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

WHAT ARE EACH FUND'S INVESTMENT OBJECTIVES AND MAIN STRATEGIES?

Each Fund has a common investment objective of providing Florida investors with
a high level of current  interest  income  that is exempt from  federal  income
taxes and shares that are exempt from the Florida intangible  personal property
tax.  The  Florida  Tax-Free  Money  Market  Fund has a  further  objective  of
preserving capital and maintaining liquidity. Each Fund has separate investment
policies to achieve its objective.

The   FLORIDA   TAX-FREE   INCOME  FUND   invests   primarily   in   long-term,
investment-grade  Florida tax-exempt  securities.  The Fund's average portfolio
maturity is not restricted, but is expected to be greater than 10 years.

The  FLORIDA  TAX-FREE  MONEY  MARKET  FUND  invests  in  high-quality  Florida
tax-exempt securities with maturities of 397 days or less.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that these objectives will be achieved.  See FUND INVESTMENTS on page
9 for more information.

MAIN RISKS OF INVESTING IN THESE FUNDS

The two primary  risks of  investing  in these Funds are credit risk and market
risk. As with other mutual funds, losing money is an additional risk associated
with investing in these Funds.

o   CREDIT RISK  involves the  possibility  that a borrower  cannot make timely
    interest and principal payments on its securities.

o   MARKET  RISK  involves  the  possibility  that  the  value  of each  Fund's
    investments  will  decline  due to an increase  in  interest  rates,  or to
    adverse  changes in supply and demand for  municipal  securities,  or other
    market factors.

These  credit and market risks may be magnified because  each Fund concentrates
in Florida tax-exempt securities.

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

IF INTEREST RATES DECREASE:  the yield of each Fund may decrease and the market
value of the Florida Tax-Free Income Fund's securities may increase,

                                       2
<PAGE>

which would likely increase  the Fund's  net asset value and total return.  The
Florida Tax-Free Money Market Fund's total return may decrease.

As you consider an  investment  in any Fund,  you should also take into account
your tolerance for the daily  fluctuations of the financial markets and whether
you can afford to leave your money in this  investment for long periods of time
to ride out down periods.

An investment in either Fund is not a deposit of USAA Federal  Savings Bank and
is not insured or guaranteed by the Federal  Deposit  Insurance  Corporation or
any other  government  agency.  Although the Florida Tax-Free Money Market Fund
seeks to preserve the value of your  investment at $1 per share, it is possible
to lose money by investing in that Fund.

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

COULD THE VALUE OF YOUR INVESTMENT IN THESE FUNDS FLUCTUATE?

Yes, it could.  In fact, the value of your  investment in the Florida  Tax-Free
Income Fund likely will  increase or decrease.  However,  we manage the Florida
Tax-Free  Money Market Fund in accordance  with strict  Securities and Exchange
Commission guidelines designed to preserve the Fund's value at $1 per share.

The value of the securities in which the Florida  Tax-Free  Income Fund invests
typically  fluctuates  inversely  with changes in the general level of interest
rates.  Changes in the  creditworthiness of issuers and changes in other market
factors such as the  relative  supply of and demand for  tax-exempt  bonds also
create value  fluctuations.  The bar charts shown below  illustrate  the Funds'
volatility and performance from year to year over the life of the Funds.

All mutual funds must use the same formulas to calculate total return.

advertise total return. The 7-day yield quotation more closely reflects current
earnings of the Fund than the total return quotation.  The effective yield will
be slightly  higher  than the yield  because of the  compounding  effect of the
assumed  reinvestment.  Current yields and effective yields fluctuate daily and
will vary with  factors  such as  interest  rates  and the  quality,  length of
maturities,  and type of investments  in the portfolio.  The Fund's 7-day yield
for the period ended March 31, 1998, was 3.30%.

TAX EQUIVALENT YIELD

Investors use tax equivalent  yields to compare  taxable and  tax-exempt  fixed
income  investments  using a common yield measure.  The tax equivalent yield is
the  yield  that a fully  taxable  investment  must  generate  to earn the same
"take-home" yield as a tax-exempt investment. The calculation depends upon your
federal and Florida  Intangibles  Tax rates and  assumes  that an investor  can
fully  itemize  deductions  on his or her federal  tax return.  The higher your
marginal tax bracket,  the higher will be the tax equivalent yield and the more
valuable is the Fund's tax exemption.


For  example,  if you assume a federal  marginal  tax rate of 36% and a Florida 
Intangibles  Tax  Effect  of .12%,  the  Effective  Marginal  Tax Rate would be 
36.08%. Using this tax rate, the Funds'  tax  equivalent yields  for the period 
ending March 31, 1998, would be as follows:

Using the example,  to exceed the 30-day yield of the Florida  Tax-Free  Income
Fund on an  after-tax  basis,  you must find a fully  taxable  investment  that
yields  more than  7.43%.  Likewise,  to exceed the 7-day  yield of the Florida
Tax-Free  Money  Market Fund,  you must find a fully  taxable  investment  that
yields more than 5.16%.

FUND INVESTMENTS

Principal Investment Strategies and Risks

   Q What is each Funds' principal investment strategy?

   A We will attempt to achieve each Fund's objective by investing each  Fund's
     assets  primarily in  securities issued  by  the  State  of  Florida,  its
     political  subdivisions and  instrumentalities, and  by other governmental
     entities,  if,  in  the  opinion  of  counsel,  the  interest  from   such
     obligations  is excluded from gross income for federal income tax purposes
     and  the obligations  are exempt  from  the  Florida  intangible  personal
     property tax.

     These securities include municipal debt  obligations that have been issued
     by Florida and it's political subdivisions, and duly constituted state and
     local authorities and corporations. We refer to these securites as Florida
     tax-exempt securities.  Florida tax-exempt  securities  are issued to fund
     public  infrastructure projects  such as  streets and  highways,  schools,
     water and sewer  systems, hospitals, and airports. They 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.

     Because the projects  benefit the public,  Congress has granted  exemption
     from  federal  income  taxes for the  interest  income  arising from these
     securities.  Likewise,  the  Florida  Legislature has granted an exemption 
     from state intangible personal property  taxes  for most Florida municipal 
     securities.

   Q What  types of  tax-exempt  securities  will be  included  in each  Fund's
     portfolio?

   A Each  Fund's  assets may be invested  in any of the  following  tax-exempt
     securities:

     o general obligation bonds which are secured by the issuer's pledge of its
       full faith,  credit,  and taxing power for the payment of principal  and
       interest;

     o revenue  bonds  which  are  payable  from  the  revenue  derived  from a
       particular  facility  or class of  facilities  or, in some  cases,  from
       annual appropriations made by the state legislature for the repayment of
       interest and principal or other specific  revenue  source,  but not from
       the general taxing power;

                                       9
<PAGE>

     o lease obligations  backed by the  municipality's  covenant to budget for
       the payments due under the lease obligation; and

     o industrial  development  bonds   issued  by   or  on  behalf  of  public
       authorities to obtain funds for privately-operated facilities.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may invest up to 100% of each  Fund's  assets in
     short-term  securities  whether or not they are exempt from federal income
     tax and  Florida intangible  personal property taxes.  To the  extent that
     these temporary investments produce taxable income, that income may result
     in that Fund not fully achieving its investment objective.

   Q What are the principal  risks  associated  with  investments in tax-exempt
     securities?

   A The two principal  risks of investing in tax-exempt  securities are credit
     risk and market risk.

     [CAUTION LIGHT]
     CREDIT  RISK.  Credit  risk is the  possibility  that an issuer of a fixed
     income  security  will  fail  to  make  timely  payments  of  interest  or
     principal.  We attempt to minimize the Funds' credit risks by investing in
     securities  considered at least  investment grade at the time of purchase.
     Nevertheless,  even investment-grade securities are subject to some credit
     risk. In addition,  the ratings of securities  are estimates by the rating
     agencies of the credit quality of the securities. The ratings may not take
     into account  every risk that  interest or  principal  will be repaid on a
     timely basis.

     When evaluating  potential  investments  for the Funds,  our analysts also
     independently  assess credit risk and its impact on the Funds'  portfolio.
     Securities  in the lowest  investment  grade ratings  category  (BBB) have
     speculative grade characteristics. Changes in economic conditions or other
     circumstances  are more  likely to lead to a weakened  capability  to make
     principal and interest  payments on these  securities than is the case for
     higher-rated securities.

     [CAUTION LIGHT]
     MARKET RISK. As a mutual fund investing in bonds, the Funds are subject to
     the risk that the market value of the bonds will decline because of 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  market  risk,  bonds with  longer  maturities
     generally offer higher yields than bonds with shorter maturities.

                                      10
<PAGE>

   Q What  percentage  of each  Fund's  assets  will  be  invested  in  Florida
     tax-exempt securities?

   A During  normal market  conditions,  at least 80% of each Fund's net assets
     will  consist of Florida  tax-exempt  securities.  This policy may only be
     changed by a shareholder vote.

     In addition to Florida tax-exempt securities, securities issued by certain
     U.S. territories and possessions such as Puerto Rico, the Virgin  Islands,
     and Guam are exempt  from federal  income  tax  and  the  state intangible
     personal property tax; and as such, we  may  consider  investing up to 20%
     of each Fund's assets in these securities.

   Q Are each Fund's investments diversified in many different issuers?

   A Each Fund is considered  diversified  under the federal  securities  laws.
     This  means that we will not  invest  more than 5% in any one issuer  with
     respect to 75% of each Fund's assets. With respect to the remaining 25% of
     each  Fund's  assets,  we could  invest  more than 5% in any one, or more,
     issuers.   Purchases  of  securities  issued  or  guaranteed  by  the U.S.
     Government or its agencies or instrumentalities are not counted toward the
     5%  limitation.  Each Fund,  of  course,  is  concentrated  geographically
     through the purchase of Florida tax-exempt securities.

     With  respect to  the Florida  Tax-Free  Money  Market  Fund,  strict  SEC
     guidelines do not  permit us to invest,  with respect to 75% of the Fund's
     assets,  greater than 10% of the  Fund's total assets in securities issued
     by or subject to guarantees by the same institution.

     We also  may not  invest  more  than 25% of the  Funds'  total  assets  in
     securities  issued in  connection  with the  financing  of  projects  with
     similar characteristics,  such as toll road revenue bonds, housing revenue
     bonds, or electric power project  revenue bonds, or in industrial  revenue
     bonds which are based,  directly or  indirectly,  on the credit of private
     entities of any one industry. However, we reserve the right to invest more
     than 25% of the  Funds'  total  assets in  tax-exempt  industrial  revenue
     bonds.

   Q What are the potential risks  associated with  concentrating  such a large
     portion of each Fund's assets in one state?

   [CAUTION LIGHT]
   A The Funds are  subject to credit and market  risks,  as  described  above,
     which could be magnified by the Funds' concentration in

                                      11
<PAGE>

     Florida  issues.  Florida   tax-exempt  securities   may  be  affected  by
     political,  economic,  regulatory,  or  other  developments that limit the
     ability of Florida issuers to pay interest  or repay principal in a timely
     manner.  Therefore,  the Funds are affected  by events within Florida to a
     much greater degree than a more diversified national fund.

     A particular development may not directly relate to the Funds' investments
     but  nevertheless might  depress the  entire market  for the  state's tax-
     exempt securities and therefore adversely impact the Funds' valuation.

     An  investment  in the Florida  Tax-Free  Money Market Fund may be riskier
     than an  investment  in other types of money market funds  because of this
     concentration.

     The  following  are  examples  of just some of the events that may depress
     valuations  for Florida  tax-exempt securities  for an extended  period of
     time:

     o Changes  in state  laws,  including  voter  referendums,  that  restrict
       revenues or raise costs for issuers.

     o Court  decisions  that affect a category  of  municipal  bonds,  such as
       municipal lease obligations or electric utilities.

     o Natural disasters such as floods, storms,  hurricanes,  droughts, fires,
       or earthquakes.

     o Bankruptcy or financial distress of a prominent  municipal issuer within
       the state.

     o Economic issues that impact critical  industries or large  employers  or
       that weaken real estate prices.

     o Reductions in federal or state financial aid.

     o Imbalance in the supply and demand for the state's municipal securities.

     o Developments  that may change  the tax  treatment  of Florida tax-exempt
       securities.

     In addition,  because each Fund invests in securities  backed by banks and
     other  financial  institutions,  changes  in the  credit  quality of these
     institutions could cause losses to a Fund and affect its share price.

     Other   considerations   affecting  the  Funds'   investments  in  Florida
     tax-exempt  securities  are   summarized  in  the  Statement of Additional
     Information under SPECIAL RISK CONSIDERATIONS.

                                      12
<PAGE>

   Q Will any portion of the distributions from the Funds be subject to federal
     income taxes?

   A During normal market conditions, at least 80% of each Fund's annual income
     will be excluded from gross income for federal income tax purposes and the
     shares will be exempt from the Florida  intangible  personal property tax.
     This policy may only be changed by a shareholder vote.  We expect that any
     taxable interest income distributed will be minimal.

     However,  gains and losses from trading  securities  that occur during the
     normal  course  of  managing  a fund  may  create  capital  gain  or  loss
     distributions.   The  Internal   Revenue  Code   presently   treats  these
     distributions differently than tax-exempt interest income in the following
     ways:

     o Distributions  of net  short-term  capital gains are taxable as ordinary
       income.

     o Distributions  of net  long-term  capital gains are taxable as long-term
       capital  gains,  regardless of the length of time you have held the Fund
       shares.

     o Both short-term and long-term capital gains are taxable whether received
       in cash or reinvested in additional shares.

   Q Will income from the Funds be subject to the federal  alternative  minimum
     tax (AMT) for individuals?

   A During normal market conditions, at least 80% of each Fund's annual income
     will be excluded from the calculation of the federal  alternative  minimum
     tax  (AMT)  for  individuals.  This  policy  may  only  be  changed  by  a
     shareholder  vote.  Since  inception,  the Funds have not  distributed any
     income that  is subject to  the federal AMT for individuals, and we do not
     intend  to invest  in securities  subject to the federal AMT.  However, of
     course,  changes in  federal tax  laws or  other unforeseen  circumstances
     could result in income subject to the federal AMT for individuals.

 Florida Tax-Free Income Fund

   Q What is the credit quality of the Fund's investments?

   A Under normal market  conditions,  we will invest the Fund's assets so that
     at least 50% of the total market  value of the  tax-exempt  securities  is
     rated within the three highest  long-term rating  categories (A or

                                      13
<PAGE>

     higher) by Moody's Investors Service,  Inc.  (Moody's),  Standard & Poor's
     Ratings Group (S&P), or Fitch IBCA, Inc. (Fitch) or in the highest  short-
     term  rating category  by Moody's,  S&P, or Fitch; or if a security is not
     rated by these rating agencies, we must determine that the security  is of
     equivalent investment quality.

     In no event will we purchase a security for the Fund unless it is rated at
     least  investment   grade  at  the  time  of  purchase.   Investment-grade
     securities are those  securities  rated within the four highest  long-term
     rating  categories  by  Moody's  (Baa or  higher),  S&P,  or Fitch (BBB or
     higher),  or in the two  highest  short-term  rating  categories  by these
     rating agencies;  or if unrated by these agencies,  we must determine that
     the securities are of equivalent investment quality.

     You will find a complete  description of the above  tax-exempt  ratings in
     the Funds' Statement of Additional Information.

   Q What happens if the rating of a security is downgraded to below investment
     grade?

   A 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 How does the portfolio manager decide which securities to buy and sell?

   A We manage  tax-exempt  funds based on the common  sense  premise  that our
     investors   value   tax-exempt   income   over   taxable   capital   gains
     distributions.  When  weighing our decision to buy or sell a security,  we
     strive to balance the value of the tax-exempt  income,  the credit risk of
     the issuer, and the price volatility of the bond.

   Q What is the Fund's average portfolio maturity and how is it calculated?

   A While the Fund's average portfolio  maturity is not restricted,  we expect
     it to be greater than 10 years.  To  determine a  security's  maturity for
     purposes of calculating  the Fund's  average  portfolio  maturity,  we may
     estimate  the  expected  time in which the  security's  principal is to be
     paid.  This can be  substantially  shorter than its stated final maturity.

     INVESTMENT POLICIES in the Funds' Statement of Additional Information.

 Florida Tax-Free Money Market Fund

   Q What is the credit quality of the Fund's investments?

   A The Fund's  investments  consist of securities meeting the requirements to
     qualify as "eligible  securities"  under the SEC rules applicable to money
     market funds.  In general,  an eligible  security is defined as a security
     that is:

     o issued  or  guaranteed   by  the  U.S.   Government  or  any  agency  or
       instrumentality   thereof  including   "prerefunded"  and  "escrowed  to
       maturity" tax-exempt securities;

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

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

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

     In addition,  we must consider  whether a particular  investment  presents
     minimal credit risk.

   Q Who are the Nationally Recognized Statistical Rating Organizations?

   A Current NRSROs include:

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

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

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

                                      15

   Q Will the Fund always maintain a net asset value of $1 per share?

     [CAUTION LIGHT]
   A While we will  endeavor to maintain a constant  Fund net asset value of $1
     per share,  there is no assurance that we will be able to do so. Remember,
     the shares are neither insured nor guaranteed by  the U.S. Government.  As
     such, the Fund carries some risk.

     For example,  there is always a risk that the issuer of a security held by
     the Fund will fail to pay  interest or  principal  when due. We attempt to
     minimize this credit risk by investing only in securities  rated in one of
     the two highest categories for short-term securities, or, if not rated, of
     comparable  quality,  at the time of purchase.  Additionally,  we will not
     purchase  a security  unless  our  analysts  determine  that the  security
     presents minimal credit risk.

     There is also a risk that  rising  interest  rates will cause the value of
     the Fund's  securities  to decline.  We attempt to minimize  this interest
     risk by limiting  the  maturity  of each  security to 397 days or less and
     maintaining a dollar-weighted  average portfolio  maturity for the Fund of
     90 days or less.

                                 ITS MATURITY,
                                  THEN ADDING
                            THOSE FIGURES TOGETHER
                               AND DIVIDING THE
                                 TOTAL BY THE
                                 DOLLAR VALUE
                                 OF THE FUND'S
                                  PORTFOLIO.

     Finally, there is the possibility that one or more investments in the Fund
     cease to be "eligible securities" resulting in the net asset value ceasing
     to be $1 per share.  For  example,  a guarantor  on a security may fail to
     meet a contractual obligation.

   Q How does the portfolio manager decide which securities to buy and sell?

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

For additional  information  about other securities in which we may invest each
Fund's assets, see APPENDIX A on page 30.

FUND MANAGEMENT

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

                                      16
<PAGE>

We provide management  services to the Funds pursuant to an Advisory Agreement.
We are responsible for managing the Funds' portfolios  (including  placement of
brokerage  orders) and their  business  affairs,  subject to the  authority and
supervision  by the Board of Trustees.  For  our services,  the Funds pay us an
annual fee. This fee, which is accrued daily and  paid monthly, is computed  as
a percentage of the aggregate average  net assets of both Funds combined.  This
fee is allocated between the Funds based on the  relative net assets  of  each.
The fee is computed at one-half of one percent (.50%) of the first $50  million
of  average net assets,  two-fifths of one percent  (.40%)  of that portion  of
average net assets over $50 million but not over $100 million, and three-tenths
of  one percent (.30%)  of that portion of average net assets in excess of $100
million. The fees we received for the fiscal year ended March 31, 1998,  net of
reimbursements,  were equal to  .36% of  average  net  assets  for the  Florida
Tax-Free Income Fund and .35% of average net assets for  the  Florida  Tax-Free
Money Market Fund. We reimbursed the Florida  Tax-Free  Income Fund $10,032 and
the  Florida Tax-Free  Money Market  Fund  $20,954  for their  Total  Operating
Expenses in excess of the .50%  limitation. We also provide services related to
selling the Funds' shares and receive no compensation for those services.

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

USING MUTUAL FUNDS IN AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

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

II. Using Funds in an Investment Program

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

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.

For example,  assume you wish to pursue the higher yields usually  available in
the long-term bond market,  but you are also concerned about the possible price
swings of the long-term bonds.  You could divide your  investments  between the
Florida  Tax-Free Income Fund and the Florida  Tax-Free Money

                                      18
<PAGE>

Market Fund. This would create a portfolio with a higher yield than that of the
money market and less  volatility  than that of the long-term  market.  This is
just one way you could combine funds to fit your own risk and reward goals.

III. USAA's Family of Funds

We offer you another  alternative  with our asset  strategy  funds listed under
asset allocation on page 34. These unique mutual funds provide a professionally
managed diversified investment portfolio within a mutual fund. Designed for the
individual  who  prefers  to  delegate  the  asset  allocation  process  to  an
investment manager, their structure achieves diversification across a number of
investment categories.

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

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT

You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required for new accounts.   However, after you open your
initial  account  with us,  you  will not need to fill out  another application
unless the registration is different.

TAX ID NUMBER

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

EFFECTIVE DATE

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

                                      19

charge may be assessed in the clearing process, which will be deducted from the
amount of the purchase.

PHONE  1-800-531-8448

o   If you have an existing  USAA  account and would like to open a new account
    or exchange to another USAA fund, call for instructions. To open an account
    by phone, the new account must have the same  registration as your existing
    account.

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day.

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase  by bank  wire or  certified  check to avoid  delay.  Redemptions  are
subject to income tax based on the  difference  between the cost of shares when
purchased and the price received upon redemption.

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

HOW TO REDEEM

WRITTEN, FAX, TELEGRAPH, OR TELEPHONE

       USAA Shareholder Account Services
       9800 Fredericksburg Road

    Account Services.
o   Call toll free 1-800-531-8448, in San Antonio, 456-7202.

Telephone redemption privileges are automatically established when you complete
your application.  The Fund will employ  reasonable  procedures to confirm that
instructions  communicated by telephone are genuine; and if it does not, it may
be liable for any losses due to unauthorized or fraudulent instructions. Before
any discussion regarding your account, we obtain the

                                      21
<PAGE>

following information:  (1) USAA number or  account number,  (2) the name(s) on
the account registration,  and (3) social security number or tax identification
number  for the   account  registration.  In  addition, we record all telephone
communications  with you  and send confirmations of account transactions to the
address  of record.  Redemption by telephone, fax, or telegram is not available
for shares represented by stock certificates.

CHECKWRITING

o   Checks can be issued for your Florida  Tax-Free  Money Market Fund account.
    Return a signed signature card,  which  accompanies  your  application,  or
    request a signature card separately and return to:
       USAA Shareholder Account Services
       9800 Fredericksburg Road
       San Antonio, TX 78288

You will not be charged for the use of checks or any subsequent reorders.  Your
checkwriting  privilege  is subject to State  Street  Bank and Trust  Company's
rules and regulations governing checking accounts.  You may write checks in the
amount of $250 or more.  Checks  written  for less  than $250 will be  returned
unpaid.  Because the value of your account  changes daily as dividends  accrue,
you may not write a check to close your account.

