IRA. An individual who receives
compensation may establish a Roth IRA and make contributions up to the deadline
for filing his or her federal income tax return for that year (without
extensions). Roth IRAs are subject to limitations on the amount that may be
contributed, the persons who are eligible to contribute, and on the time when a
tax-favored distribution may begin. An individual may also rollover amounts
distributed from another Roth IRA or Traditional IRA to a Roth IRA contract.
Your Roth IRA contract will be issued with a rider outlining the special terms
of your contract which apply to Roth IRAs. Any amendment made for the purpose of
complying with provisions of the Code and related regulations may be made
without the consent of the Owner. The Owner will be deemed to have consented to
any other amendment unless the Owner notifies us that he or she does not consent
within 30 days from the date we mail the amendment to the Owner.

    

   

SIMPLE INDIVIDUAL RETIREMENT ANNUITIES

    

   

Currently, we do not issue Individual Retirement Annuities known as a "SIMPLE
IRA" as defined in Section 408(p) of the Code.

    

   

TAX SHELTERED ANNUITIES

    

   

Section 403(b) of the Code permits the purchase of tax-sheltered annuities (TSA)
by public schools and certain charitable, educational and scientific
organizations described in Section 501(c)(3) of the Code. The contract is not
intended to accept other than employee contributions. Such contributions are
excluded from the gross income of the employee until the employee receives
distributions from the contract. The amount of contributions to the TSA is
limited to certain maximums imposed by Code sections 403(b), 415 and 402(g).
Furthermore, the Code sets forth additional restrictions governing such items as
transferability, distributions and withdrawals. Any employee should obtain
competent tax advice as to the tax treatment and suitability of such an
investment. Your contract will be issued with a rider outlining the special
terms that apply to a TSA.

    

   

SIMPLIFIED EMPLOYEE PENSIONS

    

   

Section 408(k) of the Code allows employers to establish simplified employee
pension plans (SEP-IRAS) for their employees, using the employees' IRAs for such
purposes, if certain criteria are met. Under these plans the employer may,
within specified limits, make deductible contributions on behalf of the
employees to IRAs. Employers intending to use the contract in connection with
such plans should seek competent advice. The SEP-IRA will be issued with a rider
outlining the special terms of the contract.

    

   

CORPORATE AND SELF-EMPLOYED (H.R. 10 AND KEOGH) PENSION AND PROFIT SHARING PLANS

    

   

Sections 401(a) and 403(a) of the Code permit corporate employers to establish
various types of tax-favored retirement plans for employees. The Self-Employed
Individuals' Tax Retirement Act of 1962, as amended, commonly referred to as
"H.R. 10" or "Keogh," permits self-employed individuals also to establish such
tax-favored retirement plans for themselves and their employees. Such retirement
plans may permit the purchase of the contract in order to provide benefits under
the plans. Employers intending to use the contract in connection with these
plans should seek competent advice. The Company can request documentation to
substantiate that a qualified plan exists and is being properly administered.
National Integrity does not administer such plans.

    

   

DEFERRED COMPENSATION PLANS OF STATE AND LOCAL GOVERNMENTS AND TAX-EXEMPT 
ORGANIZATIONS

    

   

Section 457 of the Code permits employees of state and local governments and
tax-exempt organizations to defer a portion of their compensation without paying
current taxes. The employees must be participants in an eligible deferred
compensation plan. To the extent the contracts are used in connection with an
eligible plan, employees are 

    


<PAGE>


   

considered general creditors of the employer and the employer as Owner of the
contract has the sole right to the proceeds of the contract. However, Section
457(g), as added by the Small Business and Jobs Protection Act (SBJPA) of 1996,
provides that on and after August 20, 1996, a plan maintained by an eligible
governmental employer must hold all assets and income of the plan in a trust,
custodial account, or annuity contract for the exclusive benefit of participants
and their beneficiaries. Plans in existence on August 20, 1996, should have
established a trust, custodial account, or annuity contract by January 1, 1999.
Loans to employees may be permitted under such plans; however, a Section 457
plan is not required to allow loans. Contributions to a contract in connection
with an eligible government plan are subject to limitations. Those who intend to
use the contracts in connection with such plans should seek competent advice.
The Company can request documentation to substantiate that a qualified plan
exists and is being properly administered. National Integrity does not
administer such plans.

    

<PAGE>

   

DISTRIBUTIONS UNDER TAX FAVORED RETIREMENT PROGRAMS

    

   

Distributions from tax-favored plans are subject to certain restrictions. Prior
to the enactment of the 1996 SBJPA, distributions of minimum amounts specified
by the Code must have commenced by April 1 of the calendar year following the
calendar year in which the participant reaches age 70-1/2. The SBJPA provides
participants in qualified plans, with the exception of five-percent owners and
Traditional IRA holders, to begin receiving distributions by April 1 of the
calendar year following the later of either (i) the calendar year in which the
employee reaches age 70-1/2, or (ii) the calendar year in which the employee
retires. Additional distribution rules apply after the participant's death.
Failure to make mandatory distributions may result in the imposition of a 50%
penalty tax on any difference between the required distribution amount and the
amount distributed. Distributions to a participant from all plans (other than
457 plans) in a calendar year that exceed a specific limit under the Code are
generally subject to a 15% penalty tax (in addition to any ordinary income tax)
on the excess portion of the distributions. However, the SBJPA of 1996 has
suspended the excise tax on excess distributions. The provision relating to the
excise tax on excess distributions is effective with respect to distributions
received in 1997, 1998 and 1999.

    

   

The Taxpayer Relief Act of 1997 creating Roth IRAs eliminates mandatory
distribution at age 70 1/2 for Roth IRAs.

    

   

Distributions from a tax-favored plan (not including a Traditional IRA subject
to Code Section 408(a) Roth IRA) to an employee, surviving spouse, or former
spouse who is an alternate payee under a qualified domestic relations order, in
the form of a lump sum settlement or periodic annuity payments for a fixed
period of fewer than 10 years are subject to mandatory income tax withholding of
20% of the taxable amount of the distribution, unless (1) the distributee
directs the transfer of such amounts in cash to another plan or Traditional IRA;
or (2) the payment is a minimum distribution required under the Code. The
taxable amount is the amount of the distribution less the amount allocable to
after-tax contributions. All other types of taxable distributions are subject to
withholding unless the distributee elects not to have withholding apply.

    

   

We are not permitted to make distributions from a contract unless a request has
been made. It is therefore your responsibility to comply with the minimum
distribution rules. You should consult your tax adviser regarding these rules
and their proper application.

    

   

The above description of the federal income tax consequences of the different
types of tax-favored retirement plans which may be funded by the contract is
only a brief summary and is not intended as tax advice. The rules governing the
provisions of plans are extremely complex and often difficult to comprehend.
Anything less than full compliance with all applicable rules, all of which are
subject to change, may have adverse tax consequences. A prospective Owner
considering adoption of a plan and purchase of a contract in connection
therewith should first consult a qualified and competent tax adviser, with
regard to the suitability of the contract as an investment vehicle for the plan.

PART 1 - SUMMARY

YOUR VARIABLE ANNUITY CONTRACT

In this prospectus, "we," "our" and "us" mean National Integrity Life Insurance
Company (NATIONAL INTEGRITY), a subsidiary of ARM Financial Group, Inc. (ARM).
The terms "you" and "your" mean the Annuitant, the person upon whose life the
Annuity Benefit and the Death Benefit are based, usually the Owner of the
contract. If the Annuitant doesn't own the contract, all of the rights under the
contract belong to the Owner until annuity payments begin. If a Joint Owner is
named, the Owners share the contract rights.  Contract changes or any
transactions allowed under the Contract require both Owners' signatures.  The
rules governing distribution at death apply when the first Owner dies. See
Section 7, "Distribution-at-Death Rules."

You can invest for retirement by buying a GrandMaster IV contract if you
properly complete a Customer Profile form (an application or enrollment form may
be required in some states) and make a minimum initial contribution. Because the
premium is flexible, your future contributions can be any amount you choose, as
long as it is above the minimum required contribution, discussed below.

The latest your endowment or "retirement date" can be is your 90th birthday,
unless your state law requires it to be a different date, or unless you specify
an earlier date.

YOUR BENEFITS

Your contract has an Account Value, an annuity benefit, and a death benefit.
These benefits are described in more detail below.

Your benefits under a contract may be controlled by the usual rules for taxation
of annuities, including the deferral of taxes on your investment growth until
you actually make a withdrawal. The contract also can provide your benefits
under certain tax-favored retirement programs, which may be subject to special
eligibility and contribution rules. See Part 7,  "Tax Aspects of the Contracts"
and the Statement of Additional Information for detailed information.

HOW YOUR CONTRACT IS TAXED

Under the current tax laws, any increases in the value of your contributions
won't be considered part of your taxable income until you make a withdrawal.

YOUR CONTRIBUTIONS

The minimum initial contribution is $1,000. Contributions after your first one
can be as little as $100.  Some tax-favored retirement plans allow smaller
contributions.  See  "Contributions Under Your Contract" in Part 5.

YOUR INVESTMENT OPTIONS

You may have your contributions placed in the Variable Account Options or the
GRO's, or place part of your contributions in each of them. The Variable Account
Options and the GRO's are together referred to as the INVESTMENT OPTIONS. You
may have money in as many as nine Investment Options at any one time. See
"Contributions Under Your Contract" in Part 5. To select Investment Options most
suitable for you, see Part 3, "Your Investment Options."

The Variable Account Options invest in shares of investment portfolios of mutual
funds. Each investment portfolio is referred to as a PORTFOLIO.  The investment
goal of each Variable Account Option and its corresponding Portfolio is the
same. For example, if your investment goal is to save money for retirement, you
might choose a GROWTH oriented Variable Account Option, which invests in GROWTH
Portfolios.  Your value in a Variable Account Option will vary with the
performance of the corresponding Portfolio. For a full description of the
Portfolios, see the Portfolios' prospectus and Statement of Additional
Information.


                                          5

ACCOUNT VALUE, ADJUSTED ACCOUNT VALUE AND CASH VALUE

Your ACCOUNT VALUE consists of the value of your GRO's added to the value of
your Variable Account Options. Your ADJUSTED ACCOUNT VALUE is your Account
Value, as increased or decreased (but not below the Minimum Value) by any Market
Value Adjustments. Your CASH VALUE is equal to your Adjusted Account Value,
minus any contingent withdrawal charge and minus the pro rata portion of the
annual administrative charge, if it applies. See "Charges and Fees" below.

TRANSFERS

You may transfer all or any part of your Account Value among the Investment
Options, although there are some restrictions that apply.  You can find these in
Part 5, "Transfers."  Any transfer must be for at least $250 and may be arranged
through our telephone transfer service. Transfers may also be made among certain
investment options under special services we offer to dollar cost average or
rebalance your investment in the Variable Account Options.  See Part 8, "Dollar
Cost Averaging," "Customized Asset Rebalancing" and "Asset Allocation and
Rebalancing Program.  If you make more than twelve transfers between your
Investment Options in one contract year, your account can be charged up to $20
for each transfer.

CHARGES AND FEES

If your Account Value is less than $50,000 as of the last day of any contract
year before your Retirement Date, an annual administrative expense charge of $30
is deducted from your Account.

A daily charge at an annual rate of 1.00% is deducted from the Account Value of
each of your Variable Account Options to cover mortality and expense risks
(.95%) and certain administrative expenses (.05%). The charge will never be
greater than this. For more information, see Part 4, "Deductions and Charges."

If you choose to receive the Optional Annual Stepped Up Death Benefit, an
additional daily charge at an annual rate of .25% is deducted from the Account
Value of each of your Variable Account Options.  This charge is designed to
reimburse us for increased expenses and mortality risks.

Investment advisory fees and other expenses are deducted from amounts the
Separate Account invests in the Portfolios. Fidelity Management and Research
Company receives investment management fees from the Portfolios based on the
average net assets of each Portfolio. Advisory fees can't be increased without
the consent of shareholders. See "Table of Annual Fees and Expenses" below and
"The Portfolios' Investment Adviser" in Part 3.

WITHDRAWALS

You may make any number of withdrawals from your contract as often as you wish.
Each withdrawal must be for at least $300.  You may withdraw up to 10% of your
Account Value each year with no withdrawal charges.  After the first 10%, there
will be a charge for any withdrawals you make, based upon the length of time
your money has been in your account.  See "Contingent Withdrawal Charge" in Part
4.

YOUR INITIAL RIGHT TO REVOKE

You can cancel your contract within ten days after you receive it by returning
it to our Administrative Office. We will extend the ten-day period as required
by law in some states.  If you cancel your contract, we'll return your entire
contribution, with adjustments made for any investment gain or loss experienced
by the Variable Account Option from the date you purchased it until the date we
receive your cancelled contract, including any charges deducted. If your state
requires, we'll return all of your contributions without any adjustment.  We'll
return the amount of any contribution to the Guaranteed Rate Options upon
cancellation.

RISK/RETURN SUMMARY: INVESTMENTS AND RISKS

VARIABLE ANNUITY INVESTMENT GOALS

The investment goals of the GrandMaster IV Variable Annuity are protecting your
investment, building for retirement and providing future income.  We strive to
achieve these goals through extensive portfolio diversification and superior
portfolio management.

RISKS

An investment in any of the Variable Account Options carries with it certain
risks, including the risk that the value of your investment will decline and you
could lose money.  This could happen if one of the issuers of the stocks becomes
financially impaired or if the stock market as a whole declines.  Because most
of the Variable Account Options are in common stocks, there's also the inherent
risk that holders of common stock generally are behind creditors and holders of
preferred stock for payments in the event of the bankruptcy of a stock issuer.

For a complete discussion of the risks associated with an investment in any
particular Variable Account Option, see the prospectus of the corresponding
Portfolio.

YEAR 2000

Many computer programs are written so that only the last two digits of the year
are read.  Because of this, many computer systems will read the year 2000 as
1900.  This could cause many programs to malfunction. National Integrity is
evaluating, on an ongoing basis, its computer systems and the systems of other
companies on which we rely, to determine if they'll function properly, and make
the transition from 1999 to 2000 smoothly.  These activities are designed to
ensure that there is no adverse effect on our business operations.  While we've
been working very hard to make sure that this process will be problem-free, we
can't guarantee that there won't be some Year 2000 problems experienced by our
systems and we can't make any representations or guarantees that the outside
sources on which we rely will be ready to make a smooth transition to Year 2000
with their systems.

(1)  See "Deductions and Charges - Contingent Withdrawal Charge" in Part 4.  You
     have a free withdrawal of up to 10% of the Account Value in any contract
     year.

(2)  After the first twelve transfers during a contract year, we can charge a
     transfer fee of $20 for each transfer. This charge doesn't apply to
     transfers made for dollar cost averaging, asset rebalancing, or systematic
     transfers. See "Deductions and Charges - Transfer Charge" in Part 4.

(4)  At the time you apply for a contract, you can choose to receive the
     Optional Annual Stepped Up Death Benefit in lieu of receiving the standard
     Death Benefit.  If you choose the Optional Death Benefit, we'll deduct an
     additional charge equal to an annual rate of .25% of the average account
     value.  For more information, see "Deductions and Charges - Optional Death
     Benefit Rider Charge" in Part 4 and "Death Benefits and Similar Benefit
     Distributions" in Part 5.

(5)  The  "Other Expenses" reflect the payment of 0.10% pursuant to a Rule 12b-1
     Plan adopted by the underlying Mutual Funds.

(6)  Part of the brokerage commissions that certain Portfolios pay was used to
     reduce the Portfolios' expenses.  In addition, certain Portfolios have
     arranged with their custodian to use uninvested cash balances to reduce
     custodian expenses.  Including these reductions, the total operating
     expenses presented in the table would have been .67% for VIP Equity-Income
     Portfolio, .75% for VIP Growth Portfolio, .97% for VIP Overseas Portfolio,
     .77% for VIP II Asset Manager Portfolio, .75% for VIP II Contrafund
     Portfolio, .88% for VIP II Asset Manager: Growth Portfolio, .79% for VIP
     III Growth Opportunities Portfolio, .69% for VIP III Balanced Portfolio and
     .70% for VIP III Growth and Income Portfolio.

(7)  The investment adviser agreed to reimburse part of the expenses for the VIP
     II Index 500 Portfolio and the VIP III Mid Cap Portfolio during the period.
     Without this reimbursement, the management fee, other expenses and total
     expenses would have been .28%, .11%, and .39%, respectively for the VIP II
     Index 500 Portfolio and .56%, 115.40% and 115.96% respectively for the VIP
     III Mid Cap Portfolio.

These examples take into consideration the maximum amount that could be charged
to your contract (1.25%) for the election of the Optional Death Benefit Rider
(see "Death Benefits and Similar Benefit Distributions" in Part 5 for additional
information on the charges assessed).  For those contracts under which the
Optional Death Benefit Rider has not been elected, the expenses in these
examples will be lower.

These examples assume that all of the fixed charges of the Separate Account and
of the investment advisory fees and other expenses of the Portfolios will
continue as they were for their most current fiscal year or estimated expenses
(after reimbursement), if applicable.  ACTUAL PORTFOLIO EXPENSES MAY BE MORE OR
LESS. The annual rate of return assumed in the examples isn't an estimate or
guarantee of future investment performance. The table assumes an estimated
$40,000 average contract value, so that the administrative charge per $1,000 of
net asset value in the Separate Account is $0.75. Such per $1,000 charge would
be higher for smaller Account Values and lower for higher values.

PART 2 - NATIONAL INTEGRITY AND THE SEPARATE ACCOUNT


NATIONAL INTEGRITY LIFE INSURANCE COMPANY

National Integrity is a stock life insurance company organized under the laws of
New York.  Our home office is located in Goshen, New York. We are authorized to
sell life insurance and annuities in eight states and the District of Columbia.
We sell flexible premium annuities with underlying investment options other than
the Portfolios, and fixed single premium annuities.  We also provide
administrative and investment support for products designed, underwritten and
sold by other companies.

National Integrity is a subsidiary of ARM Financial Group, Inc., which
specializes providing retail and institutional customers with products and
services designed for long-term savings and retirement planning. ARM is a
publicly traded company listed on the New York Stock Exchange under the symbol
"ARM." At December 31, 1998, ARM had $9.9 billion of assets under management.

THE SEPARATE ACCOUNT AND THE VARIABLE ACCOUNT OPTIONS

The Separate Account is established and maintained under the insurance laws of
the State of New York. It is a unit investment trust registered with the
Securities and Exchange Commission (the SEC) under the Investment Company Act of
1940 (1940 ACT). A unit investment trust is a type of investment company. SEC
registration doesn't mean that the SEC is involved in any way in supervising the
management or investment policies of the Separate Account. Each Variable Account
Option invests in shares of a corresponding Portfolio of the Portfolios. We may
establish additional Options from time to time. The Variable Account Options
currently available to you are listed in Part 3, "Your Investment Options."
Prior to September 3, 1991, the Portfolios invested in shares of corresponding
portfolios of Prism Investment Trust.

ASSETS OF OUR SEPARATE ACCOUNT

Under New York law, we own the assets of our Separate Account and use them to
support the variable portion of yours and other variable annuity contracts.
Annuitants under other variable annuity contracts participate in the Separate
Account in proportion to the amounts in their contracts. We can't use the
Separate Account's assets supporting the variable portion of these variable
contracts to satisfy liabilities arising out of any of our other businesses.
Under certain unlikely circumstances, one Variable Account Option may be liable
for claims relating to the operations of another Option.

Income, gains and losses, whether or not realized, from assets allocated to the
Separate Account are credited to or charged against the Separate Account without
regard to our other income, gains or losses. We may allow charges owed to us to
stay in the Separate Account, and in that way, we can participate
proportionately in the Separate Account. Amounts in the Separate Account in
excess of reserves and other liabilities belong to us, and we may transfer them
to our general account.

CHANGES IN HOW WE OPERATE

We can change how we or our Separate Account operate, subject to your approval
when required by the 1940 Act or other applicable law or regulation. We'll
notify you if any changes result in a material change in the underlying
investments of a Variable Account Option. WE MAY:

- -  add Options to, or remove Options from, our Separate Account, combine two or
   more Options within our Separate Account, or withdraw assets relating to your
   contract from one Option and put them into another;
- -  register or end the registration of the Separate Account under the 1940 Act;


                                          12
<PAGE>

- -  operate our Separate Account under the direction of a committee or discharge
   a committee at any time (the committee may be composed of a majority of
   persons who are "interested persons" of National Integrity under the 1940
   Act);
- -  restrict or eliminate any voting rights of Owners or others who have voting
   rights that affect our Separate Account;
- -  cause one or more Options to invest in a mutual fund other than or in
   addition to the Portfolios;
- -  operate our Separate Account or one or more of the Options in any other form
   the law allows, including a form that allows us to make direct investments.
   We may make any legal investments we wish. In choosing these investments,
   we'll rely on our own or outside counsel for advice.

THE PORTFOLIOS

Management fees and other expenses deducted from each Portfolio are described in
that Portfolio's prospectus.  FOR A PROSPECTUS CONTAINING MORE COMPLETE
INFORMATION ON ANY PORTFOLIO, CALL OUR ADMINISTRATIVE OFFICE TOLL-FREE AT
1-800-443-1778.

Each of the Portfolios is an open-end diversified management investment company
registered with the SEC.

The Portfolios serve as investment vehicles for variable annuity and variable
life contracts of insurance companies. Shares of the Portfolios currently are
available to the separate accounts of a number of insurance companies, both
affiliated and unaffiliated with Fidelity Management or Integrity. The Board of
Trustees of each of the Portfolios is responsible for monitoring the Fund for
any material irreconcilable conflict between the interests of the policyowners
of all separate accounts investing in the Portfolio and determining what action,
if any, should be taken in response. If we believe that a Portfolio's response
to any of those events doesn't adequately protect our contract owners, we'll see
to it that appropriate and available action is taken. See "The Fund and the
Fidelity Organization" in the Portfolios' prospectus for a further discussion of
the risks associated with the offering of shares to our Separate Account and the
separate accounts of other insurance companies.

THE PORTFOLIOS' INVESTMENT ADVISER. Fidelity Management & Research Company
(FIDELITY MANAGEMENT) is a registered investment adviser under the Investment
Advisers Act of 1940.  It serves as the investment adviser to each Portfolio.
Bankers Trust Company ("BT") is the VIP II Index 500 Portfolios' sub-adviser.
BT, a New York banking corporation, is a wholly owned subsidiary of Bankers
Trust New York Corporation.

INVESTMENT OBJECTIVES OF THE PORTFOLIOS. Below is a summary of the investment
objectives of the Portfolios of Fidelity's VIP Funds. There are no guarantees
that a Portfolio will be able to achieve its objective. YOU SHOULD READ
FIDELITY'S VIP FUNDS' PROSPECTUS CAREFULLY BEFORE INVESTING.

                              VIP MONEY MARKET PORTFOLIO

VIP Money Market Portfolio seeks to earn a high level of current income while
preserving capital and providing liquidity. It invests only in high-quality,
U.S. dollar denominated money market securities of domestic and foreign issuers,
such as certificates of deposit, obligations of governments and their agencies,
and commercial paper and notes.

                              VIP HIGH INCOME PORTFOLIO

VIP High Income Portfolio seeks a high current income by investing primarily in
high-yielding, lower rated, fixed-income securities, while also considering
growth of capital. It normally invests at least 65% of its total assets in
income-producing debt securities and preferred stocks, including convertible
securities, and up to 20% in common stocks and other equity securities. In view
of the types of securities in which this Portfolio invests, you should read the
complete risk disclosure for this Portfolio in its prospectus before investing
in it.


                                          13
<PAGE>

                             VIP EQUITY-INCOME PORTFOLIO

VIP Equity-Income Portfolio seeks reasonable income. The Portfolio will also
consider the potential for capital appreciation.  The Portfolio seeks a yield
which exceeds the composite yield on the securities comprising the S&P 500.  FMR
normally invests at least 65% of the Portfolio's total assets in
income-producing equity securities.

                                 VIP GROWTH PORTFOLIO

VIP Growth Portfolio seeks capital appreciation.  FMR invests the Portfolio's
assets in companies FMR believes have above-average growth potential.  Growth
may be measured by factors such as earnings or revenue.  Companies with high
growth potential tend to be companies with higher than average price/earnings
(P/E) ratios.  Companies with strong growth potential often have new products,
technologies, distribution channels or other opportunities for have a strong
industry market position.  The stocks of these companies are often called
"growth" stocks.

                                VIP OVERSEAS PORTFOLIO

VIP Overseas Portfolio seeks long-term growth of capital primarily through
investments in foreign securities. It normally invests at least 65% of its
assets in foreign securities.

                        VIP II INVESTMENT GRADE BOND PORTFOLIO

VIP II Investment Grade Bond Portfolio seeks as high a level of current income
while preserving capital by investing in a broad range of investment-grade
fixed-income securities.

                            VIP II ASSET MANAGER PORTFOLIO

VIP II Asset Manager Portfolio seeks high total return with reduced risk over
the long-term by allocating its assets among stocks, bonds and short-term money
market instruments.

                              VIP II INDEX 500 PORTFOLIO

VIP II Index 500 Portfolio seeks to provide investment results that correspond
to the total return (i.e., the combination of capital changes and income) of
common stocks publicly traded in the United States. In seeking this objective,
the Portfolio attempts to duplicate the composition and total return of the
Standard & Poor's 500 Composite Stock Price Index while keeping transaction
costs and other expenses low.

                             VIP II CONTRAFUND PORTFOLIO

VIP II Contrafund Portfolio seeks long-term capital appreciation.  FMR normally
invests the Portfolio's assets primarily in common stocks.  FMR invests the
Portfolio's assets in securities of companies whose value FMR believes is not
fully recognized by the public.  The types of companies in which the Portfolio
may invest include companies experiencing positive fundamental change such as a
new management team or product launch, a significant cost-cutting initiative, a
merger or acquisition, or a reduction in industry capacity that should lead to
improved pricing; companies whose earning potential has increased or is expected
to increase more than generally perceived; companies that have enjoyed recent
market popularity but which appear to have temporarily fallen out of favor for
reasons that are considered non-recurring or short-term; and companies that are
undervalued in relation to securities of other companies in the same industry.

