HOW THE CONTRACT WORKS

The Contract basically works in two ways.
    
1ST, the Contract can help you save for retirement because you can invest in up
  to 13 investment choices and pay no federal income taxes on any earnings until
  you withdraw them.  You do this during what we call the "ACCUMULATION PHASE"
  of the Contract.  The Accumulation Phase begins when you buy a Contract (we
  call this the "EFFECTIVE DATE") and continues to the date you begin receiving
  annuity payments (we call that the "ANNUITY DATE").  During the Accumulation
  Phase, if you invest in the Fixed Fund Account, you will earn a fixed rate of
  interest (not less than 3%) that we declare periodically.  If you invest in
  the Variable Fund Accounts, your investment return will vary up or down
  depending on the performance of the corresponding Funds.     
    
2ND, the Contract can help you plan for retirement because you can use it to
  receive retirement income for life, or for a pre-set number of years, by
  selecting one of the annuity payment options described on page 17A.  You do
  this during what we call the "DISTRIBUTION PHASE" of the Contract.  The
  Distribution Phase is the period beginning on and continuing after the Annuity
  Date.  During the Distribution Phase, if you select a fixed annuity payment
  option, we guarantee the amount of your payments, which will remain fixed.  If
  you select a variable annuity payment option, based on up to four of the
  Variable Fund Accounts, the amount of your payments will vary up or down
  depending on the performance of the corresponding Funds.     

You can use the Contract with a "NONQUALIFIED PLAN" or a "QUALIFIED PLAN."
  .  A Nonqualified Plan is a retirement plan that permits deferral of federal
     income tax on earnings.
    
  .  A Qualified Plan is a personal retirement savings plan, such as an
     individual retirement annuity ("IRA") or tax-sheltered annuity ("TSA") that
     permits (1) money to be contributed on a pre-federal income tax basis, and
     (2) deferral of federal income tax on earnings.     

The timeline below illustrates how you might use your Contract.

(1)  We may deduct a charge of up to 7% from transfers or withdrawals from the
     Fixed Fund Account depending upon how long the money transferred or
     withdrawn has been on deposit with us.  (See "Fixed Fund Account Withdrawal
     Charge.")     
(2)  Applies annually during the Accumulation Phase.
(3)  Applies only to the Variable Fund Accounts.
(4)  The figures shown in the table are as of each Fund's most recently
     completed fiscal year.  These expenses are reflected in the daily price of
     each Fund's shares.
(5)  USAA Life has agreed to assume the expenses of the USAA Life Investment
     Trust Funds that exceed, annually, .65% of the monthly average net assets
     of the World Growth Fund, .70% of the monthly average net assets of the
     Aggressive Growth Fund, 1.10% of the monthly average net assets of the
     International Fund, and .35% of the monthly average net assets of each
     other Fund. We may stop assuming these expenses by giving the USAA Life
     Investment Trust 120 days advance notice.  Absent our agreement to assume
     these expenses, the expenses of the USAA Life Money Market, Income, Growth
     & Income, World Growth, Diversified Assets, Aggressive Growth, and
     International Funds for the 1998 fiscal year would have been:  .80%, .55%,
     .37%, .66%, .45%, .84% and 1.35%, respectively.  Bankers Trust has agreed
     to reimburse the BT Equity 500 Index Fund, BT Small Cap Index Fund, and BT
     EAFE(R) Equity Index Fund to the extent their total operating expenses
     exceed 0.30%, 0.45%, and 0.65%, respectively.   Bankers Trust may stop
     reimbursing these Funds at any time. Without this reimbursement
     arrangement, the expenses for the 1998 fiscal year for the BT Equity 500
     Index Fund, BT Small Cap Index Fund, and BT EAFE(R) Equity Index Fund would
     have been 1.19%, 1.58% and 1.66% respectively.

Fixed Fund Account
- ------------------
    
THE FIXED FUND ACCOUNT IS NOT AVAILABLE TO RESIDENTS OF MARYLAND, MASSACHUSETTS,
PENNSYLVANIA, OREGON, OR WASHINGTON. THE FIXED FUND ACCOUNT ALSO IS NOT
AVAILABLE WITH CONTRACTS ISSUED UNDER THE TEXAS OPTIONAL RETIREMENT PROGRAM
("ORP"). AMOUNTS INVESTED IN THE FIXED FUND ACCOUNT AS WELL AS AMOUNTS
SUPPORTING FIXED ANNUITY PAYMENTS ARE PART OF OUR GENERAL ACCOUNT ("GENERAL
ACCOUNT"). WE HAVE NOT REGISTERED THE INTERESTS IN THE GENERAL ACCOUNT WITH THE
SEC, NOR HAVE WE REGISTERED THE GENERAL ACCOUNT WITH THE SEC AS AN INVESTMENT
COMPANY. THE STAFF OF THE SEC HAS NOT REVIEWED THE DISCLOSURES IN THIS
PROSPECTUS THAT RELATE TO THE FIXED FUND ACCOUNT OR FIXED ANNUITY PAYMENTS. AT
THE SAME TIME, WE HAVE LEGAL RESPONSIBILITY FOR THE ACCURACY AND COMPLETENESS OF
THIS PROSPECTUS.     

The money that you invest in or transfer to the Fixed Fund Account during any
month ("NEW MONEY") will earn interest at what we call the "NEW MONEY INTEREST
RATE." We declare this rate of interest at the beginning of each month and it
applies to all New Money that we receive that month.  We credit the New Money
Interest Rate  through the end of the current calendar year in which you invest
the New Money in the Fixed Fund Account.

The Contract Value in your Fixed Fund Account that is not attributable to New
Money will earn interest at what we call the "PORTFOLIO INTEREST RATE."  We
declare this rate of interest at the beginning of each calendar year for that
year.  We also may declare, before the beginning of each month, additional
interest on all amounts in the Fixed Fund Account other than New Money.

We guarantee both the New Money Interest Rate and the Portfolio Interest Rate.
These rates will never fall below a minimum effective annual rate of 3% (or
higher rate, if required by state law).
    
The New Money Interest Rate may be higher or lower than the Portfolio Interest
Rate.  As a result, there may be occasions when you could earn a higher rate of
interest by transferring amounts that are no longer subject to a withdrawal
charge out of the Fixed Fund Account to a Variable Fund Account, and then
transferring the amount back into the Fixed Fund Account.  By so doing, the
amount transferred would be considered New Money and would earn interest at the
New Money Interest Rate, which could be higher than the Portfolio Interest Rate,
for the remainder of the year in which the transfer occurred.  You should be
aware, however, that because any amounts transferred in this manner would be
considered New Money, they would again be subject to the Fixed Fund Account
Withdrawal Charge.  (See "Charges and Deductions - Fixed Fund Account Withdrawal
Charge.")     

Our General Account assets support our obligations with respect to the Fixed
Fund Account, and also support our obligations under other insurance contracts.
We own the investments  purchased with amounts allocated to the Fixed Fund
Account.   You have no legal rights in such investments.

SPECIAL SERVICES

To begin or end any of the special services described below, simply call or
write to us at the phone number or address on the cover of this prospectus.  We
will provide you with instructions and a copy of any forms you need to complete.
During the Accumulation Phase, we may suspend, terminate, or modify the dollar
cost averaging or systematic withdrawal programs by giving you 30 days advance
notice.  The suspension or termination of a program will not affect you if you
are already in a program.

Automatic Payment Plan
- ----------------------

This plan allows you to make regular premium payments from your checking or
savings account. We will automatically withdraw the amount you specify and
invest it according to your instructions on file with us.

Dollar Cost Averaging Program
- -----------------------------
    
This program allows you to regularly transfer money from one or more Variable
Fund Accounts (for example, the USAA Life Money Market Fund Account) to your
other investment choices.  We will automatically transfer the amount or
percentage you specify and invest it according to your instructions on file with
us.   The program does not permit transfers from the Fixed Fund Account.  The
program is available only during the Accumulation Phase.     

To begin the program, you must have at least $5,000 in the Variable Fund Account
from which you intend to transfer Contract Value.  The minimum amount that you
may transfer is $100, or, if less, the remaining balance of your investment in
the Variable Fund Account from which you are transferring.  You must schedule
transfers over a period of at least 12 months at monthly, quarterly, or
semiannual intervals.

Transfers under the program do not count toward your limit of six transfers per
Contract Year.  A "CONTRACT YEAR" is the 12-month period following the Effective
Date and each 12-month period thereafter.
    
Currently, there is no charge for this program.  We reserve the right to
suspend, terminate or modify the offering of the program.     

Systematic Withdrawal Program
- -----------------------------

This program allows you to withdraw pre-set amounts monthly, quarterly,
semiannually, or annually from the Fixed and/or Variable Fund Accounts.  We will
withdraw the amounts you specify proportionately from all of your investment
choices or only from the investment choices you specify. You may change the
amount or frequency of withdrawals once each Contract Year.

You must have a minimum Contract Value of $20,000 to participate in the program
($5,000 if the Contract funds a Qualified Plan).  The minimum amount you may
withdraw from the Fixed or a Variable Fund Account is $250, or, if less, the
remainder of the Account.

A withdrawal charge and federal income taxes and penalties may apply to your
systematic withdrawals. See "Charges and Deductions - Fixed Fund Account
Withdrawal Charge" and "Tax Information."  You should seek the advice of a tax
adviser before choosing this program.

Currently, there is no charge for this program.  We reserve the right, however,
to charge for this program during the Accumulation Phase of the Contract.  We do
not intend to profit from any such charge.

YOUR CONTRACT VALUE

Your Contract Value during the Accumulation Phase equals the sum of the values
you have invested in the Fixed and Variable Fund Accounts.

Fixed Fund Account Value
- ------------------------

The value of your Contract in the Fixed Fund Account ("FIXED FUND ACCOUNT
VALUE") on any business day will equal:
    
  .  the sum of premium payments you invested in the Fixed Fund Account;
  .  plus accumulated interest;
  .  plus any amounts transferred from the Variable Fund Accounts to the Fixed
     Fund Account; 
  .  less the Fixed Fund Account portion of any Contract Maintenance Charges;
  .  less any withdrawals or transfers of value; and
  .  less any applicable premium tax.

Variable Fund Account Value
- ---------------------------

We measure the value of your Variable Fund Accounts ("VARIABLE FUND ACCOUNT
VALUE") using a unit of measure we call the "ACCUMULATION UNIT." When you invest
in a Variable Fund Account, we credit your Contract with a number of
Accumulation Units.  Your Variable Fund Account Value on any business day will
equal the number of Accumulation Units credited to you multiplied by the price
of the Accumulation Unit on that date.

     EXAMPLE:
    
     You pay us $6,000 in premium on Wednesday.  You allocate the premium to the
     USAA Life Growth and Income Fund Account.  When the New York Stock Exchange
     closes that day, we determine that the value of an Accumulation Unit for
     that Variable Fund Account is $20.00.  We then divide your $6,000 payment
     by $20.00 and credit your Contract with 300 Accumulation Units.     

We calculate the value of an Accumulation Unit ("ACCUMULATION UNIT VALUE") for
each Variable Fund Account after the New York Stock Exchange closes each
business day based on the formula below.  To receive a quotation of daily
Accumulation Unit Values, call us at 1-800-531-4265.

To calculate the Accumulation Unit Value of a Variable Fund Account each
business day, we:
    
  .  calculate the change in market value from the previous day for the
     underlying fund.
  .  subtract insurance charges such as mortality and expense risk charge and
     administrative charge.
  .  add or subtract the result to the prior day's Accumulation Unit Value.     

Minimum Contract Value
- ----------------------
    
If your Contract Value during the Accumulation Phase is less than $1,000 and we
haven't received premium payments for two years, we may cancel your Contract.
This minimum does not apply to Contracts issued in connection with Qualified
Plans. We will notify you 30 days before we cancel your Contract.  You will have
an opportunity to satisfy the minimum requirement before we cancel your
Contract.  If we cancel your Contract, we will pay your contract value in a lump
sum and we will have no further obligations.     

ANNUITY BENEFITS

You may choose to receive annuity payments during the Distribution Phase. We
will pay you according to the annuity payment option or "DISTRIBUTION OPTION"
you select.  Payments will start on the Annuity Date and will continue for the
period specified in the Distribution Option you select.

Annuity Date
- ------------
    
You select your Annuity Date when you apply for a Contract.  If you are using
your Contract as a Qualified Plan, the Annuity Date may not be later than the
date required by federal income tax law.  (See  "Tax Information.")  If you are
using your Contract as a Nonqualified Plan, the Annuity Date may not be later
than the Annuitant's 95th birthday.  The Annuity Date must also be at least six
months after the Effective Date of your Contract, unless we choose to waive this
requirement.  You may change the Annuity Date by submitting a written request,
at least 30 days before the Annuity Date.

Types of Annuity Payments
- -------------------------

You may choose:
    
  .  fixed annuity payments,
  .  variable annuity payments,
  .  a combination of fixed and variable annuity payments, or
  .  systematic withdrawals.

Fixed annuity payments are monthly payments of fixed amount that we guarantee
for the dollar amount or number of years that you choose.  Variable annuity
payments are monthly payments that vary in amount, depending on the performance
of the Variable Fund Accounts you select.  We do not guarantee the amount of
variable annuity payment.     

