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 to seek a conservative  balance for the
     investor  between  income,  the  majority of which is exempt  from  federal
     income tax, and the potential  for long-term  growth of capital to preserve
     purchasing  power. We will use an asset allocation  strategy to achieve the
     Fund's  objective.  See  INVESTMENT  POLICIES  AND RISKS on page 6 for more
     information.

WILL THE VALUE OF YOUR INVESTMENT FLUCTUATE?

     Yes, it will. The value of your investment could increase or decrease.  The
     bar chart and table  shown  below  illustrate  the Growth and Tax  Strategy
     Fund's risks and performance by showing  changes in the Fund's  performance
     from year to year over the life of the Fund and by  showing  how the Fund's
     average  annual  returns  for one and five  years  and the life of the Fund
     compare to those of a broad-based securities market index. How the Fund has
     performed in the past is not necessarily an indication of how the Fund will
     perform in the future.

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.  The figures below
     show  actual  expenses  incurred  during the past fiscal year ended May 31,
     1997, and are calculated as a percentage of average net assets.

Please  consider  performance  information  in  light of the  Fund's  investment
objective and policies and market  conditions  during the reported time periods.

FINANCIAL HIGHLIGHTS

     Please read the Fund's Annual Report  furnished  with and  incorporated  by
     reference  into this  Prospectus  for financial  information  including the
     Fund's  financial  statements  audited by KPMG Peat Marwick LLP. The Annual
     Report  includes  messages  from the  President  and the  Fund's  portfolio
     managers, a listing of the Fund's investments,  and additional  performance
     information you may wish to review.

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 and bond  markets  and  whether you can afford to leave your money in
     this investment for long periods of time to ride out down periods.

                                                                               5

     information about the main risks that you will face as a shareholder of the
     Fund.

     (medium color) 41-59%
     (dark color)   41-49%
     (light color)   0-10%

     The ranges allow for a variance within each investment category.  The Board
     of Trustees may revise the target ranges upon 60 days' prior written notice
     to  shareholders.  However,  we reserve the right to revise the ranges on a
     temporary  defensive  basis without  shareholder  notification  whenever we
     believe  such  changes  to be in the  best  interest  of the  Fund  and its
     shareholders.

     Q     Why do we mix stocks and bonds in the same Fund?

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

     Q    What actions do we take to keep the Fund's asset  allocations  within
          the target  ranges?

     A    If market  action  causes the actual assets of the Fund in one or more
          investment  categories  to move  outside  the  ranges,  we  will  make
          adjustments to rebalance the portfolio.  In general, we will rebalance
          the portfolio at least once during each quarter.  In  rebalancing  the
          Fund's portfolio,  we will buy or sell securities to return the actual
          allocation  of the  Fund's  assets to within its  target  ranges.  For
          example,  the Fund's  portfolio  could begin a quarter with its assets
          allocated 50% in the Tax-Exempt  Bonds category,  45% in the Blue Chip
          Stocks  category,  and 5% in the Tax-Exempt  Money Market  Instruments
          category.  During the quarter,  a strong  stock market  coupled with a
          weak bond market could leave the portfolio  with 40% in the Tax-Exempt
          Bonds category,  55% in the Blue Chip Stocks  category,  and 5% in the
          Tax-Exempt Money Market  Instruments  category.  In this case we would
          sell  blue  chip  stocks  and  use  the  proceeds  to  buy  tax-exempt
          securities  in order to bring the blue chip  stocks back to within the
          41-49% target range.

[CAUTION LIGHT]

    REBALANCING  RISKS.  In  purchasing  and  selling  securities  in  order  to
    rebalance  its  portfolio,  the Fund will pay more in brokerage  commissions
    than it would  without  a  rebalancing  policy.  As a result  of the need to
    rebalance, the Fund also has less flexibility in the timing of purchases and
    sales of securities  than it would  otherwise.  Although we intend to manage
    the Fund in a tax-advantaged  manner,  the Fund may have a higher proportion
    of  capital  gains  and a lower  return  than a fund  that  does  not have a
    rebalancing policy.

     Q    How did we select the investment  categories  and target ranges?  

     A    We have specifically selected the investment categories and the target
          ranges to provide investors with a diversified  investment in a single
          mutual  fund.  Tax-exempt  bonds  provide  income  exempt from federal
          income tax.  Tax-exempt money market  instruments  provide a means for
          temporary  investment of cash balances arising in the normal course of
          business. Blue chip stocks provide the potential for long-term capital
          growth.

          It is a fundamental policy of  the  Fund  that  during  normal  market
          conditions, the Fund's assets will be invested so that at least 50% of
          the Fund's annual income will be exempt from federal  personal  income
          tax and excluded from the calculation of federal  alternative  minimum
          taxes for individual taxpayers.

     TAX-EXEMPT BONDS AND TAX-EXEMPT MONEY MARKET INSTRUMENTS

     Q    What kind of municipal obligations are included in the portfolio?

     A    Typical  issuers  of  municipal  obligations  may  include  cities and
          counties,   municipally-owned  utilities,  school districts,  colleges
          and universities, and hospitals.

                                                                               7

<PAGE>

           GENERAL OBLIGATION BONDS
           Secured by the issuer's pledge of its faith,  credit and taxing power
           for the payment of principal and interest.

           REVENUE BONDS
           Payable from the revenue derived from a particular  facility or class
           of facilities  or, in some cases,  from proceeds of a special  excise
           tax or other specific revenue source, but not from the general taxing
           power.

           INDUSTRIAL DEVELOPMENT BONDS
           Issued  by or on behalf of  public  authorities  to obtain  funds for
           privately-operated  facilities,  provided  that the interest  paid on
           such securities qualifies as exempt from federal income taxes.

     Q     What tax-exempt bonds are included in the portfolio?

     A     The Tax-Exempt Bonds category  includes  municipal  obligations which
           will have a  remaining  maturity at the time of purchase in excess of
           one year.  Although the average portfolio  maturity of the securities
           in this category is not restricted, we expect it to exceed ten years.
           In determining a security's  maturity for purposes of calculating the
           Fund's  average  maturity,  we may use estimates of the expected time
           for its principal to be paid. This can be substantially  shorter than
           its stated final maturity.

[CAUTION LIGHT]

          INTEREST  RATE RISK.  As a mutual fund investing in bonds, the Fund is
          subject  to  the risk (sometimes called "interest rate risk") that the
          market value of the bonds will decline due to rising  interest  rates.
          Bond prices are linked to  the prevailing  market interest  rates.  In
          general,  when interest  rates rise, the prices of bonds fall and when
          interest rates fall, bond prices  generally rise. The price volatility
          of  a  bond  also depends on its  maturity.  Generally, the longer the
          maturity of a bond, the greater its sensitivity to interest rates.  To
          compensate investors for this higher risk, bonds with longer  maturity
          generally  offer higher yields than bonds with shorter maturity.

     Q    What  tax-exempt   money  market   instruments  are  included  in  the
          portfolio?

     A    The tax-exempt  money market  instruments in the portfolio  consist of
          high-quality,  tax-exempt  debt securities of the type included in the
          Tax-Exempt  Bonds category.  All tax-exempt  money market  instruments
          have remaining  stated  maturities at the time of purchase of one year
          or less or are subject to puts or similar demand  features that result
          in an effective maturity of one year or less.

<PAGE>

     Q     What are the credit ratings of these securities?

     A    At least 50% of the  combined  total market  values of the  tax-exempt
          bonds and tax-exempt money market instruments will be rated within the
          three highest long-term rating categories by:

           * Moody's Investors Service, Inc. (Moody's),
           * Standard & Poor's Ratings Group (S&P), or
           * Fitch Investors Service, Inc. (Fitch)

           or in the highest short-term rating category by:

           * Moody's,
           * S&P, or
           * Fitch

          or . . . if  unrated by  those  three agencies, we must determine that
          these securities are of equivalent investment quality.

          However,  we   will  only  purchase  tax-exempt  securities  that  are
          considered   investment  grade.   For  a  security  to  be  considered
          investment grade, it must be:

           *  rated  by  one  or  more  rating  agencies at  least in the fourth
              highest rating category for long-term securities;

           *  rated  by  one or  more rating agencies at least within the second
              highest rating category for short-term securities;

           *  or, if not  rated by those rating agencies, determined by us to be
              of equivalent investment quality.

[CAUTION LIGHT]

    CREDIT RISK.  The bonds in the Fund's  portfolio are subject to credit risk.
    Credit  risk is the  possibility  that an issuer of a bond will fail to make
    timely payments of interest or principal. We believe that the credit risk of
    the Fund is minimized by the fact that all of the  tax-exempt  securities in
    the Fund's  portfolio  must be  considered  investment  grade at the time of
    purchase. In addition, our analysts evaluate the credit risks and its impact
    on portfolio  securities  in which the Fund may invest.  Nevertheless,  even
    investment-grade  tax-exempt  securities  are subject to some  credit  risk.
    Bonds  in  the  lowest-rated  investment  grade  category  have  speculative
    characteristics.  Changes in economic  conditions or other circumstances are
    more likely to lead to a weakened  capability to make principal and interest
    payments  on  these  bonds  than is the  case  for  higher-rated  bonds.  In
    addition,  the ratings of securities are estimates by the rating agencies of
    the credit quality of the  securities.  The ratings do not take into account
    certain other risks or guarantees  that interest or principal will be repaid
    on a timely basis.

                                                                               9

<PAGE>

     Q     What happens if the rating of a security is downgraded?

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

     Q    May the Fund hold any taxable debt securities?

     A    We may, on a temporary basis due to market or other conditions, invest
          the Fund's assets without limitation in money market instruments which
          are subject to federal  income tax.  These  securities  may consist of
          obligations   of   the   U.S.   Government   and   its   agencies   or
          instrumentalities,   and   repurchase   agreements   secured  by  such
          instruments;  certificates  of deposit  of  domestic  banks;  banker's
          acceptances; commercial paper; and other corporate debt obligations.

     Q    How  do we intend to minimize  the impact of federal  income  taxes on
          the Fund's shareholders?

     A    We  intend to use various techniques to minimize the impact of federal
          income  taxes on  the Fund's  shareholders  while  maximizing  capital
          appreciation, including:

           *   investing in bonds and similar  instruments  that provide  income
               which is exempt from federal income tax;

           *   investing in blue chip stocks with low dividend yields;

           *   selecting  blue chip stocks that we expect to hold for relatively
               long  periods to minimize  the cost of trading and the receipt of
               capital gains;

           *   when  selling blue chip  stocks,  considering  the sale of stocks
               with the  highest  tax cost  basis to  minimize  the  receipt  of
               capital gains; and

           *   offsetting  capital  gains  with capital losses, if available and
               appropriate.

[CAUTION LIGHT]

    TAXABLE INCOME.  Although the Fund seeks to minimize  taxable income and the
    realization  of capital gains,  the Fund may  nevertheless  receive  taxable
    income and capital gains from time to time.  Additionally,  shareholders may
    owe taxes on capital gains realized, if any, upon redemption of Fund shares.