                        VIP II ASSET MANAGER: GROWTH PORTFOLIO

VIP II Asset Manager: Growth Portfolio is an asset allocation fund that seeks to
maximize total return over the long term through investments in stocks, bonds,
and short-term money market instruments. The fund has a neutral mix, which
represents the way the fund's investments will generally be allocated over the
long term. The range and approximate neutral mix for each asset class are shown
below:

                        VIP III GROWTH OPPORTUNITIES PORTFOLIO

VIP III Growth Opportunities Portfolio seeks to provide capital growth.  FMR
normally invests the Portfolio's assets primarily in common stocks. FMR may also
invest the Portfolio's assets in other types of securities, including bonds,
which may be lower-quality debt securities.

                              VIP III BALANCED PORTFOLIO

VIP III Balanced Portfolio seeks both income and growth of capital by investing
in a diversified portfolio of equity and fixed-income securities.  It uses a
balanced approach to provide the best possible total return from investments in
foreign and domestic equity securities, convertible securities, preferred and
common stocks paying any combination of dividends and capital gains, and fixed
income securities.

                          VIP III GROWTH & INCOME PORTFOLIO

VIP III Growth & Income Portfolio seeks high total return through a combination
of current income and capital appreciation.  FMR normally invests a majority of
the Portfolio's assets in common stocks with a focus on those that pay current
dividends and show potential for capital appreciation.  FMR may also invest the
Portfolio's assets in bonds, including lower-quality debt securities, as well as
stocks that are not currently paying dividends, but offer prospects for future
income or capital appreciation.

                              VIP III MID CAP PORTFOLIO

FMR normally invests the VIP III Mid Cap Portfolio's assets primarily in common
stocks.  FMR normally invests at least 65% of the Portfolio's total assets in
securities of companies with medium market capitalizations.  Medium market
capitalization companies are those whose market capitalization is similar to the
capitalization of companies in the S&P Mid Cap 400 at the time of the
investment.  Companies whose capitalization no longer meets this definition
after purchase continue to be considered to have a medium market capitalization
for purposes of the 65% policy.

GUARANTEED RATE OPTION

FOR VARIOUS LEGAL REASONS, INTERESTS IN CONTRACTS ATTRIBUTABLE TO GUARANTEED
RATE OPTIONS HAVEN'T BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 ("1933
ACT"), OR THE INVESTMENT COMPANY ACT OF 1940 ("1940 ACT"). THUS, NEITHER THESE
CONTRACTS NOR OUR GENERAL ACCOUNT, WHICH GUARANTEES THE VALUES AND BENEFITS
UNDER THOSE CONTRACTS, ARE GENERALLY SUBJECT TO REGULATION UNDER THE PROVISIONS
OF THE 1933 ACT OR THE 1940 ACT. ACCORDINGLY, WE HAVE BEEN ADVISED THAT THE
STAFF OF THE SECURITIES AND EXCHANGE COMMISSION HASN'T REVIEWED THE DISCLOSURE
IN THIS PROSPECTUS RELATING TO THE GROS OR THE GENERAL ACCOUNT. DISCLOSURES
REGARDING THE GROS OR THE GENERAL ACCOUNT MAY, HOWEVER, BE SUBJECT TO CERTAIN
GENERALLY APPLICABLE PROVISIONS OF THE FEDERAL SECURITIES LAWS RELATING TO THE
ACCURACY AND COMPLETENESS OF STATEMENTS MADE IN PROSPECTUSES.

We offer GROs with durations of three, five, seven and ten years. We can change
the durations available from time to time. When you put money in a GRO, that
locks in a fixed effective annual interest rate that we declare (GUARANTEED
INTEREST RATE) for the duration you select (your GRO ACCOUNT).  The duration of
your GRO Account is the GUARANTEE PERIOD.  Each contribution or transfer to a
GRO establishes a new GRO Account for the duration you choose at the
then-current Guaranteed Interest Rate we declare. We won't declare an interest
rate less than 3%. Each GRO Account expires at the end of the duration you have
selected. See "Renewals of GRO Accounts" below. All contributions you make to a
GRO are placed in a non-unitized separate account.  Values and benefits under
your contract attributable to GROs are guaranteed by the reserves in our GRO
separate account as well as by our General Account.


                                          15
<PAGE>

The value of each of your GRO Accounts is referred to as a GRO VALUE. The GRO
Value at the expiration of the GRO Account, assuming you haven't transferred or
withdrawn any amounts, will be the amount you put in plus interest at the
Guaranteed Interest Rate. We credit interest daily at an effective annual rate
equal to the Guaranteed Interest Rate. We allocate interest at the end of each
contract year and at the time of any transfer, full or partial withdrawal,
payment of a death benefit or purchase of any annuity benefit.

We may declare a higher rate of interest in the first year for any Contribution
allocated to a GRO that exceeds the Guaranteed Interest Rate credited during the
rest of the Guarantee Period (ENHANCED RATE).  This Enhanced Rate will be
guaranteed for the Guaranteed Period's first year and declared at the time of
purchase.  We can declare and credit additional interest based on Contribution,
Account Value, withdrawal dates, economic conditions or on any other lawful,
nondiscriminatory basis (ADDITIONAL INTEREST).  Any Enhanced Rate and Additional
Interest credited to your GRO Account will be separate from the Guaranteed
Interest Rate and not used in the Market Value Adjustment formula.  THE ENHANCED
RATE OR ADDITIONAL INTEREST MAY NOT BE AVAILABLE IN CERTAIN STATES.

Each group of GRO Accounts of the same duration is considered one GRO.  For
example, all of your three-year GRO Accounts are one GRO while all of your
five-year GRO Accounts are another GRO.

You can get our current Guaranteed Interest Rates by calling our Administrative
Office.

ALLOCATIONS TO GROs CAN'T BE MADE UNDER CONTRACTS ISSUED IN CERTAIN STATES.

RENEWALS OF GRO ACCOUNTS. When a GRO Account expires, we'll set up a new GRO
Account for the same duration as your old one, at the then-current Guaranteed
Interest Rate, unless you withdraw your GRO Value or transfer it to another
Investment Option. We'll notify you in writing before your GRO Account expires.
You must tell us before the expiration of your GRO Accounts if you want to make
any changes.

The effective date of a renewal of a GRO Account will be the expiration date of
the old GRO Account. You will receive the Guaranteed Interest Rate that is in
effect on that date. If a GRO Account expires and it can't be renewed for the
same duration, the new GRO Account will be set up for the next shortest
available duration.  For example, if your expiring GRO Account was for 10 years
and when it expires, we don't offer a 10-year GRO, but we do offer a seven-year
GRO, your new one will be for seven years. If you want something different, you
can tell us within 30 days before the GRO Account expires.  You can't choose,
and we won't renew a GRO Account that expires after your Retirement Date.

MARKET VALUE ADJUSTMENTS. A MARKET VALUE ADJUSTMENT is an adjustment, either up
or down, that we make in your GRO Value if you make an early withdrawal or
transfer from your GRO Account. A Market Value Adjustment will be made for each
transaction made from a GRO Account other than your free withdrawals or those
made within 30 days before the expiration of the Account. There will be no
Market Value Adjustment made for a death benefit. The market adjusted value may
be higher or lower than the GRO Value, but will never be less than the MINIMUM
VALUE. Minimum Value is an amount equal to your contribution to the GRO Account
plus 3% interest, compounded annually, less previous withdrawals and less any
applicable contingent withdrawal charges. The Minimum Value for partial
withdrawals or transfers will be calculated on a pro-rata basis. Withdrawal
charges and the administrative expense charge could take away part of your
principal.

The Market Value Adjustment we make to your GRO Account is based on the changes
in our Guaranteed Interest Rate.  If our Guaranteed Interest Rate has increased
since the time of your investment, the Market Value Adjustment will reduce your
GRO Value (but not below the Minimum Value).  On the other hand, if our
Guaranteed Interest Rate has decreased since the time of your investment, the
Market Value Adjustment will increase your GRO Value.


                                          16
<PAGE>

The Market Value Adjustment (MVA) for a GRO Account is determined under the
following formula:

                                N/12                 N/12
     MVA =  GRO Value x [(1 + A)    / (1 + B + .0025)    - 1],  where

     A is the Guaranteed Interest Rate being credited to the GRO Account subject
     to the Market Value Adjustment,

     B is the current Guaranteed Interest Rate, as of the date of the Market
     Value Adjustment, for current allocations to a GRO Account, the length of
     which is equal to the number of whole months remaining in your GRO Account.
     Subject to certain adjustments, if that remaining period isn't equal to an
     exact period for which we have declared a new Guaranteed Interest Rate, B
     will be determined by a formula that finds a value between the Guaranteed
     Interest Rates for GRO Accounts of the next highest and next lowest
     durations.

     N is the number of whole months remaining in your GRO Account.

For contracts issued in certain states, the formula above will be adjusted to
comply with state requirements.

If the remaining term of your GRO Account is 30 days or less, the Market Value
Adjustment for your GRO Account will be zero. If for any reason we are no longer
declaring current Guaranteed Interest Rates, then to determine B we will use the
yield to maturity of United States Treasury Notes with the same remaining term
as your GRO Account, using a formula when necessary, in place of the current
Guaranteed Interest Rate or Rates.

   
For illustrations of the application of the Market Value Adjustment formula, see
Appendix B.
    
PART 4 - DEDUCTIONS AND CHARGES

SEPARATE ACCOUNT CHARGES

National Integrity deducts a daily expense amount from the unit value an amount
equal to an effective annual rate of 1.00% of the Account Value in the Variable
Account Options. This daily expense rate can't be increased without your
consent.

Of the 1.00% total charge, .05% of the value of each Variable Account Option is
used to reimburse us for administrative expenses not covered by the annual
administrative charge described below.  The remaining .95% is deducted for
National Integrity's assuming the expense risk (.65%) and the mortality risk
(.30%) under the contract. The expense risk is the risk that our actual expenses
of administering the contracts will exceed the annual administrative expense
charge. Mortality risk, as used here, refers to the risk National Integrity
takes that annuitants, as a class of persons, will live longer than estimated
and National Integrity will be required to pay out more annuity benefits than
anticipated. The relative proportion of the mortality and expense risk charges
may be changed, but the total .95% effective annual risk charge can't be
increased.

National Integrity may realize a gain from these daily charges if they aren't
needed to meet the actual expenses incurred.

OPTIONAL DEATH BENEFIT RIDER CHARGE

If you choose to receive the Optional Annual Stepped Up Death Benefit, an
additional daily charge at an annual rate of .25% is deducted from the Account
Value of each of your Variable Account Options.  This charge is designed to
reimburse us for increased expenses and mortality risks.

ANNUAL ADMINISTRATIVE CHARGE

If your Account Value is less than $50,000 on the last day of any contract year
before your Retirement Date, National Integrity charges an annual administrative
charge of $30. This charge is deducted pro-rata from your Account Value in each
Investment Option. The part of the charge deducted from the Variable Account
Options will reduce the number of units credited to you. The part of the charge
deducted from the GROs is withdrawn in dollars. The annual administrative charge
is pro-rated in the event of the Annuitant's retirement, death, or termination
of a contract during a contract year.


                                          17
<PAGE>

REDUCTION OR ELIMINATION OF SEPARATE ACCOUNT OR ADMINISTRATIVE CHARGES

We can reduce or eliminate the separate account or administrative charges for
individuals or groups of individuals if it saves us expenses.  We may do this
based on the size and type of the group and the amount of the contributions.

We won't unlawfully discriminate against any person or group if we reduce or
eliminate these charges.

PORTFOLIO CHARGES

The Separate Account buys shares of the Portfolios at net asset value. That
price reflects investment advisory fees and other direct expenses that have
already been deducted from the assets of the Portfolios. The amount charged for
investment management can't be increased without the approval of the
shareholders.

STATE PREMIUM TAX DEDUCTION

National Integrity won't deduct state premium taxes from your contributions
before investing them in the Investment Options, unless required to by your
state law. If the Annuitant elects an annuity benefit, we'll deduct any
applicable state premium taxes from the amount available for an annuity benefit.
State premium taxes currently range up to 4%.

CONTINGENT WITHDRAWAL CHARGE

We don't deduct sales charges when you make a contribution to the contract.
However, contributions withdrawn may be subject to a withdrawal charge of up to
7%.  As shown below, the charge varies, depending upon the "age" of the
contributions included in the withdrawal- that is, the number of years that have
passed since each contribution was made. The maximum percentage of 7% would
apply if the entire amount of the withdrawal consisted of contributions made
during your current contribution year. We don't deduct withdrawal charges when
you withdraw contributions made more than six years prior to your withdrawal. To
calculate the withdrawal charge, (1) the oldest contributions will be treated as
the first withdrawn and more recent contributions next, and (2) partial
withdrawals up to the free withdrawal amount aren't considered a withdrawal.
For partial withdrawals, the total amount deducted from your Account will
include the withdrawal amount requested, any Market Value Adjustment that
applies, and any withdrawal charge and administrative expense charge that apply,
so that the net amount you receive will be the amount you requested.

You may take up to 10% of your account value (less any earlier withdrawal in the
same year) each year without any contingent withdrawal charge or Market Value
Adjustment. This is referred to as your "free withdrawal."  If you don't take
any free withdrawals in one year, you can't add it to the next year's free
withdrawal.  If you aren't 59-1/2, federal tax penalties may apply.

We won't deduct a contingent withdrawal charge if you use the withdrawal to buy
from National Integrity either an immediate annuity benefit with life
contingencies or an immediate annuity without life contingencies with a
restricted prepayment option that provides for level payments over five or more
years.  Similarly, we won't deduct a charge if the Annuitant dies and the
withdrawal is made by the Annuitant's beneficiary. See "Death Benefits and
Similar Benefit Distributions" in Part 5.


                                          18
<PAGE>

Unless you tell us otherwise, we will make withdrawals (including any applicable
charges) from the Investment Options in the same proportion that you contributed
to them.  For example, if you have your contributions put into four different
Investment Options, your withdrawal will be taken in equal quarters from each
Account. You must withdraw at least $300.

REDUCTION OR ELIMINATION OF THE CONTINGENT WITHDRAWAL CHARGE

We can reduce or eliminate the contingent withdrawal charge individuals or a
group of individuals it saves us expenses.  We may do this based on the size and
type of the group and the amount of the contribution or whether there is some
relationship with National Integrity.  Examples of these relationships would
include being an employee of National Integrity or an affiliate, receiving
distributions or making internal transfers from other contracts issued by
Integrity, or making transfers of amounts held under qualified plans sponsored
by National Integrity or an affiliate. We won't unlawfully discriminate against
any person or group if we reduce or eliminate the contingent withdrawal charge.

TRANSFER CHARGE

If you make more than twelve transfers among your Investment Options during one
contract year, we may charge your account up to $20 for each additional transfer
during that year.  Transfer charges don't apply to transfers under (i) Dollar
Cost Averaging, (ii) Customized Asset Rebalancing, (iii) Asset Allocation and
Rebalancing, nor do these transfers count toward the twelve free transfers you
may make in a contract year.

HARDSHIP WAIVER

We can waive the Market Value Adjustment on any amounts withdrawn from the GRO
Accounts under hardship circumstances.  Hardship circumstances include the
Owner's (1) confinement to a nursing home, hospital or long term care facility,
(2) diagnosis of terminal illness with any medical condition which would result
in death or total disability, and (3) unemployment.  We can require reasonable
notice and documentation including, but not limited to, a physician's
certification and Determination Letter from a State Department of Labor.  Some
of the hardship circumstances listed above may not apply in some states, and, in
other states, may not be available at all.

TAX RESERVE

We can make a charge in the future for taxes or for reserves set aside for
taxes, which will reduce the investment experience of the Variable Account
Options.

PART 5 - TERMS OF YOUR VARIABLE ANNUITY

CONTRIBUTIONS UNDER YOUR CONTRACT

You can make contributions of at least $100 at any time up to the Annuitant's
Retirement Date. Your first contribution, however, can't be less than $1,000.
We'll accept contributions of at least $50 for salary allotment programs. We
have special rules for minimum contribution amounts for tax-favored retirement
programs. See "Special Rules for Tax-Favored Retirement Programs" in Part 7.

We may limit the total contributions under one contract to $1,000,000 if you are
under age 76 or to $250,000 if you are over age 76. Once you reach eight years
before your Retirement Date, we may refuse to accept any contribution.
Contributions may also be limited by various laws or prohibited by National
Integrity for all Annuitants under the contract. If your contributions are made
under a tax-favored retirement program, we won't measure them against the
maximum limits set by law.

Contributions are applied to the various Investment Options you select and are
used to pay annuity and death benefits.  Each contribution is credited as of the
date we have RECEIVED it (as defined below) at our Administrative Office both
the contribution and instructions for allocation among the Investment Options,
PROVIDED THAT AT ANY TIME YOU MAY NOT HAVE MONEY IN MORE THAN NINE INVESTMENT
OPTIONS. In determining the nine Investment Options, each of your GRO Accounts
counts as one Investment Option. Wire transfers of federal funds are deemed
received on the day of transmittal if credited to our account by 3 p.m. Eastern
Time, otherwise they are deemed received on the next Business Day.
Contributions by check or mail are deemed received when they are delivered


                                          19
<PAGE>

in good order to our Administrative Office.  A BUSINESS DAY is defined as any
day that the New York Stock Exchange is open.

You can change your choice of Investment Options at any time by writing to the
Administrative Office. The request should indicate your contract number and the
specific change you want to make, and you should sign the request. When the
Administrative Office receives it, the change will be effective for any
contribution that accompanies it and for all future contributions. We can also
accept changes by telephone transfer.  See "Transfers" in Part 5.

YOUR ACCOUNT VALUE

Your Account Value reflects various charges. See Part 4, "Deductions and
Charges."  Annual deductions are made as of the last day of each contract year.
Market Value Adjustments, if applicable, are made as of the effective date of
the transaction. Charges against our Separate Account are reflected daily. Any
amount allocated to a Variable Account Option will go up or down in value
depending on the investment experience of that Option. The value of
contributions made to the Variable Account Options isn't guaranteed. The value
of your contributions made to GROs is guaranteed, subject to any applicable
Market Value Adjustments. See "Guaranteed Rate Options" in Part 3.

YOUR PURCHASE OF UNITS IN OUR SEPARATE ACCOUNT

Allocations to the Variable Account Options are used to purchase units. On any
given day, the value you have in a Variable Account Option is the unit value
multiplied by the number of units credited to you in that Option. The units of
each Variable Account Option have different unit values.

The number of units purchased or redeemed (sold) in any Variable Account Option
is calculated by dividing the dollar amount of the transaction by the Option's
unit value, calculated after the close of business that day. The number of units
for a Variable Account Option at any time is the number of units purchased less
the number of units redeemed. The value of units fluctuates with the investment
performance of the corresponding Portfolios of the Portfolios, which in turn
reflects the investment income and realized and unrealized capital gains and
losses of the Portfolios, as well as the Portfolios' expenses. The unit values
also change because of deductions and charges we make to our Separate Account.
The number of units credited to you, however, won't vary because of changes in
unit values. Units of a Variable Account Option are purchased when you make new
contributions or transfer contributions you made before to that Option. Units
are redeemed when you make withdrawals or transfer amounts out of a Variable
Account Option. We also redeem units to pay the death benefit when the Annuitant
dies and to pay the annual administrative charge.

HOW WE DETERMINE UNIT VALUE

We determine unit values for each Variable Account Option on the Valuation Date.
The Valuation Date for purposes of determining unit values is 4 p.m. Eastern
Time on each day the New York Stock Exchange is open for business.

The unit value of each Variable Account Option for any day on which we determine
unit values is equal to the unit value for the last day on which a unit value
was determined multiplied by the net investment factor for that Option on the
current day. We determine a NET INVESTMENT FACTOR for each Option as follows:

 -   First, we take the value of the shares belonging to the Option in the
     corresponding Portfolio at the close of business that day (before giving
     effect to any transactions for that day, such as contributions or
     withdrawals). For this purpose, we use the share value reported to us by
     the Portfolios.

 -   Next, we add any dividends or capital gains distributions by the Portfolio
     on that day.

 -   Then, we charge or credit for any taxes or amounts set aside as a reserve
     for taxes.

 -   Then, we divide this amount by the value of the amounts in the Option at
     the close of business on the last day on which a unit value was determined
     (after giving effect to any transactions on that day).


                                          20
<PAGE>

 -   Finally, we subtract a daily asset charge for each calendar day since the
     last day on which a unit value was determined (for example, a Monday
     calculation will include charges for Saturday and Sunday). The daily charge
     is .00003721, which is an effective annual rate of 1.35%. This charge is
     for the mortality risk, administrative expenses and expense risk assumed by
     us under the contract.

Generally, this means that we adjust unit values to reflect what happens to the
Portfolio, and also for the mortality and expense risk charge and any charge for
administrative expenses or taxes.

TRANSFERS

You may transfer your Account Value among the Variable Account Options and the
GROs, subject to National Integrity's transfer restrictions. Transfers to a GRO
must be to a newly elected GRO (i.e. to a GRO you haven't already purchased) at
the then-current Guaranteed Interest Rate, unless we agree otherwise. Transfers
you make from a GRO Account, except within 30 days before your GRO Account
expires, are subject to a Market Value Adjustment. See "Guaranteed Rate Options"
in Part 3.  Transfers from GRO's will be made according to the order in which
money was originally allocated to the GRO.

The amount transferred must be at least $250 or, if less, the entire amount in
the Investment Option. You have twelve free transfers during a contract year.
After those twelve transfers, a charge of up to $20 may apply to each additional
transfer during that contract year. No charge will be made for transfers under
our Dollar Cost Averaging, Customized Asset Rebalancing, for the Asset
Allocation and Rebalancing Program programs, described in Part 8. Once annuity
payments begin, transfers aren't permitted.

You may request a transfer by writing to our Administrative Office. Each request
for a transfer must specify the contract number, the amounts to be transferred
and the Investment Options to and from which the amounts are to be transferred.
Transfers may also be arranged through our telephone transfer service if you
have established a Personal Identification Number (PIN CODE). We'll honor
telephone transfer instructions from any person who provides correct identifying
information.  We aren't responsible in the event of a fraudulent telephone
transfer if it is believed to be genuine in accordance with these procedures.
You bear the risk of loss if unauthorized persons make transfers on your behalf.

A transfer request is effective as of the Business Day our Administrative Office
receives it. A transfer request doesn't change the allocation of current or
future contributions among the Investment Options. Telephone transfers may be
requested from 9:00 a.m. - 5:00 p.m., Eastern Time, on any day we're open for
business. You'll receive the Variable Account Options' unit values as of the
close of business on the day you call. Transfer requests received after 4:00
p.m. Eastern Time (or the close of the New York Stock Exchange, if earlier) will
be processed using unit values as of the close of business on the next Business
Day after the day you call. All transfers will be confirmed in writing.

Transfer requests submitted by agents or market timing services that represent
multiple policies will be processed no later than the next Business Day after
our Administrative Office receives the requests.


                                          21
<PAGE>

WITHDRAWALS

You may make any number of withdrawals as often as you wish. Each withdrawal
must be for at least $300. The money will be taken from your Accounts in the
same proportions as you contributed it to them.  For example, if your
contributions are divided in equal 25% shares among four Investment Options,
when you make a withdrawal, 25% of the money withdrawn will come from each of
your Investment Options.  You can tell us if you want your withdrawal handled
differently.  During the first six years of your contract, there is a contingent
withdrawal charge for any withdrawals other than your free withdrawals.  The
charge starts at 7% and decreases depending on the age of your account.  This
charge is in addition to any Market Value Adjustments made to early withdrawals
from GRO Accounts.  Under some circumstances, the contingent withdrawal charge
and Market Value Adjustment may be waived.

When you make a partial withdrawal, the total amount deducted from your Account
Value will include the withdrawal amount requested plus any contingent
withdrawal charges and any Market Value Adjustments.  The total amount that you
receive will be the total that you requested.  Most of the withdrawals you make
before you are 59-1/2 years old are subject to a 10% federal tax penalty.  If
your contract is part of a tax-favored plan, the plan may limit your
withdrawals.  See "Tax Aspects of the Contracts" in Part 7.

ASSIGNMENTS

If your contract isn't part of a tax-favored program, you may assign the
contract before the Annuitant's Retirement Date. You can't, however, make a
partial assignment.  An assignment of the contract may have adverse tax
consequences. See Part 7, "Tax Aspects of the Contracts."  We won't be bound by
an assignment unless it is in writing and our Administrative Office has received
it.

DEATH BENEFITS AND SIMILAR BENEFIT DISTRIBUTIONS

We'll pay a death benefit to the Annuitant's surviving beneficiary (or
beneficiaries, in equal shares) if the last Annuitant dies before annuity
payments have started.  If the Annuitant dies at or over age 90 (or after the
Contract's 10th anniversary date, if later), the death benefit is the contract
account value at the end of the business day when we receive proof of death.
Similarly, if the Contract was issued on or after the youngest Annuitant's 86th
birthday, the death benefit is the contract account value at the end of the
business day when we receive proof of death.

For Contracts issued before the Annuitant's 86th birthday, if the Annuitant dies
before age 90 (or the Contract's 10th anniversary date, if later) before annuity
payments have started, the standard death benefit is the higher of:

     a)   the contract account value at the end of the business day when we
          receive proof of death; or
     b)   the total of all contributions;

each reduced on a pro rata basis for prior withdrawals (after being adjusted for
any applicable market value adjustments and/or charges).  We'll determine the
amount of the reduction by dividing the amount of the withdrawal by the annuity
account value on the transaction date and multiplying this percentage by the
then current guaranteed minimum death benefit.