Amount of Annuity Payments
- --------------------------

The amount of your first annuity payment, whether fixed or variable, will depend
on the amount of Contract Value you apply to a Distribution Option.  Your
Contract contains tables showing examples of the first monthly annuity payment
that you would receive for each $1,000 of Contract Value you apply to a
Distribution Option.
    
The amount of each subsequent fixed annuity payment is fixed by the terms of the
Distribution Option you choose.  To calculate the amount of your subsequent
variable annuity payments, we use a unit of measure called an "ANNUITY UNIT."
The amount of each subsequent variable annuity payment will equal the product
of:     
  .  the number of Annuity Units credited to you multiplied by
  .  the values of those Annuity Units ("ANNUITY UNIT VALUES").

Number of Annuity Units.  When you apply your Contract Value to a Distribution
Option, we credit you with a number of Annuity Units for each Variable Fund
Account that you select. To determine the number of Annuity Units to credit you,
we divide the amount of your first variable annuity payment by the Annuity Unit
Values of each Variable Fund Account on the business day we determine the
credit.   The number of Annuity Units for each Variable Fund Account will remain
constant thereafter.

Annuity Unit Values.  To determine the Annuity Unit Values of each Variable Fund
Account on a given business day, we take the previous day's Values and adjust
them to reflect:
    
  .  the performance of the corresponding Funds (including any dividends or
     capital gains distributions);
  .  any charges or credits for any income or other taxes relating to the
     Variable Fund Account operation;
  .  Separate Account charges; and
  .  an assumed annual rate of return of 3% on the Variable Fund Accounts (we
     call this the "3% ASSUMED RATE"). If the actual performance of a Variable
     Fund Account for the month is at an annual rate that exceeds the 3% assumed
     rate, your annuity payments will increase. Conversely, if the actual
     performance is at an annual rate below the 3% assumed rate, your annuity
     payment will decrease.

Distribution Options
- --------------------
    
The Contract offers 6 Distribution Options ("OPTIONS").  You may receive
payments under other options, including a lump sum, that you and we agree upon
in writing.  Also, we may, at our option, offer more favorable Distribution
Options in the future.  Once annuity payments have begun, you may not change
your Distribution Option.  However, if you are receiving variable annuity
payments under a Distribution Option that is not based on the life of the
Annuitant, you may receive a lump sum payment equal to the present value of any
future variable annuity payments remaining under that Distribution Option.

If you want to receive fixed annuity payments, you may select any one of the
Options 1 through 5.  If you want to receive variable annuity payments, you must
select Option 1, 2, or 3. Option 6 provides for systematic withdrawals out of
the Fixed Fund Account and/or Variable Fund Accounts.  A Fixed Fund Account
withdrawal charge may apply under Option 6.     

Please note that, although Distribution Options 1, 2 and 3 are designed to
provide annuity payments for life, electing these Options on a variable annuity
basis involves investment risks.  If the investment performance of the Variable
Fund Accounts you select is poor, the amount of future annuity payments could
fall substantially, possibly to zero.

<TABLE>
<S>                              <C>
- --------------------------------------------------------------------------------------------------------------------
OPTION 1
Income Payments for Life         Annuity payments for as long as the Annuitant is alive.  Please note that the
                                 Annuitant or other payee could receive only one annuity payment if the Annuitant
                                 dies before the second annuity payment.
- --------------------------------------------------------------------------------------------------------------------
OPTION 2
Income Payments for Life with    Annuity payments for a certain period of time even if the Annuitant dies before
 a Certain Period Guaranteed     that period of time has expired.
- --------------------------------------------------------------------------------------------------------------------
OPTION 3
Joint and Survivor Life Income   Annuity payments for as long as the Annuitant or the Joint Annuitant is alive.
                                 Please note that an Annuitant or other payee could receive only one annuity
                                 payment if both Annuitants die before the second annuity payment.  If one of these
                                 persons dies before the Annuity Date, the survivor becomes the sole Annuitant and
                                 may elect to receive any one or more of the other Distribution Options.
- --------------------------------------------------------------------------------------------------------------------
OPTION 4
Income for Specified Period      Equal payments for an agreed upon period of time (not longer than 30 years).  We
                                 determine the amount of each payment pursuant to an annuity payment table
                                 contained in the Contract.
- --------------------------------------------------------------------------------------------------------------------
OPTION 5
Income of Fixed Amount           A sum of money is transferred to us.  In exchange, we agree, pursuant to an
                                 annuity payment table contained in the Contract, to pay the specified amount of
                                 interest on the principal and to make periodic payments of a fixed dollar amount
                                 that is chosen for as long as the principal and interest earnings last.

OPTION 6
Systematic Withdrawals           Substantially equal monthly, quarterly, semi-annual, or annual payments made over
                                 the life expectancy of the Annuitant or a shorter period of time.  See "Special
                                 Services  Systematic Withdrawal Program" in this prospectus for details.
- --------------------------------------------------------------------------------------------------------------------
</TABLE>

No partial or full withdrawals are permitted under Options 1 through 5 after the
Annuity Date.

If you are using this Contract to fund a Qualified Plan and if you are required
to take distributions under federal income tax law, we offer a service to
determine the minimum amount of distribution that you must take each year.  You
may arrange with us to have this amount distributed by systematic withdrawal.

DEATH BENEFITS

Death Benefits Prior to the Annuity Date
- ----------------------------------------

If you are the Contract owner as well as the Annuitant and you die before the
Annuity Date, we will pay a death benefit to your Beneficiary.  If you are the
Contract owner but not the Annuitant and you die before the Annuity Date, we
will pay a death benefit to the Annuitant, or the Beneficiary if the Annuitant
does not survive you.

The death benefit is the greater of:
    
  .  the Contract Value on the date we receive proof of death; or
  .  the sum of the premium payments credited to the Contract, less the amount
     of any withdrawals and less any required premium tax.     

We will pay the death benefit in a lump sum. Instead of receiving the death
benefit in a lump sum, the Beneficiary or the Annuitant, if entitled, may choose
a Distribution Option.

If you are the Contract owner and you die before the Annuity Date, federal
income tax law requires your death benefits to be paid out as follows:
    
  .  If you are also the Annuitant and you did not designate a Beneficiary or no
     Beneficiary survived you, then full distribution to your estate must occur
     within five years after your death.
  .  If you are also the Annuitant and the Beneficiary is your spouse, or if you
     are not the Annuitant but your spouse is, then your spouse may:
     .  assume ownership as the Annuitant and defer distribution until the
        Annuity Date, or
     .  receive distributions over a period of time not exceeding your
        surviving spouse's life or life expectancy, in which case payments must
        begin within one year after your death.
  .  If you are also the Annuitant and the Beneficiary is not your spouse, then
     distribution must begin within one year after your death and must be made
     over a period of time not exceeding the life or life expectancy of the 
     Beneficiary, or, in the alternative, full distribution must occur within
     five years after your death.
  .  If you are not the Annuitant and the Annuitant is not your spouse, then
     distribution must begin within one year after your death and must be made
     over a period of time not exceeding the life or life expectancy of the
     Annuitant, or Beneficiary if the Annuitant does not survive you, or, in
     the alternative, full distribution must occur within five years after
     your death.     

Death Benefits On or After the Annuity Date
- -------------------------------------------

Under current federal income tax law, if you are the Contract owner as well as
the Annuitant and you die on or after the Annuity Date, any payment that remains
under the terms of the Contract must continue at least as rapidly as before your
death.  To the extent that the Distribution Option then in effect provides for
any benefits following the Annuitant's death, the Beneficiary may:
    
  .  continue to receive the same payments as the Annuitant; or
  .  if permitted under the Distribution Option, receive higher payments, but
     over a shorter period of time, than the Annuitant was receiving; or
  .  if permitted under the Distribution Option, take full distribution of the
     remaining value at the Annuitant's death.

HOW DO I...?     

    
 ...Buy a Contract
   --------------
     

To buy a Contract, you must complete an application and submit it, along with
your initial premium payment, to us at the address on the cover of this
prospectus. You must be of legal age and reside in a state where we are offering
the Contract. The Contract is not available to you if you have attained the age
of 85.

If a premium payment accompanies your application and it is complete, we will
either accept it and issue a Contract to you, or reject it and return the
premium payment, within two days after we receive it.  If your application is
not complete, or is incorrectly completed, we will ask you to complete it within
five days after we receive it.  If we do not receive a correctly completed
application within this five-day period, we will return your premium payment to
you immediately, unless you consent to our retaining the premium payment until
you complete the application.  We will credit your initial premium payment
within two business days after we receive the last information we need to
process your application.

The current minimum initial and additional premium payments we accept are as
follows:

* Employees of any of the USAA Group of Companies who purchase the Contract may
  make an initial premium payment of $500 for Nonqualified Annuities, and
  minimum subsequent premium payments by payroll deduction in an amount not less
  than $25 for Nonqualified Annuities, IRAs and SEP-IRAs.

    
 ...Invest More Money
   -----------------
     

As long as your Contract Value does not fall below $1,000 (other than for
Contracts issued as part of Qualified Plans), you need not make any more premium
payments.  You may, however, make subsequent premium payments at any time before
the Annuity Date.  Simply send us your subsequent premium payments at the
address on the cover of this prospectus.  We will allocate them among the
various Fixed and Variable Fund Accounts in the same way as the initial premium
payment.  The minimum amount we will accept is shown in the table above.
    
 ..Access My Money
  ---------------
     

You may withdraw some or all of your money at any time during the Accumulation
Phase.  The minimum amount that you may withdraw is $500, or, if less, the
remaining balance in the Fixed and/or Variable Fund Account from which you are
withdrawing.

To withdraw money, simply contact us at the telephone number or address on the
cover page of this prospectus. Unless you are withdrawing all of your Contract
Value, you must specify the Fixed and/or Variable Fund Accounts that you want to
withdraw from.   If you do not specify the Variable Fund Accounts, we will
withdraw money proportionately from your Contract Value in each Variable Fund
Account.

                                                                    TRANSACTIONS

There is no charge for withdrawing money from a Variable Fund Account. However,
we will deduct the  $30 Contract Maintenance Charge  if you withdraw all of your
money from the Contract.  We also may deduct a withdrawal charge from the amount
you withdraw from the Fixed Fund Account.  (See "Charges and Deductions - Fixed
Fund Account Withdrawal Charge.")  A 10% federal income tax penalty may apply if
you withdraw money before age 59  1/2.  You also will pay taxes on any earnings
that you withdraw.   For a discussion of tax aspects, see "Tax Information,"
below.  You should seek the advice of a tax adviser before withdrawing 
money.

 ...Change My Investment Choices
   ----------------------------

During the Accumulation Phase, you may change your investment choices by
transferring money among the Fixed and Variable Fund Accounts.  There is no
charge to transfer money from a Variable Fund Account, but money that you
transfer from the Fixed Fund Account may be subject to a withdrawal charge. (See
"Charges and Deductions - Fixed Fund Account Withdrawal Charge.")  The following
restrictions apply during the Accumulation Phase:     
  1.   You may make six transfers each Contract Year.
  2.   The minimum amount of value that you may transfer from one Account to
       another is $100, or, if less, your total remaining Account balance.
  3.   Your written or telephone request for a transfer must clearly state the
       amount to be transferred, the Fixed or Variable Fund Account from which
       it is to be withdrawn, and the Account to which it is to be credited.

During the Distribution Phase, the Annuitant or other payee may transfer Annuity
Units among the Variable Fund Accounts (up to a maximum of four Variable Fund
Accounts), or from a Variable Fund Account to a Fixed Annuity under the same
Distribution Option previously in effect.  There is no charge for such
transfers.  Transfers made during the Distribution Phase are subject to
restriction 3 noted above, as well as the following restrictions:
   1.   You may make up to 3 transfers per Contract Year from a Variable Fund
        Account to another Variable Fund Account or to a Fixed Annuity.
   2.   You may not transfer from a Fixed Annuity to a Variable Annuity or to a
        new Distribution Option.
   3.   The minimum amount that you may transfer from a Variable Fund Account is
        $100.
   4.   Once you have transferred Annuity Unit Value to the Fixed Fund Account,
        it is locked in and cannot be transferred out.

We can terminate, suspend, or modify these transfer privileges without prior
notice.
    
 ...Change My Premium Allocations
   -----------------------------
     

You may change the allocation of your subsequent premium payments at any time by
calling or writing to us at the number or address on the cover page of this
prospectus.   A request to change subsequent premium payment allocations will be

we receive the request.

address on the cover of this prospectus at least 30 days before the Annuity

You may transfer or assign ownership of the Contract, subject to legal
restrictions.  To transfer or assign ownership, you must notify us in writing at

We will ask you for your:

     other electronic transmission device as telephone requests, so please be
     sure to provide the same identifying information on those requests as well.
     

We will use reasonable procedures to confirm that instructions given by
telephone are genuine, and only if we do not, will we be liable for any losses
because of unauthorized or fraudulent instructions.  In addition to asking you
for identifying information, we record all telephone communications that concern
purchases, redemptions or transfers.  We also send confirmations of all
transactions to the Contract owner's address.  We may modify, suspend or
discontinue this telephone transaction privilege at any time without prior
notice.
    
