     FDIC or any other government agency.

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  Funds  principal  investment  strategy  is to invest  the Funds  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,
      bankers 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 decline due to an increase 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.

                                      B-4
<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.

                                                     for a quarter was 1.35%
                                                     (quarter ending December

          January 5, 1995.                           total return for a quarter
                                                     was 1.24%(quarter ending
                                                     December 31, 1998).

   ========================================================================

[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 FUNDS 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%.

PORTFOLIO MANAGER

Pamela K. Bledsoe,  Assistant Vice President of Money Market Funds, has managed
the Fund since June 10, 1996. Ms. Bledsoe has ten years  investment  management
experience and has worked for us for seven years.

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, which 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 decline because of an increase 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.

                                      B-6
<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  because of falls in the 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.

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, which 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  because of falls in the 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, which 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  because of falls in the 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


                                      B-10
<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% of the Fund's assets 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,  is  expected  in the long run to
entail  less  market  risk (and  potentially  less  return)  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, which 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  because  of falls  in the  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 decline because of an increase 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.

                                     B-12
<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, which 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  because of falls in the 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.

                                     B-14
<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.

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, which 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  because of falls in the 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 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  $____
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  of 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  

                                     B-18
<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 Funds
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 Funds  financial
statements, are included in the Annual Report, which is available upon request.

                                   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 Funds  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  Funds  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 Funds net assets and up to 10% of the USAA Life
Money  Market  Funds  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 Funds 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 Funds 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 Funds 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).  

                                     B-24
<PAGE>

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  Funds  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  Funds   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 Funds 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 Funds 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,  we 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.
    

                                  DISTRIBUTOR

   
     USAA Investment Management Company ("USAA IMCO" or the "Adviser"),  serves
as principal underwriter for the Trust in the distribution of shares,  pursuant
to an Underwriting and Administrative  Services  Agreement,  dated December 16,
1994, as amended and restated as of February 18, 1998.  USAA IMCO, an affiliate
of USAA Life, is registered as a broker-dealer with the SEC and a member of the
National Association of Securities Dealers, Inc. (the "NASD").

     USAA IMCO also serves as  distributor  of the Contracts and Polices funded
by Trust shares.  The Contracts and Policies are primarily sold in a continuous
offering by direct response through salaried sales account  representatives who
are  appropriately  licensed under state law to sell variable annuity contracts
and variable life insurance policies and registered with the NASD as registered
representatives and/or principals.
    

                               INVESTMENT ADVISER

     USAA IMCO,  registered  as an  investment  adviser  with the SEC under the
Investment Advisers Act of 1940, is the investment adviser to the Trust.

                                   CUSTODIAN

     State Street Bank and Trust  Company,  225  Franklin  Street,  Boston,  MA
02110,  is the Trust's  custodian  ("Custodian").  The Custodian is responsible
for,  among other things,  safeguarding  and  controlling  the Trust's cash and
securities,  handling the receipt and delivery of  securities,  and  collecting
interest on the Trust's  investments.  In addition,  each Fund's investments in
foreign  securities may be held by certain foreign banks and foreign securities
depositories  as  agents  of the  Custodian  in  accordance  with the rules and
regulations established by the SEC.

                                 TRANSFER AGENT

     USAA Life,  the depositor of the Separate  Account and the Life  Insurance
Separate Account, serves as transfer agent for the Trust pursuant to a Transfer
Agent Agreement, as amended by a Letter Agreement,  dated February 7, 1997, and
as further  amended  February 18,  1998.  USAA Life may be  reimbursed  for its
expenses  incurred in connection  with  providing  services  under the Transfer
Agent Agreement.

   
                              INDEPENDENT AUDITORS

     KPMG  LLP,  112  East  Pecan,  Suite  2400,  San  Antonio,   Texas  78205,
independent  auditors,  will  perform an annual  audit of USAA Life  Investment
Trust.
    

                                 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

     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
<PAGE>
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.

     During the last three fiscal years, the Funds paid the following brokerage
fees to USAA Brokerage Services, a discount brokerage service of the Adviser:

     aggregate  brokerage fees paid by the Growth and Income Fund, World Growth
     Fund,  Diversified Assets Fund, and Aggressive Growth Fund,  respectively,
     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
Assets Fund, and Aggressive  Growth Fund,  respectively,  were effected through
USAA Brokerage Services.

     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
and related commissions paid by these Funds were as follows:

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.

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:

     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

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).

                        PRINCIPAL HOLDERS OF SECURITIES

   
     As of January 31, 1999, USAA Life, either directly or through the Separate
Account,  owned of record  and  beneficially  the  percentages  of each  Fund's
outstanding shares as shown below.

                  Money Market Fund                         -
                  Income Fund                             50.02%
                  Growth and Income Fund                  18.30%
                  World Growth Fund                       35.41%
                  Diversified Assets Fund                 23.23%

                  International Fund                      93.36%
    

     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.

                  Income Fund                             49.98%
                  Growth and Income Fund                  81.70%
                  World Growth Fund                       64.59%
                  Diversified Assets Fund                 76.77%
                  Aggressive Growth Fund                  19.90%
                  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

                        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

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.

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.

                  APPENDIX B - COMPARISON OF FUND PERFORMANCE

     The Trust may make comparisons in advertising and sales literature between
the Funds  contained in this SAI and other  comparable  funds in the  industry.
These  comparisons  may  include  such  topics as risk and  reward,  investment
objectives, investment strategies, and performance.

     Fund  performance  also may be compared to the performance of broad groups
of  mutual  funds  with  similar  investment  goals  or  unmanaged  indexes  of
comparable  securities.  Evaluations  of Fund  performance  made by independent
sources  also may be used in  advertisements  concerning  the  Fund,  including
reprints of, or selections  from,  editorials or articles  about the Fund.  The

ITEM 24.  Persons Controlled by or Under Common Control with Registrant

     No person is controlled by Registrant.  All of the  outstanding  shares of
beneficial  interest of Registrant  are owned of record by USAA Life  Insurance
Company ("USAA Life"),  which is a wholly owned  subsidiary of United  Services
Automobile  Association  ("USAA"),  and  the  Separate  Account  and  the  Life
Insurance  Separate  Account  of USAA Life  Insurance  Company  (the  "Separate
Accounts"),  segregated  asset  accounts of USAA Life.  USAA Life  beneficially
owns,  both  directly  and through the Separate  Account,  more than 25% of the
shares of each of Registrant's Funds (other than the Money Market Fund), and as
a result,  may be deemed to control  (with the  exception  of the Money  Market
Fund) each Fund of the Registrant. Various companies affiliated with Registrant
may, therefore, be deemed to be under common control with each Fund (other than
the Money Market Fund) of the Registrant.


ITEM 25.  Indemnification
    

     Indemnification against liability is provided to the Trustees and officers
of the  Registrant,  the  underwriter  of the  Registrant,  and  the  following
affiliated persons of the Registrant, in the following ways:

     (a) Directors'  and Officers'  Liability  Policy:  The  Registrant and its
         Trustees and officers are covered  under a joint  liability  insurance
         policy  ("policy") along with USAA IMCO, other mutual funds managed by
         USAA IMCO, and USAA Shareholder  Account Services.  The policy insures
         against errors and omissions as described therein.

