You can also find the most current price of your shares in the business section
of your newspaper in the mutual fund section under the heading "USAA Group" and
the symbol  "SciTech." If you prefer to obtain this information from an on-line
computer service, you can do so by using the ticker symbol "USSCX." 

You may see the Fund's total return quoted in advertisements  and reports.  All
mutual funds must use the same formula to calculate total return.  Total return
measures the price change in a share assuming the  reinvestment of all dividend
income and capital gain  distributions.  You may also see a  comparison  of the
Fund's  performance  to that of other  mutual  funds  with  similar  investment
objectives  and to stock or  relevant  indexes.  

For the period from the Fund's inception on August 1, 1997, through January 31,
1998, the Fund's cumulative total return was:

                                    (5.50%)

The  figure  on page 5 is  different  because  it is for a period  which  ended
December 31, 1997.
    
WILL THE VALUE OF YOUR
INVESTMENT FLUCTUATE?
   
Yes, it will.  The value of your  investment  will  fluctuate with the changing
market  value  of the  Fund's  portfolio.  The  Fund's  portfolio  consists  of
companies  whose value is highly  dependent  on  scientific  and  technological
developments.  Many of the products and services of these companies are subject
to short life cycles and competitive pressures.  Therefore, the market value of
the Fund's  portfolio  and the Fund's  price per share are likely to  fluctuate
significantly.  The table  shown on the next page  illustrates  how the  Fund's
cumulative  total  return  since  inception  compares to that of a  broad-based
securities  market  index.  Again,  remember  historical  performance  does not
necessarily indicate what will happen in the future.

A WORD ABOUT RISK
   
Portions of this Prospectus  describe the risks you will face as an investor in
the  Fund.  Keep in mind that  generally  investments  with a higher  potential
reward also have a higher risk of losing money.  The reverse is also  generally
true:  the lower the risk,  the lower the  potential  reward.  However,  as you
consider an  investment  in the Fund,  you should also take into  account  your
tolerance for the daily  fluctuations of the financial  markets and whether you
can afford to leave your money in this  investment  for long periods of time to
ride out down periods.  

[CAUTION LIGHT GRAPHIC]
Look for this symbol  throughout  the  Prospectus.  We use it to mark  detailed
information about the main risks that you will face as a Fund shareholder.

   A   Under normal  conditions,  we will invest at least 80% of the Fund's net
       assets  in  equity  securities  that we  expect  will  benefit  from the
       development  and  use  of  scientific  and  technological  advances  and
       improvements.  Most of these assets will be invested in U.S. securities;
       however, we may also invest the Fund's assets in foreign securities when
       they are in line with the Fund's investment objective.  For convenience,
       this Prospectus refers to common stocks,  preferred stocks,  convertible
       securities,  and  securities  which carry the right to buy common stocks
       collectively as "equity  securities." 

       As a temporary defensive measure, we may invest up to 100% of the Fund's
       assets in high-quality,  short-term debt instruments.  

       We generally  will  not  trade  the  Fund's  assets  in  securities  for
       short-term profits;  however, if circumstances  warrant, we may purchase
       and sell securities without regard to the length of time held. The

                                       5
<PAGE>

       Fund's portfolio  turnover rate will vary from year to year depending on
       market  conditions,  and is not expected to exceed 150%. A high turnover
       rate increases transaction costs and may increase taxable capital gains;
       therefore, we will carefully weigh the anticipated benefits of trading.

   Q   In what industries will the Fund's assets be invested?

   A   We will invest at least 80% of the Fund's net assets in industries  such
       as, but not limited to, biotechnology,  computer hardware,  software and
       services,  communication and  telecommunication  equipment and services,
       electronics,   health  care,  drugs,   medical  products  and  supplies,
       specialized  health care  services,  aerospace  and  defense,  and other
       industries  that we believe may benefit  indirectly  from  research  and
       development  in the science  and  technology  fields.  We may invest the
       Fund's remaining assets in any other industry.
    
   Q   What are the Fund's potential risks?

   A   Some of the potential risks of investing in this Fund include:  

       [CAUTION LIGHT GRAPHIC]
       INDUSTRY RISK. A mutual fund portfolio consisting of investments related
       to the fields of science and  technology  is likely to be more  volatile
       than a  portfolio  that is more  widely  diversified  in other  economic
       sectors.  Because of the competitiveness and rapid changes in the fields
       of science and technology, many of the companies in the Fund's portfolio
       are subject to  distinctive  risks.  The  products and services of these
       companies  may not be  economically  successful  or may  quickly  become
       outdated.  In  addition,  many  of  these  companies  must  comply  with
       significant  governmental regulations and may need governmental approval
       of their products and services.  
   
       [CAUTION LIGHT GRAPHIC]
       MARKET  RISK.  Because  this Fund  invests in equity  securities,  it is
       subject to stock market  risk.  Stock prices in general may decline over
       short or even extended periods,  regardless of the success or failure of
       an  individual  company's  operations.  The stock market tends 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.
    
       [CAUTION LIGHT GRAPHIC]   
       FOREIGN  INVESTING.  Investing in foreign securities poses unique risks:
       currency  exchange  rate  fluctuations;   foreign  market   illiquidity;
       increased price volatility; exchange control regulations;   

                                       6
<PAGE>

       foreign  ownership  limits;   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.
   
For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 17.
    
Investment Restrictions

The following restrictions may only be changed with shareholder approval: 

o   The Fund may not invest 25% or more of its total assets in one industry.

o   The Fund may not invest more than 5% of its total  assets in any one issuer
    or own  more  than  10% of the  outstanding  voting  securities  of any one
    issuer. This limitation does not apply to U.S. Government  securities,  and
    only applies to 75% of the Fund's total assets.

o   The Fund may borrow only for  temporary or emergency  purposes in an amount
    not exceeding 33 1/3% of its total assets.
   
You will find a complete listing of the precise investment  restrictions in the
Fund's Statement of Additional Information.

USING MUTUAL FUNDS
IN AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.
                                       8
<PAGE>

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.  
   
For example,  assume you wish to invest in a  widely-diversified,  common stock
portfolio.  You could combine an  investment  in the Science & Technology  Fund
with investments in other mutual funds that invest in stocks of large and small
companies  and  high-dividend  stocks.  This is just one way you could  combine
funds to fit your own risk and reward goals.
    
III. USAA's Family of Funds
   
We offer you another  alternative  with our asset  strategy  funds listed under
asset allocation on page 18. These unique mutual funds provide a professionally
managed  diversified  investment  portfolio  within  a  mutual  fund.  They are
designed  for the  individual  who  prefers to  delegate  the asset  allocation
process to an investment manager and are structured to achieve  diversification
across a number of investment categories.

Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales
representatives  stand  ready to assist you with your  choices  and to help you
craft a portfolio to meet your needs. 
    
HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required for each new account.  
                                          
                                       9
<PAGE>

TAX ID NUMBER  

Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

EFFECTIVE DATE 
   
When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading  session  (generally  4:00  p.m.  Eastern  Time) of the New York  Stock
Exchange  (NYSE) each day the NYSE is open. If we receive your request prior to
that time,  your purchase  price will be the NAV per share  determined for that
day. If we receive  your  request  after the NAV per share is  calculated,  the
purchase  will be effective on the next  business  day. If you plan to purchase
Fund shares with a foreign check,  we suggest you convert your foreign check to
U.S.  dollars prior to investment in the Fund to avoid a potential delay in the
effective date of your purchase of up to four to six weeks. Furthermore, a bank
charge may be assessed in the clearing process, which will be deducted from the
amount of the purchase.

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.  
    
In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic  investment  plan;  (2) any  account  registered  under  the  Uniform
Gifts/Transfers to Minors Act (UGMA/UTMA);  (3) all (non-IRA) money market fund
accounts;  (4) any account whose registered  owner has an aggregate  balance of
$50,000 or more  invested in USAA mutual  funds;  and (5) all IRA accounts (for
the first year the account is open).

Company Rights 

The Company reserves the right to:

o   reject  purchase  or  exchange  orders  when in the  best  interest  of the
    Company;

o   limit or discontinue the offering of shares of any portfolio of the Company
    without notice to the shareholders;
   
o   impose a  redemption  charge of up to 1% of the net  asset  value of shares
    redeemed if circumstances indicate a charge is necessary for the protection
    of remaining  investors  (for  example,  if excessive  market-timing  share
    activity unfairly burdens  long-term  investors);  however,  this 1% charge
    will not be imposed upon  shareholders  unless  authorized  by the Board of
    Directors and the required notice has been given to shareholders;

o   require a  signature  guarantee  for  transactions  or  changes  in account
    information in those  instances  where the  appropriateness  of a signature
    authorization  is in  question.  The  Statement of  Additional  Information
    contains information on acceptable guarantors;
    
o   redeem an account with less than 10 shares, with certain limitations.

EXCHANGES

Exchange Privilege
   
The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously process exchange redemptions and purchases at the share 

                                      13
<PAGE>

prices next determined after the exchange order is received. For federal income
tax purposes,  an exchange  between Funds is a taxable event;  and as such, you
may realize a capital gain or loss.

The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 12.
    
Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds). 
    
SHAREHOLDER INFORMATION

Share Price Calculation
   
The price at which you  purchase  and  redeem  Fund  shares is equal to the net
asset value (NAV) per share determined on the effective date of the purchase or
redemption.  You may 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.
The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 45 days of the July 31  fiscal  year end,
which would be  somewhere  around the middle of  September.  The Fund will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the Fund shares computed on the ex-dividend date. Any income
dividends  or capital gain  distributions  paid by the Fund will reduce the NAV
per share by the amount of the dividend or  distribution.  These  dividends and
distributions are subject to taxes.

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become void six months from the date on the check. The amount 

                                      14
<PAGE>

of the voided  check will be invested in your account at the  then-current  NAV
per share.

Federal Taxes
   
This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be adopted
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state and locality.  

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital losses.  
    
SHAREHOLDER - Dividends from taxable net investment  income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares. A portion of these
dividends may qualify for the 70%  dividends  received  deduction  available to
corporations.  

Regardless  of the length of time you have held the Fund shares,  distributions
of net long-term  capital gains are taxable as long-term  capital gains whether
received in cash or reinvested in additional shares.  
   
Redemptions  and  exchanges  are subject to income tax based on the  difference
between  the  cost of  shares  when  purchased  and  the  price  received  upon
redemption or exchange. 
    
WITHHOLDING  - Federal law  requires the Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who: 
   
o   fails to furnish the Fund with a correct tax identification number,
o   underreports dividend or interest income, or
o   fails to certify that he or she is not subject to withholding. 

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - The Fund will report  information  to you concerning the tax status
of dividends and distributions for federal income tax purposes annually.

DESCRIPTION OF SHARES 
   
The Fund is a series of USAA Mutual Fund,  Inc.  (Company) and is  diversified.
The Company is an open-end management investment company incorporated under the
laws of the State of  Maryland.  The Company is  authorized  to issue shares of
common  stock of separate  series,  each of which is commonly  referred to as a
mutual fund. There are ten mutual funds in the Company, including this Fund. As
of January 31, 1998, USAA and its affiliates owned  approximately  27.5% of the
Fund's shares.

The Company does not hold annual or regular  meetings of shareholders and holds
special  meetings only as required by the  Investment  Company Act of 1940. The
Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate vote of that specific fund's shareholders.  Shareholders  collectively
holding at least 10% of the  outstanding  shares of the  Company  may request a
shareholder meeting at any time for the purpose of voting to remove one or more
of  the  Directors.   The  Company  will  assist  in   communicating  to  other
shareholders about the meeting.

                                   APPENDIX A

The following are  descriptions  of certain types of securities in which we may
invest the Fund's assets:

CONVERTIBLE SECURITIES
   
We may invest in convertible  securities which are bonds, preferred stocks, and
other  securities that pay interest or dividends and offer the buyer the option
of  converting  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.
    
MONEY MARKET INSTRUMENTS
   
We may hold a  certain  portion  of the  Fund's  assets in  high-quality,  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,   bank  deposits,   and  other  financial   institution
obligations. These securities may carry fixed or variable interest rates.
    
ILLIQUID SECURITIES

We may not invest more than 15% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately the value at which the Fund has valued the securities.

FORWARD CURRENCY CONTRACTS
   
We may hold securities  denominated in foreign  currencies.  The value of these
securities  will be affected by changes in the exchange rate between the dollar
and the foreign  currencies.  In managing currency exposure,  we may enter into
forward  currency  contracts.  A forward  currency  contract is 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.

The  Fund is a  no-load  mutual  fund  offered  by USAA  Investment  Management

program to stimulate interest in long-term investing by young people.

The  USAA  First  Start  Growth  Fund  is part of  USAA  First  Start,  a money
management plan for young people.

SHARES OF THIS FUND ARE NOT DEPOSITS OR OTHER OBLIGATIONS OF, OR GUARANTEED BY,
THE USAA  FEDERAL  SAVINGS  BANK,  ARE NOT  INSURED  BY THE  FDIC OR ANY  OTHER
GOVERNMENT AGENCY, ARE SUBJECT TO INVESTMENT RISKS, AND MAY LOSE VALUE.

AS WITH  OTHER  MUTUAL  FUNDS,  THESE  SECURITIES  HAVE  NOT BEEN  APPROVED  OR
DISAPPROVED  BY THE SECURITIES  AND EXCHANGE  COMMISSION  (SEC) NOR HAS THE SEC
PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO

You can also find the most current price of your shares in the business section
of your newspaper in the mutual fund section under the heading "USAA Group" and
the symbol  "FStrtGr." If you prefer to obtain this information from an on-line
computer service, you can do so by using the ticker symbol "USFGX." 

You may see the Fund's total return quoted in advertisements  and reports.  All
mutual funds must use the same formula to calculate total return.  Total return
measures the price change in a share assuming the  reinvestment of all dividend
income and capital gain  distributions.  You may also see a  comparison  of the
Fund's  performance  to that of other  mutual  funds  with  similar  investment
objectives  and to stock or  relevant  indexes.  

For the period from the Fund's inception on August 1, 1997, through January 31,
1998, the Fund's cumulative total return was: 

                                     2.50%

The  figure  on page 5 is  different  because  it is for a period  which  ended
December 31, 1997.
    
WILL THE VALUE OF YOUR
INVESTMENT FLUCTUATE?
   
Yes, it will.  The value of your  investment  will  fluctuate with the changing
market value of the Fund's portfolio. You may have a gain or loss when you sell
your  shares.  The table  shown on the next  page  illustrates  how the  Fund's
cumulative  total  return  since  inception  compares to that of a  broad-based
securities  market  index.  Again,  remember  historical  performance  does not
necessarily indicate what will happen in the future.

A WORD ABOUT RISK
   
Portions of this Prospectus  describe the risks you will face as an investor in
the  Fund.  Keep in mind that  generally  investments  with a higher  potential
reward also have a higher risk of losing money.  The reverse is also  generally
true:  the lower the risk,  the lower the  potential  reward.  However,  as you
consider an  investment  in the Fund,  you should also take into  account  your

FUND INVESTMENTS

Investment Policies and Risks

    Q  What is the Fund's investment policy?

    A  We will invest the Fund's assets in equity  securities of companies that
       provide  goods or services that we believe are familiar to young people.
       For  convenience,  this  Prospectus  refers to common stocks,  preferred
       stocks,  convertible securities, and securities which carry the right to
       buy  common  stocks  collectively  as "equity  securities."  Most of the
       Fund's assets will be invested in U.S. securities;  however, we may also
       invest the Fund's  assets in  foreign  securities  when they are in line
       with the Fund's investment objective.  

       We designed  the Fund as part  of a  program to  stimulate  interest  in
       long-term  investing by young people.  Shareholders of the Fund may give
       us their  suggestions  about the types of companies that they would like
       us to consider for investment by the Fund. We

                                       5
<PAGE>

       invite  shareholders  to tell us the  investment  topics or the names of
       stocks  that they would like us to feature in the Fund's  communications
       to shareholders.  

       As a temporary defensive measure, we may invest up to 100% of the Fund's
       assets in high-quality, short-term debt instruments.
   
    Q  In what industries will the Fund's assets be invested?
    
    A  We will invest the Fund's assets in many different industries.  The Fund
       is not a  "sector"  fund that  focuses  its  investments  in a  specific
       industry  or sector of the  economy.  We believe  that goods or services
       that are  likely to be  familiar  to young  investors  are  provided  by
       companies engaged in many different types of industries.  Such companies
       may include  computer  hardware  and  software  manufacturers,  Internet
       service   providers,   and   companies  in  the   apparel,   automobile,
       communications,  entertainment, financial services, health services, and
       travel  industries,  among others.  We believe that the  flexibility  to
       select  equity  securities  of  companies  across  a broad  universe  of
       industries  maximizes our opportunity to find attractive  investments as
       we pursue the Fund's objective of long-term capital appreciation.
   
    Q  Are the Fund's  assets  prohibited  from being  invested in any specific
       industries?
    
    A  Yes. We will not invest the Fund's  assets in  companies  whose  primary
       line of  business is the  production  of tobacco  products or  alcoholic
       beverages.  Investments in firms primarily  focused on gaming activities
       are also prohibited.