 ...Cancel My Contract
   ------------------
     

You may return your Contract to us within the Free Look Period. If you return
your Contract within the Free Look Period, we will give you a refund.  We will
refund any premium payment allocated to the Fixed Fund Account, plus the greater
of:
  .  premium payments allocated to the Variable Fund Accounts, or
  .  the value of the Variable Fund Accounts as of the day we receive your
     cancellation request plus any mortality and expense risk charge,
     administrative expense charge and any premium taxes that we have deducted.

We will void the Contract and treat it as if we had not issued it.

                                                                    TRANSACTIONS

 ...Keep Track of My Investments
   ----------------------------

At least once each Contract Year, we will send you a statement of information
about your Contract.  The statement will show the number of Accumulation Units
we recently credited to your Contract for each Variable Fund Account and the
dollar value of the Accumulation Units.  We may send you a statement more
frequently.  We also will send you semiannual reports for the Funds that
correspond to the Variable Fund Accounts, periodic reports for the Separate
Account, and any other information that the law requires us to send to you.

You now have access to information about your Contract 24-hours a day, 7 days a
week through USAA's TouchLineSM.

TouchLine provides a fast, convenient way to find out:
  .  your total Contract Value,
  .  a listing of Variable Fund Accounts and current Accumulation Unit Values,
     and
  .  the date and amount of your last premium payment or withdrawal.

You may access TouchLine by using your touch-tone phone and dialing 1-800-531-
5433.  You will need your USAA number or Social Security number and your USAA
PIN (personal identification number).

You may also visit us online at www.usaa.com.

 ...Start Receiving Annuity Payments
   --------------------------------
     

To receive annuity payments, you must notify us in writing at least 30 days
before the Annuity Date of:
  .  the Distribution Option you want to use to begin annuity payments;
  .  the type of annuity payments you want (fixed, variable, a combination of
     fixed and variable annuity payments, or systematic withdrawals); and
  .  if you want to receive variable annuity payments, the Variable Fund 
     Accounts (up to 4) you want to use to fund your payments.

Once we have the necessary information, we will apply your Contract Value, less
any required premium tax, to the Distribution Option that you have selected.

If you have not chosen a Distribution Option at least 30 days before the Annuity
Date, we will apply your Contract Value, less any required premium tax, to
Distribution Option 2, with monthly payments guaranteed for 10 years.  In
addition, we will apply any Fixed Fund Account Value to provide you with fixed
annuity payments. Similarly, we will apply any Variable Fund Account Value to
provide variable annuity payments funded from the same Variable Fund Accounts to
which you have allocated your Contract Value as of the Annuity Date and in the
same proportions.   We will apply your Contract Value as of the end of the
business day immediately preceding the tenth day before the Annuity Date.

If you have assigned your Contract, the amount due the assignee must be paid in
a lump sum before we can determine or begin any annuity payments.

If at the time you want to begin annuity payments, your Contract Value is less
than $2,000 or would provide a monthly distribution payment of less than $20 per
month, we may cancel your Contract.  In that event, we will pay the Annuitant
the Contract Value in a lump sum and be released of any further obligations.

PROCESSING DATES

Generally, we will process the following transactions using the Fixed and
Variable Fund Account Values (including Accumulation and Annuity Unit Values)
computed on the business day that we receive your payment, request, notice,
and/or other documents or information necessary to complete your transaction:
  .  premium payments;
  .  transfers of money or Annuity Units among investment choices  (including
     transfers in the dollar cost averaging program);
  .  withdrawals of money (including withdrawals in the systematic withdrawal
     program); and
  .  death benefit claims.

If we receive your payment, request, etc. BEFORE 3 P.M. Central time on a
business day, we will process your transaction using that day's Fixed and
Variable Fund Account Values.  If you miss the 3 p.m. deadline that day, we will
process your transaction using the next business day's Fixed and Variable Fund
Account Values.

In this prospectus, we use the term "business day" to mean any day Monday
through Friday when the New York Stock Exchange is open for regular trading.
The Exchange usually closes at 4 p.m. New York time (3-p.m. Central time) and is
not open on federal holidays.  Business day does not include:
    
  .  any day when the funds do not compute the value of their shares; or
  .  any day when we do not receive an order to purchase, withdraw, or transfer
     Accumulation Units or purchase or transfer Annuity Units.     

Please keep in mind that we cannot process your telephone or written requests if
you do not provide all of the information we need to complete the transaction.
If the transaction requires you to notify us in writing, you must sign your
written request.

                                                                    TRANSACTIONS

Special Processing
- ------------------

Initial Premium Payments
  .  If your initial premium payment accompanies a completed application, we
     will credit your payment within two business days after we receive the
     payment and completed application.
  .  If your initial premium payment accompanies an incomplete application, we
     will credit your initial premium payment within two business days after we
     receive the last information we need to process your application.
  .  If you allocate any part of your initial premium payment to the Fixed Fund
     Account, we will credit it to that Account on the Effective Date.
  .  If you allocate any part of your initial premium payment to any of the
     Variable Fund Accounts, we will credit it to the USAA Life Money Market
     Fund Account on the Effective Date. Your premium will remain in the USAA
     Life Money Market Fund Account for the Free Look Period plus five calendar
     days. On the business day immediately after the end of that period, we will
     allocate your initial premium payment, together with any subsequent premium
     payments that you have made, plus any earnings, to the Variable Fund
     Accounts as you directed on the application.

Initial annuity payments
To calculate the amount of the initial annuity payment, we use the Contract
Value and Annuity Unit Values of the business day preceding the 10th day before
the Annuity Date.

POSTPONEMENT OF PAYMENTS

We will normally pay amounts withdrawn from a Contract within 7 days after we
receive your written or telephone request.  In addition, we will normally
process your transactions using the Fixed or Variable Fund Account Values as of
the business day we receive your request.

However, we may not be able to determine the value of the assets of the Variable
Fund Accounts if:
  .  the New York Stock Exchange is closed for other than customary weekends
     and holidays;
  .  trading on the New York Stock Exchange is restricted; or
  .  an emergency exists and it is not reasonably practicable to dispose of
     securities held in the Separate Account or determine their value.

In such cases, we may postpone the payment of withdrawal proceeds or defer
acting upon a transfer request or any other transaction pertaining to the
Separate Account.  We also may postpone payments or defer such other
transactions where the SEC permits us to do so for the protection of  Contract
owners.  In addition, we will defer requests for withdrawals that would be
derived from a premium payment made to us by a check that has not cleared the
banking system, to the extent permitted by law at the time, until payment of the
check has been honored.

We can defer the payment of a withdrawal from the Fixed Fund Account for up to
six months from the business day we receive your written or telephone request.

MORE INFORMATION ABOUT...

 ...USAA Life
   ---------

USAA Life is a Texas insurance company organized in 1963.  We are principally
engaged in writing life insurance policies, annuity contracts and health
insurance policies.   We are  authorized to transact insurance business in all
states including the District of Columbia but excluding New York.  On a
consolidated basis prepared in accordance with Generally Accepted Accounting
Principles ("GAAP"), we had total assets of $8,500,568,000 on December 31, 1998.
We are a wholly owned subsidiary of USAA, the parent company of the USAA group
of companies.  USAA is a diversified financial services concern providing
members and their families with a wide array of products and services to
maintain and enhance their financial lifestyle.   Our Home Office is 9800
Fredericksburg Road, San Antonio, Texas 78288.     

As of the date of this Prospectus, both we and USAA held the highest ratings
from A.M. Best Company (A++ Superior) and Standard & Poor's Corporation (AAA
Superior).  Both we and USAA also held the second-highest and highest ratings
(AA1 Excellent and Aaa Exceptional), respectively, from Moody's Investors
Service.  The ratings published by these independent financial rating agencies
serve as measurements of an insurer's financial condition.  The ratings are
based on an evaluation of many factors, including:
    
  .  profitability
  .  asset quality
  .  adequacy of reserves
  .  capitalization
  .  management practices.
     
These ratings are not a rating of investment performance that our customers have
experienced or are likely to experience in the future.
    
 ...The Separate Account
   --------------------
     

We own the assets of the Separate Account.  The Separate Account is a segregated
asset account under Texas law.  That means we account for the Separate Account's
income, gains, and losses separately from the results of our other operations.
It also means that only the assets of the Separate Account that are in excess of
the reserves and other Contract liabilities with respect to the Separate Account
are subject to liabilities relating to our other operations.  The Separate
Account consists of 12 Variable Fund Accounts, each of which invests in a
corresponding Fund.
    
 ...The Funds
   ---------
     

Substitution of Funds
If the shares of any Fund should no longer be available for investment by the
Separate Account, or if in our judgment further investment in such shares would
be undesirable in view of the purposes of the Contracts, we may eliminate that
Fund and substitute shares of another eligible investment fund.  In most cases,
a substitution of shares of any Fund would require prior approval of the SEC.
We also may add new Variable Fund Accounts that invest in additional mutual
funds.

Dividends and Capital Gain Distributions
We have elected to automatically reinvest any dividends or capital gain
distributions paid on a Fund's shares in additional shares of the Fund at the
net asset value of the Fund's shares on the date payable.  Dividends and
distributions lower the net asset value of each share of the corresponding Fund,
other than the Money Market Fund, but also increase the number of outstanding
shares of the Fund.  The value of your interest in the corresponding Variable
Fund Account does not change as a result of any dividends or distributions.

                                                               OTHER INFORMATION

Voting Privileges
Based on our present view of the law, we will vote the shares of the Funds that
we hold directly or indirectly through the Separate Account in accordance with
instructions that we receive from Contract owners entitled to give such
instructions.  The persons entitled to give voting instructions and the number
of shares that a person has a right to instruct will be determined based on
Variable Fund Account Values as of the record date of the meeting.

We will vote shares attributable to Contracts for which we have not received
instructions, as well as shares attributable to us, in the same proportion as we
vote shares for which we have  received instructions, unless we determine that
we may vote such shares in our own discretion.  None of the Funds hold regular
shareholder meetings.

Special Considerations
The Funds managed by Scudder, Alger Management, and Bankers Trust offer shares
to separate accounts of unaffiliated life insurance companies to fund benefits
under variable annuity contracts and variable life insurance policies.  The
Funds managed by USAA IMCO offer shares only to our separate accounts to fund
benefits under the Contracts and the variable life insurance policies that we
offer. The boards of directors or trustees of these Funds monitor for possible
conflicts among separate accounts buying shares of the Funds.  Conflicts could
develop for a variety of reasons.  For example, differences in treatment under
tax and other laws or the failure by a separate account to comply with such laws
could cause a conflict.

To eliminate a conflict, a Fund's board of directors or trustees may require a
separate account to withdraw its participation in a Fund. A Fund's net asset
value could decrease if it had to sell investment securities to pay redemption
proceeds to a separate account withdrawing because of a conflict.
    
 ...The Contract
   ------------
     

Our obligations arising under the Contracts are general corporate obligations.
We have the responsibility for administration of the Contracts.  Among other
things, this responsibility includes application and premium processing, issuing
the Contracts, and maintaining the required Contract owner's records.

Our affiliate, USAA IMCO, is the  principal underwriter of the Contracts. USAA
IMCO has agreed to offer the Contracts for sale and distribution through certain
of its registered representatives who are also qualified life insurance agents
employed by USAA Life.  USAA IMCO also will provide certain administrative
services to USAA Life.

Contract Agreement
The Contract and the application form the entire agreement between you and USAA
Life.  We will consider statements in the application to be representations and
not warranties.  Only an officer of the Company has authority to:
    
  .  waive a provision of the Contract, or
  .  agree with you to changes in the Contract, and then only in writing.     

We reserve the right to change the Contract to comply with all federal and state
laws that apply to variable annuity contracts. Among other things, we may
conform the terms of the Contract to reflect any changes in the federal tax laws
so that the Contract will continue to qualify as an annuity contract.

Contract Owner
The rights and privileges of the Contract belong to the Contract owner during
the Annuitant's lifetime.  The Contract owner is the Annuitant unless the
application designates a different Contract owner, and we have approved. If the
Contract owner and the Annuitant are different persons and the owner dies either
before or after the Annuity Date, then the rights and privileges of ownership
will vest in the Annuitant, or the Beneficiary if the Annuitant does not survive
the owner.  If the Annuitant is the Contract owner and dies, then the rights and
privileges of ownership will vest in the Beneficiary.

Annuitant
The Annuitant must be a natural person.  The maximum age of the Annuitant on the
Annuity Date is age 95.  If an Annuitant who is not the Contract owner dies
before the owner prior to the Annuity Date, then the Beneficiary becomes the
Annuitant, unless the Contract owner designates another Annuitant by written
request.  An Annuitant who is not the Contract owner has no rights or privileges
prior to the Annuity Date.  When a Distribution Option involving life
contingencies is elected, the amount payable as of the Annuity Date is based on
the age and sex (where permissible) of the Annuitant, as well as the
Distribution Option chosen and the Contract Value.

Beneficiary
The Beneficiary is the person or persons named in the application who may be
entitled to receive any Contract benefits that we provide upon the Contract
owner's or Annuitant's death.  A contingent beneficiary may be named to receive
the Contract benefits in the event the Beneficiary does not survive the
Annuitant.  If the Beneficiary dies while receiving annuity payments, we will
pay any remaining payments due to the Beneficiary's estate.