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
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

Beginning  in  September  1998,  and  occurring   annually   thereafter,   USAA
Shareholder  Account  Services (SAS),  the Funds' transfer agent,  may 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

                                      22
<PAGE>

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:

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

o   limit or  discontinue  the offering of shares of any portfolio of the Trust
    without notice to the shareholders;

o   impose a  redemption  charge of up to 1% of the net  asset  value of shares
    redeemed if circumstances indicate a charge is necessary for the protection
    of remaining  investors  (for  example,  if excessive  market-timing  share
    activity unfairly burdens  long-term  investors);  however,  this 1% charge
    will not be imposed upon  shareholders  unless  authorized  by the Board of
    Trustees and the required notice has been given to shareholders;

o   require a  signature  guarantee  for  transactions  or  changes  in account
    information in those  instances  where the  appropriateness  of a signature
    authorization  is in  question.  The  Statement of  Additional  Information
    contains information on acceptable guarantors;

o   redeem an account with a total value of less than $500 of either Fund, with
    certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered in your state of residence.  Only Florida residents may exchange into a
Florida Fund. The Funds' transfer agent will  simultaneously  process  exchange
redemptions  and  purchases  at the  share  prices  next  determined  after the
exchange  order  is  received.  The  investment  minimums  applicable  to share
purchases also apply to exchanges. For federal income tax purposes, an exchange
between Funds is a taxable  event;  and as such, you may realize a capital gain
or loss.  Exchanges are based on the difference between the cost of shares when
purchased and the price received upon exchange.

The Funds have undertaken certain procedures  regarding telephone  transactions
as described on page 21.

                                      23

Exchange Limitations, Excessive Trading

To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds).

Share Price Calculation

The price at which you  purchase  and  redeem  Fund  shares is equal to the net
asset value (NAV) per share determined on the effective date of the purchase or
redemption.  You may buy and sell Fund  shares  at the NAV per share  without a
sales  charge.  Each  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.

Securities of the Florida  Tax-Free Income Fund are valued each business day at
their current market value as determined by a pricing  service  approved by the
Trust's  Board of  Trustees.  Securities  which cannot be valued by the pricing
service,  and all other  assets,  are valued in good faith at fair value  using
methods  we have  determined  under  the  general  supervision  of the Board of
Trustees.  In addition,  securities  with maturities of 60 days or less and all
securities  of the Florida  Tax-Free  Money Market Fund are stated at amortized
cost, which approximates market value.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Funds' Statement of Additional Information.

Dividends and Distributions

Net  investment  income  of each  Fund is  accrued  daily  and paid on the last
business day of the month.  Dividends shall begin accruing on shares  purchased
the day  following  the  effective  date and  shall  continue  to accrue to the
effective date of redemption.  Any net capital gain distribution usually occurs
within 45 days of the March 31 fiscal year end, which would be somewhere around
the middle of May. The Funds will make additional payments to shareholders,  if
necessary, to avoid the imposition of any federal income or excise tax.

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the  Fund  shares  computed  on the  ex-dividend  date.  Any
capital gain distributions paid by the Florida Tax-Free Income Fund will

                                      24
<PAGE>

reduce the  NAV per  share  by the  amount  of the  dividend  or  distribution.
These  dividends  and  distributions are  subject to  taxes.  If you  become  a
resident   of a  state other  than Florida,  we will  mail a check for proceeds
of income dividends to  you monthly.  We will mail a check for any capital gain
distribution to you after the distribution is paid.

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.  While we manage  the
Funds so that at least 80% of each  Fund's  annual  income  will be exempt from
federal  income  taxes,  we  may  invest  up to 20% of  the  Funds'  assets  in
securities that generate income not exempt from  federal income taxes.  Because
interest  income may be  exempt for  federal income  tax purposes,  it does not
necessarily  mean that  the interest  income may be  exempt under the income or
other tax laws of any state or local taxing authority.  As discussed earlier on
page 13, capital gains  distributions  by a Fund may be taxable.  Note that the
Taxpayer  Relief  Act of 1997 and  regulations  that will  likely be adopted to
implement the Act may affect the status and treatment of certain  distributions
shareholders receive from the Fund. We urge you to consult your own tax adviser
about the status of distributions from the Fund in your own state and locality.

WITHHOLDING  - Federal law requires each Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o   fails to furnish the Fund with a correct tax identification number,
o   underreports dividend or interest income, or
o   fails to certify that he or she is not subject to withholding.

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

REPORTING - Each Fund will report  information to you concerning the tax status
of  dividends  and  distributions  for federal  income tax  purposes  annually,
including  the  portion  of the  dividends  constituting  interest  on  private
activity  bonds and the  percentage  and source of  interest  income  earned on
tax-exempt securities held by the Fund during the preceding year.

Florida Taxation

The  following  is  only a  summary  of  some  of  the  important  Florida  tax
considerations  generally  affecting  the Funds and  their  shareholders.  This
discussion  is not intended as a  substitute  for careful  planning.  Potential
investors  in the  Funds  should  consult  their  tax  advisers  with  specific
reference to their own tax situations.

Dividends and distributions  paid by the Funds to individuals who are residents
of  Florida  are not  taxable by  Florida,  because  Florida  does not impose a
personal income tax.  Dividends and  distributions by the Funds will be subject
to  Florida  corporate  income  taxes.  Accordingly,  investors  in the  Funds,
including in particular  corporate investors that may be subject to the Florida
corporate  income tax,  should  consult  their tax advisers with respect to the
application  of  the  Florida  corporate  income  tax to the  receipt  of  Fund
dividends  and  distributions  and to the  investor's  Florida tax situation in
general.

Florida  imposes  a tax  on  intangible  personal  property  owned  by  Florida
residents.  The Funds received a ruling from the Florida  Department of Revenue
that if, on the last business day of any calendar year, the Funds'  investments
consist solely of assets exempt from the Florida  intangible  personal property
tax,  shares of the Funds  owned by Florida  residents  will be exempt from the
Florida  intangible  personal property tax in the following year. Assets exempt
from the Florida intangible personal property tax include obligations issued by
the State of Florida and its political subdivisions, municipalities, and public
authorities;  obligations  of the U.S.  Government,  its  agencies  and certain
territories and possessions such as Puerto Rico, the Virgin Islands,  and Guam;
and cash.  If shares of the Funds are  subject to Florida  intangible  personal
property tax,  because less than 100% of the Funds' assets on the last business
day of the calendar year consist of assets  exempt from the Florida  intangible
personal property tax, only the portion of the net asset value of shares of the
Funds that is attributable to obligations of the U.S. Government will be exempt
from taxation.

Year 2000

Like  other  organizations  around  the  world,  the Funds  could be  adversely
affected if the computer systems used by the Funds, their service providers, or
companies  in which the Funds  invest do not  properly  process  and  calculate
date-related  information  beginning  on January 1,  2000,  a problem  commonly
referred to as the "Year 2000 Problem." We and our USAA  affiliates  have taken
steps to address any  potential  Year 2000 Problem  with the computer  programs
used by the Funds, us, and other USAA companies.  We expect USAA programs to be
fully  compliant  by some  time  during  the  first  half of 1999.  We are also
actively  reviewing the steps being taken by our third-party  service providers
as well as those of the Funds to address the Year 2000  Problem.  Those reviews
include site visits of the principal service providers.  At this time, however,
there can be no  assurance  that the  steps  being  taken by USAA,  third-party
service providers, or companies in which the Funds invest will be sufficient to
avoid adverse impact to the Funds for the Year 2000 Problem.

                                   APPENDIX A

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

VARIABLE RATE SECURITIES

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

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

In the case of the Florida  Tax-Free  Money Market Fund only, any variable rate
instrument  with a demand  feature  will be deemed to have a maturity  equal to
either  the date on which the  underlying  principal  amount  may be  recovered
through demand or the next rate  adjustment  date  consistent  with  applicable
regulatory requirements.

PUT BONDS

We may invest a Fund's assets 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.  For the Florida  Tax-Free Income Fund,
maturity  for put  bonds is  deemed  to be the date on  which  the put  becomes
exercisable.  Generally,  maturity for put bonds for the Florida Tax-Free Money
Market Fund is determined as stated under Variable Rate Securities.

ZERO COUPON BONDS

We may invest a Fund's  assets 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,  each Fund records as income the
daily amortization of the purchase discount.

                                      30
<PAGE>

WHEN-ISSUED SECURITIES

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

o   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.
o   The Funds do not earn interest on the securities until settlement,  and the
    market  value  of  the  securities  may  fluctuate   between  purchase  and
    settlement.
o   Such securities can be sold before settlement date.

MUNICIPAL LEASE OBLIGATIONS

We may invest a Fund's assets in a variety of instruments  commonly referred to
as municipal lease obligations, including:

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

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.

LIQUIDITY

We may invest up to 15% of the net assets of the Florida Tax-Free Income Fund's
market value and up to 10% of the Florida  Tax-Free  Money Market Fund's market
value  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.

Lease obligations and certain put bonds subject to restrictions on transfer may
be determined to be liquid in accordance with the guidelines established by the
Funds' Board of Trustees.

In determining the liquidity of a lease obligation,  we will consider:  (1) the
frequency  of trades  and quotes  for the lease  obligation;  (2) the number of
dealers  willing to  purchase  or sell the lease  obligation  and the number of
other  potential  purchasers;  (3) dealer  undertakings to make a market in the
lease obligation;  (4) the nature of the marketplace trades, including the time
needed to dispose of the lease obligation, the method of soliciting offers, and
the mechanics of transfer;  (5) whether the lease  obligation is of a size that
will be attractive to institutional investors; (6) whether the lease obligation
contains a  non-appropriation  clause and the likelihood  that the obligor will
fail to make an  appropriation  therefor;  and (7) such  other  factors  as the
Manager may determine to be relevant to such determination.

In determining  the liquidity of put bonds with  restrictions  on transfer,  we
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 put bond.

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

WHAT ARE EACH FUND'S INVESTMENT OBJECTIVES AND MAIN STRATEGIES?

Each Fund has a common investment objective of providing Texas investors with a
high level of current interest income that is exempt from federal income taxes.
The Texas  Tax-Free  Money Market Fund has a further  objective  of  preserving
capital and maintaining  liquidity.  Each Fund has separate investment policies
to achieve its objective.

The TEXAS TAX-FREE INCOME FUND invests primarily in long-term, investment-grade
Texas  tax-exempt  securities.  The Fund's  average  portfolio  maturity is not
restricted, but is expected to be greater than 10 years.

The TEXAS TAX-FREE MONEY MARKET FUND invests in high-quality  Texas  tax-exempt
securities with maturities of 397 days or less.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that these objectives will be achieved.  See FUND INVESTMENTS on page
8 for more information.

MAIN RISKS OF INVESTING IN THESE FUNDS

The two primary  risks of  investing  in these Funds are credit risk and market
risk. As with other mutual funds, losing money is an additional risk associated
with investing in these Funds.

o   CREDIT RISK  involves the  possibility  that a borrower  cannot make timely
    interest and principal payments on its securities.

o   MARKET  RISK  involves  the  possibility  that  the  value  of each  Fund's
    investments  will  decline  due to an increase  in  interest  rates,  or to
    adverse  changes in supply and demand for  municipal  securities,  or other
    market factors.

These credit and market risks may be magnified  because each Fund  concentrates
in Texas tax-exempt securities

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

IF INTEREST RATES DECREASE:  the yield of each Fund may decrease and the market
value of the Texas Tax-Free Income Fund's securities may increase, which  would
likely increase the Fund's net asset value and total return. The Texas Tax-Free
Money Market Fund's total return may decrease.

                                       2

As you consider an  investment  in any Fund,  you should also take into account
your tolerance for the daily  fluctuations of the financial markets and whether
you can afford to leave your money in this  investment for long periods of time
to ride out down periods.

An investment in either Fund is not a deposit of USAA Federal  Savings Bank and
is not insured or guaranteed by the Federal  Deposit  Insurance  Corporation or
any other  government  agency.  Although the Texas  Tax-Free  Money Market Fund
seeks to preserve the value of your  investment at $1 per share, it is possible
to lose money by investing in that Fund.

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

COULD THE VALUE OF YOUR INVESTMENT IN THESE FUNDS FLUCTUATE?

Yes, it could.  In fact,  the value of your  investment  in the Texas  Tax-Free
Income Fund likely will  increase  or  decrease.  However,  we manage the Texas
Tax-Free  Money Market Fund in accordance  with strict  Securities and Exchange
Commission guidelines designed to preserve the Fund's value at $1 per share.

The value of the  securities  in which the Texas  Tax-Free  Income Fund invests
typically  fluctuates  inversely  with changes in the general level of interest
rates.  Changes in the  creditworthiness of issuers and changes in other market
factors such as the  relative  supply of and demand for  tax-exempt  bonds also
create value  fluctuations.  The bar charts shown below  illustrate  the Funds'
volatility and performance from year to year over the life of the Funds.

All mutual funds must use the same  formulas to calculate  yield and  effective
yield.

Texas Tax-Free Income Fund

The Texas Tax-Free  Income Fund may advertise  performance in terms of a 30-day
yield  quotation or a tax  equivalent  yield.  The Fund's  30-day yield for the
period ended March 31, 1998, was 4.70%.

                                  REINVESTED.

The Texas Tax-Free Money Market Fund typically advertises  performance in terms
of a 7-day yield and effective yield or tax equivalent  yield and may advertise
total return.  The 7-day yield quotation more closely reflects current earnings
of the Fund  than the total  return  quotation.  The  effective  yield  will be
slightly higher than the yield because of the compounding effect of the assumed
reinvestment. Current yields and effective yields fluctuate daily and will vary
with factors such as interest rates and the quality, length of maturities,  and
type of  investments  in the  portfolio.  The Fund's 7-day yield for the period
ended March 31, 1998, was 3.37%.

You may obtain the Fund's most  current  yield and  effective  yield by calling
1-800-531-8777.

TAX EQUIVALENT YIELD

Investors use tax equivalent  yields to compare  taxable and  tax-exempt  fixed
income  investments  using a common yield measure.  The tax equivalent yield is
the  yield  that a fully  taxable  investment  must  generate  to earn the same
"take-home" yield as a tax-exempt investment. The calculation depends upon your
federal  marginal  tax rate and  assumes  that an  investor  can fully  itemize
deductions  on his or her  federal tax return.  The higher  your  marginal  tax
bracket,  the higher will be the tax equivalent  yield and the more valuable is
the Fund's tax exemption.

For example,  if you assume a federal  marginal tax rate of 36%, the Funds' tax
equivalent yields for the period ending March 31, 1998, would be as follows:

Money Market Fund,  you must find a fully taxable  investment  that yields more
than 5.27%.

FUND INVESTMENTS

Principal Investment Strategies and Risks

   Q   What is each Fund's principal investment strategy?

   A   We will  attempt to achieve  each Fund's  objective  by  investing  each
       Fund's assets primarily in securities  issued by the State of Texas, its
       political subdivisions and instrumentalities,  and by other governmental
       entities,  if,  in the  opinion  of  counsel,  the  interest  from  such
       obligations  is  excluded  from  gross  income  for  federal  income tax
       purposes.

       Currently, Texas does not have a personal state income tax. In the event
       Texas does enact a personal state income or similar tax, we will attempt
       to seek a high level of current  interest  income  also exempt from such
       tax. The ability of the Funds to pursue this further policy,  of course,
       will be affected by the actual form of such a tax.

       These  securities  include  municipal  debt  obligations  that have been
       issued by Texas and its  political  subdivisions,  and duly  constituted
       state  and  local  authorities  and  corporations.  We  refer  to  these
       securities as Texas tax-exempt  securities.  Texas tax-exempt securities
       are issued to fund public  infrastructure  projects  such as streets and
       highways,  schools,  water and sewer systems,  hospitals,  and airports.
       They may also be issued to refinance outstanding

                                       8
<PAGE>

       obligations as well as to obtain  funds for general  operating  expenses
       and for loans to other  public institutions and facilities.

       Because the projects benefit the public,  Congress has granted exemption
       from federal  income taxes for the  interest  income  arising from these
       securities.


   Q   What types of tax-exempt  securities  will be  included  in each  Fund's
       portfolio?

   A   Each Fund's assets may be invested  in any of the  following  tax-exempt
       securities:

       o   general obligation bonds which are secured by the issuer's pledge of
           its  full  faith,  credit,  and  taxing  power  for the  payment  of
           principal and interest;

       o   revenue  bonds which are payable  from the  revenue  derived  from a
           particular  facility or class of facilities or, in some cases,  from
           annual   appropriations  made  by  the  state  legislature  for  the
           repayment  of  interest  and  principal  or other  specific  revenue
           source, but not from the general taxing power;

       o   lease obligations  backed by the  municipality's  covenant to budget
           for the payments due under the lease obligation; and

       o   industrial  development  bonds  issued  by or on  behalf  of  public
           authorities to obtain funds for privately-operated facilities.

       As a temporary defensive measure because of market, economic, political,
       or other  conditions,  we may invest up to 100% of each Fund's assets in
       short-term securities whether or not they are exempt from federal income
       tax.  To the extent that these  temporary  investments  produce  taxable
       income,  that  income  may result in that Fund not fully  achieving  its
       investment objective.


   Q   What are the principal risks associated  with  investments in tax-exempt
       securities?

   A   The two principal risks of investing in tax-exempt securities are credit
       risk and market risk.

       [CAUTION LIGHT}
       CREDIT RISK.  Credit risk is the  possibility  that an issuer of a fixed
       income  security  will  fail to make  timely  payments  of  interest  or
       principal.  We attempt to minimize the Funds'  credit risks by investing
       in  securities  considered  at  least  investment  grade  at the time of
       purchase.  Nevertheless, even investment-grade securities are subject to
       some credit risk. In addition,  the ratings of securities  are estimates
       by the rating  agencies  of the credit  quality of the

                                       9
<PAGE>

       securities.  The ratings  may not  take into  account  every  risk  that
       interest or principal will be repaid on a timely basis.

       When evaluating  potential  investments for the Funds, our analysts also
       independently assess credit risk and its impact on the Funds' portfolio.
       Securities in the lowest  investment  grade ratings  category (BBB) have
       speculative  grade  characteristics.  Changes in economic  conditions or
       other  circumstances are more likely to lead to a weakened capability to
       make  principal and interest  payments on these  securities  than is the
       case for higher-rated securities.

       [CAUTION LIGHT]
       MARKET RISK. As a mutual fund investing in bonds,  the Funds are subject
       to the risk that the market value of the bonds will  decline  because of
       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 market risk,  bonds with
       longer maturities  generally offer higher yields than bonds with shorter
       maturities.

   Q   What  percentage of  each Fund's  assets will  be invested in Texas tax-
       exempt securities?

   A   During normal market conditions,  at least 80% of each Fund's net assets
       will  consist of Texas  tax-exempt  securities.  This policy may only be
       changed by a shareholder vote.

       In addition to Texas tax-exempt securities, securities issued by certain
       U.S.  territories  and  possessions  such as  Puerto  Rico,  the  Virgin
       Islands,  and Guam are exempt from federal personal income taxes; and as
       such, we may consider investing up to 20% of each Fund's assets in these
       securities.

   Q   Are each Fund's investments diversified in many different issuers?

   A   Each Fund is considered  diversified under the federal  securities laws.
       This means that we will not invest  more than 5% in any one issuer  with
       respect to 75% of each Fund's assets.  With respect to the remaining 25%
       of each Fund's assets, we could invest more than 5% in any one, or more,
       issuers.  Purchases  of  securities  issued  or  guaranteed  by the U.S.
       Government or its agencies or  instrumentalities  are not counted toward
       the 5% limitation.  Each Fund, of course, is concentrated geographically
       through the purchase of Texas tax-exempt securities.

                                      10
<PAGE>

       With respect to the Texas Money Market Fund,  strict SEC  guidelines  do
       not permit us to  invest,  with  respect  to 75% of the  Fund's  assets,
       greater than 10% of the Fund's total assets in  securities  issued by or
       subject to guarantees by the same institution.

       We also may not  invest  more  than 25% of the  Funds'  total  assets in
       securities  issued in  connection  with the  financing of projects  with
       similar  characteristics,  such  as toll  road  revenue  bonds,  housing
       revenue bonds, or electric power project revenue bonds, or in industrial
       revenue bonds which are based, directly or indirectly,  on the credit of
       private entities of any one industry.  However,  we reserve the right to
       invest more than 25% of the Funds' total assets in tax-exempt industrial
       revenue bonds.

   Q   What are the potential risks associated with  concentrating such a large
       portion of each Fund's assets in one state?

       [CAUTION LIGHT]
   A   The Funds are subject to credit and market  risks,  as described  above,
       which could be magnified by the Funds'  concentration  in Texas  issues.
       Texas  tax-exempt  securities  may be affected by  political,  economic,
       regulatory,  or other  developments  that  limit  the  ability  of Texas
       issuers  to  pay  interest  or  repay  principal  in  a  timely  manner.
       Therefore,  the Funds are  affected  by  events  within  Texas to a much
       greater degree than a more diversified national fund.

       A  particular   development  may  not  directly  relate  to  the  Funds'
       investments  but  nevertheless  might  depress the entire market for the
       state's tax-exempt  securities and therefore adversely impact the Funds'
       valuation.

       An  investment  in the Texas  Tax-Free  Money Market Fund may be riskier
       than an  investment in other types of money market funds because of this
       concentration.

       The  following  are examples of just some of the events that may depress
       valuations for Texas  tax-exempt  securities  for an extended  period of
       time:

       o   Changes in state laws,  including voter  referendums,  that restrict
           revenues or raise costs for issuers.

       o   Court decisions that affect a category of municipal  bonds,  such as
           municipal lease obligations or electric utilities.

       o   Natural  disasters such  as floods,  storms,  hurricanes,  droughts,
           fires, or earthquakes.

       o   Bankruptcy or  financial  distress of a prominent  municipal  issuer
           within the state.

                                      11
<PAGE>

       o   Economic issues that impact  critical  industries or large employers
           or that weaken real estate prices.

       o   Reductions in federal or state financial aid.

       o   Imbalance in  the  supply  and  demand  for  the  state's  municipal
           securities.

       o   Developments that may change the tax  treatment of Texas  tax-exempt
           securities.

       In addition, because each Fund invests in securities backed by banks and
       other  financial  institutions,  changes in the credit  quality of these
       institutions could cause losses to a Fund and affect its share price.

       Other   considerations   affecting  the  Funds'   investments  in  Texas
       tax-exempt  securities  are  summarized  in the  Statement of Additional
       Information under SPECIAL RISK CONSIDERATIONS.

   Q   Will  any portion  of the  distributions  from the  Funds be  subject to
       federal income taxes?

   A   During  normal  market  conditions,  at least 80% of each Fund's  annual
       income  will be  excluded  from  gross  income  for  federal  income tax
       purposes.  This  policy may only be changed by a  shareholder  vote.  We
       expect that any taxable interest income distributed will be minimal.

       However,  gains and losses from trading securities that occur during the
       normal  course  of  managing  a fund  may  create  capital  gain or loss
       distributions.   The  Internal   Revenue  Code  presently  treats  these
       distributions   differently  than  tax-exempt  interest  income  in  the
       following ways:

       o   Distributions  of  net  short-term  capital  gains  are  taxable  as
           ordinary income.

       o   Distributions  of  net  long-term   capital  gains  are  taxable  as
           long-term  capital gains,  regardless of the length of time you have
           held the Fund shares.


       o   Both  short-term  and long-term  capital  gains are taxable  whether
           received in cash or reinvested in additional shares.