     (b) Indemnification  under the Master Trust Agreement,  as amended:  Under
         Article V of the  Registrant's  Master Trust  Agreement  (incorporated
         herein  by  reference  to  Exhibit  (1)  (b)(i)  of this  Registration
         Statement),  the Registrant has agreed to indemnify any Shareholder or
         former Shareholder,  and each of its Trustees and officers,  including
         persons serving at the Registrant's request as Directors,  officers or
         trustees  of  another  organization  in which the  Registrant  has any
         interest as a shareholder, creditor or otherwise, against liability as
         specified therein.

   
     (c) Indemnification  under  the  Amended  and  Restated  Underwriting  and
         Administrative Services Agreement:  Under Section 9 of the Amended and
         Restated  Underwriting and  Administrative  Services  Agreement by and
         between the Registrant,  USAA Life and USAA IMCO (incorporated  herein
         by reference to Exhibit (5) of this Registration Statement), USAA Life
         and USAA IMCO have agreed to indemnify the Registrant and one another,
         and each of the Trustees,  Directors and officers (or former Trustees,
         Directors and officers) of each party, and any person who controls any
         party, against liability as specified therein.

     (d) Indemnification  under the  Custodian  Agreement,  as  amended:  Under
         Section  2.12(6)  and  Section  8 of the  Custodian  Agreement  by and
         between the Registrant and State Street Bank and Trust Company ("State
         Street")  (incorporated  herein by reference to Exhibit (7)(a) of this
         Registration Statement),  State Street has agreed to be responsible to
         the Registrant for  negligence or  misconduct,  as specified  therein.
         Under  Section 9 of the  Amendment to the  Custodian  Agreement by and
         between  the  Registrant  and  State  Street  (incorporated  herein by
         reference  to  Exhibit  (7)(b) of this  Registration  Statement),  any
         foreign    banking    institution    employed    by   the    Custodian
         ("Sub-Custodian")  shall  indemnify  State Street and the  Registrant,
         against  liability  as  specified  therein.  Under  Section  10 of the
         Amendment to the Custodian  Agreement,  the Custodian has agreed to be
         liable for the acts or omissions of a foreign  banking  institution as
         specified therein.

     (e) Indemnification under the Transfer Agent Agreement,  as amended: Under
         Section 12 of the Transfer Agent Agreement  between the Registrant and
         USAA Life (incorporated  herein by reference to Exhibit (8)(a) of this
         Registration  Statement),  USAA  Life  has  agreed  to  indemnify  the
         Registrant against liability as specified therein,  and the Registrant
         shall indemnify USAA Life against liability as specified therein.
    

     (f) Indemnification  under the Distribution and Administration  Agreement,
         as amended:  Under Section 14 of the Distribution  and  Administration
         Agreement by and between USAA Life and USAA IMCO 

<PAGE>

         (incorporated  herein  by  reference  to  Exhibit  3 of  Pre-Effective
         Amendment No. 1 to the Form N-4 Registration Statement of the Separate
         Account, filed on December 22, 1994), USAA Life, on its own behalf and
         on behalf of the Separate Account,  has agreed to indemnify USAA IMCO,
         its agents,  employees and any person who controls USAA IMCO,  against
         liability as specified therein,  and USAA IMCO has agreed to indemnify
         USAA Life, its Directors and officers,  the Separate Account,  and any
         person who controls USAA Life, against liability as specified therein.

     (g) Indemnification under the Bylaws of USAA Life: Under Article IX of the
         Bylaws of USAA Life (incorporated  herein by reference to Exhibit 6(b)
         of the initial filing, on August 1, 1994, of the Form N-4 Registration
         Statement of the Separate Account),  USAA Life has agreed to indemnify
         any Director,  officer, former Director or former officer of USAA Life
         against liability as specified therein.

     (h) Indemnification  under the Delaware  Business Trust Act: Under Section
         3803(b)  of the  Delaware  Business  Trust  Act,  except to the extent
         otherwise provided in the governing  instrument of a business trust, a
         Trustee, when acting in such capacity, is not personally liable to any
         person  other than the business  trust or a  beneficial  owner for any
         act,  omission  or  obligation  of the  business  trust or any Trustee
         thereof.

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

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

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

         3.6 The Trust shall have the right to suspend  redemption of shares of
any Fund  pursuant to the  conditions  set forth in the  Prospectus.  The Trust
shall  also have the right to  suspend  the sale of shares of any or all of its
Funds at any time when it is authorized  to 

                                       4
<PAGE>

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

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

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

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

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

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

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

                                       5
<PAGE>

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

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

4.  LEGAL COMPLIANCE.

         4.1  TAX LAWS.

         (a) The Trust  represents  that it shall make every  effort to qualify
and to maintain  qualification of each Fund as a regulated  investment  company
("RIC")  under  Subchapter M of the Internal  Revenue Code of 1986,  as amended
(the  "Code"),  and the  Trust or the  Underwriter  shall  notify  the  Company
immediately upon having a reasonable basis for believing that a Fund has ceased
to so qualify or that it might not so qualify in the future.

         (b) The Company  represents that it believes,  in good faith, that the
Contracts and Policies will be treated,  respectively, as annuity contracts and
life  insurance  policies under  applicable  provisions of the Code and that it
will make every effort to maintain such treatment. The Company shall notify the
Trust  and the  Underwriter  immediately  upon  having a  reasonable  basis for
believing that any of the Contracts or Policies have ceased to be so treated or
that they might not be so treated in the future.

         (c) The Trust represents that it shall make every effort to comply and
to maintain each Fund's  compliance with the  diversification  requirements set
forth in Section 817(h) of the Code and Section  1.817-5(b) of the  regulations
under the Code,  and the Trust or the  Underwriter  shall  notify  the  Company
immediately upon having a reasonable basis for 

                                       6
<PAGE>

believing  that a Fund has  ceased  to so  comply  or that a Fund  might not so
comply in the future.

         (d) The Company represents that it believes,  in good faith, that each
Account is a "segregated  asset account" and that interests in each Account are
offered  exclusively  through  the  purchase  of or  transfer  into a "variable
contract,"  within the meaning of such terms under  Section  817(h) of the Code
and the regulations thereunder. The Company shall make every effort to continue
to meet such definitional  requirements,  and it shall notify the Trust and the
Underwriter  immediately upon having a reasonable basis for believing that such
requirements have ceased to be met or that they might not be met in the future.

         (e) The Trust  represents  that,  under  the  terms of its  investment
advisory  agreement with the  Underwriter,  which also serves as the investment

the Trust in compliance with the Trust's  investment  objectives,  policies and
restrictions  as set forth in the Prospectus.  The Trust  represents that these
objectives,  policies and restrictions do and shall include  operating as (i) a
RIC in compliance  with Subchapter M and (ii) in compliance with Section 817(h)
of the Code and  regulations  thereunder.  The  Trust  has  adopted  and  shall
maintain  procedures for ensuring that the Trust is managed in compliance  with
Subchapter M and Section 817(h) of the Code and the regulations thereunder.  On
request,  the Trust  shall  also  provide  the  Company  with  such  materials,
cooperation  and  assistance as may be reasonably  necessary for the Company or
any person designated by the Company to review from time to time the procedures
and  practices  of the  Underwriter,  or any other  provider of services to the
Trust for ensuring  that the Trust is managed in compliance  with  Subchapter M
and Section 817(h) of the Code and the regulations thereunder.