    Q  What special services are provided to shareholders in this Fund?

    A  In addition to providing an investment opportunity for long-term capital
       appreciation, shareholders will receive educational information targeted
       to young people about the basic concepts of saving and investing.

    Q  What are the Fund's potential risks?

    A  Two potential risks of investing in this Fund include:  
   
    [CAUTION LIGHT GRAPHIC]  
    MARKET RISK. Because this Fund invests in equity securities,  it is subject
    to stock market risk. Stock prices in general may decline 

                                       6
<PAGE>

    over short or even extended  periods,  regardless of the success or failure
    of an  individual  company's  operations.  The stock market tends 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.
    
    [CAUTION LIGHT GRAPHIC]
    FOREIGN  INVESTING.  Investing in foreign  securities  poses unique  risks:
    currency exchange rate fluctuations;  foreign market illiquidity; increased
    price volatility;  exchange control regulations;  foreign ownership limits;
    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.
   
For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 17.
    
Investment Restrictions

The following restrictions may only be changed with shareholder approval:

o   The Fund may not invest 25% or more of its total assets in one industry.

o   The Fund may not invest more than 5% of its total  assets in any one issuer
    or own  more  than  10% of the  outstanding  voting  securities  of any one
    issuer. This limitation does not apply to U.S. Government  securities,  and
    only applies to 75% of the Fund's total assets.

o   The Fund may borrow only for  temporary or emergency  purposes in an amount
    not exceeding 33 1/3% of its total assets.
   
You will find a complete listing of the precise investment  restrictions in the
Fund's Statement of Additional Information.

USING MUTUAL FUNDS IN
AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds 

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.  

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.  
   
For example,  assume you wish to invest in a  widely-diversified,  common stock
portfolio.  You could combine an investment in the First Start Growth Fund with
investments  in other  mutual  funds  that  invest in stocks of large and small
companies  and  high-dividend  stocks.  This is just one way you could  combine
funds to fit your own risk and reward goals.
    
III. USAA's Family of Funds
   
We offer you another  alternative  with our asset  strategy  funds listed under
asset allocation on page 18. These unique mutual funds provide a professionally
managed  diversified  investment  portfolio  within  a  mutual  fund.  They are
designed  for the  individual  who  prefers to  delegate  the asset  allocation
process to an investment manager and are structured to achieve  diversification
across a number of investment categories. 

                                       9
<PAGE>

Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales
representatives  stand  ready to assist you with your  choices  and to help you
craft a portfolio to meet your needs. 
    
HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required for each new account.  
    
TAX ID NUMBER  

Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements. 

EFFECTIVE DATE 
   
When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading  session  (generally  4:00  p.m.  Eastern  Time) of the New York  Stock
Exchange  (NYSE) each day the NYSE is open. If we receive your request prior to
that time,  your purchase  price will be the NAV per share  determined for that
day. If we receive  your  request  after the NAV per share is  calculated,  the
purchase  will be effective on the next  business  day. If you plan to purchase
Fund shares with a foreign check,  we suggest you convert your foreign check to
U.S.  dollars prior to investment in the Fund to avoid a potential delay in the
effective date of your purchase of up to four to six weeks. Furthermore, a bank
charge may be assessed in the clearing process, which will be deducted from the
amount of the purchase. 
    
MINIMUM INVESTMENTS  
   
INITIAL PURCHASE     
[MONEY GRAPHIC]        

o    $3,000 [$250 Uniform  Gifts/Transfers  to Minors Act (UGMA/UTMA)  accounts
     and $250 for IRAs] or no initial  investment  if you elect to have monthly
     electronic  investments  of at least $20 each. We may  periodically  offer
     programs   that  reduce  the  minimum   amounts  for  monthly   electronic
     investments.  Employees of USAA and its  affiliated  companies may open an
     account through payroll deduction for as little as $25 per pay period with
     no initial investment.

Redemption of Shares
   
You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  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. 

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.  
    
In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services
   
[BOOK GRAPHIC]
Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual  fund  account and to help you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.
    
Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic  investment  plan;  (2) any  account  registered  under  the  Uniform
Gifts/Transfers to Minors Act (UGMA/UTMA);  (3) all (non-IRA) money market fund
accounts;  (4) any account whose registered  owner has an aggregate  balance of
$50,000 or more  invested in USAA mutual  funds;  and (5) all IRA accounts (for
the first year the account is open).

Company Rights 

The Company reserves the right to:
 
o   reject  purchase  or  exchange  orders  when in the  best  interest  of the
    Company;

o   limit or discontinue the offering of shares of any portfolio of the Company
    without notice to the shareholders;
   
o   impose a  redemption  charge of up to 1% of the net  asset  value of shares
    redeemed if circumstances indicate a charge is necessary for the protection
    of remaining  investors  (for  example,  if excessive  market-timing  share
    activity unfairly burdens  long-term  investors);  however,  this 1% charge
    will not be imposed upon  shareholders  unless  authorized  by the Board of
    Directors and the required notice has been given to shareholders; 

                                      13
<PAGE>

o   require a  signature  guarantee  for  transactions  or  changes  in account
    information in those  instances  where the  appropriateness  of a signature
    authorization  is in  question.  The  Statement of  Additional  Information
    contains information on acceptable guarantors;
    
o   redeem an account with less than 10 shares, with certain limitations.

EXCHANGES

Exchange Privilege
   
The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously  process exchange  redemptions and purchases at the share prices
next  determined  after the exchange order is received.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital gain or loss.

The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 12.
    
Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds). 
    
SHAREHOLDER INFORMATION


Share Price Calculation
   
The price at which you  purchase  and  redeem  Fund  shares is equal to the net
asset value (NAV) per share determined on the effective date of the purchase or
redemption.  You may 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.
The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 45 days of the July 31  fiscal  year end,
which would be  somewhere  around the middle of  September.  The Fund will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the Fund shares computed on the ex-dividend date. Any income
dividends  or capital gain  distributions  paid by the Fund will reduce the NAV
per share by the amount of the dividend or  distribution.  These  dividends and
distributions are subject to taxes. 

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

Federal Taxes
   
This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be adopted
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state and locality.

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital losses.
    
SHAREHOLDER - Dividends from taxable net investment income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares. A portion of these
dividends may qualify for the 70%  dividends  received  deduction  available to
corporations.  

Regardless  of the length of time you have held the Fund shares,  distributions
of net long-term  capital gains are taxable as long-term  capital gains whether
received in cash or reinvested in additional shares.  

                                      15
<PAGE>
   
Redemptions  and  exchanges  are subject to income tax based on the  difference
between  the  cost of  shares  when  purchased  and  the  price  received  upon
redemption or exchange. 
    
WITHHOLDING - Federal law requires the Fund to withhold
and remit to the U.S.  Treasury a portion of the income  dividends  and capital
gain  distributions  and  proceeds  of  redemptions  paid to any  non-corporate
shareholder who: 
   
o  fails to furnish the Fund with a correct tax identification number, 
o  underreports  dividend or interest income, or 
o  fails to certify that he or she is not subject to withholding.

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding. 

REPORTING - The Fund will report  information  to you concerning the tax status
of dividends and distributions for federal income tax purposes annually.

Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate vote of that specific fund's shareholders.  Shareholders  collectively
holding at least 10% of the  outstanding  shares of the  Company  may request a
shareholder meeting at any time for the purpose of voting to remove one or more
of  the  Directors.   The  Company  will  assist  in   communicating  to  other
shareholders about the meeting.

                                   APPENDIX A

THE FOLLOWING ARE  DESCRIPTIONS  OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST THE FUND'S ASSETS:  

CONVERTIBLE SECURITIES
   
We may invest in convertible securities, which are bonds, preferred stocks, and
other  securities that pay interest or dividends and offer the buyer the option
of  converting  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.
    
MONEY MARKET INSTRUMENTS
   
We may hold a  certain  portion  of the  Fund's  assets in  high-quality,  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,   bank  deposits,   and  other  financial   institution
obligations. These securities may carry fixed or variable interest rates.
    
ILLIQUID SECURITIES

We may not invest more than 15% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately the value at which the Fund has valued the securities.

FORWARD CURRENCY CONTRACTS 
   
We may hold securities  denominated in foreign  currencies.  The value of these
securities  will be affected by changes in the exchange rate between the dollar
and the foreign  currencies.  In managing currency exposure,  we may enter into
forward  currency  contracts.  A forward  currency  contract is 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 a foreign currency and desires to
"lock in" the U.S. dollar price of that security.

                            VALUATION OF SECURITIES

Shares of each Fund are offered on a continuing best efforts basis through USAA
Investment  Management  Company (IMCO or the Manager).  The offering  price for
shares of each Fund is equal to the  current  net asset  value (NAV) per share.
The NAV per share of each  Fund is  calculated  by adding  the value of all its
portfolio securities and other assets, deducting its liabilities,  and dividing
by the number of shares outstanding.
    
     Each Fund's NAV per share is calculated  each day,  Monday through Friday,
except days on which the New York Stock Exchange (NYSE) is closed.  The NYSE is
currently scheduled to be closed on New Year's Day, Martin Luther King Jr. Day,
Presidents'  Day,  Good Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving,  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 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.  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 depending upon local custom
     or regulation.

(2)  Over-the-counter  securities are priced at the last sales price or, if not
     available,  at the average of the bid and asked prices at the time trading
     closes on the NYSE.

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

(4)  Other debt securities may be valued each business day by a pricing service
     (the  Service)  approved by the Board of  Directors.  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,  indications  as to values  from  dealers  in
     securities,  and general market conditions. 

(5)  Securities  which cannot be valued by the methods set forth above, and all
     other  assets,  are  valued  in good  faith at fair  value  using  methods
     determined  by the Manager under the general  supervision  of the Board of
     Directors. 
     
     Securities  trading in foreign  markets  may not take place on all days on
which the NYSE is open. Further, trading takes place in various foreign markets
on days on which the NYSE is not  open.  The  calculation  of each  Fund's  NAV
therefore may not take place  contemporaneously  with the  determination of the
prices  of  securities  held by each  Fund.  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  reflected  in the  Fund's  NAV,  unless  the  Manager
determines  that the particular  event would  materially  affect NAV. In such a
case, the Fund's Manager, under the supervision of the Board of Directors, will
use all  relevant  available  information  to  determine  a fair  value for the
affected portfolio securities.

                     CONDITIONS OF PURCHASE AND REDEMPTION
   
NONPAYMENT

If any order to purchase shares is canceled due to nonpayment or if the Company
does not receive good funds either by check or electronic funds transfer,  USAA
Shareholder  Account Services (Transfer Agent) will treat the cancellation as a
redemption of shares  purchased,  and you will be responsible for any resulting
loss  incurred  by the  Fund  or the  Manager.  If you are a  shareholder,  the
Transfer Agent can redeem shares from any of your  account(s) as  reimbursement
for all losses.  In addition,  you may be prohibited or restricted  from making
future  purchases in any of the USAA Family of Funds.  A $15 fee is charged for
all returned items, including checks and electronic funds transfers.

TRANSFER OF SHARES 

You may transfer Fund shares to another person by sending written  instructions
to the Transfer  Agent.  The account must be clearly  identified,  and you must
include  the  number  of  shares  to be  transferred,  the  signatures  of  all
registered owners, and all stock certificates, if any, which are the subject of
transfer.  You also need to send written  instructions signed by all registered
owners and supporting documents to change an account registration due to events
such as divorce,  marriage, or death. If a new account needs to be established,
you must complete and return an application to the Transfer Agent.
    
                                       2
<PAGE>
             ADDITIONAL INFORMATION REGARDING REDEMPTION OF SHARES
   
The value of your investment at the time of redemption may be more or less than
the cost at  purchase,  depending on the value of the  securities  held in each
Fund's  portfolio.  Requests  for  redemption  which are subject to any special
conditions,  or which specify an effective date other than as provided  herein,
cannot be accepted. A gain or loss for tax purposes may be realized on the sale
of shares,  depending upon the price when redeemed.  

     The Board of  Directors  may cause the  redemption  of an  account  with a
balance  of less  than 10 shares  of each  Fund  provided  (1) the value of the
account has been  reduced,  for reasons  other than  market  action,  below the
minimum initial  investment in the Fund at the time of the establishment of the
account,  (2) the account has remained  below the minimum level for six months,
and (3) 60 days' prior written notice of the proposed  redemption has been sent
to you.  Shares will be redeemed at the NAV on the date fixed for redemption by
the Board of Directors.  Prompt payment will be made by mail to your last known
address.  

     The  Company  reserves  the right to suspend  the right of  redemption  or
postpone  the date of  payment  (1) for any  periods  during  which the NYSE is
closed,  (2) when  trading in the  markets  the  Company  normally  utilizes is
restricted, or an emergency exists as determined by the Securities and Exchange
Commission (SEC) so that disposal of the Company's investments or determination
of its net asset  value is not  reasonably  practicable,  or (3) for such other
periods  as the  SEC by  order  may  permit  for  protection  of the  Company's
shareholders.  
    
     For the mutual  protection of the investor and the Funds,  the Company may
require a signature  guarantee.  If  required,  EACH  signature  on the account
registration must be guaranteed.  Signature guarantees are acceptable from FDIC
member  banks,  brokers,  dealers,   municipal  securities  dealers,  municipal
securities  brokers,   government  securities  dealers,  government  securities
brokers,  credit unions,  national securities exchanges,  registered securities
associations, clearing agencies and savings associations. A signature guarantee
for active  duty  military  personnel  stationed  abroad may be  provided by an
officer of the United States Embassy or Consulate, a staff officer of the Judge
Advocate General, or an individual's commanding officer.

                                INVESTMENT PLANS
   
The Company makes available the following  investment  plans to shareholders of
each Fund.  At the time you sign up for any of the following  investment  plans
that utilize the electronic funds transfer service,  you will choose the day of
the month (the  effective  date) on which you would like to regularly  purchase
shares.  When this day falls on a weekend or holiday,  the electronic  transfer
will take place on the last  business day before the  effective  date.  You may
terminate your participation in a plan at any time. Please call the Manager for
details  and  necessary  forms or  applications.  
    
AUTOMATIC  PURCHASE OF SHARES
   
INVESTART(R)  - A no  initial  investment  purchase  plan.  With  this plan the
regular  minimum  initial  investment  amount  is  waived  if you make  monthly
additions of at least $50 through  electronic funds transfer from a checking or
savings account for the Science & Technology Fund. 
    
INVESTRONIC(R) - The regular purchase of additional  shares through  electronic
funds transfer from a checking or savings account.  You may invest as little as
$50 per month.
   
DIRECT PURCHASE  SERVICE - The periodic  purchase of shares through  electronic
funds  transfer from an employer  (including  government  allotments and social
security), an income-producing  investment,  or an account with a participating
financial institution.
    
AUTOMATIC  PURCHASE  PLAN - The  periodic  transfer  of funds from a USAA money
market fund to purchase  shares in another  non-money  market USAA mutual fund.
There is a minimum investment  required for this program of $5,000 in the money
market fund, with a monthly  transaction minimum of $50.

BUY/SELL  SERVICE - The  intermittent  purchase or redemption of shares through
electronic   funds  transfer  to  or  from  a  checking  or  savings   account.

   
     Participation in these automatic  purchase plans will permit you to engage
in dollar-cost averaging. For additional information concerning the benefits of
dollar-cost averaging, see APPENDIX C.
    
SYSTEMATIC WITHDRAWAL PLANS 
   
If a shareholder in a single  investment  account  (accounts in different Funds
cannot be  aggregated  for this  purpose) owns shares having a NAV of $5,000 or
more, the  shareholder may request that enough shares to produce a fixed amount
of money be liquidated  from the account  monthly or  quarterly.  The amount of
each  withdrawal  must be at least $50.  Using the  electronic  funds  transfer
service,  you may choose to have withdrawals  electronically  deposited at your
bank or other financial  institution.  You may also elect to have checks mailed
to a designated  address.  
    
                                       3
<PAGE>
   
     Such a plan may be  initiated by  depositing  shares worth at least $5,000
with  the  Transfer  Agent  and by  completing  a  Systematic  Withdrawal  Plan
application,  which  may be  requested  from  the  Manager.  You may  terminate
participation  in  the  plan  at any  time.  There  is no  charge  to  you  for
withdrawals under the Systematic Withdrawal Plan. The Company will not bear any
expenses  in  administering  the plan  beyond the  regular  transfer  agent and
custodian  costs of issuing and  redeeming  shares.  The Manager  will bear any
additional expenses of administering the plan.

     Withdrawals  will be made by redeeming full and  fractional  shares on the
date you select at the time the plan is established.  Withdrawal  payments made
under this plan may exceed  dividends  and  distributions  and, to this extent,
will  involve the use of  principal  and could  reduce the dollar value of your
investment  and  eventually  exhaust the  account.  Reinvesting  dividends  and
distributions  helps  replenish  the  account.  Because  share  values  and net
investment income can fluctuate, you should not expect withdrawals to be offset
by rising income or share value gains.

