FUND OBJECTIVES, STRATEGIES, AND RISKS

USAA LIFE MONEY MARKET FUND

OBJECTIVE

The highest level of current income consistent with preservation of capital and
maintenance of liquidity.

PRINCIPAL INVESTMENT STRATEGY

The  Fund's principal  investment  strategy  is to invest  the Fund's assets in
high-quality,  U.S.  dollar-denominated debt securities of domestic and foreign
issuers that have been  determined to present  minimal  credit risk,  which may
include the following:

   *  obligations of the U.S. Government, its agencies and instrumentalities,
      and repurchase agreements collateralized by such obligations;
   *  short-term corporate debt obligations such as notes, bonds, and 
      commercial paper;
   *  U.S. bank or foreign bank obligations, including certificates of deposit,
      banker's acceptances, and time deposits;
   *  obligations of state and local governments and their agencies and 
      instrumentalities;
   *  municipal lease obligations;
   *  mortgage-backed securities;
   *  asset-backed securities;
   *  master demand notes;
   *  Eurodollar obligations;
   *  Yankee obligations; and 
   *  other short-term debt securities.

The SEC has set certain  diversification  requirements  for money market funds.
Generally,  these  requirements  limit a money  market  fund's  investments  in
securities of any issuer to no more than 5% of the fund's assets.  Also, strict
SEC  guidelines  do not permit us to invest,  with respect to 75% of the Fund's
assets,  greater  than 10% of the  Fund's  assets  in  securities  issued by or
subject to guarantees by the same  institution.  Purchases of securities issued
or guaranteed by the U.S. Government or its agencies or  instrumentalities  are
not counted toward these limitations.

The Fund's  investments  consist of  high-quality  securities  that  qualify as
"first-tier"  securities  under the SEC rules that apply to money market funds.
In general, a first-tier security is defined as a security that is:

   *  issued or guaranteed by the U.S. Government or any agency or 
      instrumentality thereof;

   *  rated  or  subject  to a  guarantee  that is  rated  in the  highest
      category  for  short-term  securities  by at  least  two  Nationally
      Recognized  Statistical  Rating  Organizations  (NRSROs),  or by one
      NRSRO if the security is rated by only one NRSRO;

   *  unrated but issued by an issuer or  guaranteed by a  guarantor  that
      has other comparable short-term obligations so rated; or

   *  unrated but determined by us to be of comparable quality.

In addition,  we must consider whether a particular investment presents minimal
credit risk. Current NRSROs include:

   *  Moody's Investors Service, Inc.;  *  Standard & Poor's Ratings Group; and
   *  Fitch IBCA, Inc.;                 *  Duff & Phelps Inc.
   *  Thompson BankWatch, Inc.;

If the rating of a security is downgraded  after  purchase,  we will  determine
whether it is in the best  interest of the Fund's  shareholders  to continue to
hold the security in the Fund's portfolio.

We balance  factors  such as credit  quality and  maturity to purchase the best
relative  value  available  in the market at any given time.  While rare,  sell
decisions  are  usually  based on a change in our  credit  analysis  or to take
advantage of an opportunity to reinvest at a higher yield.

MAIN RISKS

While we will  endeavor to  maintain a constant  Fund net asset value of $1 per
share,  there  is no  assurance  that we will be able to do so.  Remember,  the
shares are neither insured nor guaranteed by the U.S. Government.  As such, the
Fund  carries  some  risk.  The  primary  risks of  investing  in this Fund are
interest rate risk and credit risk.

INTEREST  RATE RISK  involves  the  possibility  that the  value of the  Fund's
investments will fluctuate because of changes  in interest rates. We attempt to
minimize  this  interest rate risk by limiting the maturity of each security to
397 days or less and maintaining a dollar-weighted  average portfolio  maturity
for the Fund of 90 days or less. In fact,  we typically  invest in money market
instruments  with  relatively  short  maturities  primarily to  facilitate  the
redemption  of Fund shares  following  the "Free Look" period  described in the
accompanying  variable  annuity  contract or  variable  life  insurance  policy
prospectus.

   *  IF INTEREST  RATES  INCREASE:  the yield of the Fund may increase,  which
      would likely increase the Fund's total return.

   *  IF INTEREST RATES DECREASE: the yield of the Fund may decrease, which may
      decrease the Fund's total return.

                                       4B
<PAGE>

CREDIT  RISK  involves  the  possibility  that a borrower  cannot  make  timely
interest and principal payments on its securities.  We attempt to minimize this
credit risk by investing only in securities  rated in the highest  category for
short-term securities,  or, if not rated, of comparable quality, at the time of
purchase.  Additionally,  we will not  purchase a security  unless our analysts
have determined that the security presents minimal credit risk.

Money market funds are  sometimes  confused  with savings  accounts.  A savings
account is a deposit  with a bank.  The bank is  obligated to return the amount
deposited  and to pay you interest  for the use of your money.  Up to a certain
dollar amount,  the Federal Deposit  Insurance  Corporation  (FDIC) will insure
that the bank meets its obligations.

The Fund is not a savings  account but,  rather,  is a money market mutual fund
that  issues and  redeems  its shares at the Fund's net asset  value  (NAV) per
share.  The Fund always seeks to maintain a constant NAV of $1 per share.  Just
as a savings  account  pays  interest  on the amount  deposited,  the Fund pays
dividends  on Fund  shares.  The value of an  account  will grow over time when
these dividends are reinvested in the Fund.

WHO SHOULD CONSIDER INVESTING IN THIS FUND

This Fund is designed  for the  investor  seeking to benefit  from money market
yields  consistent  with safety of  principal.  The Fund does not  constitute a
balanced investment program, but can be used in conjunction with other funds as
a component for the conservative  investor for a long-term balanced  investment
program. The securities in which the USAA Life Money Market Fund may invest may
not  yield as high a level of  income  as  securities  with a lesser  degree of
credit safety and liquidity or longer-term debt obligations.  Accordingly,  the
Fund is expected to provide a lower level of income and risk than other  mutual
funds, such as the USAA Life Income Fund.

FUND PERFORMANCE

The bar chart shown below  illustrates  the Fund's  volatility and  performance
from year to year over the life of the Fund,  while the table  shows the Fund's
average annual total returns for the one-year period as well as the life of the
Fund. Remember,  historical performance does not necessarily indicate what will
happen in the future.  Also keep in mind, the total return  calculations do not
include other costs associated with the annuity or life insurance  policy;  and
if they did, the Fund's performance would be lower.

[SIDE BARS]
TOTAL RETURN MEASURES THE PRICE CHANGE IN A SHARE ASSUMING THE  REINVESTMENT OF
ALL DIVIDEND INCOME AND CAPITAL GAIN DISTRIBUTIONS.

YIELD IS THE ANNUALIZED  NET INCOME OF THE FUND DURING A SPECIFIED  PERIOD AS A
PERCENTAGE OF THE FUND'S SHARE PRICE.

EFFECTIVE YIELD IS CALCULATED SIMILAR TO THE YIELD,  HOWEVER,  WHEN ANNUALIZED,
THE INCOME EARNED IS ASSUMED TO BE REINVESTED.

All mutual funds must use the same  formulas to calculate  yield and  effective
yield. The Fund typically advertises  performance in terms of a 7-day yield and
effective yield and may advertise total return.  The 7-day yield quotation more
closely reflects current earnings of the Fund than the total return  quotation.
The  effective  yield will be  slightly  higher  than the yield  because of the
compounding  effect of the assumed  reinvestment.  Current yields and effective
yields  fluctuate  daily and will vary with factors such as interest  rates and
the quality,  length of  maturities,  and type of investments in the portfolio.
The Fund's 7-day yield for the period ended December 31, 1998, was 5.00%.

USAA LIFE INCOME FUND

OBJECTIVE

Maximum current income without undue risk of principal.

PRINCIPAL INVESTMENT STRATEGY

The  Fund's  principal  investment  strategy  is to invest  the  Fund's  assets
primarily in U.S.  dollar-denominated  securities  that have been  selected for
their high yields  relative to the risk involved.  Consistent with this policy,
when  interest  rates  rise,  we will  invest a greater  portion  of the Fund's
portfolio in securities whose value we believe to be less sensitive to interest
rate changes. The Fund's portfolio may consist of any of the following:

   *  obligations of the U.S. Government, its agencies  and instrumentalities,
      and repurchase agreements collateralized by such obligations;
   *  mortgage-backed securities;
   *  asset-backed securities;
   *  corporate debt securities such as notes, bonds, and commercial paper;
   *  U.S. bank obligations, including certificates of deposit and banker's 
      acceptances;                    
   *  obligations of state and local governments and their agencies and 
      instrumentalities;
   *  master demand notes;
   *  Eurodollar obligations;
   *  Yankee obligations;
   *  other debt securities;
   *  convertible securities;
   *  equity and debt securities of real estate investment trusts;
   *  common stocks; and
   *  preferred stocks.

The  debt  securities  must  be  investment  grade  at the  time  of  purchase.
Investment-grade  securities are those  securities  issued or guaranteed by the
U.S. Government, its agencies and instrumentalities;  those rated or subject to
a guarantee that is rated within the four highest  long-term rating  categories
by:

   *  Moody's Investors Services, Inc.,  *  Standard & Poor's Ratings Group, or
   *  Fitch IBCA, Inc.,                  *  Duff and Phelps;

or, if unrated by these agencies,  we must determine that these  securities are
of equivalent  investment quality.  You will find a complete description of the
above debt ratings in the Statement of Additional Information.

If the rating of a security  is  downgraded  below  investment  grade,  we will
determine  whether it is in the best  interest  of the Fund's  shareholders  to
continue to hold the security in the Fund's portfolio.  If downgrades result in
more than 5% of the Fund's net assets  being  invested in  securities  that are
less than investment-grade quality, we will take immediate action to reduce the
Fund's  holdings  in such  securities  to 5% or less of the Fund's net  assets,
unless otherwise directed by the Board of Trustees.

In deciding  which  securities to buy and sell, we search for  securities  that
represent value at the time given current market  conditions.  For fixed income
securities,  value  is  a  combination  of  yield,  credit  quality,  structure
(maturity,  coupon,  redemption features), and liquidity.  Recognizing value is
the result of  simultaneously  analyzing the interaction of these factors among
the  securities  available in the market.  We will sell a security if we become
concerned  about its  credit  risk,  we are  forced by market  factors to raise
money, or an attractive  replacement security is available.  For common stocks,
value involves selecting  dividend-paying stocks, whose yields are sensitive to
interest rate levels when their dividend yields are close to bond yields, which
implies undervaluation. Such stocks are generally sold when their yields return
to a normal relationship versus bonds through price appreciation.

As a temporary  defensive measure because of market,  economic,  political,  or
other  conditions,   we  may  invest  up  to  100%  of  the  Fund's  assets  in
investment-grade, short-term debt instruments. This  may result in the Fund not
achieving  its  investment  objective  during the time it is in this  temporary
defensive posture.

MAIN RISKS

The primary risks of investing in this Fund are interest rate risk,  prepayment
risk, credit risk, and market risk.

INTEREST  RATE RISK  involves  the  possibility  that the  value of the  Fund's
investments will fluctuate because of changes in interest rates.

   *  IF  INTEREST RATES  INCREASE:  the yield of the Fund may increase and the
      market  value of the Fund's  securities  will likely  decline,  adversely
      affecting the net asset value and total return.

   *  IF  INTEREST RATES  DECREASE:  the yield of the Fund may decrease and the
      market  value of the Fund's  securities may increase,  which would likely
      increase the Fund's net asset value and total return.

The price  volatility  of a bond also depends on its maturity.  Generally,  the
longer the maturity of a bond, the greater its  sensitivity to interest  rates.
To  compensate  investors  for this higher risk,  bonds with longer  maturities
generally offer higher yields than bonds with shorter maturities.

PREPAYMENT  RISK involves the  possibility  that  prepayments of mortgages will
affect  mortgage-backed  securities  held in the Fund's  portfolio  and require
reinvestment at lower interest rates,  resulting in less interest income to the
Fund.

                                       6B
<PAGE>

CREDIT  RISK  involves  the  possibility  that a borrower  cannot  make  timely
interest and principal  payments on its securities.  We attempt to minimize the
Fund's credit risk by investing in securities  considered  investment  grade at
the time of purchase.  When evaluating potential  investments for the Fund, our
analysts  also  assess  credit  risk and its  impact on the  Fund's  portfolio.
Nevertheless, even investment-grade securities are subject to some credit risk.
Securities in the  lowest-rated,  investment-grade  category  have  speculative
characteristics. Changes in economic conditions or other circumstances are more
likely to lead to a weakened capability to make principal and interest payments
on these securities than is the case for higher-rated securities.  In addition,
the ratings of securities  are  estimates by the rating  agencies of the credit
quality of the  securities.  The ratings may not take into  account  every risk
related to whether interest or principal will be repaid on a timely basis.

MARKET RISK  involves the  possibility  that the Fund's  investments  in equity
securities  will  decline in a down  stock  market,  reducing  the value of the
company's  stock,  regardless  of the  success  or  failure  of  the  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

An  additional  risk  of the  Fund  is the  risk of  investing  in real  estate
investment trusts (REITs).

REITs.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  Additionally,  REITs are
dependent  upon  the  capabilities  of  the  REIT   manager(s),   have  limited
diversification, and could be significantly impacted by changes in tax laws.

WHO SHOULD CONSIDER INVESTING IN THIS FUND

This Fund is designed  primarily  for the  investor  seeking to benefit  from a
level of income higher than that  available in the USAA Life Money Market Fund.
An  investor  in  this  Fund  should  also  be  willing  to  accept   principal
fluctuation.  Similar to the USAA Life Money Market Fund,  the USAA Life Income
Fund should not be relied upon as a complete investment program.

FUND PERFORMANCE

The bar chart shown below  illustrates  the Fund's  volatility and  performance
from year to year over the life of the Fund,  while the table  shows the Fund's
average annual total returns for the one-year period as well as the life of the
Fund. Remember,  historical performance does not necessarily indicate what will
happen in the future.  Also keep in mind, the total return  calculations do not
include other costs associated with the annuity or life insurance  policy;  and
if they did, the Fund's performance would be lower.

USAA LIFE GROWTH AND INCOME FUND

OBJECTIVE

Capital growth and current income.

PRINCIPAL INVESTMENT STRATEGY

The  Fund's  principal  investment  strategy  is to invest  the  Fund's  assets
primarily  in  dividend-paying  equity  securities.  We use  the  term  "equity
securities"  to include  common  stocks,  securities  convertible  into  common
stocks,  securities that carry the right to buy common stocks,  and real estate
investment  trusts (REITs).  We will limit the Fund's investment in convertible
securities  to 5% of the  value of the  Fund's  net  assets  at the time  these
securities are purchased.  We may also invest in nonconvertible debt securities
and nonconvertible preferred stock.