If you choose the Optional Annual Stepped Up Death Benefit Rider, your death
benefit will be the highest of:

     a)   the contract account value at the end of the business day when we
          receive proof of death;
     b)   the total of all contributions; or
     c)   the highest contract account value on any contract anniversary which
          occurred before the Annuitant's 81st birthday and before the
          Annuitant's death, plus any subsequent contributions;

each reduced on a pro rata basis for prior withdrawals (after being adjusted for
any applicable market value adjustments and/or charges).  We'll determine the
amount of the reduction by dividing the amount of the withdrawal by the annuity
account value on the transaction date and multiplying this percentage by the
then current guaranteed minimum death benefit.


                                          22
<PAGE>

Death benefits and benefit distributions required because of a separate Owner's
death can be paid in a lump sum or as an annuity.  If a benefit option hasn't
been selected for the beneficiary at the Annuitant's death, the beneficiary can
select an option.

The Owner selects the beneficiary of the death benefit.  An Owner may change
beneficiaries by sending the appropriate form to the Administrative Office.  If
an Annuitant's beneficiary doesn't survive the Annuitant, then the death benefit
is generally paid to the Annuitant's estate.  No death benefit will be paid
after the Annuitant's death if there is a contingent Annuitant.  In that case,
the contingent Annuitant becomes the new Annuitant under the contract.

ANNUITY BENEFITS

All annuity benefits under your contract are calculated as of the Retirement
Date you select. You can change the Retirement Date by writing to the
Administrative Office any time before the Retirement Date. The Retirement Date
can't be later than your 90th birthday or earlier, if required by law. Contract
terms that apply to the various retirement programs, along with the federal tax
laws, establish certain minimum and maximum retirement ages.

Annuity benefits may be a lump sum payment or paid out over time as an annuity.
A lump sum payment will provide the Annuitant with the Cash Value under the
contract, shortly after the Retirement Date. The amount applied toward the
purchase of an annuity benefit will be the Adjusted Account Value, except that
the Cash Value will be the amount applied instead if the annuity benefit doesn't
have a life contingency and the term is less than five years.

ANNUITIES

Annuity benefits can provide for fixed or variable payments, which may be made
monthly, quarterly, semi-annually or annually. Variable payments will be funded
through one or more Separate Account Divisions.  For any annuity, the minimum
initial payment must be at least $20.

If you haven't already selected a form of annuity, within six months prior to
your Retirement Date we'll send you a notice form. You can tell us on the form
the type of annuity you want or confirm to us that we're to provide the normal
form of annuity, as defined below. However, if we don't receive a completed form
from you on or before your Retirement Date, we'll extend the Retirement Date
until we receive your written instructions at our Administrative Office. During
this extension, the values under your contract in the various Investment Options
will remain invested in those options and amounts remaining in Variable Account
Options will continue to be subject to the investment risks associated with
those Options. However, your Retirement Date can't be extended beyond your 90th
birthday or earlier, if required by law. You'll receive a lump sum benefit if
you don't make an election by then.

We currently offer the following types of annuities:

The NORMAL FORM OF ANNUITY is a fixed life income annuity with 10 years of
payments guaranteed, funded through our General Account.

A PERIOD CERTAIN ANNUITY provides for fixed or variable payments, or both, to
the Annuitant or the Annuitant's beneficiary (the PAYEE) for a fixed period. The
amount is determined by the period selected. If the payee dies before the end of
the period selected, the payee's beneficiary may elect to receive the total
present value of future payments in cash.

A PERIOD CERTAIN LIFE ANNUITY provides for fixed or variable payments, or both,
for at least the period selected and thereafter for the life of the payee or the
payee and another annuitant under a joint and survivor annuity. You can't change
or redeem the annuity once payments have begun. If the payee (or the payee and
the other annuitant under a joint and survivor annuity) dies before the period
selected ends, the remaining payments will go to another named payee.  That
payee can redeem the annuity and receive the present value of future guaranteed
payments in a lump sum.


                                          23
<PAGE>

A LIFE INCOME ANNUITY provides fixed payments for the life of the payee or for
the lives of the payee and another annuitant under a joint and survivor annuity.
Once a life income annuity is selected, the form of annuity can't be changed or
redeemed for a lump sum payment by the Annuitant or any payee.

ANNUITY PAYMENTS

Fixed annuity payments won't change and are based upon annuity rates provided in
your contract. The size of payments will depend on the form of annuity that was
chosen and, in the case of a life income annuity, on the payee's age (or payee
and a joint annuitant in the case of a joint and survivor annuity) and sex
(except under most tax-favored retirement programs). If our annuity rates then
in effect would yield a larger payment, those rates will apply instead of the
tables.

Variable annuity payments are funded only in the Separate Account Divisions
through the purchase of annuity units. The Variable Account Option or Options
selected can't be changed after annuity payments begin.  The Statement of
Additional Information (SAI) has more information about the determination of
annuity payments.  The number of units purchased is equal to the amount of the
first annuity payment divided by the new annuity unit value for the valuation
period that includes the due date of the first annuity payment.  The amount of
the first annuity payment is determined in the same manner for a variable
annuity as it is for a fixed annuity. The number of annuity units stays the same
for the annuity payment period but the new annuity unit value changes to reflect
the investment income and the realized and unrealized capital gains and losses
of the Variable Account Option or Options selected, after charges made against
it. Annuity unit values assume a base rate of net investment return of 5%,
except in states which require a lower rate in which case 3.5% will be used.
The annuity unit value will rise or fall depending on whether the actual rate of
net investment return is higher or lower than the assumed base rate. In the SAI,
see "Determination of Annuity Unit Values."

If the age or sex of an annuitant has been misstated, any benefits will be those
that would have been purchased at the correct age and sex. Any overpayments or
underpayments made by us will be charged or credited with interest at the rate
of 6% per year. If we have made overpayments because of incorrect information
about age or sex, we'll deduct the overpayment from the next payment or payments
due. We add underpayments to the next payment.

TIMING OF PAYMENT

We normally make payments from the Variable Account Options, or apply your
Adjusted Account Value to the purchase of an annuity within seven days after we
receive the required form at our Administrative Office. Our action can be
deferred, however, for any period during which

(1)  the New York Stock Exchange  has been closed or trading on it is
     restricted;

(2)  an emergency exists so that disposal of securities isn't reasonably
     practicable or it isn't reasonably practicable for a Separate Account
     fairly to determine the value of its net assets; or

(3)  the SEC, by order, permits us to defer action in order to protect persons
     with interests in the Separate Account. We can defer payment of your GROs
     for up to six months, and interest will be paid on any such payment delayed
     for 30 days or more.

HOW YOU MAKE REQUESTS AND GIVE INSTRUCTIONS

When you write to our Administrative Office, use the address on the first page
of this prospectus. We can't honor your requests unless they are in proper and
complete form. Whenever possible, use one of our printed forms, which you can
get from our Administrative Office.

PART 6 - VOTING RIGHTS

VOTING RIGHTS

National Integrity is the legal owner of the shares of the Portfolios held by
the Separate Account and, as such, has the right to vote on certain matters.
Among other things, we may vote to elect the Portfolios' Boards of Directors, to
ratify the selection of independent auditors for the Portfolios, and on any
other matters described in the Portfolios' current prospectus or requiring a
vote by shareholders under the 1940 Act.

Whenever a shareholder vote is taken, we give you the opportunity to tell us how
to vote the number of shares purchased as a result of contributions to your
contract. We'll send you Portfolio proxy materials and a form for giving us
voting instructions.

If we don't receive instructions in time from all Owners, we'll vote shares in a
Portfolio for which no instructions have been received in the same proportion as
we vote shares for which we have received instructions. Under eligible deferred
compensation plans and certain Qualified Plans, your voting instructions must be
communicated to us indirectly, through your employer, but we aren't responsible
for any failure by your employer to ask for your instructions or to tell us what
your instructions are. We'll vote any Portfolio shares that we're entitled to
vote directly, because of amounts we have accumulated in our Separate Account,
in the same proportions that other Owners vote. If the federal securities laws
or regulations or interpretations of them change so that we are permitted to
vote shares of the Portfolios in our own right or to restrict Owner voting, we
may do so.

HOW WE DETERMINE YOUR VOTING SHARES

You vote only on matters concerning the Portfolios in which your contributions
have been invested. We determine the number of Portfolio shares in each Variable
Account Option under your contract by dividing the amount of your Account Value
allocated to that Option by the net asset value of one share of the
corresponding Portfolio as of the record date set by the Portfolios' Boards for
the shareholders' meeting. We count fractional shares. The record date for this
purpose can't be more than 60 days before the shareholders' meeting. After
annuity payments have begun, voting rights are calculated in a similar manner
based on the actuarially determined value of your interest in each Variable
Account Option.

HOW PORTFOLIO SHARES ARE VOTED

All Portfolio shares are entitled to one vote; fractional shares have fractional
votes. Voting is on a Portfolio-by-Portfolio basis, except for certain matters
(for example, election of Directors) that require collective approval. On
matters where the interests of the individual Portfolios differ, the approval of
the shareholders in one Portfolio isn't needed to make a decision in another
Portfolio. If shares of the Portfolios are sold to separate accounts of other
insurance companies, the shares voted by those companies in accordance with
instructions received from their contract holders will dilute the effect of
voting instructions received by National Integrity from its Owners.

SEPARATE ACCOUNT VOTING RIGHTS

Under the 1940 Act, certain actions (such as some of those described under
"Changes in How We Operate" in Part 2) may require Owner approval. In that case,
you'll be entitled to a number of votes based on the value you have in the
Variable Account Options, as described above under "How We Determine Your Voting
Shares."  We'll cast votes attributable to amounts we have in the Variable
Account Options in the same proportions as votes cast by Owners.


                                          25

PART 7 - TAX ASPECTS OF THE CONTRACTS

INTRODUCTION

The effect of federal income taxes on the amounts held under a contract, on
annuity payments, and on the economic benefits to the Owner, Annuitant, and the
beneficiary or other payee may depend on National Integrity's tax status, on the
type of retirement plan, if any, for which the contract is purchased, and upon
the tax and employment status of the individuals concerned.

The following discussion of the federal income tax treatment of the contract
isn't designed to cover all situations and isn't intended to be tax advice. It's
based upon our understanding of the present federal income tax laws as currently
interpreted by the Internal Revenue Service (IRS) and various courts. We can't
guarantee that the tax code or the courts will or won't change their views on
the treatment of these contracts. Future legislation may affect annuity
contracts adversely. Moreover, we haven't attempted to consider any applicable
state or other tax laws. Because of the complexity of tax laws and the fact that
tax results will vary according to the particular circumstances, any one
considering buying a contract, or selecting annuity payments under the contract,
or receiving annuity payments under a contract should consult a qualified tax
adviser. NATIONAL INTEGRITY DOESN'T MAKE ANY GUARANTEE REGARDING THE TAX STATUS,
FEDERAL, STATE, OR LOCAL, OF ANY CONTRACT OR ANY TRANSACTION INVOLVING THE
CONTRACTS.

TAX STATUS OF NATIONAL INTEGRITY

National Integrity is taxed as a life insurance company under Part I of
Subchapter L of the Internal Revenue Code of 1986, as amended (the CODE).  Since
the Separate Accounts aren't separate entities from National Integrity and their
operations form a part of National Integrity, they aren't taxed separately as
"regulated investment companies" under Subchapter M of the Code.  Investment
income and realized capital gains on the assets of the Separate Accounts are
reinvested and taken into account in determining the accumulation value.  Under
existing federal income tax law, the Separate Accounts' investment income,
including realized net capital gains, isn't taxed to National Integrity.
National Integrity can make a tax deduction if federal tax laws change to
include these items in our taxable income.

YOUR CONTRACT IS AN ANNUITY

Under federal tax law, anyone can purchase an annuity with after-tax dollars and
your annuity earnings won't be taxed until you make a withdrawal. Or, an
individual (or employer) may buy the annuity to fund a tax-favored retirement
program (contributions are with pre-tax dollars), such as an IRA or qualified
plan.  Finally, the individual (or employer) may buy the Annuity to fund a Roth
IRA (contributions are with after-tax dollars and earnings are excluded in
taxable income at distribution).

This prospectus covers the basic tax rules that apply to an annuity purchased
directly with after-tax dollars, (NONQUALIFIED ANNUITY), and some of the special
tax rules that apply to an annuity purchased to fund a tax-favored retirement
program (QUALIFIED ANNUITY). A qualified annuity may restrict your rights and
benefits to qualify for its special treatment under the federal tax law.

TAXATION OF ANNUITIES GENERALLY

Section 72 of the Code governs the taxation of annuities. In general,
contributions you put into the annuity (your "basis" or "investment" in the
contract) won't be taxed when you receive the amounts back in a distribution.
Also, an Owner isn't taxed on the annuity's earnings until some form of
withdrawal or distribution is made under the contract. However, under certain
circumstances, the increase in value may be subject to current federal income
tax. For example, corporations, partnerships, and other non-natural persons
can't defer tax on the annuity's income unless an exception applies. In
addition, if an Owner transfers an annuity as a gift to someone other than a
spouse (or former spouse), all increases in its value are taxed at the time of
transfer. The assignment or pledge of any portion of the value of a contract
will be treated as a distribution of that portion of the value of the contract.

You can take withdrawals from the contract or you can wait to annuitize it when
the annuitant reaches a certain age.  The tax implications are different for
each type of distribution.  Section 72 of the Code says that the proceeds of a
full or partial withdrawal from a contract before annuity payments begin are
treated first as taxable income,


                                          26
<PAGE>

but only to the extent of the increase of the Account Value. The rest of the
withdrawal, representing your basis in the annuity, isn't taxable. Generally,
the investment or basis in the contract equals the contributions made by you or
on your behalf, minus any amounts previously withdrawn that weren't treated as
taxable income. Special rules may apply if the contract includes contributions
made prior to August 14, 1982 that were rolled over to the contract in a
tax-free exchange.

If you take annuity payments over the lifetime of the annuitant, part of each
payment is considered to be a tax-free return of your investment. This
non-taxable portion of each payment is figured using a ratio of the Owner's
investment to his or her expected return under the contract (exclusion Ratio).
Once you get the tax-free part, the rest of each payment will be considered the
increase of your Account Value, and is ordinary income.  When all of these
tax-free portions add up to your investment in the annuity, future payments are
all counted as an increase in your Account Value, and are taxable income.  If
the Annuitant dies before recovering the total investment, a deduction for the
remaining basis will generally be allowed on the Owner's final federal income
tax return.

We may be required to withhold federal income taxes on all distributions unless
the eligible recipients elect not to have any amounts withheld and properly
notify National Integrity of that election.

The taxable portion of a distribution is treated as ordinary income and is taxed
at ordinary income tax rates. In addition, you may be subject to a tax penalty
of 10% on the taxable portion of a distribution unless it is:

     (1)  on or after the date on which the taxpayer attains age 59-1/2;
     (2)  as a result of the death of the Owner;
     (3)  part of a series of substantially equal periodic payments (paid at
          least annually) for the life (or life expectancy) of the taxpayer or
          joint lives (or joint life expectancies) of the taxpayer and
          beneficiary;
     (4)  attributable to the taxpayer becoming disabled within the meaning of
          Code Section 72(m)(7);
     (5)  from certain qualified plans (note, however, other penalties may
          apply);
     (6)  under a qualified funding asset (as defined in Section 130(d) of the
          Code);
     (7)  purchased by an employer on termination of certain types of qualified
          plans and held by the employer until the employee separates from
          service;
     (8)  under an immediate annuity as defined in Code Section 72(u)(4); or
     (9)  purchase of a first home (distribution up to $10,000)
     (10) for certain higher education expenses; or
     (11) to cover certain deductible medical expenses.

Please note that items (9), (10) and (11) apply to IRAs only).

Any withdrawal provisions of your contract will also apply.  See "Withdrawals"
in Section 5.

All annuity contracts issued by National Integrity or its affiliates to one
Annuitant during any calendar year are treated as a single contract in measuring
the taxable income that results from surrenders and withdrawals under any one of
the contracts.

DISTRIBUTION-AT-DEATH RULES

Under section 72(s) of the Code, to be treated as an annuity, a contract must
provide the following distribution rules:  (a) if any Owner dies on or after the
Retirement Date and before the entire interest in the contract has been
distributed, then the rest of that annuity must be distributed at least as
quickly as the method in effect when the owner died; and (b) if any Owner dies
before the Retirement Date, the entire interest in the contract must be
distributed within five years. However, any interest that is payable to a death
beneficiary may be annuitized over the life of that beneficiary or over a period
not extending beyond the life expectancy of that beneficiary, so long as
distributions begin within one year after the Owner's death. If the beneficiary
is the Owner's spouse, the contract (along with the deferred tax status) may be
continued in the spouse's name as the Owner.

DIVERSIFICATION STANDARDS

National Integrity manages the investments in the annuities under Section 817(h)
of the Code to ensure that will be taxed as described above.


                                          27

TAX-FAVORED RETIREMENT PROGRAMS

An owner can use this annuity with certain types of retirement plans that
receive favorable treatment under the Code.  Numerous tax rules apply to the
participants in qualified plans and to the contracts used in connection with
those qualified plans.  These tax rules vary according to the type of plan and
the terms and conditions of the plan itself.  Owners, Annuitants, and
beneficiaries are cautioned that the rights of any person to any benefits under
qualified plans may be subject to the terms and conditions of the plans
themselves, regardless of the terms and conditions of the contract. In addition,
loans from qualified contracts, where allowed, are subject to a variety of
limitations, including restrictions as to the amount that may be borrowed, the
duration of the loan, and the manner in which the loans must be repaid. (Owners
should always consult their tax advisors and retirement plan fiduciaries before
taking any loans from the plan.) Special rules also apply to the time at which
distributions must begin and the form in which the distributions must be paid.
THE STATEMENT OF ADDITIONAL INFORMATION CONTAINS GENERAL INFORMATION ABOUT THE
USE OF CONTRACTS WITH THE VARIOUS TYPES OF QUALIFIED PLANS.

FEDERAL AND STATE INCOME TAX WITHHOLDING

Certain states have indicated that pension and annuity withholding will apply to
payments made to residents. Generally, an election out of federal withholding
will also be considered an election out of state withholding. For more
information concerning a particular state, call our Administrative Office at the
toll-free number.

IMPACT OF TAXES TO NATIONAL INTEGRITY

The contracts allow National Integrity to charge the Separate Account for taxes.
National Integrity can also set up reserves for taxes.

TRANSFERS AMONG INVESTMENT OPTIONS

There won't be any tax liability if you transfer any part of the Account Value
among the Investment Options of your contract.

PART 8 - ADDITIONAL INFORMATION

SYSTEMATIC WITHDRAWALS

We offer a program that allows you to pre-authorize periodic withdrawals from
your contract prior to your Retirement Date. You can choose to have withdrawals
made monthly, quarterly, semi-annually or annually and can specify the day of
the month (other than the 29th, 30th or 31st) on which the withdrawal is to be
made. You may specify a dollar amount for each withdrawal or an annual
percentage to be withdrawn. The minimum systematic withdrawal currently is $100.
You may also specify an account for direct deposit of your systematic
withdrawals. To enroll in our systematic withdrawal program, send the
appropriate form to our Administrative Office. Withdrawals may begin one
business day after we receive the form. You may terminate your participation in
the program upon one day's prior written notice, and we may terminate or change
the systematic withdrawal program at any time. If on any withdrawal date you
don't have enough money in your Account to make all of the withdrawals you have
specified, no withdrawal will be made and your enrollment in the program will be
ended.

Amounts you withdraw under the systematic withdrawal program may be within the
free withdrawal amount.  If so, we won't deduct a contingent withdrawal charge
and no Market Value Adjustment will be made.  See "Contingent Withdrawal Charge"
in Part 4.  Amounts withdrawn under the systematic withdrawal program in excess
of the free withdrawal amount will be subject to a contingent withdrawal charge,
an administrative expense charge and a Market Value Adjustment, if applicable.
Withdrawals also may be subject to the 10% federal tax penalty for early
withdrawals under the contracts and to income taxation.  See Part 7, "Tax
Aspects of the Contracts."

INCOME PLUS WITHDRAWAL PROGRAM

We offer an Income Plus Withdrawal Program that allows you to pre-authorize
substantially equal periodic withdrawals, based on your life expectancy, from
your contract prior to your reaching age 59-1/2.  You won't have


                                          28
<PAGE>

to pay any tax penalty for these withdrawals, but they will be subject to
ordinary income tax.  See "Taxation of Annuities Generally," in Section 7.  Once
you begin receiving distributions, they shouldn't be changed or stopped until
the later of:

- -    the date you reach age 59-1/2;  or
- -    five years from the date of the first distribution.

If you change or stop the distribution or take an additional withdrawal, you may
have to pay a 10% penalty tax that would have been due on all prior
distributions before you reached age 59-1/2 made under the Income Plus Program
and for any interest.

You can choose the Income Plus Withdrawal Program any time before you reach age
59-1/2.  You can elect this option by sending the election form to our
Administrative Office.  You may choose to have withdrawals made monthly,
quarterly, semi-annually or annually and may specify the day of the month (other
than the 29th, 30th or 31st) on which the withdrawal is to be made. We'll
calculate the amount of the distribution under a method you select, subject to a
minimum, which is currently $100.  You must also specify an account for direct
deposit of your Income Plus Withdrawals.

To enroll in our Income Plus Withdrawal Program, send the appropriate form to
our Administrative Office. Your withdrawals may begin at least one Business Day
after we receive your form. You may end your participation in the program upon
seven Business Day's prior written notice, and we may terminate or change the
Income Plus Program at any time. If on any withdrawal date you don't have enough
money to make all of the withdrawals you have specified, no withdrawal will be
made and your enrollment in the program will be ended. This program isn't
available in connection with the Systematic Withdrawal Program, Dollar Cost
Averaging, or Asset Allocation and Rebalancing Program.

If you haven't used up your free withdrawals in any given contract year, amounts
you withdraw under the Income Plus Withdrawal Program may be within the free
withdrawal amount.  If they are, no contingent withdrawal charge or Market Value
Adjustment will be made.  See "Contingent Withdrawal Charge" in Part 4.  Amounts
withdrawn under the Income Plus Withdrawal Program in excess of the free
withdrawal amount will be subject to a contingent withdrawal charge and a Market
Value Adjustment if applicable.

DOLLAR COST AVERAGING

We offer a dollar cost averaging program under which we transfer contributions
that you have made to the VIP Money Market Option on a monthly, quarterly,
semi-annual or annual basis to one or more other Variable Account Options. You
must tell us how much you want to be transferred into each Variable Account
Option.  The current minimum transfer to each Option is $250. We won't charge a
transfer charge under our dollar cost averaging program, and these transfers
won't count towards your twelve free transfers.

To enroll in our dollar cost averaging program, send the appropriate form to our
Administrative Office.  You may terminate your participation in the program upon
one day's prior written notice, and we may terminate or change the dollar cost
averaging program at any time. If you don't have enough money in the VIP Money
Market Option to transfer to each Variable Account Option specified, no transfer
will be made and your enrollment in the program will be ended.

CUSTOMIZED ASSET REBALANCING

We offer a Customized Asset Rebalancing program that allows you to determine how
often rebalancing occurs. You can choose to rebalance monthly, quarterly,
semi-annually or annually. The value in the Variable Account Options will be
automatically rebalanced by transfers among the Variable Account Options, and
you will receive a confirmation notice after each rebalancing. Transfers will
occur only to and from those Variable Account Options where you have current
contribution allocations. We won't charge a transfer charge for transfers under
our Customized Asset Rebalancing program, and these transfers won't count
towards your twelve free transfers.

GROs aren't eligible for the Customized Asset Rebalancing program.


                                          29
<PAGE>

To enroll in our Customized Asset Rebalancing program, send the appropriate form
to our Administrative Office. You should be aware that other allocation
programs, such as dollar cost averaging, as well as transfers and withdrawals
that you make, may not work with the Customized Asset Rebalancing program. You
should, therefore, monitor your use of other programs, transfers, and
withdrawals while the Customized Asset Rebalancing program is in effect. You may
terminate your participation in the program upon one day's prior written notice,
and we may terminate or change the Customized  Asset Rebalancing program at any
time.

ASSET ALLOCATION AND REBALANCING PROGRAM
   
We offer an Asset Allocation and Rebalancing Program developed in 
consultation with Callan Associates. Callan Associates is an independent 
research and consulting firm, specializing in the strategic asset allocation 
decision.
    
You may select one of five proposed Asset Allocation Rebalancing Models:
Conservative, Moderately Conservative, Moderate, Moderately Aggressive, or
Aggressive.  The contributions you are making will initially be allocated among
the Options established for each Model.  If we change the Model, your account
values will be automatically reallocated accordingly unless you have terminated
your participation.  You and your financial representative also have the option
to design a program that is tailored to your specific retirement needs.

When you select this program, your account values will be allocated and your
variable portfolios will be rebalanced automatically at least annually.  The
program automatically applies to all contributions made to your annuity contract
while you are still participating.  You will receive a confirmation notice after
each rebalancing.  We won't charge a transfer charge for transfers made under
the Asset Allocation and Rebalancing Program.  These transfers won't count
toward your twelve free transfers.

In each Asset Allocation Rebalancing Model, a part of all contributions is
allocated to a five-year Guaranteed Rate Option (GRO).  The amount allocated to
the GRO won't be reallocated or rebalanced while you are participating in a
specific Model.  You may cancel or change the Model you have selected at any
time. If you withdraw or transfer your GRO funds, they may be subject to a
Market Value Adjustment that may increase or decrease your account value.

To enroll in the Asset Allocation and Rebalancing Program, complete the
appropriate form and send it to our Administrative office.  You should be aware
that other allocation programs, such as dollar cost averaging, transfers and
withdrawals that you make, may not work with the Customized Asset Rebalancing
program. If, after selecting one of the five models, you request a transaction
that results in a reallocation outside one of the Models, your participation in
the Model program automatically ends.  You should, therefore, monitor your use
of other programs, transfers, and withdrawals while the Customized Asset
Rebalancing program is in effect.  This program isn't available with the
Customized Asset Rebalancing program. We can terminate or change this program in
whole or in part, or restrict contributions to the program.  This program may
not be available in all states.

You may terminate participation in this program upon one day's prior written
notice.