   Q   Will income from the Funds be subject to the federal alternative minimum
       tax (AMT) for individuals?

   A   During  normal  market  conditions,  at least 80% of each Fund's  annual
       income will be excluded from the calculation of the federal  alternative
       minimum tax (AMT) for individuals. This policy may

                                      12
<PAGE>

       only be changed by a shareholder  vote. Since  inception, the Funds have
       not  distributed  any  income that  is subject  to the  federal AMT  for
       individuals, and we do not intend to invest in securities subject to the
       federal AMT.  However,  of course,  changes in federal tax laws or other
       unforeseen circumstances could  result in income subject  to the federal
       AMT for individuals.

Texas Tax-Free Income Fund

   Q   What is the credit quality of the Fund's investments?


   A   Under normal market conditions, we will invest the Fund's assets so that
       at least 50% of the total market value of the  tax-exempt  securities is
       rated within the three highest long-term rating categories (A or higher)
       by Moody's Investors Service, Inc. (Moody's),  Standard & Poor's Ratings
       Group (S&P),  or Fitch IBCA, Inc.  (Fitch) or in the highest  short-term
       rating category by Moody's, S&P, or Fitch; or if a security is not rated
       by these  rating  agencies,  we must  determine  that the security is of
       equivalent investment quality.

       In no event will we purchase a security  for the Fund unless it is rated
       at least  investment  grade at the  time of  purchase.  Investment-grade
       securities are those securities rated within the four highest  long-term
       rating  categories  by Moody's  (Baa or  higher),  S&P, or Fitch (BBB or
       higher),  or in the two highest  short-term  rating  categories by these
       rating agencies; or if unrated by these agencies, we must determine that
       the securities are of equivalent investment quality.

       You will find a complete  description of the above tax-exempt ratings in
       the Funds' Statement of Additional Information.

   Q   What  happens if  the rating  of  a  security  is  downgraded  to  below
       investment grade?

   A   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.

                                      13
<PAGE>

   Q   How does the portfolio manager decide which securities to buy and sell?

   A   We manage  tax-exempt  funds based on the common sense  premise that our
       investors   value   tax-exempt   income  over  taxable   capital   gains
       distributions.  When weighing our decision to buy or sell a security, we
       strive to balance the value of the tax-exempt income, the credit risk of
       the issuer, and the price volatility of the bond.

   Q   What is the Fund's average portfolio maturity and how is it calculated?

   A   While the Fund's average portfolio maturity is not restricted, we expect
       it to be greater than 10 years.  To determine a security's  maturity for
       purposes of calculating the Fund's average  portfolio  maturity,  we may
       estimate the expected  time in which the  security's  principal is to be
       paid. This can be substantially  shorter than its stated final maturity.
       For more  information  on the method of  calculating  the Fund's average
       weighted  portfolio  maturity,  see  INVESTMENT  POLICIES  in the Funds'
       Statement of Additional Information.

Texas Tax-Free Money Market Fund

   Q   What is the credit quality of the Fund's investments?

   A   The Fund's investments consist of securities meeting the requirements to
       qualify as "eligible securities" under the SEC rules applicable to money
       market funds. In general,  an eligible security is defined as a security
       that is:

       o   issued  or guaranteed  by the  U.S.  Government  or  any  agency  or
           instrumentality  thereof  including  "prerefunded" and "escrowed  to
           maturity" tax-exempt securities;

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

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

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

                                      14
<PAGE>

       In addition,  we must consider whether a particular  investment presents
       minimal credit risk.


   Q   Who are the Nationally Recognized Statistical Rating Organizations?

   A   Current NRSROs include:

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

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

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

   Q   Will the Fund always maintain a net asset value of $1 per share?

       [CAUTION LIGHT]
   A   While we will endeavor to maintain a constant Fund net asset value of $1
       per  share,  there  is no  assurance  that  we will  be able  to do  so.
       Remember,  the  shares are  neither  insured nor  guaranteed by the U.S.
       Government. As such, the Fund carries some risk.

       For example,  there is always a risk that the issuer of a security  held
       by the Fund will fail to pay interest or principal  when due. We attempt
       to minimize this credit risk by investing  only in  securities  rated in
       one of the two highest categories for short-term securities,  or, if not
       rated, of comparable quality, at the time of purchase.  Additionally, we
       will not  purchase a security  unless our  analysts  determine  that the
       security presents minimal credit risk.

       There is also a risk that rising  interest rates will cause the value of
       the Fund's  securities to decline.  We attempt to minimize this interest
       risk by limiting the  maturity of each  security to 397 days or less and
       maintaining a dollar-weighted average portfolio maturity for the Fund of
       90 days or less.

                               AND DIVIDING THE
                                 TOTAL BY THE

                                 OF THE FUND'S
                                  PORTFOLIO.

       Finally,  there is the possibility  that one or more  investments in the
       Fund cease to be "eligible  securities" resulting in the net asset value
       ceasing to be $1 per share.  For example,  a guarantor on a security may
       fail to meet a contractual obligation.

   Q   How does the portfolio manager decide which securities to buy and sell?

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

For additional  information  about other securities in which we may invest each
Fund's assets, see APPENDIX A on page 29.

FUND MANAGEMENT

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

We provide management  services to the Fund pursuant to an Advisory  Agreement.
We are responsible for managing the Funds' portfolios  (including  placement of
brokerage  orders) and their  business  affairs,  subject to the  authority and
supervision  by the Board of Trustees.  For our  services,  the Funds pay us an
annual fee. This fee, which is accrued daily and paid monthly, is computed as a
percentage of the aggregate average net assets of both Funds combined. This fee
is allocated  between the Funds based on the  relative net assets of each.  The
fee is computed  at one-half of one percent  (.50%) of the first $50 million of
average net assets, two-fifths of one percent (.40%) of that portion of average
net assets over $50 million but not over $100 million,  and three-tenths of one
percent (.30%) of that portion of average net assets in excess of $100 million.
The  fee we  received  for  the  fiscal  year  ended  March  31,  1998,  net of
reimbursements,  was equal to .02% of average net assets for the Texas Tax-Free
Income Fund.  We waived the advisory  fee for the Texas  Tax-Free  Money Market
Fund.  We  reimbursed  the Texas  Tax-Free  Income  Fund  $73,971 and the Texas
Tax-Free Money Market Fund $47,657 for their Total Operating Expenses in excess
of the .50% limitation.  We also provide services related to selling the Funds'
shares and receive no compensation for those services.

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

USING MUTUAL FUNDS IN AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

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

                                      17
<PAGE>

II. Using Funds in an Investment Program

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

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.

For example,  assume you wish to pursue the higher yields usually  available in
the long-term bond market,  but you are also concerned about the possible price
swings of the long-term bonds.  You could divide your  investments  between the
Texas Tax-Free Income Fund and the Texas Tax-Free Money Market Fund. This would
create a portfolio  with a higher  yield than that of the money market and less
volatility  than that of the long-term  market.  This is just one way you could
combine funds to fit your own risk and reward goals.

III. USAA's Family of Funds

We offer you another  alternative  with our asset  strategy  funds listed under
asset allocation on page 32. These unique mutual funds provide a professionally
managed diversified investment portfolio within a mutual fund. Designed for the
individual  who  prefers  to  delegate  the  asset  allocation  process  to  an
investment manager, their structure achieves diversification across a number of
investment categories.

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

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT

You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required for new accounts.  However,  after you open your
initial  account  with us,  you will not need to fill out  another  application
unless the registration is different.

                                      18
<PAGE>

TAX ID NUMBER

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

EFFECTIVE DATE

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

MINIMUM INVESTMENTS

INITIAL PURCHASE

o    $3,000. Employees of USAA and its affiliated companies may open an account
     through  payroll  deduction  for as little as $25 per pay  period  with no
     initial investment.

ADDITIONAL PURCHASES

o    $50 (Except  transfers  from  brokerage  accounts into the Texas  Tax-Free
     Money Market Fund, which are exempt from the minimum).

     account, paycheck,  income-producing investment, or USAA money market fund
     account.  Sign up for these  services  when  opening  an  account  or call
     1-800-531-8448 to add these services.

PHONE  1-800-531-8448

o    If you have an existing  USAA account and would like to open a new account
     or  exchange  to another  USAA  fund,  call for  instructions.  To open an
     account by phone, the new account must have the same  registration as your
     existing account.

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day.

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

                                      20
<PAGE>

Redemptions are subject to income tax based on the  difference between the cost
of shares when purchased and the price received upon redemption.

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

HOW TO REDEEM

WRITTEN, FAX, TELEGRAPH, OR TELEPHONE

o    Send your written instructions to:
       USAA Shareholder Account Services
       9800 Fredericksburg Road
       San Antonio, TX 78288
o    Send  a  signed  fax  to  1-800-292-8177,  or  send  a  telegram  to  USAA
     Shareholder Account Services.
o    Call toll free 1-800-531-8448, in San Antonio, 456-7202.

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

CHECKWRITING

o    Checks can be issued for your Texas  Tax-Free  Money Market Fund  account.
     Return a signed signature card, which  accompanies  your  application,  or
     request a signature card separately and return to:
       USAA Shareholder Account Services
       9800 Fredericksburg Road
       San Antonio, TX 78288

You will not be charged for the use of checks or any subsequent reorders.  Your
checkwriting  privilege  is subject to State  Street  Bank and Trust  Company's
rules and regulations governing checking accounts.  You may write checks in the
amount of $250 or more.  Checks  written  for less  than $250 will be  returned
unpaid.  Because the value of your account  changes daily as dividends  accrue,
you may not write a check to close your account.

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
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

Beginning  in  September  1998,  and  occurring   annually   thereafter,   USAA
Shareholder  Account  Services (SAS),  the Funds' transfer agent,  may 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:

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

o   limit or discontinue the  offering of shares of any portfolio of  the Trust
    without notice to the shareholders;

o   impose a  redemption  charge of up to 1% of the net  asset  value of shares
    redeemed if circumstances indicate a charge is necessary for the protection
    of remaining  investors  (for  example,  if excessive  market-timing  share
    activity unfairly burdens  long-term  investors);  however,  this 1% charge
    will not be imposed upon  shareholders  unless  authorized  by the Board of
    Directors and the required notice has been given to shareholders;

o   require  a signature  guarantee  for  transactions or  changes  in  account
    information  in those  instances where  the appropriateness  of a signature
    authorization  is in  question.  The Statement  of  Additional  Information
    contains information on acceptable guarantors;

                                      22
<PAGE>

o   redeem an account with a total value of less than $500 of either Fund, with
    certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered in your state of  residence.  Only Texas  residents may exchange into a
Texas Fund. The Funds'  transfer  agent will  simultaneously  process  exchange
redemptions  and  purchases  at the  share  prices  next  determined  after the
exchange  order  is  received.  The  investment  minimums  applicable  to share
purchases also apply to exchanges. For federal income tax purposes, an exchange
between Funds is a taxable  event;  and as such, you may realize a capital gain
or loss.  Exchanges are based on the difference between the cost of shares when
purchased and the price received upon exchange.

The Funds have undertaken certain procedures  regarding telephone  transactions
as described on page 21.

Exchange Limitations, Excessive Trading

To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds).

Share Price Calculation

The price at which you  purchase  and  redeem  Fund  shares is equal to the net
asset value (NAV) per share determined on the effective date of the purchase or
redemption.  You may buy and sell Fund  shares  at the NAV per share  without a
sales  charge.  Each  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.

Securities  of the Texas  Tax-Free  Income Fund are valued each business day at
their current market value as determined by a pricing  service  approved by the
Trust's  Board of  Trustees.  Securities  which cannot be valued by the pricing
service, and all other  assets, are valued in good faith at fair value

                                      23
<PAGE>

using methods we have  determined under  the general  supervision  of the Board
of Trustees. In addition, securities with maturities of 60 days or less and all
securities  of the Texas  Tax-Free  Money  Market Fund are stated at  amortized
cost, which approximates market value.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Funds' Statement of Additional Information.

Dividends and Distributions

Net  investment  income  of each  Fund is  accrued  daily  and paid on the last
business day of the month.  Dividends shall begin accruing on shares  purchased
the day  following  the  effective  date and  shall  continue  to accrue to the
effective date of redemption.  Any net capital gain distribution usually occurs
within 45 days of the March 31 fiscal year end, which would be somewhere around
the middle of May. The Funds will make additional payments to shareholders,  if
necessary, to avoid the imposition of any federal income or excise tax.

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the  Fund  shares  computed  on the  ex-dividend  date.  Any
capital gain  distributions  paid by the Texas Tax-Free Income Fund will reduce
the  NAV per  share  by the  amount  of the  dividend  or  distribution.  These
dividends and distributions are subject to taxes. If you become a resident of a
state other than Texas,  we will mail a check for proceeds of income  dividends
to you monthly.  We will mail a check for any capital gain  distribution to you
after the distribution is paid.

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.  While we manage  the
Funds so that at least 80% of each  Fund's  annual  income  will be exempt from
federal  income  taxes,  we  may  invest  up to 20% of  the  Funds'  assets  in
securities that generate  income not exempt from federal income taxes.  Because
interest  income may be exempt for  federal  income tax  purposes,  it does not
necessarily  mean that the  interest  income may be exempt  under the income or
other tax laws of any state or local taxing authority.  As discussed earlier on
page 12, capital gains distributions by a Fund may be

                                      24
<PAGE>

taxable.  Note that the Taxpayer Relief  Act of 1997 and  regulations that will
likely be adopted to implement  the Act may affect  the status and treatment of
certain  distributions shareholders  receive  from  the Fund.  We urge  you  to
consult your own tax adviser about the status of distributions from the Fund in
your own state and locality.

WITHHOLDING  - Federal law requires each Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o   fails to furnish the Fund with a correct tax identification number,
o   underreports dividend or interest income, or
o   fails to certify that he or she is not subject to withholding.

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

REPORTING - Each Fund will report  information to you concerning the tax status
of  dividends  and  distributions  for federal  income tax  purposes  annually,
including  the  portion  of the  dividends  constituting  interest  on  private
activity  bonds and the  percentage  and source of  interest  income  earned on
tax-exempt securities held by the Fund during the preceding year.

Texas Taxation

Texas  does not  currently  impose an  income  tax on  individuals.  Therefore,
dividends and distributions  paid by the Funds to individuals who are residents
of Texas are not subject to a Texas  personal  income tax. If Texas  eventually
enacts a personal income tax, investors will need to consult with their own tax
advisors with respect to the possible taxation of dividends and distributions.

Texas imposes a franchise tax on  corporations,  limited  liability  companies,
certain banks,  limited banking  associations and savings and loan associations
that do  business  in the  State  or that are  chartered  or  authorized  to do
business in the State.  It is a tax on the privilege of doing  business  within
the State,  measured  by such an entity's  net  taxable  capital and by its net
taxable earned surplus.  Because the Funds are series of a registered  open-end
investment  company organized as a Delaware business trust, they themselves are
not subject to the Texas franchise tax. An investor in the Funds subject to the
Texas franchise tax, however,  must include  distributions it receives from the
Funds in its calculation of net taxable  capital.  All  distributions  from the
Funds that are exempt  from  federal  income tax,  though,  are exempt from the
portion of the Texas franchise tax based on taxable earned surplus.

Year 2000

Like  other  organizations  around  the  world,  the Funds  could be  adversely
affected if the computer systems used by the Funds, their service providers, or
companies  in which the Funds  invest do not  properly  process  and  calculate
date-related  information  beginning  on January 1,  2000,  a problem  commonly
referred to as the "Year 2000 Problem." We and our USAA  affiliates  have taken
steps to address any  potential  Year 2000 Problem  with the computer  programs
used by the Funds, us, and other USAA companies.  We expect USAA programs to be
fully  compliant  by some  time  during  the  first  half of 1999.  We are also
actively  reviewing the steps being taken by our third-party  service providers
as well as those of the Funds to address the Year 2000  Problem.  Those reviews
include site visits of the principal service providers.  At this time, however,
there can be no  assurance  that the  steps  being  taken by USAA,  third-party
service providers, or companies in which the Funds invest will be sufficient to
avoid adverse impact to the Funds for the Year 2000 Problem.

                                   APPENDIX A

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

VARIABLE RATE SECURITIES

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

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

In the case of the Texas  Tax-Free  Money Market Fund only,  any variable  rate
instrument  with a demand  feature  will be deemed to have a maturity  equal to
either  the date on which the  underlying  principal  amount  may be  recovered
through demand or the next rate  adjustment  date  consistent  with  applicable
regulatory requirements.

PUT BONDS

We may invest a Fund's assets 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.  For the Texas  Tax-Free  Income Fund,
maturity  for put  bonds is  deemed  to be the date on  which  the put  becomes
exercisable.  Generally,  maturity for put bonds for the Texas  Tax-Free  Money
Market Fund is determined as stated under Variable Rate Securities.

ZERO COUPON BONDS

We may invest a Fund's  assets 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,  each Fund records as income the
daily amortization of the purchase discount.

                                      29
<PAGE>

WHEN-ISSUED SECURITIES

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

o   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.
o   The Funds do not earn interest on the securities until settlement,  and the
    market  value  of  the  securities  may  fluctuate   between  purchase  and
    settlement.
o   Such securities can be sold before settlement date.

MUNICIPAL LEASE OBLIGATIONS

We may invest a Fund's assets in a variety of instruments  commonly referred to
as municipal lease obligations, including:

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

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.

LIQUIDITY

We may invest up to 15% of the net assets of the Texas  Tax-Free  Income Fund's
market value and up to 10% of the Texas  Tax-Free  Money Market  Fund's  market
value  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.

Lease obligations and certain put bonds subject to restrictions on transfer may
be determined to be liquid in accordance with the guidelines established by the
Funds' Board of Trustees.

In determining the liquidity of a lease obligation,  we will consider:  (1) the
frequency  of trades  and quotes  for the lease  obligation;  (2) the number of
dealers  willing to  purchase  or sell the lease  obligation  and the number of
other  potential  purchasers;  (3) dealer  undertakings to make a market in the
lease obligation;  (4) the nature of the marketplace trades, including the time
needed to dispose of the lease obligation, the method of soliciting offers, and
the mechanics of transfer;  (5) whether the lease  obligation is of a size that
will be attractive to institutional investors; (6) whether the lease obligation
contains a  non-appropriation  clause and the likelihood  that the obligor will
fail to make an  appropriation  therefor;  and (7) such  other  factors  as the
Manager may determine to be relevant to such determination.

In determining  the liquidity of put bonds with  restrictions  on transfer,  we
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 put bond.

                            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  investments  of the  FLORIDA  TAX-FREE  INCOME  FUND 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 sale 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 these securities based on methods which include  consideration
of yields or prices of tax-exempt  securities of  comparable  quality,  coupon,
maturity and type,  indications  as to values from dealers in  securities,  and
general market conditions.  Securities  purchased with maturities of 60 days or
less are stated at amortized cost which approximates  market value.  Repurchase
agreements  are  valued  at cost.  Securities  which  cannot  be  valued by the
Service,  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.

     The value of the FLORIDA TAX-FREE MONEY MARKET FUND'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 Fund would receive upon
the sale of the instrument.

     The  valuation  of the Florida  Tax-Free  Money  Market  Fund'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
Florida  Tax-Free  Money  Market  Fund's  price per share,  as computed for the
purpose of sales and  redemptions,  at $1. There can be no assurance,  however,
that the Fund  will at all  times be able to  maintain  a  constant  $1 NAV per
share. Such procedures  include review of the Fund's holdings at such intervals
as is deemed  appropriate  to determine  whether the Fund's NAV  calculated  by
using  available  market  quotations  deviates  from $1 per share  and,  if so,
whether such deviation may result in material  dilution or is otherwise  unfair
to  existing  shareholders.  In the  event  that it is  determined  that such a
deviation exists,  the Board of Trustees will take such corrective action as it
regards  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 canceled due to  nonpayment or if the Trust
does not receive good funds either by check or electronic funds transfer,  USAA
Shareholder  Account Services (Transfer Agent) will treat the cancellation as a
redemption of shares  purchased,  and you will be responsible for any resulting
loss  incurred  by the  Fund  or the  Manager.  If you are a  shareholder,  the
Transfer Agent can redeem shares from your account(s) as reimbursement  for all
losses.  In addition,  you may be prohibited  or restricted  from making future
purchases  in any of the USAA  Family of Funds.  A $15 fee is  charged  for all
returned items, including checks and electronic funds transfers.

TRANSFER OF SHARES

You may transfer Fund shares to another person by sending written  instructions
to the Transfer  Agent.  The account must be clearly  identified,  and you must
include  the  number  of  shares  to be  transferred,  the  signatures  of  all
registered owners, and all stock certificates, if any, which are the subject of
transfer.  You

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

     The Board of Trustees may cause the  redemption of an account with a total
value of less than $500 provided (1) the value of the account has been reduced,
for reasons other than market action,  below the minimum initial  investment in
such Fund at the time of the establishment of the account,  (2) the account has
remained below the minimum level for six months, and (3) 60 days' prior written
notice of the proposed redemption has been sent to you. Shares will be redeemed
at the NAV on the date fixed for  redemption  by the Board of Trustees.  Prompt
payment will be made by mail to your last known address.
    
     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 Florida  Tax-Free Money Market Fund may request that checks
be issued  for their  account.  Checks  must be  written in amounts of at least
$250.

     Checks issued to  shareholders of the Fund 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.  You will  continue  to earn  dividends  until the  shares are
redeemed by the presentation of a check.

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

     The  checkwriting   privilege  is  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 you for the use
of the checks or for subsequent reorders of checks.

     The Trust  reserves  the right to assess a  processing  fee  against  your
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.
   
     You may  request  that the  Transfer  Agent stop  payment on a check.  The
Transfer Agent will use its best efforts to execute stop payment  instructions,
but does not guarantee that such efforts will be effective.  The Transfer Agent
will charge you $10 for each stop payment you request.
    
                                INVESTMENT PLANS
   
The Trust makes available the following investment plans to shareholders of the
Funds. At the time you sign up for any of the following  investment  plans that
utilize the electronic funds transfer service, you will

                                       3
<PAGE>
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

INVESTRONIC(R) - The regular purchase of additional  shares through  electronic
funds transfer from a checking or savings account.  You may invest as little as
$50 per month.
   
DIRECT PURCHASE  SERVICE - The periodic  purchase of shares through  electronic
funds  transfer from an employer  (including  government  allotments and social
security), an income-producing  investment,  or an account with a participating
financial institution.
    
AUTOMATIC  PURCHASE  PLAN - The  periodic  transfer  of funds from a USAA money
market fund to purchase  shares in another  non-money  market USAA mutual fund.
There is a minimum investment  required for this program of $5,000 in the money
market fund, with a monthly transaction minimum of $50.
   
BUY/SELL  SERVICE - The  intermittent  purchase or redemption of shares through
electronic  funds  transfer to or from a checking or savings  account.  You may
initiate a "buy" or "sell" whenever you choose.

DIRECTED  DIVIDENDS  - If you own  shares  in more than one of the Funds in the
USAA  Family of Funds,  you may  direct  that  dividends  and/or  capital  gain
distributions  earned in one fund be used to purchase shares  automatically  in
another fund.

     Participation in these  systematic  purchase plans allows you to engage in
dollar-cost  averaging.  For additional  information concerning the benefits of
dollar-cost averaging, see APPENDIX C.
    