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

                                       7
<PAGE>

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

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

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

9. INDEMNIFICATION.

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

                                      20
<PAGE>

statement,  Prospectus,  or annual or interim reports to Shareholders,  (2) any
omission or alleged  omission to state a material fact in connection  with such
information  furnished by the  Underwriter to the Trust which is required to be
stated in any of such  documents  or  necessary  to make such  information  not
misleading,  (3) any misrepresentation or omission or alleged misrepresentation
or  omission  to state a material  fact on the part of the  Underwriter  or any
agent or employee  of the  Underwriter  or any other  person for whose acts the
Underwriter  is  responsible,  unless  such  misrepresentation  or  omission or
alleged  misrepresentation  or omission  was made in  reliance  on  information
furnished by the Trust,  or (4) the willful  misconduct  or failure to exercise
reasonable  care and diligence on the part of the  Underwriter  or any agent or
employee of the  Underwriter or any other person for whose acts the Underwriter
is responsible  with respect to services  rendered under this  Agreement.  This
indemnity  provision,  however,  shall not  operate to protect  any  officer or
Trustee  of the Trust from any  liability  to the Trust or any  shareholder  by
reason  of  willful  misfeasance,  bad  faith,  gross  negligence  or  reckless
disregard of his or her duties.

         In case any  action  shall be  brought  against  any  Indemnitee,  the
Underwriter shall not be liable under its indemnity agreement contained in this
paragraph  with  respect to any claim made against any  Indemnitee,  unless the
Indemnitee  shall have notified the  Underwriter in writing within a reasonable
time after the summons or other first legal process  giving  information of the
nature of the claim shall have been served  upon the  Indemnitee  (or after the
Indemnitee shall have received notice of such service on any designated agent),
but  failure to notify the  Underwriter  of any such claim shall not relieve it
from liability to the Indemnitees against whom such action is brought otherwise
than on account of this  Section  9.1.  The  Underwriter  will be  entitled  to
participate at its own expense in the defense,  or, if it so elects,  to assume
the  defense  of any suit  brought to enforce  any such  liability,  but if the
Underwriter  elects to assume the defense,  such defense  shall be conducted by
counsel chosen by it and  satisfactory to the Indemnitees  which are defendants
in the suit. In the event the  

                                      21
<PAGE>

Underwriter  elects to assume  the  defense  of any such suit and  retain  such
counsel,  the Indemnitees  which are defendants in the suit shall bear the fees
and  expenses of any  additional  counsel  retained  by them,  but, in case the
Underwriter  does not  elect to  assume  the  defense  of any  such  suit,  the
Underwriter will reimburse the Indemnitees which are defendants in the suit for
the  reasonable  fees  and  expenses  of any  counsel  retained  by  them.  The
Underwriter shall promptly notify the Trust and the Company of the commencement
of any litigation or  proceedings  in connection  with the issuance or sales of
the shares.

         9.2 The Company  shall  indemnify  and hold harmless the Trust and the
Underwriter  and each of their  Trustees,  directors  and  officers  (or former
Trustees,  directors and  officers)  and each person,  if any, who controls the
Trust or the  Underwriter  within  the  meaning  of  Section 15 of the 1933 Act
(collectively,  "Indemnitees")  against any loss, liability,  claim, damage, or
expense  (including the reasonable cost of investigating  and defending against
the same and any counsel  fees  reasonably  incurred in  connection  therewith)
incurred by any Indemnitees under the 1933 Act or under common law or otherwise
which arise out of or are based upon (1) any untrue or alleged untrue statement
of a material fact contained in  information  furnished to the Trust for use in
the Trust's registration statement, Prospectus, or annual or interim reports to
Shareholders,  (2) any omission or alleged omission to state a material fact in
connection with such  information  furnished by the Company to the Trust or the
Underwriter,  which  is  required  to be  stated  in any of such  documents  or
necessary to make such information not misleading, (3) any misrepresentation or
omission or alleged  misrepresentation  or omission to state a material fact on
the part of the  Company or any agent or  employee  of the Company or any other
person for whose acts the Company is responsible, unless such misrepresentation
or omission or alleged  misrepresentation  or omission  was made in reliance on
information  furnished  by the  Trust or the  Underwriter,  or (4) the  willful
misconduct or failure to exercise  reasonable care and diligence on the part of
the Company or any agent or  employee  of the  Company or any other  person for
whose acts the Company is 

                                      22
<PAGE>

responsible  with  respect to  services  rendered  under this  Agreement.  This
indemnity provision,  however,  shall not operate to protect the Underwriter or
any  officer or Trustee  of the Trust  from any  liability  to the Trust or any
shareholder by reason of willful  misfeasance,  bad faith,  gross negligence or
reckless disregard of their duties.

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

         In case any  action  shall be  brought  against  any  Indemnitee,  the
Company  shall not be liable under its  indemnity  agreement  contained in this
paragraph  with  respect to any claim made against any  Indemnitee,  unless the
Indemnitee  shall have notified the Company in writing within a reasonable time
after the summons or other first legal process giving information of the nature
of the  claim  shall  have  been  served  upon the  Indemnitee  (or  after  the
Indemnitee shall have received notice of such service on any designated agent),
but  failure to notify the  Company of any such claim shall not relieve it from
liability to the Indemnitees against whom such action is brought otherwise than
on account of this Section 9.2. The Company will be entitled to  participate at
its own expense in the defense,  or, if it so elects,  to assume the defense of
any suit brought to enforce any such  liability,  but if the Company  elects to
assume the defense, such defense shall be conducted by counsel chosen 

                                      23
<PAGE>

by it and satisfactory to the Indemnitees  which are defendants in the suit. In
the event the  Underwriter  elects to assume  the  defense of any such suit and
retain such counsel,  the  Indemnitees  which are  defendants in the suit shall
bear the fees and expenses of any additional  counsel retained by them, but, in
case the  Company  does not elect to assume the  defense of any such suit,  the
Company will reimburse the Indemnitees  that are defendants in the suit for the
reasonable fees and expenses of any counsel retained by them. The Company shall
promptly  notify  the  Trust and the  Underwriter  of the  commencement  of any
litigation  or  proceedings  in  connection  with the  issuance or sales of the
shares.

10.  REGULATORY REPORTS.

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

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

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

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

11.  DURATION AND TERMINATION OF AGREEMENT.

         11.1 This Agreement  shall become  effective as of January 1, 1999 and
shall remain in force until January 1, 2001 and thereafter, but only so long as
such continuance is specifically approved at least annually by (i) the Board of
Trustees,  or by the vote of a 

                                      24

majority of the outstanding  voting  securities of the Trust, cast in person or
by proxy,  and (ii) a majority  of those  Trustees  who are not parties to this
Agreement or  interested  persons of any such party cast in person at a meeting

foregoing,  the  Board of  Trustees  may,  from time to time,  establish  a new
effective  date for the  continuance  of this  Agreement  with  respect  to any
initial Fund and/or  additional  Fund;  PROVIDED,  that such new effective date
precedes the then current termination date of the Agreement.

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

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

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

13.  CONFIDENTIALITY.

         Neither  the  Company nor the  Underwriter  shall  disclose or use any
records or information  obtained  hereunder in any manner  whatsoever except as
expressly authorized  

                                      25

         The Trust,  Underwriter  and Company  represent  and warrant that each
will fully  coordinate  and  cooperate  with each other in assuring  compliance
under this Agreement with all federal and state laws and regulations.