Unless otherwise provided, we will pay benefits as follows:
    
  .  If two or more Beneficiaries have been named, we will pay all benefits in
     equal shares to those living at the time of the Annuitant's death; and
  .  If no Beneficiary survives the Annuitant, we will pay benefits to the
     Annuitant's estate.

 ...Charges and Deductions
   ----------------------
     

As a Contract owner, you will bear, directly or indirectly, the charges and
expenses described below.

Premium taxes
We will deduct any premium taxes or other similar assessments that states,
municipalities or other governmental entities may impose.  Premium taxes
currently imposed range from 0% to 3.5%.  We will deduct these charges from your
Contract Value either when we receive the premium payment or when annuity
payments start, as required by state law.  The amount of any premium tax charge
will depend on your state of residence.  You may not deduct any premium tax
charge on your federal income tax return.

Contract Maintenance Charge
We will deduct a $30 Contract Maintenance Charge from your Contract Value on
each Contract anniversary.  If you surrender your Contract, we will deduct the
entire Contract Maintenance Charge for that year.  We will deduct the charge
proportionately from your investment in the Fixed and Variable Fund Accounts.

We will not deduct this charge:
  .  once you have elected to receive annuity payments under the Contract,
  .  from death benefits paid on the death of a Contract owner or Annuitant,
  .  from a lump sum payment in lieu of annuitization, or
  .  upon termination due to insufficient Contract Value.

We also will waive the charge for Contracts issued under the Texas Optional
Retirement Program.

Administrative Expense Charge
We assess each Variable Fund Account a daily charge at an annualized rate of
0.10% of the average daily net assets of each Variable Fund Account.

This charge, along with the Contract Maintenance Charge, reimburses us for the
expenses we incur in the issuance and maintenance of the Contracts and each
Variable Fund Account.  These expenses include, but are not limited to:
    
  .  preparation of the Contracts, confirmations, periodic reports and
     statements
  .  maintenance of the Contract owner's records
  .  maintenance of the Separate Account records
  .  administrative personnel costs, mailing costs, data processing costs, legal
     fees, accounting fees, filing fees, the costs of other services necessary
     for Contract owner servicing
  .  all accounting, valuation, regulatory and reporting requirements.
     

We do not intend to profit from this charge.   We will reduce it to the extent
it is in excess of what is necessary to reimburse us for administrative
expenses.  Should this charge prove to be insufficient, we will not increase
this charge (or the Contract Maintenance Charge) and we will bear the loss.

Alger Management and Bankers Trust, or their affiliates, reimburse us for the
cost of administrative services that we provide to the Funds they manage as
investment choices under the Contracts.  Compensation is paid out of fee
earnings, based on a percentage of each of these Fund's average net assets
attributable to a Contract.

Mortality and Expense Risk Charge
To compensate us for assuming mortality and expense risks, we assess each
Variable Fund Account a daily charge at the annualized rate of 0.65% of the
average daily net assets of each Variable Fund Account attributable to the
Contracts.  This charge consists of approximately 0.40% for mortality risks and
0.25% for expense risks.  We assume mortality risks:
    
  .  by our contractual obligation to make annuity payments after the Annuity
     Date for the life of the Annuitant based on annuity rates guaranteed in the
     Contracts under Distribution Options that involve life contingencies; and
  .  by our contractual obligation to pay a death benefit upon the death of an
     Annuitant or Contract owner prior to the Distribution Phase.     

The expense risk we assume is that all actual expenses involved in administering
the Contracts, including Contract maintenance costs, administrative costs,
mailing costs, data processing costs, legal fees, accounting fees, filing fees
and the costs of other services may exceed the amount recovered from the
Contract Maintenance Charge and the Administrative Expense Charge.

We guarantee the Mortality and Expense Risk Charge.  We cannot increase it.  If
the Mortality and Expense Risk Charge is insufficient to cover the actual costs
associated with the Contracts, we will bear the loss.  Conversely, if the amount
deducted proves more than sufficient, the excess will be our  profit.  We expect
to profit from this charge.

Income Taxes
We reserve the right to charge for federal income taxes that may be incurred by
the Separate Account.  This charge applies only to the Variable Fund Accounts
under this Contract.

Expenses of the Funds
Expenses paid out of the assets of the Funds are described in detail in the
accompanying prospectuses for the Funds.

Transfer Fee
We do not charge a fee for transfers among the Variable Fund Accounts, or for
transfers from a Variable Fund Account to the Fixed Fund Account.  Transfers
from the Fixed Account to a Variable Fund Account may be subject to a withdrawal
charge.  (See "Fixed Fund Account Withdrawal Charge," below.)

Fixed Fund Account Withdrawal Charge
We will deduct a charge from some premium payments or other payments withdrawn
or transferred from the Fixed Fund Account.  In setting interest rates for the
Fixed Fund Account, we take numerous factors into account, including the length
of time that we expect Owners to leave funds in the Fixed Fund Account.
Generally speaking, a high degree of Contract owner "persistence" in the Fixed
Fund Account tends to enable us to declare higher rates of interest than we
otherwise could.  The Fixed Fund Account Withdrawal Charge is intended to
promote such persistence and to compensate us for costs we may incur if
persistence is less than we estimate.

The Fixed Fund Account Withdrawal Charge is a percentage of the net amount of
any premium payment or transfer into the Fixed Fund Account (collectively,
"PAYMENTS") that is subsequently withdrawn or transferred.  The  percentage will
depend on how many years have passed since the Payment being withdrawn or
transferred was credited to the Fixed Fund Account, according to the following
schedule:

The Fixed Fund Account Withdrawal Charge does not apply to the Variable Fund
Accounts.

In determining the charge, we consider a year to be a period of 365 days unless
a leap year is involved.  In addition, we treat Payments that you withdraw or
transfer on a first-in first-out ("FIFO") basis.  This means the earliest
Payments will be considered withdrawn first and before any earnings are deemed
to be withdrawn. We calculate the  Fixed Fund Account Withdrawal Charge
separately for each Payment  into the Fixed Fund Account. We will calculate the
Fixed Fund Account Withdrawal Charge in accordance with applicable state law.
Please refer to your Contract for more information.

The Fixed Fund Account Withdrawal Charge will not apply:
  .  to payments of death benefits prior to the Annuity Date.
  .  to payments of a lump sum in lieu of a Distribution Option.
  .  upon termination of a Contract due to insufficient Contract Value.
  .  upon commencement of a Distribution Option.
  .  to any Payment received at least seven years prior to the requested date of
     withdrawal or transfer and that has not been previously withdrawn or
     transferred.
  .  to the amount of any interest earned on the amount of your Payments into
     the Fixed Fund Account.
  .  to withdrawals or transfers during any Contract Year of up to 15% of the
     value of the Payments that have been made to the Fixed Fund Account during
     the seven years preceding the requested date of a withdrawal or transfer
     ("15% FREE WITHDRAWAL AMOUNT"). Unused portions of this 15% Free Withdrawal
     Amount are not carried forward to future Contract Years.

 ...Year 2000
   -------

Like other organizations around the world, USAA Life could be adversely affected
by the so-called "Year 2000 problem."  The problem exists because many computer
programs use only the last two digits to refer to a year and may not properly
recognize a year that begins with a "20" instead of a "19."  As a result, such
programs might not properly process and calculate information that relates to
dates beginning January 1, 2000 and beyond.
    
USAA Life has spent much effort and expense to confront the Year 2000 problem
and we expect to have our computer systems ready for the year 2000 by mid-1999.
In addition, we are assessing the Year 2000 readiness of the Funds in which the
Separate Account invests.  Although we cannot say that you will experience no
effect from this situation, we can tell you that we are making a large effort to
avoid any ill effects upon our Contract owners.     

TAX INFORMATION

We base this discussion of taxes on current federal income tax law and
interpretations. Congress has in the past changed and may again in the future
change the tax treatment of annuities. The Treasury Department may issue new or
amended regulations or other interpretations of that law. The courts may also
interpret the law. These changes could affect you retroactively. The following
is for general information purposes only. You should consult a qualified tax
advisor for tax advice about the Contracts.

THIS DISCUSSION DOES NOT ADDRESS STATE OR LOCAL TAX, ESTATE AND GIFT TAX, OR
SOCIAL SECURITY TAX CONSEQUENCES OF THE CONTRACTS.

Nonqualified Plan Contracts
- ---------------------------

THE FOLLOWING DISCUSSION APPLIES TO CONTRACTS UNDER NONQUALIFIED PLANS.

Increases in Value
General Rule.  Generally, Section 72 of the Internal Revenue Code of 1986
("CODE") governs the federal income taxation of annuities. If you are a natural
person, you will not be taxed currently on increases in your Contract's Fixed
Fund Account Value or Variable Fund Account Value.

Owners Other Than Natural Persons.  If you are not a natural person, such as a
corporation, the Code taxes you currently on increases in a contract's Fixed
Fund Account Value or Variable Fund Account Value. The Code also contains
exceptions to this rule.

Diversification.  The Code and underlying Treasury Regulations set forth
requirements for investment diversification that each Variable Fund Account must
meet. Generally, a Variable Fund Account will satisfy these requirements if its
corresponding Fund satisfies them. A Fund's failure to meet the diversification
requirements will subject the Contract owner that invests in a Variable Fund
Account corresponding to that Fund to current taxation on any increases in the
Contract's Fixed Fund Account Value and Variable Fund Account Value for the
period of such diversification failure, and any subsequent period.

Contract Owner Control. The Treasury Department has stated that it may issue
guidelines that limit a Contract owner's control of investments underlying a
variable annuity. If a Contract failed to meet those guidelines, you would be
taxed on the Contract's current income. The Treasury Department has said
informally that those guidelines may limit the number of investment funds and
the frequency of transfers among those funds. The issuance of such guidelines
may require us to limit your right to control the investment. The guidelines may
apply only prospectively, although they could apply retroactively if they do not
reflect a new Treasury Department position.

Withdrawals During the Accumulation Phase
During the Accumulation Phase, you will be taxed on partial and full withdrawals
from a Nonqualified Plan Contract to the extent of any income in the Contract.
Income in the Contract equals income earned on previous premium payments. The
amount of any partial or full withdrawal exceeding income in the Contract is not
taxable. We combine all Contracts we have issued to you in the same calendar
year in determining the amount of any withdrawal that is includible in your
income for tax purposes.

Assignments
An assignment of a Nonqualified Plan Contract will receive the same tax
treatment as a partial withdrawal, discussed immediately above.

Distributions During the Distribution Phase
During the Distribution Phase, each annuity payment from a Nonqualified Plan
Contract is taxable in part and nontaxable in part. You calculate the nontaxable
part first.

For fixed annuity payments, the nontaxable part of each payment is the product
of (1) the amount of the payment times (2) the ratio of (a) the investment in
the Contract to (b) the total value of expected payments. Investment in the
Contract is the total of all your premium payments less any previous
distributions that were not included in your income.

For variable annuity payments, the nontaxable part of each payment is (1) the
investment in the contract divided by (2) the total number of expected payments.

The taxable part of each payment is the balance left after you subtract the
nontaxable part. The taxable part is taxed at ordinary income tax rates.

Penalty on Distributions
Distributions prior to age 59 1/2 during either the Accumulation or Distribution
Phase are subject to a penalty tax equal to 10% of the amount includible in
income. The penalty tax will not apply to certain distributions, including
those:
    
  .  made on or after the recipient reaches age 59 1/2.
  .  made after the death of the Contract owner, or, where the owner is not a
     natural person, the death of the Annuitant.
  .  made on account of the recipient's disability.
  .  that are part of a series of substantially equal periodic payments made at
     least annually for the life (or life expectancy) of the recipient's
     Beneficiary (under current Internal Revenue Service interpretation,
     distributions under a systematic withdrawal program will not qualify for
     this exception).
  .  made under an immediate annuity, which the Code defines in Section
     72(u)(4).
     
There is a similar penalty, also subject to exceptions, on certain distributions
from Contracts from Qualified Plans.

Death Benefits
Special rules apply to the distribution of death benefits under the Contract
either during the Accumulation Phase or during the Distribution Phase. (See
"Death Benefits.")

Tax-free Exchanges
The Code allows a tax-free exchange of one annuity Contract for another annuity
if the annuitant and the owner are the same under each Contract. This rule also
applies to variable annuity Contracts.

Transfers
The Code does not currently tax transfers between investment options.

Qualified Plan Contracts
- ------------------------

THE FOLLOWING DISCUSSION APPLIES TO CONTRACTS UNDER QUALIFIED PLANS.

You may use the Contracts with several types of Qualified Plans. The tax rules
applicable to Owners, Annuitants, and other benefit recipients vary according to
the type of Qualified Plan and the terms and conditions of the Qualified Plan.
These terms and conditions may limit the rights otherwise available to you under
the Contracts.

Accumulation Phase
In general, purchase payments made under a Qualified Plan on your behalf are
excludable from your gross income during the Accumulation Phase. The portion, if
any, of any purchase payment excluded from your gross income during the
Accumulation Phase constitutes your "investment in the contract."