SYSTEMATIC WITHDRAWAL PLAN
   
If you own shares having a NAV of $5,000 or more in a single investment account
(accounts in different  Funds cannot be aggregated for this  purpose),  you may
request  that enough  shares to produce a fixed  amount of money be  liquidated
from the account monthly or quarterly. The amount of each withdrawal must be at
least $50. Using the electronic funds transfer service,  you may choose to have
withdrawals   electronically   deposited  at  your  bank  or  other   financial
institution. You may also elect to have checks mailed to a designated address.

     This plan may be initiated by depositing shares worth at least $5,000 with
the Transfer Agent and by completing a Systematic  Withdrawal Plan application,
which may be requested from the Manager. You may terminate participation in the
plan at any time.  You are not charged  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 you select at the time the plan is established.  Withdrawal  payments made
under this plan may exceed  dividends  and  distributions  and, to this extent,
will  involve the use of  principal  and could  reduce the dollar value of your
investment  and  eventually  exhaust the  account.  Reinvesting  dividends  and
distributions  helps  replenish  the  account.  Because  share  values  and net
investment income can fluctuate, you should not expect withdrawals to be offset
by rising income or share value gains.

     Each  redemption  of shares  may  result in a gain or loss,  which must be
reported  on your  income tax  return.  Therefore,  you should keep an accurate
record of any gain or loss on each withdrawal.
    
                              INVESTMENT POLICIES
   
The  section  captioned  FUND  INVESTMENTS  in  the  Prospectus  describes  the
fundamental  investment  objectives and the investment  policies  applicable to
each Fund, and the following is provided as additional information.
    
CALCULATION OF PORTFOLIO WEIGHTED AVERAGE MATURITIES
   
Weighted  average  maturity  is  derived  by  multiplying  the  value  of  each
investment by the number of days remaining to its maturity,  adding the results
of these  calculations,  and then dividing the total by the value of the Fund's
portfolio.  An obligation's  maturity is typically determined on a stated final
maturity basis, although there are some exceptions to this rule.
    
     With respect to obligations  held by the Florida  Tax-Free Income Fund, if
it is  probable  that the  issuer of an  instrument  will take  advantage  of a
maturity-shortening device, such as a call, refunding, or redemption provision,
the date on which the instrument will probably be called, refunded, or redeemed
may be considered to be its maturity  date.  Also, the 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 life of these  securities  is likely to be  substantially  shorter than
their stated final maturity.

                                       4
<PAGE>
In addition, for purposes of the Fund's investment policies, an instrument will
be treated as having a maturity  earlier than its stated  maturity  date if the
instrument has technical features such as puts or demand features which, in the
judgment of the  Manager,  will result in the  instrument  being  valued in the
market as though it has the earlier maturity.

The Florida  Tax-Free  Money  Market  Fund will  determine  the  maturity of an
obligation in its portfolio in accordance  with Rule 2a-7 under the  Investment
Company Act of 1940, as amended (1940 Act).

REPURCHASE AGREEMENTS

Each Fund may invest up to 5% of its net  assets in  repurchase  agreements.  A
repurchase  agreement is a transaction  in which a security is purchased with a
simultaneous  commitment  to sell the security back to the seller (a commercial
bank or recognized securities dealer) at an agreed upon price on an agreed upon
date,  usually not more than seven days from the date of  purchase.  The resale
price  reflects the purchase  price plus an agreed upon market rate of interest
which is unrelated to the coupon rate or maturity of the purchased security.  A
repurchase  agreement  involves the  obligation of the seller to pay the agreed
upon  price,  which  obligation  is in  effect  secured  by  the  value  of the
underlying security. In these transactions,  the securities purchased by a Fund
will have a total value  equal to or in excess of the amount of the  repurchase
obligation and will be held by the Funds' custodian until  repurchased.  If the
seller defaults and the value of the underlying  security declines,  a Fund may
incur a loss and may incur  expenses in selling the  collateral.  If the seller
seeks relief under the bankruptcy  laws, the  disposition of the collateral may
be delayed or limited. Any investments in repurchase  agreements will give rise
to income which will not qualify as  tax-exempt  income when  distributed  by a
Fund.
   
WHEN-ISSUED SECURITIES

Each  Fund may  invest in new  issues of  tax-exempt  securities  offered  on a
when-issued  basis;  that is, 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 Funds do 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.

     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, the Fund will
meet its obligations  from then available cash, sale of segregated  securities,
sale of other securities, or sale of the when-issued securities themselves.

MUNICIPAL LEASE OBLIGATIONS

Each  Fund may  invest in  municipal  lease  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.  In  evaluating  a  potential  investment  in  such  a  lease
obligation,  the Manager will consider:  (1) the credit quality of the obligor,
(2) whether the underlying  property is essential to a  governmental  function,
and (3) whether the lease obligation contains covenants prohibiting the obligor
from substituting  similar property if the obligor fails to make appropriations
for the lease obligation.

TEMPORARY DEFENSIVE POLICY

Each Fund may on a temporary basis because of market,  economic,  political, or
other  conditions,  or other  conditions  invest  up to 100% of its  assets  in
short-term securities whether or not they are exempt from federal income taxes.
Such taxable securities may consist of obligations of the U.S. Government,  its
agencies  or  instrumentalities,  and  repurchase  agreements  secured  by such
instruments; certificates of deposit of domestic banks having capital, surplus,
and  undivided  profits  in excess of $100  million;  banker's  acceptances  of
similar banks; commercial paper; and other corporate debt obligations.
    
OTHER POLICIES

Each Fund may lend its  securities  and engage in short sells  against the box.
The Florida Tax-Free Income Fund may also invest in options,  financial futures
contracts,  and options on financial futures contracts.  However,  the Funds do
not intend to engage in any of these  practices  during the coming year without
first supplying further information in the Prospectus.

<PAGE>
                            INVESTMENT RESTRICTIONS
   
The following  investment  restrictions have been adopted by the Trust for each
Fund. These restrictions may not be changed for any given Fund without approval
by the lesser of (1) 67% or more of the voting securities  present at a meeting
of the Fund if more than 50% of the outstanding  voting  securities of the Fund
are  present  or  represented  by  proxy or (2)  more  than  50% of the  Fund's
outstanding voting securities.  The investment  restrictions of one Fund may be
changed without affecting those of the other Fund.
    
Under the restrictions, neither Fund will:

 (1)  with respect to 75% of its total assets,  purchase the  securities of any
      issuer (except Government Securities, as such term is defined in the 1940
      Act) if, as a result, the Fund would own more than 10% of the outstanding
      voting  securities  of such issuer or the Fund would have more than 5% of
      the value of its total assets  invested in the securities of such issuer;
      for purposes of this limitation,  identification  of the "issuer" will be
      based on a determination  of the source of assets and revenues  committed
      to meeting interest and principal payments of each security; for purposes
      of this limitation the State of Florida or other  jurisdictions  and each
      of  its  separate  political  subdivisions,   agencies,  authorities  and
      instrumentalities shall be treated as a separate issuer;

 (2)  borrow  money,  except  that a Fund may  borrow  money for  temporary  or
      emergency purposes in an amount not exceeding 33 1/3% of its total assets
      (including the amount borrowed) less liabilities (other than borrowings),
      nor will either Fund purchase securities when its borrowings exceed 5% of
      its total assets;

 (3)  purchase  any  securities  which  would cause 25% or more of the value of
      that Fund's total  assets at the time of such  purchase to be invested in
      securities  the interest  upon which is derived from revenues or projects
      with similar  characteristics,  such as toll road revenue bonds,  housing
      revenue  bonds,  electric power project  revenue bonds,  or in industrial
      revenue bonds which are based,  directly or indirectly,  on the credit of
      private  entities  of any  one  industry;  provided  that  the  foregoing
      limitation  does not apply with respect to investments  in U.S.  Treasury
      Bills, other obligations issued or guaranteed by the U.S. Government, its
      agencies and instrumentalities,  and, in the case of the Florida Tax-Free
      Money Market Fund,  certificates  of deposit and banker's  acceptances of
      domestic banks;

 (4)  issue senior securities, except as permitted under the 1940 Act;

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

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

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

 (8)  purchase or sell  commodities  or commodities  contracts  except that the
      Florida Tax-Free Income Fund may invest in financial  futures  contracts,
      options thereon, and similar instruments.
   
ADDITIONAL RESTRICTION

The following  restriction is not considered to be a fundamental  policy of the
Funds.  The Board of Trustees may change this  additional  restriction  without
notice to or approval by the shareholders.
    
Neither Fund will:
   
 (1)  The  Florida  Tax-Free  Income  Fund may not invest  more than 15% of the
      value of its net assets and the Florida  Tax-Free  Money  Market Fund may
      not  invest  more  than 10% of the value of its net  assets  in  illiquid
      securities  (including  repurchase agreements maturing in more than seven
      days).
    
                          SPECIAL RISK CONSIDERATIONS

The information set forth below is derived from official statements prepared in
connection with the issuance of bonds of the State of Florida (the "State") and
other sources that are generally  available to investors.  The  information  is
provided  as  general  information  intended  to  give a brief  and  historical
description and is not intended to indicate future or continuing  trends in the
financial  or other  positions  of the  State or of  local  governmental  units
located  in  the  State.  The  Trust  has  not   independently   verified  this
information.
   
     THE FLORIDA ECONOMY.  Throughout the 1980s, the State's unemployment rate,
generally,  tracked below that of the nation.  In the  nineties,  the trend was
reversed,  until  1995 and 1996,  where the  State's  unemployment  rate  again
tracked below the U.S. The State's  unemployment  rate for 1997 was 4.8%, while
the  national  average  was 4.9%.  The  State's  unemployment  rate for 1998 is
projected to be 4.8%, while the national average is also projected to be 4.8%.

                                       6
<PAGE>
     Personal  income in the State has been  growing  strongly the last several
years  and has  generally  outperformed  both  the  nation  as a whole  and the
Southeast in particular.  The reasons for this are twofold:  first, the State's
population has expanded at a very strong pace; and second,  the State's economy
since the early seventies has diversified in such a way as to provide a broader
economic  base.  From 1985 through 1995,  the State's per capita income rose an
average of 5.0% per year,  while the  national per capita  income  increased an
average of 4.9%.  For 1996,  the  State's  per capita  personal  income rose an
average of 4.7% while the national  per capita  personal  income rose 4.5%.  In
1996, per capita personal income in Florida was $24,104, while the national per
capita personal income was $24,231. The structure of the State's income differs
from  that  of  the  nation  and  the  Southeast.   Because  the  State  has  a
proportionately greater retirement age population,  property income (dividends,
interest and rent) and transfer payments (social security and pension benefits,
among  other  sources of income)  are a  relatively  more  important  source of
income. For example,  Florida's employment income in 1996, represented 59.6% of
total personal income, while the nation's share of total personal income in the
form of wages and  salaries  and  other  labor  benefits  was  70.2%.  Transfer
payments,  such as social  security,  are  occasionally  subject to legislative
change.

     The State's  strong  population  growth is one main reason why its economy
has typically  performed  better than the nation as a whole. In 1980, the State
was ranked seventh among the 50 states with a population of 9.7 million people.
The State has continued to grow since then and as of April 1, 1997 ranks fourth
with an estimated  population of 14.7 million.  Since 1990, the State's average
annual rate of population  increase has been  approximately 1.8% as compared to
an approximately  1.0% average annual increase for the nation as a whole. While
annual growth in the State's population is expected to decline somewhat,  it is
still  expected to grow  approximately  230,000 per year  throughout the 1990s,
however, no assurance can be given that such growth will continue.

     Tourism is one of the State's most important industries.  Approximately 47
million people visited the State in 1997, as reported by the Florida Department
of  Commerce.  By the  end of this  fiscal  year,  49.7  million  domestic  and
international  tourists  are  expected to have  visited  this State.  The State
expects 50.6 million  visitors in 1999-2000.  The State's tourism appears to be
recovering  from the  effects of negative  publicity  regarding  crime  against
tourists in the State.

     The  State  has  a  dynamic   construction   industry,   with  single  and
multi-family  housing starts  accounting for  approximately  9.2% of total U.S.
housing  starts in 1997,  while  the  State's  population  was only 5.5% of the
nation's total population.  The reason for such a dynamic construction industry
was the rapid  growth of the  State's  population.  Since 1985,  total  housing
starts have averaged  approximately 148,000 per year. Total housing starts were
132,813 in 1997, and are projected to be 127,400 in 1998-99.
    
     The  Florida  economy is  expected  to grow at a moderate  pace,  but will
continue to outperform the U.S. as a whole.  An important  element of Florida's
economic outlook is the construction sector. Multi-family starts have been slow
to  recover in the State from the early  90's  recession,  but are now  showing
stronger  growth.  Overall,  the Florida economy appears to be in line with the
U.S.  economy and is expected to experience  steady growth over the next couple
of years.
   
     FLORIDA  REVENUES  AND  EXPENDITURES.  Financial  operations  of the State
covering all receipts and expenditures  are maintained  through the use of four
funds--General  Revenue Fund, Trust Funds,  Working Capital Fund and the Budget
Stabilization Fund. In fiscal year 1995-96, the State derived approximately 66%
of its total direct revenues to these funds from State taxes and fees.  Federal
funds and other special revenues  accounted for the remaining  revenues.  Major
sources of tax revenues to the General  Revenue Fund are the sales and use tax,
corporate  income tax,  intangible  personal  property  tax,  beverage tax, and
estate tax, which amounted to 68%, 8%, 4%, 3%, and 3%,  respectively,  of total
General Revenue Fund receipts.  State  expenditures  are categorized for budget
and appropriation purposes by type of fund and spending unit, which are further
subdivided  by line  item.  In fiscal  year  1996-97,  appropriations  from the
General  Revenue  Fund for  education,  health and welfare,  and public  safety
amounted to  approximately  53%, 26% and 14%,  respectively,  of total  General
Revenues.

     The   estimated   General   Revenue  plus   Working   Capital  and  Budget
Stabilization  funds  available  to the State for  fiscal  year  1997-98  total
$18,150.9  million,  an 8.5%  increase  over  1996-97.  Compared  to  effective
appropriations   from  General   Revenues  plus  Working   Capital  and  Budget
Stabilization funds for fiscal year 1997-98 of $17,114 million, this results in
unencumbered  reserves  estimated at $1,036.9 million at the end of fiscal year
1996-97. Estimated fiscal year 1998-99 General Revenue plus Working Capital and
Budget  Stabilization  funds available total $18,644  million,  a 2.7% increase
over fiscal year 1997-98.

     The sales and use tax is the greatest single source of tax receipts in the
State. For the State fiscal year ended June 30, 1997, receipts from this source
were $12,089 million, an increase of 5.5% from fiscal year 1996-97.  The second
largest  source of State tax receipts is the Motor Fuel Tax.  Preliminary  data
show  collections  from this source in State  fiscal year ending June 30, 1997,
were $2,012  million.  However,  these revenues are almost  entirely  dedicated
trust funds for specific  purposes  and are not  included in the State  General
Revenue Fund.  Alcoholic  beverage tax revenues totalled $447.2 million for the
State  fiscal year ending June 30, 1997.  The receipts of corporate  income tax
for the fiscal year ended June 30, 1997

                                       7
<PAGE>
were  $1,362.3  million,  an increase of 17.2% from the  previous  fiscal year.
Gross Receipt tax collections for fiscal year 1996-97  totalled $575.7 million,
an  increase  of 6% over  the  previous  fiscal  year.  Documentary  stamp  tax
collections totalled $844.2 million during fiscal year 1996-97, increasing 8.9%
from the previous fiscal year. The intangible personal property tax is a tax on
stocks,  bonds,  notes,  governmental  leaseholds,  certain limited partnership
interests,  mortgages and other obligations secured by liens on Florida realty,
and other  intangible  personal  property.  Total  collections  from intangible
personal  property taxes were $952.4 million during fiscal year ending June 30,
1997, a 6.3% increase from the previous  fiscal year.  Severance taxes totalled
$77.2 million  during fiscal year  1995-96,  up 26.1% from the previous  fiscal
year.  In November,  1986,  the voters of the State  approved a  constitutional
amendment to allow the State to operate a lottery. Fiscal year 1996-97 produced
ticket sales of $2.09 billion of which education received  approximately $792.3
million.
    
     The State  Constitution  does not permit a state or local personal  income
tax. An  amendment  to the State  Constitution  by the electors of the State is
required to impose a personal income tax in the State.

     Since January 1, 1994,  property  valuations  for homestead  property have
been  subject to a growth cap.  Growth in the just  (market)  value of property
qualifying  for the  homestead  exemption is limited to 3% or the change in the
Consumer Price Index,  whichever is less. If the property changes  ownership or
homestead  status,  it is to be  re-valued  at full just  value on the next tax
roll.  Although the impact of the growth cap cannot be determined,  it may have
the  effect  of  causing  local  government  units in the State to rely more on
non-ad  valorem  revenues to meet  operating  and other  requirements  normally
funded with ad valorem tax revenues.

     An amendment to the State Constitution was approved by statewide ballot in
the November 8, 1994,  general  election  which is commonly  referred to as the
"Limitation on State Revenues  Amendment."  This amendment  provides that State
revenues  collected  for any fiscal  year  shall be  limited to State  revenues
allowed under the  amendment  for the prior fiscal year plus an adjustment  for
growth.  Growth is defined as an amount  equal to the  average  annual  rate of
growth in State personal  income over the most recent twenty quarters times the
State  revenues  allowed under the  amendment for the prior fiscal year.  State
revenues  collected  for any  fiscal  year in  excess  of this  limitation  are
required  to be  transferred  to the Budget  Stabilization  Fund until the fund
reaches the maximum  balance  specified in Section  19(g) of Article III of the
State  Constitution,  and thereafter is required to be refunded to taxpayers as
provided  by general  law.  The  limitation  on State  revenues  imposed by the
amendment  may be increased by the  Legislature,  by a two-thirds  vote of each
house.

     The term "State  revenues," as used in the amendment,  means taxes,  fees,
licenses,  and charges for services  imposed by the Legislature on individuals,
businesses,  or agencies  outside State  government.  However,  the term "State
revenues"  does  not  include:  (1)  revenues  that are  necessary  to meet the
requirements  set forth in documents  authorizing  the issuance of bonds by the
State;  (2) revenues  that are used to provide  matching  funds for the federal
Medicaid  program with the exception of the revenues used to support the Public
Medical  Assistance Trust Fund or its successor  program and with the exception
of State  matching  funds used to fund elective  expansions  made after July 1,
1994; (3) proceeds from the State lottery  returned as prizes;  (4) receipts of
the Florida Hurricane Catastrophe Fund; (5) balances carried forward from prior
fiscal years;  (6) taxes,  licenses,  fees and charges for services  imposed by
local,  regional,  or school  district  governing  bodies;  or (7) revenue from
taxes,  licenses,  fees and charges for services  required to be imposed by any
amendment  or  revision  to the State  Constitution  after  July 1,  1994.  The
amendment  took effect on January 1, 1995,  and was first  applicable  to State
fiscal year 1995-96.

     It  should be noted  that  many of the  provisions  of the  amendment  are
ambiguous,  and likely will not be  clarified  until State courts have ruled on
their meanings.  Further,  it is unclear how the Legislature will implement the
language of the amendment and whether such implementing legislation itself will
be the subject of further court interpretation.

     The Fund cannot predict the impact of the amendment on State finances.  To
the extent local  governments  traditionally  receive  revenues  from the State
which are subject to, and limited by, the amendment, the future distribution of
such State revenues may be adversely affected by the amendment.

     According  to the Office of the  Comptroller,  Department  of Banking  and
Finance of the State,  as of February 21, 1996, the State maintains a high bond
rating from Moody's  Investors  Service (Aa2),  Standard & Poor's Ratings Group
(AA+), and Fitch Investors Service,  Inc. (AA) on all of its general obligation
bonds.  Such ratings may be revised and  downgraded  at any time by such rating
agencies. Outstanding general obligation bonds at June 30, 1996 totalled almost
$7.4 billion and were issued to finance capital outlay for educational projects
of both local school districts and state universities, environmental protection
and highway  construction.  The State has issued  over $805  million of general
obligation bonds since July 1, 1996.

                             PORTFOLIO TRANSACTIONS

The  Manager,  pursuant to the  Advisory  Agreement  dated June 25,  1993,  and
subject to the general  control of the Trust's  Board of  Trustees,  places all
orders  for  the  purchase  and  sale  of Fund  securities.  Purchases

                                       8
<PAGE>
of Fund securities are made either directly from the issuer or from dealers who
deal in tax-exempt  securities.  The Manager may sell Fund securities  prior to
maturity  if  circumstances  warrant  and if it believes  such  disposition  is
advisable. In connection with portfolio transactions for the Trust, the Manager
seeks to obtain the best available net price and most  favorable  execution for
its orders.  The Manager has no agreement or commitment  to place  transactions
with any broker-dealer and no regular formula is used to allocate orders to any
broker-dealer.  However,  the Manager may place security orders with brokers or
dealers who furnish  research or other services to the Manager as long as there
is no sacrifice in obtaining the best overall terms available. Payment for such
services  would be generated  only  through  purchase of new issue fixed income
securities.

     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.  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.

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

PORTFOLIO TURNOVER RATE

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.

     The rate of  portfolio  turnover  will not be a limiting  factor  when the
Manager  deems  changes  in  the  Florida   Tax-Free  Income  Fund's  portfolio
appropriate in view of its investment objective. For example, securities may be
sold in anticipation of a rise in interest rates (market  decline) or purchased
in anticipation of a decline in interest rates (market rise) and later sold. In
addition, a security may be sold and another security of comparable quality may
be purchased at approximately  the same time in order to take advantage of what
the Fund believes to be a temporary  disparity in the normal yield relationship
between the two securities.  These yield  disparities may occur for reasons not
directly related to the investment  quality of particular issues or the general
movement of interest rates, such as changes in the overall demand for or supply
of various types of tax-exempt securities.

     For the last two fiscal years the Florida Tax-Free Income Fund's portfolio
turnover rates were as follows:
   
             1997 . . . . . 44.75%          1998 . . . . . 27.48%
    
     Portfolio  turnover  rates  have  been  calculated   excluding  short-term
variable rate securities,  which are those with put date intervals of less than
one year.
   
                             DESCRIPTION OF SHARES

The Funds are series of the Trust and are diversified. The Trust is an open-end
management investment company established as a business trust under the laws of
the State of Delaware pursuant to a Master Trust Agreement dated June 21, 1993.
The Trust is  authorized  to issue  shares of  beneficial  interest in separate
portfolios.  Four  such  portfolios  have  been  established,  two of which are
described in this SAI. Under the Master Trust Agreement,  the Board of Trustees
is  authorized to create new  portfolios in addition to those already  existing
without shareholder approval.
    
                                       9
<PAGE>
     Each  Fund's  assets  and all  income,  earnings,  profits,  and  proceeds
thereof, subject only to the rights of creditors, are specifically allocated to
such Fund. They constitute the underlying  assets of each Fund, are required to
be segregated on the books of account,  and are to be charged with the expenses
of such Fund.  Any general  expenses of the Trust not readily  identifiable  as
belonging  to a  particular  Fund are  allocated  on the  basis  of the  Funds'
relative net assets during the fiscal year or in such other manner as the Board
determines  to be fair and  equitable.  Each share of each Fund  represents  an
equal  proportionate  interest  in that  Fund  with  every  other  share and is
entitled to dividends and distributions out of the net income and capital gains
belonging to that Fund when declared by the Board.
   