Investment  Trust (the "Trust"),  a business trust organized and existing under
the laws of the State of Delaware,  having its  principal  place of business at
9800 Fredericksburg  Road, San Antonio,  Texas 78288, and State Street Bank and
Trust Company (the  "Custodian"),  a  Massachusetts  trust company,  having its
principal  place of  business at 225  Franklin  Street,  Boston,  Massachusetts
02110.

                                  WITNESSETH:

         WHEREAS,  the Trust is authorized  to issue shares in separate  Funds,
with  each  such  Fund  representing  interests  in  a  separate  portfolio  of
securities and other assets; and

         WHEREAS,  the Trust  intends to initially  offer shares in five Funds:
USAA Life Money Market Fund, USAA Life Income Fund, USAA Life Growth and Income
Fund, USAA Life World Growth Fund, and USAA Life  Diversified  Assets Fund (the
"Fund" or  "Funds")  such  Funds  together  with all other  Funds  subsequently
established by the Trust and made subject to this Agreement in accordance  with
Article 12.

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

1.       Employment of Custodian and Property To Be Held by It

         The Trust hereby  employs the Custodian as the custodian of the assets
of the  Funds of the Trust  pursuant  to the  provisions  of the  Master  Trust
Agreement (the "Trust  Agreement").  The Trust on behalf of the Funds agrees to
deliver to the  Custodian  all assets,  including  securities  and cash, of the
Funds,   and  all  payments  of  income,   payments  of  principal  or  capital
distributions  received by it with respect to all securities owned by the Funds
from time to time,  and the cash  consideration  received by it for such new or
treasury shares of beneficial  interest of the Trust representing  interests in
the Funds,  as may be issued or sold from time to time. The Custodian shall not
be responsible  for any property of the Funds held or received by the Trust and
not delivered to the Custodian.

         Upon receipt of "Proper  Instructions"  (within the meaning of Section
2.17),  the Custodian shall on behalf of the applicable Fund or Funds from time
to time employ one or more sub-custodians, but only in accordance with and upon
receipt of certified  copy of an approving  resolution of the Board of Trustees
of the Trust on behalf of the applicable  Fund or Funds,  and provided that the
Custodian shall have no more or less  responsibility  or liability to the Trust
on account of any actions or omissions of any subcustodian so employed than any
such sub-custodian has to the Custodian.

                  used in  accordance  with Rule  17f-3  under  the  Investment
                  Company  Act of 1940  (The  "1940  Act").  Funds  held by the
                  Custodian  for a Fund may be deposited by it to its credit as
                  Custodian in the Banking  Department  of the  Custodian or in
                  such  other  banks  or  trust  companies  as it  may  in  its
                  discretion  deem necessary or desirable;  provided,  however,
                  that every such bank or trust  company  shall be qualified to
                  act as a custodian under The 1940 Act and that each such bank
                  or trust company and the funds to be deposited with each such
                  bank or trust company shall on behalf of each applicable Fund
                  be approved by vote of a majority of the Board of Trustees of
                  the Trust.  Such funds shall be deposited by the Custodian in
                  its capacity as Custodian  and shall be  withdrawable  by the
                  Custodian only in that capacity.

         2.5      Payments for Shares.  The  Custodian  shall  receive from the
                  applicable  separate  account of USAA Life Insurance  Company

                  deposit  into  the  account  of  the  appropriate  Fund  such
                  payments  for shares of that Fund issued or sold from time to
                  time by the Trust.  USAA Life or a third party  administrator
                  on its behalf  shall  cause such  payments  to be made to the
                  Custodian.  The Custodian will provide timely notification to
                  the Trust and the Trust's Transfer Agent of any receipt by it
                  of payments  for shares of such Funds and the identity of the
                  fund to which each such payment relates.

                  the  Trust  on  behalf  of  each   applicable  Fund  and  the
                  Custodian,  the Custodian  shall,  upon die receipt of Proper
                  Instructions from the Trust on behalf of a Fund, make federal
                  funds  available  to such Fund as of  specified  times agreed
                  upon from time to time by the Trust and the  Custodian in the

                  which are deposited into the Fund's account.

                  and other payments with respect to registered securities held
                  hereunder to which each Fund shall be entitled  either by law
                  or pursuant to custom in the securities  business,  and shall
                  collect on a timely basis all income and other  payments with
                  respect  to bearer  securities  if, on the date of payment by
                  the issuer,  such securities are held by the Custodian or its
                  agent,  or are held in a  Securities  System  on such date of
                  payment, and shall credit such income, as collected,  to such
                  Fund's custodian account.  Without limiting the generality of
                  the  foregoing,  the  Custodian  shall detach and present for
                  payment  all  coupons  and  other  income   items   requiring
                  presentation  as and when they  become due and shall  collect
                  interest when due on securities  held  hereunder.  Income due
                  each Fund on securities  loaned pursuant to the provisions of
                  Section  2.2 (10) shall be the  responsibility  of the Trust.
                  The  Custodian  will  have  no  duty  or   responsibility  in
                  connection  therewith,  other than to provide  the Trust with
                  such  information  or data as may be  necessary to assist the

                  continuing   instructions  when  deemed  appropriate  by  the
                  parties,  the Custodian shall pay out monies of a Fund in the

                           to its duties under this Contract, provided that all
                           such payments shall be accounted for to the Trust on

                 by it to be genuine and to have been  properly  executed by an
                 authorized  person by or on behalf of the Trust. The Custodian

                  connection with the initial  approval of this  Agreement.  In
                  addition, the Custodian will promptly inform the Trust in the
                  event  of  any  material  adverse  change  in  its  financial
                  condition or any material loss of the assets of the Trust.

         so, shall advise the TPA for the Separate Account  periodically of the
         division  of  such  net  income  among  its  various  components.  The
         calculations  of the net asset value per share and the daily income of
         each Fund  shall be made at the time or times  described  from time to
         time in the  Fund's  currently  effective  prospectus  related to such
         Fund.

         4.       Records

                  The  Custodian  shall with  respect  to each Fund  create and
         maintain all records relating to its activities and obligations  under
         this  Agreement  in such  manner as will meet the  obligations  of the
         Trust  under the 1940 Act,  with  particular  attention  to Section 31
         thereof and Rules 31a-1 and 3 la-2 thereunder.  All such records shall

         authorized  Officers,  employees or agents of the Trust and  employees
         and agents of the  Commission.  The  Custodian  shall,  at the Trust's
         request,  supply the Trust with a tabulation  of  securities  owned by
         each Fund and held by the Custodian and shall, when requested to do so
         by the Trust and for such compensation as shall be agreed upon between
         the Trust  and the  Custodian,  include  certificate  numbers  in such
         tabulations  or  provide  such  other  information  as the  Trust  may
         reasonably request.

         5.       Opinion of Trust's Independent Public Accountants

         Fund  may from  time to time  request,  to  obtain  from  year to year
         favorable  opinions  from the  Trust's  independent  accountants  with
         respect to its activities hereunder in connection with the preparation
         of the Trust's Form N-lA and Form N-SAR or other annual reports to the
         Commission  and  with  respect  to  any  other  requirements  of  such
         Commission.