     Each  redemption  of shares  may  result in a gain or loss,  which must be
reported  on your  income tax  return.  Therefore,  you should keep an accurate
record of any gain or loss on each withdrawal.
    
TAX-DEFERRED  RETIREMENT PLANS
   
    Federal taxes on current  income may be deferred if you qualify for certain
types of retirement programs. For your convenience, the Manager makes available
various forms of IRA and 403(b)(7) accounts.  The minimum initial investment in
each of these plans is $250. No minimum  initial  investment is required with a
monthly electronic  investment in the Science & Technology Fund and First Start
Growth  Fund of at least  $50 and $20,  respectively.  You may make  additional
investments of $50 or more in the Science & Technology  Fund and $20 or more in
the First Start Growth Fund at any time. You may make investments in one or any
combination of the portfolios  described in the Prospectus of each Fund of USAA
Mutual Fund,  Inc. and USAA  Investment  Trust (not available in the Growth and
Tax Strategy Fund).

     Retirement plan applications for the IRA and 403(b)(7)  programs should be
sent directly to USAA Shareholder Account Services,  9800 Fredericksburg  Road,
San Antonio,  TX 78288. USAA Federal Savings Bank serves as Custodian for these
tax-deferred retirement plans under the programs made available by the Manager.
Applications  for  these  retirement  plans  received  by the  Manager  will be
forwarded to the Custodian for acceptance.

An  administrative  fee of $20 is  deducted  from the  money  sent to you after
closing an account.  Exceptions to the fee are:  partial  distributions,  total
transfer within USAA, and distributions due to disability or death. This charge
is  subject  to change as  provided  in the  various  agreements.  There may be
additional charges, as mutually agreed upon between you and the Custodian,  for
further services requested of the Custodian.

Each employer or individual  establishing  a  tax-deferred  retirement  plan is
advised to consult with a tax adviser  before  establishing  the plan.  You may
obtain detailed information about the plans from the Manager.
    
                              INVESTMENT POLICIES

The section captioned FUND INVESTMENTS in each Fund's Prospectus  describes the
fundamental investment objective and the investment policies applicable to each
Fund and the following is provided as additional information.

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

Each Fund may invest in  commercial  paper  issued in reliance on the  "private
placement"  exemption  from  registration  afforded  by  Section  4(2)  of  the
Securities Act of 1933 (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.

     Each Fund 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.

LIQUIDITY  DETERMINATIONS 

The Board of Directors  has  established  guidelines  pursuant to which 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  (Restricted  Put Bonds) may be  determined  to be liquid for
purposes of complying  with the Funds'  investment  restrictions  applicable to
investments in illiquid securities. In

                                       4
<PAGE>

determining  the  liquidity  of  Section  4(2)  Commercial  Paper and Rule 144A
Securities,  the Manager will  consider the  following  factors,  among others,
established  by the Board of Directors:  (1) the frequency of trades and quotes
for the  security,  (2) the number of dealers  willing to  purchase or sell the
security and the number of other potential purchasers,  (3) dealer undertakings
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.  In
determining  the liquidity of Restricted  Put Bonds,  the Manager 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
Restricted Put Bond. In evaluating the credit quality of the Put Provider,  the
Manager will  consider all factors that it deems  indicative of the capacity of
the Put Provider to meet its  obligations  under the  Restricted Put Bond based
upon a review of the Put Provider's  outstanding debt and financial  statements
and general economic conditions.

    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 Directors.

FORWARD CURRENCY CONTRACTS  

Each Fund may enter into forward currency contracts in order to protect against
uncertainty in the level of future foreign exchange rates.
   
     A forward contract is an agreement to purchase or sell a specific currency
at a specified  future  date or over 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. 
    
     Each  Fund  may  enter  into   forward   currency   contracts   under  two
circumstances.  First, when the Fund enters into a contract for the purchase or
sale of a security  denominated in a foreign  currency,  it may desire to "lock
in" the U.S.  dollar price of the  security.  By entering into such a contract,
the Fund will be able to protect  itself against a possible loss resulting from
an adverse change in the  relationship  between the U.S. dollar and the foreign
currency  from the date the  security is purchased or sold to the date on which
payment is made or received.  Second, when management of the Fund believes that
the currency of a specific country may deteriorate relative to the U.S. dollar,
it may enter into a forward  contract to sell that  currency.  The Fund may not
hedge with  respect to a  particular  currency  for an amount  greater than the
aggregate  market value  (determined  at the time of making any sale of forward
currency) of the securities held in its portfolio  denominated or quoted in, or
bearing a substantial correlation to, such currency.  

     The use of forward contracts  involves certain risks. The precise matching
of contract amounts and the value of securities  involved generally will not be
possible  since the future value of such  securities  in  currencies  more than
likely will change  between the date the  contract is entered into and the date
it matures. The projection of short-term currency market movements is extremely
difficult  and  successful  execution  of  a  short-term  hedging  strategy  is
uncertain.  Under  normal  circumstances,  consideration  of the  prospect  for
currency  parities  will  be  incorporated  into  the  longer  term  investment
strategies.  The  Manager  believes  it is  important,  however,  to  have  the
flexibility  to enter into such  contracts when it determines it is in the best
interest of a Fund to do so. It is impossible to forecast what the market value
of portfolio  securities will be at the expiration of a contract.  Accordingly,
it may be necessary for the Fund to purchase  additional currency (and bear the
expense of such  purchase) if the market value of the security is less than the
amount of currency a Fund is obligated to deliver, and if a decision is made to
sell the  security and make  delivery of the  currency.  Conversely,  it may be
necessary  to sell some of the  foreign  currency  received  on the sale of the
portfolio  security if its market value exceeds the amount of currency the Fund
is obligated to deliver.  

     Each Fund is not required to enter into such  transactions and will not do
so unless deemed appropriate by the Manager.  
   
     Although  each 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 you should be aware of
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 a foreign  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.  
    
CONVERTIBLE  SECURITIES  
   
Convertible  securities are bonds,  preferred stocks, and other securities that
pay  interest or  dividends  and offer the buyer the option of  converting  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 
                                       5
<PAGE>

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. 

     The  convertible  securities  in which each Fund may invest could be rated
below  investment  grade as  determined  by  Moody's  Investors  Service,  Inc.
(Moody's) or Standard & Poor's  Ratings  Group (S&P),  or unrated but judged by
the Manager to be of comparable  quality  (commonly  called junk bonds).  For a
more complete  description of debt ratings, see APPENDIX A. Such securities are
deemed to be speculative  and involve greater risk of default due to changes in
interest rates, economic conditions,  and the issuer's  creditworthiness.  As a
result,  their  market  prices  tend  to  fluctuate  more  than  higher-quality
securities.  During periods of general  economic  downturns or rising  interest
rates, issuers of such securities may experience  financial  difficulties which
could affect their ability to make timely interest and principal payments. Each
Fund's  ability to timely and  accurately  value and  dispose of  lower-quality
securities  may also be affected by the absence or periodic  discontinuance  of
liquid trading markets.
    
                            INVESTMENT RESTRICTIONS
   
The following investment restrictions have been adopted by the Company for each
Fund. These restrictions 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.
    
Each Fund may not: 

(1) With respect to 75% of its total  assets,  purchase the  securities  of any
    issuer (except U.S. Government  Securities,  as such term is defined in the
    1940 Act) if, as a  result,  it would own more than 10% of the  outstanding
    voting securities of such issuer or it would have more than 5% of the value
    of its total assets invested in the securities of such issuer.

(2) Borrow money,  except 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).

(3) Invest  25% or more of the value of its total  assets in any one  industry;
    provided, this limitation does not apply to securities issued or guaranteed
    by the U.S. Government and its agencies or instrumentalities.

(4) Issue senior securities, except as permitted under the 1940 Act.

(5) 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.

(6) 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.

(7) Purchase or sell commodities, except that each Fund may invest in financial
    futures contracts, options thereon, and similar instruments.

(8) Purchase or sell real estate  unless  acquired as a result of  ownership of
    securities  or other  instruments,  except  that  each  Fund may  invest in
    securities  or other  instruments  backed by real estate or  securities  of
    companies  that  deal in real  estate  or are  engaged  in the real  estate
    business.
   
    With respect to each Fund's  concentration policy as described above and in
its Prospectus,  the Manager uses industry  classifications based on categories
established  by  Standard  & Poor's  Corporation  (Standard  & Poor's)  for the
Standard & Poor's 500 Composite Index, with certain modifications.  Because the
Manager has determined that certain categories within, or in addition to, those
set  forth  by  Standard  &  Poor's  have  unique  investment  characteristics,
additional industries are included as industry classifications.
    
ADDITIONAL RESTRICTION 
   
The following  restriction is not considered to be a fundamental  policy of the
Funds.  The Board of Directors may change this additional  restriction  without
notice to or approval by the shareholders. 
    
Each Fund may not: 

(1) Purchase any security  while  borrowings  representing  more than 5% of the
Fund's total assets are outstanding.

                             PORTFOLIO TRANSACTIONS

The Manager,  pursuant to the Advisory  Agreement dated September 21, 1990, and
subject to the general control of the Company's Board of Directors,  places all
orders for the purchase  and sale of Fund  securities.  In executing  portfolio
transactions and selecting  brokers and dealers,  it is the Company's policy to
seek the best overall terms available.  The Manager shall 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 or 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 Manager, better prices and execution are available elsewhere.
   
     The Funds will have no  obligation to deal with any  particular  broker or
group  of  brokers  in the  execution  of  portfolio  transactions.  The  Funds
contemplate  that,  consistent with obtaining the best overall terms available,
brokerage  transactions  may be effected  through USAA  Brokerage  Services,  a
discount brokerage service of the Manager. The Company's Board of Directors has
adopted procedures in conformity with Rule 17e-1 under the 1940 Act designed to
ensure that all  brokerage  commissions  paid to USAA  Brokerage  Services  are
reasonable  and fair.  The  Company's  Board of Directors  has  authorized  the
Manager,  as a member  of the  Chicago  Stock  Exchange,  to  effect  portfolio
transactions  for the  Funds 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,  preference may be given to those
broker-dealers who provide research or other services to the Manager as long as
there is no sacrifice  in obtaining  the best  overall  terms  available.  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 Manager  determines  in good faith that such  commission  is  reasonable in
terms of either that particular transaction or of the overall responsibility of
the Manager to the Funds and its other  clients.  The receipt of research  from
broker-dealers that execute transactions on behalf of the Company may be useful
to the Manager in rendering  investment  management  services to other  clients
(including affiliates of the Manager),  and conversely,  such research provided
by  broker-dealers  who have  executed  transaction  orders  on behalf of other
clients  may be useful to the Manager in carrying  out its  obligations  to the
Company.  While such research is available to and may be used by the Manager in
providing  investment  advice to all its clients  (including  affiliates of the
Manager),  not all of such  research may be used by the Manager for the benefit
of the Company.  Such  research and services  will be in addition to and not in
lieu of research and services provided by the Manager,  and the expenses of the
Manager  will not  necessarily  be reduced by the receipt of such  supplemental
research.  See THE  COMPANY'S  MANAGER.  

Securities of the same issuer may be purchased,  held, or sold at the same time
by the Company for any or all of its Funds,  or other accounts or companies for
which the Manager acts as the investment adviser  (including  affiliates of the
Manager).  On  occasions  when the  Manager  deems  the  purchase  or sale of a
security to be in the best  interest of the Company,  as well as the  Manager's
other  clients,  the Manager,  to the extent  permitted by applicable  laws and
regulations,  may  aggregate  such  securities  to be sold or purchased for the
Company  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  Manager  in the  manner it
considers to be most equitable and consistent with its fiduciary obligations to
all such customers,  including the Company.  In some instances,  this procedure
may impact the price and size of the position obtainable for the Company.

PORTFOLIO  TURNOVER  RATES 

The rate of portfolio  turnover will not be a limiting  factor when the Manager
deems  changes in each  Fund's  portfolio  appropriate  in view of each  Fund's
investment  objective.  Although  neither Fund will purchase or sell securities
solely to achieve  short-term  trading  profits,  each Fund may sell  portfolio
securities  without  regard to the length of time held if consistent  with each
Fund's  investment  objective.  A higher  degree  of  portfolio  activity  will
increase brokerage costs to a Fund.
   
     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,  short-term  U.S.  Government  securities,  and variable rate securities
(those  securities  with put date  intervals  of less  than one  year)  are not
considered when computing the turnover rate.

                         FURTHER DESCRIPTION OF SHARES

The Company is  authorized  to issue  shares in separate  series or Funds.  Ten
Funds have been established,  two of which are described in this SAI. Under the
Articles of  Incorporation,  the Board of Directors 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
such 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 Company not readily  identifiable as
belonging  to a  particular  Fund are  allocated  on the  basis of each  Fund's
relative net assets during the fiscal year or in such other manner as the Board
determines  to be fair and  equitable.  Each share of each Fund  represents  an
equal  proportionate  interest  in that  Fund  with  every  other  share and is
entitled to such dividends and  distributions out of the net income and capital
gains  belonging to that Fund when declared by the Board.  

     Under the  provisions of the Bylaws of the Company,  no annual  meeting of
shareholders is required. Thus, there will ordinarily be no shareholder meeting
unless  required  by  the  1940  Act.  Under  certain  circumstances,  however,
shareholders  may apply for  shareholder  information  to obtain  signatures to
request a special shareholder meeting. Moreover,  pursuant to the Bylaws of the
Company,  any Director may be removed by the affirmative  vote of a majority of
the outstanding  Company shares;  and holders of 10% or more of the outstanding
shares of the Company can require  Directors to call a meeting of  shareholders
for the  purpose  of voting on the  removal  of one or more  Directors.  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 net asset values of the Fund's shares.  However,  on
matters  affecting an individual  Fund, a separate vote of the  shareholders of
that Fund is required.  Shareholders  of a Fund are not entitled to vote on any
matter  which does not affect that Fund but which  requires a separate  vote of
another Fund.  Shares do not have  cumulative  voting rights,  which means that
holders of more than 50% of the shares voting for the election of Directors can
elect 100% of the Company's  Board of  Directors,  and the holders of less than
50% of the shares  voting for the  election  of  Directors  will not be able to
elect any person as a Director.
    
     Shareholders of a particular Fund might have the power to elect all of the
Directors  of the  Company  because  that  Fund  has a  majority  of the  total
outstanding  shares of the Company.  When issued,  each Fund's shares are fully
paid and  nonassessable,  have no pre-emptive or subscription  rights,  and are
fully transferable. There are no conversion rights.

                               TAX CONSIDERATIONS

Each Fund intends to qualify as a regulated investment company under Subchapter
M of the  Internal  Revenue Code of 1986,  as amended (the Code).  Accordingly,
each  Fund will not 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.
     
     To qualify as a regulated investment company,  each 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), (2) derive in each taxable year less
than 30% of its gross  income  from the sale or other  disposition  of stock or
securities held less than three months (the 30% test),  and (3) satisfy certain
diversification requirements at the close of each quarter of the Fund's taxable
year. 

     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  twelve-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. 
   
     Taxable  distributions  are generally  included in a  shareholder's  gross
income for the taxable year in which they are received.  Dividends  declared in
October,  November,  or December and made payable to  shareholders of record in
such a month will be deemed to have been  received on December  31, if the Fund
pays the dividend  during the following  January.  If a  shareholder  of a Fund
receives a  distribution  taxable as  long-term  capital  gain with  respect to
shares of a Fund and redeems or exchanges  the shares before he or she has held
them for more than six months,  any loss on the redemption or exchanges that is
less  than or  equal to the  amount  of the  distribution  will be  treated  as
long-term capital loss.

______________________
  
  *  Effective  December 31, 1996,  George E. Brown  retired as a Director from
     the Board of Directors.

(a)  Robert  G.  Davis,  Michael  J.C.  Roth,  and John W.  Saunders,  Jr.  are
     affiliated with the Company's investment adviser,  IMCO, and, accordingly,
     receive  no  remuneration  from the  Company or any other Fund of the USAA
     Family of Funds.

(b)  At July 31, 1997,  the USAA Family of Funds  consisted of four  registered
     investment companies offering 33 individual funds. Each Director presently
     serves as a Director  or Trustee  of each  investment  company in the USAA
     Family of Funds.  In addition,  Michael J.C.  Roth  presently  serves as a
     Trustee of USAA Life  Investment  Trust, a registered  investment  company
     advised by IMCO, consisting of seven funds offered to investors in a fixed
     and variable annuity contract with USAA Life Insurance  Company.  Mr. Roth
     receives no compensation as Trustee of USAA Life Investment  Trust. 

    All of the above Directors are also  Directors/Trustees  of the other funds
within the USAA  Family of Funds.  No  compensation  is paid by any fund to any
Director/Trustee  who is a  director,  officer,  or  employee  of  IMCO  or its
affiliates.  No  pension or  retirement  benefits  are  accrued as part of fund
expenses.  The Company reimburses certain expenses of the Directors who are not
affiliated  with the investment  adviser.  As of January 31, 1998, the officers
and Directors of the Company and their  families as a group owned  beneficially
or of record less than 1% of the outstanding shares of the Company.

