VARIABLE ANNUITY
Flexible Premium Deferred Combination
Fixed amd Variable Annuity Contract
    
OFFERED BY
USAA Life Insurance Company
9800 Fredericksburg Road, San Antonio, Texas 78288
Telephone: (1-800-531-2923)                        Prospectus dated: May 1, 1998
     
- --------------------------------------------------------------------------------
    
  This Prospectus describes a Flexible Premium Deferred Combination Fixed and
Variable Annuity Contract ("Contract") that USAA Life Insurance Company ("USAA
Life" or the "Company") is offering to individual members and families of
members of the United Services Automobile Association ("USAA"), the parent
company of the USAA group of companies, as well as to the general public.
  The Contract is designed to assist individuals in planning for retirement and
other long-term purposes.  The Contract is available in connection with
retirement plans that may or may not qualify for special federal tax treatment
under the Internal Revenue Code (the "Code"), i.e. Qualified and Nonqualified
Plans.  (See "Tax Matters - Qualified Plans" below.)
  The Contract enables Contract owners ("Contract Owners" or "Owners") to earn a
fixed rate of interest declared by USAA Life from time to time by allocating
their premium payments under the Contract to the Fixed Fund Account of USAA
Life. The Fixed Fund Account may not be available in all states. (See "Fixed
Fund Account" below.) Contract Owners also may seek a variable investment return
by allocating their premium payments to the Separate Account of USAA Life (the
"Separate Account").  The Separate Account is a segregated investment account of
USAA Life, and currently is divided into twelve Variable Fund Accounts (referred
to herein as "Variable  Fund Accounts"), each of which invests in a
corresponding Fund. The Accumulated 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 Funds that are available under this Contract include:  seven Funds of USAA
Life Investment Trust (the "Trust"), namely the USAA Life Money Market Fund
("Money Market Fund"), USAA Life Income Fund ("Income Fund"), USAA Life Growth
and Income Fund ("Growth and Income Fund"), USAA Life World Growth Fund ("World
Growth Fund"), USAA Life Diversified Assets Fund ("Diversified Assets Fund"),
USAA Life  Aggressive Growth Fund ("Aggressive Growth Fund"), and USAA Life
International Fund ("International Fund"); the Capital Growth Portfolio-Class A
shares of the Scudder Variable Life Investment Fund (the "Scudder VLIF Capital
Growth Portfolio"); the Growth Portfolio of The Alger American Fund (the "Alger
American Growth Portfolio"); and the Equity 500 Index Fund, Small Cap Index Fund
and EAFE/R/ Equity Index Fund of the BT Insurance Funds Trust (the "BT Equity
500 Index Fund," "BT Small Cap Index Fund" and "BT EAFE/R/  Equity Index Fund").
The Equity 500 Index Fund, Small Cap Index Fund and EAFE/R/ Equity Index Fund of
the BT Insurance Funds Trust are not available to California residents as of the
date of this Prospectus, but are expected to be available in the near future.

  ACCUMULATION UNITS AND ANNUITY UNITS OF THE VARIABLE  FUND ACCOUNTS ARE  NOT
DEPOSITS OR OTHER OBLIGATIONS OF, OR GUARANTEED BY, THE USAA FEDERAL SAVINGS
BANK, ARE NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY
OTHER GOVERNMENT AGENCY,  ARE SUBJECT TO INVESTMENT RISKS, AND MAY LOSE VALUE.

  This Prospectus sets forth information about the Separate Account that a
potential investor ought to know before investing. Please read it carefully and
retain it for future reference. The Company has filed a Statement of Additional
Information, dated May 1, 1998 ("SAI"), about the Separate Account with the
Securities and Exchange Commission ("SEC" or the "Commission"). The SAI, dated
May 1, 1998, is incorporated by reference into this Prospectus and will be
provided on request and without charge. For a copy of the SAI or an Annual
Report, call 1-800-531-2923 or write the Company at the address above. A Table
of Contents for the SAI appears on page 36 A of this Prospectus.

 SECURITIES DESCRIBED IN THIS PROSPECTUS NOR HAS IT PASSED UPON THE ACCURACY OR
                          ADEQUACY OF THIS PROSPECTUS.

          ANY REPRESENTATION  TO THE  CONTRARY IS A CRIMINAL OFFENSE.

      NO  PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
 REPRESENTATIONS OTHER THAN THOSE CONTAINED IN THIS PROSPECTUS AND THE RELATED
STATEMENT OF ADDITIONAL INFORMATION  (OR ANY SALES LITERATURE APPROVED BY USAA
LIFE ) IN CONNECTION WITH THE OFFER CONTAINED IN THIS PROSPECTUS, AND, IF GIVEN

    BEEN AUTHORIZED. THE CONTRACTS ARE NOT AVAILABLE IN ALL STATES AND THIS
 PROSPECTUS DOES NOT CONSTITUTE AN OFFER IN ANY JURISDICTION TO ANY PERSON TO
 WHOM SUCH OFFER WOULD BE UNLAWFUL THEREIN. THIS PROSPECTUS IS VALID ONLY WHEN
ACCOMPANIED OR PRECEDED BY THE CURRENT PROSPECTUS OF USAA LIFE INVESTMENT TRUST,
THE SCUDDER VLIF CAPITAL GROWTH PORTFOLIO, THE ALGER AMERICAN GROWTH PORTFOLIO,
THE BT EQUITY 500 INDEX FUND,  THE BT SMALL CAP INDEX FUND, AND THE BT EAFE/R/
EQUITY FUND. EACH PROSPECTUS SHOULD BE READ CAREFULLY BEFORE INVESTING AND THEN

SUMMARY
- -------

  Set out below, in question and answer format, is a summary of the Contract.
Please read the remainder of this Prospectus for a more detailed description.
Variations due to requirements of particular states, if any, are described in
supplements which are attached to this Prospectus, or in endorsements to the
Contract, as appropriate.

WHAT TYPE OF CONTRACT AM I BUYING?

  You are buying a Contract that provides you with the ability to make flexible
premium payments that accumulate on a fixed or variable basis, and that you can
use to purchase either a Fixed and/or Variable Annuity. This Prospectus is
intended to provide disclosure primarily about the variable portion of the
Contract. (See "The Contracts," below.)

HOW MUCH MUST I PAY, AND HOW OFTEN?

  Subject to the minimum initial and subsequent premium requirements of $1,000
and $100, respectively, the amount and frequency of premium payments is
completely flexible. Lower minimums apply in the case of Qualified Plans and for
USAA Life employees. (See "Contract Issuance and Premium Payments," below.)
Except in the case of Qualified Plans, if your Contract Value falls below $1,000
and we have received no premium payments for two years, we may cancel your
Contract and return to you its remaining value (less any applicable charges).

WHAT IS THE SEPARATE ACCOUNT?
    
  The Separate Account is a segregated asset account of USAA Life established
under Texas insurance law and registered with the SEC as a unit investment
trust.  The Separate Account is divided into twelve Variable  Fund Accounts,
each of which invests in a corresponding Fund of one of the available Mutual
Funds. (See "The Separate Account," below.)

WHAT ARE MY INVESTMENT CHOICES?

  You may invest your premiums in the Fixed Fund Account and/or up to twelve
Variable Fund Accounts, each of which invests in a corresponding Fund of a
Mutual Fund.  The twelve Funds that are available through the Variable Fund
Accounts include the following:

                         BT EAFE/R/ Equity Index Fund

For more information, see "The Funds" below.

WHO MANAGES MY INVESTMENT?
  The investment advisers for the Trust, the Scudder VLIF Capital Growth
Portfolio, the Alger American Growth Portfolio, and the BT Funds, are USAA
Investment Management Company ("USAA IMCO"), Scudder Kemper Investments, Inc.
("Scudder"),  Fred Alger Management, Inc. ("Alger Management"), and Bankers
Trust Company ("Bankers Trust"), respectively (collectively, the "Advisers").
Each Adviser is registered as an investment adviser with the SEC. (See "The
Funds - Management of the Funds," below.)
     
HOW DOES THE CONTRACT WORK?
  Once your payment is received and your application is approved by the Company,
we will issue you a Contract. During the Accumulation Phase, you may earn either
a fixed rate of interest that we declare periodically (but not less than 3%) by
allocating your premium payments to the Fixed Fund Account, or you may seek a
variable investment return by allocating your premium payments to one or more of
the Variable Fund Accounts. (See "Contract Issuance and Premium Payments,"
"Accumulation Phase," and "Distribution Phase," below.) During the Distribution
Phase, you may elect to receive Fixed and/or Variable Annuity Payments,
commencing on the Annuity Date. Fixed Annuity


                                      8 A
<PAGE>
 
    
Payments are periodic payments from USAA Life, the amount of which is fixed and
guaranteed by USAA Life. The amount of these payments will depend on the
Distribution Option you select, the age, and, generally, the sex of the
Annuitant, and the amount of Contract Value you elect to apply to the Fixed
Annuity Distribution Option. Variable Annuity Payments are periodic payments
from USAA Life, which vary depending on the net investment return of the
Variable Fund Accounts you select in connection with the Variable Annuity
Distribution Option. The net investment return of the Variable Fund Accounts
will, in turn, depend primarily on the investment experience of the
corresponding Funds. (See "Distribution Phase - Distribution Options," below.)

WHAT CHARGES ARE ASSOCIATED WITH THE CONTRACT?
  Beginning one year from the Effective Date of your Contract, we will deduct a
Contract Maintenance Charge of $30 per year from your Contract Value for general
administrative expenses. Should you decide to fully or partially withdraw or
transfer amounts from the Fixed Fund Account that have not been on deposit there
for at least seven years, you may incur a charge of anywhere from 1% to 7%,
depending upon how many years those payments have been invested in the Fixed
Fund Account. In addition, USAA Life assesses a charge at an annual rate of
0.65% against the assets of the Separate Account for the mortality and expense
risks we assume under the Contract. We also assess an Administrative Charge at
an annual rate of 0.10% against the assets of the Separate Account. (See
"Charges and Deductions," below.)

  In addition to the Contract charges, each Fund pays a fee to its Adviser,
based upon Fund assets under management.  There are also other expenses
associated with the daily operation of the Funds. These are more fully described
in the Prospectus for each Fund.
     
  If your state assesses a premium tax with respect to your Contract, USAA Life
will deduct those amounts from the Contract Value in accordance with applicable
law. (See "Charges and Deductions," below.)

WHAT HAPPENS IF I DIE BEFORE THE ANNUITY DATE?
  If you are the Annuitant, then the Beneficiary whom you designate will receive
either the sum of all premium payments (minus any prior partial withdrawal) or
the present Contract Value, whichever is greater, less any applicable premium
tax charge. Your Beneficiary will have certain options for how the money is to
be paid out. If you are an Owner who is not also an Annuitant, certain special
rules apply. (See "Death Benefits - Death Benefit Prior to Annuity Date,"
below.)
    
MAY I TRANSFER CONTRACT VALUE AMONG VARIABLE FUND ACCOUNTS?
  Yes. However, there are limits on how often you may do so.  (See "Transfers
and Withdrawals" and "Distribution Phase - Transfers of Annuity Units," below.)

MAY I TRANSFER CONTRACT VALUE FROM THE FIXED FUND ACCOUNT TO THE VARIABLE  FUND
ACCOUNTS, AND VICE-VERSA?
  Yes, subject once again to specific restrictions in the Contract and the
Prospectus. You may incur a charge for transfers from the Fixed Fund Account.
(See "Transfers and Withdrawals," and "Charges and Deductions - Fixed Fund
Account Withdrawal Charge," below.)

MAY I FULLY WITHDRAW FROM THE CONTRACT OR MAKE A PARTIAL WITHDRAWAL?
  Yes, subject to any Contract requirements and to any restrictions imposed
under certain retirement plans. (For example, Owners under a public school
system or tax-exempt institution plan qualifying under Section 403(b) of the
Code are subject to special restrictions upon withdrawal.)  If you make a full
or partial withdrawal from the Contract, certain charges may be assessed. (See
"Charges and Deductions," below.) In addition, the Internal Revenue Service
("IRS") may assess a 10% premature withdrawal penalty tax if you are under 
59 1/2 years of age. (See "Transfers and Withdrawals" and "Tax Matters," below.)
     
ARE LOANS AVAILABLE UNDER THE CONTRACT?
  No. However, the Company may in the future permit loans in connection with
tax-sheltered annuity Contracts.  See "TSA Loans" in the SAI.
    
DO I GET A "FREE LOOK" AT THIS CONTRACT?
  Yes. If you return your Contract to the Company within the Free Look Period,
it will be cancelled.  (See "Return Privilege," below.) During the Free Look
Period plus five calendar days, your initial premium payment will be allocated
to the USAA Life  Money Market Fund Account (See "Initial Premium Payments,"
below.)
     
EXPENSE TABLE
- -------------

  The purpose of the Expense Table and the Example is to assist the Owner in
understanding the various costs and expenses that an Owner will bear directly or
indirectly when investing in the Contract.  The expenses of the Separate Account
as well as those of the Funds are reflected in the Table and the Example, but
premium taxes that are applicable in some states are not reflected.  For a more
complete description of the expenses of the Separate Account, see "Charges and
Deductions," below.  For more complete information regarding expenses paid out
of the assets of the Fund, see the Prospectuses for the Funds.

(1) A charge of up to 7% of amounts allocated to the Fixed Fund Account will be
    deducted upon certain transfers or withdrawals from that Account. (See
    "Charges and Deductions - Fixed Fund Account Withdrawal Charge," below.)
    
(2) Annual deduction of $30 applies only during the Accumulation Phase and will
    be waived to the extent it would cause the amount of interest earned on the
    Fixed Fund Account from the last Contract anniversary to be less than a 3%
    annual effective rate, or a higher rate if required by state law. (See
    "Charges and Deductions - Contract Maintenance Charge," below.)

(3) Applies to all twelve Variable Fund Accounts but not to the Fixed Fund
    Account.

(4) The Fund expenses shown above are assessed at the underlying Fund level and
    are not direct charges against the Separate Account assets or reductions
    from Contract Values and are not relevant to the Fixed Fund Account. These
    Fund expenses are taken into consideration in computing each Fund's Net
    Asset Value, which is the share price used to calculate the Variable Fund
    Account Values.

(5) Pursuant to an Underwriting and Administrative Service Agreement
    ("Underwriting Agreement") with the Trust, USAA Life, out of its General
    Account, has agreed to assume Trust Fund expenses to the extent that such
    expenses exceed, on an annual basis, .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. In the absence of expense reimbursement arrangements, the expenses of
    certain of the Trust's Funds for the 1997 fiscal year would have been as
    follows: .70%, .52%, .85% and 1.24% for the Money Market, Income,
    Diversified Assets, Aggressive Growth and International Funds, respectively.
    The Underwriting Agreement is terminable by any party thereto upon 120 days'
    notice to the other parties. Pursuant to a voluntary expense reimbursement
    arrangement, Bankers Trust reimburses the BT Funds for certain expenses so
    that the Equity 500 Index Fund, Small Cap Index Fund and EAFE/R/ Equity
    Index Fund total operating expenses will not exceed 0.30%, 0.45% and 0.65%
    respectively. Such expense reimbursements may be terminated at the
    discretion of Bankers Trust. Absent such voluntary reimbursement
    arrangement, the expenses for the 1997 fiscal year for the Equity 500 Index
    Fund, the Small Cap Index Fund and the EAFE/R/ Equity Index Fund would have
    been 2.78%, 3.27% and 2.75% respectively.

EXAMPLE:
    
  The following chart depicts the dollar amount of expenses that would be
incurred under this Contract assuming a $1,000 investment and 5% annual return,
assuming you invest solely in one of the Variable Fund Account options. These
dollar figures are illustrative only and should not be considered a
representation of past or future expenses. Actual expenses may be greater or
lesser than those shown below and would differ for amounts allocated to the
Fixed Fund Account. The expense amounts presented are derived from a formula
which expresses the $30 Contract Maintenance Charge as a percentage of an
estimated $32,325 average Contract account size.
     
  If you surrender your Contract or annuitize at the end of the applicable time
period, you would pay the following expenses on a $1,000 investment, assuming a
5% annual return on assets:

SELECTED ACCUMULATION UNIT DATA
- -------------------------------
    
  The table below reflects the historical performance of an accumulation unit
outstanding throughout the period shown under a representative Contract invested
in each Variable Fund Account, other than the Variable Fund Accounts
corresponding to the Funds of the BT Funds, which Fund Accounts had not yet
commenced operations. When reading the table, please bear in mind that the unit
value of each Variable Fund Account will not be the same on any given day as the
net asset value per share of the corresponding Fund in which that Subaccount
invests. One reason for this divergence is that each unit value consists of the
corresponding Fund's net asset value minus charges to the Variable Fund Account.
In addition, dividends declared by each corresponding Fund are reinvested by the
Variable Fund Account in additional shares of that Fund. These distributions
have the effect of reducing the value of each share of the Fund and increasing
the number of Fund shares outstanding. However, the total cash value in the
Variable Fund Account does not change as a result of such distribution. The
information in the table below is derived from the Separate Account's financial
statements, which have been audited by KPMG Peat Marwick LLP, the Separate
Account's certified independent public accountants, and should be read in
conjunction with the Separate Account's financial statements.

FINANCIAL STATEMENTS
- --------------------

  The financial statements for the Separate Account are located in its Annual
Report, and the financial statements for the Company are located in the SAI. See
the cover page of this Prospectus for information on how to obtain a copy of the
Annual Report or SAI. These financial statements have been included in reliance
on the reports thereon of KPMG Peat Marwick, LLP, and the firm's authority as
experts in accounting and auditing. The financial statements of the Company
should be considered only as bearing on the ability of the Company to meet its
contractual obligations under the Contracts; they do not bear on the investment
performance of the Separate Account.

USAA LIFE
- ---------
    
  USAA Life is a stock insurance company incorporated in the State of Texas in
1963. The Company is principally engaged in writing life insurance policies,
annuity contracts and health insurance policies. The Company is authorized to
transact insurance business in all states including the District of Columbia but
excluding New York. The Company on a consolidated statutory basis had total
assets of $6,862,829,054 on December 31, 1997. The Company is a wholly-owned
stock 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. The Home Office of USAA Life is 9800 Fredericksburg
Road, San Antonio, Texas 78288.
     
  As of the date of this Prospectus, USAA and USAA Life both held the highest
ratings from A.M. Best Company (A++ Superior) and Standard & Poor's Corporation
(AAA Superior). USAA and USAA Life also held the highest and second-highest
ratings (Aaa Exceptional and AA1 Excellent), respectively, from Moody's
Investors Service, as of that date. The ratings published by these independent
financial rating agencies serve as measurements of an insurer's financial
condition. The ratings are based on a qualitative as well as quantitative
evaluation of many factors, including an insurer's profitability, asset quality,
adequacy of reserves, capitalization and management practices. These ratings are
not a rating of investment performance that purchasers of insurance products
have experienced or are likely to experience in the future.

THE SEPARATE ACCOUNT
- --------------------

  The Separate Account was established under Texas law pursuant to a resolution
of the Board of Directors on February 8, 1994. The Separate Account is
registered with the SEC as a unit investment trust under the Investment Company
Act of 1940, as amended (the "1940 Act").  The assets of the Separate Account
are the property of the Company. However, the assets of the Separate Account not
in excess of the reserves, and other Contract liabilities with respect to the
Separate Account, are not 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, credited to or charged against
the Separate Account without regard to other income, gains or losses of the
Company. The Company's obligations arising under the Contracts are general
corporate obligations. The Separate Account is divided into twelve Variable Fund
Accounts, each of which invests in a corresponding Fund or Portfolio, described
below.

THE FUNDS
- ---------

THE VARIABLE  FUND ACCOUNTS
- ---------------------------
    
  Each of the twelve Fund Accounts of the Separate Account invests solely in a
corresponding Fund.  Seven of the Fund Accounts invest in Funds of the Trust;
one Fund Account invests in a Fund of the Scudder Fund; one Fund Account invests
in a Fund of the Alger Fund; and three Fund Accounts invest in Funds of the BT
Funds.  The Trust, the Scudder Fund, the Alger Fund and the BT Funds are all
Mutual Funds    


                                      12A

Adviser's mailing address is 9800 Fredericksburg Road, San Antonio, Texas 78288.
The Adviser is a wholly-owned indirect subsidiary of USAA. Scudder Kemper
Investments, Inc., Two International Place, Boston, Massachusetts 02110, serves
as the Adviser to the Scudder VLIF Capital Growth Portfolio. Fred Alger
Management, Inc., 75 Maiden Lane, New York, New York 10038, serves as the
investment manager of the Alger American Growth Portfolio. Bankers Trust
Company, 130 Liberty Street, New York, New York, 10006, serves as the investment
manager of the BT Funds.  Neither Scudder Kemper Investments, Inc., Fred Alger
Management, Inc., nor Bankers Trust Company is affiliated with USAA.
     
SUBSTITUTION OF FUNDS

  If the shares of any Fund should no longer be available for investment by the
Separate Account, or if in the judgment of the Company further investment in
such shares would be undesirable in view of the purposes of the Contracts, the
Company may eliminate such 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 and be subject to such requirements as it may
impose. In addition, the Company may add new Variable  Fund Accounts to permit
investment in additional mutual funds.

         

                                      13A
<PAGE>
 
         

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS
    
  Any dividends or capital gain distributions paid on Fund shares are
automatically reinvested in shares of the Fund from which they are received at
the Fund's net asset value on the date payable. Such dividends and distributions
will have the effect of reducing the net asset value of each share of the
corresponding Fund, other than the Money Market Fund, and increasing, by an
equivalent value, the number of shares outstanding of the Fund. However, the
value of your interest in the corresponding Variable Fund Account will not
change as a result of any such dividends and distributions.

VOTING PRIVILEGES

  Based upon its present view of applicable law, the Company will vote the
shares of the Trust, the Scudder VLIF Capital Growth Portfolio, the Alger
American Growth Portfolio, the BT Equity 500 Index Fund, the BT Small Cap Index
Fund and the BT EAFE/R/ Equity Index Fund held directly by it or through the
Separate Account in the Variable  Fund Accounts at annual or special meetings,
if any, of the shareholders of such Funds in accordance with instructions
received from persons having the voting interest in the corresponding Variable
Fund Accounts. The person having the voting interest in a Variable Fund Account
will be the Contract Owner. The persons entitled to give voting instructions and
the number of shares which a person has a right to vote will be determined based
on Variable Fund Account Values as of the record date of the meeting.

  The Company will vote shares attributable to Contracts for which it has not
received instructions, as well as shares attributable to it, in the same
proportion as it votes shares for which it has received instructions, unless it
determines that it may vote such shares in its own discretion. The Trust, the
Scudder Fund, the Alger Fund and the BT Funds do not hold regular shareholder
meetings.

SPECIAL CONSIDERATIONS

     The Scudder Fund, the Alger Fund, and the BT Funds offer shares to separate
accounts of unaffiliated life insurance companies to fund benefits under
variable annuity contracts and variable life insurance policies.  The Trust
offers its shares to separate accounts of the Company to fund benefits under the
Contracts and the variable life insurance policies.  The Company does not
foresee any disadvantage to Contract Owners arising out of these arrangements.
Nevertheless, differences in treatment under tax and other laws, as well as
other considerations, could cause the interests of various purchasers of
contracts and policies to conflict.  For example, violation of the federal tax
laws by one separate account investing in a Mutual Fund could cause the
contracts or policies funded through another separate account to lose their tax-
deferred status, unless remedial action were taken.  If a material
irreconcilable conflict arises between separate accounts, a separate account may
be required to withdraw its participation in a Mutual Fund.  If it becomes
necessary for any separate account to replace shares of a Mutual Fund with
another investment, the Mutual Fund may have to liquidate portfolio securities
on a disadvantageous basis.  At the same time, each Mutual Fund and the Company
are subject to conditions imposed by the Securities and Exchange Commission that
are designed to prevent or remedy any conflict of interest.  In this connection,
the Board of Trustees of each Mutual Fund has the obligation to monitor events
in order to identify any material irreconcilable conflict that may possibly
arise and to determine what action, if any, should be taken to remedy or
eliminate the conflict.

FIXED FUND ACCOUNT
- ------------------

  THE FIXED FUND ACCOUNT IS NOT AVAILABLE IN ALL STATES. IF YOU ARE A RESIDENT
OF MD, WA, OR, PA OR MA, THE FIXED FUND ACCOUNT IS NOT PART OF THE CONTRACT. THE
FIXED FUND ACCOUNT IS ALSO NOT PART OF THE CONTRACT ISSUED UNDER THE TEXAS
OPTIONAL RETIREMENT PROGRAM.  (SEE "TEXAS OPTIONAL RETIREMENT PROGRAM ("ORP").
AMOUNTS ALLOCATED TO THE FIXED FUND ACCOUNT OF THIS CONTRACT, AND AMOUNTS
SUPPORTING FIXED ANNUITY PAYMENTS, BECOME PART OF THE COMPANY'S GENERAL ACCOUNT.
BECAUSE OF EXEMPTIVE AND EXCLUSIONARY PROVISIONS, INTERESTS IN THE GENERAL
ACCOUNT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, NOR IS THE
GENERAL ACCOUNT REGISTERED AS AN INVESTMENT COMPANY UNDER THE 1940 ACT. THE
STAFF OF THE SECURITIES AND EXCHANGE COMMISSION HAS NOT REVIEWED THE DISCLOSURES
IN THIS PROSPECTUS THAT RELATE TO THE FIXED FUND ACCOUNT OR FIXED ANNUITY
PAYMENTS. DISCLOSURES REGARDING THESE MATTERS, HOWEVER, MAY BE SUBJECT TO
CERTAIN GENERALLY-APPLICABLE PROVISIONS OF THE FEDERAL SECURITIES LAWS RELATING
TO THE ACCURACY AND COMPLETENESS OF STATEMENTS IN PROSPECTUSES.
     
  Our obligations with respect to the Fixed Fund Account are legal obligations
of USAA Life and are supported by the assets of the General Account, which also
support obligations incurred by us under other insurance contracts. Investments
purchased with amounts allocated to the Fixed Fund Account are the property of
USAA Life, and Contract Owners have no legal rights in such investments.


                                      14A
<PAGE>
 
  Premium payments that you allocate, as well as amounts that you transfer, to
the Fixed Fund Account during any month ("New Money") will earn interest at the
New Money Interest Rate, which is the rate of interest that USAA Life declares
at the beginning of each month for all New Money received that month. The New
Money Interest Rate is credited through the end of the current calendar year in
which the New Money is allocated to the Fixed Fund Account.

  The Contract Value in your Fixed Fund Account that is not attributable to New
Money will earn interest at the Portfolio Interest Rate, which is the rate of
interest that USAA Life declares at the beginning of each calendar year for that
year. USAA Life also may declare, before the beginning of each month, additional
interest on all amounts in the Fixed Fund Account other than New Money.

  Both the New Money Interest Rate and the Portfolio Interest Rate are
guaranteed ("Guaranteed Interest Rates"). The Guaranteed Interest Rates under
the Contract 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 an Owner 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
previously applicable, for the remainder of the year in which the transfer
occurred. You should be aware, however, that because any amounts transferred in
the foregoing manner would be considered New Money, they would again become
subject to the Fixed Fund Account Withdrawal Charge. (See "The Fixed Fund
Account - Fixed Fund Account Withdrawal Charge," below.)
     
FIXED FUND ACCOUNT WITHDRAWAL CHARGE

  We will deduct a charge from certain premium payments or other payments
withdrawn or transferred from the Fixed Fund Account. In declaring interest
rates for the Fixed Fund Account, USAA Life takes numerous factors into account,
including the length of time that it expects Owners to leave funds in the Fixed
Fund Account. Generally speaking, a high degree of such 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 calculated as 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
applicable percentage will depend on how many years have elapsed since the
Payment being withdrawn or transferred was originally credited to the Fixed Fund
Account, according to the following schedule:


                     FIXED FUND ACCOUNT WITHDRAWAL CHARGE

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

THE FIXED FUND ACCOUNT WITHDRAWAL CHARGE DOES NOT APPLY TO THE VARIABLE FUND
ACCOUNTS.

  For purposes of determining the applicable charge, a year is considered to be
a period of 365 days unless a leap year is involved. In addition, Payments will
be considered to be withdrawn or transferred on a first in-first out ("FIFO")
basis, that is, the earliest Payments will be considered withdrawn first and
before any earnings are deemed to be withdrawn. The Fixed Fund Account
Withdrawal Charge is calculated separately for Payments that have been made into
the Fixed Fund Account. The calculation of the Fixed Fund Account Withdrawal
Charge will be made in accordance with applicable state law and may vary. Please
refer to your annuity contract for more information.

  The following transactions are not considered to be withdrawals for purposes
of assessing the Fixed Fund Account Withdrawal Charge: death of the Annuitant or
Owner prior to the Annuity Date, payment of a lump sum in lieu of a Distribution
Option and termination due to insufficient Contract Value. In addition, the
commencement of a Distribution Option currently is not subject to the Fixed Fund
Account Withdrawal Charge.


                                      15A
<PAGE>
 
THE FIXED FUND ACCOUNT WITHDRAWAL CHARGE WILL NOT APPLY:

 . To any Payment received by the Company 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 further Contract Years.

CONTRACT ISSUANCE AND PREMIUM PAYMENTS

ALLOCATION OF INITIAL AND SUBSEQUENT PREMIUM PAYMENTS
    
  You may allocate your premium payments among the Fixed and Variable Fund
Accounts under this Contract in amounts no smaller than one tenth of a percent,
provided that the total amount equals an aggregate of 100 percent.

INITIAL PREMIUM PAYMENTS

  If you allocate any part of the initial premium payment to the Fixed Fund
Account, we will allocate it to that Account on the Effective Date. If you
allocate any part of the initial premium payment to any of the Variable Fund
Accounts, we will allocate it to the USAA Life Money Market Fund Account on the
Effective Date. That premium will remain in the USAA Life Money Market Fund
Account for the Free Look Period plus five calendar days. On the Valuation Date
immediately following the end of that 
     


                                      16A
<PAGE>
 
period, the initial premium payment, together with any subsequent premium
payments that have been made, plus the earnings thereon will be allocated among
the Variable Fund Accounts as directed on the Application.

SUBSEQUENT PREMIUM PAYMENTS
    
  So long as your Contract Value does not fall below $1,000 (other than for
Contracts issued in connection with Qualified Plans), you need make no further
premium payments. You may, however, make subsequent premium payments at any time
before the Annuity Date. We will allocate subsequent premium payments among the
various Fixed and Variable  Fund Accounts in the same manner as the allocation
of the initial premium payment. We will credit all subsequent premium payments
on the Date of Receipt, using, in the case of Variable  Fund Accounts, the
Accumulation Unit Value next computed on the Date of Receipt. You may change the
allocation of subsequent premium payments at any time by sending a Written or
Telephone Request to our Service Office. A request to change subsequent premium
payment allocations will be effective with the first premium payment received on
or after the Date of Receipt of the request.

DISTRIBUTOR

  USAA IMCO, an affiliate of USAA Life, serves as the principal underwriter
("Distributor") of the Contracts pursuant to a Distribution and Administration
Agreement  ("Agreement"). Under the Agreement, USAA IMCO will offer the
Contracts for sale and distribution through 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.

RETURN PRIVILEGE

  You may return your Contract to the Company within the Free Look Period. If
you return your Contract within the Free Look Period, we will refund any premium
payment allocated to the Fixed Fund Account, plus the greater of (1) premium
payments allocated to the Variable Fund Accounts or (2) the Variable Fund
Accounts' Value as of the Date of Receipt of the cancellation request plus any
mortality and expense risk charge, administrative expense charge and any premium
taxes that have been deducted. The Contract will be deemed void as if no
Contract had been issued.

MINIMUM CONTRACT VALUE

  If during the Accumulation Phase your Contract Value is less than $1,000 and
we have received no premium payments for a period of two years, we may at our
option cancel your Contract. This minimum does not apply in the case of
Contracts issued in connection with Qualified Plans. We will give the Contract
Owner 30 days written notice of, and an opportunity to satisfy, this requirement
before we cancel the Contract. In the event of a cancellation, we will pay the
Owner the Contract Value in a lump sum and be released of any further
obligations under the Contract.

ACCUMULATION PHASE
- ------------------

  The Accumulation Phase of a Contract is the period prior to the Annuity Date
during which you may invest your premium payments in the Fixed and/or Variable
Fund Accounts under the Contract. All premium payments credited to the Fixed
Fund Account or Variable Fund Accounts are net of any applicable premium tax.
Your premium payments will help build Contract Value.

  Your Contract Value during the Accumulation Phase will equal the sum of your
Variable Fund Accounts' Value and your Fixed Fund Account Value, as discussed
below.

FIXED FUND ACCOUNT VALUE

  The value of your Contract in the Fixed Fund Account ("Fixed Fund Account
Value") on any given Valuation Date will be equal to the sum of premium payments
allocated to the Fixed Fund Account:  (1) less any applicable premium tax; (2)
plus accumulated interest; (3) plus any amounts transferred from the Variable
Fund Accounts to the Fixed Fund Account; (4) less the Fixed Fund Account portion
of any Contract Maintenance Charges; and (5) less any withdrawals or transfers
of value.

VARIABLE  FUND ACCOUNT VALUE

  The value of your Contract in each Variable Fund Account ("Variable Fund
Account Value") on any given Valuation Date will equal the product of the number
of Accumulation Units credited to that Account as of that Valuation Date
multiplied by the value of the Account's Accumulation Unit ("Accumulation Unit
Value") as of that date.  A Variable Fund Account's Accumulation Unit Value will
fluctuate and vary with the investment experience of the corresponding Fund.

  Accumulation Units are credited to a Variable Fund Account when you allocate
premium payments or transfer amounts from other Variable Fund Accounts or the
Fixed Fund Account to that particular Variable Fund Account. The number of
     

                                      17A
<PAGE>
 
    
Accumulation Units credited to a Variable Fund Account is determined by dividing
the premium or other amount being credited to the Account by the Accumulation
Unit Value for the Valuation Date as of which the premium or other amount is to
be credited. In similar fashion, Accumulation Units are cancelled and your value
in a Variable Fund Account is reduced by any amounts you have withdrawn or
transferred from that Account, and by the portion of the Contract Maintenance
Charge that is allocable to the Account.

  You may call our Service Office to receive a quotation of the daily
Accumulation Unit Values credited to your Contract. The Accumulation Unit Value
of each Variable Fund Account will be determined once each Valuation Date at the
close of trading of the New York Stock Exchange, currently 4:00 p.m. New York
time.

  Each Variable Fund Account's Accumulation Units are valued separately.
Initially, the Accumulation Unit Value of each Variable Fund Account was set at
$10, except for the Money Market Fund Account, which was set at $1. Thereafter,
the Accumulation Unit Value of a Variable 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 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;

     (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).

TRANSFERS AND WITHDRAWALS
- -------------------------

TRANSFERS

  Subject to the restrictions below, you may transfer your Contract Value among
the Fixed and Variable Fund Accounts. There is no charge for a transfer from a
Variable Fund Account; however, transfers from the Fixed Fund Account may be
subject to a substantial withdrawal charge. (See "The Fixed Fund Account
Withdrawal Charge," above.)  The following restrictions apply to all transfers.
     
(1)  Only six transfers may be made each Contract Year.

(2)  The minimum amount of value that may be transferred from one Account to
     another Account is $100, or, if less, the total remaining Account balance.

(3)  A 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.
    
(4)  A transfer will result in either the redemption or purchase of Accumulation
     Units, or both; the transfer will be processed effective at the
     Accumulation Unit Value next computed on the Date of Receipt of the
     transfer request.
     
(5)  We reserve the right at any time and without prior notice to terminate,
     suspend, or modify these transfer privileges.


                                      18A
<PAGE>
 
FULL AND PARTIAL WITHDRAWALS
    
  You may, at any time during the Accumulation Phase while the Annuitant is
still living, make a full or partial withdrawal from your Contract. A full or
partial withdrawal from a Variable Fund Account is not subject to any charge,
except that the full $30 Contract Maintenance Charge will be deducted upon a
full withdrawal of the Contract during a Contract Year. A full or partial
withdrawal from the Fixed Fund Account, however, may be subject to a substantial
withdrawal charge. (See "The Fixed Fund Account - Fixed Fund Account Withdrawal
Charge," above.) To make full or partial withdrawal from your Contract, you must
submit a Written or Telephone Request to our Service Office. In the case of a
partial withdrawal, you should specify the Fixed and/or Variable Fund Accounts
from which you wish the partial withdrawal to be made. If you do not specify the
Variable  Fund Accounts, the withdrawal will be taken pro rata from your
Contract Value in each Variable  Fund Account. In connection with a partial
withdrawal, the minimum amount that you may request for withdrawal from the
Fixed Fund Account or a Variable  Fund Account is $500, or, if less, the
remaining balance in the Account.
     
  Except as provided under "Postponement of Payments," below, within seven
calendar days of the Date of Receipt of your Written or Telephone Request for
full or partial withdrawal, we will pay you all or part of your Contract Value,
as appropriate, as of the Date of Receipt, less any applicable charges. We
reserve the right to defer the payment of a withdrawal from the Fixed Fund
Account for up to six months from the Date of Receipt of the Written or
Telephone Request at our Service Office.

  Certain premature withdrawals may be subject to federal income tax and
penalties. For a discussion of this and other tax implications, see "Tax
Matters," below. The Owner should seek the advice of a tax adviser prior to
making a withdrawal.

CHARGES AND DEDUCTIONS
- ----------------------

  Various charges and deductions are made from the Contract Values, the Separate
Account, and the Funds, as described below.

PREMIUM TAXES

  Premium taxes or other similar assessments imposed by states, municipalities
or other governmental entities will be charged against the Contracts. Premium
taxes currently imposed by certain states range from 0% to 3.5%. The Company
will deduct such charges from the Owner's Contract Value either when the premium
payment is received or from the amount applied to effect an annuity at the time
annuity payments commence, in accordance with applicable state law. The amount
of any premium tax charge will depend on your state of residence. No amount
charged for premium taxes is deductible by you for federal income tax purposes.

CONTRACT MAINTENANCE CHARGE
    
  Beginning on the first anniversary of the Effective Date, and each Contract
anniversary thereafter, we will deduct a charge of $30 from the Contract Value
for Contract maintenance. This charge will apply only while the Contract is in
the Accumulation Phase. We will pro-rate the charge among the Fixed and Variable
Fund Accounts under the Contract. If the Contract is surrendered for the total
Contract Value on a date other than a Contract anniversary date, the entire
Contract Maintenance Charge for that year will be deducted. This charge will not
be deducted from death benefit proceeds on the death of an Owner or Annuitant,
from a lump sum payment in lieu of annuitization, or upon termination due to
insufficient Contract Value.   The Contract Maintenance Charge is waived by the
Company for contracts issued under the Texas Optional Retirement Program.

ADMINISTRATIVE EXPENSE CHARGE

  The Company assesses 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, together with the Contract Maintenance Charge, is to
reimburse the Company for the expenses it incurs in the establishment 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 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 Owner servicing, and all accounting, valuation,
regulatory and reporting requirements. The Company does not intend to profit
from this charge, on average, over the period that the Contracts are in force.
This charge will be reduced to the extent that the amount of this charge is in
excess of that necessary to reimburse the Company for its administrative
expenses. Should this charge prove to be insufficient, the Company will not
increase this charge (or the Contract Maintenance Charge) and will bear the
loss.

  The investment advisers or other affiliates of the Alger Fund and the BT
Funds, respectively, certain Mutual Funds reimburse the Company for the cost of
administrative services provided to those Funds as investment options under the
Contracts.  Compensation is paid out of fee earnings, based on a percentage of
each of these Mutual Fund's average net assets attributable to a Contract.
     


                                      19A
<PAGE>
 
MORTALITY AND EXPENSE RISK CHARGE
    
  To compensate it for assuming mortality and expense risks under the Contracts,
the Company assesses 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. The mortality risks
assumed by the Company arise from its contractual obligation to make annuity
payments after the Annuity Date for the life of the Annuitant in accordance with
annuity rates guaranteed in the Contracts under distribution options that
involve life contingencies. USAA Life will also assume a mortality risk by its
contractual obligation to pay a death benefit upon the death of an Annuitant or
Contract Owner prior to the Distribution Phase. The expense risk assumed by the
Company 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.  The Mortality and Expense Risk
Charge is guaranteed by the Company and cannot be increased.
     
  If the Mortality and Expense Risk Charge is insufficient to cover the actual
costs associated with the Contracts, the loss will be borne by the Company.
Conversely, if the amount deducted proves more than sufficient, the excess will
be a profit to the Company.  The Company expects to profit from this charge.

INCOME TAXES
    
  The Company reserves 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

  The fees and expenses paid out of the assets of the Funds are described  in
detail in the accompanying prospectuses for the Funds.