         6.       Reports to Trust by Independent Public Accountants

                  The Custodian  shall provide the Trust,  on behalf of each of
         the  Funds at such  times as the Trust may  reasonably  require,  with
         reports by the Custodian or by independent  public  accountants on the
         accounting  system,  internal  accounting  control and  procedures for
         safeguarding  securities,  futures  contracts  and  options  on future
         contracts,  including  securities  deposited  and/or  maintained  in a
         Securities System,  relating to the services provided by the Custodian
         under this Agreement; such reports shall be of sufficient scope and in
         sufficient  detail,  as may  reasonably  be  required  by the Trust to
         provide reasonable  assurance that any material  inadequacies would be
         disclosed by such examination, and, if there are no such inadequacies,
         the report shall so state.

         7.       Compensation of Custodian

                  The Custodian  shall be entitled to  reasonable  compensation
         for its services and expenses as Custodian,  as agreed upon in writing

         and the Custodian.

         8.       Responsibility of Custodian

                  So long as and to the extent  that it is in the  exercise  of
         reasonable care; the Custodian shall not be responsible for the title,
         validity or  genuineness  of any property or evidence of title thereto
         received by it or delivered by it pursuant to this Agreement and shall
         be  held  harmless  in  acting  upon  any  notice,  request,  consent,
         certificate  or  other  instrument  reasonably  believed  by  it to be
         genuine and to be signed by the proper party or parties, including any
         future  commission   merchant  acting  pursuant  to  the  terms  of  a
         three-party future or options agreement.  Notwithstanding  anything to
         the  contrary  elsewhere in this  Agreement,  the  Custodian  shall be
         responsible for all damages and expenses actually incurred as a result
         of the negligent action,  negligent inaction, or willful misconduct of
         the  Custodian,  any agent  appointed  by the  Custodian  pursuant  to
         Section  2.11,  or  any  of  their  officers,   agents,  nominees,  or
         employees,  in the performance of any function  hereunder,  including,
         without   limitation,   reasonable  attorney  fees  and  investigation
         expenses;  but the  Custodian  shall be  indemnified  by and  shall be
         without  liability  to the Trust for any action taken or omitted by it
         in good faith without negligence.  It shall be entitled to rely on and
         may act upon advice of counsel reasonably acceptable to the Trust (who
         may be  counsel  for the Trust) on all  matters,  and shall be without
         liability for any action  reasonably taken or omitted pursuant to such
         advice.

                  If the Trust on behalf of a Fund  requires  the  Custodian to
         take any action with respect to securities,  which action involves the
         payment of money or which action may, in the opinion of the Custodian,
         result in the  Custodian  or its nominee  assigned to the Trust or the
         Funds being liable for the payment of money or incurring  liability of
         some other form, the Trust on behalf

                                      27
<PAGE>

         of the Funds,  as a  prerequisite  to requiring  the Custodian to take
         such action, shall provide indemnity to the Custodian in an amount and
         form satisfactory to it.

                  If  the  Trust  requires  the  Custodian,   its   affiliates,
         subsidiaries or agents,  to advance cash or securities for any purpose
         (including but not limited to securities settlements, foreign exchange
         contracts and assumes  settlement) for the benefit of a Fund or in the
         event that the Custodian or its nominee shall incur or be assessed any
         taxes,   charges,   expenses,   assessments,   claims  or  liabilities
         (excluding  the  Custodian's  operating  overhead  and  taxes  arising
         generally  out of the  Custodian's  business) in  connection  with the
         performance  of this  Agreement,  except such as may arise from its or
         its officers',  employees', agent's or nominee's own negligent action,
         negligent  failure to act or willful  misconduct,  any property at any
         time held for the  account of the  applicable  Fund shall be  security
         therefore and should the Trust fail to repay the  Custodian  promptly,
         the  Custodian  shall be  entitled  to utilize  available  cash and to
         dispose  of such  Fund's  assets  to the  extent  necessary  to obtain
         reimbursement.

         9.       Effective Period, Termination and Amendment

                  This  Agreement  shall become  effective as of its execution,
         shall   continue  in  full  force  and  effect  until   terminated  as
         hereinafter  provided,  may be amended at any time by mutual agreement
         of the  parties  hereto and may be  terminated  by either  party by an
         instrument m writing  delivered or mailed by registered mail,  postage
         prepaid to the other party, such termination to take effect not sooner

         however, that the Custodian shall not with respect to a Fund act under
         Section 2.12

                                      28
<PAGE>

         hereof in the  absence of receipt  of an  initial  certificate  of the
         Secretary or Assistant  Secretaries  that the Board of Trustees of the
         Trust has approved the initial use of a particular  Securities  System
         by such Fund as  required  in each case by Rule  17f-4  under The 1940
         Act, as amended,  and that the  Custodian  shall not with respect to a
         Fund act under  Section  2.12A  hereof in the absence of receipt of an
         initial certificate of the Secretary or Assistant Secretaries that the
         Board of Trustees  has  approved  the initial use of the Direct  Paper
         System by such Fund; provided further,  however,  that the Trust shall
         not  amend  or  terminate  this  Agreement  in  contravention  of  any
         applicable federal or state regulations, or any provision of the Trust
         Agreement,  and further  provided,  that the Trust on behalf of one of
         more  of the  Funds  may be at any  time by  action  of its  Board  of
         Trustees  (i)  substitute  another  bank  or  trust  company  for  the
         Custodian by giving  notice as described  above to the  Custodian,  or
         (ii)  immediately  terminate  this  Agreement  in  the  event  of  the
         appointment  of a  conservator  or receiver  for the  Custodian by the
         Comptroller  of the Currency or upon the  happening of a like event at
         the  direction  of  an  appropriate  regulatory  agency  or  court  of
         competent jurisdiction.

                  Upon  termination  of the  Agreement,  the Trust on behalf of
         each applicable  Fund shall pay to the Custodian such  compensation as
         may be due as of the  date  of such  termination  and  shall  Likewise
         reimburse the Custodian for its costs,  expenses and  disbursements in
         discharging its responsibilities hereunder,  excluding the Custodian's
         operating overhead.

         10.      Successor Custodian

         If a  successor  custodian  for the  Trust or one or more of the Funds
shall be appointed by

                                      29
<PAGE>

         the  Board  of  trustees  of the  Trust,  the  Custodian  shall,  upon
         termination,  deliver to such successor custodian at the office of the
         Custodian,  duly endorsed and in the form for transfer, all securities
         or other assets of each applicable Fund then held by it its agents, or
         subcustodians hereunder, shall transfer to an account of the successor
         custodian or subcustodian all of the securities of each such Fund held
         in a  Securities  System,  and  shall  cause  all  securities  held by
         sub-custodians  to be  transferred  to the  accounts of the  successor
         custodian  or its  sub-custodians,  as  the  successor  custodian  may
         direct.

               If no such successor custodian shall he appointed, the Custodian
         shall,  in like manner,  upon receipt of a certified copy of a vote of
         the Board of  Trustees  of the  Trust,  deliver  at the  office of the
         Custodian and transfer such securities,  funds and other properties in
         accordance with such vote.

