Summary

The sections in this Summary provide you with a concise discussion of the major
topics covered in this prospectus. Each section of the Summary is discussed in
greater detail in the main body of the prospectus at corresponding section
headings. Please read the full prospectus carefully.

THE ANNUITY CONTRACT

The Vanguard Variable Annuity Plan Contract is a flexible-premium multi-funded
variable annuity offered by AUSA Life Insurance Company, Inc. (the "Company").
The Contract provides a means of investing on a tax-deferred basis in thirteen
portfolios of Vanguard Variable Insurance Fund ("Portfolios").

Who Should Invest

The Contract is intended for long-term investors who want tax-deferred
accumulations of funds, generally for retirement but also for other long-term
purposes. 

The Contract provides benefits in two distinct phases: accumulation and income.

The Accumulation Phase

During the Accumulation Phase, you choose to allocate your investment in the
Contract among the thirteen Vanguard Portfolios available under the Contract.
You can contribute additional dollars to the Contract and you can take
withdrawals from the Contract during the Accumulation Phase. The value of your
investment depends on the investment performance of the Portfolios you choose.
Your earnings are generally not taxed during this phase unless you withdraw
them.

The Income Phase

During the Income Phase, you can receive regular annuity payments on a fixed or
variable basis and for various periods of time depending on your need for income
and the choices available under the Contract. See Annuity Payments, page 12, for
more information about Annuity Payment Options.

Vanguard Variable Insurance Fund

The Portfolios available for investment under the Contract are portfolios of
Vanguard Variable Insurance Fund (the "Fund"), an open-end diversified
investment company. The Fund is a member of The Vanguard Group of Investment
Companies, a family of more than 30 investment companies with more than 100
distinct investment portfolios holding assets worth more than $450 billion.

ANNUITY PAYMENTS

During the Income Phase, you receive regular annuity payments under a wide range
of Annuity Payment Options. The Contract allows you to receive an income
guaranteed for as long as you live or until the second of two people dies. You
may also choose to receive a guaranteed number of payments over a number of
years. Most Annuity Payment Options are available on either a variable basis
(where the amount of the payment rises or falls depending on the investment
performance of the Portfolios you have chosen) or a fixed basis (where the
payment amount is guaranteed).
<PAGE>
 
                                                                               5

PURCHASE

You can buy the Contract with a minimum investment of $5,000 under most
circumstances. You can add $250 or more at any time during the Accumulation
Phase. The total of all your Purchase Payments in the Contract may not exceed
$1,000,000 without prior approval from the Company.

INVESTMENT OPTIONS

You can allocate your Purchase Payments to one or more of the following
Portfolios described in the Fund prospectus:

Managed by Vanguard's Fixed Income Group 
Money Market Portfolio 
High-Grade Bond Portfolio 
Short-Term Corporate Portfolio

Managed by Vanguard's Core Management Group 
Equity Index Portfolio 
Mid-Cap Index Portfolio 
REIT Index Portfolio

Managed by Wellington Management Company, LLP
High Yield Bond Portfolio 
Balanced Portfolio

Managed by Newell Associates 
Equity Income Portfolio

Managed by Barrow, Hanley, Mewhinney & Strauss, Inc.
Diversified Value Portfolio

Managed by Lincoln Capital Management Company 
Growth Portfolio

Managed by Granahan Investment Management 
Small Company Growth Portfolio

Managed by Schroder Capital Management International, Inc.
International Portfolio

You can make or lose money in any of these Portfolios depending on their
investment performance.

EXPENSES

There are no sales charges or sales loads associated with the Contract.

   The Company will deduct a daily charge corresponding to an annual charge of
0.10% of the net asset value of the Separate Account as an Administrative
Expense Charge and an annual charge of 0.27% for the mortality and expense risks
assumed by the Company. For Contracts valued at less than $25,000, there is also
a $25 Annual Contract Maintenance Fee.
<PAGE>
 
6

Summary (continued)

You will also pay Fund Operating Expenses, which currently range from 0.20% to
0.48% annually of the average daily value of the Portfolios.

TAXES

In general, you are not taxed on earnings on your investment in the Contract
until you withdraw them or receive Annuity Payments. Earnings are taxed as
ordinary income. During the Accumulation Phase, for tax purposes withdrawals are
taken from earnings first, then from your investment in the Contract. If you
receive money from the Contract before age 59 1/2, you may have to pay a 10%
federal penalty tax on the earnings portion received. During the Income Phase,
payments come partially from earnings, partially from your investment. You are
taxed only on the earnings portion of each Annuity Payment.

ACCESS TO YOUR MONEY

You can take money out of your Contract at any time during the Accumulation
Phase without incurring a withdrawal charge. Each withdrawal you make must be at
least $250. You may have to pay income tax and a tax penalty on any money you
take out.

PERFORMANCE

The investment performance of the Portfolios you choose directly affects the
value of your Contract. You bear all investment risk (including the possible
loss of principal), and investment results are not guaranteed. 

  From time to time, the Company may advertise the investment performance of the
Portfolios. In doing so, it will use standardized methods prescribed by the
Securities and Exchange Commission, as well as certain non-standardized methods.
  
  Past performance does not indicate or predict future performance.

DEATH BENEFIT

If the Annuitant dies during the Accumulation Phase, the Beneficiary will
receive the Death Benefit. The Death Benefit is the greater of the then-current
Accumulated Value of the Contract or the sum of all Purchase Payments (less any
partial withdrawals). The Beneficiary may elect to receive these amounts as a
lump sum or as Annuity Payments.

   Federal tax law requires that if a Contract Owner is a natural person and
dies before the Annuity Date, then the entire value of the Contract must be
distributed within five years of the date of death of the Contract Owner.
Special rules may apply to a surviving spouse. If the Contract Owner is not a
natural person, the death of the primary Annuitant triggers the same
distribution requirement.

OTHER INFORMATION 

Free Look Periods

There are two different Free Look Periods. If the Contract is not a replacement
of an existing annuity contract or life insurance or endowment policy, the
Contract provides for a Free Look Period of 20 days after the Contract Owner
receives the Contract plus 5 days for mailing. If the Contract is a replacement
of an existing annuity contract or life insurance or endowment policy, a Free
Look Period exists for 60 days after the Contract Owner receives the Contract
plus 5 days for mailing. If you cancel your Contract during the applicable Free
Look Period, the Company will return at least the amount of your Purchase
Payments received under the Contract to date.

Reinstatements

If you ask the Company to reinstate a Contract exchanged under Internal Revenue
Code Section 1035 or a Contract whose funds were transferred via a
trustee-to-trustee under the Internal Revenue Code, the Company will require the
Contract Owner to replace the same total amount of money in the applicable
Subaccounts as was taken from them to effect the transfer.

   The Annual Contract Maintenance Fee is reflected in this example as a
percentage equal to the total amount of fees collected during a year divided by
the total average net assets of the Portfolios during the same year. The fee is
assumed to remain the same in each year of the above periods. The fee is
prorated to reflect only the remaining portion of the calendar year of purchase.
Thereafter, the fee is deducted on the last business day of the year for the
following year, on a pro rata basis, from each of the Portfolios you have
chosen. For a complete discussion of Contract costs and expenses, see Expenses,
page 22.

   You should not consider this example to be a representation of past or future
expenses or performance. Actual expenses may be higher or lower than those
shown, subject to the guarantees in the Contract.

                                                                              11

The Annuity Contract

The Vanguard Variable Annuity Plan Contract is a flexible-premium multi-funded
variable annuity offered by AUSA Life Insurance Company, Inc. (the "Company").
The Contract provides a means of investing on a tax-deferred basis in various
portfolios (the "Portfolios") offered by Vanguard Variable Insurance Fund. You
may purchase a Contract using after-tax dollars (a Non-Qualified Contract), or
you may purchase a Qualified Contract by "rolling over" funds from another
individual retirement annuity or from a qualified plan.

Who Should Invest

The Contract is intended for long-term investors who want tax-deferred
accumulation of funds, generally for retirement but also for other long-term
investment purposes. The tax-deferred feature of the Contract is most attractive
to investors in high federal and state marginal tax brackets who have exhausted
other avenues of tax deferral, such as pre-tax contributions to
employer-sponsored retirement or savings plans.

About the Contract

The Vanguard Variable Annuity Plan Contract is a contract between you, the
Contract Owner, and the Company, the issuer of the Contract. 
   The Contract provides benefits in two distinct phases: accumulation and
income.

Accumulation Phase

The Accumulation Phase starts when you purchase your Contract and ends
immediately before the Annuity Date, when the Income Phase starts. During the
Accumulation Phase, you choose to allocate your investment in the Contract among
the thirteen available Portfolios. The Contract is a variable annuity because
the value of your investment in the Portfolios can go up or down depending on
the investment performance of the Portfolios you choose. The Contract is a
flexible-premium annuity because you can make additional investments of at least
$250 until the Income Phase begins. During this phase, you are generally not
taxed on earnings from amounts invested unless you withdraw them.

   Other benefits available during the Accumulation Phase include the ability
to:

 .  Make exchanges among your Portfolio choices at no charge and without current
   tax consequences. (See Exchanges Among the Portfolios, page 21.)

 .  Withdraw all or part of your money with no surrender penalty charged by the
   Company, although you may incur income taxes and a 10% penalty tax prior to
   age 59 1/2. (See Full and Partial Withdrawals, page 28.)

Income Phase

During the Income Phase, you receive regular annuity payments. The amount of
these payments is based in part on the amount of money accumulated under your
Contract (its Accumulated Value) and the Annuity Payment Option you select. The
Annuity Payment Options are explained at Annuity Payments, page 12.

   At your election, payments can be either variable or fixed. If variable, the
payments rise or fall depending on the investment performance of the Portfolios
you choose. If fixed, the payment amounts are guaranteed.

   Annuity payments are available in a wide variety of options, including
payments over a specified period or for life (for either a single life or joint
lives), with or without a guaranteed number of payments.

The Annuity Contract (continued)

The Separate Account

When you purchase a Contract, your money is deposited into the Company's
Separate Account B. The Separate Account contains a number of Subaccounts that
invest exclusively in shares of the corresponding Portfolios. The investment
performance of each Subaccount is linked directly to the investment performance
of one of the Portfolios. Assets in the Separate Account belong to the Company
but are accounted for separately from the Company's other assets and can be used
only to satisfy its obligations to Contract Owners.

Vanguard Variable Insurance Fund

The Portfolios available for investment under the Contract are portfolios of
Vanguard Variable Insurance Fund, an open-end diversified investment company
intended exclusively as an investment vehicle for variable annuity and variable
life insurance contracts offered by insurance companies. The Fund is a member of
The Vanguard Group of Investment Companies, a family of more than 30 investment
companies with more than 100 distinct investment portfolios holding assets worth
more than $450 billion. Through their jointly owned subsidiary, The Vanguard
Group, Inc., Vanguard Variable Insurance Fund and the other funds in the group
obtain at cost virtually all of their corporate management, administrative,
shareholder accounting, and distribution services.

Annuity Payments

During the Income Phase, you receive regular annuity payments under a wide range
of Annuity Payment Options.

Starting the Income Phase

As Contract Owner, you exercise control over when the Income Phase begins by
specifying an Annuity Date on the Enrollment Form when you purchase the
Contract. The Annuity Date is the date on which annuity payments begin and is
always the first day of the month you specify. You may also change the Annuity
Date at any time in writing, as long as the Annuitant or Joint Annuitant is
living and the Company receives the request at least 30 days before the
then-scheduled Annuity Date. Any Annuity Date you request must be at least 30
days from the day the Company receives written notice of it. The latest possible
Annuity Date the Company will accept without prior approval is the first day of
the month after the Annuitant's 85(th) birthday for Contracts issued before
October 1, 1998 or the Annuitant's 90(th) birthday for Contracts issued on or
after October 1, 1998. 

   If you do not specify an Annuity Date, either on the Enrollment Form or by
written request, your Annuity Date will be the first day of the month after ten
full years from the date of your Contract or the first day of the month after
the Annuitant's 65(th) birthday, whichever is later. 

   The Annuity Date for Qualified Contracts may also be controlled by
endorsements, the plan, or applicable law.

Annuity Payment Options

The income you take from the Contract during the Income Phase can take several
different forms, depending on your particular needs. Except for the Designated
Period Annuity Option listed below, the Annuity Payment Options listed below are
available on either a variable basis or a fixed basis. 

   If available on a variable basis, the Annuity Payment Options provide
payments that, after the initial payment, will go up or down depending on the
investment performance of the Portfolios you choose.
<PAGE>
 
                                                                              13

If available on a fixed basis, the Annuity Payment Options provide payments in
an amount that does not change. If you choose a fixed Annuity Payment Option,
the Company will move your investment out of the Portfolios and into the general
account of the Company. 

 .  Life Annuity - Monthly Annuity Payments are paid for the life of an
   Annuitant, ending with the last payment before the Annuitant dies.

 .  Joint and Last Survivor Annuity - Monthly Annuity Payments are paid for as
   long as at least one of two named Annuitants is living, ending with the last
   payment before the surviving Annuitant dies.

 .  Life Annuity With Period Certain - Monthly Annuity Payments are paid for as
   long as the Annuitant lives, with payments guaranteed to be made for a period
   of at least 10 years, 15 years, or 20 years, as elected. If the Annuitant
   dies before the period certain ends, the Company will make any remaining
   payments to the Beneficiary.

 .  Installment or Unit Refund Life Annuity - Available as either a fixed
   (Installment Refund) or variable (Unit Refund) Annuity Payment Option.
   Monthly Annuity Payments are paid for the life of an Annuitant, with a period
   certain determined by dividing the Accumulated Value by the first Annuity
   Payment. If the Annuitant dies before the period certain ends, the Company
   will make any remaining payments to the Beneficiary.

 .  Designated Period Annuity - Available only on a fixed basis. Monthly Annuity
   Payments are paid for a specified period, which may be from 10 to 30 years.

Calculating Annuity Payments 

Fixed Annuity Payments. Each fixed Annuity Payment is guaranteed to be at least
the amount shown in the Contract's Annuity Tables corresponding to the Annuity
Payment Option selected.

Variable Annuity Payments. To calculate variable Annuity Payments, the Company
determines the amount of the first variable Annuity Payment. The first variable
Annuity Payment will equal the amount shown in the applicable Annuity Table in
the Contract. This amount depends on the Accumulated Value of your Contract on
the Annuity Date, the sex and age of the Annuitant (and Joint Annuitant where
there is one), the Annuity Payment Option selected, and any applicable Premium
Taxes. Subsequent variable Annuity Payments depend on the investment experience
of the Portfolios chosen. If the actual net investment experience of the
Portfolios chosen exactly equals the Assumed Interest Rate of 4%, then the
variable Annuity Payments will not change in amount. If the actual net
investment experience of the Portfolios chosen is greater than the Assumed
Interest Rate of 4%, then the variable Annuity Payments will increase. On the
other hand, they will decrease if the actual experience is lower. The Statement
of Additional Information contains a more detailed description of the method of
calculating variable Annuity Payments.

Impact of Annuitant's Age on Annuity Payments. For either fixed or variable
Annuity Payments involving life income, the actual ages of the Annuitant and
Joint Annuitant will affect the amount of each payment. Since payments based on
the lives of older Annuitants and Joint Annuitants are expected to be fewer in
number, the amount of each Annuity Payment will be greater.
<PAGE>
 
14

Annuity Payments (continued)

Impact of Annuitant's Sex on Annuity Payments. For either fixed or variable
Annuity Payments involving life income, the sex of the Annuitant and Joint
Annuitant will affect the amount of each payment. Since payments based on the
lives of male Annuitants and Joint Annuitants are expected to be fewer in
number, the amount of each Annuity Payment will be greater than for female
Annuitants and Joint Annuitants.

Impact of Length of Payment Periods on Annuity Payments. The value of all
payments, both fixed and variable, will be greater for shorter guaranteed
periods than for longer guaranteed periods, and greater for single-life
annuities than for joint and survivor annuities, because they are expected to be
made for a shorter period.

A FEW THINGS TO KEEP IN MIND REGARDING ANNUITY PAYMENTS

 .  If an Annuity Payment Option is not selected, the Company will assume that
   you chose the Life Annuity With Period Certain option (with 10 years of
   payments guaranteed) on a variable basis.

 .  The minimum payment is $100. If during the Accumulation Phase your
   Accumulated Value falls below $5,000 for Contracts issued before October 1,
   1998 or $2,000 for Contracts issued on or after October 1, 1998, the Company
   reserves the right to pay that amount to you in a lump sum.

 .  From time to time, the Company may require proof that the Annuitant, Joint
   Annuitant, or Contract Owner is living.

 .  If someone has assigned ownership of a Contract to you, or if a non-natural
   person (e.g., a corporation) owns a Contract, you may not start the Income
   Phase of the Contract without the Company's consent.

 .  At the time the Company calculates your fixed Annuity Payments, the Company
   may offer more favorable rates than those guaranteed in the Annuity Tables
   found in the Contract.

 .  Once Annuity Payments begin, you may not select a different Annuity Payment
   Option. Nor may you cancel an Annuity Payment Option after Annuity Payments
   have begun.

 .  If you have selected a variable Annuity Payment Option, you may change the
   Portfolios funding the variable Annuity Payments by written request. However,
   because excessive exchanges can potentially disrupt the management of the
   Portfolios and increase transaction costs, exchange activity is limited to
   two substantive "round trips" through the Portfolios (except the Money Market
   Portfolio) during any 12-month period. A "round trip" is a redemption from a
   Portfolio followed by a purchase back into the Portfolio within 30 days.
   Also, "round trip" covers transactions accomplished by any combination of
   methods, including transactions conducted by check, wire, or exchange to or
   from another Vanguard fund. "Substantive" means a dollar amount that The
   Vanguard Group, Inc. determines, in its sole discretion, could adversely
   affect management of the Fund.

 .  You may select an Annuity Payment Option and allocate a portion of the value
   of your Contract to a fixed version of that Annuity Payment Option and a
   portion to a variable version of that Annuity Payment Option (assuming the
   Annuity Payment Option is available on both a fixed and variable basis). You
   may not select more than one Annuity Payment Option.

