THis prospectus  provides you with information you should know before you invest
in the fund. Please read it and keep it for future reference.

WHO MANAGES THE FUND?

   
     USAA  Investment  Management  Company manages the Fund. For easier reading,
     USAA Investment  Management  Company will be referred to as "we" throughout
     the Prospectus.
    

WHAT IS THE INVESTMENT OBJECTIVE?

   
     The Fund's investment objective is long-term capital appreciation. See FUND
     INVESTMENTS on page 4 for more information.
    

WILL THE VALUE OF YOUR INVESTMENT FLUCTUATE?

   
     Yes, it will. The value of your investment  will increase or decrease.  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.
    

IS THIS FUND FOR YOU?

     This fund might be appropriate as part of your investment portfolio if. . .

     X  You are looking for significant growth. 
     X  You are willing to accept very high risk. 
     X  You are looking for a long-term investment.

     This  fund may NOT  be appropriate  as part  of your  investment  portfolio
     if . . .

     X  You need a steady income.
     X  You are unwilling to take a greater risk for long-term goals.
     X  You may need your money back within seven years.  
     X  You need an investment that provides tax-free income.

     If you  feel  this  fund is not the one  for  you,  refer  to page 15 for a
     complete list of the USAA Family of No-Load Mutual Funds.

     certain instances,  by telephone.  The minimum initial investment is $3,000
     [$500 for Uniform  Gifts/Transfers  to Minors Act (UGMA/UTMA)  accounts and
     $250  for  IRAs]  and  can be made  by  check  or by  wire.  There  is more

FEES AND EXPENSES

   
     This  summary  provides  information  to assist  you in  understanding  the
     expenses you will pay directly or indirectly to invest in the Fund.

     Shareholder Transaction Expenses -- Fees You Pay Directly

     There are no fees charged to your account when you buy,  sell, or hold Fund
     shares.  However,  if you  sell  shares  and  request  your  money  by wire
     transfer,  you  will pay a $10 fee.  (Your  bank may also  charge a fee for
     receiving wires.)

     Annual Fund Operating Expenses -- Fees You Pay Indirectly

     Unlike shareholder transaction charges, the Fund's expenses are not charged
     directly to your account, but instead are paid out of the Fund's assets and
     are  reflected in the Fund's share price and  dividends.  "Other  Expenses"
     such as  custodian  and  transfer  agent fees have been  estimated  for the
     Fund's  first year of  operation.  The figures  below are  calculated  as a
     percentage of average net assets.

        Management Fees                         .75%
        12b-1 Fees                              None
        Other Expenses (estimated)              .72%
                                                ---
        Total Fund Operating Expenses          1.47%
                                               ====
    

   * 12B-1 FEES -- SOME  MUTUAL  FUNDS  CHARGE  THESE  FEES TO PAY FOR THE COSTS
                   OF SELLING FUND SHARES.

     Example of Effect of Fund Operating Expenses

     You would pay the  following  expenses on a $1,000  investment in the Fund,
     assuming (1) 5% annual return and (2)  redemption at the end of the periods
     shown.

             1 year.....................     $ 15
             3 years....................       47

     THIS EXAMPLE IS NOT A REPRESENTATION  OF PAST OR FUTURE EXPENSES AND ACTUAL
     EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

Please  consider  performance  information  in  light of the  Fund's  investment
objective and policies and market  conditions  during the reported time periods.
Remember, historical performance may not be repeated in the future. The value of
your shares may go up or down. For the most current price and return information

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 dividends
and  distributions of capital gains. 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.
    

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 are  accompanied  by a higher risk of losing  money.  The
     reverse is also generally true: the lower the potential  reward,  the lower
     the risk.  However,  as you consider an investment in the Fund,  you should
     also take into account your  tolerance  for the daily  fluctuations  of the
     stock  market  and  whether  you can  afford  to leave  your  money in this
     investment for long periods of time to ride out down periods.

[CAUTION LIGHT]

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

FUND INVESTMENTS

   Investment Policies and Risks

      Q     What is the Fund's investment policy?

   
      A     Under normal  conditions,  we will invest at least 80% of the Fund's
            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."

<PAGE>

            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 we invest the Fund's assets?

      A     We will invest at least 80% of the Fund's 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]

    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]

    MARKET RISK. Because this Fund invests in equity  securities,  it is subject
    to market  risk.  Stock  prices in general  may  decline  over short or even
    extended  periods,  regardless  of the  success  or  failure  of  individual
    companies' operations. The stock market tends to run in cycles, with periods
    when stock prices generally go up and periods when stock prices generally go
    down. Equity securities tend to go up and down more than bonds.