     As of January 31, 1998,  USAA and its affiliates  owned  2,000,010  shares
(27.5%) of the Science & Technology  Fund and 2,000,010  shares  (85.7%) of the
First Start Growth Fund.

     The Company knows of no other persons who, as of January 31, 1998, held of
record or owned  beneficially  5% or more of the Science & Technology and First
Start Growth Funds' shares.
    
                             THE COMPANY'S MANAGER

As described in each Fund's Prospectus,  USAA Investment  Management Company is
the Manager and  investment  adviser,  providing  services  under the  Advisory
Agreement.  The Manager was  organized in May 1970 and has served as investment
adviser and  underwriter  for USAA Mutual Fund,  Inc.  from its  inception.  
   
     In addition to managing  the  Company's  assets,  the Manager  advises and
manages the investments for USAA and its affiliated  companies as well as those
of USAA Tax Exempt Fund,  Inc., USAA Investment  Trust, and USAA State Tax-Free
Trust, and USAA Life Investment Trust. As of the date of this SAI, total assets
under  management  by the Manager  were  approximately  $36  billion,  of which
approximately $22 billion were in mutual fund portfolios.
    
                                      11
<PAGE>

ADVISORY AGREEMENT

Under the  Advisory  Agreement,  the Manager  provides an  investment  program,
carries out the investment  policy,  and manages the portfolio  assets for each
Fund.  The  Manager  is  authorized,  subject  to the  control  of the Board of
Directors of the Company,  to determine the selection,  amount, and time to buy
or sell securities for each Fund. In addition to providing investment services,
the  Manager  pays  for  office  space,  facilities,  business  equipment,  and
accounting  services (in addition to those  provided by the  Custodian) for the
Company. The Manager compensates all personnel,  officers, and Directors of the
Company if such persons are also  employees  of the Manager or its  affiliates.
For these services under the Advisory Agreement,  the Company has agreed to pay
the Manager a fee computed as described  under FUND  MANAGEMENT  in each Fund's
Prospectus.  Management  fees are  computed  and accrued  daily and are payable
monthly.  
   
     Except for the services and facilities provided by the Manager,  each Fund
pays all other expenses incurred in its operation. Expenses for which each Fund
is  responsible  includes  taxes (if any);  brokerage  commissions on portfolio
transactions (if any);  expenses of issuance and redemption of shares;  charges
of transfer  agents,  custodians,  and  dividend  disbursing  agents;  costs of
preparing  and  distributing  proxy  material,  costs of printing and engraving
stock   certificates;   auditing  and  legal  expenses;   certain  expenses  of
registering  and  qualifying  shares for sale;  fees of  Directors  who are not
interested  persons  (not  affiliated)  of the  Manager;  costs of printing and
mailing the Prospectus, SAI, and periodic reports to existing shareholders; and
any other  charges or fees not  specifically  enumerated.  The Manager pays the
cost of printing and mailing copies of the Prospectus,  the SAI, and reports to
prospective  shareholders.  
    
     The Advisory Agreement will remain in effect until June 30, 1998, for each
Fund and will  continue  in effect from year to year  thereafter  for each such
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
Directors  (on behalf of such Fund)  including a majority of the  Directors who
are not interested  persons of the Manager or (otherwise  than as Directors) of
the Company,  at a meeting  called for the purpose of voting on such  approval.
The Advisory  Agreement  may be terminated at any time by either the Company or
the Manager on 60 days' written notice. It will automatically  terminate in the
event of its assignment (as defined in the 1940 Act).  

UNDERWRITER  

The Company has an agreement  with the Manager for exclusive  underwriting  and
distribution  of each Fund's shares on a continuing  best efforts  basis.  This
agreement  provides that the Manager will receive no fee or other  compensation
for such distribution services.

TRANSFER AGENT 

The Transfer  Agent  performs  transfer  agent services for the Company under a
Transfer Agency Agreement.  Services include maintenance of shareholder account
records,  handling of communications  with  shareholders,  distribution of Fund
dividends,  and  production  of reports  with  respect to account  activity for
shareholders  and the  Company.  For its  services  under the  Transfer  Agency
Agreement,  each Fund pays the Transfer Agent an annual fixed fee of $23.50 per
account. This fee is subject to change at any time.

The fee to the Transfer  Agent  includes  processing  of all  transactions  and
correspondence.  Fees are billed on a monthly basis at the rate of  one-twelfth
of the annual fee. In addition,  each Fund pays all  out-of-pocket  expenses of
the  Transfer  Agent and other  expenses  which are  incurred  at the  specific
direction of the Company.

                        CALCULATION OF PERFORMANCE DATA

Information  regarding total return of each Fund is provided under  PERFORMANCE
INFORMATION  in its  Prospectus.  See  VALUATION  OF  SECURITIES  herein  for a
discussion of the manner in which the Funds' price per share is calculated.

TOTAL RETURN 

Each Fund may advertise performance in terms of average annual total return for
1-, 5-, and 10-year periods, or for such lesser periods as the Fund has 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:
                                                           
                                P(1 + T)N = ERV

     Where:     P   =  a hypothetical initial payment of $1,000
                T   =  average annual total return
                n   =  number of years
              ERV   =  ending redeemable value of a hypothetical $1,000 payment
                       made at the  beginning of the 1-, 5-, or 10-year periods
                       at the end of the year or period

     The  calculation  assumes any charges are deducted from the initial $1,000
payment and assumes all dividends and  distributions by the Fund are reinvested
at the price  stated in the  Prospectus  on the  reinvestment  dates during the
period,  and includes all  recurring  fees that are charged to all  shareholder
accounts.

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

1. LONG-TERM DEBT RATINGS:                   

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

Aaa      Bonds which 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  which 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 which 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 which suggest a  susceptibility  to impairment
         sometime in the future.

Baa      Bonds which 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.

Ba       Bonds  which are rated Ba are  judged  to have  speculative  elements;
         their  future  cannot  be  considered  as  well  assured.   Often  the
         protection  of interest and principal  payments may be very  moderate,
         and thereby not well  safeguarded  during both good and bad times over
         the future. Uncertainty of position characterizes bonds in this class.

B        Bonds  which  are  rated  B  generally  lack  characteristics  of  the
         desirable investment.  Assurance of interest and principal payments or
         of  maintenance of other terms of the contract over any long period of
         time may be small.

Caa      Bonds which are rated Caa are of poor standing.  Such issues may be in
         default or there may be present  elements  of danger  with  respect to
         principal or interest.

Ca       Bonds which are rated Ca represent  obligations  which are speculative
         in a high  degree.  Such  issues  are often in  default  or have other
         marked shortcomings.

C        Bonds  which  are rated C are the  lowest  rated  class of bonds,  and
         issues so rated can be regarded as having  extremely poor prospects of
         ever attaining any real investment standing.

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

AAA      Debt rated AAA has the highest  rating  assigned by Standard & Poor's.
         Capacity to pay interest and repay principal is extremely strong.

AA       Debt rated AA has a very  strong  capacity to pay  interest  and repay
         principal  and  differs  from the highest  rated  issues only in small
         degree.

A        Debt rated A has a strong capacity to pay interest and repay principal
         although it is somewhat  more  susceptible  to the adverse  effects of
         changes in circumstances  and economic  conditions than debt in higher
         rated categories.

BBB      Debt  rated BBB is  regarded  as having an  adequate  capacity  to pay
         interest and repay principal.  Whereas it normally  exhibits  adequate
         protection   parameters,   adverse  economic  conditions  or  changing
         circumstances  are more  likely to lead to a weakened  capacity to pay
         interest and repay  principal for debt in this category than in higher
         rated categories.

BB       Debt rated BB has less near-term  vulnerability  to default than other
         speculative issues.  However, it faces major ongoing  uncertainties or
         exposure to adverse business,  financial, or economic conditions which
         could  lead  to  inadequate  capacity  to  meet  timely  interest  and
         principal  payments.  The BB  rating  category  is also  used for debt
         subordinated to senior debt that is assigned an actual or implied BBB-
         rating.

B        Debt rated B has a greater  vulnerability to default but currently has
         the  capacity to meet  interest  payments  and  principal  repayments.
         Adverse business, financial, or economic conditions will likely impair
         capacity or  willingness  to pay interest and repay  principal.  The B
         rating category is also used for debt subordinated to senior debt that
         is assigned an actual or implied BB or BB- rating.

CCC      Debt rated CCC has a currently identifiable  vulnerability to default,
         and is dependent  upon  favorable  business,  financial,  and economic
         conditions  to meet  timely  payment  of  interest  and  repayment  of
         principal.  In the event of adverse business,  financial,  or economic
         conditions,  it is not likely to have the capacity to pay interest and
         repay  principal.  The CCC  rating  category  is also  used  for  debt
         subordinated to senior debt that is assigned an actual or implied B or
         B- rating.

CC       The rating CC typically is applied to debt subordinated to senior debt
         that is  assigned  an actual or  implied  CCC  rating.  C The rating C
         typically  is applied  to debt  subordinated  to senior  debt which is
         assigned an actual or implied  CCC- debt  rating.  The C rating may be
         used to cover a situation where a bankruptcy  petition has been filed,
         but debt service payments are continued.  

CI       The rating CI is  reserved  for income  bonds on which no  interest is
         being  paid.  

D        Debt rated D is in payment default. The D rating category is used when
         interest  payments or principal  payments are not made on the date due
         even if the  applicable  grace  period  has not  expired,  unless  S&P
         believes that such payments will be made during such grace period. The
         D rating also will be used upon the filing of a bankruptcy petition if
         debt  service  payments  are  jeopardized.  

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 INVESTORS SERVICE, INC. (FITCH)

AAA      Bonds  considered  to be  investment  grade and of the highest  credit
         quality.  The  obligor  has an  exceptionally  strong  ability  to pay
         interest  and repay  principal,  which is  unlikely  to be affected by
         reasonably  foreseeable  events.  

AA       Bonds  considered  to be  investment  grade  and of very  high  credit
         quality.  The obligor's ability to pay interest and repay principal is
         very strong,  although not quite as strong as bonds rated AAA. Because
         bonds  rated  in the  AAA  and AA  categories  are  not  significantly
         vulnerable to  foreseeable  future  developments,  short-term  debt of
         these  issuers is  generally  rated  F-1+.  

A        Bonds  considered to be investment  grade and of high credit  quality.
         The  obligor's   ability  to  pay  interest  and  repay  principal  is
         considered to be strong, but may be more vulnerable to adverse changes
         in  economic  conditions  and  circumstances  than bonds  with  higher
         ratings.  

BBB      Bonds  considered to be investment  grade and of  satisfactory  credit
         quality.  The obligor's ability to pay interest and repay principal is
         considered to be adequate.  Adverse changes in economic conditions and
         circumstances,  however,  are more  likely to have  adverse  impact on
         these bonds, and therefore, impair timely payment. The likelihood that
         the ratings of these bonds will fall below  investment grade is higher
         than for bonds with higher  ratings.

POSITION OF A CREDIT WITHIN THE RATING CATEGORY. PLUS AND MINUS SIGNS, HOWEVER,
ARE NOT USED IN THE AAA CATEGORY.
    
DUFF & PHELPS (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
         more 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 TAXABLE DEBT 

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:   

         o  Leading market positions in well-established industries.  
         o  High rates of return on funds employed.  
         o  Conservative  capitalization  structure  with  moderate reliance on
            debt and ample asset protection.  
         o  Broad margins in  earnings coverage of  fixed financial charges and
            high internal cash generation.    
         o  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 

MIG 1/VMIG 1  This  designation  denotes best quality.  There is present strong
              protection by established cash flows,  superior liquidity support
              or demonstrated broadbased 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. 

MIG 3/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 COMMERCIAL PAPER 

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.  

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.  

                                      15

S&P NOTES

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 

F-1+     Exceptionally  strong credit quality.  Issues assigned this rating are
         regarded  as having  the  strongest  degree of  assurance  for  timely
         payment.  

F-1      Very strong credit  quality.  Issues  assigned this rating  reflect an
         assurance for timely  payment only slightly less in degree than issues
         rated F-1+. 

F-2      Good credit  quality.  Issues assigned this rating have a satisfactory
         degree of assurance  for timely  payment,  but the margin of safety is
         not as great as for issues assigned F-1+ and F-1 ratings.  

F-3      Fair credit quality.  Issues assigned this rating have characteristics
         suggesting  that  the  degree  of  assurance  for  timely  payment  is
         adequate;   however,  near-term  adverse  changes  could  cause  these
         securities to be rated below investment grade. 

DUFF & PHELPS INC. 

D-1+     Highest certainty of timely payment.  Short-term liquidity,  including
         internal  operating  factors and/or 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 issues as
         to  investment  grade.  Risk  factors  are larger and  subject to more
         variation. Nevertheless, timely payment is expected.   

THOMPSON BANKWATCH, INC.  

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.
         
IBCA INC. 

A1       Obligations  supported by the highest  capacity for timely  repayment.
         Where issues possess a particularly strong credit feature, a rating of
         A1+ is assigned.  

A2       Obligations  supported by a satisfactory capacity for timely repayment
         although  such  capacity  may be  susceptible  to  adverse  changes in
         business, economic, or financial conditions.

A3       Obligations  supported by an adequate  capacity for timely  repayment.
         Such  capacity is more  susceptible  to adverse  changes in  business,
         economic,  or  financial  conditions  than for  obligations  in higher
         categories.  

B        Obligations for which the capacity for timely repayment is susceptible
         to adverse changes in business, economic, or financial conditions.

C        Obligations  for which  there is a high risk of  default  or which are
         currently in default.

                       APPENDIX C - DOLLAR-COST AVERAGING

Dollar-cost  averaging  is a systematic  investing  method which can be used by
investors as a disciplined technique for investing.  A fixed amount of money is
invested in a security (such as a stock or mutual fund) on a regular basis over
a period of time,  regardless  of whether  securities  markets are moving up or
down.  

     This  practice  reduces  average  share costs to the investor who acquires
more shares in periods of lower  securities  prices and fewer shares in periods
of higher prices.  

     While  dollar-cost  averaging does not assure a profit or protect  against
loss in declining markets, this investment strategy is an effective way to help
calm the effect of fluctuations in the financial markets.  Systematic investing
involves  continuous  investment in securities  regardless of fluctuating price
levels of such securities. Investors should consider their financial ability to
continue purchases through periods of low and high price levels.  

     As the following chart  illustrates,  dollar-cost  averaging tends to keep
the overall cost of shares lower.  This example is for  illustration  only, and
different trends would result in different average costs.

Item 27.      INDEMNIFICATION

              Protection for the liability of the adviser and  underwriter  and
              for the officers and  directors of the  Registrant is provided by
              two methods:

        (a)   THE DIRECTOR AND OFFICER LIABILITY POLICY. This policy covers all
              losses   incurred  by  the   Registrant,   its  adviser  and  its
              underwriter from any claim made against those entities or persons
              during the policy period by any shareholder or former shareholder
              of the Fund by  reason of any  alleged  negligent  act,  error or
              omission  committed in connection with the  administration of the
              investments of said  Registrant or in connection with the sale or
              redemption of shares issued by said Registrant.

        (b)   STATUTORY INDEMNIFICATION PROVISIONS.  Under Section 2-418 of the
              Maryland General Corporation  Law, the  Registrant is  authorized
              to  indemnify  any past or present  director,  officer,  agent or
              employee against  judgments,  penalties,  fines,  settlements and
              reasonable  expenses  actually incurred by him in connection with
              any  proceeding in which he is a party by reason of having served
              as a director,  officer,  agent or employee,  if he acted in good
              faith and reasonably believed that, (i) in the case of conduct in
              his official  capacity with the Registrant,  that his conduct was
              in the best  interests  of the  Registrant,  or (ii) in all other
              cases,  that his  conduct  was at least not  opposed  to the best
              interests  of  the  Registrant.  In  the  case  of  any  criminal
              proceeding,  said  director,  officer,  agent or employee must in
              addition have had no reasonable cause to believe that his conduct
              was  unlawful.  In the case of a proceeding by or in the right of
              the  Registrant,   indemnification   may  only  be  made  against
              reasonable  expenses  and  may  not be  made  in  respect  of any
              proceeding  in which the  director,  officer,  agent or  employee
              shall  have been  adjudged  to be liable to the  Registrant.  The
              termination  of any  proceeding by judgment,  order,  settlement,
              conviction,  or upon a plea of nolo  contendere or its equivalent
              creates a  rebuttable  presumption  that the  director,  officer,
              agent or employee did not meet the requisite  standard of conduct
              for indemnification. No indemnification may be made in respect of
              any  proceeding   charging   improper  personal  benefit  to  the
              director,  officer,  agent or employee  whether or not  involving
              action in such  person's  official  capacity,  if such person was
              adjudged to be liable on the basis that improper personal benefit
              was received.  If such  director,  officer,  agent or employee is
              successful,  on the merits or  otherwise,  in defense of any such
              proceeding  against  him,  he shall be  indemnified  against  the

                                      C-5
<PAGE>

              reasonable expenses incurred by him (unless such  indemnification
              is  limited  by  the  Registrant's  charter,  which  it is  not).
              Additionally,  a court  of  appropriate  jurisdiction  may  order
              indemnification in certain  circumstances even if the appropriate
              standard of conduct set forth above was not met.