     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. The Trust 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.  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.
The Trust will assist in communicating to other shareholders about the meeting.
On any matter submitted to the  shareholders,  the holder of each Fund share is
entitled  to one vote per  share  (with  proportionate  voting  for  fractional
shares)  regardless  of the  relative  net asset  values of the Funds'  shares.
However,  on matters  affecting  an  individual  Fund,  a separate  vote of the
shareholders of that Fund is required.  Shareholders of a Fund are not entitled
to vote on any  matter  which does not  affect  that Fund but which  requires a
separate vote of another Fund.  Shares do not have  cumulative  voting  rights,
which means that holders of more than 50% of the shares voting for the election
of Trustees can elect 100% of the Trust's Board of Trustees, and the holders of
less than 50% of the shares  voting for the  election of  Trustees  will not be
able to elect any person as a Trustee.
    
     Shareholders of a particular Fund might have the power to elect all of the
Trustees of the Trust because that Fund has a majority of the total outstanding
shares of the  Trust.  When  issued,  each  Fund's  shares  are fully  paid and
nonassessable,  have no  pre-emptive  or  subscription  rights,  and are  fully
transferable. There are no conversion rights.

                   CERTAIN FEDERAL INCOME 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) and (2) satisfy certain diversification
requirements  at the  close  of  each  quarter  of  the  Fund's  taxable  year.
Furthermore,  to pay tax-exempt interest income dividends,  at least 50% of the
value of each Fund's  total  assets at the close of each quarter of its taxable
year must consist of  obligations  the interest of which is exempt from federal
income tax. Each 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
this excise tax.
   
     For federal income tax purposes,  debt  securities  purchased by the Funds
may be treated as having  original  issue  discount.  Original  issue  discount
represents interest income for federal income tax purposes and can generally be
defined as the  excess of the stated  redemption  price at  maturity  of a debt
obligation over the issue price. Original issue discount is treated for federal
income  tax  purposes  as earned by the  Funds,  whether  or not any  income is
actually received, and therefore is subject to the distribution requirements of
the  Code.  However,   original  issue  discount  with  respect  to  tax-exempt
obligations generally will be excluded from the Funds' taxable income, although
such  discount  will be included in gross  income for  purposes of the 90% test
described  previously.  Original  issue  discount  with  respect to  tax-exempt
securities  is accrued and added to the adjusted  tax basis of such  securities
for purposes of determining  gain or loss upon sale or at maturity.  Generally,
the amount of original  issue discount is

                                      10
<PAGE>
determined  on the basis of a  constant  yield to  maturity  which  takes  into
account the compounding of accrued  interest.  An investment in a stripped bond
or stripped coupon will result in original issue discount.
    
     Debt securities may be purchased by the Funds at a market discount. Market
discount  occurs when a security is purchased at a price less than the original
issue price  adjusted for accrued  original issue  discount,  if any. The Funds
intend to defer  recognition of accrued market discount until maturity or other
disposition  of the bond. For securities  purchased at a market  discount,  the
gain realized on disposition  will be treated as taxable ordinary income to the
extent it does not exceed accrued market discount on the bond.

     The Funds may also  purchase  debt  securities  at a premium,  i.e.,  at a
purchase price in excess of face amount. With respect to tax-exempt securities,
the premium must be amortized to the maturity  date but no deduction is allowed
for the premium amortization. The amortized bond premium will reduce the Funds'
adjusted tax basis in the securities.  For taxable securities,  the premium may
be amortized if the Funds so elect. The amortized premium on taxable securities
is first offset against interest received on the securities and then allowed as
a deduction,  and, for  securities  issued after  September  27, 1985,  must be
amortized under an economic accrual method.

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.  It is expected that none of the Funds'
distributions will qualify for the corporate dividends-received deduction.

     To the extent that a Fund's  dividends  distributed  to  shareholders  are
derived from interest  income exempt from federal income tax and are designated
as  "exempt-interest  dividends"  by a Fund,  they  will be  excludable  from a
shareholder's  gross income for federal income tax purposes.  Shareholders  who
are recipients of Social Security benefits should be aware that exempt-interest
dividends received from a 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.

     All  distributions of investment income during the year will have the same
percentage designated as tax-exempt.  This method is called the "average annual
method."  Since  the Funds  invest  primarily  in  tax-exempt  securities,  the
percentage will be substantially  the same as the amount actually earned during
any particular distribution period.

     A shareholder of the Florida  Tax-Free  Income Fund should be aware that a
redemption  of shares  (including  any  exchange  into  another USAA Fund) is a
taxable event and, accordingly,  a capital gain or loss may be recognized. 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 redemption or
exchange  will be disallowed  to the extent of such  exempt-interest  dividend.
Similarly,  if a  shareholder  of the Fund receives a  distribution  taxable as
long-term  capital  gain with  respect  to shares  of the Fund and  redeems  or
exchanges shares before he has held them for more than six months,  any loss on
the  redemption or exchange (not  otherwise  disallowed as  attributable  to an
exempt-interest dividend) will be treated as long-term capital loss.

     The Funds 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 the AMT and the  amount  of any tax to be  paid.  For
corporate investors,  alternative minimum taxable income is increased by 75% of
the amount by which adjusted current earnings (ACE) exceeds alternative minimum
taxable  income  before  the  ACE  adjustment.  For  corporate  taxpayers,  all
tax-exempt  interest is considered in  calculating  the AMT as part of the ACE.
Prospective investors should consult their own tax advisers with respect to the
possible application of the AMT to their tax situation.

     Opinions  relating  to the  validity  of  tax-exempt  securities  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 Funds'
counsel makes any review of the basis of such opinions.

                                FLORIDA TAXATION

TAXATION OF THE FUNDS

If the Funds have tax nexus with Florida,  such as through the location  within
Florida of the Trust or Funds' activities or those of their advisers,  then the
Florida Funds will be subject to Florida corporate income tax. In

                                      11
<PAGE>
addition, if the Funds' intangible assets have a taxable situs in Florida, then
the Funds will be subject to Florida's  intangible  personal  property tax. The
Funds intend to operate so as not to be subject to Florida taxation.

TAXATION OF THE SHAREHOLDERS

Florida  does not  impose an income tax on  individuals.  Thus,  dividends  and
distributions paid by the Funds to individuals who are residents of Florida are
not  taxable by  Florida.  Florida  imposes an income tax on  corporations  and
similar entities at a rate of 5.5%.  Dividends and  distributions of investment
income and capital gains by the Funds will be subject to the Florida  corporate
income tax.  Accordingly,  investors in the Funds,  including,  in  particular,
investors  that may be subject to the  Florida  corporate  income  tax,  should
consult  their tax  advisers  with  respect to the  application  of the Florida
corporate income tax to the receipt of Fund dividends and  distributions and to
the investor's Florida tax situation in general.

     Florida  imposes a tax on intangible  personal  property  owned by Florida
residents.  Shares in the Funds  constitute  intangible  personal  property for
purposes of the Florida  intangible  personal  property  tax.  Thus,  unless an
exemption  applies,  shares  in the  Funds  will  be  subject  to  the  Florida
intangible  personal  property tax. Florida provides an exemption for shares in
an investment fund if the Fund's  portfolio of assets consists solely of assets
exempt from the Florida  intangible  personal  property tax. Assets exempt from
the Florida intangible  personal property tax include obligations issued by the
State of Florida and its  political  subdivisions,  municipalities,  and public
authorities;  obligations  of the U.S.  Government,  its agencies,  and certain
territories and possessions such as Puerto Rico, the Virgin Islands,  and Guam;
and cash.
   
     The Funds  received a ruling from the Florida  Department  of Revenue that
if, on the last  business  day of any  calendar  year,  the Funds'  investments
consist solely of assets exempt from the Florida  intangible  personal property
tax,  shares of the Funds  owned by Florida  residents  will be exempt from the
Florida  intangible  personal  property tax in the following year. If shares of
the Funds are subject to the Florida intangible  personal property tax, because
less than 100% of the Funds'  assets on the last  business  day of the calendar
year consist of assets  exempt from the Florida  intangible  personal  property
tax,  only the portion of the NAV of a share of the Funds that is  attributable
to obligations of the U.S. Government will be exempt from taxation.

The Board of Trustees of the Trust consists of seven Trustees who supervise the
business affairs of the Trust. Set forth below are the Trustees and officers of

(b)  At March 31, 1998, the USAA Family of Funds  consisted of four  registered
     investment  companies offering 35 individual funds. Each Trustee presently
     serves as a Trustee or  Director  of each  investment  company in the USAA
     Family of Funds.  In addition,  Michael J.C.  Roth  presently  serves as a
     Trustee of USAA Life  Investment  Trust, a registered  investment  company
     advised by IMCO, consisting of seven funds offered to investors in a fixed
     and variable annuity contract with USAA Life Insurance  Company.  Mr. Roth
     receives no compensation as Trustee of USAA Life Investment Trust.

     All of the above Trustees are also  Trustees/Directors  of the other funds
within the USAA  Family of Funds.  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  reimburses  certain  expenses of the Trustees who are not
affiliated with the investment  adviser. As of April 30, 1998, 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.

     The Trust knows of no one person who, as of April 30, 1998, held of record
or owned beneficially 5% or more of either Fund's shares.
    

                              THE TRUST'S MANAGER
   
As described  in the  Prospectus,  USAA  Investment  Management  Company is the
Manager  and  investment   adviser,   providing  services  under  the  Advisory
Agreement.  The Manager, an affiliate of United Services Automobile Association
(USAA), a large,  diversified financial services institution,  was organized in
May 1970 and has served as investment  adviser and  underwriter  for USAA State
Tax-Free 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
Investment  Trust, USAA Mutual Fund, Inc., USAA Tax Exempt Fund, Inc., 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,  the Trust has agreed to pay the
Manager a fee computed as described  under FUND  MANAGEMENT in the  Prospectus.
Management fees are computed and accrued daily and 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 (if any); expenses of issuance and redemption of shares;
charges of transfer agents, custodians, and dividend disbursing agents; cost 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  persons  (not  affiliated)  of the  Manager;  costs of printing and
mailing the Prospectus, SAI, and periodic reports to existing shareholders; and
any other  charges or fees not  specifically  enumerated.  The Manager pays the
cost of printing and mailing copies of the Prospectus,  the SAI, and reports to
prospective shareholders.
   
     The Advisory Agreement will remain in effect until June 30, 1999, 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 in 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. Any such waiver or reimbursement  may be terminated by the Manager at any
time without prior notice to shareholders.  The Manager has voluntarily  agreed
to limit each Fund's expenses to .50% of its ANA until August 1, 1999, and will
reimburse the Funds for all expenses in excess of the limitations.

     For the last three fiscal years, management fees were as follows:
   
                                             1996         1997         1998

     Florida Tax-Free Income Fund          $239,649     $322,603     $437,613
     Florida Tax-Free Money Market Fund    $256,697     $301,693     $323,098
    
     Because the Funds'  expenses  exceeded  the  Manager's  voluntary  expense
limitation,  the Manager did not receive management fees to which it would have
been entitled as follows:
   
                                              1996        1997         1998

     Florida Tax-Free Money Market Fund     $85,352     $56,434      $20,954
    
UNDERWRITER

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

TRANSFER AGENT

The  Transfer  Agent  performs  transfer  agent  services for the Trust under a
Transfer Agency Agreement.  Services include maintenance of shareholder account
records,  handling of communications  with  shareholders,  distribution of Fund
dividends,  and  production  of reports  with  respect to account  activity for
shareholders  and the  Trust.  For  its  services  under  the  Transfer  Agency
Agreement,  each Fund pays the  Transfer  Agent an annual  fixed fee of $26 per
account. The fee is subject to change at any time.

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

CUSTODIAN

                        CALCULATION OF PERFORMANCE DATA
   
Information  regarding  total  return and yield of each Fund is provided  under
COULD THE VALUE OF YOUR INVESTMENT IN THESE FUNDS FLUCTUATE? in the Prospectus.
See VALUATION OF SECURITIES herein for a discussion of the manner in which each
Fund's price per share is calculated.
    
TOTAL RETURN

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

                                P(1 + T)n = ERV

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

     The  calculation  assumes all 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.

<PAGE>
   
The date of commencement of operations for the Florida Tax-Free Income Fund was
October 1, 1993.  The Fund's  average  annual total  returns for the  following
periods ended March 31, 1998, were:

         1 year . . . . 12.22%      Since inception . . . . 5.34%
    
YIELD

The Florida Tax-Free Income Fund may advertise performance in terms of a 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[((a-b)/(cd)+1)^6-1]

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

     For purposes of the yield  calculation,  interest income is computed based
on the yield to maturity of each debt  obligation  in the Fund's  portfolio and
all recurring charges are recognized.
   
     The Fund's 30-day yield for the period ended March 31, 1998, was 4.75%.
    
YIELD - FLORIDA TAX-FREE MONEY MARKET FUND
   
When the Florida Tax-Free Money Market Fund 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 and income other
than  investment  income,  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
Fund'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 Fund'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 March 31, 1998, was 3.30%.
       Effective Yield for 7-day Period ended March 31, 1998, was 3.35%.
    
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. The Florida Money Market Fund may advertise performance in terms of a tax
equivalent  yield based on the 7-day yield or  effective  yield and the Florida
Income  Fund may  advertise  performance  in terms of a 30-day  tax  equivalent
yield.

     To calculate a tax equivalent  yield,  the Florida  investor must know his
Effective  Marginal Tax Rate or EMTR.  Assuming an investor  can fully  itemize
deductions on his or her federal tax return, the EMTR is the sum of the federal
marginal  tax rate and the Florida  Intangibles  Personal  Property  Tax effect
adjusted to reflect  the  deductibility  of the  Intangibles  Tax from  federal
income tax.

     The  computation  of the  Florida  intangible  tax effect is a  multi-step
process.  Since the  intangible  tax is a tax upon assets,  and not income,  an
investor may reduce his intangibles tax liability by choosing  investments that
are exempt from the Florida  Intangibles  Tax. We have  provided a table in the
Prospectus  to  estimate  the  effect  the  intangibles  tax may  have  upon an
investor's EMTR. The Florida  Intangibles  Property Tax effect is determined by
the investor's filing status, individual or joint, and the fair market value of
intangible assets subject to the intangibles tax. The formula is:

  Florida Intangible Tax Effect = Intangible Tax Liability / Intangible Assets

                                      17
<PAGE>
     The  formula  for  computing  the  EMTR  to  compare  with  fully  taxable
securities subject to both federal income and Florida intangible taxes is:

                      EMTR = Federal Marginal Tax Rate +
        [Florida Intangible Tax Effect x (1-Federal Marginal Tax Rate)]

     The tax equivalent yield is then computed by dividing the tax-exempt yield
of a fund by the complement of the EMTR.  The  complement,  for example,  of an
EMTR of 36.08% is 63.92%, that is (1.00-0.3608= 0.6392).

   Tax Equivalent Yield = Tax Exempt Yield / (1-Effective Marginal Tax Rate)
   
     Based on a  federal  marginal  tax rate of 36% and  intangible  assets  of
$300,000 filing  jointly,  the tax equivalent  yields for the Florida  Tax-Free
Income and Florida  Tax-Free  Money Market Funds for the period ended March 31,
1998 were 7.43% and 5.16%, respectively.
    

              APPENDIX A - TAX-EXEMPT SECURITIES AND THEIR RATINGS

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 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 IBCA, Inc. (Fitch),  Duff & Phelps Inc., and
Thompson  BankWatch,  Inc.  represent  their  opinions  of the  quality  of the
securities rated by them. 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.

I.  LONG-TERM DEBT RATINGS:

MOODY'S INVESTOR SERVICES, INC.
    
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 risk appear somewhat larger than in Aaa securities.

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

                                      18
<PAGE>
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:  MOODY'S APPLIES  NUMERICAL  MODIFIERS 1, 2, AND 3 IN EACH GENERIC RATING
CLASSIFICATION.  THE  MODIFIER 1  INDICATES  THAT THE  OBLIGATION  RANKS IN THE
HIGHER END OF ITS GENERIC RATING CATEGORY, THE MODIFIER 2 INDICATES A MID-RANGE
RANKING,  AND THE  MODIFIER  3  INDICATES  A  RANKING  IN THE LOWER END OF THAT
GENERIC RATING CATEGORY.

STANDARD & POOR'S RATINGS GROUP

AAA      An obligation  rated AAA has the highest rating assigned by Standard &
         Poor's. The obligor's capacity to meet its financial commitment on the
         obligation is EXTREMELY STRONG.

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

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

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

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

FITCH IBCA, INC.

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

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

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

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

PLUS 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, INC.

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

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

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

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

2. SHORT-TERM DEBT RATINGS:

MOODY'S STATE AND TAX-EXEMPT NOTES

MIG-1/VMIG1       This  designation  denotes  best  quality.  There is  present
                  strong   protection  by  established  cash  flows,   superior
                  liquidity support or demonstrated  broad-based  access to the
                  market for refinancing.

MIG-2/VMIG2       This designation denotes high quality.  Margins of protection
                  are ample although not so large as in the preceding group.

                                      19
<PAGE>
MOODY'S COMMERCIAL PAPER

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

           o Leading market positions in well-established industries.

           o High rates of return on funds employed.

           o Conservative  capitalization  structures with moderate reliance on
             debt and ample asset protection.

           o Broad margins in earning  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  promissory  obligations.
           This will normally be evidenced by many of the characteristics cited
           above but to a lesser degree.  Earnings trends and coverage  ratios,
           while  sound,  may be  more  subject  to  variation.  Capitalization
           characteristics,  while still  appropriate,  may be more affected by
           external conditions. Ample alternate liquidity is maintained.

S&P TAX-EXEMPT NOTES

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

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

S&P COMMERCIAL PAPER

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

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

FITCH'S COMMERCIAL PAPER, CERTIFICATES OF DEPOSIT AND TAX-EXEMPT NOTES

F1       Highest credit  quality.  Indicates the strongest  capacity for timely
         payment of financial commitments;  may have an added "+" to denote any
         exceptionally strong credit features.

F2       Good credit  quality.  A  satisfactory  capacity for timely payment of
         financial commitments,  but the margin of safety is not as great as in
         the case of the higher ratings.

F3       Fair credit  quality.  The  capacity  for timely  payment of financial
         commitments  is adequate;  however,  near-term  adverse  changes could
         result in a reduction to non-investment grade.

DUFF & PHELPS COMMERCIAL PAPER

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.

THOMPSON BANKWATCH, INC.

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

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

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

                       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.

                            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 investments of the TEXAS TAX-FREE INCOME FUND 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 sale
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 these securities based on methods which include  consideration of yields
or prices of tax-exempt securities of comparable quality,  coupon, maturity and
type,  indications as to values from dealers in securities,  and general market
conditions.  Securities purchased with maturities of 60 days or less are stated
at amortized cost which approximates  market value.  Repurchase  agreements are
valued at cost. Securities which cannot be valued by the Service, 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.

     The value of the TEXAS TAX-FREE  MONEY MARKET FUND'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 Fund would receive upon
the sale of the instrument.

     The  valuation  of  the  Texas  Tax-Free  Money  Market  Fund'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
Texas Tax-Free Money Market Fund's price per share, as computed for the purpose
of sales and redemptions,  at $1. There can be no assurance,  however, that the
Fund will at all times be able to  maintain a constant  $1 NAV per share.  Such
procedures include review of the Fund's holdings at such intervals as is deemed
appropriate to determine  whether the Fund's NAV calculated by using  available
market quotations deviates from $1 per share and, if so, whether such deviation
may  result  in  material   dilution  or  is   otherwise   unfair  to  existing
shareholders.  In the event that it is determined that such a deviation exists,
the Board of Trustees will take such corrective  action as it regards 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 canceled due to  nonpayment or if the Trust
does not receive good funds either by check or electronic funds transfer,  USAA
Shareholder  Account Services (Transfer Agent) will treat the cancellation as a
redemption of shares  purchased,  and you will be responsible for any resulting
loss  incurred  by the  Fund  or the  Manager.  If you are a  shareholder,  the
Transfer Agent can redeem shares from your account(s) as reimbursement  for all
losses.  In addition,  you may be prohibited  or restricted  from making future
purchases  in any of the USAA  Family of Funds.  A $15 fee is  charged  for all
returned items, including checks and electronic funds transfers.

TRANSFER OF SHARES

You may transfer Fund shares to another person by sending written  instructions
to the Transfer  Agent.  The account must be clearly  identified,  and you must
include  the  number  of  shares  to be  transferred,  the  signatures  of  all
registered owners, and all stock certificates, if any, which are the subject of
transfer.  You also need to send written  instructions signed by all registered
owners and supporting documents to change

                                       2
<PAGE>
an account registration due to events such as divorce, marriage, or death. If a
new  account  needs  to  be  established,  you  must  complete  and  return  an
application to the Transfer Agent.
    
             ADDITIONAL INFORMATION REGARDING REDEMPTION OF SHARES
   
The value of your investment at the time of redemption may be more or less than
the cost at  purchase,  depending on the value of the  securities  held in each
Fund's  portfolio.  Requests  for  redemption  which are subject to any special
conditions,  or which specify an effective date other than as provided  herein,
cannot be accepted. A gain or loss for tax purposes may be realized on the sale
of shares,  depending upon the price when  redeemed.

     The Board of Trustees may cause the  redemption of an account with a total
value of less than $500 provided (1) the value of the account has been reduced,
for reasons other than market action,  below the minimum initial  investment in
such Fund at the time of the establishment of the account,  (2) the account has
remained below the minimum level for six months, and (3) 60 days' prior written
notice of the proposed redemption has been sent to you. Shares will be redeemed
at the NAV on the date fixed for  redemption  by the Board of Trustees.  Prompt
payment will be made by mail to your last known address.
    
     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 Texas Tax-Free Money Market Fund may request that checks be
issued for their account. Checks must be written in amounts of at least $250.

     Checks issued to  shareholders of the Fund 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.  You will  continue  to earn  dividends  until the  shares are
redeemed by the presentation of a check.

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

     The  checkwriting   privilege  is  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 you for the use
of the checks or for subsequent reorders of checks.

     The Trust  reserves  the right to assess a  processing  fee  against  your
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.
   
     You may  request  that the  Transfer  Agent stop  payment on a check.  The
Transfer Agent will use its best efforts to execute stop payment  instructions,
but does not guarantee that such efforts will be effective.  The Transfer Agent
will charge you $10 for each stop payment you request.
    
                                INVESTMENT PLANS
   
The Trust makes available the following investment plans to shareholders of 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

                                       3
<PAGE>
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

INVESTRONIC(R) - The regular purchase of additional  shares through  electronic
funds transfer from a checking or savings account.  You may invest as little as
$50 per  month.
   
DIRECT PURCHASE  SERVICE - The periodic  purchase of shares through  electronic
funds  transfer from an employer  (including  government  allotments and social
security), an income-producing  investment,  or an account with a participating
financial institution.
    
AUTOMATIC  PURCHASE  PLAN - The  periodic  transfer  of funds from a USAA money
market fund to purchase  shares in another  non-money  market USAA mutual fund.
There is a minimum investment  required for this program of $5,000 in the money
market fund, with a monthly transaction minimum of $50.
   