Distribution Phase
When payments during the Distribution Phase begin, you will begin to receive
back your "investment in the contract," if any, as a tax-free return of capital.
The Code's rules for which portion of each payment is taxable and which is
nontaxable may vary depending on the type of Qualified Plan.

Types of Qualified Plans
The Contracts are available with the following types of Qualified Plans:
  .  Individual Retirement Annuity ("IRA")
  .  Roth IRA
  .  Simplified Employee PensionIndividual Retirement Annuity ("SEP-IRA")
  .  Salary Reduction Simplified Employee Pension-Individual Retirement
     Annuity ("SARSEP-IRA"). Beginning in 1997, employers may no longer
     establish a new SARSEP-IRA, but may maintain an existing SARSEP-IRA
  .  Simple Retirement Accounts
  .  Tax-Sheltered Annuity ("TSA").  Distributions of amounts contributed to a
     TSA Contract are restricted. The restrictions apply to amounts accumulated
     after December 31, 1988, including voluntary contributions after that date
     and earnings on prior and current voluntary contributions. These
     restrictions require that no distributions will be permitted prior to one
     of the following events: (1) attainment of age 59 1/2, (2) separation from
     service, (3) death, (4) disability, or (5) hardship (hardship distributions
     will be limited to the amount of salary reduction contributions exclusive
     of earnings)
  .  the Texas Optional Retirement Program ("ORP")
    
  .  State and Local Government and Tax-Exempt Organization Deferred
     Compensation Plans ("457 Plans"). Under 457 Plans, employees may defer a
     portion of their compensation without paying taxes until distributed.
     Distributions are restricted until: (1) age 70 1/2, (2) termination of
     employment, or (3) an unforeseen emergency. The deferred compensation and
     related earnings are the property of the employer, subject only to the
     claims of the employer's general creditors (including the employees) until
     distributed.     

Federal Income Tax Withholding
- ------------------------------

Amounts distributed from a Contract are subject to federal income tax
withholding, to the extent includible in a recipient's taxable income. A
recipient may choose not to have taxes withheld or to have taxes withheld at a
different rate by filing a withholding exemption form with us.

PERFORMANCE INFORMATION


Yield and Total Return
- ----------------------

We may advertise the yields and total returns of its Variable Fund Accounts.
These figures will be based on historical results and are not intended to
indicate future performance.  The "yield" of a Variable Fund Account refers to
the income generated by an investment in the Variable Fund Account over the
period specified in the advertisement, excluding realized and unrealized
capital gains and losses in the corresponding Fund's investments.  This income
is then "annualized" and shown as a percentage of the investment.  We also may
advertise the "effective yield" of the Money Market Variable Fund Account, which
is calculated similarly but, when annualized, the income earned by an investment
in the Money Market Variable Fund Account is assumed to be reinvested.  The
"effective yield" will be slightly higher than the "yield" because of the
compounding effect of this assumed reinvestment.

The "total return" of a Variable Fund Account is the total change in value of an
investment in the Variable Fund Account over a  period of time specified in the
advertisement.  "Average annual total return" is the rate of return that would
produce that change in value over the  specified period, if compounded annually.
"Cumulative total return" is the total return over the entire specified period,
expressed as a percentage.

Neither yield nor total return figures reflect deductions for premium taxes,
since most states do not impose such taxes.

Performance Comparisons
- -----------------------
    
We may compare a Variable Fund Account's performance to that of other variable
annuity separate accounts or investment products, as well as to generally
accepted indices or analyses, such as those provided by research firms and
rating services.  In addition, we may use performance ratings that may be
reported periodically in financial publications, such as Money Magazine, Forbes,
Business Week, Fortune, Financial Planning,  and The Wall Street Journal.

Performance information for any Variable Fund Account reflects the performance
of a hypothetical Contract and are not illustrative of how actual investment
performance would affect the benefits under your Contract.  Therefore, you
should not consider such performance information to be an estimate or guarantee
of future performance.  For more information, see the Statement of Additional
Information.

Effect of Tax-Deferred Accumulations
- ------------------------------------

Unlike taxable investments, variable annuities, such as the Contract, enable you
to defer paying federal income taxes on any earnings on your premium payments
until you withdraw them.  In addition, if you are using variable annuities, such
as the Contract, with a Qualified Plan, you can defer paying federal income
taxes on your premium payments until you withdraw them.  The chart below shows
how investing on a tax-deferred basis can increase the accumulation power of
savings over time.  The more taxes saved and reinvested, the more money you are
able to accumulate over the years.  The "Variable Annuity Surrender Value" shown
represents the lump-sum net withdrawal after payment of federal income tax.

Assuming a 28% federal tax bracket and an annual fixed yield (before the
deduction of any fees or charges) of 10% under a Qualified Plan in which tax
savings are reinvested has an equivalent annual fixed yield of 13.9% under a
conventional savings program.  This example helps demonstrate the advantage of
tax-deferred savings.  The 10% yield on the Qualified  Plan would be reduced by
the assumed impact of income tax upon withdrawal.  The amount of this reduction
in yield will vary depending upon when withdrawals are made.  The first chart
below shows the actual after-tax amounts that would be received upon full
withdrawal at the end of the periods shown.

As discussed above, contributions to Qualified Plans are not subject to federal
income tax unless and until withdrawn.  Accumulations under Qualified Plans are
generally not required to be withdrawn until age 70 1/2.  There may be
restrictions on withdrawals of certain types of  contributions until age 59 1/2,
separation from service, death, disability or  hardship.  Withdrawals before age
59 1/2 generally are subject to a 10% penalty tax in addition to regular income
tax, but withdrawals may be eligible for total or partial rollover to an IRA or
another retirement program.

The first chart below compares the potential difference in savings between a (1)
taxable investment and (2) a Contract purchased with pre-tax dollars under a
Qualified Plan. These examples assume that no money was allocated to the Fixed
Fund Account, and, therefore, do not reflect any Fixed Fund Account withdrawal
charges that might apply.

This hypothetical chart compares the results of investing an initial pre-tax 
premium of $2,000 and additional pre-tax contributions of $2,000 each year 
thereafter during the Accumulation Phase. It also assumes 28% tax rate and a 10%
rate of return and reflects the deduction of all fees and charges under 
Qualified Plan Contracts. However, because premium payments to a taxable 
investment are first taxed at a rate of 28%, each $2,000 premium payment is 
reduced to $1,440. An additional 10% tax penalty may apply to withdrawals before
age 59 1/2. If different tax rates apply to each investment, comparative values

The second chart below compares the potential difference in savings between (1)
a taxable investment and (2) a Nonqualified Contract purchased with after-tax
dollars.  Variable Annuity values shown in both tables reflect the deduction of
all Contract charges (mortality and expense risk, administrative expense and
annual maintenance).  The taxable investment values do not reflect the deduction
of any charges, which, if applied, would lower the values shown.  These examples
assume that no money was allocated to the Fixed Fund Account, and, therefore, do
not reflect any Fixed Fund Account withdrawal charges that might apply.

This hypothetical chart compares the results of investing an initial after-tax 
premium of $5,000 and additional after-tax contributions of $400 made at the 
start of each month during the Accumulation Phase. It also assumes a 28% tax 
rate and a 10% rate of return and reflects the deduction of all fees and charges
under Nonqualified Plan Contracts. An additional 10% tax penalty may apply to 
withdrawals before age 59 1/2. If different tax rates apply to each investment 
comparative values will differ.

                              GENERAL INFORMATION
                                        
  USAA Life is a stock insurance company incorporated in Texas in 1963.  USAA
Life is principally engaged in writing life insurance policies, fixed annuity
contracts and health insurance policies.  USAA Life is authorized to transact
insurance business in the District of Columbia and all states, except New York.
USAA Life is a wholly-owned stock subsidiary of the United Services Automobile
Association ("USAA"), the parent company of the USAA group of companies (a large
diversified financial services organization).


                                  DISTRIBUTOR
                                        
  The Contracts are primarily sold in a continuous offering by direct response
through salaried sales account representatives employed by USAA Life.  These
individuals are appropriately licensed at the state level to sell variable
annuity contracts and are registered with the National Association of Securities
Dealers, Inc. (the "NASD") as registered representatives or principals with USAA
Investment Management Company ("USAA IMCO").  USAA IMCO, an affiliate of USAA
Life, is registered as a broker-dealer with the SEC and the NASD.


               SAFEKEEPING OF THE ASSETS OF THE SEPARATE ACCOUNT
                                        
  All assets of the Separate Account are held in the custody and safekeeping of
USAA Life.  The assets are kept physically segregated and held separate and
apart from the assets of USAA Life's General Account.  USAA Life maintains
records of all purchases and redemptions of shares of the Funds by each of the
Variable  Fund Accounts.


                            REGULATION AND RESERVES
                                        
  USAA Life is subject to regulation by the Texas Department of Insurance and by
insurance departments of other states and jurisdictions in which it is licensed
to do business.  This regulation covers a variety of areas, including benefit
reserve requirements, adequacy of insurance company capital and surplus, various
operational standards, and accounting and financial reporting procedures.  USAA
Life's operations and accounts are subject to periodic examination by insurance
regulatory authorities.  The Contracts described in the prospectus are filed
with and (where required) approved by insurance officials in each state and
jurisdiction in which Contracts are sold.

  Although the federal government generally has not directly regulated the
business of insurance, federal initiatives often have an impact on the insurance
business in a variety of ways.  Federal measures that may adversely affect the
insurance business include employee benefit regulation, tax law changes
affecting the taxation of insurance companies or of insurance products, changes
in the relative desirability of various personal investment vehicles, and
removal of impediments on the entry of banking institutions into the insurance
business.  Also, both the executive and legislative branches of the federal
government periodically have under consideration various insurance regulatory
matters, that could ultimately result in direct federal regulation of some
aspects of the insurance business.  It is not possible to predict whether this
will occur or, if so, what the effect on USAA Life would be.

  Pursuant to state insurance laws and regulations, USAA Life is obligated to
carry on its books, as liabilities, reserves to meet its obligations under
outstanding insurance contracts.  These reserves are based on assumptions about,
among other things, future claims experience and investment returns.  Neither
the reserve requirements nor the other aspects of state insurance regulation
provide absolute protection to holders of insurance contracts, including the
Contracts, if USAA Life were to incur claims or expenses at rates significantly
higher than expected, or significant unexpected losses on its investments.

  USAA Life has entered into a Service Agreement with USAA Transfer Agency
Company d/b/a USAA Shareholder Account Services ("USAA SAS"), pursuant to which
USAA SAS will receive and forward to USAA Life applications and premium payments
for certain Tax Sheltered Annuity Contracts.


                          TAX SHELTERED ANNUITY LOANS
                                        
  Loans are not currently available under the Contract.  USAA Life may in the
future, at its discretion, permit loans in connection with Contracts that fund
section 403(b) Tax Sheltered Annuities ("TSAs").  Any such loans must conform to
the requirements mandated by Section 72(p) of the Internal Revenue Code. If you
borrow against the Fixed Fund Account and/or Variable  Fund Account(s), the
portion equal to the loan amount will be transferred from the particular
Account(s) to a "Loan Collateral Account." The "Loan Collateral Account" is part
of the Company's general assets and liabilities.

  Loans are not available on TSA Contracts where the TSA plan is subject to the
Title I of the Employee Retirement Income Security Act (ERISA).  Also, loans are
not permitted when the Systematic Withdrawal Program has been elected or when
the Contract has been annuitized.  If you have taken a loan in the past which is
still outstanding, limits for any subsequent loans will be reduced by the amount
of the outstanding loan plus accrued interest.  Any renegotiation of an existing
loan becomes a new loan for tax purposes.

  The amount of the loan you may obtain should they become available depends
upon your Contract Value as shown below.  The maximum loan amount may not exceed
an aggregate of $50,000 on all TSA accounts.  The minimum loan amount is $2,500.

       CONTRACT VALUE                 MAXIMUM LOAN AMOUNT
       --------------                 -------------------
         $0 - $99,999                    50% of Account Balance*
         $100,000 or more                $50,000*

*  Internal Revenue Code requirements may be subject to change.

  Only one TSA loan may be requested in any twelve month period.  A TSA loan
must be repaid within a maximum of five years. Because the amount of the loan
may be removed from both the Fixed Fund Account and/or Variable  Fund
Account(s), a loan will have a permanent effect on the Contract Value. The
longer the loan is outstanding the greater the effect is likely to be.

  The loan must be repaid on a monthly schedule amortized over the term of the
loan.  The loan may be prepaid in full or in part at any time.  Loan payments
will be due as agreed upon at the time of the loan approval.  An amount equal to
the amount of loan repayment will be transferred from the Loan Collateral
Account to the Fixed Fund Account and the Variable Fund Account(s) in the same
proportion as purchase payments are currently allocated, unless the Contract
owner ("Owner") requests otherwise.

  The entire loan balance must be repaid before a withdrawal from the Contract
or before annuitization begins.  If the loan is repaid in full before the end of
the loan term, loan interest due will be prorated and an appropriate credit will
be provided.  Upon the death of the Owner, the death benefit will be reduced by
the outstanding loan balance and loan interest.