[CAUTION LIGHT]

    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.

     We will not generally  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 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.

     For additional  information  about other investments in which we may invest
     the Fund's assets, see Appendix A on page 14.
    

                                                                               5

     Investment Restrictions

     The following restrictions may only be changed with shareholder approval:

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

     *   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.

     *   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 (SAI).

     Company has retained us, USAA Investment  Management  Company,  to serve as
     the manager and distributor of the Company.

     We are an affiliate of United Services  Automobile  Association  (USAA),  a
     large,  diversified financial services institution.  As of the date of this
     Prospectus,  we  had  approximately  $35  billion  in  total  assets  under
     management. Our mailing address is 9800 Fredericksburg Rd., San Antonio, TX
     78288.

     We provide management services to the Fund. We are responsible for managing
     the Fund's  portfolio  (including  placement of  brokerage  orders) and its

     three-fourths of one percent (.75%) of average net assets, is accrued daily
     and paid monthly.

     In addition to the fees paid pursuant to the Advisory Agreement, the Fund's
     operating  expenses generally consist of expenses for issuing and redeeming
     Fund  shares,  transfer  agent and  custodian  charges,  auditing and legal
     expenses,  certain expenses of registering and qualifying  shares for sale,
     fees of Directors who are not affiliated with us, and costs of typesetting,
     printing, and mailing the Prospectus, SAI, and periodic reports to existing
     shareholders.
    

     We  also  provide  distribution   services  to  the  Fund  and  receive  no
     compensation for those services.

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

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.

                                                                               7

<PAGE>

     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 that fit your own risk and reward goals.
    

     III.  USAA's Family of Funds

   
     We offer  you  another  alternative  for  asset  allocation  with our asset
     strategy  funds listed on page 15.  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 which meets 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,
     bank  wire,  electronic  funds  transfer  (EFT),  phone,  or in  person.  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  Exchange 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  effectiveness  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.

     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  will be 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 will
     not be disbursed until 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.
   
     HOW TO REDEEM

     WRITTEN, FAX     * Send your written instructions to:
     TELEGRAPH, OR         USAA Shareholder Account Services

     Telephone  redemption is  automatically  established when you complete your
     application.  The Fund will employ  reasonable  procedures  to confirm that
     instructions  communicated by telephone are genuine, and if it does not, it
     may  be  liable  for  any  losses  due  to   unauthorized   or   fraudulent
     instructions.  Before any discussion  regarding your account, we obtain the
     following  information:  (1) USAA number or account number, (2) the name(s)
     on  the  account  registration,  and  (3)  social  security  number  or tax
     identification number for the account registration.  In addition, we record
     all telephone  communications  with you and send  confirmations  of account
     transactions  to the address of record.  Redemption by  telephone,  fax, or
     telegraph is not available for shares represented by stock certificates.
    

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

   
     Investor's Guide to USAA Mutual Fund Services

     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  purchase  information as well as more information on redemption
     of shares 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

10

<PAGE>

     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:

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

     *   limit or  discontinue  the offering  of shares  of any portfolio of the
         Company without notice to the shareholders;

     *   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);
         provided, 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;

     *   require a signature guarantee for purchases, redemptions, or changes in
         account  information in those instances where the  appropriateness of a
         signature authorization is in question. The SAI contains information on
         acceptable guarantors;

   
     *   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 that 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 10.
    

     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 that 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).

                                                                              11

SHAREHOLDER INFORMATION

     Share Price Calculation

   
     The price at which shareholders 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.
    

     When

     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. You may buy
     and sell Fund shares at the NAV per share without a sales charge.

     How

     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 gains
     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.  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 under
     Subchapter M of the Internal Revenue Code of 1986, as amended,  referred to
     as the Code. In compliance  with the Code,  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.

12

<PAGE>

     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,  including 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:

     * fails to furnish the Fund with a correct  tax  identification  number,  
     * underreports dividend or interest income, 
     * fails to certify that he 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 that you are not
     currently subject to backup withholding.
    

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

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 the Fund.
    

     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 the  shareholders of
     that specific fund.  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 communicating to other shareholders about the meeting.

                                                                              13

<PAGE>

                                  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 may also change
based on the price of the 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,   and  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. As a result, the value
of the  securities  will be affected by changes in the exchange rate between the
dollar and foreign currencies.  In managing currency exposure, we may enter into
forward currency contracts. A forward currency contract involves an agreement to
purchase  or sell a  specified  currency  at a  specified  future date or over a
specified time period at a price set at the time of the contract.