 .  If you choose an Annuity Payment Option and the postal or other delivery
   service is unable to deliver checks to the Payee's address of record, no
   interest will accrue on amounts represented by uncashed Annuity Payment
   checks. It is the Payee's responsibility to keep the Company informed of the
   Payee's most current address of record.

Purchase

Enrollment and Issuance of Contracts

Contract Issuance. To invest in the Vanguard Variable Annuity Plan Contract, you
should send a completed Enrollment Form, a signed and completed Definition of
Replacement form, and your Initial Purchase Payment to the Vanguard Variable
Annuity Plan Center. The Company will issue a Contract only if the Annuitant and
Joint Annuitant are 75 years of age or less.

   If the Enrollment Form and the Definition of Replacement form are received in
good order, the Company will issue the Contract and will credit the Initial
Purchase Payment within two Business Days after receipt. A Business Day is any
day that the New York Stock Exchange is open for trading. 

   If the Company cannot credit the Initial Purchase Payment because the
Enrollment Form or the Definition of Replacement form is incomplete, the Company
will contact the applicant in writing, explain the reason for the delay, and
refund the Initial Purchase Payment within five Business Days unless the
applicant consents to the Company's retaining the Initial Purchase Payment and
crediting it as soon as the necessary requirements are fulfilled.

   In order to prevent lengthy processing delays caused by the clearing of
foreign checks, the Company will accept only those foreign checks that are drawn
in U.S. dollars and are issued by a foreign bank with a U.S. correspondent bank.

   You may purchase a Qualified Contract only in connection with a "rollover" of
funds from another qualified plan or individual retirement annuity. Qualified
Contracts contain certain other restrictive provisions limiting the timing of
payments to and distributions from the Qualified Contract. (See QUALIFIED
INDIVIDUAL RETIREMENT ANNUITIES, page 28.)

                                  DEFINITION

                              Qualified Contract

When the term "Qualified Contract" is used in this prospectus we mean a Contract
that qualifies as an individual retirement annuity under Section 408(b) of the
Internal Revenue Code. There are other types of qualified annuity contracts
defined under different Internal Revenue Code sections, but we are not referring
to those in this prospectus.

Purchase Payments

A Purchase Payment is any amount you use to buy or add to the Contract. A
Purchase Payment may be reduced by any applicable Premium Tax or an initial
Annual Contract Maintenance Fee. In that case, the resulting amount is called a
Net Purchase Payment.
<PAGE>

Purchase (continued)

A FEW THINGS TO KEEP IN MIND REGARDING PURCHASE PAYMENTS 

 .  The minimum Initial Purchase Payment for a Contract is $5,000.

 .  The Company will not accept third-party checks for Purchase Payments.

 .  You may make additional Purchase Payments at any time during the Accumulation
   Phase and while the Annuitant or Joint Annuitant, if applicable, is living.
   Additional Purchase Payments must be at least $250.

 .  Additional Purchase Payments received before the close of the New York Stock
   Exchange (usually 4 p.m. Eastern time) are credited to the Contract's
   Accumulated Value as of the close of business that same day.

 .  The minimum amount that you can allocate to any one Portfolio is $1,000.

 .  The total of all Purchase Payments may not exceed $1,000,000 without prior
   approval from the Company.

The date on which the Initial Purchase Payment is credited to the Contract value
is called the Contract Date.

                                  DEFINITION

                                  Premium Tax

A Premium Tax is a regulatory tax some states assess on the Purchase Payments
made into a Contract. If the Company should have to pay any Premium Tax, it will
be deducted from each Purchase Payment or from the Accumulated Value as the
Company incurs the tax. Currently, New York does not impose a Premium Tax.

Annuity Express(TM)

The Annuity Express service allows you to make additional Purchase Payments by
transferring funds automatically from your checking or statement savings account
(not passbook savings account) to one or more Portfolios on a monthly,
quarterly, semi-annual, or annual basis. You may add to existing Portfolios
provided you have a minimum balance of $1,000. The minimum automatic purchase is
$50; the maximum is $100,000.

Section 1035 Exchanges

Under Section 1035 of the Internal Revenue Code, you may exchange the assets of
an existing annuity contract or life insurance or endowment policy to the
Vanguard Variable Annuity Plan Contract without any current tax consequences. To
make a "1035 Exchange," complete a 1035 Exchange form and mail it along with
your signed and completed Enrollment Form, Definition of Replacement form,
Important Notice Regarding Replacement or Change of Life Insurance Policies or
- ---------
Annuity Contracts, and your current contract, to the Vanguard Variable Annuity
Plan Center. 

   To accommodate owners of Vanguard Variable Annuity Plan Contracts, under
certain conditions the Company will allow for the consolidation of two or more
Vanguard Variable Annuity Plan Contracts into one Contract. In order to provide
Contract Owners with consolidated account reporting, the Company will accept
these exchanges on a case-by-case basis. If applicable, you will be responsible
for only one Annual Contract Maintenance Fee. Under no circumstances will the
Company allow the exchange of an existing Vanguard Variable Annuity Plan
Contract for an identical new Vanguard Variable Annuity Plan Contract.

   Because special rules and procedures apply to 1035 Exchanges, particularly if
the Contract being exchanged was issued prior to August 14, 1982, you should
consult a tax adviser before making a 1035 Exchange.

   Please note that any outstanding loans you may have on a contract you wish to
exchange may create a current tax consequence. For this reason we encourage you
to settle any outstanding loans with your current insurance company before
initiating a 1035 Exchange into a Vanguard Variable Annuity Plan Contract.

Allocation of Purchase Payments

You specify on the Enrollment Form what portion of your Purchase Payments you
want to be allocated among which Portfolios. You may allocate your Purchase
Payments to one or more Portfolios. All allocations you make must be in
whole-number percentages and must be at least 10% of your Contract's Accumulated
Value and $1,000. Your initial Net Purchase Payment will be immediately
allocated among the Portfolios in the percentages you specified on your
Enrollment Form without waiting for the Free Look Period to pass.

   Should your investment goals change, you may change the allocation
percentages for additional Net Purchase Payments by sending written notice to
the Vanguard Variable Annuity Plan Center. The change will take effect on the
date the Company receives your written notice.

Purchase (continued)

                        WHAT'S MY CONTRACT WORTH TODAY?

                               Accumulated Value

The Accumulated Value of your Contract is the value of all amounts accumulated
under the Contract during the Accumulation Phase (similar to the current market
value of a mutual fund account). When the Contract is opened, the Accumulated
Value is equal to your initial Net Purchase Payment. On any Business Day
thereafter, the Accumulated Value equals the Accumulated Value from the previous
Business Day, plus:

 .  Any additional Net Purchase Payments credited

 .  Any increase in the Accumulated Value due to investment results of the
   Portfolio(s) you selected

minus: 

 .  Any decrease in the Accumulated Value due to investment results of the
   Portfolio(s) you selected

 .  The daily Mortality and Expense Risk Charge

 .  The daily Administrative Expense Charge

 .  The Annual Contract Maintenance Fee, if applicable

 .  Any withdrawals 

 .  Any Premium Taxes that occur during the Valuation Period.

The Valuation Period is any period between two successive Business Days
beginning at the close of business of the first Business Day and ending at the
close of business of the next Business Day.

   You should expect the Accumulated Value of your Contract to change from
Valuation Period to Valuation Period, reflecting the investment experience of
the Portfolios you have selected as well as the daily deduction of charges.

An Accumulation Unit is a measure of your ownership interest in the Contract
during the Accumulation Phase. When you allocate your Net Purchase Payments to a
selected Portfolio, the Company will credit a certain number of Accumulation
Units to your Contract. The Company determines the number of Accumulation Units
it credits by dividing the dollar amount you have allocated to a Portfolio by
the Accumulation Unit Value for that Portfolio as of the end of the Valuation
Period in which the payment is received. Each Portfolio has its own Accumulation
Unit Value (similar to the share price (net asset value) of a mutual fund). The
Accumulation Unit Value varies each Valuation Period with the net rate of return
of the Portfolio. The net rate of return reflects the performance of the
Portfolio for the Valuation Period and is net of asset charges to the Portfolio.
Per Portfolio, the Accumulated Value equals the number of Accumulation Units
multiplied by the Accumulation Unit Value for that Portfolio. 

   All dividends and capital gains earned will be reinvested and reflected in
the Accumulation Unit Value. Only in this way can these earnings remain
tax-deferred.

Investment Options

Vanguard Variable Insurance Fund

The Vanguard Variable Annuity Plan Contract offers you a means of investing in
thirteen Portfolios of Vanguard Variable Insurance Fund. A brief description of
each Portfolio is given below. For more detailed information regarding the
Portfolios, you should read the prospectus for Vanguard Variable Insurance Fund
that accompanies the Contract prospectus.

   The general public may invest in the Portfolios of Vanguard Variable
Insurance Fund only through certain insurance contracts. The investment
objectives and policies of the Portfolios may be similar to those of publicly
available Vanguard funds or portfolios. You should not expect that the
investment results of any publicly available Vanguard funds or portfolios will
be comparable to those of the Portfolios.

 .  The Money Market Portfolio seeks to provide current income consistent with
   the preservation of capital and liquidity. The Portfolio also seeks to
   maintain a stable net asset value of $1 per share. The Portfolio invests
   primarily in high-quality money market instruments issued by financial
   institutions, non-financial corporations, the U.S. government, state and
   municipal governments and their agencies or instrumentalities, as well as
   repurchase agreements collateralized by such securities. The Portfolio also
   invests in Eurodollar obligations (dollar-denominated obligations issued
   outside the U.S. by foreign banks or foreign branches of domestic banks) and
   Yankee obligations (dollar-denominated obligations issued in the U.S. by
   foreign banks). An investment in the Portfolio is not insured or guaranteed
   by the FDIC or any other government agency. Although the Portfolio seeks to
   preserve the value of your investment at $1 per share, it is possible to lose
   money by investing in the Portfolio. Vanguard's Fixed Income Group serves as
   this Portfolio's investment adviser.

 .  The High-Grade Bond Portfolio seeks to parallel the investment results of the
   Lehman Brothers Aggregate Bond Index. The Portfolio invests primarily in a
   diversified portfolio of U.S. government and corporate bonds and
   mortgage-backed securities. Vanguard's Fixed Income Group serves as this
   Portfolio's investment adviser.

 .  The High Yield Bond Portfolio seeks to provide a high level of current income
   by investing in lower-rated debt securities, which may be regarded as having
   speculative characteristics and are commonly referred to as "junk bonds."
   Under normal circumstances, at least 80% of the Portfolio's assets will be
   invested in high-yield corporate debt obligations rated at least B by Moody's
   Investors Service, Inc. or Standard & Poor's Corporation or, if unrated, of
   comparable quality as determined by the Portfolio's adviser, Wellington
   Management Company.

 .  The Short-Term Corporate Portfolio seeks to provide a high level of income by
   investing primarily in high-quality, short-term bonds issued by corporations.
   Vanguard's Fixed Income Group serves as this Portfolio's investment adviser.

 .  The Balanced Portfolio seeks the conservation of principal, while providing
   moderate income, and moderate long-term growth of capital and income. The
   Portfolio invests in a diversified portfolio of common stocks and bonds, with
   common stocks expected to represent 60% to 70% of the Portfolio's total
   assets and bonds to represent 30% to 40%. Wellington Management Company
   serves as this Portfolio's investment adviser.
<PAGE>

Investment Options (continued)

 .  The Diversified Value Portfolio seeks to provide long-term growth of capital
   and a moderate level of dividend income by investing primarily in common
   stocks of large and medium-sized companies whose stocks the adviser considers
   to be undervalued and out of favor with investors. Such "value" stocks
   typically have above-average dividend yields and/or below-average prices in
   relation to such financial measures as earnings, book value, and cash flow.
   Barrow, Hanley, Mewhinney & Strauss, Inc. serves as this Portfolio's
   investment adviser.

 .  The Equity Income Portfolio seeks to provide a high level of current income
   by investing principally in dividend-paying equity securities. Newell
   Associates serves as this Portfolio's investment adviser.

 .  The Equity Index Portfolio seeks to provide long-term growth of capital by
   matching the performance of the Standard & Poor's 500 Composite Stock Price
   Index ("S&P 500"), which contains the stocks of 500 of the largest domestic
   companies. Vanguard's Core Management Group serves as this Portfolio's
   investment adviser.

 .  The Growth Portfolio seeks to provide long-term capital appreciation. The
   Portfolio invests primarily in equity securities of seasoned U.S. companies
   with above-average prospects for growth. Lincoln Capital Management Company
   serves as this Portfolio's investment adviser.

 .  The Mid-Cap Index Portfolio seeks to provide long-term growth of capital by
   attempting to match the performance of the Standard & Poor's MidCap 400 Index
   ("S&P MidCap 400"), which is made up of stocks of medium-sized companies.
   Vanguard's Core Management Group serves as this Portfolio's investment
   adviser.

 .  The REIT Index Portfolio seeks to provide a high level of income and moderate
   long-term growth of capital by investing in stocks of real estate investment
   trusts ("REITs"), which own office buildings, hotels, shopping centers, and
   other properties. The Portfolio seeks to match the performance of the Morgan
   Stanley REIT Index, a benchmark of U.S. property trusts. Vanguard's Core
   Management Group serves as this Portfolio's investment adviser.

 .  The Small Company Growth Portfolio seeks to provide long-term growth in
   capital by investing primarily in equity securities of small companies deemed
   to have favorable prospects for growth. These securities are primarily common
   stocks but may also include securities convertible into common stock.
   Granahan Investment Management serves as this Portfolio's investment adviser.

 .  The International Portfolio seeks to provide long-term capital appreciation.
   The Portfolio invests primarily in equity securities of companies based
   outside the United States. Schroder Capital Management International, Inc.
   serves as this Portfolio's investment adviser.

   There is no assurance that a Portfolio will achieve its stated objective.

   Additional information regarding the investment objectives and policies of
the Portfolios and the investment advisory services can be found in the current
Fund prospectus accompanying this prospectus.

Exchanges Among the Portfolios

Should your investment goals change, you may exchange money among the Portfolios
of the Fund at no cost, subject to the following conditions: 

 .  You may make requests for exchanges in writing. The Company will process
   requests it receives prior to the close of the New York Stock Exchange
   (generally 4 p.m. Eastern time) at the close of business that same day.
   Requests received after the close of the New York Stock Exchange are
   processed the next Business Day.

 .  The minimum amount you may exchange from a Portfolio is $250 (unless the
   Accumulated Value in a Portfolio is less than $250).

 .  The $1,000 minimum balance requirement per Portfolio must be satisfied at all
   times.

 .  The Company does not charge a fee for exchanges among the Portfolios.

                            LIMITATIONS ON EXCHANGES

Because excessive exchanges can disrupt management of the Fund and increase the
Fund's costs for all Contract Owners, the Fund limits exchanges as follows:

 .  You may make no more than two substantive "round trips" through a Portfolio
   (not including the Money Market Portfolio) during any 12-month period.

 .  The Fund and the Company may refuse an exchange at any time, for any reason.

 .  The Company may revoke a Contract Owner's telephone exchange privilege at any
   time, for any reason.

   A "round trip" is a redemption from a Portfolio followed by a purchase back
into the Portfolio within 30 days. Also, "round trip" covers transactions
accomplished by any combination of methods, including transactions conducted by
check, wire, or exchange to or from another Vanguard fund. "Substantive" means a
dollar amount that The Vanguard Group, Inc. determines, in its sole discretion,
could adversely affect management of the Fund.

Automatic Exchange Service

With the Automatic Exchange Service you can move money automatically among the
Portfolios of the Fund. You can exchange fixed dollar amounts or percentages of
your Portfolio balance into the other Portfolios offered under the Contract on
either a monthly, quarterly, semiannual, or annual basis (provided the $1,000
minimum balance requirement has been met in the Portfolios to which you are
moving money). 

   The minimum amount you may exchange is $250.

                             Dollar-Cost Averaging

Using the Automatic Exchange Service, you can establish exchanges at regular
intervals in a plan of investing often referred to as "dollar-cost averaging,"
moving money, for example, from the Money Market Portfolio into a stock or bond
Portfolio. The main objective of Dollar-Cost Averaging is to shield your
investment from short-term price fluctuations. Since the same dollar amount is
transferred to other Portfolios each month, more Accumulation Units are credited
to a Portfolio if the value per Accumulation Unit is low, while fewer
Accumulation Units are credited if the value per Accumulation Unit is high.
Therefore, it is possible to achieve a lower average cost per Accumulation Unit
over the long term if the Accumulation Unit Value declines over that period.
This plan of investing allows investors to take advantage of market fluctuations
but does not assure a profit or protect against a loss in declining markets.

   To take advantage of the Automatic Exchange Service, complete a Vanguard
Variable Annuity Plan Automatic Exchange Service Application Form or send a
letter of instruction to the Vanguard Variable Annuity Plan Center. 

   You may change the amount to be transferred or cancel this service in writing
at any time. This service cannot be used to establish a new Portfolio, and will
not go into effect until the Free Look Period has expired.

Expenses

                                A CLOSER LOOK AT

                  The Costs of Investing in a Variable Annuity

Costs are an important consideration in choosing a variable annuity. That's
because you, as a contract owner, pay the costs of operating underlying mutual
funds, plus any transaction costs associated with the fund's buying and selling
of securities, as well as the costs associated with the annuity contract itself.
These combined costs can have a significant effect on the investment performance
of the annuity contract. Even seemingly small differences in mutual fund and
annuity contract expenses can, over time, have a dramatic effect on performance.