SYSTEMATIC CONTRIBUTIONS

We offer a program for systematic contributions that allows you to pre-authorize
monthly withdrawals from your checking account for payment to us. To enroll in
this program, send the appropriate form to our Administrative Office. You may
terminate your participation in the program upon 30 days' prior written notice.
We may terminate your participation if your bank declines to make any payment.
The minimum amount for systematic contributions is $100 per month.

PERFORMANCE INFORMATION

Performance data for the Variable Account Options, including the yield and
effective yield of the VIP Money Market Option, the yield of the other Options,
and the total return of all of the Options may appear in advertisements or sales
literature. This performance data is based only the performance of a
hypothetical investment in that Option during the particular time period on
which the calculations are based. Performance information should be considered
in light of the investment objectives and policies of the Portfolio in which the
Option invests and the market conditions during the given time frame.  It
shouldn't be considered as a representation of performance to be achieved in the
future.


                                          30
<PAGE>

TOTAL RETURNS are based on the overall dollar or percentage change in value of a
hypothetical investment in an Option. Total return information reflects changes
in Portfolio share price, the automatic reinvestment of all distributions and
the deduction of contract charges and expenses that may apply. Total returns
also may be shown that don't take into account the contingent withdrawal charge
or the annual administrative charge that is applied when the Account Value is
less than $50,000 at the end of the contract year.

CUMULATIVE TOTAL RETURNS show an Investment Option's performance over a specific
period of time, usually seven years. An AVERAGE ANNUAL TOTAL RETURN shows the
hypothetical yearly return that would have produced the same cumulative total
return if the Investment Option experienced exactly the same return each year
for the entire period shown. Because performance will fluctuate on a
year-by-year basis, the average annual total returns tend to show a smooth
result that won't mirror actual performance, even though the end result will be
the same.

Some Investment Options may also advertise YIELD, which shows the income
generated by an investment in that particular Option over a specified period of
time. This income is annualized and shown as a percentage. Yields don't take
into account capital gains or losses or the contingent withdrawal charge that
may apply if you withdraw your money at the end of the hypothetical period.

The VIP Money Market Option may advertise its CURRENT and EFFECTIVE YIELD.
Current yield reflects the income generated by an investment in that Option over
a specified seven-day period. Effective yield is calculated in a similar manner
except that it assumes that the income earned is reinvested, and the income on
the reinvested amount is included. The VIP II Investment Grade Bond and VIP High
Income Option may advertise a 30-day yield which reflects the income generated
by an investment in that Option over a specified 30-day period.

For a detailed description of the methods used to determine yield and total
return for the Variable Account Options, see the Statement of Additional
Information.

FINANCIAL INFORMATION

No condensed financial information is provided for any of the Variable Account
Options because as of the date of this Prospectus the Options hadn't started
operations.  The unit value for each Investment Option at inception will be
$10.00.  The inception date for each of the Variable Account Options is May 1,
1999.

                                      APPENDIX B

                      ILLUSTRATION OF A MARKET VALUE ADJUSTMENT

                    Contribution:                 $50,000.00

                    GRO Account duration:      7 Years

                    Guaranteed Interest Rate:  5% Annual Effective Rate

The following examples illustrate how the Market Value Adjustment may affect the
values of a contract upon a withdrawal. The 5% assumed Guaranteed Interest Rate
is the same rate used in the Example under "Table of Annual Fees and Expenses"
in this Prospectus. In these examples, the withdrawal occurs three years after
the initial contribution. The Market Value Adjustment operates in a similar
manner for transfers. No contingent withdrawal charge applies to transfers.

The GRO Value for this $50,000 contribution is $70,355.02 at the expiration of
the GRO Account. After three years, the GRO Value is $57,881.25. It is also
assumed, for the purposes of these examples, that no prior partial withdrawals
or transfers have occurred.

The Market Value Adjustment will be based on the rate we are then crediting (at
the time of the withdrawal) on new contributions to GRO Accounts of the same
duration as the time remaining in your GRO Account, rounded to the next higher
number of complete months. If we don't declare a rate for the exact time
remaining, we will interpolate between the Guaranteed Interest Rates for GRO
Accounts of durations closest to (next higher and next lower) the remaining
period described above. Three years after the initial contribution, there would
have been four years remaining in your GRO Account. These examples also show the
withdrawal charge that would be calculated separately.

EXAMPLE OF A DOWNWARD MARKET VALUE ADJUSTMENT:

A downward Market Value Adjustment results from a full or partial withdrawal
that occurs when interest rates have increased. Assume interest rates have
increased three years after the initial contribution and we are then crediting
6.25% for a four-year GRO Account. Upon a full withdrawal, the Market Value
Adjustment, applying the above formula would be:

     -0.0551589 = [(1 + .05) to the power of 48/12 / (1 + .0625 + .0025) to the
     power of 48/12] - 1

The Market Value Adjustment is a reduction of $3,192.67 from the GRO Value:

     -$3,192.67 = -0.0551589 X $57,881.25

The Market Adjusted Value would be:

     $54,688.58 = $57,881.25 - $3,192.67

A withdrawal charge of 5% would be assessed against the $50,000 original
contribution:

     $2,500.00 = $50,000.00 X .05

Thus, the amount payable on a full withdrawal would be:

     $52,188.58 = $57,881.25 - $3,192.67 - $2,500.00

If instead of a full withdrawal, $20,000 was requested, we would first determine
the free withdrawal amount:

     $5,788.13 = $57,881.25 X .10

The non-free amount would be:


                                          33
<PAGE>

     $14,211.87 = $20,000.00 - $5,788.13

The Market Value Adjustment, which is only applicable to the non-free amount,
would be

     - $783.91 = -0.0551589 X $14,211.87

The withdrawal charge would be:

     $789.25 = [($14,211.87+ $783.91)/(1 - .05)] - ($14,211.87+ 783.91)

Thus, the total amount needed to provide $20,000 after the Market Value
Adjustment and withdrawal charge would be:

     $21,573.16 = $20,000.00 + $783.91 + $789.25

The ending Account Value would be:

     $36,308.09 = $57,881.25 - $21,573.16

EXAMPLE OF AN UPWARD MARKET VALUE ADJUSTMENT:

An upward Market Value Adjustment results from a full or partial withdrawal that
occurs when interest rates have decreased. Assume interest rates have decreased
three years after the initial contribution and we are then crediting 4% for a
four-year GRO Account. Upon a full withdrawal, the Market Value Adjustment,
applying the formula set forth in the prospectus, would be:

     .0290890 = [(1 + .05) to the power of 48/12 / (1 + .04 + .0025) to the
     power of 48/12] - 1

The Market Value Adjustment is an increase of $1,683.71 to the GRO Value:

     $1,683.71 = .0290890 X $57,881.25

The Market Adjusted Value would be:

     $59,564.96 = $57,881.25 + $1,683.71

A withdrawal charge of 5% would be assessed against the $50,000 original
contribution:

     $2,500.00 = $50,000.00 X .05

Thus, the amount payable on a full withdrawal would be:

     $57,064.96 = $57,881.25 + $1,683.71 - $2,500.00

If instead of a full withdrawal, $20,000 was requested, the free withdrawal
amount and non-free amount would first be determined as above:

         Free Amount =    $ 5,788.13

     Non-Free Amount =    $14,211.87

The Market Value Adjustment would be:

     $413.41 = .0290890 X $14,211.87

The withdrawal charge would be:


                                          34
<PAGE>

     $726.23 = [($14,211.87 - $413.41)/(1 - .05)] - ($14,211.87 - $413.41)

Thus, the total amount needed to provide $20,000 after the Market Value
Adjustment and withdrawal charge would be:

     $20,312.82 = $20,000.00 - $413.41 + $726.23

The ending Account Value would be:

     $37,568.43 = $57,881.25 - $20,312.82

Actual Market Value Adjustments may have more or less impact than shown in the
examples, depending on the actual change in interest crediting rate and the
timing of the withdrawal or transfer in relation to the time remaining in the
GRO Account.  Also, the Market Value Adjustment can never decrease the Account
Value below premium plus 3% interest, before any applicable charges.  Account
values less than $50,000 will be subject to a $30 annual charge.

PART 1 - NATIONAL INTEGRITY AND CUSTODIAN

National Integrity Life Insurance Company is a New York stock life insurance
company that sells life insurance and annuities. Its principal executive offices
are located at 15 Matthews Street, Suite 200, Goshen, NY 10924. National
Integrity, the depositor of Separate Account I, is a wholly owned subsidiary of
Integrity Life Insurance Company, an Ohio corporation. All outstanding shares of
Integrity Life Insurance Company are owned by ARM Financial Group, Inc. (ARM), a
Delaware corporation that's a financial services company focusing on the
long-term savings and retirement marketplace by providing retail and
institutional products and services throughout the United States. ARM owns 100%
of the stock of (i) ARM Securities Corporation (ARM SECURITIES), a Minnesota
corporation, registered with the SEC as a broker-dealer and a member of the
National Association of Securities Dealers, Inc., (ii) Integrity Capital
Advisors, Inc., a Delaware corporation registered with the SEC as an investment
adviser, (iii) SBM Certificate Company, a Minnesota corporation registered with
the SEC as an issuer of face-amount certificates, and (iv) ARM Transfer Agency,
Inc., a Delaware corporation registered with the SEC as a transfer and dividend
disbursing agency

ARM is 100% publicly owned, trading on the New York Stock Exchange (NYSE). No
one has the direct or indirect power to control ARM, except power he or she may
have by virtue of his or her capacity as a director or executive officer of ARM;
no individual beneficially owns more than 5% of the common shares.

Since 1994, ARM has provided substantially all of the services required to be
performed on behalf of the Separate Account. Total fees paid to ARM by National
Integrity for management services in 1997 were $5,855,216 and in 1998 were
$8,766,003 including services applicable to the Registrant.

National Integrity is the custodian for the shares of the Funds owned by the
Separate Account. The Funds' shares are held in book-entry form.

Reports and marketing materials, from time to time, may include information
concerning the rating of National Integrity, as determined by A.M. Best Company,
Moody's Investor Service, Standard & Poor's Corporation, Duff & Phelps
Corporation, or other recognized rating services. National Integrity is
currently rated "A" (Excellent) by A.M. Best Company, and has received claims
paying ability ratings of "A" (Good) from Standard & Poor's Corporation, "Baa1"
from Moody's Investors Service, Inc., and "A+" (High) from Duff and Phelps
Credit Rating Company. However, National Integrity doesn't guarantee the
investment performance of the portfolios, and these ratings don't reflect
protection against investment risk.

PART 2 - DISTRIBUTION OF THE CONTRACTS

ARM Securities, a wholly owned subsidiary of ARM, is the principal underwriter
of the contracts. ARM Securities is registered with the SEC as a broker-dealer
and is a member in good standing of the National Association of Securities
Dealers, Inc. ARM Securities' address is 515 West Market Street, Louisville,
Kentucky 40202. The contracts are offered through ARM Securities on a continuous
basis.

We generally pay a maximum distribution allowance of 7% of initial and
additional contributions. The amount of distribution allowances paid was
$1,753,582 for the year ended December 31, 1998, $2,647,756 for the year ended
December 31, 1997 and $2,229,269 for the year ended December 31, 1996.
Distribution allowances weren't retained by ARM Securities during these years.
National Integrity may from time to time pay or allow additional promotional
incentives, in the form of cash or other compensation, to broker-dealers that
sell contracts. In some instances, those types of incentives may be offered only
to certain broker-dealers that sell or are expected to sell certain minimum
amounts of the contracts during specified time periods.

PART 3 - PERFORMANCE INFORMATION

Each Variable Account Option may from time to time include the Average Annual
Total Return, the Cumulative Total Return, and Yield of its shares in
advertisements or in information furnished to shareholders. The VIP Money Market
Option may also from time to time include the Yield and Effective Yield of its
shares in information furnished to shareholders. Performance information is
computed separately for each Option in accordance with the formulas described
below. At any time in the future, total return and yields may be higher or lower
than in the past and we can't guarantee that any historical results will
continue.


<PAGE>

TOTAL RETURNS

Total returns reflect all aspects of an Option's return, including the automatic
reinvestment by the Option of all distributions and the deduction of all charges
that apply to the Option on an annual basis, including mortality risk and
expense charges, the annual administrative charge and other charges against
contract values. For purposes of charges not based upon a percentage of contract
values, an average account value of $40,000 has been used. Quotations also will
assume a termination (surrender) at the end of the particular period and reflect
the deductions of the contingent withdrawal charge, if they would apply. Any
total return calculation will be based upon the assumption that the Option
corresponding to the investment portfolio was in existence throughout the stated
period and that the applicable contractual charges and expenses of the Option
during the stated period were equal to those that currently apply under the
contract. Total returns may be shown at the same time that do not take into
account deduction of the contingent withdrawal charge, and/or the annual
administrative charge.

AVERAGE ANNUAL TOTAL RETURNS are calculated by determining the growth or 
decline in value of a hypothetical historical investment in the Option over 
certain periods, including 1, 3, 5, and 10 years (up to the life of the 
Option), and then calculating the annually compounded percentage rate that 
would have produced the same result if the rate of growth or decline in value 
had been constant over the period. Investors should realize that the Option's 
performance is not constant over time, but changes from year to year, and 
that the average annual returns represent the averages of historical figures 
as opposed to the actual historical performance of an Option during any 
portion of the period shown. Average annual returns are calculated pursuant 
to the following formula: P(1+T) TO THE POWER OF n = ERV, where P is a 
hypothetical initial payment of $1,000, T is the average annual total return, 
n is the number of years, and ERV is the withdrawal value at the end of the 
period.

CUMULATIVE TOTAL RETURNS are UNAVERAGED and reflect the simple percentage change
in the value of a hypothetical investment in the Option over a stated period of
time. In addition to the period since inception, cumulative total returns may be
calculated on a year-to-date basis at the end of each calendar month in the
current calendar year. The last day of the period for year-to-date returns is
the last day of the most recent calendar month at the time of publication.

YIELDS

Some Options may advertise yields. Yields quoted in advertising reflect the
change in value of a hypothetical investment in the Option over a stated period
of time, not taking into account capital gains or losses or any contingent
withdrawal charge. Yields are annualized and stated as a percentage.

CURRENT YIELD AND EFFECTIVE YIELD are calculated for the VIP Money Market
Option. Current Yield is based on the change in the value of a hypothetical
investment (exclusive of capital changes) over a particular 7-day period, less a
hypothetical charge reflecting deductions from contract values during the period
(THE BASE PERIOD), and stated as a percentage of the investment at the start of
the base period (THE BASE PERIOD RETURN). The base period return is then
annualized by multiplying by 365/7, with the resulting yield figure carried to
at least the nearest hundredth of one percent. Effective yield assumes that all
dividends received during an annual period have been reinvested. This
compounding effect causes effective yield to be higher than current yield.
Calculation of effective yield begins with the same base period return used in
the calculation of current yield, which is then annualized to reflect weekly
compounding pursuant to the following formula: Effective Yield = {(Base Period
Return) + 1) TO THE POWER OF 365/7} - 1

(1)  Standard average annual return reflects past fund performance based on a
     $1,000 hypothetical investment period over the indicated. The performance
     figures reflect the deduction of mortality and expenses and administrative
     charges totaling 1.35%. They also reflect any withdrawal charges that would
     apply if an owner terminated the policy at the end of the period, but
     exclude deductions for the applicable premium tax charges. Surrender
     charges are 8% in year one, declining 1% annually in years one through
     seven, 0% thereafter.
(2)  Inception date of the variable account option represents first trade date.
     Returns for accounts in operation for less than one year are not
     annualized.
(3)  Non-standard returns reflect all historical investment results, less
     mortality and expense and administrative charges totaling 1.35%. The
     calculation assumes the policy is still in force and therefore does not
     take withdrawal charges into consideration.
(4)  Italicized returns are calculated from the inception date through year-end.
(5)  Represents the inception date of the underlying funds. Performance data for
     periods prior to the actual inception of the variable account options is
     hypothetical and based on the performance of the underlying funds. This
     performance data has been adjusted to include all insurance company
     contract charges and management fees of the underlying funds.

PERFORMANCE COMPARISONS

Performance information for an Option may be compared, in reports and
advertising, to: (1) Standard & Poor's Stock Index (S&P 500), Dow Jones
Industrial Averages, (DJIA), Donoghue Money Market Institutional Averages, or
other unmanaged indices generally regarded as representative of the securities
markets; (2) other variable annuity separate accounts or other investment
products tracked by Lipper Analytical Services, Inc. or the Variable Annuity
Research and Data Service, which are widely used independent research firms that
rank mutual funds and other investment companies by overall performance,
investment objectives, and assets; and (3) the Consumer Price Index (measure of
inflation) to assess the real rate of return from an investment in a contract.
Unmanaged indices may assume the reinvestment of dividends but generally do not
reflect deductions for annuity charges, investment management costs, brokerage
costs and other transaction costs that are normally paid when directly investing
in securities.

Each Option may from time to time also include the ranking of its performance
figures relative to such figures for groups of mutual funds categorized by
Lipper Analytical Services (LIPPER) as having the same or similar investment
objectives or by similar services that monitor the performance of mutual funds.
Each Option may also from time to time compare its performance to average mutual
fund performance figures compiled by Lipper in LIPPER PERFORMANCE ANALYSIS.
Advertisements or information furnished to present shareholders or prospective
investors may also include evaluations of an Option published by nationally
recognized ranking services and by financial publications that are nationally
recognized such as BARRON'S, BUSINESS WEEK, CDA TECHNOLOGIES, INC., CHANGING
TIMES, CONSUMER'S DIGEST, DOW JONES INDUSTRIAL AVERAGE, FINANCIAL PLANNING,
FINANCIAL TIMES, FINANCIAL WORLD, FORBES, FORTUNE, GLOBAL INVESTOR, HULBERT'S
FINANCIAL DIGEST, INSTITUTIONAL INVESTOR, INVESTORS DAILY, MONEY, MORNINGSTAR
MUTUAL FUNDS, THE NEW YORK TIMES, PERSONAL INVESTOR, STANGER'S INVESTMENT
ADVISER, VALUE LINE, THE WALL STREET JOURNAL, WIESENBERGER INVESTMENT COMPANY
SERVICE AND USA TODAY.

The performance figures described above may also be used to compare the
performance of an Option's shares against certain widely recognized standards or
indices for stock and bond market performance. The following are the indices
against which the Options may compare performance:

The Standard & Poor's Composite Index of 500 Stocks (the S&P 500) is a market
value-weighted and unmanaged index showing the changes in the aggregate market
value of 500 stocks relative to the base period 1941-43. The S&P 500 Index is
composed almost entirely of common stocks of companies listed on the NYSE,
although the common stocks of a few companies listed on the American Stock
Exchange or traded OTC are included. The 500 companies represented include 400
industrial, 60 transportation and 50 financial services concerns. The S&P 500
Index represents about 80% of the market value of all issues traded on the NYSE.

service.

PART 4 - DETERMINATION OF ANNUITY UNIT VALUES

The annuity unit value was initially fixed at $1.00 for contracts with assumed
base rates of net investment return of 5% and 3.5% a year, respectively. For
each valuation period thereafter, it is the annuity value for the preceding
valuation period multiplied by the adjusted net investment factor under the
contracts. For each valuation period, the adjusted net investment factor is
equal to the net investment factor reduced for each day in the valuation period
by:

  -    .00013366 for a contract with an assumed base rate of net investment
       return of 5% a year; or

  -    .00009425 for a contract with an assumed base rate of net investment
       return of 3.5% a year.

Because of this adjustment, the annuity unit value rises and falls depending on
whether the actual rate of net investment return (after charges) is higher or
lower than the assumed base rate.

All certificates have a 5% assumed base rate, except in states where that rate
is not permitted. Annuity payments under contracts with an assumed base rate of
3.5% will at first be smaller than those under contracts with a 5% assumed base
rate. Payments under the 3.5% contracts, however, will rise more rapidly when
unit values are rising, and payments will fall more slowly when unit values are
falling, than those under 5% contracts.

The amounts of variable annuity payments are determined as follows:

Payments normally start on the Annuitant's retirement date. The first three
monthly payments are the same and will be based on the amount taken from the
tables in the contract or on our current rates, whichever is more favorable to
the participant. Where the Company's current annuity rates are used,
contributions in the current and five prior participation years will qualify for
the Company's current individual annuity rates applicable to funds derived from
sources outside the Company. The balance of the proceeds will qualify for the
Company's current individual annuity rates for payment of proceeds.

The first three monthly payments depend on the assumed base rate of net
investment return and the forms of annuity chosen (and any fixed period). If the
annuity involves a life contingency, the risk class and the age of the
annuitants will affect payments.


<PAGE>

Payments after the first three months will vary according to the investment
performance of the Variable Account Option or Options selected. After that, each
payment will be calculated by multiplying the number of annuity units credited
by the average annuity unit value for the second calendar month before the due
date of the payment. The number of annuity units credited equals the initial
periodic payment divided by the annuity unit value for the valuation period that
includes the due date of the first annuity payment. The average annuity unit
value is the average of the annuity unit values for the valuation periods ending
in that month. Each business day is considered a valuation period. Days that
aren't considered business days are added to the next business day and
constitute one valuation period. For example, Saturday, Sunday and Monday are
considered to be one valuation period.

ILLUSTRATION OF CHANGES IN ANNUITY UNIT VALUES. To show how we determine
variable annuity payments from month to month, assume that the contract value on
a retirement date is enough to fund an annuity with a monthly payment of $363
and that the annuity unit value for the valuation period that includes the due
date of the first annuity payment is $1.05. The number of annuity units credited
under your contract would be 345.71 (363 divided by 1.05 = 345.71).

If the fourth monthly payment is due in March, and the average annuity unit
value for January was $1.10, the annuity payment for March would be the number
of units (345.71) times the average annuity unit value ($1.10), or $380.28. If
the average annuity unit value was $1.00 in February, the annuity payment for
April would be 345.71 times $1.00, or $345.71.

For period certain life annuities and life income annuities, the participant may
not surrender or redeem once annuity payments begin. For period certain life
annuities only, if the payee (or the payee and the other annuitant under a joint
and survivor annuity) dies before the period selected ends, the remaining
payments will go to another named payee who may have the right to redeem the
annuity and get the cash value of future guaranteed payments in a lump sum. The
present value of future guaranteed payments for a period certain is based on the
number of payments left, the assumed base rate of net return, the number of
annuity units and the annuity unit value for the date the Company receives a
written request for lump sum payment of remaining values. Assets held in the
Account at least equal to all statutory reserves required for such Separate
Account.

PART 5 - TAX FAVORED RETIREMENT PROGRAMS

The contracts described in the prospectus may be used in connection with certain
tax-favored retirement programs, for groups and individuals. Following are brief
descriptions of various types of qualified plans in connection with which
National Integrity may issue a contract. National Integrity reserves the right
to change its administrative rules, such as minimum contribution amounts, as
needed to comply with the Code as to tax-favored retirement programs.

TRADITIONAL INDIVIDUAL RETIREMENT ANNUITIES

Code Section 408(b) permits eligible individuals to contribute to an individual
retirement program known as a Traditional IRA. An individual who receives
compensation and who has not reached age 70-1/2 by the end of the tax year may
establish a Traditional IRA and make contributions up to the deadline for filing
his or her federal income tax return for that year (without extensions).
Traditional IRAs are subject to limitations on the amount that may be
contributed, the persons who may be eligible, and on the time when distributions
may begin. An individual may also rollover amounts distributed from another
Traditional IRA, Roth IRA or another tax-favored retirement program to a
Traditional IRA contract. Your Traditional IRA contract will be issued with a
rider outlining the special terms of your contract that apply to Traditional
IRAs. The Owner will be deemed to have consented to any other amendment unless
the Owner notifies us that he or she does not consent within 30 days from the
date we mail the amendment to the Owner.

ROTH INDIVIDUAL RETIREMENT ANNUITIES

Section 408(A) of the Code permits eligible individuals to contribute to an
individual retirement program known as a Roth IRA. An individual who receives
compensation may establish a Roth IRA and make contributions up to the deadline
for filing his or her federal income tax return for that year (without
extensions). Roth IRAs are subject to limitations on the amount that may be
contributed, the persons who are eligible to contribute, and on the time when a
tax-favored distribution may begin. An individual may also rollover amounts
distributed from another Roth IRA or Traditional IRA to a Roth IRA contract.
Your Roth IRA contract will be issued with a rider outlining the


<PAGE>

special terms of your contract which apply to Roth IRAs. Any amendment made for
the purpose of complying with provisions of the Code and related regulations may
be made without the consent of the Owner. The Owner will be deemed to have
consented to any other amendment unless the Owner notifies us that he or she
does not consent within 30 days from the date we mail the amendment to the
Owner.

SIMPLE INDIVIDUAL RETIREMENT ANNUITIES

Currently, we do not issue Individual Retirement Annuities known as a "SIMPLE
IRA" as defined in Section 408(p) of the Code.

TAX SHELTERED ANNUITIES

Section 403(b) of the Code permits the purchase of tax-sheltered annuities (TSA)
by public schools and certain charitable, educational and scientific
organizations described in Section 501(c)(3) of the Code. The contract is not
intended to accept other than employee contributions. Such contributions are
excluded from the gross income of the employee until the employee receives
distributions from the contract. The amount of contributions to the TSA is
limited to certain maximums imposed by Code sections 403(b), 415 and 402(g).
Furthermore, the Code sets forth additional restrictions governing such items as
transferability, distributions and withdrawals. Any employee should obtain
competent tax advice as to the tax treatment and suitability of such an
investment. Your contract will be issued with a rider outlining the special
terms that apply to a TSA.

SIMPLIFIED EMPLOYEE PENSIONS

Section 408(k) of the Code allows employers to establish simplified employee
pension plans (SEP-IRAs) for their employees, using the employees' IRAs for such
purposes, if certain criteria are met. Under these plans the employer may,
within specified limits, make deductible contributions on behalf of the
employees to IRAs. Employers intending to use the contract in connection with
such plans should seek competent advice. The SEP-IRA will be issued with a rider
outlining the special terms of the contract.