[CAUTION LIGHT]

    CHANGES IN LAWS.  Actual or  anticipated  changes  in federal  tax laws that
    restrict or eliminate the  tax-exempt  status of securities of the type held
    by the Fund could result in increased price volatility of these  securities.
    These changes in law could also reduce the tax-exempt  securities  available
    for investment by the Fund. Changes in law affecting the taxing and spending
    authority of a municipality that issued a tax-exempt

10

<PAGE>

    security  held by the Fund could affect the ability of the  municipality  to
    make payments of principal and interest on the security.

    BLUE CHIP STOCKS

    We  will invest 41-49% of the Fund's assets in equity securities  (common or
    preferred  stocks) or  securities  convertible  into equity  securities  for
    long-term growth.

     Q    What  are  the  characteristics  of  the  equity  securities  in  this
          category?

     A    A blue chip stock is an equity security of a company that has a market
          capitalization of:

          *   at  least $500  million and is  included in the list of  companies
              that  make up the  Standard & Poor's  500  Composite  Stock  Price
              Index or the Dow Jones Industrial Average; or

          *   at least $1 billion.

     We may invest up to 5% of the Fund's  total  assets in blue chip  stocks of
     foreign  issuers  or  in  American  Depositary   Receipts  (ADRs),   Global
     Depositary  Receipts  (GDRs),  or similar  forms of  ownership  interest in
     securities of foreign issuers that are traded on U.S. securities  exchanges
     or in U.S. over-the-counter markets.

[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.

    For additional  information  about other  investments in which we may invest
    the Fund's assets, see Appendix A on page 22.

    Investment Restrictions

    The following restrictions may only be changed with shareholder approval:

    *   The Fund may not invest more than 25% 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).

USING MUTUAL FUNDS IN AN ASSET ALLOCATION PROGRAM

     I. The Idea Behind Asset Allocation

     If you have money to invest and hear that stocks may be a good  investment,
     is it a wise idea to use your entire savings to buy one stock?  Most people
     wouldn't -- it would be fortunate if it works,  but this  strategy  holds a
     great deal of risk.  Surprising  news could be  reported  tomorrow  on your
     stock, and its price could soar or plummet.

     Careful  investors  understand  this concept of risk and lower that risk by
     diversifying their holdings among a number of securities. That way bad news
     for one  security  may be  counterbalanced  by good  news  regarding  other
     securities.  But there is still a question of risk here.  History  tells us
     that stocks are generally more volatile than bonds and that long-term bonds
     are generally more volatile than  short-term  bonds.  History also tells us
     that over many years  investments  having  higher risks tend to have higher
     returns than  investments that carry lower risks.  From these  observations
     comes the idea of asset allocation.

                                                                              13

<PAGE>

     Asset  allocation  is a concept  that  involves  dividing  your money among
     several different types of investments -- for example,  stocks,  bonds, and
     short-term investments such as money market instruments -- and keeping that
     allocation  until your  objectives or the financial  markets  significantly
     change.  That way  you're not  pinning  all your  financial  success on the
     fortunes  of  one  kind  of  investment.   Money  spread  across  different
     investment  categories  can help you reduce  market  risk and  likely  will
     provide more stability to your total return.

     Asset allocation can work because different kinds of investments  generally
     follow different up- and-down cycles. With a variety of investments in your
     portfolio, some are probably doing well, even when others are struggling.

     II.  Using Asset Allocation in an Investment Program

     Most  investors  understand  the  concept  of  diversification,  but  asset
     allocation goes beyond  diversifying  your portfolio;  it's much more of an
     active process. You must evaluate your lifestyle, finances,  circumstances,
     long- and short-term  financial  goals,  and tolerance for investment risk.
     Once  you  have  structured  your  allocation,  you'll  need to  review  it
     regularly  since your  objectives  will change over time. Even though we do
     not charge sales loads or commissions, our sales representatives are always
     available  to assist  you in  structuring  and  reviewing  your  investment
     portfolio.

     III.  USAA's Series of Asset Strategy Funds

     USAA's series of asset  allocation  funds,  our Asset Strategy  Funds,  are
     designed for the  long-term  investor  and are in line with our  investment
     philosophy for investors,  specifically  "buy and hold for the  long-term,"
     and "don't  try to time the  market."  As shown on the next  page,  each of
     USAA's  Asset  Strategy  Funds  has its own  different  mix of  assets  and
     objectives.

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.

                                                                              15

<PAGE>

     EFFECTIVE DATE

     When you make a purchase,  your purchase  price will be the net asset value
     (NAV) per share next  determined  after the Fund  receives  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
     NYSE each day the Exchange is open. If the Fund receives your request prior
     to that time, your purchase price will be the NAV per share  determined for
     that day.  If the Fund  receives  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.

     MINIMUM INVESTMENTS

     INITIAL PURCHASE        $3,000   or   if  you   elect   to   have  monthly
                             electronic investments of  at least $50 each, only
                             $100 is required to open an account.  Employees of
                             USAA, its affiliates, or subsidiaries may open  an
                             account through payroll deduction for as little as
                             $25 per pay period with no initial investment.

     REDEMPTION OF SHARES

     You may redeem Fund shares by any of the methods described below on any day
     the NAV per share is calculated.  Redemptions  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 Trust may elect to suspend the  redemption  of shares or
     postpone the date of payment in limited circumstances.

     HOW TO REDEEM

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 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).

     Trust Rights

     The Trust reserves the right to:

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

     *   limit or  discontinue  the  offering of  shares of any portfolio of the
         Trust without notice to the 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 $900, 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 17.

<PAGE>

     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).

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  quarterly.  Any net capital
     gains distribution  usually occurs within 45 days of the May 31 fiscal year
     end which would be somewhere  around the middle of July. 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
     which is two business days before the quarter end. 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.

                                                                              19
<PAGE>

     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.

     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 the  investor  has 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.

     Distributions to shareholders  derived from tax-exempt interest received by
     the Fund will be excluded  from a  shareholder's  gross  income for federal
     income tax purposes, provided the Fund meets certain requirements.

     IN CERTAIN INSTANCES TAX-EXEMPT INTEREST HAS TAX IMPLICATIONS.

     Although  otherwise  exempt from  federal  tax,  tax-exempt  interest  from
     private activity bonds (for example,  industrial development revenue bonds)
     issued  after  August 7,  1986,  is treated  as a tax  preference  item for
     purposes of the alternative minimum tax.

     For corporations, all tax-exempt interest will be considered in calculating
     the alternative minimum tax as part of the adjusted current earnings.

     Distributions of tax-exempt income are considered in computing the portion,
     if any, of Social  Security and  railroad  retirement  benefits  subject to
     federal and, in some cases, state taxes.

     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.

20

<PAGE>

     REPORTING - The Fund will report annually to its  shareholders  the federal
     tax status of  dividends  and  distributions  paid or  declared by the Fund
     during the preceding calendar year including:

     * the portion of the dividends  constituting  interest on private  activity
       bonds; 
     * the percentage and source, on a state-by-state  basis, of interest income
       earned  on the tax-exempt securities, if any, held by the Fund during the
       preceding year.

DESCRIPTION OF SHARES

     The Fund is a series of USAA  Investment  Trust (Trust) and is diversified.
     The Trust is an open-end  management  investment  company  established as a
     business trust under the laws of the  Commonwealth  of  Massachusetts.  The
     Trust is  authorized  to issue an unlimited  number of shares of beneficial
     interest of separate portfolios, each of which is commonly referred to as a
     mutual fund.  There are 11 mutual funds in the Trust,  including the Growth
     and Tax Strategy Fund.

     The Trust does not hold  annual or regular  meetings  of  shareholders  and
     holds special  meetings only as required by the  Investment  Company Act of
     1940.  The Trustees may fill vacancies on the Board or appoint new Trustees
     if the result is that at least  two-thirds  of the Trustees 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
     Trust,  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 Trust may request a  shareholder  meeting at any time for the
     purpose  of voting to remove  one or more of the  Trustees.  The Trust will
     assist communicating to other shareholders about the meeting.

                                                                              21

                                   APPENDIX A

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

WHEN-ISSUED SECURITIES
We may invest in new issues of debt securities offered on a when-issued basis.

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

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

*    Such securities can be sold before settlement date.

VARIABLE RATE SECURITIES
We may invest in  securities  that bear  interest  at rates  which are  adjusted
periodically to market rates.

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

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

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

PUT BONDS
We may invest in  tax-exempt  securities  (including  securities  with  variable
interest  rates)  which may be  redeemed or sold back (put) to the issuer of the
security or a third party prior to stated maturity (put bonds).

*    Such securities will normally trade as if maturity is the earlier put date,
     even  though  stated  maturity  is  longer.   Under  the  Fund's  portfolio
     allocation  procedure,  maturity  for put bonds is deemed to be the date on
     which the put becomes exercisable.

ZERO COUPON BONDS
We may invest in zero coupon bonds.

*    A zero coupon bond is a security  that is sold at a deep  discount from its
     face value,  makes no periodic interest  payments,  and is redeemed at face
     value when it matures.

*    The lump sum payment at maturity increases the price volatility of the zero
     coupon  bond to changes in  interest  rates  when  compared  to a bond that
     distributes a semiannual coupon payment.

*    In  calculating  its  dividend,  the  Fund  records  as  income  the  daily
     amortization of the purchase discount.

MUNICIPAL LEASE OBLIGATIONS
We may invest in a variety of  instruments  commonly  referred  to as  municipal
lease obligations, including:

*    Leases
*    Installment purchase contracts

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.

                             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.

   
     A 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  securities of the Income  Strategy,  Growth and Tax Strategy,
Balanced  Strategy,  Cornerstone  Strategy,  Growth Strategy,  Emerging Markets,
Gold, International,  and World Growth Funds and the GNMA Trust 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 and  government  securities  are valued each  business day by a
      pricing  service  (the  Service)  approved by the Board of  Trustees.  The
      Service  uses the mean  between  quoted  bid and asked  prices or the last
      sales price to price  securities  when, in the Service's  judgment,  these
      prices are readily  available and are  representative  of the  securities'
      market values. For many securities, such prices are not readily available.
      The Service  generally  prices  those  securities  based on methods  which
      include  consideration  of yields or prices of  securities  of  comparable
      quality,  coupon, maturity and type, 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
      Trustees.

     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 a Fund's NAV therefore
may not take place  contemporaneously  with the  determination  of the prices of
securities held by a 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 a Fund's NAV is calculated will not be reflected in
a 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  Trustees,  will use all  relevant  available  information  to
determine a fair value for the affected portfolio securities.

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

      The valuation of the Treasury Money Market Trust's  portfolio  instruments
based upon their  amortized  cost is subject to the Fund's  adherence to certain
procedures and conditions.  Consistent with regulatory requirements, the Manager
will only purchase securities with remaining  maturities of 397 days or less and
will maintain a dollar-weighted  average  portfolio  maturity of no more than 90
days.  The Manager will invest only in securities  that have been  determined to
present  minimal  credit risk and that  satisfy the quality and  diversification
requirements of applicable  rules and regulations of the Securities and Exchange
Commission (SEC).