Additionally,  we may invest up to 30% of the Fund's  total  assets in American
Depositary Receipts (ADRs) or similar forms of ownership interest in securities
of foreign  issuers  deposited  with a  depositary,  and  securities of foreign
issuers   that  are   traded   on  U.S.   securities   exchanges   or  in  U.S.
over-the-counter markets.

In deciding  which  securities  to buy and sell, we appraise a stock's price in
relation to the company's  earnings,  cash flow, book value, and yield. We also
consider various qualitative factors such as the number of shares the company's
management  owns, the attitude of investors in general toward the company,  and
the  quality  of  management.  We use  the  same  criteria  in  deciding  which
securities to sell. For example,  when a company's shares sell well above their
relative historical levels of valuation, we may decide to sell the stock.

As a temporary  defensive measure because of market,  economic,  political,  or
other  conditions,   we  may  invest  up  to  100%  of  the  Fund's  assets  in
investment-grade, short-term debt instruments. This  may result in the Fund not
achieving  its  investment  objective  during the time it is in this  temporary
defensive posture.

MAIN RISKS

The primary risk of investing in this Fund is market risk.

MARKET RISK  involves the  possibility  that the Fund's  investments  in equity
securities  will  decline in a down  stock  market,  reducing  the value of the
company's  stock,  regardless  of the  success  or  failure  of  the  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

Other risks of the Fund include the risks of foreign investing and investing in
real estate investment trusts (REITs).

FOREIGN  INVESTING.  Investing in  securities  of foreign  issuers poses unique
risks:  currency  exchange  rate  fluctuations;   increased  price  volatility;
different accounting,  reporting, and disclosure requirements; and political or
social instability. In the past, equity and debt instruments of foreign issuers
have been more volatile than equity and debt instruments of U.S. issuers.

REITs.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  Additionally,  REITs are
dependent  upon  the  capabilities  of  the  REIT   manager(s),   have  limited
diversification, and could be significantly impacted by changes in tax laws.

WHO SHOULD CONSIDER INVESTING IN THIS FUND

This Fund is designed for the investor seeking to benefit from long-term growth
of capital  and  income.  Because  the Fund  emphasizes  investments  in common
stocks, its value will fluctuate based on market conditions.  Consequently, the
USAA Life  Growth and Income  Fund  should  not be relied  upon for  short-term
financial needs or short-term investment in the stock market.

USAA LIFE WORLD GROWTH FUND

OBJECTIVE

Long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGY

The  Fund's  principal  investment  strategy  is to invest  the  Fund's  assets
primarily in equity securities of both foreign and domestic issuers and in real
estate  investment  trusts  (REITs).  We use the term  "equity  securities"  to
include common stocks,  preferred  stocks,  securities  convertible into common
stocks, and securities that carry the right to buy common stocks. We may invest
the  remainder  of the  Fund's  assets  in  investment-grade,  short-term  debt
instruments having the following characteristics:

   *  remaining  maturities of less than one year that have been issued or
      guaranteed as to both principal and interest by the U.S. Government or
      its agencies or instrumentalities, or

   *  repurchase agreements collateralized by such securities.

There  are no  restrictions  as to the types of  businesses  or  operations  of
companies in which the Fund's  assets may be  invested,  except that we may not
invest more than 25% of the Fund's total assets in one  industry.  Under normal
market conditions, the Fund's investments will be diversified in at least three
countries.

We believe that international  diversification may have a balancing impact with
regard to domestic  investments  during periods of adverse  economic and market
conditions in the United States. Therefore, the Fund combines the advantages of
investing in a diversified  international  market and domestic market, with the
convenience and liquidity of a mutual fund based in the United States.

In deciding which foreign  securities to buy and sell, we review  countries and
regions for economic and political stability as well as future prospects.  Then
we research  individual  companies  looking for  favorable  valuations,  growth
prospects,  quality of management, and industry outlook. Securities are sold if
we  believe  they  are  overvalued  or if the  economic  or  political  outlook
significantly deteriorates.

In deciding which domestic  securities to buy and sell, we generally  invest in
companies  that  are,  or have the  prospect  of  becoming,  dominant  in their
industry.  We expect the sales and  earnings of these  companies to grow faster
than those of their industry  peers.  We consider a number of factors such as a
company's  strategic position in its industry,  sales and earnings growth, cash
flow, book value,  and dividend yield. We will sell a security when we perceive
that our original investment thesis no longer holds.

As a temporary  defensive measure because of market,  economic,  political,  or
other  conditions,   we  may  invest  up  to  100%  of  the  Fund's  assets  in
investment-grade, short-term debt instruments. This  may result in the Fund not
achieving  its  investment  objective  during the time it is in this  temporary
defensive posture.

MAIN RISKS

The primary  risks of  investing  in this Fund are market risk and the risks of
foreign investing.

MARKET RISK  involves the  possibility  that the Fund's  investments  in equity
securities  will  decline in a down  stock  market,  reducing  the value of the
company's  stock,  regardless  of the  success  or  failure  of  the  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

FOREIGN INVESTING RISK involves the possibility that the Fund's  investments in
foreign  stock,  including  American  Depositary  Receipts  (ADRs)  and  Global
Depositary  Receipts  (GDRs),  will decrease  because of the  following  unique
risks: currency exchange rate fluctuations; foreign market illiquidity; control
regulations;   foreign  ownership  limits;   uncertain  political   conditions;
different accounting,  reporting, and disclosure requirements; and difficulties
in obtaining  legal  judgments.  In the past,  equity and debt  instruments  of
foreign  markets have been more  volatile than equity and debt  instruments  of
U.S. securities markets.

   *  EMERGING  MARKETS  RISK. A country  that is in the initial  stages of its
      industrial  cycle  is  considered  to be  an  emerging  markets  country.
      Investments  in  developing   countries   involve  exposure  to  economic
      structures  that are generally less diverse and mature than in the United
      States and to political  systems  which may be less stable.  In the past,
      markets of developing  countries have been more volatile than the markets
      of developed countries.

   *  POLITICAL  RISK.  Political  risk includes a greater  potential for coups
      d'etat,  revolts,  and expropriation by governmental  organizations.  For
      example,  we may invest the  Fund's  assets in Eastern  Europe and former
      states of the Soviet Union (also known as the Commonwealth of Independent
      States or CIS).  These countries were under  communist  systems which had
      nationalized private industry. There is no guarantee that nationalization
      may not occur  again in this  region or others in which we may invest the
      Fund's  assets,  in which  case,  we may  lose all or part of the  Fund's
      investment in that country's issuers.

   *  EURO CONVERSION RISK. Beginning January 1, 1999, countries  participating
      in the European  Monetary Union began  converting their currencies into a
      new currency unit called the Euro. The conversion to the Euro, which will
      continue in stages  through  2002,  is expected to reshape the  financial
      markets, banking systems, and monetary policies in Europe and


                                      10B
<PAGE>

      other  parts  of  the  world  and  could  adversely   affect  the  Fund's
      investments in these markets. In addition,  a failure of the clearing and
      settlement  systems in these markets to handle the Euro conversion  could
      adversely affect the Fund.

An  additional  risk  of the  Fund  is the  risk of  investing  in real  estate
investment trusts (REITs).

REITs.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  Additionally,  REITs are
dependent  upon  the  capabilities  of  the  REIT   manager(s),   have  limited
diversification, and could be significantly impacted by changes in tax laws.

WHO SHOULD CONSIDER INVESTING IN THIS FUND

This Fund is designed  for the  investor  seeking to  diversify by investing in
securities of both domestic and foreign issuers and who is prepared to bear the
risks of such investments.  Because of the Fund's emphasis on equity securities
and securities of foreign  issuers,  the USAA Life World Growth Fund should not
be relied upon as a complete investment program.

USAA LIFE DIVERSIFIED ASSETS FUND

OBJECTIVE

Long-term capital growth,  consistent with preservation of capital and balanced
by current income.

PRINCIPAL INVESTMENT STRATEGY

The Fund's principal investment strategy is to provide a diversified investment
program within one mutual fund by allocating  the Fund's  assets,  under normal
market conditions,  in approximately 60% equity securities  (selected for their
potential   return)  and  approximately  40%  in  debt  securities  of  varying
maturities.  We use the term  "equity  securities"  to include  common  stocks,
preferred  stocks,  securities  convertible into common stocks,  and securities
that  carry the right to buy  common  stocks.  The  equity  securities  consist
primarily  of "basic  value  stocks"  of U.S.  companies  that we  believe  are
undervalued in relation to such factors as the company's  assets and current or
prospective  earnings.  We may also invest the Fund's  assets in shares of real
estate investment trusts (REITs).

The fixed  income  component  of the Fund will be made up of the same  types of
debt  securities  in which the USAA Life Income  Fund may invest.  The Fund may
also invest in municipal lease obligations.

From time to time the stock and bond  markets may  fluctuate  independently  of
each  other.  In other  words,  a decline in the stock  market  may, in certain
instances,  be offset by a rise in the bond market, or vice versa. As a result,
the Fund,  with  its mix of stocks and  bonds, may in the long  run potentially
return  less (and  entail  less  market  risk)  than  a  mutual  fund investing
exclusively in stocks.

In deciding  which  equity  securities  to buy and sell,  we appraise a stock's
price in relation to the company's earnings,  cash flow, book value, and yield.
We also consider various  qualitative  factors such as the number of shares the
company's  management  owns,  the attitude of  investors in general  toward the
company,  and the quality of  management.  We use the same criteria in deciding
which securities to sell. For example,  when a company's shares sell well above
their relative historical levels of valuation, we may decide to sell the stock.

In deciding  which debt  securities to buy and sell,  we search for  securities
that represent  value at the time given current market  conditions.  Value is a
combination of yield, credit quality,  structure (maturity,  coupon, redemption
features),  and liquidity.  Recognizing  value is the result of  simultaneously
analyzing the  interaction of these factors among the  securities  available in
the  market.  We will sell a security if we become  concerned  about its credit
risk,  we are  forced  by  market  factors  to raise  money,  or an  attractive
replacement is available.

As a temporary  defensive measure because of market,  economic,  political,  or
other  conditions,   we  may  invest  up  to  100%  of  the  Fund's  assets  in
investment-grade, short-term debt instruments. This  may result in the Fund not
achieving  its  investment  objective  during the time it is in this  temporary
defensive posture.

MAIN RISKS

The primary risks of investing in this Fund are market risk,  credit risk,  and
interest rate risk.

MARKET RISK involves the possibility that the Fund's investments in stocks will
decline in a down stock  market,  reducing  the value of the  company's  stock,
regardless of the success or failure of the company's operations.  Stock prices
in general may decline over short or even extended  periods,  regardless of the
success or failure of a  company's  operations.  Stock  markets  tend to run in
cycles,  with  periods  when  stock  prices  generally  go up,  known as "bull"
markets, and periods when stock prices generally go down, referred to as "bear"
markets. Equity securities tend to go up and down more than bonds.

CREDIT  RISK  involves  the  possibility  that a borrower  cannot  make  timely
interest and principal  payments on its securities.  We attempt to minimize the
Fund's credit risk by investing in securities  considered  investment  grade at
the time of purchase.  When evaluating potential  investments for the Fund, our
analysts  also  assess  credit  risk and its  impact on the  Fund's  portfolio.
Nevertheless, even investment-grade securities are subject to some credit risk.
Securities in the  lowest-rated,  investment-grade  category  have  speculative
characteristics. Changes in economic conditions or other circumstances are more
likely to lead to a weakened capability to make principal and interest payments
on these securities than is the case for higher-rated securities.  In addition,
the ratings of securities  are  estimates by the rating  agencies of the credit
quality of the  securities.  The ratings may not take into  account  every risk
related to whether interest or principal will be repaid on a timely basis.

INTEREST  RATE RISK  involves  the  possibility  that the  value of the  Fund's
investments will fluctuate because of changes in interest rates.

   *  IF INTEREST  RATES  INCREASE:  the yield of the Fund may increase and the
      market  value of the Fund's  securities  will likely  decline,  adversely
      affecting the net asset value and total return.

   *  IF INTEREST  RATES  DECREASE:  the yield of the Fund may decrease and the
      market value of the Fund's  securities  may increase,  which would likely
      increase the Fund's net asset value and total return.

                                      12B
<PAGE>

The price  volatility  of a bond also depends on its maturity.  Generally,  the
longer the maturity of a bond, the greater its  sensitivity to interest  rates.
To  compensate  investors  for this higher risk,  bonds with longer  maturities
generally offer higher yields than bonds with shorter maturities.

Other risks of the Fund include the risk of investing in real estate investment
trusts (REITs) and prepayment risk.

REITs.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  Additionally,  REITs are
dependent  upon  the  capabilities  of  the  REIT   manager(s),   have  limited
diversification, and could be significantly impacted by changes in tax laws.

PREPAYMENT  RISK involves the  possibility  that  prepayments of mortgages will
affect  mortgage-backed  securities  held in the Fund's  portfolio  and require
reinvestment at lower interest rates,  resulting in less interest income to the
Fund.

WHO SHOULD CONSIDER INVESTING IN THIS FUND

This Fund is designed for the investor  seeking the benefits of both  long-term
capital  appreciation and current income.  Generally,  this Fund is expected to
have less  exposure to equity  securities  than the USAA Life Growth and Income
Fund.

USAA LIFE AGGRESSIVE GROWTH FUND

OBJECTIVE

Appreciation of capital.

PRINCIPAL INVESTMENT STRATEGY

The  Fund's  principal  investment  strategy  is to invest  the  Fund's  assets
primarily  in equity  securities  of  companies  with the  prospect  of rapidly
growing  earnings.   These  investments  will  tend  to  be  made  in  smaller,
less-recognized  companies,  but may  include  larger,  more  widely recognized
companies  as well.  We use the term  "equity  securities"  to  include  common
stocks,  preferred  stocks,  securities  convertible  into common  stocks,  and
securities that carry the right to buy common stocks.  We may also invest up to
10% of the Fund's assets in shares of real estate investment trusts (REITs).

While most of the Fund's  assets will be invested  in U.S.  securities,  we may
also  invest  up to  30% of the  Fund's  total  assets  in  foreign  securities
purchased in either foreign or U.S. markets. These foreign holdings may include
securities  issued  in  emerging  markets  as  well  as  securities  issued  in
established markets.

We will not  generally  trade the Fund's  securities  for  short-term  profits;
however,  if  circumstances  warrant,  we may purchase and sell Fund securities
without regard to the length of time held. The Fund's  portfolio  turnover rate
will vary from year to year depending on market  conditions,  and it may exceed
100%. Because a high turnover rate increases transaction costs and may increase
taxable  capital gains,  we will carefully  weigh the  anticipated  benefits of
trading.