              Indemnification may not be made unless authorized in the specific
              case after  determination that the applicable standard of conduct
              has been met. Such determination shall be made by either: (i) the
              board of  directors  by either  (x) a  majority  vote of a quorum
              consisting of directors  not parties to the  proceeding or (y) if
              such a quorum  cannot be obtained,  then by a majority  vote of a
              committee of the board consisting solely of two or more directors
              not  at the  time  parties  to  such  proceeding  who  were  duly
              designated  to act in the matter by a  majority  vote of the full
              board in which  the  designated  directors  who are  parties  may
              participate;  (ii) special legal counsel selected by the board of
              directors or a committee of the board by vote as set forth in (i)
              above,  or,  if the  requisite  quorum  of the  board  cannot  be
              obtained therefore and the committee cannot be established,  by a
              majority  vote of the  full  board  in  which  directors  who are
              parties may participate; or (iii) the stockholders.

              Reasonable  expenses may be reimbursed or paid by the  Registrant
              in  advance  of  final   disposition  of  a  proceeding  after  a
              determination,  made in accordance  with the procedures set forth
              in the  preceding  paragraph,  that the facts then known to those
              making the determination would not preclude indemnification under
              the applicable  standards provided the Registrant  receives (i) a
              written  affirmation  of the  good  faith  belief  of the  person
              seeking  indemnification  that the applicable standard of conduct
              necessary  for  indemnification  has been met, and (ii) a written
              undertaking  to  repay  the  advanced  sums  if it is  ultimately
              determined  that the applicable  standard of conduct has not been
              met.

              Insofar as  indemnification  for  liabilities  arising  under the
              Securities  Act of 1933 may be permitted to  directors,  officers
              and  controlling  persons  of  the  Registrant  pursuant  to  the
              Registrant's   Articles  of  Incorporation   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 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 director, officer or
              controlling person of the Registrant in the successful defense of
              any action,  suit or  proceeding)  is asserted by such  director,
              officer or controlling  person in connection  with the securities
              being registered, then 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  whether  indemnification  by it is  against  public
              policy as  expressed in the Act and will be governed by the final
              adjudication of such issue.

Item 28.      BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER

              Information  pertaining to business and other  connections of the
              Registrant's   investment  adviser  is  hereby   incorporated  by
              reference  to the  section  of  the  Prospectus  captioned  "Fund

January 13, 1998


USAA Mutual Fund, Inc.,
USAA Investment Trust,
USAA Tax Exempt Fund, Inc., and
USAA State Tax-Free Trust, on behalf of and for the
benefit of the series
of funds comprising each such Borrower
as set forth on Schedule A hereto
9800 Fredericksburg Road
San Antonio, Texas 78288

Attention: Michael J.C. Roth, President

Gentlemen:

This  Facility  Agreement  Letter (this  "Agreement")  sets forth the terms and
conditions  for loans (each a "Loan" and  collectively  the "Loans") which USAA
Capital  Corporation  ("CAPCO")  may from time to time make  during  the period
commencing January 13, 1998 and ending January 12, 1999 (the "Facility Period")
to USAA Mutual Fund, Inc., USAA Investment  Trust,  USAA Tax Exempt Fund, Inc.,
and USAA State Tax-Free Trust,  and each investment  company which may become a
party hereto  pursuant to the terms of this  Agreement  (each a "Borrower"  and
collectively  the  "Borrowers"),  each of which is executing  this Agreement on
behalf  of and for the  benefit  of the  series of funds  comprising  each such
Borrower as set forth on Schedule A hereto (as hereafter modified or amended in
accordance with the terms hereof) (each a "Fund" and collectively the "Funds"),
under a master  revolving  credit  facility (the  "Facility").  USAA Investment
Management  Company is the Manager and  Investment  Advisor of each Fund.  This
Agreement replaces in its entirety that certain Facility Agreement Letter dated
January 14, 1997,  between the  Borrowers  and CAPCO.  CAPCO and the  Borrowers
hereby agree as follows:

     1.  AMOUNT.  The  aggregate  principal  amount of the  Loans  which may be
advanced  under this Facility  shall not exceed,  at any one time  outstanding,
Seven Hundred Fifty Million  Dollars  ($750,000,000).  The aggregate  principal
amount of the Loans which may be  borrowed  by a Borrower  for the benefit of a
particular  Fund under this Facility shall not exceed the borrowing  limit (the
"Borrowing  Limit") on  borrowings  applicable  to such  Fund,  as set forth on
Schedule A hereto.

     2. PURPOSE AND  LIMITATIONS  ON  BORROWINGS.  Each  Borrower  will use the
proceeds of each Loan made to it solely for temporary or emergency  purposes of
the Fund for whose  benefit it is  borrowing  in  accordance  with such  Fund's
Borrowing Limit (Schedule A) and prospectus in effect at the time of such Loan.
Portfolio  securities  may not be  purchased  by a Fund  while  there is a Loan
outstanding  under the Facility or any other facility,  if the aggregate 

<PAGE>

amount of such Loan and any other such loan  exceeds 5% of the total  assets of
such Fund.

     3.  BORROWING  RATE AND  MATURITY  OF  LOANS.  CAPCO  may make  Loans to a
Borrower and the principal  amount of the Loans  outstanding  from time to time
shall  bear  interest  at a rate per  annum  equal  to the rate at which  CAPCO
obtains funding in the capital markets plus a standard mark-up to cover CAPCO's
operating costs (not to exceed 8 basis points).  Interest on the Loans shall be
calculated  on the basis of a year of 360 days and the actual days  elapsed but
shall not exceed the highest lawful rate.  Each loan will be for an established
number  of  days   agreed   upon  by  the   applicable   Borrower   and  CAPCO.
Notwithstanding the above, all Loans to a Borrower shall be made available at a
rate per annum equal to the rate at which CAPCO would make loans to  affiliates
and  subsidiaries.  Further,  if the  CAPCO  rate  exceeds  the rate at which a
Borrower  could  obtain  funds  pursuant  to the  NationsBank  of  Texas,  N.A.
("NationsBank")  364-  day  committed   $100,000,000  Master  Revolving  Credit
Facility,  the  Borrower  will in the absence of  predominating  circumstances,
borrow from  NationsBank.  Any past due principal and/or accrued interest shall
bear  interest at a rate per annum equal to the  aggregate of the Federal Funds
Rate plus 1 percent (100 basis points) and shall be payable on demand.

     4. ADVANCES,  PAYMENTS,  PREPAYMENTS AND READVANCES.  Upon each Borrower's
request,  and subject to the terms and conditions  contained herein,  CAPCO may
make Loans to each Borrower on behalf of and for the benefit of its  respective
Fund(s) during the Facility  Period,  and each Borrower may at CAPCO's sole and
absolute  discretion,  borrow,  repay and reborrow funds  hereunder.  The Loans
shall be evidenced by a duly executed and delivered Master Grid Promissory Note
in the form of Exhibit A. Each Loan  shall be in an  aggregate  amount not less
than One Hundred Thousand United States Dollars (U.S.  $100,000) and increments
of One Thousand United States Dollars (U.S. $1,000) in excess thereof.  Payment
of principal and interest due with respect to each Loan shall be payable at the
maturity of such Loan and shall be made in funds immediately available to CAPCO
prior to 2 p.m.  San Antonio  time on the day such  payment is due, or as CAPCO
shall  otherwise  direct  from  time to time  and,  subject  to the  terms  and
conditions  hereof,  may  be  repaid  with  the  proceeds  of a  new  borrowing
hereunder. Notwithstanding any provision of this Agreement to the contrary, all
Loans, accrued but unpaid interest and other amounts payable hereunder shall be
due and payable upon  termination of the Facility  (whether by  acceleration or
otherwise).

     5. FACILITY FEE. As this Facility is uncommitted, no facility fee shall be
charged by CAPCO.

     6. OPTIONAL TERMINATION.  The Borrowers shall have the right upon at least
three (3)  business  days  prior  written  notice to CAPCO,  to  terminate  the
Facility.

     7. MANDATORY TERMINATION OF THE FACILITY. The Facility, unless extended by
written  amendment,  shall  automatically  terminate  on  the  last  day of the
Facility Period and any Loans then outstanding  (together with accrued interest
thereon and any other amounts owing hereunder) shall be due and payable on such
date.

                                       2
<PAGE>

     8. UNCOMMITTED FACILITY. The Borrowers acknowledge that the Facility is an
uncommitted  facility and that CAPCO shall have no  obligation to make any Loan
requested during the Facility Period under this Agreement. Further, CAPCO shall
not make any Loan if this Facility has been terminated by the Borrowers,  or if
at the time of a request for a Loan by a Borrower (on behalf of the  applicable
Fund(s)) there exists any Event of Default or condition which, with the passage
of time or giving of notice,  or both,  would  constitute or become an Event of
Default with respect to such Borrower (or such applicable Fund(s)).

     9. LOAN  REQUESTS.  Each  request for a Loan (each a  "Borrowing  Notice")
shall be in writing by the applicable Borrower(s), except that such Borrower(s)
may make an oral  request  (each an "Oral  Request")  provided  that  each Oral
Request  shall be followed by a written  Borrowing  Notice  within one business
day. Each Borrowing  Notice shall specify the following  terms ("Terms") of the
requested  Loan:  (i) the date on which such Loan is to be disbursed,  (ii) the
principal amount of such Loan,  (iii) the Borrower(s)  which are borrowing such
Loan and the  amount of such Loan to be  borrowed  by each  Borrower,  (iv) the
Funds for whose  benefit the loan is being  borrowed and the amount of the Loan
which is for the benefit of each such Fund, and (v) the requested maturity date
of the Loan.  Each  Borrowing  Notice  shall also set forth the total assets of
each Fund for whose  benefit a portion of the Loan is being  borrowed as of the
close of business on the day  immediately  preceding the date of such Borrowing
Notice.  Borrowing notices shall be delivered to CAPCO by 9:00 a.m. San Antonio
time on the day the Loan is requested to be made.

Each  Borrowing  Notice  shall  constitute  a  representation  to  CAPCO by the
applicable  Borrower(s)  that  all of the  representations  and  warranties  in
Section  12 hereof  are true and  correct  as of such date and that no Event of
Default or other  condition which with the passage of time or giving of notice,
or both, would result in an Event of Default, has occurred or is occurring.

     10. CONFIRMATIONS;  CREDITING OF FUNDS; RELIANCE BY CAPCO. Upon receipt by
CAPCO of a Borrowing Notice:

         (a) CAPCO shall provide each applicable Borrower written  confirmation
of the Terms of such Loan via  facsimile  or  telecopy,  as soon as  reasonably
practicable;  provided, however, that the failure to do so shall not affect the
obligation of any such Borrower;

         (b)  CAPCO  shall  make  such  Loan in  accordance  with the  Terms by
transfer of the Loan amount in immediately  available  funds, to the account of
the  applicable  Borrower(s)  as specified in Exhibit B to this Agreement or as
such  Borrower(s)  shall  otherwise  specify to CAPCO in a writing signed by an
Authorized Individual (as defined in Section 11) of such Borrower(s); and

<PAGE>

         (c) CAPCO shall make appropriate entries on the Note or the records of
CAPCO to reflect the Terms of the Loan; provided,  however, that the failure to
do so shall not affect the obligation of any Borrower.

CAPCO  shall be entitled  to rely upon and act  hereunder  pursuant to any Oral
Request  which it  reasonably  believes  to have  been  made by the  applicable
Borrower through an Authorized  Individual.  If any Borrower  believes that the
confirmation  relating to any Loan contains any error or  discrepancy  from the
applicable Oral Request, such Borrower will promptly notify CAPCO thereof.

     11. BORROWING RESOLUTIONS AND OFFICERS  CERTIFICATES.  Prior to the making
of any Loan pursuant to this  Agreement,  the Borrowers shall have delivered to
CAPCO (a) the duly executed Note, (b) Resolutions of each  Borrower's  Trustees
or Board of Directors authorizing such Borrower to execute, deliver and perform
this Agreement and the Note on behalf of the applicable Funds, (c) an Officer's
Certificate in substantially the form set forth in Exhibit D to this Agreement,
authorizing certain individuals ("Authorized  Individuals"),  to take on behalf
of each Borrower (on behalf of the applicable  Funds) actions  contemplated  by
this Agreement and the Note, and (d) the Opinion of Counsel to USAA  Investment
Management Company, Manager and Advisor to the Borrowers,  with respect to such
matters as CAPCO may reasonably request .

     12. REPRESENTATIONS AND WARRANTIES. In order to induce CAPCO to enter into
this  Agreement  and to make the Loans  provided for  hereunder,  each Borrower
hereby  makes with  respect to itself,  and as may be  relevant,  the series of
Funds comprising such Borrower,  the following  representations and warranties,
which shall survive the execution and delivery hereof and of the Note:

         (a)  ORGANIZATION,  STANDING,  ETC. The Borrower is a  corporation  or
trust duly organized,  validly existing,  and in good standing under applicable
state laws and has all  requisite  corporate  or trust power and  authority  to

         (b) FINANCIAL INFORMATION; DISCLOSURE, ETC. The Borrower has furnished

prepared in accordance with generally accepted accounting principles applied on
a consistent  basis and fairly  present the  financial  position and results of
operations of such Borrower and the  applicable  Funds on the dates and for the
periods indicated. Neither this Agreement nor any financial statements, reports
or other documents or  certificates  furnished to CAPCO by such Borrower or the
applicable  Funds in  connection  with  the  transactions  contemplated  hereby
contain any untrue  statement of a material  fact or omit to state any material
fact necessary to make the statements  contained  herein or therein in light of
the circumstances when made not misleading;

                                       4
<PAGE>

         (c) AUTHORIZATION;  COMPLIANCE WITH OTHER INSTRUMENTS.  The execution,
delivery  and  performance  of this  Agreement  and the  Note,  and  borrowings
hereunder, have been duly authorized by all necessary corporate or trust action
of the Borrower and will not result in any  violation of or be in conflict with
or  constitute  a  default  under  any term of the  charter,  by- laws or trust
agreement  of  such  Borrower  or the  applicable  Funds,  or of any  borrowing
restrictions  or  prospectus  or statement of  additional  information  of such
Borrower or the applicable  Funds, or of any agreement,  instrument,  judgment,
decree,  order,  statute,  rule or governmental  regulation  applicable to such
Borrower,  or  result  in  the  creation  of  any  mortgage,  lien,  charge  or
encumbrance  upon any of the  properties  or  assets  of such  Borrower  or the
applicable  Funds  pursuant to any such term.  The Borrower and the  applicable
Funds are not in violation of any term of their respective charter,  by-laws or
trust  agreement,  and  such  Borrower  and  the  applicable  Funds  are not in
violation of any material term of any agreement or instrument to which they are
a party, or to the best of such Borrower's knowledge, of any judgment,  decree,
order, statute, rule or governmental regulation applicable to them;

         (d) SEC  COMPLIANCE.  The  Borrower  and the  applicable  Funds are in
compliance in all material  respects  with all federal and state  securities or
similar laws and  regulations,  including all material  rules,  regulations and
administrative orders of the Securities and Exchange Commission (the "SEC") and

         (e) LITIGATION.  There is no action, suit or proceeding pending or, to
the best of the Borrower's  knowledge,  threatened against such Borrower or the
applicable  Funds in any court or before any  arbitrator or  governmental  body
which seeks to restrain any of the transactions  contemplated by this Agreement
or which, if adversely determined,  could have a material adverse effect on the
assets or business  operations of such Borrower or the applicable  Funds or the
ability of such  Borrower  and the  applicable  Funds to pay and perform  their
obligations hereunder and under the Notes; and

         (f)  BORROWERS'  RELATIONSHIP  TO FUNDS.  The  assets of each Fund for
whose benefit Loans are borrowed by the applicable  Borrower are subject to and
liable for such Loans and are available  (except as  subordinated to borrowings
under the NationsBank  committed  facility) to the applicable  Borrower for the
repayment of such Loans.

     13.  AFFIRMATIVE  COVENANTS  OF THE  BORROWERS.  Until  such time  as  all
amounts of principal  and  interest due to CAPCO by a Borrower  pursuant to any
Loan made to such Borrower is irrevocably  paid in full, and until the Facility
is terminated, such Borrower (for itself and on behalf of its respective Funds)

of the end of such semiannual  period,  as set forth in each  applicable  Funds
Semiannual  Report to shareholders,  together with a calculation of the maximum

         (c) To deliver to CAPCO prompt  notice of the  occurrence of any event

materially  adversely  affect the  ability of any  applicable  Fund to promptly
repay outstanding Loans made for its benefit or the ability of such Borrower to
perform its obligations under this Agreement or the Note;

         (d) To do, or cause to be done,  all things  necessary to preserve and
keep in full force and effect the corporate or trust existence of such Borrower
and all  permits,  rights  and  privileges  necessary  for the  conduct  of its
businesses  and to comply in all material  respects with all  applicable  laws,
regulations and orders, including without limitation, all rules and regulations
promulgated by the SEC;

         (e) To  promptly  notify  CAPCO of any  litigation,  threatened  legal
proceeding or investigation by a governmental  authority which could materially
affect the ability of such Borrower or the  applicable  Funds to promptly repay
the outstanding Loans or otherwise perform their obligations hereunder; and

         (f) In the event a Loan for the  benefit of a  particular  Fund is not
repaid in full  within 10 days  after the date it is  borrowed,  and until such
Loan is repaid in full,  to deliver to CAPCO,  within two  business  days after
each Friday occurring after such 10th day, a statement  setting forth the total
assets of such Fund as of the close of business on each such Friday.