      The Board of Trustees has established procedures designed to stabilize the
Treasury  Money Market  Trust's price per share,  as computed for the purpose of
sales and redemptions,  at $1.00. There can be no assurance,  however,  that the
Fund will at all times be able to maintain a constant $1.00 NAV per share.  Such
procedures  include review of the Fund's holdings at such intervals as is deemed
appropriate to determine  whether the Fund's NAV  calculated by using  available
market quotations deviates from $1.00 per share and,

                                        2

<PAGE>

if so,  whether such  deviation may result in material  dilution or is otherwise
unfair to existing shareholders.  In the event that it is determined that such a
deviation  exists,  the Board of Trustees will take such corrective action as it
regards as necessary and appropriate.  Such action may include selling portfolio
instruments  prior to maturity to realize  capital gains or losses or to shorten
average portfolio  maturity,  withholding  dividends,  or establishing a NAV per
share by using available market quotations.


   
                      CONDITIONS OF PURCHASE AND REDEMPTION

NONPAYMENT

If any order to purchase  shares is cancelled  due to nonpayment or if the Trust
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  Trustees  may  cause the  redemption  of an  account  with a
balance of less than $900,  provided that (1) the value of such account has been
reduced below the minimum initial  investment  required in such Fund at the time
of the establishment of the account to less than $900 entirely for reasons other
than  market  action,  (2) the account has  remained  below the minimum  initial
investment 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 Trustees.  Prompt payment will
be made by mail to the last known address of the shareholder.

      The  Trust  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  Trust  normally  utilizes  is
restricted,  or an emergency exists as determined by the SEC so that disposal of
the  Trust's   investments  or  determination  of  its  NAV  is  not  reasonably
practicable,  or (3) for such  other  periods as the SEC by order may permit for
protection of the Trust's shareholders.

   
      For the mutual  protection  of the investor  and the Funds,  the Trust 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.
    

REDEMPTION BY CHECK

   
Shareholders  in the  Treasury  Money  Market  Trust may request  that checks be
issued  for their  accounts.  Checks  must be  written in the amount of at least
$250.
    

      Checks issued to  shareholders  of the Treasury Money Market Trust will be
sent only to the person in whose name the account is registered  and only to the
address of record. The checks must be manually signed by the registered owner(s)
exactly as the account is registered. For joint accounts the signature of either
or both joint  owners will be required on the check,  according  to the election
made  on the  signature  card.  Dividends  will  continue  to be  earned  by the
shareholder until the shares are redeemed by the presentation of a check.

                                        3

<PAGE>

   
      When a check is presented to USAA Shareholder  Account Services  (Transfer
Agent) for payment,  a sufficient  number of full and  fractional  shares in the
investor's  account  will be  redeemed  to cover the  amount  of a check.  If an
investor's  account is not  adequate  to cover the amount of a check,  the check
will be returned  unpaid.  Because the value of the account changes as dividends
are accrued on a daily basis, checks may not be used to close an account.

     The Transfer  Agent will return to the  shareholder  checks paid during the
month by  separate  mail.  The  checkwriting  privilege  will be  subject to the
customary  rules and  regulations  of State Street Bank and Trust Company (State
Street Bank or the Custodian) governing checking accounts. There is no charge to
the shareholder for the use of the checks or for subsequent reorders of checks.
    

      The  Trust  reserves  the  right to  assess a  processing  fee  against  a
shareholder's  account  for any  redemption  check not  honored by a clearing or
paying agent.  Currently,  this fee is $15 and is subject to change at any time.
Some examples of such dishonor are improper  endorsement,  checks written for an
amount less than the minimum check amount,  and  insufficient  or  uncollectible
funds.

      The Trust,  the  Transfer  Agent,  and State  Street Bank each reserve the
right to change or suspend  the  checkwriting  privilege  upon 30 days'  written
notice to participating shareholders.


                                INVESTMENT PLANS

The following  investment  plans are made available by the Trust to shareholders
of all the Funds.  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.  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 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 Trust 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

                                        4

<PAGE>

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 (NOT available in the Growth and Tax Strategy
Fund)

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.
Subsequent  investments  of $50 or more  per  account  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 Investment Trust and USAA Mutual Fund, Inc.

   
      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  of 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   INVESTMENT  OBJECTIVE  AND  POLICIES  in  each  Fund's
Prospectus  (INVESTMENT  POLICIES AND RISKS in the Growth and Tax Strategy  Fund
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

The Income Strategy,  Balanced  Strategy and Growth Strategy Funds 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.  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,  except the GNMA Trust and the Treasury Money Market Trust, may
also  purchase   restricted   securities   eligible  for  resale  to  "qualified
institutional  buyers"  pursuant to Rule 144A under the  Securities  Act of 1933
(Rule 144A Securities).  Rule 144A provides a non-exclusive safe harbor from the
registration  requirements  of the Securities Act of 1933 for resales of certain
securities to institutional investors.

MUNICIPAL LEASE OBLIGATIONS

The Income  Strategy,  Balanced  Strategy,  Growth  Strategy  and Growth and Tax
Strategy Funds may invest in municipal lease obligations,  installment  purchase
contract  obligations,  and  certificates of  participation  in such obligations
(collectively,  lease  obligations).  A lease  obligation  does not constitute a
general obligation of the municipality for which the municipality's taxing power
is  pledged,   although  the  lease  obligation  is  ordinarily  backed  by  the
municipality's  covenant  to  budget  for  the  payments  due  under  the  lease
obligation.

      Certain  lease  obligations  contain   "non-appropriation"  clauses  which
provide  that  the  municipality  has no  obligation  to make  lease  obligation
payments in future  years  unless  money is  appropriated  for such purpose on a
yearly basis. Although  "non-appropriation" lease obligations are secured by the
leased property,  disposition of the property in the event of foreclosure  might
prove difficult.

LIQUIDITY DETERMINATIONS

The Board of Trustees has  established  guidelines  pursuant to which  Municipal
Lease Obligations,  Section 4(2) Commercial Paper and 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
restriction applicable to

                                        5

<PAGE>

investments in illiquid  securities.  In determining  the liquidity of Municipal
Lease Obligations,  Section 4(2) Commercial Paper and Rule 144A Securities,  the
Manager will consider the following  factors,  among others,  established by the
Board of Trustees:  (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.  Additional factors considered
by the Manager in determining the liquidity of a municipal lease obligation are:
(1)  whether  the  lease  obligation  is of a size that  will be  attractive  to
institutional   investors,   (2)  whether  the  lease   obligation   contains  a
non-appropriation  clause and the likelihood  that the obligor will fail to make
an  appropriation  therefor,  and (3) such  other  factors  as the  Manager  may
determine to be relevant to such determination.  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  Trustees  and will not be  considered
"restricted securities" for purposes of a Fund's investment restriction.

CALCULATION OF MATURITY FOR FIXED INCOME SECURITIES

A fixed income  security's  maturity is typically  determined  on a stated final
maturity basis, although there are some exceptions to the rule.

      If the  issuer  of the  security  has  committed  to take  advantage  of a
maturity shortening device, such as a call, refunding,  or redemption provision,
the date on which the instrument will be called,  refunded,  or redeemed will be
considered to be its maturity date.  Maturities of securities subject to sinking
fund arrangements are determined on a weighted average life basis,  which is the
average time for  principal to be repaid.  The weighted  average  lives of these
securities will be shorter than their stated final  maturities.  A security will
be treated as having a maturity  earlier  than its stated  maturity  date if the
security has technical  features,  such as a put or demand feature which, in the
judgment of the Manager,  will result in the security being valued in the market
as though it has the earlier maturity.

LENDING OF SECURITIES

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

      No loan of securities will be made if, as a result,  the aggregate of such
loans would exceed 33 1/3% of the value of a Fund's total assets.  The Trust may
terminate such loans at any time.

FORWARD CURRENCY CONTRACTS

Each Fund,  except the Growth and Tax Strategy,  GNMA and Treasury  Money Market
Trusts,  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.

      The  Funds  may  enter  into   forward   currency   contracts   under  two
circumstances.  First,  when a 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, a 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 a 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. A Fund may not hedge with respect to a
particular currency for an amount greater than the aggregate market value

                                        6

<PAGE>

(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 the Funds 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 Funds 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 the Funds are  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 Funds are obligated to deliver. The Funds are not required to enter
into such  transactions  and will not do so  unless  deemed  appropriate  by the
Manager.

      Although the Funds value their  assets each  business day in terms of U.S.
dollars,  they do not  intend to  convert  their  foreign  currencies  into U.S.
dollars on a daily basis.  They 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.

WHEN-ISSUED SECURITIES

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

      Debt securities purchased on a when-issued basis are subject to changes in
value in the same way that other debt securities  held in the Funds'  portfolios
are; that is, both generally experience appreciation when interest rates decline
and  depreciation  when interest rates rise. The value of such  securities  will
also be affected  by the  public's  perception  of the  creditworthiness  of the
issuer  and  anticipated  changes  in the level of  interest  rates.  Purchasing
securities on a when-issued  basis involves a risk that the yields  available in
the market  when the  delivery  takes  place may  actually  be higher than those
obtained in the transaction itself. Cash or high-quality, liquid-debt securities
equal to the amount of the when-issued  commitments are segregated at the Fund's
custodian  bank.  The  segregated  securities  are valued at  market,  and daily
adjustments are made to keep the value of the cash and segregated  securities at
least equal to the amount of such commitments by the Fund.

      On the settlement date of the when-issued  securities,  the Fund will meet
its obligations from then available cash, sale of segregated securities, sale of
other securities,  or from sale of the when-issued  securities themselves (which
may have a value greater or less than the Trust's payment obligations).  Sale of
securities to meet such obligations  carries with it a greater potential for the
realization of capital gains.

INVESTMENTS IN REAL ESTATE INVESTMENT TRUSTS (REITS)

Because the Income Strategy,  Balanced Strategy,  Cornerstone  Strategy,  Growth
Strategy,  and World Growth Funds may invest a portion of their assets in REITs,
the  Funds  may  also  be  subject  to  certain  risks  associated  with  direct
investments  in REITs.  REITs may be  affected  by changes in the value of their
underlying  properties  and by defaults by  borrowers  or tenants.  Furthermore,
REITs are dependent upon specialized management skills of their managers and may
have  limited  geographic  diversification,  thereby,  subjecting  them to risks
inherent in financing a limited  number of projects.  REITs depend  generally on
their ability to generate cash flow to make  distributions to shareholders,  and
certain REITs have  self-liquidation  provisions by which  mortgages held may be
paid in full and distributions of capital returns may be made at any time.

PUT AND CALL OPTIONS, FINANCIAL FUTURES CONTRACTS, OPTIONS ON FINANCIAL FUTURES
CONTRACTS

Although the GNMA Trust,  Income Strategy,  Balanced Strategy,  Growth Strategy,
and  Emerging  Funds are  permitted  to  purchase  and sell these  contracts  or
options,  the Funds have no current intention of doing so in the coming year and
will not engage in such  transactions  without first notifying  shareholders and
supplying further information in each Fund's Prospectus.

                                        7

TAX-EXEMPT SECURITIES

Tax-exempt  securities  generally include debt obligations  issued by states and
their political subdivisions, and duly constituted authorities and corporations,
to obtain funds to construct,  repair, or improve various public facilities such
as airports, bridges, highways,  hospitals, housing, schools, streets, and water
and  sewer  works.  Tax-exempt  securities  may  also  be  issued  to  refinance
outstanding  obligations  as well  as to  obtain  funds  for  general  operating
expenses and for loans to other public institutions and facilities.