  A TSA loan is not a taxable distribution if the loan does not exceed the
maximum limitations and repayment does not become overdue. If a default in loan
repayment occurs, USAA Life Insurance Company may declare the entire outstanding
loan balance, plus interest plus any Fixed Fund Account Withdrawal Charge stated
in the Contract also immediately due and payable. Please note that a default as
to any installment payment under your loan amortization schedule may have
adverse tax consequences possibly subjecting you to tax on the defaulted payment
or possibly the 

                                       3
<PAGE>
 
entire value of the amount of the loan, plus payment of the 10% distribution
penalty if prior to age 59 1/2. Such a distribution will include any applicable
federal income tax withholding and state taxes, if any. We recommend that you
consult with a professional advisor regarding your particular tax situation.

  Before a loan can be made under a TSA Contract, a properly completed Written
Request and Loan Agreement must be signed.  A Loan Agreement can be obtained by
calling our toll free number 1-800-531-4265 and requesting a copy from a
representative at our Service Office.


                              INDEPENDENT AUDITORS
                                            
  The audited financial statements of the Separate Account included in its
Annual Report and the audited consolidated financial statements of USAA Life
Insurance Company and its subsidiaries as of December 31, 1998 and 1997 and for
each of the years in the three-year period ended December 31, 1998 have been
included in the Annual Report and the registration statement in reliance upon
the accompanying reports thereon of KPMG LLP, independent certified public
accountants, through their offices located at 112 East Pecan, Suite 2400, San
Antonio, Texas 78205, and upon the authority of said firm as experts in
accounting and auditing.     


                                 LEGAL MATTERS
                                        
  The legal validity of the Contracts has been passed upon by Richard T.
Halinski, Jr., Esq., of the legal department of USAA Life.  Freedman, Levy,
Kroll & Simonds, Washington D.C., has advised USAA Life on certain federal
securities law matters.


                    CALCULATION OF ACCUMULATION UNIT VALUES
                                        

  Each Variable Annuity Fund Account's Accumulation Units are valued separately.
Initially, the Accumulation Unit Value of each Variable Annuity Fund Account was
set at $10, except for the Money Market Fund Variable Annuity Fund Account,
which was set at $1.  Thereafter, the Accumulation Unit Value of a Variable
Annuity Fund Account as of the end of any Valuation Period is calculated as one
(1) multiplied by two (2) where:

(1)  is the Accumulation Unit Value for the Account as of the end of the
     immediately preceding Valuation Period; and
(2)  is the net investment factor for the Valuation Period then ended.


NET INVESTMENT FACTOR
- ---------------------

  The net investment factor ("NIF") is used to determine how the investment
experience of a Fund affects the Accumulation Unit Value of the corresponding
Variable Fund Account from one Valuation Period to the next Valuation Period.
The Valuation Period is the period of time from the end of one Valuation Date to
the end of the next Valuation date.  The Valuation Date is any business day,
Monday through Friday, on which the New York Stock Exchange is open for regular
trading, except:  (1) any day on which the value of the shares of a Fund is not
computed; and (2) any day during which no order for the purchase, redemption,
surrender or transfer of Accumulation Units or Annuity Units is received.

  The NIF for each Variable Fund Account as of the end of any Valuation Period
is determined by dividing (1) by (2) and subtracting (3) from the result where:

1.  Is the net result of:

     (a) the net asset value per share of the corresponding Fund as of the end
of the current Valuation Period;

                                       4
<PAGE>
 
     (b)  plus the per share amount of any dividend or capital gain
          distributions made on the Fund shares held in the corresponding
          Variable  Fund Account during the current Valuation Period;

     (c)  plus or minus a per share credit or charge for that current Valuation
          Period for any decrease or increase, respectively, in any income taxes
          reserved that we determine has resulted from the investment operations
          of the particular Variable  Fund Account or any other taxes that are
          applicable to this Contract;

(2)  Is the net asset value per share of the corresponding Fund at the beginning
     of the current Valuation Period; and

(3)  Is a factor representing the mortality and expense risk and administrative
     expense charge.  The annual charge is 0.75% (0.65% for the mortality and
     expense risk charge and 0.10% for the administrative expense charge).


                     CALCULATION OF PERFORMANCE INFORMATION
                                        
  From time to time, the Separate Account may include in advertisements, sales
literature, and reports to contract owners or prospective investors information
relating to the performance of its Variable Fund Accounts.  The performance
information that may be presented is not an estimate or guarantee of future
investment performance and does not represent the actual experience of amounts
invested by a particular Owner.  Set out below is a description of the
standardized and non-standardized methods used in calculating the performance
information for the Variable Fund Accounts.  All standardized performance
quotations will reflect the deduction of the Mortality and Expense Risk Charge,
the Administrative Expense Charge and the Contract Maintenance Charge, based on
an estimated average Contract size of $39,030 and Fund operating expenses (net
of reimbursements), but will not reflect charges for any state premium taxes.
The Contracts are not subject to a charge for withdrawals from any Variable
Fund Account.


USAA LIFE  MONEY MARKET FUND ACCOUNT
- ------------------------------------

  YIELD and EFFECTIVE YIELD quotations for the USAA Life Money Market Fund
Account are computed in accordance with standard methods prescribed by the SEC.
Under these methods, the USAA Life Money Market Fund Account's yield is
calculated based on a hypothetical Contract having a beginning balance of one
Accumulation Unit in the USAA Life  Money Market Fund Account for a specified
seven-day period.  Yield is determined by dividing the net change in the
Accumulation Unit Value during the seven-day period, reduced by the estimated
daily equivalent of the Contract Maintenance Charge, by its beginning value to
obtain the base period return, then multiplying the base period return by the
fraction 365/7.  The net change in Accumulation Unit Value will reflect the
value of additional shares purchased with the dividends paid by the Trust, but
will not reflect any realized capital gains or losses or unrealized appreciation
or depreciation in the assets of the Variable  Fund Account.

  The effective yield of the USAA Life Money Market Fund Account reflects the
effects of compounding, and is computed according to the following formula
prescribed by the SEC:

                                                        365/7
             Effective Yield = [(Base Period Return + 1)     ] - 1

  For the seven day period ended December 31, 1998, the current yield of the
USAA Life Money Market Fund Account was 4.16%.


OTHER VARIABLE  FUND ACCOUNTS
- -----------------------------

  Each Variable Fund Account may state its TOTAL RETURN or YIELD in sales
literature and advertisements.  Any statements of total return, yield, or other
performance data of a Variable Fund Account, other than yield quotations of 

                                       5
<PAGE>
 
the USAA Life Money Market Fund Account, will be accompanied by information on
that Variable Fund Account's standardized average annual total return for the
most recent 1, 5, or 10 year periods or, if less, the period from the Variable
Fund Account's inception of operation.


  AVERAGE ANNUAL TOTAL RETURN.  Standardized average annual total return is
computed according to the following formula prescribed by the SEC, based on a
hypothetical $1,000 Contract Value:

                                         n
                                P (1 + T)  = ERV

Where:
   P =  A hypothetical initial premium payment of $1,000.
   T =  Average annual total return.
   n =  Number of years.
 ERV =  Ending redeemable value of a hypothetical $1,000 Contract Value at the
        end of the period.

  Non-standardized average annual total return is computed in a similar manner,
except that different time periods and hypothetical initial payments may be
used, and certain charges may not be reflected.

  CUMULATIVE TOTAL RETURN.  Cumulative total return is calculated in a manner
similar to standardized average annual total return, except that the results are
not annualized.  The SEC has not prescribed a standard formula for calculating
cumulative total return.  Cumulative total return is calculated by finding the
cumulative rates of return of a hypothetical initial investment of $1,000 over
various periods, according to the following formula, and then expressing that as
a percentage:

                                C = (ERV/P) - 1

Where:
   P = A hypothetical initial payment of $1,000.
   C = Cumulative total return.
 ERV = Ending redeemable value of a hypothetical $1,000 payment made at the
       beginning of the applicable period.

  The standardized average annual total returns and the cumulative total returns
for each Variable Fund Account for periods ended December 31, 1998 were as
follows:

*  The three year average annual total return and three year cumulative total
return are calculated using the applicable formulas described above.

  30-DAY YIELD.  Each Variable Fund Account, other than the USAA Life Money
Market Fund Account, may also advertise its yield based on a specified 30-day
period.  Yield is determined by dividing the net investment income per
Accumulation Unit earned during the 30-day period  by the Accumulation Unit
Value on the last day of the period and annualizing the resulting figure,
according to the following formula prescribed by the SEC, which assumes a semi-
annual reinvestment of income:

                                           6 
                        YIELD =2  [(a-b +1)  -1]
                                    ---         
                                  [(cd    )    ]

                                       7
<PAGE>
 
Where:
 a = Net investment income earned during the period by the Fund whose shares
     are owned by the Variable Fund Account.
 b = Expenses accrued for the period.
 c = The average daily number of Accumulation Units outstanding during the
     period.
 d = The maximum offering price per Accumulation Unit on the last day of the
     period.


                                ANNUITY PAYMENTS
                                        
GENDER OF ANNUITANT
- -------------------

  When annuity payments are based on life expectancy, the amount of each annuity
payment ordinarily will be higher if the Annuitant or other measuring life is a
male, as compared with a female under an otherwise identical Contract, because,
statistically, females tend to have longer life expectancies than males.

  However, there will be no differences between males and females in any
jurisdiction, including Montana, where such differences are not permitted.  We
may also make available Contracts with no such differences in connection with
certain employer-sponsored benefit plans.  Employers should be aware that under
most such plans, Contracts that make distinctions based on gender are prohibited
by law.


MISSTATEMENT OF AGE OR SEX AND OTHER ERRORS
- -------------------------------------------

  If the age or sex of an Annuitant has been misstated to us, any amount payable
will be that which the premium payments paid would have purchased at the correct
age and sex.  If we made any overpayments because of incorrect information about
age or sex, or any error or miscalculation, we will deduct the overpayment from
the next payment or payments due.  We will add any underpayments to the next
payment.  The amount of any adjustment will be credited or charged with interest
at the effective annual rate of 3% per year.


ANNUITY UNIT VALUE
- ------------------

  Annuity Unit Value is calculated at the same time that Accumulation Unit Value
is calculated and is based on the same values for shares of the Funds.  The
following illustrations show, by use of hypothetical examples, the methods of
determining the Annuity Unit Value and the amount of Variable Annuity Payments.

The Board of Directors
USAA LIFE INSURANCE COMPANY:

We have audited the accompanying consolidated balance sheets of USAA LIFE
INSURANCE COMPANY and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, comprehensive income, stockholders'
equity, and cash flows for each of the years in the three-year period ended
December 31, 1998.  These consolidated financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of USAA LIFE INSURANCE
COMPANY and subsidiaries as of December 31, 1998, and 1997, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1998 in conformity with generally accepted accounting
principles.

(1)  Summary of significant accounting policies
     ------------------------------------------

     (a)  Organization
          ------------

          USAA LIFE INSURANCE COMPANY (the Company) is a wholly-owned subsidiary
          of UNITED SERVICES AUTOMOBILE ASSOCIATION (USAA). The Company markets
          individual life insurance policies, annuity contracts, and individual
          and group accident and health policies primarily to individuals
          eligible for membership in USAA. The Company is licensed to do
          business in all states including the District of Columbia but
          excluding New York. The Company has a subsidiary company (USAA Life
          Insurance Company of New York) licensed to sell life and annuity
          contracts in that state. The Company's other subsidiary business (USAA
          Life General Agency) offers additional products of other insurance
          companies requested by USAA membership, which are not sold by the
          Company. The consolidated financial statements include the accounts of
          the Company and its subsidiaries. All significant intercompany
          balances and transactions have been eliminated in consolidation.



     (b)  Accounting standards adopted
          ----------------------------

          The Company adopted Statement of Financial Accounting Standard No.
          125, "Accounting for Transfers and Servicing of Financial Assets and
          Extinguishments of Liabilities", on January 1, 1997. SFAS No. 125
          established criteria for determining whether transfers of financial
          assets are sales or secured borrowings. The adoption of this statement
          resulted in the recording of an asset and corresponding liability
          representing the collateral received in connection with the Company's
          securities lending program. The collateral held is recorded in
          "Collateral for securities loaned at fair value" with the off setting
          liability being reflected in "Payable upon return of securities
          loaned." This accounting treatment has no effect on the Company's net
          earnings or stockholders' equity.

          The Company adopted SFAS No. 130, "Reporting Comprehensive Income" on
          January 1, 1998. This statement establishes standards for reporting
          and presentation of comprehensive income and its components in a full
          set of financial statements. Comprehensive income consists of net
          income and net unrealized gains (losses) on securities and is
          presented in the consolidated statements of comprehensive income. SFAS
          No. 130 requires only additional disclosures in the consolidated
          financial statements; it does not affect the Company's financial
          position, results of operations, or liquidity.

          The Company adopted SFAS No. 131, "Disclosures about Segments of an
          Enterprise and Related Information" on January 1, 1998. This statement
          provides standards for reporting information about operating segments
          in financial statements using the "management approach."

          The Company adopted the provisions of the AICPA Statement of Position
          (SOP) 98-1, "Accounting for the Costs of Computer Software Developed
          or Obtained for Internal Use" on January 1, 1998. This SOP requires
          that certain costs of computer software developed or obtained for
          internal use be capitalized and amortized over the estimated useful
          life of the software. Adoption of this SOP did not have a material
          impact on the Company's financial position, results of operations, or
          liquidity.