   The projected expenses for the Vanguard Variable Annuity Plan Contract are
substantially below the costs of other variable annuity contracts. For example,
on a $25,000 Contract the average expense ratio of other variable annuity
contracts was 2.15% as of December 31, 1998, compared to 0.69% for the Vanguard
Variable Annuity Plan Contract as of the date of this prospectus. (Source for
competitors' data: Morningstar Variable Annuity/Life Performance Report,

                         SUMMARY OF COSTS OF INVESTING

                 in the Vanguard Variable Annuity Plan Contract

 .  No sales load or sales charge
 .  No charge to make full or partial withdrawals
 .  No fee to exchange money among the Portfolios
 .  $25 Annual Contract Maintenance Fee on Contracts valued at less than $25,000
 .  Annual Mortality and Expense Risk Charge: 0.27%
 .  Annual Administrative Expense Charge: 0.10% 
 .  Fees and expenses paid by the Portfolios which ranged from 0.20% to 0.48% in
   the fiscal year ending September 30, 1998

   A fuller explanation of the expenses you would pay under the Contract
follows.

Mortality and Expense Risk Charge

The Company charges a fee as compensation for bearing certain mortality and
expense risks under the Contract. The annual charge is assessed daily based on
the combined net assets of the Separate Account and Separate Account IV of
Peoples Benefit Life Insurance Company in the Fund, according to the following
schedule:
     
   ---------------------------------------------------------------------
   Net Assets                                      Rate For All Assets 
   ---------------------------------------------------------------------
   Up to $2.5 billion                                     0.30% 
   Over $2.5 billion and up to $5 billion                 0.28 
   Over $5 billion                                        0.27
   ---------------------------------------------------------------------
   
   The charge is currently 0.27%.
   ---------------------------------------------------------------------

   The mortality and expense risk rates described above cannot be increased. If
the charge is more than sufficient to cover actual costs or assumed risks, any
excess will be added to the Company's surplus. If the charges collected under
the Contract are not enough to cover actual costs or assumed risks, then the
Company will bear the loss.

                                A CLOSER LOOK AT

                     The Mortality and Expense Risk Charge

The Company assumes mortality risk in two ways. First, where Contract Owners
elect an Annuity Payment Option under which the Company guarantees a number of
payments over a life or joint lives, the Company assumes the risk of making
monthly annuity payments regardless of how long all Annuitants may live. Second,
the Company assumes mortality risk in guaranteeing a minimum Death Benefit in
the event the Annuitant dies during the Accumulation Phase.
  
   The expense risk the Company assumes is that the charges for administrative
expenses, which are guaranteed not to increase beyond the rates shown for the
life of the Contract, may not be great enough to cover the actual costs of
issuing and administering the Contract.

Expenses (continued)

Administrative Expense Charge

The Company assesses each Contract an annual Administrative Expense Charge to
cover the cost of issuing and administering each Contract and of maintaining the
Separate Account. The Administrative Expense Charge is assessed daily at a rate
equal to 0.10% annually of the net asset value of the Separate Account.

Annual Contract Maintenance Fee

In certain situations, the Company charges an Annual Contract Maintenance Fee of
$25. The fee is to reimburse the Company for the costs it expects over the life
of the Contract for maintaining each Contract and the Separate Account. 

   The Company charges the fee if:

 .  Your Initial Purchase Payment is less than $25,000. In that case, your
   Initial Purchase Payment is reduced by a pro rated amount of the $25 fee to
   reflect the remaining portion of the calendar year of purchase.

 .  The Accumulated Value of your Contract is less than $25,000 on the last
   Business Day of any year. In that case, the fee will be deducted on the last
   Business Day of the year for the following year.

   The fee is deducted proportionately from each of the Portfolios you have
selected.

Fund Operating Expenses

The value of the assets in the Separate Account will reflect the fees and
expenses paid by Vanguard Variable Insurance Fund. A complete description of
these expenses is found in the "Fee Table" section of this prospectus and in the
"Management of the Fund" section of the Fund's Statement of Additional
Information.

Taxes

INTRODUCTION

The following discussion of annuity taxation is general in nature and is based
on the Company's understanding of the treatment of annuity contracts under
current federal income tax law, particularly Section 72 of the Internal Revenue
Code and various Treasury Regulations and Internal Revenue Service
interpretations dealing with Section 72. The discussion does not touch upon
state or local taxes. It is not tax advice. You should consult with a qualified
tax adviser about your particular situation to ensure that your purchase of a
Contract results in the tax treatment you desire. Additional discussion of tax
matters is included in the Statement of Additional Information.

TAXATION OF ANNUITIES IN GENERAL 

Tax Deferral

Special rules in the Internal Revenue Code for annuity taxation exist today. In
general, those rules provide that you are not currently taxed on increases in
value under a Contract until you take some form of withdrawal or distribution
from it. However, it is important to note that, under certain circumstances, you
might not get the advantage of tax deferral, meaning that the increase in value
would be subject to current federal income tax. (See ANNUITY CONTRACTS OWNED BY
NON-NATURAL PERSONS, page 27, and DIVERSIFICATION STANDARDS, page 28.)
<PAGE>
 
                                                                              25

                                A CLOSER LOOK AT

                                  Tax Deferral

Tax deferral means no current tax on earnings in your Contract. The amount you
would have paid in income taxes can be left in the Contract and earn money for
you.

   One tradeoff of tax deferral is that there are certain restrictions on your
ability to access your money, including penalty taxes for early withdrawals.
This is one reason why a variable annuity is intended as a long-term investment.

   Another tradeoff is that, when funds are withdrawn, they are taxed at
ordinary income rates instead of capital gains rates, which apply to certain
other sorts of investments.

Taxation of Full and Partial Withdrawals

If you make a full or partial withdrawal (including a Systematic Withdrawal)
from a Non-Qualified Contract during the Accumulation Phase, you as Contract
Owner will be taxed at ordinary income rates on earnings you withdraw at that
time. For purposes of this rule, withdrawals are taken first from earnings on
the Contract and then from the money you invested in the Contract. This
"investment in the contract" can generally be described as the cost of the
Contract, and it generally includes all Purchase Payments minus any amounts you
have already received under the Contract that represented the return of invested
money. Also for purposes of this rule, a pledge or assignment of a Contract is
treated as a partial withdrawal from a Contract. (If you are contemplating using
your Contract as collateral for a loan, you may be asked to pledge or assign
it.)

Taxation of Annuity Payments

When you take Annuity Payments in the Income Phase of a Non-Qualified Contract,
for tax purposes each payment is deemed to return to you a portion of your
investment in the Contract. Since with a Non-Qualified Contract you have already
paid taxes on those amounts (the Contract was funded with after-tax dollars),
you will not be taxed again on your investment - only on your earnings. 

   For fixed Annuity Payments from a Non-Qualified Contract, in general, the
Company calculates the taxable portion of each payment using a formula known as
the "exclusion ratio." This formula establishes the ratio that the investment in
the Contract bears to the total expected amount of Annuity Payments for the term
of the Contract. The Company then applies that ratio to each payment to
determine the non-taxable portion of the payment. The remaining portion of each
payment is taxable at ordinary income tax rates.

   For variable Annuity Payments from a Non-Qualified Contract, in general, the
Company calculates the taxable portion of each payment using a formula that
establishes a specific dollar amount of each payment that is not taxed. To find
the dollar amount, the Company divides the investment in the Contract by the
total number of expected periodic payments. The remaining portion of each
payment is taxable at ordinary income tax rates.

   Once your investment in the Contract has been returned, the balance of the
Annuity Payments represent earnings only and therefore are fully taxable.

Taxation of Withdrawals and Distributions From Qualified Contracts

Generally, the entire amount distributed from a Qualified Contract is taxable to
the Contract Owner. In the case of Qualified Contracts with after-tax
contributions, you may exclude the portion of each withdrawal or Annuity Payment
constituting a return of after-tax contributions. Once all of your after-tax
contributions have been returned to you on a non-taxable basis, subsequent
withdrawals or annuity
<PAGE>
 
26

Taxes (continued)

payments are fully taxable as ordinary income. Since the Company has no
knowledge of the amount of after-tax contributions you have made, you will need
to make this computation in the preparation of your federal income tax return.

Tax Withholding

Federal tax law requires that the Company withhold federal income taxes on all
distributions unless the recipient elects not to have any amounts withheld and
properly notifies the Company of that election. In certain situations, the
Company will withhold taxes on distributions to non-resident aliens at a flat
30% rate unless an exemption from withholding applies under an applicable tax
treaty.

Penalty Taxes on Certain Early Withdrawals

The Internal Revenue Code provides for a penalty tax in connection with certain
withdrawals or distributions that are includible in income. The penalty amount
is 10% of the amount includible in income that is received under an annuity.
However, there are exceptions to the penalty tax. For instance, it does not
apply to withdrawals: (i) made after the taxpayer reaches age 59 1/2; (ii) made
on or after the death of the Contract Owner or, where the Contract Owner is not
an individual, on or after the death of the primary Annuitant (who is defined as
the individual the events in whose life are of primary importance in affecting
the timing and payment under the Contracts); (iii) attributable to the
disability of the taxpayer which occurred after the purchase of the Contract (as
defined in the Internal Revenue Code); (iv) that are part of a series of
substantially equal periodic payments made at least annually for the life (or
life expectancy) of the taxpayer, or joint lives (or joint life expectancies) of
the taxpayer and his or her beneficiary; (v) from a Qualified Contract (note,
however, that other penalties may apply); (vi) under an immediate annuity
contract (as defined in the Internal Revenue Code); (vii) that can be traced to
an investment in the Contract prior to August 14, 1982; or (viii) under a
Contract that an employer purchases on termination of certain types of qualified
plans and that the employer holds until the employee separates from service.

   If the penalty tax does not apply to a withdrawal as a result of the
application of item (iv) above, and the series of payments is subsequently
modified (for some reason other than death or disability), the tax for the year
in which the modification occurs will be increased by an amount (as determined
under Treasury Regulations) equal to the penalty tax that would have been
imposed but for item (iv) above, plus interest for the deferral period. The
foregoing rule applies if the modification takes place (a) before the close of
the period that is five years from the date of the first payment and after the
taxpayer attains age 59 1/2, or (b) before the taxpayer reaches age 59 1/2.
Because the Company cannot predict whether the payments will be substantially
equal, the Company will report such withdrawals to the Internal Revenue Service
as early withdrawals with no known exception.

   For Qualified Contracts, other tax penalties may apply to certain
distributions as well as to certain contributions and other transactions.

   The penalty tax may not apply to distributions from Qualified Contracts
issued under Section 408(b) of the Internal Revenue Code that you use to pay
qualified higher education expenses or the acquisition costs (up to $10,000)
involved in the purchase of a principal residence by a first-time homebuyer.
Because the Company cannot verify that such an early withdrawal is for qualified
higher education expenses or a first home purchase, the Company will report such
withdrawals to the Internal Revenue Service as early withdrawals with no known
exception.

                                                                              27

ANNUITY CONTRACTS OWNED BY NON-NATURAL PERSONS

Where a non-natural person (for example, a corporation) holds a Contract, that
Contract is generally not treated as an annuity contract for federal income tax
purposes, and the income on that Contract (generally the increase in the net
Accumulated Value less the payments) is considered taxable income each year.
This rule does not apply where the non-natural person is only a nominal owner
such as a trust or other entity acting as an agent for a natural person. The
rule also does not apply where the estate of a decedent acquires a Contract,
where an employer purchases a Contract on behalf of an employee upon termination
of a qualified plan, or to an immediate annuity (as defined in the Internal
Revenue Code).

MULTIPLE-CONTRACTS RULE

All non-qualified annuity contracts issued by the same company (or affiliate) to
the same Contract Owner during any calendar year are to be aggregated and
treated as one contract for purposes of determining the amount includible in the
taxpayer's gross income. Thus, any amount received under any Contract prior to
the Contract's Annuity Date, such as a partial withdrawal, will be taxable (and
possibly subject to the 10% federal penalty tax) to the extent of the combined
income in all such contracts. The Treasury Department has specific authority to
issue regulations that prevent the avoidance of the multiple-contracts rules
through the serial purchase of annuity contracts or otherwise. In addition,
there may be other situations in which the Treasury Department may conclude that
it would be appropriate to aggregate two or more Contracts purchased by the same
Contract Owner. Accordingly, a Contract Owner should consult a tax adviser
before purchasing more than one Contract or other annuity contracts. (The
aggregation rules do not apply to immediate annuities (as defined in the
Internal Revenue Code).)

TRANSFERS OF ANNUITY CONTRACTS

Any transfer of a Non-Qualified Contract during the Accumulation Phase for less
than full and adequate consideration will generally trigger income tax (and
possibly the 10% federal penalty tax) on the gain in the Contract to the
Contract Owner at the time of such transfer. The transferee's investment in the
Contract will be increased by any amount included in the Contract Owner's
income. This provision, however, does not apply to transfers between spouses or
former spouses incident to a divorce that are governed by Internal Revenue Code
Section 1041(a).

ASSIGNMENTS OF ANNUITY CONTRACTS

A transfer of ownership in a Contract, a collateral assignment, or the
designation of an Annuitant or other beneficiary who is not also the Contract
Owner may result in tax consequences to the Contract Owner, Annuitant, or
beneficiary that this prospectus does not discuss. A Contract Owner considering
such a transfer or assignment of a Contract should contact a tax adviser about
the potential tax effects of such a transaction.

DIVERSIFICATION STANDARDS

To comply with certain regulations under Internal Revenue Code Section 817(h),
after a start-up period, each Subaccount of the Separate Account will be
required to diversify its investments in accordance with certain diversification
standards. A "look-through" rule applies that suggests that each Subaccount of
the Separate Account will be tested for compliance with the diversification
standards by looking through to the assets of the Portfolios in which each
Subaccount invests. 

   In connection with the issuance of temporary diversification regulations in
1986, the Treasury Department announced that such regulations did not provide
guidance on the extent to which Contract Owners may direct their investments to
particular subaccounts of a separate account. It is possible that regulations or
revenue rulings may be issued in this area at some time in the future. It is not
clear, at this time, what these regulations or rulings would provide. It is
possible that when the regulations or rulings are issued, the Contract may need
to be modified in order to remain in compliance. For these reasons, the Company
reserves the right to modify the Contract, as necessary, to maintain the
tax-deferred status of the Contract.

   We intend to comply with the diversification regulations to assure that the
Contract continues to be treated as an annuity contract for federal income tax
purposes.

QUALIFIED INDIVIDUAL RETIREMENT ANNUITIES

Generally, you may purchase Qualified Contracts only in connection with a
"rollover" of funds from another individual retirement annuity (IRA) or
qualified plan. Qualified Contracts must contain special provisions and are
subject to limitations on contributions and the timing of when distributions can
and must be made. Tax penalties may apply to contributions greater than
specified limits, loans, reassignments, distributions that do not meet specified
requirements, or in other circumstances. Anyone desiring to purchase a Qualified
Contract should consult a personal tax adviser.

Access To Your Money

The value of your Contract can be accessed during the Accumulation Phase: 

 .  By making a full or partial withdrawal.

 .  By electing an Annuity Payment Option.

 .  By your Beneficiary in the form of a Death Benefit.

Full and Partial Withdrawals

You may withdraw all or part of your money at any time during the Accumulation
Phase of your Contract without a Company charge, provided the Annuitant or Joint
Annuitant is still living. All partial withdrawals must be for at least $250.

   On the date the Company receives your request for a full withdrawal, the
amount payable is the Accumulated Value.

   On the date the Company receives your request for a partial withdrawal, the
Accumulated Value will be reduced by the amount of the partial withdrawal.

   Because you assume the investment risk under the Contract, the total amount
paid upon a full withdrawal of the Contract may be more or less than the total
Purchase Payments made (taking prior withdrawals into account).
<PAGE>
 
                                                                              29

   To make a withdrawal, send your written request to the Vanguard Variable
Annuity Plan Center. Your written request should include your Contract number,
Social Security number, the amount you wish to withdraw, how you want that
amount allocated among the various Portfolios, the signature of all Contract
Owners, and your federal tax withholding election.

Systematic Withdrawals

You may elect to have a specified dollar amount or a percentage of the balance
withdrawn from your Contract's Accumulated Value on a monthly, quarterly,
semiannual, or annual basis. The Company requires a Contract balance of at least
$10,000 and a Portfolio balance of at least $1,000 in order to establish the
systematic withdrawal program for your Contract. The minimum amount for each
Systematic Withdrawal is $250.

   You may elect this option by completing the Vanguard Variable Annuity Plan
Systematic Withdrawal Program Application Form. The Form must be signed by all
Contract Owners and must be signature-guaranteed if you are directing the
withdrawal payments to an address other than the Contract address.

   The Company must receive your Form at least 30 days before the date you want
systematic withdrawals to begin. The Company will process each Systematic
Withdrawal on the date and at the frequency you specified in your Systematic
Withdrawal Program Application Form.

   You may change the amount to be withdrawn and the percentage or the frequency
of distributions by telephone. Any other changes you make, including a change in
the destination of the check or your election to cancel this option, must be
made in writing, and should include signatures of all Contract Owners.

Minimum Balance Requirements

The minimum required balance in any Portfolio is $1,000. If an exchange or
withdrawal would reduce the balance in a Portfolio to less than $1,000, the
Company will transfer the remaining balance to the other Portfolios under the
Contract on a pro rata basis. If the entire value of the Contract falls below
$1,000, and if you have not made a Purchase Payment within three years, the
Company may notify you that the Accumulated Value of your Contract is below the
minimum balance requirement. In that case, you will be given 60 days to make an
Additional Purchase Payment before your Contract is liquidated. The Company
would then promptly pay proceeds to the Contract Owner. The proceeds would be
taxed as a withdrawal from the Contract. Full withdrawal will result in an
automatic termination of the Contract.

Payment of Full or Partial Withdrawal Proceeds

The Company will pay cash withdrawals within seven days after receipt of your
written request for withdrawal except in one of the following situations, in
which the Company may delay the payment beyond seven days: 

 .  The New York Stock Exchange is closed on a day that is not a weekend or a
   holiday, or trading on the New York Stock Exchange is otherwise restricted.

 .  An emergency exists as defined by the Securities and Exchange Commission (the
   "SEC"), or the SEC requires that trading be restricted.

 .  The SEC permits a delay for your protection as a Contract Owner.

 .  The payment is derived from premiums paid by check, in which case the Company
   may delay payment until the check has cleared your bank, which may take up to
   ten calendar days.