BUY/SELL  SERVICE - The  intermittent  purchase or redemption of shares through
electronic  funds  transfer to or from a checking or savings  account.  You may
initiate a "buy" or "sell" whenever you choose.

DIRECTED  DIVIDENDS  - If you own  shares  in more than one of the Funds in the
USAA  Family of Funds,  you may  direct  that  dividends  and/or  capital  gain
distributions  earned in one fund be used to purchase shares  automatically  in
another fund.

     Participation in these  systematic  purchase plans allows you to engage in
dollar-cost  averaging.  For additional  information concerning the benefits of
dollar-cost averaging, see APPENDIX C.
    
SYSTEMATIC WITHDRAWAL PLAN
   
If you own shares having a NAV of $5,000 or more in a single investment account
(accounts in different  Funds cannot be aggregated for this  purpose),  you may
request  that enough  shares to produce a fixed  amount of money be  liquidated
from the account monthly or quarterly. The amount of each withdrawal must be at
least $50. Using the electronic funds transfer service,  you may choose to have
withdrawals   electronically   deposited  at  your  bank  or  other   financial
institution. You may also elect to have checks mailed to a designated address.

     This plan may be initiated by depositing shares worth at least $5,000 with
the  Transfer  Agent  and  by  completing  the   Systematic   Withdrawal   Plan
application,  which  may be  requested  from  the  Manager.  You may  terminate
participation  in the plan at any time.  You are not  charged  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 you select at the time the plan is established.  Withdrawal  payments made
under this plan may exceed  dividends  and  distributions  and, to this extent,
will  involve the use of  principal  and could  reduce the dollar value of your
investment  and  eventually  exhaust the  account.  Reinvesting  dividends  and
distributions  helps  replenish  the  account.  Because  share  values  and net
investment income can fluctuate, you should not expect withdrawals to be offset
by rising income or share value gains.

     Each  redemption  of shares  may  result in a gain or loss,  which must be
reported  on your  income tax  return.  Therefore,  you should keep an accurate
record of any gain or loss on each withdrawal.
    
                              INVESTMENT POLICIES
   
The  section  captioned  FUND  INVESTMENTS  in  the  Prospectus  describes  the
fundamental  investment  objectives and the investment  policies  applicable to
each Fund, and the following is provided as additional information.
    
CALCULATION OF PORTFOLIO WEIGHTED AVERAGE  MATURITIES
   
Weighted  average  maturity  is  derived  by  multiplying  the  value  of  each
investment by the number of days remaining to its maturity,  adding the results
of these  calculations,  and then dividing the total by the value of the Fund's
portfolio.  An obligation's  maturity is typically determined on a stated final
maturity basis, although there are some exceptions to this rule.
    
     With respect to obligations  held by the Texas Tax-Free Income Fund, if it
is  probable  that  the  issuer  of an  instrument  will  take  advantage  of a
maturity-shortening device, such as a call, refunding, or redemption provision,
the date on which the instrument will probably be called, refunded, or redeemed
may be considered to be its maturity  date.  Also, the 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 life of these  securities  is likely to be  substantially  shorter than
their stated final maturity. In addition, for purposes of the Fund's investment
policies, an instrument will be treated as having a

                                       4
<PAGE>
maturity  earlier than its stated maturity date if the instrument has technical
features such as puts or demand features which, in the judgment of the Manager,
will result in the  instrument  being valued in the market as though it has the
earlier maturity.

     The Texas  Tax-Free  Money Market Fund will  determine  the maturity of an
obligation in its portfolio in accordance  with Rule 2a-7 under the  Investment
Company Act of 1940, as amended (1940 Act).

REPURCHASE  AGREEMENTS

Each Fund may invest up to 5% of its net  assets in  repurchase  agreements.  A
repurchase  agreement is a transaction  in which a security is purchased with a
simultaneous  commitment  to sell the security back to the seller (a commercial
bank or recognized securities dealer) at an agreed upon price on an agreed upon
date,  usually not more than seven days from the date of  purchase.  The resale
price  reflects the purchase  price plus an agreed upon market rate of interest
which is unrelated to the coupon rate or maturity of the purchased security.  A
repurchase  agreement  involves the  obligation of the seller to pay the agreed
upon  price,  which  obligation  is in  effect  secured  by  the  value  of the
underlying security. In these transactions,  the securities purchased by a Fund
will have a total value  equal to or in excess of the amount of the  repurchase
obligation and will be held by the Funds' custodian until  repurchased.  If the
seller defaults and the value of the underlying  security declines,  a Fund may
incur a loss and may incur  expenses in selling the  collateral.  If the seller
seeks relief under the bankruptcy  laws, the  disposition of the collateral may
be delayed or limited. Any investments in repurchase  agreements will give rise
to income which will not qualify as  tax-exempt  income when  distributed  by a
Fund.
   
WHEN-ISSUED SECURITIES

Each  Fund may  invest in new  issues of  tax-exempt  securities  offered  on a
when-issued  basis;  that is, 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 Funds do 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.

     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, the Fund will
meet its obligations  from then available cash, sale of segregated  securities,
sale of other  securities,  or sale of the when-issued  securities  themselves.

MUNICIPAL LEASE OBLIGATIONS

Each  Fund may  invest in  municipal  lease  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.  In  evaluating  a  potential  investment  in  such  a  lease
obligation,  the Manager will consider:  (1) the credit quality of the obligor,
(2) whether the underlying  property is essential to a  governmental  function,
and (3) whether the lease obligation contains covenants prohibiting the obligor
from substituting  similar property if the obligor fails to make appropriations
for the  lease  obligation.

TEMPORARY  DEFENSIVE  POLICY

Each Fund may on a temporary basis because of market,  economic,  political, or
other  conditions,  or other  conditions  invest  up to 100% of its  assets  in
short-term securities whether or not they are exempt from federal income taxes.
Such taxable securities may consist of obligations of the U.S. Government,  its
agencies  or  instrumentalities,  and  repurchase  agreements  secured  by such
instruments; certificates of deposit of domestic banks having capital, surplus,
and  undivided  profits  in excess of $100  million;  banker's  acceptances  of
similar banks; commercial paper; and other corporate debt obligations.
    
OTHER POLICIES

Each Fund may lend its  securities  and engage in short sells  against the box.
The Texas Tax-Free  Income Fund may also invest in options,  financial  futures
contracts,  and options on financial futures contracts.  However,  the Funds do
not intend to engage in any of these  practices  during the coming year without
first supplying further information in the Prospectus.

                            INVESTMENT RESTRICTIONS
   
The following  investment  restrictions have been adopted by the Trust for each
Fund. These restrictions may not be changed for any given Fund without approval
by the lesser of (1) 67% or more of the voting securities  present at a meeting
of the Fund if more than 50% of the outstanding  voting  securities of the Fund
are  present  or  represented  by  proxy or (2)  more  than  50% of the  Fund's
outstanding voting securities.  The investment  restrictions of one Fund may be
changed without affecting those of the other Fund.

Under the restrictions, neither Fund will:
    
 (1)  with respect to 75% of its total assets,  purchase the  securities of any
      issuer (except Government Securities, as such term is defined in the 1940
      Act) if, as a result, the Fund would own more than 10% of the outstanding
      voting  securities  of such issuer or the Fund would have more than 5% of
      the value of its total assets  invested in the securities of such issuer;
      for purposes of this limitation,  identification  of the "issuer" will be
      based on a determination  of the source of assets and revenues  committed
      to meeting interest and principal payments of each security; for purposes
      of this limitation the State of Texas or other  jurisdictions and each of
      its  separate   political   subdivisions,   agencies,   authorities   and
      instrumentalities shall be treated as a separate issuer;

 (2)  borrow  money,  except  that a Fund may  borrow  money for  temporary  or
      emergency purposes in an amount not exceeding 33 1/3% of its total assets
      (including the amount borrowed) less liabilities (other than borrowings),
      nor will either Fund purchase securities when its borrowings exceed 5% of
      its total assets;

 (3)  purchase  any  securities  which  would cause 25% or more of the value of
      that Fund's total  assets at the time of such  purchase to be invested in
      securities  the interest  upon which is derived from revenues or projects
      with similar  characteristics,  such as toll road revenue bonds,  housing
      revenue  bonds,  electric power project  revenue bonds,  or in industrial
      revenue bonds which are based,  directly or indirectly,  on the credit of
      private  entities  of any  one  industry;  provided  that  the  foregoing
      limitation  does not apply with respect to investments  in U.S.  Treasury
      Bills, other obligations issued or guaranteed by the U.S. Government, its
      agencies and  instrumentalities,  and, in the case of the Texas  Tax-Free
      Money Market Fund,  certificates  of deposit and banker's  acceptances of
      domestic banks;

 (4)  issue senior securities, except as permitted under the 1940 Act;

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

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

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

 (8)  purchase or sell  commodities  or commodities  contracts  except that the
      Texas  Tax-Free  Income Fund may invest in financial  futures  contracts,
      options thereon, and similar instruments.
   
ADDITIONAL RESTRICTION

The following  restriction is not considered to be a fundamental  policy of the
Funds.  The Board of Trustees may change this  additional  restriction  without
notice to or approval by the shareholders.
    
Neither Fund will:
   
 (1)  The Texas Tax-Free  Income Fund may not invest more than 15% of the value
      of its net assets and the Texas Tax-Free Money Market Fund may not invest
      more  than 10% of the  value of its net  assets  in  illiquid  securities
      (including repurchase agreements maturing in more than seven days).
    
                          SPECIAL RISK CONSIDERATIONS
   
The following only highlights some of the more significant financial trends and
budget  information  affecting  the State of Texas,  and is based  solely  upon
information drawn from official statements and prospectuses relating to various
securities offerings by the State of Texas, its agencies and instrumentalities,
as  available on the date of this SAI. The Funds have made no attempt to verify
the accuracy or  completeness  of this  information  or the absence of material
adverse  changes  occurring  subsequent  to the date of such  information.  The
historical  data and trends  discussed  in this  section are not intended to be
exhaustive  or to predict  future  events or trends.  There can be no assurance
that past  trends  will  continue  or that there will be an absence of material
adverse changes subsequent to the date of this SAI.

     LACK  OF  DIVERSIFICATION.  Because  the  Texas  Funds  concentrate  their
investments in a specific state,  there are risks associated with investment in
the Funds  which  would not exist if the Funds'  investments  were more  widely
diversified.  These risks include the possible  enactment of new legislation in
the State

                                       6
<PAGE>
which could affect State and/or municipal  obligations,  economic factors which
could affect  these  obligations,  and varying  levels of supply and demand for
state and municipal obligations.

     STATE DEBT.  Except as  specifically  authorized,  the Texas  Constitution
generally prohibits the creation of debt by or on behalf of the State, with two
exceptions:  (i) debt created to supply  deficiencies  in revenues which do not
total more than $200,000 at any time, and (ii) debt to repel invasion, suppress
insurrection,  defend the State in war, or pay existing debt. In addition,  the
Texas  Constitution  prohibits the  Legislature  from lending the credit of the
State to any person,  including  municipalities,  or pledging the credit of the
State in any  manner  for the  payment of the  liabilities  of any  individual,
association of individuals, corporation or municipality. The limitations of the
Constitution  do not  prohibit the issuance of revenue  bonds,  however,  since
Texas  courts  (like  the  courts  of  most  states)  have  held  that  certain
obligations do not create a "debt" within the meaning of the Constitution.  The
State of Texas and various  State  agencies  have issued  revenue bonds payable
from the  revenues  produced  by  various  facilities  or from  lease  payments
appropriated by the  Legislature.  Furthermore,  obligations  which are payable
from funds  expected to be available  during the current  budget  period do not
constitute  "debt" within the meaning of the  Constitution.  Certain short term
obligations,  like the Tax and Revenue  Anticipation  Notes issued by the Texas
Comptroller of Public Accounts,  which mature within the biennial budget period
in which they are issued (discussed below in more detail), are not deemed to be
"debt" within the meaning of the Texas Constitution.

     Voters  in  Texas  have  from  time to time  by  constitutional  amendment
authorized the issuance of general  obligation  indebtedness for which the full
faith,  credit and taxing  power of the State are pledged.  In some cases,  the
authorized  indebtedness  may  not  be  issued  without  the  approval  of  the
Legislature,   but  in  other  cases,   the   constitutional   amendments   are
self-operating and the debt may be issued without specific legislative action.

     Various State  agencies  have the  authority to issue  general  obligation
bonds. The Veterans' Land Board is authorized to issue general obligation bonds
to finance  the  purchase  of land and  housing by  veterans.  The Texas  Water
Development Board (the "TWDB") is authorized to issue general  obligation bonds
to make funds available to municipalities  and certain other governmental units
for the conservation  and development of water  resources;  the acquisition and
development  of water  storage  facilities  for the  filtration,  treatment and
transportation  of water;  water quality  enhancement  purposes;  flood control
purposes;  and water-efficient  irrigation systems.  Additionally,  the TWDB is
authorized to incur unlimited contractual  obligations to the United States for
the  acquisition  and  development  of water  storage  facilities in reservoirs
constructed  by the  United  States.  These  obligations  are  declared  by the
Constitution to be general obligations of the State. On November 4, 1997, Texas
voters  decided to allow the TWDB to  consolidate  existing,  specific  general
obligation  authority for separate  purposes in order to more  effectively meet
demand experienced for such purposes.

     The Texas  Agricultural  Finance  Authority  (the "TAFA") is authorized to
issue  general  obligation  bonds  to  provide  financial  assistance  for  the
expansion,  development  and  diversification  of  production,  processing  and
marketing of Texas agricultural products.  Additionally, the TAFA is authorized
to issue  general  obligation  bonds  for a farm  and  ranch  land  acquisition
program.  The Texas Parks and Wildlife Department (the "TPWD") is authorized to
issue general  obligation  bonds to finance the  acquisition and development of
State parks.  The Texas Higher  Education  Coordinating  Board is authorized to
issue general  obligation  bonds to finance  student loans.  The Texas National
Research  Laboratory  Commission  (the "TNRLC") was authorized to issue general
obligation  bonds  to aid in the  construction  of the  "superconducting  super
collider" project. Given the decision by the U.S. Congress to terminate federal
funding for the super collider, the Legislature made provisions for the removal
of the remaining bond  authority.  Elimination of the remaining  super collider
general  obligation  authority  required voter approval,  which was received in
November 1995.  Additionally,  the General  Appropriations  Act for the 1998-99
biennium  includes  provisions  for the  defeasance  of all or a portion of the
outstanding  general  obligation  bonds  associated  with  the  super  collider
project.

     The Texas Public  Finance  Authority  (the "TPFA") is  authorized to issue
general obligation bonds to finance the acquisition, construction and equipping
of new  facilities,  and major repair or renovation of existing  facilities for
correction institutions and mental health and mental retardation  institutions.
Effective January 1, 1992, TPFA is authorized to issue general obligation bonds
on  behalf  of the  TNRLC  and the  TPWD.  The  Texas  Department  of  Economic
Development,  formerly the Texas Department of Commerce, is authorized to issue
general obligation bonds to provide loans to finance the  commercialization  of
new or improved  products or processes  developed in Texas and to stimulate the
development  of  small  businesses  in  Texas.   Certain  public  colleges  and
universities are authorized to issue bonds payable from certain  appropriations
required by the Constitution, without limitation as to principal amount, except
that the debt  service  on such  bonds may not  exceed 50 percent of the amount
appropriated each year.
    
     Credit  ratings on State debt are  dependent  upon  several  economic  and
political  factors,  including  the ability to  continue to fund a  substantial
portion of the debt  service  on  general  obligation  debt from  general  fund
revenue in the annual  State  budget and the ability to maintain  the amount of
authorized debt within the range of affordability.

     OUTSTANDING  DEBT  SUMMARY.  Texas  had a total  of  approximately  $11.67
billion in State bonds  outstanding  on August 31, 1997, up from $11.34 billion
on August 31, 1996.  This figure  includes  commercial  paper and variable rate
notes;  however, it does not include short-term debt issued for cash management
purposes  (described below).  Approximately $4.95 billion of Texas' total state
debt outstanding on August 31, 1997,  carries the general  obligation pledge of
the State.  These  bonds  carry a  constitutional  pledge of the full faith and
credit of the State to pay off the bonds if program revenues are  insufficient.
General  obligation  debt is the only legally  binding  debt of the State.  The
issuance of general  obligation  bonds  requires  passage of a  proposition  by
two-thirds of both houses of the Texas  Legislature  and by a majority of Texas
voters. The remaining debt,  non-general  obligation debt, is dependent only on
the  revenue  stream  of a  particular  program  or an  appropriation  from the
Legislature. General obligation and non-general obligation bonds that depend on
general  revenue for debt service are classified as "not  self-supporting"  for
purposes of this disclosure.  Bonds that are not self-supporting  depend solely
on the State's  general  revenue fund for debt service,  drawing funds from the
same  source  used  by the  Legislature  to  finance  the  operation  of  state
government.  "Not  self-supporting"  bonds outstanding totaled approximately $3
billion of total State bonds  outstanding  as of the end of August  1997.  Debt
service on  "self-supporting"  bonds (both general  obligation and  non-general
obligation bonds) is paid from sources outside the State's general revenue fund
or outside State government entirely.  Self-supporting bonds, therefore, do not
put direct pressure on State finances.

     During fiscal 1997,  State agencies and  institutions of higher  education
issued $1.03 billion in bonds, including $758.8 million in new money bonds (not
including  commercial  paper) and $269.4 million in refunding  bonds. New money
bond issues raise  additional  funds and add to the State's  outstanding  debt,
while refunding bonds, generally,  replace bonds issued previously. Texas State
agencies and institutions of higher education plan to issue  approximately $2.2
billion in bonds and commercial  paper during fiscal year 1998. Of this amount,
$676  million is  anticipated  to be not  self-supporting.  Approximately  $1.9
billion will be issued to finance projects or programs and  approximately  $311
million will be issued to refund existing debt.

     As of August 31, 1997, Texas had approximately  $5.4 billion in authorized
but  unissued  bonds.  Approximately  $3.4  billion  or  62  percent  of  these
authorized but unissued  bonds would be State general  obligation  debt.  About
$721  million or 3 percent of the total  authorized  but  unissued  bonds would
require the payment of debt service from general  revenue.  The  remainder  are
designed to be self-supporting through program revenues.

     GENERAL  OBLIGATION DEBT. Much of the outstanding  bonded  indebtedness of
the State is  designed  to be  self-supporting,  even though the full faith and
credit of the State is pledged for its payment.  Revenues from land and housing
programs are expected to be  sufficient  to pay  principal  and interest on all
outstanding Veterans Land Board bonds. Almost all of the bonded indebtedness of
the TWDB is self-supporting to the extent that all funds provided from payments
on obligations of political subdivisions for water projects are applied to such
bonded indebtedness in an effort to avoid resorting to appropriated funds; such
revenues  have been  sufficient to pay the principal and interest on such bonds
since  fiscal year 1980.  The  remaining  portion of the TWDB's debt is for the
Economically Distressed Areas Program. These bonds do not depend totally on the
State's  general  revenue for debt service;  however,  up to  approximately  90
percent of the bonds issued may be used for grants. Revenues from student loans
are pledged to pay the principal and interest on the  outstanding  bonds of the
Texas Higher Education Coordinating Board. Revenues from park entrance fees and
sporting goods sales tax have been  sufficient to pay principal and interest on
the outstanding bonds of the TPWD.

     The general obligation bonds that have been issued by the TPFA, other than
TPWD bonds,  are not  self-supporting.  All debt service on these bonds is paid
from the State's  general  revenue fund.  The higher  education  constitutional
bonds are not  explicitly a general  obligation  or full faith and credit bond,
but the revenue pledge has the same effect. Debt service is paid from an annual
constitutional appropriation to qualified institutions of higher education from
the  first  monies  coming  into the  State  treasury  that  are not  otherwise
dedicated by the Constitution.

     STATE REVENUE BONDS. The TPFA and the Military Facilities  Commission (the
"MFC"),  formerly known as the National  Guard Armory Board,  have authority to
issue  State-backed  lease revenue  bonds.  Such  obligations do not constitute
"debt"  within the  meaning of the  Constitution,  even though they are payable
from rental payments  appropriated  and made by the State under leases covering
the  facilities  financed  with the  proceeds  of the  obligations.  The MFC is
authorized to issue bonds,  payable  solely from rents received with respect to
buildings constructed by it and leased to the National Guard without limitation
as to amount. Effective January 1, 1992, the TPFA issues bonds on behalf of the
MFC.

     The TNRLC had the authority to issue  State-backed  lease  revenue  bonds,
however,  on June 1, 1995,  all of these  outstanding  bonds  issued to provide
funding  for the super  collider  project  were  defeased  or  redeemed.  As of
September  1, 1995,  the Texas  Legislature  rescinded  the  TNRLC's  remaining
revenue bond authority.

                                       8
<PAGE>
     The TPFA is  authorized to issue both  lease-revenue  bonds to finance the
construction, acquisition or renovation of State office buildings and equipment
revenue bonds to finance the  acquisition of equipment.  For the  lease-revenue
bonds,  the authorized  amount of debt is equal to 1.5 times the estimated cost
of projects that have been approved by the Legislature.  Effective September 1,
1997, TPFA is also authorized to issue park development revenue bonds on behalf
of the TPWD.

     In addition to the foregoing revenue obligations issued by State entities,
additional  State  programs  may be  financed  with  revenue  bonds or  similar
obligations   payable  from  revenues  generated  by  the  specific  authorized
programs,  and not from the general  revenues of the State or its taxing power.
Among the State  entities  authorized to issue such revenue bonds are the Texas
Water Development Board, the Texas Water Resources Finance Authority, the Texas
Agricultural  Finance  Authority,  the State Comptroller on behalf of the Texas
School  Facilities  Finance  Program,  the  Texas  Department  of  Housing  and
Community  Affairs,  the Texas  Department of Economic  Development,  the Texas
Turnpike  Authority,  the Texas Veteran's Land Board,  the Texas Public Finance
Authority,  the Texas Low-Level  Radioactive Waste Disposal Authority and Texas
colleges and universities. Effective September 1, 1997, the Texas Department of
Transportation received authority to issue revenue bonds.  Additionally,  as of
September 1, 1997, the name of the Texas  Department of Commerce was changed to
the Texas Department of Economic  Development.  The outstanding debt and assets
of the Texas Turnpike  Authority were  transferred to a newly created  regional
tollway authority,  the North Texas Tollway Authority,  effective  September 1,
1997.

     RECENT  DEVELOPMENTS  AFFECTING  STATE DEBT.  Texas Revised Civil Statutes
Article 717k-7(8)  prohibits the Legislature from authorizing  additional State
debt payable from general revenues, including authorized but unissued bonds and
lease purchase  contracts in excess of $250,000,  if the resulting  annual debt
service  exceeds  five  percent  of an amount  equal to the  average  amount of
general revenue for the three immediately  preceding years,  excluding revenues
constitutionally  dedicated  for purposes  other than payment of debt  service.
Pursuant to HJR 59, passed by the 75th  Legislature,  Proposition 11 proposed a
constitutional  amendment  to add the  provisions  of Article  717k-7(8) to the
Constitution. On November 4, 1997 Proposition 11 was passed.