      The two principal  classifications  of tax-exempt  securities are "general
obligations" and "revenue" or "special tax" bonds.  General obligation bonds are
secured by the  issuer's  pledge of its full faith,  credit and taxing power for
the payment of principal and interest.  Revenue or special tax bonds are payable
only from the revenues derived from a particular facility or class of facilities
or, in some cases,  from the proceeds of a special  excise or other tax, but not
from  general  tax  revenues.  The Funds may also invest in  tax-exempt  private
activity bonds,  which in most cases are revenue bonds and generally do not have
the  pledge of the  credit of the  issuer.  The  payment  of the  principal  and
interest on such industrial  revenue bonds is dependent solely on the ability of
the  user  of the  facilities  financed  by the  bonds  to  meet  its  financial
obligations and the pledge, if any, of real and personal property so financed as
security for such payment.  There are, of course,  many  variations in the terms
of, and the security underlying tax-exempt  securities.  Short-term  obligations
issued by states,  cities,  municipalities  or municipal  agencies,  include Tax
Anticipation  Notes,   Revenue  Anticipation  Notes,  Bond  Anticipation  Notes,
Construction Loan Notes, and Short-Term Discount Notes.

      The yields of tax-exempt securities depend on, among other things, general
money market conditions, conditions of the tax-exempt bond market, the size of a
particular  offering,  the  maturity  of the  obligation,  and the rating of the
issue. The ratings of Moody's  Investors  Service,  Inc.  (Moody's),  Standard &
Poor's Ratings Group (S&P),  Fitch Investors Service,  Inc. (Fitch),  and Duff &
Phelps Inc.  represent their opinions of the quality of the securities  rated by
them, see APPENDIX A. It should be emphasized  that such ratings are general and
are not absolute  standards of quality.  Consequently,  securities with the same
maturity,  coupon, and rating may have different yields, while securities of the
same maturity and coupon but with different  ratings may have the same yield. It
will  be the  responsibility  of  the  Manager  to  appraise  independently  the
fundamental quality of the tax-exempt securities included in a Fund's portfolio.
    

                           SPECIAL RISK CONSIDERATIONS

CURRENCY EXCHANGE RATE FLUCTUATIONS

The Income Strategy,  Balanced Strategy,  Cornerstone Strategy, Growth Strategy,
Emerging  Markets,  Gold,  International,  and World Growth Funds' assets may be
invested in securities of foreign issuers.  Any such investments will be made in
compliance  with U.S.  and foreign  currency  restrictions,  tax laws,  and laws
limiting  the  amount and types of  foreign  investments.  Pursuit of the Funds'
investment  objectives  will  involve  currencies  of the  United  States and of
foreign   countries.   Consequently,   changes  in  exchange   rates,   currency
convertibility,  and repatriation requirements may favorably or adversely affect
the Funds.

UNPREDICTABLE POLITICAL, ECONOMIC AND SOCIAL CONDITIONS

For  the  Income  Strategy,  Balanced  Strategy,  Cornerstone  Strategy,  Growth
Strategy,  Emerging  Markets,  Gold,  International,  and  World  Growth  Funds,
investing in  securities  of foreign  issuers  presents  certain other risks not
present in domestic investments,  including different accounting, reporting, and
disclosure  requirements  for  foreign  issuers,  possible  political  or social
instability,  including  policies of foreign  governments which may affect their
respective  equity  markets,   and  foreign  taxation   requirements   including
withholding taxes.

                             INVESTMENT RESTRICTIONS

The following investment restrictions have been adopted by the Trust for and are
applicable to each Fund as stated. 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  that  Fund's  outstanding   voting  securities.   The  investment
restrictions  of one Fund may thus be  changed  without  affecting  those of any
other Fund.

      Under the restrictions,  each of the Growth and Tax Strategy,  Cornerstone
Strategy, Gold, International, and World Growth Funds 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
      Investment  Company Act of 1940,  as amended  (1940 Act)) if, as a result,
      the Fund would own more than 10% of the outstanding  voting  securities of
      such  issuer or the Fund would have more than 5% of the value of its total
      assets invested in the securities of such issuer.

                                        8

<PAGE>

 (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)  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.

 (4)  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.

 (5)  Purchase securities on margin or sell securities short, except that it may
      obtain such  short-term  credits as are  necessary  for the  clearance  of
      securities transactions.

 (6)  Invest in put, call, straddle,  or spread options or interests in oil, gas
      or other mineral exploration or development  programs,  except that it may
      purchase  securities of issuers whose principal  business  activities fall
      within  such  areas in  accordance  with  its  investment  objectives  and
      policies.

 (7)  Invest more than 2% of the market value of its total assets in  marketable
      warrants  to  purchase  common  stock.   Warrants  initially  attached  to
      securities and acquired by a Fund upon original  issuance thereof shall be
      deemed to be without value.

 (8)  Purchase or sell real estate or partnership interests therein, except that
      the  Cornerstone  Strategy  Fund may purchase  securities  secured by real
      estate  interests  or  interests  therein,   or  issued  by  companies  or
      investment trusts which invest in real estate or interests therein.

 (9)  Purchase or sell commodities or commodity contracts.

(10)  Purchase securities of other open-end investment companies,  except a Fund
      may  invest  up to 10% of the  market  value of its  total  assets in such
      securities  through  purchases in the open market involving only customary
      broker's  commissions  or in  connection  with  a  merger,  consolidation,
      reorganization, or acquisition of assets approved by the shareholders.

(11)  Invest  more  than 5% of the  market  value  of its  total  assets  in any
      closed-end  investment  company  and  will not  hold  more  than 3% of the
      outstanding voting stock of any closed-end investment company.

(12)  Change  the  nature of  its business  so as  to cease  to be an investment
      company.

(13)  Issue senior securities as defined in the 1940 Act, except as permitted by
      Section 18(f)(2) and rules thereunder.

      For purposes of  restriction  8 above,  interests in publicly  traded Real
Estate Investment Trusts (REITs) are not deemed to be real estate or partnership
interests therein.

Each of the GNMA and Treasury Money Market Trusts 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

      companies  that deal in real  estate  or are  engaged  in the real  estate
      business.
    

Each  of the  Income Strategy, Balanced  Strategy, and Growth Strategy Funds 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)  Concentrate its investments in any one industry  although it may invest up

With respect to each Fund's concentration policies as described above and in its
Prospectus,  the Manager uses industry  classifications  for industries based on
categories established by Standard & Poor's Corporation (S&P) for the Standard &
Poor's 500 Composite Index, with certain modifications.  Because the Manager has
determined that certain categories within, or in addition to, those set forth by
S&P have unique investment  characteristics,  additional industries are included
as industry  classifications.  The Manager classifies  municipal  obligations by
projects with similar characteristics,  such as toll road revenue bonds, housing
revenue bonds or higher  education  revenue bonds. In addition,  the Cornerstone
Strategy Fund may not concentrate  investments in any one industry,  although it
may invest up to 25% of the value of its total assets in one industry; the Basic
Value  Stocks,   Foreign  Stocks,  and  U.S.  Government  Securities  investment
categories are not considered industries for this purpose.

ADDITIONAL RESTRICTION

   
The following  restriction is not  considered to be a fundamental  policy of the
Funds.  The Trust's  Board of Trustees  may change this  additional  restriction
without notice to or approval by the shareholders.

      Under the additional restriction, each of the Funds may not:

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

                             PORTFOLIO TRANSACTIONS

The Manager,  pursuant to the Advisory  Agreement  dated September 21, 1990, and
subject to the general  control of the  Trust's  Board of  Trustees,  places all
orders for the purchase  and sale of Fund  securities.  In  executing  portfolio
transactions and selecting brokers and dealers, it is the Trust's policy to seek
the best 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 used to purchase  securities for
the Income Strategy,  Growth and Tax Strategy,  Balanced  Strategy,  Cornerstone
Strategy,  Growth Strategy,  Emerging Markets,  Gold,  International,  and World
Growth  Funds,  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 a broker a higher
commission  than may be  charged by other  brokers,  provided  that the  Manager
determines  in good faith that such  commission is reasonable in relation to the
value of the brokerage and research services provided by such broker,  viewed in
terms of either that particular  transaction or of the overall responsibility of
the Manager to the Funds and its other clients. The Manager continuously reviews
the  performance  of  the   broker-dealers   with  whom  it  places  orders  for
transactions.   The  receipt  of  research  from   broker-dealers  that  execute
transactions  on behalf of the Trust 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 Trust.  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 Trust.  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 TRUST'S MANAGER.

      Securities of the same issuer may be purchased,  held, or sold at the same
time by the Trust for any or all of its Funds,  or other  accounts or  companies
for which the 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 Trust, 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 Trust
with those to be sold or purchased  for other  customers in order to obtain best
execution and lower brokerage commissions,  if any. In such event, allocation of
the  securities  so purchased or sold,  as well as the expenses  incurred in the
transaction,  will be made by the Manager in the manner it  considers to be most
equitable and consistent  with its fiduciary  obligations to all such customers,
including the Trust. In some instances,  this procedure may impact the price and
size of the position obtainable for the Trust.

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

   **  These amounts are 16.10%,  18.85%,  8.7%,  .83%,  4.59%,  .05%, and .43%,
       respectively, of brokerage fees paid by each Fund.

For the year ended May 31, 1997, 16.07%,  11.57%, 7.79%, 2.36%, 7.59%, .22%, and
1.58%, of the aggregate dollar amounts of transactions  involving the payment of
commissions by the Income Strategy, Growth and Tax Strategy,  Balanced Strategy,
Cornerstone Strategy, Growth Strategy, Emerging Markets, and World Growth Funds,
respectively, were effected through USAA Brokerage Services.

      The Manager  directed a portion of the Funds'  brokerage  transactions  to
certain broker-dealers that provided the Manager with research,  statistical and
other  information.   Such  transactions  amounted  to  $755,255,   $33,359,021,
$3,768,476, $65,579,532, $25,198,552, $283,516, $2,154,238, and $12,833,895, and
the related  brokerage  commissions  or  underwriting  commissions  were $1,154,
$46,750,  $5,267,  $87,403,  $46,990,  $850,  $2,850 and  $13,902 for the Income
Strategy,  Growth and Tax Strategy,  Balanced  Strategy,  Cornerstone  Strategy,
Growth  Strategy,  Emerging  Markets,  International  and  World  Growth  Funds,
respectively, for the year ended May 31, 1997.
    

PORTFOLIO TURNOVER RATES
   
The rate of  portfolio  turnover in any of the Funds  (other  than the  Treasury
Money Market Trust) will not be a limiting factor when the Manager deems changes
in a Fund's portfolio appropriate in view of its investment objective.  Although
no Fund will purchase or sell securities  solely to achieve  short-term  trading
profits,  a Fund may sell portfolio  securities  without regard to the length of
time held if consistent with the Fund's investment objective. A higher degree of
equity  portfolio  activity will increase  brokerage  costs to a Fund. It is not
anticipated that the portfolio turnover rates of the Income Strategy, Growth and
Tax Strategy, Balanced Strategy, Cornerstone Strategy, Growth Strategy, Emerging
Markets,  Gold,  International,  and World  Growth  Funds or the GNMA Trust will
exceed 100%.
    
      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 computer
the turnover rate.