In  deciding  which  securities  to buy and  sell,  we tend to  invest in small
capitalization  companies that have rapid sales and earnings growth  potential.
We seek  companies  that are well  positioned  to take  advantage  of  emerging
long-term  social and  economic  trends and have ample  financial  resources to
sustain their growth. We may reduce or sell the Fund's investments in companies
if their  stock  prices  appreciate  excessively  in  relation  to  fundamental
prospects.  We will sell or reduce large capitalization  equity holdings in the
portfolio if those  holdings  comprise an excessive  weighting of total assets.
Companies  will also be sold if they fail to realize their growth  potential or
if there are more attractive opportunities elsewhere.

As a temporary  defensive measure because of market,  economic,  political,  or
other  conditions,   we  may  invest  up  to  100%  of  the  Fund's  assets  in
investment-grade, short-term debt instruments. This  may result in the Fund not
achieving  its  investment  objective  during the time it is in this  temporary
defensive posture.

MAIN RISKS

The primary  risks of  investing  in this Fund are market risk and the risks of
investing in companies with small market capitalizations (small cap companies).

[SIDE BAR]
MARKET  CAPITALIZATION  IS  THE  TOTAL  RETURN  MARKET  VALUE  OF  A  COMPANY'S
OUTSTANDING SHARES OF COMMON STOCK.

MARKET RISK  involves the  possibility  that the Fund's  investments  in equity
securities  will  decline in a down  stock  market,  reducing  the value of the
company's  stock,  regardless  of the  success  or  failure  of  the  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

SMALL CAP COMPANY RISK involves the greater risk of investing in smaller,  less
well-known  companies  that may be more  vulnerable  than larger  companies  to
adverse business or economic developments.  Securities of such companies may be
less liquid and more volatile than securities of larger companies or the market
averages in general and, therefore,  may involve greater risk than investing in
larger companies. In addition, small cap companies may not be well-known to the
investing  public,  may not have  institutional  ownership,  and may have  only
cyclical, static, or moderate growth prospects.

Other risks of the Fund include the risks of foreign investing and investing in
real estate investment trusts (REITs).

FOREIGN INVESTING RISK involves the possibility that the Fund's  investments in
foreign  stock,  including  American  Depositary  Receipts  (ADRs)  and  Global
Depositary  Receipts  (GDRs),  will decrease  because of the  following  unique
risks: currency exchange rate fluctuations; foreign market illiquidity; control
regulations;   foreign  ownership  limits;   uncertain  political   conditions;
different accounting,  reporting, and disclosure requirements; and difficulties
in obtaining  legal  judgments.  In the past,  equity and debt  instruments  of
foreign  markets have been more  volatile than equity and debt  instruments  of
U.S. securities markets.

   *  EMERGING  MARKETS  RISK. A country  that is in the initial  stages of its
      industrial  cycle  is  considered  to be  an  emerging  markets  country.
      Investments  in  developing   countries   involve  exposure  to  economic
      structures  that are generally less diverse and mature than in the United
      States and to political  systems  which may be less stable.  In the past,
      markets of developing  countries have been more volatile than the markets
      of developed countries.

                                      14B
<PAGE>

   *  POLITICAL  RISK.  Political  risk includes a greater  potential for coups
      d'etat,  revolts,  and expropriation by governmental  organizations.  For
      example,  we may invest the  Fund's  assets in Eastern  Europe and former
      states of the Soviet Union (also known as the Commonwealth of Independent
      States or CIS).  These countries were under  communist  systems which had
      nationalized private industry. There is no guarantee that nationalization
      may not occur  again in this  region or others in which we may invest the
      Fund's  assets,  in which  case,  we may  lose all or part of the  Fund's
      investment in that country's issuers.

REITs.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  Additionally,  REITs are
dependent  upon  the  capabilities  of  the  REIT   manager(s),   have  limited
diversification, and could be significantly impacted by changes in tax laws.

WHO SHOULD CONSIDER INVESTING IN THIS FUND

This Fund is designed for the investor seeking to benefit from long-term growth
of capital.  Generally,  this Fund is expected to have a greater  potential for
long-term  capital  appreciation than the USAA Life Growth and Income Fund, but
is also significantly more volatile.

The bar chart  shown below illustrates the Fund's performance for the  one-year
period,  while the table shows the Fund's average annual total returns  for the
one-year   period  as  well  as  the  life of the  Fund.  Remember,  historical
performance does not necessarily  indicate what will happen in the future. Also
keep in  mind,  the  total  return  calculations  do not  include  other  costs
associated  with the annuity or life  insurance  policy;  and if they did,  the
Fund's performance would be lower.

USAA LIFE INTERNATIONAL FUND

OBJECTIVE

Capital appreciation with a secondary objective of current income.

PRINCIPAL INVESTMENT STRATEGY

The  Fund's  principal  investment  strategy  is to  invest at least 80% of the
Fund's  assets in  equity  securities  of  foreign  companies.  We use the term
"equity  securities"  to include common stocks,  preferred  stocks,  securities
convertible  into common  stocks,  and  securities  that carry the right to buy
common stocks.  A foreign  company is one organized under the laws of a foreign
country, and it must also have one of the following additional characteristics:

   *  the principal trading market for the stock is in a foreign country; or
   *  at least 50% of its  revenues  or profits  are  derived  from  operations
      within foreign countries; or
   *  at least 50% of its assets are located within foreign countries.

We may  invest  the  remainder  of the Fund's  assets in equity  securities  of
companies  that meet any of the criteria as described  in the  definition  of a
foreign company and in investment-grade, short-term debt instruments having the
following characteristics:

   *  remaining  maturities  of less than one year  that  have  been  issued or
      guaranteed as to both  principal  and interest by the U.S.  Government or
      its agencies or instrumentalities, or
   *  repurchase agreements collateralized by such securities.

There  are no  restrictions  as to the types of  businesses  or  operations  of
companies in which the Fund's  assets may be  invested,  except that we may not
invest more than 25% of the Fund's  total  assets in one  industry.  The Fund's
investments will be diversified in at least four or more countries.  We believe
the Fund combines the  advantages of  investment in  diversified  international
markets with the convenience and liquidity of a mutual fund based in the United
States.

In deciding which  securities to buy and sell, we review  countries and regions
for  economic and  political  stability  as well as future  prospects.  Then we
research  individual  companies  looking  for  favorable   valuations,   growth
prospects,  quality of management, and industry outlook. Securities are sold if
we  believe  they  are  overvalued  or if the  economic  or  political  outlook
significantly deteriorates.

As a temporary  defensive measure because of market,  economic,  political,  or
other  conditions,   we  may  invest  up  to  100%  of  the  Fund's  assets  in
investment-grade, short-term debt instruments. This  may result in the Fund not
achieving  its  investment  objective  during the time it is in this  temporary
defensive posture.

MAIN RISKS

The  primary  risks of  investing  in this Fund are market risk and the risk of
foreign investing.

MARKET RISK  involves the  possibility  that the Fund's  investments  in equity
securities  will  decline in a down  stock  market,  reducing  the value of the
company's  stock,  regardless  of the  success  or  failure  of  the  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

FOREIGN INVESTING RISK involves the possibility that the Fund's  investments in
foreign  stock,  including  American  Depositary  Receipts  (ADRs)  and  Global
Depositary  Receipts  (GDRs),  will decrease  because of the  following  unique
risks: currency exchange rate fluctuations; foreign market illiquidity; control
regulations;   foreign  ownership  limits;   uncertain  political   conditions;
different accounting,  reporting, and disclosure requirements; and difficulties
in obtaining  legal  judgments.  In the past,  equity and debt  instruments  of
foreign  markets have been more  volatile than equity and debt  instruments  of
U.S. securities markets.

   *  EMERGING  MARKETS  RISK. A country  that is in the initial  stages of its
      industrial  cycle  is  considered  to be  an  emerging  markets  country.
      Investments  in  developing   countries   involve  exposure  to  economic

      investment in that country's issuers.

                                      16B
<PAGE>

   *  EURO CONVERSION RISK. Beginning January 1, 1999, countries  participating
      in the European  Monetary Union began  converting their currencies into a
      new currency unit called the Euro. The conversion to the Euro, which will
      continue in stages  through  2002,  is expected to reshape the  financial
      markets, banking systems, and monetary policies in Europe and other parts
      of the world and could adversely  affect the Fund's  investments in these
      markets. In addition, a failure of the clearing and settlement systems in
      these markets to handle the Euro conversion  could  adversely  affect the
      Fund.

WHO SHOULD CONSIDER INVESTING IN THIS FUND

This Fund is designed for the investor seeking to benefit from greater exposure
to investments in foreign  securities that is generally  available  through the
USAA World  Growth  Fund.  Because of the Fund's  greater  emphasis  on foreign
securities,  the USAA Life  International  Fund can be  expected  to  present a
greater  level of risk than the USAA Life World  Growth  Fund and should not be
relied upon as a complete investment program.

FUND MANAGEMENT

The Trust has retained us, USAA Investment  Management Company, to serve as the
manager and  distributor  for the Trust. We are an affiliate of United Services
Automobile   Association  (USAA),  a  large,   diversified  financial  services
institution.  As of the  date  of this  Prospectus,  we had  approximately  $40
billion  in  total  assets  under  management.  Our  mailing  address  is  9800
Fredericksburg Road, San Antonio, TX 78288.

Although our officers and employees,  as well as those of the Trust, may engage
in personal securities transactions, they are restricted by the procedures in a
Joint Code of Ethics adopted by the Trust and us.

ADVISORY FEES

We provide management  services to the Funds pursuant to an Advisory Agreement.
We are responsible for managing the Funds' portfolios  (including  placement of
brokerage orders) and their business  affairs,  subject to the authority of and
supervision  by the Board of Trustees.  For our  services,  the Funds pay us an
annual fee. This fee, which is accrued daily and paid monthly, is computed as a
percentage of average net assets (ANA). For the Trust's most recent fiscal year
ended  December  31,  1998,  the fee for each Fund (other  than the  Aggressive
Growth Fund and the International Fund) was equal to an annualized rate of .20%
of the  monthly  ANA.  With  respect  to the  Aggressive  Growth  Fund  and the
International  Fund, we received  fees equal to an annualized  rate of .50% and
 .65%,  respectively,  of each  Fund's  monthly  ANA. We also  provide  services
related to selling  the Funds'  shares and  receive no  compensation  for those
services.

PURCHASE OF FUND SHARES

The Trust currently sells shares of the Funds in a continuous  offering only to
separate  accounts funding benefits to variable annuity  contracts and variable
life insurance  policies issued by USAA Life Insurance  Company.  Each separate
account is divided into fund accounts, seven of which invest in a corresponding
Fund of the Trust, as directed by contract and policy owners. The fund accounts
that purchase  Trust shares do so at the net asset value per share (NAV) of the
corresponding  Funds,  without a sales charge,  next determined after USAA Life
Insurance  Company  receives  instructions to invest from you or other contract
and policy owners (such as making a premium  payment) or after the operation of
a contract or policy (such as deduction of fees and charges).

Investments in each Fund are credited to each corresponding Fund Account in the
form of full and  fractional  shares of the  designated  Fund. The Funds do not
issue share  certificates.  Initial and  subsequent  minimum  premium  payments
allocated to one or more specific Funds are in the prospectuses of the variable
annuity contract and variable life insurance policies.

REDEMPTION OF FUND SHARES

The fund accounts redeem shares of the  appropriate  Fund based on instructions
by you or other  contract  and policy  owners to receive  back  monies  under a
contract  (such as  surrendering  a contract),  or the  operation of a contract
(such as deduction of fees and  charges).  Fund  accounts may redeem any of the
Fund's  shares  on any day the NAV per  share is  calculated.  Redemptions  are
effective on the day  instructions are received.  However,  if instructions are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day.

The Fund will make  payment for  redeemed  shares  within  seven days after the
effective date of redemption.  The amount  received upon redemption may be more
or less than the amount paid for the shares, depending upon the fluctuations in
the market value of the assets owned by a particular Fund.

In  addition,  the Trust  may  elect to  suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

The price at which Fund shares are purchased and redeemed by separate  accounts
is equal to the net asset value  (NAV) per share  determined  on the  effective
date of the purchase or redemption.  Separate accounts buy and sell Fund shares
at the NAV per  share  without  a sales  charge.  The  Fund's  NAV per share is
calculated at the close of the regular  trading  session of the NYSE,  which is
usually 4:00 p.m. Eastern Time.

VALUATION OF FUND SECURITIES FOR EACH FUND 
(EXCEPT THE USAA LIFE MONEY MARKET FUND)

Portfolio  securities,  except  as  otherwise  noted,  traded  primarily  on  a
securities  exchange  are  valued  at the last  sales  price on that  exchange.
Portfolio  securities  traded  primarily on foreign  securities  exchanges  are
generally valued at the closing values of such securities on the exchange where
primarily  traded.  If no sale is  reported,  the  average of the bid and asked
prices is generally used.

Securities  trading in various  foreign markets may take place on days when the
NYSE is closed.  Further,  when the NYSE is open,  the  foreign  markets may be
closed.  Therefore, the calculation of the Fund's NAV may not take place at the
same time the prices of certain securities held by the Fund are determined.  In
most cases,  events  affecting  the values of portfolio  securities  that occur
between the time their prices are determined and the close of normal trading on
the NYSE on a day the Fund's NAV is  calculated  will not be  

                                      18B
<PAGE>

reflected in the Fund's NAV. If, however,  we determine that a particular event
would materially affect the Fund's NAV, then we, under the general  supervision
of the Board of  Trustees,  will use all  relevant,  available  information  to
determine a fair value for the affected portfolio securities.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Board of Trustees.  Securities that cannot be
valued by these methods, and all other assets, are valued in good faith at fair
value using methods we have  determined  under the general  supervision  of the
Board of Trustees.

VALUATION OF THE USAA LIFE MONEY MARKET FUND SECURITIES

Securities are stated at amortized cost, which  approximates  market value. For
additional   information  on  how  securities  are  valued,  see  VALUATION  OF
SECURITIES in the Trust's Statement of Additional Information.

DIVIDENDS AND DISTRIBUTIONS

Each Fund (except the USAA Life Money Market Fund) pays net  investment  income
dividends to separate accounts as shareholders at least once each year. Any net
capital gains  generally will be distributed at least  annually.  The Fund will
make additional payments, if necessary,  to avoid the imposition of any federal
income or excise tax.