TRANSFER FEE
    
  The Company does not charge a transfer fee for transfers among the Variable
Fund Accounts, or for transfers from a Variable Annuity Fund Account to the
Fixed Fund Account. Transfers from the Fixed Account to a Variable Fund Account,
however, may be subject to a withdrawal charge.  (See "Fixed Fund Account
Withdrawal Charge," above.)

FIXED FUND ACCOUNT WITHDRAWAL CHARGE

  This charge is described under "Fixed Fund Account - Fixed Fund Account
Withdrawal Charge."  THIS CHARGE DOES NOT APPLY TO THE VARIABLE FUND ACCOUNTS.

SPECIAL SERVICES
- ----------------

DOLLAR COST AVERAGING PROGRAM

  During the Accumulation Phase, you may take advantage of our dollar cost
averaging program ("Dollar Cost Averaging Program").  The Dollar Cost Averaging
Program enables you to make regular, approximately equal investments over time
in the Fixed Fund Account and/or one or more of the  Variable Fund Accounts, by
transferring a fixed dollar amount or a specified percentage at regular
intervals from one or more Variable Fund Accounts under the Contract. Transfers
from the Fixed Fund Account are not permitted in connection with the Dollar Cost
Averaging Program.

  To begin the Dollar Cost Averaging 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 may be transferred is $100, or, if less, the remaining value
of the Account. The transfers must be scheduled to occur over a period of at
least 12 months at monthly, quarterly, or semi-annual intervals, as you elect.
     
  You may select this Program by submitting a Written Request to our Service
Office or by Telephone Request. You may cancel your participation in this
Program in the same manner.

  Transfers under the Dollar Cost Averaging Program will be processed effective
at the Accumulation Unit Value at the end of the Valuation Period that includes
the date of transfer.  The transfers made under the Dollar Cost Averaging
Program do not count toward your limit of six transfers per Contract Year.


                                      20A
<PAGE>
 
  We reserve the right to suspend, terminate or modify the offering of the
Dollar Cost Averaging Program upon providing you written notice 30 days in
advance.  Should we suspend or terminate the Program, the suspension or
cancellation will not affect any Contract as to which the Dollar Cost Averaging
Program is already in effect.

SYSTEMATIC WITHDRAWAL PROGRAM
    
  You may participate in a systematic withdrawal program ("Systematic Withdrawal
Program"), under which you may elect to withdraw pre-set amounts on an annual,
semi-annual, quarterly, or monthly basis from the Fixed and/or Variable Fund
Accounts under your Contract.

  The minimum amount of Contract Value you must have to begin a Systematic
Withdrawal Program is $20,000.  The minimum amount that can be withdrawn from
the Fixed or a Variable Fund Account under this Program is $250, or, if less,
the remainder of the Account.  You may change the amount or frequency of the
systematic withdrawal once in each Contract Year by submitting a Written or
Telephone Request to our Service Office.
     
  Withdrawals will be processed effective at the Accumulation Unit Value at the
end of the Valuation Period that includes the date of withdrawal.  Withdrawals
may be made pro rata from all Accounts under the Contract or the Owner may
specify the Accounts from which the withdrawal will be made.

  You may select this Program by submitting a Written or Telephone Request to
our Service Office. You may cancel your participation in this Program in the
same manner.

  Systematic withdrawals from the Fixed Fund Account are subject to any Fixed
Fund Account Withdrawal Charge that would apply to any other Fixed Fund Account
withdrawal.  (See "The Fixed Fund Account - Fixed Fund Account Withdrawal
Charge.") We reserve the right to suspend, terminate or modify the offering of
this Program during the Accumulation Phase of the Contract upon providing you
written notice 30 days in advance.  Should we suspend or terminate this Program,
the suspension or cancellation will not affect any Contract as to which the
Systematic Withdrawal Program is already in effect.

  Systematic withdrawals may be subject to federal income tax and penalties.
(See "Tax Matters.") The Owner should seek the advice of a tax adviser prior to
selecting a Systematic Withdrawal Program.

  Currently, there is no charge for systematic withdrawals, but the Company
reserves the right to charge for this Program during the Accumulation Phase of
the Contract. The Company does not intend to profit from any such charge.

AUTOMATIC PAYMENT PLAN
    
  You may establish an automatic payment plan ("Automatic Payment Plan") by
completing the appropriate form. Call our Service Office to obtain the form and
instructions. The Automatic Payment Plan is a program under which you may elect
to pay a pre-set premium amount periodically from a checking or savings account.
Under this Plan you authorize us to withdraw the pre-set premium amount
automatically on a pre-determined periodic basis to invest in the Fixed Fund
Account and/or one or more of the Variable Fund Accounts.
     
DISTRIBUTION PHASE
- ------------------

  The Distribution Phase describes the period under the Contract during which
the Annuitant or other payee will receive annuity payments, based on amounts
accumulated under the Contract during the Accumulation Phase.  The Company will
make annuity payments pursuant to the distribution option ("Distribution
Option") selected by the Contract Owner, beginning on the Annuity Date,
described below, and will continue to make such payments for the period
specified in the Distribution Option selected.

ANNUITY DATE

  The Annuity Date is the date that the Contract Owner selected on the
Application. If this Contract is used as a Qualified Plan, the Annuity Date must
not be later than the date required by federal income tax law.  (See  "Tax
Matters.") If this Contract is used as a Nonqualified Plan, the Annuity Date may
not be later than the Annuitant's 95th birthday. The Annuity Date also must be
at least six months after the Effective Date, unless we choose to waive this
requirement. The Contract Owner may change the Annuity Date selected by
submitting a Written Request to our Service Office, which must be  received at
least 30 days prior to the Annuity Date.

APPLICATION OF CONTRACT VALUE

  We will apply your Contract Value as of the end of the Valuation Period
immediately preceding the tenth day before the Annuity Date to the Distribution
Option that you have selected.  You may apply your Contract Value to provide:
(a) Fixed Annuity Payments, (b) Variable Annuity Payments, (c) a combination of
Fixed and Variable Annuity Payments, or (d) systematic withdrawals.



                                      21A
<PAGE>
 
FIXED AND VARIABLE ANNUITY PAYMENTS
    
  A Fixed Annuity provides monthly payments in an amount guaranteed by the
Company for a specified period of time. A Variable Annuity is similar to a Fixed
Annuity, except that the amount of each payment is not guaranteed and will vary
in accordance with the net investment experience of the Variable Fund Account to
which all or part of the Contract Value has been applied.
     
  Examples of the minimum amount of the first monthly Fixed or Variable Annuity
Payment for each $1,000 of Contract Value applied to a Fixed or Variable
Distribution Option is shown for various ages in the appropriate Annuity Payment
Table in the Contract.
    
  The amount of each subsequent monthly Fixed Annuity Payment is fixed and
specified by the terms of the Distribution Option selected. The amount of each
subsequent Variable Annuity Payment will be equal to the product of (1) the
number of Annuity Units of the Variable Fund Accounts funding the Variable
Annuity Payment multiplied by (2) the values of those Annuity Units  ("Annuity
Unit Values").  The payments from each Variable Fund Account are then added to
determine the total Variable Annuity Payment to be made to the Annuitant.

NUMBER OF ANNUITY UNITS - The number of Annuity Units of each Variable Fund
Account under your Contract will depend on the amount of Contract Value that you
have allocated to each Variable Fund Account.  The Contract Value allocated to
each Variable Fund Account that is applied to provide Variable Annuity Payments
is converted to a number of Annuity Units for each Variable Fund Account by
dividing the amount of the first Variable Annuity Payment by the Annuity Unit
Value of the relevant Variable Fund Account as of the Valuation Period ending
immediately prior to the tenth day before the Annuity Date. This results in a
number of Annuity Units for each Variable Fund Account which thereafter remains
constant.

ANNUITY UNIT VALUE - The Annuity Unit Value for each Variable  Fund Account was
established initially at $10 ($1 in the case of Money Market Fund Account).
Thereafter, the Annuity Unit Value of a Variable Fund Account of the end of any
Valuation Period is calculated by multiplying (1) by (2) and multiplying the
result by (3) where:

(1) is the Annuity Unit Value for the Variable Fund Account as of the end of the
    immediately preceding Valuation Period;
     
(2) is the Net Investment Factor for the Valuation Period then ended (see
    "Accumulation Phase - Net Investment Factor); and
    
(3) is a factor used to adjust for the assumed interest rate of 3% per year used
    in the annuity payment tables used in the Contracts (but which is not
    applicable because the actual amount earned on the Variable Fund Account is
    credited instead).

  As a result of the foregoing computations, if the net investment return for a
Variable Fund Account for any month is at an annual rate of more than 3%, any
Variable Annuity Payment based on that Variable Fund Account will be greater
than the Variable Annuity Payment based on that Account for the previous month.
Conversely, if the net investment return for a Variable Fund Account for any
month is at an annual rate of less than 3%, any Variable Annuity Payment based
on that Variable Fund Account will be less than the Variable Annuity Payment
based on that Account  for the previous month.
     
DISTRIBUTION OPTIONS

  You may elect to receive annuity payments under any one or more of the
Distribution Options listed below or any other option including a lump sum which
you and the Company mutually agree upon in writing. The Company may, at its
discretion, offer more favorable distribution option values based upon future
interest rate and mortality assumptions.
    
  At least 30 days prior to the Annuity Date, you must inform us in writing
which one of the Distribution Options you want to use to begin annuity payments,
and whether you want your Contract Value to fund a Fixed Annuity, a Variable
Annuity, a combination Fixed and Variable Annuity, or systematic withdrawals.
Your Contract Value will then be applied to determine the amount of the annuity
payment. Variable Annuity Payments can be provided from a maximum of four
Variable Fund Accounts.
     

  Payments on a Fixed Annuity basis are available under Options 1 through 5.
Payments on a Variable Annuity basis are available only under Options 1, 2 and
3. Option 6 provides for systematic withdrawals. You should be aware that,
although 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 Funds you select is poor, the amount of future
Annuity Payments could be reduced substantially or possibly altogether.

  No full or partial withdrawals are permitted under Options 1 through 5
subsequent to the Annuity Date.
    
  If you have not elected a Distribution Option at least 30 days prior to the
Annuity Date, we will apply the Contract Value, less any applicable premium tax
charge, under Distribution Option 2, with monthly payments guaranteed for 10
years. Fixed Fund Account Value will be applied to effect a Fixed Annuity.
Variable Fund Account Value will be applied to effect a Variable Annuity with
payments funded 
     


                                      22A
<PAGE>
 
    
from each Variable Fund Account in the same proportion as each Account's value
has to the total value of all Variable Fund Accounts under your Contract. We
will apply your Contract Value as of the end of the Valuation Period immediately
preceding the tenth day before the Annuity Date.    

  If the Contract has been assigned, the amount due the assignee must be paid in
a lump sum before any annuity payments can be determined and commence.

OPTION 1. INCOME PAYMENTS FOR LIFE - Under this option, the Company guarantees
periodic payments as long as the Annuitant is alive. It is possible under this
option for the Annuitant or other payee to receive only one annuity payment if
the Annuitant died prior to the second annuity payment, since no minimum number
of payments is guaranteed.

OPTION 2. INCOME PAYMENTS FOR LIFE WITH A CERTAIN PERIOD GUARANTEED - Under this
option, the Company guarantees that payments will be made for a certain period
of time even if the Annuitant dies before that period of time has expired.

OPTION 3. JOINT AND SURVIVOR LIFE INCOME - Under this option, the Company
guarantees periodic payments as long as the Annuitant or the Joint Annuitant is
alive. It is possible under this option for an Annuitant or other payee to
receive only one annuity payment if both Annuitants die prior to the second
annuity payment, since no minimum number of payments is guaranteed. If one of
these persons dies before the Annuity Date, the election of this option is
revoked, and the survivor becomes the sole Annuitant. The surviving Annuitant
may elect to receive any one or more of the other Distribution Options available
under the Contracts.

OPTION 4. INCOME FOR SPECIFIED PERIOD - If this option is selected, the Company
will make periodic payments which are guaranteed for a specified period of time.
This period of time is agreed upon before payments begin.  This period of time
cannot be longer than 30 years. The amount of each payment is the same and is
established pursuant to an annuity payment table contained in the Contract.

OPTION 5. INCOME OF FIXED AMOUNT - If this option is selected, a sum of monetary
value is transferred to the Company. In exchange, the Company agrees, 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 as long as the principal and interest earnings
last.

OPTION 6. SYSTEMATIC WITHDRAWALS - You may elect a series of substantially equal
periodic payments made either monthly, quarterly, semi-annually or annually.
These payments may be made over the life expectancy of the Annuitant or over a
shorter period of time.  You may change the amount or frequency of the
systematic withdrawal once in each Contract Year. The minimum amount of Contract
Value you must have to elect systematic withdrawal is $20,000 or $5,000 if the
Contract funds a Qualified Plan. The minimum amount that can be withdrawn from
an Account under this Contract is $250, or, if less, the remaining balance of
the Account. To the extent that this Option 6 is selected, the systematic
withdrawals are subject to the terms and conditions set forth under "Special
Services - Systematic Withdrawal Program," above.

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

  Once annuity payments have begun, a distribution option may be commuted only
if agreed to by the Company.

TRANSFERS OF ANNUITY UNITS
    
  After the Annuity Date, 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 may not be made from a Fixed Annuity to a Variable Annuity or to a new
Distribution Option. The minimum amount that may be transferred from a Variable
Fund Account is $100.

  Transfers from a Variable Fund Account to another Variable Fund Account or to
a Fixed Annuity are subject to a limit of three per Contract Year during the
Distribution Phase. There is no charge for such transfers. Once you have
transferred Annuity Unit Value to the Fixed Fund Account, it is locked in and
cannot be transferred out.
     
  We will process transfer requests using the Annuity Unit Value next computed
on the Date of Receipt of the transfer request, which may be by Written or
Telephone Request.

MINIMUM CONTRACT VALUE

  If at the time your Contract becomes payable, the Contract Value is less than
$2,000 or would provide a monthly distribution payment of less than $20 per
month, we may at our option cancel this Contract.  In this event, we will pay
the Annuitant the Contract Value in a lump sum and be released of any further
obligations under the Contract.

POSTPONEMENT OF PAYMENTS
- ------------------------
   
  We will normally pay amounts withdrawn from a Contract within seven calendar
days after our Date of Receipt of the Written or Telephone Request for
withdrawal using the Fixed or Variable Fund Account Value as of that Date of
Receipt. In addition, we will normally effect transfers of Contract Value among
the Fixed and Variable Fund Accounts using the Fixed or Variable Fund Account
Values as of the Date of Receipt of the Written or Telephone Request for
transfer.    

  However, we may not be able to determine the value of assets of the Variable
Fund Accounts if: (1) the New York Stock Exchange is closed for other than
customary weekends and holidays; (2) trading on the New York Stock Exchange is
restricted; or (3) an emergency exists as a result of which 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 may also postpone payments or defer such other
transactions where the SEC, by order, permits us  to do so for the protection of
Contract Owners. In addition, requests for full or partial withdrawals that
would be derived from a premium payment made to us by a check that has not
cleared the banking system will be deferred, to the extent permitted by
applicable law at the time, until payment of the check has been honored.

DEATH BENEFITS
- --------------

DEATH BENEFITS PRIOR TO THE ANNUITY DATE

  If the Annuitant is the Owner and dies before the Annuity Date, we will pay
the death benefit to the Beneficiary. If the Owner is not the Annuitant and the
Owner dies before the Annuity Date, we will pay a death benefit to the
Annuitant, or the Beneficiary if the Annuitant does not survive the Owner. We
must receive Proof of Death and a Written Request specifying the manner of
payment before the death benefit will be paid.

  The death benefit is the greater of: (1) the Contract Value on the Date of
Receipt of Proof of Death and any necessary instructions as to any Distribution
Option chosen; or (2) the sum of the premium payments credited to the Contract,
less the amount of any withdrawals and less any applicable premium tax.

  In lieu of receiving the death benefit in a lump sum, the Beneficiary or the
Annuitant, if entitled, may choose a Distribution Option.

  In accordance with current federal income tax law, if the Owner dies before
the Annuity Date, distribution of the Contract Value is required to be as
follows.
   
(1) If the Owner and Annuitant are the same person and no Beneficiary was
    designated or survived the Owner, full distribution to the Owner's estate
    must occur within five years after the Owner's death.

(2) If the Owner and the Annuitant are the same person and the Beneficiary is
    the Owner's spouse, or if the Owner and the Annuitant are not the same
    person and the Annuitant is the Owner's spouse, the spouse may: (a) assume
    ownership as the Annuitant and defer distribution until the Annuity Date, or
    (b) receive distributions over a period of time not exceeding the surviving
    spouse's life or life expectancy, in which case payments must begin within
    one year after the Owner's death.

(3) If the Owner and the Annuitant are the same person and the Beneficiary is
    not the Owner's spouse, then distribution must begin within one year after
    the Owner's 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 the Owner's death.

(4) If the Owner and the Annuitant are not the same person and the Annuitant is
    not the Owner's spouse, then distribution must begin within one year after
    the Owner's 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 the Owner, or, in the alternative, full distribution must
    occur within five years after the Owner's death.    

  Federal income tax law imposes similar requirements for distributions
following the death of an Owner of a Contract used as part of a Qualified Plan.

DEATH BENEFITS ON OR AFTER THE ANNUITY DATE

  In accordance with current federal income tax law, if the Owner is the
Annuitant and dies on or after the Annuity Date, any payment that remains under
the terms of the Contract must continue at least as rapidly as before the
Annuitant's death. To the extent that the Distribution Option then in effect
provides for any benefits following the Annuitant's death, the Beneficiary may:
   
(1) Continue to receive the same payments as the Annuitant; or    

                                      24A
<PAGE>
 
   
(2) If permitted under the Distribution Option in effect, receive higher
    payments, but over a shorter period of time, than the Annuitant was
    receiving; or

(3) If permitted under the Distribution Option in effect, take full distribution
    of the remaining value at the Annuitant's death.    

OTHER ASPECTS OF THE CONTRACT
- -----------------------------

CONTRACT AGREEMENT

  The Contract and the Application form the entire agreement between you and the
Company. We will consider statements in the Application to be representations
and not warranties. Only an officer of the Company has authority to: (1) waive a
provision of the Contract or (2) agree with the Owner to changes in the
Contract; and then only in writing.

  We reserve the right to change the Contract in order to comply with all
federal and state laws that apply to variable annuity contracts. This right
shall include, but not be limited to, the right to 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 thereunder.

CONTRACT OWNER

  The rights and privileges of the Contract belong to the Owner during the
Annuitant's lifetime. The Owner is the Annuitant unless the Application
designates a different Owner and we have approved. If the 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 Owner and dies, then the rights and privileges of ownership
will vest in the Beneficiary.

CHANGE OF OWNERSHIP AND ASSIGNMENT

  You may transfer or assign ownership of the Contract, subject to legal
restrictions. A request to transfer or assign ownership must be made in writing
and be sent to our Service Office. An assignment is not effective until it is
received by our Service Office. We are not responsible for determining the
validity of an assignment.

ANNUITANT

  The Annuitant must be a natural person.  The maximum age of the Annuitant on
the Annuity Date is age 95. The Owner, by Written Request, may change the
Annuitant at any time so long as such request is received by our  Service Office
at least 15 days prior to the Annuity Date.  The change will be effective as of
the Date of Receipt of the Written Request.  If an Annuitant  who is not the
Owner predeceases the Owner prior to the Annuity Date, then  the Beneficiary
becomes the Annuitant, unless the Owner by Written Request  designates another
Annuitant. A Non-Owner Annuitant 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
selected 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 are provided upon the Owner's or
the 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, any remaining payments
due will be paid to the Beneficiary's estate.

  Unless otherwise provided, benefits will be paid as follows:
   
(1) If two or more Beneficiaries have been named, all benefits will be paid in
    equal shares to those living at the time of the Annuitant's death; and

(2) If no Beneficiary survives the Annuitant, payment will be made to the
    Annuitant's estate.    

CHANGE OF BENEFICIARY

  The Owner, during the Annuitant's life, may change the Beneficiary.  To make a
change, written notice must be received by our Service Office.  The change will
take effect as of the date the Owner signs the request.  If we make any payments
before receiving the request to change the Beneficiary, we will receive credit
against our obligations under the Contract.

TAX MATTERS
- -----------
   
  The following is a brief summary of the federal income tax consequences of the
Contract. State and local income tax considerations, as well as estate tax, gift
tax, and inheritance tax considerations may also be material. The United States
Congress has in the past and may again in the future enact legislation changing
the tax treatment of annuities in both Qualified Plans and Nonqualified Plan.
The Treasury Department may issue new or amended regulations or other
interpretations of existing law.  Judicial interpretations may also affect the
tax treatment of annuities.  It is possible that such changes could have
retroactive effect. This discussion is not intended as tax advice. We recommend
that you consult with a professional adviser for your particular tax situation.
    

TAX CONSIDERATIONS RELATING TO YOUR ANNUITY

  Section 72 of the Internal Revenue Code of 1986, as amended ("Code") governs
the federal income taxation of annuities in general. Taxation of an annuity is
largely dependent upon:  (a) whether it is used in a retirement program eligible
for special tax treatment under the Code, referred to as Qualified Plans; and
(b) the status of the beneficial owner as either a natural or non-natural person
when the annuity is used in connection with a Nonqualified Plan.

NATURAL PERSONS

  Natural persons are individuals. Increases in the Contract Value of an annuity
when the Owner is a natural person generally are not taxed until a distribution
occurs.  Full or partial withdrawals and death benefit payments are examples of
distributions during the Accumulation Phase, and annuity payments and lump sum
distributions are examples of distributions during the Distribution Phase.
Certain other transactions may also be deemed to be a distribution, e.g., loans
and assignments.  The provisions of Section 72 of the Code concerning these
distributions are summarized briefly below.


NON-NATURAL PERSONS

  Non-natural persons include corporations, trusts and partnerships. Any
increase during a tax year in the Contract Value of an annuity which is not used
in a Qualified Plan eligible for special treatment under the Code is currently
includible in the gross income of a non-natural person that is the Owner. There
are exceptions to this rule if an annuity is held by:  (a) a structured
settlement company; (b) an employer with respect to a terminated pension plan;
(c) the estate of a decedent by reason of the death of the decedent; or (d)
certain entities other than employers, such as a trust holding an annuity as an
agent for a natural person.

DISTRIBUTIONS DURING THE ACCUMULATION PHASE FROM NONQUALIFIED PLANS

  Distributions received during the Accumulation Phase are treated as being
derived first from "income on the Contract" and includible in gross income. The
amounts of the distribution exceeding income on the Contract are referred to as
"investment in the Contract" and are not included in gross income. Income on the
Contract for an annuity would be income earned on previous premium payments.
Investment in the Contract is an amount equal to total premium payments paid for
any annuity contract, less any previous distributions from such annuity Contract
that were not included in gross income.

DISTRIBUTIONS DURING THE DISTRIBUTION PHASE FROM NONQUALIFIED PLANS

  The non-taxable portion of each annuity payment is determined by multiplying
each annuity payment by the ratio that the investment in the Contract bears to
(1) in the case of Fixed Annuity Payments, the total value of expected payments
under the Contract, and (2) in the case of Variable Annuity Payments, the total
number of annuity payments expected to be made for the term of the Distribution
Phase. The balance of each payment is the taxable portion. The taxable portion,
which is the income on the Contract, is taxed at ordinary income rates. Owners,
Annuitants, and Beneficiaries under the Contracts should seek competent
financial advice about the tax consequences of any distribution.

DISTRIBUTIONS FROM QUALIFIED PLANS

  Generally, if the employee does not have any cost basis for his or her
interest in the Qualified Plan, each payment, regardless of the amount, is fully
taxable as ordinary income, from both a fixed and variable annuity.  An
employee's cost basis in a Qualified Plan consists of any non-deductible
contributions he or she has made to the Qualified Plan and any employer's
contributions that have been taxed to him or her. When the employee has a cost
basis for his or her interest in the Qualified Plan and the variable annuity
starting date is after June 30, 1986, the payments are taxed under the annuity
rules as they are expressly applied to variable payments. Thus, the amount
excludable from the employee's gross income each year is determined by dividing
his or her cost basis (adjusted for any refund or period-certain guaranteed) by
the number of years in the payment period. If the annuity is payable for a life
or lives, the payment period is determined by the use of IRS annuity tables. The
computation for determining the amount excludable from the employee's gross
income is very complex and the advice of competent tax counsel is highly
recommended.

                                      26A
<PAGE>
 
PENALTY ON DISTRIBUTIONS

  Subject to certain exceptions, any distributions either during the
Accumulation or Distribution Phase from Nonqualified Plans are subject to a
penalty equal to 10% of the amount includible in gross income. This penalty is
not applied to certain distributions, including:  (a) distributions made on or
after the taxpayer's age 59 1/2 (b) distributions made on or after the death of
the Owner of the Contract, or where the Owner of the Contract is not a natural
person, the death of the Annuitant; (c) distributions attributable to the
taxpayer becoming disabled; (d) distributions which are part of a scheduled
series of substantially equal periodic payments made at least annually for the
life (or life expectancy) of the taxpayer or the joint lives (or life
expectancies) of the taxpayer and the taxpayer's Beneficiary; (e) distributions
of amounts that are allocable to investments in the contract  made prior to
August 14, 1982, and (f) payments under an immediate annuity as defined under
Section 72(u)(4) of the Code. Distributions from Qualified Plans are subject to
a similar 10% penalty with similar exceptions.  These exceptions include
distributions not in excess of deductible medical expenses and, after December
31, 1996, distributions to eligible unemployed persons not in excess of
deductible health insurance premiums.

  Any modification, other than by reason of death or disability, of
distributions that is part of a scheduled series of substantially equal periodic
payments as noted in (d) above, that occurred before the taxpayer's age 59 1/2
or within 5 years of the first of such scheduled payments, will result in
requirements to pay the penalties that would have been due had (d) above not
applied, plus interest for the deferral period. It is our understanding that the
IRS does not consider a scheduled series of distributions to qualify under (d)
above, if (as in the case of our Systematic Withdrawal Program) the owner of the
annuity retains the right to modify such distributions at will, even if such
right is not exercised.

MULTIPLE CONTRACTS

  Multiple contracts ("MCs") mean Nonqualified Plan annuity contracts that are
issued within the same calendar year to the same owner by one company or its
affiliates. MCs are treated as a single annuity contract for purposes of
determining the tax consequences of any distribution during the Accumulation
Phase. Such treatment may result in adverse tax consequences, including more
rapid taxation of the distributable amounts from the MCs.

FEDERAL INCOME TAX WITHHOLDING

  Section 3405 of the Code provides for federal income tax withholding on  the
portion of a distribution which is includible in the gross income of the
recipient. Amounts to be withheld depend upon the nature of the distribution.
However, a recipient may elect not to have income taxes withheld or have income
taxes withheld at a different rate by filing a completed election form with the
Company.

  Effective January 1, 1993, certain distributions from Qualified Plans under
Section 401 or Section 403(b) of the Code, which are not directly rolled over or
transferred to another eligible Qualified Plan, are subject to a mandatory 20%
withholding for federal income tax. The 20% withholding requirement does not
apply to:  (a) distributions for the life or life expectancy of the participant,
or joint and last survivor expectancy of the participant and a designated
beneficiary; (b) distributions for a specified period of ten years or more; or
(c) distributions which are required as minimum distributions.

ASSIGNMENTS

  Any Assignment of all or any portion of the Contract Value before the Annuity
Date is treated as a distribution subject to taxation under the distribution
rules set forth above. Any gain in the Contract Value subsequent to the
assignment while such assignment remains in effect is treated as income on the
Contract in the year in which it is earned.

TAX-FREE EXCHANGES

  Section 1035 of the Code provides that no gain or loss will be recognized on
the exchange of an annuity contract for an annuity contract.  This Section
applies only if the annuity contracts exchanged relate to the same owner. A
variable annuity contract is included within the meaning of an annuity contract
under this section of the Code. An owner who makes a fully tax-free exchange of
annuity contracts has the same basis in the new annuity contract as in the old
annuity contract.

TRANSFERS BETWEEN INVESTMENT OPTIONS

  Currently, transfers between investment options are not subject to federal
income taxation.

                                      27A
<PAGE>
 
GENERATION-SKIPPING TRANSFERS

  Under Section 2601 of the Code, certain taxes may be due when all or part of
an annuity is transferred to, or a death benefit is paid to, an individual two
or more generations younger than the owner.  These taxes tend to apply to
transfers of significantly large dollar amounts. We may be required to determine
whether a transaction must be treated as a "direct skip" as defined in the Code
and the amount of the resulting tax.  If required, we will deduct from your
Contract, or from any applicable payment to be treated as a direct skip, any
amount we are required to pay as a result of the transaction.

DIVERSIFICATION

  Section 817(h) of the Code imposes certain diversification standards on the
underlying assets of the Contracts. The Code provides that a Nonqualified Plan
variable annuity contract will not be treated as an annuity contract for any
period (and any subsequent period) for which the investments are not adequately
diversified in accordance with regulations prescribed by the United States
Treasury Department ("Treasury Department").  Disqualification of the Contract
as an annuity contract would result in imposition of federal income tax to the
Owner with respect to the income on the Contract prior to the receipt of
payments under the Contract. The Code contains a safe harbor provision which
provides that annuity contracts meet the diversification requirements if, as of
the end of each quarter, the underlying assets meet diversification standards
for a regulated investment company and no more than 55% of the total assets
consist of cash, cash items, U.S. government securities and securities of other
regulated investment companies.

     Treasury Regulation 1.817-5, which established diversification requirements
for the investment funds underlying variable contracts, amplifies the
diversification requirements for variable contracts set forth in the Code and
provides an alternative to the safe harbor provision described above. Under the
regulation, an investment fund will be deemed adequately diversified if: (a) no
more than 55% of the value of the total assets of the fund is represented by any
one investment; (b) no more than 70% of the value of the total assets of the
Fund is represented by any two investments; (c) no more than 80% of the value of
the total assets of the Fund is represented by any three investments; and (d) no
more than 90% of the value of the total assets of the Fund is represented by any
four investments.  This test must be met on the last day of each calendar
quarter or within 30 days thereafter.

  The Code provides that, for purposes of determining whether or not
diversification standards imposed on the underlying funds of variable contracts
by Section 817(h) of the Code have been met, each United States government
agency or instrumentality shall be treated as a separate issuer.
   
  The Company intends that all Funds of the Trust underlying the Contracts will
be managed by their Adviser in such a manner as to comply with these
diversification requirements. The Advisers to the Scudder Fund, the Alger Fund
and the BT Funds have agreed that those Funds also be managed to comply.    

CONTRACT OWNER CONTROL
   
  The Treasury Department has indicated that it may issue guidelines under which
a variable annuity contract will not be treated as an annuity contract for tax
purposes if the Owner of the Contract has excessive control over the investment
funds underlying the Contract.  As of the date of this Prospectus, no such
guidelines have been issued, although the Treasury Department has informally
indicated that any such guidelines could limit the number of investment funds or
the frequency of transfers among such funds.  The issuance of such guidelines
may require the Company to impose limitations on the Owner's right to control
the investment.   Such guidelines  may apply only prospectively, although
retroactive application is possible if such guidelines are considered not to
embody a new position.    

QUALIFIED PLANS

  There are various types of Qualified Plans for which the Contract may be
suitable. Owners, Annuitants and Beneficiaries are cautioned that benefits under
a Qualified Plan may be subject to the terms and conditions of the Qualified
Plan, or of provisions of law applicable to Qualified Plans, regardless of the
terms and conditions of the Contracts issued pursuant to the Qualified Plan.
Set out below is a general description of the types of Qualified Plans with
which the Contracts may be used.  Such descriptions are not exhaustive and are
for general informational purposes only.  The tax rules regarding Qualified
Plans are very complex and will have different applications, depending on
individual facts and circumstances.  Before purchasing a Contract for use in
funding a Qualified Plan, you should obtain competent tax advice, both as to the
tax treatment and suitability of such an investment.  Optional annuity benefits
provided under an employer's Qualified Plan may not, under Title VII of the
Civil Rights Act of 1964, vary between men and women.  The Contracts sold by the
Company in connection with employer sponsored Qualified Plans will utilize
annuity tables which do not differentiate on the basis of sex.

TYPES OF QUALIFIED RETIREMENT PLANS
- -----------------------------------

INDIVIDUAL RETIREMENT ANNUITY ("IRA")

  Individuals who are eligible may maintain an IRA. Subject to limitations,
contribution of certain amounts up to $2,000 for an employed individual may be
deductible from gross income. Purchasers of IRAs are to receive a special
disclosure document, which describes in detail the limitations on eligibility,
contributions, transferability and distributions.  It also describes the
conditions under which distributions from IRAs and other Qualified Plans may be
rolled over or transferred into an IRA on a tax-deferred basis.
   
ROTH IRA

  Individuals who are eligible may maintain a Roth IRA.  Contributions to a Roth
IRA are not tax deductible.  However, distributions from a Roth IRA may be tax
free depending on how and when the taxpayer withdraws the money from the Roth
IRA account.  Subject to certain income limitations, an individual may make a
rollover contribution from a non-Roth IRA to a Roth IRA.  While a rollover
contribution will be taxable currently, any future distributions from a Roth IRA
may be tax free.  The maximum non-deductible contribution to a Roth IRA is
$2,000, not counting rollover contributions.  Contributions to a Roth IRA may be
made beyond age 70  1/2.  The maximum yearly contributions allowed for any
individual to all Roth IRAs and IRAs set forth in the preceding paragraph is
$2,000.    

SIMPLIFIED EMPLOYEE PENSION-INDIVIDUAL RETIREMENT ANNUITY ("SEP-IRA")

  A SEP-IRA is a type of tax-deductible retirement plan, available to both
incorporated and unincorporated businesses. Ease of administration, a
characteristic not normally associated with qualified retirement plans, sets the
SEP-IRA apart. The SEP-IRA also offers most of the same tax incentives available
through a traditional pension or profit-sharing plan.  With a SEP-IRA, each plan
participant establishes an IRA. The employer puts the plan into effect by
completing IRS Form 5305-SEP and makes tax-deductible payments to each
participant's IRA. Currently, the maximum SEP-IRA payment on behalf of any one
employee in a calendar year is 15% of the employee's compensation, or $22,500,
whichever is less. The SEP-IRA is suited for a small business because it is a
simple, economical plan for both the employer and employees.

SALARY REDUCTION SIMPLIFIED EMPLOYEE PENSION-INDIVIDUAL RETIREMENT ANNUITY
("SARSEP-IRA")

  A SARSEP-IRA is a tax-deductible retirement plan designed to encourage small
companies and their employees to begin planning for their retirement.  It offers
the same tax incentives available through a regular SEP-IRA plan, pension and
profit sharing plans. While SEP-IRA plans allow only employer contributions,
SARSEP-IRA plans also allow voluntary contributions by employees through a
salary reduction plan.

  Beginning 1997, employers may no longer establish a new SARSEP-IRA.  However,
under pre-1997 rules, employers may continue to make contributions to SARSEP-
IRAs established before 1997, and SARSEP-IRAs may continue to invest their funds
with USAA Life, including the transfer of existing SARSEP-IRA funds to USAA
Life. In addition, employees hired after December 31, 1996, may participate in
SARSEP-IRAs established by their employers before 1997, if otherwise eligible
under existing SARSEP-IRA rules.

SIMPLE RETIREMENT ACCOUNTS

  Employees and employers may establish an IRA plan known as a simple retirement
account ("SRA"), if certain requirements are met. Under an SRA, the employer
contributes elective employee compensation deferrals up to a maximum of $6,000 a
year. The employer must, in general, make a fully vested matching contribution
for employee deferrals up to 3% of compensation.

TAX-SHELTERED ANNUITY ("TSA")

  Section 403(b) of the Code permits the purchase of TSAs by employees of public
schools and certain charitable, educational and scientific organizations
described in Section 501(c)(3) of the Code. These qualifying employers may make
contributions to the Contracts for the benefit of their employees.  Such
contributions are not includible in the gross income of the employee until the
employee receives distributions from the Contract.  The amount of contributions
to the TSA is limited to certain maximums imposed by the Code. Furthermore, the
Code sets forth additional restrictions governing such items as transferability,
distributions, non-discrimination and withdrawals.  (Information about taking a
loan against a TSA Contract is described in detail in the SAI.)

  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 thereon).

TEXAS OPTIONAL RETIREMENT PROGRAM ("ORP")
   
  The ORP is a defined contribution plan available to certain employees of Texas
institutions of higher education. An ORP is an individualized plan in which each
participant selects investments through various companies offering a variety of
investment products such as annuity contracts and mutual fund investments. Since
participants manage their own personal investment accounts, ORP entails more
individual risks and responsibility  than other Qualified Plans. Benefits are a
direct result of the amounts contributed and the return on investments made by
each participant. Upon  termination from Texas public higher education
employment, ORP participants  who have more than one year of participation are
vested in the ORP and retain control over all investments, both employee and
employer contributions.  Participants with one year or less of participation in
the ORP are not vested and employer  contributions must be returned to the
institution.  THEREFORE, DURING YOUR  FIRST YEAR OF PARTICIPATION IN THE ORP,
YOUR EMPLOYER'S CONTRIBUTIONS WILL BE  INVESTED IN THE MONEY MARKET FUND
ACCOUNT. AFTER THE FIRST YEAR, EMPLOYER  CONTRIBUTIONS CAN BE MAINTAINED IN THE
MONEY MARKET FUND ACCOUNT OR TRANSFERRED TO ANY OF THE OTHER VARIABLE  FUND
ACCOUNTS, SUBJECT TO OUR GENERALLY APPLICABLE RULES FOR TRANSFERS.    

  Certain redemption restrictions apply to Contracts issued under the ORP. With
respect to Contracts issued under the ORP, state law provides that withdrawal
benefits are available only if the participant obtains the age of 70 1/2 years
or terminates participation in the ORP because of death, retirement, including
disability retirement, or terminating employment in all  public institutions of
higher learning in Texas. Under Texas law a  participant may not transfer
ownership of an ORP plan unless under a  qualified domestic relations order
issued by a court having appropriate  jurisdiction. The value of such Contracts
may, however, be transferred to other Contracts or other carriers during
participation in these retirement  programs, subject to any charges that would
apply in the case of any other  surrender of the Contract. Appropriate
disclosure regarding the restrictions  on redemption imposed by the ORP will
also be found in sales materials  accompanying this Prospectus. On the
Application, there will be a statement  you will be required to sign
acknowledging that you have read the  restrictions on redemption imposed by the
ORP.
   
  ALL QUALIFIED PLANS REFERENCED IN THIS PROSPECTUS INCLUDE SPECIAL PROVISIONS
CHANGING OR RESTRICTING CERTAIN RIGHTS AND BENEFITS OTHERWISE AVAILABLE TO
NONQUALIFIED PLANS FUNDED BY THE CONTRACT.  IN PARTICULAR, THE FIXED FUND
ACCOUNT IS NOT PART OF THE CONTRACT ISSUED UNDER THE ORP. YOU SHOULD CAREFULLY
READ YOUR CONTRACT, RIDERS AND ENDORSEMENTS TO REVIEW SUCH CHANGES OR
LIMITATIONS. ADDITIONAL CHANGES AND LIMITATIONS MAY APPEAR IN ANY OTHER
QUALIFIED PLAN DOCUMENTS OR IN LAWS OR REGULATIONS APPLICABLE TO QUALIFIED
PLANS. THE CHANGES AND LIMITATIONS MAY INCLUDE:  RESTRICTIONS ON OWNERSHIP,
TRANSFERABILITY, ASSIGNABILITY, CONTRIBUTIONS,  DISTRIBUTIONS, AS WELL AS
REDUCTIONS TO THE MINIMUM ALLOWABLE PREMIUM PAYMENT  FOR AN ANNUITY CONTRACT AND
ANY SUBSEQUENT ANNUITY YOU MAY PURCHASE FOR USE  AS A QUALIFIED PLAN.
ADDITIONALLY, VARIOUS PENALTY AND EXCISE TAXES MAY APPLY TO CONTRIBUTIONS OR
DISTRIBUTIONS MADE IN VIOLATION OF APPLICABLE  LIMITATIONS.    

LEGAL PROCEEDINGS
- -----------------

  As of the date of this Prospectus, there are no legal proceedings to which the
Company, the Separate Account or the Distributor is a party except  for routine
litigation which the Company does not believe is relevant to the Contracts

PERFORMANCE INFORMATION
- -----------------------

YIELD AND TOTAL RETURN
   
  From time to time, the Separate Account 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.  The Separate Account also may
advertise the "effective yield" of the USAA Life Money Market Fund Account,
which is calculated similarly but, when annualized, the income earned by an
investment in the 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

  The Separate Account's performance reported from time to time in
advertisements and sales literature may be compared to generally accepted
indices or analysis such as those provided by Lipper Analytical Services,  Inc.,
Standard & Poor's Corporation and Dow Jones. Performance ratings reported
periodically in financial publications such as Money Magazine, Forbes, Business
Week, Fortune, Financial Planning and The Wall Street Journal may also be used.
For more information, see the Statement of Additional Information.
   