                          FURTHER DESCRIPTION OF SHARES

The Trust is  authorized  to issue  shares of  beneficial  interest  in separate
portfolios.  Eleven such portfolios have been established which are described in
this SAI. Under the First Amended and Restated  Master Trust  Agreement  (Master
Trust  Agreement),  dated June 2, 1995,  as  amended,  the Board of  Trustees is
authorized  to create new  portfolios  in  addition  to those  already  existing
without the approval of the shareholders of the Trust. The Cornerstone  Strategy
and Gold  Funds  were  established  May 9, 1984,  by the Board of  Trustees  and
commenced public offering of their shares on August 15, 1984. The  International
Fund,  established on November 4, 1987,  commenced public offering of its shares
on July 11, 1988.  The Growth and Tax Strategy Fund was  established on November
3, 1988,  and  commenced  public  offering of its shares on January 11, 1989. On
November 7, 1990, the Board of Trustees  established the GNMA Trust and Treasury
Money Market Trust and commenced  public offering of their shares on February 1,
1991.  The World Growth Fund was  established  on July 21, 1992,  and  commenced
public offering of its shares on October 1, 1992. The Emerging  Markets Fund was
established on September 7, 1994, and commenced public offering of its shares on
November 7, 1994. The Income Strategy,  Balanced  Strategy,  and Growth Strategy
Funds were  established on June 2, 1995, and commenced  public offering of their
shares on September 1, 1995.

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

      Under the Trust's Master Trust Agreement,  no annual or regular meeting of
shareholders is required.  Thus, there will ordinarily be no shareholder meeting
unless otherwise required by the 1940 Act. Under certain circumstances, however,
shareholders  may apply to the Trustees for shareholder  information in order to
obtain signatures to request a shareholder  meeting.  Moreover,  pursuant to the
Master Trust Agreement,  any Trustee may be removed by the vote of two-thirds of
the  outstanding  Trust  shares and  holders  of 10% or more of the  outstanding
shares of the Trust can require  Trustees to call a meeting of shareholders  for
the  purpose  of voting on the  removal of one or more  Trustees.  On any matter
submitted to the  shareholders,  the holder of any share is entitled to one vote
per share (with proportionate voting for fractional shares) regardless

                                    13

of the  relative  net asset  values of the Funds'  shares.  However,  on matters
affecting an individual  Fund, a separate vote of the  shareholders of that Fund
is required.  For example, the Advisory Agreement must be approved separately by
each Fund and only becomes  effective  with respect to a Fund when a majority of
the outstanding  voting  securities of that Fund approves it.  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. For example,  a proposed  change
in the investment  objectives of a particular Fund would require the affirmative
vote of a majority of the outstanding voting securities of only that Fund.

      Shares  do  not  have  cumulative  voting  rights,  which  means  that  in
situations in which shareholders elect Trustees, holders of more than 50% of the
shares  voting  for the  election  of  Trustees  can elect  100% of the Board of
Trustees, and the holders of less than 50% of the shares voting for the election
of Trustees will not be able to elect any person as a Trustee.

      When issued,  each Fund's shares are fully paid and  nonassessable  by the
Trust, have no preemptive or subscription  rights,  and are fully  transferable.
There are no conversion rights.

                               TAX CONSIDERATIONS

TAXATION OF THE FUNDS

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,  a Fund must,  among other
things,  (1) derive in each  taxable  year at least 90% of its gross income from
dividends,  interest,  payments with respect to securities loans, gains from the
sale or other disposition of stock,  securities or foreign currencies,  or other
income  derived  with  respect  to its  business  of  investing  in such  stock,
securities,  or currencies (the 90% test);  (2) derive in each taxable year less
than 30% of its  gross  income  from the sale or other  disposition  of stock or
securities,  and certain options,  futures  contracts,  forward  contracts,  and
foreign  currencies  held for 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.  In the case of the Growth and Tax Strategy  Fund, in
order to be entitled to pay  exempt-interest  dividends to shareholders,  at the
close of each  quarter  of its  taxable  year,  at least 50% of the value of the
Fund's total assets must consist of obligations  the interest of which is exempt
from federal  income tax.  The Growth and Tax  Strategy  Fund intends to satisfy
this requirement.

      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
excise tax.

      The Income  Strategy,  Balanced  Strategy,  Cornerstone  Strategy,  Growth
Strategy, Emerging Markets, Gold, International, and World Growth Funds' ability
to make  certain  investments  may be  limited  by  provisions  of the Code that
require inclusion of certain unrealized gains or losses in the Fund's income for
purposes of the 90% test, the 30% test, and the distribution requirements of the
Code, and by provisions of the Code that characterize  certain income or loss as
ordinary  income or loss rather than  capital  gain or loss.  Such  recognition,
characterization  and timing rules  generally  apply to  investments  in certain
forward currency contracts,  foreign currencies and debt securities  denominated
in foreign currencies, as well as certain other investments.

      If the Income Strategy,  Balanced Strategy,  Cornerstone Strategy,  Growth
Strategy, Emerging Markets, Gold, International, or World Growth Funds invest in
an entity that is classified as a "passive  foreign  investment  company" (PFIC)
for federal income tax purposes,  the  application of certain  provisions of the
Code applying to PFICs could result in the imposition of certain  federal income
taxes on the Fund.  It is  anticipated  that any taxes on a Fund with respect to
investments in PFICs would be insignificant.

TAXATION OF THE SHAREHOLDERS

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 a 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 exchange that is less than or equal to the amount of
the  distribution  will be treated as long-term  capital  loss,  except as noted
below.

                                       14
<PAGE>


     In the case of the Growth and Tax Strategy Fund, if a shareholder  receives
an  exempt-interest  dividend  with respect to any share and such share has been
held for six months or less, any loss on the sale or exchange of such share will
be disallowed to the extent of such exempt-interest  dividend.  Shareholders who
are recipients of Social Security benefits should be aware that  exempt-interest
dividends received from the Growth and Tax Strategy Fund are includible in their
"modified  adjusted gross income" for purposes of determining the amount of such
Social  Security  benefits,  if any,  that are  required to be included in their
gross income.

      The Growth and Tax  Strategy  Fund may invest in private  activity  bonds.
Interest on certain  private  activity  bonds issued after August 7, 1986, is an
item of tax  preference  for  purposes  of the Federal  Alternative  Minimum Tax
(AMT),  although the interest  continues to be excludable  from gross income for
other purposes.  AMT is a supplemental tax designed to ensure that taxpayers pay
at least a minimum amount of tax on their income,  even if they make substantial
use of certain tax  deductions  and  exclusions  (referred to as tax  preference
items).  Interest from private activity bonds is one of the tax preference items
that is added to income  from other  sources  for the  purposes  of  determining
whether a taxpayer is subject to AMT and the amount of any tax to be paid.

      Opinions relating to the validity of the tax-exempt  securities  purchased
for the Growth and Tax Strategy Fund and the exemption of interest  thereon from
federal  income tax are  rendered by  recognized  bond  counsel to the  issuers.
Neither the  Manager's  nor the Fund's  counsel makes any review of the basis of
such opinions.

      The exemption of interest  income for federal income tax purposes does not
necessarily  result in exemption under the income or other tax laws of any state
or local taxing  authority.  Shareholders of a Fund may be exempt from state and
local  taxes  on  distributions  of  tax-exempt  interest  income  derived  from
obligations of the state and/or  municipalities of the state in which they are a
resident, but generally are subject to tax on income derived from obligations of
other  jurisdictions.  Shareholders  should consult their tax advisers about the
status of distributions from a Fund in their own states and localities.

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

(b)  At May 31, 1997,  the USAA  Family  of  Funds  consisted of four registered

     in the USAA Family of Funds.  In  addition,  Michael  J.C.  Roth  presently
     serves as a Trustee of USAA Life Investment Trust, a registered  investment
     company advised by IMCO,  consisting of seven funds offered to investors in
     a fixed and variable annuity contract with USAA Life Insurance Company. Mr.
     Roth receives no compensation as Trustee of USAA Life Investment Trust.

      All of the above Trustees are also  Trustees/Directors  of the other funds
for which IMCO serves as investment adviser. No compensation is paid by any fund
to any Trustee/Director  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 Trust also reimburses certain expenses of the Trustees who are not
affiliated  with the investment  adviser.  As of June 30, 1997, the officers and
Trustees of the Trust and their  families as a group  owned  beneficially  or of
record less than 1% of the outstanding shares of the Trust.

      As of June 30, 1997, USAA and its affiliates  owned 502,387 shares (37.7%)
of the Income  Strategy Fund,  419,450  shares (14.6%) of the Balanced  Strategy
Fund,  5,153,800 shares (43.6%) of the Emerging  Markets Fund,  6,111,511 shares
(20.9%) of the of the  International  Fund,  395,221  shares  (1.3%) of the GNMA
Trust and no shares of the Growth and Tax Strategy  Fund,  Cornerstone  Strategy
Fund,  Growth  Strategy Fund,  Gold Fund,  World Growth Fund, and Treasury Money
Market Trust.

      The Trust  knows of no other  persons  who, as of June 30,  1997,  held of
record  or owned  beneficially  5% or more of the  voting  stock  of any  Fund's
shares.
    

                               THE TRUST'S MANAGER

As described in each Fund's  Prospectus,  USAA Investment  Management Company is
the Manager and  investment  adviser,  providing the services under the Advisory
Agreement. The Manager,  organized in May 1970, has served as investment adviser
and underwriter for USAA Investment Trust from its inception.

   
      In addition  to  managing  the  Trust's  assets,  the Manager  advises and
manages the investments  for USAA and its affiliated  companies as well as those
of USAA Mutual Fund,  Inc.,  USAA Tax Exempt  Fund,  Inc.,  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  $____  billion,  of which
approximately $____ 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 Trustees
of the  Trust,  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 Trust.  The
Manager compensates all personnel,  officers,  and Trustees of the Trust if such
persons are also employees of the Manager or its affiliates.  For these services
under the  Advisory  Agreement,  each Fund has  agreed to pay the  Manager a fee
computed as described  under  MANAGEMENT  OF THE TRUST in its  Prospectus  (FUND
MANAGEMENT in the Growth and Tax Strategy Fund Prospectus).  Management fees are
computed and accrued daily and are payable monthly.
    

      Except for the services and facilities provided by the Manager,  the Funds
pay all other  expenses  incurred in their  operations.  Expenses  for which the
Funds are responsible include taxes (if any), brokerage commissions on portfolio
transactions, 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  Trustees  who are not  interested  (not  affiliated)
persons  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 Fund as
long as it is approved at least  annually  by a vote of the  outstanding  voting
securities of such Fund (as defined by the 1940 Act) or by the Board of Trustees
(on  behalf of such  Fund)  including  a majority  of the  Trustees  who are not
interested  persons of the Manager or (otherwise than as Trustees) of the Trust,
at a meeting  called for the purpose of voting on such  approval.  The  Advisory
Agreement may be terminated at any time by either the Trust or the Manager on 60
days'  written  notice.  It will  automatically  terminate  in the  event of its
assignment (as defined by the 1940 Act).

From time to time the Manager may, without prior notice to  shareholders,  waive
all or any portion of fees or agree to  reimburse  expenses  incurred by a Fund.
The Manager has  voluntarily  agreed to continue to limit the annual expenses of
the Treasury  Money  Market Trust to .375% and the Income  Strategy and Balanced
Strategy  Funds to 1.00% and 1.25%,  respectively,  of its ANA until  October 1,
1998,  and  will  reimburse  the  

                                       18

Funds for all expenses in excess of such limitation.  After October 1, 1998, any
such  waiver or  reimbursement  may be  terminated  by the  Manager  at any time
without prior notice to the shareholders.
    