With  respect to the USAA Life Money  Market  Fund,  net  investment  income is
accrued daily and paid on the last business day of the month.  Daily  dividends
are declared at the time the NAV per share is calculated. Dividends shall begin
accruing on shares  purchased the day  following  the effective  date and shall
continue to accrue to the effective date of redemption.

All income dividends and capital gain distributions will be paid in the form of
additional  shares of that Fund at the NAV per share.  The share  price will be
the NAV of the Funds'  shares  computed  on the  ex-dividend  date.  Any income
dividends or capital gain  distributions  paid by the Funds will reduce the NAV
per share by the amount of the dividend or distribution.

TAXES

As mutual funds, the Funds themselves will not be subject to federal income tax
provided  they  distribute  all of their income and net capital  gains for each
taxable year in accordance  with the Internal  Revenue Code.  Because the Funds
sell shares  only to separate  accounts  funding  benefits to variable  annuity
contracts  and  variable  life  insurance   policies,   Internal  Revenue  Code
provisions  applicable  to separate  accounts of  variable  insurance  products
apply. As such, you should refer to the accompanying  prospectus that describes
the variable annuity contract or variable life insurance policy, as applicable,
for  the  federal   income  tax   treatment  of  the  contract  or  policy  and
distributions  to you as a contract or policy owner and for the consequences of
the Trust's failure to meet Internal Revenue Code requirements.

YEAR 2000

Like  other  organizations  around  the  world,  the Funds  could be  adversely
affected if the computer systems used by the Funds, their service providers, or
companies  in which the Funds  invest do not  properly  process  and  calculate
information  that relates to dates  beginning  on January 1, 2000,  and beyond.
This situation may occur because for many years computer  programmers used only
two digits to describe  years,  such as 98 for 1998. A program  written in this
manner may not work when it encounters  the year 00. The Trust has been advised
by USAA Life and us that to confront this situation,  USAA companies have spent
much effort and money;  and they expect to have our systems  ready for the Year
2000 by  mid-1999.  In  addition,  we are  actively  assessing  the  Year  2000
readiness of the Trust's service  providers,  partners,  and companies in whose
securities  the Funds invest.  It is not possible for the Trust to say that you
will experience no effect from this  situation,  but the Trust has been advised
that USAA  companies  are making a large  effort to avoid any ill effects  upon
contract and policy owners.

FINANCIAL HIGHLIGHTS

The financial highlights tables are intended to help you understand each Fund's
financial  performance since inception.  Certain information reflects financial
results from a single Fund share.  The total return in the table represents the
rate that an investor  would have earned (or lost) on an investment in the Fund
(assuming  reinvestment of all dividends and  distributions).  This information
has been audited by KPMG LLP,  whose report,  along with each Fund's  financial
statements, are included in the Annual Report, which is available upon request.

(a)  Calculated using weighted average shares.
(b)  The total return of a Fund refers to the  percentage  change in value of a
     hypothetical  investment,  including the deduction of a proportional share
     of fund  expenses,  and assumes all income and capital gain  distributions
     are reinvested. Total returns from the period do not reflect expenses that
     apply at the Separate  Account level  including risk and expense  charges.
     These expenses would reduce the total return for the period shown.
(c)  Annualized.  The  ratio is not  necessarily  indicative  of 12  months  of
     operations.

                                   APPENDIX A

THE FOLLOWING ARE  DESCRIPTIONS  OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST ONE OR MORE FUNDS' ASSETS:

AMERICAN DEPOSITARY RECEIPTS (ADRs)

We may invest the USAA Life World Growth,  USAA Life  International,  USAA Life
Growth and Income,  and USAA Life Aggressive Growth Funds assets in ADRs, which
are  foreign  shares  held by a U.S.  bank  that  issues a  receipt  evidencing
ownership. Dividends are paid in U.S. dollars.

CONVERTIBLE SECURITIES

We may invest each Fund's  assets,  except the USAA Life Money Market Fund,  in
convertible securities, which are bonds, preferred stocks, and other securities
that pay interest or  dividends  and offer the buyer the ability to convert the
security  into  common  stock.  The  value of  convertible  securities  depends
partially  on  interest  rate  changes  and the credit  quality of the  issuer.
Because a convertible security affords an investor the opportunity, through its
conversion  feature,  to  participate  in  the  capital   appreciation  of  the
underlying  common stock,  the value of convertible  securities also depends on
the price of the underlying common stock.

EURODOLLAR AND YANKEE OBLIGATIONS

We may  invest a portion  of each  Fund's  assets  (except  the USAA Life World
Growth,  USAA Life  International,  and USAA Life  Aggressive  Growth Funds) in
dollar-denominated  instruments  that have been issued outside the U.S. capital
markets by  foreign  corporations  and  financial  institutions  and by foreign
branches of U.S. corporations and financial  institutions  (Eurodollar) as well
as  dollar-denominated  instruments that have been issued by foreign issuers in
the U.S. capital markets (Yankee).  In addition, we may invest a portion of the
Funds' assets in Eurodollar and Yankee obligations of investment-grade emerging
market countries.

FORWARD CURRENCY CONTRACTS

The USAA Life World Growth, USAA Life  International,  and USAA Life Aggressive
Growth Funds may enter into forward currency contracts, which means we may hold
securities  denominated in foreign  currencies.  As a result,  the value of the
securities  will be affected by changes in the exchange rate between the dollar
and  foreign  currencies.  In  managing  currency  exposure,  we may enter into
forward currency  contracts.  A forward currency contract involves an agreement
to purchase or sell a specified  currency at a specified  future date or over a
specified time period at a price set at the time of the contract. We only enter
into forward  currency  contracts  when the Fund enters into a contract for the
purchase or sale of a security  denominated in foreign  currency and desires to
lock in the U.S. dollar price of that security.

GLOBAL DEPOSITARY RECEIPTS (GDRs)

We may invest the USAA Life World  Growth,  USAA Life  International,  and USAA
Life Aggressive  Growth Funds' assets in GDRs, which are foreign shares held by
a U.S. or foreign bank that issues a receipt  evidencing  ownership.  Dividends
are paid in U.S. dollars.

ILLIQUID SECURITIES

We may  invest up to 15% of each  Fund's  net  assets and up to 10% of the USAA
Life Money Market Fund's net assets in securities  that are illiquid.  Illiquid
securities  are those  securities  which  cannot be disposed of in the ordinary
course of business, seven days or less, at approximately the value at which the
Fund has valued the securities.

MASTER DEMAND NOTES

We may invest each Fund's assets (except the USAA Life World Growth,  USAA Life
International,  and USAA Life Aggressive  Growth Funds) in master demand notes,
which are obligations that permit the investment of fluctuating  amounts by the
Fund, at varying rates of interest using direct arrangements  between the Fund,
as lender,  and the  borrower.  These notes permit daily changes in the amounts
borrowed.  The Fund has the right to increase  the amount under the note at any
time up to the full amount provided by the note  agreement,  or to decrease the
amount,  and the  borrower  may repay up to the full amount of the note without
penalty. Frequently, such obligations are secured by letters of credit or other
credit support arrangements  provided by banks. Because master demand notes are
direct lending arrangements between the lender and borrower,  these instruments
generally will not be traded,  and there  generally is no secondary  market for
these notes,  although they are redeemable  (and  immediately  repayable by the
borrower) at face value, plus accrued interest, at any time. We will invest the
Funds'  assets in master  demand  notes  only if the Board of  Trustees  or its
delegate has determined that they are of credit quality  comparable to the debt
securities in which the Fund generally may invest.

MONEY MARKET INSTRUMENTS

We may hold a certain portion of each Fund's assets in  investment-grade,  U.S.
dollar-denominated  debt securities that have remaining  maturities of one year
or less. Such securities may include U.S.  Government  obligations,  commercial
paper  and  other  short-term  corporate  obligations,   repurchase  agreements
collateralized  with  U.S.  Government  securities,  certificates  of  deposit,
bankers  acceptances,  and  other  financial  institution  obligations.   These
securities may carry fixed or variable interest rates.

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES

We may invest each Fund's assets (except the USAA Life World Growth,  USAA Life
International,  and USAA Life Aggressive Growth Funds) in  mortgage-backed  and
asset-backed  securities.  Mortgage-backed  securities  include,  but  are  not
limited to, securities issued by the Government  National Mortgage  Association
(Ginnie Mae), the Federal National  Mortgage  Association  (Fannie Mae) and the
Federal Home Loan Mortgage Corporation (Freddie Mac).

                                      24B

These securities  represent  ownership in a pool of mortgage loans. They differ
from  conventional  bonds in that  principal  is paid back to the  investor  as
payments are made on the  underlying  mortgages in the pool.  Accordingly,  the
Fund receives monthly  scheduled  payments of principal and interest along with
any  unscheduled  principal  prepayments on the underlying  mortgages.  Because
these  scheduled  and  unscheduled  principal  payments  must be  reinvested at
prevailing  interest  rates,  mortgage-backed  securities  do  not  provide  an
effective means of locking in long-term  interest rates for the investor.  Like
other  fixed  income  securities,  when  interest  rates  rise,  the value of a
mortgage-backed  security generally will decline;  however, when interest rates
are declining, the value of mortgage-backed securities with prepayment features
may not increase as much as other fixed income securities.

Mortgage-backed  securities also include  collateralized  mortgage  obligations
(CMOs).  CMOs are obligations fully  collateralized by a portfolio of mortgages
or  mortgage-related  securities.  CMOs are divided into pieces (tranches) with
varying maturities.  The cash flow from the underlying mortgages is used to pay
off each tranche  separately.  CMOs are designed to provide investors with more
predictable maturities than regular mortgage securities but such maturities can
be  difficult  to  predict  because of the  effect of  prepayments.  Failure to
accurately predict  prepayments can adversely affect the Funds' return on these
investments. CMOs may also be less marketable than other securities.

Asset-backed  securities  represent a  participation  in, or are secured by and
payable  from, a stream of payments  generated by  particular  assets,  such as
credit card,  motor vehicle,  or trade  receivables.  They may be  pass-through
certificates,  which  have  characteristics  very  similar  to  mortgage-backed
securities,  discussed  above.  They may  also be in the  form of  asset-backed
commercial paper, which is issued by a special purpose entity, organized solely
to issue the  commercial  paper and to purchase  interests  in the assets.  The
credit quality of these  securities  depends  primarily upon the quality of the
underlying assets and the level of credit support and enhancement provided.

The weighted  average  life of such  securities  is likely to be  substantially
shorter  than their stated  final  maturity as a result of scheduled  principal
payments and unscheduled principal prepayments.

MUNICIPAL LEASE OBLIGATIONS

We may  invest  the USAA Life Money  Market  and USAA Life  Diversified  Assets
Funds'  assets in a variety  of  instruments  referred  to as  municipal  lease
obligations, including:

*  Leases,
*  Installment purchase contracts, and
*  Certificates of participation in such leases and contracts.

PUT BONDS

We may invest each  Fund's  assets in  securities  (including  securities  with
variable  interest rates) that may be redeemed or sold back (put) to the issuer
of the security or a third party prior to stated  maturity  (put  bonds).  Such
securities  will  normally  trade as if maturity is the earlier put date,  even
though stated maturity is longer.

REPURCHASE AGREEMENTS

We  may  invest  each  Fund's   assets  in  repurchase   agreements   that  are
collateralized  by  obligations  issued or guaranteed as to both  principal and
interest  by  the  U.S.  Government,  its  agencies  and  instrumentalities.  A
repurchase  agreement is a transaction  in which a security is purchased with a
simultaneous  commitment  to sell it back to the seller (a  commercial  bank or
recognized  securities  dealer) at an agreed upon price on an agreed upon date.
This date is usually  not more than seven days from the date of  purchase.  The
resale price  reflects  the  purchase  price plus an agreed upon market rate of
interest,  which is unrelated  to the coupon rate or maturity of the  purchased
security.

VARIABLE RATE SECURITIES

We may invest  each Fund's  assets in  securities  that bear  interest at rates
which are adjusted periodically to market rates.

*  These  interest  rate  adjustments  can both  raise  and  lower  the  income
   generated by such securities. These changes will have the same effect on the
   income earned by the Fund  depending on the  proportion  of such  securities
   held.

*  The value of variable rate  securities  is less  affected than  fixed-coupon
   securities by changes in prevailing  interest  rates because of the periodic
   adjustment of their coupons to a market rate. The shorter the period between
   adjustments,  the smaller the impact of interest  rate  fluctuations  on the
   value of these securities.

*  The market value of a variable rate security  usually tends toward par (100%
   of face value) at interest rate adjustment time.

WHEN-ISSUED SECURITIES

We may invest each Fund's assets in new issues of debt securities  offered on a
when-issued basis.

*  Delivery  and  payment  take  place  after  the  date of the  commitment  to
   purchase, normally within 45 days. Both price and interest rate are fixed at
   the time of commitment.

*  The Fund does not earn interest on the securities until settlement,  and the
   market  value  of  the  securities  may  fluctuate   between   purchase  and
   settlement.

*  Such securities can be sold before settlement date.

                        GENERAL INFORMATION AND HISTORY

     USAA  Life  Investment  Trust  (the  "Trust")  is a  diversified  open-end
management  investment  company  formed as a business  trust  under laws of the
state of  Delaware on July 20,  1994.  The Trust was  established  by USAA Life
Insurance  Company  ("USAA Life" or the  "Company")  to serve as an  investment
vehicle for premium payments  received by the Company from the sale of variable
annuity contracts (the "Contracts") funded through the Separate Account of USAA
Life Insurance  Company (the "Separate  Account").  The Trust also serves as an
investment  vehicle for premium payments  received by the Company from the sale
of variable life insurance  policies (the  "Policies")  funded through the Life
Insurance  Separate Account of USAA Life Insurance Company (the "Life Insurance
Separate  Account").  The Trust is currently made up of seven investment Funds:
USAA Life Money Market Fund (the "Money  Market  Fund"),  USAA Life Income Fund
(the "Income  Fund"),  USAA Life Growth and Income Fund (the "Growth and Income
Fund"),  USAA Life World  Growth  Fund (the  "World  Growth  Fund"),  USAA Life
Diversified Assets Fund (the "Diversified  Assets Fund"),  USAA Life Aggressive
Growth Fund (the "Aggressive  Growth Fund"),  and USAA Life  International Fund
(the  "International  Fund"),  collectively  referred to herein as the "Funds."
Each Fund represents a separate series of shares of beneficial  interest in the
Trust.  Each share of beneficial  interest issued with respect to an individual
Fund  represents  a  pro-rata  interest  in the  assets of that Fund and has no
interest in the assets of any other Fund. Each Fund bears its own liability and
also its proportionate share of the general liabilities of the Trust. The Trust
is registered under the Investment Company Act of 1940 (the "1940 Act") and its
shares are registered  under the Securities Act of 1933 (the "1933 Act").  This
registration  does not imply any  supervision  by the  Securities  and Exchange
Commission (the "SEC" or the "Commission")  over the Trust's  management or its
investment policies or practices.