VARIABLE FUND ACCOUNT PERFORMANCE    
   
  The investment performance information for each Variable Fund Account will
generally reflect the investment performance of the  corresponding Fund. Table I
below shows the average annual total return of  each Variable  Fund Account for
the periods indicated. The average annual total return figures are computed in
accordance with a formula prescribed by the SEC.  Table II shows the cumulative
total returns of each Variable  Fund  Account for the periods indicated.

EFFECT OF TAX-DEFERRED ACCUMULATIONS
   
  Unlike taxable investments, contributions to tax-favored Qualified Plans and
Nonqualified Plan Contracts provide tax-deferred treatment on  earnings. In
addition, contributions to tax-favored Qualified Plans  ordinarily are not
subject to income tax until withdrawn. As shown in the  chart below, investing
in a tax-favored program increases the accumulation  power of savings over time.
The more taxes saved and reinvested in the program, the more the accumulation
power effectively grows over the years.  The Variable Annuity Surrender Value as
indicated  in the charts below represent the lump-sum withdrawal  remaining
after payment of federal income taxes.    

  To further illustrate the advantages of tax-deferred savings using a 28%
federal tax bracket, an annual fixed yield (before the deduction of any  fees or
charges) of 10% under a tax-favored Qualified Plan in which tax  savings were
reinvested has an equivalent annual fixed yield of 13.9% under a  conventional
savings program. The 10% yield on the tax-favored Qualified  Plans would be
reduced by the assumed impact of income taxes upon withdrawal.  The amount of
this reduction in yield will vary depending upon the timing of withdrawals. 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 indicated above, contributions to tax-favored Qualified Plans are not
subject to federal income tax unless and until withdrawn. Accumulation  under
tax-favored 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.

  By taking into account the current deferral of taxes, these contributions to
tax-favored Qualified Plans increase the amount available  for savings by
decreasing the relative current out-of-pocket cost of the  investment.

EFFECT OF TAX-DEFERRED ACCUMULATIONS

  The charts below compare accumulations attributable to premium payments to (1)
Contracts purchased with pre-tax dollars under a tax-favored Qualified Plan and
(2) Nonqualified Contracts purchased with after-tax dollars to taxable
investments. 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 may 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 Period. It also assumes a 28% tax rate and a
10% rate of return and reflects the deduction of 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
will differ.

This hypothetical chart compares the results of investing an initial after-tax

                              GENERAL INFORMATION
                                        
    
  USAA Life is a stock insurance company incorporated in the State of 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 all states, including the District of
Columbia, 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 conglomerate).     


                                  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 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 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 

                                       4

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 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 and schedules of
USAA Life Insurance Company and its subsidiary as of December 31, 1997 and 1996
and for each of the years in the three-year period ended December 31, 1997 have
been included in the registration statement in reliance upon the report of KPMG
Peat Marwick 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 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 $32,325 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     

                                       5
<PAGE>
 
    
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:     


             Effective Yield = [(Base Period Return + 1)365/7] - 1
    
  For the seven day period ended December 31, 1997, the current yield of the
USAA Life Money Market Fund Account was 4.29%.
                                        
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 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.

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

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 as of December 31, 1997, and 1996, and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the years in the three-year period ended December 31, 1997.  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 as of December 31, 1997, and 1996, and the results of their operations
and their cash flows for each of the years in the three-year period ended
December 31, 1997 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 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) 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 future policyholder benefits) reflected in
        stockholders' equity.

        Bonds, at amortized cost of approximately $281,206, and $2,876 were on
        deposit with various state governmental agencies at December 31, 1997,
        and 1996 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 1997 deposits include
        $278,333 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 nonredeemable 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
        future policyholder benefits) reflected in stockholders' equity.

        Real estate mortgages and policy loans are carried at their unpaid
        principal balances with interest rates ranging from 4.80% to 10.0% at
        December 31, 1997.

        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.

                  Notes to Consolidated Financial Statements

                            (Dollars in Thousands)


    (c) 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, 1997 and 1996, cash and cash equivalents
        include $268, and $362, respectively, of separate account purchases
        awaiting reinvestment.  These funds are restricted from the Company's
        use.

    (d) 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.

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

        The fair value estimates of the Company's financial instruments were
        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.

    (f) 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.

    (g) 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.

                            (Dollars in Thousands)

    (h) Insurance reserves
        ------------------

        Included in 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.

    (i) 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.

    (j) 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.

    (k) 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 8% of the total life insurance in force at December 31, 1997, and 9%
        of life insurance in force at December 31, 1996.  Participating policies
        accounted for 13% of the premium income in 1997, and 15% of the premium
        income in 1996. The provision for policyholders' dividends is based on
        current dividend scales.

        The Company guarantees to pay dividends in aggregate, on all policies
        issued after December 31, 1983, in the total amount of $15,092 in 1998.

        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.

    (l) Reclassifications
        -----------------

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

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

    The Company prepares separate statutory financial statements in accordance
    with accounting practices prescribed or permitted by the Insurance
    Department of Texas. 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 is currently
    undergoing a  codification project whereby a comprehensive accounting and
    reporting basis may be adopted which is intended to replace prescribed or
    permitted accounting practices.

    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:

Deferred income tax benefit for the years ended December 31, 1997, 1996, and
1995 was primarily attributable to differences between the valuation of
assets and insurance liabilities for financial reporting and tax purposes.

   The tax effects of temporary differences that give rise to significant
   portions of the deferred tax assets and deferred tax liabilities at December
   31 are presented below:

    Management believes that the realization of the deferred tax asset is more
    likely than not based on the expectation that such benefits will be utilized
    in the future consolidated tax returns of the USAA group.

    At December 31, 1997, and 1996, the Company had the following Federal income
    tax payable/receivable amounts:

(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.  Financial Accounting
    Statement 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.

</TABLE> 

    The carrying amounts of financial assets and liabilities shown in the above
    table are included in the balance sheet under the indicated captions with
    the following exceptions: other invested assets are included in other
    assets, deferred annuities and annuities without life contingencies are
    included in funds on deposit, policyholder dividend accumulations are
    included in funds on deposit, and policy dividends declared and unpaid 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 and the mortgage loan
    component of other assets 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.

    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.

                            (Dollars in Thousands)


    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 $73,136, $70,713, and $66,787 for 1997,
    1996, and 1995, respectively.  The aggregate amount of the Company's
    allocations to affiliates was $4,376, $4,742, and $3,910 for 1997, 1996, and
    1995, 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 $3,037, $2,793, and $2,941 for 1997, 1996 and 1995,
    respectively.

    The Company also received premium and annuity considerations from USAA of
    $4,201, $4,093, and $6,145 in 1997, 1996, and 1995, 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, 1997, 1996, and
    1995 the Company had no liability for borrowed money. The Company borrowed
    $3,598,125 during 1997, $2,566,042 during 1996, and $1,809,466 during 1995,
    through the use of these funding agreements.  The interest associated with
    these intercompany funding agreements was $855, $660, and $898 in 1997,
    1996, and 1995, respectively.

    In 1996, the Company exercised a put option on a $20,000 medium term note
    from CAPCO.

(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% goes to a coinsurance
    pool which is placed with a number of reinsurers on a quota share basis.

    Additionally, the Company's entry into the Bank Owned Life Insurance (BOLI)
    business resulted in 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 in 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 $4,077,094, $3,595,801 and
    $3,690,040 is ceded on a yearly renewable term basis; $4,684,726, $939,290,
    and $716,596 is ceded on a coinsurance basis; and $957,267, $952,599, and
    $1,000,581 is ceded in accordance with a stop loss agreement at December 31,
    1997, 1996, and 1995, respectively. Reinsurance amounts related to insurance
    reserves, funds on deposit, and paid losses totaled $204,607, and $13,023 at
    December 31, 1997 and 1996, respectively.  Premium revenues and interest
    credited to policyholders were reduced by $204,109, $11,837, and $11,072 for
    reinsurance premiums ceded  during the years ended December 31, 1997, 1996,
    and 1995, respectively.  Benefits were reduced by $196,062, $7,838, and
    $7,435 for reinsurance recoverables during the years ended December 31,
    1997, 1996, and 1995, respectively.  One reinsurer accounts for 90% of the
    amount recoverable from reinsurers at December 31, 1997.

    Reinsurance amounts related to accident and health insurance reserves and
    paid losses totaled $17,981 and $15,786 at December 31, 1997 and 1996,
    respectively.  Premium revenues were reduced by $3,297, $3,117, and $3,134
    for reinsurance premiums ceded during the years ended December 31, 1997,
    1996, and 1995, respectively.  Benefits were reduced by $3,268, $3,604, and
    $3,299 for reinsurance recoverables during the years ended December 31,
    1997, 1996, and 1995, respectively.

    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.

                            (Dollars in Thousands)

     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.

(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 $2,200,
     $1,830, and $1,601 were paid in 1997, 1996, and 1995 respectively, and $94
     has accrued since the last payment on December 15, 1997.

     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,
     1997, 1996, and 1995. Dividends of $45,546, $14,000, and $18,000 were paid
     on the common stock during 1997, 1996, and 1995, respectively. The 1997
     dividend was paid in cash and equity securities.  The equity securities
     transferred had an original cost of $11,560, a fair value of $22,546, and
     the Company recognized gain of $10,986.

(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 $47,976 in 1997 and are limited to $66,872 in 1998.  Dividends
    are paid as determined by the Board of Directors and at its discretion.

    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) 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 $3,746, $4,847, and
         $1,913 in 1997, 1996 and 1995, respectively. At December 31, 1997 and
         1996, a liability of $899 and $1,612, 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 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 total postretirement benefit
         cost allocated to the Company was approximately $737, $682, and $843 in
         1997, 1996, and 1995, respectively. At December 31, 1997 and 1996, a
         liability of $974 and $186, respectively, was recorded which represents
         the excess of the net periodic postretirement benefit cost allocated to
         the Company over its allocated funding requirements.

     (c) Postemployment benefits
         -----------------------

         All employees of the Company who suffer total disability as a result of
         illness or injury are eligible for long-term disability benefits under
         a plan administered by USAA.

         The postemployment benefit cost allocated to the Company is not
         significant.

(13) Separate account
     ----------------

     The Separate Account is a segregated asset account established under Texas
     law through which USAA Life Insurance Company invests the premium payments
     received from Contract Owners.  The assets of the Separate Account are the
     property of the Company.  However, only the assets of the Separate Account
     in excess of the reserves, and other Contract liabilities with respect to
     the Separate Account, 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, credited to or
     charged against the Separate Account without regard to other income, gains
     or losses of the Company.  The Company's obligations arising under the
     Contracts are general corporate obligations.

     The Separate Account currently is divided into nine 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. 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 Annuity Money
     Market Fund, at amortized cost, which approximates market value.

     The Company incurs mortality and administrative expenses on behalf of
     Separate Account contract holders.  The Company collects fees for these
     expenses from contract holders 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
     1997 and 1996.

(14) 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 $1,953, $2,437 and $4,823 to various state
     guaranty associations during the years ended December 31, 1997, 1996, and
     1995, respectively. The Company accrues its best estimate for known
     insolvencies. At December 31, 1997 and 1996 accounts payable and accrued
     expenses include $8,931 and $9,292, respectively, related to estimated
     assessments.

(15) Subsequent Event
     ----------------

     In January 1998, the Company declared and paid a dividend to stockholders
     of $33,928. The dividend was paid in equity securities with an original
     cost of $21,951, resulting in a realized gain of $11,977.

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

  Information in response to this Item is incorporated by reference to Exhibit
20 to Post-Effective Amendment No. 6 to the USAA Life Investment Trust's
Registration Statement on Form N-1A (File No. 33-82270).


ITEM 27.  NUMBER OF CONTRACT OWNERS

  As of  April 15, 1998, there were 6,210 owners of Contracts covered by this
Registration Statement.


ITEM 28.  INDEMNIFICATION

  The information called for by this Item is incorporated herein by reference to
Article IX of the By-Laws of USAA Life, filed as Exhibit 6(b) to this
Registration Statement; to Section 9 of the Amended and Restated Underwriting
and Administrative Services Agreement, filed as Exhibit 8(c) to this
Registration Statement; to Section 14 of the Amended and Restated Distribution
and Administration Agreement, filed as Exhibit 3 to this Registration Statement;
to paragraph 8(b) of the Participating Contract and Policy Agreement, as
amended, filed as Exhibit 8(d)(ii) to this Registration Statement; and to
Section 14 of the Transfer Agent Agreement, as amended, filed as Exhibit 8(c) of
Pre-Effective Amendment No. 1 to the Form N-1A Registration Statement of USAA
Life Investment Trust (File No. 33-82270 and No. 811-8672).
     
  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.

(a) USAA Investment Management Company ("USAA IMCO") is the principal

The following resolution was adopted at a Meeting of the Board of Directors on
February 7, 1994:    


                          USAA LIFE INSURANCE COMPANY

     WHEREAS, the Board of Directors (the "Board") has determined, after
presentation by USAA Life Insurance Company (the "Company"), that it is
desirable for the Company to provide variable annuity contracts to its customers
and prospective customers;


     NOW THEREFORE, The Board resolves as follows:


     RESOLVED, that the Company will amend its Certificate of Authority in those
states where required in order to authorize it to sell variable annuity
contracts.  The Company will file the variable annuity contract form in all
fifty states and any other legal documents, affidavits, exhibits or any other
information required by the various State Insurance Departments.


     RESOLVED, that a Separate Account of USAA Life Insurance Company (the
"Separate Account") be established in accordance with the provisions of Chapter
3, Article 3.75 of the Texas Insurance Code, and the Regulations promulgated
thereunder, for the purpose of providing a funding medium to support reserves
under such variable annuity contracts as may be issued by the Company.


     RESOLVED, that the Company and its Directors, Officers, employees, and
affiliates with respect to the purchase or sale of investments of the Separate
Account will adhere to standards of conduct that comply with 15 United States
Code (S) 80a-17, as amended, and applicable rules and regulations thereunder and
the Officers are directed to adopt and implement a Code of Ethics to assure
compliance with these legal requirements.


     RESOLVED, that the Officers of the Company are authorized to take all
actions which they deem necessary or appropriate to issue and sell variable
annuity contracts. Such authority shall include, without limitation, registering
the product in an amount (which may be in an indefinite amount) from time to
time under the Securities Act of 1933, as amended, registering the Separate
Account as a unit investment trust under the Investment Company Act of 1940, as
amended, and filing any exemptive application or applications, and any amendment
thereto with respect to the product or the Separate Account, under the
Investment Company Act of 1940, as amended, and taking all other actions
necessary or appropriate in order that such proposed issue and sale of the
variable annuity contracts and operation of the Separate Account may comply with
the requirements of the Securities Act of 1933, as amended, the Investment
Company Act of 1940, as amended, the Securities Exchange Act of 1934, as
amended, the Investment Advisers Act of 1940, as amended, and all other
applicable federal and state laws and regulations.

                                       1
<PAGE>
 
     RESOLVED, that the Separate Account may have amounts allocated thereto
(including proceeds applied under optional modes of settlement) to provide for
variable annuity contracts (and benefits incidental thereto) payable in variable
amounts. The Separate Account shall be established and maintained pursuant to
the laws of Texas under which income, gains and losses, whether or not realized,
from assets allocated to the Separate Account, are, in accordance with the
applicable contract, credited to or charged against the Separate Account without
regard to other income, gains or losses of the Company. The Separate Account
shall be legally segregated, the assets of the Separate Account shall, at the
time during the year that adjustments in the reserves are made, have a value at
least equal to the reserves and other contract liabilities with respect to the
Separate Account, and pursuant to Securities and Exchange Commission Regulation
17 CFR (S)270.0-1 at all other times, shall have a value approximately equal to
or in excess of such reserves and liabilities, and that portion of such assets
having a value equal to, or approximately equal to, such reserves and contract
liabilities shall not be chargeable with liabilities arising out of any other
business which the Company may conduct.


     RESOLVED, that the variable annuity contract will provide a fixed interest
rate option through which contract owners may allocate premium to the Company's
General Account in addition to the Separate Account.


     RESOLVED, that the fundamental investment policy of the Separate Account
shall be to invest or reinvest the assets of the Separate Account in securities
issued by such investment company or investment companies registered under the
Investment Company Act of 1940, as amended, as the Officers may select and
designate, consistent with the terms of the variable annuity contract and
applicable laws.


     RESOLVED, that one or more Sub-Accounts be established within the Separate

          General Account (the "Discretionary amount") under certain conditions;
          appointed certain individuals as agents to receive service of process

          financial commitment to the Separate Account as well as, ultimately,
          the variable annuity contractholders purchasing said product, to
          defray expenses not anticipated or briefed to the Board of the Special
          Meeting, and to attempt to maintain the projected "break-even" or
          "profitability" target of five (5) years, has recommended

          increase said Discretionary amount by eleven million dollars
          ($11,000,000.00); and


          WHEREAS, the management of the Company, in order to have at least one
          officer of the Board serve as agent for service of process for the
          purposes stated above herein, recommends the Assistant Secretary
          thereof to be so named; and

          WHEREAS, the management of the Company finds it desirable and,

  NOW, THEREFORE, in consideration of the mutual covenants herein contained, and
of the mutual expectations of benefit occurring from the activities herein
contemplated, the parties hereto agree as follows:

1.  Appointment of the Distributor

  The Company  shall during the term of this Agreement  take all action which is
required to cause the Contracts and Policies to comply as insurance products,
interests thereunder to comply as registered securities, and the Separate
Account and the Life Insurance Separate Account to qualify as registered
investment companies, under all applicable federal and state laws and
regulations.  The Company shall immediately notify the Distributor of any
failure  to comply or qualify or of any order or instruction of any regulatory,
judicial or governmental authority to cease or limit the offer or sale of the
Contracts or Policies or any of the Company's operations related thereto.

  The Company appoints the Distributor and the Distributor  shall act as the
exclusive principal underwriter for the sale of the Contracts and Policies to
the public, during the term of this Agreement, in each state and other
jurisdictions in which such Contracts and Policies may lawfully be sold. The
Distributor shall offer the

                                       6
<PAGE>
 
Contracts and Policies for sale and distribution, but shall be under no
obligation to effectuate any particular amount of sales of Contracts or
Policies. In this connection, the Distributor shall distribute prospectuses of
the Trust together with prospectuses of the Separate Account for the Contracts
and the prospectuses of the Life Insurance Separate Account, as required by the
SEC.

  The Distributor in its capacity as broker-dealer will be solely responsible
for monitoring and controlling the activities of all Associated Persons involved
in the distribution and sale of the Contracts and Policies.  Applications for
the Contracts and Policies shall be solicited only by Associated Persons who are
registered with the NASD as representatives of the Distributor ("Registered
Representatives"), and who are duly and appropriately licensed or otherwise
qualified to sell such Contracts and Policies in each state or other
jurisdiction.  The Company shall undertake to appoint the Distributor's
Registered Representatives as life insurance agents of the Company, which agents
will be salaried employees of the Company.  Completed applications for the
Contracts or Policies shall be transmitted directly to the Company or to an
appointed Third Party Administrator or other designated agent (each a "TPA").

  Initial and subsequent premium payments under the Contracts or Policies

                                       7
<PAGE>
 
shall be made payable to the Company or its designee and any such payments which
come into the possession of the Distributor shall be immediately delivered to
the Company or its designee. The Company and any TPA shall provide all Contract
and Policy issue services at their own expense. Anything in this Agreement to
the contrary notwithstanding, the Company retains the ultimate right to control
the sale of the Contracts and Policies, including the right to suspend sales in
any jurisdiction or jurisdictions, and to appoint and discharge insurance agents
of the Company. The Company shall, however, cooperate with and assist USAA IMCO
to insure that USAA IMCO as broker-dealer controls the manner and whether or not
the Contracts and Policies are sold for purposes of compliance with federal and
state securities law. The Distributor and the Company shall be held to the
exercise of reasonable care in carrying out the provisions of this Agreement.

2.  Registration of Representatives

  The Distributor shall be responsible for ensuring that the individual
Registered Representatives offering or selling the Contracts and Policies are
duly registered and qualified pursuant to the 1934 Act, NASD regulations, and
any other required securities regulatory body.

                                       8
<PAGE>
 
3.  Life Insurance Licensing

  The Company shall be responsible for ensuring that the Registered
Representatives are duly qualified, under the insurance laws of the applicable
jurisdictions, to sell the Contracts and Policies.


4.  Suitability

  The Company desires to ensure that Contracts and Policies sold by the
Distributor will be issued to purchasers for whom the Contracts or Policies will
be suitable.  The Distributor shall establish written procedures which will
require Registered Representatives to review all applications to determine that
the Contracts or Policies are a "suitable" investment vehicle for the applicant.
While not limited to the following, a determination of suitability shall be
based on information furnished to a Registered Representative after reasonable
inquiry of such applicant concerning the applicant's investment objectives and
financial situation and needs, including the likelihood that the applicant will
make sufficient premium payments to derive the benefits thereof.  Registered
Representatives of USAA IMCO will review every application for the Contracts or
Policies to insure that it meets the "suitability requirement" detailed in the
NASD's Conduct Rules.

                                       9

5.  Sales Aids; Promotional Material

  The Company shall have responsibility for furnishing to the Distributor's
Registered Representatives all sales aids, and promotional material related to
the solicitation and sale of the Contracts and Policies, all at the Company's
expense, and the Distributor shall not use any other such aids, or material
without the specific advance approval of the Company.  Such material shall have
been approved in advance by the Distributor.  The Distributor, at its
discretion, directly or through the Company as its agent, shall cause such
material to be filed with and reviewed by the NASD, the SEC, or any other
required securities regulatory body, as appropriate.  The Company, at its
expense, shall make timely filings of all such aids, material, or proposals with
any insurance regulatory authorities, as required.

  No person shall, in connection with the offer or sale of the Contracts or
Policies, make any representations or communicate any information regarding the
Contracts, Policies or the Company which are not contained in materials approved
pursuant to this Section 5 or in the then-effective 1933 Act Registration
Statement for the Separate Account and the Life Insurance Separate Account,
respectively.

                                       10
<PAGE>
 
6.  Compensation

  The Company shall pay the salaries and employee fringe benefits of the
Registered Representatives of the Distributor.  Such salaries and benefits shall
be their sole compensation and shall not be related to the volume of the sales
of the Contracts or Policies made during a specified time period.

  The Company will receive all amounts charged as the Fixed Fund Account
Withdrawal Charge under the Contracts.  The parties understand that the Company
is charging the Fixed Fund Account Withdrawal Charge to help enable the Company
to declare higher rates of interest than it could otherwise declare, is
deducting no specific charge for the cost of distributing the Contracts, and is
assuming the risk that the charges under the Contract may be insufficient to
cover the Company's actual expenses and costs assumed in connection with the
Contracts.


7.  Administration, Records and Confirmations

  The Company shall be primarily responsible for the internal record-keeping and
general office administration necessary for the sale of the Contracts and
Policies subject to the Distributor's review and approval.  The Company in its
discretion and

                                       11
<PAGE>
 
with the understanding of the Distributor, may delegate some or all of its
record-keeping functions to a TPA pursuant to a separate written agreement. The
books and records maintained by the Company or TPA as agent for the benefit of
the Distributor will conform to the requirements of Rule 17a-3 and Rule 17a-4
under the 1934 Act, and as further amplified in SEC Release 34-8389.
Furthermore, such books and records shall remain the property of the
Distributor, shall be surrendered promptly to the Distributor at its request
without charge, and shall at all times be subject to inspection by the
Distributor, the SEC pursuant to Section 17(a) of the 1934 Act and any other
appropriate governmental agency.

  The Distributor shall have responsibility for maintaining the records required
of it by applicable law or regulations with respect to broker-dealer operations,
although, in the Distributor's discretion and at the Company's expense, the
Distributor may use the Company or any TPA as its agent for this purpose, as
described in the preceding paragraph.

  Any and all books, accounts, and records of the Company, the Separate Account,
the Life Insurance Separate Account, and the Distributor as may pertain to the
Contracts, Policies and this Agreement shall be maintained so as to clearly and

                                       12
<PAGE>
 
accurately disclose the nature and details of Contract and Policy transactions
or any transactions related thereto.  The Distributor shall keep confidential
any information obtained pursuant to this Agreement and shall disclose such
information only if the Company has authorized such disclosure, or if such
disclosure is expressly required by applicable federal or state authorities.

  The Distributor, directly or through the Company or any TPA as  the
Distributor's agent (at the Company's expense), shall, upon or prior to the
completion of each Contract or Policy transaction for which a confirmation is
legally required, send a written confirmation to the Contractowner or
Policyowner for each such respective transaction, in a form and manner that
complies with the requirements of the 1934 Act, state laws and regulations, and
the disclosure requirements of the NASD.  Such confirmations will be furnished
to all Contractowners or Policyowners in accordance with securities laws, will
reflect the facts of the transaction, and will show that they are being sent by
the Company on behalf of the Distributor.  The parties agree that the form and
the manner of use of confirmations in connection with transactions occurring in
Contract or Policy accounts shall be supervised by the Distributor.  The Company
shall prepare and distribute such confirmations in accordance with the
Distributor's instructions.  The Company  shall  make no changes

                                       13
<PAGE>
 
or variations in either the form or the manner of distribution of such
confirmations without the written approval of the Distributor and shall cause
such confirmations to be issued as directed by the Distributor and on behalf of
the Distributor.


8.  Examination and Proceedings

  The Distributor and the Company  shall cooperate fully in any insurance
regulatory examination, investigation, or proceeding or any judicial proceeding
arising in connection with the Contracts and Policies distributed under this
Agreement.  The Distributor and the Company  shall cooperate fully in any
securities regulatory examination, investigation or proceeding or any judicial
proceeding with respect to the Company, the Distributor, and their respective
affiliates, agents and representatives to the extent that such examination,
investigation, or proceeding is in connection with Contracts and Policies
distributed under this Agreement.  The Distributor shall furnish applicable
federal and state regulatory authorities with any information or reports in
connection with its services under this Agreement, which authorities may request
in order to ascertain whether the Company's operations are being conducted in a
manner consistent with any applicable law or regulations.

                                       14
<PAGE>
 
  In the case of an oral or written consumer or regulatory agency complaint, the
Distributor and the Company shall promptly notify the other and shall coordinate
and fully cooperate in responding to such complaints.  The Distributor and the
Company shall develop procedures to coordinate, investigate and respond to such
complaints.


9.  Other Compliance Requirements

  The Distributor shall  be responsible for the securities activities of, and
for securities law compliance by, any Associated Person engaged directly or
indirectly in the flexible premium variable annuity operation or the flexible
premium variable universal life insurance operation.  This shall include (i)
compliance with NASD Conduct Rules and with federal and state laws and
regulations, and (ii) the appropriate training and qualification of Associated
Persons, at the Company's expense.  The Distributor, in order to discharge its
duties under this provision of the Agreement, shall be authorized to and shall
designate such Company personnel as it deems necessary to qualify as limited or
general securities principals ("Limited Principals" or "General Principals"),
which individuals shall supervise the securities activities of, and securities
law compliance by, those Registered Representatives selling the Contracts and
Policies, all in accordance with applicable laws, regulations

                                       15
<PAGE>
 
and NASD requirements. Further, the Distributor shall have the authority to
require such written compliance procedures as it deems advisable to be
established by the Company with respect to any aspect of the Company's business
that affects broker-dealer operations with respect to the Contracts and Policies
and, through the Limited and General Principals, monitor and enforce compliance
with said procedures. The Company shall cooperate and provide any assistance
required by the Distributor in order to insure that the Distributor and
Associated Persons engaged directly or indirectly in the sale of the Contracts
and Policies remain in compliance with any such compliance procedures and
appropriate securities laws, regulations and the NASD`s General Rules and
Conduct Rules.

  The Distributor will execute such papers and do such acts and things as shall
from time to time be reasonably requested by the Company for the purpose of (a)
maintaining the registration of the Contracts interests and Policy interests
under the 1933 Act and the Separate Account and the Life Insurance Separate
Account under the 1940 Act, and (b) qualifying and maintaining qualification of
the Contracts and Policies for sale under the applicable laws of any state.

  Upon the completion of each transaction for which a confirmation is legally

                                       16
<PAGE>
 
required, the Company or a TPA shall, on behalf of the Distributor, send a
written confirmation of such transaction reflecting the facts of the
transaction.

10.  Contract Payments

Policies, including payments representing Contract or Policy loans, full and
partial surrenders, and amounts paid under Contract or Policy settlement
options.


11.  Company Services

  The Company shall provide or arrange to provide, at its expense, all necessary
services in connection with the operational aspects of the Contracts and
Policies.  These services shall include, but are not limited to, actuarial,
accounting, data processing, legal, regulatory, Contractowner and Policyowner
service and any other actions required by the Company in its discretion.  In
addition to these services, or other services provided hereunder, the Company
shall provide such executive, clerical, and other personnel related services as
may be required to carry out the Company's obligations under this Agreement,
including its obligation to perform certain functions on the Distributor's
behalf.

                                       17
<PAGE>
 
12.  Expense Allocation

  Expenses under this Agreement are allocated in this Section 12.  If, at a
later time, the Agreement gives rise to other expenses, they shall be allocated
as the parties may decide in writing at that time.  The Company hereby agrees
that it will bear the cost of the Associated Persons' salaries and securities
licensing fees; securities registration expenses and filing fees with respect to
the Contracts and the Separate Account and the Policies and the Life Insurance
Separate Account; costs of preparing, printing and distributing all
prospectuses, statements of additional information, notices, periodic reports,
and proxy solicitation material with respect to the Contracts and Policies,
costs of sales literature and other promotional material, applications for
exemptions, requests for no-action letters, and all amendments to any of the
above; costs of preparing, printing, and filing Contract and Policy forms; and
direct legal and accounting expenses in connection with any of the foregoing.
Any of these expenses which may be initially assumed by the Distributor will be
reimbursed to it by the Company upon presentation of the appropriate
documentation in writing evidencing such expenditures.  Nothing in this
Agreement shall be deemed to allocate any operational or organizational expense
of the Trust, or the offer and sale of its shares, which expense shall be
allocated pursuant to a separate agreement or agreements pertaining to that
entity

                                       18
<PAGE>
 
13.  Indemnification

  a)  Whenever the Company is referred to in this Section (13), it is to be
construed to specifically also refer to and include the Separate Account and the
Life Insurance Separate Account.

  b)  The Company shall indemnify and hold harmless the Distributor, its agents,
employees and each person, if any, who controls the Distributor against any
loss, liability, claim, damage or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, claim, damage or expense
and reasonable counsel fees incurred in connection therewith) arising by reason
of any person's acquiring any Contract or Policy, which may be based upon any
federal or state securities act, or on any other statute or at common law, (i)
on the ground that the registration statement or related prospectus, as from
time to time amended and supplemented, or the annual or interim reports to
Contractowners or Policyowners, any published marketing materials or
communications with any Contractowner or Policyowners or prospective
Contractowner or Policyowner concerning the Contract or Policy, respectively,
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein not misleading, unless such statement or omission was made in reliance
upon, and in conformity with, information furnished to the Company in

                                       19
<PAGE>
 
connection therewith by or on behalf of the Distributor; or (ii) on the ground
that a TPA (other than a TPA controlled by Distributor) failed to comply with
any applicable securities law and regulations in connection with its rendering
of Contract or Policy issue, recordkeeping, or confirmation services under this
Agreement; provided, however, that in no case (a) is the indemnity of the
Company in favor of the Distributor and any such controlling persons to be
deemed to protect the Distributor or any such controlling persons thereof
against any liability to the Company or its Contractowners or Policyowners to
which the Distributor or any such controlling persons would otherwise be subject
by reason of willful misfeasance, bad faith or gross negligence in the
performance of its duties or by reason of reckless disregard of its obligations
and duties under this Agreement, or (b) is the Company to be liable under its
indemnity agreement contained in this paragraph with respect to any claim made
against the Distributor or any such controlling persons, unless the Distributor
or such controlling persons, as the case may be shall have notified the Company
in writing within a reasonable time after the summons or other first legal
process giving information of the nature of the claim shall have been served
upon the Distributor or such controlling persons (or after the Distributor or
such controlling persons shall have received notice of such service on any
designated agent), but failure to notify the Company of any such claim shall not
relieve the Company from any liability which

                                       20
<PAGE>
 
the Company may have to the person against whom such action is brought otherwise
than on account of the Company indemnity agreement contained in this paragraph.
The Company will be entitled to participate at its own expense in the defense,
or, if it so elects, to assume the defense of any suit brought to enforce any
such liability, but if the Company elects to assume the defense, such defense
shall be conducted by counsel chosen by it and satisfactory to the Distributor
or such controlling person or persons, defendant or defendants in the suit. In
the event the Company elects to assume the defense of any such suit and retain
such counsel, the Distributor or such controlling person or persons, defendant
or defendants in the suit, shall bear the fees and expense of any additional
counsel retained by the Distributor or such controlling person or persons, but,
in case the Company does not elect to assume the defense of any such suit, it
will reimburse the Distributor or such controlling person or persons, defendant
or defendants in the suit, for the reasonable fees and expense of any counsel
retained by them. The Company shall promptly notify the Distributor of the
commencement of any litigation or proceedings against the Company or any of its
officers, directors, employees or agents in connection with the issuance or sale
of the Contracts or Policies.

  c)  The Distributor shall indemnify and hold harmless the Company, its agents,
employees and each person, if any, who controls the Company against any

                                       21
<PAGE>
 
loss, liability, claim, damage or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, claim, damage or expense
and reasonable counsel fees incurred in connection therewith) arising by reason
of any person's acquiring any Contract or Policy, which may be based upon any
federal or state securities act, or on any other statute or at common law, on
the ground that the registration statement or related prospectus, as from time
to time amended and supplemented, or the annual or interim reports to
Contractowners or Policyowners, any published marketing materials or
communications with any Contractowner or Policyowner or prospective
Contractowner or Policyowner concerning the Contract or Policy, respectively,
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein not misleading, unless such statement or omission was made in reliance
upon, and in conformity with, information furnished in connection therewith by
or on behalf of the Company; provided, however, that in no case (a) is the
indemnity of the Distributor in favor of the Company and any such controlling
persons to be deemed to protect the Company or any such controlling persons
thereof against any liability to the Distributor to which the Company or any
such controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of reckless disregard of

                                       22
<PAGE>
 
its obligations and duties under this Agreement, or (b) is the Distributor to be
liable under its indemnity agreement contained in this paragraph with respect to
any claim made against the Company or any such controlling persons, unless the
Company or such controlling persons, as the case may be shall have notified the
Distributor in writing within a reasonable time after the summons or other first
legal process giving information of the nature of the claim shall have been
served upon the Company or such controlling persons (or after the Company or
such controlling persons shall have received notice of such service on any
designated agent), but failure to notify the Distributor of any such claim shall
not relieve the Distributor from any liability which the Distributor may have to
the person against whom such action is brought otherwise than on account of the
Distributor indemnity agreement contained in this paragraph. The Distributor
will be entitled to participate at its own expense in the defense, or, if it so
elects, to assume the defense of any suit brought to enforce any such liability,
but if the Distributor elects to assume the defense, such defense shall be
conducted by counsel chosen by it and satisfactory to the Company or such
controlling person or persons, defendant or defendants in the suit. In the event
the Distributor elects to assume the defense of any such suit and retain such
counsel, the Company or such controlling person or persons, defendant or
defendants in the suit, shall bear the fees and expense of any additional
counsel retained by the Company or such controlling

                                       23
<PAGE>
 
person or persons, but, in case the Distributor does not elect to assume the
defense of any such suit, it will reimburse the Company or such controlling
person or persons, defendant or defendants in the suit, for the reasonable fees
and expense of any counsel retained by them. The Distributor shall promptly
notify the Company of the commencement of any litigation or proceedings against
the Distributor or any of its officers, directors, employees or agents in
connection with the issuance or sale of the Contracts or Policies.

                                 INTRODUCTION
                                 ------------



     THIS IS A COMBINATION FIXED AND VARIABLE ANNUITY.  THE CONTRACT HAS TWO
PHASES, THE ACCUMULATION (OR PAY IN) PHASE AND THE DISTRIBUTION (OR PAY OUT)
PHASE.  DURING THE ACCUMULATION PHASE, YOU CONTRIBUTE MONEY WHICH IS CALLED
PREMIUM.  YOUR PREMIUM WILL BE ALLOCATED AND INVESTED AS DIRECTED BY YOU.  IT
CAN BE INVESTED IN EITHER OR BOTH:


          1) AN ACCOUNT WHICH GUARANTEES THE PRINCIPAL AND A FIXED RATE OF
          INTEREST EARNING (THIS IS KNOWN AS THE FIXED FUND ACCOUNT); OR

          2) AN ACCOUNT WHICH DOES NOT GUARANTEE THE PRINCIPAL OR ANY EARNINGS
          (THIS IS KNOWN AS A VARIABLE FUND ACCOUNT). THERE ARE SEVERAL VARIABLE
          FUND ACCOUNTS UNDER THIS CONTRACT WHICH CORRESPOND TO VARIOUS FUNDS OF
          MUTUAL FUNDS IN WHICH YOU MAY CHOOSE TO INVEST. YOUR VALUE IN THE
          VARIABLE FUND ACCOUNTS UNDER THIS CONTRACT WILL VARY WITH THE
          INVESTMENT EXPERIENCE OF THE CORRESPONDING FUND. THE VALUE MAY RISE OR
          IT MAY FALL.


DURING THE ACCUMULATION PHASE, YOU HAVE ACCESS TO THE VALUE IN YOUR CONTRACT,
BUT YOUR INVESTMENT OBJECTIVE IS TO BUILD VALUE FOR RETIREMENT.  AT THE END OF
THE ACCUMULATION PHASE, YOUR CONTRACT VALUE IS APPLIED TO PROVIDE INCOME
PAYMENTS PAID BY THE COMPANY TO THE ANNUITANT.  THE PAYMENTS MAY BE PAID TO THE
ANNUITANT FOR THE REST OF THAT PERSON'S LIFE.  THIS STREAM OF PAYMENTS BY THE
COMPANY IS THE SECOND OR DISTRIBUTION PHASE OF THIS CONTRACT.


     THE DISTRIBUTION YOU SELECT MAY BE A PERIODIC FIXED GUARANTEED PAYMENT
AMOUNT, A PERIODIC VARIABLE NON-GUARANTEED PAYMENT AMOUNT, A COMBINATION OF THE
TWO, OR A LUMP SUM.



                                                                      23979-0797

- --------------------------------------------------------------------------------
                                        
CONTRACT AGREEMENT AND CHANGES

This contract is a legal contract between the Company and the Owner.  The
contract is issued in return for:

  1) Completion of the application; and
  2) Payment of the first premium.

The contract and the application form the entire agreement between you and the
Company.  We will consider statements in the application representations and not
warranties.

Only an officer of the Company has authority to:

  1) Waive a provision of the contract; or
  2) Agree with the Owner to changes in the contract; and then only in writing.

CONTRACT OWNER

The rights and privileges of this contract belong to the Owner during the
Annuitant's lifetime.  The Owner is the Annuitant unless otherwise requested in
the application and we have approved it.  If the Owner and the Annuitant are
different persons and the Owner dies, 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 Owner and dies, then the rights
and privileges of ownership will vest in the Beneficiary.

CHANGE OF OWNERSHIP AND ASSIGNMENT

You may transfer or assign ownership of this contract, subject to any legal
restrictions.  A request to transfer or assign ownership must be made in writing
and be sent to our Service Office.  An assignment is not effective until it is
received by our Service Office.  We are not responsible for determining the
validity of an assignment.

ANNUITANT

The Annuitant is the person who is named to receive income payments and on whose
life expectancy income payments may be based.  The Owner by written request may
change the Annuitant at any time so long as such request is received by our
Service Office at least 15 days before the Annuity Date.  The change will be
effective as of the Date of Receipt of the request.  If the Owner and the
Annuitant are different persons and the Annuitant dies before the Annuity Date,
then the Beneficiary also becomes the Annuitant unless the Owner names a
different Annuitant.

BENEFICIARY

The Beneficiary is the person or persons named in the Application who may be
entitled to receive any contract benefits that are provided upon the Owner's or
the 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, any remaining payments
due will be paid to the Beneficiary's estate.

Unless otherwise provided, benefits will be paid as follows:

       1) If two or more Beneficiaries have been named, all benefits will be
          paid in equal shares to those living at the time of the Annuitant's
          death;

       2) If no Beneficiary survives the Annuitant, payment will be made to the
          Annuitant's estate.


                                                                      23979-0797

CHANGE OF BENEFICIARY

The Owner, during the Annuitant's life, may change the Beneficiary.  To make a
change, written notice must be received by our Service Office.  The change will
take effect as of the date the Owner signs the request.  If we make any payments
before receiving the request to change the Beneficiary, we will receive credit
against our obligations under the contract.

We will not contest this contract from its Effective Date.


MISSTATEMENT OF AGE OR SEX

If the age or sex of the Annuitant has been incorrectly stated, the amount

future annuity distribution payments until the total is repaid.