         (g) Upon the  request of CAPCO which may be made by CAPCO from time to
time in the event CAPCO in good faith  believes  that there has been a material
adverse change in the capital markets  generally,  to deliver to CAPCO,  within
two  business  days after such  request,  a statement  setting  forth the total
assets of each Fund for whose benefit a Loan is outstanding on the date of such
request.

     14. NEGATIVE COVENANTS OF THE BORROWERS. Until such time as all amounts of
principal and interest due to CAPCO by a Borrower  pursuant to any Loan made to
such  Borrower  is  irrevocably  paid  in  full,  and  until  the  Facility  is
terminated,  such Borrower (for itself and on behalf of its  respective  Funds)
agrees:

         (a) Not to incur any  indebtedness  for  borrowed  money  (other  than
pursuant to the One Hundred  Million  Dollar  ($100,000,000)  committed  Master
Revolving Credit Facility with  NationsBank and for overdrafts  incurred at the
custodian  of the Funds  from time to time in the  normal  course of  business)
except the Loans,  without the prior  written  consent of CAPCO,  which consent
will not be unreasonably withheld; and

         (b)  Not  to  dissolve  or  terminate  its  existence,   or  merge  or
consolidate with any other person or entity,  or sell all or substantially  all
of its assets in a single transaction or series of related  transactions (other
than assets consisting of margin stock), each without the prior written consent
of CAPCO,  which  consent will not be  unreasonably  withheld;  provided that a
Borrower  may  without  such  consent  merge,  consolidate  with,  or  purchase
substantially all of the assets of, or sell substantially all of its assets to,
an affiliated  investment  company or series  thereof,  as provided for in Rule
17a-8 of the Investment Company Act of 1940.

     15. EVENTS OF DEFAULT.  If any of the following  events (each an "Event of
Default")  shall  occur  (it being  understood  that an Event of  Default  with
respect to one Fund or Borrower  shall not  constitute an Event of Default with
respect to any other Fund or Borrower):

         (a) Any Borrower or Fund shall  default in the payment of principal or
interest  on any Loan or any other fee due  hereunder  for a period of five (5)
days  after the same  becomes  due and  payable,  whether at  maturity  or with
respect to any Facility Fee at a date fixed for the payment thereof;

         (b) Any  Borrower  or Fund  shall  default  in the  performance  of or
compliance  with any term contained in Section 13 hereof and such default shall
not have been remedied  within thirty (30) days after  written  notice  thereof
shall have been given such Borrower or Fund by CAPCO;

         (c) Any  Borrower  or Fund  shall  default  in the  performance  of or
compliance with any term contained in Section 14 hereof;

         (d) Any  Borrower  or  Fund  shall  default  in  the  performance  or
compliance with any other term contained herein and such default shall not have
been remedied  within thirty (30) days after written  notice thereof shall have
been given such Borrower or Fund by CAPCO;

         (e) Any  representation  or warranty made by a Borrower or Fund herein
or 
                                       7
<PAGE>

pursuant  hereto  shall prove to have been false or  incorrect  in any material
respect when made;
 
         (f) An event of default shall occur and be continuing  under any other
facility;  then,  in any  event,  and at any time  thereafter,  if any Event of
Default  shall be  continuing,  CAPCO may by written  notice to the  applicable
Borrower or Fund (i)  terminate  the Facility  with respect to such Borrower or
Fund and (ii) declare the principal and interest in respect of any  outstanding
Loans  with  respect  to such  Borrower  or Fund,  and all  other  amounts  due
hereunder

with  respect to such  Borrower  or Fund,  to be  immediately  due and  payable
whereupon the  principal and interest in respect  thereof and all other amounts
due  hereunder  shall become  forthwith  due and payable  without  presentment,
demand,  protest or other notice of any kind, all of which are expressly waived
by the Borrowers.

     16. NEW BORROWERS;  NEW FUNDS. So long as no Event of Default or condition
which,  with the  passage  of time or the  giving  of  notice,  or both,  would
constitute  or become an Event of Default has occurred and is  continuing,  and
with the  prior  consent  of  CAPCO,  which  consent  will not be  unreasonably
withheld:

         (a) Any  investment  company  that  becomes part of the same "group of
investment  companies"  (as  that  term is  defined  in Rule  11a-3  under  the
Investment  Company Act of 1940) as the original  Borrowers to this  Agreement,
may, by  submitting  an amended  Schedule A and Exhibit B to this  Agreement to
CAPCO (which amended  Schedule A and Exhibit B shall replace the  corresponding
Schedule and Exhibit which are, then a part of this  Agreement)  and such other
documents as CAPCO may reasonably request, become a party to this Agreement and
may become a "Borrower" hereunder; and

         (b) A Borrower may, by submitting an amended  Schedule A and Exhibit B
to this  Agreement  to CAPCO  (which  amended  Schedule  A and  Exhibit B shall
replace the  corresponding  Schedule and Exhibit  which are then a part of this
Agreement),  add  additional  Funds for whose  benefit such Borrower may borrow
Loans.  No such  amendment  of  Schedule A to this  Agreement  shall  amend the
Borrowing Limit applicable to any Fund without the prior approval of CAPCO.

     17.  LIMITED  RECOURSE.  CAPCO  agrees (i) that any claim,  liability,  or
obligation  arising  hereunder  or under the Note  whether  on  account  of the
principal of any Loan,  interest thereon,  or any other amount due hereunder or
thereunder  shall be satisfied  only from the assets of the  specific  Fund for
whose  benefit a Loan is  borrowed  and in any event in an amount not to exceed
the outstanding  principal amount of any Loan borrowed for such Fund's benefit,
together  with  accrued and unpaid  interest  due and owing  thereon,  and such
Fund's  share  of any  other  amount  due  hereunder  and  under  the  Note (as
determined in accordance with the provisions hereof) and (ii) that no assets of
any fund shall be used to satisfy any claim,  liability,  or obligation arising
hereunder or under the Note with respect to the outstanding principal amount of
any Loan  borrowed  for the benefit of any other Fund or any accrued and unpaid
interest  due 

and owing  thereon or such other Fund's share of any other amount due hereunder
and under the Note (as determined in accordance with the provisions hereof).

     18.  REMEDIES ON DEFAULT.  In case any one or more Events of Default shall
occur and be continuing, CAPCO may proceed to protect and enforce its rights by
an action at law, suit in equity or other appropriate proceedings,  against the
applicable  Borrower(s)  and/or  Fund(s),  as the case may be. In the case of a
default  in the  payment of any  principal  or  interest  on any Loan or in the
payment of any fee due hereunder,  the relevant  Fund(s) (to be allocated among
such Funds as the Borrowers deem  appropriate)  shall pay to CAPCO such further
amount as shall be  sufficient  to cover the cost and  expense  of  collection,
including, without limitation, reasonable attorney's fees and expenses.

     19. NO WAIVER OF REMEDIES. No course of  dealing  or  failure or  delay on
the part of CAPCO in exercising any right or remedy hereunder or under the Note
shall  constitute a waiver of any right or remedy  hereunder or under the Note,
nor shall any partial  exercise of any right or remedy  hereunder  or under the
Note preclude any further  exercise  thereof or the exercise of any other right
or remedy  hereunder  or under the Note.  Such  rights and  remedies  expressly
provided are cumulative and not exclusive of any rights or remedies which CAPCO
would otherwise have.

     20.  EXPENSES.  The  Fund(s)  (to be  allocated  among  the  Funds  as the
Borrowers deem  appropriate)  shall pay on demand all reasonable  out-of-pocket
costs and expenses (including reasonable attorney's fees and expenses) incurred
by  CAPCO  in  connection  with  the  collection  and  any  other   enforcement
proceedings of or regarding this Agreement, any Loan or the Note.

     21.  BENEFIT OF  AGREEMENT.  This  Agreement and the Note shall be binding
upon  and  inure  for  the  benefit  of and be  enforceable  by the  respective
successors  and assigns of the parties  hereto;  provided that no party to this
Agreement  or the Note may  assign any of its rights  hereunder  or  thereunder
without the prior written consent of the other parties.

     22.  NOTICES.  All  notices  hereunder  and  all  written,   facsimile  or
telecopied  confirmations  of Oral Requests made hereunder shall be sent to the
Borrowers as indicated on Exhibit B and to CAPCO as indicated on Exhibit C.

     23.  MODIFICATIONS.  No  provision  of this  Agreement  or the Note may be
waived,  modified  or  discharged  except by mutual  written  agreement  of all
parties. THIS WRITTEN LOAN AGREEMENT AND THE NOTE REPRESENT THE FINAL AGREEMENT
BETWEEN  THE  PARTIES  AND  MAY  NOT BE  CONTRADICTED  BY  EVIDENCE  OF  PRIOR,
CONTEMPORANEOUS  OR SUBSEQUENT  ORAL  AGREEMENTS  OF THE PARTIES.  THERE ARE NO
UNWRITTEN AGREEMENTS BETWEEN THE PARTIES.

     24.  GOVERNING LAW AND  JURISDICTION.  This Agreement shall be governed by
and
                                       9
<PAGE>
construed in accordance  with the laws of the state of Texas without  regard to
the choice of law provisions thereof.

     25.  TRUST  DISCLAIMER.  Neither  the  shareholders,  trustees,  officers,
employees and other agents of any Borrower or Fund shall be personally bound by
or liable for any indebtedness,  liability or obligation hereunder or under the
Note nor shall resort be had to their private  property for the satisfaction of
any obligation or claim hereunder.

If this letter  correctly  reflects your agreement with us, please execute both
copies hereof and return one to us,  whereupon this Agreement  shall be binding
upon the Borrowers, the Funds and CAPCO.

Sincerely,

USAA CAPITAL CORPORATION

                          MASTER GRID PROMISSORY NOTE


U.S. $750,000,000                                       Dated: January 13, 1998


     FOR  VALUE  RECEIVED,  each  of the  undersigned  (each a  "Borrower"  and
collectively the "Borrowers"),  severally and not jointly, on behalf of and for
the benefit of the series of funds  comprising  each such Borrower as listed on
Schedule A to the  Agreement as defined  below (each a "Fund" and  collectively
the "Funds") promises to pay to the order of USAA Capital Corporation ("CAPCO")
at CAPCO's  office  located at 9800  Fredericksburg  Road,  San Antonio,  Texas
78288,  in  lawful  money of the  United  States  of  America,  in  immediately
available  funds,  the  principal  amount  of all  Loans  made by CAPCO to such
Borrower for the benefit of the applicable  Funds under the Facility  Agreement
Letter dated January 13, 1998 (as amended or modified, the "Agreement"),  among
the  Borrowers and CAPCO,  together with interest  thereon at the rate or rates
set forth in the Agreement.  All payments of interest and principal outstanding
shall be made in accordance with the terms of the Agreement.

     This Note  evidences  Loans  made  pursuant  to,  and is  entitled  to the
benefits  of,  the  Agreement.  Terms not  defined in this Note shall be as set
forth in the Agreement.

     CAPCO is  authorized  to endorse the  particulars  of each Loan  evidenced
hereby  on  the  attached  Schedule  and  to  attach  additional  Schedules  as
necessary,  provided  that the failure of CAPCO to do so or to do so accurately
shall not affect the obligations of any Borrower (or the Fund for whose benefit
it is borrowing) hereunder.

     Each  Borrower  waives all claims to  presentment,  demand,  protest,  and
notice  of  dishonor.  Each  Borrower  agrees  to pay all  reasonable  costs of
collection,  including  reasonable  attorney's  fees  in  connection  with  the
enforcement of this Note.

     CAPCO hereby agrees (i) that any claim,  liability,  or obligation arising
hereunder  or under the  Agreement  whether on account of the  principal of any
Loan,  interest thereon,  or any other amount due hereunder or thereunder shall
be satisfied only from the assets of the specific Fund for whose benefit a Loan
is  borrowed  and in any  event in an  amount  not to  exceed  the  outstanding
principal  amount of any Loan borrowed for such Fund's  benefit,  together with
accrued and unpaid interest due and owing thereon, and such Fund's share of any
other amount due hereunder and under the Agreement (as determined in accordance
with the provisions of the Agreement) and (ii) that no assets of any Fund shall
be used to satisfy any claim,  liability,  or obligation  arising  hereunder or
under the Agreement  with respect to the  outstanding  principal  amount of any
Loan  borrowed  for the  benefit  of any other Fund or any  accrued  and unpaid
interest  due and owing  thereon or such other Fund's share of any other amount

<PAGE>

due hereunder and under the  Agreement  (as  determined in accordance  with the
provisions of the Agreement).

     Neither the shareholders,  trustees,  officers, employees and other agents
of any  Borrower  or Fund  shall  be  personally  bound  by or  liable  for any
indebtedness,  liability  or  obligation  hereunder or under the Note nor shall
resort be had to their private  property for the satisfaction of any obligation
or claim hereunder.

     Loans under the  Agreement  and this Note are  subordinated  to loans made
under the  $100,000,000  364-day  committed  Mater  Revolving  Credit  Facility
Agreement between the Borrowers and NationsBank of Texas,  N.A.  (NationsBank),
dated  January  14,  1998,  in the  manner  and to the  extent set forth in the
Agreement among the Borrowers, CAPCO and NationsBank, dated January 14, 1998.

     This Note shall be governed by the laws of the state of Texas.

January 14, 1998

USAA Mutual Fund, Inc.,
USAA Investment Trust,
USAA Tax Exempt Fund, Inc., and
USAA State Tax-Free Trust, on behalf of and for the
benefit of the series
of funds comprising each such Borrower
as set forth on Schedule A hereto
9800 Fredericksburg Road
San Antonio, Texas  78288

Attention:  Michael J.C. Roth, President

Gentlemen:

This  Facility Agreement  Letter (this "Agreement")  sets forth  the  terms and
conditions  for  loans  (each  a  "Loan"  and  collectively  the "Loans") which
NationsBank  of  Texas,  N.A.  (the  "Bank")  agrees to  make during the period
commencing January 14, 1998 and ending January 13, 1999 (the "Facility Period")
to USAA Mutual Fund, Inc., USAA  Investment Trust, USAA  Tax Exempt Fund, Inc.,
and USAA State Tax-Free Trust, and  each investment company which may  become a
party hereto  pursuant to  the terms of  this Agreement (each  a "Borrower" and
collectively  the "Borrowers"),  each of which  is executing this  Agreement on
behalf  of  and for  the benefit  of the  series  of funds comprising each such
Borrower as set forth on Schedule A hereto (as hereafter modified or amended in
accordance with the terms hereof) (each a "Fund" and collectively the "Funds"),
under  a master  revolving credit  facility (the  "Facility").  This  Agreement
replaces  in its  entirety that certain Facility Agreement Letter dated January
15,  1997, as  heretofore amended  or modified,  between the  Borrowers and the
Bank.  The Bank and the Borrowers hereby agree as follows:

     1.  AMOUNT.  The  aggregate principal  amount of  the Loans to be advanced
under this  Facility shall not exceed, at any one time outstanding, One Hundred
Million  United States  Dollars  (U.S. $100,000,000)  (the  "Commitment").  The
aggregate principal amount of the Loans which may be

<PAGE>

borrowed by a Borrower for the benefit of a particular Fund under  the Facility
and the  Other Facility (hereinafter  defined) shall  not exceed the percentage
(the  "Borrowing  Limit")  of the  total assets  of such  Fund as  set forth on
Schedule A hereto.

     2.  PURPOSE  AND LIMITATIONS  ON BORROWINGS.  Each  Borrower will  use the
proceeds of each Loan made to it solely for temporary or emergency  purposes of
the  Fund for  whose benefit  it is  borrowing in  accordance with  such Fund's
Borrowing Limit and prospectus in  effect at  the time of such Loan.  Portfolio
securities  may not  be purchased  by a Fund  while there is a Loan outstanding
under  the Facility and/or  a loan outstanding under the Other Facility for the
benefit of such Fund, if the  aggregate amount of such Loan and such other loan
exceeds 5% of the total assets of such Fund.  The Borrowers  will not, and will
not  permit any  Fund to,  directly or indirectly, use any proceeds of any Loan
for any  purpose which  would violate any  provision of any applicable statute,
regulation,  order or restriction, including, without limitation, Regulation U,
Regulation T, Regulation X or any other regulation of the Board of Governors of
the  Federal Reserve System or the Securities Exchange Act of 1934, as amended.
If requested by  the Bank, the  Borrowers will promptly furnish the Bank with a
statement  in conformity  with the  requirements of Federal Reserve Form U-1 as
referred to in Regulation U.