     In the future,  the Trust may offer its shares to other separate  accounts
of USAA Life as well as unaffiliated life insurance  companies to fund benefits
under  variable  annuity  contracts  (contracts)  and variable  life  insurance
policies (policies).  The Trust does not foresee any disadvantage to purchasers
of  variable  contracts  and  policies  arising  out  of  these   arrangements.
Nevertheless,  differences  in treatment  under tax and other laws,  as well as
other  considerations,  could  cause the  interest  of  various  purchasers  of
contracts and policies to conflict.  For example,  violation of the federal tax
laws by one separate  account  investing in the Trust 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 the Trust.  If it becomes  necessary for any
separate  account to replace shares of the Trust with another  investment,  the
Trust may have to liquidate portfolio securities on a disadvantageous basis. At
the same time,  USAA IMCO and the Trust are  subject to  conditions  imposed by
the  SEC  designed  to  prevent  or  remedy  any  conflict of interest. In this
connection, the Board of Trustees has the obligation to monitor events in order
to  identify any material,  irreconcilable  conflicts  that may possibly  arise
and  to  determine  what action, if any, should be taken to remedy or eliminate
the conflict.

                                 LEGAL MATTERS

     Freedman, Levy, Kroll and Simonds,  Washington,  D.C., has passed upon the
legal  validity  of the  Funds'  shares  and has  advised  the Trust on certain
federal securities law matters.

                            VALUATION OF SECURITIES

     Shares of each Fund are  offered  on a  continuing  basis to the  Separate
Account and the Life Insurance Separate Account through USAA IMCO. The offering
price for  shares of each Fund is equal to the  current  net asset  value  (the
"NAV") per share.  The NAV per share of each Fund is  calculated  by adding the
value of each of the Fund's  portfolio  securities and other assets,  deducting
its  liabilities,  and  dividing  the  remainder  by the number of Fund  shares
outstanding.

     A Fund's NAV per share is  calculated  each day,  Monday  through  Friday,
except days on which the New York Stock  Exchange (the  "Exchange")  is closed.
The  Exchange is  currently  scheduled  to be closed on New Year's Day,  Martin
Luther King Jr. Day, President's Day, Good Friday,  Memorial Day,  Independence
Day, Labor Day, Thanksgiving Day, and Christmas, and on the preceding Friday or
subsequent  Monday  when one of these  holidays  falls on a Saturday or Sunday,
respectively.

     The value of the  securities  of each Fund,  other  than the Money  Market
Fund, is determined by one or more of the following methods:

 (1)   Portfolio  securities,  except as otherwise noted, traded primarily on a
       domestic securities exchange, are valued at the last sales price on that
       exchange. If no sale is reported, the average of the bid price and asked
       prices is generally used depending upon local custom or regulation.

 (2)   Securities traded in a U.S.  over-the-counter  ("OTC") market are priced
       at the last sales price or, if not available,  at the average of the bid
       and asked prices at the time regular trading of listed securities closes
       on the Exchange.

 (3)   Debt securities  purchased with maturities of 60 days or less are stated
       at amortized cost, which generally approximates market value. Repurchase
       agreements are valued at cost.

 (4)   Other debt  securities are valued each business day by a pricing service
       (the  "Service")  approved  by the Board of  Trustees  of the Trust (the
       "Board of  Trustees").  The Service uses the mean between quoted bid and
       asked prices,  or the last sales price, to price securities when, in the
       Service's   judgment,   these  prices  are  readily  available  and  are
       representative  of the securities'  market values.  For many securities,
       such prices are not readily  available.  The  Service  generally  prices
       those securities based on methods which include  consideration of yields
       or prices of  securities  of comparable  quality,  coupon,  maturity and
       type,  indicators as to values from dealing in  securities,  and general
       market conditions.

 (5)   Securities   primarily  traded  on  foreign  securities   exchanges  are
       generally valued at the preceding  closing value of such security on the
       exchange  where  they  are  primarily  traded.  If no  closing  price is
       available,  the average of the bid price and asked  prices is  generally
       used, depending upon local custom or regulation.

 (6)   All foreign  securities  traded in the OTC market are valued at the last
       sales price,  or, if not available,  at the average of the bid and asked
       prices.  If there is not active  trading in a particular  security for a
       given day,  the average of the bid price and asked  prices is  generally
       used.

 (7)   Securities that cannot be valued by the methods set forth above, and all
       other  assets,  are  valued in good  faith at fair  market  value  using
       methods  determined by the Adviser under the general  supervision of the
       Board of  Trustees.  For purposes of  determining  each Fund's net asset
       value,  all  assets  and  liabilities  initially  expressed  in  foreign
       currency  values will be converted  into U.S.  dollar values at the spot
       price of such  currencies  against  U.S.  dollars as last  quoted by any
       recognized broker-dealer.

                                       3
<PAGE>

     The value of the Money  Market  Fund's  securities  is stated at amortized
cost,  which  generally  approximates  market value.  This  involves  valuing a
security  at its  cost and  thereafter  assuming  a  constant  amortization  to
maturity of any discount or premium,  regardless  of the impact of  fluctuating
interest  rates.  While this method  provides  certainty in  valuation,  it may
result in periods  during which the value of an  instrument,  as  determined by
amortized  cost,  is higher or lower than the price the Fund would receive upon
the sale of the instrument.

     The valuation of the Money Market Fund's portfolio  instruments based upon
their amortized cost is subject to the Fund's  adherence to certain  procedures
and conditions.  The Adviser will purchase U.S.  dollar-denominated  securities
with   remaining   maturities   of  397  days  or  less  and  will  maintain  a
dollar-weighted average portfolio maturity of no more than 90 days. The Adviser
will invest only in securities  that are judged to present  minimal credit risk
and that satisfy the quality and  diversification  requirements  of  applicable
rules and regulations of the SEC.

     The Board of Trustees has established procedures designed to stabilize the
Money Market  Fund's price per share,  as computed for the purpose of sales and
redemptions,  at $1. There can be no assurance,  however, that the Fund will at
all times be able to  maintain a constant  $1 NAV per  share.  Such  procedures
include  review  of  the  Fund's  holdings  at  such  intervals  as  is  deemed
appropriate to determine whether the Fund's NAV,  calculated by using available
market  quotations,  deviates  from  $1 per  share  and,  if so,  whether  such
deviation may result in material  dilution,  or is otherwise unfair to existing
shareholders.  In the event that it is determined that such a deviation exists,
the Board of  Trustees  will  take such  corrective  action  as it  regards  as
necessary  and   appropriate.   Such  action  may  include  selling   portfolio
instruments  prior to maturity to realize capital gains or losses or to shorten
average portfolio maturity,  withholding dividends,  or establishing an NAV per
share by using available market quotations.

             ADDITIONAL INFORMATION REGARDING REDEMPTION OF SHARES

     The Trust reserves the right to suspend the redemption of Trust shares (1)
for any periods  during which the  Exchange is closed,  (2) when trading in the
markets the Trust normally  utilizes is restricted,  or an emergency  exists as
determined  by  the  SEC  so  that  disposal  of  the  Trust's  investments  or
determination of its NAV is not reasonably  practicable,  or (3) for such other
periods  as the  SEC  by  order  may  permit  for  protection  of  the  Trust's
shareholders.

                       INVESTMENT POLICIES AND TECHNIQUES

     The Prospectus  describes certain  fundamental  investment  objectives and
certain investment  policies applicable to each Fund. The following is provided
as additional  information.  Each Fund's objective(s) cannot be changed without
shareholder approval.

SECTION 4(2) COMMERCIAL PAPER AND RULE 144A SECURITIES

     The Funds may  invest  in  commercial  paper  issued  in  reliance  on the
"private placement" exemption from registration afforded by Section 4(2) of the
1933 Act ("Section 4(2) Commercial  Paper").  Section 4(2) Commercial  Paper is
restricted as to disposition under the federal securities laws; therefore,  any
resale of Section  4(2)  Commercial  Paper must be  effected  in a  transaction
exempt from registration under the Securities Act of 1933 ("1933 Act"). Section
4(2) Commercial Paper is normally resold to other investors through or with the
assistance  of the issuer or  investment  dealers  who make a market in Section
4(2) Commercial Paper, thus providing liquidity.

     The Funds may also purchase  restricted  securities eligible for resale to
"qualified  institutional  buyers"  pursuant  to Rule  144A  under the 1933 Act
("Rule 144A  Securities").  Rule 144A provides a non-exclusive safe harbor from
the registration requirements of the 1933 Act for resales of certain securities
to institutional investors.

     Certain  foreign  securities  (including  Eurodollar  obligations)  may be
eligible  for resale  pursuant  to Rule 144A in the United  States and may also
trade without  restriction in one or more foreign markets.  Such securities may
be determined to be liquid based upon these foreign  markets  without regard to
their  eligibility  for resale  pursuant  to Rule 144A.  In such  cases,  these
securities  will not be treated as Rule 144A  Securities  for  purposes  of the
liquidity guidelines established by the Board of Trustees.

LIQUIDITY DETERMINATIONS

     The  Board  of  Trustees  has  established  guidelines  pursuant  to which
municipal  lease   obligations,   Section  4(2)  Commercial  Paper,  Rule  144A
Securities,  and  certain  restricted  debt  securities  that  are  subject  to
unconditional  put or demand  features  exercisable  within seven days ("Demand
Feature  Securities")  may be determined to be liquid for purposes of complying
with a Fund's  investment  restriction  applicable to  investments  in illiquid
securities.  In  determining  the  liquidity  of municipal  lease  obligations,
Section 4(2)  Commercial  Paper,  and Rule 144A  Securities,  the Adviser will,
among other things,  consider the following factors established by the Board of
Trustees: (1) the frequency of trades and quotes for the

                                       4
<PAGE>

security,  (2) the number of dealers  willing to purchase or sell the  security
and the number of other potential purchasers, (3) the willingness of dealers to
undertake to make a market in the security,  and (4) the nature of the security
and the nature of the marketplace trades,  including the time needed to dispose
of the  security,  the  method  of  soliciting  offers,  and the  mechanics  of
transfer.  Additional  factors  considered  by the Adviser in  determining  the
liquidity of a municipal lease obligation are: (1) whether the lease obligation
is of a size that will be attractive to  institutional  investors,  (2) whether
the lease  obligation  contains a  non-appropriation  clause and the likelihood
that the  obligor  will fail to make an  appropriation  therefor,  and (3) such
other   factors  as  the  Adviser  may   determine   to  be  relevant  to  such
determination.  In determining the liquidity of Demand Feature Securities,  the
Adviser  will  evaluate  the credit  quality of the party (the "Put  Provider")
issuing (or unconditionally  guaranteeing performance on) the unconditional put
or demand  feature of the Demand Feature  Securities.  In evaluating the credit
quality of the Put  Provider,  the Adviser  will  consider  all factors that it
deems  indicative  of the capacity of the Put Provider to meet its  obligations
under the Demand Feature  Securities  based upon a review of the Put Provider's
outstanding debt and financial statements and general economic conditions.

LENDING OF SECURITIES

     Each Fund may lend its  securities.  A lending policy may be authorized by
the Board of Trustees and  implemented  by the Adviser,  but  securities may be
loaned only to qualified  broker-dealers or institutional  investors that agree
to maintain cash collateral  with the Trust's  custodian or another third party
custodian  equal  at all  times  to at least  100% of the  value of the  loaned
securities.  The Board of Trustees will  establish  procedures  and monitor the
creditworthiness  of any institution or broker-dealer  during such times as any
loan is outstanding.  The Trust will continue to receive interest on the loaned
securities and will invest the cash collateral in short-term obligations of the
U.S.  Government  or of its  agencies  or  instrumentalities  or in  repurchase
agreements, thereby earning additional interest.

     No loan of securities will be made if, as a result,  the aggregate of such
loans would exceed 33 1/3% of the value of a Fund's total  assets,  except that
this limitation does not apply to purchases of debt securities or to repurchase
agreements. The Trust may terminate such loans at any time.

FORWARD CURRENCY CONTRACTS

     The World Growth Fund,  Aggressive Growth Fund, and the International Fund
may  enter  into  forward  currency  contracts  in  order  to  protect  against
uncertainty in the level of future foreign exchange rates.

     A forward currency contract is an agreement to purchase or sell a specific
currency at a specified time period at a price set at the time of the contract.
These contracts are usually traded directly  between  currency traders (usually
large commercial banks) and their customers.  A forward contract  generally has
no deposit requirements, and no commissions are charged.

     Although  the Fund  values its assets each  business  day in terms of U.S.
dollars, it does not intend to convert its foreign currencies into U.S. dollars
on a daily  basis.  It will do so from  time to time,  and may  incur  currency
conversion  costs.  Although  foreign  exchange dealers do not charge a fee for
conversion,  they do realize a profit based on the difference  (spread) between
the prices at which they are buying and selling  various  currencies.  Thus,  a
dealer may offer to sell that currency to the Fund at one rate,  while offering
a lesser rate of exchange should the Fund desire to resell that currency to the
dealer.

WHEN-ISSUED SECURITIES

     Each  Fund may  invest  in new  issues  of debt  securities  offered  on a
when-issued  basis;  that is,  delivery of and payment for the securities  take
place after the date of the  commitment to purchase,  normally  within 45 days.
The  payment  obligation  and the  interest  rate that will be  received on the
securities are each fixed at the time the buyer enters into the  commitment.  A
Fund may sell  these  securities  before  the  settlement  date if it is deemed
advisable.

     Cash or  high-quality,  liquid debt securities  equal to the amount of the
when-issued  commitments  are  segregated  at the Fund's  custodian  bank.  The
segregated  securities are valued at market, and daily deposit  adjustments are
made to keep the value of the cash and segregated  securities at least equal to
the  amount of such  commitments  by the Fund.  On the  settlement  date of the
when-issued securities,  the Fund will meet its obligations from then available
cash, sale of segregated securities, sale of other securities, or from the sale
of the  when-issued  securities  themselves  (which may have a value greater or
less than the Fund's payment obligations).