For the last three fiscal years, management fees were as follows:

                         CALCULATION OF PERFORMANCE DATA

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

YIELD - TREASURY MONEY MARKET TRUST

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

      The calculation includes (1) the value of additional shares purchased with
dividends on the original  share,  and  dividends  declared on both the original
share  and  any  such  additional  shares,  and  (2)  any  fees  charged  to all
shareholder  accounts,  in  proportion  to the length of the base period and the
Trust's average account size.

      The capital changes  excluded from the  calculation  are realized  capital
gains and losses from the sale of securities  and  unrealized  appreciation  and
depreciation.  The  Trust's  effective  (compounded)  yield will be  computed by
dividing the seven-day annualized yield as defined above by 365, adding 1 to the
quotient, raising the sum to the 365th power, and subtracting 1 from the result.

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

   
              Yield For 7-day Period ended 5/31/97 . . . . . 5.10%
         Effective Yield For 7-day Period ended 5/31/97 . . . . . 5.23%
    

YIELD - INCOME STRATEGY FUND, GROWTH AND TAX STRATEGY FUND AND GNMA TRUST

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

          YIELD = 2 left [ left ({a-b} over cd + 1 right)^6 - 1 right]

   Where:     a  =  dividends and interest earned during the period
              b  =  expenses accrued for the period (net of reimbursement)
              c  =  the average  daily number of  shares outstanding  during the
                    period that were entitled to receive dividends
              d  =  the  maximum offering price per share on the last day of the
                    period

   
The 30-day  yields for the period  ended May 31, 1997,  for the Income  Strategy
Fund,  Growth and Tax Strategy Fund and GNMA Trust were 5.00%,  3.66% and 6.89%,
respectively.
    

TAX EQUIVALENT YIELD

A  tax-exempt  mutual  fund may  provide  more  "take-home"  income than a fully
taxable  mutual fund after paying taxes.  Calculating a "tax  equivalent  yield"
means converting a tax-exempt yield to a pretax  equivalent so that a meaningful
comparison  can be made between a tax-exempt  municipal fund and a fully taxable
fund. Because the Growth and Tax Strategy Fund invests a significant  percentage
of its assets in tax-exempt securities, it may advertise performance in terms of
a 30-day tax equivalent yield.

      To calculate a tax  equivalent  yield,  an investor  must know his federal
marginal  income  tax rate.  The tax  equivalent  yield for the  Growth  and Tax
Strategy  Fund is then  computed by dividing  that portion of the yield which is
tax-exempt  by the  complement  of the federal  marginal tax rate and adding the
product to that  portion of the yield  which is  taxable.  The  complement,  for
example,   of  a  federal  marginal  tax  rate  of  36.0%  is  64.0%,   that  is
(1.00-0.36=0.64).

                                       20

<PAGE>

                      Tax Equivalent Yield = (% Tax Exempt
             Income x 30-day Yield/ (1-Federal Marginal Tax Rate))
                       + (% Taxable Income x 30-day Yield)

   
      Based on a federal  marginal tax rate of 36.0%,  the tax equivalent  yield
for the Growth and Tax  Strategy  Fund for the period  ended May 31,  1997,  was
5.06%.
    

TOTAL RETURN

The Funds may advertise  performance in terms of average annual total return for
1-, 5-, and 10-year  periods,  or for such  lesser  periods as any of such Funds
have been in existence.  Average  annual total return is computed by finding the
average annual compounded rates of return over the periods that would equate the
initial  amount  invested  to the  ending  redeemable  value,  according  to the
following formula:

                                 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 such 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:
    

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.

                                       21

<PAGE>

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.

NOTE:  THOSE BONDS IN THE AA, A, AND BAA GROUPS WHICH MOODY'S  BELIEVES  POSSESS
THE STRONGEST  INVESTMENT  ATTRIBUTES ARE DESIGNATED BY THE SYMBOLS AA1, A1, AND
BAA1.

A description of ratings Ba and below assigned to debt obligations by Moody's is
included in Appendix A of the Emerging Markets Fund Prospectus.

   
S&P:
    

AAA      Debt rated AAA has the highest rating assigned by S&P.  Capacity to pay
         interest and repay principal is extremely strong.

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

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

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

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

A description  of ratings BB and below  assigned to debt  obligations  by S&P is
included in Appendix A of the Emerging Markets Fund Prospectus.

   
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 (+) AND 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:
    

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
AA       may vary slightly from time to time because of economic conditions.
AA-

                                       22

<PAGE>

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

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

   
2.   SHORT-TERM DEBT RATINGS

MOODY'S CORPORATE AND GOVERNMENT:

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

  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,  will be more  subject  to  variation.  Capitalization
            characteristics,  while still  appropriate,  may be more affected by
            external conditions. Ample 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 CORPORATE AND GOVERNMENT:
    

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

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.

   
S&P MUNICIPAL:
    

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

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

   
FITCH:
    

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 of timely  payment only  slightly  less in degree than issues
         rated F-1+.

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


                                       23

<PAGE>

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:

   
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 issue as to
         investment   grade.  Risk  factors  are  larger  and  subject  to  more
         variation. Nevertheless, timely payment is expected.

                       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.

                         HOW DOLLAR-COST AVERAGING WORKS

Item 27.      INDEMNIFICATION

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

        (a)   THE DIRECTOR AND OFFICER LIABILITY POLICY.  This policy covers all
              -----------------------------------------  losses  incurred by the
              Registrant,  its adviser and its  underwriter  from any claim made
              against those  entities or persons during the policy period by any
              shareholder  or  former  shareholder  of any Fund by reason of any
              alleged  negligent act, error or omission  committed in connection
              with the  administration  of the investments of said Registrant or
              in connection with the sale or redemption of shares issued by said
              Registrant.  The  Trust  will  not pay for such  insurance  to the
              extent that payment  therefor is in  violation  of the  Investment
              Company Act of 1940 or the Securities Act of 1933.

        (b)   INDEMNIFICATION  PROVISIONS  UNDER  AGREEMENT AND  DECLARATION  OF
              TRUST.
              ------------------------------------------------------------------
              Under Article VI of the Registrant's  Agreement and Declaration of
              Trust,  each of its trustees and officers or any person serving at
              the  Registrant's  request  as a  director,  officer or trustee of
              another  entity  in which the  Registrant  has any  interest  as a
              shareholder,  creditor or otherwise  ("Covered  Person")  shall be
              indemnified against all liabilities,  including but not limited to
              amounts paid in  satisfaction  of  judgments,  in compromise or as
              fines  and   penalties,   and   expenses,   including   reasonable
              accountants'  and counsel fees,  incurred by any Covered Person in
              connection with the defense or disposition of any action,  suit or
              other proceeding,  whether civil or criminal,  before any court or
              administrative or legislative body, in which such person may be or
              may have been threatened, while in office or thereafter, by reason
              of being or having  been such an  officer,  director  or  trustee,
              except  with  respect  to any  matter  as to  which  it  has  been
              determined that such Covered Person (i) did not act in good

                                       C-4

<PAGE>

              faith in the reasonable  belief that such Covered  Person's action
              was in or not opposed to the best  interests  of the Trust or (ii)
              had acted with willful misfeasance, bad faith, gross negligence or
              reckless  disregard of the duties  involved in the conduct of such
              Covered Person's office (either and both of the conduct  described
              in  (i)  and  (ii)  being  referred  to  hereafter  as  "Disabling
              Conduct").  A determination that the Covered Person is entitled to
              indemnification  may be made by (i) a final decision on the merits
              by a court or other body  before whom the  proceeding  was brought
              that the  person  to be  indemnified  was not  liable by reason of
              Disabling  Conduct,  (ii)  dismissal  of  a  court  action  or  an
              administrative   proceeding   against   a   Covered   Person   for
              insufficiency  of  evidence  of  Disabling  Conduct,  or  (iii)  a
              reasonable  determination,  based upon a review of the facts, that
              the  indemnitee  was not liable by reason of Disabling  Conduct by
              (a) a vote of a majority of a quorum of  trustees  who are neither
              "interested  persons"  of the  Registrant  as  defined  in section
              2(a)(19) of the 1940 Act nor parties to the proceeding,  or (b) an
              independent legal counsel in a written opinion.

              Expenses,  including  accountants  and counsel fees so incurred by
              any  such   Covered   Person  (but   excluding   amounts  paid  in
              satisfaction   of   judgments,   in  compromise  or  as  fines  or
              penalties),  may be paid  from  time  to  time by the  Fund of the
              Registrant in question in advance of the final  disposition of any
              such action, suit or proceeding,  provided that the covered person
              shall have  undertaken to repay the amounts so paid to the Fund of
              Registrant  in  question  if  it  is  ultimately  determined  that
              indemnification  of such expenses is not authorized  under Article
              VI of the Agreement and  Declaration  of Trust and (i) the Covered
              Person shall have provided security for such undertaking, (ii) the
              Registrant  shall be insured  against  losses arising by reason of
              any  lawful  advances,  or (iii) a  majority  of a  quorum  of the
              disinterested  trustees who are not a party to the proceeding,  or
              an  independent  legal  counsel in a written  opinion,  shall have
              determined,  based on a review  of  readily  available  facts  (as
              opposed  to full  trial-type  inquiry),  that  there is  reason to
              believe that the Covered Person  ultimately will be found entitled
              to  indemnification.  As to any matter disposed of by a compromise
              payment by any such Covered Person pursuant to a consent decree or
              otherwise,  no such indemnification either for said payment or for
              any other expenses shall be provided  unless such  indemnification
              shall be approved (a) by a majority of the disinterested  trustees
              of the  Registrant who are not a party to the proceeding or (b) by
              an independent legal counsel in a written opinion. Approval by the
              trustees  pursuant to clause (a) or by  independent  legal counsel
              pursuant  to clause (b) shall not prevent  the  recovery  form any
              Covered  Person  of any  amount  paid to such  Covered  Person  in
              accordance  with any of such  clauses as  indemnification  if such
              Covered Person is subsequently adjudicated by a court of competent
              jurisdiction  not to have  acted in good  faith in the  reasonable
              belief that such Covered  Person's action was in or not opposed to
              the best interests of the Registrant or to have been liable to the
              Registrant or its  shareholders by reason of willful  misfeasance,
              bad faith,  gross  negligence or reckless  disregard of the duties
              involved in the conduct of such Covered Person's office.

              Insofar  as  indemnification  for  liabilities  arising  under the
              Securities Act of 1933 may be permitted to trustees,  officers and
              controlling persons of the Registrant pursuant to the Registrant's
              Agreement  and   Declaration  of  the  Trust  or  otherwise,   the
              Registrant has been advised that, in the opinion of the Securities
              and Exchange Commission, such

                                       C-5

<PAGE>

              indemnification  is against  public policy as expressed in the Act
              and is,  therefore,  unenforceable.  In the event that a claim for
              indemnification  against such liabilities  (other than the payment
              by the  Registrant  of  expenses  incurred  or paid by a  trustee,
              officer or controlling  person of the Registrant in the successful
              defense of any  action,  suit or  proceeding)  is asserted by such
              trustee,  officer or  controlling  person in  connection  with the
              securities being  registered,  then the Registrant will, unless in
              the  opinion  of its  counsel  the  matter  has been  settled by a
              controlling   precedent,   submit   to  a  court  of   appropriate
              jurisdiction  the  question  of whether  indemnification  by it is
              against public policy as expressed in the Act and will be governed
              by the final adjudication of such issue.