     3.  BORROWING RATE  AND MATURITY OF  LOANS.  The principal  amount of  the
Loans outstanding  from time to  time shall bear  interest at a rate per  annum
equal to, at the option of the applicable Borrower(s), (i) the aggregate of the
Federal Funds Rate (as defined below) plus .125 of one percent (1%) (12.5 basis
points) or (ii) the aggregate of the London Interbank Offered Rate (as  defined
below)  plus  12.5  basis  points.   The  rate  of  interest  payable  on  such
outstanding amounts shall change on each date that the Federal Funds Rate shall
change.  Interest  on the  Loans shall  be calculated on the basis of a year of
360 days and  the actual days elapsed  but shall not  exceed the highest lawful
rate.  Each  Loan will be for  an established  number of days to be agreed upon
by  the  applicable  Borrower(s) and  the  Bank  and,  in  the  absence of such
agreement, will  mature on  the earlier  of three months after the date of such
Loan  or the  last day of the Facility Period.   The term "Federal Funds Rate,"
as  used herein,  shall mean  the overnight rate for Federal funds transactions
between member banks of the Federal Reserve System, as published by the Federal
Reserve Bank  of New York or, if  not so published, as determined in good faith
by the Bank in  accordance with  its customary  practices; and the term "London
Interbank Offered Rate," as used herein, shall mean the rate per 

<PAGE>

annum at  which United  States dollar  deposits are  offered by the Bank in the
London  interbank market  at approximately  11:00 a.m. London time two business
days prior to the first day of the interest period (of 7 or 14 days or one, two
or three months as selected by the Borrower(s)) for which  the London Interbank
Offered Rate  is to be  in effect, as adjusted by the Bank in good faith and in
accordance  with its  customary practices  for any reserve costs imposed on the
Bank  under Federal  Reserve Board Regulation  D with respect to "Euro-currency
Liabilities".  The  London  Interbank  Offered  Rate  shall  not  be  available
hereunder if it would be unlawful  for the Bank to make or maintain Loans based
on such rate or if such rate  does not, in the good faith judgment of the Bank,
fairly reflect the cost to the Bank of making or maintaining Loans.  The London
Interbank Offered Rate shall not be available for any interest period which, if
such  rate  were available,  would begin  after the  occurrence and  during the
continuation of an Event of Default (as defined below).  Any past due principal
and/or  accrued interest  shall bear  interest at a rate per annum equal to the
aggregate of the Federal Funds Rate plus 1.125 percent (112.5 basis points) and
shall be  payable on  demand.  If the applicable Borrowers do not affirmatively
elect  to have  a Loan or  Loans bear  interest based  on the  London Interbank
Offered Rate  at least  two business  days prior to the first day of a possible
interest  period applicable  thereto, such  Loan or  Loans shall  bear interest
based on the Federal Funds Rate until such election is affirmatively made.

     4.  ADVANCES,  PAYMENTS, PREPAYMENTS AND READVANCES.  Upon each Borrower's
request, and  subject to  the terms  and conditions  contained herein, the Bank
shall  make Loans  to each  Borrower on  behalf of  and for  the benefit of its
respective  Fund(s) during  the Facility  Period, and each Borrower may borrow,
repay  and reborrow  funds hereunder.  The  Loans shall  be evidenced by a duly
executed  and delivered  Master Grid Promissory  Note in the form of EXHIBIT A.
Each  Loan shall be  in an aggregate  amount not less than One Hundred Thousand
United States  Dollars (U.S. $100,000)  and increments  of One Thousand  United
States  Dollars (U.S. $1,000)  in excess  thereof.  Payment  of  principal  and
interest due with respect to each Loan shall be payable at the maturity of such
Loan  and shall  be made in  funds immediately available to the Bank prior to 2
p.m. Dallas time on the day such payment is due, or as the Bank shall otherwise
direct  from time to time and, subject  to the terms and conditions hereof, may
be repaid with the proceeds of a new borrowing hereunder.  Notwithstanding  any
provision  of this  Agreement to  the contrary,  all Loans,  accrued but unpaid
interest  and other  amounts payable  hereunder shall  be due  and payable upon
termination of the Facility (whether by  

<PAGE>

acceleration or  otherwise).   If any Loan bearing interest based on the London
Interbank Offered  Rate is repaid or prepaid  other than on the last  day of an
interest  period applicable thereto,  the Fund which is the beneficiary of such
Loan  shall pay  to the  Bank promptly  upon demand  such amount  as  the  Bank
determines in good faith is necessary to compensate the Bank for any reasonable
cost  or  expense  incurred  by  the  Bank  as  a  result  of such repayment or
prepayment  in connection with  the reemployment of funds in an amount equal to
such  repayment or  prepayment.  Whenever the Bank seeks to assess for any such
cost or  expense it  will  provide  a  certificate  as  the  Borrower(s)  shall
reasonably request.

     5.  FACILITY  FEE.  Beginning  with the  date of  this Agreement and until
such time as  all Loans have  been irrevocably repaid  to the Bank in full, and
the Bank  is no longer  obligated  to  make Loans,  the  Funds (to be allocated
among  the Funds  as the  Borrowers  deem appropriate) shall  pay to the Bank a
facility  fee (the "Facility Fee") in the amount of .05 of one percent (5 basis
points) of  the amount of  the Commitment, as it  may be  reduced  pursuant  to
section  6.  The  Facility Fee  shall be payable quarterly in arrears beginning
March 31, 1998, and upon  termination of  the Facility (whether by acceleration
or otherwise).

     6.  OPTIONAL TERMINATION OR REDUCTION  OF COMMITMENT.  The Borrowers shall
have  the right  upon at least  three (3) business days prior written notice to
the Bank, to  terminate or reduce  the unused portion  of the  Commitment.  Any
such reduction of the  Commitment shall be in the amount of Five Million United
States Dollars (U.S. $5,000,000) or any larger integral multiple of One Million
United  States Dollars  (U.S. $1,000,000)  (except that any reduction may be in
the  aggregate amount  of the unused Commitment).  Accrued fees with respect to
the terminated Commitment shall be payable to the Bank on the effective date of
such termination.

     7.  MANDATORY   TERMINATION   OF   COMMITMENT.    The   Commitment   shall
automatically  terminate on  the last  day of the Facility Period and any Loans
then  outstanding (together with accrued interest thereon and any other amounts
owing hereunder) shall be due and payable on such date.

     8.  COMMITTED  FACILITY.  The  Bank  acknowledges  that the  Facility is a
committed  facility  and that  the Bank  shall be  obligated  to make  any Loan
requested during the Facility Period under this Agreement, subject to the

<PAGE>

terms  and conditions  hereof;  provided, however,  that the  Bank shall not be
obligated  to make  any Loan  if this  Facility  has  been  terminated  by  the
Borrowers,  or if  at the time of a request for a Loan by a Borrower (on behalf
of  the  applicable  Fund(s))  there  exists any  Event of Default or condition
which, with the passage of time or giving of notice, or both, would  constitute
or become an Event of Default with respect to such Borrower (or such applicable
Fund(s)).

     9.  LOAN REQUESTS.  Each  request for  a Loan (each a "Borrowing  Notice")
shall be in writing by the applicable Borrower(s), except that such Borrower(s)
may make  an oral request  (each an "Oral  Request") provided  that  each  Oral
Request  shall be  followed by  a written  Borrowing Notice within one business
day.  Each Borrowing Notice  shall specify the following terms ("Terms") of the
requested Loan:  (i) the date on  which such Loan  is to be disbursed, (ii) the
principal  amount of such  Loan, (iii) the Borrower(s) which are borrowing such
Loan  and the amount  of such  Loan to be  borrowed by  each Borrower, (iv) the
Funds for  whose benefit  the Loan is being borrowed and the amount of the Loan
which  is for the  benefit of each  such Fund, (v) whether such Loan shall bear
interest at  the Federal Funds  Rate or the  London Interbank Offered Rate, and
(vi) the requested maturity date of the Loan.  Each Borrowing Notice shall also
set forth the total assets of each Fund for whose benefit a portion of the Loan
is being borrowed as of the close of business on the day immediately  preceding
the date of such Borrowing Notice.  Borrowing Notices shall be delivered to the
Bank by 1:00 p.m. Dallas  time on the  day the Loan is  requested to be made if
such Loan is to bear interest based on the Federal Funds Rate or  by 10:00 a.m.
Dallas time on the second business day before  the Loan is requested to be made
if such Loan is to bear interest based on the London Interbank Offered Rate.

Each  Borrowing Notice  shall constitute  a representation  to the  Bank by the
applicable  Borrower(s) that  all of  the  representations  and  warranties  in
Section 12  hereof are  true and  correct as  of such date and that no Event of
Default or other condition which with  the passage of time or giving of notice,
or both, would result in an Event of Default, has occurred or is occurring.

     10.  CONFIRMATIONS;  CREDITING  OF  FUNDS;  RELIANCE  BY  THE  BANK.  Upon
receipt by the Bank of a Borrowing Notice:

          (a)  The   Bank   shall   send   each   applicable  Borrower  written
confirmation  of the  Terms of  such  Loan  via facsimile or  telecopy, as soon

<PAGE>

as reasonably  practicable; provided,  however, that the failure to do so shall
not affect the obligation of any such Borrower;

          (b)  The Bank  shall make  such Loan  in accordance with the Terms by
transfer of  the Loan  amount in immediately available funds, to the account of
the  applicable Borrower(s)  as specified  in EXHIBIT B to this Agreement or as
such Borrower(s)  shall otherwise specify to the Bank in a writing signed by an
Authorized  Individual (as defined  in Section 11) of such Borrower(s) and sent
to the Bank via facsimile or telecopy; and

          (c)  The  Bank shall  make appropriate  entries on  the Note  or  the
records  of the Bank  to reflect the Terms of the Loan; provided, however, that
the failure to do so shall not affect the obligation of any Borrower.

The Bank shall  be entitled to rely upon and act hereunder pursuant to any Oral
Request  which it  reasonably believes  to have  been made  by  the  applicable
Borrower through  an Authorized  Individual.  If any Borrower believes that the
confirmation  relating to  any Loan  contains any error or discrepancy from the
applicable Oral Request, such Borrower will promptly notify the Bank thereof.

     11.  BORROWING  RESOLUTIONS  AND  OFFICERS'  CERTIFICATES;   Subordination
Agreement.  Prior  to the making  of any Loan  pursuant to  this Agreement, the
Borrowers shall  have delivered  to the Bank  (a) the duly  executed Note,  (b)
resolutions of each Borrower's Trustees or  Board of Directors authorizing such
Borrower  to execute, deliver and perform this Agreement and the Note on behalf
of the applicable Funds, (c) an Officer's Certificate in substantially the form
set forth  in EXHIBIT  D to  this  Agreement, authorizing  certain  individuals
("Authorized  Individuals"), to take  on behalf of  each Borrower (on behalf of
the applicable  Funds) actions contemplated by this Agreement and the Note, (d)
a subordination agreement in substantially the  form set forth  in EXHIBIT E to
this  Agreement, and  (e) the  opinion of counsel to USAA Investment Management

     12.  REPRESENTATIONS AND WARRANTIES.  In order to induce the Bank to enter
into this Agreement and to make the Loans provided for hereunder, each Borrower
hereby makes  with respect to  itself, and as  may be relevant,  the series  of
Funds comprising such Borrower the following representations and 

<PAGE>

warranties,  which shall survive  the execution and delivery  hereof and of the
Note:

borrow under the Note and to carry out the terms hereof and thereof;

          (b)  FINANCIAL  INFORMATION;  DISCLOSURE,  ETC.   The  Borrower   has

principles  applied  on a  consistent basis  and fairly  present  the financial
position and results of operations of such Borrower and the applicable Funds on
the  dates  and  for  the  periods  indicated.  Neither  this Agreement nor any
financial statements,  reports or other documents  or certificates furnished to
the  Bank  by  such  Borrower  or  the  applicable Funds in connection with the
transactions  contemplated hereby  contain any  untrue statement  of a material
fact  or omit  to state  any material  fact necessary  to make  the  statements
contained  herein or  therein in  light of  the  circumstances  when  made  not
misleading;

          (c)  AUTHORIZATION;   COMPLIANCE   WITH    OTHER  INSTRUMENTS.    The
execution,  delivery  and  performance  of  this  Agreement  and  the Note, and
borrowings hereunder, have  been duly authorized  by all necessary corporate or
trust action of  the Borrower and  will not result in any violation of or be in
conflict with or constitute a default under any term of the charter, by-laws or
trust agreement of  such Borrower or the applicable Funds,  or of any borrowing
restrictions  or prospectus  or statement  of additional  information  of  such
Borrower or  the applicable  Funds, or  of any agreement, instrument, judgment,
decree,  order, statute,  rule or governmental  regulation applicable  to  such
Borrower,  or  result  in  the  creation  of  any  mortgage,  lien,  charge  or
encumbrance  upon any  of the  properties  or assets   of such Borrower  or the
applicable  Funds pursuant  to any such  term.  The Borrower and the applicable
Funds are not in violation of any  term of their respective charter, by-laws or
trust  

<PAGE>

          (d)  SEC COMPLIANCE.  The  Borrower and  the applicable  Funds are in
compliance  in all material  respects with  all federal and state securities or
similar  laws and  regulations, including  all material rules,  regulations and

          (e)  LITIGATION.  There is no action, suit or proceeding  pending or,
to the  best of the Borrower's  knowledge, threatened against  such Borrower or
the applicable Funds in any court or before any arbitrator or governmental body
which seeks to restrain any of the transactions  contemplated by this Agreement
or which, if adversely  determined, could have a material adverse effect on the
assets or  business operations of such Borrower  or the applicable Funds or the
ability  of such Borrower  and the applicable  Funds to pay  and perform  their
obligations hereunder and under the Notes; and

          (f)  BORROWERS' RELATIONSHIP  TO FUNDS.  The assets of  each Fund for
whose  benefit Loans are borrowed by the applicable Borrower are subject to and
liable for  such Loans and  are available  to the applicable  Borrower for  the
repayment of such Loans.

     13.  AFFIRMATIVE  COVENANTS OF  THE BORROWERS.   Until such  time  as  all
amounts of principal and interest due to the Bank by a Borrower pursuant to any
Loan made to such Borrower  is irrevocably  paid in full, and until the Bank is
no longer obligated  to make Loans to such Borrower,  such Borrower (for itself
and on behalf of its respective Funds) agrees:

its Borrowing Limit at the end of such semiannual period;

          (c)  To  deliver to  the Bank  prompt notice of the occurrence of any
event or  condition which  constitutes, or  is likely to result in, a change in
such  Borrower or  any applicable  Fund which  could reasonably  be expected to

repay outstanding Loans made for its benefit or the ability of such Borrower to
perform its obligations under this Agreement or the Note;

          (d)  To do, or cause to be done, all things necessary to preserve and
keep in full force and effect the corporate or trust existence of such Borrower

and

          (g)  Upon  the  request  of the Bank, which may  be made by  the Bank

been a material  adverse change in the capital markets generally, to deliver to
the Bank,  within two business days  after  such request,  a statement  setting
forth the total assets of each Fund for whose  benefit a Loan is outstanding on
the date of such request.

     14.  NEGATIVE COVENANTS  OF THE BORROWERS.  Until such time as all amounts
of principal  and interest due  to the Bank by a Borrower  pursuant to any Loan
made to such Borrower is  irrevocably paid in full,  and until the  Bank is  no
longer obligated to make Loans to such Borrower,  such Borrower (for itself and
on behalf of its respective Funds) agrees:

          (a)  Not  to incur  any indebtedness  for borrowed money  (other than
pursuant  to a $750,000,000  uncommitted master revolving  credit facility with
USAA Capital Corporation (the "Other  Facility") and overdrafts incurred at the
custodian  of the Funds  from time to time  in the ordinary course of business)
except the Loans, without the prio r written consent of the Bank, which consent
will not be unreasonably withheld; and

          (b)  Not  to  dissolve  or  terminate  its  existence,  or  merge  or 
consolidate with any  other person or  entity, or sell all or substantially all
of its assets in a single transaction or series  of related transactions (other
than assets consisting of margin stock), each without the prior written consent 
of the Bank,  which consent will not be  unreasonably withheld; provided that a
Borrower  may  without  such  consent  merge,  consolidate  with,  or  purchase
substantially all of the assets of, or sell substantially all of its assets to,
an  affiliated investment  company or series  thereof, as provided  for in Rule
17a-8 of the Investment Company Act of 1940.