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


INITIAL PAYMENT

If any part of the initial premium payment is requested to be allocated to the
Fixed Fund Account, it will be allocated to that account on the Effective Date.
If any part of the initial premium payment is requested to be allocated to any
of the Variable Fund Accounts, it will be allocated to the Money Market Variable
Fund Account on the Effective Date.  The premium will remain in the Money Market
Fund Variable Account for the Free Look Period plus five days.  On the Valuation
Date immediately following the end of that period the initial premium payment,
together with any subsequent premium payments that have been made, plus any
earnings will be allocated among the Variable Fund Accounts in the percentages
as directed on the application at the Accumulation Unit value next computed on
that date.  The initial and all subsequent premium payments must be sent to our
Service Office and will not be made effective until received by our Service
Office.

FLEXIBLE PAYMENTS

This is a flexible premium annuity.  Subsequent premium payments may be paid at
any time before the Annuity Date.  The amount of premium may be increased or
decreased.

MINIMUM PAYMENTS


The minimum amount of premium that may be paid and allocated to any account may
not be less than the minimum subsequent premium amount shown on the Contract
Information Page.  Premium payments will be allocated to the Fixed Fund Account
or to one or more of the Variable Fund Accounts as directed by you subject to
the terms of this contract.



PREMIUM PAYMENT ALLOCATIONS


Premium payments that are requested to be allocated among the various accounts
under this contract must be allocated in amounts no smaller than one tenth of a
percent, provided that the total amount equals an aggregate of 100 percent.  The
allocation of subsequent premium payments among the various accounts under this
contract will be made to the same accounts and in the same proportions as the
initial premium payment which is shown on the application.  The allocation of
subsequent premium payments may be changed by the Owner at any time by sending a
written request to our Service Office.  A request to change subsequent premium
payment allocations may be made by telephone if a telephone authorization has
been completed and is on file with our Service Office.  A request to change
subsequent premium payment allocations will be effective with the first premium
payment received on or following the Date of Receipt of the request.



PREMIUM TAX


When premium payments are received, a deduction may be made from the payment if
there is an applicable state premium tax.  The deduction will be the appropriate
amount to cover the premium tax.  The premium tax deduction will be made either
when the premium payment is received by us or when we start annuity payments,
depending on state law.  If a premium tax deduction is not made from a premium
payment and tax is later found to be due, we reserve the right to reduce your
value in the contract to collect the amount of the tax.



DATE SUBSEQUENT PREMIUM PAYMENTS CREDITED


Premium payments after the initial premium payment will be credited to the
accounts under this contract on the Date of Receipt. Payments to the Variable
Fund Accounts under this contract will be credited at the Accumulation Unit
value which is next computed on the Date of Receipt.




                                                                      23979-0797

                               ACCUMULATION PHASE
- --------------------------------------------------------------------------------


INTRODUCTION


During the Accumulation Phase of this contract, your premium payments will be
applied to the Fixed Fund Account or one or more of the Variable Fund Accounts
under this contract as directed by you subject to the terms of this contract.
All premium payments allocated and credited to the accounts under this contract
are net of any applicable premium tax.  Your premium payments will help build
Contract Value.


1. FIXED FUND ACCOUNT


GENERAL DESCRIPTION


Under the Fixed Fund Account of this contract, your premium becomes part of the
Company's general assets and liabilities.  In return, we credit the amount of
the premium payment to your contract and guarantee a fixed rate of interest
earnings.  The premium payment credited to the Fixed Fund Account of this
contract is also guaranteed by the Company and will not fall in value.  The
value of your Fixed Fund Account under this contract on any given date will be:


The sum of premium payments allocated to the Fixed Fund Account:
  (1) less any applicable premium tax;
  (2) plus accumulated interest;
  (3) plus any amounts transferred from the Variable Fund Accounts to the
      Fixed Fund Account;
  (4) less any contract maintenance charge; and
  (5) less any withdrawals or transfers of value that have been made.



CREDITING OF INTEREST


We will credit interest daily on the amount you have in the Fixed Fund Account.
Interest will always be credited at a minimum effective annual rate of 3% or at
a higher rate if required by State law.  Interest credited may be at the
portfolio interest rate or the new money rate depending on when a premium
payment or transfer of value into the Fixed Fund Account is received.

  (a) If received prior to the current calendar year:
             (portfolio interest rate)




                                                                      23979-0797
                                                                      ----------
LVA23979ST 7-94                                                       LVA200S1

                                    Page 13
<PAGE>
 
     At the beginning of each calendar year, we will establish and guarantee an
     interest rate equal to or greater than the minimum rate.  This rate will be
     in effect throughout the calendar year.  We call this our portfolio
     interest rate.  All amounts in the Fixed Fund Account except amounts
     received during the current calendar year will earn interest at this rate.
     Before each month begins, we may at our discretion declare additional
     interest, on all amounts in the Fixed Fund Account except amounts received
     during the current calendar year, for the next month.


     (b) If received during the current calendar year:
               (new money interest rate)


     At the beginning of each calendar month, we will establish and guarantee an
     interest rate equal to or greater than the minimum effective annual rate.
     We call this our new money interest rate.  All premium payments or
     transfers of value into the Fixed Fund Account during a particular month
     will earn interest at the then current new money interest rate through the
     end of the then current calendar year.  At the end of the calendar year,
     all amounts deposited into the Fixed Fund Account during that year become
     subject to our portfolio interest rate and will earn interest thereafter as
     discussed in paragraph (a) above.


WITHDRAWALS


You may at any time during the Accumulation Phase withdraw all or part of your
value in the Fixed Fund Account.  A withdrawal is subject to a withdrawal charge
as described in this contract.  We reserve the right to defer the payment of a
withdrawal from the Fixed Fund Account for up to six months from the date our
Service Office receives the request.



MINIMUM WITHDRAWAL AMOUNT


The minimum amount which may be requested for withdrawal from the Fixed Fund
Account is $500.00, or, if less, the remaining balance of the account.



FREE WITHDRAWAL OR TRANSFER PRIVILEGE


Premium payments that have been made to the Fixed Fund Account more than seven
years prior to the requested date of a withdrawal or transfer from the Fixed
Fund Account may be withdrawn without charge.  In addition, each Contract Year,
the Owner may withdraw or transfer up to 15% of the value of the premium
payments or transfers that have been made to the Fixed Fund Account during the
seven years preceding the requested date of a withdrawal or transfer without
incurring a charge.  All withdrawals or transfers of premium will be considered
made on a "First In-First Out (FIFO)" basis.  If the privilege is not exercised
or is only partially exercised, it cannot be carried over for use in future
Contract Years.


                                                                      23979-0797
                                                                      ----------

WITHDRAWAL OR TRANSFER CHARGES

Except as provided in the Free Withdrawal or Transfer Privilege, a charge will
be deducted from the amount of any premium withdrawn or transferred from the
Fixed Fund Account.  The charge is calculated separately based on the date of
each premium payment or date of transfer into the Fixed Fund Account.  All
premium payments will be considered withdrawn or transferred on a "First In-
First Out (FIFO)" basis.  All withdrawals are considered to be a withdrawal of
premium before any earnings are deemed to be withdrawn.  There is no charge for
withdrawal or transfer of interest earnings.

The charge is calculated as a percentage of the premium withdrawn or
transferred.  This percentage is determined by the number of years between the
date the premium was paid or transferred into the Fixed Fund Account and the
requested date of a withdrawal or transfer as shown in the schedule below.  For
purposes of this charge a year is considered to be a period of 365 days unless a
leap year is involved.

</TABLE>

If value is transferred into the Fixed Fund Account from a Variable Fund
Account, the value is considered a premium payment and is subject to withdrawal
or transfer charges.  The date on which the value was transferred into the Fixed
Fund Account determines whether and how much of a charge is applicable in
accordance with the above schedule.

After the Annuity Date, withdrawals are not available.

INCOME TAX

Withdrawals may be subject to federal income tax penalties.  The Owner should
seek the advice of a tax consultant prior to making a withdrawal.  Under federal
income tax law, all withdrawals for value are treated as withdrawals of interest
earnings before a return of principal.

II. VARIABLE FUND ACCOUNTS

GENERAL DESCRIPTION

During the Accumulation Phase, you may also invest your premium payments in the
Variable Fund Accounts under this contract.  The premium that you allocate to a
Variable Fund Account is invested by the Company through the Separate Account
that we have established to purchase shares of the corresponding Fund at their
Net Asset Value.  Your value in the Variable Fund Accounts will fluctuate and
vary based on the investment experience of the corresponding Fund.


                                                                      23979-0797
                                                                      ----------
LVA23979ST 7-94                                                       LVA200S1

                                    Page 15
<PAGE>
 
THE SEPARATE ACCOUNT

The Separate Account is an investment account established under Texas law
through which USAA Life Insurance Company invests the premium payments received
for investment in the Variable Funds Accounts under this contract.  Through
subdivisions of the Separate Account which are called the Variable Fund Accounts
under this contract, the Company invests in various Funds.  The assets of the
Separate Account are owned by USAA Life Insurance Company and to the extent that
the assets are equal to the reserves and other contractual liabilities, they are
not chargeable with liabilities arising out of any other business of the
Company.  The income, gains, and losses, realized or unrealized, from the assets
of the Separate Account are credited or charged against the Separate Account
without regard to other income, gains or losses of the Company.  The Separate
Account is registered as an investment company under federal securities law.

YOUR VALUE IN VARIABLE FUND ACCOUNTS

At the end of each Valuation Date, the Accumulation Unit value for each Variable
Fund Account is computed.  Your value in a Variable Fund Account is determined
by multiplying the number of Accumulation Units credited to that Variable Fund
Account by the value of the Accumulation Unit as of the end of any Valuation
Date.  Accumulation Units are credited to a Variable Fund Account under this
contract when you pay us premium and allocate it to the particular Variable Fund
Account.  The number of Accumulation Units credited to a Variable Fund Account
under this contract is determined by dividing the premium credited to the
account by the account's Accumulation Unit value next computed on the Date of
Receipt of the premium.  Each Variable Fund Account's Accumulation Units are
valued separately.  Initially, the Accumulation Unit value of each Variable Fund
Account was arbitrarily set at $10.00, except for the Money Market Variable Fund
Account which was set at $1.00.  Thereafter, the Accumulation Unit value of a
Variable Fund Account as of the end of any Valuation Date is calculated as (1)
multiplied by (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 ending on that
          Valuation Date.

NET INVESTMENT FACTOR

The net investment factor is an index number that reflects charges to this
contract and investment performance during a Valuation Period.  The net
investment factor for a Variable Fund Account is determined by dividing (1) by
(2), and then subtracting (3) from the result, where:

      (1) is the net result of:
            (a) the Net Asset Value per share of the Fund shares held in the
                corresponding Variable Fund Account determined at the end of
                the current Valuation Period;

            (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, in any income
                taxes reserved that we determine has resulted from the
                investment operations of the particular Variable Fund Account or
                any other taxes which are applicable to this contract.

      (2) is the Net Asset Value per share of the Fund shares held in the
          corresponding Variable Fund Account determined at the beginning of the
          current Valuation Period.,

      (3) is a factor representing the mortality and expense risk and
          administrative expense charge. The annual charge is 1.15% (1.05% for
          the mortality and expense risk charge and 0.10% for the administrative
          expense charge).




                                                                      23979-0797
                                                                      ----------
LVA23979ST 7-94                                                       LVA200S1

<PAGE>
 
We reserve the right, subject to compliance with federal and state law, to
eliminate any Funds that are made available through this contract and substitute
another Fund if, in our judgment, further investment in the Fund becomes
undesirable in view of the purpose of this contract.  We may add new Variable
Fund Accounts under this contract to permit investment in additional Funds.  We
will give you written notice of the addition, elimination and substitution of
any Fund within five days after such action occurs.

Your value in a Variable Fund Account is also reduced by any values you have
withdrawn or transferred, the contract maintenance charge and any charges that
may be levied if systematic withdrawals are elected.  You may learn what the
daily value of an Accumulation Unit is and the number of units credited to the
Variable Fund Accounts under your contract by contacting our Service Office.


VOTING RIGHTS

You have voting rights in relation to your value maintained in the Variable Fund
Accounts.  You do not have voting rights in relation to value maintained in the
Fixed Fund Account or in relation to Fixed Annuity payments.

We will vote shares of the underlying Funds in which the Variable Fund Accounts
invest in the manner directed by Owners.  Owners may give instructions equal to
the number of shares represented by the Units attributable to their Variable
Fund Accounts.

We will vote the shares attributable to assets held in the Separate Account
solely for us rather than on behalf of Owners, or any shares as to which we have
not received instructions, in the same manner and proportion as the shares for
which we have received instructions.  We will do so separately for each Fund
that corresponds to a Variable Fund Account.  If we determine, based on our
interpretation of applicable law, that we are permitted to vote any fund shares
in our own right, we may elect to do so.

The number of votes for an underlying Fund will be determined as of the record
date for such Fund as chosen by its board of trustees or board of directors.  We
will furnish Owners with proper forms and proxies to enable them to instruct us
how to vote.

You may instruct us how to vote on the following matters:  (a) election of the
board of trustees or board of directors, as applicable;  (b) ratification of the
independent auditing firm;  (c) approval of the investment advisory agreement;
(d) any change in the fundamental policy; and (e) any other matter requiring a
vote of the shareholders.

With respect to approval of the investment advisory agreement or any change in
fundamental investment policy, only Owners maintaining value as of the record
date in a Variable Fund Account that corresponds to the particular Fund may
instruct us how to vote on the matter, pursuant to the requirements of federal
law.

WITHDRAWALS

You may at any time during the Accumulation Phase withdraw all or part of your
value in a Variable Fund Account. A withdrawal from a Variable Fund Account is
not subject to any charge, except a tax charge if applicable.  A withdrawal will
be made effective at the Accumulation Unit Value next computed on the Date of
Receipt of the request.  Unless requested differently by the Owner, the value
surrendered will be withdrawn from the Variable Fund Accounts in the same
proportion as each account's value has to the total value of all the Variable
Fund Accounts under the contract as of the Date of Receipt of the request.
Requests for withdrawals of value will be paid within seven days of receipt of
the request by our Service Office, except as provided under "Postponement of
Payments" on page 26.

WITHDRAWAL OR TRANSFER CHARGES

There is no charge for a withdrawal or transfer of value from a Variable Fund
Account.

MINIMUM WITHDRAWAL AMOUNT

The minimum amount which may be requested for withdrawal from a Variable Fund
Account is $500.00, or, if less, the remaining balance of the account.

INCOME TAX

Withdrawals may be subject to federal income tax penalties.  The Owner should

III. MISCELLANEOUS PROVISIONS

CONTRACT VALUE

The Contract Value as of any date during the Accumulation Phase will be:

     The sum of Premium Payments:

        (1) Less any applicable premium tax;

        (2) Plus interest credited to the Fixed Fund Account;

        (3) Plus any increase or less any decrease in the value of the
            Variable Fund Accounts;

        (4) Less any contract maintenance charge;

        (5) Less any withdrawals of value or loans of value (if allowed by
            endorsement) that have been made.

MINIMUM REQUIRED CONTRACT VALUE

If during the Accumulation Phase the Contract Value is less than the minimum
required Contract Value as shown on the Contract Information Page and no premium
payments have been received by us for a period of two years, we may at our
option cancel this contract.  We will give the Owner 30 days' written notice and
an opportunity to satisfy this requirement before we cancel the contract.  In
the event of a cancellation, we will pay the Owner the Contract Value in a lump
sum and be released of any further obligations under the contract.

TRANSFERS

You may convey value from one account to another account under this contract.
This is known as a transfer.  There is no charge for a transfer from a Variable
Fund Account.  Transfers from the Fixed Fund Account may be subject to charges.
Transfers are also subject to the following restrictions:

    (1) Only six transfers may be made each Contract Year;

    (2) The minimum amount that may be transferred from an account is $100.00;

    (3) A request for a transfer must clearly state the amount to be
        transferred, the account from which it is to be withdrawn, and the
        account to which it is to be credited;

    (4) A transfer may not be made during the first 30 days after the
        Effective Date;


                                                                      23979-0797
                                                                      ----------
LVA23979ST 7-94                                                       LVA200S1

                                    Page 18
<PAGE>
 
    (5) A transfer will result in either the redemption or purchase of
        Accumulation Units, or both; the transfer will be processed effective at
        the Accumulation Unit Value next computed on the Date of Receipt of the
        transfer request;

    (6) We reserve the right at any time and without prior notice to terminate,
        suspend, or modify these transfer privileges.


DOLLAR COST AVERAGING


We offer dollar cost averaging in the Accumulation Phase.  There is no charge
for this service and it does not count toward your limit of six transfers per
Contract Year.  Dollar cost averaging is a program designed to provide for
regular, approximately equal investments over time.  You may choose to transfer
a fixed dollar amount or a specified percentage at regular intervals from any of
the Variable Fund Accounts under this contract to one or more of the other
accounts under this contract.  Dollar cost averaging is not permitted out of the
Fixed Fund Account.  Transfers under a program of dollar cost averaging will be
processed effective at the Accumulation Unit value at the end of the Valuation
Period that includes the date of transfer.


You must have at least $5,000.00, of value in an account to begin a program of
dollar cost averaging from that account.  The minimum amount that may be
transferred from an account to another account is $100.00, or, if less, the
remaining balance of the account.  The intervals between transfers may be
monthly, quarterly, or semi-annually.  The transfers must be scheduled to occur
over a period of at least 12 months.  You may select this program by making a
request in writing or by telephone if a telephone authorization has been
completed and is on file.  You may cancel your participation in this program in
the same manner.  We reserve the right to terminate, suspend or modify the
offering of this dollar cost averaging service upon providing you written notice
30 days in advance.  Should we suspend or cancel this service, the suspension or
cancellation will not affect any dollar cost averaging program then in effect.


SYSTEMATIC WITHDRAWALS


We offer a program of systematic withdrawals.  Payments may be made annually,
semi-annually, quarterly, or monthly.  Withdrawals will be processed effective
at the Accumulation Unit value at the end of the Valuation Period that includes
the date of withdrawal.  Withdrawals may be made pro rata from all accounts
under this contract or the Owner may specify which account(s) the payment is to
be taken from.  Systematic withdrawals from the Fixed Fund Account are subject
to a withdrawal charge if they are in excess of the free withdrawal or transfer
privilege.  We reserve the right to charge a fee if this program is selected.
We also reserve the right to terminate, suspend or modify this program upon
providing you written notice 30 days in advance.  Should we terminate, suspend
or modify this program, the suspension or cancellation will not affect any
systematic withdrawal program then in effect.


The minimum amount of Contract Value you must have to begin a systematic
withdrawal program is $20,000.00.  The minimum amount that can be withdrawn from
an account under this program is $250.00, or, if less, the remaining balance of
the account.  You may change the amount or frequency of the systematic
withdrawal once in each Contract Year.


Systematic withdrawals may be subject to federal income tax and penalties.  The
Owner should seek the advice of a tax consultant prior to selecting a program of
systematic withdrawal.

DEATH BENEFIT

If the Annuitant is the Owner and dies before the Annuity Date, we will pay the
Beneficiary a death benefit.  If the Owner is not the Annuitant and the Owner
dies before the Annuity Date, we will pay a death benefit to the Annuitant, or
the Beneficiary if the Annuitant does not survive the Owner.  We must receive
proof of death and a written request, satisfactory to us in form and content,
choosing the manner of payment before the death benefit will be paid.  Proof of
death shall be either a certificate of death, a certified copy of a statement of
death from the attending physician, a certified copy of a decree of a court of
competent jurisdiction as to the finding of death, or any proof satisfactory to
us.  The death benefit is the greater of:

   (1) the Contract Value on the date we receive proof of death; or
   (2) the sum of the premium payments credited to this contract, less the
       amount of any withdrawals and less any applicable premium tax.

In lieu of receiving the death benefit in a lump sum the Beneficiary or the
Annuitant, if entitled, may choose a Distribution Option subject to the
following distribution requirements.

DISTRIBUTION REQUIREMENTS

In accordance with current federal income tax law, if the Owner dies before the
Annuity Date, distribution of the Contract Value is required to be as follows:

      (1) If the Owner and Annuitant are the same person and no Beneficiary
          was designated or survived the Owner, full distribution to the Owner's
          estate must occur within five years after the Owner's death should be;

      (2) If the Owner and the Annuitant are the same person and the
          Beneficiary is the Owner's spouse, or if the Annuitant is the Owner's
          spouse, the spouse may:

             (a) Assume ownership as the Annuitant and defer distribution
                 until the Annuity Date; or

             (b) Receive distributions over a period of time not exceeding the
                 spouse's life expectancy and distribution must begin within one
                 year after the Owner's death;

      (3) If the Owner and the Annuitant are the same person and the
          Beneficiary is not the Owner's spouse, then distribution must begin
          within one year after the Owner's death and must be made over a period
          of time not exceeding the life expectancy of the Beneficiary;

      (4) If the Owner and the Annuitant are not the same person and the 
          Annuitant is not the Owner's spouse, then distribution must begin
          within one year after the Owner's death and must be made over a period
          of time not exceeding the life expectancy of the Annuitant, or
          Beneficiary if the Annuitant does not survive the Owner.

CONTRACT MAINTENANCE CHARGE


Beginning on the anniversary of the Effective Date, and each anniversary
thereafter, we will deduct a charge of $30.00 from the Contract Value for
contract maintenance.  If the total Contract Value is withdrawn at any time
during a Contract Year, this charge will be deducted from the Contract Value on
the date of the withdrawal.  The deduction will be made only while the contract
is in the Accumulation Phase.  We will prorate the charge among all of the
accounts under this contract.  The charge to an account will be in the same
proportion as each account's value has to the Contract Value as of the
anniversary or as of the date of a total withdrawal.  Any charge to the Fixed
Fund Account will be waived to the extent it would cause the amount of interest
earned from the last contract anniversary to be less than 3%.


MORTALITY AND EXPENSE RISK CHARGE


The mortality and expense risk charge is a charge that applies only to the
Variable Fund Accounts under this contract.  The charge is assessed on a daily
basis and affects the value of the Accumulation Unit or Annuity Unit of each
Variable Fund Account under this contract.  This charge is equal, on an annual
basis, to 1.05% of the average net assets of each Variable Fund Account.  This
charge compensates us for assuming the mortality and expense risks under this
contract.


ADMINISTRATIVE EXPENSE CHARGE


The administrative expense charge is a charge that applies only to the Variable
Fund Account under this contract.  The charge is assessed on a daily basis and
affects the value of the Accumulation Unit or Annuity Unit of each Variable Fund
Account under this contract.  This charge is equal, on an annual basis, to 0.10%
of the average net assets of each Variable Fund Account.  The administrative
expense charge together with the contract maintenance charge compensates us for
the expense we incur in the establishment and maintenance of this contract.


TAX CHARGE


The company reserves 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.  The charge if assessed will be applied on a pro
rata basis to determine the Accumulation Unit value or Annuity Unit value.

A charge may also be assessed if there is an applicable state premium tax.  See
page 12 for an explanation of the application of state premium tax.


WITHDRAWAL OR TRANSFER CHARGE


A withdrawal or transfer charge may be assessed in some instances against
amounts that are withdrawn or transferred from the Fixed Fund Account.  See page
14 for an explanation of when these charges may be applicable.


                                                                      23979-0797

                               DISTRIBUTION PHASE
- --------------------------------------------------------------------------------

INTRODUCTION

On the Annuity Date, the Company begins making income payments to the Annuitant
pursuant to the distribution option you select.  We will continue to make
payments to the Annuitant as provided by the Distribution Option selected.
These payments may be made over the lifetime of the Annuitant.  The period of
time during which these payments are made is known as the Distribution Phase of
this contract.


ANNUITY DATE

The Annuity Date is the date chosen by the Owner.  If this contract is used as a
Qualified Plan, it must not be later than the date required by federal income
tax law.  If this contract is used as a Nonqualified Plan, it may not be later
than the Annuitant's 95/th/ birthday.  The Annuity Date must be at least six
months after the Effective Date, unless we choose to waive this requirement.
You may change the Annuity Date selected by giving written notice to our Service
Office.  Notice must be received by our Service Office at least 30 days prior to
the Annuity Date.


MINIMUM CONTRACT VALUE FOR DISTRIBUTION OPTIONS

If at the time this contract becomes payable the Contract Value is less than
$2,000.00 or would provide a monthly distribution payment of less than $20.00
per month, we may at our option cancel this contract.  In this event, we will
pay the Annuitant the Contract Value in a lump sum and be released of any
further obligations under the contract.


ELECTION OF DISTRIBUTION OPTION AND FIXED OR VARIABLE ANNUITY PAYMENTS

At least 30 days prior to the Annuity Date, you must inform us in writing which
one of the Distribution Options described on page 24-25 you want to use to begin
distribution payments.  You must also notify us in writing whether you want your
Contract Value to fund systematic withdrawals, a Fixed Annuity and/or a Variable
Annuity.  Variable Annuity payments can be allocated form a maximum of four
Variable Fund Accounts.  The Contract Value or portion thereof will then be
applied to determine the amount of the distribution payment.  If this contract
has been assigned, the amount due the assignee must be paid in a lump sum before
any distribution payments can be determined and commenced.

If you have not elected a Distribution Option at least 30 days prior to the
Annuity Date, we will apply the Contract Value to effect an annuity under Option
2 as described on page 25 with monthly payments guaranteed for 10 years.  The
value of the Fixed Fund Account will be applied to effect a Fixed Annuity.  The
value of the Variable Fund Accounts will be applied to effect a Variable Annuity
with payments funded from each Variable Fund Account in the same proportion as
each account's value has to the total value of all Variable Fund Accounts under
your contract.

In electing a Distribution Option, you may apply all of your Contract Value to
effect a Fixed Annuity or a Variable Annuity.  You may allocate Contract Value
to effect a combination Fixed and Variable Annuity.  You may also obtain
distribution payments by systematic withdrawal.


                                                                      23979-0797

LVA23979ST 7-94                                                       LVA200S1

                                    Page 22

FIXED ANNUITY DISTRIBUTION

A Fixed Annuity provides a distribution under which payments do not vary as to
dollar amount and which are guaranteed by the Company.  The guaranteed monthly
payment amount for each $1,000.00 of Contract Value applied is shown in the
appropriate Annuity Payment Table beginning on page 26.


VARIABLE ANNUITY DISTRIBUTION

A Variable Annuity provides payments that are not guaranteed.  The amount of the
payment will vary based on the investment experience of the Funds that
correspond to the Variable Fund Accounts under this contract.  The amount of the
payment may rise or it may fall.  We guarantee that the dollar amount of each
payment after the first shall not be affected by actual expenses or variations
in mortality experience.


DETERMINATION OF THE FIRST VARIABLE ANNUITY DISTRIBUTION PAYMENT

If a Variable Annuity distribution is selected, value will be applied in
accordance with the Distribution Option selected.  The amount of the first
payment for each $1,000.00 of value applied is shown in the appropriate Annuity
Payment Table beginning on page 27.


DETERMINATION OF VARIABLE ANNUITY DISTRIBUTION PAYMENTS AFTER THE FIRST PAYMENT

Each Variable Fund Account has Annuity Units, the value of which fluctuates and
varies daily.  The dollar amount of the first annuity payment for each Variable
Fund Account is divided by the value of that account's Annuity Unit as of the
end of the Valuation Period immediately preceding the tenth day before the
Annuity Date.  This result establishes a fixed number of Annuity Units for each
Variable Fund Account under this contract.  The number of Annuity Units under
each Variable Fund Account is then used to determine the amount of each periodic
annuity payment to be made from that account.

The number of Annuity Units in a Variable Fund Account is multiplied by the
Annuity Unit value of that account as of the end of the Valuation Period
immediately preceding the tenth day before the date on which payment is to be
made.  This result establishes the dollar amount of the payment from that
account.  The payments from each Variable Fund Account are then added to
determine the total Variable Annuity payment to be made to the Annuitant.


ANNUITY UNIT VALUE

At the end of each Valuation Date, the Annuity Unit value for each Variable Fund
Account is computed.  Initially, the Annuity Unit value for each Variable Fund
Account was arbitrarily set at $10.00 except for the Money Market Variable Fund
Account which was set at $1.00.  Thereafter, the Annuity Unit value of a
Variable Fund Account as of the end of any Valuation Date is calculated by
multiplying (1) by (2) and multiplying the result by (3) where:

      (1) Is the Annuity Unit value for the Variable Fund Account as of the
          end of the immediately preceding Valuation Period; and

      (2) Is the Net Investment Factor, as defined on page 15, for the
          Valuation Period then ended; and

      (3) Is a factor used to adjust for the assumed interest rate of 3% per
          year used in the Tables but which is not applicable because the actual
          amount earned on the Variable Fund Account is credited instead.


                                                                      23979-0797
                                                                      ----------
LVA23979ST 7-94                                                       LVA200S1

                                    Page 23
<PAGE>
 
TRANSFERS OF ANNUITY UNITS

You may transfer Annuity Units by filing a written request with our Service
Office, or you may request a transfer by telephone if a telephone authorization
has been completed and is on file with our Service Office.

Values may be transferred between the Variable Fund Accounts.  The total amount
transferred from an account must be at least $100.00.  You may also transfer
Annuity Units from a Variable Fund Account to establish a Fixed Annuity payout
or increase the amount of Fixed Annuity payments.  Transfers of value from a
Variable Fund Account to another Variable Fund Account or to a Fixed Annuity are
limited to three per Contract Year during the Distribution Phase.  There is no
charge for such transfers.

Transfers will be processed effective at the Annuity Unit value next computed on
the Date of Receipt of the transfer request.

If a request to transfer Annuity Units is received after the Valuation Period
that immediately precedes the tenth day before an annuity payment date, the
transfer will be effective at the Annuity Unit value next computed on the
Valuation Date immediately following the annuity payment date.  Once Annuity
Unit value has been transferred to purchase a Fixed Annuity payment or to
purchase or to purchase a larger Fixed Annuity payment, it is locked in and
cannot be transferred out.


OWNER/ANNUITANT'S DEATH

In accordance with current federal income tax law, if the Owner is the Annuitant
and dies on or after the Annuity Date, any payments that remain under the terms
of the contract must continue at least as rapidly as before the Annuitant's
death.  The Beneficiary may:

      (1) Continue to receive the same payments as the Annuitant; or

      (2) Receive higher payments, but over a shorter period of time, than the
          Annuitant was receiving; or

      (3) Take full distribution of the remaining value at the Annuitant's
          death.

If payments were contingent upon the Annuitant being alive, then these
distribution rules do not apply.


- --------------------------------------------------------------------------------
                              DISTRIBUTION OPTIONS
- --------------------------------------------------------------------------------

GENERAL

You may elect to have payments made under any one or more of the Distribution
Options listed below or any other option including a lump sum that you and the
Company mutually agree upon in writing.  Payments may be received on a Fixed
Annuity basis, a Variable Annuity basis, or both, or by systematic withdrawal.
Payments on a Fixed Annuity basis are available under Options 1 through 5.
Payments on a Variable Annuity basis are available only under Option 1, 2 and 3.
Regardless of whether a Fixed Annuity or Variable Annuity is selected, if Option
1 or 3 is chosen it is possible to receive only one payment if the Annuitant or
the Joint Annuitants die before the second payment.  This is possible because no
minimum number of payments is guaranteed by the Company under those Options.



                                                                      23979-0797
                                                                      ----------
LVA23979ST 7-94                                                       LVA200S1

The attached tables show the minimum dollar amount of the first monthly payment
for each $1,000.00 applied under the Distribution Options.  The tables are based
on an assumed investment rate of 3%.  The Company may, at its discretion, offer
more favorable Distribution Option values based upon its then current interest
rate and mortality assumptions.


OPTION 1.  INCOME PAYMENTS FOR LIFE  -  If a Fixed Annuity is selected under
this option, the Company guarantees periodic payments as long as the Annuitant
is alive.  If monthly payments are selected, they are made at the values shown
in Table 1.

If a Variable Annuity is selected under this option, periodic payments are
designed to continue as long as the Annuitant is alive, but because of the
inherent risk of a market based investment are not guaranteed to continue for
life.  If monthly payments are selected, the first payment is made at the values
shown in Table 1.  Subsequent Variable Annuity payments are variable in dollar
amount.


OPTION 2.  INCOME PAYMENTS FOR LIFE WITH A CERTAIN PERIOD GUARANTEED  -  If a
Fixed Annuity is selected under this option, the Company guarantees periodic
payments will be made as long as the Annuitant is alive.  The Company also
guarantees that periodic payments will be made for a certain period of time even
if the Annuitant dies before that period of time has expired.  If monthly
payments are selected, they are made at the value shown in Table 1.

If a Variable Annuity is selected under this option, periodic payments are
designed to continue as long as the Annuitant is alive, but because of the
inherent risk of a market based investment are not guaranteed to continue for
life.  Under this option the Company will make payments for a certain period of
time even if the Annuitant dies before that period of time has expired.  The
amount of the payment is, however, contingent upon the current value of the
Annuity Units at the time the payment is due.

If monthly payments are selected, the first payment is made at the values shown
in Table 1.  Subsequent Variable Annuity payments are variable in dollar amount.


OPTION 3.  JOINT AND SURVIVOR LIFE INCOME  -  If a Fixed Annuity is selected
under this option, the Company guarantees periodic payments as long as the
Annuitant or the Joint Annuitant is alive.  If monthly payments are selected,
they are made at the value shown in Table 2.

If a Variable Annuity is selected under this option, periodic payments are
designed to continue as long as the Annuitant or the Joint Annuitant is alive,
but because of the inherent risk of a market based investment are not guaranteed
to continue for their lives.  If monthly payments are selected, the first
payment is made at the values shown in Table 2.  Subsequent Variable Annuity
payments are variable in dollar amount.

If one of the joint annuitants dies before the Annuity Date the election of this
option is revoked.  The surviving Annuitant may elect to receive any one or more
of the other Distribution Options available under the contract.


OPTION 4.  INCOME FOR SPECIFIED PERIOD  -  If distribution is selected under
this option, the Company will make periodic payments which are guaranteed for a
specified period of time.  This period of time is agreed upon before payments
begin.  This period of time cannot be longer than 30 years.  If monthly payments
are selected, they are made at the values shown in Table 3.


OPTION 5.  INCOME OF FIXED AMOUNT  -  If distribution is selected under this
option, a sum of monetary value is transferred to the Company.  In exchange, the
Company agrees to pay the specified amount of interest on the principal and to
make periodic payments of a fixed dollar amount that is chosen as long as the
principal and interest earnings last.  If monthly payments are selected, they
are made at the values shown in Table 3, but the number of years payable depends
on the sum of monetary value transferred to the Company.


                                                                      23979-0797
                                                                      ----------

                                    Page 25
<PAGE>
 
OPTION 6.  SYSTEMATIC WITHDRAWALS  -  You may elect a series of substantially
equal periodic payments made either monthly, quarterly, semi-annually or
annually.  These payments may be made over the life expectancy of the Annuitant
or over a shorter period of time.  Withdrawals will be processed effective at
the Accumulation Unit value at the end of the Valuation Period that includes the
date of withdrawal.  Withdrawals may be made pro rata from all accounts under
this contract or the Owner may specify which account(s) the payment is to be
taken from.  You may change the amount or frequency of the systematic withdrawal
once in each Contract Year.  The minimum amount of Contract Value you must have
to elect systematic withdrawal is $20,000.00.  The minimum amount that can be
withdrawn from an account under this contract is $250.00, or, if less, the
remaining balance of the account.

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

                            POSTPONEMENT OF PAYMENTS
- --------------------------------------------------------------------------------

We may not be able to determine the value of assets of the Variable Fund
Accounts if:

      (1) The New York Stock Exchange is closed for other than customary
          weekends and holidays; or

      (2) Trading on the New York Stock Exchange is restricted; or

      (3) An emergency exists as a result of which it is not reasonably
          practicable to dispose of securities held in the Separate Account or
          determine their value; or

      (4) The Securities and Exchange Commission, by order, permits us to
          defer payments for the protection of Owners of our Variable Annuity
          contract.

During such times we may defer:

      (1) Determination of Variable Fund Account values;

      (2) Payment of such values; and

      (3) Any requested transfer of Variable Fund Account values.

Requests for partial or full withdrawals which would be derived from a premium
payment made to us by a check which has not cleared the banking system will be
deferred until payment of the check has been honored, to the extent permitted by

                   INDIVIDUAL RETIREMENT ANNUITY (IRA) RIDER
                          USAA LIFE INSURANCE COMPANY


     This rider amends and becomes a part of the annuity contract to which it is
attached (hereinafter called "this contract") and has the same effective date as
the annuity contract.  This contract is for the exclusive benefit of the
Annuitant or his/her beneficiary.  The Annuitant and Owner shall always be the
same person.  The Annuitant hereby agrees that as of the effective date, this
contract shall be modified in the following particulars:

      (1) A contract issued on the basis of this application will not be
          transferable except to the Company on surrender or settlement or under
          a Qualified Domestic Relations Order issued by a court having
          appropriate jurisdiction. It may not be sold, assigned, discounted or
          pledged as collateral for a loan or as security for the performance of
          an obligation or any other purpose. The entire interest of the
          Annuitant in this contract shall be nonforfeitable.

      (2) The annual contribution under this contract will not be fixed and
          will not exceed the lesser of 100% of the Annuitant's compensation for
          the taxable year or $2,000 for any Annuitant, except that this $2,000
          limitation is not applicable to:

             a. A single premium payment which represents any portion of an 
                eligible rollover distribution as defined and described in
                sections 402(c)(4), 403(a)(4), 403(b)(8) or 408(d)3 of the
                Internal Revenue Code; or

             b. Premiums which represent contributions under sections 408(j),
                (k) or (l) of the Internal Revenue Code.

     Compensation means wages, salaries, professional fees, or other amounts
derived from or received for personal services actually rendered (including, but
not limited to commissions paid salespersons, compensation for services on the
basis of a percentage of profits, commissions on insurance premiums, tips, and
bonuses) and includes earned income, as defined in section 401(c)(2) (reduced by
the deduction the self-employed individual takes for contributions made to a
self-employed retirement plan).  For purposes of this definition, section
                                 ----------------------------------------
401(c)(2) shall be applied as if the term trade or business for purposes of
- ---------------------------------------------------------------------------
section 1402 included service described in subsection (c)(6).  Compensation does
- ------------------------------------------------------------                    
not include amounts derived from or received as earnings or profits from
property (including but not limited to interest and dividends) or amounts not
includible in gross income.  Compensation also does not include any amount
received as a pension or annuity or as deferred compensation.  The term
"compensation" shall include any amount includible in the individual's gross
income under section 71 with respect to a divorce or separation instrument
described in subparagraph (A) of section 71(b)(2).

     Contributions will be in cash only.  Any refund of premiums (other than
those attributable to excess contributions) will be applied before the close of
the calendar year following the year of the refund toward the payment of future
premiums or the purchase of additional benefits.

      3. If premium payments are interrupted, the contract will not terminate
         except as provided in the contract section titled Minimum Required
         Contract Value, and premium payments of at least the minimum amount
         shown on the Contract Information Page may be resumed at any time.

      4. The entire value of the Annuitant's contract will be distributed, or 
         commence to be distributed, no later than the first day of April
         following the calendar year in which the Annuitant attains. Age 70 1/2,
         in equal or substantially equal amounts, over (a) the Annuitant's life
         or the lives of the Annuitant and his/her designated beneficiary, or
         (b) a period certain not extending beyond the Annuitant's life
         expectancy or the joint and last survivor expectancy of the Annuitant
         and his/her designated beneficiary.

                                                                      ----------
LQA24882ST 11-97                                                      AQA309ST

      5. Minimum Amounts To Be Distributed.  If the Annuitant's entire interest
         is to be distributed in other than a lump sum, then the amount to be
         distributed each year (commencing with the required beginning date and
         each year thereafter) must be at least equal to the quotient obtained
         by dividing the Annuitants benefit by the applicable life expectancy.

         For calendar years beginning after December 31, 1988, the amount to be
         distributed each year, beginning with the first calendar year for which
         distributions are required and then for each succeeding calendar year,
         shall not be less than the quotient obtained by dividing the
         Annuitant's benefit by the lesser of (1) the applicable life expectancy
         or (2) if the Annuitant's spouse is not the designated beneficiary, the
         applicable divisor determined from the table set forth in Q&A-4 of
         section 1.401(a)(9)-2 of the Proposed Income Tax Regulations.
         Distributions after the death of the Annuitant shall be distributed
         using the applicable life expectancy as the relevant divisor without
         regard to proposed regulations section 1.401(a)(9)-2.