January 14, 1997


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

Attention: Michael J.C. Roth, President

Gentlemen:

This  Facility  Agreement  Letter  (this  "Agreement")  sets forth the terms and
conditions  for loans (each a "Loan" and  collectively  the "Loans")  which USAA
Capital  Corporation  ("CAPCO")  may from time to time make  during  the  period
commencing  January 14, 1997 and ending January 13, 1998 (the "Facility Period")
to USAA Mutual Fund,  Inc., USAA Investment  Trust,  USAA Tax Exempt Fund, Inc.,
and USAA State Tax-Free Trust,  and each  investment  company which may become a
party hereto  pursuant to the terms of this  Agreement  (each a  "Borrower"  and
collectively  the  "Borrowers"),  each of which is executing  this  Agreement on
behalf  of and for the  benefit  of the  series  of funds  comprising  each such
Borrower as set forth on Schedule A hereto (as hereafter  modified or amended in
accordance with the terms hereof) (each a "Fund" and  collectively the "Funds"),
under a master  revolving  credit  facility (the  "Facility").  USAA  Investment
Management  Company is the Manager  and  Investment  Advisor of each Fund.  This
Agreement  replaces in its entirety that certain Facility Agreement Letter dated
January 15,  1996,  between the  Borrowers  and CAPCO.  CAPCO and the  Borrowers
hereby agree as follows:

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

         2. Purpose and  Limitations on  Borrowings.  Each Borrower will use the
proceeds of each Loan made to it solely for  temporary or emergency  purposes of
the Fund for whose  benefit  it is  borrowing  in  accordance  with such  Fund's
Borrowing  Limit (Schedule A) and prospectus in
<PAGE>

effect at the time of such Loan.  Portfolio securities may not be purchased by a
Fund while there is a Loan outstanding under the Facility or any other facility,
if the  aggregate  amount of such Loan and any other such loan exceeds 5% of the
total assets of such Fund.

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

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

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

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

<PAGE>

         7. Mandatory Termination of the Facility. The Facility, unless extended
by  written  amendment,  shall  automatically  terminate  on the last day of the
Facility Period and any Loans then  outstanding  (together with accrued interest
thereon and any other amounts owing  hereunder) shall be due and payable on such
date.
         8. Uncommitted Facility. The Borrowers acknowledge that the Facility is
an uncommitted facility and that CAPCO shall have no obligation to make any Loan
requested during the Facility Period under this Agreement.  Further, CAPCO shall
not make any Loan if this Facility has been  terminated by the Borrowers,  or if
at the time of a request for a Loan by a Borrower  (on behalf of the  applicable
Fund(s)) there exists any Event of Default or condition which,  with the passage
of time or giving of notice,  or both,  would  constitute  or become an Event of
Default with respect to such Borrower (or such applicable Fund(s)).

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

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

         10.      Confirmations; Crediting  of Funds;  Reliance  by CAPCO.  Upon
receipt by CAPCO of a  Borrowing Notice:

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

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

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

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

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

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

                  (b) Financial Information;  Disclosure,  etc. The Borrower has

results of operations of such Borrower and the applicable Funds on the dates and

administrative  orders of the Securities and Exchange Commission (the ASEC") and
applicable Blue Sky  authorities.  The Borrower and the applicable  Funds are in
compliance in all material respects with all of the provisions of the Investment
Company Act of 1940,  and such  Borrower has filed all reports with the SEC that
are required of it or the applicable Funds;

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

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

         13.  Affirmative  Covenants  of the  Borrowers.  Until such time as all
amounts of principal  and  interest  due to CAPCO by a Borrower  pursuant to any
Loan made to such Borrower 

<PAGE>

is irrevocably paid in full, and until the Facility is terminated, such Borrower
(for itself and on behalf of its respective Funds) agrees:

                  (a) To deliver to CAPCO as soon as  possible  and in any event
within  ninety (90) days after the end of each fiscal year of such  Borrower and
the  applicable  Funds,  Statements  of Assets and  Liabilities,  Statements  of
Operations and Statements of Changes in Net Assets of each  applicable  Fund for
such  fiscal  year,  as set forth in each  applicable  Fund's  Annual  Report to
shareholders  together  with a  calculation  of the  maximum  amount  which each
applicable  Fund could  borrow under its  Borrowing  Limit as of the end of such
fiscal year;

                  (b) To deliver to CAPCO as soon as available  and in any event
within  seventy-five  (75) days after the end of each semiannual  period of such
Borrower  and the  applicable  Funds,  Statements  of  Assets  and  Liabilities,
Statement  of  Operations  and  Statements  of  Changes  in Net  Assets  of each
applicable  Fund as of the end of such semiannual  period,  as set forth in each
applicable Fund's Semiannual Report to shareholders, together with a calculation
of the  maximum  amount  which  each  applicable  Fund  could  borrow  under its
Borrowing Limit at the end of such semiannual period;

                  (c) To deliver to CAPCO prompt notice of the occurrence of any
event or  condition  which  constitutes,  or is likely to result in, a change in
such  Borrower  or any  applicable  Fund which could  reasonably  be expected to
materially adversely affect the ability of any applicable Fund to promptly repay
outstanding  Loans made for its  benefit  or the  ability  of such  Borrower  to
perform its obligations under this Agreement or the Note;

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

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

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

<PAGE>

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

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

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

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

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

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

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

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

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

<PAGE>

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

                  (g) An event of default  shall occur and be  continuing  under
any other facility; then, in any event, and at any time thereafter, if any Event
of Default shall be  continuing,  CAPCO may by written  notice to the applicable
Borrower or Fund (i)  terminate  the Facility  with respect to such  Borrower or
Fund and (ii) declare the principal  and interest in respect of any  outstanding
Loans with respect to such Borrower or Fund, and all other amounts due hereunder
with  respect  to such  Borrower  or Fund,  to be  immediately  due and  payable
whereupon the  principal  and interest in respect  thereof and all other amounts
due  hereunder  shall  become  forthwith  due and payable  without  presentment,
demand,  protest or other notice of any kind, all of which are expressly  waived
by the Borrowers.

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

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

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

         17. Limited Recourse.  CAPCO agrees (i) that any claim,  liability,  or
obligation  arising  hereunder  or under  the Note  whether  on  account  of the
principal of any Loan,  interest  thereon,  or any other amount due hereunder or
thereunder  shall be  satisfied  only from the assets of the  specific  Fund for
whose benefit a Loan is borrowed and in any event in an amount not to exceed the
outstanding  principal  amount of any Loan  borrowed  for such  Fund's  benefit,
together with accrued and unpaid interest due and owing thereon, and such Fund's
share of any other amount due 

<PAGE>

hereunder and under the Note (as  determined in accordance  with the  provisions
hereof)  and (ii) that no assets of any fund shall be used to satisfy any claim,
liability, or obligation arising hereunder or under the Note with respect to the
outstanding  principal  amount of any Loan borrowed for the benefit of any other
Fund or any  accrued  and unpaid  interest  due and owing  thereon or such other
Fund's share of any other amount due hereunder and under the Note (as determined
in accordance with the provisions hereof).

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

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

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

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

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

         23.      Modifications.    No  provision of this  Agreement or the Note
may be waived, modified or discharged  except by mutual written agreement of all
parties.  THIS WRITTEN LOAN AGREEMENT AND THE NOTE REPRESENT THE FINAL AGREEMENT
BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,

<PAGE>

CONTEMPORANEOUS  OR SUBSEQUENT ORAL AGREEMENTS OF THE  PARTIES.  THERE ARE NO 
UNWRITTEN AGREEMENTS BETWEEN THE PARTIES.

         24.      Governing Law and Jurisdiction.    This  Agreement  shall  be 
governed  by  and  construed  in accordance with the laws of the state of Texas
without regard to the choice of law provisions thereof.

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

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

Sincerely,

USAA CAPITAL CORPORATION

                           MASTER GRID PROMISSORY NOTE


U.S. $750,000,000                                       Dated: January 14, 1997


         FOR VALUE  RECEIVED,  each of the  undersigned  (each a "Borrower"  and
collectively the "Borrowers"),  severally and not jointly,  on behalf of and for
the benefit of the series of funds  comprising  each such  Borrower as listed on
Schedule A to the Agreement as defined below (each a "Fund" and collectively the
"Funds")  promises to pay to the order of USAA Capital  Corporation  ("APCO") at
CAPCO's office located at 9800 Fredericksburg Road, San Antonio, Texas 78288, in
lawful money of the United States of America,  in immediately  available  funds,
the principal amount of all Loans made by CAPCO to such Borrower for the benefit
of the applicable  Funds under the Facility  Agreement  Letter dated January 14,
1997 (as amended or modified,  the "Agreement"),  among the Borrowers and CAPCO,
together with interest  thereon at the rate or rates set forth in the Agreement.
All payments of interest and principal  outstanding  shall be made in accordance
with the terms of the Agreement.

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

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

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

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

<PAGE>

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

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

         Loans under the Agreement and this Note are  subordinated to loans made
under  the  $100,000,000  364-day  committed  Mater  Revolving  Credit  Facility
Agreement  between the Borrowers and NationsBank of Texas,  N.A.  (NationsBank),
dated  January  15,  1997,  in the  manner  and to the  extent  set forth in the
Agreement among the Borrowers, CAPCO and NationsBank, dated January 15, 1997.

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

January 15, 1997

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


Attention:      Michael J.C. Roth, President

Gentlemen:

This  Facility  Agreement  Letter  (this  "Agreement")  sets forth the terms and
conditions  for  loans  (each a  "Loan"  and  collectively  the  "Loans")  which
NationsBank  of Texas,  N.A.  (the  "Bank")  agrees to make  during  the  period
commencing  January 15, 1997 and ending January 14, 1998 (the "Facility Period")
to USAA Mutual Fund,  Inc., USAA Investment  Trust,  USAA Tax Exempt Fund, Inc.,
and USAA State Tax-Free Trust,  and each  investment  company which may become a
party hereto  pursuant to the terms of this  Agreement  (each a  "Borrower"  and
collectively  the  "Borrowers"),  each of which is executing  this  Agreement on
behalf  of and for the  benefit  of the  series  of funds  comprising  each such
Borrower as set forth on Schedule A hereto (as hereafter  modified or amended in
accordance with the terms hereof) (each a "Fund" and  collectively the "Funds"),
under a master  revolving  credit  facility  (the  "Facility").  This  Agreement
replaces in its entirety that certain  Facility  Agreement  Letter dated January
16, 1996, as heretofore amended or modified, between the Borrowers and the Bank.
The Bank and the Borrowers hereby agree as follows:

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

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

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

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

<PAGE>

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

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

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

       5. Facility Fee. Beginning with the date of this Agreement and until such
time as all Loans have been irrevocably repaid to the Bank in full, and the Bank
is no longer obligated to make Loans, the Funds (to be allocated among the Funds
as the  Borrowers  deem  appropriate)  shall pay to the Bank a facility fee (the
"Facility  Fee") in the  amount of .05 of one  percent  (5 basis  points) of the
amount of the  Commitment,  as it may be  reduced  pursuant  to  section  6. The
Facility Fee shall be payable quarterly in arrears beginning March 31, 1997, and
upon termination of the Facility (whether by acceleration or otherwise).