CORPORATE AND SELF-EMPLOYED (H.R. 10 AND KEOGH) PENSION AND PROFIT SHARING PLANS

Sections 401(a) and 403(a) of the Code permit corporate employers to establish
various types of tax-favored retirement plans for employees. The Self-Employed
Individuals' Tax Retirement Act of 1962, as amended, commonly referred to as
"H.R. 10" or "Keogh," permits self-employed individuals also to establish such
tax-favored retirement plans for themselves and their employees. Such retirement
plans may permit the purchase of the contract in order to provide benefits under
the plans. Employers intending to use the contract in connection with these
plans should seek competent advice. The Company can request documentation to
substantiate that a qualified plan exists and is being properly administered.
National Integrity does not administer such plans.

DEFERRED COMPENSATION PLANS OF STATE AND LOCAL GOVERNMENTS AND TAX-EXEMPT
ORGANIZATIONS

Section 457 of the Code permits employees of state and local governments and
tax-exempt organizations to defer a portion of their compensation without paying
current taxes. The employees must be participants in an eligible deferred
compensation plan. To the extent the contracts are used in connection with an
eligible plan, employees are considered general creditors of the employer and
the employer as Owner of the contract has the sole right to the proceeds of the
contract. However, Section 457(g), as added by the Small Business and Jobs
Protection Act (SBJPA) of 1996, provides that on and after August 20, 1996, a
plan maintained by an eligible governmental employer must hold all assets and
income of the plan in a trust, custodial account, or annuity contract for the
exclusive benefit of participants and their beneficiaries. Plans in existence on
August 20, 1996, should have established a trust, custodial account, or annuity
contract by January 1, 1999. Loans to employees may be permitted under such
plans; however, a Section 457 plan is not required to allow loans. Contributions
to a contract in connection with an eligible government plan are subject to
limitations. Those who intend to use the contracts in connection with such plans
should seek competent advice. The Company can request documentation to
substantiate that a qualified plan exists and is being properly administered.
National Integrity does not administer such plans.


<PAGE>

DISTRIBUTIONS UNDER TAX FAVORED RETIREMENT PROGRAMS

Distributions from tax-favored plans are subject to certain restrictions. Prior
to the enactment of the 1996 SBJPA, distributions of minimum amounts specified
by the Code must have commenced by April 1 of the calendar year following the
calendar year in which the participant reaches age 70-1/2. The SBJPA provides
participants in qualified plans, with the exception of five-percent owners and
Traditional IRA holders, to begin receiving distributions by April 1 of the
calendar year following the later of either (i) the calendar year in which the
employee reaches age 70-1/2, or (ii) the calendar year in which the employee
retires. Additional distribution rules apply after the participant's death.
Failure to make mandatory distributions may result in the imposition of a 50%
penalty tax on any difference between the required distribution amount and the
amount distributed. Distributions to a participant from all plans (other than
457 plans) in a calendar year that exceed a specific limit under the Code are
generally subject to a 15% penalty tax (in addition to any ordinary income tax)
on the excess portion of the distributions. However, the SBJPA of 1996 has
suspended the excise tax on excess distributions. The provision relating to the
excise tax on excess distributions is effective with respect to distributions
received in 1997, 1998 and 1999.

The Taxpayer Relief Act of 1997 creating Roth IRAs eliminates mandatory
distribution at age 70 1/2 for Roth IRAs.

Distributions from a tax-favored plan (not including a Traditional IRA subject
to Code Section 408(a) Roth IRA) to an employee, surviving spouse, or former
spouse who is an alternate payee under a qualified domestic relations order, in
the form of a lump sum settlement or periodic annuity payments for a fixed
period of fewer than 10 years are subject to mandatory income tax withholding of
20% of the taxable amount of the distribution, unless (1) the distributee
directs the transfer of such amounts in cash to another plan or Traditional IRA;
or (2) the payment is a minimum distribution required under the Code. The
taxable amount is the amount of the distribution less the amount allocable to
after-tax contributions. All other types of taxable distributions are subject to
withholding unless the distributee elects not to have withholding apply.

We are not permitted to make distributions from a contract unless a request has
been made. It is therefore your responsibility to comply with the minimum
distribution rules. You should consult your tax adviser regarding these rules
and their proper application.

The above description of the federal income tax consequences of the different
types of tax-favored retirement plans which may be funded by the contract is
only a brief summary and is not intended as tax advice. The rules governing the
provisions of plans are extremely complex and often difficult to comprehend.
Anything less than full compliance with all applicable rules, all of which are
subject to change, may have adverse tax consequences. A prospective Owner
considering adoption of a plan and purchase of a contract in connection
therewith should first consult a qualified and competent tax adviser, with
regard to the suitability of the contract as an investment vehicle for the plan.

THIS PROSPECTUS DOES NOT CONSTITUTE AN OFFERING IN ANY JURISDICTION IN WHICH
SUCH OFFERING MAY NOT LAWFULLY BE MADE. NO PERSON IS AUTHORIZED TO MAKE ANY
REPRESENTATIONS IN CONNECTION WITH THIS OFFERING OTHER THAN THOSE CONTAINED IN
THIS PROSPECTUS.
    

   
PART 1 - SUMMARY
    
   
YOUR VARIABLE ANNUITY CONTRACT
    
   
In this prospectus, "WE," "OUR" and "US" mean National Integrity Life Insurance
Company (NATIONAL INTEGRITY), a subsidiary of Integrity Life Insurance Company
and an indirect subsidiary of ARM Financial Group, Inc. (ARM). The terms "YOU"
and "YOUR" mean the Annuitant, the person upon whose life the Annuity Benefit
and the Death Benefit are
    


                                       4
<PAGE>

   
based, usually the Owner of the contract. If the Annuitant doesn't own the
contract, all of the rights under the contract belong to the Owner until annuity
payments begin. If a Joint Owner is named, the owners share contract rights.
Contract changes or any transactions allowed under the contract require both
Owners' signatures. The rules governing distribution at death apply when the
first Owner dies. See Part 7, "Distribution-at-Death Rules."
    
   
You can invest for retirement by buying an IQ Smart Annuity if you properly
complete a Customer Profile form (an application or enrollment form may be
required in some states) and make a minimum initial contribution. Because the
premium is flexible, your future contributions can be any amount you choose, as
long as it is above the minimum required contribution, discussed below.
    
   
The latest your endowment or "retirement date" can be is your 90th birthday
unless your state law requires it to be a different date, or unless you specify
an earlier date.
    
   
YOUR BENEFITS
    
   
Your contract has an Account Value, an annuity benefit, and a death benefit.
These benefits are described in more detail below.
    
   
Your benefits under a contract may be controlled by the usual rules for taxation
of annuities, including the deferral of taxes on your investment growth until
you actually make a withdrawal. The contract also can provide your benefits
under certain tax-favored retirement programs, which may be subject to special
eligibility and contribution rules. See Part 7, "Tax Aspects of the Contracts"
for detailed information.
    
   
HOW YOUR CONTRACT IS TAXED
    
   
Under the current tax laws, any increases in the value of your contributions
won't be considered part of your taxable income until you make a withdrawal.
    
   
YOUR CONTRIBUTIONS
    
   
Your minimum initial contribution is $1,000. Contributions after your first one
can be as little as $100. Some tax-favored retirement plans allow smaller
contributions. See "Contributions Under Your Contract" in Part 5.
    
   
YOUR INVESTMENT OPTIONS
    
   
You may have your contributions placed in the Variable Account Options or the
GROs, or place part of your contributions in each of them. The Variable Account
Options and the GROs are together referred to as the INVESTMENT OPTIONS. You may
have money in as many as nine Investment Options at any one time. See
"Contributions Under Your Contract" in Part 5. To select Investment Options most
suitable for you, see Part 3, "Your Investment Options."
    
   
The Variable Account Options invest in shares of investment portfolios of mutual
funds. Each investment portfolio is referred to as a PORTFOLIO. The investment
goal of each Variable Account Option and its corresponding Portfolio is the
same. For example, if your investment goal is to save money for retirement, you
might choose a GROWTH oriented Variable Account Option, which invests in GROWTH
Portfolios. Your value in a Variable Account Option will vary with the
performance of the corresponding Portfolio. For a full description of the
Portfolios, see the Portfolios' prospectus and Statement of Additional
Information.
    
   
ACCOUNT VALUE, ADJUSTED ACCOUNT VALUE AND CASH VALUE
    
   
Your ACCOUNT VALUE consists of the value of your GROs added to the value of your
Variable Account Options. Your ADJUSTED ACCOUNT VALUE is your Account Value, as
increased or decreased (but not below the Minimum Value) by any Market Value
Adjustments. Your CASH VALUE is equal to your Adjusted Account Value minus the
pro rata portion of the annual administrative charge, if it applies. See
"Charges and Fees" below.
    
   
TRANSFERS
    


                                       5
<PAGE>

   
You may transfer all or any part of your Account Value among the Investment
Options, although there are some restrictions that apply. You can find these in
Part 5, "Transfers." Any transfer must be for at least $250 and may be arranged
through our telephone transfer service. Transfers may also be made among certain
Investment Options under the following special programs: (i) Dollar Cost
Averaging, (ii) Customized Asset Rebalancing, or (iii) Asset Allocation and
Rebalancing Program. All of these programs are discussed in Part 8. If you make
more than twelve transfers between your Investment Options in one contract year,
your account can be charged up to $20 for each transfer after twelve.
    
   
CHARGES AND FEES
    
   
If your Account Value is less than $50,000 as of the last day of any contract
year before your Retirement Date, an annual administrative expense charge of $30
is deducted from your Account.
    
   
A daily charge at an effective annual rate of 1.45% is deducted from the Account
Value of each of your Variable Account Options to cover mortality and expense
risks (1.30%) and certain administrative expenses (.15%). The charge will never
be greater than this. For more information, see Part 4, "Deductions and
Charges."
    
   
Investment advisory fees and other expenses are deducted from amounts the
Separate Account invests in the Portfolios. Fidelity Management and Research
Company (FIDELITY MANAGEMENT) receives investment management fees from the
Portfolios based on the average net assets of each Portfolio. Advisory fees
can't be increased without the consent of shareholders. See "Table of Annual
Fees and Expenses" below and "The Portfolios' Investment Adviser" in Part 3.
    
   
WITHDRAWALS
    
   
You may make any number of withdrawals from your contract as frequently as you
wish. Each withdrawal must be for at least $300.
    
   
YOUR INITIAL RIGHT TO REVOKE
    
   
You can cancel your contract within ten days after you receive it by returning
it to our Administrative Office. We will extend the ten-day period as required
by law in some states. If you cancel your contract, we'll return your entire
contribution, with adjustments made for any investment gain or loss experienced
by the Variable Account Option from the date you purchased it until the date we
receive your cancelled contract, including any charges deducted. If your state
requires, we'll return all of your contributions without any adjustment. We'll
return the amount of any contribution to the Guaranteed Rate Option upon
cancellation.
    
   
RISK/RETURN SUMMARY: INVESTMENTS AND RISKS
    
   
VARIABLE ANNUITY INVESTMENT GOALS
    
   
The investment goals of the IQ SMARTAnnuity are protecting your investment,
building for retirement and providing future income. We strive to achieve these
goals through extensive portfolio diversification and superior portfolio
management.
    
   
RISKS
    
   
An investment in any of the Variable Account Options carries with it certain
risks, including the risk that the value of your investment will decline and you
could lose money. This could happen if one of the issuers of the stocks becomes
financially impaired or if the stock market as a whole declines. Because most of
the Variable Account Options are in common stocks, there's also the inherent
risk that holders of common stock generally are behind creditors and holders of
preferred stock for payments in the event of the bankruptcy of a stock issuer.
    
   
For a complete discussion of the risks associated with an investment in any
particular Variable Account Option, see the prospectus of the corresponding
Portfolio.
    
   
YEAR 2000
    


                                       6
<PAGE>

   
Many computer programs are written so that only the last two digits of the year
are read. Because of this, many computer systems will read the year 2000 as
1900. This could cause many programs to malfunction. National Integrity is
evaluating, on an ongoing basis, its computer systems and the systems of other
companies on which we rely, to determine if they'll function properly, and make
the transition from 1999 to 2000 smoothly. These activities are designed to
ensure that there is no adverse effect on our business operations. While we've
been working very hard to make sure that this process will be problem-free, we
can't guarantee that there won't be some Year 2000 problems experienced by our
systems and we can't make any representations or guarantees that the outside
sources on which we rely will be ready to make a smooth transition to Year 2000
with their systems.

(1)  After the first twelve transfers during a contract year, we can charge a
     transfer fee of $20 for each transfer. This charge doesn't apply to
     transfers made for dollar cost averaging, asset rebalancing, or systematic
     transfers. See "Deductions and Charges - Transfer Charge" in Part 4.
    
   
(2)  See "Deductions and Charges - Separate Account Charges" in Part 4.
    
   
(3)  The "Other Expenses" reflect the payment of 0.10% pursuant to a Rule 12b-1
     Plan adopted by the underlying Mutual Funds.
    
   
(4)  Part of the brokerage commissions that certain Portfolios pay was used to
     reduce the Portfolios' expenses. In addition, certain Portfolios have
     arranged with their custodian to use uninvested cash balances to reduce
     custodian expenses. Including these reductions, the total operating
     expenses presented in the table would have been .57% for VIP Equity-Income
     Portfolio, .66% for VIP Growth Portfolio, .89% for VIP Overseas Portfolio,
     .63% for VIP II Asset Manager Portfolio, .66% for VIP II Contrafund
     Portfolio, .72% for VIP II Asset Manager: Growth Portfolio, .58% for VIP
     III Balanced Portfolio, .70% for VIP III Growth Opportunities Portfolio,
     and .70% for VIP III Growth and Income Portfolio.
    
   
(5)  The investment adviser agreed to reimburse part of VIP II Index 500
     Portfolio's and VIP III Mid Cap Portfolio's expenses during the period.
     Without this reimbursement, management fees, other expenses and total
     expenses would have been .28%, .11%, and .39%, respectively for VIP II
     Index 500 Portfolio and .56%, 115.40% and 115.96%, respectively, for VIP
     III Mid Cap Portfolio.

EXPENSES PER $1,000 INVESTMENT IF YOU ELECT THE NORMAL FORM OF ANNUITY OR DON'T
SURRENDER YOUR CONTRACT AT THE END OF THE APPLICABLE PERIOD:
    
   
Same expenses per $1,000 investment as shown in table immediately above.
    
   
These examples assume a continuation of the fixed charges that are borne by the
Separate Account and of the investment advisory fees and other expenses of the
Funds as they were for their most recent fiscal year or estimated expenses
(after reimbursement), if applicable. ACTUAL FUND EXPENSES MAY BE GREATER OR
LESS THAN THOSE ON WHICH THESE EXAMPLES WERE BASED. The annual rate of return
assumed in the examples is not an estimate or guarantee of future investment
performance. The table also assumes an estimated $40,000 average contract value,
so that the administrative charge per $1,000 of net asset value in the Separate
Account is $0.75. Such per $1,000 charge would be higher for smaller Account
Values and lower for higher values.
    
   
The above table and examples are intended to assist your understanding of the
various costs and expenses that apply to your contract, directly or indirectly.
These tables reflect expenses of the Separate Account as well as those of the
Portfolios. Premium taxes upon annuitization also may be applicable.

THE SEPARATE ACCOUNT AND THE VARIABLE ACCOUNT OPTIONS
    

   
The Separate Account is established and maintained under the insurance laws of
the State of New York. It is a unit investment trust registered with the
Securities and Exchange Commission (the SEC) under the Investment Company Act of
1940 (1940 ACT). A unit investment trust is a type of investment company. SEC
registration doesn't mean that the SEC is involved in any way in supervising the
management or investment policies of the Separate Account. Each Variable Account
Option invests in shares of a corresponding Portfolio. We may establish
additional Options from time to time. The Variable Account Options currently
available to you are listed in Part 3, "Your Investment Options." Prior to
September 3, 1991, the Portfolios then offered invested in shares of
corresponding portfolios of Prism Investment Trust.
    

   
ASSETS OF OUR SEPARATE ACCOUNT
    

   
Under New York law, we own the assets of our Separate Account and use them to
support the variable portion of yours and other variable annuity contracts.
Annuitants under other variable annuity contracts participate in the Separate
Account in proportion to the amounts in their contracts. We can't use the
Separate Account's assets supporting the variable portion of these variable
contracts to satisfy liabilities arising out of any of our other businesses.
Under certain unlikely circumstances, one Variable Account Option may be liable
for claims relating to the operations of another Option.
    

   
Income, gains and losses, whether or not realized, from assets allocated to the
Separate Account are credited to or charged against the Separate Account without
regard to our other income, gains or losses. We may allow charges owed to us to
stay in the Separate Account, and in that way, we can participate
proportionately in the Separate Account. Amounts in the Separate Account in
excess of reserves and other liabilities belong to us, and we may transfer them
to our general account.
    

   
CHANGES IN HOW WE OPERATE
    

   
We can change how we or our Separate Account operate, subject to your approval
when required by the 1940 Act or other applicable law or regulation. We'll
notify you if any changes result in a material change in the underlying
investments of a Variable Account Option. WE MAY:
    

   
- -    add Options to, or remove Options from, our Separate Account, combine two
     or more Options within our Separate Account, or withdraw assets relating to
     your contract from one Option and put them into another;
- -    register or end the registration of the Separate Account under the 1940
     Act;
- -    operate our Separate Account under the direction of a committee or
     discharge a committee at any time (the committee may be composed of a
     majority of persons who are "interested persons" of National Integrity
     under the 1940 Act);
- -    restrict or eliminate any voting rights of Owners or others who have voting
     rights that affect our Separate Account;
- -    cause one or more Options to invest in a mutual fund other than or in
     addition to the Portfolios; - operate our Separate Account or one or more
     of the Options in any other form the law allows, including a form that
     allows us to make direct investments. We may make any legal investments we
     wish. In choosing these investments, we'll rely on our own or outside
     counsel for advice.

THE PORTFOLIOS
    

   
Management fees and other expenses deducted from each Portfolio are described in
that Portfolio's prospectus. FOR A PROSPECTUS CONTAINING MORE COMPLETE
INFORMATION ON ANY PORTFOLIO, CALL OUR ADMINISTRATIVE OFFICE
TOLL-FREE AT 1-800-433-1778.
    

   
Each of the Portfolios is an open-end diversified management investment company
registered with the SEC.
    

   
The Portfolios serve as investment vehicles for variable annuity and variable
life contracts of insurance companies. Shares of the Portfolios currently are
available to the separate accounts of a number of insurance companies, both
affiliated and unaffiliated with Fidelity Management or Integrity. The Board of
Trustees of each of the Portfolios is responsible for monitoring the Fund for
any material irreconcilable conflict between the interests of the policyowners
of all separate accounts investing in the Portfolio and determining what action,
if any, should be taken in response. If we believe that a Portfolio's response
to any of those events doesn't adequately protect our contract owners, we'll see
to it that appropriate and available action is taken. See "The Fund and the
Fidelity Organization" in the Portfolios' prospectus for a further discussion of
the risks associated with the offering of shares to our Separate Account and the
separate accounts of other insurance companies.
    

   
THE PORTFOLIOS' INVESTMENT ADVISER. Fidelity Management & Research Company
(FIDELITY MANAGEMENT) is a registered investment adviser under the Investment
Advisers Act of 1940. It serves as the investment adviser to each Portfolio.
Bankers Trust Company ("BT") is the VIP II Index 500 Portfolio's sub-adviser.

Trust New York Corporation.
    

   
INVESTMENT OBJECTIVES OF THE PORTFOLIOS. Below is a summary of the investment
objectives of the Portfolios of Fidelity's VIP Funds. There are no guarantees
that a Portfolio will be able to achieve its objective. YOU SHOULD READ
FIDELITY'S VIP FUNDS' PROSPECTUS CAREFULLY BEFORE INVESTING.
    

   
                           VIP MONEY MARKET PORTFOLIO
    

   
VIP Money Market Portfolio seeks to earn a high level of current income while
preserving capital and providing liquidity. It invests only in high-quality,
U.S. dollar denominated money market securities of domestic and foreign issuers,
such as certificates of deposit, obligations of governments and their agencies,
and commercial paper and notes.
    

   
                            VIP HIGH INCOME PORTFOLIO
    

   
VIP High Income Portfolio seeks a high current income by investing primarily in
high-yielding, lower rated, fixed-income securities, while also considering
growth of capital. It normally invests at least 65% of its total assets in
income-producing debt securities and preferred stocks, including convertible
securities, and up to 20% in common stocks and other equity securities. In view
of the types of securities in which this Portfolio invests, you should read the
complete risk disclosure for this Portfolio in its prospectus before investing
in it.
    

   
                           VIP EQUITY-INCOME PORTFOLIO
    

   
VIP Equity-Income Portfolio seeks reasonable income. The Portfolio will also
consider the potential for capital appreciation. The Portfolio seeks a yield
which exceeds the composite yield on the securities comprising the S&P 500. FMR
normally invests at least 65% of the Portfolio's total assets in
income-producing equity securities.
    

   
                              VIP GROWTH PORTFOLIO
    

   
VIP Growth Portfolio seeks capital appreciation. FMR invests the Portfolio's
assets in companies FMR believes have above-average growth potential. Growth may
be measured by factors such as earnings or revenue. Companies with high growth
potential tend to be companies with higher than average price/earnings (P/E)
ratios. Companies with strong growth potential often have new products,
technologies, distribution channels or other opportunities for have a strong
industry market position. The stocks of these companies are often called
"growth" stocks.
    

<PAGE>

   
                             VIP OVERSEAS PORTFOLIO
    

   
VIP Overseas Portfolio seeks long-term growth of capital primarily through
investments in foreign securities. It normally invests at least 65% of its
assets in foreign securities.
    
   
                     VIP II INVESTMENT GRADE BOND PORTFOLIO
    

   
VIP II Investment Grade Bond Portfolio seeks as high a level of current income
while preserving capital by investing in a broad range of investment-grade
fixed-income securities.
    

   
                         VIP II ASSET MANAGER PORTFOLIO
    

   
VIP II Asset Manager Portfolio seeks high total return with reduced risk over
the long-term by allocating its assets among stocks, bonds and short-term money
market instruments.
    

   
                           VIP II INDEX 500 PORTFOLIO
    

   
VIP II Index 500 Portfolio seeks to provide investment results that correspond
to the total return (i.e., the combination of capital changes and income) of
common stocks publicly traded in the United States. In seeking this objective,
the Portfolio attempts to duplicate the composition and total return of the
Standard & Poor's 500 Composite Stock Price Index while keeping transaction
costs and other expenses low.
    

   
                           VIP II CONTRAFUND PORTFOLIO
    

   
VIP II Contrafund Portfolio seeks long-term capital appreciation. FMR normally
invests the Portfolio's assets primarily in common stocks. FMR invests the
Portfolio's assets in securities of companies whose value FMR believes is not
fully recognized by the public. The types of companies in which the Portfolio
may invest include companies experiencing positive fundamental change such as a
new management team or product launch, a significant cost-cutting initiative, a
merger or acquisition, or a reduction in industry capacity that should lead to
improved pricing; companies whose earning potential has increased or is expected
to increase more than generally perceived; companies that have enjoyed recent
market popularity but which appear to have temporarily fallen out of favor for
reasons that are considered non-recurring or short-term; and companies that are
undervalued in relation to securities of other companies in the same industry.
    

   
                     VIP II ASSET MANAGER: GROWTH PORTFOLIO
    

   
VIP II Asset Manager: Growth Portfolio is an asset allocation fund that seeks to
maximize total return over the long term through investments in stocks, bonds,
and short-term money market instruments. The fund has a neutral mix, which
represents the way the fund's investments will generally be allocated over the
long term. The range and approximate neutral mix for each asset class are shown
below:

                     VIP III GROWTH OPPORTUNITIES PORTFOLIO
    

   
VIP III Growth Opportunities Portfolio seeks to provide capital growth. FMR
normally invests the Portfolio's assets primarily in common stocks. FMR may also
invest the Portfolio's assets in other types of securities, including bonds,
which may be lower-quality debt securities.
    

<PAGE>

   
                           VIP III BALANCED PORTFOLIO
    

   
VIP III Balanced Portfolio seeks both income and growth of capital by investing
in a diversified portfolio of equity and fixed-income securities. It uses a
balanced approach to provide the best possible total return from investments in
foreign and domestic equity securities, convertible securities, preferred and
common stocks paying any combination of dividends and capital gains, and fixed
income securities.
    

   
                        VIP III GROWTH & INCOME PORTFOLIO
    

   
VIP III Growth & Income Portfolio seeks high total return through a combination
of current income and capital appreciation. FMR normally invests a majority of
the Portfolio's assets in common stocks with a focus on those that pay current
dividends and show potential for capital appreciation. FMR may also invest the
Portfolio's assets in bonds, including lower-quality debt securities, as well as
stocks that are not currently paying dividends, but offer prospects for future
income or capital appreciation.
    

   
                            VIP III MID CAP PORTFOLIO
    

   
FMR normally invests the VIP III Mid Cap Portfolio's assets primarily in common
stocks. FMR normally invests at least 65% of the Portfolio's total assets in
securities of companies with medium market capitalizations. Medium market
capitalization companies are those whose market capitalization is similar to the
capitalization of companies in the S&P Mid Cap 400 at the time of the
investment. Companies whose capitalization no longer meets this definition after
purchase continue to be considered to have a medium market capitalization for
purposes of the 65% policy.