                            Taxation of Withdrawals

For important information on the tax consequences of withdrawals, see Taxation
of Full and Partial Withdrawals, page 25, and Penalty Taxes on Certain Early
Withdrawals, page 26.

Tax Withholding on Withdrawals

If you do not provide the Company with a written request not to have federal
income taxes withheld when you request a full or partial withdrawal, federal tax
law requires the Company to withhold federal income taxes from the taxable
portion of any withdrawal and send that amount to the federal government. In
that case, we will withhold at a rate of 10%.

Performance

Standardized Performance

From time to time, the Company may advertise the yield and total return
investment performance of a Portfolio for various periods, including
quarter-to-date, year-to-date, one-year, five-year, and since inception. The
Company will calculate advertised yields and total returns according to
standardized methods prescribed by the SEC, so that all charges and expenses
attributable to the Contract will be included. Including these fees has the
effect of decreasing the advertised performance of a Portfolio, so that a
Portfolio's investment performance will not be directly comparable to that of an
ordinary mutual fund.

Non-Standardized Performance

The Company may also advertise total return or other performance data in
non-standardized formats that do not reflect the Annual Contract Maintenance
Fee.

Not Indications of Future Performance

The performance measures discussed above are not intended to indicate or predict
future performance.

Statement of Additional Information

Please refer to the Statement of Additional Information for a description of the
method used to calculate a Portfolio's yield and total return and a list of the
indexes and other benchmarks used in evaluating a Portfolio's performance.

Death Benefit

In General

If the Annuitant dies during the Accumulation Phase, the Beneficiary will
receive the Death Benefit. The Death Benefit is either the then-current
Accumulated Value of the Contract or the sum of all Purchase Payments (minus any
partial withdrawals and any applicable Premium Taxes) - whichever is greater.
The Beneficiary may elect to receive these amounts as a lump sum or as Annuity
Payments. 

   Federal tax law requires that if a Contract Owner is a natural person and
dies before the Annuity Date, then the entire value of the Contract must be
distributed within five years of the date of death of the Contract Owner. If the
Contract Owner is not a natural person, the death of the primary Annuitant
triggers the same distribution requirement. Special rules may apply to a
surviving spouse.
<PAGE>
 
                                                                              31

Death of the Annuitant During the Accumulation Phase

If the Annuitant dies during the Accumulation Phase, the Beneficiary will be
entitled to the Death Benefit. When we receive Due Proof of Death of the
Annuitant, we will calculate the Death Benefit. The Beneficiary can choose to
receive the amount payable in a lump-sum cash benefit or under one of the
Annuity Payment Options. The Contract Owner can choose an Annuity Payment Option
for the Beneficiary before the Annuitant's death. However, if the Contract Owner
does not make such a choice and the Company has not already paid a cash benefit,
the Beneficiary may choose a payment option after the Annuitant's death.

   Paid as a lump sum, the Death Benefit is the greater of:

(1) The Accumulated Value on the date we receive Due Proof of Death; or

(2) The amount of all Purchase Payments made to date minus the amount of all
    partial withdrawals and Premium Taxes, if any.

   Paid under one of the Annuity Payment Options, the Death Benefit will be
based on the greater of:

(1) The Accumulated Value on the Annuity Date elected by the Beneficiary and
    approved by the Company; or

(2) The amount of all Purchase Payments minus the amount of all partial
    withdrawals and Premium Taxes, if any.

Death of the Annuitant During the Income Phase

The Death Benefit, if any, payable if the Annuitant dies during the Income Phase
depends on the Annuity Payment Option selected. Upon the Annuitant's death, the
Company will pay the Death Benefit, if any, to the Beneficiary under the Annuity
Payment Option in effect. For instance, if the Life Annuity With Period Certain
option has been elected, and if the Annuitant dies during the Income Phase, then
any unpaid payments certain will be paid to the Beneficiary.

                                   DEFINITION

                               Due Proof of Death

When the term "Due Proof of Death" is used in this prospectus we mean any of the
following:

 .  a certified death certificate

 .  a certified decree of a court of competent jurisdiction as to the finding of
   death

 .  a written statement by a medical doctor who attended the deceased

 .  any other proof satisfactory to the Company


                         A Word About Joint Annuitants

The Contract permits you as Contract Owner to name a Joint Annuitant. This can
have different effects depending on whether the Contract is in the Accumulation
Phase or the Income Phase. 

   During the Accumulation Phase, the Death Benefit is payable only after the
death of both the Annuitant and the Joint Annuitant.

   During the Income Phase, it will not matter that you have named a Joint
Annuitant unless you have chosen an Annuity Payment Option, such as the Joint
and Last Survivor Annuity option, that pays over the life of more than one
person. Therefore, if you have chosen an Annuity Payment Option that provides
income over the life of someone other than the person named as Joint Annuitant,
the Joint Annuitant's death during the Income Phase will have no effect on the
benefits due under the Contract.
<PAGE>

Death Benefit (continued)

Designation of a Beneficiary

The Contract Owner may select one or more Beneficiaries and name them on the
Enrollment Form. Thereafter, while the Annuitant or Joint Annuitant is living,
the Contract Owner may change the Beneficiary by written notice. The change will
take effect as of the date the Contract Owner signs the notice, but it will not
affect any payment made or any other action taken before the Company
acknowledges the notice. The Contract Owner may also make the designation of
Beneficiary irrevocable by sending written notice to the Company and obtaining
approval from the Company. Changes in the Beneficiary may then be made only with
the consent of the designated irrevocable Beneficiary. 

   If the Annuitant dies during the Accumulation Period, the following will
apply unless the Contract Owner has made other provisions:

 .  If there is more than one Beneficiary, each will share in the Death Benefit
   equally.

 .  If one or two or more Beneficiaries have already died, the Company will pay
   that share of the Death Benefit equally to the survivor(s).

 .  If no Beneficiary is living, the Company will pay the proceeds to the
   Contract Owner.

 .  If a Beneficiary dies at the same time as the Annuitant, the Company will pay
   the proceeds as though the Beneficiary had died first. If a Beneficiary dies
   within 15 days after the Annuitant's death and before the Company receives
   due proof of the Annuitant's death, the Company will pay proceeds as though
   the Beneficiary had died first.

   If a Beneficiary who is receiving Annuity Payments dies, the Company will pay
any remaining Payments Certain to that Beneficiary's named Beneficiary(ies) when
due. If no Beneficiary survives the Annuitant, the right to any amount payable
will pass to the Contract Owner. If the Contract Owner is not living at this
time, this right will pass to his or her estate.

Death of the Contract Owner

Death of the Contract Owner During the Accumulation Phase. With two exceptions,
federal tax law requires that when either the Contract Owner or the Joint Owner
(if any) dies during the Accumulation Phase, the Company must pay out the entire
value of the Contract within five years of the date of death. First exception:
If the entire value is to be distributed to the Owner's Designated Beneficiary,
he or she may elect to have it paid under an Annuity Payment Option over his or
her life or over a period certain no longer than his or her life expectancy as
long as the payments begin within one year of the Contract Owner's death. Second
exception: If the Owner's Designated Beneficiary is the spouse of the Contract
Owner (or Joint Owner), the spouse may elect to continue the Contract in his or
her name as Contract Owner indefinitely and to continue deferring tax on the
accrued and future income under the Contract. ("Owner's Designated Beneficiary"
means the natural person whom the Contract Owner names as a beneficiary and who
becomes the Contract Owner upon the Contract Owner's death.) If the Contract
Owner and the Annuitant are the same person, then upon that person's death the
Beneficiary is entitled to the Death Benefit. In this regard, see Death of the
Annuitant During the Accumulation Phase, page 31.

Death of the Contract Owner During the Income Phase. Federal tax law requires
that when either the Contract Owner or the Joint Owner (if any) dies during the
Income Phase, the Company must pay the remaining portions of the value of the
Contract at least as rapidly as under the method of distribution being used on
the date of death.

Non-Natural Person as Contract Owner. Where the Contract Owner is not a natural
person (for example, is a corporation), the death of the "primary Annuitant" is
treated as the death of the Contract Owner for purposes of federal tax law. (The
Internal Revenue Code defines a "primary Annuitant" as the individual who is of
primary importance in affecting the timing or the amount of payout under the
Contract.) In addition, where the Contract Owner is not a natural person, a
change in the identity of the "primary Annuitant" is also treated as the death
of the Contract Owner for purposes of federal tax law.

Payment of Lump-Sum Death Benefits

The Company will pay lump-sum Death Benefits within seven days after the
election to take a lump sum becomes effective except in one of the following
situations, in which the Company may delay the payment beyond seven days: 

 .  The New York Stock Exchange is closed on a day that is not a weekend or a
   holiday, or trading on the New York Stock Exchange is otherwise restricted.

 .  An emergency exists as defined by the SEC, or the SEC requires that trading
   be restricted.

 .  The SEC permits a delay for your protection as a Contract Owner.

 .  The payment is derived from premiums paid by check, in which case the Company
   may delay payment until the check has cleared your bank, which may take up to
   ten calendar days.

AUSA Life Insurance Company, Inc. (the "Company," "We," "Us," "Our")

AUSA Life Insurance Company, Inc. is a stock life insurance company incorporated
under the laws of the state of New York on October 3, 1947, with offices at 666
Fifth Avenue, New York, New York 10103. It is principally engaged in offering
life insurance and annuity contracts, and is licensed in the District of
Columbia and all states except Hawaii. 

   As of December 31, 1998, the Company had statutory-basis assets of
approximately $11.3 billion. It is a wholly owned indirect subsidiary of AEGON
USA, Inc., which conducts substantially all of its operations through subsidiary
companies engaged in the insurance business or in providing non-insurance
financial services. AEGON N.V. of The Netherlands indirectly owns all of the
stock of AEGON USA, Inc. AEGON N.V., a holding company, conducts its business
through subsidiary companies engaged primarily in the insurance business.

The First Providian Merger. On October 1, 1998, First Providian Life & Health
Insurance Company ("First Providian") merged with and into the Company. First
Providian was a stock life insurance company incorporated under the laws of the
state of New York on March 23, 1970. Upon the merger, First Providian's
existence ceased and the Company became the surviving company under the name
AUSA Life Insurance Company, Inc. As a result of the merger, the Separate
Account became a separate account of the Company. All of the Contracts issued by
First Providian before the merger were, at the time of the merger, assumed by
the Company. The merger did not affect any provisions of, or rights or
obligations under, those Contracts. In approving the merger on May 26, 1998, and
May 29, 1998, respectively, the boards of directors of the Company and First
Providian determined that the merger of two financially strong stock life
insurance companies would result in an overall enhanced capital position and
reduced expenses, which, together, would be in the long-term interests of the
Contract Owners. On May 26, 1998, 100% of the stockholders of the Company voted
to approve the merger, and on May 29, 1998, 100% of the stockholders of First
Providian voted to approve the merger. In addition, the New York Insurance
Department has approved the merger.

AUSA Life Insurance Company, Inc. Separate Account B

The Separate Account was established by First Providian, a former affiliate of
the Company, as a separate account under the laws of the state of New York on
November 2, 1987. On October 1, 1998, First Providian, together with the
Separate Account, was merged into the Company. The Separate Account survived the
merger intact. 

   The Separate Account is a unit investment trust registered with the SEC under
the Investment Company Act of 1940 (the "1940 Act"). Such registration does not
signify that the SEC supervises the management or the investment practices or
policies of the Separate Account.

   The Company owns the assets of the Separate Account, and the obligations
under the Contract are obligations of the Company. These assets are held
separately from the other assets of the Company and are not chargeable with
liabilities incurred in any other business operation of the Company (except to
the extent that assets in the Separate Account exceed the reserves and other
liabilities of the Separate Account). The Company will always keep assets in the
Separate Account with a value at least equal to the total Accumulated Value
under the Contracts. Income, gains, and losses incurred on the assets in the
Separate Account, whether or not realized, are credited to or charged against
the Separate Account without regard to other income, gains, or losses of the
Company. Therefore, the investment performance of the Separate Account is
entirely independent of the investment performance of the Company's general
account assets or any other separate account the Company maintains.

   The Separate Account has thirteen Subaccounts, each of which invests solely
in a corresponding Portfolio of the Fund. Additional Subaccounts may be
established at the Company's discretion. The Separate Account meets the
definition of a "separate account" under Rule O-1(e)(1) of the 1940 Act.

Contract

The Contracts described here are an individual annuity contract and a group
annuity contract. Until the October 1, 1998 merger of First Providian and AUSA
Life Insurance Company, Inc., the Vanguard Variable Annuity Plan Contract was
issued by First Providian as an individual annuity contract (the "Individual
Contract"). (For more information about the merger, see The First Providian
Merger at page 33.) Since the merger, AUSA Life Insurance Company, Inc. began
issuing the Vanguard Variable Annuity Plan Contract as a group annuity contract
(the "Group Contract"), participation in which is evidenced by a certificate
issued to the Contract Owner. Although the features of the Individual Contract
and those of the Group Contract are identical in most respects, certain
differences are noted in this prospectus.

Contract Owner ("You," "Your")

The Contract Owner is the person or persons designated as the Contract Owner in
the Enrollment Form to participate in the Contract. The term shall also include
any person named as Joint Owner. A Joint Owner shares ownership in all respects
with the Owner. The Owner has the right to assign ownership to a person or party
other than himself.

Payee

The Payee is the Contract Owner, Annuitant, Beneficiary, or any other person,
estate, or legal entity to whom benefits are to be paid.

                                                                              35

Free Look Periods

There are two different Free Look Periods depending on whether the Contract is a
replacement or not.

Free Look Period for Non-Replacement Contracts. If the Contract is not a
replacement of an existing annuity contract or life insurance or endowment
policy, the Contract provides for a Free Look Period of 20 days after the
Contract Owner receives the Contract plus 5 days for mailing. The Contract Owner
may cancel the Contract during the Free Look Period by returning it to the
Vanguard Variable Annuity Plan Center, P.O. Box 1103, Valley Forge, PA
19482-1103. Upon cancellation, the Contract is treated as void from the Contract
Date and the Contract Owner will receive the greater of the Purchase Payments
made under the Contract and any fees or other charges or the Accumulated Value
of the Contract as of the day the Contract is received by the Company.

Free Look Period for Replacement Contracts. If the Contract is a replacement of
an existing annuity contract or life insurance or endowment policy, a Free Look
Period exists for 60 days after the Contract Owner receives the Contract plus 5
days for mailing. Upon cancellation of a replacement Contract, the Contract is
treated as void from the Contract Date and the Contract Owner will receive the
greater of the Purchase Payments made under the Contract and any fees or other
charges or the Accumulated Value of the Contract as of the day the Company
receives the Contract.

   If the amount returned is based on Purchase Payments, the Contract Owner will
also receive the amount of any Mortality and Expense Risk Charges and
Administrative Expense Charges exacted to date.

   If the amount returned is based on the Accumulated Value, the Contract Owner
will also receive the amount of any prorated Annual Contract Maintenance Fee and
the amount of any Mortality and Expense Risk Charges and Administrative Expense
Charges exacted to date. (The prorated Annual Contract Maintenance Fee is
already included when calculating the amount returned based on Purchase
Payments.) Withdrawals are not permitted during the Free Look Period.

Reinstatements

The Company occasionally receives requests to reinstate a Contract whose funds
had been transferred to another company via an exchange under Internal Revenue
Code Section 1035 or a trustee-to-trustee transfer under the Internal Revenue
Code. In this situation, the Company will require the Contract Owner to replace
the same total amount of money in the applicable Subaccounts as was taken from
them to effect the transfer. The total dollar amount of funds reapplied to the
Separate Account will be used to purchase a number of Accumulation Units
available for each Subaccount based on the Accumulation Unit Values at the date
of Reinstatement (within two days of the date the funds were received by the
Company). It should be noted that the number of Accumulation Units available on
the Reinstatement date may be more or less than the number surrendered for the
transfer. Contract Owners should consult a qualified tax adviser concerning the
tax consequences of any Internal Revenue Code Section 1035 exchanges or
reinstatements.

Administrative Services

Administrative services are provided by The Vanguard Group, Inc., the Vanguard
Variable Annuity Plan Center, 100 Vanguard Boulevard, Malvern, PA 19355.
<PAGE>

Other Information (continued)

Distributor of the Contracts 

The Vanguard Group, Inc., through its wholly owned subsidiary, Vanguard
Marketing Corp., is the principal distributor of the Contract. For these
services, the Fund paid a fee of 0.02% of the Fund's average net assets for the
1998 fiscal year. This fee is guaranteed not to exceed 0.20% of the Fund's
average month-end net assets. A complete description of these services is found
in the "Management of the Fund" section of the Fund's Prospectus and in the
Fund's Statement of Additional Information. The principal business address for
the Vanguard Group, Inc. is 100 Vanguard Boulevard, Malvern, PA 19355.

Voting Rights

The Fund does not hold regular meetings of shareholders. The Trustees of the
Fund may call special meetings of shareholders as the 1940 Act or other
applicable law may require. To the extent required by law, the Company will vote
the Portfolio shares held in the Separate Account at shareholder meetings of the
Fund in accordance with instructions received from persons having voting
interests in the corresponding Portfolio. The Company will vote Fund shares as
to which no timely instructions are received and those shares held by the
Company as to which Contract Owners have no beneficial interest in proportion to
the voting instructions that are received with respect to all Contracts
participating in that Portfolio. Voting instructions to abstain on any item to
be voted upon will be applied on a pro rata basis to reduce the votes eligible
to be cast. 

   Prior to the Annuity Date, the Contract Owner holds a voting interest in each
Portfolio to which the Accumulated Value is allocated. The number of votes which
are available to a Contract Owner will be determined by dividing the Accumulated
Value attributable to a Portfolio by the net asset value per share of the
applicable Portfolio. After the Annuity Date, the person receiving Annuity
Payments under any variable Annuity Payment Option has the voting interest. The
number of votes after the Annuity Date will be determined by dividing the
reserve for such Contract allocated to the Portfolio by the net asset value per
share of the corresponding Portfolio. After the Annuity Date, the votes
attributable to a Contract decrease as the reserves allocated to the Portfolio
decrease. In determining the number of votes, fractional shares will be
recognized.