REAL ESTATE INVESTMENT TRUSTS (REITS)

     Because  each Fund  (other than the Money  Market  Fund and  International
Fund) may invest a portion of its assets in equity  securities  of REITs,  each
Fund may also be subject to certain risks associated with direct investments in
REITs.  In addition,  the Income Fund,  Growth and Income Fund, and Diversified
Assets  Fund may  invest  their  assets  in the debt  securities  of REITs  and
therefore,  may be  subject  to  certain  other  risks,  such as  credit  risk,
associated  with  investment  in the debt  securities  of  REITs.  REITs may be
affected by changes in the value of their underlying properties and by defaults
by borrowers or tenants.  Furthermore,  REITs are  dependent  upon  specialized
management skills of their managers and may

                                       5
<PAGE>

have limited  geographic  diversification,  thereby,  subjecting  them to risks
inherent in financing a limited number of projects.  REITs depend  generally on
their ability to generate cash flow to make distributions to shareholders,  and
certain REITs have  self-liquidation  provisions by which mortgages held may be
paid in full and distributions of capital returns may be made at any time.

REPURCHASE AGREEMENTS

     Each Fund may invest in repurchase  agreements that are  collateralized by
obligations  issued or guaranteed as to both principal and interest by the U.S.
Government,  its agencies or  instrumentalities.  A  repurchase  agreement is a
transaction in which a security is purchased with a simultaneous  commitment to
sell it back to the seller (a commercial bank or recognized  securities dealer)
at an agreed upon price on an agreed  upon date.  This date is usually not more
than  seven  days from the date of  purchase.  The resale  price  reflects  the
purchase price plus an agreed upon market rate of interest,  which is unrelated
to the coupon rate or maturity of the purchased security. The obligation of the
seller to pay the agreed  upon  price is in effect  secured by the value of the
underlying security. In these transactions,  the securities purchased by a Fund
will have a total value  equal to or in excess of the amount of the  repurchase
obligation and will be held by the Fund's custodian until  repurchased.  If the
seller defaults and the value of the underlying security declines, the Fund may
incur a loss and may incur  expenses in selling the  collateral.  If the seller
seeks relief under the bankruptcy  laws, the  disposition of the collateral may
be delayed or limited.

TEMPORARY DEFENSIVE POLICY

     Each Fund may on a temporary basis because of market, economic, political,
or other  conditions,  invest  up to 100% of its  assets  in  investment-grade,
short-term debt instruments.  Such securities may consist of obligations of the
U.S. Government,  its agencies or instrumentalities,  and repurchase agreements
secured by such  instruments;  certificates of deposit of domestic banks having
capital,  surplus,  and undivided  profits in excess of $100 million;  banker's
acceptances  of  similar  banks;  commercial  paper  and other  corporate  debt
obligations.

                            INVESTMENT RESTRICTIONS

     The following  investment  restrictions have been adopted by the Trust for
and  are  applicable  to  each  Fund  as  stated.  They  are  considered  to be
fundamental  policies  of the Funds,  and may not be changed for any given Fund
without  approval  by the  lesser of (1) 67% or more of the  voting  securities
present  at a meeting  of the Fund if more than 50% of the  outstanding  voting
securities of the Fund are present or represented by proxy or (2) more than 50%
of the Fund's outstanding voting securities. The investment restrictions of one
Fund may be changed without affecting those of any other Fund.

     Under the restrictions, each Fund may not:

 (1)   Issue  senior   securities,   except  for  borrowings   described  under
       restriction (6) and as permitted under the 1940 Act;

 (2)   Underwrite securities of other issuers, except to the extent that it may
       be deemed to act as a statutory  underwriter in the  distribution of any
       restricted securities or not readily marketable securities;

 (3)   Purchase or sell real estate unless acquired as a result of ownership of
       securities or other instruments (but this shall not prevent  investments
       in securities secured by real estate or interests therein);

 (4)   Lend any securities or make any loan if, as a result,  more than 33 1/3%
       of its total  assets  would be lent to other  parties,  except that this
       limitation  does  not  apply  to  purchases  of  debt  securities  or to
       repurchase agreements; or

 (5) Purchase or sell commodities or commodities contracts.

 (6)   Borrow  money,  except  that a Fund may borrow  money for  temporary  or
       emergency  purposes  in an  amount  not  exceeding  33 1/3% of its total
       assets  (including  the amount  borrowed) less  liabilities  (other than
       borrowings).  A Fund will not purchase  securities  when its  borrowings
       exceed 5% of its total assets.

 (7)   With respect to 75% of its total assets,  purchase the securities of any
       issuer  (except  Government  Securities,  as such term is defined in the
       1940  act) if,  as a  result,  the Fund  would  own more than 10% of the
       outstanding voting securities of such issuer or the Fund would have more
       than 5% of the value of its total assets  invested in the  securities of
       such issuer.  As a non-fundamental  operating  policy,  the Money Market
       Fund, in accordance  with Rule 2a-7 under the Investment  Company Act of
       1940,  as amended,  will not invest more than 5% of its total  assets in
       the securities (other than securities  issued by the U.S.  Government or
       any of its agencies or instrumentalities) issued by a single issuer.

 (8)   Invest more than 25% of the value of its total assets  (taken at current
       value at the time of each  investment)  in  securities  of issuers whose
       principal business activities are the same industry. With respect to the
       Money  Market  Fund,  banks are not  considered  a single  industry  for
       purposes of this policy.  This  limitation  does not apply to securities
       issued  or  guaranteed  by  the  U.S.  Government  or  its  agencies  or
       instrumentalities.

                                       6
<PAGE>

     With  respect  to the  Funds'  concentration  policy as  described  in the
Prospectus,  the Adviser uses industry  classifications for industries based on
categories  established by Standard & Poor's Corporation (S&P) for the Standard
& Poor's 500 Composite Index, with certain  modifications.  Because the Adviser
has determined  that certain  categories  within,  or in addition to, those set
forth by S&P have unique investment characteristics,  additional industries are
included  as  industry   classifications.   The  Adviser  classifies  municipal
obligations by projects with similar characteristics, such as toll road revenue
bonds, housing revenue bonds, or higher education revenue bonds.

                             PORTFOLIO TRANSACTIONS

     The  Adviser,  pursuant  to the  Advisory  Agreement,  and  subject to the
general  control of the Board of  Trustees,  places all orders for the purchase
and sale of Fund securities.  In executing portfolio transactions and selecting
brokers and dealers,  it is the Trust's policy to seek the best  combination of
price and  execution  available.  The Adviser will  consider such factors as it
deems  relevant,  including  the  breadth  of the market in the  security,  the
financial  condition and execution  capability  of the  broker-dealer,  and the
reasonableness of the commission,  if any, for the specific transaction or on a
continuing basis.  Securities purchased or sold in the over-the-counter  market
will be executed through  principal market makers,  except when, in the opinion
of the Adviser, better prices and execution are available elsewhere.

     The Trust has no obligation to deal with any particular broker or group of
brokers in the  execution of  portfolio  transactions.  The Trust  contemplates
that,  consistent  with  obtaining the best  combination of price and execution
available,  brokerage  transactions  may be  effected  through  USAA  Brokerage
Services,  a discount  brokerage service of the Adviser.  The Board of Trustees
has adopted  procedures in conformity with the requirements of Rule 17e-1 under
the 1940 Act that are designed to ensure that all brokerage commissions paid to
USAA  Brokerage  Services are  reasonable  and fair.  The Board of Trustees has
authorized the Adviser,  as a member of the Chicago Stock Exchange,  to effect,
through USAA Brokerage Services,  portfolio  transactions for the Trust on such
exchange and to retain  compensation in connection with such transactions.  Any
such  transactions  will be  effected  and  related  compensation  paid only in
accordance with applicable SEC regulations.

     In the  allocation of brokerage  business used to purchase  securities for
the Funds, preference may be given to those broker-dealers who provide research
or other services to the Adviser. Such research and other services may include,
for example:  advice  concerning the value of securities,  the  advisability of
investing  in,  purchasing,  or selling  securities,  and the  availability  of
securities  or the  purchasers or sellers of  securities;  analyses and reports
concerning  issuers,  industries,  securities,  economic  factors  and  trends,
portfolio  strategy,   and  performance  of  accounts;  and  various  functions
incidental  to  effecting  securities  transactions,   such  as  clearance  and
settlement.  In return  for such  services,  a Fund may pay to those  brokers a
higher  commission  than may be charged  by other  brokers,  provided  that the
Adviser determines in good faith that such commission is reasonable in terms of
either that  particular  transaction  or of the overall  responsibility  of the
Adviser  to the Funds and its other  clients.  The  receipt  of  research  from
broker-dealers  that execute  transactions on behalf of the Trust may be useful
to the Adviser in rendering  investment  management  services to other  clients
(including affiliates of the Adviser),  and conversely,  such research provided
by  broker-dealers  who have  executed  transaction  orders  on behalf of other
clients  may be useful to the Adviser in carrying  out its  obligations  to the
Trust.  While such  research is  available to and may be used by the Adviser in
providing  investment  advice to all its clients  (including  affiliates of the
Adviser),  not all of such  research may be used by the Adviser for the benefit
of the Trust. Such research and services will be in addition to and not in lieu
of research  and  services  provided by the  Adviser,  and the  expenses of the
Adviser  will not  necessarily  be reduced by the receipt of such  supplemental
research. See "The Trust's Adviser."

     Securities of the same issuer may be purchased,  held, or sold at the same
time by the Trust for any or all of its Funds,  or other  accounts or companies
for which the Adviser provides  investment advice (including  affiliates of the
Adviser).  On  occasions  when the  Adviser  deems  the  purchase  or sale of a
security  to be in the best  interest  of the Trust,  as well as the  Adviser's
other  clients,  the Adviser,  to the extent  permitted by applicable  laws and
regulations,  may  aggregate  such  securities  to be sold or purchased for the
Trust with those to be sold or purchased for other customers in order to obtain
best  execution  and  lower  brokerage  commissions,  if any.  In  such  event,
allocation  of the  securities  so purchased  or sold,  as well as the expenses
incurred  in the  transaction,  will be made by the  Adviser  in the  manner it
considers to be most equitable and consistent with its fiduciary obligations to
all such  customers,  including the Trust,  and in accordance  with  procedures
approved by the Board of Trustees. In some instances, this procedure may impact
the price and size of the position obtainable for the Trust.

BROKERAGE COMMISSIONS

     During the fiscal year ended  December 31, 1998,  the Growth & Income Fund
purchased securities of Morgan Stanley, Dean Witter,  Discover & Co., the World
Growth Fund purchased  securities of Morgan  Stanley,  Dean Witter,  Discover &
Co., and the  Diversified Assets Fund  purchased  securities of Merrill Lynch &
Co., Inc., which are regular broker-dealers (the
 
                                       7

ten largest  broker-dealers  through whom the Fund purchased securities) or the
parents of regular  broker-dealers.  These securities had values of $1,988,000,
$355,000, and $1,002,000, respectively, as of December 31, 1998.


     The Trust pays no brokerage  commissions as such for debt securities.  The
market for such securities is typically a "dealer"  market in which  investment
dealers buy and sell the  securities  for their own  accounts,  rather than for
customers,  and the price may  reflect a  dealer's  mark-up  or  mark-down.  In
addition, some securities may be purchased directly from issuers.

     During the last three fiscal years,  the Funds paid the following  amounts
in brokerage commissions.

     were effected through USAA Brokerage Services.

     For the year ended December 31, 1998,  6.90%,  7.28%,  27.07% and 4.10% of
the  aggregate  dollar  amounts  of  transactions   involving  the  payment  of
commissions  by the Growth and Income  Fund,  World  Growth  Fund,  Diversified

     Certain Funds paid  brokerage  commissions  in connection  with  brokerage
transactions  that were  directed to brokers  because of brokerage and research
services  provided by such  brokers.  For the Trust's most  recently  completed
fiscal year ended December 31, 1998, the amount of such brokerage  transactions

PORTFOLIO TURNOVER RATES

     The rate of portfolio  turnover in any of the Funds will not be a limiting
factor when the Adviser deems changes in a Fund's portfolio appropriate in view
of its investment objective.  Although no Fund will purchase or sell securities
solely  to  achieve  short-term  trading  profits,  a Fund may  sell  portfolio
securities  without  regard to the length of time held if  consistent  with the
Fund's investment objective.  A higher degree of equity portfolio activity will
increase  brokerage costs to a Fund. It is not  anticipated  that the portfolio
turnover rate of any Fund,  other than the Money Market Fund and the Aggressive
Growth Fund, will exceed 100%.

                                       8
<PAGE>

     The  portfolio  turnover rate is computed by dividing the dollar amount of
securities  purchased or sold  (whichever  is smaller) by the average  value of
securities  owned during the year.  Short-term  investments  such as commercial
paper  and  short-term  U.S.  Government  securities  are not  considered  when
computing the turnover rate.

                          DESCRIPTION OF TRUST SHARES

     The Trust is authorized to issue shares of beneficial interest in separate
Funds. Seven Funds have been established.  Under the Master Trust Agreement, as
amended  February 7, 1997,  and as further  amended  February  18, 1998 ("Trust
Agreement"),  the  Board of  Trustees  is  authorized  to  create  new Funds in
addition to those already existing without shareholder approval.

     Each Fund's assets and all income, earnings, profits and proceeds thereof,
subject only to the rights of  creditors,  are  specifically  allocated to each
Fund.  They  constitute the underlying  assets of each Fund, are required to be
segregated on the books of account,  and are to be charged with the expenses of
such Fund.  Any  general  expenses  of the Trust not  readily  identifiable  as
belonging  to a  particular  Fund are  allocated  on the  basis  of the  Funds'
relative net assets during the fiscal year or in such other manner as the Board
of  Trustees  determines  to be fair and  equitable.  Each  share of each  Fund
represents an equal proportionate  interest in that Fund with every other share
of that Fund and is  entitled to  dividends  and  distributions  out of the net
income and capital  gains  belonging to that Fund when declared by the Board of
Trustees.  Upon liquidation of the Fund, shareholders are entitled to share pro
rata in the net assets belonging to such Fund available for distribution.

     Under  Delaware  law,  the Trust is not required to hold annual or special
meetings  of  shareholders  and the  Trust  does  not  expect  to hold any such
meetings  unless required by the 1940 Act.  Special  meetings may be called for
purposes such as electing or removing Trustees,  changing fundamental policies,
or approving an investment advisory contract. Also, the holders of an aggregate
of at least 10% of the outstanding shares of the Trust may request a meeting at
any time for the purpose of voting to remove one or more of the Trustees.

     Pursuant to the Trust Agreement, any Trustee may be removed by the vote of
two-thirds of the Trust shares then outstanding,  cast in person or by proxy at
any meeting called for the purpose.  Under the Trust Bylaws, the Trustees shall
promptly call and give notice of a meeting of  shareholders  for the purpose of
voting  upon  removal  of any  Trustee  when  requested  to do so in writing by
shareholders  holding  not less then 10% of the shares  then  outstanding.  The
Trust will assist in communicating to other shareholders about the meeting.