     X  You are interested in learning about investments.
     X  You are willing to accept moderate to high risk.
     X  You are looking for a long-term investment.

     This  fund may  NOT be  appropriate  as part  of your  investment portfolio

FEES AND EXPENSES

   
     This  summary  provides  information  to assist  you in  understanding  the
     expenses you will pay directly or indirectly to invest in the Fund.

     Shareholder Transaction Expenses -- Fees You Pay Directly

     There are no fees charged to your account when you buy,  sell, or hold Fund
     shares.  However,  if you  sell  shares  and  request  your  money  by wire
     transfer,  you  will pay a $10 fee.  (Your  bank may also  charge a fee for
     receiving wires.)

     Annual Fund Operating Expenses -- Fees You Pay Indirectly

     Unlike shareholder transaction charges, the Fund's expenses are not charged
     directly to your account, but instead are paid out of the Fund's assets and
     are  reflected in the Fund's share price and  dividends.  "Other  Expenses"
     such as  custodian  and  transfer  agent fees have been  estimated  for the
     Fund's  first year of  operation.  The figures  below are  calculated  as a
     percentage of average net assets.

        Management Fees                    .75%
        12b-1 Fees                         None
        Other Expenses (estimated)         .67%
                                          ----
        Total Fund Operating Expenses     1.42%
                                          ====
    

   * 12B-1 FEES -- SOME  MUTUAL  FUNDS  CHARGE  THESE  FEES TO PAY FOR THE COSTS
                   OF SELLING FUND SHARES.

     Example of Effect of Fund Operating Expenses

     You would pay the  following  expenses on a $1,000  investment in the Fund,
     assuming (1) 5% annual return and (2)  redemption at the end of the periods
     shown.

   
                 1 year........................     $ 14
                 3 years.......................       45
    

     THIS EXAMPLE IS NOT A REPRESENTATION  OF PAST OR FUTURE EXPENSES AND ACTUAL
     EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

Please  consider  performance  information  in  light of the  Fund's  investment
objective and policies and market  conditions  during the reported time periods.
Remember, historical performance may not be repeated in the future. The value of
your shares may go up or down. For the most current price and return information
for this Fund,  you may call  TouchLINE(R)  at  1-800-531-8777.  Press 1 for the
Mutual Fund Menu, press 1 again for prices and returns.  Then, press 32 followed
by the pound sign when asked for a Fund Code.

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 dividends
and  distributions of capital gains. 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. 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 are  accompanied  by a higher risk of losing  money.  The
     reverse is also generally true: the lower the potential  reward,  the lower
     the risk.  However,  as you consider an investment in the Fund,  you should
     also take into account your  tolerance  for the daily  fluctuations  of the
     stock  market  and  whether  you can  afford  to leave  your  money in this
     investment for long periods of time to ride out down periods.

[CAUTION LIGHT]

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

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.

<PAGE>

          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 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 we invest the Fund's assets?

     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 we prohibited from investing the Fund's assets 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]

    Market Risk. Because this Fund invests in equity  securities,  it is subject
    to market  risk.  Stock  prices in general  may  decline  over short or even
    extended  periods,  regardless  of the  success  or  failure  of  individual
    companies' operations. The stock market tends to run in cycles, with periods
    when stock prices generally go up and periods when stock prices generally go
    down. Equity securities tend to go up and down more than bonds.

                                                                               5

<PAGE>

[CAUTION LIGHT]

    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 investments in which we may invest
    the Fund's assets, see Appendix A on page 14.
    

     Investment Restrictions

     The following restrictions may only be changed with shareholder approval:

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

     *  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.

     *  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 (SAI).

FUND MANAGEMENT

   
     The Board of Directors of USAA Mutual Fund,  Inc.  (Company),  of which the
     Fund is a series,  supervises  the  business  affairs of the  Company.  The
     Company has retained us, USAA Investment  Management  Company,  to serve as
     the manager and distributor of the Company.

     We are an affiliate of United Services  Automobile  Association  (USAA),  a
     large,  diversified financial services institution.  As of the date of this
     Prospectus,  we  had  approximately  $35  billion  in  total  assets  under
     management. Our mailing address is 9800 Fredericksburg Rd., San Antonio, TX
     78288.

     We provide management services to the Fund. We are responsible for managing
     the Fund's  portfolio  (including  placement of  brokerage  orders) and its
     business affairs,  subject to the authority of and supervision by the Board
     of Directors.  For our  services,  the Fund pays us an annual fee. The fee,
     three-fourths of one percent (.75%) of average net assets, is accrued daily
     and paid monthly.