   The number of votes of the Portfolio that are available will be determined as
of the date established by that Portfolio for determining shareholders eligible
to vote at the meeting of the Fund. Voting instructions will be solicited by
written communication prior to such meeting in accordance with procedures
established by the Fund.

Additions, deletions, or substitutions of investments

The Company retains the right, subject to any applicable law, to make certain
changes. The Company reserves the right to eliminate the shares of any of the
Portfolios and to substitute shares of another Portfolio of the Fund or of
another registered open-end management investment company, if the shares of the
Portfolios are no longer available for investment or if, in the Company's
judgment, investment in any Portfolio would be inappropriate in view of the
purposes of the Separate Account. To the extent the 1940 Act requires,
substitutions of shares attributable to a Contract Owner's interest in a
Portfolio will not be made until SEC approval has been obtained and the Contract
Owner has been notified of the change.

   The Company may establish new Portfolios when marketing, tax, investment, or
other conditions so warrant. The Company will make any new Portfolios available
to existing Contract Owners on a basis the Company will determine. The Company
may also eliminate one or more Portfolios if marketing, tax, investment, or
other conditions so warrant.
<PAGE>
 
                                                                              37

   In the event of any such substitution or change, the Company may, by
appropriate endorsement, make whatever changes in the Contracts may be necessary
or appropriate to reflect such substitution or change. Furthermore, if deemed to
be in the best interests of persons having voting rights under the Contracts,
the Company may operate the Separate Account as a management company under the
1940 Act or any other form permitted by law, may deregister the Separate Account
under the 1940 Act in the event such registration is no longer required, or may
combine the Separate Account with one or more other separate accounts.

Year 2000 Readiness Disclosure

In May 1996, the Company adopted and presently has in place a Year 2000 Project
Plan (the "Year 2000 Plan") to review and analyze existing hardware and software
systems, as well as voice and data communications systems, to determine if they
are Year 2000 compliant. As of March 1, 1999, substantially all of the Company's
mission-critical systems are Year 2000 compliant. The Year 2000 Project Plan
remains on track as the Company continues with the validation of its
mission-critical and non-mission-critical systems, including revalidation
testing in 1999. In addition, the Company has undertaken aggressive initiatives
to test all systems that interface with any third parties and other business
partners. All of these steps are aimed at allowing current operations to remain
unaffected by the Year 2000 date change. 

   As of the date of this prospectus, the Company has identified and made
available what it believes are the appropriate resources of hardware, people,
and dollars, including the engagement of outside third parties, to ensure that
the Year 2000 Plan will be completed.

   The actions taken by management under the Year 2000 Plan are intended to
significantly reduce the Company's risk of a material business interruption
based on Year 2000 issues. It should be noted that the Year 2000 computer
problem, and its resolution, is complex and multifaceted, and any company's
success cannot be conclusively known until the Year 2000 is reached. In spite of
its efforts or results, the Company's ability to function unaffected to and
through the Year 2000 may be adversely affected by actions, or failures to act,
of third parties beyond our knowledge or control. 

   This statement is a Year 2000 Readiness Disclosure pursuant to Section 3(9)
of the Year 2000 Information and Readiness Disclosure Act, 15 U.S.C. Section 1
(1998).

Financial Statements

The audited statutory-basis financial statements of the Company and the audited
financial statements of the subaccounts of the Separate Account which are
available for investment by Vanguard Variable Annuity Plan Contract Owners (as
well as the Independent Auditors' Reports on them) are contained in the
Statement of Additional Information.

Auditors

Ernst & Young LLP serves as independent auditors for the Company and the
subaccounts of the Separate Account which are available for investment by
Vanguard Variable Annuity Plan Contract Owners and audits their financial
statements annually.

Legal Matters

The law firm of Jorden Burt Boros Cicchetti Berenson & Johnson LLP, of
Washington, D.C., has provided legal advice concerning the issue and sale of the
Contract under the applicable federal securities laws. On behalf of the Company,
Gregory E. Miller-Breetz, Esquire, has passed upon all matters of New York law
pertaining to the validity of the Contract and the Company's right to issue the
Contract.

                                  THE CONTRACT
                                        
  In order to supplement the description in the Prospectus, the following
provides additional information about the Contract which may be of interest to
Contract Owners.

Computation of Variable Annuity Income Payments
    
  Variable Annuity Income Payments are computed as follows. First, the
Accumulated Value (or the portion of the Accumulated Value used to provide
variable payments) is applied under the Annuity Table contained in the Contract
corresponding to the Annuity Option elected by the Contract Owner and based on
an assumed interest rate of 4%. This will produce a dollar amount which is the
first monthly payment.     

  The amount of each Annuity Payment after the first is determined by means of
Annuity Units. The number of Annuity Units is determined by dividing the first
Annuity Payment by the Annuity Unit value for the selected Subaccount on the
Annuity Date. The number of Annuity Units for the Subaccount then remains fixed,
unless an exchange of Annuity Units (as set forth below) is made. After the
first Annuity Payment, the dollar amount of each subsequent Annuity Payment is
equal to the number of Annuity Units multiplied by the Annuity Unit value for
the Subaccount on the due date of the Annuity Payment.

  The Annuity Unit value for each Subaccount was initially established at $10.00
on the day money was first deposited in that Subaccount. The Annuity Unit value
for any subsequent Business Day is equal to (a) times (b) times (c), where:

  (a) the Annuity Unit value for the immediately preceding Business Day;

  (b) the Net Investment Factor for the day;
    
  (c) the investment result adjustment factor (0.99989255 per day), which
      recognizes an assumed interest rate of 4% per year used in determining the
      Annuity Payment amounts.     

  The Net Investment Factor is a factor applied to a Subaccount that reflects
daily changes in the value of the Subaccount due to:

  (a) any increase or decrease in the value of the Subaccount due to investment
      results;

  (b) a daily charge for the mortality and expense risks assumed by the Company
      corresponding to an annual rate according to the following schedule:

     Rate For
     Net Assets*                                 All Assets
     -----------                                 ----------

     Up to $2.5 Billion............................ 0.30%
     Over $2.5 Billion and Up To $5 Billion........ 0.28%
     Over $5 Billion............................... 0.27%

- ---------

*  Based on combined net assets of the Separate Account and Separate Account IV
   Peoples Benefit Life Insurance Company.
    
   (c) a daily charge for the cost of administering the Contract corresponding
       to an annual charge of 0.10%.     

   (d) an annual charge of $25 for maintenance of Contracts valued at less than
       $25,000 at time of initial purchase and on the last business day of each
       year.

   The Annuity Tables contained in the Contract are based on the 1983 Table "A"
Mortality Table projected for mortality improvement to the year 2000 using
Projection Scale G and an interest rate of 4% a year.


                                      B-2

Exchanges
    
  After the Annuity Date, if a Variable Annuity Option has been chosen, the
Contract Owner may, by written request, exchange the current value of the
existing Subaccount to Annuity Units of any other Subaccount then available. The
request for the exchange must be received, however, at least 10 Business Days
prior to the first payment date on which the exchange is to take effect. This
exchange shall result in the same dollar amount of Annuity Payment on the date
of exchange. The Contract Owner is limited to two substantive exchanges (at
least 30 days apart) from a Portfolio (except the Money Market Portfolio) in any
Contract Year, and the value of the Annuity Units exchanged must provide a
monthly Annuity Payment of at least $100 at the time of the exchange.
"Substantive" means  a dollar amount that The Vanguard Group, Inc. determines,
in its sole discretion, could adversely affect management of the Fund.     

  Exchanges will be made using the Annuity Unit value for the Subaccounts on the
date the request for exchange is received by the Company. On the exchange date,
the Company will establish a value for the current Subaccount by multiplying the
Annuity Unit value by the number of Annuity Units in the existing Subaccount,
and compute the number of Annuity Units for the new Subaccount by dividing the
Annuity Unit value of the new Subaccount into the value previously calculated
for the existing Subaccount.

Joint Annuitant

  The Contract Owner may, in the Contract enrollment form or by written request
at least 30 days prior to the Annuity Date, name a Joint Annuitant. Such Joint
Annuitant must meet the Company's underwriting requirements. If approved by the
Company, the Joint Annuitant shall be named on the Contract Schedule or added by
endorsement. An Annuitant or Joint Annuitant may not be replaced.

  The Annuity Date shall be determined based on the date of birth of the
Annuitant. If the Annuitant or Joint Annuitant dies prior to the Annuity Date,
the survivor shall be the sole Annuitant. Another Joint Annuitant may not be
designated. Payment to a Beneficiary shall not be made until the death of the
surviving Annuitant.

                                GENERAL MATTERS

Non-Participating

  The Contracts are non-participating. No dividends are payable and the
Contracts will not share in the profits or surplus earnings of the Company.

Misstatement of Age or Sex

  The Company may require proof of age and sex before making Annuity Payments.
If the Annuitant's stated age, sex or both in the Contract are incorrect, the
Company will change the Annuity Benefits payable to those which the Purchase
Payments would have purchased for the correct age and sex. In the case of
correction of the stated age or sex after payments have commenced, the Company
will: (1) in the case of underpayment, pay the full amount due with the next
payment; or (2) in the case of overpayment, deduct the amount due from one or
more future payments.

Assignment

  Any Nonqualified Contract may be assigned by the Contract Owner prior to the
Annuity Date and during the Annuitant's lifetime. The Company is not responsible
for the validity of any assignment. No assignment will be recognized until the
Company receives written notice thereof. The interest of any Beneficiary which
the assignor has the right to change shall be subordinate to the interest of an
assignee. Any amount paid to the assignee shall be paid in one sum,
notwithstanding any settlement agreement in effect at the time assignment was
executed. The Company shall not be liable as to any payment or other settlement
made by the Company before receipt of written notice.

                                      B-3
<PAGE>
 
Annuity Data

  The Company will not be liable for obligations which depend on receiving
information from a Payee until such information is received in a form
satisfactory to the Company.

Annual Report

  Once each Contract Year, the Company will send the Contract Owner an annual
report of the current Accumulated Value allocated to each Subaccount; and any
Purchase Payments, charges, exchanges or withdrawals during the year. This
report will also give the Contract Owner any other information required by law
or regulation. The Contract Owner may ask for a report like this at any time.

Incontestability

  This Contract is incontestable from the Contract Date, subject to the
"Misstatement of Age or Sex" provision.

Ownership

  The Owner of the Contract on the Contract Date is the Annuitant, unless
otherwise specified in the enrollment form. The Owner may specify a new Owner by
written notice at any time thereafter. The term Owner also includes any person
named as a Joint Owner. A Joint Owner shares ownership in all respects with the
Owner. During the Annuitant's lifetime all rights and privileges under this
Contract may be exercised solely by the Owner. Upon the death of the Owner(s),
Ownership is retained by the surviving Joint Owner or passes to the Owner's
Designated Beneficiary, if one has been designated by the Owner. If no Owner's
Designated Beneficiary is designated or if no Owner's Designated Beneficiary is
living, the Owner's Designated Beneficiary is the Owner's estate.  From time to
time the Company may require proof that the Owner is still living.

                          DISTRIBUTION OF THE CONTRACT
    
  The Vanguard Group, Inc. through its wholly-owned subsidiary, Vanguard
Marketing Corporation, is the principal distributor of the Contracts. For these
services, the Fund paid a fee of 0.02% of the Fund's average net assets for its
1998 fiscal year. This fee is guaranteed not to exceed 0.20% of the Fund's
average month-end net assets. A complete description of these services is found
in the section of the Fund's Prospectus entitled "The Portfolios and Vanguard"
and in the Fund's Statement of Additional Information.  The principal business
address for The Vanguard Group, Inc. is The Vanguard Variable Annuity Plan
Center, 100 Vanguard Boulevard, Malvern, PA 19355.     

                            PERFORMANCE INFORMATION

  Performance information for the Subaccounts, including the yield and effective
yield of the Money Market Subaccount, the yield of the remaining Subaccounts,
and the total return of all Subaccounts, may appear in reports or promotional
literature to current or prospective Contract Owners. The yield and total return
performance information presented below reflects the operations of the
Subaccounts in connection with the individual variable annuity contracts offered
through First Providian Life & Health Insurance Company Separate Account B,
which was acquired intact by AUSA Life Insurance Company, Inc., on October 1,
1998. As of October 1, 1998, new individual variable annuity contracts no longer
are offered for sale.
    
Subaccount Inception Dates

  Where applicable, the following Subaccount inception dates are used in the
calculation of performance figures: December 1, 1992 for the Money Market
Subaccount; December 16, 1992 for the Equity Index Subaccount, the Balanced
Subaccount, and the High-Grade Bond Subaccount; June 7, 1993 for the Equity
Income Subaccount and the Growth Subaccount; June 3, 1994 for the International
Subaccount; and June 3, 1996 for the High Yield Bond Subaccount and the Small
Company Growth Subaccount.  As of December 31, 1998, the Short-Term Corporate
Subaccount, the Diversified Value Subaccount, the Mid-Cap Index Subaccount, and
the REIT Index Subaccount had not commenced operations.     

                                      B-4
<PAGE>
 
Money Market Subaccount Yields
    
  Current yield for the Money Market Subaccount will be based on the change in
the value of a hypothetical investment (exclusive of capital changes) over a
particular 7-day period, less a pro-rata share of Subaccount expenses accrued
over that 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.      

  Calculation of "effective yield" begins with the same "base period return"
used in the calculation of yield, which is then annualized to reflect weekly
compounding pursuant to the following formula:
    
              Effective Yield = [(Base Period Return +1)/365/7/] -1       
    
  The yield of the Money Market Subaccount for the 7-day period ended December
31, 1998, was 4.71%.     

30-Day Yield for Non-Money Market Subaccounts

  Quotations of yield for the remaining Subaccounts will be based on all
investment income per Unit earned during a particular 30-day period, less
expenses accrued during the period ("net investment income"), and will be
computed by dividing net investment income by the value of a Unit on the last
day of the period, according to the following formula:
    
                           YIELD = 2[(a - b + 1)/6/ -1]        
                                      -----          
                                      c x d       

Where:

[a]  equals the net investment income earned during the period by the Series
     attributable to shares owned by a Subaccount

[b]  equals the expenses accrued for the period (net of reimbursements)

[c]  equals the average daily number of Units outstanding during the period

[d]  equals the maximum offering price per Accumulation Unit on the last day of
     the period

  Yield on the Subaccount is earned from the increase in net asset value of
shares of the Series in which the Subaccount invests and from dividends declared
and paid by the Series, which are automatically reinvested in shares of the
Series.
    
  The yield of each Subaccount for the 30-day period ended December 31, 1998, is
set forth below. Yields are calculated daily for each Subaccount. Premiums and
discounts on asset-backed securities are not amortized.

  High-Grade Bond Subaccount........................... 5.15%
  High Yield Bond Subaccount........................... 8.53%
  Short-Term Corporate Subaccount...................... ---
  Balanced Subaccount.................................. 3.08%
  Diversified Value Subaccount......................... ---

"Standardized Average Annual Total Return," calculated as prescribed by the
rules of the SEC, for each Subaccount. The Standardized Average Annual Total
Return is the effective annual compounded rate of return that would have
produced the cash redemption value over the stated period had the performance
remained constant throughout. The calculation assumes a single $1,000 payment
made at the beginning of the period and full redemption at the end of the
period. It reflects the deduction of all applicable sales loads or sales
charges, the Annual Contract Maintenance Fee and all other Portfolio, Separate
Account and Contract level charges except Premium Taxes, if any. In calculating
performance information, the Annual Contract Maintenance Fee is reflected as a
percentage equal to the total amount of fees collected during a year divided by
the total average net assets of the Portfolios during the same year. The fee is
assumed to remain the same in each year of the applicable period. The fee is
prorated to reflect only the remaining portion of the calendar year of purchase.
Thereafter, the fee is deducted on the last business day of the year for the
following year, on a pro rata basis, from each of the Portfolios you have
chosen.     
    
  Quotations of average annual total return for any Subaccount will be expressed
in terms of the average annual compounded rate of return of a hypothetical
investment in a Contract over a period of one, three, five and 10 years (or, if
less, up to the life of the Subaccount) and year-to-date, six months to date,
month-to-date, and quarter-to-date, calculated pursuant to the formula:     
    
                                P(1 + T)/n/ = ERV       
Where:

(1)  [P] equals a hypothetical Initial Purchase Payment of $1,000

(2)  [T] equals an average annual total return

(3)  [n] equals the number of years

(4)  [ERV] equals the ending redeemable value of a hypothetical $1,000 Purchase
     Payment made at the beginning of
  the period (or fractional portion thereof)
    
  The following tables show the average annual total return for the Subaccounts
for the period beginning at the inception of each Subaccount and ending on
December 31, 1998.

  All total return figures reflect the deduction of the administrative charge,
and the mortality and expense risk charge. The SEC requires that an assumption
be made that the Contract Owner surrenders the entire Contract at the end of the
1-, 5- and 10-year periods (or, if less, up to the life of the Subaccount) for
which performance is required to be calculated.

  Performance information for a Subaccount may be compared, in reports and
promotional literature, to: (i) the Standard & Poor's 500 Stock Index ("S&P
500"), Dow Jones Industrial Average ("DJIA"), Donoghue Money Market
Institutional Averages, or other indices that measure performance of a pertinent
group of securities so that investors may compare a Subaccount's results with
those of a group of securities widely regarded by investors as representative of
the securities markets in general; (ii) other groups of variable annuity
separate accounts or other investment products tracked by Lipper Analytical
Services, a widely-used independent research firm which ranks mutual funds and
other investment companies by overall performance, investment objectives, and
assets, or tracked by other services, companies, publications, or persons who
rank such investment companies on overall performance or other criteria; and
(iii) the Consumer Price Index (measure for inflation) to assess the real rate
of return from an investment in the Contract. Unmanaged indices may assume the
reinvestment of dividends but generally do not reflect deductions for
administrative and management costs and expenses.