     15.  EVENTS OF DEFAULT.  If any of the following events (each an "Event of
Default") shall  occur (it being  understood  that  an Event  of  Default  with
respect  to one Fund  or Borrower shall not constitute an Event of Default with
respect to any other Fund or Borrower):

<PAGE>

          (a)  Any Borrower  or Fund shall default in  the payment of principal
or interest on any Loan or any other fee due hereunder for a period of five (5)
days  after the  same becomes  due and  payable, whether  at maturity  or  with
respect to the Facility Fee at a date fixed for the payment thereof;

          (b)  Any  Borrower or Fund  shall default  in the  performance  of or
compliance  with any term contained in Section 13 hereof and such default shall
not  have been remedied  within thirty (30)  days after written  notice thereof
shall have been given such Borrower or Fund by the Bank;

          (c)  Any  Borrower or  Fund shall  default in  the performance  of or
compliance with any term contained in Section 14 hereof;

          (d)  Any  Borrower or  Fund  shall  default  in  the  performance  or
compliance with any other term contained herein and such default shall not have

          (e)  Any representation or warranty made by a Borrower or Fund herein
or  pursuant hereto shall prove to have been false or incorrect in any material
respect when made;

          (f)  USAA  Investment Management  Company or any successor manager or
investment  adviser, provided that such  successor is a wholly-owned subsidiary
of  USAA Capital  Corporation, shall  cease to  be the  Manager and  investment
advisor of each Fund; or

          (g)  An  event of  default shall  occur and  be continuing  under the
Other Facility;

then, in any event,  and at any time thereafter,  if any Event of Default shall
be  continuing,  the Bank may  by written notice  to the applicable Borrower or
Fund (i) terminate  its commitment to make  any Loan hereunder,  whereupon said
commitment shall forthwith terminate without any  other notice of any kind with
respect to such Borrower or Fund and (ii) declare the principal and interest in
respect of any outstanding Loans with respect to such Borrower or Fund, and all
other  amounts due  hereunder with  respect to  such Borrower  or Fund,  to  be
immediately  due and  payable whereupon  the principal  and interest in respect
thereof and all other amounts due hereunder shall become  

<PAGE>

forthwith due and payable without presentment, demand, protest  or other notice
of any kind, all of which are expressly waived by the Borrowers.

     16.  NEW  BORROWERS;  NEW FUNDS.  So  long  as  no  Event  of  Default  or
condition  which, with  the passage of  time or the  giving of notice, or both,
would constitute or  become an Event of Default has occurred and is continuing,
and with the prior consent  of the Bank, which consent will not be unreasonably
withheld:

          (a)  Any investment  company that becomes  part of the same "group of
investment  companies" (as  that term  is  defined  in  Rule  11a-3  under  the
Investment Company  Act of 1940)  as the original  Borrowers to this Agreement,
may, by submitting an amended Schedule A and Exhibit B to this Agreement to the
Bank (which amended  Schedule A and Exhibit B  shall replace the Schedule A and
Exhibit B which are then a part of this  Agreement) and such other documents as
the  Bank may  reasonably request,  become a  party to  this Agreement  and may
become a "Borrower" hereunder; and

          (b)  A Borrower may, by submitting an  amended Schedule A and Exhibit
B to this Agreement  to the Bank (which amended  Schedule A and Exhibit B shall
replace the  Schedule A and Exhibit B which are then a part of this Agreement),
add additional Funds for whose benefit such Borrower may borrow Loans.  No such
amendment  of Schedule  A to this  Agreement shall  amend the  Borrowing  Limit
applicable to any Fund without the prior consent of the Bank.

     17.  LIMITED RECOURSE.  The Bank agrees  (i) that any claim, liability, or
obligation  arising hereunder  or under  the Note  whether on  account  of  the
principal of  any Loan,  interest thereon, or any other amount due hereunder or
thereunder  shall be  satisfied only  from the assets  of the specific Fund for
whose  benefit a Loan is borrowed  and in any event in  an amount not to exceed
the outstanding principal amount of any Loan  borrowed for such Fund's benefit,
together  with accrued  and unpaid  interest due  and owing thereon,  and  such
Fund's  share of  any  other  amount  due  hereunder and  under  the  Note  (as
determined in accordance with the provisions hereof) and (ii) that no assets of
any  Fund shall  be used to satisfy any claim, liability, or obligation arising
hereunder  or under  the Note  with respect to the outstanding principal amount
of  any Loan  borrowed for  the benefit  of any  other Fund  or any accrued and
unpaid interest due  and owing thereon or such other  Fund's share of any other

<PAGE>

amount due hereunder and under  the Note (as determined in  accordance with the
provisions hereof).

     18.  REMEDIES ON DEFAULT.  In case any one or more Events of Default shall
occur and be continuing, the Bank may proceed to protect and enforce its rights
by an  action at law,  suit in equity or other appropriate proceedings, against
the applicable Borrower(s)  and/or Fund(s), as the case may be.  In the case of
a default in  the payment of  any principal or interest  on any Loan or  in the
payment  of any fee due  hereunder, the relevant Fund(s) (to be allocated among
such Funds  as the  Borrowers deem  appropriate) shall  pay to  the  Bank  such
further  amount as  shall be  sufficient to  cover  the  cost  and  expense  of
collection,  including,  without  limitation,  reasonable  attorney's  fees and 
expenses.

     19.  NO WAIVER OF  REMEDIES.  No course of  dealing or failure or delay on
the  part of the Bank  in exercising any right or remedy hereunder or under the
Note shall  constitute a waiver  of any right or  remedy hereunder or under the
Note, nor  shall any partial exercise of any right or remedy hereunder or under
the Note preclude any further  exercise thereof or  the exercise  of any  other
right  or remedy  hereunder or  under  the  Note.   Such  rights  and  remedies
expressly  provided  are cumulative and not exclusive of any rights or remedies
which the Bank would otherwise have.

     20.  EXPENSES.   The Fund(s) (to  be  allocated among  the  Funds  as  the
Borrowers  deem appropriate)  shall pay on  demand all reasonable out-of-pocket 
costs and expenses (including reasonable attorney's fees and expenses) incurred
by  the Bank  in connection  with the  collection  and  any  other  enforcement
proceedings of or regarding this Agreement, any Loan or the Note.

     21.  BENEFIT  OF AGREEMENT.  This Agreement  and the Note shall be binding
upon  and inure  for the benefit  of  and  be  enforceable  by  the  respective
successors  and assigns  of the parties  hereto; provided that no party to this
Agreement or the  Note may assign  any of its  rights hereunder  or  thereunder
without the prior written consent of the  other parties.  The Bank may not sell
participations  and  subparticipations  in all  or any part  of the  Loans made
hereunder without  the prior consent of the Borrowers,  which consent shall not
be unreasonably withheld.

     22.  NOTICES.   All notices  hereunder  and  all  written,  facsimiled  or
telecopied  confirmations of  Oral Requests made hereunder shall be sent to the

<PAGE>

Borrowers as indicated on EXHIBIT B and  to the Bank as indicated on EXHIBIT C.
Written  communications shall  be deemed to  have been  duly given  and made as
follows:   If sent by  mail, seventy-two  (72) hours  after deposit in the mail
with  first-class  postage prepaid,  addressed as  provided in  EXHIBIT  B (the
Borrowers) and EXHIBIT C (the Bank); and in  the case of facsimile or telecopy,
when the facsimile or telecopy is received if on a business day or otherwise on
the next business day.

     23.  MODIFICATIONS.   No provision  of this Agreement  or the  Note may be
waived,  modified or  discharged except  by mutual  written  agreement  of  all
parties.   THIS  WRITTEN  LOAN  AGREEMENT  AND  THE  NOTE  REPRESENT  THE FINAL
AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS  OR  SUBSEQUENT  ORAL  AGREEMENTS OF THE PARTIES.  THERE ARE NO
UNWRITTEN AGREEMENTS BETWEEN THE PARTIES.

     24.  INCREASED  COST AND  REDUCED RETURN.  If at  any time after  the date
hereof, the  Bank (which  shall include,  for purposes  of  this  Section,  any
corporation controlling the Bank)  determines that the adoption or modification
of any  applicable law  regarding the Bank's required levels of reserves, other
than  the reserve  requirement taken  into account  when computing  the  London
Interbank  Offered Rate  as provided  in Section 3,  or capital  (including any
allocation of  capital requirements or conditions), or similar requirements, or
any  interpretation  or  administration  thereof  by  a  governmental  body  or
compliance  by the  Bank with  any of such  requirements, has or would have the
effect  of (a)  increasing the  Bank's costs  relating to  the  Loans,  or  (b)
reducing the yield or rate of return of the Bank on the Loans, to a level below
that which the Bank could have achieved but for the adoption or modification of
any  such requirements,  the Funds  (to be  allocated among  the Funds  as  the
Borrowers  deem appropriate)  shall, within fifteen (15) days of any request by
the Bank,  pay to  the Bank  such additional  amounts as  (in the  Bank's  sole
judgment, after good faith and reasonable computation) will compensate the Bank
for such increase in costs or reduction in yield or rate of return of the Bank.
Whenever  the Bank  shall seek  compensation  for  any  increase  in  costs  or
reduction  in yield  or rate of return, the Bank shall provide a certificate as
the  Borrower(s) shall  reasonably request.   Failure  by  the Bank  to  demand
payment  within 90  days of  any additional  amounts  payable  hereunder  shall
constitute  a waiver of  the Bank's right  to demand payment of such amounts at
any subsequent time.  Nothing herein contained shall be construed or so operate
as to require the

<PAGE>

Borrowers or the Funds to pay any interest, fees, costs or charges greater than
is permitted by applicable law.

the benefit of  the series  of funds comprising each such Borrower as listed on
Schedule A  to the  Agreement as  defined below (each a "Fund" and collectively

     The Bank is  authorized to endorse the particulars  of each Loan evidenced
hereby  on  the  attached  Schedule  and  to  attach  additional  Schedules  as

     Each  Borrower  waives  all  claims  to  presentment, demand, protest, and
notice  of  dishonor.   Each  Borrower  agrees to  pay all  reasonable costs of

any  Loan, interest  thereon, or any other  amount due hereunder  or thereunder
shall be satisfied only from  the assets of the specific Fund for whose benefit
a Loan is borrowed and in any event in an amount not to exceed the  outstanding
principal  amount of any  Loan borrowed  for such Fund's benefit, together with
accrued and unpaid interest due and owing thereon, and such Fund's share of any
other amount due hereunder and under the Agreement (as determined in accordance
with the provisions of the Agreement) and (ii) that no assets of any Fund shall
be  used to  satisfy any  claim, liability,  or obligation arising hereunder or
under the  Agreement with respect  to the  outstanding principal  amount of any
Loan  borrowed for  the benefit  of any  other Fund  or any  accrued and unpaid
interest  due and owing  thereon or such other Fund's share of any other amount
due  hereunder  and under the  Agreement  (as determined in accordance with the
provisions of the Agreement).

resort be had to their private property for the satisfaction  of any obligation
or claim hereunder.

NationsBank of Texas, N.A.             Agreement

This is an agreement among:                            Dated:  January 14, 1998

Name and Address of Lender (Including County):

NationsBank of Texas, N.A.
901 Main Street
Dallas, Dallas County, Texas  75202

  (Lender)

Name and Address of Borrower:

USAA Mutual Fund, Inc.
USAA Investment Trust
USAA Tax Exempt Fund, Inc.
USAA State Tax-Free Trust
9800 Fredericksburg Road
San Antonio, Texas   78288

  (Debtor)

Name and Address of Creditor:

USAA Capital Corporation
9800 Fredericksburg Road
San Antonio, Texas  78288

  (Creditor)

1.  Background.   Debtor is or  may be  indebted to  Lender  pursuant  to  that
    certain Facility Agreement Letter dated January 14, 1998 between Debtor and
    Lender ("Senior Facility Agreement").  Debtor also is or may be indebted to
    Creditor  pursuant to  that certain Facility Agreement Letter dated January
    13, 1998  between Debtor  and Creditor ("Subordinated Facility Agreement").
    All debt  (as hereinafter defined)  under th e Senior Facility Agreement is
    hereinafter  referred to  as "senior  debt"  and all  debt  (as hereinafter
    defined)  under the Subordinated Facility Agreement is hereinafter referred
    to as "subordinated debt".

2.  Definition of Debt.  The term "debt" as used in the terms "senior debt" and
    "subordinated debt"  means all debts,  obligations and liabilities,  now or
    hereafter  existing, direct  or indirect,  absolute or contingent, joint or
    several, secured  or unsecured,  due or not due,  contractual  or tortious,
    liquidated  or unliquidated,  arising by  operation  of law  or  otherwise,
    irrespective  of the  person in  whose favor  such debt may originally have
    been created  and regardless  of the manner  in which such debt has been or
    may  hereafter be  acquired by  Lender or Creditor, as the case may be, and
    includes  all costs incurred  to obtain,  preserve,  perfect or enforce any
    security interest, lien or mortgage, or to collect any debt or to maintain,
    preserve, collect and enforce any collateral, and interest on such amounts.

3.  Subordination  of Debt.   Until senior  debt has been paid  in full, Debtor
    will  not pay and Creditor will not accept any payment on subordinated debt
    at  any time  that an  Event of Default  (as defined in the Senior Facility
    Agreement)  has occurred  and is  continuing in  respect  of  senior  debt.
    Anything  of value  received by Creditor on account of subordinated debt in
    violation  of this  agreement  will  be  held  by  Creditor  in  trust  and
    immediately  will be  turned over  to Lender  in the  form received  to  be
    applied by Lender on senior debt.

4.  Remedies of Creditor.  Until all senior debt has been paid in full, without
    Lender's  permission,  Creditor will  not be  a  party  to  any  action  or
    proceeding  against any person  to recover subordinated debt.  Upon written
    request of Lender,  Creditor will  file any claim or proof of claim or take
    any  other  action  to  collect   subordinated   debt  in  any  bankruptcy,
    receivership, liquidation, reorganization or other proceeding for relief of
    debtors  or in  connection with  Debtor's insolvency,  or in liquidation or
    marshaling of Debtor's assets or liabilities, or in any probate proceeding,
    and if any distribution  shall be made to Creditor,  Creditor will hold the
    same in  trust for Lender  and immediately  pay  to  Lender,  in  the  form
    received  to be  applied on senior debt, all money or other assets received
    in any  such proceedings  on account of subordinated debt until senior debt
    shall  have been paid  in full.   If Creditor shall  fail to take  any such
    action  when requested by Lender,  Lender may enforce  this agreement or as
    attorney in  fact for Creditor  and Debtor may  take  any  such  action  on
    Creditor's behalf.  Creditor hereby  irrevocably appoints Lender Creditor's
    attorney in fact to take any such action that Lender might request Creditor
    to take hereunder, and to sue for, compromise, collect and receive all such
    money and other assets and take any other action in Lender's own name or in
    Creditor's  name that  Lender shall  consider advisable for enforcement and
    collection  of subordinated debt,  and to apply  any  amounts  received  on
    senior debt.

5.  Modifications.   At any  time and  from time  to time,  without  Creditor's
    consent or notice to Creditor and without liability to Creditor and without
    releasing  or impairing  any of Lender's rights  against Creditor or any of
    Creditor's obligations  hereunder,  Lender may  take  additional  or  other
    security  for senior  debt;  release,  exchange,  subordinated or  lose any
    security  for senior debt;  release any person  obligated  on senior  debt,
    modify,  amend or  waive compliance  with any  agreement relating to senior
    debt;  grant any  adjustment,  indulgence or  forbearance to, or compromise
    with,  any person  liable for  senior debt;  neglect, delay,  omit, fail or
    refuse to take or prosecute any action for collection of any senior debt or
    to  foreclose upon  any collateral  or take  or prosecute any action on any
    agreement securing any senior debt.

6.  Subordination of Liens.   Creditor subordinates  and makes inferior  to any
    security interests,  liens or mortgages  now or hereafter  securing  senior
    debt  all security interests, liens, or mortgages now or hereafter securing
    subordinated debt.   Any foreclosure  against any property  securing senior
    debt shall foreclose,  extinguish and  discharge  all  security  interests,
    liens and  mortgages securing  subordinated debt,  and any purchaser at any
    such foreclosure sale  shall take title to the property so sold free of all
    security interest, liens and mortgages securing subordinated debt.

7.  Statement of Subordination; Assignment by Creditor; Additional Instruments.
    Debtor  and Creditor  will cause  any  instrument  evidencing  or  securing
    subordinated debt to bear upon its face a statement that such instrument is
    subordinated  to senior debt  as set forth herein and will take all actions
    and  execute  all  documents  appropriate  to  carry  out  this  agreement.
    Creditor will notify  Lender not less than 10 days before any assignment of
    any subordinated debt.

8.  Assignment by Lender.  Lender's rights under this agreement may be assigned
    in connection with any assignment or transfer of any senior debt.

9.  Venue.  Debtor and Creditor agree that this agreement is performable in the
    county of Lender's address set out above.

10. Cumulative Rights; Waivers.   This  instrument is  cumulative o f all other
    rights  and securities  of the  Lender.   No waiver by  Lender of any right
    hereunder, with respect to a particular payment, shall affect or impair its
    rights in any matters thereafter occurring.

11. Successors and Assigns.  This instrument is binding upon and shall inure to
    the benefit of the heirs, executors, administrators, successors and assigns
    of each of  the parties hereto,  but Creditor  covenants  that it  will not
    assign  subordinated debt,  or any  part thereof, without making the rights
    and interests of the assignee subject  in all respects to the terms of this
    instrument.

12. Termination.   This agreement  shall terminate  upon the termination of the
    Senior Facility Agreement and repayment in full of the senior debt.