                                                                    (Continued)

     (c)  Investments
          -----------

          Debt securities, including bonds, mortgage-backed securities (MBS's),
          and redeemable preferred stocks, have been classified as either held-
          to-maturity or available-for-sale. Debt securities classified as held-
          to-maturity are carried at amortized cost. Securities classified as
          available-for-sale are carried at fair value with unrealized gains or
          losses (net of related deferred income taxes, deferred policy
          acquisition costs, and insurance reserves) reflected in stockholders'
          equity.

          Bonds, at amortized cost of approximately $289,788, and $281,206 were
          on deposit with various state governmental agencies at December 31,
          1998, and 1997, respectively. When the New York subsidiary was formed
          in 1997, the Company withdrew its license in the State of New York. To
          be in compliance with the New York Regulation 109, the 1998 and 1997
          deposits include $286,825 and $278,333, respectively, held for the
          security of the New York policyholders.

          Mortgage-backed securities held represent participating interests in
          pools of long term first mortgage loans originated and serviced by the
          issuers of the securities. Market interest rate fluctuations can
          affect the prepayment speed of principal and the yield on the
          securities.

          All equity securities, which include common and non-redeemable
          preferred stocks, have been classified as available-for-sale. Equity
          securities are carried at fair value with unrealized gains or losses
          (net of related deferred income taxes, deferred policy acquisition
          costs, and insurance reserves) reflected in stockholders' equity.

          Mortgage and policy loans are carried at their unpaid principal
          balances with interest rates ranging from 4.80% to 10.0% at December
          31, 1998.

          Short-term securities are carried at cost.

          Interest is not accrued on debt securities or mortgage loans for which
          principal or interest payments are determined to be uncollectible.

          Realized gains and losses are included in net income based upon
          specific identification of the investment sold. When impairment of the
          value of an investment is considered to be other than temporary, a
          provision for the writedown to estimated net realizable value is
          recorded. Net realized capital gains of $56,720, $0, and $0 for 1998,
          1997, and 1996 respectively, allocable to future policyholder
          dividends and interest, were deducted from net realized capital gains
          and an offsetting amount was reflected in insurance reserves.

     (d)  Cash and cash equivalents
          -------------------------

          For purposes of the consolidated statement of cash flows, all highly
          liquid marketable securities that have a maturity at purchase of three
          months or less and money market mutual funds are considered to be cash
          equivalents. At December 31, 1998 and 1997, cash and cash equivalents
          include $760 and $268, respectively, of separate account purchases
          awaiting reinvestment. These funds are restricted from the Company's
          use.

                                                                     (Continued)

     (e)  Federal income taxes
          --------------------

          The Company and its subsidiaries are included in the consolidated
          Federal income tax return filed by USAA. Taxes are allocated to the
          separate companies of USAA based on a tax allocation agreement,
          whereby companies receive a current benefit to the extent their losses
          are utilized by the consolidated group. Separate company current taxes
          are the higher of taxes computed at a 35% rate on regular taxable
          income or taxes computed at a 20% rate on alternative minimum taxable
          income, adjusted for any consolidated benefits allocated to the
          companies based on the use of separate company losses within the
          group.

          Deferred income taxes are recognized for the tax consequences of
          "temporary differences" by applying enacted statutory tax rates
          applicable to future years to differences between the financial
          statement carrying amounts and the tax bases of existing assets and
          liabilities. The effect on deferred income taxes of a change in tax
          rates is recognized in income in the period that includes the
          enactment date.

     (f)  Fair value of financial instruments
          -----------------------------------

          The fair value estimates of the Company's financial instruments are
          made at a point in time, based on relevant market information about
          the related financial instrument. These estimates do not reflect any
          premium or discount that could result from offering for sale at one
          time the Company's entire holding of a particular financial
          instrument. In addition, the tax ramifications related to the effect
          of fair market value estimates have not been considered in the
          estimates.

     (g)  Use of estimates
          ----------------

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

     (h)  Deferred policy acquisition costs
          ---------------------------------

          Policy acquisition costs, consisting primarily of certain underwriting
          and selling expenses, are deferred and amortized. Traditional
          individual life and health acquisition costs are amortized in
          proportion to anticipated premium income after allowing for lapses and
          terminations (20 years; but not to exceed the life of the policy).
          Acquisition costs for universal life and annuities are amortized in
          relation to the present value of estimated gross profits from
          surrender charges and investment, mortality and expense margins (20
          years).

          Deferred policy acquisition costs are reviewed to determine that the
          unamortized portion does not exceed expected future income or gross
          profits.

                                                                     (Continued)

     (i)  Insurance reserves
          ------------------

          Included in insurance reserves are traditional life and health
          products and payout annuities with life contingencies. Payout
          annuities without life contingencies, deferred annuities, and
          universal life products are classified as funds on deposit.
          Traditional life and individual health reserves are computed using a
          net level premium method and are based on assumed or guaranteed
          investment yields and assumed rates of mortality, morbidity,
          withdrawals, expenses and anticipated future policyholder dividends.
          These assumptions vary by such characteristics as plan, year of issue,
          policy duration, date of receipt of funds, and may include provisions
          for adverse deviation.

     (j)  Insurance revenues and expenses
           -------------------------------

          Premiums on traditional life insurance products are recognized as
          revenues as they become due. Benefits and expenses are matched with
          premiums in arriving at profits by providing for policy benefits over
          the lives of the policies and by amortizing acquisition costs. For
          universal life and investment annuity contracts, revenues consist of
          investment earnings and policy charges for the cost of insurance,
          policy administration, and surrender charges assessed during the
          period. Expenses for these policies include interest credited to
          policy account balances, benefit claims incurred in excess of policy
          account balances, and administrative expenses. The related deferred
          policy acquisition costs are amortized in relation to the present
          value of expected gross profits from surrender charges and investment,
          mortality, and expense margins.


     (k)  Funds on deposit
          ----------------

          Funds on deposit are liabilities for universal life and investment-
          related products. These liabilities are determined following the
          "retrospective deposit" method and consist principally of policy
          account balances before applicable surrender charges.

     (l)  Participating business
          ----------------------

          Certain life insurance policies contain dividend payment provisions
          which enable the policyholder to participate in the earnings of the
          life insurance operations. The participating insurance in force
          accounted for 7% of the total life insurance in force at December 31,
          1998, and 8% of life insurance in force at December 31, 1997.
          Participating policies accounted for 16% of the premium income in
          1998, and 13% of the premium income in 1997. The provision for
          policyholders' dividends is based on current dividend scales.

          The Company guarantees to pay dividends in aggregate, on all
          participating policies issued after December 31, 1983, in the total
          amount of $16,897 in 1999.

          Income attributable to participating policies in excess of
          policyholder dividends is restricted by several states for
          participating policyholders of those states, otherwise income in
          excess of policyholder dividends is accounted for as belonging to the
          stockholders.

      (m) Reclassifications
          -----------------

          Certain reclassifications of prior period amounts have been made to
          conform with the current year's presentation.

                                                                     (Continued)

(2)  Basis of accounting
     -------------------

     The Company prepares separate statutory financial statements in accordance
     with accounting practices prescribed or permitted by the Texas Department
     of Insurance. Prescribed statutory accounting practices include a variety
     of publications of the NAIC as well as state laws, regulations, and general
     administrative rules. Permitted statutory accounting practices encompass
     all accounting practices not so prescribed. The NAIC has adopted
     codification for standard accounting practices, which will be implemented
     in 2001. It is currently unknown which states will adopt codification.

     These consolidated financial statements have been prepared on the basis of
     generally accepted accounting principles (GAAP), which differs from the
     basis of accounting followed in reporting to insurance regulatory
     authorities. Reconciliations of statutory net income and capital and
     surplus, as determined using statutory accounting principles, to the
     amounts included in the accompanying consolidated financial statements are
     as follows:

  Proceeds from sales of available-for-sale securities during 1998, 1997, and
  1996 were $399,619, $317,851, and $495,039, respectively.  Gross gains and
  losses of $65,670 and $2,794 respectively for 1998, and $29,049 and $2,913
  respectively for 1997, and $25,566 and $18,317 respectively for 1996, were
  realized on those sales.

  Gross investment income during 1998, 1997, and 1996 was $480,350, $456,322,
  and $431,893, respectively, and consists primarily of interest income on fixed
  maturity securities. Investment expenses were $4,219,  $4,218, and  $3,732 for
  1998, 1997, and 1996, respectively.

  The Company engages in securities lending whereby certain securities from its
  portfolio are loaned to other institutions for short periods of time.  Initial
  collateral, primarily cash, is required at a rate of 102% of the market value
  of a loaned security.  The collateral is deposited by the borrower with a
  lending agent, and retained and invested by the lending agent according to the
  Company's guidelines to generate additional income.  The market value of the
  loaned securities is monitored on a daily basis with additional collateral
  obtained or refunded as the market value of the loaned securities fluctuates.

  Deferred income tax benefit for the years ended December 31, 1998, 1997, and
  1996 was primarily attributable to differences between the valuation of assets
  and insurance liabilities for financial reporting and tax purposes.

(5)  Fair value of financial instruments
     -----------------------------------

     The following tables present the carrying amounts and estimated fair values
     of the Company's financial instruments at December 31. SFAS No. 107,
     "Disclosures about Fair Value of Financial Instruments", defines the fair
     value of a financial instrument as the amount at which the instrument could
     be exchanged in a current transaction between willing parties.

     All carrying amounts are included in the balance sheet under the indicated
     captions, except for deferred annuities and annuities without life
     contingencies, and policyholder dividend accumulations both of which are
     included in funds on deposit, and policy dividends declared but unpaid
     which are included in other liabilities.

     The following methods and assumptions were used to estimate the fair value
     of each class of financial instruments:

     Cash and cash equivalents: Cash and cash equivalents approximate fair value
     because of the short maturity of these instruments.

     Debt and equity securities: Fair market values for bonds and stocks are
     determined using quoted market prices from Merrill Lynch Pricing Services,
     Bloomberg Services or individual brokers.

     Mortgage loans: The fair value of mortgage loans are estimated by
     discounting the future cash flows using interest rates currently being
     offered for mortgage loans with similar characteristics and maturities.

     Policy loans: In the Company's opinion, the book value of the policy loans
     approximates their fair value. Policy loans are shown on the financial
     statements at face value, and carry interest rates ranging from 4.8% to
     7.4% in advance.

                                                                     (Continued)

                             (Dollars in Thousands)


     Premiums receivable: The recorded amount for premiums receivable
     approximates fair value because only a slight percentage of total policies
     issued by the Company lapse.

     Accrued investment income: The accrued amount of investment income
     approximates its fair value because of the quality of the Company's
     investment portfolio combined with the short-term nature of the collection
     period.

     Deferred annuities and annuities without life contingencies: The fair value
     of the deferred annuities is estimated as the aggregate cash value of the
     annuity, which approximates the carrying value. The fair value of annuities
     without life contingencies is estimated as the commuted value of the
     annuity.

     Policyholder dividend accumulations: The fair value of policyholder
     dividend accumulations is estimated using the book value less a percentage
     of accrued interest anticipated to be forfeited as a result of policy
     cancellations. Estimated annual interest to be forfeited is not
     significant.

     Policy dividends declared but unpaid: The carrying value of policy
     dividends declared but unpaid approximates the fair value because the
     carrying value reflects anticipated forfeitures as a result of policy
     cancellations. Estimated annual interest to be forfeited is not
     significant.

     Accounts payable and accrued expenses: The fair value of accounts payable
     and accrued expenses approximates its carrying value because of the short-
     term nature of the obligations.

     Separate account assets and liabilities: The separate account assets
     reflect the net asset value of the underlying mutual funds, therefore,
     carrying value is considered fair value. The separate account liabilities
     are reflected at the underlying balances due to the contract holders,
     excluding seed money, without consideration for applicable surrender
     charges, if any.

(6)  Borrowings
     ----------

     The Company has no borrowing activity outside of the agreements described
     in Note 7 "Transactions with affiliates."

(7)  Transactions with affiliates
     ----------------------------

     Certain services have been contracted from USAA and its affiliates, such as
     rental of office space, utilities, mail processing, data processing,
     printing, and employee benefits. The Company allocates these and other
     expenses to affiliates for administrative services performed by the
     Company. The contracted services and allocations are based upon various
     formulas or agreements with the net amounts included in expenses. The
     aggregate amount of such contracted services was $127,604, $73,136, and
     $70,713 for 1998, 1997, and 1996, respectively. The aggregate amount of the
     Company's allocations to affiliates was $6,553, $4,376, and $4,742 for
     1998, 1997, and 1996, respectively.

     The Company has an agreement with USAA Investment Management Company
     regarding the reimbursement of costs for investment services provided. The
     aggregate amount of the USAA Investment Management Company contracted
     services was $3,600, $3,039, and $2,793 for 1998, 1997 and 1996,
     respectively.

                                                                     (Continued)

                             (Dollars in Thousands)


     The Company also received premium and annuity considerations from USAA of
     $4,319, $4,201, and $4,093 in 1998, 1997, and 1996, respectively,
     representing amounts received for structured settlements issued to
     claimants of USAA and for group insurance on USAA employees.