         Life expectancy is computed by use of the expected return multiples in
         Tables V and VI of section 1.72-9 of the Income Tax Regulations. Unless
         otherwise elected by the participant by the time distributions are
         required to begin, life expectancies shall be recalculated annually.
         Such election shall be irrevocable as to the participant and shall
         apply to all subsequent years. The life expectancy of a non-spouse
         beneficiary may not be recalculated. Instead, life expectancy will be
         calculated using the attained age of such beneficiary during the
         calendar year in which distributions are required to begin pursuant to
         this section, and payments for subsequent years shall be calculated
         based on such life expectancy reduced by one for each calendar year
         which has elapsed since the calendar year life expectancy was first
         calculated.

         Distributions under this annuity contract shall be made in accordance
         with the requirements of section 401(a)(9) of the Code and the
         Regulations thereunder. For purposes of this requirement, any amount
         paid to a child of the Annuitant will be a treated as if it had been
         paid to the surviving spouse if the remainder of the interest becomes
         payable to the surviving spouse when the child reaches the age of
         majority.

      6. Before distributing an amount from the contract, the Company shall
         receive from the Annuitant a declaration in writing of the Annuitant's
         intention as to the disposition of the amount distributed, except in
         the case of the Annuitant's death or disability or when the Annuitant
         is at least age 59 1/2. Distributions paid during the Annuitant's
         lifetime other than periodic payments are subject to contractual
         surrender charges, regardless of the Annuitant's age.

      7. Distributions Beginning Before Death.  If the Annuitant dies after
         distribution of his/her interest has begin, the remaining portion of
         such interest will continue to be distributed at least as rapidly as
         under the method of distribution being used prior to the Annuitant's
         death.

      8. Distributions Beginning After Death.  If the Annuitant dies before
         distribution of his/her interest begins, the Annuitant's entire
         interest will be distributed in accordance with one of the following
         four provisions:

            a. The Annuitant's entire interest will be paid by December 31 of
               the calendar year containing the fifth anniversary of the
               Annuitant's death.

            b. If the Annuitant's interest is payable to a beneficiary
               designated by the Annuitant and the Annuitant has not elected
               (8)(a) above, then the entire interest will be distributed over
               the life or over a period certain not greater than the life
               expectancy of the designated beneficiary commencing on or before
               December 31 of the calendar year immediately following the
               calendar year in which the Annuitant died. The designated
               beneficiary may elect at any time to receive greater payments.

                                    Page 2                            24882-1297
                                                                      ----------
LQA24882ST 11-97                                                      AQA309ST
<PAGE>
 
      c. If the designated beneficiary of the Annuitant is the Annuitant's
         surviving spouse, the spouse may elect to receive equal or
         substantially equal payments over the life or life expectancy of the
         surviving spouse commencing at any date prior to the later of (1)
         December 31 of the calendar year immediately following the calendar
         year in which the Annuitant died and (2) December 31 of the calendar
         year in which the Annuitant would have attained age 70 1/2. Such
         election must be made not later than the earlier of December 31 of the
         calendar year containing the fifth anniversary of the Annuitant's death
         or the date distributions are required to begin pursuant to the
         preceding sentence. The surviving spouse may increase the frequency or
         amount of such payments.

      d. If the designated beneficiary is the Annuitant's surviving spouse, the
         spouse may treat the contract as his/her own Individual Retirement
         Arrangement (IRA). This election will be deemed to have been made if
         such surviving spouse makes a regular IRA contribution to or a rollover
         to or from such contract, or fails to elect any of the above three
         provisions.

AMENDMENT OF CONTRACT TO QUALIFY AS ROTH INDIVIDUAL RETIREMENT ANNUITY ("ROTH
IRA") UNDER SECTION 408A OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED
("CODE") -SECTIONS 9 AND 10 APPLY IF THE ANNUITANT HAS DESIGNATED THIS CONTRACT
AS A ROTH IRA.

 9. The contract will accept contributions only as follows:

      a. Contributions to this contract must be paid in cash and, except in
         the case of a trust-to-trustee transfer from another Roth IRA, or in
         the case of a conversion from a Traditional IRA to a Roth IRA, may not
         exceed the excess of the Owner's contribution limit for the taxable
         year over the aggregate contributions made during the taxable year to
         all other Roth IRAs and Traditional IRAs held by the Owner.
         Contributions may be made without respect to the age of the Owner.

      The contribution limit for the taxable year is either (1) the lesser of
         $2,000 or 100% of compensation of the Owner for the taxable year, or
         (2) where the Owner files a joint return and receives less compensation
         for the taxable year than the Owner's spouse, the lesser of $2,000 or
         100% of the compensation of the Owner and the Owner's spouse for the
         taxable year less the spouse's contribution to a Roth IRA or
         Traditional IRA for the taxable year (if any).

         For single taxpayers, contributions to a Roth IRA are phased out
         pursuant to provisions of the Internal Revenue Code for adjusted gross
         incomes between $95,000 and $110,000. For joint taxpayers,
         contributions to the Roth IRA are phased out pursuant to the provisions
         of the Internal Revenue Code for adjusted gross income between $150,000
         and $160,000.

      b. A conversion can be made from a traditional IRA to a Roth IRA only if
         the Owner's adjusted gross income for the taxable year of the
         conversion does not exceed $100,000.

      c. For purposes of this section, compensation means wages, salaries,
         professional fees, or other amounts derived from or received for
         personal service actually rendered and includes earned income, as
         defined in section 401(c)(2) (reduced by the deduction the self-
         employed individual takes for contributions made to a self-employed
         retirement plan). Compensation does not include amounts derived from or
         received as earnings or profits from property (including, but not
         limited to, interest and dividends) or amounts not includible in gross
         income. Compensation also does not include any amount received as a
         pension or annuity or as deferred compensation. The term "compensation"
         shall include any amount includible in the Owner's gross income under
         section 71 with respect to a divorce or separation instrument described
         in subparagraph (A) of section 71(b)(2).


 10. The Owner's entire interest will be distributed in accordance with one of
     the following four provisions:

      a. The Owner's entire interest will be paid by December 31 of the
         calendar year which contains the fifth anniversary of the Owner's
         death.

      b. If any portion of the Owner's interest is payable to a designated
         beneficiary and such beneficiary has not elected (a) above, then the
         entire interest which is payable to the beneficiary will be distributed
         in substantially equal installments over a period not exceeding the
         life or life expectancy of the designated beneficiary, commencing by
         December 31 following the first anniversary of the Owner's


                                    Page 3                            24882-1297
                                                                      ----------
LQA24882ST 11-97                                                      AQA309ST

          death. The designated beneficiary may elect at any time to receive
          greater payments if otherwise permitted under the terms of the
          contract.

       c. In applying the requirements of (b) to any portion of the Owner's
          interest which is payable to the Owner's surviving spouse, the date on
          which the Owner would have attained age 70 1/2 will be substituted for
          the first anniversary of the Owner's death.

       d. If the designated beneficiary of the Owner is the Owner's surviving
          spouse, the spouse may treat the contract as the spouse's own Roth
          IRA. This election will be deemed to have been made if the surviving
          spouse makes a rollover or other contribution into this contract or if
          the surviving spouse has failed to satisfy one or more requirements
          described in (a) or (b). If the Owner's surviving spouse dies before
          distributions are required to begin under this section, the Owner's
          surviving spouse will be treated as having elected to make the Roth
          IRA his or her own Roth IRA.

 11. This contract shall be amended from time to time if required to reflect
     changes in the Internal Revenue Code, Internal Revenue Service Regulations,
     or published revenue rulings.

     It is hereby agreed that it is the responsibility of the Annuitant to
     notify the Company in the event that the aggregate contributions due or
     paid under all accounts or contracts purchased in his/her name and
     qualifying as Individual Retirement Account or Individual Retirement
     Annuities exceed:

     a. $2,000 annually; or

     b. The sum of the maximum annual contribution allowed for the annuitant
        under a Simplified Employee Pension (SEP-IRA) as described in section
        408(j) of the Internal Revenue Code; or

     c. The maximum amount eligible for rollover treatment under sections
        402(c)(4), 403(a)(4), 403(b)(8), or 408(d)(3) of the Internal Revenue
        Code.

By applying for this contract, the Annuitant acknowledges receipt of a
disclosure statement provided by the Company describing this Individual
Retirement Annuity.

  This Endorsement is made a part of the annuity contract to which it is
attached.  Its purpose is to continue to qualify the annuity contract as a Tax-
Sheltered Annuity under Section 403(b) of the Internal Revenue Code ("Code").

  If provisions of this Endorsement conflict with provisions of the annuity
contract, the Endorsement shall control.  The effective date of this Endorsement

  This annuity contract is subject to Section 403(b) of the Code.  Your

          then by the following April 15 we will return to you the amount that
          is over the limit. We must, by law, report this returned amount to the

       2. If you make elective salary deferrals in any tax year to other
          Section 403(b) plans in addition to this annuity contract, then these

          whether your total for the tax year has exceeded the limit under
          Section 402(g).

       3. If your elective salary deferrals to all Section 403(b) plans in any

USAA number ________________________
Social Security number _________________________

        ATTACH THIS FORM AND YOUR CURRENT CONTRACT TO YOUR APPLICATION
                      FOR THE USAA LIFE VARIABLE ANNUITY.

I, _____________________________________, the undersigned, own the following:

 POLICY/CONTRACT     ISSUED BY:        ADDRESS:      INSURED/ANNUITANT'S NAME
     NUMBER:

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

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

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

collectively called "Old Contract(s)" which I hereby agree to exchange pursuant
to Section 1035 of the Internal Revenue Code for a USAA Life Variable Annuity,
called "New Contract," if USAA Life Insurance Company ("USAA Life") approves my
application, dated _____________________ for the New Contract and I accept it.

In consideration of USAA Life's furnishing this form and assisting me with the
exchange of contracts under Section 1035 of the Internal Revenue Code, I hereby
further represent and agree as follows:

At the time of the exchange, is the Old Policy a Modified Endowment Contract
(MEC) under Internal Revenue Code Section 7702A?  [  ] YES   [  ] NO

1. OWNERSHIP OF OLD CONTRACT(S)
   I am the sole owner of the Old Contract(s). No other person (including
   fiduciaries whether or not court-appointed), firm, corporation or
   governmental unit has any legal or equitable claim or interest in or against
   the Old Contract(s), except as follows (describe):

    NOTE:  COLLATERAL ASSIGNEES, IRREVOCABLE BENEFICIARIES, ETC., MUST SIGN ON
                           BACK OF FORM AS INDICATED.
2. ABSOLUTE ASSIGNMENT OF OLD CONTRACT(S)
I hereby assign, irrevocably transfer and deliver the Old Contract(s) described
above to USAA Life Insurance   Company, Federal ID #74-1472662, together with
all right, title and interest therein and thereto.  My copy of this   form is my
receipt for the Old Contract(s).

3. USAA LIFE WILL NOT PAY PREMIUMS ON OLD CONTRACT(S)

  I understand and agree that USAA Life is not obligated to and will not make
any premium payments on the Old   Contract(s).  Therefore, I further agree for
myself, my heirs and assigns that USAA Life is not liable if the Old
Contract(s) lapses for non-payment of premiums.  I understand that if the Old
Contract(s) is reassigned to me under   the terms of Paragraph 5, and it has
lapsed because premiums have not been paid, I can reinstate it only if the terms
of the Old Contract(s) permit it to be reinstated.

4. SURRENDER OF OLD CONTRACT(S)
   I understand and agree that:
   USAA Life will apply for the surrender of the Old Contract(s) for its cash
value.  Upon receipt of the cash proceeds,   USAA Life will issue a New Contract
for delivery to me.  USAA Life will apply the entire cash surrender value or a
portion thereof that it receives from the Old Contract(s) as a non-repeating
premium for the New Contract issued by   USAA Life.

5. REASSIGNMENT OF OLD CONTRACT(S)
   In the event:
     [ ] I refuse to accept the New Contract; or

     [ ] I return the New Contract to USAA Life under the Free Look Provision
         of the New Contract; then this Agreement shall be null and void and
         USAA Life shall reassign the Old Contract(s) to me or my legal
         representative, whereupon USAA Life shall have no further obligation
         with respect to the Old Contract(s).

   I UNDERSTAND THAT AFTER THE SURRENDER DATE, THE OLD CONTRACT(S) CANNOT BE
        RETURNED TO ME AND THAT NO DEATH BENEFIT WILL BE PAID UNDER IT.

                             ORIGINAL INCORPORATION


General remarks and official action taken:

   On this day, came on for consideration by the Commissioner of Insurance,
   the application of Colonel Charles E. Cheever, Colonel Carlton G. Schenken
   and Colonel Amel T. Leonard for approval of the Incorporation of USAA LIFE
   INSURANCE COMPANY, San Antonio, Texas.

   A public hearing on the application was held before the Commissioner of
   Insurance on June 24, 1963, at 10:00 A.M., in the offices of the State Board
   of  Insurance, 1110 San Jacinto, Austin, Texas, at which hearing Colonel
   Charles E. Cheever and Colonel Carlton G. Schenken, incorporators, and
   Joe S. Moore, attorney, appeared and gave evidence and testimony in support
   of the application.

   At such hearing, evidence was presented that all of the incorporators are
   adult residents of the State of Texas; that the proposed location of the
   insurance company will be in San Antonio, Bexar County, Texas; that notice of
   the hearing was published in a newspaper of general circulation in Bexar
   County, Texas, ten (10) days in advance of the hearing; that the company
   proposes to conduct a life, health and accident insurance business; that the
   proposed capital will be TWO MILLION DOLLARS ($2,000,000) divided into Twenty
   Thousand (20,000) shares of stock of the par value of ONE HUNDRED DOLLARS
   ($100) per share, and that the company will be possessed of paid in surplus
   in the amount of ONE MILLION DOLLARS ($1,000,000); that not less than fifty
   percent (50%) of the authorized capital stock has been subscribed in good
   faith and fully paid for; that the capital and surplus is the bona fide
   property of such company, and has been paid into the company; and that SIXTY-
   ONE THOUSAND TWO HUNDRED FIFTY-FIVE DOLLARS AND FIFTY-FOUR CENTS ($61,255.54)
   of such capital and surplus is cash on deposit with the Frost National Bank,
   San Antonio, Texas, and that the remainder of such capital and surplus is in
   the form of securities authorized by Article 3.02 of the Texas Insurance Code
   and is in the hands of the incorporators.



   From the evidence and testimony presented at such hearing, it appears to the
   Commissioner that: (1) the minimum capital and surplus, as required by law,
   is the bona fide property of the company; (2) the proposed officers,
   directors and managing executives have sufficient insurance experience,
   ability and standing to render success of the proposed company probable; and
   (3) the applicants are acting in good faith.

transactions under Contracts or Policies will be effected at the Fund's net
asset value per share as of the close of business on the Business Day the order
is received by the Company or its designee, as agent for the Trust, provided
that such order is received prior to the time the  Fund calculates its net asset
value on that Business Day.  If such order is received after that time, the
order will be effected at the Fund's net asset value as of the close of business
on the next Business Day.  Business Day shall mean any day on which the Trust
calculates the net asset value of its Funds pursuant to rules of the SEC and as
described in the Trust's Prospectus.  Any orders to

                                       3
<PAGE>
 
purchase shares of an available Fund not based on transactions under Contracts
or Policies will be effected at the Fund's net asset value per share next
computed after the order is received by the Trust.

     3.3  The Trust will redeem for cash from the Company those full or
fractional shares of each Fund that the Company requests from time to time.  The
Trust will effect any orders to redeem shares of an available Fund based on
transactions under Contracts or Policies at the Fund's net asset value per share
computed as of the close of business on the Business Day the order is received
by the Company or its designee, as agent for the Trust, provided that such order
is received prior to the time the Fund calculates its net asset value on that
Business Day.  If such order is received after that time, the order will be
effected at the Fund's net asset value as of the close of business on the next
Business Day.  Any orders to redeem shares of an available Fund not based on
transactions under Contracts or Policies will be effected at the Fund's net
asset value per share next computed after the order is received by the Trust.

     3.4  The Trust reserves the right to pay any portion of a redemption in
kind of portfolio securities, if the Trust's board of trustees (the "Board of
Trustees") determines that it would be detrimental to the best interests of the
Shareholders to make a redemption wholly in cash.

     3.5  No orders for the sale, redemption or repurchase of the Trust's shares
(nor payment for shares, in the case of a purchase) shall be transmitted to the
Underwriter.  Sales, redemptions and repurchases shall be effected directly by
the Company or its designee as transfer agent of the Trust.  Payment for shares
shall be transmitted by the Company or its designee directly to the Trust's
custodian.  Redemption and repurchase proceeds shall be allocated by the Company
directly to the Trust's custodian.

     3.6  The Trust shall have the right to suspend redemption of shares of any
Fund pursuant to the conditions set forth in the Prospectus.  The Trust shall

                                       4
<PAGE>
 
suspend redemption of such shares, or at any other time when there shall have
occurred an extraordinary event or circumstance which, in the reasonable
judgment of the Trust, makes it impractical or inadvisable to continue to sell
any such shares.

     3.7  The Trust shall give the Underwriter prompt notice of any such
suspension and shall promptly furnish such other information in connection with
the sale and redemption of Trust shares as the Underwriter reasonably requests.

     3.8  The Board of Trustees may refuse to sell shares of any Fund to the
Company, or suspend or terminate the offering of shares of any Fund, if such
action is required by law or by regulatory authorities having jurisdiction or
is, in the sole discretion of the Trustees, acting in good faith and in light of
their fiduciary duties under Federal and any applicable state laws,  necessary
in the best interests of the Shareholders of the Trust.

     3.9  The Trust agrees that its shares shall be sold only to the Company.
No shares of any Fund may be sold to the general public or to any life insurance
company other than the Company.

     3.10  Issuance and transfer of the Trust's shares shall be by book entry
only.  Stock certificates shall not be issued to the Company.  Shares ordered
from the Trust shall be recorded in an appropriate title for the Company.

     3.11  The Trust shall furnish notice promptly to the Company of any income,
dividends or capital gain distributions payable on the shares of any Fund.  The
Company hereby elects to receive all such income, dividends and capital gain
distributions as are payable on Fund shares in additional shares of that Fund.
The Company reserves the right to revoke this election and to receive all such
income, dividends and capital gain distributions in cash.  The Trust shall
notify the Company of the number of shares so issued as payment of such income,
dividends and distributions.

     3.12  The Trust shall make the net asset value per share for each Fund
available to the Company or its designee each day Monday through Friday, except
days on which the New

                                       5
<PAGE>
 
York Stock Exchange is closed, as soon as reasonably practical after the net
asset value per share is calculated.

     3.13  The Trust may establish additional Funds to provide additional
funding media for the Contracts or Policies, or delete, combine, or modify
existing Funds.  The shares of any additional Fund may be made available to an
Account by the Trust, pursuant to the terms of this Agreement, and any
applicable reference to any Fund, the Trust or its shares herein shall include a
reference to any such additional Fund.

upon having a reasonable basis for believing that a Fund has ceased to so
qualify or that it might not so qualify in the future.

     (b)  The Company represents that it believes, in good faith, that the

the regulations thereunder.  The Company shall make every effort to continue to
meet such definitional requirements, and it shall notify the Trust and the
Underwriter immediately upon having a reasonable basis for believing that such
requirements have ceased to be met or that they might not be met in the future.

agreement with the Underwriter, which also serves as the investment adviser to
the Trust, the Underwriter is and shall be responsible for managing the Trust in

set forth in the Prospectus.  The Trust represents that these objectives,
policies and restrictions do and shall include operating as (i) a RIC in

Code and regulations thereunder.  The Trust has adopted and shall maintain
procedures for ensuring that the Trust is managed in compliance with Subchapter
M and Section 817(h) of the Code and the regulations thereunder.  On request,
the Trust shall also provide the Company with such materials, cooperation and
assistance as may be reasonably necessary for the Company or any person
designated by the Company to review from time to time the procedures and
practices of the Underwriter, or any other provider of services to the Trust for
ensuring that the Trust is managed in compliance with Subchapter M and Section
817(h) of the Code and the regulations thereunder.

     (f)  The Trust shall furnish to the Company on a regular basis reports of
all of the investments of each Fund in a form sufficient to permit the Company
to determine whether each Fund is in compliance with the diversification
requirements of Section 817(h) of the

                                       7
<PAGE>
 
Code and the regulations thereunder and shall take immediate action, on learning
through its own monitoring, or on advice from the Company, that any Fund is not
in compliance with such requirements, to return to compliance with such
requirements.

     (g)  If any Fund is found not to comply with the diversification
requirements at the end of a calendar quarter and the 30-day grace period
allowed under the Code regulations, the Trust shall take all appropriate efforts
immediately to restore any such Fund to compliance and shall fully cooperate
with the Company in any effort to correct such diversification failure under
procedures now or hereafter established by the Internal Revenue Service,
including those set forth in Revenue Procedure 92-25.

     (h)  Any additional income tax that is payable by a Contractowner, with any
applicable interest and penalty thereon, as a result of the failure of any Fund
to comply with either Subchapter M or Section 817(h) of the Code and the
regulations thereunder, shall be borne by the Company.

9. INDEMNIFICATION.
   --------------- 
     9.1  The Underwriter shall indemnify and hold harmless the Trust and the
Company and each of their Trustees, directors and officers (or former Trustees,
directors and officers)

                                       19
<PAGE>
 
and each person, if any, who controls the Trust or the Company within the
meaning of Section 15 of the 1933 Act (collectively, "Indemnitees") against any
loss, liability, claim, damage, or expense (including the reasonable cost of
investigating and defending against the same and any counsel fees reasonably
incurred in connection therewith) incurred by any Indemnitees under the 1933 Act
or under common law or otherwise which arise out of or are based upon (1) any
untrue or alleged untrue statement of a material fact contained in information
furnished to the Trust by the Underwriter for use in the Trust's registration
statement, Prospectus, or annual or interim reports to Shareholders, (2) any
omission or alleged omission to state a material fact in connection with such
information furnished by the Underwriter to the Trust which is required to be
stated in any of such documents or necessary to make such information not
misleading, (3) any misrepresentation or omission or alleged misrepresentation
or omission to state a material fact on the part of the Underwriter or any agent
or employee of the Underwriter or any other person for whose acts the
Underwriter is responsible, unless such misrepresentation or omission or alleged
misrepresentation or omission was made in reliance on information furnished by
the Trust, or (4) the willful misconduct or failure to exercise reasonable care
and diligence on the part of the Underwriter or any agent or employee of the
Underwriter or any other person for whose acts the Underwriter is responsible
with respect to services rendered under this Agreement.  This indemnity
provision, however, shall not operate to protect any officer or Trustee of the
Trust from any liability to the Trust or any shareholder by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of his or her
duties.

     In case any action shall be brought against any Indemnitee, the Underwriter
shall not be liable under its indemnity agreement contained in this paragraph
with respect to any claim made against any Indemnitee, unless the Indemnitee
shall have notified the Underwriter in writing within a reasonable time after
the summons or other first legal process giving information of the nature of the
claim shall have been served upon the Indemnitee (or after

                                       20
<PAGE>
 
the Indemnitee shall have received notice of such service on any designated
agent), but failure to notify the Underwriter of any such claim shall not
relieve it from liability to the Indemnitees against whom such action is brought
otherwise than on account of this Section 9.1.  The Underwriter will be entitled
to participate at its own expense in the defense, or, if it so elects, to assume
the defense of any suit brought to enforce any such liability, but if the
Underwriter elects to assume the defense, such defense shall be conducted by
counsel chosen by it and satisfactory to the Indemnitees which are defendants in
the suit. In the event the Underwriter elects to assume the defense of any such
suit and retain such counsel, the Indemnitees which are defendants in the suit
shall bear the fees and expenses of any additional counsel retained by them,
but, in case the Underwriter does not elect to assume the defense of any such
suit, the Underwriter will reimburse the Indemnitees which are defendants in the
suit for the reasonable fees and expenses of any counsel retained by them.  The
Underwriter shall promptly notify the Trust and the Company of the commencement
of any litigation or proceedings in connection with the issuance or sales of the
shares.

     9.2  The Company shall indemnify and hold harmless the Trust and the
Underwriter and each of their Trustees, directors and officers (or former
Trustees, directors and officers) and each person, if any, who controls the
Trust or the Underwriter within the meaning of Section 15 of the 1933 Act
(collectively, "Indemnitees") against any loss, liability, claim, damage, or
expense (including the reasonable cost of investigating and defending against
the same and any counsel fees reasonably incurred in connection therewith)
incurred by any Indemnitees under the 1933 Act or under common law or otherwise
which arise out of or are based upon (1) any untrue or alleged untrue statement
of a material fact contained in information furnished to the Trust for use in
the Trust's registration statement, Prospectus, or annual or interim reports to
Shareholders, (2) any omission or alleged omission to state a material fact in
connection with such information furnished by the Company to the Trust or the
Underwriter, which is required to be stated in any of such documents or
necessary to

                                       21
<PAGE>
 
make such information not misleading, (3) any misrepresentation or omission or
alleged misrepresentation or omission to state a material fact on the part of
the Company or any agent or employee of the Company or any other person for
whose acts the Company is responsible, unless such misrepresentation or omission
or alleged misrepresentation or omission was made in reliance on information
furnished by the Trust or the Underwriter, or (4) the willful misconduct or
failure to exercise reasonable care and diligence on the part of the Company or
any agent or employee of the Company or any other person for whose acts the
Company is responsible with respect to services rendered under this Agreement.
This indemnity provision, however, shall not operate to protect the Underwriter
or any officer or Trustee of the Trust from any liability to the Trust or any
shareholder by reason of willful misfeasance, bad faith, gross negligence or
reckless disregard of their duties.

     Notwithstanding Section 9.1, the Company shall indemnify and hold the Trust
and the Underwriter and each of its Trustees, directors and officers, (or former
Trustees, directors and officers) and each person, if any, who controls the
Trust within the meaning of Section 15 of the 1933 Act, harmless from all loss,
cost, damage, and expense, including reasonable attorneys' fees, incurred by the
Trust as a result of the failure at any time of any Fund of the Trust (i) to
operate as a regulated investment company in compliance with Subchapter M of the
Code and the regulations thereunder or (ii) to comply with the investment
diversification rules of Section 817(h) of the Code and the regulations
thereunder; or (iii) any error or omission in any accounting data or calculation
the collection and maintenance of which data or the production of which
calculation is made the responsibility of the Company under this Agreement.

     In case any action shall be brought against any Indemnitee, the Company
shall not be liable under its indemnity agreement contained in this paragraph
with respect to any claim made against any Indemnitee, unless the Indemnitee
shall have notified the Company in writing within a reasonable time after the
summons or other first legal process giving

                                       22
<PAGE>
 
information of the nature of the claim shall have been served upon the
Indemnitee (or after the Indemnitee shall have received notice of such service
on any designated agent), but failure to notify the Company of any such claim
shall not relieve it from liability to the Indemnitees against whom such action
is brought otherwise than on account of this Section 9.2.  The Company will be
entitled to participate at its own expense in the defense, or, if it so elects,
to assume the defense of any suit brought to enforce any such liability, but if
the Company elects to assume the defense, such defense shall be conducted by
counsel chosen by it and satisfactory to the Indemnitees which are defendants in
the suit. In the event the Underwriter elects to assume the defense of any such
suit and retain such counsel, the Indemnitees which are defendants in the suit
shall bear the fees and expenses of any additional counsel retained by them,
but, in case the Company does not elect to assume the defense of any such suit,
the Company will reimburse the Indemnitees that are defendants in the suit for
the reasonable fees and expenses of any counsel retained by them.  The Company
shall promptly notify the Trust and the Underwriter of the commencement of any
litigation or proceedings in connection with the issuance or sales of the
shares.

10.  REGULATORY REPORTS.

     The Underwriter, the Company and the Trust agree to furnish to each other,
as appropriate, necessary cooperation, assistance and information in the
following matters (which shall nevertheless be primarily the responsibility of
the Company hereunder) :

     10.1  The preparation of all reports as required by Federal or state law or
regulations;

     10.2  The furnishing of any information or reports in connection with the
services provided hereunder as may be requested by any state insurance
commissioner, which request is made to ascertain whether the operations of any
of the parties are being conducted in a manner consistent with applicable state
insurance laws or regulations.

                                       23

     10.3  The preparation of prospectuses, statements of additional
information, registration statements, and amendments thereto that may be
required by Federal or other laws or by the rules or regulations of any duly
authorized commission or administrative body.

11.  DURATION AND TERMINATION OF AGREEMENT.

     11.1  This Agreement shall become effective as of February 18, 1998, except
for the deletion of former Section 8.5 above which shall be deemed to have
become effective on January 1, 1998, and shall remain in force until January 1,
2000 and thereafter, but only so long as such continuance is specifically
approved at least annually by (i) the Board of Trustees, or by the vote of a
majority of the outstanding voting securities of the Trust, cast in person or by
proxy, and (ii) a majority of those Trustees who are not parties to this
Agreement or interested persons of any such party cast in person at a meeting
called for the purpose of voting on such approval.  Notwithstanding the
foregoing, the Board of Trustees may, from time to time, establish a new
effective date for the continuance of this Agreement with respect to any initial
Fund and/or additional Fund; provided, that such new effective date precedes the
then current termination date of the Agreement.

     11.2  This Agreement may be terminated at any time without the payment of
any penalty, by the Board of Trustees, by vote of a majority of the outstanding
voting securities of the Trust, or by the Underwriter or the Company on 120 days
written notice to the other party. This Agreement shall automatically terminate
in the event of its assignment or in the event of termination of the Advisory
Agreement between the Underwriter and any Fund of the Trust.

     11.3  The terms "assignment," "vote of a majority of the outstanding voting
securities" and "interested person," when used in this Agreement, shall have the
respective meanings specified in the 1940 Act.

12.  GOVERNING LAW.

of Texas and the applicable provisions of the 1940 Act. To the extent the
applicable law of the State of Texas, or any of the provisions herein, conflict
with the applicable provisions of the 1940 Act, the latter shall control.

13.  CONFIDENTIALITY.

     Neither the Company nor the Underwriter shall disclose or use any records
or information obtained hereunder in any manner whatsoever except as expressly
authorized hereunder and, further, they shall keep confidential any information
obtained pursuant to their relationship with the Trust set forth herein, and
disclose such information only if the Trust has authorized such disclosure, or
if such disclosure is expressly required by applicable Federal or state
regulatory authorities.

                        FORM OF PARTICIPATION AGREEMENT

     PARTICIPATION AGREEMENT (the "Agreement") made by and between SCUDDER
VARIABLE LIFE INVESTMENT FUND (the "Fund"), a Massachusetts business trust
created under a Declaration of Trust dated March 15, 1985, as amended, with a
principal place of business in Boston, Massachusetts and USAA LIFE INSURANCE
COMPANY, a Texas corporation (the "Company"), with a principal place of business
in San Antonio, Texas on behalf of the Separate Account of USAA Life Insurance
Company, a separate account of the Company, and any other separate account of
the Company as designated by the Company from time to time, upon written notice
to the Fund in accordance with Section 10 herein (each, an "Account").

     WHEREAS, the Fund acts as the investment vehicle for the separate accounts
established for variable life insurance policies and variable annuity contracts
(collectively referred to herein as "Variable Insurance Products") to be offered
by insurance companies which have entered into participation agreements
substantially identical to this Agreement ("Participating Insurance Companies")
and their affiliated insurance companies; and

     WHEREAS, the beneficial interest in the Fund is divided into several series
of shares of beneficial interest ("Shares"), and additional series of Shares may
be established, each designated a "Portfolio" and representing the interest in a
particular managed portfolio of securities; and

     WHEREAS, it is in the best interest of Participating Insurance Companies to
make capital contributions if required so that the annual expenses of each
Portfolio of the Fund in which a
<PAGE>
 
Participating Insurance Company is a shareholder will not exceed a fixed
percentage of the Portfolio's average annual net assets; and

     WHEREAS, the Parties desire to evidence their agreement as to certain other
matters,

     NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements hereinafter contained, the parties hereto agree as follows:

     1.   Additional Definitions.
          ---------------------- 
     For the purposes of this Agreement, the following definitions shall apply:

          (a) The "expenses of a Portfolio" for any fiscal year shall mean the
expenses for such fiscal year as shown in the Statement of Operations (or
similar report) certified by the Fund's independent public accountants;

          (b) A "Portfolio's average daily net assets" for each fiscal year
shall mean the sum of the net asset values determined throughout the year for
the purpose of determining net asset value per Share, divided by the number of
such determinations during such year;

          (c) The Company's "Required Contribution" on behalf of each Account in
respect of a Portfolio for any fiscal year shall mean an amount equal to the
expenses of that Portfolio for such year minus the below-indicated percentage of
that Portfolio's average daily net assets for the year:

          International Portfolio. . . . . . . . . .  1.50%
          Each other Portfolio. . . . . . . . . . . . 0.75%

multiplied by a fraction the denominator of which is the average daily net
assets of that Portfolio and the numerator of which is

                                       2
<PAGE>
 
the average daily net asset value of the Shares of that Portfolio owned by each
Account (referred to herein as a "Participating Shareholder").  The Company's
Required Contribution in respect of a Portfolio shall be pro-rated based on the
number of business days on which this Agreement is in effect for periods of less
than a fiscal year.

          (d) The "average daily net asset value of the Shares of the Portfolio"
owned by the Account for any fiscal year of the Fund shall mean the greater of
(i) $500,000 or (ii) the sum of the aggregate net asset values of the Shares so
owned determined during the fiscal year, as of each determination of the net
asset value per Share, divided by the total number of determinations of net
asset value during such year.

          (e) "Shares" means shares of beneficial interest, without par value,
of any Portfolio, now or hereafter created, of the Fund.

     2.   Capital Contribution.
          -------------------- 

     The Company on behalf of each Account shall, within sixty days after the
end of each fiscal year of the Fund, make a capital contribution to the Fund in
respect of each Portfolio equal to the Required Contribution for that Portfolio
for such year; provided, however, that in the event that both clauses (i) and
(ii) of paragraph (d) of Section 1 of this Agreement or similar agreements are
applicable to different Participating Insurance Companies during the same fiscal
year, there shall be a proportionate reduction of the Required Contribution of
each Participating Insurance Company to which said clause (ii) is applicable so
that the total of all required capital contributions to the Fund on

                                       3
<PAGE>
 
behalf of any Portfolio is not greater than the excess of the expenses of that
Portfolio for that fiscal year less the percentage of that Portfolio's total
expenses set forth in paragraph (c) of Section 1 of this Agreement for such
fiscal year.

     3.   Duty of Fund to Sell.
          -------------------- 

     The Fund shall make its Shares available for purchase at the applicable net
asset value per Share by Participating Insurance Companies and their affiliates
and separate accounts on those days on which the Fund calculates its net asset
value pursuant to rules of the Securities and Exchange Commission; provided,
however, that the Trustees of the Fund may refuse to sell Shares of any
Portfolio to any person, or suspend or terminate the offering of Shares of any
Portfolio, if such action is required by law or by regulatory authorities having
jurisdiction or is, in the sole discretion of the Trustees, necessary in the
best interest of the shareholders of any Portfolio.


     4.   Requirement to Execute Participation Agreement; Requests.
          -------------------------------------------------------- 

     Each Participating Insurance Company shall, prior to purchasing Shares in
the Fund, execute and deliver a participation agreement in a form substantially
identical to this Agreement.

     The Fund shall make available, upon written request from the Participating
Insurance Company given in accordance with Paragraph 10, to each Participating
Insurance Company which has executed an Agreement and which Agreement has not
been terminated pursuant to Paragraph 8 (i) a list of all other Participating
Insurance Companies, and (ii) a copy of the Agreement as executed by any other
Participating Insurance Company.

                                       4
<PAGE>
 
     The Fund shall also make available upon request to each Participating
Insurance Company which has executed an Agreement and which Agreement has not
been terminated pursuant to Paragraph 8, the net asset value of any Portfolio of
the Fund as of any date upon which the Fund calculates the net asset value of
its Portfolios for the purpose of purchase and redemption of Shares.

     5.   Indemnification.
          --------------- 

     (a)  The Company agrees to indemnify and hold harmless the Fund and each of
its Trustees and officers and each person, if any, who controls the Fund within
the meaning of Section 15 of the Securities Act of 1933 (the "Act") against any
and all losses, claims, damages, liabilities or litigation (including legal and
other expenses), arising out of the acquisition of any Shares by any person, to
which the Fund or such Trustees, officers or controlling person may become
subject under the Act, under any other statute, at common law or otherwise,
which (i) may be based upon any wrongful act by the Company, any of its
employees or representatives, any affiliate of or any person acting on behalf of
the Company or a principal underwriter of its insurance products, or (ii) may be
based upon any untrue statement or alleged untrue statement of a material fact
contained in a registration statement or prospectus covering Shares or any
amendment thereof or supplement thereto or the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading if such a statement or omission was made
in reliance upon information furnished to the Fund by the Company, or (iii) may
be based on any untrue statement or alleged untrue statement of a material fact
contained in a

                                       5
<PAGE>
 
registration statement or prospectus covering insurance products
sold by the Company or any insurance company which is an affiliate thereof, or
any amendments or supplement thereto, or the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statement or statements therein not misleading, unless such statement or
omission was made in reliance upon information furnished to the Company or such
affiliate by or on behalf of the Fund; provided, however, that in no case (i) is
the Company's indemnity in favor of a Trustee or officer or any other person
deemed to protect such Trustee or officer or other person against any liability
to which any such person would otherwise be subject by reason of willful
misfeasance, bad faith, or gross negligence in the performance of his duties or
by reason of his reckless disregard of obligations and duties under this
Agreement or (ii) is the Company to be liable under its indemnity agreement
contained in this Paragraph 5 with respect to any claim made against the Fund or
any person indemnified unless the Fund or such person, as the case may be, shall
have notified the Company in writing pursuant to Paragraph 10 within a
reasonable time after the summons or other first legal process giving
information of the nature of the claims shall have been served upon the Fund or
upon such person (or after the Fund or such person shall have received notice of
such service on any designated agent), but failure to notify the Company of any
such claim shall not relieve the Company from any liability which it has to the
Fund or any person against whom such action is brought otherwise than on account
of its indemnity agreement contained in this Paragraph 5. The Company shall be
entitled to participate, at its own expense,

                                       6
<PAGE>
 
in the defense, or, if it so elects, to assume the defense of any suit brought
to enforce any such liability, but, if it elects to assume the defense, such
defense shall be conducted by counsel chosen by it and satisfactory to the Fund,
to its officers and Trustees, or to any controlling person or persons, defendant
or defendants in the suit. In the event that the Company elects to assume the
defense of any such suit and retain such counsel, the Fund, its officers and
Trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them,
but, in case the Company does not elect to assume the defense of any such suit,
the Company will reimburse the Fund, or such officers and Trustees or
controlling person or persons, defendant or defendants in such suit, for the
reasonable fees and expenses of any counsel retained by them. The Company agrees
promptly to notify the Fund pursuant to Paragraph 10 of the commencement of any
litigation or proceedings against it in connection with the issue and sale of
any Shares.

     (b)  The Fund agrees to indemnify and hold harmless the Company and each of
its directors and officers and each person, if any, who controls the Company
within the meaning of Section 15 of the Act against any and all losses, claims,
damages, liabilities or litigation (including legal and other expenses) to which
it or such directors, officers or controlling person may become subject under
the Act, under any other statute, at common law or otherwise, arising out of the
acquisition of any Shares by any person which (i) may be based upon any wrongful
act by the Fund, any of its employees or representatives or a principal
underwriter of the

                                       7
<PAGE>
 
Fund, or (ii) may be based upon any untrue statement or alleged untrue statement
of a material fact contained in a registration statement or prospectus covering
Shares or any amendment thereof or supplement thereto or the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading unless such statement or
omission was made in reliance upon information furnished to the Fund by the
Company or (iii) may be based on any untrue statement or alleged untrue
statement of a material fact contained in a registration statement or prospectus
covering insurance products sold by the Company, or any amendment or supplement
thereto, or the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statement or statements
therein not misleading, if such statement or omission was made in reliance upon
information furnished to the Company by or on behalf of the Fund; provided,
however, that in no case (i) is the Fund's indemnity in favor of a director or
officer or any other person deemed to protect such director or officer or other
person against any liability to which any such person would otherwise be subject
by reason of willful misfeasance, bad faith, or gross negligence in the
performance of his duties or by reason of his reckless disregard of obligations
and duties under this Agreement or (ii) is the Fund to be liable under its
indemnity agreement contained in this Paragraph 5 with respect to any claims
made against the Company or any such director, officer or controlling person
unless it or such director, officer or controlling person, as the case may be,
shall have notified the Fund in writing pursuant to Paragraph 10 within a
reasonable time after the summons

                                       8
<PAGE>
 
or other first legal process giving information of the nature of the claim shall
have been served upon it or upon such director, officer or controlling person
(or after the Company or such director, officer or controlling person shall have
received notice of such service on any designated agent), but failure to notify
the Fund of any claim shall not relieve it from any liability which it may have
to the person against whom such action is brought otherwise than on account of
its indemnity agreement contained in this Paragraph. The Fund will be entitled
to participate at its own expense in the defense, or, if it so elects, to assume
the defense of any suit brought to enforce any such liability, but if the Fund
elects to assume the defense, such defense shall be conducted by counsel chosen
by it and satisfactory to the Company, its directors, officers or controlling
person or persons, defendant or defendants, in the suit. In the event the Fund
elects to assume the defense of any such suit and retain such counsel, the
Company, its directors, officers or controlling person or persons, defendant or
defendants in the suit, shall bear the fees and expenses of any additional
counsel retained by them, but, in case the Fund does not elect to assume the
defense of any such suit, it will reimburse the Company or such directors,
officers or controlling person or persons, defendant or defendants in the suit,
for the reasonable fees and expenses of any counsel retained by them. The Fund
agrees promptly to notify the Company pursuant to Paragraph 10 of the
commencement of any litigation or proceedings against it or any of its officers
or Trustees in connection with the issuance or sale of any Shares.