     Although not  specifically a debt issue,  pursuant to HJR 8, passed by the
75th  Legislature,  Proposition  13 was submitted to Texas voters and passed on
November 4, 1997. Proposition 13 proposed a constitutional  amendment to extend
the State's full faith and credit to the Texas  Tomorrow  Fund and  established
the Fund as a  constitutionally  protected  fund.  The Texas  Tomorrow  Fund is
dedicated to the prepayment of higher education tuition and fees.

     SHORT TERM BORROWING. By statute, the Texas Comptroller of Public Accounts
is  authorized  to  make  interfund   transfers  of  surplus  cash,   excluding
constitutionally  dedicated revenues, between funds in the Treasury in order to
avoid  temporary cash  deficiencies in the General Revenue Fund. This procedure
effectively  allows the  Comptroller of Public  Accounts to borrow against cash
balances held in special funds to finance  deficiencies  in the General Revenue
Fund caused by timing differences  between cash receipts and cash expenditures.
During fiscal 1997 approximately  $2.9 billion in Tax and Revenue  Anticipation
Notes were issued by the  Comptroller.  The  Comptroller is authorized to issue
Tax and  Revenue  Anticipation  Notes  ("Notes")  on behalf of the State  under
legislation  which  became  effective in October  1986.  Under the terms of the
legislation,  Notes may be issued  solely to  coordinate  the State's cash flow
within a fiscal year and must mature and be paid in full during the biennium in
which the Notes are issued.  Interfund  borrowing  was not used in fiscal years
1996 and 1997 due to the  consolidation  of  numerous  funds  into the  General
Revenue Fund on August 31, 1993. The total amount of Notes issued and interfund
borrowing may not exceed 25 percent of the taxes and revenues to be credited to
the  State's  General  Revenue  Fund for the fiscal year as  forecasted  by the
Comptroller.

     Several  State  agencies  and   institutions  of  higher   education  (The
University of Texas and Texas A&M University) use commercial paper and variable
rate notes to provide financing for equipment, interim construction, and loans.
In fiscal 1997,  these entities issued $333 million in commercial paper to fund
their respective activities.

     SOURCES OF  REVENUE.  As a result of the  State's  expansion  in  Medicaid
spending  and  other  Health  and Human  Services  programs  requiring  federal
matching  revenues,  federal receipts were the State's leading source of income
in fiscal  1997.  Sales tax,  which had been the main source of revenue for the
previous twelve years prior to fiscal 1993, was second.  Licenses,  fees, fines
and  penalties  were the third  largest  revenue  source to the State in fiscal
1997. Motor fuels taxes and motor vehicle  sales/rental  taxes were the State's
fourth and fifth largest revenue sources. The remainder of the State's revenues
are derived  primarily from interest and investment  income,  lottery proceeds,
cigarette and tobacco,  franchise,  oil and gas severance and other taxes.  The
State has no personal or corporate income tax, although the State does impose a
corporate  franchise  tax based on the amount of a  corporation's  capital  and
"earned  surplus,"  which  includes  corporate  net  income and  officers'  and
directors' compensation.

     POTENTIAL FOR REDUCTION OF STATE  REVENUES AND DEBT SERVICE.  There can be
no assurance that the State will not face budget gaps, decreases in revenues or
deficits in future years resulting from a disparity

                                       9

between tax or other revenues  projected and the spending  required to maintain
State programs and debt service at current levels. Furthermore,  the State is a
party  to  numerous  lawsuits  in  which  an  adverse  decision  could  require
extraordinary and unbudgeted  expenditures.  These or other events could result
in the State's  inability to pay debt as it becomes due which could also affect
negatively the value of your investment in the Texas Funds. Notwithstanding the
foregoing, the State of Texas finished fiscal 1997 with a $2.7 billion positive
cash balance in the General Revenue Fund. This was the tenth  consecutive  year
that  Texas has ended a fiscal  year with a  positive  balance  in the  General
Revenue Fund.
    
     LIMITATIONS ON TAXING POWER. The Constitution prohibits the State of Texas
from levying ad valorem  taxes on property for general  revenue  purposes.  The
Constitution also limits the rate of growth of appropriations from tax revenues
not dedicated by the Constitution  during any biennium to the estimated rate of
growth for the State's  economy.  The Legislature may avoid the  constitutional
limitations if it finds,  by a majority vote of both houses,  that an emergency
exists.  The Constitution  authorizes the Legislature to provide by law for the
implementation  of this  restriction,  and the  Legislature,  pursuant  to such
authorization,  has defined the estimated rate of growth in the State's economy
to mean the estimated increase in personal income.
   
     APPROPRIATIONS  AND  BUDGETING.   The  Texas   Constitution   requires  an
appropriation  for  any  funds  to  be  drawn  out  of  the  Treasury.  Certain
appropriations  are  made  by  the  Constitution  and do  not  require  further
legislative  action,  although  the  Legislature  frequently  makes a  parallel
appropriation.  All other  appropriations must be made through a bill passed by
the Legislature and approved by the Governor or passed by the Legislature  over
the Governor's veto. Legislative appropriations are limited by the Constitution
to a period of two years.  Article III, Section 49a of the Texas  Constitution,
the so-called  "pay-as-you-go"  provision,  provides that an appropriation from
any fund other than the  General  Revenue  Fund is not valid if it exceeds  the
amount of cash and estimated revenues of the fund from which such appropriation
is to be paid. No appropriations that are passed by the Legislature may be sent
to the Governor for consideration  until the Comptroller of Public Accounts has
certified that the amounts  appropriated are within the amounts estimated to be
available in the affected funds.

     The  Governor  is  authorized  by  statute  to make  findings  of any fact
specified by the Legislature in any appropriations bill as a contingency to the
expenditure of funds. Accordingly,  the Governor has some minimal discretion to
prevent  the  expenditure  of  funds,  exercisable  in  situations  in which an
appropriation  made by the Legislature is conditioned  upon the occurrence of a
given event or the existence of a given fact.

     The  Legislature  has provided a means of dealing with fiscal  emergencies
under which the Governor is empowered to authorize  expenditures from a general
appropriation  made  by  the  Legislature  specifically  for  emergencies.  The
Legislature  is not obligated to appropriate  any amount for such purpose,  but
customarily  does so. The Governor may not  authorize  the  expenditure  of the
emergency  funds unless a  certification  is made to the  Comptroller of Public
Accounts that an emergency and imperative public necessity requiring the use of
such funds exists and the  Comptroller of Public  Accounts  determines  that no
other funds are available for such purpose.  Any  expenditure  so authorized by
the  Governor  may only be used in those  instances in which no other funds are
available for purposes  specifically  appropriated  by the  Legislature  due to
exhaustion of appropriations.

     The  Legislature,  in the second called  session held during the Summer of
1987,  enacted a budget  execution law which gave the Governor,  subject to the
review  of the  Legislative  Budget  Board,  the  ability  to make  changes  in
legislative  appropriations  during  periods  when  the  Legislature  is not in
session.  The  statute was amended in 1991,  giving both the  Governor  and the
Legislative  Budget Board the authority to make  proposals that require a State
agency be  prohibited  from  spending an  appropriation,  which require that an
agency be obligated to expend an  appropriation,  or which affect the manner in
which part or all of an appropriation  made by the Legislature to an agency may
be distributed or redistributed.  In addition,  the Governor or the Legislative
Budget Board, upon making a determination that an emergency exists, may propose
that an appropriation  made to a State agency be transferred to another agency,
that an  appropriation  be  retained  by the  agency  but used for a  different
purpose or that the time when an  appropriation  is made  available  to a State
agency  be  changed.  Funds  which are  dedicated  by the  Constitution  may be
withheld upon the Governor's or the Legislative  Budget Board's  proposal,  but
may not be  transferred to other State  agencies,  except to an agency which is
entitled  to receive  appropriations  from those  funds  under the terms of the
Constitution.  Federal  funds  appropriated  by the  Texas  Legislature  may be
transferred only as permitted by federal law. The Governor's or the Legislative
Budget Board's use of the budget  execution law is subject to publication  and,
in certain  instances,  public hearing  requirements.  In addition,  before the
Governor's  proposal  may be  executed,  it must be  ratified  by action of the
Legislative  Budget  Board,  or if proposed by the Board,  the proposal must be
ratified by the Governor.
    
     Except  under  the  circumstances  set  forth  above,   appropriations  or
adjustments  of  appropriations   may  currently  be  authorized  only  by  the
Legislature.

     PUBLIC SCHOOL FINANCE. In 1984, a group of property-poor  school districts
and the  Mexican-American  Legal Defense and Education  Fund filed  EDGEWOOD V.
BYNUM (later Kirby) against the school finance

                                      10
<PAGE>
system,  challenging the State's school finance system as unconstitutional.  In
April  1987  State  District  Judge  Harley  Clark  ruled  in  favor  of the 67
property-poor  districts  finding  the State's  public  school  funding  system
unconstitutional. Two subsequent school finance plans were drafted by the Texas
Legislature   in  June   1990  and   April   1991,   but   each  was   declared
unconstitutional.  In late May 1993,  Texas  legislators  passed Senate Bill 7,
which directed the State's 98 wealthiest  school districts to choose from among
five alternatives for sharing their overall property wealth with other,  poorer
districts. Judge McCown ordered that the plan be implemented during the 1993-94
school year and, on December 10, 1993, upheld the constitutionality of SB 7. On
May 25, 1994,  representatives  from property-rich and property-poor  districts
appealed the case to the Texas Supreme Court.

     The Texas Supreme Court issued its opinion on January 30, 1995.  The court
upheld all  provisions  of SB 7 and  overturned  the lower  court's  mandate to
provide  additional  funding for school facilities in property-poor  districts.
The court ruled that convincing  evidence of an inability to provide facilities
had not been presented,  but that the absence of a separate  funding source for
facilities  could  cause  the  court  to  declare  the  entire  finance  system
unconstitutional.   The  court  also   cautioned   of  the   appearance   of  a
constitutionally-prohibited  State ad valorem tax if all districts  were forced
to tax at the capped value to maintain standards.
   
     RETIREMENT  SYSTEMS.  The State of Texas  operates  three  defined-benefit
retirement  systems:  the  Teacher  Retirement  System of Texas  ("TRST"),  the
Employee's  Retirement  System of Texas  ("ERST") and the  Judicial  Retirement
System  of  Texas  ("JRST").  In  addition,   State  employees,   except  those
compensated  on a fee basis,  are  covered  under the federal  Social  Security
system.  Political  subdivisions  of the  State  may  voluntarily  provide  for
coverage of their employees under the State's agreement with the federal Social
Security Administration.

     TRST and ERST are maintained on an actuarial basis. As of August 31, 1997,
the unfunded actuarial  liability of TRST was approximately  $145.8 million and
the overfunded  actuarial liability of ERST was approximately $399 million. The
period  required to amortize the unfunded  actuarial  liability of TRST,  given
then-current  contribution  rates,  benefits and  investment  assumptions,  was
estimated to be .6 years. The TRST fair value of investments,  as of August 31,
1997, was $61.5 billion. The ERST fair value of pooled investments as of August
31,  1997,  was  $15.2  billion.  Prior  to  1985,  JRST  was  maintained  on a
pay-as-you-go basis. However, legislation enacted in 1985 divided JRST into two
plans by changing  the name of the  existing  plan and  establishing  a second,
separate plan. The new plan, known as Judicial  Retirement System of Texas Plan
Two, is maintained on an  actuarially  sound basis and covers  individuals  who
became  judicial  officers  after  August  31,  1985.  The  unfunded  actuarial
liability  of JRST Plan Two as of August 31,  1997,  the most recent  valuation
date, was $4 million.  The old plan, known as the Judicial Retirement System of
Texas Plan One, is  maintained  on a  pay-as-you-go  basis and covers  judicial
officers  who are active on August 31,  1985,  or had retired on or before that
date.

     Contributions  to the  retirement  systems  are made by both the State and
covered employees. The Texas Constitution mandates a State contribution rate of
not less than 6 percent or more than 10  percent  of  payroll  for the ERST and
TRST;  member  contributions  may not be less than 6 percent  of  payroll.  The
Legislature,  however,  may  appropriate  additional  funds as are  actuarially
determined to be needed to fund benefits authorized by law.
    
     For  the  1996-97   biennium,   the  Texas  Legislature  set  the  State's
contribution  rates to the retirement  systems at the following rates: ERST and
TRST at 6 percent of  payroll,  and JRST Plan Two at 16.54  percent of payroll.
Member  contribution  rates  are 6  percent  for ERST and JRST Plan Two and 6.4
percent for TRST.

     As part  of the  1985  changes  in the  State's  retirement  systems,  the
Legislature  prohibited  the  implementation  of  changes  in the ERST and TRST
systems that would cause the period required to amortize the unfunded actuarial
liability of either plan to exceed thirty-one  years.  Prior to the adoption of
these measures,  the State had no official limit on the amortization period for
unfunded actuarial liability, although the management of both ERST and TRST had
adopted an informal policy of limiting the period to thirty years.

     The State's  retirement  systems were created and are operated pursuant to
statutes  enacted by the  Legislature.  The  Legislature  has the  authority to
modify these statutes and, accordingly,  contribution rates, benefits,  benefit
levels and such other aspects of each system as it deems appropriate, including
the  provisions  limiting  changes that  increase the  amortization  period for
unfunded  actuarial  liability of any plan. The State's  retirement systems are
not subject to the funding and vesting  requirements of the Employee Retirement
Income  Security Act of 1974,  as amended,  although  Congress has from time to
time considered legislation that would regulate pension funds of public bodies.

                             PORTFOLIO TRANSACTIONS

The  Manager,  pursuant to the  Advisory  Agreement  dated June 25,  1993,  and
subject to the general  control of the Trust's  Board of  Trustees,  places all
orders  for  the  purchase  and  sale  of Fund  securities.  Purchases  of Fund
securities are made either directly from the issuer or from dealers who deal in
tax-exempt

                                      11
<PAGE>
securities.  The  Manager  may  sell  Fund  securities  prior  to  maturity  if
circumstances  warrant and if it believes such  disposition  is  advisable.  In
connection  with  portfolio  transactions  for the Trust,  the Manager seeks to
obtain  the best  available  net price  and most  favorable  execution  for its
orders.  The Manager has no agreement or commitment to place  transactions with
any  broker-dealer  and no regular  formula is used to  allocate  orders to any
broker-dealer.  However,  the Manager may place security orders with brokers or
dealers who furnish  research or other services to the Manager as long as there
is no sacrifice in obtaining the best overall terms available. Payment for such
services  would be generated  only  through  purchase of new issue fixed income
securities.

     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.  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.

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

PORTFOLIO TURNOVER RATE

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.

     The rate of  portfolio  turnover  will not be a limiting  factor  when the
Manager deems changes in the Texas Tax-Free Income Fund's portfolio appropriate
in view of its  investment  objective.  For example,  securities may be sold in
anticipation  of a rise in interest  rates  (market  decline) or  purchased  in
anticipation  of a decline in interest  rates  (market rise) and later sold. In
addition, a security may be sold and another security of comparable quality may
be purchased at approximately  the same time in order to take advantage of what
the Fund believes to be a temporary  disparity in the normal yield relationship
between the two securities.  These yield  disparities may occur for reasons not
directly related to the investment  quality of particular issues or the general
movement of interest rates, such as changes in the overall demand for or supply
of various types of tax-exempt securities.

     For the last two fiscal years the Texas Tax-Free  Income Fund's  portfolio
turnover rates were as follows:
   
           1997 . . . . .86.17%            1998 . . . . . 56.29%
    
     Portfolio  turnover  rates  have  been  calculated   excluding  short-term
variable rate securities,  which are those with put date intervals of less than
one year.
   
                             DESCRIPTION OF SHARES

The Funds are series of the Trust and are diversified. The Trust is an open-end
management investment company established as a business trust under the laws of
the State of Delaware pursuant to a Master Trust Agreement dated June 21, 1993.
The Trust is  authorized  to issue  shares of  beneficial  interest in separate
portfolios.  Four  such  portfolios  have  been  established,  two of which are
described in this SAI. Under the Master Trust Agreement,  the Board of Trustees
is  authorized to create new  portfolios in addition to those already  existing
without shareholder approval.
    
                                      12
<PAGE>
     Each  Fund's  assets  and all  income,  earnings,  profits,  and  proceeds
thereof, subject only to the rights of creditors, are specifically allocated to
such Fund. They constitute the underlying  assets of each Fund, are required to
be segregated on the books of account,  and are to be charged with the expenses
of such Fund.  Any general  expenses of the Trust not readily  identifiable  as
belonging  to a  particular  Fund are  allocated  on the  basis  of the  Funds'
relative net assets during the fiscal year or in such other manner as the Board
determines  to be fair and  equitable.  Each share of each Fund  represents  an
equal  proportionate  interest  in that  Fund  with  every  other  share and is
entitled to dividends and distributions out of the net income and capital gains
belonging to that Fund when declared by the Board.
   
     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. The Trust 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.  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.
The Trust will assist in communicating to other shareholders about the meeting.
On any matter submitted to the  shareholders,  the holder of each Fund share is
entitled  to one vote per  share  (with  proportionate  voting  for  fractional
shares)  regardless  of the  relative  net asset  values of the Funds'  shares.
However,  on matters  affecting  an  individual  Fund,  a separate  vote of the
shareholders of that Fund is required.  Shareholders of a Fund are not entitled
to vote on any  matter  which does not  affect  that Fund but which  requires a
separate vote of another Fund.  Shares do not have  cumulative  voting  rights,
which means that holders of more than 50% of the shares voting for the election
of Trustees can elect 100% of the Trust's Board of Trustees, and the holders of
less than 50% of the shares  voting for the  election of  Trustees  will not be
able to elect any person as a Trustee.
    
     Shareholders of a particular Fund might have the power to elect all of the
Trustees of the Trust because that Fund has a majority of the total outstanding
shares of the  Trust.  When  issued,  each  Fund's  shares  are fully  paid and
nonassessable,  have no  pre-emptive  or  subscription  rights,  and are  fully
transferable. There are no conversion rights.

                   CERTAIN FEDERAL INCOME 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) and (2) satisfy certain diversification
requirements  at the  close  of  each  quarter  of  the  Fund's  taxable  year.
Furthermore,  to pay tax-exempt interest income dividends,  at least 50% of the
value of each Fund's  total  assets at the close of each quarter of its taxable
year must consist of  obligations  the interest of which is exempt from federal
income tax. Each 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
this excise tax.
   
     For federal income tax purposes,  debt  securities  purchased by the Funds
may be treated as having  original  issue  discount.  Original  issue  discount
represents interest income for federal income tax purposes and can generally be
defined as the  excess of the stated  redemption  price at  maturity  of a debt
obligation over the issue price. Original issue discount is treated for federal
income  tax  purposes  as earned by the  Funds,  whether  or not any  income is
actually received, and therefore is subject to the distribution requirements of
the  Code.  However,   original  issue  discount  with  respect  to  tax-exempt
obligations generally will be excluded from the Funds' taxable income, although
such  discount  will be included in gross  income for  purposes of the 90% test
described  previously.  Original  issue  discount  with  respect to  tax-exempt
securities  is accrued and added to the adjusted  tax basis of such  securities
for purposes of

                                      13
<PAGE>
determining  gain or loss upon sale or at  maturity.  Generally,  the amount of
original  issue  discount  is  determined  on the basis of a constant  yield to
maturity  which takes into  account the  compounding  of accrued  interest.  An
investment in a stripped bond or stripped  coupon will result in original issue
discount.
    
     Debt securities may be purchased by the Funds at a market discount. Market
discount  occurs when a security is purchased at a price less than the original
issue price  adjusted for accrued  original issue  discount,  if any. The Funds
intend to defer  recognition of accrued market discount until maturity or other
disposition  of the bond. For securities  purchased at a market  discount,  the
gain realized on disposition  will be treated as taxable ordinary income to the
extent it does not exceed accrued market discount on the bond.

     The Funds may also  purchase  debt  securities  at a premium,  i.e.,  at a
purchase price in excess of face amount. With respect to tax-exempt securities,
the premium must be amortized to the maturity  date but no deduction is allowed
for the premium amortization. The amortized bond premium will reduce the Funds'
adjusted tax basis in the securities.  For taxable securities,  the premium may
be amortized if the Funds so elect. The amortized premium on taxable securities
is first offset against interest received on the securities and then allowed as
a deduction,  and, for  securities  issued after  September  27, 1985,  must be
amortized under an economic accrual method.

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.  It is expected that none of the Funds'
distributions will qualify for the corporate dividends-received deduction.

     To the extent that a Fund's  dividends  distributed  to  shareholders  are
derived from interest  income exempt from federal income tax and are designated
as  "exempt-interest  dividends"  by a Fund,  they  will be  excludable  from a
shareholder's  gross income for federal income tax purposes.  Shareholders  who
are recipients of Social Security benefits should be aware that exempt-interest
dividends received from a 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.

     A  shareholder  of the Texas  Tax-Free  Income Fund should be aware that a
redemption  of shares  (including  any  exchange  into  another USAA Fund) is a
taxable event and, accordingly,  a capital gain or loss may be recognized. 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 redemption or
exchange  will be disallowed  to the extent of such  exempt-interest  dividend.
Similarly,  if a  shareholder  of the Fund receives a  distribution  taxable as
long-term  capital  gain with  respect  to shares  of the Fund and  redeems  or
exchanges shares before he has held them for more than six months,  any loss on
the  redemption or exchange (not  otherwise  disallowed as  attributable  to an
exempt-interest dividend) will be treated as long-term capital loss.

     The Funds 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 the AMT and the  amount  of any tax to be  paid.  For
corporate investors,  alternative minimum taxable income is increased by 75% of
the amount by which adjusted current earnings (ACE) exceeds alternative minimum
taxable  income  before  the  ACE  adjustment.  For  corporate  taxpayers,  all
tax-exempt  interest is considered in  calculating  the AMT as part of the ACE.
Prospective investors should consult their own tax advisers with respect to the
possible application of the AMT to their tax situation.

     Opinions  relating  to the  validity  of  tax-exempt  securities  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 Funds'
counsel makes any review of the basis of such opinions.

                       TRUSTEES AND OFFICERS OF THE TRUST
   
The Board of Trustees of the Trust consists of seven Trustees who supervise the
business affairs of the Trust. Set forth below are the Trustees and officers of
the Trust, and their respective  offices and principal  occupations  during the
last five years.  Unless otherwise  indicated,  the business address of each is
9800 Fredericksburg Road, San Antonio, TX 78288.

                              THE TRUST'S MANAGER
   
As described  in the  Prospectus,  USAA  Investment  Management  Company is the
Manager  and  investment   adviser,   providing  services  under  the  Advisory
Agreement.  The Manager, an affiliate of United Services Automobile Association
(USAA), a large,  diversified financial services institution,  was organized in
May 1970 and has served as investment  adviser and  underwriter  for USAA State
Tax-Free Trust from its inception.