  Performance information for any Subaccount reflects only the performance of a
hypothetical Contract under which Accumulation Value is allocated to a
Subaccount during a particular time period on which the calculations are based.
Performance information should be considered in light of the investment
objectives and policies, characteristics and quality of the portfolio of the
Fund in which the Subaccount invests, and the market conditions during the given
time period, and should not be considered as a representation of what may be
achieved in the future.

  Reports and marketing materials may, from time to time, include information
concerning the rating of AUSA Life Insurance Company, Inc. as determined by A.M.
Best, Moody's, Standard & Poor's or other recognized rating services. Reports
and promotional literature may also contain other information including (i) the
ranking of any Subaccount derived from rankings of variable annuity separate
accounts or other investment products tracked by Lipper Analytical Services or
by other rating services, companies, publications, or other persons who rank
separate accounts or other investment products on overall performance or other
criteria, and (ii) the effect of tax deferred compounding on a Subaccount's
investment returns, or returns in general, which may be illustrated by graphs,
charts, or otherwise, and which may include a comparison, at various points in
time, of the return from an investment in a Contract (or returns in general) on
a tax-deferred basis (assuming one or more tax rates) with the return on a
taxable basis.

                        ADDITIONAL PERFORMANCE MEASURES

Non-Standardized Cumulative Total Return and Non-Standardized Average Annual
Total Return

  The Company may show Non-Standardized Cumulative Total Return (i.e., the
percentage change in the value of an Accumulation Unit) for one or more
Subaccounts with respect to one or more periods. The Company may also show Non-
Standardized Average Annual Total Return (i.e., the average annual change in
Accumulation Unit Value) with respect to one or more periods. For one year and
periods less than one year, the Non- Standardized Cumulative Total Return and
the Non-Standardized Average Annual Total Return are effective annual rates of
return and are equal. For periods greater than one year, the Non-Standardized
Average Annual Total Return is the effective annual compounded rate of return
for the periods stated. Because the value of an Accumulation Unit reflects the
Separate Account and Portfolio expenses (see Fee Table in the Prospectus), the
Non-Standardized Cumulative Total Return and Non-Standardized Average Annual
Total Return also reflect these expenses. However, these percentages do not
reflect the Annual Contract Maintenance Fee or Premium Taxes (if any), which, if
included, would reduce the percentages reported by the Company.

                         SAFEKEEPING OF ACCOUNT ASSETS

  Title to assets of the Separate Account is held by the Company. The assets are
kept physically segregated and held separate and apart from the Company's
general account assets. Records are maintained of all purchases and redemptions
of eligible Portfolio shares held by each of the Subaccounts.
    
               CONFLICTS OF INTEREST WITH OTHER SEPARATE ACCOUNTS     
    
  The Portfolios may be made available to registered separate accounts offering
variable annuity and variable life products of the Company or other insurance
companies. Although the Company believes it is unlikely, a material conflict
could arise between the interests of the Separate Account and one or more of the
other participating separate accounts. In the event a material conflict does
exist, the affected insurance companies agree to take any necessary steps,
including removing their separate accounts from the Fund if required by law, to
resolve the matter.     

                                  THE COMPANY
    
  On October 1, 1998, First Providian Life & Health Insurance Company ("First
Providian") merged with and into the Company. First Providian was a stock life
insurance company incorporated under the laws of the State of New York on March
23, 1970. Upon the merger, First Providian's existence ceased and the Company
became the surviving company under the name AUSA Life Insurance Company, Inc. As
a result of the merger, the Separate Account became a separate account of the
Company. All of the Contracts issued by First Providian before the merger were,
at the time of the merger, assumed by the Company. The merger did not affect any
provisions of, or rights or obligations under, those Contracts. In approving the

                                     TAXES        
    
  The Company is taxed as a life insurance company under Part I of Subchapter L
of the Internal Revenue Code. Since the Separate Account is not a separate
entity from the Company and its operations form a part of the Company, the
Separate Account will not be taxed separately as a "regulated investment
company" under Subchapter M of the Internal Revenue Code. Investment income and
realized capital gains on the assets of the Separate Account are reinvested and
taken into account in determining the Accumulated Value. Under existing federal
income tax law, the Separate Account's investment income, including realized net
capital gains, is not taxed to the Company. The Company reserves the right to
make a deduction for taxes should they be imposed with respect to such items in
the future.     
    
  Under present laws, the Company will not incur New York state or local taxes.
If there is a change in state or local tax laws, the Company may make charges
for such taxes. The Company does not expect to incur any federal income tax
liability attributable to investment income or capital gains retained as part of
the reserves under the Contracts. Based upon these expectations, no charge is
currently being made to the Separate Account for corporate federal income taxes
that may be attributable to the Separate Account.     
    
   The Company will periodically review the question of a charge to the Separate
Account for corporate federal income taxes related to the Separate Account. Such
a charge may be made in future years for any federal income taxes the Company
incurs. This might become necessary if the Company ultimately determines that
its tax treatment is not what it currently believes it to be, if there are
changes in the federal income tax treatment of annuities at the corporate level,
or if there is a change in the Company's tax status. If the Company should incur
federal income taxes attributable to investment income or capital gains retained
as part of the reserves under the Contracts, the Accumulated Value of the
Contract would be correspondingly adjusted by any provision or charge for such
taxes.     

                        STATE REGULATION OF THE COMPANY

  The Company is subject to the laws of New York governing insurance companies
and to regulation by the New York Department of Insurance. An annual statement
in a prescribed form is filed with the Department of Insurance each year
covering the operation of the Company for the preceding year and its financial
condition as of the end of such year. Regulation by the Department of Insurance
includes periodic examination to determine the Company's contract liabilities
and reserves so that the Department may determine if the items are correct. The
Company's books and accounts are subject to review by the Department of
Insurance at all times. In addition, the Company is subject to regulation under
the insurance laws of other jurisdictions in which it may operate.

                              RECORDS AND REPORTS

  All records and accounts relating to the Separate Account will be maintained
by the Company or by its administrator, The Vanguard Group, Inc. As presently
required by the Investment Company Act of 1940 and regulations promulgated
thereunder, the Company will mail to all Contract Owners at their last known
address of record, at least semiannually, reports containing such information as
may be required under that Act or by any other applicable law or regulation.

                               LEGAL PROCEEDINGS

  There are no legal proceedings to which the Separate Account is a party or to
which the assets of the Separate Account are subject. The Company is not
involved in any litigation that is of material importance in relation to its
total assets or that relates to the Separate Account.

                        Report of Independent Auditors



The Board of Directors and Contract Owners 
of the Vanguard Variable Annuity Plan, 
AUSA Life Insurance Company, Inc.


We have audited the accompanying balance sheet of the subaccounts of AUSA Life
Insurance Company, Inc. Separate Account B (formerly the First Providian Life
and Health Insurance Company Separate Account B), which are available for
investment by the Vanguard Variable Annuity Plan contract owners, as of December
31, 1998, and the related statements of operations for the year then ended and
changes in contract owners' equity for each of the two years in the period then
ended. These financial statements are the responsibility of the Variable
Account's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of mutual fund shares owned as of December 31, 1998, by
correspondence with the mutual funds' transfer agent. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the subaccounts of the AUSA
Life Insurance Company, Inc. Separate Account B, which are available for
investment by the Vanguard Variable Annuity Plan contract owners, at December
31, 1998, and the results of their operations for the year then ended and
changes in their contract owners' equity for each of the two years in the period
then ended in conformity with generally accepted accounting principles.

1. Organization and Summary of Significant Accounting Policies

Organization

AUSA Life Insurance Company, Inc. Separate Account B (the "Mutual Fund
Account"), formerly First Providian Life and Health Insurance Company Separate
Account B, is a segregated investment account of AUSA Life Insurance Company,
Inc. ("AUSA"), an indirect, wholly-owned subsidiary of AEGON N.V., a holding
company organized under the laws of The Netherlands.

The Mutual Fund Account is registered with the Securities and Exchange
Commission as a Unit Investment Trust pursuant to provisions of the Investment
Company Act of 1940. The Mutual Fund Account consists of nine investment
subaccounts which invest exclusively in shares of a corresponding portfolio of
the Vanguard Variable Insurance Fund (the "Series Fund"), an open-end
diversified investment company offered by The Vanguard Group, Inc. ("Vanguard").
Activity in these nine investment subaccounts is available to contract owners of
the Vanguard Variable Annuity Plan.

Prior to October 1, 1998, the Mutual Fund Account was a segregated investment
account of First Providian Life and Health Insurance Company ("FPLH"). On
October 1, 1998, FPLH merged with and into AUSA. Upon the merger, FPLH's
existence ceased and AUSA became the surviving company. As a result of the
merger, the Mutual Fund Account became a segregated investment account of AUSA.
All of the contracts issued by FPLH before the merger were, at the time of the
merger, assumed by AUSA.

Prior to June 10, 1997, FPLH was an indirect, wholly-owned subsidiary of
Providian Corporation ("Providian"). On June 10, 1997, Providian's insurance
operations, including the operations of FPLH, were merged with an indirect,
wholly-owned subsidiary of AEGON N.V. Providian was the surviving corporation in
the merger. Effective October 15, 1997, Providian's name was changed to
Commonwealth General Corporation ("CGC"). Effective December 31, 1997, ownership
of CGC was transferred to AEGON USA, Inc., an indirect, wholly-owned subsidiary
of AEGON N.V.

Investments

Net purchase payments received by the Mutual Fund Account for the Vanguard
Variable Annuity Plan are invested in the portfolios of the Series Fund, as
selected by the contract owner. Investments are stated at the closing net asset
values per share on December 31, 1998.

1. Organization and Summary of Significant Accounting Policies (continued)

Prior to August 11, 1998, realized capital gains and losses from the sale of
shares in the Series funds were determined on the basis of average cost.
Subsequent to this date, such gains or losses are determined on the first-in,
first-out basis. This change was implemented by establishing the average cost of
the portfolio as of August 11, 1998 as the opening cost for purposes of the
first-in, first-out basis. This change has no effect on "net realized and
unrealized capital gain (loss) from investments" and "increase (decrease) from
operations" as reported in the Statement of Operations. Investment transactions
are accounted for on the trade date (date the order to buy or sell is executed)
and dividend income is recorded on the ex-dividend date. Unrealized gains or
losses from the investments in the Series Funds are credited or charged to
contract owners' equity.

Dividend Income

Dividends received from the Series Funds investments are reinvested to purchase
additional mutual fund shares.

4. Administrative, Mortality and Expense Risk Charge

An annual charge is deducted from the unit values of the subaccounts of the
Mutual Fund Account for AUSA's assumption of certain mortality and expense risks
incurred in connection with the contract. It is assessed daily based on the
Series Funds' combined net assets attributable to the Mutual Fund Account and
Separate Account IV of Peoples Benefit Life Insurance Company ("PBL"), an
affiliate of AUSA. The annual rate was .375% on the first $1.5 billion of
combined net assets in the Series Funds and was reduced to .30% of combined net
assets in the Series Funds in excess of $1.5 billion. Effective December 1,
1997, the annual rate changed to .30% on the first $2.5 billion of combined net
assets in the Series Funds, is reduced to .28% of combined net assets in the
Series Funds over $2.5 billion and up to $5 billion, and is further reduced to
 .27% of combined net assets in the Series Funds in excess of $5 billion.

4. Administrative, Mortality and Expense Risk Charge (continued)

An administrative charge of .10% annually is deducted from the unit value of the
subaccounts of the Mutual Fund Account. This charge is assessed daily by AUSA
based on the Series Funds' net assets attributable to the Mutual Fund Account
and Separate Account IV of PBL. Additionally, an annual maintenance fee of $25
per contract is charged for contracts valued at less than $25,000 at the time of
initial purchase and on the last business day of each year. The maintenance fee
is deducted proportionately from the contract's accumulated value. These
deductions represent reimbursement to Vanguard for the costs expected to be
incurred for issuing and maintaining each contract and the Mutual Fund Account.


5. Taxes

Operations of the Mutual Fund Account form a part of AUSA which is taxed as a
life insurance company under Subchapter L of the Internal Revenue Code of 1986,
as amended (the "Code"). The operations of the Mutual Fund Account are accounted
for separately from other operations of AUSA for purposes of federal income
taxation. The Mutual Fund Account is not separately taxable as a regulated
investment company under Subchapter M of the Code and is not otherwise taxable
as an entity separate from AUSA. Under existing federal income tax laws, the
income of the Mutual Fund Account, to the extent applied to increase reserves
under the variable annuity contracts, is not taxable to AUSA.


6. Year 2000 (Unaudited)

The term Year 2000 Issue generally refers to the improper processing of dates
and incorrect date calculations that might occur in computer software and
hardware and embedded systems as the Year 2000 is approached. The use of
computer programs that rely on two-digit date fields to perform computations and
decision-making functions may cause systems to malfunction when processing
information involving dates after 1999. For example, any computer software that
has date-sensitive coding might recognize a code of 00 as the year 1900 rather
than the year 2000.

AUSA has developed a Year 2000 Project Plan (the Plan) to address the Year 2000
issue as it affects AUSA's internal IT and non-IT systems, and to assess Year
2000 issues relating to third parties with whom AUSA has critical relationships.

6. Year 2000 (Unaudited) (continued)

The Plan for addressing internal systems generally includes an assessment of
internal IT and non-IT systems and equipment affected by the Year 2000 issue;
definition of strategies to address affected systems and equipment; remediation
of identified systems and equipment; internal testing and certification that
each internal system is Year 2000 compliant; and a review of existing and
revised business resumption and contingency plans to address potential Year 2000
issues. AUSA has remediated and tested substantially all of its mission-critical
internal IT systems as of December 31, 1998. AUSA continues to remediate and
test certain non-critical internal IT systems, internal non-IT systems and will
continue with a revalidation testing program throughout 1999.

AUSA's Year 2000 issues are more complex because a number of its systems
interface with other systems not under AUSA's control. AUSA's most significant
interfaces and uses of third-party vendor systems are in the bank, financial
services and trust areas. AUSA utilizes various banks to handle numerous types
of financial and sales transactions. Several of these banks also provide trustee
and custodial services for AUSA's investment holdings and transactions. These
services are critical to a financial services company such as AUSA as its
business centers around cash receipts and disbursements to policyholders and the
investment of policyholder funds. AUSA has received written confirmation from
its vendor banks regarding their status on Year 2000. The banks indicate their
dedication to resolving any Year 2000 issues related to their systems and
services prior to December 31, 1999. AUSA anticipates that a considerable effort
will be necessary to ensure that its corrected or new systems can properly
interface with those business partners with whom it transmits and receives data
and other information (external systems). AUSA has undertaken specific testing
regimes with these third-party business partners and expects to continue working
with its business partners on any interfacing of systems. However, the timing of
external system compliance cannot currently be predicted with accuracy because
the implementation of Year 2000 readiness will vary from one company to another.

AUSA does have some exposure to date sensitive embedded technology such as
micro-controllers, but AUSA views this exposure as minimal. Unlike other
industries that may be equipment intensive, like manufacturing, AUSA is a life
insurance, and financial services organization providing insurance, annuities
and pension products to its customers. As such, the primary equipment and
electronic devices in use are computers and telephone related equipment. This
type of hardware can have date sensitive embedded technology which could have
Year 2000 problems. Because of this exposure, AUSA has reviewed its computer
hardware and telephone systems, with assistance from the applicable vendors, and
has upgraded, or replaced, or is in the process of replacing any equipment that
will not properly process date sensitive data in the Year 2000 or beyond. This
undertaking has been substantially completed for all operations.

6. Year 2000 (Unaudited) (continued)

For AUSA, a reasonably likely worst case scenario might include one or more of
AUSA's significant policyholder systems being non-compliant. Such an event could
result in a material disruption of AUSA's operations. Specifically, a number of
AUSA's operations could experience an interruption in the ability to collect and
process premiums or deposits, process claim payments, accurately maintain
policyholder information, accurately maintain accounting records, and or perform
adequate customer service. Should the worst case scenario occur, it could,
dependent upon its duration, have a material impact on AUSA's business and
financial condition. Simple failures can be repaired and returned to production
within a matter of hours with no material impact. Unanticipated failures with a
longer service disruption period could have a more serious impact. For this
reason, AUSA is placing significant emphasis on risk management and Year 2000
business resumption contingency planning in 1999 by modifying its existing
business resumption and disaster recovery plans to address potential Year 2000
issues.

The actions taken by management under the Year 2000 Project Plans are intended
to significantly reduce AUSA's risk of a material business interruption based on
the Year 2000 issues. It should be noted that the Year 2000 computer problem,
and its resolution, is complex and multifaceted, and any company's success
cannot be conclusively known until the Year 2000 is reached. In spite of its
efforts or results, AUSA's ability to function unaffected to and through the
Year 2000 may be adversely affected by actions (or failure to act) of third
parties beyond our knowledge or control. It is anticipated that there may be
problems that will have to be resolved in the ordinary course of business on and
after the Year 2000. However, AUSA does not believe that the problems will have
a material adverse affect on AUSA's operations or financial condition.

                         Report of Independent Auditors



The Board of Directors
AUSA Life Insurance Company, Inc.


We have audited the accompanying statutory-basis balance sheets of AUSA Life
Insurance Company, Inc. as of December 31, 1998 and 1997 and the related
statutory-basis statements of operations, changes in capital and surplus, and
cash flows for each of the three years in the period ended December 31, 1998.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

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

As described in Note 1 to the financial statements, the Company presents its
financial statements in conformity with accounting practices prescribed or
permitted by the Department of Insurance of the State of New York, which
practices differ from generally accepted accounting principles. The variances
between such practices and generally accepted accounting principles also are
described in Note 1. The effects on the financial statements of these variances
are not reasonably determinable but are presumed to be material.

In our opinion, because of the effects of the matters described in the preceding
paragraph, the financial statements referred to above do not present fairly, in
conformity with generally accepted accounting principles, the financial position
of AUSA Life Insurance Company, Inc. at December 31, 1998 and 1997, or the
results of its operations or its cash flows for each of the three years in the
period ended December 31, 1998.