     The  voting   privileges  of  Contract  Owners  and  Policy  Owners,   and
limitations on those  privileges,  are explained in the prospectus  relating to
the  Contracts  or  Policies.  USAA  Life,  as the  owner of the  assets in the
Separate  Account and Life Insurance  Separate  Account,  will vote Fund shares
that are held in the Separate Accounts to fund benefits under the Contracts and
Policies in  accordance  with the  instructions  of Contract  Owners and Policy
Owners.  This practice is commonly referred to as "pass-through"  voting.  USAA
Life  also will vote for or  against  any  proposition,  or will  abstain  from
voting,  any Fund  shares  attributable  to a  Contract  or Policy for which no
timely voting instructions are received,  and any Fund shares held by USAA Life
for its own account,  in proportion to the voting instructions that it receives
with respect to all Contracts  and Policies  participating  in that Fund.  This
practice is commonly  referred  to as "mirror" or "echo"  voting.  If USAA Life
determines,  however,  that it is  permitted to vote any Fund shares in its own
right, it may elect to do so, subject to the then-current interpretation of the
1940 Act and the rules thereunder.

     On any matter submitted to the shareholders, the holder of each Fund share
is  entitled to one vote per share (with  proportionate  voting for  fractional
shares)  regardless  of the  relative  NAV of the Fund's  shares.  However,  on
matters  affecting an  individual  Fund  differently  from the other  Funds,  a
separate vote of the  shareholders of that Fund is required.  Shareholders of a
Fund are not  entitled to vote on any matter that does not affect that Fund but
that requires a separate vote of another  Fund.  Shares do not have  cumulative
voting  rights,  which means the holders of more than 50% of the shares  voting
for the election of Trustees  can elect 100% of the Board of Trustees,  and the
holders of less than 50% of the shares voting for the election of Trustees will
not be able to elect any person as a Trustee. Shareholders of a particular Fund
might have the power to elect all of the  Trustees  of the Trust  because  that
Fund has a majority of the total outstanding shares of the Trust.

     When issued, each Fund's shares are fully paid and nonassessable,  have no
pre-exemptive or subscription rights, and are fully transferable.  There are no
conversion rights.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

     Each Fund  intends to  qualify as a  regulated  investment  company  under
Subchapter M of the Internal  Revenue  Code of 1986 (the  "Code"),  as amended.
Accordingly, no Fund will be liable for federal income taxes on its taxable net
investment  income and net capital  gains  (capital  gains in excess of capital
losses)  that  are  distributed  to  shareholders,   provided  that  each  Fund
distributes  at  least  90% of its net  investment  income  and net  short-term
capital gain for the taxable year.

                                       9
<PAGE>

     To qualify as a regulated  investment  company,  a Fund must,  among other
things,  (1) derive in each  taxable year at least 90% of its gross income from
dividends,  interest, payments with respect to securities loans, gains from the
sale or other disposition of stock, securities or foreign currencies,  or other
income  derived  with  respect to its  business  of  investing  in such  stock,
securities or  currencies  (the 90% test) and; (2) satisfy  certain  investment
diversification requirements at the close of each quarter of the Fund's taxable
year.  Each of the Funds  intends to  satisfy  both of these  requirements.  To
deduct the dividends it pays,  and  therefore not be subject to federal  income
tax at the Trust level, each Fund must pay dividends each taxable year equal to
90%  of  its  taxable  income,  excluding  net  capital  gain,  and  90% of its
non-taxable interest income.

     Each Fund is subject to asset  diversification  requirements  described by
the U.S. Treasury Department under Section 1.817-5 of the Treasury Regulations.
The regulations  generally provide that, as of the end of each calendar quarter
or within 30 days  thereafter,  no more than 55% of the total  assets of a Fund
may be  represented  by  any  one  investment,  no  more  than  70% by any  two
investments, no more than 80% by any three investments, and no more than 90% by
any four investments.  For this purpose,  all securities of the same issuer are
considered a single  investment.  Furthermore,  each U.S.  Government agency or
instrumentality  is treated as a separate  issuer.  There are also  alternative
diversification  requirements  that may be  satisfied  by the  Funds  under the
regulations.

     In  addition,  shares  of each  Fund  may be  owned  only by (a)  separate
accounts of USAA Life (or other life insurance companies), (b) a life insurance
company general account, (c) USAA IMCO or an affiliate, in starting or managing
a Fund  (in  the  case  of (b) and  (c) of  this  paragraph,  there  must be no
intention  to sell  shares to the  general  public),  or (d) the  trustee  of a
qualified pension or retirement plan.

     In addition to these rules,  the Treasury has  indicated  that it might in
the future  issue a  regulation  or a revenue  ruling on the issue of whether a
variable  contract  owner  is  exercising   impermissible  "control"  over  the
investments  underlying a segregated asset account,  thereby causing the income
earned on a Contract or Policy to be taxed currently.

     Each Fund intends to comply with the diversification  requirements. If the
Funds or a Fund should fail to comply with these diversification  requirements,
or fails to meet the  requirements  of Subchapter M of the Code,  Contracts and
Policies  invested  in the Funds would not be treated as annuity  contracts  or
life insurance for income tax purposes  under the Code. In that case,  Contract
owners  and  Policy  owners  would be taxed  on the  increases  in value of any
Contract or Policy that invested through the separate  accounts of USAA Life in
a Fund that  failed  these  tests for the period of failure  and  subsequently.
Also, if the insured under a Policy died during a period of failure,  a portion
of the death benefit would be taxable to the recipient.

     The Code imposes a nondeductible  4% excise tax on a regulated  investment
company that fails to  distribute  during each calendar year an amount at least
equal  to the sum of (1)  98% of its  taxable  net  investment  income  for the
calendar year,  (2) 98% of its capital gain net income for the 12-month  period
ending on October  31, and (3) any prior  amounts  not  distributed.  Each Fund
intends to make such  distributions as are necessary to avoid imposition of the
excise tax. The 4% excise tax applies where a Fund sells to a separate account,
ONLY where a general  account of a life company or an adviser invests more than
$250,000 in the Fund.

     The ability of the  Aggressive  Growth  Fund,  World  Growth Fund, and the
International Fund to make certain  investments may be limited by provisions of
the Code that require  inclusion of certain  unrealized  gains or losses in the
Fund's income for purposes of the 90% test, and the  distribution  requirements
of the Code, and by provisions of the Code that characterize  certain income or
loss as  ordinary  income  or loss  rather  than  capital  gain or  loss.  Such
recognition,  characterization, and timing rules generally apply to investments
in certain forward currency  contracts, foreign currencies, and debt securities
denominated in foreign currencies, as well as certain other investments.

     The World  Growth  Fund and  International  Fund may be subject to foreign
withholding  or other taxes.  If more than 50% of the value of the Fund's total
assets at the close of any  taxable  year  consists  of  securities  of foreign
corporations,  the Fund may file an election with the Internal  Revenue Service
(the Foreign  Election) that would permit USAA Life Insurance Company to take a
credit (or a  deduction)  for  foreign  income  taxes paid by the Fund.  If the
Foreign  Election is made,  USAA Life  Insurance  Company  would include in its
gross income both  dividends  received  from the Fund and foreign  income taxes
paid by the Fund. As a shareholder of the Fund(s),  USAA Life Insurance Company
would be  entitled  to treat the  foreign  income  taxes  withheld  as a credit
against its U.S. federal income taxes,  subject to the limitations set forth in
the Code with respect to the foreign tax credit generally.  Alternatively, USAA
Life Insurance  Company could,  if it were to its advantage,  treat the foreign
income taxes withheld as a deduction in computing taxable income rather than as
a tax credit. USAA Life Insurance Company will not be entitled to a foreign tax
credit for taxes paid to certain  countries;  however,  if the Funds  otherwise
qualify for the Foreign Election,  a deduction for such taxes will be available
to it. It is anticipated that the Funds will make the Foreign Election.

     If the World  Growth Fund or the  International  Fund invests in an entity
that is classified as a Passive Foreign Investment Company ("PFIC") for federal
income tax purposes, the application of certain provisions of the Code applying
to PFICs could result in the imposition of certain  federal income taxes on the
Fund. It is anticipated  that any taxes on the Fund with respect to investments
in PFICs would be insignificant.

COMMITTEES OF THE BOARD OF TRUSTEES

     The Trust has an Audit Committee,  an Executive  Committee,  and a Pricing
and  Investment  Committee.  The  duties of these  three  Committees  and their
present membership are as follows:

AUDIT  COMMITTEE:  The members of the Audit Committee  consult with the Trust's
independent  public  accountants  from  time to time  regarding  financial  and
accounting   matters  pertaining  to  the  Trust  and  meet  with  the  Trust's
independent  public accountants at least once annually to discuss the scope and
results  of the  annual  audit of the  Funds  and  such  other  matters  as the
Committee  members deem  appropriate or desirable.  Trustees Reedy,  Stone, and
West are members of the Audit Committee.

EXECUTIVE  COMMITTEE:  During  intervals  between  meetings  of  the  Board  of
Trustees,  the Executive Committee possesses and may exercise all of the powers
of the Board of  Trustees  in the  management  of the Trust  except as to those
matters that  specifically  require  action by the Board of Trustees.  Trustees
Rosane, Roth, and Reedy are members of the Executive Committee.

PRICING AND INVESTMENT  COMMITTEE:  During  intervals  between  meetings of the

                              THE TRUST'S ADVISER

     As described in the Prospectus,  USAA IMCO is the Adviser to the Trust and
provides  services  under the  Advisory  Agreement.  USAA IMCO,  a wholly owned
indirect subsidiary of United Services Automobile Association, was organized in
May 1970 and has served as adviser and distributor for the USAA Life Investment
Trust from its inception.

     In  addition  to  providing  investment  advice to the Trust,  the Adviser
advises and manages the  investments  for USAA and its affiliated  companies as
well as those of USAA Investment Trust, USAA Mutual Fund, Inc., USAA Tax Exempt
Fund,  Inc., and USAA State Tax-Free  Trust.  As of the date of this SAI, total
assets under management by the Adviser were approximately $40 billion, of which
approximately $25 billion are in mutual fund portfolios.

THE ADVISORY AGREEMENT

     Under the Advisory Agreement,  the Adviser provides an investment program,
carries out the investment  policies and manages the portfolio  assets for each
Fund.  The  Adviser  is  authorized,  subject  to the  control  of the Board of
Trustees, to determine the selection, amount and time to buy or sell securities
for each Fund. For these services under the Advisory  Agreement,  the Trust has
agreed to pay the  Adviser a monthly  fee equal to the annual  rate of 0.20% of
the monthly average net assets of each Fund,  other than the Aggressive  Growth
Fund and the  International  Fund,  for  which the  annual  rates are 0.50% and
0.65%, respectively.

     For the  last  three  fiscal  years,  USAA  IMCO  received  the  following
investment advisory fees:

     International Fund          $ 146,670      $  92,044          N/A

     The Advisory Agreement was most recently approved by the Board of Trustees
on November 18, 1998, for a term ending January 2, 2000. The Advisory Agreement
will continue in effect from year to year  thereafter  for each Fund as long as
it is approved at least annually by a vote of the outstanding voting securities
of such  Fund (as  defined  by the 1940 Act) or by the  Board of  Trustees  (on
behalf of such Fund) and, in either  event,  a majority of the Trustees who are
not interested

                                      13

persons  of the  Adviser or of the Trust  (otherwise  than as  Trustees),  at a
meeting  called  for the  purpose  of voting  on such  approval.  The  Advisory
Agreement  may be  terminated,  without  penalty,  at any time by the  Board of
Trustees,  the  Adviser or,  with  respect to any Fund,  by vote of that Fund's
shareholders,  in each case on 60 days' written notice.  It will  automatically
terminate in the event of its assignment (as defined in the 1940 Act).

outstanding shares as shown below.

                  Money Market Fund                         -
                  Income Fund                             50.02%

     As a result of its  beneficial  ownership,  USAA Life may be  presumed  to
control  (with the  exception of the Money Market Fund) each Fund of the Trust.
Such control may dilute the effect of the votes of other  shareholders  of each
Fund  presumed  to be  controlled.  USAA Life will vote its Fund  shares  owned
through the Separate Account and Life Insurance  Separate Account in accordance
with   instructions   received   from   Contract   Owners  (or   annuitants  or
beneficiaries,  to the extent  provided in the  Contracts)  and Policy  Owners,
respectively.  If USAA Life determines,  however,  that it is permitted to vote
any Fund shares that it owns in its own right,  either  directly or through the
Separate  Account or Life Insurance  Separate  Account,  it may elect to do so,
subject  to the  then-current  interpretation  of the  1940  Act and the  rules
thereunder.  The address of USAA Life is 9800 Fredericksburg Road, San Antonio,
Texas 78288. USAA Life, a Texas corporation, is wholly owned by United Services
Automobile Association.

     As of  January  31,  1999,  the  Separate  Account  owned  of  record  the
percentages of each Fund's outstanding shares attributable to the Contracts and
Policies as shown below. The Separate Account is located at 9800 Fredericksburg
Road, San Antonio, Texas 78288.

                  International Fund                       6.64%

     Contract Owners and Policy Owners may be deemed to beneficially own shares
of one or more of the  Funds,  to the  extent  that they are given the right to
provide voting instructions with regard to shares in those Funds. The following
table  identifies  all persons who as of January  31,  1999,  held of record or

     As of January 31, 1999, the Trustees and officers,  as a group, owned less
than 1% of the Trust's  outstanding  voting  securities  through any  Contract.
There are no family relationships among the Trustees,  officers, and managerial
level employees of the Trust or its Adviser.

                        CALCULATION OF PERFORMANCE DATA

     Information  regarding  the total  return of the Funds is  provided in the
"Fund  Performance"  section for each Fund under "Fund Objectives,  Strategies,
and Risks" in the  Prospectus.  See "Valuation of Securities" in this SAI for a
discussion of the manner in which the Funds' price per share is calculated.

     Total  return  and yield  quotations  reflect  only the  performance  of a
hypothetical investment in the Fund during a specified period. These quotations
are based on historical  data and do not in any way indicate or project  future
performance.  Quotations  of a Fund's  total  return  and yield do not  reflect
charges or  deductions  against  the Fund  Account or  charges  and  deductions
against the Contracts or Policies.  The share price of the Income Fund,  Growth
and Income Fund, World Growth 

                                      15
<PAGE>

Fund,  Diversified Assets Fund,  Aggressive Growth Fund, and International Fund
will vary  and,  when  redeemed,  may be worth  more or less than the  original
purchase price. The yield of the Money Market Fund will also vary.

     Charges  imposed  under the Contract  and Policies  will affect the actual
return to Contract and Policy Owners.  Charges  imposed under the Contracts and
Policies are not included in the  calculation  of Yield or Total Return for the
Funds shown below.  See the  prospectuses  for the  Contracts  and Policies for
further information.