GUARANTEED RATE OPTION
    

   
FOR VARIOUS LEGAL REASONS, INTERESTS IN CONTRACTS ATTRIBUTABLE TO GROS HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 ("1933 ACT"), NOR UNDER THE
INVESTMENT COMPANY ACT OF 1940 ("1940 ACT"). THUS, NEITHER THESE CONTRACTS NOR
OUR GENERAL ACCOUNT, WHICH GUARANTEES THE VALUES AND BENEFITS UNDER THOSE
CONTRACTS, ARE GENERALLY SUBJECT TO REGULATION UNDER THE PROVISIONS OF THE 1933
ACT OR THE 1940 ACT. ACCORDINGLY, WE HAVE BEEN ADVISED THAT THE STAFF OF THE
SECURITIES AND EXCHANGE COMMISSION HASN'T REVIEWED THE DISCLOSURE IN THIS
PROSPECTUS RELATING TO THE GROS OR THE GENERAL ACCOUNT. DISCLOSURES REGARDING
THE GROS OR THE GENERAL ACCOUNT MAY, HOWEVER, BE SUBJECT TO CERTAIN GENERALLY
APPLICABLE PROVISIONS OF THE FEDERAL SECURITIES LAWS RELATING TO THE ACCURACY
AND COMPLETENESS OF STATEMENTS MADE IN PROSPECTUSES.
    

   
We offer GROs with durations of three, five, seven and ten years. We can change
the durations available from time to time. When you put money in a GRO, that
locks in a fixed effective annual interest rate that we declare (GUARANTEED
INTEREST RATE) for the duration you select (your GRO ACCOUNT). The duration of
your GRO Account is the GUARANTEE PERIOD. Each contribution or transfer to a GRO
establishes a new GRO Account for the duration you choose at the then-current
Guaranteed Interest Rate we declare. We won't declare an interest rate less than
3%. Each GRO Account expires at the end of the duration you have selected. See
"Renewals of GRO Accounts" below. All contributions you make to a GRO are placed
in a non-unitized separate account. Values and benefits under your contract
attributable to GROs are guaranteed by the reserves in our GRO separate account
as well as by our General Account.
    

   
The value of each of your GRO Accounts is referred to as a GRO VALUE. The GRO
Value at the expiration of the GRO Account, assuming you haven't transferred or
withdrawn any amounts, will be the amount you put in plus interest at the
Guaranteed Interest Rate. We credit interest daily at an effective annual rate
equal to the Guaranteed Interest Rate. We allocate interest at the end of each
contract year and at the time of any transfer, full or partial withdrawal,
payment of a death benefit or purchase of any annuity benefit.
    

   
We may declare a higher rate of interest in the first year for any Contribution
allocated to a GRO that exceeds the Guaranteed Interest Rate credited during the
remaining years of the Guarantee Period (ENHANCED Rate). This Enhanced Rate will
be guaranteed for the Guaranteed Period's first year and declared at the time of
purchase. We can declare and credit additional interest based on Contribution,
Account Value, withdrawal dates, economic conditions or on any other lawful,
nondiscriminatory basis (ADDITIONAL INTEREST). Any Enhanced Rate and Additional
Interest credited to your GRO Account will be separate from the Guaranteed
Interest Rate and not used in the Market Value Adjustment formula. THE ENHANCED
RATE OR ADDITIONAL INTEREST MAY NOT BE MADE APPLICABLE UNDER CONTRACTS ISSUED IN
CERTAIN STATES.
    

   
Each group of GRO Accounts of the same duration is considered one GRO. For
example, all of your three-year GRO Accounts are one GRO while all of your
five-year GRO Accounts are another GRO.
    

   
You can get our current Guaranteed Interest Rates by calling our Administrative
Office.
    

   
ALLOCATIONS TO GROS MAY NOT BE MADE UNDER CONTRACTS ISSUED IN CERTAIN STATES.
    

   
RENEWALS OF GRO ACCOUNTS. When a GRO Account expires, we'll set up a new GRO
Account for the same duration as your old one, at the then-current Guaranteed
Interest Rate, unless you withdraw your GRO Value or transfer it to another
Investment Option. We'll notify you in writing before your GRO Account expires.
You must tell us before the expiration of your GRO Accounts if you want to make
any changes.
    

   
The effective date of a renewal of a GRO Account will be the expiration date of
the old GRO Account. You will receive the Guaranteed Interest Rate that is in
effect on that date. If a GRO Account expires and it can't be renewed for the
same duration, the new GRO Account will be set up for the next shortest
available duration. For example, if your expiring GRO Account was for 10 years
and when it expires, we don't offer a 10-year GRO, but we do offer a seven-year
GRO, your new one will be for seven years. You can tell us if you want something
different within 30 days before the GRO Account expires. You can't choose, and
we won't renew a GRO Account that expires after your Retirement Date.
    

   
MARKET VALUE ADJUSTMENTS. A MARKET VALUE ADJUSTMENT is an adjustment, either up
or down, that we make to your GRO Value if you make an early withdrawal or
transfer from your GRO Account. A Market Value Adjustment will be made for each
transaction made from a GRO Account other than your free withdrawals or those
made within 30 days before the expiration of the Account. There will be no
Market Value Adjustment made for a death benefit. The market adjusted value 
    

<PAGE>

   
may be higher or lower than the GRO Value, but will never be less than the
MINIMUM VALUE. Minimum Value is an amount equal to your allocation to such GRO
Account plus 3% interest, compounded annually, less previous withdrawals from
such GRO Account. The Minimum Value for partial withdrawals or transfers will be
calculated on a pro-rata basis. The administrative expense charge could take
away part of your principal.
    

   
The Market Value Adjustment we make to your GRO Account is based on the changes
in our Guaranteed Interest Rate. If our Guaranteed Interest Rate has increased
since the time of your investment, the Market Value Adjustment will reduce your
GRO Value (but not below the Minimum Value). On the other hand, if our
Guaranteed Interest Rate has decreased since the time of your investment, the
Market Value Adjustment will increase your GRO Value.
    

   
The Market Value Adjustment (MVA) for a GRO Account is determined under the
following formula:
    

   
                               N/12                 N/12
     MVA = GRO Value x [(1 + A)     / (1 + B + .0025)    - 1], where
    

   
     A is the Guaranteed Interest Rate being credited to the GRO Account subject
     to the Market Value Adjustment,
    

   
     B is the current Guaranteed Interest Rate, as of the effective date of the
     application of the Market Value Adjustment, for current allocations to a
     GRO Account, the length of which is equal to the number of whole months
     remaining in your GRO Account. Subject to certain adjustments, if that
     remaining period isn't equal to an exact period for which we have declared
     a new Guaranteed Interest Rate, B will be determined by a formula that
     finds a value between the Guaranteed Interest Rates for GRO Accounts of the
     next highest and next lowest durations.
    

   
     N is the number of whole months remaining in your GRO Account.
    

   
For contracts issued in certain states, the formula above will be adjusted to
comply with applicable state requirements.
    

   
If the remaining term of your GRO Account is 30 days or less, the Market Value
Adjustment for your GRO Account shall be zero. If for any reason we are no
longer declaring current Guaranteed Interest Rates, then for purposes of
determining B we will use the yield to maturity of United States Treasury Notes
with the same remaining term as your GRO Account, using a formula when
necessary, in place of the current Guaranteed Interest Rate or Rates.
    

   
For illustrations of the application of the Market Value Adjustment formula, see
Appendix A.
    

   
PART 4 - DEDUCTIONS AND CHARGES
    

   
SEPARATE ACCOUNT CHARGES
    

   
National Integrity deducts from the unit value every calendar day an amount
equal to an effective annual rate of 1.45% of the Account Value in the Variable
Account Options. This daily expense rate can't be increased without your
consent. Various portions of this total charge, as described below, pay for
certain services to the Separate Account and the contracts.
    

   
Of the 1.45% total charge, .15% of the value of each Variable Account Option is
used to reimburse us for administrative expenses not covered by the annual
administrative charge described below. The remaining 1.30% is deducted for
National Integrity's assuming the expense risk (.95%) and the mortality risk
(.35%) under the contract. The expense risk is the risk that our actual expenses
of administering the contracts will exceed the annual administrative expense
charge. Mortality risk, as used here, refers to the risk National Integrity
takes that annuitants, as a class of persons, will live longer than estimated
and therefore require National Integrity to pay out more annuity benefits than
anticipated. The relative proportion of the mortality and expense risk charges
may be modified, but the total 1.30% effective annual risk charge can't be
increased on your Contract.
    

   
National Integrity may realize a gain from these daily charges if they aren't
needed to meet the actual expenses incurred.
    

   
ANNUAL ADMINISTRATIVE CHARGE
    

   
If your Account Value is less than $50,000 on the last day of any contract year
before your Retirement Date, National Integrity charges an annual administrative
charge of $30. This charge is deducted pro-rata from your Account Value in each
Investment Option. The part of the charge deducted from the Variable Account
Options will reduce the number of units credited to you. The part of the charge
deducted from the GROs is withdrawn in dollars. The annual administrative 
    

<PAGE>

   
charge will be pro-rated in the event of the Annuitant's retirement, death, or
termination of a contract during a contract year.
    

   
REDUCTION OR ELIMINATION OF SEPARATE ACCOUNT OR ADMINISTRATIVE CHARGES
    

   
We can reduce or eliminate the separate account or administrative charges for
individuals or groups of individuals if it saves us expenses. We may do this
based on the size and type of the group and the amount of the contributions.
    

   
We won't unlawfully discriminate against any person or group if we reduce or
eliminate these charges.
    

   
PORTFOLIO CHARGES
    

   
The Separate Account buys shares of the Portfolios at net asset value. That
price reflects investment advisory fees and other direct expenses that have
already been deducted from the assets of the Portfolios. The amount charged for
investment management can't be increased without the approval of the
shareholders.
    

   
STATE PREMIUM TAX DEDUCTION
    

   
National Integrity won't deduct state premium taxes from your contributions
before investing them in the Investment Options, unless required to by your
state law. If the Annuitant elects an annuity benefit, we'll deduct any
applicable state premium taxes from the amount otherwise available for an
annuity benefit. State premium taxes currently range up to 4%.
    

   
TRANSFER CHARGE
    

   
If you make more than twelve transfers among your Investment Options during one
contract year, we may charge your account up to $20 for each additional transfer
during that year. Transfer charges don't apply to transfers under (i) Dollar
Cost Averaging, (ii) Customized Asset Rebalancing, (iii) the Callan Asset
Allocation and Rebalancing Program, or (iv) under systematic transfers from the
STO, nor will such transfers count towards the twelve free transfers you may
make in a contract year.
    

   
TAX RESERVE
    

   
We can make a charge in the future for taxes or for reserves set aside for
taxes, which will reduce the investment experience of the Variable Account
Options.
    

   
PART 5 - TERMS OF YOUR VARIABLE ANNUITY
    

   
CONTRIBUTIONS UNDER YOUR CONTRACT
    

   
You can make contributions of at least $100 at any time up to the Annuitant's
Retirement Date. Your first contribution, however, cannot be less than $1,000.
We'll accept contributions of at least $50 for salary allotment programs. We
have special rules for minimum contribution amounts for tax-favored retirement
programs. See "Special Rules for Tax-Favored Retirement Programs" in Part 7.
    

   
We may limit the total contributions under one contract to $1,000,000 if you are
under age 76 or to $250,000 if you are over age 76. Once you reach eight years
before your Retirement Date, we may refuse to accept any contribution.
Contributions may also be limited by various laws or prohibited by National
Integrity for all Annuitants under the contract. If your contributions are made
under a tax-favored retirement program, we won't measure them against the
maximum limits set by law.
    

   
Contributions are applied to the various Investment Options you select and are
used to pay annuity and death benefits. Each contribution is credited as of the
date we have RECEIVED (as defined below) at our Administrative Office both the
contribution and instructions for allocation among the Investment Options,
PROVIDED THAT AT ANY TIME YOU MAY NOT HAVE AMOUNTS IN MORE THAN NINE INVESTMENT
OPTIONS. In determining the nine Investment Options, each of your GRO Accounts
counts as one Investment Option. Wire transfers of federal funds are deemed
received on the day of transmittal if credited to our account by 3 p.m. Eastern
Time, otherwise they are deemed received on the next Business 
    

<PAGE>

   
Day. Contributions by check or mail are deemed received when they are delivered
in good order to our Administrative Office. A BUSINESS DAY is defined as any day
that the New York Stock Exchange is open.
    

   
You can change your choice of Investment Options at any time by writing to the
Administrative Office. The request should indicate your contract number and the
specific change you want to make, and you should sign the request. When the
Administrative Office receives it, the change will be effective for any
contribution that accompanies it and for all future contributions. We can also
accept changes by telephone transfer. See "Transfers" in Part 5.
    

   
YOUR ACCOUNT VALUE
    

   
Your Account Value reflects various charges. See Part 4, "Deductions and
Charges." Annual deductions are made as of the last day of each contract year.
Market Value Adjustments, if applicable, are made as of the effective date of
the transaction. Charges against our Separate Account are reflected daily. Any
amount allocated to a Variable Account Option will go up or down in value
depending on the investment experience of that Option. The value of
contributions made to the Variable Account Options isn't guaranteed. The value
of your contributions made to GROs is guaranteed, subject to any applicable
Market Value Adjustments. See "Guaranteed Rate Options" in Part 3.
    

   
YOUR PURCHASE OF UNITS IN OUR SEPARATE ACCOUNT
    

   
Allocations to the Variable Account Options are used to purchase units. On any
given day, the value you have in a Variable Account Option is the unit value
multiplied by the number of units credited to you in that Option. The units of
each Variable Account Option have different unit values.
    

   
The number of units purchased or redeemed (sold) in any Variable Account Option
is calculated by dividing the dollar amount of the transaction by the Option's
unit value, calculated after the close of business that day. The number of units
for a Variable Account Option at any time is the number of units purchased less
the number of units redeemed. The value of units fluctuates with the investment
performance of the corresponding Portfolios, which in turn reflects the
investment income and realized and unrealized capital gains and losses of the
Portfolios, as well as their expenses. The unit values also change because of
deductions and charges we make to our Separate Account. The number of units
credited to you, however, won't vary because of changes in unit values. Units of
a Variable Account Option are purchased when you make new contributions or
transfer contributions you made to a different Option into that Option. Units
are redeemed when you make withdrawals or transfer amounts out of a Variable
Account Option into a different Option. We also redeem units to pay the death
benefit when the Annuitant dies and to pay the annual administrative charge.
    

   
HOW WE DETERMINE UNIT VALUE
    

   
We determine unit values for each Variable Account Option on the Valuation Date.
The Valuation Date for purposes of determining unit values is 4 p.m. Eastern
Time on each day the New York Stock Exchange is open for business.
    

   
The unit value of each Variable Account Option for any day on which we determine
unit values is equal to the unit value for the last day on which a unit value
was determined multiplied by the net investment factor for that Option on the
current day. We determine a NET INVESTMENT FACTOR for each Option as follows:
    

   
- -    First, we take the value of the shares belonging to the Option in the
     corresponding Portfolio at the close of business that day (before giving
     effect to any transactions for that day, such as contributions or
     withdrawals). For this purpose, we use the share value reported to us by
     the Portfolios.
    

   
- -    Next, we add any dividends or capital gains distributions by the Portfolio
     on that day.
    

   
- -    Then, we charge or credit for any taxes or amounts set aside as a reserve
     for taxes.
    

   
- -    Then, we divide this amount by the value of the amounts in the Option at
     the close of business on the last day on which a unit value was determined
     (after giving effect to any transactions on that day).
    

<PAGE>

   
- -    Finally, we subtract a daily asset charge for each calendar day since the
     last day on which a unit value was determined (for example, a Monday
     calculation will include charges for Saturday and Sunday). The daily charge
     is .00003721, which is an effective annual rate of 1.45%. This charge is
     for the mortality risk, administrative expenses and expense risk assumed by
     us under the contract.
    

   
Generally, this means that we adjust unit values to reflect what happens to the
Portfolio, and also for the mortality and expense risk charge and any charge for
administrative expenses or taxes.
    

   
TRANSFERS
    

   
You may transfer your Account Value among the Variable Account Options and the
GROs, subject to National Integrity's then current transfer restrictions.
Transfers to a GRO must be to a newly elected GRO (i.e. to a GRO that you
haven't already purchased) at the then-current Guaranteed Interest Rate, unless
we agree otherwise. Transfers you make from a GRO, except within 30 days before
your GRO Account expires, are subject to a Market Value Adjustment. See
"Guaranteed Rate Options" in Part 3. Transfers from GROs, will be made according
to the order in which money was originally allocated to the GRO.
    

   
The amount transferred must be at least $250 or, if less, the entire amount in
the Investment Option. You have twelve free transfers during a contract year.
After those twelve transfers, a charge of up to $20 may apply to each additional
transfer during that contract year. No charge will be made for transfers under
our dollar cost averaging, Customized Asset Rebalancing, Asset Allocation and
Rebalancing Program or systematic transfer programs, described in Part 8. Once
annuity payments begin, transfers aren't permitted.
    

   
You may request a transfer by writing to our Administrative Office. Each request
for a transfer must specify the contract number, the amounts to be transferred
and the Investment Options to and from which the amounts are to be transferred.
Transfers may also be arranged through our telephone transfer service provided
you have established a Personal Identification Number (PIN CODE). We'll honor
telephone transfer instructions from any person who provides correct identifying
information. We aren't responsible for any fraudulent telephone transfers that
are believed to be genuine in accordance with these procedures. You bear the
risk of loss if unauthorized persons make transfers on your behalf.
    

   
A transfer request will be effective as of the Business Day our Administrative
Office receives it. A transfer request doesn't change the allocation of current
or future contributions among the Investment Options. Telephone transfers may be
requested from 9:00 a.m. - 5:00 p.m., Eastern Time, on any day we're open for
business. You'll receive the Variable Account Options' unit values as of the
close of business on the day you call. Transfer requests received after 4:00
p.m. Eastern Time (or the close of the New York Stock Exchange, if earlier) will
be processed using unit values as of the close of business on the next Business
Day after the day you call. All transfers will be confirmed in writing.
    

   
WITHDRAWALS
    

   
You may make any number of withdrawals as often as you wish. Each withdrawal
must be for at least $300. The money will be taken from your Accounts in the
same proportion as you contributed it to them. For example, if your
contributions are divided in equal 25% shares among four Investment Options,
when you make a withdrawal, 25% of the money withdrawn will come from each of
your Investment Options. You can tell us if you want your withdrawal handled
differently.
    

   
When you make a partial withdrawal, the total amount deducted from your Account
Value will include the withdrawal amount requested plus any Market Value
Adjustments. The total amount that you receive will be the total amount that you
requested. Most of the withdrawals you make before you are 59-1/2 years old are
subject to a 10% federal tax penalty. If your contract is part of a tax-favored
plan, the plan may limit your withdrawals. See Part 7, "Tax Aspects of the
Contracts."
    

   
ASSIGNMENTS
    

   
If your contract isn't part of a tax-favored program, you may assign the
contract before the Annuitant's Retirement Date. You can't, however, make a
partial assignment. An assignment of the contract may have adverse tax
consequences. See
    

<PAGE>

   
Part 7, "Tax Aspects of the Contracts." We won't be bound by an assignment
unless it is in writing and our Administrative Office has received it.
    

   
DEATH BENEFITS AND SIMILAR BENEFIT DISTRIBUTIONS
    

   
We'll pay a death benefit to the Annuitant's surviving beneficiary (or
beneficiaries, in equal shares) if the last Annuitant dies before annuity
payments have started. If the Annuitant dies at or over age 90 (or after the
Contract's 10th anniversary date, if later), the death benefit is the contract
account value at the end of the business day on which we receive proof of death.
Similarly, if the Contract was issued on or after the youngest Annuitant's 86th
birthday, the death benefit is the contract account value at the end of the
business day on which we receive proof of death.
    

   
For Contracts issued before the Annuitant's 86th birthday, if the Annuitant dies
before age 90 (or the Contract's 10th anniversary date, if later) before annuity
payments have started, the death benefit is the higher of:
    

   
     a)   the contract account value at the end of the business day on which we
          receive proof of death; or
    

   
     b)   the total of all contributions;
    

   
each reduced on a pro rata basis for prior withdrawals (after being adjusted for
any applicable market value adjustments and/or charges). We'll determine the
amount of the reduction by dividing the amount of the withdrawal by the annuity
account value on the transaction date and multiplying this percentage by the
then current guaranteed minimum death benefit.
    

   
Death benefits and benefit distributions required because of a separate Owner's
death can be paid in a lump sum or as an annuity. If a benefit option hasn't
been selected for the beneficiary at the Annuitant's death, the beneficiary can
select an option.
    

   
The Owner selects the beneficiary of the death benefit. An Owner may change
beneficiaries by sending the appropriate form to the Administrative Office. If
an Annuitant's beneficiary doesn't survive the Annuitant, then the death benefit
is generally paid to the Annuitant's estate. No death benefit will be paid after
the Annuitant's death if there is a contingent Annuitant. In that case, the
contingent Annuitant becomes the new Annuitant under the contract.
    

   
The death benefit described above becomes retroactive to all contracts issued on
or after January 1, 1997.
    

   
ANNUITY BENEFITS
    

   
All annuity benefits under your contract are calculated as of the Retirement
Date you select. You can change the Retirement Date by writing to the
Administrative Office any time before the Retirement Date. The Retirement Date
can't be later than your 90th birthday or earlier, if required by law. Contract
terms that apply to the various retirement programs, along with the federal tax
laws, establish certain minimum and maximum retirement ages.
    

   
Annuity benefits may be a lump sum payment or paid out over time as an annuity.
A lump sum payment will provide the Annuitant with the Cash Value under the
contract, shortly after the Retirement Date. The amount applied toward the
purchase of an annuity benefit will be the Adjusted Account Value, except that
the Cash Value will be the amount applied instead if the annuity benefit doesn't
have a life contingency and either the term is less than five years or the
annuity can be commuted to a lump sum payment.
    

   
ANNUITIES
    

   
Annuity benefits can provide for fixed or variable payments, which may be made
monthly, quarterly, semi-annually or annually. Variable payments will be funded
through one or more Separate Account Divisions. For any annuity, the minimum
amount applied to the annuity must be $2,000 and the minimum initial payment
must be at least $20.
    

   
If you haven't already selected a form of annuity, within six months prior to
your Retirement Date, we'll send you a notice form. You can tell us on the form
the type of annuity you want or confirm to us that we're to provide the normal
form of annuity, as defined below. However, if we don't receive a completed form
from you on or before your Retirement Date, we'll extend the Retirement Date
until we receive your written instructions at our Administrative Office. During
this 
    

<PAGE>

   
extension, the values under your contract in the various Investment Options
will remain invested in those options and amounts remaining in Variable Account
Options will continue to be subject to the associated investment risks. However,
your Retirement Date can't be extended beyond your 90th birthday or earlier, if
required by law. You'll receive a lump sum benefit if you don't make an election
by then.
    

   
We currently offer the following types of annuities:
    

   
The NORMAL FORM OF ANNUITY is a fixed life income annuity with 10 years of
payments guaranteed, funded through our General Account.
    

   
A PERIOD CERTAIN ANNUITY provides for fixed or variable payments, or both, to
the Annuitant or the Annuitant's beneficiary (the PAYEE) for a fixed period. The
amount is determined by the period selected. The Annuitant, or if the payee dies
before the end of the period selected, the payee's beneficiary, may elect to
receive the total present value of future payments in cash.
    

   
A PERIOD CERTAIN LIFE ANNUITY provides for fixed or variable payments, or both,
for at least the period selected and thereafter for the life of the payee or the
payee and another annuitant under a joint and survivor annuity. You can't change
or redeem the annuity once payments have begun. If the payee (or the payee and
the other annuitant under a joint and survivor annuity) dies before the period
selected ends, the remaining payments will go to another named payee. That payee
can redeem the annuity and receive the present value of future guaranteed
payments in a lump sum.
    

   
A LIFE INCOME ANNUITY provides fixed payments for the life of the payee or the
payee and another annuitant under a joint and survivor annuity. Once a life
income annuity is selected, the form of annuity can't be changed or redeemed for
a lump sum payment by the Annuitant or any payee.
    

   
ANNUITY PAYMENTS
    

   
Fixed annuity payments won't change and are based upon annuity rates provided in
your contract. The size of payments will depend on the form of annuity that was
chosen and, in the case of a life income annuity, on the payee's age (or payee
and a joint annuitant in the case of a joint and survivor annuity) and sex
(except under most tax-favored retirement programs). If our annuity rates then
in effect would yield a larger payment, those rates will apply instead of the
tables.
    

   
Variable annuity payments are funded only in the Separate Account Divisions
through the purchase of annuity units. The Variable Account Option or Options
selected can't be changed after annuity payments begin. The Statement of
Additional Information (SAI) has more information about the determination of
annuity payments. The number of units purchased is equal to the amount of the
first annuity payment divided by the new annuity unit value for the valuation
period that includes the due date of the first annuity payment. The amount of
the first annuity payment is determined in the same manner for a variable
annuity as it is for a fixed annuity. The number of annuity units stays the same
for the annuity payment period but the new annuity unit value changes to reflect
the investment income and the realized and unrealized capital gains and losses
of the Variable Account Option or Options selected, after charges made against
it. Annuity unit values assume a base rate of net investment return of 5%,
except in states which require a lower rate in which case 3.5% will be used. The
annuity unit value will rise or fall depending on whether the actual rate of net
investment return is higher or lower than the assumed base rate. In the SAI, see
"Determination of Annuity Unit Values."
    

   
If the age or sex of an annuitant has been misstated, any benefits will be those
which would have been purchased at the correct age and sex. Any overpayments or
underpayments made by us will be charged or credited with interest at the rate
of 6% per year. If we have made overpayments because of incorrect information
about age or sex, we will deduct the overpayment from the next payment or
payments due. We add underpayments to the next payment.
    

   
TIMING OF PAYMENT
    

   
We normally make payments from the Variable Account Options, or apply your
Adjusted Account Value to the purchase of an annuity within seven days after we
receive the required form at our Administrative Office. We can defer our action,
however, for any period during which
    

   
1.   the New York Stock Exchange has been closed or trading on it is restricted;
    

<PAGE>

   
2.   an emergency exists so that disposal of securities isn't reasonably
     practicable or it isn't reasonably practicable for a Separate Account
     fairly to determine the value of its net assets; or
    

   
3.   the SEC, by order, permits National Integrity to defer action in order to
     protect persons with interests in the Separate Account. National Integrity
     can defer payment of your GROs for up to six months, and interest will be
     paid on any such payment delayed for 30 days or more.
    