               In the event  that no  written  order  designating  a  successor
         custodian or certified  copy of a vote of the Board of Trustees  shall
         have been  delivered to the  Custodian on or before the date when such
         termination shall become effective,  then the Custodian shall have the
         right to  deliver  to a bank or trust  company,  which is a "bank"  as
         defined in the 1940 Act, doing business in Boston,  Massachusetts,  of
         its own selection, having an aggregate capital, surplus, and undivided
         profits,  as shown  by its last  published  report,  of not less  than
         $25,000,000,  all securities,  funds and other  properties held by the
         Custodian on behalf of each applicable  Fund and all instruments  held
         by the Custodian  relative  thereto and all other  property held by it
         under  this  Agreement,  on  behalf  of each  applicable  Fund  and to
         transfer to an account of such successor custodian all of

                                      30
<PAGE>

         the  securities  of each  such  Fund  held in any  Securities  System.
         Thereafter,  such bank or trust  company shall be the successor of the
         Custodian under this Agreement.

                  In the event  that  securities,  funds  and other  properties
         remain  in the  possession  of the  Custodian,  or in the  Custodian's
         account with a Securities System, after the date of termination hereof
         owing to  failure of the Trust to procure  the  certified  copy of the
         vote  referred  to or of the Board of  Trustees to appoint a successor
         custodian,  the Custodian shall be entitled to fair  compensation  for
         its services during such period as the Custodian retains possession of
         such securities, funds and other properties and the provisions of this
         Agreement  relating  to the duties and  obligations  of the  Custodian
         shall remain in full force and effect.

         11.      Interpretive and Additional Provisions

                  In  connection  with the  operation  of this  Agreement,  the
         Custodian and the Trust on behalf of each of the Funds,  may from time
         to time agree on such provisions interpretive of or in addition to the
         provisions  of  this  Agreement  as  may in  their  joint  opinion  be
         consistent  with  the  general  tenor  of  this  Agreement.  Any  such
         interpretive  or additional  provisions  shall be in writing signed by
         both  parties  and  shall be  annexed  hereto,  provided  that no such
         interpretive or additional  provisions shall contravene any applicable
         federal or state  regulations or any provision of the Trust Agreement.
         No  interpretive  or  additional  provisions  made as  provided in the
         preceding  sentence  shall  be  deemed  to be  an  amendment  of  this
         Agreement.

         to which it desires to have the Custodian render services as Custodian
         under the terms  hereof,  it shall so notify the Custodian in writing,
         and if the Custodian agrees in writing to provide such services,  such
         series of shares shall become a Fund hereunder.

         13.      Massachusetts Law To Apply

         This  Agreement   shall  be  construed  and  the  provisions   thereof
         interpreted  under and in accordance with laws of the  Commonwealth of
         Massachusetts.

         14.      Prior Agreements

                  This  Agreement  supersedes  and  terminates,  as of the date
         hereof,  all prior  Agreements  between the Trust on behalf of each of
         the Funds and the  Custodian  relating  to the  custody of the Trust's
         assets.

      WHEREAS, the Custodian and the Trust are parties to a Custodian Agreement

foreign banking  institutions  and foreign  securities  depositories  acting as
sub-custodians  in  conformity  with  the  requirements  of  Rule  17f-5  under
Investment Company Act of 1940 (the "1940 Act");

      NOW THEREFORE,  in consideration of the premises and covenants  contained
herein,  the Custodian and the Trust hereby amend the Agreement by the addition
of the following terms conditions:

                                       1
<PAGE>

         1.       Appointment of Foreign Sub-Custodians

          The Trust hereby  authorizes and instructs the Custodian to employ as
subcustodians for the Trust's  securities and other assets  maintained  outside
the United  States the foreign  banking  institutions  and  foreign  securities
depositories  specifically  approved  by the  Trust's  Board  of  Trustees  and
authorized  by the  Trust's  Board of  Trustees,  as  evidenced  by a certified
resolution to be designated  on Schedule A hereto  ("foreign  sub-custodians").
Upon  receipt of  "Proper  Instructions",  as  defined  in Section  2.17 of the
Agreement,  together  with a  certified  resolution  of the  Trust's  Board  of
Trustees, the Custodian and the Trust may agree to amend Schedule A hereto from
time to time to designate  additional foreign banking  institutions and foreign
securities  depositories  to act  as  sub-custodians.  By  delivery  of  Proper
Instructions,  the Trust may instruct the Custodian to cease the  employment of
any one or more of such  sub-custodians for maintaining  custody of the Trust's
assets.

         2.       Assets To Be Held

          The Custodian shall limit the securities and other assets  maintained
in the custody of the foreign  sub-custodians to: (a) "foreign securities",  as
defined in paragraph (c)(1) of Rule

                                       2
<PAGE>

17f-5 under the 1940 Act, and (b) cash and cash  equivalents in such amounts as
the Custodian or the Trust may  determine to be reasonably  necessary to effect
the Trust's  foreign  securities  transactions.  The Custodian shall cause cash
held by foreign  sub-custodians  to be in  interest  bearing  accounts,  to the
extent practicable.

         3.       Foreign Securities Depositories

                  Except as may  otherwise  be agreed  upon in  writing  by the
Custodian  and the Trust,  assets of the Trust shall be  maintained  in foreign
securities  depositories only through  arrangements  implemented by the foreign
banking  institutions  serving as sub-custodians  pursuant to the terms hereof.
Where  possible,   such  arrangements   shall  include  entry  into  agreements
containing the provisions set forth in Section 5 hereof.

         4.       Segregation of Securities

                  The  Custodian  shall  identify on its books as  belonging to
each applicable Fund of the Trust, the foreign  securities of such Fund held by
each foreign  sub-custodian.  Each  agreement  pursuant to which the  Custodian
employs a foreign banking institution shall require

<PAGE>

that such  institution  establish a custody account for the Custodian on behalf
of the Trust for each applicable Fund and physically segregate in that account,
securities  and  other  assets  of  the  Trust,  and  in the  event  that  such
institution deposits the Trust's securities in a foreign securities depository,
that it shall identify on its books as belonging to the Custodian, as agent for
the Trust, the securities so deposited.

         5.       Agreements with Foreign Banking Institutions

                  Each agreement with a foreign  banking  institution  shall be
substantially in the form set forth in Exhibit 1 hereto and shall provide that:
(a) the  Trust's  assets  will not be subject to any  right,  charge,  security
interest, lien or claim of any kind in favor of the foreign banking institution
or its creditors or agents, except a claim of payment for their safe custody or
administration;  (b) beneficial ownership for the Trust's assets will be freely
transferable  without  the  payment of money or value other than for custody or
administration;  (c) adequate records will be maintained identifying the assets
as belonging to each applicable Fund of the Trust;  (d) officers of or auditors
employed by, or other representatives of the Custodian, including to the extent
permitted  under  applicable law the  independent  public  accountants  for the
Trust,  will be given  access to the books and records of the  foreign  banking
institution relating

                                       4
<PAGE>

to its actions under its agreement  with the  Custodian;  and (e) assets of the
Trust  held  by  the  foreign   sub-custodian  will  be  subject  only  to  the
instructions of the Custodian or its agents. The procedures  established by the
Custodian for giving  "Instructions" (as defined in its agreements with foreign
sub-custodians)  to  foreign  sub-custodians  shall  provide  that the  foreign
sub-custodian  may rely  only on  instructions  that bear the  signature  of an
authorized person or are accompanied by an appropriate  identification  code or
test key  established  by the  Custodian  and the  foreign  sub-custodian.  Any
instructions  given otherwise than in hard copy form will be promptly confirmed
by  duplicate  hard  copy  instructions  from  the  Custodian  to  the  foreign
sub-custodian.