YIELD

     The yield of a Fund refers to the income generated by an investment in the
Fund over a specific  period  (seven days in the case of the Money Market Fund,
30 days in the case of all other  Funds),  excluding  realized  and  unrealized
capital  gains  and  losses  in the  Fund's  investments.  This  income is then
"annualized" and shown as a percentage of the investments.

MONEY MARKET FUND

     When the Money Market Fund quotes a current  annualized yield, it is based
on a  specified  recent  seven-day-calendar  period.  It  is  computed  by  (1)
determining  the net change,  exclusive of capital  changes,  in the value of a
hypothetical  pre-existing  account  having  a  balance  of  one  share  at the
beginning of the period,  (2)  dividing the net change in account  value by the
value of the  account at the  beginning  of the base  period to obtain the base
return,  then (3) multiplying  the base period by 52.14 (365/7).  The resulting
yield figure is carried to the nearest hundredth of one percent.

     The  calculation  includes the value of additional  shares  purchased with
dividends  on the  original  share,  and other  dividends  declared on both the
original share and any such additional  shares,  and any expenses and fees that
may be charged to the fund. The calculation  includes the effect of all expense
reimbursements  to the Fund. The capital changes  excluded from the calculation
are  realized  capital  gains  and  losses  from  the  sale of  securities  and
unrealized appreciation and depreciation.

     The Fund's effective  (compounded)  yield will be computed by dividing the
seven-day annualized yield as defined above by 365, adding one to the quotient,
raising the sum to a power equal to 365 divided by seven,  and  subtracting one
from the result.

     Current and effective  yields  fluctuate  daily and will vary with factors
such as  interest  rates and the  quality,  length of  maturities,  and type of
investments in the portfolio.

                Yield for 7-day Period ended December 31, 1998, was 5%.
      Effective Yield for 7-day Period ended December 31. 1998, was 5.13%.

OTHER FUNDS

     The Funds may  advertise  performance  in terms of a 30-day (or one month)
yield  quotation.  The 30-day  yield  quotation is computed by dividing the net
investment  income per share earned  during the period by the maximum  offering
price  per  share on the last day of the  period,  according  to the  following
formula:

                        Yield = 2[((a-b)/(cd)+1)^6 -1]
Where:
     a = dividends and interest earned during the period
     b = expenses accrued for the period (net of reimbursement)
     c = the average daily number of shares  outstanding during the period that
         were entitled to receive dividends
     d = the maximum offering price per share on the last day of the period

TOTAL RETURN

     The Funds may  advertise  performance  in terms of  average  annual  total
return for one-, five-, and ten-year periods, or for such lesser periods as any
of such Funds have been in existence.  Average  annual total return is computed
by finding the average annual compounded  rates of return over the periods that
would  equate the  initial  amount  invested  to the ending  redeemable  value,
according to the following formula prescribed by the SEC:

                                P(1 + T)n = ERV

 Where:    P  = a hypothetical initial investment of $1,000
           n  = number of years
         ERV  = ending redeemable value of a hypothetical $1,000 investment
                made at the beginning of the applicable period

     The calculation  assumes all dividends and  distributions by such Fund are
reinvested  at the price stated in the  Prospectus  on the  reinvestment  dates
during the period, and includes all Fund expenses, net of reimbursements.

                                      16
<PAGE>

     In  addition,  the  Funds  may  each  advertise  performance  in  terms of
cumulative  total return.  Cumulative total return reflects the total change in
value of an investment in the Fund over a specified period,  including, but not
limited to, periods of one, five and ten years,  or the period since the Fund's
inception  through a stated ending date.  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 investment of $1,000
          C   = cumulative total return
        ERV   = ending redeemable value of a hypothetical $1,000 investment
                made at the beginning of the applicable period

     The average  annual and  cumulative  total returns* for each Fund that had
operations were as follows:

               APPENDIX A - LONG-TERM AND SHORT-TERM DEBT RATINGS

1.       LONG-TERM DEBT RATINGS:

MOODY'S INVESTORS SERVICE, INC. ("MOODY'S")

Aaa        Bonds that are rated Aaa are judged to be of the best quality.  They
           carry the  smallest  degree  of  investment  risk and are  generally
           referred to as "gilt  edged."  Interest  payments are protected by a
           large or by an exceptionally  stable margin and principal is secure.
           While the various  protective  elements  are likely to change,  such
           changes  as can be  visualized  are  most  unlikely  to  impair  the
           fundamentally strong position of such issues.

Aa         Bonds  that are  rated Aa are  judged to be of high  quality  by all
           standards.  Together  with  the Aaa  group  they  comprise  what are
           generally known as "high-grade bonds." They are rated lower than the
           best bonds because  margins of protection  may not be as large as in
           Aaa  securities  or  fluctuation  of  protective  elements may be of
           greater  amplitude or there may be other elements present which make
           the long-term risks appear somewhat larger than in Aaa securities.

A          Bonds that are rated A possess many favorable investment  attributes
           and are to be considered as upper-medium- grade obligations. Factors
           giving  security to principal and interest are considered  adequate,
           but  elements  may be  present  that  suggest  a  susceptibility  to
           impairment sometime in the future.

Baa        Bonds that are rated Baa are considered as medium-grade obligations,
           (i.e.,  they are  neither  highly  protected  nor  poorly  secured).
           Interest  payments and principal  security  appear  adequate for the
           present but  certain  protective  elements  may be lacking or may be
           characteristically  unreliable  over any great length of time.  Such
           bonds lack outstanding  investment  characteristics and in fact have
           speculative characteristics as well.

NOTE:  MOODY'S APPLIES  NUMERICAL  MODIFIERS 1, 2, AND 3 IN EACH GENERIC RATING
CLASSIFICATION.  THE  MODIFIER 1  INDICATES  THAT THE  OBLIGATION  RANKS IN THE
HIGHER END OF ITS GENERIC RATING CATEGORY, THE MODIFIER 2 INDICATES A MID-RANGE
RANKING,  AND THE  MODIFIER  3  INDICATES  A  RANKING  IN THE LOWER END OF THAT
GENERIC RATING CATEGORY.

 STANDARD & POOR'S RATINGS GROUP ("S&P")

AAA        Debt rated AAA has the highest rating assigned by S&P. The obligor's
           capacity  to meet its  financial  commitment  on the  obligation  is
           extremely strong.

AA         An obligation  rated "AA" differs from the highest rated issues only
           in small  degree.  The  obligor's  capacity  to meet  its  financial
           commitment on the obligation is very strong.

A          An obligation  rated "A" is somewhat more susceptible to the adverse
           effects of changes in  circumstances  and economic  conditions  than
           obligations  in higher  rated  categories.  However,  the  obligor's
           capacity to meet its financial commitment on the obligation is still
           strong.

BBB        An obligation rated "BBB" exhibits adequate capacity to pay interest
           and  repay  principal.   However,  adverse  economic  conditions  or
           changing  circumstances  are  more  likely  to  lead  to a  weakened
           capacity  of the  obligor to meet its  financial  commitment  on the
           obligation.

PLUS (+) OR MINUS (-):  THE  RATINGS  FROM "AA" TO "CCC" MAY BE MODIFIED BY THE
ADDITION  OF A PLUS OR MINUS SIGN TO SHOW  RELATIVE  STANDING  WITHIN THE MAJOR
RATING CATEGORIES.

FITCH IBCA, Inc. ("FITCH IBCA")

AAA        Highest credit quality.  `AAA' ratings denote the lowest expectation
           of credit  risk.  They are  assigned  only in case of  exceptionally
           strong  capacity for timely payment of financial  commitments.  This
           capacity is highly unlikely to be adversely  affected by foreseeable
           events.

AA         Very high credit quality. 'AA' ratings denote a very low expectation
           of credit  risk.  They  indicate  very  strong  capacity  for timely
           payment of financial commitments. This capacity is not significantly
           vulnerable to foreseeable events.

A          High credit quality.  'A' ratings denote a low expectation of credit
           risk.  The capacity for timely  payment of financial  commitments is
           considered  strong.  This  capacity  may,   nevertheless,   be  more
           vulnerable  to changes in  circumstances  or in economic  conditions
           than is the case for higher ratings.

                                      18
<PAGE>

BBB        Good credit quality.  'BBB' ratings indicate that there is currently
           a low expectation of credit risk. The capacity for timely payment of
           financial commitments is considered adequate, but adverse changes in
           circumstances  and in economic  conditions are more likely to impair
           this capacity. This is the lowest investment-grade category.

PLUS (+) MINUS(-)  SIGNS ARE USED WITH A RATING SYMBOL TO INDICATE THE RELATIVE
POSITION OF A CREDIT WITHIN THE RATING CATEGORY. PLUS AND MINUS SIGNS, HOWEVER,
ARE NOT USED IN THE AAA CATEGORY.

DUFF & PHELPS, INC. ("D&P"):

AAA        Highest credit quality. The risk factors are negligible,  being only
           slightly more than for risk-free U.S. Treasury debt.

AA         High credit quality.  Protection factors are strong.  Risk is modest
           but  may  vary  slightly  from  time  to time  because  of  economic
           conditions.

A          Protection factors are average but adequate.  However,  risk factors
           are variable and greater in periods of economic stress.

BBB        Below average protection factors but still considered sufficient for
           prudent investment. Considerable variability in risk during economic
           cycles.

2.       SHORT-TERM DEBT RATINGS:

MOODY'S CORPORATE AND GOVERNMENT

Prime-1    Issuers rated Prime - 1 (or supporting institutions) have a superior
           ability for repayment of senior short-term debt obligations. Prime-1
           repayment  ability will often be evidenced by many of the  following
           characteristics:

           * Leading market positions in well-established industries.
           * High rates of return on funds employed.
           * Conservative  capitalization  structure with moderate  reliance on
             debt and ample asset protection.
           * Broad margins in earnings  coverage of fixed financial charges and
             high internal cash generation.
           * Well-established  access  to  a  range  of  financial  markets and
             assured sources of alternate liquidity.

Prime-2    Issuers rated Prime - 2 (or supporting  institutions)  have a strong
           ability for repayment of senior  short-term debt  obligations.  This
           will  normally be  evidenced  by many of the  characteristics  cited
           above but to a lesser degree.  Earnings trends and coverage  ratios,
           while  sound,  may be  more  subject  to  variation.  Capitalization
           characteristics,  while still  appropriate,  may be more affected by
           external conditions. Ample alternate liquidity is maintained.

Prime-3    Issuers  rated  Prime  - 3  (or  supporting  institutions)  have  an
           acceptable  ability for repayment of senior short-term  obligations.
           The effect of industry  characteristics  and market compositions may
           be more pronounced.  Variability in earnings and  profitability  may
           result in changes in the level of debt protection  measurements  and
           may require relatively high financial  leverage.  Adequate alternate
           liquidity is maintained.

MOODY'S MUNICIPAL

MIG1/VMIG 1       This  designation  denotes  best  quality.  There is  present
                  strong   protection  by  established  cash  flows,   superior
                  liquidity support, or demonstrated  broad-based access to the
                  market for refinancing.

MIG 2/VMIG 2      This designation  denotes high quality. Margins of protection
                  are ample although not so large as in the preceding group.

MIG3/VMIG 3       This  designation  denotes  favorable  quality.  All security
                  elements  are   accounted   for  but  there  is  lacking  the
                  undeniable  strength of the preceding  grades.  Liquidity and
                  cash flow  protection  may be narrow  and  market  access for
                  refinancing is likely to be less well established.

MIG 4/VMIG  4     This  designation   denotes  adequate   quality.   Protection
                  commonly  regarded as required of an  investment  security is
                  present  and  although  not   distinctly   or   predominantly
                  speculative, there is specific risk.

S&P CORPORATE AND GOVERNMENT

A-1        This highest category  indicates that the degree of safety regarding
           timely  payment  is  strong.  Those  issues  determined  to  possess
           extremely strong safety  characteristics are denoted with a plus (+)
           sign designation.

                                      19
<PAGE>

A-2        Capacity  for timely  payment  on issues  with this  designation  is
           satisfactory.  However, the relative degree of safety is not as high
           as for issues designated A-1.

A-3        Issues carrying this designation  have adequate  capacity for timely
           payment.  They are, however,  more vulnerable to the adverse effects
           of changes in  circumstances  than  obligations  carrying the higher
           designations.

S&P MUNICIPAL

SP-1       Strong capacity to pay principal and interest.  Issues determined to
           possess   very   strong   characteristics   are  given  a  plus  (+)
           designation.

SP-2       Satisfactory  capacity  to pay  principal  and  interest,  with some
           vulnerability  to adverse  financial  and economic  changes over the
           term of the notes.

FITCH IBCA, INC.

F-1        Highest credit quality.  Indicates the strongest capacity for timely
           payment of  financial  commitments;  may have an added "+" to denote
           any exceptionally strong credit feature.

F-2        Good credit quality.  A satisfactory  capacity for timely payment of
           financial  commitments,  but the margin of safety is not as great as
           in the case of the higher ratings.

F-3        Fair credit  quality.  The capacity for timely  payment of financial
           commitments is adequate;  however,  near-term  adverse changes could
           result in a reduction to non-investment grade.

D&P

D-1+       Highest certainty of timely payment. Short-term liquidity, including
           internal  operating  factors  and/or  ready  access  to  alternative
           sources of funds, is outstanding, and safety is just below risk-free
           U.S.
           Treasury short-term obligations.

D-1        Very  high  certainty  of  timely  payment.  Liquidity  factors  are
           excellent and supported by good fundamental protection factors. Risk
           factors are minor.

D-1-       High certainty of timely payment.  Liquidity  factors are strong and
           supported by good fundamental  protection factors.  Risk factors are
           very small.

D-2        Good  certainty  of timely  payment.  Liquidity  factors and company
           fundamentals  are sound.  Although ongoing funding needs may enlarge
           total financing requirements, access to capital markets is good.
           Risk factors are small.

D-3        Satisfactory liquidity and other protection factors qualify issue as
           to  investment  grade.  Risk  factors are larger and subject to more
           variation. Nevertheless, timely payment is expected.

THOMPSON BANKWATCH, INC. ("TBW")

TBW-1      The  highest  category;   indicates  a  very  high  likelihood  that
           principal and interest will be paid on a timely basis.

TBW-2      The second highest  category;  while the degree of safety  regarding
           timely  repayment of principal and interest is strong,  the relative
           degree of safety is not as high as for issues rated TBW-1.

TBW-3      The  lowest  investment  grade  category;  indicates  that while the
           obligation  is  more  susceptible  to  adverse   developments  (both
           internal and external) than those with higher ratings,  the capacity
           to service  principal and interest in a timely fashion is considered
           adequate.