   
HOW YOU MAKE REQUESTS AND GIVE INSTRUCTIONS
    

   
When you write to our Administrative Office, use the address on the first page
of this prospectus. We can't honor your request or instruction unless it is in
proper and complete form. Whenever possible, use one of our printed forms, which
you can get from our Administrative Office.
    

   
PART 6 - VOTING RIGHTS
    

   
VOTING RIGHTS
    

   
National Integrity is the legal owner of the shares of the Portfolios held by
the Separate Account and, as such, has the right to vote on certain matters.
Among other things, we may vote to elect the Portfolios' Boards of Directors, to
ratify the selection of independent auditors for the Portfolios, and on any
other matters described in the Portfolios' current prospectus or requiring a
vote by shareholders under the 1940 Act.
    

   
Whenever a shareholder vote is taken, we give you the opportunity to tell us how
to vote the number of shares purchased as a result of contributions to your
contract. We'll send you Portfolio proxy materials and a form for giving us
voting instructions.
    

   
If we don't receive instructions in time from all Owners, we'll vote shares in a
Portfolio for which no instructions have been received in the same proportion as
we vote shares for which we have received instructions. Under eligible deferred
compensation plans and certain Qualified Plans, your voting instructions must be
communicated to us indirectly, through your employer, but we aren't responsible
for any failure by your employer to ask for your instructions or to tell us what
your instructions are. We'll vote any Portfolio shares that we're entitled to
vote directly, because of amounts we have accumulated in our Separate Account,
in the same proportions that other Owners vote. If the federal securities laws
or regulations or interpretations of them change so that we are permitted to
vote shares of the Portfolios in our own right or to restrict Owner voting, we
may do so.
    

   
HOW WE DETERMINE YOUR VOTING SHARES
    

   
You may participate in voting only on matters concerning the Portfolios in which
your contributions have been invested. We determine the number of Portfolio
shares in each Variable Account Option under your contract by dividing the
amount of your Account Value allocated to that Option by the net asset value of
one share of the corresponding Portfolio as of the record date set by the
Portfolios' Boards for the shareholders' meeting. We count fractional shares.
The record date for this purpose can't be more than 60 days before the meeting
of the shareholders. After annuity payments have begun, voting rights are
calculated in a similar manner based on the actuarially determined value of your
interest in each Variable Account Option.
    

   
HOW PORTFOLIO SHARES ARE VOTED
    

   
All Portfolio shares are entitled to one vote; fractional shares have fractional
votes. Voting is on a Portfolio-by-Portfolio basis, except for certain matters
(for example, election of Directors) that require collective approval. On
matters where the interests of the individual Portfolios differ, the approval of
the shareholders in one Portfolio isn't needed to make a decision in another
Portfolio. If shares of the Portfolios are sold to separate accounts of other
insurance companies, the shares voted by such companies in accordance with
instructions received from their contract holders will dilute the effect of
voting instructions received by National Integrity from its Owners.
    



<PAGE>

   
SEPARATE ACCOUNT VOTING RIGHTS
    
   
Under the 1940 Act, certain actions (such as some of those described under
"Changes in How We Operate" in Part 2) may require Owner approval. In that case,
you'll be entitled to a number of votes based on the value you have in the
Variable Account Options, as described above under "How We Determine Your Voting
Shares." We'll cast votes attributable to amounts we have in the Variable
Account Options in the same proportions as votes cast by Owners.
    
   
PART 7 - TAX ASPECTS OF THE CONTRACTS
    
   
INTRODUCTION
    
   
The effect of federal income taxes on the amounts held under a contract, on
annuity payments, and on the economic benefits to the Owner, Annuitant, and the
beneficiary or other payee may depend on National Integrity's tax status, on the
type of retirement plan, if any, for which the contract is purchased, and upon
the tax and employment status of the individuals concerned.
    
   
The following discussion of the federal income tax treatment of the contract
isn't designed to cover all situations and isn't intended to be tax advice. It's
based upon our understanding of the present federal income tax laws as currently
interpreted by the Internal Revenue Service (IRS) and various courts. We can't
guarantee that the tax code or the courts will or won't change their views on
the treatment of these contracts. Future legislation may affect annuity
contracts adversely. Moreover, we haven't attempted to consider any applicable
state or other tax laws. Because of the complexity of the tax laws and the fact
that tax results will vary according to the particular circumstances, any one
considering buying a contract, or selecting annuity payments under the contract,
or receiving annuity payments under a contract should consult a qualified tax
adviser. NATIONAL INTEGRITY DOESN'T MAKE ANY GUARANTEE REGARDING THE TAX STATUS,
FEDERAL, STATE, OR LOCAL, OF ANY CONTRACT OR ANY TRANSACTION INVOLVING THE
CONTRACTS.
    
   
YOUR CONTRACT IS AN ANNUITY
    
   
Under federal tax law, anyone can purchase an annuity with after-tax dollars and
your annuity earnings won't be taxed until you make a withdrawal. Or, an
individual (or employer) may buy the annuity to fund a tax-favored retirement
program (contributions are with pre-tax dollars), such as an IRA or qualified
plan. Finally, the individual (or employer) may buy the Annuity to fund a Roth
IRA (contributions are with after-tax dollars and earnings are excluded in
taxable income at distribution).
    
   
This prospectus covers the basic tax rules that apply to an annuity purchased
directly with after-tax dollars, (NONQUALIFIED ANNUITY), and some of the special
tax rules which apply to an annuity purchased to fund a tax-favored retirement
program, (QUALIFIED ANNUITY). A qualified annuity may restrict your rights and
benefits to qualify for its special treatment under the federal tax law.
    
   
TAXATION OF ANNUITIES GENERALLY
    
   
Section 72 of the Code governs the taxation of annuities. In general,
contributions you put into the annuity (your "basis" or "investment" in the
contract) won't be taxed when you receive those amounts back in a distribution.
Also, an Owner isn't taxed on the annuity's earnings until some form of
withdrawal or distribution is made under the contract. However, under certain
circumstances, the increase in value may be subject to current federal income
tax. For example, corporations, partnerships, and other non-natural persons
can't defer tax on the annuity's income unless an exception applies. In
addition, if an Owner transfers an annuity as a gift to someone other than a
spouse (or former spouse), all increases in its value will be taxed at the time
of transfer. The assignment or pledge of any portion of the value of a contract
will be treated as a distribution of that portion of the value of the contract.
    
   
You can take withdrawals from the contract or you can wait to annuitize it when
the annuitant reaches a certain age. The tax implications are different for each
type of distribution. Section 72 of the Code says that the proceeds of a full or
partial withdrawal from a contract before annuity payments begin are first
treated as taxable income, but only to the extent of the increase of the Account
Value. The rest of the withdrawal, representing your basis in the annuity, isn't
taxable. Generally, the investment or basis in the contract equals the
contributions made by or on your behalf, minus any amounts
    
<PAGE>

   
previously withdrawn that were not treated as taxable income. Special rules may
apply if the contract includes contributions made prior to August 14, 1982 that
were rolled over to the contract in a tax-free exchange.
    
   
If you take annuity payments over the lifetime of the annuitant, part of each
payment is considered to be a tax-free return of your investment. This
non-taxable portion of each payment is figured using a ratio of the Owner's
investment to his or her expected return under the contract (exclusion Ratio).
Once you get the tax-free part, the rest of each payment will be considered the
increase of your Account Value, and is ordinary income. That means that part of
your payment is tax-free and part is taxable. When all of these tax-free
portions add up to your investment in the annuity, future payments are all
counted as an increase in your Account Value, and are taxable income. If the
Annuitant dies before recovering the total investment, a deduction for the
remaining basis will generally be allowed on the Owner's final federal income
tax return.
    
   
We may be required to withhold federal income taxes on all distributions unless
the eligible recipient elects not to have any amounts withheld and properly
notifies us of that election.
    
   
The taxable portion of a distribution is treated as ordinary income and is taxed
at ordinary income tax rates. In addition, you may be subject to a tax penalty
of 10% on the taxable portion of a distribution unless it is:
    
   
1.   on or after the date on which the taxpayer attains age 59-1/2;
2.   as a result of the death of the Owner;
3.   part of a series of substantially equal periodic payments (paid at least
     annually) for the life (or life expectancy) of the taxpayer or joint lives
     (or joint life expectancies) of the taxpayer and beneficiary;
4.   attributable to the taxpayer becoming disabled within the meaning of Code
     Section 72(m)(7);
5.   from certain qualified plans (note, however, other penalties may apply);
6.   under a qualified funding asset (as defined in Section 130(d) of the Code);
7.   purchased by an employer on termination of certain types of qualified plans
     and held by the employer until the employee separates from service;
8.   under an immediate annuity as defined in Code Section 72(u)(4); or
9.   purchase of a first home (distribution up to $10,000);
10.  for certain higher education expenses; or
11.  to cover certain deductible medical expenses.
    
   
Please note that items (9), (10) and (11) apply to IRAs only.
    
   
Any withdrawal provisions of your contract will also apply. See "Withdrawals" in
Part 5.
    
   
All annuity contracts issued by National Integrity or its affiliates to one
Annuitant during any calendar year are treated as a single contract in measuring
the taxable income that results from surrenders and withdrawals under any one of
the contracts.
    
   
DISTRIBUTION-AT-DEATH RULES
    
   
Under section 72(s) of the Code, to be treated as an annuity, a contract must
provide the following distribution rules: (a) if any Owner dies on or after the
Retirement Date and before the entire interest in the contract has been
distributed, then the rest of that annuity must be distributed at least as
quickly as the method in effect when the Owner died; and (b) if any Owner dies
before the Retirement Date, the entire interest in the contract must be
distributed within five years. However, any interest that is payable to a death
beneficiary may be annuitized over the life of that beneficiary or over a period
not extending beyond the life expectancy of that beneficiary, so long as
distributions begin within one year after the Owner's death. If the beneficiary
is the Owner's spouse, the contract (along with the deferred tax status) may be
continued in the spouse's name as the Owner.
    
   
DIVERSIFICATION STANDARDS
    
   
National Integrity manages the investments in the annuities under Section 817(h)
of the Code to ensure that they will be taxed as described above.
    

<PAGE>

   
TAX-FAVORED RETIREMENT PROGRAMS
    
   
An Owner can use this annuity with certain types of retirement plans that
receive favorable treatment under the Code. Numerous tax rules apply to the
participants in qualified plans and to the contracts used in connection with
those qualified plans. These tax rules vary according to the type of plan and
the terms and conditions of the plan itself. Owners, Annuitants, and
beneficiaries are cautioned that the rights of any person to any benefits under
qualified plans may be subject to the terms and conditions of the plans
themselves, regardless of the terms and conditions of the contract. In addition,
loans from qualified contracts, where allowed, are subject to a variety of
limitations, including restrictions as to the amount that may be borrowed, the
duration of the loan, and the manner in which the loans must be repaid. (Owners
should always consult their tax advisors and retirement plan fiduciaries before
taking any loans from the plan.) Special rules also apply to the time at which
distributions must begin and the form in which the distributions must be paid.
THE STATEMENT OF ADDITIONAL INFORMATION CONTAINS GENERAL INFORMATION ABOUT THE
USE OF CONTRACTS WITH THE VARIOUS TYPES OF QUALIFIED PLANS.
    
   
FEDERAL AND STATE INCOME TAX WITHHOLDING
    
   
Certain states have indicated that pension and annuity withholding will apply to
payments made to residents. Generally, an election out of federal withholding
will also be considered an election out of state withholding. For more
information concerning a particular state, call our Administrative Office at the
toll-free number.
    
   
IMPACT OF TAXES TO NATIONAL INTEGRITY
    
   
The contracts provide that National Integrity may charge the Separate Account
for taxes. National Integrity can also set up reserves for taxes.
    
   
TRANSFERS AMONG INVESTMENT OPTIONS
    
   
There will not be any tax liability if you transfer any part of the Account
Value among the Investment Options of your contract.
    
   
PART 8 - ADDITIONAL INFORMATION
    
   
SYSTEMATIC WITHDRAWALS
    
   
We offer a program for systematic withdrawals that allows you to pre-authorize
periodic withdrawals from your contract prior to your Retirement Date. You can
choose to have withdrawals made monthly, quarterly, semi-annually or annually
and may specify the day of the month (other than the 29th, 30th or 31st) on
which the withdrawal is to be made. You may specify a dollar amount for each
withdrawal or an annual percentage to be withdrawn. The minimum systematic
withdrawal currently is $100. You may also specify an account for direct deposit
of your systematic withdrawals. To enroll in our systematic withdrawal program,
send the appropriate form to our Administrative Office. Withdrawals may begin as
soon as one business day after we receive the form. You may terminate your
participation in the program upon one day's prior written notice, and we may
terminate or change the systematic withdrawal program at any time. If on any
withdrawal date you don't have enough money in your Account to make all of the
withdrawals you have specified, no withdrawal will be made and your enrollment
in the program will be ended.
    
   
Amounts you withdraw under the systematic withdrawal program may be within the
free withdrawal amount. If so, we won't make a Market Value Adjustment. AMOUNTS
WITHDRAWN FROM YOUR GRO ACCOUNT UNDER THE SYSTEMATIC WITHDRAWAL PROGRAM IN
EXCESS OF THE FREE WITHDRAWAL AMOUNT WILL BE SUBJECT TO AN ADMINISTRATIVE
EXPENSE CHARGE AND A MARKET VALUE ADJUSTMENT IF APPLICABLE. WITHDRAWALS ALSO MAY
BE SUBJECT TO THE 10% FEDERAL TAX PENALTY FOR EARLY WITHDRAWALS UNDER THE
CONTRACTS AND TO INCOME TAXATION. See Part 7, "Tax Aspects of the Contracts."
    
   
INCOME PLUS WITHDRAWAL PROGRAM
    
   
We offer the Income Plus Withdrawal Program that allows you to pre-authorize
substantially equal periodic withdrawals, based on your life expectancy, from
your contract prior to your reaching age 59-1/2. You won't have to pay any tax
    

<PAGE>

   
penalty for these withdrawals, but they will be subject to ordinary income tax.
See "Taxation of Annuities Generally," in Part 7. Once you begin receiving
distributions, they shouldn't be changed or stopped until the later of:
    
   
- -    the date your reach age 59-1/2; or
- -    five years from the date of the first distribution.
    
   
If you change or stop the distribution or take an additional withdrawal, you may
have to pay a 10% penalty tax that would have otherwise been due on all prior
distributions before you reached age 59-1/2 made under the Income Plus Program
plus interest.
    
   
You can choose the Income Plus Withdrawal Program any time before you reach age
59-1/2. You can elect this option by sending the election form to our
Administrative Office. You may choose to have withdrawals made monthly,
quarterly, semi-annually or annually and may specify the day of the month (other
than the 29th, 30th or 31st) on which the withdrawal is to be made. We'll
calculate the amount of the distribution under a method you select, subject to a
minimum, which is currently $100. You must also specify an account for direct
deposit of your Income Plus Withdrawals.
    
   
To enroll under our Income Plus Withdrawal Program, send the appropriate form to
our Administrative Office. Withdrawals may begin as soon as one Business Day
after we receive the form. You may terminate your participation in the program
upon seven Business Days prior written notice, and we may terminate or change
the Income Plus Program at any time. If on any withdrawal date you do not have
enough money in your Accounts to make all of the withdrawals you have specified,
no withdrawal will be made and your enrollment in the program will be ended.
This program isn't available in connection with the Systematic Withdrawal
Program, Dollar Cost Averaging, Systematic Transfer Option or Asset Allocation
and Rebalancing Program.
    
   
AMOUNTS WITHDRAWN UNDER THE INCOME PLUS WITHDRAWAL PROGRAM IN EXCESS OF THE FREE
WITHDRAWAL AMOUNT WILL BE SUBJECT TO A MARKET VALUE ADJUSTMENT IF APPLICABLE.
    
   
DOLLAR COST AVERAGING
    
   
We offer a dollar cost averaging program under which we transfer contributions
that you have made to the VIP Money Market Option on a monthly, quarterly,
semi-annual or annual basis to one or more other Variable Account Options. You
must tell us how much you want to be transferred into each Variable Account
Option. The current minimum transfer to each Option is $250. We won't charge a
transfer charge under our dollar cost averaging program and these transfers
won't count towards your twelve free transfers.
    
   
To enroll in our dollar cost averaging program, send the appropriate form to our
Administrative Office. You may terminate your participation in the program upon
one day's prior written notice, and we may terminate or change the dollar cost
averaging program at any time. If you do not have enough money in the VIP Money
Market Option to transfer to each Variable Account Option specified, no transfer
will be made and your enrollment in the program will be ended.
    
   
CUSTOMIZED ASSET REBALANCING
    
   
We offer a Customized Asset Rebalancing program that allows you to determine how
often rebalancing occurs. You can choose to rebalance monthly, quarterly,
semi-annually or annually. The value in the Variable Account Options will
automatically be rebalanced by transfers among those Options, and you will
receive a confirmation notice after each rebalancing. Transfers will occur only
to and from those Variable Account Options where you have current contribution
allocations. We won't charge a transfer charge for transfers under our
Customized Asset Rebalancing program, and they won't count towards your twelve
free transfers.
    
   
GROs aren't eligible for the Customized Asset Rebalancing program.
    
   
To enroll in our Customized Asset Rebalancing program, send the appropriate form
to our Administrative Office. You should be aware that other allocation
programs, such as dollar cost averaging, as well as transfers and withdrawals
that you make, may not work with the Customized Asset Rebalancing program. You
should, therefore, monitor your use of other programs, transfers, and
withdrawals while the Customized Asset Rebalancing program is in effect. You may
terminate 
    

<PAGE>

   
your participation in the program upon one day's prior written notice, and we
may terminate or change the Customized Asset Rebalancing program at any time.
    
   
CALLAN ASSET ALLOCATION AND REBALANCING PROGRAM
    
   
We offer an Asset Allocation and Rebalancing Program developed in consultation
with Callan Associates. Callan Associates is an independent research and
consulting firm, specializing in the strategic asset allocation decision.
    
   
You may select one of five proposed Asset Allocation Rebalancing Models:
Conservative, Moderately Conservative, Moderate, Moderately Aggressive, or
Aggressive. The contribution you are making will initially be allocated among
the Options currently established for each Model. If we change the Model, your
account values will be automatically reallocated accordingly unless you have
terminated your participation. You and your financial representative also have
the option to design a program that is tailored to your specific retirement
needs.
    
   
When you select this program, your account values will be allocated and your
variable portfolios will be rebalanced automatically at least annually. The
program automatically applies to all contributions made to your annuity contract
while you are still participating. You will receive a confirmation notice after
each rebalancing. We won't charge a transfer charge for transfers made under the
Asset Allocation and Rebalancing Program. These transfers won't count toward
your twelve free transfers.
    
   
In each Asset Allocation Rebalancing Model, a part of each contribution is
allocated to a five-year Guaranteed Rate Option (GRO). The amount allocated to
the GRO won't be reallocated or rebalanced while you are participating in a
specific Model. You may cancel or change the Model you have selected at any
time. If you withdraw or transfer your GRO funds, they may be subject to a
Market Value Adjustment that may increase or decrease your account value.
    
   
To enroll in the Asset Allocation and Rebalancing Program, complete the
appropriate form and send it to our Administrative Office. You should be aware
that other allocation programs, such as dollar cost averaging, as well as
transfers and withdrawals that you make, may not work with the Customized Asset
Rebalancing program. If, after selecting one of the five models, you request a
transaction that results in a reallocation outside one of the Models, your
participation in the Model program automatically ends. You should, therefore,
monitor your use of such other programs, transfers, and withdrawals while the
Customized Asset Rebalancing program is in effect. This program isn't available
with the Customized Asset Rebalancing program. We can terminate or change this
program in whole or in part, or restrict contributions to the program. This
program may not be available in all states.
    
   
You may terminate participation in this program upon one day's prior written
notice.
    
   
PERFORMANCE INFORMATION
    
   
Performance data for the Variable Account Options, including the yield and
effective yield of the VIP Money Market Option, the yield of the other Options,
and the total return of all of the Options may appear in advertisements or sales
literature. This performance data is based only the performance of a
hypothetical investment in that Option during the particular time period on
which the calculations are based. Performance information should be considered
in light of the investment objectives and policies of the Portfolio in which the
Option invests and the market conditions during the given time frame. It
shouldn't be considered as a representation of performance to be achieved in the
future.
    
   
TOTAL RETURNS are based on the overall dollar or percentage change in value of a
hypothetical investment in an Option. Total return information reflects changes
in Portfolio share price, the automatic reinvestment of all distributions and
the deduction of contract charges and expenses that may apply. Total returns
also may be shown that don't take into account the annual administrative charge
that is applied when the Account Value is less than $50,000 at the end of the
contract year.
    
   
CUMULATIVE TOTAL RETURNS show an Investment Option's performance over a specific
period of time, usually seven years. An AVERAGE ANNUAL TOTAL RETURN shows the
hypothetical yearly return that would have produced the same cumulative total
return if the Investment Option experienced exactly the same return each year
for the entire period shown. Because performance will fluctuate on a
year-by-year basis, the average annual total returns tend to show a smooth
result that won't mirror actual performance, even though the end result will be
the same.
    

<PAGE>

   
Some Investment Options may also advertise YIELD, which shows the income
generated by an investment in that particular Option over a specified period of
time. This income is annualized and shown as a percentage. Yields don't take
into account capital gains or losses.
    
   
The VIP Money Market Option may advertise its CURRENT and EFFECTIVE YIELD.
Current yield reflects the income generated by an investment in that Option over
a specified seven-day period. Effective yield is calculated in a similar manner
except that it assumes that the income earned is reinvested, and the income on
the reinvested amount is included. The VIP II Investment Grade Bond and VIP High
Income Option may advertise a 30-day yield which reflects the income generated
by an investment in that Option over a specified 30-day period.
    
   
For a detailed description of the methods used to determine yield and total
return for the Variable Account Options, see the Statement of Additional
Information.

APPENDIX B
    
   
ILLUSTRATION OF A MARKET VALUE ADJUSTMENT

       Contribution:                      $50,000.00

       GRO Account duration:              7 Years

       Guaranteed Interest Rate: 5% Annual Effective Rate
    
   
The following examples illustrate how the Market Value Adjustment may affect the
values of a contract upon a withdrawal. The 5% assumed Guaranteed Interest Rate
is the same rate used in the Example under "Table of Annual Fees and Expenses"
in this Prospectus. In these examples, the withdrawal occurs three years after
the initial contribution. The Market Value Adjustment operates in a similar
manner for transfers.
    
   
The GRO Value for this $50,000 contribution is $70,355.02 at the expiration of
the GRO Account. After three years, the GRO Value is $57,881.25. It is also
assumed, for the purposes of these examples, that no prior partial withdrawals
or transfers have occurred.
    
   
The Market Value Adjustment will be based on the rate we are then crediting (at
the time of the withdrawal) on new contributions to GRO Accounts of the same
duration as the time remaining in your GRO Account, rounded to the next higher
number of complete months. If we do not declare a rate for the exact time
remaining, we will interpolate between the Guaranteed Interest Rates for GRO
Accounts of durations closest to (next higher and next lower) the remaining
period described above. Three years after the initial contribution, there would
have been four years remaining in your GRO Account.
    
   
EXAMPLE OF A DOWNWARD MARKET VALUE ADJUSTMENT:
    
   
A downward Market Value Adjustment results from a full or partial withdrawal
that occurs when interest rates have increased. Assume interest rates have
increased three years after the initial contribution and we are then crediting
6.25% for a four-year GRO Account. Upon a full withdrawal, the Market Value
Adjustment, applying the above formula would be:
    
   
                           48/12                     48/12
    -0.0551589 = [(1 + .05)     / (1 + .0625 + .0025)     ] - 1
    
   
The Market Value Adjustment is a reduction of $3,192.67 from the GRO Value:
    
   
    -$3,192.67 = -0.0551589 X $57,881.25
    
   
Thus, the amount payable on a full withdrawal (the Market Adjusted Value) would
be:
    
   
             $54,688.58 = $57,881.25 - $3,192.67
    
   
If instead of a full withdrawal, $20,000 were requested, we would first
determine the free withdrawal amount:
    
   
    $5,788.13 = $57,881.25 X .10

The non-free amount would be:
    
   
    $14,211.87 = $20,000.00 - $5,788.13
    
   
The Market Value Adjustment, which is only applicable to the non-free amount,
would be
    
   
    - $783.91 = -0.0551589 X $14,211.87
    
   
Thus, the total amount needed to provide $20,000 after the Market Value
Adjustment would be:
    

<PAGE>

   
    $20,783.91 = $20,000.00 + $783.91
    
   
The ending Account Value would be:
    
   
    $37,097.34 = $57,881.25 - $20,783.91
    
   
EXAMPLE OF AN UPWARD MARKET VALUE ADJUSTMENT:
    
   
An upward Market Value Adjustment results from a full or partial withdrawal that
occurs when interest rates have decreased. Assume interest rates have decreased
three years after the initial contribution and we are then crediting 4% for a
four-year GRO Account. Upon a full withdrawal, the Market Value Adjustment,
applying the formula set forth in the prospectus, would be:
    
   
                         48/12                    48/12
    .0290890 = [(1 + .05)      / (1 + .04 + .0025)     ] - 1
    
   
The Market Value Adjustment is an increase of $1,683.71 to the GRO Value:
    
   
    $1,683.71 = .0290890 X $57,881.25
    
   
The Market Adjusted Value would be:
    
   
    $59,564.96 = $57,881.25 + $1,683.71
    
   
Thus, the amount payable on a full withdrawal would be:
    
   
    $59,564.96 = $57,881.25 + $1,683.71
    
   
If instead of a full withdrawal, $20,000 were requested, the free withdrawal
amount and non-free amount would first be determined as above:
    
   
            Free Amount =    $ 5,788.13
    
   
     Non-Free Amount =    $14,211.87
    
   
The Market Value Adjustment would be:
    
   
    $413.41 = .0290890 X $14,211.87
    
   
Thus, the total amount needed to provide $20,000 after the Market Value
Adjustment would be:
    
   
    $19,586.59 = $20,000.00 - $413.41
    
   
The ending Account Value would be:
    
   
    $38,294.66 = $57,881.25 - $19,586.59
    
   
Actual Market Value Adjustments may have a greater or lesser impact than shown
in the examples, depending on the actual change in interest crediting rate and
the timing of the withdrawal or transfer in relation to the time remaining in
the GRO Account. Also, the Market Value Adjustment can never decrease the
Account Value below premium plus 3% interest, before any applicable charges.
Account values less than $50,000 will be subject to a $30 annual charge.