     The Company has intercompany funding agreements with USAA Capital
     Corporation (CAPCO) and USAA Funding Company (FUNDCO) for unsecured
     borrowings up to $150,000 in the aggregate, at an interest rate based upon
     CAPCO's or FUNDCO's cost of funding. As of December 31, 1998, 1997, and
     1996 the Company had no liability for borrowed money. The Company borrowed
     $271,553, $3,598,125, and $2,566,042 during 1998, 1997 and 1996
     respectively, through the use of these funding agreements. The interest
     associated with these intercompany-funding agreements was $76, $855, and
     $660 in 1998, 1997, and 1996, respectively.


(8)  Reinsurance
     -----------

     The Company is party to several reinsurance agreements. The Company's
     general policy is to reinsure that portion of any risk in excess of $600
     with a $100 corridor on the life of any one individual. However in 1997 the
     Company entered into certain reinsurance treaties which are based on a
     first dollar quota share pool. The Company retains 10% of the risk on each
     life up to the normal $600 retention and the remaining 90% is ceded to a
     coinsurance pool which is placed with a number of reinsurers on a quota
     share basis.

     The Company assumes Bank Owned Life Insurance (BOLI) business through two
     reinsurance treaties, one Yearly Renewable Term (YRT) and one Coinsurance
     treaty, both of which are with one reinsurer on a first dollar basis, with
     the Company retaining 50% of the business under the coinsurance
     arrangement.

     Although the ceding of reinsurance does not discharge the Company from its
     primary legal liability to a policyholder, the reinsuring company assumes
     the related liability.

     Life insurance in force in the amounts of $4,500,994, $4,087,549, and
     $3,595,801 is ceded on a yearly renewable term basis; $10,982,455,
     $4,687,456, and $939,290 is ceded on a coinsurance basis; and $1,562,383,
     $957,925, and $952,599 is ceded in accordance with a stop loss agreement at
     December 31, 1998, 1997, and 1996, respectively. Reinsurance amounts
     related to insurance reserves, funds on deposit, and paid losses totaled
     $308,262 and $204,626 at December 31, 1998 and 1997, respectively. Premium
     revenues and interest credited to policyholders were reduced by $104,262,
     $204,123, and $11,837 for reinsurance premiums ceded during the years ended
     December 31, 1998, 1997, and 1996, respectively. Benefits were reduced by
     $114,351, $196,080, and $7,838 for reinsurance recoverables during the
     years ended December 31, 1998, 1997, and 1996, respectively.

     In accordance with accident and health reinsurance contracts, aggregate
     reserves for policies and contracts and policy and contract claims are
     reduced by $23,868 and $17,981 at December 31, 1998 and 1997, respectively.
     Premium revenues were reduced by $3,266, $3,297, and $3,117 for reinsurance
     premiums ceded during the years ended December 31, 1998, 1997, and 1996,
     respectively. Benefits were reduced by $6,082, $3,268, and $3,604 for
     reinsurance recoverables during the years ended December 31, 1998, 1997,
     and 1996, respectively.

                                                                     (Continued)

  Life Insurance and Annuities:

  Interest assumptions used in the calculation of future policy benefits for
  Traditional Life policies are as follows:

  Participating term                        9.28%

  Participating permanent                   8.68% to 9.28%

  Non - Participating term                  6.00% to 8.91%

  Future policy benefits for Universal Life and Deferred Annuities are equal to
  the current account value without anticipation of any applicable surrender
  charges.

  Future policy benefits for Payout Annuities use the original pricing interest
  rates.

  Mortality and withdrawal assumptions are based on the Company's experience.

  Health Insurance:

  Interest assumptions used for future policy benefits on health policies are
  calculated using a level interest rate of 6%.

  Morbidity for Income Replacement policies are based on the 1985 CIDA table.
  Morbidity for In Hospital Cash policies are based on 1966-67 Intercompany
  Experience table.

  Termination assumptions are based on the Company and industry experience.

                                                                     (Continued)

(10)  Capital stock
      -------------

      The Company has outstanding 600,000 shares of Annually Adjustable
      Cumulative Perpetual Preferred Stock; 100,000 shares each of Series A,
      Series B, Series C, Series D, Series E, and Series F. All preferred stock
      is owned by FUNDCO. No other stock ranks Senior to the Series A-F
      preferred stock. The dividend rate will be 65% of the cost of the funds
      for CAPCO on commercial paper having a 180-day maturity on the first
      business day of each dividend period. The preferred stock has a par value
      of $100 and a liquidation value of $100 per share. The preferred stock
      shares are redeemable at the option of the Company for cash, in whole or
      in part, on the 15th day of each December for Series A and Series B and on
      the 15th day of each June for Series C, Series D, Series E, and Series F
      at par value plus accrued and unpaid dividends. Preferred stock dividends
      of $2,229, $2,200, and $1,830 were paid in 1998, 1997, and 1996
      respectively, and $81 and $94 were accrued for each year after the last
      payments on December 15, 1998 and 1997, respectively.

      The Company has authorized 30,000 shares of common capital stock, $100 par
      value, of which 25,000 shares were issued and outstanding at December 31,
      1998, 1997, and 1996. Dividends of $134,428, $45,546, and $14,000 were
      paid on the common stock during 1998, 1997, and 1996, respectively. The
      equity securities transferred had an original cost of $21,951, $11,560,
      $0, a fair value of $33,928, $22,546 and $0, and a realized gain of
      $11,977, $10,986, and $0 in 1998, 1997 and 1996, respectively.


(11)  Unassigned surplus and dividend restrictions
      --------------------------------------------

      Texas law limits the payment of dividends to shareholders. The maximum
      dividend that may be paid without prior approval of the Insurance
      Commissioner is limited to the greater of net gain from operations of the
      preceding calendar year or 10% of capital and surplus as of the prior
      December 31. As a result, dividend payments to shareholders were limited
      to approximately $66,910 in 1998 and are limited to $56,811 in 1999.
      Dividends are paid as determined by the Board of Directors and at its
      discretion. Extraordinary dividends approved by the Texas Department of
      Insurance, totaling $69,785, $0 and $0 were paid in 1998, 1997 and 1996,
      respectively.

      The Texas Department of Insurance imposes minimum risk-based capital
      requirements on insurance companies that were developed by the National
      Association of Insurance Commissioners (NAIC). The formulas for
      determining the amount of risk-based capital (RBC) specify various
      weighting factors that are applied to statutory financial balances or
      various levels of activity based on the perceived degree of risk.
      Regulatory compliance is determined by a ratio of the Company's regulatory
      total adjusted capital to its authorized control level RBC, as defined by
      the NAIC. Companies below specific trigger points or ratios are classified
      within certain levels, each of which requires specified corrective action.
      The Company's current statutory capital and surplus is significantly in
      excess of the threshold RBC requirements.


(12)  Business Segments
      -----------------

      The significant business segments of the Company are life insurance,
      annuity products, and health insurance which are marketed primarily to
      individuals eligible for membership in USAA. The life insurance segment
      offers universal life, whole life, term, and other individual coverages.
      The annuity segment offers both fixed and variable annuity products. The
      health segment offers individual and group accident and health policies.

                                                                     (Continued)

                   Notes to Consolidated Financial Statements

                             (Dollars in Thousands)


(13)  Employee benefit plans
      ----------------------

      (a)  Pension plan
           ------------

           Substantially all employees are covered under a pension plan
           administered by USAA which is accounted for on a group basis. The
           benefits are determined based on years of service and the employee's
           salary at date of retirement. The total net pension cost allocated to
           the Company on the basis of salary expense was $4,422, $3,746, and
           $4,847 in 1998, 1997 and 1996, respectively. At December 31, 1998 and
           1997, a liability of $0 and $899, respectively, has been recorded
           which represents the excess of net periodic pension cost allocated to
           the Company over its allocated funding requirements.

      (b)  Postretirement benefit plan
           ---------------------------

           Substantially all employees of the Company may become eligible for
           certain medical and life insurance benefits provided for retired
           employees under a plan administered by USAA if they meet minimum age
           and service requirements and retire while working for USAA. The
           postretirement benefit cost allocated to the Company based on the
           number of employees was $1,084, $737 and $682 in 1998, 1997 and 1996,
           respectively. At December 31, 1998 and 1997, a liability of $2,097
           and $974, respectively, has been recorded which represents the under-
           funding of the Company's allocated funding requirements under the net
           periodic postretirement benefit cost allocated to the Company.

      (c)  Contributory retirement plan
           ----------------------------

           Substantially all employees of the Company and its subsidiaries are
           eligible to participate in USAA's contributory retirement plan. The
           Company matches participant contributions dollar for dollar to a
           maximum of 6% of a participant's compensation. The Company's
           contributions vest on a graduated basis up to 100% after five years
           of credited service. In 1998 and 1997, the Company's contributions to
           the Plan totaled $2,415 and $2,122, respectively.

(14)  Separate account
      ----------------

      The Separate Account and the Life Insurance Separate Account are
      segregated asset accounts established under Texas law through which USAA
      Life Insurance Company invests the premium payments received from Contract
      Owners and Policy Owners, respectively. The assets of the Separate
      Accounts are the property of the Company. However, only the assets of the
      Separate Accounts in excess of the reserves, and other Contract
      liabilities with respect to the Separate Accounts, are chargeable with
      liabilities arising out of any other business the Company may conduct.
      Income, gains and losses, whether or not realized, are, in accordance with
      the Contracts and Policies, credited to or charged against the Separate
      Accounts without regard to other income, gains or losses of the Company.
      The Company's obligations arising under the Contracts are general
      corporate obligations.

                                                                     (Continued)

                   Notes to Consolidated Financial Statements

                             (Dollars in Thousands)


      The Separate Account currently is divided into twelve Variable Annuity
      Fund Accounts, each of which invests in a corresponding Fund. The Funds
      that are available under this Contract include seven funds of USAA Life
      Investment Trust, the Capital Growth Portfolio of the Scudder Variable
      Life Investment Fund, and the Growth Portfolio of the Alger American Fund,
      and three funds of the Bankers Trust Insurance Funds Trust series. The
      Accumulated Unit Value of the Contract in a Variable Fund Account will
      vary, primarily based on the investment experience of the Fund in whose
      shares the Variable Fund Account invests. The value of the Funds'
      securities are carried at market value, or, in the case of the USAA Life
      Variable Money Market Fund, at amortized cost, which approximates market
      value.

      The Company incurs mortality expenses on behalf of Separate Accounts
      contract holders and policy owners. The Company also incurs administrative
      expenses on behalf of contract owners. The Company collects fees for these
      expenses from contract holders and policy owners, respectively at set
      amounts. In addition, the Company incurs various expenses related to
      conducting the business or operations of the USAA Life Investment Trust
      (Trust) as outlined by an underwriting and administrative services
      agreement. The Company, out of its general account, has agreed to pay
      directly or reimburse the Trust for Trust expenses exceeding established
      limits. Such reimbursements were not significant in 1998 and 1997.


(15)  Year 2000
      ---------

      The Company has entered into contracts under which information technology
      support is provided by its affiliate, USAA Information Technology Company
      ("ITCO"), which is also an indirect, wholly-owned subsidiary of USAA. USAA
      established a Change of Century Program Management Office in 1994, and has
      since developed an extensive Change of Century Project Management Plan
      which is followed by ITCO personnel in the assessment, evaluation,
      testing, and certification of all systems utilized by the USAA companies,
      including the USAA Life Insurance Company.

      The Company, with assistance from ITCO and USAA, has also
      identified and contacted critical vendors and business partners whose
      computerized systems interface with the Company's systems, regarding their
      plans and progress in addressing their Year 2000 issues.

(16)  Commitments and contingencies
      -----------------------------

      The Company is required by law to participate in the guaranty associations
      of the various states in which it does business. The state guaranty
      associations ensure payment of guaranteed benefits, with certain
      restrictions to policyholders of impaired or insolvent insurance
      companies, by assessing all other companies involved in similar lines of
      business.

      There are currently several insurance companies which had substantial
      amounts of annuity business, in the process of liquidation or
      rehabilitation. The Company paid $1,898, $1,953 and $2,437 to various
      state guaranty associations during the years ended December 31, 1998,
      1997, and 1996, respectively. The Company accrues its best estimate for
      known insolvencies. At December 31, 1998 and 1997 accounts payable and
      accrued expenses include $6,052 and $8,931, respectively, related to
      estimated assessments.

      The Company is party to various lawsuits and claims generally incidental
      to its business. The ultimate disposition of these matters is not expected
      to have a significant adverse effect on the Company's financial position
      or results of operations.

                                                                     (Continued)

  Insofar as indemnification for liability arising under the Securities Act of
1933 (the "1933 Act") may be permitted for Directors, Officers and controlling
persons of USAA Life pursuant to the foregoing, or otherwise, USAA Life has been
advised that in the opinion of the Securities and Exchange Commission (the
"Commission"), such indemnification is against public policy as expressed in the
1933 Act and, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by USAA Life of
expenses incurred or paid by a Director, officer or controlling person of USAA
Life in the successful defense of any action, suit or proceeding) is asserted by
such Director, officer or controlling person in connection with the securities
being registered, USAA Life will, unless in the opinion of its counsel this
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 adjudication of such issue.