However, in our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of AUSA Life Insurance
Company, Inc. at December 31, 1998 and 1997, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1998 in conformity with accounting practices prescribed or permitted by the
Department of Insurance of the State of New York.

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

AUSA Life Insurance Company, Inc. ("the Company") is a stock life insurance
company and is 82 percent owned by First AUSA Life Insurance Company ("First
AUSA"), a wholly-owned subsidiary of AEGON USA, Inc. ("AEGON"), and 18 percent
owned by Veterans Life Insurance Company, an indirect wholly-owned subsidiary of
AEGON. AEGON is a wholly-owned subsidiary of AEGON N.V., a holding company
organized under the laws of The Netherlands. Effective September 24, 1993, First
AUSA purchased from The Dreyfus Corporation ("Dreyfus"), its entire interest in
Dreyfus Life Insurance Company and subsequently changed the name to AUSA Life
Insurance Company, Inc. On December 31, 1993, the Company entered into an
assumption reinsurance agreement with Mutual of New York ("MONY") to transfer
certain group pension business of MONY to the Company.

In July 1996, the Company completed a merger with International Life Investors
Insurance Company ("ILI"), a wholly-owned subsidiary of Life Investors Insurance
Company of America, another wholly-owned subsidiary of First AUSA, whereby ILI
was merged directly into the Company. The Company received assets of $688,233
and liabilities of $635,189. The difference between assets and liabilities was
transferred directly to capital and surplus. In accordance with National
Association of Insurance Commissioners ("NAIC") statutory accounting principles,
all prior period financial statements presented have been restated as if the
merger took place at the beginning of such periods. Historical book values
carried over from the separate companies to the combined entity.

On October 1, 1998, the Company completed a merger with First Providian Life and
Health Insurance Company ("FPLH"), an indirect wholly-owned subsidiary of
Commonwealth General Corporation which, in turn, is an indirect wholly-owned
subsidiary of AEGON, whereby FPLH was merged directly into the Company. The
accompanying financial statements give retroactive effect as if the merger had
occurred on January 1, 1996 in conformity with the practices of the NAIC and
accounting practices prescribed or permitted by the Department of Insurance of
the State of New York. This merger was accounted for under the pooling of
interests method of accounting and, accordingly, the historical book values
carried over from the separate companies to the Company.

1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

BASIS OF PRESENTATION

The preparation of financial statements of insurance companies requires
management to make estimates and assumptions that affect amounts reported in the
financial statements and accompanying notes. Actual results could differ from
those estimates.

Significant estimates and assumptions are utilized in the calculation of
aggregate policy reserves, policy and contract reserves, guarantee fund
assessment accruals and valuation allowances on investments. It is reasonably
possible that actual experience could differ from the estimates and assumptions
utilized which could have a material impact on the financial statements.

The accompanying financial statements have been prepared on the basis of
accounting practices prescribed or permitted by the Department of Insurance of
the State of New York ("Insurance Department"), which practices differ in some
respects from generally accepted accounting principles. The more significant of
these differences are as follows: (a) bonds are generally reported at amortized
cost rather than segregating the portfolio into held-to-maturity (reported at
amortized cost), available-for-sale (reported at fair value), and trading
(reported at fair value) classifications; (b) acquisition costs of acquiring new
business are charged to current operations as incurred rather than deferred and
amortized over the life of the policies; (c) policy reserves on traditional life
products are based on statutory mortality rates and interest which may differ
from reserves based on reasonable assumptions of expected mortality, interest,
and withdrawals which include a provision for possible unfavorable deviation
from such assumptions; (d) policy reserves on certain investment products use
discounting methodologies utilizing statutory interest rates rather than full
account values; (e) reinsurance amounts are netted against the corresponding
asset or liability rather than shown as gross amounts on the balance sheet; (f)
deferred income taxes are not provided for the difference between the financial
statement and income tax bases of assets and liabilities; (g) net realized gains
or losses attributed to changes in the level of interest rates in the market are
deferred and amortized over the remaining life of the bond or mortgage loan,
rather than recognized as gains or losses in the statement of operations when
the sale is completed; (h) declines in the estimated realizable value of
investments are provided for through the establishment of a formula-determined
statutory investment reserve (reported as a liability), changes to which are
charged directly to surplus, rather than through recognition in the statement of
operations for declines in value, when such declines are judged to be other than
temporary; (i) certain assets designated as "non-admitted assets" have been
charged to surplus rather than being reported as assets; (j) revenues for
universal life and investment products consist of premiums received rather than
policy charges for the cost of insurance, policy administration charges,
amortization of policy initiation fees and surrender charges assessed; (k)
pension expense is recorded as amounts are paid; (l) stock options settled in
cash are recorded as an expense of the Company's indirect parent rather than
charged to current operations; (m) adjustments to federal income taxes of prior
years

are charged or credited directly to unassigned surplus, rather than reported as
a component of expense in the statement of operations; and (n) gains or losses
on dispositions of business are charged or credited directly to unassigned
surplus rather than being reported in the statement of operations. The effects
of these variances have not been determined by the Company.

In 1998, the National Association of Insurance Commissioners (NAIC) adopted
codified statutory accounting principles ("Codification"). Codification will
likely change, to some extent, prescribed statutory accounting practices and may
result in changes to the accounting practices that the Company uses to prepare
its statutory-basis financial statements. Codification will require adoption by
the various states before it becomes the prescribed statutory basis of
accounting for insurance companies domesticated within those states.
Accordingly, before Codification becomes effective for the Company, the State of
New York must adopt Codification as the prescribed basis of accounting on which
domestic insurers must report their statutory-basis results to the Insurance
Department. At this time, it is unclear whether the State of New York will adopt
Codification. However, based on current guidance, management believes that the
impact of Codification will not be material to the Company's statutory-basis
financial statements.

CASH AND CASH EQUIVALENTS

For purposes of the statement of cash flows, the Company considers all highly
liquid investments with remaining maturity of one year or less when purchased to
be cash equivalents.

INVESTMENTS

Investments in bonds (except those to which the Securities Valuation Office of
the NAIC has ascribed a value), mortgage loans on real estate and short-term
investments are reported at cost adjusted for amortization of premiums and
accrual of discounts. Amortized costs for bonds and mortgage loans on real
estate that were acquired through the reinsurance agreement described earlier
were initially recorded at market value, consistent with the aforementioned
agreement and as prescribed by the Department of Insurance of the State of New
York. Amortization is computed using methods which result in a level yield over
the expected life of the security. The Company reviews its prepayment
assumptions on mortgage and other asset-backed securities at regular intervals
and adjusts amortization rates retrospectively when such assumptions are changed
due to experience and/or expected future patterns. Investments in preferred
stocks in good standing are reported at cost. Investments in preferred stocks
not in good standing are reported at the lower of cost or market. Common stocks
are carried at market. Real estate is reported at cost less allowances for

principal. Other invested assets consist principally of investments in various
joint ventures and are recorded at equity in underlying net assets. Other
"admitted assets" are valued, principally at cost, as required or permitted by
New York Insurance Laws.

Realized capital gains and losses are determined on the basis of specific
identification and are recorded net of related federal income taxes. The Asset
Valuation Reserve (AVR) is established by the Company to provide for anticipated
losses in the event of default by issuers of certain invested assets. These
amounts are determined using a formula prescribed by the NAIC and are reported
as a liability. The formula for the AVR provides for a corresponding adjustment
for realized gains and losses. Under a formula prescribed by the NAIC, the
Company defers, in the Interest Maintenance Reserve (IMR), the portion of
realized gains and losses on sales of fixed income investments, principally
bonds and mortgage loans, attributable to changes in the general level of
interest rates and amortizes those deferrals over the remaining period to
maturity of the security.

Interest income is recognized on an accrual basis. The Company does not accrue
income on bonds in default, mortgage loans on real estate in default and/or
foreclosure or which are delinquent more than twelve months, or real estate
where rent is in arrears for more than three months. Further, income is not
accrued when collection is uncertain. At December 31, 1998, 1997 and 1996, the
Company excluded investment income due and accrued of $216, $473 and $469,
respectively, with respect to such practices.

The Company uses interest rate swaps as part of its overall interest rate risk
management strategy for certain life insurance and annuity products. The net
interest effect of such swap transactions is reported as an adjustment of
interest income from the hedged items as incurred.

Deferred income for unrealized gains and losses on the securities valued at
market at the time of the assumption reinsurance agreement (described in Note 4)
are returned to MONY at the time of realization pursuant to the agreement.

AGGREGATE POLICY RESERVES

Life, annuity and accident and health benefit reserves are developed by
actuarial methods and are determined based on published tables using statutorily
specified interest rates and valuation methods that will provide, in the
aggregate, reserves that are greater than or equal to the minimum required by
law.

The aggregate policy reserves for life insurance policies are based principally
upon the 1941, 1958 and 1980 Commissioners' Standard Ordinary Mortality Tables.
The reserves are calculated using interest rates ranging from 2.50 to 6.50
percent and are computed principally on the Net Level Premium Valuation and the
Commissioners' Reserve Valuation Method. Reserves for universal life policies
are based on account balances adjusted for the Commissioners' Reserve Valuation
Method.

1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Deferred annuity reserves are calculated according to the Commissioners' Annuity
Reserve Valuation Method including excess interest reserves to cover situations
where the future interest guarantees plus the decrease in surrender charges are
in excess of the maximum valuation rates of interest. Reserves for immediate
annuities and supplementary contracts with life contingencies are equal to the
present value of future payments assuming interest rates ranging from 3.00 to
8.50 percent and mortality rates, where appropriate, from a variety of tables.

Accident and health policy reserves are equal to the greater of the gross
unearned premiums or any required midterminal reserves plus net unearned
premiums and the present value of amounts not yet due on both reported and
unreported claims.

POLICY AND CONTRACT CLAIM RESERVES

Claim reserves represent the estimated accrued liability for claims reported to
the Company and claims incurred but not yet reported through the statement date.
These reserves are estimated using either individual case-basis valuations or
statistical analysis techniques. These estimates are subject to the effects of
trends in claim severity and frequency. The estimates are continually reviewed
and adjusted as necessary as experience develops or new information becomes
available.

SEPARATE ACCOUNTS

Assets held in trust for purchases of separate account contracts and the
Company's corresponding obligation to the contract owners are shown separately
in the balance sheets. Income and gains and losses with respect to these assets
accrue to the benefit of the policyholders and, accordingly, the operations of
the separate accounts are not included in the accompanying financial statements.

Certain separate account assets and liabilities reported in the accompanying
financial statements contain contractual guarantees. Guaranteed separate
accounts represent funds invested by the Company for the benefit of individual
contract holders who are guaranteed certain returns as specified in the
contracts. Separate account asset performance different than guaranteed
requirements is either transferred to or received from the general account and
reported in the statements of operations. Guaranteed separate account assets and
liabilities are reported at estimated fair value except for certain government
and fixed-rate separate accounts, which are carried at amortized cost. The
assets and liabilities of the nonguaranteed separate accounts are carried at
estimated fair value.

STOCK OPTION PLAN

AEGON N.V. sponsors a stock option plan for eligible employees of the Company.
Under this plan, certain employees have indicated a preference to immediately
sell shares received as a result of their exercise of the stock options; in
these situations, AEGON N.V. has settled such options in cash rather than
issuing stock to these employees. These cash settlements are paid by the
Company, and AEGON N.V. subsequently reimburses the Company for such payments.
Under statutory accounting principles, the Company does not record any expense
related to this plan, as the expense is recognized by AEGON N.V. However, the
Company is allowed to record a deduction in the consolidated tax return filed by
the Company and certain affiliates.


2.   FAIR VALUES OF FINANCIAL INSTRUMENTS

Statement of Financial Accounting Standards (SFAS) No. 107, Disclosures about
Fair Value of Financial Instruments, requires disclosure of fair value
information about financial instruments, whether or not recognized in the
statutory-basis balance sheet, for which it is practicable to estimate that
value. SFAS No. 119, Disclosures About Derivative Financial Instruments and Fair
Value of Financial Instruments, requires additional disclosures about
derivatives. In cases where quoted market prices are not available, fair values
are based on estimates using present value or other valuation techniques. Those
techniques are significantly affected by the assumptions used, including the
discount rate and estimates of future cash flows. In that regard, the derived
fair value estimates cannot be substantiated by comparisons to independent
markets and, in many cases, could not be realized in immediate settlement of the
instrument. SFAS No. 107 and No. 119 exclude certain financial instruments and
all nonfinancial instruments from their disclosure requirements and allow
companies to forego the disclosures when those estimates can only be made at
excessive cost. Accordingly, the aggregate fair value amounts presented do not
represent the underlying value of the Company.

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

     Cash and short-term investments: The carrying amounts reported in the
     statutory-basis balance sheet for these instruments approximate their fair
     values.

     Investment securities: Fair values for fixed maturity securities (including
     redeemable preferred stocks) are based on quoted market prices, where
     available. For fixed maturity securities not actively traded, fair values
     are estimated using values obtained

   from independent pricing services or, in the case of private placements, are
   estimated by discounting expected future cash flows using a current market
   rate applicable to the yield, credit quality, and maturity of the
   investments. The fair values for equity securities are based on quoted market
   prices.

   Mortgage loans and policy loans: The fair values for mortgage loans are
   estimated utilizing discounted cash flow analyses, using interest rates
   reflective of current market conditions and the risk characteristics of the
   loans. The fair value of policy loans is assumed to equal its carrying value.

   Investment contracts: Fair values for the Company's liabilities under
   investment-type insurance contracts are estimated using discounted cash flow
   calculations, based on interest rates currently being offered for similar
   contracts with maturities consistent with those remaining for the contracts
   being valued.

   Interest rate swaps: Estimated fair value of interest rate swaps are based
   upon the pricing differential for similar swap agreements.

Fair values for the Company's insurance contracts other than investment
contracts are not required to be disclosed. However, the fair values of
liabilities under all insurance contracts are taken into consideration in the
Company's overall management of interest rate risk, which minimizes exposure to
changing interest rates through the matching of investment maturities with
amounts due under insurance contracts.

The following sets forth a comparison of the fair values and carrying values of
the Company's financial instruments subject to the provisions of SFAS No. 107
and No. 119:

3. INVESTMENTS (CONTINUED)

During 1998, the Company issued mortgage loans with interest rates ranging from
6.55% to 8.49%. The maximum percentage of any one loan to the value of the
underlying real estate at origination was 79%. No mortgage loans were non-income
producing for the previous twelve months and, accordingly, no accrued interest
related to these mortgage loans was excluded from investment income. The Company
requires all mortgage loans to carry fire insurance equal to the value of the
underlying property.

During 1998, 1997 and 1996, there were $2,796, $4,427 and $28,929, respectively,
in foreclosed mortgage loans that were transferred to real estate. At December
31, 1998 and 1997, the Company held a mortgage loan loss reserve in the asset
valuation reserve of $34,083 and $20,191, respectively. The mortgage loan
portfolio is diversified by geographic region and specific collateral property
type as follows:

At December 31, 1998, the Company had no investments, excluding U. S. Government
guaranteed or insured issues, which individually represented more than ten
percent of capital and surplus and the asset valuation reserve.

The Company utilized an interest rate swap agreement as part of its efforts to
hedge and manage fluctuations in the market value of its investment portfolio
attributable to changes in general interest rate levels and to manage duration
mismatch of assets and liabilities. The contract or notional amounts of those
instruments reflect the extent of involvement in the various types of financial
instruments.

3. INVESTMENTS (CONTINUED)

The Company's exposure to credit risk is the risk of loss from a counterparty
failing to perform according to the terms of the contract. That exposure
includes settlement risk (i.e., the risk that the counterparty defaults after
the Company has delivered funds or securities under terms of the contract) that
would result in an accounting loss and replacement cost risk (i.e., the cost to
replace the contract at current market rates should the counterparty default
prior to settlement date). Credit loss exposure resulting from nonperformance by
a counterparty for commitments to extend credit is represented by the
contractual amounts of the instruments.

At December 31, 1998, the Company held no derivative instruments. At December
31, 1998 and 1997, the Company's outstanding financial instruments with on and
off-balance sheet risks, shown in notional amounts, are summarized as follows:

4. REINSURANCE

The Company reinsures portions of risk on certain insurance policies which
exceed its established limits, thereby providing a greater diversification of
risk and minimizing exposure on larger risks. The Company remains contingently
liable with respect to any insurance ceded, and this would become an actual
liability in the event that the assuming insurance company became unable to meet
its obligation under the reinsurance treaty.

Premiums earned reflect the following reinsurance assumed and ceded amounts for
the year ended December 31:

4. REINSURANCE (CONTINUED)

The Company received reinsurance recoveries in the amounts of $2,493, $1,992 and
$1,758 during 1998, 1997 and 1996, respectively.

The aggregate reserves for policies and contracts were reduced for reserve
credits for reinsurance ceded at December 31, 1998 and 1997 of $143,819 and
$153,092, respectively.

On December 31, 1993, the Company and MONY entered into an assumption
reinsurance agreement whereby all of the general account liabilities were
novated to the Company from MONY as state approvals were received.

In accordance with the agreement, MONY will receive payments relating to the
performance of the assets and liabilities that exist at the date of closing for
a period of nine years. These payments will be reduced for certain
administrative expenses as defined in the agreement. The Company will recognize
operating gains and losses on renewal premiums received after December 31, 1993
of the business in-force at December 31, 1993, and on all new business written
after that date. At the end of nine years from the date of closing, the Company
will purchase from MONY the remaining transferred business inforce based upon a
formula described in the agreement. At December 31, 1998 and 1997, the Company
owed MONY $52,837 and $56,952, respectively, which represents the amount earned
by MONY under the gain sharing calculation and certain fees for investment
management services for the respective years.

In connection with the transaction, MONY purchased $150,000 and $50,000 in
Series A and Series B notes, respectively, of AEGON. The proceeds were used to
enhance the surplus of the Company. Both the Series A and Series B notes bear a
market rate of interest and mature in nine years from the date of closing.