         6.       Access of Independent Accountants of the Trust

                  Upon request of the Trust,  the  Custodian  will use its best
efforts to arrange for the  independent  public  accountants of the Trust to be
afforded  access to the books and  records of any foreign  banking  institution
employed as a foreign sub-custodian insofar as such books and records relate to
the  performance of such foreign banking  institution  under its agreement with
the Custodian.

                                      5
<PAGE>

         7.       Reports by Custodian

                  The Custodian  will supply to the Trust from time to time, as
mutually agreed upon,  statements in respect of the securities and other assets
of the Trust held by foreign  sub-custodians,  including  but not limited to an
identification  of entities  having  possession of each Fund's  securities  and
other assets and advices or  notifications of any transfers of securities to or
from each custodial account maintained by a foreign banking institution for the
Custodian  on behalf  of each  applicable  Fund  indicating,  as to  securities
acquired for a Fund, the identity of the entity having  physical  possession of
such securities.


         8.       Transactions in Foreign Custody Account

                  (a) Except as  otherwise  provided in  paragraph  (b) of this
Section 8, the provisions of Section 2.2 and 2.8 of the Agreement  shall apply,
mutatis mutandis to the foreign securities of the Trust held outside the United
States by foreign sub-custodians.

                  (b)  Notwithstanding  any  provision of the  Agreement to the
contrary,

                                       6
<PAGE>

settlement and payment for securities received for the account of the Trust and
delivery of securities  maintained for the account of the Trust may be effected
in accordance with the customary  established  securities trading or securities
processing  practices and procedures in the jurisdiction or market in which the
transaction occurs, including, without limitation, delivering securities to the
purchaser  thereof or to a dealer  therefor (or an agent for such  purchaser or
dealer)  against a receipt with the reasonable  expectation of receiving  later
payment for such securities from such purchaser or dealer.

                  (c)  Securities  maintained  in  the  custody  of  a  foreign
sub-custodian  may be maintained  in the name of such  entity's  nominee to the
same extent as set forth in Section 2.3 of the Agreement,  and the Trust agrees
to hold any such nominee harmless from any liability  arising solely out of its
status as a holder of record of such  securities,  provided that such liability
did not result from the  negligence  or willful  misconduct  of the  Custodian,
sub-custodian, nominee, or any of their officers, employees or agents.

         9.       Liability of Foreign Sub-Custodians

                  Each  agreement  pursuant  to which the  Custodian  employs a
foreign banking

                                       7
<PAGE>

institution as foreign  sub-custodian shall require the institution to exercise
reasonable  care in the  performance  of its duties and to indemnify,  and hold
harmless,  the Custodian and the Trust from and against any loss, damage, cost,
expense,  liability  or  claim  arising  out  of  or  in  connection  with  the
institution's performance of such obligations. At the election of the Trust, it
shall be entitled to be subrogated to the rights of the Custodian  with respect
to any claims  against a foreign  banking  institution  or  foreign  securities
depository  or guaranty or insurance  fund as a  consequence  of any such loss,
damage,  cost, expense,  liability or claim if and to the extent that the Trust
has not been made whole for any such loss, damage, cost, expense,  liability or
claim.

         10.      Liability of Custodian

                  The Custodian  shall be liable for the acts or omissions of a
foreign banking institution or foreign securities depository to the same extent
as set forth with respect to sub-  custodians  generally in the Agreement  and,
regardless of whether assets are maintained in the custody of a foreign banking
institution,  a foreign  securities  depository  or a branch of a U.S.  bank as
contemplated  by Section 13 hereof,  the Custodian  shall not be liable for any
loss, damage, cost, expense, liability or claim resulting from nationalization,
expropriation,  currency restrictions,  or acts of war or terrorism or any loss
where   the   sub-custodian   has   otherwise   exercised    reasonable   care.
Notwithstanding the foregoing provisions of this Section 10, in

                                       8
<PAGE>

delegating  custody duties to State Street London Ltd., the Custodian shall not
be  relieved  of any  responsibility  to the  Trust  for any  loss  due to such
delegation,  except such loss as may result from (a) political risk (including,
but not limited to, exchange control restrictions, confiscation, expropriation,
nationalization,  insurrection, civil strife or armed hostilities) or (b) other
losses  (excluding a bankruptcy  or  insolvency of State Street London Ltd. not
caused by political risk) due to Acts of God,  nuclear incident or other losses
under  circumstances  where the  Custodian  and State Street  London Ltd.  have
exercised reasonable care.

         11.      Reimbursement for Advances

                  If the  Trust  requires  the  Custodian  to  advance  cash or
securities  for any purpose for the benefit of a Fund including the purchase or
sale of foreign exchange or of contracts for foreign exchange,  or in the event
that the  Custodian  or its  nominee  shall  incur or be  assessed  any  taxes,
charges, expenses,  assessments, claims or liability (excluding the Custodian's
operating  overhead  and taxes  arising  generally  out of the  conduct  of the
Custodian's  business) in connection  with the  performance of this  Agreement,
except  such as may arise  from its or its  officers',  employees',  agent's or
nominee's own negligent action, negligent failure to act or willful misconduct,
any property at any time held for the account of the applicable Fund shall

                                       9
<PAGE>

be  security  therefore  and  should  the  Trust  fall to repay  the  Custodian
promptly,  the  Custodian  shall be entitled to utilize  available  cash and to
dispose of such Fund's assets to the extent necessary to obtain reimbursement.

         12.      Monitoring Responsibilities

                  The Custodian shall furnish annually to the Trust, during the
month of June, information  concerning the foreign  sub-custodians  employed by
the Custodian,  which shall include  information  concerning  what insurance or
bonding  coverage  is  applicable  to  the  Trust's  foreign  securities.  Such
information  shall be similar in kind and scope to that  furnished to the Trust
in connection with the initial approval of this amendment to the Agreement.  In
addition,  the Custodian  will promptly  inform the Trust in the event that the
Custodian learns of a material  adverse change in the financial  condition of a
foreign sub-custodian or any material loss of the assets of the Trust or in the
case of any foreign  sub-custodian  not the subject of an exemptive  order from
the   Securities   and  Exchange   Commission   if  notified  by  such  foreign
sub-custodian  that  there  appears  to be a  substantial  likelihood  that its
shareholders'  equity will  decline  below $200  million  (U.S.  dollars or the
equivalent  thereof) or that its  shareholders'  equity has declined below $200
million (in each case computed in accordance with generally accepted U.S.

                                       10

<PAGE>

accounting principles).

         The  Custodian  shall  use its  best  efforts  to cause  each  foreign
sub-custodian to:

         (i) take such steps as may be necessary to secure or otherwise prevent
the loss of rights  attached to or  otherwise  relating to the Trust's  foreign
securities;

         (ii) collect  dividend,  interest and other income  payments  made and
stock dividends,  rights and similar  securities paid or issued with respect to
the Trust's  foreign  securities and collect and hold all such payments,  stock
dividends, rights and similar items for the account of the Trust;

         (iii)  present for payment the  Trust's  foreign  securities  that are
called,  redeemed,  or retired or otherwise  become payable and all coupons and
other income items that call for payment upon presentation and hold the amounts
received for the account of the Trust;

         (iv) execute such ownership and other  certificates as may be required
to obtain payment in respect of the Trust's foreign securities; and

                                       11
<PAGE>

         (v) exchange interim receipts or temporary  securities for the Trust's
foreign securities for definitive securities.