     In addition to the fees paid pursuant to the Advisory Agreement, the Fund's
     operating  expenses  generally  consist of  expenses  for the  issuing  and
     redeeming of Fund shares,  transfer agent and custodian  charges,  auditing
     and legal expenses,  certain expenses of registering and qualifying  shares
     for sale,  fees of Directors who are not  affiliated  with us, and costs of

     reports to existing shareholders.

     We  also  provide  distribution   services  to  the  Fund  and  receive  no
     compensation for those services.

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

     Portfolio Transactions

     USAA  Brokerage  Services,  our  discount  brokerage  service,  may execute
     purchases  and sales of equity  securities  for the Fund's  portfolio.  The
     Board of Directors has adopted  procedures  to ensure that any  commissions
     paid to USAA Brokerage Services are reasonable and fair.

     Portfolio Manager

     The following individual is primarily responsible for managing the Fund.

     Curt  Rohrman,   Assistant  Vice  President  of  Equity  Investments  since
     September  1996,  is the  portfolio  manager.  He has ten years  investment
     management experience and has worked for us for two years. Prior to joining
     us, Mr.  Rohrman worked for CS First Boston  Corporation  from June 1988 to
     March 1995. He earned the Chartered  Financial Analyst (CFA) designation in
     1991 and is a member  of the  Association  for  Investment  Management  and
     Research  (AIMR)  and the San  Antonio  Financial  Analysts  Society,  Inc.
     (SAFAS).  He holds an MBA from the  University of Texas at Austin and a BBA
     from Texas Christian University.

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.

                                                                               7

<PAGE>

   
     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 that fit your own risk and reward goals.
    
     III.  USAA's Family of Funds
   
     We offer  you  another  alternative  for  asset  allocation  with our asset
     strategy  funds  listed on page 15. 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 which meets 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,
     bank  wire,  electronic  funds  transfer  (EFT),  phone,  or in  person.  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  Exchange 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  effectiveness  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.

     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  will be 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 will
     not be disbursed until 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.

     HOW TO REDEEM

   
     WRITTEN, FAX     * Send your written instructions to:
     TELEGRAPH, OR         USAA Shareholder Account Services

     Telephone  redemption is  automatically  established when you complete your
     application.  The Fund will employ  reasonable  procedures  to confirm that
     instructions  communicated by telephone are genuine, and if it does not, it
     may  be  liable  for  any  losses  due  to   unauthorized   or   fraudulent
     instructions.  Before any discussion  regarding your account, we obtain the
     following  information:  (1) USAA number or account number, (2) the name(s)
     on  the  account  registration,  and  (3)  social  security  number  or tax
     identification number for the account registration.  In addition, we record
     all telephone  communications  with you and send  confirmations  of account
     transactions  to the address of record.  Redemption by  telephone,  fax, or
     telegraph is not available for shares represented by stock certificates.
    

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

   
     Investor's Guide to USAA Mutual Fund Services

     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  purchase  information as well as more information on redemption
     of shares 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

10

<PAGE>

     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:

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

     *   limit or  discontinue the  offering of  shares of  any portfolio of the
         Company without notice to the shareholders;

     *   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);
         provided, 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;

     *   require a signature guarantee for purchases, redemptions, or changes in
         account  information in those instances where the  appropriateness of a
         signature authorization is in question. The SAI contains information on
         acceptable guarantors;

   
     * 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 that 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 10.
    

     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 that 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).

                                                                              11

SHAREHOLDER INFORMATION

     Share Price Calculation

   
     The price at which shareholders 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.
    

     When

     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. You may buy
     and sell Fund shares at the NAV per share without a sales charge.

     How

     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 gains
     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.  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 under
     Subchapter M of the Internal Revenue Code of 1986, as amended,  referred to
     as the Code. In compliance  with the Code,  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.

12

<PAGE>

     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,  including 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:

     * fails to furnish the Fund with a correct tax identification number,
     * underreports dividend or interest income,
     * fails to certify that he 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 that you are not
     currently subject to backup withholding.
    

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

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 the Fund.
    

     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 the  shareholders of
     that specific fund.  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 communicating to other shareholders about the meeting.

                                                                              13

<PAGE>

                                   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 may also change
based on the price of the 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,   and  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. As a result, the value
of the  securities  will be affected by changes in the exchange rate between the
dollar and foreign currencies.  In managing currency exposure, we may enter into
forward currency contracts. A forward currency contract involves an agreement to
purchase  or sell a  specified  currency  at a  specified  future date or over a
specified time period at a price set at the time of the contract.