     6.   Procedure for Resolving Irreconcilable Conflicts.
          ------------------------------------------------ 

     (a) The Trustees of the Fund will monitor the operations of the Fund for
the existence of any material irreconcilable conflict among the interests of all
the contract holders and policy owners of Variable Insurance Products (the
"Participants") of all separate accounts investing in the Fund.  An
irreconcilable material conflict may arise, among other things, from:  (a) an
action by any state insurance regulatory authority; (b) a change in applicable
insurance laws or regulations; (c) a tax ruling or provision of the Internal
Revenue Code or the regulations thereunder; (d) any other development relating
to the tax treatment of insurers, contract holders or policy owners or
beneficiaries of Variable Insurance Products; (e) the manner in which the
investments of any Portfolio are being managed; (f) a difference in voting
instructions given by variable annuity contract holders, on the one hand, and
variable life insurance policy owners, on the other hand, or by the contract
holders or policy owners of different participating insurance companies; or (g)
a decision by an insurer to override the voting instructions of Participants.

     (b) The Company will be responsible for reporting any potential or existing
conflicts to the Trustees of the Fund.  The Company will be responsible for
assisting the Trustees in carrying out their responsibilities under this
Paragraph 6(b) and Paragraph 6(a), by providing the Trustees with all
information reasonably necessary for the Trustees to consider the issues raised.
The Fund will also request its investment adviser to report to the Trustees any
such conflict which comes to the attention of the adviser.

                                       10
<PAGE>
 
     (c) If it is determined by a majority of the Trustees of the Fund, or a
majority of its disinterested Trustees, that a material irreconcilable conflict
exists involving the Company, the Company shall, at its expense, and to the
extent reasonably practicable (as determined by a majority of the disinterested
Trustees), take whatever steps are necessary to eliminate the irreconcilable
material conflict, including withdrawing the assets allocable to some or all of
the separate accounts from the Fund or any Portfolio and reinvesting such assets
in a different investment medium, including another Portfolio of the Fund,
offering to the affected Participants the option of making such a change or
establishing a new funding medium including a registered investment company.

     For purposes of this Paragraph 6(c), the Trustees, or the disinterested
Trustees, shall determine whether or not any proposed action adequately remedies
any irreconcilable material conflict. In the event of a determination of the
existence of an irreconcilable material conflict, the Trustees shall cause the
Fund to take such action, such as the establishment of one or more additional
Portfolios, as they in their sole discretion determine to be in the interest of
all shareholders and Participants in view of all applicable factors, such as
cost, feasibility, tax, regulatory and other considerations.  In no event will
the Fund be required by this Paragraph 6(c) to establish a new funding medium
for any variable contract or policy.

     The Company shall not be required by this Paragraph 6(c) to establish a new
funding medium for any variable contract or policy if an offer to do so has been
declined by a vote of a majority of the Participants materially adversely
affected by the material

                                       11
<PAGE>
 
irreconcilable conflict. The Company will recommend to its Participants that
they decline an offer to establish a new funding medium only if the Company
believes it is in the best interest of the Participants.

     (d) The Trustees' determination of the existence of an irreconcilable
material conflict and its implications promptly shall be communicated to all
Participating Insurance Companies by written notice thereof delivered or mailed,
first class postage prepaid.

     7.   Voting Privileges.
          ----------------- 

     The Company shall be responsible for assuring that its separate account or
accounts participating in the Fund shall use a calculation method of voting
procedures substantially the same as the following:  those Participants
permitted to give instructions and the number of Shares for which instructions
may be given will be determined as of the record date for the Fund shareholders'
meeting, which shall not be more than 60 days before the date of the meeting.
Whether or not voting instructions are actually given by a particular
Participant, all Fund shares held in any separate account or sub-account thereof
and attributable to policies will be voted for, against, or withheld from voting
on any proposition in the same proportion as (i) the aggregate record date cash
value held in such sub-account for policies giving instructions, respectively,
to vote for, against, or withhold votes on such proposition, bears to (ii) the
aggregate record date cash value held in the sub-account for all policies for
which voting instructions are received.  Participants continued in effect under
lapse options will not be permitted to give voting instructions.

                                       12
<PAGE>
 
Shares held in any other insurance company general or separate account or sub-
account thereof will be voted in the proportion specified in the second
preceding sentence for shares attributable to policies.

     8.   Duration and Termination.
          ------------------------ 

     This Agreement shall remain in force for the period ending five years from
the date of its execution (such date and any anniversary of such date being
hereinafter called a "Renegotiation Date"), and from year to year thereafter
provided that neither the Company nor the Fund shall have given written notice
to the other within thirty (30) days prior to a Renegotiation Date that it
desires to renegotiate the amount of contribution to capital due hereunder
("Renegotiation Notice").  If a Renegotiation Notice is properly given as
aforesaid and the Fund and the Company shall fail, within sixty (60) days after
the Renegotiation Date, either to enter into an amendment to this Agreement or a
written acknowledgment that the Agreement shall continue in effect, this
Agreement shall terminate as of the one hundred twentieth day after such
Renegotiation Date.  If this Agreement is so terminated, the Fund may, at any
time thereafter, automatically redeem the Shares of any Portfolio held by a
Participating Shareholder.  This Agreement may be terminated at any time, at the
option of either of the Company or the Fund, when neither the Company, any
insurance company nor the separate account or accounts of such insurance company
which is an affiliate thereof which is not a Participating Insurance Company own
any Shares of the Fund or may be terminated by either party to the Agreement
upon a determination by a majority of the Trustees of the Fund, or a majority of
its disinterested

                                       13
<PAGE>
 
Trustees, following certification thereof by a Participating Insurance Company
given in accordance with Paragraph 10 that an irreconcilable conflict exists
among the interests of (i) all contract holders and policy holders of Variable
Insurance Products of all separate accounts or (ii) the interests of the
Participating Insurance Companies investing in the Fund. Notwithstanding
anything to the contrary in this Agreement or its termination as provided
herein, the Company's obligation to make a capital contribution to the Fund in
accordance with this Agreement at the time in effect shall continue (i)
following a properly given Renegotiation Notice, in the absence of agreement
otherwise, until termination of this Agreement, and (ii) (except termination due
to the existence of an irreconcilable conflict), following termination of this
Agreement, until the later of the fifth anniversary of the date of this
Agreement or the date on which the Company, its separate account(s) or the
separate account(s) of any affiliated insurance company owns no Shares.

     9.   Compliance.

     The Fund will comply with the provisions of Section 4240(a) of the New York

diversification requirement of Section 817(h)(1) of the Code by having all or

              FORM OF PARTICIPATING CONTRACT AND POLICY AGREEMENT
              ---------------------------------------------------

Ladies and Gentlemen:

     We (sometimes hereinafter referred to as "Investor Services") are the
Principal Underwriter of shares of Scudder Variable Life Investment Fund (the
"Fund"), a no-load, open-end, diversified registered management investment
company established in 1985 as a Massachusetts business trust.  The Fund is a
series fund consisting of the Balanced Portfolio, Bond Portfolio, Capital Growth
Portfolio, International Portfolio, Money Market Portfolio and Growth and Income
Portfolio (individually or collectively hereinafter referred to as the
"Portfolio" or the "Portfolios").  Additional Portfolios may be created from
time to time.  The Fund is the funding vehicle for variable annuity contracts
and variable life insurance policies ("Participating Contracts and Policies") to
be offered to the separate accounts or sub-accounts (the "Accounts") of certain
life insurance companies ("Participating Insurance Companies").  Owners of
Participating Contracts and Policies will designate a portion of their premium
to be invested in Accounts which invest in, or represent an investment in,
directly or indirectly, shares of beneficial interest ("Shares") of the
Portfolios of the Fund.  You are a registered broker-dealer which intends to
offer and sell Participating Contracts and Policies.  In connection with such
offer and sale you will be obligated to deliver the prospectuses of such
Participating Contracts and Policies and, contemporaneously therewith, the
<PAGE>
 
prospectus of the Fund.  Sales of Shares to Participating Insurance Companies or
their affiliates or the separate accounts of either shall be effected solely by
us as principal underwriter of the Fund, and not by you; provided, however, that
you shall be our agent in connection with the receipt of purchase orders for
Fund Shares and not in connection with their offer and sale.  The relationship
between us shall be further governed by the following terms and conditions:

     1.   To the extent, if any, that your activities or the activities of the
          Participating Insurance Companies in connection with the sale of
          Participating Contracts and Policies may constitute the sale of
          Shares, you and we agree that (i) we are the sole "principal
          underwriter" of the Fund and the sole "underwriter" of the Shares as
          those terms are defined in the Investment Company Act of 1940 (the
          "1940 Act") and the Securities Act of 1933 (the "1933 Act"),
          respectively, and (ii) neither you nor the Participating Insurance
          Companies or the Accounts shall be deemed to be "principal
          underwriters" of the Fund or "underwriters" of the Fund within the
          meaning of the 1940 Act and the 1933 Act, respectively.

     2.   You hereby represent and warrant to us as follows:

          (a)  You are a corporation duly organized and validly existing in good
               standing under the laws of the State of Texas and have full power
               and authority to enter into this Agreement.

          (b)  This Agreement has been duly authorized, executed and delivered
               by you and is a valid and binding obligation enforceable against
               you in accordance with its terms.

          (c)  Your compliance with the provisions of this Agreement will not
               conflict with or result in a violation of the provisions of your
               charter or by-laws, or any statute or any judgment, decree,
               order, rule or regulation of any court or governmental agency or
               body having jurisdiction.

     3.   We hereby represent and warrant to you as follows:

          (a)  A registration statement (File No. 2-96461) on Form N-1A with
               respect to the Shares (x) has been prepared by the Fund in
               conformity with the requirements of the 1940 Act and the 1933 Act
               and

               all applicable published instructions, rules and regulations
               (the "Rules and Regulations") of the Securities and Exchange
               Commission (the "Commission"), (y) has been filed with the
               Commission, and (z) is currently effective.  The registration
               statement, including financial statements and exhibits, and the
               final prospectus, including the statement of additional
               information, as subsequently amended and supplemented, are herein
               respectively referred to as the "Registration Statement" and the
               "Prospectus".

          (b)  The Registration Statement and the Prospectus and any amendment
               or supplement thereto will contain all statements required to be
               stated therein and will comply in all material respects with the
               requirements of the 1940 Act, the 1933 Act and the Rules and
               Regulations, and the Registration Statement and any post-
               effective amendment thereto will not contain or incorporate by
               reference any untrue statement of a material fact or omit to
               state any material fact required to be stated therein or
               necessary to make the statements therein, in light of the
               circumstances under which they were made, not misleading, and the
               Prospectus and any amendment or supplement thereto will not
               contain or incorporate by reference any untrue statement of a
               material fact or omit to state a material fact required to be
               stated therein or necessary in order to make the statements
               therein, in light of the circumstances under which they were
               made, not misleading.

          (c)  We are a corporation duly organized and validly existing in good
               standing under the laws of The Commonwealth of Massachusetts and
               have full power and authority to enter into this Agreement.

          (d)  This Agreement has been duly authorized, executed and delivered
               by us and is a valid and binding obligation enforceable against
               us in accordance with its terms.

          (e)  Our compliance with all of the provisions of this Agreement will
               not conflict with or result in a violation of the provisions of
               our charter or by-laws, or any statute or any judgment, decree,
               order, rule or regulation of any court or governmental agency or
               body having jurisdiction over us.

     4.   You hereby covenant and agree with us as follows:

          (a)  You shall be an independent contractor and neither you nor any of
               your directors, officers or employees as such, is or shall be an
               employee of us or of the Fund.  You are responsible for your own
               conduct and

                                       3
<PAGE>
 
               the employment, control and conduct of your agents and employees
               and for injury to such agents or employees or to others through
               your agents or employees.

          (b)  You or one or more Participating Insurance Companies will be
               responsible for insuring compliance with all applicable laws and
               regulations of any regulatory body having jurisdiction over you
               or Participating Contracts and Policies.

          (c)  No person is authorized to make any representations concerning
               Shares except those contained in the Prospectus relating thereto
               and in such printed information as issued by us for use as
               information supplemental to the prospectus.  In offering
               Participating Contracts and Policies you shall, with respect to
               the Fund and the Shares, rely solely on the representations
               contained in the Prospectus and in the above-mentioned
               supplemental information.

          (d)  You are not entitled to any compensation whatsoever from us or
               the Fund with respect to offers of Participating Contracts and
               Policies.

     5.   We hereby covenant and agree with you as follows:

          (a)  If, at any time when a Prospectus relating to the Shares is
               required to be delivered under the 1940 Act, the 1933 Act or the
               Rules and Regulations, we become aware of the occurrence of any
               event as a result of which the Prospectus as then amended or
               supplemented would include any untrue statement of a material
               fact, or omit to state a material fact necessary to make the
               statements therein, in light of the circumstances under which
               made, not misleading, or if we become aware that it has become
               necessary at any time to amend or supplement the Prospectus to
               comply with the 1940 Act, the 1933 Act or the Rules and
               Regulations, we will promptly notify you and promptly request the
               Fund to prepare and to file with the Commission an amendment to
               the Registration Statement or supplement to the Prospectus which
               will correct such statement or omission or an amendment or
               supplement which will effect such compliance, and deliver to you
               copies of any such amendment or supplement.

          (b)  We will cooperate with you by taking such action as may be
               necessary for the Fund to qualify the Shares for offer and sale
               under the securities or Blue Sky laws of any state or
               jurisdiction as you may request and as may be required by
               applicable law, and will continue such qualification in effect so
               long as is required by applicable law in connection with the
               distribution of Shares.

                                       4
<PAGE>
 
     6.   We reserve the right in our discretion, without notice, to suspend
          sales or withdraw the offering of Shares entirely, as to any person or
          generally.  We reserve the right to amend this Agreement at any time
          and you agree that the sale of Participating Contracts and Policies,
          after notice of any such amendment has been sent to you, shall
          constitute your agreement to any such amendment.

     7.   If we elect to provide to you for the purpose of your offering
          Participating Contracts and Policies copies of any Prospectus relating
          to the Shares and printed information supplemental thereto, we shall
          furnish you with such copies as you reasonably request upon the
          payment of reasonable charges therefor by you or one or more
          Participating Insurance Companies.  If we elect not to provide such
          copies of such documents, you or one or more Participating Insurance
          Companies shall bear the entire cost of printing copies for your use.
          You shall not use such copies of such documents printed by you or one

               controls Investor Services within the meaning of Section 15 of
               the 1933 Act, against any loss, liability, damages, claim or
               expense (including the reasonable cost of investigating or
               defending any alleged loss, liability, damages, claim or expense
               and reasonable counsel fees incurred in connection therewith),
               arising by reason of any person's acquiring any Shares, which may
               be based upon the 1933 Act or any other statute or common law,
               and which (i) may be based upon any wrongful act by you, any of
               your employees or representatives, or (ii) may be based upon any
               untrue statement or alleged untrue statement of a material fact
               contained in a registration statement or prospectus covering
               Shares or any amendment thereof or supplement thereto or the
               omission or alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading if such a statement or omission was made
               in reliance upon information furnished to us or the Fund by you,
               or (iii) may be based on any untrue statement or alleged untrue
               statement of a material fact contained in a registration
               statement or prospectus covering insurance products sold by you,
               or any amendments or supplement thereto, or the omission or
               alleged omission to state therein a material fact required to be
               stated therein or

                                       5
<PAGE>
 
               necessary to make the statement or statements therein not
               misleading, unless such statement or omission was made in
               reliance upon information furnished to you or a Participating
               Insurance Company by or on behalf of Investor Services or the
               Fund; provided, however, that in no case (i) is the indemnity by
               you in favor of any person indemnified to be deemed to protect
               Investor Services or any such person against any liability to
               which Investor Services or any such person would otherwise be
               subject by reason of willful misfeasance, bad faith or gross
               negligence in the performance of its or his duties or by reason
               of its or his reckless disregard of its obligations and duties
               under this Agreement, or (ii) are you to be liable under your
               indemnity agreement contained in this paragraph with respect to
               any claim made against Investor Services or any person
               indemnified unless Investor Services or such person, as the case
               may be, shall have notified you in writing within a reasonable
               time after the summons or other first legal process giving
               information of the nature of the claim shall have been served
               upon Investor Services or upon such person (or after Investor
               Services or such person shall have received notice of such
               service on any designated agent), but failure to notify you of
               any such claim shall not relieve you from any liability which you
               may have to Investor Services or any person against whom such
               action is brought otherwise than on account of your indemnity
               agreement contained in this paragraph. You shall be entitled to
               participate, at your own expense, in the defense, or, if you so
               elect, to assume the defense of any suit brought to enforce any
               such liability, but, if you elect to assume the defense, such
               defense shall be conducted by counsel chosen by you and
               satisfactory to Investor Services, or to its officers or
               directors, or to any controlling person or persons, defendant or
               defendants in the suit. In the event that you assume the defense
               of any such suit and retain such counsel, Investor Services or
               such officers or directors or controlling person or persons,
               defendant or defendants in the suit, shall bear the fees and
               expenses of any additional counsel retained by them, but, in case
               you do not elect to assume the defense or any such suit, you
               shall reimburse Investor Services and such officers, directors or
               controlling person or persons, defendant of defendants in such
               suit, for the reasonable fees and expenses of any counsel
               retained by them. You agree promptly to notify Investor Services
               of the commencement of any litigation or proceedings against it
               in connection with the offer, issue and sale of any shares.

          (b)  Investor Services will indemnify and hold harmless you and each
               of your directors and officers and each person, if any, who
               controls you within the meaning of Section 15 of the 1933 Act,
               against any loss, liability, damages, claim or expense (including
               the reasonable cost of investigating or defending any alleged
               loss, liability, damages, claim or expense and reasonable counsel
               fees incurred in connection therewith), arising by reason of any
               person's acquiring any Shares, which may be based upon the 1933
               Act or any other statute or common law, and which (i) may be
               based upon any wrongful act by Investor Services, any of its
               employees or representatives, or (ii) may be based upon any
               untrue statement or alleged untrue statement of a material fact
               contained in a registration statement or prospectus covering
               Shares or any amendment thereof or supplement thereto or the
               omission or alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading unless such statement or omission was made
               in reliance upon information furnished to Investor Services or
               the Fund by you or (iii) may be based on any untrue statement or
               alleged untrue statement of a material fact contained in a
               registration statement or prospectus covering insurance products
               sold by you, or any amendment or supplement thereto, or the
               omission or alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statement
               or statements therein not misleading, if such statement or
               omission was made in reliance upon information furnished to you
               by or on behalf of Investor Services or the Fund; provided,
               however, that in no case (i) is the indemnity by Investor
               Services in favor of any person indemnified to be deemed to
               protect you or any such person against any liability to which you
               or any such person would otherwise be subject by reason of
               willful misfeasance, bad faith or gross negligence in the
               performance of your or his duties by reason of your or his
               reckless disregard of your or his obligations and duties under
               this Agreement, or (ii) is Investor Services to be liable under
               its indemnity agreement contained in this paragraph with respect
               to any claim made against you or any person indemnified unless
               you or such person, as the case may be, shall have notified
               Investor Services in writing within a reasonable time after the
               summons or other first legal process giving information of the
               nature of the claim shall have been served upon you or upon such
               person (or after you or such person shall have received notice of
               such service on any designated agent), but failure to notify
               Investor Services of any such claim shall not relieve Investor
               Services from any

                                       7
<PAGE>
 
               liability to which Investor Services may have to you or any
               person against whom such action is brought otherwise than on
               account of its indemnity agreement contained in this paragraph.
               Investor Services shall be entitled to participate, at its own
               expense, in the defense, or, if it so elects, to assume the
               defense of any suit brought to enforce any such liability, but,
               if it elects to assume the defense, such defense shall be
               conducted by counsel chosen by Investor Services and satisfactory
               to you, or to your officers or directors, or to any controlling
               person or persons, defendant or defendants in the suit. In the
               event that Investor Services assumes the defense of any such suit
               and retains such counsel, you or such officers or directors or
               controlling person or persons, defendant or defendants in the
               suit, shall bear the fees and expenses of any additional counsel
               retained by you, but, in case Investor Services does not elect to
               assume the defense of any such suit, Investor Services shall
               reimburse you and such officers, directors or controlling person
               or persons, defendant or defendants in such suit, for the
               reasonable fees and expenses of any counsel retained by you.
               Investor Services agrees promptly to notify you of the
               commencement of any litigation or proceedings against it in
               connection with the offer, issue and sale of any Shares.

     9.   The indemnities, representations, warranties, covenants and agreements
          of each party to this Agreement as set forth in this Agreement will
          remain in full force and effect regardless of any investigation made
          by or on behalf of either of such parties or any of their respective
          officers, directors, partners or any controlling person, and will
          survive delivery of and payment for the Shares.

     10.  Any provision of this Agreement which may be determined by competent
          authority to be prohibited or unenforceable in any jurisdiction shall,
          as to such jurisdiction, be ineffective to the extent of such
          prohibition or unenforceability without invalidating the remaining
          provisions hereof, and any such prohibition or unenforceability in any
          jurisdiction shall not invalidate or render unenforceable such
          provision in any other jurisdiction.  To the extent permitted by
          applicable law, each party hereto waives any provision of law which
          renders any provision hereof prohibited or unenforceable in any
          respect.

     11.  This Agreement, as amended by the letter agreement dated February 3,
          1995, as amended, together constitutes the entire agreement among the
          parties concerning the subject matter hereof, and supersede any and
          all prior understandings.

                                       8

     12.  This Agreement shall automatically terminate in the event of its
          assignment.  This Agreement may be terminated at any time by either
          party by written notice given to the other party, provided that the
          obligation of each party to indemnify the other party pursuant to
          paragraph 8 hereof shall apply with respect to any Shares sold before
          or after such termination.

     13.  Any notice hereunder shall be duly given if mailed or telegraphed to
          the other party hereto at the address specified below.  This Agreement
          shall be governed by and construed in accordance with the laws of The
          Commonwealth of Massachusetts.

     14.  This Agreement may be executed in any number of counterparts which,
          taken together shall constitute one and the same instrument.  This
          Agreement shall become effective upon receipt by us of your acceptance
          hereof.

     15.  This Agreement may not be modified or amended except by a written
          instrument duly executed by the parties hereto.

                        FORM OF REIMBURSEMENT AGREEMENT

     REIMBURSEMENT AGREEMENT (the "Agreement") made by and between SCUDDER
KEMPER INVESTMENTS, INC., a Delaware corporation ("Scudder Kemper"), with a
principal place of business in Boston, Massachusetts and USAA LIFE INSURANCE
COMPANY, a Texas corporation (the "Company"), with a principal place of business
in San Antonio, Texas on behalf of the Separate Account of USAA Life Insurance
Company, a separate account of the Company, and any other separate account of
the Company as designated by the Company from time to time, upon written notice
to the Fund in accordance with Section 8 herein (the "Account").

     WHEREAS, Scudder Kemper has caused to be organized Scudder Variable Life
Investment Fund (the "Fund"), a Massachusetts business trust created under a
Declaration of Trust dated March 15, 1985, as amended, the beneficial interest
in which is divided into several series, each designated a "Portfolio" and
representing the interest in a particular managed portfolio of securities; and

     WHEREAS, the purpose of the Fund is to act as the investment vehicle for
the separate accounts established for variable life insurance policies and
variable annuity contracts to be offered by insurance companies which have
entered into reimbursement agreements substantially identical to this Agreement;
and

     WHEREAS, the parties desire to express their agreement as to certain
matters;

     NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements hereinafter contained, the parties hereto agree as follows:
<PAGE>
 
     1.  Additional Definitions.
         ---------------------- 
     For purposes of this Agreement, the following definition shall apply:

     (a)  "Shares" means shares of beneficial interest, without par value, of
          any Portfolio, now or hereafter created, of the Fund.

     2.   Access to Other Products.
          ------------------------ 

     Scudder Kemper shall permit the Company to participate in any registered
investment company other than the Fund which is intended as the funding vehicle
for insurance products and for which Scudder Kemper or an affiliate of Scudder
Kemper acts as investment adviser, on the same basis as other insurance
companies are permitted to participate in such a registered investment company.
This provision shall not require Scudder Kemper to make available to the Company
shares of any investment company which is organized solely as the funding
vehicle for insurance products offered by a single insurance company or a group
of affiliated insurance companies.

     3.   Right to Review and Approve Sales Materials.
          ------------------------------------------- 

     The Company shall furnish, or shall cause to be furnished, to Scudder
Kemper or its designee, at least twenty days prior to its intended use, each
piece of promotional material in which Scudder Kemper or the Fund is named.  No
such material shall be used unless Scudder Kemper or its designee shall have
approved such use in writing, or twenty days shall have elapsed without
approval, rejection or objection since receipt by Scudder Kemper or its designee
of such material.

                                       2

     Scudder Kemper shall furnish, or shall cause to be furnished, to the

such material.

     4.   Sales Organization Meetings.
          --------------------------- 

     Representatives of Scudder Kemper or its designee shall meet with the sales
organizations of the Company at such reasonable times and places as may be
agreed upon by the Company and Scudder Kemper or its designee for the purpose of
educating sales personnel about the Fund.

     5.   Duration.
          -------- 

     This Agreement shall continue in effect for five (5) years from the date of
its execution, except that the obligation of each party hereto to indemnify the
other party hereto shall continue with respect to all losses, claims, damages,
liabilities or litigation based upon the acquisition of Shares purchased as the
funding vehicle for any variable life insurance policy or variable annuity
contract issued by the Company or any affiliated insurance company.

     6.   Indemnification.
          --------------- 

     (a)  The Company agrees to indemnify and hold harmless Scudder Kemper and
each of its directors and officers and each person, if any, who controls Scudder
Kemper within the meaning of Section 15 of the Securities Act of 1933 (the
"Act") against any and all

                                       3
<PAGE>
 
losses, claims, damages, liabilities or litigation (including legal and other
expenses) to which Scudder Kemper or such directors, officers or controlling
person may become subject under the Act, under any other statute, at common law
or otherwise, arising out of the acquisition of any Shares by any person which
(i) may be based upon any wrongful act by the Company, any of its employees or
representatives, any affiliate of or any person acting on behalf of the Company
or a principal underwriter of its insurance products, or (ii) may be based upon
any untrue statement or alleged untrue statement of a material fact contained in
a registration statement or prospectus covering Shares or any amendment thereof
or supplement thereto or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading if such a statement or omission was made in reliance upon
information furnished to Scudder Kemper or the Fund by the Company, provided,
however, that in no case (i) is the Company's indemnity in favor of a director
or officer or any other person deemed to protect such director or officer or
other person against any liability to which any such person would otherwise be
subject by reason of willful misfeasance, bad faith, or gross negligence in the
performance of his duties or by reason of his reckless disregard of obligations
and duties under this Agreement or (ii) is the Company to be liable under its
indemnity agreement contained in this Paragraph 6 with respect to any claim made
against Scudder Kemper or any person indemnified unless Scudder Kemper or such
person, as the case may be, shall have notified the Company in writing pursuant
to Paragraph 8 within a reasonable time after the summons or other first legal
process

                                       4
<PAGE>
 
giving information of the nature of the claims shall have been served upon
Scudder Kemper or upon such person (or after Scudder Kemper or such person shall
have received notice of such service on any designated agent), but failure to
notify the Company of any such claim shall not relieve the Company from any
liability which it has to Scudder Kemper or any person against whom such action
is brought otherwise than on account of the indemnity agreement contained in
this Paragraph 6. The Company shall be entitled to participate, at its own
expense, in the defense, or, if it so elects, to assume the defense of any suit
brought to enforce any such liability, but, if it elects to assume the defense,
such defense shall be conducted by counsel chosen by it and satisfactory to
Scudder Kemper, to its officers and directors, or to any controlling person or
persons, defendant or defendants in the suit. In the event that the Company
elects to assume the defense of any such suit and retain such counsel, Scudder
Kemper, such officers and directors or controlling person or persons, defendant
or defendants in the suit, shall bear the fees and expenses of any additional
counsel retained by them, but, in case the Company does not elect to assume the
defense of any such suit, the Company will reimburse Scudder Kemper, such
officers and directors or controlling person or persons, defendant or defendants
in such suit, for the reasonable fees and expenses of any counsel retained by
them. The Company agrees promptly to notify Scudder Kemper pursuant to Paragraph
8 of the commencement of any litigation or proceedings against it in connection
with the issue and sale of any Shares.

                                       5
<PAGE>
 
     (b)  Scudder Kemper agrees to indemnify and hold harmless the Company and
each of its directors and officers and each person, if any, who controls the
Company within the meaning of Section 15 of the Act against any and all losses,
claims, damages, liabilities or litigation (including legal and other expenses)
to which the Company or such directors, officers or controlling persons may
become subject under the Act, under any other statute, at common law or
otherwise, arising out of the acquisition of any Shares by any person which (i)
may be based upon any wrongful act by Scudder Kemper, any of its employees or
representatives or a principal underwriter of the Fund, or (ii) may be based
upon any untrue statement or alleged untrue statement of a material fact
contained in a registration statement or prospectus covering Shares or any
amendment thereof or supplement thereto or the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading if such statement or omission was made in
reliance upon information furnished to the Company by Scudder Kemper; provided,
however, that in no case (i) is Scudder Kemper's indemnity in favor of a
director or officer or any other person deemed to protect such director or
officer or other person against any liability to which any such person would
otherwise be subject by reason of willful misfeasance, bad faith, or gross
negligence in the performance of his duties or by reason of his reckless
disregard of obligations and duties under this Agreement or (ii) is Scudder
Kemper to be liable under its indemnity agreement contained in this Paragraph 6
with respect to any claims made against the Company or any such director,
officer or controlling person unless it or such director, officer

                                       6
<PAGE>
 
or controlling person, as the case may be, shall have notified Scudder Kemper in
writing pursuant to Paragraph 8 within a reasonable time after the summons or
other first legal process giving information of the nature of the claim shall
have been served upon it or upon such director, officer or controlling person
(or after the Company or such director, officer or controlling person shall have
received notice of such service on any designated agent), but failure to notify
Scudder Kemper of any claim shall not relieve it from any liability which it may
have to the Company or any person against whom such action is brought otherwise
than on account of its indemnity agreement contained in this Paragraph 6.
Scudder Kemper will be entitled to participate at its own expense in the
defense, or, if it so elects, to assume the defense of any suit brought to
enforce any such liability, but if Scudder Kemper elects to assume the defense,
such defense shall be conducted by counsel chosen by it and satisfactory to the
Company, its directors, officers or controlling person or persons, defendant or
defendants, in the suit. In the event Scudder Kemper elects to assume the
defense of any such suit and retain such counsel, the Company, its directors,
officers or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them,
but, in case Scudder Kemper does not elect to assume the defense of any such
suit, it will reimburse the Company or such directors, officers or controlling
person or persons, defendant or defendants in the suit, for the reasonable fees
and expenses of any counsel retained by them. Scudder Kemper agrees promptly to
notify the Company pursuant to Paragraph 8 of the commencement of any litigation
or proceedings against it or any

                                       7
<PAGE>
 
of its officers or directors in connection with the issuance or sale of any
Shares.

     (c) Scudder Kemper agrees to indemnify and hold harmless the Company and
each of its directors and officers against any and all losses, claims, damages,
liabilities or litigation arising from the imposition of additional federal
income taxes on the Company or any policyholder solely as a result of a Final
Determination that any Portfolio has failed (x) to comply with the
diversification requirements of section 817(h) of the Internal Revenue Code of
1986, as amended (the "Code"), relating to the diversification requirements for
variable annuity, endowment and life insurance contracts, or (y) to qualify as a
regulated investment company within the meaning of section 851 of the Code;
provided, however, that (i) Scudder Kemper shall have no liability under this
Paragraph 6(c) if such failure is caused by a third party who is not an employee
or agent of Scudder Kemper (e.g., the Fund's custodian or another service
provider), and (ii) in no case is Scudder Kemper's indemnity under this
Paragraph 6(c) deemed to protect any person against any liability to which that
person would otherwise be subject by reason of willful misfeasance, bad faith or
gross negligence in the performance of that person's duties or by reason of
reckless disregard by that person of obligations under this Agreement.

          The Company agrees that if the Internal Revenue Service asserts in
writing in connection with any governmental audit or review of the Company or,
to the Company's knowledge, of any policyholder, that any Portfolio has failed
to comply with the diversification requirements of section 817(h) of the Code or
the

                                       8
<PAGE>
 
Company otherwise becomes aware of any facts that could give rise to any
claim against Scudder Kemper as a result of such a failure or alleged failure,
(i) the Company shall promptly notify Scudder Kemper of such assertion or
potential claim; (ii) the Company shall consult with Scudder Kemper as to how to
minimize any liability that may arise as a result of such failure or alleged
failure; (iii) the Company shall use its best efforts to minimize any liability
of Scudder Kemper for indemnification resulting from such failure, including,
without limitation, demonstrating, pursuant to Treasury Regulations Section
1.817-5(a) (2), to the Commissioner of the Internal Revenue Service that such
failure was inadvertent; (iv) the Company shall permit Scudder Kemper and its
legal and accounting advisors to participate in any conferences, settlement
discussions or other administrative or judicial proceedings or contests
(including judicial appeals thereof) with the Internal Revenue Service, any
policyholder or any other claimant regarding any claims that could give rise to
indemnification by Scudder Kemper as a result of such a failure or alleged
failure; (v) any written materials to be submitted by the Company to the
Internal Revenue Service, any policyholder or any other claimant in connection
with any of the foregoing proceedings or contests (including, without
limitation, any such materials to be submitted to the Internal Revenue Service
pursuant to Treasury Regulations Section 1.817-5(a) (2)), (a) shall be provided
by the Company to Scudder Kemper (together with any supporting information or
analysis) at least 10 business days prior to the day on which such proposed
materials are to be submitted and (b) shall not be submitted by the Company to
any such person without the express

                                       9
<PAGE>
 
written consent of Scudder Kemper, which shall not be unreasonably withheld;
(vi) the Company shall provide Scudder Kemper and its advisors with such
cooperation as Scudder Kemper shall reasonably request (including, without
limitation, by permitting Scudder Kemper and its accounting and legal advisors
to review the relevant books and records of the Company) in order to facilitate
Scudder Kemper's review of any written submissions provided to it pursuant to
the preceding clause or its assessment of the validity or amount of any claim
against it arising from such a failure or alleged failure; (vii) the Company
shall not with respect to any claim of the IRS or any policyholder that would
give rise to a claim for indemnification against Scudder Kemper (a) compromise
or settle any claim, (b) accept any adjustment on audit, or (c) forego any
allowable judicial appeals, without the express written consent of Scudder
Kemper, which shall not be unreasonably withheld, provided that the Company
shall not be required to appeal any adverse judicial decision unless Scudder
Kemper shall have provided an opinion of independent counsel to the effect that
a reasonable basis (consistent with Formal Opinion 85-352 of the American Bar
Association) exists for taking such appeal; and (viii) Scudder Kemper shall have
no liability as a result of such failure or alleged failure if the Company fails
to comply with any of the foregoing clauses (i) through (vii). Should Scudder
Kemper refuse to give its written consent to any compromise or settlement of any
claim or liability hereunder, the Company may, in its discretion, authorize
Scudder Kemper to act in the name of the Company in, and to control the conduct
of, such conferences, discussions, proceedings, contests or appeals and all
administrative or judicial

                                       10
<PAGE>
 
appeals thereof, and in that event Scudder Kemper shall bear the fees and
expenses associated with the conduct of the proceedings that it is so authorized
to control.

     For purposes of this Paragraph 6(c), "Final Determination" shall mean, with
respect to any claim, a settlement of such claim (including the acceptance of an
adjustment proposed by the Internal Revenue Service) or a decision of a court of
competent jurisdiction with respect to such claim that has become final after
either the (i) exhaustion of allowable appeals or (2) expiration of the time to
take any such appeal with respect to the claim.

Scudder Kemper Investments, Inc.
Scudder Investor Services, Inc.
Scudder Variable Life Investment Fund
2 International Place
Boston, MA  02110

Executives:

          We are writing to augment and clarify certain of the terms and
conditions of:  (1) the participation agreement, dated February 3, 1995, by and
between USAA Life Insurance Company ("USAA Life"), on behalf of the Separate
Account of USAA Life Insurance Company ("Separate Account") and the Life
Insurance Separate Account of USAA Life Insurance Company ("Life Insurance
Separate Account"), and the Scudder Variable Life Investment Fund ("Fund")
(hereinafter "Participation Agreement"); (2) the reimbursement agreement, dated
February 3, 1995, by and between USAA Life and Scudder, Stevens & Clark ("SS&C")
(hereinafter "Reimbursement Agreement"); and (3) the participating contract and
policy agreement, dated February 3, 1995, by and between USAA Investment
Management Company ("IMCO") and Scudder Investor Services, Inc. ("SIS")
(hereinafter "Policy Agreement").

          Unless otherwise noted, the provisions set out below are intended to
apply to the Participation Agreement, Reimbursement Agreement and the Policy
Agreement (collectively, the "Agreements") and, to the extent contrary to or
inconsistent with any provision in any Agreement, shall modify such provision.
The headings used herein are for convenience of reference only.

          Kindly acknowledge your acceptance and agreement to the following by
affixing your signature to the last page of this letter.


AVAILABLE PORTFOLIOS.
- -------------------- 

          The Fund's Capital Growth Portfolio ("Portfolio" or "Capital Growth
Portfolio") is the only Fund series that USAA Life currently intends to make
available for investment through the Separate Account and the Life Insurance
Separate Account.  Accordingly, any obligations of USAA Life with respect to
capital contributions or expense reimbursements required to be made under the
Participation Agreement shall be limited to the Capital Growth Portfolio, until
such time as USAA Life notifies the Fund that it intends to use one or more
additional portfolios.

PURCHASES AND REDEMPTIONS.
- ------------------------- 

     1.  Timely Pricing and Orders.  The Fund or its designated agent will use
all commercially reasonable efforts to provide to USAA Life the closing net
asset value and any dividend and capital gain information for the Portfolio by
5:15 p.m., Central time on each Business Day.  "Business Day" shall mean any day
on which the Fund calculates the net asset value of its Funds pursuant to rules
of the Securities and Exchange Commission and as described in the Fund's
Prospectus.  USAA Life will use these data to calculate unit values, which in
turn will be used to process transactions that receive that same Business Day's
Separate Account or Life Insurance Separate Account unit value.  Such Separate
Account or Life Insurance Separate Account processing will be done the same
evening, and corresponding orders with respect to Fund shares will be placed the
morning of the following Business Day.  USAA Life will use all commercially
reasonable efforts to place such orders with the Fund by 9 a.m., Central time.

     2.  Timely Payments.  USAA Life or its designated agent will transmit
orders for purchases and redemptions of Fund shares to SIS, and will wire
payment for net purchases to a custodial account designated by the Fund on the
same day as the order for Fund shares is placed, to the extent practicable.
Payment for net redemptions will be wired by the Fund to an account designated
by USAA Life on the same day as the order is placed, to the extent practicable,
but in any event within such reasonably practicable period of time after the
order is placed as would enable USAA Life to pay redemption proceeds in
compliance with Section 22(e) of the Investment Company Act of 1940.

     3.  Applicable Price.  The Fund shall effect any orders to purchase or
redeem Portfolio shares that USAA Life submits on behalf of the Separate
Account, based on transactions under variable annuity contracts issued by USAA
Life ("Contracts"), and on behalf of the Life Insurance Separate Account, based
on transactions under variable life insurance policies ("Policies"), at the
Portfolio's net asset value per share as of the close of business on the
Business Day the order is received by USAA Life or its designee, acting as agent
for the Fund, provided that such order is received prior to the time as of which
the Fund calculates net asset value on that Business Day.  If such order is
received after that time, the order will be effected at the Portfolio's net
asset value as of the close of business on the next Business Day.  Any orders to
purchase shares of an available Fund not based on transactions under Contracts
or Policies will be effected at the Fund's net asset value per share next
computed after the order is received by the Fund.

     4.  Redemptions.  The Fund shall redeem for cash from USAA Life those full
or fractional shares of the Portfolio that USAA Life requests from time to time.

REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS.
- ------------------------------------------- 

     USAA Life, on behalf of the Separate Account and the Life Insurance
Separate Account, hereby elects to reinvest all dividends and capital gains
distributions in additional shares of the Capital Growth Portfolio at the net
asset values on the payment date of such dividends and capital gains
distributions until USAA Life otherwise notifies the Fund in writing.  USAA Life
reserves the right to revoke this election and to receive all such dividends and
capital gain distributions in cash.  The Fund shall promptly notify USAA Life of
the number of shares so issued as payment of such dividends and distributions.


AMENDMENT TO POLICY AGREEMENT.
- ----------------------------- 

     As an additional inducement for IMCO to enter into the Policy Agreement,
SIS hereby agrees with IMCO as follows:

     (1) in connection with Sections 6 and 12 of the Policy Agreement, SIS will
     give IMCO thirty days' written notice before suspending sales or
     withdrawing the offering of Shares (as defined in the Policy Agreement) or
     terminating the Policy Agreement, except that sales of Shares may be
     suspended or the offering of Shares withdrawn or the Policy Agreement
     terminated without notice (i) if the continued offering or sale of Shares
     would violate any applicable statute or regulation, order or decree of any
     court, governmental agency or self-regulatory organization having
     jurisdiction, or (ii) if in the sole discretion of the Trustees of the
     Fund, including a majority of those Trustees who are not "interested
     persons" as defined in the Investment Company Act of 1940, as amended, of
     the Trust or of its investment adviser, such action is determined to be
     necessary in the best interests of the Shareholders of the Portfolio.

     (2) no unilateral amendment pursuant to Section 6 of the Policy Agreement
     shall be effective against IMCO unless it is accompanied by a written
     notice from SIS stating that the amendment is necessary to prevent the
     continued offering or sale of Shares from violating any applicable statute
     or regulation, order or decree of any court, governmental agency or self-
     regulating organization having jurisdiction.

FUND MATERIALS.
- -------------- 

     The Fund, at its expense, shall provide USAA Life or its designee with
camera ready copy or computer diskette versions of all prospectuses (including
supplements thereto), statements of additional information, annual and semi-
annual reports, and proxy materials (collectively, "Fund Materials"), to be
printed and distributed by USAA Life or IMCO to existing and prospective
Contract or Policy owners, as appropriate.  USAA Life agrees to bear the cost of
printing and distributing such Fund Materials.


TAX MATTERS.
- ----------- 

     1.  The Fund, SS&C, or SIS will notify USAA Life immediately upon having a
reasonable basis for believing that the Portfolio has ceased to comply with the
requirements of Section 817(h) of the Internal Revenue Code of 1986, as amended
("Code") or that the Portfolio might not so comply in the future.  In connection
with a failure to comply with the Section 817(h) diversification requirements,
SS&C shall cooperate with USAA Life by providing it with full explanation as to
the circumstances that caused the failure, and the reasons why the failure was
inadvertent.

     2.  The limitation against liability set out in paragraph 6(c)(viii) of the
Reimbursement Agreement shall apply only where it can be shown that the failure
of USAA Life to comply with clauses 6(c)(i) through (vii) materially contributed
to the liability.

     3.  Each Agreement shall terminate, at the option of USAA Life or IMCO, as
the case may be, in the event of a non-curable failure by the Portfolio to
comply with the provisions of Subchapter M or Section 817(h) of the Code.  To
the extent that any Agreement by its terms provides for one or more rights or
obligations thereunder to survive the termination of that Agreement, those
provisions shall survive the termination of that Agreement under this paragraph.


MISCELLANEOUS.
- ------------- 

     (a)  The Fund, SS&C, and SIS agree to make available to USAA Life and its
affiliates, to the extent permitted by applicable law, any arrangement for
utilization of the Portfolio, which arrangement has been or will be made
generally available to any other life insurance company or any affiliate of a
life insurance company.

     (b) This Agreement shall be construed and the provisions hereof interpreted
under and in accordance with the laws of the Commonwealth of Massachusetts.

     (c)  The name "Scudder Variable Life Investment Fund" is the designation of
the Trustees for the time being under a Declaration of Trust dated March 15,
1985, as amended, and all persons dealing with the Fund must look solely to the
property of the Fund for the enforcement of any claims against the Fund as
neither the Trustees, officers, agents or shareholders assume any personal
liability for obligations entered into on behalf of the Fund.  No Portfolio
shall be liable for any obligations properly attributable to any other
Portfolio.

                            PARTICIPATION AGREEMENT


     THIS AGREEMENT, made and entered into as of the 16th day of December, 1994
and amended March 16, 1998 ("Agreement"), by and among USAA Life Insurance
Company, a Texas life insurance company ("USAA Life"), on behalf of itself, the

"Trust"); Fred Alger Management, Inc., a New York corporation ("Adviser"), the
Trust's investment adviser; and Fred Alger & Company, Incorporated, a Delaware
corporation ("Distributor"), the Trust's principal underwriter (collectively,
the "Parties").


                                WITNESSETH THAT:

     WHEREAS, USAA Life will be the issuer of certain variable annuity contracts
of USAA Life that are the subject of USAA Life's Form N-4 registration statement
filed with the Securities and Exchange commission ("SEC"), File No. 33-82268
(the "Contracts"); and

     WHEREAS, USAA Life will be the issuer of certain flexible premium variable
universal life insurance policies that are the subject of USAA Life's Form S-6
and Form N-8B-2 registration statements filed with the SEC, File No. 333-45343
and 811-08625, respectively, (the "Policy" or "Policies"); and

     WHEREAS, USAA Life will fund the Contracts and Policies through the
Separate Account and Life Insurance Separate Account, respectively, each of
which currently consists of seven subaccounts ("Fund Accounts"; reference herein
to the "Separate Account" or "Life Insurance Separate Account" includes
reference to each Fund Account to the extent the context requires); and

     WHEREAS, USAA Life will serve as the depositor of the Separate Account and
the Life Insurance Separate Account, each of which is a unit investment trust
registered as an investment company under the Investment Company Act of 1940
(the "1940 Act"), and the security interests deemed to be issued by the Separate
Account under the Contracts and the Life Insurance Separate Account under the
Policies will be registered as securities under the Securities Act of 1933 (the
"1933 Act"); and

     WHEREAS, the Trust is registered with the SEC as an open-end management
investment company under the 1940 Act, consisting of six separate series
("Series") whose shares are registered under the 1933 Act; and

     WHEREAS, the Trust and Distributor will make shares of each Series listed
on Schedule A hereto (each, a "Portfolio"; reference herein to the "Trust"
includes reference to each Portfolio to the


                                       1
<PAGE>
 
extent the context requires) and made part hereof, available for purchase by the
Separate Account and the Life Insurance Separate Account; and

     WHEREAS, the Trust's Alger American Growth Portfolio ("Growth Portfolio")
is currently the only Portfolio that USAA Life intends to utilize as an
investment medium for the benefit of the owners of the Contracts (the "Contract
owners") or Policies ("Policy owners") who have allocated Contract or Policy
value to the Fund Account corresponding to that Portfolio;

     NOW, THEREFORE, in consideration of the mutual benefits and promises
contained herein, the Parties hereto agree as follows:


                       Section 1.  Available Portfolios
                        ---------------------------------


     1.1  Growth Portfolio.

     The Trust and Distributor will make shares in the Growth Portfolio
available to USAA Life for purchase and redemption at net asset value and with
no sales charges, subject to the terms and conditions of this Agreement.


     1.2  Addition or Deletion of Portfolios.

     The Parties hereto may agree, from time to time, to add other Trust
Portfolios to provide additional funding media for the Contracts and Policies,
or to delete, combine, or modify existing Portfolios, by amending Schedule A
hereto.  Upon such amendment to Schedule A, any applicable reference to a
Portfolio, the Trust, or its shares herein shall include a reference to any such
additional Portfolio.
 

     1.3  No Sales to the General Public.

     The Trust and Distributor represent and warrant that no shares of any
Portfolio have been or will be sold to the general public.


                                       2

                      Section 2.  Processing Transactions
                      ------------------------------------

     2.1  Timely Pricing and Orders.

     The Trust or its designated agent will provide closing net asset value,
dividend and capital gain distribution information for each Portfolio to USAA
Life at the close of trading on each day on which (a) the New York Stock
Exchange is open for regular trading, (b) the Trust calculates the Portfolio's
net asset value and (c) USAA Life is open for business ("Business Day").  The
Trust or its designated agent will use its best efforts to provide this
information by 5:15 p.m., Central time.  USAA Life will use these data to
calculate unit values, which in turn will be used to process transactions that
receive that same Business Day's Separate Account or Life Insurance Separate
Account unit value.  Such Separate Account or Life Insurance Account processing
will be done the same evening, and corresponding orders with respect to Trust
shares will be placed the morning of the following Business Day.  USAA Life will
use its best efforts to place such orders with the Trust by 9 a.m., Central
time.

     It is understood and agreed that the Trustees of the Trust may refuse to
sell shares of any Portfolio to any person, or suspend or terminate the offering
of shares of any Portfolio if such action is required by law or by regulatory
authorities having jurisdiction or if, in the sole discretion of the Trustees
acting in good faith and in light of their fiduciary duties under federal and
any applicable state laws, such action is deemed in the best interests of the
shareholders of such Portfolio.


     2.2  Timely Payments.

     USAA Life will transmit orders for purchases and redemptions of Trust
shares to Distributor, and will wire payment for net purchases to a custodial
account designated by the Trust on the same day as the order for Trust shares is
placed, to the extent practicable.  Payment for net redemptions will be wired by
the Trust to an account designated by USAA Life on the same day as the order is
placed, to the extent practicable, and in any event be made within five calendar
days after the date the order is placed in order to enable USAA Life to pay
redemption proceeds within the time specified in Section 22(e) of the 1940 Act.


     2.3  Applicable Price.

     The Parties agree that Portfolio share purchase and redemption orders that
result from Contract or Policy owner purchase payments, surrenders, partial
surrenders, partial withdrawals, routine withdrawals of charges, loans, loan
repayments, payment of benefit proceeds at death or Policy maturity, or requests
for other transactions under the Contracts or Policies that USAA Life receives
prior to the close of regular trading on the New York Stock Exchange on a
Business Day, will be executed at the net asset values as determined as of the
close of regular trading on the New


                                       3
<PAGE>
 
York Stock Exchange on that Day, which generally will be the Business Day prior
to Distributor's receipt of the corresponding orders for purchases and
redemptions of Portfolio shares. USAA Life or its designee shall act as the
Trust's agent for receipt of such orders. All other purchases and redemptions of
Portfolio shares by USAA Life will be effected at the net asset values next
computed after receipt by Distributor of the order therefor, and such orders
will be irrevocable.


     2.4  Dividends and Distributions.

     The Trust will furnish notice promptly to USAA Life of any income dividends
or capital gain distributions payable on the shares of any Portfolio.  USAA Life
hereby elects to reinvest all dividends and capital gains distributions in
additional shares of the corresponding Portfolio at the ex-dividend date net
asset values until USAA Life otherwise notifies the Trust in writing, it being
agreed by the Parties that the ex-dividend date and the payment date with
respect to any dividend or distribution will be the same Business Day.  USAA
Life reserves the right to revoke this election and to receive all such income
dividends and capital gain distributions in cash.  The Trust shall notify USAA
Life of the number of shares so issued as payment of such dividends and
distributions.


     2.5  Book Entry.

     Issuance and transfer of Trust shares will be by book entry only.  Stock
certificates will not be issued to USAA Life.  Shares ordered from the Trust on
behalf of the Separate Account will be recorded in an appropriate title for USAA
Life, on behalf of its Separate Account.  Shares ordered from the Trust on
behalf of the Life Insurance Separate Account will be recorded in an appropriate
title for USAA Life, on behalf of its Life Insurance Separate Account.

                         Section 4.  Legal Compliance
                         -----------------------------


     4.1  Tax Laws.

     (a) The Trust represents and warrants that each Portfolio is currently
qualified as a regulated investment company ("RIC") under Subchapter M of the
Internal Revenue Code of 1986, as amended (the "Code"), and represents that it
will use its best efforts to qualify and to maintain qualification of each
Portfolio as a RIC and the Trust, Adviser or Distributor will notify USAA Life
immediately upon having a reasonable basis for believing that a Portfolio has
ceased to so qualify or that it might not so qualify in the future.

     (b) USAA Life represents that it believes, in good faith, that the
Contracts and Policies will be treated as annuity contracts and life insurance
policies, respectively, under applicable provisions of the Code and that it will
use its best efforts to maintain such treatment; USAA Life will notify the Trust
and Distributor immediately upon having a reasonable basis for believing that
any of the Contracts or Policies have ceased to be so treated or that they might
not be so treated in the future.

     (c) The Trust represents that it will use its best efforts to comply and to
maintain each Portfolio's compliance with the diversification requirements set
forth in Section 817(h) of the Code and Section 1.817-5(b) of the regulations
under the Code, and the Trust, Adviser or Distributor will notify USAA Life
immediately upon having a reasonable basis for believing that a Portfolio has
ceased to so comply or that a Portfolio might not so comply in the future.

     (d) USAA Life represents that it believes, in good faith, that the Separate
Account and Life Insurance Separate Account are each a "segregated asset
account" and that interests in the Separate Account and Life Insurance Separate
Account are offered exclusively through the purchase of or transfer into a
"variable contract," within the meaning of such terms under Section 817 of the
Code and the regulations thereunder.  USAA Life will use its best efforts to
continue to meet such definitional requirements, and it will notify the Trust
and Distributor immediately upon having a

                                       6
<PAGE>
 
reasonable basis for believing that such requirements have ceased to be met or
that they might not be met in the future.

     (e) Adviser represents and warrants that it will manage each Portfolio in
compliance with its investment objectives, policies and restrictions as set
forth in the Trust Prospectus.  Adviser further represents and warrants that it
will manage each Portfolio as a RIC in compliance with Subchapter M and Section
817(h) of the Code and regulations thereunder.

     (f)  The Trust represents that it has adopted and will maintain procedures
for ensuring that the Trust is managed in compliance with Subchapter M and
Section 817(h) of the Code and regulations thereunder, and in a manner designed
to avoid the imposition of excise taxes under Section 4982 of the Code or any
other similar or successor provision.  On request, the Trust will also provide
USAA Life with such materials, cooperation and assistance as may be reasonably
necessary for USAA Life or any person designated by USAA Life to review from
time to time the procedures and practices of Adviser or any other provider of
services to the Trust for ensuring that the Trust is managed in compliance with
Subchapter M and Section 817(h) of the Code and regulations thereunder.  The
Parties hereto agree that the Trust shall not incur any unreasonable costs in
connection with the provision of any material, cooperation or assistance to USAA
Life pursuant to this paragraph.

     (g) Within 15 Business Days after the end of each calendar quarter, the
Adviser will furnish to USAA Life a letter confirming the Trust's compliance
with Subchapter M and Section 817(h) of the Code and regulations thereunder as
of the end of the applicable quarter, or, in the case of the last quarter in
each year, for the 12 months then ended.

     (h) In the event of any noncompliance or potential noncompliance with
Subchapter M or Section 817(h) of the Code and regulations thereunder, the Trust
will take such action as is necessary or appropriate to cure any noncompliance
during a grace period of 30 calendar days after the end of the calendar quarter
in which such noncompliance occurred.  If the Trust so cures the noncompliance,
it will furnish USAA Life with a report by the last day of such grace period
confirming the same.  If the Trust does not so cure the noncompliance regarding
its status as a RIC, the Trust will pursue those efforts necessary to enable
each affected Portfolio to qualify once again for treatment as a RIC in
compliance with Subchapter M.  If the Trust does not so cure the noncompliance
regarding its status under Section 817(h), the Trust will cooperate in good
faith with USAA Life's efforts to obtain a ruling and closing agreement, as
provided in Revenue Procedure 92-25 issued by the Internal Revenue Service (or
any applicable ruling or procedure subsequently issued by the Internal Revenue
Service), that the Trust satisfies Section 817(h) for the applicable period or
periods.

                     Section 5.  Mixed and Shared Funding
                     -------------------------------------


     5.1  General.

     The Trust represents and warrants that it has received an order from the
SEC exempting it from certain provisions of the 1940 Act and rules thereunder so
that the Trust may be available for investment by certain other entities,
including, without limitation, separate accounts funding variable life insurance
contracts ("Mixed Funding") and separate accounts of insurance companies
unaffiliated with USAA Life ("Shared Funding").  The Parties recognize that the
SEC has imposed terms and conditions for such orders that are substantially
identical to many of the provisions of this Section 5.  Sections 5.2 through 5.8
below shall apply, if and only if the Trust implements Mixed or Shared Funding,
pursuant to such an exemptive order or otherwise.


     5.2  Disinterested Trustees.

     The Trust agrees that its Board of Trustees shall at all times consist of
trustees a majority of whom (the "Disinterested Trustees") are not interested
persons of the Trust within the meaning of Section 2(a)(19) of the 1940 Act.


     5.3  Monitoring for Material Irreconcilable Conflicts.

     The Trust agrees that its Board of Trustees will monitor for the existence
of any material irreconcilable conflict between the interests of the
participants in all separate accounts of life insurance companies utilizing the
Trust, including the Separate Account.  USAA Life agrees to inform the Board of
Trustees of the Trust of the existence of or any potential for any such material
irreconcilable conflict of which it is aware.  The concept of a "material
irreconcilable conflict" is not defined by the 1940 Act or the rules thereunder,
but the Parties recognize that such a conflict may arise for a variety of
reasons, including, without limitation:

     (a) an action by any state insurance or other regulatory authority;

     (b) a change in applicable federal or state insurance, tax or securities
         laws or regulations, or a public ruling, private letter ruling, no-
         action or interpretative letter, or any similar action by insurance,
         tax or securities regulatory authorities;

     (c) an administrative or judicial decision in any relevant proceeding;

     (d) the manner in which the investments of any Portfolio are being managed;



                                      12
<PAGE>
 
     (e) a difference in voting instructions given by variable annuity
         contract and variable life insurance contract participants or by
         participants of different life insurance companies utilizing the Trust;
         or

     (f) a decision by a life insurance company utilizing the Trust to
         disregard the voting instructions of participants.

     Consistent with the SEC's requirements in connection with exemptive
proceedings of the type referred to in Section 5.1 hereof, USAA Life will assist
the Board of Trustees in carrying out its responsibilities by providing the
Board of Trustees with all information reasonably necessary for the Board of
Trustees to consider any issue raised, including information as to a decision by
USAA Life to disregard voting instructions of Participants.


     5.4  Conflict Remedies.

     (a) It is agreed that if it is determined by a majority of the members of
the Board of Trustees or a majority of the Disinterested Trustees that a
material irreconcilable conflict exists, USAA Life and the other life insurance
companies utilizing the Trust will, at their own expense and to the extent
reasonably practicable (as determined by a majority of the Disinterested
Trustees), take whatever steps are necessary to remedy or eliminate the material
irreconcilable conflict, which steps may include, but are not limited to:

    (i)  withdrawing the assets allocable to some or all of the separate        
         accounts from the Trust or any Portfolio and reinvesting such assets in
         a different investment medium, including another Portfolio of the
         Trust, or submitting the question whether such segregation should be
         implemented to a vote of all affected participants and, as appropriate,
         segregating the assets of any particular group (e.g., annuity contract
         owners or participants, life insurance contract owners or all contract
         owners and participants of one or more life insurance companies
         utilizing the Trust) that votes in favor of such segregation, or
         offering to the affected contract owners or participants the option of
         making such a change; and

    (ii) establishing a new registered investment company of the type defined
         as a "Management Company" in Section 4(3) of the 1940 Act or a new
         separate account that is operated as a Management Company.

    (b)  If the material irreconcilable conflict arises because of USAA Life's
decision to disregard Participant voting instructions and that decision
represents a minority position or would preclude a majority vote, USAA Life may
be required, at the Trust's election, to withdraw the Separate Account's or Life
Insurance Separate Account's investment in the Trust.  No charge or penalty will
be imposed as a result of such withdrawal.  Any such withdrawal must take place
within six months after the Trust gives notice to USAA Life that this provision
is being



                                      13
<PAGE>
 
implemented, and until such withdrawal Distributor and the Trust shall
continue to accept and implement orders by USAA Life for the purchase and
redemption of shares of the Trust.

     (c) If a material irreconcilable conflict arises because a particular state
insurance regulator's decision applicable to USAA Life conflicts with the
majority of other state regulators, then USAA Life will withdraw the Separate
Account's or Life Insurance Separate Account's investment in the Trust within
six months after the Trust's Board of Trustees informs USAA Life that it has
determined that such decision has created a material irreconcilable conflict,
and until such withdrawal Distributor and Trust shall continue to accept and
implement orders by USAA Life for the purchase and redemption of shares of the
Trust.

     (d) USAA Life agrees that any remedial action taken by it in resolving any
material irreconcilable conflict will be carried out at its expense and with a
view only to the interests of Participants.

     (e) For purposes hereof, a majority of the Disinterested Trustees will
determine whether or not any proposed action adequately remedies any material
irreconcilable conflict.  In no event, however, will the Trust or Distributor be
required to establish a new funding medium for any Contracts or Policies.  USAA
Life will not be required by the terms hereof to establish a new funding medium
for any Contracts or Policies if an offer to do so has been declined by vote of
a majority of Participants materially adversely affected by the material
irreconcilable conflict.


     5.5  Notice to USAA Life.

     The Trust will promptly make known in writing to USAA Life the Board of
Trustees' determination of the existence of a material irreconcilable conflict,
a description of the facts that give rise to such conflict and the implications
of such conflict.


     5.6  Information Requested by Board of Trustees.

     USAA Life and the Trust will at least annually submit to the Board of
Trustees of the Trust such reports, materials or data as the Board of Trustees
may reasonably request so that the Board of Trustees may fully carry out the
obligations imposed upon it by the provisions hereof, and said reports,
materials and data will be submitted at any reasonable time deemed appropriate
by the Board of Trustees.  All reports received by the Board of Trustees of
potential or existing conflicts, and all Board of Trustees actions with regard
to determining the existence of a conflict, notifying life insurance companies
utilizing the Trust of a conflict, and determining whether any proposed action
adequately remedies a conflict, will be properly recorded in the minutes of the
Board of Trustees or other appropriate records, and such minutes or other
records will be made available to the SEC upon request.


                                      14
<PAGE>
 
     5.7  Compliance with SEC Rules.

     If, at any time during which the Trust is serving as an investment medium
for variable life insurance policies, 1940 Act Rules 6e-3(T) or, if applicable,
6e-2 are amended or Rule 6e-3 is adopted to provide exemptive relief with
respect to mixed and shared funding, the Trust agrees that it will comply with
the terms and conditions thereof and that the terms of this Section 5 shall be
deemed modified if and only to the extent required in order also to comply with
the terms and conditions of such exemptive relief that is afforded by any of
said rules that are applicable.


     5.8  Requirements for Other Insurance Companies.

     The Trust will require that each insurance company utilizing the Trust
enter into an agreement with the Trust that contains in substance the same
provisions as are set forth in Sections 4.1(b), 4.1(d), 4.3(a), 4.4(b), 4.5(a),
5, 10 and 18(a) of this Agreement.



                            Section 6.  Termination

     6.1  Events of Termination.

     Subject to Section 6.4 below, this Agreement will terminate as to a
Portfolio:

     (a) at the option of USAA Life, Distributor or the Trust upon the approval
by (x) a majority of the Disinterested Trustees or (y) a majority vote of the
shares of the affected Portfolio that are held in the corresponding Fund Account
of the Separate Account or Life Insurance Separate Account (pursuant to the
procedures set forth in Section 10 of this Agreement for voting Trust shares in
accordance with Participant instructions); provided, however, that the approvals
described in clauses (x) and (y) above shall not be required if (1) the
aggregate account value under the Contracts or Policies is less than $25
million, respectively, at the date the notice of termination is delivered, and
(2) the notice of termination is delivered no earlier than the end of the 36th
full calendar month following the date this Agreement was amended ; or

     (b) at the option of the Trust upon institution of formal proceedings
against USAA Life or its affiliates by the NASD, the SEC, any state insurance
regulator or any other regulatory body regarding USAA Life's obligations under
this Agreement or related to the sale of the Contracts or Policies, the
operation of the Separate Account or the Life Insurance Separate Account, or the
purchase of the Trust shares, if, in each case, the Trust reasonably determines
that such proceedings, or the facts on which such proceedings would be based,
have a material likelihood of imposing

                                      15
<PAGE>
 
material adverse consequences on the Portfolio with respect to which the
Agreement is to be terminated; or

     (c) at the option of USAA Life upon institution of formal proceedings
against the Trust, Distributor, or Adviser by the NASD, the SEC, or any state
insurance regulator or any other regulatory body regarding the Trust's,
Distributor's or Adviser's obligations under this Agreement or related to the
operation or management of the Trust or the purchase of Trust shares, if, in
each case, USAA Life reasonably determines that such proceedings, or the facts
on which such proceedings would be based, have a material likelihood of imposing
material adverse consequences on USAA Life, or the Fund Accounts corresponding
to the Portfolio with respect to which the Agreement is to be terminated; or

     (d) at the option of any Party in the event that (i) the Portfolio's shares
are not registered and, in all material respects, issued and sold in accordance
with any applicable state or federal law or (ii) such law precludes the use of
such shares as an underlying investment medium of the Contracts or Policies
issued or to be issued by USAA Life; or

     (e) upon termination of the corresponding Fund Accounts' investment in the
Portfolio pursuant to Section 5 hereof; or

     (f) at the option of USAA Life if the Portfolio ceases to qualify as a RIC
under Subchapter M of the Code or under successor or similar provisions, or if
USAA Life reasonably believes that the Portfolio may fail to so qualify;

     (g) at the option of USAA Life if the Portfolio fails to comply with
Section 817(h) of the Code or with successor or similar provisions, or if USAA
Life reasonably believes that the Portfolio may fail to so comply; or

     (h) in the event of any change in the Portfolio's investment adviser or
investment practices, at the option of USAA Life if USAA Life reasonably
believes that such change will materially increase the risks incurred by USAA
Life or Participants; or

     (i) at the option of any Party if the Contracts or Policies issued by USAA
Life cease to qualify as annuity contracts or life insurance policies,
respectively, under the Code (other than by reason of the Portfolio's
noncompliance with Section 817(h) or Subchapter M of the Code) or if interests
in the Separate Account under the Contracts or in the Life Insurance Separate
Account under the Policies are not registered and, in all material respects,
issued or sold in accordance with any applicable state or federal law.

                         Section 10.  Voting Procedures
                         ------------------------------


     Subject to the cost allocation procedures set forth in Section 3 hereof,
USAA Life will distribute all proxy material furnished by the Trust to
Participants and will vote Trust shares in accordance with instructions received
from Participants.  USAA Life will vote Trust shares that are (a) not
attributable to Participants or (b) attributable to Participants, but for which
no instructions have been received, in the same proportion as Trust shares for
which said instructions have been received from Participants.  USAA Life agrees
that, with respect to the Policies, it will disregard Participant voting
instructions only to the extent it would be permitted to do so pursuant to Rule
6e-3(T)(b)(15)(iii) under the 1940 Act.  USAA Life agrees that, with respect to
the Contracts, it will disregard Participant voting instructions only to the
extent it would be permitted to do so pursuant to Rule 6e-3(T)(b)(15)(iii) under
the 1940 if the Contracts were variable life insurance policies subject to that
rule.  Other participating life insurance companies utilizing the Trust will be
responsible for calculating voting privileges in a manner consistent with that
of USAA Life, as prescribed by this Section 10.

     12.1 Of Trust, Distributor and Adviser by USAA Life.

     (a) Except to the extent provided in Sections 12.1(b) and 12.1(c), below,
USAA Life agrees to indemnify and hold harmless the Trust, Distributor and
Adviser, each of their trustees, directors and officers, and each person, if
any, who controls the Trust, Distributor or Adviser within the meaning of
Section 15 of the 1933 Act (collectively, the "Indemnified Parties" for purposes
of this Section 12.1) against any and all losses, claims, damages, liabilities
(including amounts paid in settlement with the written consent of USAA Life) or
actions in respect thereof (including, to the extent reasonable, legal and other
expenses), to which the Indemnified Parties may become subject under any
statute, regulation, at common law or otherwise, insofar as such losses, claims,
damages, liabilities or actions are related to the sale or acquisition of the
Trust's shares and:

     (i) arise out of or are based upon any untrue statement or alleged untrue
         statement of any material fact contained in the Separate Account's or
         the Life Insurance Separate Account's 1933 Act registration statement,
         the Separate Account Prospectus, the Life Insurance Separate Account
         Prospectus, the Contracts, the Policies or sales literature or
         advertising for the Contracts or the Policies (or any amendment or
         supplement to any of the foregoing), or arise out of or are based upon
         the omission or the alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading; provided that this agreement to indemnify shall
         not apply as to any Indemnified Party if such statement or omission or
         such alleged statement or omission was made in reliance upon and in
         conformity with information furnished to USAA Life or its affiliates by
         or on behalf of the Trust, Distributor or Adviser for use in the
         Separate Account's or the Life Insurance Separate Account's 1933 Act
         registration statement, the Separate Account Prospectus, the Life
         Insurance Separate Account Prospectus, the Contracts, the Policies, or
         sales literature or advertising (or any amendment or supplement to any
         of the foregoing); or

    (ii) arise out of or as a result of any other statements or representations
         (other than statements or representations contained in the Trust's 1933

            supplied for use therein by or on behalf of USAA Life or its
            affiliates) or the negligent, illegal or fraudulent conduct of USAA
            Life or its affiliates or persons under their control (including,
            without limitation, their employees and "Associated Persons," as
            that term is defined in paragraph (m) of Article I of the NASD's By-
            Laws), in connection with the sale or distribution of the Contracts;
            or

     (iii)  arise out of or are based upon any untrue statement or alleged
            untrue statement of any material fact contained in the Trust's 1933
            Act registration statement, Trust Prospectus, sales literature or
            advertising of the Trust, or any amendment or supplement to any of
            the foregoing, or the omission or alleged omission to state therein
            a material fact required to be stated therein or necessary to make
            the statements therein not misleading if such a statement or
            omission was made in reliance upon and in conformity with
            information furnished to the Trust, Adviser or Distributor by or on
            behalf of USAA Life or its affiliates for use in the Trust's 1933
            Act registration statement, Trust Prospectus, sales literature or
            advertising of the Trust, or any amendment or supplement to any of
            the foregoing; or

     (iv)   arise as a result of any failure by USAA Life to perform the
            obligations, provide the services and furnish the materials required
            of them under the terms of this Agreement, or any material breach of
            any representation and/or warranty made by USAA Life in this
            Agreement or arise out of or result from any other material breach
            of this Agreement by USAA Life; or

     (v)    arise as a result of failure by the Contracts or Policies issued by
            USAA Life to qualify as annuity contracts or life insurance
            policies, respectively, under the Code, otherwise than by reason of
            any Portfolio's failure to comply with Subchapter M or Section
            817(h) of the Code.

     (b)    USAA Life shall not be liable under this Section 12.1 with respect
to any losses, claims, damages, liabilities or actions to which an Indemnified
Party would otherwise be subject by reason of willful misfeasance, bad faith, or
gross negligence in the performance by that Indemnified Party of its duties or
by reason of that Indemnified Party's reckless disregard of obligations or
duties (i) under this Agreement or (ii) to Distributor or to the Trust.

     (c)    USAA Life shall not be liable under this Section 12.1 with respect
to any action against an Indemnified Party unless the Trust, Distributor or
Adviser shall have notified USAA Life in writing within a reasonable time after
the summons or other first legal process giving information of the nature of the
action shall have been served upon such Indemnified Party (or after such
Indemnified Party shall have received notice of such service on any designated
agent), but failure to notify USAA Life of any such action shall not relieve
USAA Life from any liability which it may have to the Indemnified Party against
whom such action is brought otherwise than on account of

                                      21
<PAGE>
 
this Section 12.1. In case any such action is brought against an Indemnified
Party, USAA Life shall be entitled to participate, at its own expense, in the
defense of such action. USAA Life also shall be entitled to assume the defense
thereof, with counsel approved by the Indemnified Party named in the action,
which approval shall not be unreasonably withheld. After notice from USAA Life
to such Indemnified Party of USAA Life's election to assume the defense thereof,
the Indemnified Party will cooperate fully with USAA Life and shall bear the
fees and expenses of any additional counsel retained by it, and USAA Life will
not be liable to such Indemnified Party under this Agreement for any legal or
other expenses subsequently incurred by such Indemnified Party independently in
connection with the defense thereof, other than reasonable costs of
investigation.


     12.2 Of USAA Life by Distributor and Adviser.

     (a) Except to the extent provided in Sections 12.2(d) and 12.2(e), below,
Distributor and Adviser agree to indemnify and hold harmless USAA Life and its
affiliates, each of their directors and officers, and each person, if any, who
controls USAA Life or its affiliates within the meaning of Section 15 of the
1933 Act (collectively, the "Indemnified Parties" for purposes of this Section
12.2) against any and all losses, claims, damages, liabilities (including
amounts paid in settlement with the written consent of Distributor and/or
Adviser) or actions in respect thereof (including, to the extent reasonable,
legal and other expenses) to which the Indemnified Parties may become subject
under any statute, at common law or otherwise, insofar as such losses, claims,
damages, liabilities or actions are related to the sale or acquisition of the
Trust's shares and:

    (i) arise out of or are based upon any untrue statement or alleged untrue
        statement of any material fact contained in the Trust's 1933 Act
        registration statement, Trust Prospectus or sales literature or
        advertising of the Trust (or any amendment or supplement to any of the
        foregoing), or arise out of or are based upon the omission or the
        alleged omission to state therein a material fact required to be stated
        therein or necessary to make the statements therein not misleading;
        provided that this agreement to indemnify shall not apply as to any
        Indemnified Party if such statement or omission or such alleged
        statement or omission was made in reliance upon and in conformity with
        information furnished to the Trust Distributor or Adviser by or on
        behalf of USAA Life or its affiliates for use in the Trust's 1933 Act
        registration statement, Trust Prospectus, or in sales literature or
        advertising (or any amendment or supplement to any of the foregoing); or

   (ii) arise out of or as a result of any other statements or representations
        (other than statements or representations contained in the Separate
        Account's or Life Insurance Separate Account's 1933 Act registration
        statement, Separate Account Prospectus, Life Insurance Separate Account
        Prospectus, sales literature or advertising for the Contracts or
        Policies, or any amendment or supplement to any of the foregoing, not
        supplied for use therein by or on behalf of the Trust, Distributor or
        Adviser) or the negligent, illegal or fraudulent conduct of the Trust,
        Distributor, Adviser or persons

        under their control (including, without limitation, their employees and
        Associated Persons), in connection with the sale or distribution of
        Trust shares; or

  (iii) arise out of or are based upon any untrue statement or alleged
        untrue statement of any material fact contained in the Separate
        Account's or Life Insurance Separate Account's 1933 Act registration
        statement, Separate Account Prospectus, Life Insurance Separate Account
        Prospectus, sales literature or advertising covering the Contracts or
        Policies, or any amendment or supplement to any of the foregoing, or the
        omission or alleged omission to state therein a material fact required
        to be stated therein or necessary to make the statements therein not
        misleading, if such statement or omission was made in reliance upon and
        in conformity with information furnished to USAA Life or its affiliates
        by or on behalf of the Trust, Distributor or Adviser for use in the
        Separate Account's or Life Insurance Separate Account's 1933 Act
        registration statement, Separate Account Prospectus, Life Insurance
        Separate Account Prospectus, sales literature or advertising covering
        the Contracts or Policies, or any amendment or supplement to any of the
        foregoing; or

   (iv) arise as a result of any failure by the Trust, Distributor or Adviser to
        perform the obligations, provide the services and furnish the materials
        required of them under the terms of this Agreement, or any material
        breach of any representation and/or warranty made by the Trust,
        Distributor, or Adviser in this Agreement or arise out of or result from
        any other material breach of this Agreement by the Trust, Distributor,
        or Adviser.

     (b) Except to the extent provided in Sections 12.2(d) and 12.2(e) hereof,
Distributor and Adviser agree to indemnify and hold harmless the Indemnified
Parties from and against any and all losses, claims, damages, liabilities
(including amounts paid in settlement thereof with, except as set forth in
Section 12.2(c) below, the written consent of Distributor and/or Adviser) or
actions in respect thereof (including, to the extent reasonable, legal and other
expenses) to which the Indemnified Parties may become subject directly or
indirectly under any statute, at common law or otherwise, insofar as such
losses, claims, damages, liabilities or actions directly or indirectly result
from or arise out of the failure of any Portfolio to operate as a regulated
investment company in compliance with (i) Subchapter M of the Code and
regulations thereunder or (ii) Section 817(h) of the Code and regulations
thereunder, including, without limitation, any income taxes and related
penalties, rescission charges, liability under state law to Contract owners,
Policy owners or Participants asserting liability against USAA Life or its
affiliates pursuant to the Contracts or Policies, the costs of any ruling and
closing agreement or other settlement with the Internal Revenue Service, and the
cost of any substitution by USAA Life of shares of another investment company or
portfolio for those of any adversely affected Portfolio as a funding medium for
the Separate Account or Life Insurance Separate Account that USAA Life
reasonably deems necessary or appropriate as a result of the noncompliance.

                                      23
<PAGE>
 
     (c) The written consent of Distributor and/or Adviser referred to in
Section 12.2(b) above shall not be required with respect to amounts paid in
connection with any ruling and closing agreement or other settlement with the
Internal Revenue Service.

     (d) Distributor and Adviser shall not be liable under this Section 12.2
with respect to any losses, claims, damages, liabilities or actions to which an
Indemnified Party would otherwise be subject by reason of willful misfeasance,
bad faith, or gross negligence in the performance by that Indemnified Party of
its duties or by reason of such Indemnified Party's reckless disregard of its
obligations and duties (i) under this Agreement or (ii) to USAA Life, the
Separate Account, the Life Insurance Separate Account or Participants.

     (e) Distributor and Adviser shall not be liable under this Section 12.2
with respect to any action against an Indemnified Party unless USAA Life or its
affiliates shall have notified Distributor and/or Adviser in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the action shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify Distributor and/or
Adviser of any such action shall not relieve Distributor or Adviser from any
liability which it may have to the Indemnified Party against whom such action is
brought otherwise than on account of this Section 12.2.  In case any such action
is brought against an Indemnified Party, Distributor and/or Adviser will be
entitled to participate, at its own expense, in the defense of such action.
Distributor and/or Adviser also shall be entitled to assume the defense thereof
(which shall include, without limitation, the conduct of any ruling request and
closing agreement or other settlement proceeding with the Internal Revenue
Service), with counsel approved by the Indemnified Party named in the action,
which approval shall not be unreasonably withheld.  After notice from
Distributor or Adviser to such Indemnified Party of Distributor or Adviser's
election to assume the defense thereof, the Indemnified Party will cooperate
fully with Distributor or Adviser and shall bear the fees and expenses of any
additional counsel retained by it, and Distributor or Adviser will not be liable
to such Indemnified Party under this Agreement for any legal or other expenses
subsequently incurred by such Indemnified Party independently in connection with
the defense thereof, other than reasonable costs of investigation.


     12.3 Effect of Notice.

     Any notice given by the indemnifying Party to an Indemnified Party referred
to in Section 12.1(c) or 12.2(e) above of participation in or control of any
action by the indemnifying Party will in no event be deemed to be an admission
by the indemnifying Party of liability, culpability or responsibility, and the
indemnifying Party will remain free to contest liability with respect to the
claim among the Parties or otherwise.

                      FORM OF FUND PARTICIPATION AGREEMENT
                                        
     THIS AGREEMENT ("Agreement") made as of the ___ day of ________, 1998, by
and among BT Insurance Funds Trust ("TRUST"), a Massachusetts business trust,
Bankers Trust Company ("ADVISER"), a New York banking corporation, and USAA Life
Insurance Company ("LIFE COMPANY"), a life insurance company organized under the
laws of the State of Texas (collectively, the "Parties").