The  Custodian  shall  promptly  notify the Trust if it becomes  aware that any
foreign  sub-custodian  has failed or is  failing to take any of the  foregoing
actions,  or has  attempted  but  unsuccessfully  to take any of the  foregoing
actions.

         The Custodian shall also promptly notify the Trust if it becomes aware
of any  failure  of a  foreign  sub-custodian  to  fulfill  any  of  its  other
obligations  under its agreement with the  Custodian,  any  circumstances  that
might cause the continued  use of a foreign  sub-custodian  to be  inconsistent
with the  requirements  of Rule 17f-5  under the 1940 Act or with any action of
the  Trust's  Board  of  Trustees  in  connection   therewith,   of  any  other
circumstances  or  information  of which the Custodian  becomes aware and which
might materially  increase the risk of loss to the Trust of continuing to use a
sub-custodian or continuing to maintain assets in a foreign country.

         The  Custodian  shall  promptly  furnish  the Trust with a copy of any
reports   received   by  the   Custodian   in   connection   with  any  foreign
sub-custodian's system of internal accounting

                                       12
<PAGE>

controls as they relate to the Trust's assets.

         The Custodian will promptly  notify the Trust upon receiving  notices,
reports  or proxies  or  otherwise  becoming  aware of  corporate  developments
affecting assets held by foreign subcustodians (including,  but not limited to,
calls  for  redemption,   notices  of  maturities,   mergers,   consolidations,
reorganizations,   recapitualizations,   tender   offers,   rights   offerings,
exchanges,  subscriptions,  and other  offerings) and promptly  transmit to the
Trust copies of all communications and information received by the Custodian in
these regards.  The Custodian will do all things  reasonably within its control
in order to assure that  proxies  relating  to the  Trust's  assets held by the
foreign sub-custodian may be voted, to the extent that the Trust may legally do
so.

         13.      Branches of U.S. Banks

                  (a) Except as other wise set forth in this  amendment  to the
Agreement,  the  provisions  hereof  shall not apply  where the  custody of the
Trust's assets is maintained in a foreign branch of a banking  institution that
is a  "bank"  as  defined  by  Section  2(a)(5)  of the 1940  Act  meeting  the
qualification set forth in Section 26(a) of the said 1940 Act. The appointment

                                       13
<PAGE>

of any such  branch as a  sub-custodian  shall be  governed by Article 1 of the
Agreement.

                  (b) Cash held for the Trust in the  United  Kingdom  shall be
maintained in an interest  bearing  account  established for the Trust with the
Custodian's  London Branch,  which Account shall be subject to the direction of
the Custodian, State Street London Ltd. or both.

14.   Applicability of Custodian Agreement

                  Except as  specifically  superseded or modified  herein,  the
terms and  provisions of the Agreement  shall continue to apply with full force
and effect.

                                       14

         IN WITNESS WHEREOF,  each of the parties has caused this instrument to

         NOW THEREFORE, in consideration of the mutual covenants and agreements
hereinafter contained, the Custodian and the Subcustodian agree as follows:

I.       THE ACCOUNT

         A.  ESTABLISHMENT  OF THE  ACCOUNT.  Custodian  hereby  requests  that
Subcustodian  establish for each client of the Custodian an Account which shall
be composed of:

                  1.  A  Custody   Account  for  any  and  all  Securities  (as

any such property is held by Subcustodian in an Eligible  Depository,  shall be

government agency or regulatory  authority in the foreign  jurisdiction  having
authority  over such  depositories  or  agencies,  and which  operates  (a) the
central system for handling of designated securities or equivalent book entries
in ____________________________________________________________________________
or (b) a  transnational  system  for the  central  handling  of  securities  or
equivalent  book  entries  (herein  called  "Eligible  Depository"),   provided
however,  that,  while so maintained,  such Securities shall be subject only to
the directions of Subcustodian,  and that Subcustodian duties,  obligations and
responsibilities  with regard to such  Securities  shall be the same as if such
Securities were held by Subcustodian on its premises.

The property in the account shall not be subject to any right, charge, security
interest,  lien or  claim  of any  kind  (collectively  "Charges")  in favor of

any Eligible  Depository  except a claim for payment for such  property's  safe
custody  or  administration  in  accordance  with the terms of this  Agreement.
Subcustodian  will immediately  notify Custodian of any attempt by any party to

Subcustodian  shall  immediately  notify  Custodian,  in  writing  or by  other
authorized  means,  in  the  event  that  there  appears  to  be a  substantial
likelihood that  Subcustodian will cease to qualify under the Rule as currently
in effect or as hereafter amended, or

         (B) It is the  subject  of an  exemptive  order  issued by the  United
States  Securities  and Exchange  Commission  which order permits  Custodian to
employ Subcustodian notwithstanding the fact that Subcustodian fails to qualify
under  the  terms  of the  Rule,  and  Subcustodian  shall  immediately  notify
Custodian,  in writing or by other authorized means, if for any reason it is no
longer covered by such exemptive order.

Upon  receipt  of any  such  notification  required  under  (A) or (B) of  this

notice to Subcustodian.

testing or authentication  pursuant to terms and conditions which Custodian may
specify.

Unless otherwise  expressly  provided,  all Instructions shall continue in full
force and  effect  until  canceled  or  superseded.  Subcustodian  shall act in
accordance with Instructions and shall not be liable for any act or omission in
respect of any Instruction  except in the case of willful default,  negligence,
fraud, bad faith,  willful  misconduct,  or reckless disregard of duties on the
part of  Subcustodian.  Subcustodian  in executing all  Instructions  will take

settlement practice.

         B. ACCOUNT. The term "Account" means collectively the Custody Account,
and the Deposit Account.

         B.  EXAMINATION  OF BOOKS AND  RECORDS.  Subcustodian  agrees that its
books and records relating to the Account and Subcustodian's actions under this
Agreement  shall be open to the physical,  on-premises  inspection and audit at

of Property  under this  Agreement,  and in  fulfilling  any other  obligations
hereunder,  Subcustodian  shall  exercise  the same  standard  of care  that it
exercises  over its own assets,  PROVIDED that  Subcustodian  shall exercise at

prudent  professional  Subcustodian  for hire and shall  assume  the  burden of
proving that it has exercised such care in its  maintenance of Property held by
Subcustodian  in its Account.  The  maintenance  of the Property in an Eligible
Depository shall not affect  Subcustodian's  standard of care, and Subcustodian
will remain as fully  responsible  for any loss or damage to such securities as
if it had itself retained physical possession of them.  Subcustodian shall also
indemnify and hold harmless  Custodian and each of  Custodian's  customers from

to it to effect the quickest possible recovery.

         E.   COMPENSATION  OF   SUBCUSTODIAN.   Custodian  agrees  to  pay  to
Subcustodian  from time to time such  compensation  for its  services  and such
out-of-pocket or incidental expenses of Subcustodian pursuant to this Agreement

Custodian,  shall be followed  within 60 days by  Instructions  specifying  the
names of the persons to whom  Subcustodian  shall deliver the Securities in the
Account  and to whom the Cash in the account  shall be paid.  If within 60 days