                                      17
<PAGE>
     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 Investment  Trust,  USAA Mutual Fund, Inc., USAA Tax Exempt Fund, Inc.;
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,  the Trust has agreed to pay the
Manager a fee computed as described  under FUND  MANAGEMENT in the  Prospectus.
Management fees are computed and accrued daily and 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 (if any); expenses of issuance and redemption of shares;
charges of transfer agents, custodians, and dividend disbursing agents; cost 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  persons  (not  affiliated)  of the  Manager;  costs of printing and
mailing the Prospectus, SAI, and periodic reports to existing shareholders; and
any other  charges or fees not  specifically  enumerated.  The Manager pays the
cost of printing and mailing copies of the Prospectus,  the SAI, and reports to
prospective shareholders.
   
     The Advisory Agreement will remain in effect until June 30, 1999, 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 in 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. Any such waiver or reimbursement  may be terminated by the Manager at any
time without prior notice to shareholders.  The Manager has voluntarily  agreed
to limit each Fund's  annual  expenses to .50% of its ANA until August 1, 1999,
and will reimburse the Funds for all expenses in excess of the limitations.
    
     For the last three fiscal years, management fees were as follows:
   
                                           1996            1997           1998
                                           ----            ----           ----
     Texas Tax-Free Income Fund          $35,729         $47,582        $76,602
     Texas Tax-Free Money Market Fund    $22,664         $25,483        $27,561

     Because the Funds'  expenses  exceeded  the  Manager's  voluntary  expense
limitation,  the Manager did not receive any management fees for the last three
fiscal years with respect to the Texas Tax-Free Money Market Fund. With respect
to the Texas  Tax-Free  Income Fund, the Manager did not receive any management
fees  for  1996 or  1997.  For 1998 the  Manager  did not  receive  $73,972  in
management fees to which it would have been entitled. In addition,  the Manager
did not receive  reimbursement  for other operating  expenses to which it would
have been entitled as follows:

                                           1996            1997           1998
                                           ----            ----           ----
     Texas Tax-Free Income Fund          $47,505         $32,878           --
     Texas Tax-Free Money Market Fund    $46,368         $39,351        $20,096
    
UNDERWRITER

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

TRANSFER AGENT

The  Transfer  Agent  performs  transfer  agent  services for the Trust under a
Transfer Agency Agreement.  Services include maintenance of shareholder account
records,  handling of communications  with  shareholders,  distribution of Fund
dividends, and production of reports with respect to account activity for

                                      18
<PAGE>
shareholders  and the  Trust.  For  its  services  under  the  Transfer  Agency
Agreement,  each Fund pays the  Transfer  Agent an annual  fixed fee of $26 per
account. The fee is subject to change at any time.

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

INDEPENDENT AUDITORS

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

                        CALCULATION OF PERFORMANCE DATA
   
Information  regarding  total  return and yield of each Fund is provided  under
COULD THE VALUE OF YOUR INVESTMENT IN THESE FUNDS FLUCTUATE? in the Prospectus.
See VALUATION OF SECURITIES herein for a discussion of the manner in which each
Fund's price per share is calculated.
    
TOTAL RETURN

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

                                P(1 + T)n = ERV

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

     The  calculation  assumes all 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.
   
     The date of  commencement of operations for the Texas Tax-Free Income Fund
was August 1, 1994. The Fund's average total returns for the following  periods
ended March 31, 1998, were:

        1 year . . . . 13.71%           Since inception . . . . 9.76%
    
YIELD

The Texas Tax-Free  Income Fund may advertise  performance in terms of a 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[((a-b)/(cd)+1)^6 -1]

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

     For purposes of the yield  calculation,  interest income is computed based
on the yield to maturity of each debt  obligation  in the Fund's  portfolio and
all recurring charges are recognized.

                                      19
<PAGE>
   
     The Fund's 30-day yield for the period ended March 31, 1998, was 4.70%.
    
YIELD - TEXAS TAX-FREE MONEY MARKET FUND
   
When the Texas Tax-Free Money Market Fund 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 and income other than
investment income, 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
Fund'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 Fund'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 March 31, 1998, was 3.37%.
       Effective Yield for 7-day Period ended March 31, 1998, was 3.43%.
    
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. The Texas  Tax-Free Money Market Fund may advertise  performance in terms
of a tax equivalent  yield based on the 7-day yield or effective  yield and the
Texas Tax-Free  Income Fund may advertise  performance in terms of a 30-day tax
equivalent yield.

     To calculate a tax  equivalent  yield,  the Texas  investor  must know his
federal  marginal income tax rate. The tax equivalent yield is then computed by
dividing  the  tax-exempt  yield  of a fund by the  complement  of the  federal
marginal tax rate. The complement,  for example, of a federal marginal tax rate
of 36.0% is 64.0%, that is (1.00-0.36=0.64).

    Tax Equivalent Yield = Tax Exempt Yield / (1- Federal Marginal Tax Rate)
   
     Based on federal marginal tax rate of 36.0%, the tax equivalent yields for
the Texas Tax-Free  Income and Texas Tax-Free Money Market Funds for the period
ended March 31, 1998, were 7.34% and 5.27%, respectively.
    
              APPENDIX A - TAX-EXEMPT SECURITIES AND THEIR RATINGS

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 Notes.

                                      20

     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 IBCA, Inc. (Fitch),  Duff & Phelps Inc., and
Thompson  BankWatch,  Inc.,  represent  their  opinions  of the  quality of the
securities rated by them. 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.

I. LONG-TERM DEBT RATINGS:

MOODY'S INVESTOR SERVICES, INC.
    
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 risk appear somewhat larger than in Aaa securities.

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

Baa      Bonds which are rated Baa are considered as  medium-grade  obligations
         (i.e., they are neither highly protected nor poorly secured). Interest
         payments and principal  security  appear  adequate for the present but
         certain    protective    elements   may   be   lacking   or   may   be
         characteristically  unreliable  over any great  length  of time.  Such
         bonds lack  outstanding  investment  characteristics  and in fact have
         speculative characteristics as well.
   
NOTE:  MOODY'S APPLIES  NUMERICAL  MODIFIERS 1, 2, AND 3 IN EACH GENERIC RATING
CLASSIFICATION.  THE  MODIFIER 1  INDICATES  THAT THE  OBLIGATION  RANKS IN THE
HIGHER END OF ITS GENERIC RATING CATEGORY, THE MODIFIER 2 INDICATES A MID-RANGE
RANKING,  AND THE  MODIFIER  3  INDICATES  A  RANKING  IN THE LOWER END OF THAT
GENERIC RATING CATEGORY.

STANDARD & POOR'S RATINGS GROUP

AAA       An obligation rated AAA has the highest rating assigned by Standard &
          Poor's.  The obligor's  capacity to meet its financial  commitment on
          the obligation is EXTREMELY STRONG.

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

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

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

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

FITCH IBCA, INC.

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

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

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

                                      21
<PAGE>
BBB       Good credit quality. "BBB" ratings indicate that there is currently a
          low  expectation  of credit risk.  The capacity for timely payment of
          financial commitments is considered adequate,  but adverse changes in
          circumstances  and in economic  conditions  are more likely to impair
          this capacity. This is the lowest investment-grade category.

PLUS 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, INC.

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

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

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

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

2. SHORT-TERM DEBT RATINGS:

MOODY'S STATE AND TAX-EXEMPT NOTES

MIG-1/VMIG1   This  designation  denotes best quality.  There is present strong
              protection by established cash flows,  superior liquidity support
              or demonstrated broad-based access to the market for refinancing.

MIG-2/VMIG2   This designation denotes high quality.  Margins of protection are
              ample although not so large as in the preceding group.

MOODY'S COMMERCIAL PAPER

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

              o Leading market positions in well-established industries.

              o High rates of return on funds employed.

              o Conservative  capitalization  structures with moderate reliance
                on debt and ample asset protection.

              o Broad margins in earning  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   promissory
              obligations.  This  will  normally  be  evidenced  by many of the
              characteristics  cited  above  but to a lesser  degree.  Earnings
              trends and coverage  ratios,  while sound, may be more subject to
              variation.    Capitalization    characteristics,    while   still
              appropriate,  may be more affected by external conditions.  Ample
              alternate liquidity is maintained.

S&P TAX-EXEMPT NOTES

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

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

S&P COMMERCIAL PAPER

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

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

FITCH'S COMMERCIAL PAPER, CERTIFICATES OF DEPOSIT AND TAX-EXEMPT NOTES

F1        Highest credit quality.  Indicates the strongest  capacity for timely
          payment of financial commitments; may have an added "+" to denote any
          exceptionally strong credit features.

F2        Good credit  quality.  A satisfactory  capacity for timely payment of
          financial commitments, but the margin of safety is not as great as in
          the case of the higher ratings.

F3        Fair credit  quality.  The capacity  for timely  payment of financial
          commitments is adequate;  however,  near-term  adverse  changes could
          result in a reduction to non-investment grade.

                                      22
<PAGE>
DUFF & PHELPS COMMERCIAL PAPER

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.

THOMPSON BANKWATCH, INC.

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

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

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

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

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

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

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

Item 24.      PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE FUND

              Information  pertaining to persons  controlled by or under common
              control with  Registrant is hereby  incorporated  by reference to
              the section captioned "Fund Management" in the Prospectus and the
              section  captioned  "Trustees  and  Officers of the Trust" in the
              Statement of Additional Information.

Item 25.      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 TRUSTEE 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 directors, officers
              or trustees of another  organization  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 Covered  Person may be or may have been  involved as a party
              or  otherwise  or with 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 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  (such
              conduct  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 Covered Person 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 from funds attributable
              to 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  the  Registrant  in  question  if  it is
              ultimately  determined that  indemnification  of such expenses is
              not  authorized  under this Article VI 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

                                      C-3
<PAGE>
              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  who  are not
              parties 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  from 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  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  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.

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

Attention: Michael J.C. Roth, President

Gentlemen:

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

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

     2. PURPOSE AND  LIMITATIONS  ON  BORROWINGS.  Each  Borrower  will use the
proceeds of each Loan made to it solely for temporary or emergency  purposes of
the Fund for whose  benefit it is  borrowing  in  accordance  with such  Fund's
Borrowing Limit (Schedule A) and prospectus in effect at the time of such Loan.
Portfolio  securities  may not be  purchased  by a Fund  while  there is a Loan
outstanding  under the Facility or any other facility,  if the aggregate 
<PAGE>
amount of such Loan and any other such loan  exceeds 5% of the total  assets of
such Fund.

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

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

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

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

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

                                       2
<PAGE>
     8. UNCOMMITTED FACILITY. The Borrowers acknowledge that the Facility is an
uncommitted  facility and that CAPCO shall have no  obligation to make any Loan
requested during the Facility Period under this Agreement. Further, CAPCO shall
not make any Loan if this Facility has been terminated by the Borrowers,  or if
at the time of a request for a Loan by a Borrower (on behalf of the  applicable
Fund(s)) there exists any Event of Default or condition which, with the passage
of time or giving of notice,  or both,  would  constitute or become an Event of
Default with respect to such Borrower (or such applicable Fund(s)).

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

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

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

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

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

                                       3
<PAGE>
         (c) CAPCO shall make appropriate entries on the Note or the records of
CAPCO to reflect the Terms of the Loan; provided,  however, that the failure to
do so shall not affect the obligation of any Borrower.

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

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

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

         (a)  ORGANIZATION,  STANDING,  ETC. The Borrower is a  corporation  or
trust duly organized,  validly existing,  and in good standing under applicable
state laws and has all  requisite  corporate  or trust power and  authority  to
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
CAPCO 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 CAPCO by such Borrower or the
applicable  Funds in  connection  with  the  transactions  contemplated  hereby
contain any untrue  statement of a material  fact or omit to state any material
fact necessary to make the statements  contained  herein or therein in light of
the circumstances when made not misleading;

                                       4
<PAGE>
         (c) AUTHORIZATION;  COMPLIANCE WITH OTHER INSTRUMENTS.  The execution,
delivery  and  performance  of this  Agreement  and the  Note,  and  borrowings
hereunder, have been duly authorized by all necessary corporate or trust action
of the Borrower and will not result in any  violation of or be in conflict with
or  constitute  a  default  under  any term of the  charter,  by- laws or trust
agreement  of  such  Borrower  or the  applicable  Funds,  or of any  borrowing
restrictions  or  prospectus  or statement of  additional  information  of such
Borrower or the applicable  Funds, or of any agreement,  instrument,  judgment,
decree,  order,  statute,  rule or governmental  regulation  applicable to such
Borrower,  or  result  in  the  creation  of  any  mortgage,  lien,  charge  or
encumbrance  upon any of the  properties  or  assets  of such  Borrower  or the
applicable  Funds  pursuant to any such term.  The Borrower and the  applicable
Funds are not in violation of any term of their respective charter,  by-laws or
trust  agreement,  and  such  Borrower  and  the  applicable  Funds  are not in
violation of any material term of any agreement or instrument to which they are
a party, or to the best of such Borrower's knowledge, of any judgment,  decree,
order, statute, rule or governmental regulation applicable to them;

         (d) SEC  COMPLIANCE.  The  Borrower  and the  applicable  Funds are in
compliance in all material  respects  with all federal and state  securities or
similar laws and  regulations,  including all material  rules,  regulations and
administrative orders of the Securities and Exchange Commission (the "SEC") and
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 is irrevocably  paid in full, and until the Facility
is terminated, such Borrower (for itself and on behalf of its respective Funds)
agrees:

Operations and Statements of Changes in Net Assets of each  applicable Fund for

         (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

         (d) To do, or cause to be done,  all things  necessary to preserve and

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

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

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

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

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

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

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

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

         (e) Any  representation  or warranty made by a Borrower or Fund herein
or 
                                       7
<PAGE>
pursuant  hereto  shall prove to have been false or  incorrect  in any material
respect when made;

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

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

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

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

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

                                       8
<PAGE>
and owing  thereon or such other Fund's share of any other amount due hereunder
and under the Note (as determined in accordance with the provisions hereof).

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

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

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

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

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

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

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

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

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

Sincerely,

USAA CAPITAL CORPORATION

                          MASTER GRID PROMISSORY NOTE

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

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

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

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

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

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

     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  Master Revolving  Credit  Facility
Agreement between the Borrowers and NationsBank of Texas,  N.A.  (NationsBank),
dated  January  14,  1998,  in the  manner  and to the  extent set forth in the
Agreement among the Borrowers, CAPCO and NationsBank, dated January 14, 1998.

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

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

Attention:  Michael J.C. Roth, President

Gentlemen:

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

     1.  AMOUNT.  The  aggregate principal  amount of  the Loans to be advanced
under this  Facility shall not exceed, at any one time outstanding, One Hundred
Million  United States  Dollars  (U.S. $100,000,000)  (the  "Commitment").  The
aggregate principal amount of the Loans which may be
<PAGE>
borrowed by a Borrower for the benefit of a particular Fund under  the Facility
and the  Other Facility (hereinafter  defined) shall  not exceed the percentage
(the  "Borrowing  Limit")  of the  total assets  of such  Fund as  set forth on
Schedule A hereto.

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

     3.  BORROWING RATE  AND MATURITY OF  LOANS.  The principal  amount of  the
Loans outstanding  from time to  time shall bear  interest at a rate per  annum
equal to, at the option of the applicable Borrower(s), (i) the aggregate of the
Federal Funds Rate (as defined below) plus .125 of one percent (1%) (12.5 basis
points) or (ii) the aggregate of the London Interbank Offered Rate (as  defined
below)  plus  12.5  basis  points.   The  rate  of  interest  payable  on  such
outstanding amounts shall change on each date that the Federal Funds Rate shall
change.  Interest  on the  Loans shall  be calculated on the basis of a year of
360 days and  the actual days elapsed  but shall not  exceed the highest lawful
rate.  Each  Loan will be for  an established  number of days to be agreed upon
by  the  applicable  Borrower(s) and  the  Bank  and,  in  the  absence of such
agreement, will  mature on  the earlier  of three months after the date of such
Loan  or the  last day of the Facility Period.   The term "Federal Funds Rate,"
as  used herein,  shall mean  the overnight rate for Federal funds transactions
between member banks of the Federal Reserve System, as published by the Federal
Reserve Bank  of New York or, if  not so published, as determined in good faith
by the Bank in  accordance with  its customary  practices; and the term "London
Interbank Offered Rate," as used herein, shall mean the rate per 
<PAGE>
annum at  which United  States dollar  deposits are  offered by the Bank in the
London  interbank market  at approximately  11:00 a.m. London time two business
days prior to the first day of the interest period (of 7 or 14 days or one, two
or three months as selected by the Borrower(s)) for which  the London Interbank
Offered Rate  is to be  in effect, as adjusted by the Bank in good faith and in
accordance  with its  customary practices  for any reserve costs imposed on the
Bank  under Federal  Reserve Board Regulation  D with respect to "Euro-currency
Liabilities".  The  London  Interbank  Offered  Rate  shall  not  be  available
hereunder if it would be unlawful  for the Bank to make or maintain Loans based
on such rate or if such rate  does not, in the good faith judgment of the Bank,
fairly reflect the cost to the Bank of making or maintaining Loans.  The London
Interbank Offered Rate shall not be available for any interest period which, if
such  rate  were available,  would begin  after the  occurrence and  during the
continuation of an Event of Default (as defined below).  Any past due principal
and/or  accrued interest  shall bear  interest at a rate per annum equal to the
aggregate of the Federal Funds Rate plus 1.125 percent (112.5 basis points) and
shall be  payable on  demand.  If the applicable Borrowers do not affirmatively
elect  to have  a Loan or  Loans bear  interest based  on the  London Interbank
Offered Rate  at least  two business  days prior to the first day of a possible
interest  period applicable  thereto, such  Loan or  Loans shall  bear interest
based on the Federal Funds Rate until such election is affirmatively made.

     4.  ADVANCES,  PAYMENTS, PREPAYMENTS AND READVANCES.  Upon each Borrower's
request, and  subject to  the terms  and conditions  contained herein, the Bank
shall  make Loans  to each  Borrower on  behalf of  and for  the benefit of its
respective  Fund(s) during  the Facility  Period, and each Borrower may borrow,
repay  and reborrow  funds hereunder.  The  Loans shall  be evidenced by a duly
executed  and delivered  Master Grid Promissory  Note in the form of EXHIBIT A.
Each  Loan shall be  in an aggregate  amount not less than One Hundred Thousand
United States  Dollars (U.S. $100,000)  and increments  of One Thousand  United
States  Dollars (U.S. $1,000)  in excess  thereof.  Payment  of  principal  and
interest due with respect to each Loan shall be payable at the maturity of such
Loan  and shall  be made in  funds immediately available to the Bank prior to 2
p.m. Dallas time on the day such payment is due, or as the Bank shall otherwise
direct  from time to time and, subject  to the terms and conditions hereof, may
be repaid with the proceeds of a new borrowing hereunder.  Notwithstanding  any
provision  of this  Agreement to  the contrary,  all Loans,  accrued but unpaid
interest  and other  amounts payable  hereunder shall  be due  and payable upon
termination of the Facility (whether by  
<PAGE>
acceleration or  otherwise).   If any Loan bearing interest based on the London
Interbank Offered  Rate is repaid or prepaid  other than on the last  day of an
interest  period applicable thereto,  the Fund which is the beneficiary of such
Loan  shall pay  to the  Bank promptly  upon demand  such amount  as  the  Bank
determines in good faith is necessary to compensate the Bank for any reasonable
cost  or  expense  incurred  by  the  Bank  as  a  result  of such repayment or
prepayment  in connection with  the reemployment of funds in an amount equal to
such  repayment or  prepayment.  Whenever the Bank seeks to assess for any such
cost or  expense it  will  provide  a  certificate  as  the  Borrower(s)  shall
reasonably request.

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

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

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

     8.  COMMITTED  FACILITY.  The  Bank  acknowledges  that the  Facility is a
committed  facility  and that  the Bank  shall be  obligated  to make  any Loan
requested during the Facility Period under this Agreement, subject to the
<PAGE>
terms  and conditions  hereof;  provided, however,  that the  Bank shall not be
obligated  to make  any Loan  if this  Facility  has  been  terminated  by  the
Borrowers,  or if  at the time of a request for a Loan by a Borrower (on behalf
of  the  applicable  Fund(s))  there  exists any  Event of Default or condition
which, with the passage of time or giving of notice, or both, would  constitute
or become an Event of Default with respect to such Borrower (or such applicable
Fund(s)).

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

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

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

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

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

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

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

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

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

          (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

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  result  in  the  creation  of  any  mortgage,  lien,  charge  or
encumbrance  upon any  of the  properties  or assets   of such Borrower  or the
applicable  Funds pursuant  to any such  term.  The Borrower and the applicable
Funds are not in violation of any  term of their respective charter, by-laws or
trust  
<PAGE>
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

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:

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

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

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

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

of the Bank,  which consent will not be  unreasonably withheld; provided that a
Borrower  may  without  such  consent  merge,  consolidate  with,  or  purchase
substantially all of the assets of, or sell substantially all of its assets to,
an  affiliated investment  company or series  thereof, as provided  for in Rule
17a-8 of the Investment Company Act of 1940.

     15.  EVENTS OF DEFAULT.  If any of the following events (each an "Event of
Default") shall  occur (it being  understood  that  an Event  of  Default  with
respect  to one Fund  or Borrower shall not constitute an Event of Default with
respect to any other Fund or Borrower):
<PAGE>
          (a)  Any Borrower  or Fund shall default in  the payment of principal
or interest on any Loan or any other fee due hereunder for a period of five (5)
days  after the  same becomes  due and  payable, whether  at maturity  or  with
respect to the Facility Fee at a date fixed for the payment thereof;

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

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

          (d)  Any  Borrower or  Fund  shall  default  in  the  performance  or

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     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.

U.S. $100,000,000                                      Dated:  January 14, 1998

     FOR  VALUE  RECEIVED,  each of  the undersigned  (each  a  "Borrower"  and
collectively  the "Borrowers"), severally and not jointly, on behalf of and for
the benefit of  the series  of funds comprising each such Borrower as listed on
Schedule A  to the  Agreement as  defined below (each a "Fund" and collectively
the "Funds")  promises to  pay to the order  of NATIONSBANK OF TEXAS, N.A. (the
"Bank") at the Bank's office located at 901 Main Street, Dallas, Dallas County,
Texas  75202, in lawful  money of the  United States of America, in immediately
available  funds, the principal  amount of all  Loans made by  the Bank to such

Letter dated January 14, 1998 (as amended or  modified, the "Agreement"), among
the Borrowers and the Bank, 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.

     The Bank 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  the  Bank  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.

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

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.

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

NationsBank of Texas, N.A.             Agreement

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

Name and Address of Lender (Including County):

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

  (Lender)

Name and Address of Borrower:

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

  (Debtor)

Name and Address of Creditor:

USAA Capital Corporation
9800 Fredericksburg Road
San Antonio, Texas  78288

  (Creditor)

1.  Background.   Debtor is or  may be  indebted to  Lender  pursuant  to  that
    certain Facility Agreement Letter dated January 14, 1998 between Debtor and
    Lender ("Senior Facility Agreement").  Debtor also is or may be indebted to
    Creditor  pursuant to  that certain Facility Agreement Letter dated January
    13, 1998  between Debtor  and Creditor ("Subordinated Facility Agreement").
    All debt  (as hereinafter defined)  under 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 o f all other
    rights  and securities  of the  Lender.   No waiver by  Lender of any right
    hereunder, with respect to a particular payment, shall affect or impair its
    rights in any matters thereafter occurring.

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

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