PART 1 - NATIONAL INTEGRITY AND CUSTODIAN
    

   
National Integrity Life Insurance Company is a New York stock life insurance
company that sells life insurance and annuities. Its principal executive offices
are located at 15 Matthews Street, Suite 200, Goshen, NY 10924. National
Integrity, the depositor of Separate Account I, is a wholly owned subsidiary of
Integrity Life Insurance Company, an Ohio corporation. All outstanding shares of
Integrity Life Insurance Company are owned by ARM Financial Group, Inc. (ARM), a
Delaware corporation that's a financial services company focusing on the
long-term savings and retirement marketplace by providing retail and
institutional products and services throughout the United States. ARM owns 100%
of the stock of (i) ARM Securities Corporation (ARM SECURITIES), a Minnesota
corporation, registered with the SEC as a broker-dealer and a member of the
National Association of Securities Dealers, Inc., (ii) Integrity Capital
Advisors, Inc., a Delaware corporation registered with the SEC as an investment
adviser, (iii) SBM Certificate Company, a Minnesota corporation registered with
the SEC as an issuer of face-amount certificates, and (iv) ARM Transfer Agency,
Inc., a Delaware corporation registered with the SEC as a transfer and dividend
disbursing agency.
    

   
ARM is 100% publicly owned, trading on the New York Stock Exchange (NYSE). No
one has the direct or indirect power to control ARM, except power he or she may
have by virtue of his or her capacity as a director or executive officer of ARM;
no individual beneficially owns more than 5% of the common shares.
    

   
    

   
Since 1994, ARM has provided substantially all of the services required to be
performed on behalf of the Separate Account. Total fees paid to ARM by National
Integrity for management services in 1997 were $5,855,216 and in 1998 were
$8,766,003 including services applicable to the Registrant.
    

   
National Integrity is the custodian for the shares of the Funds owned by the
Separate Account. The Funds' shares are held in book-entry form.
    

   
Reports and marketing materials, from time to time, may include information
concerning the rating of National Integrity, as determined by A.M. Best Company,
Moody's Investor Service, Standard & Poor's Corporation, Duff & Phelps
Corporation, or other recognized rating services. National Integrity is
currently rated "A" (Excellent) by A.M. Best Company, and has received claims
paying ability ratings of "A" (Good) from Standard & Poor's Corporation, "Baa1"
from Moody's Investors Service, Inc., and "A+" (High) from Duff and Phelps
Credit Rating Company. However, National 
    

<PAGE>

   
Integrity doesn't guarantee the investment performance of the
portfolios, and these ratings don't reflect protection against investment risk.
    

PART 2 - DISTRIBUTION OF THE CONTRACTS

   
ARM Securities, a wholly owned subsidiary of ARM, is the principal underwriter
of the contracts. ARM Securities is registered with the SEC as a broker-dealer
and is a member in good standing of the National Association of Securities
Dealers, Inc. ARM Securities' address is 515 West Market Street, Louisville,
Kentucky 40202. The contracts are offered through ARM Securities on a continuous
basis.
    

   
We generally pay a maximum distribution allowance of 6% of initial and
additional contributions, plus .30% trail commission paid on Account Value after
the 2nd Contract Year or 2.25% of initial and additional contributions plus 1%
trail commission paid on Account Value after the 2nd Contract Year. The amount
of distribution allowances paid was $1,753,582 for the year ended December 31,
1998, $2,647,756 for the year ended December 31, 1997 and $2,229,269 for the
year ended December 31, 1996. Distribution allowances weren't retained by ARM
Securities during these years. National Integrity may from time to time pay or
allow additional promotional incentives, in the form of cash or other
compensation, to broker-dealers that sell contracts. In some instances, those
types of incentives may be offered only to certain broker-dealers that sell or
are expected to sell certain minimum amounts of the contracts during specified
time periods.
    

PART 3 - PERFORMANCE INFORMATION

   
Each Variable Account Option may from time to time include the Average Annual
Total Return, the Cumulative Total Return, and Yield of its shares in
advertisements or in information furnished to shareholders. The VIP Money Market
Option may also from time to time include the Yield and Effective Yield of its
shares in information furnished to shareholders. Performance information is
computed separately for each Option in accordance with the formulas described
below. At any time in the future, total return and yields may be higher or lower
than in the past and we can't guarantee that any historical results will
continue.
    

TOTAL RETURNS

   
Total returns reflect all aspects of an Option's return, including the automatic
reinvestment by the Option of all distributions and the deduction of all charges
that apply to the Option on an annual basis, including mortality risk and
expense charges, the annual administrative charge and other charges against
contract values. For purposes of charges not based upon a percentage of contract
values, an average account value of $40,000 has been used. Quotations also will
assume a termination (surrender) at the end of the particular period and reflect
the deductions of the contingent withdrawal charge, if they would apply. Any
total return calculation will be based upon the assumption that the Option
corresponding to the investment portfolio was in existence throughout the stated
period and that the applicable contractual charges and expenses of the Option
during the stated period were equal to those that currently apply under the
contract. Total returns may be shown at the same time that do not take into
account deduction of the contingent withdrawal charge, and/or the annual
administrative charge.
    

   
AVERAGE ANNUAL TOTAL RETURNS are calculated by determining the growth or decline
in value of a hypothetical historical investment in the Option over certain
periods, including 1, 3, 5, and 10 years (up to the life of the Option), and
then calculating the annually compounded percentage rate that would have
produced the same result if the rate of growth or decline in value had been
constant over the period. Investors should realize that the Option's 
    

<PAGE>

   
performance is not constant over time, but changes from year to year, and that
the average annual returns represent the averages of historical figures as
opposed to the actual historical performance of an Option during any portion of
the period shown. Average annual returns are calculated pursuant to the
following formula: P(1+T)n = ERV, where P is a hypothetical initial payment of
$1,000, T is the average annual total return, n is the number of years, and ERV
is the withdrawal value at the end of the period.
    

CUMULATIVE TOTAL RETURNS are UNAVERAGED and reflect the simple percentage change
in the value of a hypothetical investment in the Option over a stated period of
time. In addition to the period since inception, cumulative total returns may be
calculated on a year-to-date basis at the end of each calendar month in the
current calendar year. The last day of the period for year-to-date returns is
the last day of the most recent calendar month at the time of publication.

YIELDS

   
Some Options may advertise yields. Yields quoted in advertising reflect the
change in value of a hypothetical investment in the Option over a stated period
of time, not taking into account capital gains or losses or any contingent
withdrawal charge. Yields are annualized and stated as a percentage.
    

   
CURRENT YIELD and EFFECTIVE YIELD are calculated for the VIP Money Market
Option. Current Yield is based on the change in the value of a hypothetical
investment (exclusive of capital changes) over a particular 7-day period, less a
hypothetical charge reflecting deductions from contract values during the period
(the BASE PERIOD), and stated as a percentage of the investment at the start of
the base period (the BASE PERIOD RETURN). The base period return is then
annualized by multiplying by 365/7, with the resulting yield figure carried to
at least the nearest hundredth of one percent. Effective yield assumes that all
dividends received during an annual period have been reinvested. This
compounding effect causes effective yield to be higher than current yield.
Calculation of effective yield begins with the same base period return used in
the calculation of current yield, which is then annualized to reflect weekly
compounding pursuant to the following formula: Effective Yield = {(Base Period
            365/7
Return) + 1)     } - 1

(1)  Standard average annual return reflects past fund performance based on a
     $1,000 hypothetical investment period over the indicated. The performance
     figures reflect the deduction of mortality and expenses and administrative
     charges totaling 1.35%. They also reflect any withdrawal charges that would
     apply if an owner terminated the policy at the end of the period, but
     exclude deductions for the applicable premium tax charges. Surrender
     charges are 8% in year one, declining 1% annually in years one through
     seven, 0% thereafter.
(2)  Inception date of the variable account option represents first trade date.
     Returns for accounts in operation for less than one year are not
     annualized.
(3)  Non-standard returns reflect all historical investment results, less
     mortality and expense and administrative charges totaling 1.35%. The
     calculation assumes the policy is still in force and therefore does not
     take withdrawal charges into consideration.
(4)  Italicized returns are calculated from the inception date through year-end.
(5)  Represents the inception date of the underlying funds. Performance data for
     periods prior to the actual inception of the variable account options is
     hypothetical and based on the performance of the underlying funds. This
     performance data has been adjusted to include all insurance company
     contract charges and management fees of the underlying funds.

PERFORMANCE COMPARISONS

Performance information for an Option may be compared, in reports and
advertising, to: (1) Standard & Poor's Stock Index (S&P 500), Dow Jones
Industrial Averages, (DJIA), Donoghue Money Market Institutional Averages, or
other unmanaged indices generally regarded as representative of the securities
markets; (2) other variable annuity separate accounts or other investment
products tracked by Lipper Analytical Services, Inc. or the Variable Annuity
Research and Data Service, which are widely used independent research firms that
rank mutual funds and other investment companies by overall performance,
investment objectives, and assets; and (3) the Consumer Price Index (measure of
inflation) to assess the real rate of return from an investment in a contract.
Unmanaged indices may assume the reinvestment of dividends but generally do not
reflect deductions for annuity charges, investment management costs, brokerage
costs and other transaction costs that are normally paid when directly investing
in securities.

Each Option may from time to time also include the ranking of its performance
figures relative to such figures for groups of mutual funds categorized by
Lipper Analytical Services (LIPPER) as having the same or similar investment
objectives or by similar services that monitor the performance of mutual funds.
Each Option may also from time to time compare its performance to average mutual
fund performance figures compiled by Lipper in LIPPER PERFORMANCE ANALYSIS.
Advertisements or information furnished to present shareholders or prospective
investors may also include evaluations of an Option published by nationally
recognized ranking services and by financial publications that are nationally
recognized such as BARRON'S, BUSINESS WEEK, CDA TECHNOLOGIES, INC., CHANGING
TIMES, CONSUMER'S DIGEST, DOW JONES INDUSTRIAL AVERAGE, FINANCIAL PLANNING,
FINANCIAL TIMES, FINANCIAL WORLD, FORBES, FORTUNE, GLOBAL INVESTOR, HULBERT'S

PART 4 - DETERMINATION OF ANNUITY UNIT VALUES

The annuity unit value was initially fixed at $1.00 for contracts with assumed
base rates of net investment return of 5% and 3.5% a year, respectively. For
each valuation period thereafter, it is the annuity value for the preceding
valuation period multiplied by the adjusted net investment factor under the
contracts. For each valuation period, the adjusted net investment factor is
equal to the net investment factor reduced for each day in the valuation period
by:

*    .00013366 for a contract with an assumed base rate of net investment return
     of 5% a year; or

*    .00009425 for a contract with an assumed base rate of net investment return
     of 3.5% a year.

Because of this adjustment, the annuity unit value rises and falls depending on
whether the actual rate of net investment return (after charges) is higher or
lower than the assumed base rate.

All certificates have a 5% assumed base rate, except in states where that rate
is not permitted. Annuity payments under contracts with an assumed base rate of
3.5% will at first be smaller than those under contracts with a 5% assumed base
rate. Payments under the 3.5% contracts, however, will rise more rapidly when
unit values are rising, and payments will fall more slowly when unit values are
falling, than those under 5% contracts.

The amounts of variable annuity payments are determined as follows:

   
Payments normally start on the Annuitant's retirement date. The first three
monthly payments are the same and will be based on the amount taken from the
tables in the contract or on our current rates, whichever is more favorable to
the participant. Where the Company's current annuity rates are used,
contributions in the current and five prior participation years will qualify for
the Company's current individual annuity rates applicable to funds derived from
sources outside the Company. The balance of the proceeds will qualify for the
Company's current individual annuity rates for payment of proceeds.
    

The first three monthly payments depend on the assumed base rate of net
investment return and the forms of annuity chosen (and any fixed period). If the
annuity involves a life contingency, the risk class and the age of the
annuitants will affect payments.

   
Payments after the first three months will vary according to the investment
performance of the Variable Account Option or Options selected. After that, each
payment will be calculated by multiplying the number of annuity units credited
by the average annuity unit value for the second calendar month before the due
date of the payment. The number of annuity units credited equals the initial
periodic payment divided by the annuity unit value for the valuation period that
includes the due date of the first annuity payment. The average annuity unit
value is the average of the annuity unit values for the valuation periods ending
in that month. Each business day is considered a valuation period. Days that
aren't considered business days are added to the next business day and
constitute one valuation period. For example, Saturday, Sunday and Monday are
considered to be one valuation period.
    

<PAGE>

ILLUSTRATION OF CHANGES IN ANNUITY UNIT VALUES. To show how we determine
variable annuity payments from month to month, assume that the contract value on
a retirement date is enough to fund an annuity with a monthly payment of $363
and that the annuity unit value for the valuation period that includes the due
date of the first annuity payment is $1.05. The number of annuity units credited
under your contract would be 345.71 (363 divided by 1.05 = 345.71).

If the fourth monthly payment is due in March, and the average annuity unit
value for January was $1.10, the annuity payment for March would be the number
of units (345.71) times the average annuity unit value ($1.10), or $380.28. If
the average annuity unit value was $1.00 in February, the annuity payment for
April would be 345.71 times $1.00, or $345.71.

   
For period certain life annuities and life income annuities, the participant may
not surrender or redeem once annuity payments begin. For period certain life
annuities only, if the payee (or the payee and the other annuitant under a joint
and survivor annuity) dies before the period selected ends, the remaining
payments will go to another named payee who may have the right to redeem the
annuity and get the cash value of future guaranteed payments in a lump sum. The
present value of future guaranteed payments for a period certain is based on the
number of payments left, the assumed base rate of net return, the number of
annuity units and the annuity unit value for the date the Company receives a
written request for lump sum payment of remaining values. Assets held in the
Account at least equal to all statutory reserves required for such Separate
Account.
    

   
PART 5 - TAX FAVORED RETIREMENT PROGRAMS
    

   
The contracts described in the prospectus may be used in connection with certain
tax-favored retirement programs, for groups and individuals. Following are brief
descriptions of various types of qualified plans in connection with which
National Integrity may issue a contract. National Integrity reserves the right
to change its administrative rules, such as minimum contribution amounts, as
needed to comply with the Code as to tax-favored retirement programs.
    

   
TRADITIONAL INDIVIDUAL RETIREMENT ANNUITIES
    

   
Code Section 408(b) permits eligible individuals to contribute to an individual
retirement program known as a Traditional IRA. An individual who receives
compensation and who has not reached age 70-1/2 by the end of the tax year may
establish a Traditional IRA and make contributions up to the deadline for filing
his or her federal income tax return for that year (without extensions).
Traditional IRAs are subject to limitations on the amount that may be
contributed, the persons who may be eligible, and on the time when distributions
may begin. An individual may also rollover amounts distributed from another
Traditional IRA, Roth IRA or another tax-favored retirement program to a
Traditional IRA contract. Your Traditional IRA contract will be issued with a
rider outlining the special terms of your contract that apply to Traditional
IRAs. The Owner will be deemed to have consented to any other amendment unless
the Owner notifies us that he or she does not consent within 30 days from the
date we mail the amendment to the Owner.
    

   
ROTH INDIVIDUAL RETIREMENT ANNUITIES
    

   
Section 408(A) of the Code permits eligible individuals to contribute to an
individual retirement program known as a Roth IRA. An individual who receives
compensation may establish a Roth IRA and make contributions up to the deadline
for filing his or her federal income tax return for that year (without
extensions). Roth IRAs are subject to limitations on the amount that may be
contributed, the persons who are eligible to contribute, and on the time when a
tax-favored distribution may begin. An individual may also rollover amounts
distributed from another Roth IRA or Traditional IRA to a Roth IRA contract.
Your Roth IRA contract will be issued with a rider outlining the special terms
of your contract which apply to Roth IRAs. Any amendment made for the purpose of
complying with provisions of the Code and related regulations may be made
without the consent of the Owner. The Owner will be deemed to have consented to
any other amendment unless the Owner notifies us that he or she does not consent
within 30 days from the date we mail the amendment to the Owner.
    

   
SIMPLE INDIVIDUAL RETIREMENT ANNUITIES
    

   
Currently, we do not issue Individual Retirement Annuities known as a "SIMPLE
IRA" as defined in Section 408(p) of the Code.
    

<PAGE>

   
TAX SHELTERED ANNUITIES
    

   
Section 403(b) of the Code permits the purchase of tax-sheltered annuities (TSA)
by public schools and certain charitable, educational and scientific
organizations described in Section 501(c)(3) of the Code. The contract is not
intended to accept other than employee contributions. Such contributions are
excluded from the gross income of the employee until the employee receives
distributions from the contract. The amount of contributions to the TSA is
limited to certain maximums imposed by Code sections 403(b), 415 and 402(g).
Furthermore, the Code sets forth additional restrictions governing such items as
transferability, distributions and withdrawals. Any employee should obtain
competent tax advice as to the tax treatment and suitability of such an
investment. Your contract will be issued with a rider outlining the special
terms that apply to a TSA.
    

   
SIMPLIFIED EMPLOYEE PENSIONS
    

   
Section 408(k) of the Code allows employers to establish simplified employee
pension plans (SEP-IRAS) for their employees, using the employees' IRAs for such
purposes, if certain criteria are met. Under these plans the employer may,
within specified limits, make deductible contributions on behalf of the
employees to IRAs. Employers intending to use the contract in connection with
such plans should seek competent advice. The SEP-IRA will be issued with a rider
outlining the special terms of the contract.
    

   
CORPORATE AND SELF-EMPLOYED (H.R. 10 AND KEOGH) PENSION AND PROFIT SHARING PLANS
    

   
Sections 401(a) and 403(a) of the Code permit corporate employers to establish
various types of tax-favored retirement plans for employees. The Self-Employed
Individuals' Tax Retirement Act of 1962, as amended, commonly referred to as
"H.R. 10" or "Keogh," permits self-employed individuals also to establish such
tax-favored retirement plans for themselves and their employees. Such retirement
plans may permit the purchase of the contract in order to provide benefits under
the plans. Employers intending to use the contract in connection with these
plans should seek competent advice. The Company can request documentation to
substantiate that a qualified plan exists and is being properly administered.
National Integrity does not administer such plans.
    

   
DEFERRED COMPENSATION PLANS OF STATE AND LOCAL GOVERNMENTS AND TAX-EXEMPT
ORGANIZATIONS
    

   
Section 457 of the Code permits employees of state and local governments and
tax-exempt organizations to defer a portion of their compensation without paying
current taxes. The employees must be participants in an eligible deferred
compensation plan. To the extent the contracts are used in connection with an
eligible plan, employees are considered general creditors of the employer and
the employer as Owner of the contract has the sole right to the proceeds of the
contract. However, Section 457(g), as added by the Small Business and Jobs
Protection Act (SBJPA) of 1996, provides that on and after August 20, 1996, a
plan maintained by an eligible governmental employer must hold all assets and
income of the plan in a trust, custodial account, or annuity contract for the
exclusive benefit of participants and their beneficiaries. Plans in existence on
August 20, 1996, should have established a trust, custodial account, or annuity
contract by January 1, 1999. Loans to employees may be permitted under such
plans; however, a Section 457 plan is not required to allow loans. Contributions
to a contract in connection with an eligible government plan are subject to
limitations. Those who intend to use the contracts in connection with such plans
should seek competent advice. The Company can request documentation to
substantiate that a qualified plan exists and is being properly administered.
National Integrity does not administer such plans.

DISTRIBUTIONS UNDER TAX FAVORED RETIREMENT PROGRAMS
    

   
Distributions from tax-favored plans are subject to certain restrictions. Prior
to the enactment of the 1996 SBJPA, distributions of minimum amounts specified
by the Code must have commenced by April 1 of the calendar year following the
calendar year in which the participant reaches age 70-1/2. The SBJPA provides
participants in qualified plans, with the exception of five-percent owners and
Traditional IRA holders, to begin receiving distributions by April 1 of the
calendar year following the later of either (i) the calendar year in which the
employee reaches age 70-1/2, or (ii) the calendar year in which the employee
retires. Additional distribution rules apply after the participant's death.
Failure to make mandatory distributions may result in the imposition of a 50%
penalty tax on any difference between the required distribution amount and the
amount distributed. Distributions to a participant from all plans (other than
457 plans) in a calendar year that exceed a specific limit under the Code are
generally subject to a 15% penalty tax (in addition to any ordinary income tax)
on the excess portion of the distributions. However, the SBJPA of 1996 has
suspended the excise tax on excess distributions. The provision relating to the
excise tax on excess distributions is effective with respect to distributions
received in 1997, 1998 and 1999.
    

   
The Taxpayer Relief Act of 1997 creating Roth IRAs eliminates mandatory
distribution at age 70 1/2 for Roth IRAs.
    

   
Distributions from a tax-favored plan (not including a Traditional IRA subject
to Code Section 408(a) Roth IRA) to an employee, surviving spouse, or former
spouse who is an alternate payee under a qualified domestic relations order, in
the form of a lump sum settlement or periodic annuity payments for a fixed
period of fewer than 10 years are subject to mandatory income tax withholding of
20% of the taxable amount of the distribution, unless (1) the distributee
directs the transfer of such amounts in cash to another plan or Traditional IRA;
or (2) the payment is a minimum distribution required under the Code. The
taxable amount is the amount of the distribution less the amount allocable to
after-tax contributions. All other types of taxable distributions are subject to
withholding unless the distributee elects not to have withholding apply.
    

   
We are not permitted to make distributions from a contract unless a request has
been made. It is therefore your responsibility to comply with the minimum
distribution rules. You should consult your tax adviser regarding these rules
and their proper application.
    

   
The above description of the federal income tax consequences of the different
types of tax-favored retirement plans which may be funded by the contract is
only a brief summary and is not intended as tax advice. The rules governing the
provisions of plans are extremely complex and often difficult to comprehend.
Anything less than full compliance with all applicable rules, all of which are
subject to change, may have adverse tax consequences. A prospective Owner
considering adoption of a plan and purchase of a contract in connection
therewith should first consult a qualified and competent tax adviser, with
regard to the suitability of the contract as an investment vehicle for the plan.

ITEM 26.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH NATIONAL INTEGRITY
          OR REGISTRANT

   
          National Integrity, the depositor of Separate Account I, is a wholly
owned subsidiary of Integrity Life Insurance Company, an Ohio stock life
insurance corporation. Integrity Life Insurance Company is a wholly owned
subsidiary of Integrity Holdings, Inc., a Delaware corporation which is a

Integrity Holdings, Inc. are owned by ARM Financial Group, Inc. (ARM), a
Delaware corporation which is a financial services company focusing on the
long-term savings and retirement marketplace by providing retail and
institutional products and services throughout the United States. ARM owns 100%

ITEM 28.  INDEMNIFICATION

BY-LAWS OF NATIONAL INTEGRITY.  National Integrity's By-Laws provide, in 
Article VII, as follows:

                                       4
<PAGE>

          7.1 INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND
INCORPORATORS. To the extent permitted by the law of the State of New York and
subject to all applicable requirements thereof:

          (a) any person made or threatened to be made a party to any action or
          proceeding, whether civil or criminal, by reason of the fact that he,
          his testator or intestate, is or was a director, officer, employee or
          incorporator of the Company shall be indemnified by the Company;

          (b) any person made or threatened to be made a party to any action or
          proceeding, whether civil or criminal, by reason of the fact that he,
          his testator or intestate serves or served any other organization in
          any capacity at the request of the Company may be indemnified by the
          Company; and

          (c) the related expenses of any such person in any other of said
          categories may be advanced by the Company.

BY-LAWS OF ARM SECURITIES. ARM Securities' By-Laws provide, in Sections 4.01 and
4.02, as follows:

          SECTION 4.01  INDEMNIFICATION. The Corporation shall indemnify its
officers and directors for such expenses and liabilities, in such manner, under
such circumstances, and to such extent, as required or permitted by Minnesota
Statutes, Section 302A.521, as amended from time to time, or as required or
permitted by other provisions of law.


          SECTION 4.02  INSURANCE. The Corporation may purchase and maintain
insurance on behalf of any person in such person's official capacity against any
liability asserted against and incurred by such person in or arising from that
capacity, whether or not the Corporation would otherwise be required to
indemnify the person against the liability. 

AGREEMENTS. National Integrity and ARM Securities, including each director,
officer, and controlling person of National Integrity and ARM Securities, are
entitled to indemnification against certain liabilities as described in Sections
5.2, 5.3 and 5.5 of the Selling Agreement and Section 9 of the Form of Variable
Contract Selling Agreement incorporated as Exhibit 3(a) to this Registration
Statement. Those sections are incorporated by reference into this response. In
addition, National Integrity and ARM Securities, including each director,
officer and controlling person of National Integrity and ARM Securities, are
entitled to indemnification against certain liabilities as described in Article
VIII of the Participation Agreements incorporated as Exhibits 8(a) and 8(b) to
this Registration Statement. That article is incorporated by reference into this
response. Certain officers and directors of National Integrity are officers and
directors of ARM Securities (see Item 25 and Item 29 of this Part C).

INSURANCE. The directors and officers of National Integrity and ARM Securities
are insured under a policy, issued by National Union. The total annual limit on
such policy is $10 million, and the policy insures the officers and directors
against certain liabilities arising out of their conduct in such capacities.

   
UNDERTAKING. Insofar as indemnification for liability arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

          (a)    to file a post-effective amendment to this registration
                 statement as frequently as is necessary to ensure that the
                 audited financial statements in the registration statement are
                 never more than 16 months old for so long as payments under the
                 variable annuity contracts may be accepted;

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

          (c)    to deliver any Statement of Additional Information and any