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

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

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

<PAGE>

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

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

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

       10. Confirmations; Crediting of Funds; Reliance by the Bank. Upon receipt
by the Bank of a Borrowing Notice:
<PAGE>

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

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

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

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

       11.  Borrowing  Resolutions  and  Officers'  Certificates;  Subordination
Agreement.  Prior to the  making of any Loan  pursuant  to this  Agreement,  the
Borrowers  shall have  delivered  to the Bank (a) the duly  executed  Note,  (b)
resolutions of each Borrower's  Trustees or Board of Directors  authorizing such
Borrower to execute,  deliver and perform this  Agreement and the Note on behalf
of the applicable Funds, (c) an Officer's  Certificate in substantially the form
set  forth in  Exhibit  D to this  Agreement,  authorizing  certain  individuals
("Authorized Individuals"), to take on behalf of each Borrower (on behalf of the
applicable  Funds)  actions  contemplated  by this Agreement and the Note, (d) a
subordination agreement in substantially the form set forth in Exhibit E to this
Agreement, and (e) the opinion of counsel to USAA Investment Management Company,
manager and advisor to the  Borrowers,  with respect to such matters as the Bank
may reasonably request.
<PAGE>

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

                (a) Organization,  Standing,  etc. The Borrower is a corporation
       or trust duly  organized,  validly  existing,  and in good standing under
       applicable state laws and has all requisite  corporate or trust power and
       authority to carry on its  respective  businesses  as now  conducted  and
       proposed  to be  conducted,  to enter into this  Agreement  and all other
       documents  to be  executed  by it in  connection  with  the  transactions
       contemplated  hereby, to issue and borrow under the Note and to carry out
       the terms hereof and thereof;

                (b)  Financial  Information;  Disclosure,  etc. The Borrower has
       furnished  the Bank with certain  financial  statements  of such Borrower
       with  respect  to itself  and the  applicable  Funds,  all of which  such
       financial  statements  have been  prepared in accordance  with  generally
       accepted  accounting  principles applied on a consistent basis and fairly
       present the financial position and results of operations of such Borrower
       and the  applicable  Funds on the  dates and for the  periods  indicated.
       Neither this  Agreement  nor any financial  statements,  reports or other
       documents or  certificates  furnished to the Bank by such Borrower or the
       applicable Funds in connection with the transactions  contemplated hereby
       contain  any untrue  statement  of a  material  fact or omit to state any
       material  fact  necessary  to make the  statements  contained  herein  or
       therein in light of the circumstances when made not misleading;

                (c)  Authorization;   Compliance  with  Other  Instruments.  The
       execution,  delivery and  performance of this Agreement and the Note, and
       borrowings  hereunder,   have  been  duly  authorized  by  all  necessary
       corporate  or trust  action of the  Borrower  and will not  result in any
       violation of or be in conflict  with or  constitute  a default  under any
       term of the charter,  by-laws or trust  agreement of such Borrower or the
       applicable  Funds,  or of any  borrowing  restrictions  or  prospectus or
       statement of additional  information  of such Borrower or the  applicable
       Funds, or of any agreement, instrument, judgment, decree, order, statute,
       rule or governmental regulation applicable to such Borrower, or

<PAGE>

       result in the creation of any mortgage,  lien, charge or encumbrance upon
       any of the properties or assets of such Borrower or the applicable  Funds
       pursuant to any such term. The Borrower and the applicable  Funds are not
       in violation of any term of their  respective  charter,  by-laws or trust
       agreement,  and  such  Borrower  and  the  applicable  Funds  are  not in
       violation of any material  term of any  agreement or  instrument to which
       they are a party,  or to the best of such  Borrower's  knowledge,  of any
       judgment,   decree,  order,  statute,  rule  or  governmental  regulation
       applicable to them;

                (d) SEC Compliance. The Borrower and the applicable Funds are in
       compliance in all material respects with all federal and state securities
       or  similar  laws  and   regulations,   including  all  material   rules,
       regulations  and  administrative  orders of the  Securities  and Exchange
       Commission (the "SEC") and applicable Blue Sky authorities.  The Borrower
       and the applicable Funds are in compliance in all material  respects with
       all of the  provisions of the  Investment  Company Act of 1940,  and such
       Borrower  has filed all reports  with the SEC that are  required of it or
       the applicable Funds;

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

                (f) Borrowers'  Relationship  to Funds.  The assets of each Fund
       for whose  benefit  Loans are  borrowed by the  applicable  Borrower  are
       subject to and liable for such Loans and are available to the  applicable
       Borrower for the repayment of such Loans.

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


<PAGE>

                (a) To deliver to the Bank as soon as possible  and in any event
       within  ninety  (90)  days  after  the  end of each  fiscal  year of such
       Borrower and the applicable Funds,  Statements of Assets and Liabilities,
       Statements of Operations  and Statements of Changes in Net Assets of each
       applicable  Fund for such fiscal  year,  as set forth in each  applicable
       Fund's Annual Report to  shareholders  together with a calculation of the
       maximum  amount  which  each  applicable  Fund  could  borrow  under  its
       Borrowing Limit as of the end of such fiscal year;

                (b) To deliver to the Bank as soon as available and in any event
       within  seventy-five (75) days after the end of each semiannual period of
       such  Borrower  and  the  applicable  Funds,  Statements  of  Assets  and
       Liabilities,  Statements of Operations  and  Statements of Changes in Net
       Assets of each applicable  Fund as of the end of such semiannual  period,
       as set forth in each applicable Fund's Semiannual Report to shareholders,
       together with a calculation of the maximum  amount which each  applicable
       Fund could borrow under its Borrowing Limit at the end of such semiannual
       period;

                (c) To deliver to the Bank prompt  notice of the  occurrence  of
       any event or condition  which  constitutes,  or is likely to result in, a
       change in such Borrower or any applicable Fund which could  reasonably be
       expected to  materially  adversely  affect the ability of any  applicable
       Fund to  promptly  repay  outstanding  Loans made for its  benefit or the
       ability of such Borrower to perform its obligations  under this Agreement
       or the Note;

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

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

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

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

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

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

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

                (a) Any  Borrower  or  Fund  shall  default  in the  payment  of
       principal  or interest on any Loan or any other fee due  hereunder  for a

<PAGE>

       period of five (5) days after the same becomes due and  payable,  whether
       at maturity or with  respect to the  Facility Fee at a date fixed for the
       payment thereof;

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

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

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

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

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

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

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

<PAGE>

of any kind, all of which are expressly waived by the Borrowers.

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

                (a) Any investment  company that becomes part of the same "group
       of investment companies" (as that term is defined in Rule 11a-3 under the
       Investment  Company  Act of  1940)  as the  original  Borrowers  to  this
       Agreement, may, by submitting an amended Schedule A and Exhibit B to this
       Agreement  to the Bank  (which  amended  Schedule  A and  Exhibit B shall
       replace  the  Schedule  A and  Exhibit  B which  are  then a part of this
       Agreement) and such other  documents as the Bank may reasonably  request,
       become a party to this  Agreement and may become a "Borrower"  hereunder;
       and
                (b) A Borrower  may,  by  submitting  an amended  Schedule A and
       Exhibit B to this  Agreement  to the Bank (which  amended  Schedule A and
       Exhibit B shall  replace  the  Schedule A and  Exhibit B which are then a
       part of this  Agreement),  add  additional  Funds for whose  benefit such
       Borrower  may  borrow  Loans.  No such  amendment  of  Schedule A to this
       Agreement shall amend the Borrowing Limit  applicable to any Fund without
       the prior consent of the Bank.

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

Note (as determined in accordance with the provisions hereof).

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

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

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

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

<PAGE>

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

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

       24.  Increased  Cost and  Reduced  Return.  If at any time after the date
hereof,  the Bank  (which  shall  include,  for  purposes of this  Section,  any
corporation  controlling the Bank)  determines that the adoption or modification
of any applicable law regarding the Bank's  required  levels of reserves,  other
than the  reserve  requirement  taken into  account  when  computing  the London
Interbank  Offered  Rate as  provided  in Section 3, or capital  (including  any
allocation of capital requirements or conditions),  or similar requirements,  or
any  interpretation  or  administration   thereof  by  a  governmental  body  or
compliance  by the Bank  with any of such  requirements,  has or would  have the
effect of (a) increasing the Bank's costs relating to the Loans, or (b) reducing
the yield or rate of  return of the Bank on the  Loans,  to a level  below  that
which the Bank could have achieved but for the adoption or  modification  of any
such  requirements,  the Funds (to be allocated among the Funds as the Borrowers
deem  appropriate)  shall,  within fifteen (15) days of any request by the Bank,
pay to the Bank such additional  amounts as (in the Bank's sole judgment,  after
good  faith  and  reasonable  computation)  will  compensate  the  Bank for such
increase in costs or reduction in yield or rate of return of the Bank.  Whenever
the Bank shall seek compensation for any increase in costs or reduction in yield
or rate of return, the Bank shall provide a certificate as the Borrower(s) shall
reasonably request.  Failure by the Bank to demand payment within 90 days
<PAGE>

of any additional  amounts payable  hereunder  shall  constitute a waiver of the
Bank's right to demand payment of such amounts at any subsequent  time.  Nothing
herein contained shall be construed or so operate as to require the Borrowers or
the Funds to pay any interest,  fees, costs or charges greater than is permitted
by applicable law.

       25. Governing Law and Jurisdiction.  This Agreement shall be  governed by
and construed in accordance with the laws  of the state of  Texas without regard
to the choice of law provisions thereof.

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

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

Sincerely,

NATIONSBANK OF TEXAS, N.A.

collectively the "Borrowers"),  severally and not jointly,  on behalf of and for
the benefit of the series of funds  comprising  each such  Borrower as listed on
Schedule A to the Agreement as defined below (each a "Fund" and collectively the
"Funds") promises to pay to the order of NATIONSBANK OF TEXAS, N.A. (the "Bank")

in the Agreement.

         The  Bank is  authorized  to  endorse  the  particulars  of  each  Loan

it is borrowing) hereunder.

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

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

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

Name and Address of Creditor:
USAA Capital Corporation
9800 Fredericksburg Road
San Antonio, Texas  78288
                                   (Creditor)
- ---------------------------------------------

 1. Background.  Debtor is or may be indebted to Lender pursuant to that certain
    Facility  Agreement  Letter dated January 15, 1997 between Debtor and Lender
    ("Senior Facility Agreement"). Debtor also is or may be indebted to Creditor
    pursuant to that certain  Facility  Agreement  Letter dated January 14, 1997
    between Debtor and Creditor  ("Subordinated  Facility Agreement").  All debt
    (as hereinafter  defined) under the Senior Facility Agreement is hereinafter
    referred to as "senior debt" and all debt (as hereinafter defined) under the
    Subordinated  Facility Agreement is hereinafter referred to as "subordinated
    debt".

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

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

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

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

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

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

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

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

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

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

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