                             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 cancelled due to nonpayment or if the Company
does not receive good funds either by check or electronic  funds  transfer,  the
cancellation will be treated 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,  shares can be redeemed  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

Fund shares may be transferred to another person by sending written instructions
to USAA  Shareholder  Account  Services  (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,  an application  must be completed and returned to the
Transfer Agent.

              ADDITIONAL INFORMATION REGARDING REDEMPTION OF SHARES

The value of a shareholder's 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 the  shareholder.  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 the
last known address of the shareholder.

     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 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 following investment plans are made available by the Company 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 low  initial  investment  purchase  plan  for  the  Science  &
Technology Fund. With this plan the regular minimum initial investment amount is
waived if you make an initial  investment as low as $100 with subsequent monthly
additions of at least $50 through  electronic  funds transfer from a checking or
savings account.
    

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),   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 a shareholder
to engage in dollar-cost  averaging.  For additional  information concerning the
benefits of dollar-cost averaging, see APPENDIX C.

SYSTEMATIC WITHDRAWAL PLAN

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,
shareholders  may choose to have

                                       3

<PAGE>

withdrawals   electronically   deposited  at  their  bank  or  other   financial
institution. They may also elect to have checks mailed to a designated address.

   
     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.  The  shareholder  may
terminate  participation  in the plan at any  time.  There is no  charge  to the
shareholder 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 selected by the shareholder 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 a shareholder's  investment and eventually  exhaust the account.  Reinvesting
dividends and  distributions  helps replenish the account.  Because share values
and  net  investment  income  can  fluctuate,  shareholders  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 the shareholder's income tax return. Therefore, a shareholder 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 an investor  qualifies  for
certain types of retirement programs.  For the convenience of the investor,  the
following plans are made available by the Manager:  IRA (including  SEP/IRA) and
403(b)(7)  accounts.  The minimum  initial  investment in each of these plans is
$250 or minimum  $100 with a minimum $50 monthly  electronic  investment  in the
Science & Technology  Fund or minimum $20 with a minimum $20 monthly  electronic
investment in the First Start Growth Fund. Subsequent investments of $50 or more
in the Science & Technology  Fund and $20 or more in the First Start Growth Fund
may be made at any time.  Investments  may be made 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 Rd., 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  proceeds  of  a
distribution   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 the
investor 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.  Detailed
information about the plans may be obtained 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.

                                        4

<PAGE>

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 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  involves 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  shareholders  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.

                                       5

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  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 may also change based on the
price of the common stock.

     The  convertible  securities  in which  each Fund will  invest may 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 and
are applicable to 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 for industries 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 each
Fund.  This  additional  restriction may be changed by the Board of Directors of
the Company 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.

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.

   
     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  and  short-term  U.S.  Government  securities  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.

     The assets of each Fund 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

                                       7

<PAGE>

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 in order 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 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  January  1,  1996,  C. Dale  Briscoe  retired  from the Board of
     Directors  and  effective  December 31, 1996,  George E. Brown retired from
     the Board of Directors.

 **  Effective  December 1, 1996, Robert G. Davis replaced M. Staser Holcomb as
     Director and  Chairman of the Board of Directors.

(a)  The USAA Family of  Funds has accrued  deferred  compensation for Mr. Brown
     in an amount  (plus  earnings  thereon) of $21,525.  The  compensation  was
     deferred  by Mr. Brown pursuant to a  non-qualified  Deferred  Compensation
     Plan, under which deferred  amounts accumulate  interest quarterly based on
     the  annualized  U.S.  Treasury  Bill rate in effect on the last day of the
     quarter.  Amounts deferred  and accumulated earnings thereon are not funded
     and  are general  unsecured  liabilities  of the USAA Funds until paid. The
     Deferred  Compensation Plan was  terminated in 1988 and no compensation has
     been  deferred  by any  Director/Trustee  of the USAA Family of Funds since
     the Plan was terminated.

(b)  M. Staser  Holcomb,  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.

(c)  At July 31, 1996,  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  five 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
for which IMCO serves as investment adviser. 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.

                              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  $35  billion,  of which
approximately $20 billion were in mutual fund portfolios.
    

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

                                       11

<PAGE>

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 typesetting,  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.

INDEPENDENT AUDITORS

KPMG Peat Marwick LLP, 112 East Pecan, Suite 2400, San Antonio, TX 78205, is the
Company's  independent  auditor.  In this capacity,  the firm is responsible for
auditing the annual financial statements of each Fund and reporting thereon.

                         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:

                                       12

<PAGE>

                                 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.

                                       13

<PAGE>

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.

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

DUFF & PHELPS (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.

                                       14

<PAGE>

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.

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+.

                                       15

<PAGE>

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.