AEGON provides general and administrative services for the transferred business
under a related agreement with MONY. The agreement specifies prescribed rates
for expenses to administer the business up to certain levels. In addition, AEGON
also provides investment management services on the assets underlying the new
business written by the Company while MONY continues to provide investment
management services for assets supporting the remaining policy liabilities which
were transferred at December 31, 1993.

5. INCOME TAXES

For federal income tax purposes, the Company joins in a consolidated tax return
filing with certain affiliated companies. Under the terms of a tax-sharing
agreement between the Company and its affiliates, the Company computes federal
income tax expense as if it were filing a separate income tax return, except
that tax credits and net operating loss carryforwards are determined on the
basis of the consolidated group. Additionally, the alternative minimum tax is
computed for the consolidated group and the resulting tax, if any, is allocated
back to the separate companies on the basis of the separate companies'
alternative minimum taxable income.

Federal income tax expense differs from the amount computed by applying the
statutory federal income tax rate to gain from operations before federal income
tax expense and net realized capital gains (losses) on investments primarily due
to differences in the statutory and tax treatment of certain investments,
deferred policy acquisition costs, stock options exercised, dividends received
deduction, carryforward (utilization) of operating loss, IMR amortization, and
certain adjustments related to the agreement between MONY and the Company. These
adjustments caused the Company to calculate federal income tax expense using
alternative minimum tax requirements in 1998.

Federal income tax expense differs from the amount computed by applying the
statutory federal income tax rate to net realized capital gains (losses) on
investments due to the agreement between MONY and the Company, as discussed in
Note 4 to the financial statements. In accordance with this agreement, these
gains and losses are included in the net payments MONY will receive relating to
the performance of the assets that existed at the date of closing. Accordingly,
income taxes relating to gains and losses on such assets are not provided for on
the income tax return filed by the Company.

Prior to 1984, as provided for under the Life Insurance Company Tax Act of 1959,
a portion of statutory income was not subject to current taxation but was
accumulated for income tax purposes in a memorandum account referred to as the
policyholders' surplus account. No federal income taxes have been provided for
in the financial statements on income deferred in the policyholders' surplus
account ($2,427 at December 31, 1998). To the extent dividends are paid from the
amount accumulated in the policyholders' surplus account, net earnings would be
reduced by the amount of tax required to be paid. Should the entire amount in
the policyholders' surplus account become taxable, the tax thereon computed at
current rates would amount to approximately $849.

At December 31, 1998, the Company had net operating loss carryforwards of
approximately $8,514 which expire through 2011.

In 1998, the Company reached a final settlement with the Internal Revenue
Service for years 1993 through 1995 resulting in no tax due or refunded.

6. POLICY AND CONTRACT ATTRIBUTES

A portion of the Company's policy reserves and other policyholders' funds relate
to liabilities established on a variety of the Company's products that are not
subject to significant mortality or morbidity risk; however, there may be
certain restrictions placed upon the amount of funds that can be withdrawn
without penalty. The amount of reserves on these products, by withdrawal
characteristics, are summarized as follows:

Reserves on the Company's traditional life products are computed using mean
reserving methodologies. These methodologies result in the establishment of
assets for the amount of the net valuation premiums that are anticipated to be
received between the policy's paid-through date to the policy's next anniversary
date. At December 31, 1998 and 1997, these assets (which are reported as
premiums deferred and uncollected) and the amounts of the related gross premiums
and loadings, are as follows:

At December 31, 1998 and 1997, the Company had insurance in force aggregating
$474,471 and $597,855, respectively, in which the gross premiums are less than
the net premiums required by the valuation standards established by the
Department of Insurance of the State of New York. The Company established policy
reserves of $1,348 and $1,476 to cover these deficiencies at December 31, 1998
and 1997, respectively.

7. DIVIDEND RESTRICTIONS

The Company is subject to certain limitations relative to statutory surplus,
imposed by the State of New York, on the payment of dividends to its parent
company.

8. RETIREMENT AND COMPENSATION PLANS

The Company's employees participate in a qualified benefit pension plan
sponsored by AEGON. The Company has no legal obligation for the plan. The
Company recognizes pension expense equal to its allocation from AEGON. The
pension expense is allocated among the participating companies based on the FASB
87 expense as a percent of salaries. The benefits are based on years of service
and the employee's compensation during the highest five consecutive years of
employment. The Company was allocated $4, $0 and $13 of pension expense for the
years ended December 31, 1998, 1997 and 1996, respectively. The plan is subject
to the reporting and disclosure requirements of the Employee Retirement Income
Security Act of 1974.

The Company's employees also participate in a contributory defined contribution
plan sponsored by AEGON which is qualified under Section 401(k) of the Internal
Revenue Service Code. Employees of the Company who customarily work at least
1,000 hours during each calendar year and meet the other eligibility
requirements are participants of the plan. Participants may elect to contribute
up to fifteen percent of their salary to the plan. The Company will match an
amount up to three percent of the participant's salary. Participants may direct
all of their contributions and plan balances to be invested in a variety of
investment options. The plan is subject to the reporting and disclosure
requirements of the Employee Retirement Income Security Act of 1974. The Company
was allocated $9, $12 and $21 of expense for the years ended December 31, 1998,
1997 and 1996, respectively.

AEGON sponsors supplemental retirement plans to provide the Company's senior
management with benefits in excess of normal pension benefits. The plans are
noncontributory and benefits are based on years of service and the employee's
compensation level. The plans are unfunded and nonqualified under the Internal
Revenue Service Code. In addition, AEGON has established incentive deferred
compensation plans for certain key employees of the Company. AEGON also sponsors
an employee stock option plan for individuals employed at least three years and
a stock purchase plan for its producers, with the participating affiliated
companies establishing their own eligibility criteria, producer contribution
limits and company matching formula. These plans have been accrued or funded as
deemed appropriate by management of AEGON and the Company.

In addition to pension benefits, the Company participates in plans sponsored by
AEGON that provide postretirement medical, dental and life insurance benefits to
employees meeting certain eligibility requirements. Portions of the medical and
dental plans are contributory. The expenses of the postretirement plans
calculated on the pay-as-you-go basis are charged to affiliates in accordance
with an intercompany cost sharing arrangement. The Company expensed $4, $2 and
$2 for the years ended December 31, 1998, 1997 and 1996, respectively.

9.  RELATED PARTY TRANSACTIONS

In accordance with an agreement between AEGON and the Company, AEGON will ensure
the maintenance of certain minimum tangible net worth, operating leverage and
liquidity levels of the Company, as defined in the agreement, through the
contribution of additional capital by the Company's parent as needed.

The Company shares certain officers, employees and general expenses with
affiliated companies.

The Company receives data processing, investment advisory and management,
marketing and administration services from certain affiliates. During 1998, 1997
and 1996, the Company paid $5,650, $7,330 and $5,739, respectively, for these
services, which approximates their costs to the affiliates.

Payable to affiliates and intercompany borrowings bear interest at the thirty-
day commercial paper rate of 4.95% at December 31, 1998. During 1998, 1997 and
1996, the Company paid net interest of $232, $142 and $29, respectively, to
affiliates.

10. COMMITMENTS AND CONTINGENCIES

The Company has issued Trust GIC contracts to plan sponsors totaling $153,146 at
December 31, 1998, pursuant to terms under which the plan sponsor retains
ownership of the assets related to these contracts. The Company guarantees
benefit responsiveness in the event that plan benefit requests and other
contractual commitments exceed plan cash flows. The plan sponsor agrees to
reimburse the Company for such benefit payments with interest, either at a fixed
or floating rate, from future plan and asset cash flows. In return for this
guarantee, the Company receives a premium which varies based on such elements as
benefit responsive exposure and contract size. The Company underwrites the plans
for the possibility of having to make benefit payments and also must agree to
the investment guidelines to ensure appropriate credit quality and cash flow
matching. The assets and liabilities relating to such contracts are not
recognized in the Company's statutory-basis financial statements.

The Company is a party to legal proceedings incidental to its business. Although
such litigation sometimes includes substantial demands for compensatory and
punitive damages, in addition to contract liability, it is management's opinion,
after consultation with counsel and a review of available facts, that damages
arising from such demands will not be material to the Company's financial
position.

10. COMMITMENTS AND CONTINGENCIES (CONTINUED)

The Company is subject to insurance guaranty laws in the states in which it
writes business. These laws provide for assessments against insurance companies
for the benefit of policyholders and claimants in the event of insolvency of
other insurance companies. In accordance with the purchase agreement,
assessments related to periods prior to the purchase of the Company will be paid
by Dreyfus and assessments attributable to business reinsured from MONY for
premiums received prior to the date of the transaction will be paid by MONY (see
Note 1). The Company will be responsible for assessments, if any, attributable
to premium income after the date of purchase. Assessments are charged to
operations when received by the Company except where right of offset against
other taxes paid is allowed by law; amounts available for future offsets are
recorded as an asset on the Company's balance sheet. Potential future
obligations for unknown insolvencies are not determinable by the Company. The
future obligation has been based on the most recent information available from
the National Organization of Life and Health Insurance Guaranty Associations.
The guaranty fund expense was $126, $586 and $246 for the years ended December
31, 1998, 1997 and 1996, respectively.

11. YEAR 2000 (UNAUDITED)

The term Year 2000 issue generally refers to the improper processing of dates
and incorrect date calculations that might occur in computer software and
hardware and embedded systems as the Year 2000 is approached. The use of
computer programs that rely on two-digit date fields to perform computations and
decision-making functions may cause systems to malfunction when processing
information involving dates after 1999. For example, any computer software that
has date-sensitive coding might recognize a code of 00 as the year 1900 rather
than the year 2000.

The Company has developed a Year 2000 Project Plan (the Plan) to address the
Year 2000 issue as it affects the Company's internal Information Technology
("IT") and non-IT systems, and to assess Year 2000 issues relating to third
parties with whom the Company has critical relationships.

The Plan for addressing internal systems generally includes an assessment of
internal IT and non-IT systems and equipment affected by the Year 2000 issue;
definition of strategies to address affected systems and equipment; remediation
of identified systems and equipment; internal testing and certification that
each internal system is Year 2000 compliant; and a review of existing and
revised business resumption and contingency plans to address potential Year 2000
issues. The Company has remediated and tested substantially all of its mission-
critical internal IT systems as of December 31, 1998. The Company continues to
remediate and test certain non-critical internal IT systems, internal non-IT
systems and will continue with a revalidation testing program throughout 1999.

11. YEAR 2000 (UNAUDITED) (CONTINUED)

The Company's Year 2000 issues are more complex because a number of its systems
interface with other systems not under the Company's control. The Company's most
significant interfaces and uses of third-party vendor systems are in the bank,
financial services and trust areas. The Company utilizes various banks to handle
numerous types of financial and sales transactions. Several of these banks also
provide trustee and custodial services for the Company's investment holdings and
transactions. These services are critical to a financial services company such
as the Company as its business centers around cash receipts and disbursements to
policyholders and the investment of policyholder funds. The Company has received
written confirmation from its vendor banks regarding their status on Year 2000.
The banks indicate their dedication to resolving any Year 2000 issues related to
their systems and services prior to December 31, 1999. The Company anticipates
that a considerable effort will be necessary to ensure that its corrected or new
systems can properly interface with those business partners with whom it
transmits and receives data and other information (external systems). The
Company has undertaken specific testing regimes with these third-party business
partners and expects to continue working with its business partners on any
interfacing of systems. However, the timing of external system compliance cannot
currently be predicted with accuracy because the implementation of Year 2000
readiness will vary from one company to another.

The Company does have some exposure to date-sensitive embedded technology such
as micro-controllers, but the Company views this exposure as minimal. Unlike
other industries that may be equipment intensive, like manufacturing, the
Company is a life insurance and financial services organization providing
insurance, annuities and pension products to its customers. As such, the primary
equipment and electronic devices in use are computers and telephone related
equipment. This type of hardware can have date-sensitive embedded technology
which could have Year 2000 problems. Because of this exposure, the Company has
reviewed its computer hardware and telephone systems, with assistance from the
applicable vendors, and has upgraded, or replaced, or is in the process of
replacing any equipment that will not properly process date-sensitive data in
the Year 2000 or beyond.

For the Company, a reasonably likely worst case scenario might include one or
more of the Company's significant policyholder systems being non-compliant. Such
an event could result in a material disruption of the Company's operations.
Specifically, a number of the Company's operations could experience an
interruption in the ability to collect and process premiums or deposits, process
claim payments, accurately maintain policyholder information, accurately
maintain accounting records, and/or perform adequate customer service. Should
the worst case scenario occur, it could, dependent upon its duration, have a
material impact on the Company's business and financial condition. Simple
failures can

be repaired and returned to production within a matter of hours with no material
impact. Unanticipated failures with a longer service disruption period could
have a more serious impact. For this reason, the Company is placing significant
emphasis on risk management and Year 2000 business resumption contingency
planning in 1999 by modifying its existing business resumption and disaster
recovery plans to address potential Year 2000 issues.

The actions taken by management under the Year 2000 Project Plans are intended
to significantly reduce the Company's risk of a material business interruption
based on the Year 2000 issues. It should be noted that the Year 2000 computer
problem, and its resolution, is complex and multifaceted, and any company's
success cannot be conclusively known until the Year 2000 is reached. In spite of
its efforts or results, the Company's ability to function unaffected to and
through the Year 2000 may be adversely affected by actions (or failure to act)
of third parties beyond our knowledge or control. It is anticipated that there
may be problems that will have to be resolved in the ordinary course of business
on and after the Year 2000. However, the Company does not believe that the
problems will have a material adverse affect on the Company's operations or
financial condition.

ITEM 27. NUMBER OF CONTRACT OWNERS
            
 As of February 28, 1999 there were 200 contract owners.     
    
ITEM 28. INDEMNIFICATION
 
 The New York Code (Section 721 et seq.) provides for permissive indemnifica-
tion in certain situations, mandatory indemnification in other situations, and
prohibits indemnification in certain situations. The Code also specifies pro-
cedures for determining when indemnification payments can be made.
 
 Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "1933 Act"), may be permitted to directors, offi-
cers, and controlling persons of the Depositor pursuant to the foregoing pro-
visions, or otherwise, the Depositor has been advised that, in the opinion of
the securities and Exchange Commission, such indemnification is against public
policy as expressed in the 1933 Act, and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than
the payment by the Depositor of expenses incurred or paid by a director, offi-
cer, or controlling person in connection with the securities being regis-
tered), the Depositor 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 1933 Act and will be governed by the final adjudi-
cation of such issue.
 
ITEM 29. PRINCIPAL UNDERWRITERS
 
 (a) None.
 
 (b) Not Applicable.
 
ITEM 30. LOCATION OF ACCOUNTS AND RECORDS
   
 The books, accounts and other documents required by Section 31(a) under the
Investment Company Act and the rules promulgated thereunder will be maintained
in the physical possession of The Continuum Company, Inc., Kansas City, Mis-
souri, The Vanguard Group, Inc., Valley Forge, Pennsylvania and AUSA Life In-
surance Company, Inc., New York, New York.

RE:  AUSA Life Insurance Company, Inc. Separate Account B-- Opinion and Consent

To Whom It May Concern:
         
     This opinion and consent is furnished in connection with the filing of 
Post-Effective Amendment No. 5 to Registration Statement on Form N-4 under the
Securities Act of 1933, as amended (the "1933 Act"), and Amendment No. 19 to the
Registration Statement on Form N-4 under the Investment Company Act of 1940, as
amended (the "1940 Act"), File No. 811-6298 (the "Registration Statement"), of
AUSA Life Insurance Company, Inc. Separate Account B (Vanguard) ("Separate
Account B"). Separate Account B receives and invests premiums allocated to it
under a group flexible premium multi-funded annuity contract, the Vanguard
Variable Annuity Plan Contract (the "Annuity Contract"). The Annuity Contract is
offered in the manner described in the prospectus contained in the Registration
Statement (the "Prospectus").     
   
     In my capacity as legal adviser to AUSA Life Insurance Company, Inc. ("AUSA
Life"), I hereby confirm the establishment of Separate Account B as a separate
account for assets applicable to the Annuity Contract, pursuant to the
provisions of Section 4240 of the New York Insurance Statutes. In addition, I
have made such examination of the law in addition to consultation with outside
counsel and have examined such corporate records and such other documents as I
consider appropriate as a basis for the opinion hereinafter expressed. On the
basis of such examination, it is my professional opinion that:     

1.   AUSA Life Insurance Company, Inc. is a corporation duly organized and
     validly existing under the laws of the State of New York.
   
2.   Separate Account B is an account maintained by AUSA Life Insurance Company,
     Inc. pursuant to the laws of the State of New York, under which income,
     capital gains, and capital losses incurred on the assets of Separate
     Account B will be credited to or charged against the assets of Separate
     Account B, without regard to the income, capital gains or capital losses
     arising out of any other business which AUSA Life Insurance Company, Inc.
     may conduct.     
   
3.   Assets allocated to Separate Account B are owned by AUSA Life Insurance
     Company, Inc. The assets in Separate Account B attributable to the Annuity
     Contract generally will not be chargeable with liabilities arising out of
     any other business which AUSA Life Insurance Company, Inc. may conduct. The
     assets of Separate Account B will be available to cover the general
     liabilities of AUSA Life Insurance Company, Inc. only to the extent that
     the assets     
<PAGE>
 
     of Separate Account B exceed the liabilities arising under the Annuity
     Contracts.

4.   The Annuity Contracts will have been duly authorized by AUSA Life Insurance
     Company, Inc. and, when sold in jurisdictions authorizing such sales, in
     accordance with the Registration Statement, will constitute validly issued
     and binding obligations of AUSA Life Insurance Company, Inc. in accordance
     with their terms.

5.   Owners of the Annuity Contracts, as such, will not be subject to any
     deductions, charges, or assessments imposed by AUSA Life Insurance Company,
     Inc. other than those provided in the Annuity Contract.

I hereby consent to the use of this opinion as an exhibit to the Registration
Statement and to the reference to my name under the heading "Legal Matters" in
the Prospectus.

Very truly yours,