     WHEREAS, TRUST is registered with the Securities and Exchange Commission
("SEC") under the Investment Company Act of 1940, as amended (the "'40 Act"), as
an open-end diversified management investment company; and

     WHEREAS, TRUST is comprised of several series funds (each a "Series"), each
of whose shares are registered under the Securities Act of 1933, as amended ("
'33 Act"); and

     WHEREAS, TRUST was organized to act as the funding vehicle for certain
variable life insurance and/or variable annuity contracts ("Variable Contracts")
offered by life insurance companies ("Participating Insurance Companies")
through their separate accounts; and

     WHEREAS, TRUST may also offer its shares to certain qualified pension and
retirement plans ("Qualified Plans"); and

     WHEREAS, TRUST has received an order from the SEC granting Participating
Insurance Companies and their separate accounts exemptions from the provisions
of Sections 9(a), 13(a), 15(a) and 15(b) of the '40 Act, and Rules 6e-2(b)(15)
and 6e-3(T)(b)(1-5) thereunder, to the extent necessary to permit shares of the
Series of the TRUST to be sold to and held by  separate accounts of both
affiliated and unaffiliated Participating Insurance Companies and Qualified
Plans ("Exemptive Order"); and

     WHEREAS, LIFE COMPANY has established or will establish one or more
separate accounts listed on Appendix A hereto (collectively, "Separate
Accounts") to offer certain Variable Contracts issued by LIFE COMPANY and funded
by the Separate Accounts listed on Appendix A hereto (collectively, "Contracts")
and is desirous of having the Series listed on Appendix B hereto (each, a
"Portfolio") serve as underlying funding vehicles for the Contracts; and

     WHEREAS, ADVISER is a "bank" as defined in the Investment Advisers Act of
1940, as amended (the "Advisers Act") and as such is excluded from the
definition of "Investment Adviser" and is not required to register as an
investment adviser pursuant to the Advisers Act; and
 

                                       1
<PAGE>
 
     WHEREAS, ADVISER serves as the TRUST's investment adviser; and

     WHEREAS, First Data Distributors, Inc., a corporation organized under the
     law of  ____("DISTRIBUTOR") serves as the Trust's principal underwriter of
     the Trust's shares; and

     WHEREAS, to the extent permitted by applicable insurance laws and
regulations, LIFE COMPANY intends to purchase shares of Portfolios to fund the
Contracts and TRUST is authorized to sell such shares to LIFE COMPANY at such
shares' net asset value;

     NOW, THEREFORE, in consideration of their mutual promises, LIFE COMPANY,
TRUST, and ADVISER agree as follows:


                        Article I. SALE OF TRUST SHARES
                                   --------------------

  1.1     TRUST agrees to make available to the Separate Accounts shares of each
Portfolio ("Shares") for purchase and redemption at net asset value, and with no
sales charges, subject to the terms and conditions of this Agreement.  The
Parties may agree, from time to time, to amend Appendicies A and/or B hereto
("Appendix A" and "Appendix B," respectively) to reflect additions, deletions,
and other changes to the Separate Accounts, Contracts, and/or Portfolios.  Upon
such amendment, references to Separate Account, Contract, Portfolio, Trust or
Shares shall be read consistently with the changes effected by that amendment,
unless otherwise specifically provided.

  1.2     TRUST agrees to execute orders to purchase Shares ("Purchase orders")
that correspond to Contract owner transaction requests received by LIFE COMPANY
("requests" or "Contract owner requests") on each Business Day using the net
asset value per Share next computed after the LIFE COMPANY receives the
requests. The Parties agree that, unless otherwise specified in writing by
TRUST, the computation of each Portfolio's net asset value per Share will occur
as of 4:00 p.m. New York time each Business Day. For purposes of this Agreement,
"Business Day" shall mean any day on which the New York Stock Exchange is open
for trading and on which TRUST calculates its net asset value pursuant to the
rules of the SEC.

  1.3     TRUST agrees to execute orders to redeem Shares ("Redemption orders")
that correspond to Contract owner requests on each Business Day using the net
asset value per Share next computed after the LIFE COMPANY receives the
requests.  Redemption orders that do not relate to requests will be executed
using the net asset value per Share next computed after receipt by TRUST of such
orders.

  1.4     TRUST shall furnish, on or before each ex-dividend date, notice to
LIFE COMPANY of any income dividends or capital gain distributions payable on
the Shares of any Portfolio. LIFE COMPANY hereby elects to receive all such
income dividends and capital gain distributions as are payable on a Portfolio's
Shares in additional Shares of the Portfolio. TRUST shall notify LIFE COMPANY or
its designee of the number of Shares so issued as payment of such dividends and
distributions.

                                       2
<PAGE>
 
  1.5     TRUST shall make the net asset value per Share for the Portfolios
available to LIFE COMPANY on a daily basis as soon as reasonably practicable
after the net asset value per Share is calculated but shall use its best efforts
to make such net asset value available by 6:30 p.m. New York time. If TRUST
provides LIFE COMPANY with materially incorrect Share net asset value
information through no fault of LIFE COMPANY, LIFE COMPANY on behalf of the
Separate Accounts, shall be entitled to an adjustment to the number of Shares
purchased or redeemed to reflect the correct Share net asset value. Any material
error in the calculation of net asset value per Share, dividend or capital gain
information shall be reported promptly by TRUST upon discovery to LIFE COMPANY.

  1.6     LIFE COMPANY shall be the designee of TRUST for receipt of Purchase
orders and Redemption orders from the designated Separate Account to purchase or
redeem Shares that correspond to Contract owner transactions.  At the end of
each Business Day, LIFE COMPANY shall use the information described in Section
1.5 to calculate Separate Account unit values for that Day. Using these unit
values, LIFE COMPANY shall process each such Business Day's Contract owner
transactions based on requests received by the close of trading on the floor of
the New York Stock Exchange (currently 4:00 P.M. New York time) to determine the
net dollar amount of Shares which shall be purchased or redeemed at that Day's
closing net asset value per   Share.  LIFE COMPANY shall net all Purchase and
Redemption orders, and shall submit a net order ("Net Order") to TRUST by 10:00
a.m. New York time on the Business Day next following LIFE COMPANY's receipt of
such requests in accordance with the terms of Sections 1.2 and 1.3 hereof;
provided, however, that TRUST shall provide additional time to LIFE COMPANY in
the event that TRUST is unable to meet the 6:30 p.m. time stated in Section 1.5
hereof.  Such additional time shall be equal to the additional time that TRUST
takes to make the net asset values available to LIFE COMPANY.

  1.7     If  LIFE COMPANY's Net Order  requests the purchase of TRUST Shares,
LIFE COMPANY shall pay for such purchase by wiring federal funds to TRUST or its
designated custodial account on the day the order is transmitted by LIFE
COMPANY.  If LIFE COMPANY's  Net Order requests a net redemption resulting in a
payment of redemption proceeds to LIFE COMPANY, TRUST shall  wire the redemption
proceeds to LIFE COMPANY by the next Business Day, unless doing so would require
TRUST to dispose of Portfolio securities or otherwise incur additional costs. In
any event, proceeds shall be wired to LIFE COMPANY within the time period
permitted by the '40 Act or the rules, orders or regulations thereunder, and
TRUST shall notify the person designated in writing by LIFE COMPANY as the
recipient for such notice of such delay by 3:00 p.m. New York time on the same
Business Day that LIFE COMPANY transmits the Net Redemption Order to TRUST. If
LIFE COMPANY's Net Order requests the application of redemption proceeds from
the redemption of Shares to the purchase of shares of another fund advised by
ADVISER, TRUST shall so apply such proceeds on the same Business Day that LIFE
COMPANY transmits such order to TRUST.

  1.8     TRUST agrees that all Shares of the Portfolios will be sold only to
Participating Insurance Companies which have agreed to participate in TRUST to
fund their separate accounts and/or to Qualified Plans, all in accordance with
the requirements of Section 817(h)(4) of the

                                       3
<PAGE>
 
Internal Revenue Code of 1986, as amended ("Code") and Treasury Regulation
1.817-5. Shares of the TRUST's Series will not be sold directly to the general
public.

  1.9     TRUST may refuse to sell Shares of any Portfolio to any person, or
suspend or terminate the offering of the Shares of or liquidate any Portfolio of
TRUST if such action is required by law or by regulatory authorities having
jurisdiction or is, in the sole discretion of the Board of Trustees of the TRUST
(the "Board"), acting in good faith and in light of its duties under federal and
any applicable state laws, deemed necessary, desirable or appropriate and in the
best interests of the Shareholders of such Portfolios.

  1.10    Issuance and transfer of  Shares will be by book entry only. Stock
certificates will not be issued to LIFE COMPANY or the Separate Accounts. The
TRUST will record, or cause to be recorded, Shares ordered from any Portfolio in
appropriate book entry titles for the Separate Accounts.

                   Article II. REPRESENTATIONS AND WARRANTIES
                               ------------------------------

registered to serve as a segregated asset account for the  Contracts, unless an
exemption from registration is available.

connection with the Contracts have been or will be registered under the '33 Act

applicable state insurance law suitability requirements.

ceased to be so treated or that they might not be so treated in the future.

TRUST.

will immediately take all reasonable steps to adequately diversify the Portfolio
to achieve compliance.

  2.7     TRUST  and ADVISER represent and warrant that each Portfolio invested
in by the Separate Account will be treated as a "regulated investment company"
under Subchapter M of the Code, and will notify LIFE COMPANY immediately upon
having a reasonable basis for believing it has ceased to so qualify or might not
so qualify in the future.

  2.8     ADVISER represents and warrants that it shall perform its obligations
hereunder in compliance in all material respects with any applicable state and
federal laws.

               Article III. PROSPECTUS AND OTHER TRUST DOCUMENTS

  3.1     TRUST shall prepare and be responsible for filing with the SEC and any
state regulators requiring such filing all Shareholder reports, notices, proxy
materials (or similar materials such as voting instruction solicitation
materials), prospectuses and statements of additional information of TRUST.
TRUST shall bear the costs of registration and qualification of shares of the
Portfolios, preparation and filing of the documents listed in this Section 3.1

as many copies of the current prospectus (or prospectuses), including
supplements, statements of additional information, annual and semi-annual
reports and proxy materials  for the Shares of the Portfolios as LIFE COMPANY
may reasonably request for distribution to existing Contract owners whose
Contracts are funded by Shares. TRUST or its designee shall provide LIFE
COMPANY, at LIFE COMPANY's expense, with as many copies of the current
prospectus (or prospectuses) for the Shares ("TRUST prospectus") as LIFE COMPANY
may reasonably request for distribution to prospective purchasers of Contracts.

prospectus is supplemented or amended) to have the prospectus for the Contracts

document. The expenses of such printing will be apportioned between LIFE COMPANY

for providing the TRUST prospectus in the format in which it is accustomed to
formatting prospectuses and shall bear the expense of providing the TRUST

prospectuses.

or representations contained in a registration statement or TRUST prospectus, or
prospectus for any Portfolio, as such registration statement or prospectus may
be amended or supplemented from time to time, or in sales literature approved by
TRUST or its designee, except with the written permission of TRUST.

  4.5     For purposes of this Agreement, the phrase "sales literature"
includes, without limitation, advertisements (such as material published, or
designed for use, in a newspaper, magazine or other periodical, radio,
television, telephone or tape recording, videotape display, signs or billboards,
motion pictures or other public media), sales literature (such as any written
communication distributed or made generally available to customers or the
public, including brochures, circulars, research reports, market letters, form
letters, seminar texts, or reprints or excerpts of any other advertisement,
sales literature, or published article), educational or training materials or
other communications distributed or made generally available to some or all
agents or employees,  prospectuses, statements of additional information,
shareholder reports and proxy materials, and any other material constituting
sales literature or advertising under National Association of Securities
Dealers, Inc. ("NASD") rules, the '40 Act, the '33 Act, or rules thereunder.

                         Article V. POTENTIAL CONFLICTS
                                    -------------------
                                        
  5.1     The TRUST  represents that it has received The Exemption Order from
the SEC granting relief from various provisions of the '40 Act and the rules
thereunder to the extent necessary to permit TRUST Shares to be sold to and held
by  separate accounts of both affiliated and unaffiliated Participating
Insurance Companies and Qualified Plans. The Exemptive Order requires TRUST and
each Participating Insurance Company to comply with conditions and undertakings
substantially as provided in this Section 5.  The TRUST agrees not to  enter
into a participation agreement with any other Participating Insurance Company
unless it imposes the same conditions and undertakings as are imposed on LIFE
COMPANY hereby.

  5.2     The Board will monitor TRUST for the existence of any material
irreconcilable conflict between the  Variable Contract owners of all separate
accounts, including the Contract owners investing in the Separate Accounts, and
of participants of Qualified Plans investing in TRUST, and determine what
action, if any, should be taken in response to such conflicts.   An
irreconcilable material conflict may arise for a variety of reasons, which may
include: (a) an action by any state insurance regulatory authority; (b) a change
in applicable federal or state insurance, tax, or securities laws or
regulations, or a public ruling, private letter ruling, no-action or
interpretive letter, or any similar action by insurance, tax or securities
regulatory authorities; (c) an administrative or judicial decision in any
relevant proceeding; (d) the manner in which the investments of TRUST are being
managed; (e) a difference in voting instructions given by Variable Contract
owners; or (f) a decision by a Participating Insurance Company to disregard the
voting instructions of Variable Contract owners.

  5.3     LIFE COMPANY will report any potential or existing conflicts of which
it becomes aware to the Board. LIFE COMPANY will be responsible for assisting
the Board in carrying out its responsibilities in this regard by providing the
Board with all information reasonably necessary for the Board to consider any
issues raised. This responsibility includes,

                                       7
<PAGE>
 
but is not limited to, an obligation by the LIFE COMPANY to inform the Board
whenever it has determined to disregard Contract owners' voting instructions.
These responsibilities of LIFE COMPANY will be carried out with a view only to
the interests of the Contract owners.

  5.4     If a majority of the Board, or majority of its disinterested Trustees,
determines that a material irreconcilable conflict exists affecting LIFE
COMPANY, LIFE COMPANY, at its expense and to the extent reasonably practicable
(as determined by a majority of the Board's disinterested Trustees), will take
any steps necessary to remedy or eliminate the material irreconcilable conflict,
including; (a) withdrawing the assets allocable to some or all of the Separate
Accounts from TRUST or any Portfolio thereof and reinvesting those assets in a
different investment medium, which may include another portfolio of TRUST ; (b)
submitting the question as to whether such segregation should be implemented to
a vote of all affected  Contract owners and as appropriate, segregating the
assets of any appropriate group of Contract owners that votes in favor of such
segregation, or offering to the affected  Contract owners the option of making
such a change; and (c) establishing a new registered management investment
company (or series thereof) or managed separate account. If a material
irreconcilable conflict arises because of LIFE COMPANY's decision to disregard
Contract owner voting instructions, and that decision represents a minority
position or would preclude a majority vote, LIFE COMPANY may be required, at the
election of TRUST, to withdraw a Separate Account's investment in TRUST, and no
charge or penalty will be imposed as a result of such withdrawal. The
responsibility to take such remedial action shall be carried out with a view
only to the interests of the Contract owners.

  For the purposes of this Section 5.4, a majority of the disinterested Trustees
shall determine whether or not any proposed action adequately remedies any
material irreconcilable conflict, but in no event will TRUST or ADVISER (or any
other investment adviser of TRUST) be required to establish a new funding medium
for any Contract. Further, LIFE COMPANY shall not be required by this Section
5.4 to establish a new funding medium for any Contracts if an offer to do so has
been declined by a vote of a majority of Contract owners materially and
adversely affected by the material irreconcilable conflict.

  5.5     The Board's determination of the existence of an irreconcilable
material conflict and its implications shall be made known promptly and in
writing to LIFE COMPANY.

  5.6     No less than annually, LIFE COMPANY shall submit to the Board such
reports, materials or data as the Board may reasonably request so that the Board
may fully carry out its obligations. Such reports, materials, and data shall be
submitted more frequently if deemed appropriate by the Board.

                               Article VI. VOTING
                                           ------
                                        
  6.1     LIFE COMPANY will provide pass-through voting privileges to all
Contract owners so long as the SEC continues to interpret the '40 Act as
requiring pass-through voting privileges for Contract owners. Accordingly, LIFE
COMPANY, where applicable, will vote Shares of any Portfolio held in its
Separate Account(s) in a manner consistent with voting instructions timely
received from its Contract owners. LIFE COMPANY will be responsible for

                                       8
<PAGE>
 
assuring that each of its registered Separate Account(s) that owns any Shares
calculates voting privileges in a manner consistent with other Participating
Insurance Companies. LIFE COMPANY will vote Shares that are not attributable to
Contract owners to whom pass-through voting privileges are extended, or that are
attributable to Contract owners from whom timely voting instructions were not
received, in the same proportion as it votes those Shares for which it has
received voting instructions. Notwithstanding the foregoing, LIFE COMPANY
reserves the right to vote Shares held in any Separate Account in its own right,
to the extent permitted by law. TRUST will promptly notify LIFE COMPANY of any
amendment to, or change in interpretation of, the Exemptive Order it has
obtained.

  6.2     If and to the extent Rule 6e-2 and Rule 6e-3(T) are amended, or if
Rule 6e-3 is adopted, to provide exemptive relief from any provision of the '40
Act or the rules thereunder with respect to mixed and shared funding on terms
and conditions materially different from any exemptions granted in the Exemptive
Order, then TRUST, and/or LIFE COMPANY, as appropriate, shall take such steps as
may be necessary to comply with Rule 6e-2 and Rule 6e-3(T), as amended, and Rule
6e-3, as adopted, to the extent such Rules are applicable.

                          Article VII. INDEMNIFICATION
                                       ---------------
                                        
  7.1     Indemnification by LIFE COMPANY. LIFE COMPANY agrees to indemnify and
hold harmless TRUST, and ADVISER and each of their respective trustees,
directors, principals, officers, employees and agents (and former trustees,
directors, principals, officers, employees, and agents) and each person, if any,
who controls TRUST or ADVISER within the meaning of Section 15 of the '33 Act
(collectively, the "Indemnified Parties") against any and all losses, claims,
damages, liabilities (including amounts paid in settlement with the written
consent of LIFE COMPANY, which consent shall not be unreasonably withheld) or
litigation or threatened litigation (including reasonable legal and other
expenses), to which the Indemnified Parties may become subject under any statute
or regulation, at common law or otherwise, insofar as such losses, claims,
damages, liabilities or expenses (or actions in respect thereof) or settlements
are related to the sale or acquisition of Shares or the Contracts and:

  (a)     arise out of or are based upon any untrue statements or alleged untrue
          statements of any material fact contained in the Contracts, any
          Separate Account's registration statement or Contract prospectus
          contained therein, or in any sales literature for the Contracts (or
          any amendment or supplement to any of the foregoing), or arise out of
          or are based upon the omission or the alleged omission to state
          therein a material fact required to be stated therein or necessary to
          make the statements therein not misleading, provided that this
          agreement to indemnify shall not apply as to any Indemnified Party if
          such statement or omission or such alleged statement or omission was
          made in reliance upon and in conformity with information furnished in
          writing to LIFE COMPANY by or on behalf of TRUST, ADVISER or
          DISTRIBUTOR for use in the Contracts, any Separate Account's
          registration statement or Contract prospectus or sales literature for
          the Contracts (or any amendment or supplement supplement to any of the
          foregoing) or otherwise for use in connection with the sale of the
          Contracts or  Shares; or

                                       9
<PAGE>
 
  (b)     arise out of or result from (i) statements or representations
          (other than statements or representations contained in  any
          registration statement, prospectus or sales literature for the TRUST,
          or any Portfolio not supplied by LIFE COMPANY, or persons under its
          control) or (ii) willful misfeasance, bad faith, negligence, or
          reckless disregard of obligations or duties of LIFE COMPANY or persons
          under its control, with respect to the sale or distribution of the
          Contracts or Shares; or (c) arise out of any untrue statement or
          alleged untrue statement of a material fact contained in  any
          registration statement, prospectus, or sales literature  for the
          TRUST, or any Portfolio, or any amendment or supplement to any of the
          foregoing, or the omission or alleged omission to state therein a
          material fact required to be stated therein or necessary to make the
          statements therein not misleading, if such statement or omission or
          such alleged statement or omission was made in reliance upon and in
          conformity with information furnished in writing to TRUST by or on
          behalf of LIFE COMPANY for use in such materials; or
 
  (d)     arise as a result of any failure by LIFE COMPANY to provide
          substantially the services and furnish the materials under the terms
          of this Agreement; or

  (e)     arise out of or result from any material breach of any
          representation and/or warranty made by LIFE COMPANY in this Agreement
          or arise out of or result from any other material breach of this
          Agreement by LIFE COMPANY.

  7.2     LIFE COMPANY shall not be liable under Section 7.1 hereof with respect
to any losses, claims, damages, liabilities or litigation incurred or assessed
against an Indemnified Party to the extent that such losses, claims, damages,
liabilities or litigation are attributable to such Indemnified Party's willful
misfeasance, bad faith, negligence in the performance of such Indemnified
Party's duties or by reason of such Indemnified Party's reckless disregard of
obligations or duties under this Agreement or breach of this Agreement.

  7.3     LIFE COMPANY shall not be liable under this indemnification provision
with respect to any claim made against an Indemnified Party unless such
Indemnified Party shall have notified LIFE COMPANY in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify LIFE COMPANY of any
such claim shall not relieve LIFE COMPANY from any liability which it may have
to the Indemnified Party against whom such action is brought otherwise than on
account of this indemnification provision. In case any such action is brought
against an Indemnified Party, LIFE COMPANY shall be entitled to participate at
its own expense in the defense of such action. LIFE COMPANY also shall be
entitled to assume the defense thereof, with counsel satisfactory to the
Indemnified Party named in the action. After notice from LIFE COMPANY to such
Indemnified Party of LIFE COMPANY's election to assume the defense thereof, the
Indemnified Party shall bear the fees and expenses of any additional counsel
retained by it, and LIFE COMPANY will not be liable to such Indemnified Party
under this Agreement for any legal or other expenses subsequently

                                       10
<PAGE>
 
incurred by such Indemnified Party independently in connection with the defense
thereof other than reasonable costs of investigation.

  7.4     Indemnification by TRUST and ADVISER.  TRUST and ADVISER agree to
indemnify and hold harmless LIFE COMPANY and each of its directors, principals,
officers, employees, and agents (and former directors, principals, officers,
employees, and agents) and each person, if any, who controls LIFE COMPANY within
the meaning of Section 15 of the '33 Act (collectively, the "Indemnified
Parties") against any and all losses, claims, damages, liabilities (including
amounts paid in settlement with the written consent of TRUST and ADVISER which
consent shall not be unreasonably withheld) or litigation or threatened
litigation (including reasonable legal and other expenses) to which the
Indemnified Parties may become subject under any statute, or regulation, at
common law or otherwise, insofar as such losses, claims, damages, liabilities or
expenses (or actions in respect thereof) or settlements are related to the sale
or acquisition of  Shares or the Contracts and:

  (a)     arise out of or are based upon any untrue statement or alleged
          untrue statement of any material fact contained in  any registration
          statement or prospectus or sales literature for the TRUST or any
          Portfolios (or any amendment or supplement to any of the foregoing),
          or arise out of or are based upon the omission or the alleged omission
          to state therein a material fact required to be stated therein or
          necessary to make the statements therein not misleading, provided that
          this agreement to indemnify shall not apply as to any Indemnified
          Party if such statement or omission or such alleged statement or
          omission was made in reliance upon and in conformity with information
          furnished in writing to TRUST, ADVISER, or DISTRIBUTOR by or on behalf
          of LIFE COMPANY for use in   any registration statement,  prospectus
          or  sales literature for the TRUST or any Portfolio (or any amendment
          or supplement to any of the foregoing) or otherwise for use in
          connection with the sale of the Contracts or  Shares; or

  (b)     arise out of or result from (i) statements or representations (other
          than statements or representations contained in any Separate Account's
          registration statement or Contract prospectus, or sales literature for
          the Contracts not supplied by TRUST, ADVISER or DISTRIBUTOR or persons
          under their respective control) or (ii) willful misfeasance or bad
          faith, negligence, or reckless disregard of obligations or duties of
          ADVISER, TRUST or DISTRIBUTOR or persons under their respective
          control, with respect to the sale or distribution of the Contracts or
          Shares; or

  (c)     arise out of any untrue statement or alleged untrue statement of a
          material fact contained in any Separate Account's registration
          statement or Contract prospectus, or sales literature for the
          Contracts, or any amendment or supplement to any of the foregoing or
          the omission or alleged omission to state therein a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, if such statement or omission or such alleged
          statement or omission was made in reliance upon and in conformity with

                                       11
<PAGE>
 
          information furnished in writing to LIFE COMPANY for inclusion therein
          by or on behalf of TRUST, ADVISER or DISTRIBUTOR; or

  (d)     arise as a result of (i) a failure by TRUST, or ADVISER   to provide
          substantially the services and furnish the materials under the terms
          of this Agreement;  (ii) a failure by a Portfolio(s) to comply with
          the diversification requirements of Section 817(h) of the Code; or
          (iii) a failure by a Portfolio(s)  to qualify as a "regulated
          investment company" under Subchapter M of the Code; or

  (e)     arise out of or result from any material breach of any representation
          and/or warranty made by TRUST, or ADVISER  in this Agreement or arise
          out of or result from any other material breach of this Agreement by
          TRUST, or ADVISER.
 
  7.5     TRUST and ADVISER shall not be liable under Section 7.4 hereof with
respect to any losses, claims, damages, liabilities or litigation incurred or
assessed against an Indemnified Party to the extent that such losses, claims,
damages, liabilities or litigation are attributable to such Indemnified Party's
willful misfeasance, bad faith, or  negligence in the performance of such
Indemnified Party's duties or by reason of such Indemnified Party's reckless
disregard of obligations and duties under this Agreement or breach of this
Agreement.
 
  7.6     TRUST and ADVISER shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified TRUST and ADVISER in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify TRUST and ADVISER
of any such claim shall not relieve TRUST and ADVISER from any liability which
it may have to the Indemnified Party against whom such action is brought
otherwise than on account of this indemnification provision. In case any such
action is brought against an Indemnified Party, TRUST and ADVISER shall be
entitled to participate at its own expense in the defense of such action. TRUST
and ADVISER also shall be entitled to assume the defense thereof, with counsel
satisfactory to the Indemnified Party named in the action. After notice from
TRUST and ADVISER to such Indemnified Party of TRUST and ADVISER's election to
assume the defense thereof, the Indemnified Party shall bear the fees and
expenses of any additional counsel retained by it, and TRUST and ADVISER will
not be liable to such Indemnified Party under this Agreement for any legal or
other expenses subsequently incurred by such Indemnified Party independently in
connection with the defense thereof other than reasonable costs of
investigation.
 
                        Article VIII. TERM: TERMINATION
                                      -----------------

          hereof upon 180 days' notice, unless a shorter time is agreed to in
          writing by the Parties;

  (b)     At the option of LIFE COMPANY, if TRUST Shares are not reasonably
          available to meet the requirements of the Contracts as determined by
          LIFE COMPANY. Prompt notice of election to terminate shall be
          furnished by LIFE COMPANY, said termination to be effective ten days
          after receipt of notice unless TRUST makes available a sufficient

          within said ten-day period;
 
  (c)     At the option of LIFE COMPANY, upon the institution of formal
          proceedings against TRUST or ADVISER by the SEC, the NASD, or any
          other regulatory body, the expected or anticipated ruling, judgment or
          outcome of which would, in LIFE COMPANY's reasonable judgment,
          materially impair the ability of the TRUST, or ADVISER, to meet and
          perform their respective obligations and duties hereunder. Prompt
          notice of election to terminate shall be furnished by LIFE COMPANY
          with said termination to be effective upon receipt of notice;

  (d)     At the option of TRUST or ADVISER, upon the institution of formal
          proceedings against LIFE COMPANY and/or its broker-dealer affiliates

          ability to meet and perform its obligations and duties hereunder.
          Prompt notice of election to terminate shall be furnished by TRUST or
          ADVISER with said termination to be effective upon receipt of notice;

  (e)     In the event TRUST's Shares are not registered, issued or sold in

          of Contracts issued or to be issued by LIFE COMPANY termination shall
          be effective upon such occurrence without notice;

  (f)     In the event any Portfolio fails to qualify as a "regulated investment
          company" under Subchapter M of the Code or otherwise fails to meet the

          thereunder.  Termination shall be effective upon such occurrence
          without notice;

  (g)     At the option of TRUST and ADVISER if the Contracts cease to qualify
          as annuity contracts or life insurance contracts, as applicable, under

          Contracts may fail to so qualify. Termination shall be effective upon
          receipt of notice by LIFE COMPANY;

  (h)     At the option of LIFE COMPANY, upon  breach by TRUST or ADVISER of any

                                       13
<PAGE>
 
          satisfaction of LIFE COMPANY within ten days after written notice of
          such breach is delivered to TRUST or ADVISER;

  (i)     At the option of TRUST or ADVISER, upon LIFE COMPANY's breach of any
          material provision of this Agreement, which breach has not been cured
          to the satisfaction of TRUST or ADVISER within ten days after written
          notice of such breach is delivered to LIFE COMPANY;

  (j)     At the option of TRUST, if the Contracts are not registered, issued or
          sold in accordance with applicable federal and/or state law.
          Termination shall be effective immediately upon such occurrence
          without notice;

  (k)     In the event this Agreement is assigned without the prior written
          consent of LIFE COMPANY, TRUST, and ADVISER, termination shall be
          effective immediately upon such occurrence without notice.

  8.3     Notwithstanding any termination of this Agreement pursuant to Section
8.2 hereof, TRUST at its option may elect to continue to make available
additional TRUST Shares, as provided below, for so long as TRUST desires
pursuant to the terms and conditions of this Agreement, for all Contracts in
effect on the effective date of termination of this Agreement (hereinafter
referred to as "Existing Contracts"). Specifically, without limitation, if TRUST
so elects to make additional Shares available, the owners of the Existing
Contracts or LIFE COMPANY, whichever shall have legal authority to do so, shall
be permitted to reallocate investments in TRUST, redeem investments in TRUST
and/or invest in TRUST upon the payment of additional premiums under the
Existing Contracts. In the event of a termination of this Agreement pursuant to
Section 8.2 hereof, TRUST and ADVISER, as promptly as is practicable under the
circumstances, shall notify LIFE COMPANY whether TRUST elects to continue to
make Shares available after such termination.  If Shares continue to be made
available after such termination, the provisions of this Agreement shall remain
in effect and thereafter either TRUST or LIFE COMPANY may terminate the
Agreement, as so continued pursuant to this Section 8.3, upon sixty (60) days
prior written notice to the other Party.

  8.4     Except as necessary to implement Contract owner initiated
transactions, or as required by state insurance laws or regulations, LIFE
COMPANY shall not redeem the Shares attributable to the Contracts (as opposed to
the Shares attributable to LIFE COMPANY's assets held in the Separate Accounts),
and LIFE COMPANY shall not prevent Contract owners from allocating payments to a
Portfolio that is otherwise available under the Contracts until thirty (30) days
after the LIFE COMPANY shall have notified TRUST of its intention to do so.

                                          -------

writing to the other Party.

manner except by a written agreement properly authorized and executed by TRUST,
ADVISER and the LIFE COMPANY.

  10.10   No failure or delay by a Party in exercising any right or remedy under
this Agreement will operate as a waiver thereof and no single or partial
exercise of rights shall preclude a further or subsequent exercise. The rights
and remedies provided in this Agreement are cumulative and not exclusive of any
rights or remedies provided by law.

  IN WITNESS WHEREOF the Parties have caused their duly authorized officers to
execute this Agreement as of the date and year first above written.

Assistant Vice President and
Assistant Secretary
Life & Health Insurance Counsel
USAA Life Insurance Company
General Counsel - C3 West
9800 Fredricksburg Road, C-3-W
San Antonio, TX  78288

Dear Dwain:

USAA Life Insurance Company ("Life Company") will invest in one or more series
funds (each a "Portfolio") of the BT Insurance Funds Trust ("Trust"), which will
serve as an  underlying funding vehicle for certain variable annuity contracts
and variable life insurance policies (collectively, the "Contracts") issued by
Life Company, pursuant to a Fund Participation Agreement by and among the Life
Company, Trust and Bankers Trust Company, dated _________, 1998.  Bankers Trust
Company ("Bankers Trust") serves as the investment adviser to the Trust and in
such capacity provides investment advisory and administrative services to the
Trust and its Portfolios.

  Life Company hereby agrees to provide the services enumerated herein on a sub-
administration basis to owners of Contracts ("Contract Owners") who are
beneficial owners of shares of each Portfolio. Such services shall consist of
the following:

 1.  Providing necessary personnel and facilities to establish and maintain
     Contract Owner accounts and records.

 2.  Recording debits and credits to the accounts of Contract Owners.

 3.  Paying the proceeds of redemptions to Contract Owners either by check or by
     wire.

 4.  Furnishing Fund prospectuses, statements of additional information, proxy
     materials, annual and semi-annual reports to shareholders and other
     communications from the Fund to Contract Owners, as provided in Article 3.2
     of the Participation Agreement.
<PAGE>
 
 5.  Performing such shareholder servicing as may be required, which shall
     include but not be limited to, responding to questions regarding account
     balances and other account inquiries.

 6.  Federal and state income tax withholding and reporting.

 7.  Providing such other assistance and services as may reasonably be
     requested by the Fund.

  In recognition of Life Company providing such services and the administrative
cost savings to the Portfolios and the Trust, the Bankers Trust will pay Life
Company the fees set forth in Exhibit A hereto ("Fees").

  In the event that the investment advisory and/or administration fees paid by
the Portfolio to Bankers Trust are reduced by the Board of Trustees of the Trust
pursuant to an amendment of the applicable agreement, or, in the good faith
opinion of the Trust, based upon an opinion of counsel reasonably acceptable to
Life Company, such payments are, will or may be deemed to be in contravention or
violation of any law, rule, regulation, court decision or order, or out-of-court
settlement of actual or threatened litigation or enforcement position of any
regulatory body having jurisdiction over the Trust (taken together, "Change in
Law"), the Fees shall be adjusted accordingly to conform to such Change in Law
on terms and conditions deemed fair and equitable by Bankers Trust, and
acceptable to Life Company.  No Fee adjustment of any type, for any reason,
shall take effect until agreed upon, in writing, by both Bankers Trust and Life
Company.

  Bankers Trust shall give Life Company written notice 30 days prior to seeking
approval by the Board of Trustees of the Trust of (a) any increase in the fees
to be paid to Bankers Trust or (b) any reduction or elimination of Bankers
Trust's voluntary fee waiver as reflected in Exhibit B hereto.

  Either party may terminate this Agreement, without penalty, on 60 days'
written notice to the other party; except that the Fees set forth in Exhibit A
shall continue as long as the assets underlying the Contracts issued by Life
Company are allocated to the Trust. Unless so terminated, this Agreement shall
continue in effect for so long as Bankers Trust, or its successor(s) in
interest, continues to perform in an advisory capacity for the Trust and for so
long as any Contract values or any monies attributable to Life Company are in
the Trust.

  Each party hereto shall indemnify and hold harmless ("Indemnifying Party") the
other party and each of its officers, directors, trustees, employees, and agents
(and former officers, directors, trustees, employees, and agents) and each
person, if any, who controls such other party within the meaning of Section 15
of the Securities Act of 1933 (individually and collectively,  "Indemnified
Party") from and against any and all losses, claims, damages, liabilities,
costs, and expenses (including reasonable attorneys' fees) ("Losses") arising
out of (i) any violation by the Indemnifying Party of any law, rule, regulation,
court order or enforcement position of any regulatory body having jurisdiction
over either party, (ii) the Indemnifying Party's performance of or failure to
perform its obligations under, or in connection with this Agreement, except that
an Indemnifying Party shall have no liability to the extent such Losses result
from the willful
<PAGE>
 
misfeasance, bad faith, negligence, reckless disregard of obligations or duties
under this Agreement, or breach of this Agreement by an Indemnified Party. In no
event shall any party be liable for any special, consequential, or incidental
damages. The indemnification under this Agreement is in addition to (and not
duplicative of), and not in lieu of; any indemnification provided under any Fund
Participation Agreement entered into between the parties.

  If you are in agreement with the foregoing, please sign a copy and return it
to the undersigned.

[LETTERHEAD OF USAA LIFE INSURANCE COMPANY]

                                 July 21, 1994

Board of Directors 
USAA Life Insurance Company
9800 Fredericksburg Road
San Antonio, Texas 78288


Board of Directors:

        This option is furnished in connection with the filing by the USAA Life 
Insurance Company ("USAA LIFE") and the Separate Account of USAA LIFE ("Separate
Account") of a registration statement under the Securities Act of 1933 (the 
"1933 Act") and under the Investment Company Act of 1940 on Form N-4 
("Registration Statement"). The securities being registered under the 
Registration Statement are units of interest ("Units") to be issued by the 
Separate Account pursuant to certain individual flexible premium variable 
annuity contracts (the "Contracts"), described in the Registration Statement.

        I have examined the Articles of Incorporation and Bylaws of USAA LIFE 
and such corporate records and other documents and such laws as I consider 
necessary and appropriate as a basis for the opinion hereinafter expressed. I 
have examined the form of the Registration Statement to be filed with the 
Securities and Exchange Commission in connection with the registration under the
1933 Act of an indefinite number of Units. I am familiar with the proceedings 
taken and proposed to be taken in connection with the authorization, issuance, 
and sale of the Units. On the basis of my examination of these documents and 
such laws that I consider appropriate, it is my opinion that:

        1. USAA LIFE is a corporation duly organized and validly existing under 
the laws of Texas.

        2. The Separate Account was duly created pursuant to the provisions of 
Chapter 3, Article 3.75 of the Texas Insurance Code.

        3. Under Texas law, the income, gains and losses, whether or not 
realized, from assets allocated to the Separate Account must be credited to or 
charged against such Account, without regard to the other income, gains or 
losses of USAA LIFE.

        4. The portion of the assets to be held in the Separate Account equal to
the reserves and other liabilities under the Contracts will not be chargeable 
with liabilities arising out of any other business USAA LIFE may conduct.

        5. The Contracts have been duly authorized by USAA LIFE and, when issued
in the manner contemplated by the Registration Statement, the Units thereunder 
will constitute validly issued and binding obligations of USAA LIFE in 
accordance with the terms of the Contracts.

        I hereby consent to the filing of this opinion as an Exhibit to the 
Registration Statement and to the reference to me under the caption "Legal 
Matters" in the Statement of Additional Information contained in the 
Registration Statement. On giving this consent, I do not admit that I am in the 
category of persons whose consent is required under Section 7 of the 1933 Act or
the rules and regulations of the Securities and Exchange Commission thereunder.

Respectfully submitted,

                                 SUBSCRIPTION AGREEMENT



  This Subscription Agreement (the "Agreement") between USAA Life Insurance
Company (hereinafter "USAA LIFE"), a stock life insurance company existing under
and by virtue of the laws of the State of Texas, on behalf of the Separate
Account of USAA LIFE Insurance Company ("Separate Account"), and USAA Life
Investment Trust (hereinafter the "Trust"), a business trust organized and
existing under and by virtue of the laws of the State of Delaware.

  In consideration of the mutual promises set forth herein, the parties agree as
follows:

  1. The Trust agrees to sell to USAA LIFE, for the Separate Account, and USAA
LIFE agrees to purchase, on behalf of the Separate Account, for the aggregate
amount of $81,000,000.00, shares of beneficial interest of the five existing
series ("Funds") of the Trust (hereinafter the "Shares") at a price of ten
dollars ($10.00) per Share for each Fund, except the Money Market Fund, for
which the price is one dollar ($1.00) per Share, in the following amounts:


         2,100,000 Shares of USAA Life Variable Annuity Money Market Fund
         2,000,000 Shares of USAA Life Variable Annuity Income Fund
         2,000,000 Shares of USAA Life Variable Annuity Growth and Income Fund
         1,890,000 Shares of USAA Life Variable Annuity World Growth Fund
         2,000,000 Shares of USAA Life Variable Annuity Diversified Assets Fund

  Such sale and purchase will be consummated following the effectiveness of the
Trust's Form N-1A registration statement filed with the Securities and Exchange
Commission under the Securities Act of 1933 and prior to the commencement of the
Trust's offering of its Shares to the Separate Account.

  2.  USAA LIFE acknowledges that the Shares have not been registered under any
state or federal securities laws and that, therefore, the Trust is relying on
certain exemptions therein from such registration requirements, including
exemptions dependent on the intent of the undersigned in acquiring the Shares.
USAA LIFE also understands that any resale of the Shares, or any part thereof,
may be subject to restrictions under state and federal securities laws, and that
USAA LIFE may be required to bear the economic risk of an investment in the
Shares for an indefinite period of time.

  3.  USAA LIFE represents and warrants that it is acquiring the Shares solely
for its own account and solely for investment purposes and not with a view to
the resale or disposition of all or any part thereof, and that it has no present
plan or intention to sell or otherwise dispose of the Shares or any part
thereof.

  4.  USAA LIFE agrees that it will not sell or dispose of the Shares or any
part thereof unless registration statements with respect to such Shares are then
in effect under the Securities Act of 1933 and under any applicable state
securities laws or unless the undersigned
<PAGE>
 
shall have delivered to the Trust an opinion of counsel acceptable to the Trust,
in form and substance acceptable to the Trust, that no such registration is
necessary.

  5.  USAA LIFE further agrees to withdraw any request to redeem any of the
Shares to the extent the Trust informs the undersigned that the effect of such
redemption could have a material adverse effect on the Funds.

  6.  The parties acknowledge, with respect to the foregoing, that USAA Life
will bear the organizational expenses of the Trust.

  IN WITNESS THEREOF, the parties hereto have executed this Agreement by their
duly authorized representatives this 16th day of December, 1994.
